DETAILED DESCRIPTION

[0016] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0017] Please refer to Figures 1 to 2 The elastic sealing device at the top of the drying chamber in the embodiment comprises a top wall of a drying chamber 1, and the top wall of the drying chamber 1 is provided with a sealing structure.

[0018] The sealing structure comprises two rotating fixed plates 2 fixedly installed on the top of the top wall plate 1 of the drying chamber, springs 3 fixedly installed on the opposite side outer walls of the two rotating fixed plates 2, movable rotating rods 4 rotatably installed on the front side outer walls of the rotating fixed plates 2, L-shaped stainless steel plates 5 fixedly installed on the outer circumferential walls of the movable rotating rods 4, and two L-shaped stainless steel plates 5 respectively fixedly connected on the opposite side outer walls of the two L-shaped stainless steel plates 5.

[0019] The L-shaped stainless steel plates 5 are fixedly installed with high-temperature-resistant rubber plates 6 on the sides away from the top wall plate 1 of the drying chamber, and the L-shaped stainless steel plates 5 are movably connected on the top of the top wall plate 1 of the drying chamber on the sides away from the high-temperature-resistant rubber plates 6. The two L-shaped stainless steel plates 5 are both inclined towards the direction of the aerial conveying boom 7. The aerial conveying boom 7 is slidably connected in the drying chamber top gap 8 of the top wall plate 1 of the drying chamber. The aerial conveying boom 7 is slidably connected in the drying chamber top gap 8 and is of the same size. The aerial conveying boom 7 is slidably connected between the two high-temperature-resistant rubber plates 6. The rotating fixed plates 2 are trapezoidal. The distance between the opposite side outer walls of the two rotating fixed plates 2 is the same as the width of the drying chamber top gap 8.

[0020] In the embodiment, the movable rotating rod 4, the L-shaped stainless steel plate 5 and the high-temperature-resistant rubber plate 6 are connected into one body. The movable rotating rod 4 is installed on the rotating fixed plate 2 but can rotate. The two sides of the spring 3 are respectively fixed on the rotating fixed plate 2 and the L-shaped stainless steel plate 5.

[0021] The working principle of the above embodiment is as follows:

[0022] When the aerial conveying boom 7 is slidably connected between the two high-temperature-resistant rubber plates 6, the upper ends of the L-shaped stainless steel plates 5 and the high-temperature-resistant rubber plates 6 are extruded and then deviated outward. After the aerial conveying boom 7 passes through, the L-shaped stainless steel plates 5 and the high-temperature-resistant rubber plates 6 are restored to their original positions due to the pulling force of the spring 3. The two high-temperature-resistant rubber plates 6 are in close contact with each other, so that the top of the drying chamber remains in a sealed state.
