Високотемпературна метална тунелна пещ с непрекъснат конвейер

Tunnel oven is a kind of continuous continuous furnace heat treatment. It also has other names, such as tunnel furnace, industrial conveyor oven, drying conveyor oven, high temperature drying line, и т.н.. The mesh belt furnace has several heating methods, като: radiation, hot air circulation and radiation + hot air circulation, и т.н.. Първо, manually place the workpiece on the conveyor mesh belt. Тогава, after drying, the material is discharged. Because it has many advantages, it is of great significance for mass drying. The mesh belt furnace adopts a sealed structure, and the appearance is beautiful. В допълнение, the dying oven equipment is easy to disassemble and maintain.

The main application of mesh belt furnace for water vapor, curing and drying of hardware accessories and metal parts. Industrial tunnel oven has also application for the food industry. The temperature that the continuous mesh belt furnace can adapt to high temperature up to about 200℃~300℃. По същото време, it also can use the continuous furnace to dry the materials with certain humidity or particle size such as iron ore, titanium ore, quartz sand and other minerals.

Например, the temperature control of the conveyor furnace supplied to one customer adopts “thermostat + SSR solid state relay + thermocouple control“.

1. when you start the machine, if the temperature is lower than the set temperature, the SSR solid state relay is closed. And then the heating element starts heating.

2. If the temperature is higher than the set temperature, the SSR solid state relay is open. And then the heating element stop heating.

1. Turn on:

Turn on the main power of the conveyor mesh belt furnace → turn on the power switch → turn on the air flow → set the temperature → bake the workpieces.

Първо, turn on the main power switch of the distribution box and the fan. По това време, индикаторът за захранване свети. Check the ventilation of the exhaust fan. If it operates normally, it shows that the continuous furnace can be used. After all preparations are ready, it can put the products into the furnace. Then connect and turn on the power. When the red indicator light is on, it means that the conveyor furnace has been heated. When the temperature reaches the controlled temperature, the red light is off and the green light is on. По това време, it indicates that the constant temperature has begun. In order to prevent the temperature control from failing, it must look after it.

When placing the products, please note that the arrangement cannot be too dense. Don’t place any product on the heat sink, so as not to affect the upward flow of hot air. It is forbidden to bake flammable, explosive, volatile and corrosive items.

Pay attention to the safe use of electricity. According to the power consumption of the tunnel furnace, install a switch with sufficient capacity. По същото време, select enough power supply wires, and there should be a good grounding wire.

In order to avoid vibration and corrosion, it needs place the tunnel mesh belt furnace indoor. And there should be dry. When in use, the temperature should not exceed the maximum operating temperature of the continuous furnace heat treatment.

1. Be familiar with the location and function of the equipment components before the test machine. So it can operate the tunnel mesh belt furnace safely.

2. It needs turn off the main power supply during maintenance. За да избегнете опасност.

3. Do not place any objects on the top of the tunnel continuous furnace cover, so as not to affect the mechanical performance.

4. Turn off the heating switch after using the tunnel conveyor furnace. Let the machine continue to cool naturally in order to extend the service life of the heating element. After the temperature drops to about 100°C, turn off the power again.

5. It needs clean the inside of industrial conveyor oven at least once a week. Thus it can work well. And this will maintain good drying quality.

6. В допълнение, it must clean the electrical switchboard once a month. And check whether the fixing screws are loose.

Other maintenaces of conveyor furnace are as follows:

7. Check whether the grounding wire and temperature sensing wire are off.

8. Confirm whether the connection between the exhaust port of the control box and the outdoor is firm, so as to prevent the dust in the control box from polluting the clean room. It will affect the normal temperature in the control box and cause premature damage to electrical parts.

9. When transporting and installing, please be careful not to collide, so as not to affect the appearance and function of the conveyor furnace.

10. When repairing, please cut off the power supply. Moreover only professionals can operate it. Do not open the control box at will in order to avoid the danger of electric shock.

11. It is strictly forbidden to get rain or direct sunlight. По същото време, it must clean the ventilation holes to allow air circulation.

12. Regularly check the exhaust pipes of the continuous furnace. Освен това, exhaust the exhaust gas to the outdoors.

13. The inside and outside of the tunnel mesh belt furnace should be clean. If it is shut down for a long time, please cut off the power. По същото време, it needs pack the conveyor furnace well.
