Product introduction of trolley hot air circulation drying furnace

Trolley-type hot air circulation drying furnace is mainly used for uniform temperature drying of various processed parts. The electric furnace structure consists of furnace body, trolley, heating device, control system and other parts.

   The frame of the furnace shell is welded with profiled steel. The inner and outer walls are made of cold-rolled steel plates with a small thermal deformation coefficient. The inner lining is made of aluminosilicate refractory fiber needle punched cotton as heat insulation and insulation material, which reduces the temperature rise of the furnace wall.

The furnace door and shell are also welded with steel as the frame, and the outer wall is also made of cold-rolled steel plate, and the inner lining is also made of aluminosilicate refractory fiber needle-punched cotton as heat insulation and insulation material.

   The trolley is welded by section steel and equipped with a wheel at the bottom for flexible walking. The entire trolley can be pushed into the furnace body.

   The rubber asbestos packing is embedded around the furnace mouth. After the furnace door is closed, it is in close contact with the rubber asbestos packing at the furnace mouth to ensure no heat emission.

   The heating element adopts strip-shaped electric heating elements, which are respectively arranged on both sides of the furnace. The material is alloy and has a long service life.

耐热钢制作成离心式风叶。 In order to ensure the stability and uniformity of the furnace, the electric furnace is equipped with a ventilator device and a wind guide system. The ventilator device is placed on the top of the furnace body. The fan is made of 1Cr18Ni9Ti heat-resistant steel into a centrifugal air blade. The wind deflector system consists of a wind deflector and a wind deflector. The wind deflector is installed on the top of the furnace and has an air deflector. When the fan is turned on, the wind is thrown from the fan, blown evenly to the heating elements on both sides of the furnace through the air guide groove, blown into the furnace through the air guide opening at the lower part of the windshield, and then sucked into the fan through the air guide opening at the lower part of the fan. Then throw it out ..., in this reciprocating cycle, the heat generated by the heater is brought into the furnace, so that the workpiece is evenly heated.

   过零触发可控硅,智能表控温。 Temperature control system adopts PID zero-crossing triggering thyristor and intelligent meter to control temperature. In addition, the multi-point automatic recorder of Shanghai Dahua Instrument Factory is used to control the temperature and the over-temperature alarm to ensure that the workpiece is not over-temperature.

   Each mechanical transmission part of the electric furnace adopts chain control, that is, the fan device and the power supply of the heating element are automatically cut off after the furnace door is opened. After the furnace door is closed in place, the power of the fan device and heating element can be switched on to prevent malfunction and accidents due to misoperation.
