[0002] A closed pulp filter is a filtering device commonly used in the pulp processing process. Its main function is to filter out impurities, particles and other substances in the pulp to improve the quality of paper. A closed pulp filter usually consists of a filter box, a filter screen, a feed pipe and a discharge pipe. Since impurities will be retained on the surface of the filter screen when the filter screen is working, it is necessary to perform a slag removal and transfer operation on the filter screen.

The installation connection mechanism is fixedly connected to the inner side of the transfer seat 4, and pulp is added into the filter cartridge 1 through the feed head 3. At this time, the filter plate 2 filters the pulp entering the filter cartridge 1. At the same time, the transfer seat 4 rotates to scrape and clean the impurities retained after filtering on the top of the filter plate 2. The impurities are affected by the transfer seat 4. The scraping inertia affects the rise, and the centrifugal force drives the impurities to move to the outside of the filter plate 2, and discharges the filter cartridge 1 through the slag outlet 6, thereby ensuring the filtering effect of the filter plate 2 and the convenience of slag cleaning. The installation and connection mechanism includes a mounting ring 9, a connecting groove 10 and a connecting block 11. The mounting ring 9 is fixedly connected to the inner side of the transfer seat 4, and the connecting groove 10 is provided on both sides of the top of the mounting ring 9. The connecting block 11 is movably connected to the inside of the connecting groove 10. When the rotating shaft 13 cooperates with the transfer seat 4 to work, it is convenient for the user to perform a rotational connection operation between the transfer seat 4 and the rotating shaft 13, thereby avoiding the situation where the transfer seat 4 is difficult to install and use when in use, thereby improving the installation and connection convenience of the transfer seat 4.

[0033] Reference Figure 2-Figure 4 In a preferred embodiment, a motor 12 is installed on the top of the filter cartridge 1, and a rotating shaft 13 connected to the output end of the motor 12 is installed inside the filter cartridge 1. The inner side of the connecting block 11 is fixedly connected to the outer side of the rotating shaft 13. When the transfer seat 4 cooperates with the filter plate 2, a rotating force can be applied to the rotating seat through the mounting ring 9 to avoid the situation where the transfer seat 4 is difficult to rotate to transfer and clean the impurities on the top of the filter plate 2 when it is working, thereby improving the rotation and cleaning effect of the transfer seat 4. A screw hole 14 is opened inside the connecting block 11, and the internal thread of the screw hole 14 is connected with a bolt 15. The bottom of the bolt 15 is threadedly connected to the inner wall of the connecting groove 10.

[0034] Reference Figure 3 In a preferred embodiment, a drain port 16 is provided on the surface of the baffle 5, and a plurality of drain ports 16 are provided and are equidistantly distributed. When the baffle 5 cooperates with the transfer seat 4 to work, the impurities blocked by the baffle 5 can be drained, thereby avoiding the situation where the baffle 5 becomes difficult to drain and the impurities move away from the baffle 5, thereby improving the drainage effect of the baffle 5. A filter screen 17 is provided on the top of the transfer seat 4, and a plurality of filter screens 17 are provided and are equidistantly distributed. The outer side of the filter screen 17 is fixedly connected to the inner wall of the drain port 16, so that when the drain port 16 is used in conjunction with the baffle 5, the impurities can be filtered and blocked, thereby avoiding the situation where the impurities pass through the drain port 16 and penetrate the baffle 5 when the drain port 16 is working, thereby improving the drainage and material blocking effect of the drain port 16.

[0035] Reference Figure 2 In a preferred embodiment, a stabilizing seat 18 located at the bottom of the rotating shaft 13 is fixedly connected to the inner wall of the filter cartridge 1, and a stabilizing port 19 is opened on the top of the stabilizing seat 18. The bottom of the rotating shaft 13 is located inside the stabilizing port 19. When the rotating shaft 13 cooperates with the transfer seat 4 to work, the bottom of the rotating shaft 13 can be stabilized to avoid shaking of the bottom of the rotating shaft 13 when working, thereby improving the working stability of the rotating shaft 13. A liquid blocking ring 20 is fixedly connected to the inner wall of the filter cartridge 1. A plurality of liquid blocking rings 20 are provided, and the plurality of liquid blocking rings 20 are equidistantly distributed. The bottom of the liquid blocking ring 20 contacts the top of the baffle 5. When the slag port 6 cooperates with the transfer seat 4 to work, the pulp liquid moving downward from the inside of the filter cartridge 1 can be blocked to avoid the pulp liquid entering the inside of the slag port 6 during the downward movement. Therefore, the liquid blocking effect of the slag port 6 is improved.

[0036] Specifically, the working process or working principle of the closed slurry filtering device is as follows: when in use, when used for the first time, hold the mounting ring 9 to drive the connecting groove 10 to align with the connecting block 11, and make the connecting block 11 enter the inside of the connecting groove 10, then rotate the bolt 15 to cooperate with the screw hole 14, connect and position the connecting block 11 and the connecting groove 10, connect the transfer seat 4 to the rotating shaft 13, and make the transfer seat 4 located on the top of the filter plate 2, and then connect the motor 12 to the external power supply through the wire. When the external pulp to be filtered enters the filter cartridge 1 through the feed head 3, the filter plate 2 filters and removes impurities on the pulp after entering the filter cartridge 1. At this time, the motor 12 drives the transfer seat 4 to rotate through the rotating shaft 13 to cooperate with the mounting ring 9 to scrape and clean the impurities filtered and retained on the top of the filter plate 2. At the same time, since the transfer seat 4 is arranged in a trapezoidal shape, the impurity cleaning process An upward guiding force is applied to the impurities, prompting the impurities to move up and contact the baffle 5. After the baffle 5 contacts the impurities, the residual pulp in the impurities is filtered by the rotation inertia through the drain port 16 and the filter screen 17. The filtered impurities are affected by the centrifugal force of the transfer seat 4 and the baffle 5 and move outward to contact the inner wall of the filter cartridge 1. When the transfer seat 4 cooperates with the baffle 5 to drive the impurities to align with the slag port 6, the impurities enter the transfer shell 7 through the slag port 6 and are discharged from the filter cartridge 1 through the slag port 6. In this process, the liquid blocking ring 20 blocks the pulp liquid flowing downward from the inside of the filter cartridge 1, so that the pulp liquid flowing downward against the inner wall of the filter cartridge 1 is staggered with the slag port 6. At the same time, the stabilizing frame cooperates with the stabilizing port 19 to stabilize the bottom of the rotating shaft 13, to ensure the stability of the rotating shaft 13 driving the transfer seat 4 to clean impurities, and to prompt the filter plate 2 to stably filter the pulp liquid.

[0037] It should be noted that the motor 12 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
