Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figures 1 to 6 This embodiment discloses a pulping device, including a tank 400, with a top cover 100 installed on the top of the tank 400. The top cover 100 includes a first cover plate 200 and a second cover plate 300. The first cover plate 200 is fixedly connected to the tank 400 by fasteners 250. The first cover plate 200 and the second cover plate 300 are connected by a hinge 500, so that the second cover plate 300 can be opened and closed at an opening on the top of the tank 400. A motor 410 is installed on the first cover plate 200. The motor 410 is connected to a support shaft 411 that extends into the tank 400. A stirring blade 412 is fixedly connected to the support shaft 411. The motor 410 can drive the stirring blade 412 to rotate, thereby stirring the material in the tank 400.

[0024] The second cover plate 300 has a first abutment portion 310 at one end facing the first cover plate 200. The first abutment portion 310 and the first cover plate 200 are provided with a first sealing element 232, which is made of rubber. This enhances the sealing performance at the joint where the first cover plate 200 and the second cover plate 300 are hinged.

[0025] Specifically, the first cover plate 200 has an inclined first contact surface 210 on the side facing the second cover plate 300, the second cover plate 300 has a first abutting surface 311 that abuts against the first contact surface 210, and the first cover plate 200 has a third contact surface 230 on the side facing the second cover plate 300. The extension direction of the third contact surface 230 is opposite to that of the first contact surface 210. Both the first contact surface 210 and the first abutting surface 311 are arc-shaped structures and are inclined towards the side where the first cover plate 200 is located. The third contact surface 230 and the third abutting surface 313 extend towards the side where the second cover plate 300 is located, thereby forming a horizontally arranged V-shaped structure on the side of the first cover plate 200 facing the second cover plate 300. The end of the second cover plate 300 facing the first cover plate 200 is embedded in the V-shaped structure. The bending of the V-shaped structure can enhance the sealing performance between the first cover plate 200 and the second cover plate 300.

[0026] The second cover plate 300 is provided with a third abutting surface 313 that abuts against the third contact surface 230. The third contact surface 230 is provided with a first groove 231, and the first sealing member 232 is embedded in the first groove 231. The third abutting surface 313 is provided with a first limiting groove 315 that covers the first groove 231. When the third abutting surface 313 contacts the third contact surface 230, the first groove 231 and the first limiting groove 315 together compress the first sealing member 232, thereby shaping the first sealing member 232 to fill the gap between the first groove 231 and the first limiting groove 315, thus enhancing the sealing performance.

[0027] A second contact surface 220 is provided between the first contact surface 210 and the third contact surface 230. The second cover plate 300 is provided with a second abutting surface 312 that abuts against the second contact surface 220. A second groove 240 is formed between the first contact surface 210 and the second contact surface 220. A second sealing element 241 is embedded in the second groove 240. The second sealing element 241 is made of rubber. A protrusion 314 is formed between the first abutting surface 311 and the second abutting surface 312. The protrusion 314 abuts against and squeezes the second sealing element 241, causing the second sealing element 241 to deform and thereby enhance the sealing performance.

[0028] The second cover plate 300 has a second abutment portion 320 at one end facing the edge of the tank body 400, which contacts the tank body 400. A third sealing element 425, made of rubber, is provided between the second abutment portion 320 and the tank body 400. This increases the sealing performance between the second cover plate 300 and the tank body 400.

[0029] Specifically, the opening of the tank body 400 is provided with an abutment groove 420 corresponding to the position of the second cover plate 300. The second abutment part 320 is embedded in the abutment groove 420. The abutment groove 420 includes a fourth contact surface 421 extending in the vertical direction and a fifth contact surface 422 and a sixth contact surface 423 extending in the horizontal direction. The fifth contact surface 422 and the sixth contact surface 423 are both inclined and in opposite directions, thus forming a maze-like structure to increase the sealing performance.

[0030] The second abutment portion 320 includes a fourth abutment surface 321 that contacts the fourth contact surface 421, a fifth abutment surface 322 that contacts the fifth contact surface 422, and a sixth abutment surface 323 that contacts the sixth contact surface 423. A third groove 424 is provided at the connection between the fourth contact surface 421 and the fifth contact surface 422. A third sealing member 425 is embedded in the third groove 424. A second limiting groove 324 is provided at the connection between the fourth abutment surface 321 and the fifth abutment surface 322, and the second limiting groove 324 covers the third groove 424. The second limiting groove 324 and the third groove 424 together compress the third sealing member 425, thereby increasing the sealing performance between the second cover plate 300 and the tank body 400.

[0031] The edge of the tank body 400 is provided with a fourth groove 430, and a fourth seal 431 is embedded in the fourth groove 430. The fourth seal 431 is made of rubber. The first cover plate 200 and the second cover plate 300 in the closed state together cover the fourth groove 430 and squeeze the fourth seal 431, thereby increasing the sealing performance between the tank body 400 and the top cover 100.

[0032] The second cover plate 300 is also provided with a sealing part 330 located outside the tank body 400 and extending downward to partially cover the side wall of the tank body 400. An elastic layer 331 is provided on the side of the sealing part 330 facing the side wall of the tank body 400. The elastic layer 331 is made of rubber. When the second cover plate 300 is closed, the elastic layer 331 is placed between the sealing part 330 and the side wall of the tank body 400. It is squeezed by the side wall of the tank body 400 and the sealing part 330, thereby further increasing the sealing performance between the second cover plate 300 and the tank body 400.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
