[0019] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0020] Please refer to Figures 1-3 In the embodiment of the present application, a paper pulp screening device comprises a tank body 1, a top of the tank body 1 is detachably connected with an upper cover 2, a manual driving mechanism is installed between an outer wall of the tank body 1 and a top of the upper cover 2, and a limiting mechanism is formed between a bottom end edge of the upper cover 2 and a top end edge of the tank body 1.
[0021] In the embodiment, in the process of paper pulp production, the pressure screen is used to screen the paper pulp, and the impurities and fiber bundles contained in the paper pulp are filtered out. After use, the inner wall of the tank body 1 needs to be cleaned regularly to avoid the effect of blockage. At this time, the bolts and nuts that lock the tank body 1 and the upper cover 2 are loosened and removed. Then the manual driving mechanism is rotated. The manual driving mechanism first drives the upper cover 2 to move upward. After the upper cover 2 is separated from the top of the tank body 1, a pushing force is applied to the upper cover 2. The upper cover 2 is rotated and dislocated from the top of the tank body 1. At this time, the tank body 1 can be opened, and the residual paper pulp in the tank body 1 can be cleaned.
[0022] Please refer to Figure 2 and Figure 3 The limiting mechanism comprises a limiting column 16 fixedly connected to a top edge protruding part of the tank body 1. A limiting groove 15 in open structure is formed in a bottom edge protruding part of the upper cover 2 and engaged with an outer wall of the limiting column 16.
[0023] In the embodiment, after cleaning, the upper cover 2 is reset to the top of the tank body 1. The upper cover 2 is pushed in the opposite direction. When the upper cover 2 is reset and rotated, the upper cover 2 drives the limiting groove 15 to engage with the outer wall of the limiting column 16 during the rotation process. At this time, the upper cover 2 cannot be rotated and is located directly above the tank body 1. Then the manual driving mechanism is rotated in the opposite direction. The manual driving mechanism drives the upper cover 2 to move downward and press the top of the tank body 1.
[0024] Please refer to Figure 1 The outer wall of the tank body 1 is fixedly connected with a first fixed plate 8, and the outer wall of the tank body 1 and located above the first fixed plate 8 is fixedly connected with a second fixed plate 9.
[0025] In the embodiment, the first fixed plate 8 is used to provide rotating support for the stud 10, and the second fixed plate 9 and the sliding groove inside the second fixed plate 9 are used to provide up-down sliding support for the lifting column 11.
[0026] Please pay attention to Figure 1 With Figure 2 The manual driving mechanism comprises the stud 10 which is rotatably connected to the top of the first fixed plate 8 and penetrates through the upper part of the stud 10, the sliding groove which is formed in the inner wall of the second fixed plate 9 and the lifting column 11 which is slidably connected to the inner wall of the sliding groove and is threadedly connected to the outer wall of the stud 10, and the movable ring 12 which is movably connected to the outer wall of the stud 10 and is located above the lifting column 11, the connecting plate 13 which is integrally formed on the outer periphery of the movable ring 12, the fixed column 7 which is fixedly connected to the top of the upper cover 2 and is fixedly connected to the end of the connecting plate 13, and the hand wheel 14 which is fixedly installed on the top of the stud 10.
[0027] In the embodiment, first, the hand wheel 14 is rotated to drive the stud 10 to rotate, at this time, the lifting column 11 moves up and down under the action of the threads in the inner wall of the lifting column 11, and the sliding groove effectively limits the outer wall of the lifting column 11, so that the lifting column 11 can only move up and down, until the lifting column 11 which moves upward contacts the bottom end of the movable ring 12, at this time, the movable ring 12 moves upward under the action of the lifting column 11, at this time, the movable ring 12 drives the connecting plate 13 and the fixed column 7 to move upward synchronously, the fixed column 7 which moves upward drives the upper cover 2 to move upward, when the upper cover 2 does not contact the top of the tank body 1, the upper cover 2 is further rotated, the upper cover 2 drives the movable ring 12 to rotate on the outer periphery of the stud 10, so that the upper cover 2 is dislocated with the tank body 1 after being rotated.
[0028] Please pay attention to Figure 1 The outer wall of the tank body 1 is respectively provided with the feeding pipe 3, the good slurry pipe 4, the thick slurry pipe 5 and the exhaust pipe 6 from bottom to top.
