The two handles 6 are respectively disposed at the upper and lower positions on one side of the door panel 2, opposite to the mounting side of the eccentric hinge 5. The inner and outer handles of the handle 6 are in a parallel relationship.

[0025] The entrance 3 of the dry spray tank is an opening on the stainless steel wall panel of the dry spray tank. As Figure 2 and Figure 3 shown in the cross-sectional view, the door frame 1 is welded at the entrance 3 of the dry spray tank. The door frame 1 is assembled into one body by welding the four stainless steel channel-shaped plates end to end. Grooves 11 are provided on the top surface, bottom surface, left side surface and right side surface of the door frame 1. The grooves 11 on the top surface and bottom surface of the door frame 1 are as long as the top surface or bottom surface of the door frame. The grooves 11 on the left side surface and right side surface of the door frame 1 are as long as the left side surface or right side surface of the door frame.

[0026] The seal 4 is located within the groove 11. The width of the seal 4 is slightly larger than the width of the groove 11. In a specific embodiment, the width of the groove is 18 mm, and the width of the seal 4 can be 20 mm. The seal 4 is in interference fit with the groove 11, and the seal 4 is stuck in the groove 11.

[0027] The seal 4 includes an integrally formed rectangular portion and an arc-shaped convex portion. The top of the arc-shaped convex portion protrudes slightly from the groove 11. The top of the arc-shaped convex portion protrudes 1 - 2 mm from the groove 11. There is a through hole between the arc-shaped convex portion and the rectangular portion.

[0028] The seal can be made of rubber or heat-resistant silica gel with slight elasticity.

[0029] The door panel 2 includes a stainless steel panel 21, a stainless steel inner plate 22 and a U-shaped plate 7. The U-shaped plate 7 is disposed between the panel 21 and the inner plate 22. Two U-shaped plates 7 are disposed up and down between the panel 21 and the inner plate 22. Each U-shaped plate 7 is disposed at the position of the handle 6. The U-shaped plate 7 is used to increase the strength of the door panel 2. A round hole for the rotation shaft 61 of the handle 6 to pass through is reserved on the U-shaped plate 7. The rotation shaft 61 is in clearance fit with the round hole.

[0030] Each U-shaped plate 7 is installed horizontally, extending from the left side of the door panel 2 to the right side of the door panel 2. The U-shaped plate 7 is spot-welded on the surface of the panel 21 facing the inner plate 22. The length of the U-shaped plate 7 is slightly shorter than the width of the door panel 2.

[0031] After installing the blind rivet nut 9 on the U-shaped plate 7, weld one side of the U-shaped plate 7 to the stainless steel inner plate 22 as a whole, weld the other side of the U-shaped plate 7 to the stainless steel panel 21 as an integral body, and then weld the panel 21 and the end of the inner plate 22 together to form the door panel 2.
