Analysis Of Inner Structure Of Hot Air Circulating Oven Equipment

- Oct 10, 2019-

I. characteristics of hot air circulation oven

1. Most hot air circulates in the hot air circulation oven, with high thermal efficiency and energy saving;

2. With the function of forced ventilation, the cabinet is equipped with adjustable air distributor to ensure uniform drying of materials;

3. Low noise and smooth operation;

4, temperature control, easy installation and maintenance.


Ii. Production details:

1. Structure design of hot air circulation oven:

Two doors, two cars, conventional design, each door longitudinal arrangement of a drying car, each car 24 plates, a total of 48 plates.SUS304 stainless steel is pasted around the box and fully welded. The hot air circulation oven is compact and strong.

2. Material requirements of hot air circulation oven:

Inner wall stainless steel SUS304, outer wall Q235 spray anti - rust paint.

3. Main requirements of hot air circulation oven:

The whole frame structure, the outer surface of the box body is smooth, smooth, consistent in color, the overall appearance, no obvious concave and convex phenomenon.

4. Requirements for inner body of hot air circulation oven:

The inner cavity is fully welded and the round corner is in transition, so that there is no channeling between the hot air circulation oven and the outside world in the working state. The hot air circulation oven is easy to clean and there is no water seepage in the insulation layer.

5. Requirements for car drying and pan drying:

Drying car material SUS304 stainless steel, drying car column with stainless steel square pipe, the beam for stainless steel Angle steel, argon arc welding, bottom support, column strengthening.Each dryer is equipped with 2 directional wheels and 2 directional wheels. The material is stainless steel SUS304.Drying plate thickness 0.8mm, material SUS304.

6. Entry and exit of the drying truck:

The use of concave track, channel steel support is strengthened, meet the requirements of load bearing, and make the drying car access to the hot air circulation oven convenient.

7. Hot air cleaning requirements:

The hot air circulation oven is equipped with middle school filter in the inlet air and sub-high efficiency filter in the outlet air. The fresh air is up to 300,000 grade, which makes the clean degree of the circulating air in the hot air circulation oven and the clean degree of the air returning from the outlet air.

8. Heating form of hot air circulation oven:

Electric heating.The electric heating power is 15KW. Each electric heating tube is arranged in a parallel way of 1KW to increase the heat dissipation area.

9. Fan selection:

Adopt low noise and high temperature axial flow fan, impeller and vortex shell are made of stainless steel, impeller material is SUS304.The left and right sides of the box are equipped with adjustable air distribution devices.This forced ventilation makes the air volume and wind speed even and makes the material dry quickly and evenly.

10. Sealing requirements of hot air circulation oven:

The door and the box body adopt the high temperature resistant non-toxic high temperature resistant silicone rubber sealing ring, the sealing performance is good.

11. Insulation requirements:

The insulation layer of the hot air circulation oven is made of super fine glass wool with thickness up to 90mm.

12. Control requirements:

The control system of the hot air circulation oven adopts the touch type (film switch) controller, which is set in the upper right corner of the cabinet.

13. Wind-regulating louver design:

In view of the common problem that hot air circulation oven is difficult to clean, we have changed the fixed connection of some manufacturers, and our company has adopted the open-door design.
