The pulp is filtered at the outlet of the equipment, but the filter structure is easily clogged by the accumulated residue and needs to be cleaned regularly. However, manual cleaning is inefficient and requires disassembling the pulping equipment to remove or clean the filter structure. This results in long maintenance time, long equipment downtime, and consequently reduced production efficiency. Utility Model Content

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figures 1 to 6 As shown, this utility model can be implemented through the following embodiments: A papermaking pulping device includes a pulping cylinder 1, a motor 2 installed at the top of the pulping cylinder 1, the motor 2 connected to a stirring rod 21, a pulp outlet pipe 11 provided at the bottom of the pulping cylinder 1, a filter chamber 3 installed below the pulp outlet pipe 11, a slot 33 opened on the outer wall of the filter chamber 3, a filter plate 31 slidably installed in the slot 33, a filter frame 311 provided outside the filter plate 31, an installation groove 32 opened on the side wall of the filter chamber 3, a cleaning plate 4 installed in the installation groove 32, a storage box 5 connected to the filter chamber 3, a blocking block 6 provided between the storage box 5 and the filter chamber 3, and a hydraulic cylinder 61 connected to the blocking block 6.

[0024] A slot 33 is provided on the side wall of the filter chamber 3, through which the filter plate 31 is installed, facilitating the disassembly and removal of the filter plate 31; the filter frame 311 is used to mate with the slot 33, so that the filter plate 31 is installed in the filter chamber 3; the cleaning plate 4 is installed in the filter chamber 3, so as not to affect the filtration of pulp by the filter plate 31 during filtration, and to clean the debris on the filter plate 31 during cleaning; the blocking block 6 is used to block the channel between the storage tank 5 and the filter chamber 3 to prevent pulp from flowing into the storage tank 5, and the hydraulic cylinder 61 is used to control the movement of the blocking block 6.

[0025] like Figure 1 and Figure 2As shown, lead screw 1 41 and lead screw 2 42 are connected to both sides of the cleaning plate 4. Lead screw 1 41 is connected to motor 2 43, and lead screw 1 41 and lead screw 2 42 are connected by a pulley 44. Motor 2 43 transmits power to lead screw 1 41, which drives lead screw 2 42 to rotate synchronously through pulley 44, thereby realizing the movement of the cleaning plate 4. This allows the cleaning plate 4 to perform the cleaning function, removing debris from the filter plate 31 and preventing clogging.

[0026] like Figure 1 and Figure 4 As shown, a sealing plate 312 is provided on the filter frame 311, and a sealing groove 331 is opened on the slot 33. A sealing strip 7 corresponding to the sealing groove 331 is installed on the sealing plate 312. The sealing plate 312 and the sealing groove 331 cooperate to increase the contact area between the filter frame 311 and the slot 33 and increase the bending, thereby improving the sealing performance; the installation of the sealing strip 7 is used to fill the gaps and improve the sealing performance at the bending points.

[0027] like Figure 1 , Figure 4 and Figure 5 As shown, the filter frame 311 has protrusions 311a on both sides, and the cleaning plate 4 has striking blocks 45 on both sides. The striking blocks 45 are connected to striking springs 451. The protrusions 311a are used to lift the striking blocks 45, so that the striking blocks 45 are away from the filter frame 311. When the striking blocks 45 lose contact with the protrusions 311a, the striking blocks 45 are reset under the push of the striking springs 451, knocking the filter plate 31, causing the debris to fall off the filter plate 31, thus improving the cleaning efficiency.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, fixing parts 8 are provided on both sides of the slot 33. Limiting blocks 81 are installed in the fixing parts 8. Through holes 82 are opened between the fixing parts 8 and the slot 33. Limiting grooves 311b are opened on the filter frame 311. The limiting blocks 81 pass through the through holes 82 and are inserted into the limiting grooves 311b to fix the filter chamber 3 and the filter plate 31 together, restrict the displacement of the filter plate 31, and prevent the filter plate 31 from falling out of the slot 33 due to vibration during the pulping process.

[0029] like Figure 1 and Figure 6 As shown, the rear end of the limiting block 81 is provided with a pressing surface 811, and the top of the fixing part 8 is inserted with a pressing block 9, which is in contact with the pressing surface 811. The pressing block 9 and the pressing surface 811 are in contact, so that after the pressing block 9 is inserted into the fixing part 8, it presses and pushes the limiting block 81 to move, so that the limiting block 81 passes through the through hole 82 and is inserted into the limiting groove 311b.

[0030] like Figure 1 and Figure 6As shown, the limiting block 81 is provided with a reset part 812 on both sides, and a reset spring 813 is installed between the reset part 812 and the fixing part 8. After the pressing block 9 is removed, the limiting block 81 is reset by the cooperation of the reset part 812 and the reset spring 813, releasing the limiting block 81 from the filter plate 31, making it easy to remove.

[0031] like Figure 1 , Figure 3 and Figure 6 As shown, the fixing part 8 is provided with a slot 83, and the squeezing block 9 is provided with a hook 91. The slot 83 and the hook 91 cooperate to restrict the displacement of the squeezing block 9 in the fixing part 8, and prevent the squeezing block 9 from loosening due to the vibration generated during the operation of the equipment, which would cause the limiting block 81 to reset, and thus cause the filter plate 31 to loosen and fail to perform the filtering function.

[0032] like Figure 1 and Figure 6 As shown, the compression block 9 is provided with a rod 92, and the fixing part 8 is provided with a hole 84, and a push spring 10 is provided in the hole 84. The rod 92 and the hole 84 cooperate to guide the movement of the compression block 9, so that the compression block 9 can slide up and down after being released from the locking position, making it easy for the user to remove the compression block 9; the push spring 10 is used to push the compression block 9 through the push slot 33, so that the compression block 9 pops out after being released from the locking position 8, making it easy for the user to take out the compression block 9.

[0033] The working principle of this utility model is as follows: Motor 12 is started, which drives the stirring rod 21 to stir the pulp. After stirring is completed, the pulp outlet pipe 11 is opened to send the pulp into the filter chamber 3. After the pulp passes through the filter chamber 3, the pulp is filtered to remove the debris and finally flows out of the equipment. Hydraulic cylinder 61 is started to move the blockage block 6. Then, motor 243 is started, which drives the cleaning plate 4 to move through the rotation of lead screw 141 and lead screw 242. The cleaning plate 4 collects and scrapes up the debris and finally pushes it into the storage box 5.

[0034] Move the hook 91 on the squeezing block 9 so that the squeezing block 9 pops out under the push of the push spring 10. Then the limit block 81 is reset under the push of the reset spring 813, releasing the jamming of the filter chamber 3 on the filter plate 31, and taking out and replacing the filter plate 31.

[0035] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0036] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
