250℃ augstas temperatūras infrasarkano staru konveijera krāsns krāsns

Apraksts

Šī ir rullīšu konveijera krāsns mūsu klientam Francijā. Tā ir augstas temperatūras infrasarkanā konveijera krāsns plastmasas fragmentu pagatavošanai. Darba temperatūra ir 250 ℃ un maksimālā temp. ir 300 ℃. Klients ievietoja plastmasas fragmentus tērauda paplātē, un pēc tam ielieciet paplāti uz rullīšu konveijera termiskai apstrādei. Augstas temperatūras dēļ, mēs izmantojam 304 nerūsējošā tērauda veltņi. Papildus, šajā nepārtrauktā rūpnieciskā tuneļa krāsnī ietilpst trīs daļas. Proti, ieejas konveijers, izejas konveijers un vidējā tuneļa krāsns.

Žāvēšanas krāsns pieņem karstā gaisa cirkulāciju + tālā infrasarkanā sildīšanas metode. Rūpnieciskā tuneļa krāsnī temperatūra ir vienāda. Bez tam temperatūra ātri paaugstinās. Infrasarkano staru konveijera krāsns ir plaši pielietojama daudzās nozarēs, piemēram, aparatūras metāla detaļas, plastmasas, sietspiede, powder coating, PCB or electronics, utt. The conveyor furnace can play the role of drying and curing. Papildus, conveyor oven can also suitable for food industry, such as pizza, cepumi, bread and seafood. It can play a role in drying, dehydrating and sterilizing.

How does infrared conveyor oven work?

The industrial tunnel oven is a tunnel type machine that drying products through heat conduction, convection, and radiation. There is a continuous conveyor system in the tunnel. It will generate the relative movement between the product and the heating element through the conveyor chain, roller or mesh belt. So as to complete the work of uniform baking and conveying.

There are several types of heating elements, such as infrared heating tubes, stainless steel heating tubes and so on. Infrared rays can reach every corner of the furnace. Then the temperature rises evenly, transferring energy to the object. Tajā pašā laikā, the wind motor drives the blades to generate hot air circulation. Tāpēc, augšējā un apakšējā temperatūra krāsnī ir vienmērīgāka. Lai nodrošinātu krāsns izstrādājumu kvalitāti. Papildus, siltumizolācijas materiālam ir laba siltumizolācijas veiktspēja un tas var efektīvi novērst siltuma zudumus.

Rūpnieciskā tuneļa krāsns tehniskie dati

No kā izgatavota tuneļa krāsns? Konveijera krāsns galvenokārt sastāv no vairākām daļām, piemēram, konveijers, izolācija & apsildes sistēma, vadības sistēma un drošības aizsardzības sistēma.

The following are the technical specifications of the roller conveyor tunnel furnace for our French customer.

Total length is 4.5m and conveying surface width is 1.4m. Turklāt, the working temperature is 250℃ for 30 minūtes.

1. Pirmkārt, the oven shell uses 1.5 thickness galvanized sheet.

2. Otrkārt, the inner liner uses 1.5 thickness 304 stainless steel mirror panels. And weld well all around in order to prevent high temperature cracking.

3. Treškārt, use two layers of 40mm thickness aluminum silicate as insulation material.

4. Ceturtkārt, Taiwan brand high-quality infrared heating tube: 17pcs, and each power is 1.5KW. So the power of industrial tunnel oven is about 25KW.

5. Piektkārt, 750W Wind-driving motor, with 12-inch pig-cage fan blades.

6. Install the air baffles on the left and right sides. When infrared conveyor oven heats up, close them manually. Then the tunnel oven starts to work. Papildus, there are 2 air outlets on the top.

7. Sestkārt, control electric box:

Chint brand. With leakage protection air switch, start switch, indicator light. With digital display thermometer, Chint AC contactor, independent control box for drying furnace.

The temperature range is from room temperature to 300℃. Timing control. Alarm function. Set automatic temperature control. And use the RKC thermostat.

8. Papildus, there is cylinders to lift the oven cover for maintenance.

10. Appearance color: powder spraying, and color is deep-gray as request.

11. The side guide rails of the roller conveyor are bent into a C shape with a 3mm thickness cold rolled plate.

12. The support stands use 40*80 2.0mm thick square steel tube. Turklāt, they are with M14 adjusting foot (height-adjustable from 1200 to 1300mm).

13. Turklāt, mēs izmantojam 304 nerūsējošā tērauda veltņi. Double-row gears. The roller thickness is 2mm. Diameter is 60mm. And roller spacing is 150mm.

14. Visbeidzot, roller conveyor uses the AQL brand 750W motor. The speed ratio is 1:60. The speed is 1~7m/min adjustable. Equipped with Delta 750W VFD frequency converter.

Turklāt, konveijers var pārvietoties abos virzienos.

Laipna piezīme: ir pieejami arī citi elektronisko vadības ierīču zīmoli, piemēram, fig, Šneiders vai Siemens. Turklāt, termostata un konveijera motora zīmolu var arī pielāgot.

Rūpnieciskā tuneļa krāsns raksturojums

1. The heating time of infrared conveyor oven is fast. Turklāt, the temperature is stable and accurate. Due to the use of hot air circulation and infrared heating, the temperature uniformity is good. So it is conducive to product heat treatment.

2. Using intelligent temperature controller PID automatic calculation. Un, cooperate with SSR solid state relay. Tāpēc, it can control the accuracy of the temperature accurately.

3. Due to the thermal insulation cotton, high temperature resistant sealing strip and entrance & exit barrier plates, the heat insulation effect is good. Tajā pašā laikā, the outer shell temperature of industrial tunnel oven is low. So there has little effect on the indoor environment temperature.

4. Under normal circumstances, the upper cover of the infrared conveyor oven is relatively heavy. Tāpēc, we add cylinder or an electric lifting rod onto conveyorfurnace. This facilitates maintenance and replacement of the heating tube.

5. The electrical control is safe and reliable, with dual over-temperature protection functions. At the same time it’s with an emergency button.
