Detailed :

Structure design: the furnace is made of stainless steel plate, surrounded by heating hot air circulation chamber, hot air flows in the furnace, greatly improving the temperature uniformity. Because of the mixing of hot air, the convection heat sharing of atmosphere in the furnace are strengthened.

The furnace the furnace frame are designed separately. The furnace is placed on the load-bearing roller at the bottom of the furnace frame, the front rear can slide freely. When the furnace is heated, it can extend freely along the length direction.

In order to prevent the leakage of hot gas in the furnace, a total of 2 layers of seals are designed at the furnace door inside to outside. The inner layer adopts ceramic fiber rope sealing structure, the outer layer adopts silicone rubber sealing ring. In order to prolong its service life, stainless steel cooling water jacket is designed at the furnace mouth seal for cooling. The door lock adopts multi-point handwheel rotation locking mechanism, which can lock the door around evenly at the same time. In addition, the fixing device of furnace door is installed on the end face of furnace, the movable double hinge mechanism is adopted, which can move with the free extension of furnace, the sealing effect is good.

An exhaust chimney is designed on the top of the equipment to discharge a large amount of waste gas smoke generated in the heating process. The discharge flow can be controlled by adjusting the handle of the damper.

control system design

The control system is integrated in the furnace body. The intelligent program temperature controller is selected, the temperature curve is adjusted by setting automatic control. The linear combination is used to control the object. The temperature controller receives the signal detected by thermocouple controls the power module.

Fan position design

The fan is located at the rear of the furnace. The air is blown through the heating elements through the volute the air ducts on both sides. After the atmosphere is heated, it enters the furnace horizontally to heat the workpiece evenly, then it is sucked into the circulating fan through the suction outlet at the rear to fully circulate stir.

Design of diversion device

If the volute is removed, the fan performance will be reduced by more than 50%. The hot air box furnace adopts double circulation mode, the fan is located at the rear of the furnace body, there are two circulation air ducts on both sides, the rear volute has two-way air outlet.

In the hot air chamber, due to the limited space, the expansion section of the volute is short, the outlet area is large, the air pressure loss is large. In the design of volute, the shape of guide vane should be reasonable, the number of guide vane should be 4-8, the installation angle of guide vane should be determined according to the impeller shape flow rate. The width of volute should be designed without touching the impeller.
