Structure and Principle of Z Vertical Conveyor

The structure of the z-type bucket conveyor is similar to the traditional vertical bucket elevator. They both use chain buckets for conveying. But there is some difference in the feeding and discharging. Z style elevator conveyor increases the conveying part of the upper and lower horizontal sections (the shortest 1.5 метара). So it is convenient for customers to transport at a horizontal distance. Thereby customers don’t need to buy other horizontal conveyor equipments.

The Z series bucket elevator composes of the following parts, such as conveying parts, driving device, upper device, middle casing, and lower device. Међу њима, the conveying parts include buckets and chains.

Bucket elevator components: 1~elevator body, 2~feeding port, 3~discharge port, 4~drive motor, 5~bucket, 6~cylinder, 7~driven sprocket, 8~drive chain, 9~guide wheel, 10~slider, 11~tensioning device, 15~studs.

How does a bucket conveyor work?

It is suitable for lifting items from a low place to a high place. Најпре, feed the material into the buckets through the hopper. Then the vertical conveyor automatically runs continuously and upwards. To put it simply, the two circular chains are full of elevator buckets. После тога, the motor drives the chain to rotate. So the bucket rotates with the chain. Коначно, the material is lifted and transported to the designated location for unloading. The buckets discharge materials by centrifugal force and gravity. So as to realize the vertical conveying.

When the Z elevator conveyor works, the gear motor drives the two sprockets to move synchronously through the bearings. So the two chains move synchronously on the closed track. When conveying the material to the feeder, it slides and falls into the horizontal forward buckets. Since the material is slipped into the elevator buckets, so the material will not be broken.

Додатно, the Z style bucket conveyor is usually closed. So it prevents dust from flying. Наравно, bucket elevator has inspection door. Према томе, customers can observe vertical conveyor operation at any time.

Bucket Elevator Conveyor Advantages & Карактеристике

The Z-type bucket elevator integrates the horizontal conveying and lifting of materials. Тако, one Z vertical conveyor can replace the traditional three conveyor equipments. Односно, the two horizontal conveyors + one vertical lift conveyor.

1. Прво, the conveying range is wide. This type of elevator conveyor does not have high requirements for the types and characteristics of materials. Z vertical conveyor can not only lift powdery and small granular materials, but also lift bulk materials. Good airtightness and less environmental pollution.

Наравно, the bucket conveyor has a plexiglass cover. So it is convenient to observe the condition. Истовремено, the large window door is convenient for maintenance.

2. Друго, there are a variety of shapes and structures for choice. Према томе, распоред је флексибилан. And vertical conveyor can save factory area. The conveying track is horizontal-vertical-horizontal transportation. So it can greatly reduce unnecessary space occupation.

In addition to Z conveyor, bucket conveyor can also be C shape and T-shaped. Штавише, both the feeding port and the discharging port can have multiple ports.

How to Select Bucket Elevator Conveyor?

When customizing the vertical conveyor, you need to inform the manufacturer of the specific application. Наравно, before you select the vertical conveyor, you should confirm which shape you need. Z style or C shape bucket elevator or other shapes? Додатно, if need multiple discharge ports or feeding ports, just tell us.

1. 1.Прво, Material Characteristics

It mainly include various parameters, such as bulk density, temperature, viscosity, итд. Штавише, different conveyed products, different elevator body & bucket materials. The outer casing of bucket conveyor can be carbon steel and stainless steel. Додатно, there are several kinds of elevator buckets materials, such as ABS plastic, угљен челик, СС304 нерђајући челик, SS316 stainless steel, итд.

So what materials to select? На пример, if your appliation is to convey food, it must to use the sanitary ABS or stainless steel buckets. Истовремено, the machine casing should be also stainless steel. And if you want to transport the high temperature products, it can’t to use the plastic elevator buckets. Додатно, when lifting the corrosive goods, it should use the SS304 or SS316 buckets.

2. Друго, How to calculate the volume / capacity of a bucket elevator?

Usually, the capacity of bucket conveyor is determined by several aspects, such as elevator conveyor size, bucket volume and conveying speed. Here is a simple calculation formula. Conveying volume per hour = (bucket volume * single row bucket number) * Т * 60 * 75%. (Међу њима, T is the number of times a single-row buckets run in one minute). Додатно, why is there 75%? That’s because, in the actual conveying process, it is difficult to achieve 100% conveying efficiency. Другим речима, the elevator buckets are difficult to fill.

На пример, the height of the vertical conveyor is 3.5 метара. The bucket volume is 6.5L. Додатно, the width of the 6.5L bucket is 223mm. The operating speed of the elevator conveyor is 10 м / мин. Then the number of buckets in a single row is 16pcs. And T=10/3.5≈2.86 times. Према томе, the conveying capacity of the bucket conveyor per hour = (6.5L*16)*2.86*60*75% = 13384.8L ≈ 13.38m³.

3. Треће, electric motor of elevator conveyor

Изнад свега, you can choose mount the electric motor on the top or bottom of bucket conveyor. Both are ok. Што је још важније, it must consider the explosion-proof property of the motor in some special occasions. Bucket elevator often conveys powdery materials, for instance flour. Према томе, in order to avoid dust explosions, it needs to use explosion-proof motor. Истовремено, during the design of the vertical conveyor, it is necessary to consider preventing the generation of static electricity.

Bucket Elevator Troubleshooting

During bucket conveyor application, there may be many kinds of problems. The following are common problems and solutions for elevator conveyor.

1. How to solve the problem of elevator buckets?

There are some reasons for the failure of the buckets.

1. (1) There are cracks on the buckets

2. We often use ABS plastic buckets for vertical conveyor. Although the ABS plastic bucket is very strong, it may be damaged. If there is a crack in the bucket, it needs to check carefully. Прво, see where the cracks appear. If there is a crack in the center of the bucket, this is likely to be caused by manual violent feeding. Or it may also be caused by hitting the elevator bucket. Под нормалним околностима, there will be no cracks in the center. Према томе, operators must be trained. So it can avoid damage to the bucket due to operating errors.

(2) High temperature and corrosive materials

The temperature resistance of the plastic bucket has a certain limit. As long as it is within the safe value range, there is no problem for bucket conveyor. Међутим, once the temperature is too high, the plastic bucket cannot withstand it. Eventually it will deform the elevator bucket.

Додатно, some customers do not know that the material will be corrosive during using the Z-type elevator conveyor. So long use will cause damage to the buckets. Према томе, we must not only choose the elevator buckets of the right material, but also use them correctly.

(3) Material proportion is relatively large

Some users also said that they use stainless steel buckets. But the buckets are still easily damaged. Later, we knew that the proportion of materials was relatively large. The specific gravity is as high as about 7. У овом случају, it needs to communicate with the manufacturer in advance.

When using bucket conveyor, it can choose larger models buckets. Because the total amount that a large-size buckets can bear is also relatively large.

2. How to solve the noise problem of Z type vertical conveyor?

Different noises, different solutions.

(1) Motor noise

The motor noise is normal. When the stator and the rotor rub against each other, there will be a harsh clashing sound. This is mostly caused by a faulty bearing. У ово вријеме, it needs to stop immediately. Then check whether the motor bearings are damaged.

Додатно, the motor bearings of elevator conveyor require maintenance. When the bearing is severely short of oil, some noise will occur. So you need to add new oil.

(2) Chain noise

The wear of the chain and sprocket will also cause noise. Too much chain tension, insufficient chain lubrication, and too large chain pitch will affect the use of the chain. Према томе, it needs proper lubrication at this time.

(3) The sound of falling materials

The materials in the elevator buckets are full. They fall into the bucket conveyor body during operation, causing some noise. У ово вријеме, it requires uniform feeding. Истовремено, avoid the conveying volume exceeding the load capacity of the vertical conveyor. In order to avoid damage to the machine.

If you encounter these noises, be sure to stop the elevator conveyor firstly. And then perform an inspection.

Bucket Conveyor Operation & Одржавање

Correct operation and maintenance are essential to the service life of the elveator conveyor.

1. Trial operation of Z-type vertical conveyor

After finishing bucket elevator installation, it should carry out a test run with an empty machine. Pay attention: it cannot be reversed. And there must be no bumps. Empty running is not less than 2 сати. Осим тога, there should be no overheating. The temperature rise of the motor does not exceed 30°C. After 2 hours of test operation, it can carry out the load test if everything is normal.

2. Start Z-type bucket elevator without load

Before shutdown each time, you should drain all materials in the buckets. Then stop the machine again. Штавише, don’t operate the elevator conveyor reversely. The chain derailment may occur because of the reverse. Solving the derailment is very troublesome.

3. Feed evenly

It is forbidden to increase the feeding amount suddenly. The feeding amount cannot exceed the conveying capacity of the bucket elevator. Иначе, it is easy to cause accumulation of materials at the bottom.

Напротив, if the feed is less, it will reach the rated feed of the equipment. So it will reduce the transportation capacity of the bucket conveyor.

4. How to clean the bucket conveyor?

(1) Прво, remove debris and dust on the surface of the vertical conveyor. Imediately afterwards, clean the bucket elevator with dish soap. Then clean it with clean water. Коначно, употреба 75% medical alcohol to clean the surface of the elevator conveyor.

(2) Друго, open the side prorection plate of the chain. Remove all elevator buckets correctly. The cleaning method for buckets is the same as above. Након чишћења, put it back into the buckets. And install the side panels.

(3) Remove the discharge port and other cover plates on the top of the elevator. Онда, clean it in the same way. Након чишћења, install the cover plates.

5. Lubricate the spare parts of elevator conveyor

(1) Open the cover of the tensioning device of vertical conveyor. Apply engine oil evenly on the screws and nuts of the tensioning mechanism. The guide rails and bearings need to be lubricated. Коначно, close the cover.

(2) Add solid lubricating oil to the bearing seat of the driving sprockets.

6. Replace the broken chains & elevator buckets timely

If find that the buckets are damaged during operation, stop the bucket conveyor for inspection in time. And replace with new elevator buckets. Иначе, continued operation will cause more buckets damage. Слично томе, it should check the condition of the chain at any time. Ако је оштећен, replace it in time.

Додатно, regularly check the tightening of the nuts on the machine body and other parts. Prevent the nut from loosening and affecting the normal operation of the bucket elevator.
