[0019] 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.

[0020] Reference Figures 1-4 A pulp circulation device includes a tank body 1, an inlet pipe 101 fixedly connected to the top of the tank body 1, an outlet pipe 102 fixedly connected to the side wall of the tank body 1, a filter assembly 2 installed on the inner wall of the tank body 1 for filtering the circulating pulp, an outlet assembly 3 installed on the inner wall of the tank body 1 for filtering the pulp from the outlet pipe 102, and a circulation assembly 4 fixedly connected to the side wall of the tank body 1 for circulating the pulp. The device also includes:

[0021] The filter assembly 2 includes a first filter plate 201, which is fixedly installed on the inner wall of the barrel 1. A servo motor 202 is fixedly connected to the bottom of the barrel 1. A rotating shaft 203 is fixedly connected to the output end of the servo motor 202, and the rotating shaft 203 extends to the top of the barrel 1. A stirring plate 204 is fixedly connected to the side wall of the rotating shaft 203 above the first filter plate 201, and multiple sets of stirring plates 204 are provided.

[0022] A rotating plate 205 is fixedly connected to the side wall of the rotating shaft 203 located below the first filter plate 201. The rotating plate 205 is provided with multiple sets, and multiple sets of holes 206 are opened on the side wall of the rotating plate 205.

[0023] It should be noted that: when pulp is added to the inner cavity of the barrel 1 through the feed pipe 101, the residual impurities and coarse fibers in the pulp will remain on the top of the first filter plate 201, driving the servo motor 202. The servo motor 202 drives the rotating shaft 203 to rotate. During the rotation of the rotating shaft 203, the stirring plate 204 is also rotated, thereby dispersing the impurities and coarse fibers on the top of the first filter plate 201 into the inner cavity of the pulp, preventing impurities from directly entering the circulation component 4 and causing blockage. In addition, the rotating shaft 203 will also drive the rotating plate 205 to rotate. Combined with the holes 206 on the side wall of the rotating plate 205, the residual air bubbles in the pulp can be eliminated.

[0024] Reference Figures 1-4 The discharge assembly 3 includes a second filter plate 301, which is fixedly installed on the inner wall of the barrel 1, and a bottom plate 302 is fixedly connected to the bottom of the second filter plate 301.

[0025] The ramp 302 is inclined toward the discharge pipe 102, and a partition 303 is fixedly connected between the ramp 302 and the second filter plate 301.

[0026] A push plate 304 is fixedly connected to the side wall of the rotating shaft 203 located above the second filter plate 301, and the push plate 304 is in contact with the surface of the second filter plate 301.

[0027] It should be noted that: the pulp liquid falls above the second filter plate 301 after passing through the circulation component 4, and the pulp liquid will directly enter the ramp plate 302. The ramp plate 302 is set to be inclined towards the discharge pipe 102, so that the pulp flows directly out of the discharge pipe 102. When the rotating shaft 203 rotates, it will drive the push plate 304 to rotate. The push plate 304 can not only remove the impurities filtered on the top of the second filter plate 301, but also remove the pulp liquid remaining on the top of the second filter plate 301, so as to avoid long-term accumulation and fiber coagulation that would cause blockage of the second filter plate 301.

[0028] Reference Figures 1-4 The circulation component 4 includes a pump body 401, which is fixedly installed at the bottom of the barrel 1. A connecting pipe 402 is fixedly connected between the pump body 401 and the top of the barrel 1, and the connecting pipe 402 is located above the second filter plate 301.

[0029] A connecting frame 403 is fixedly connected to the side wall of the barrel 1. A sliding column 404 is slidably connected to the side wall of the connecting frame 403. A baffle 405 is fixedly connected to the end of the sliding column 404 located in the inner cavity of the connecting frame 403, and the baffle 405 can close the feed pipe 101.

[0030] A spring 406 is fixedly connected between the end of the sliding column 404 and the connecting frame 403, and a pressing column 407 is fixedly connected to the side wall of the rotating shaft 203, and the pressing column 407 can fit against the baffle 405.

[0031] It should be noted that: the pump body 401 can draw the pulp liquid filtered by the filter assembly 2 below the barrel 1 to the top of the barrel 1 through the connecting pipe 402, and then continue to enter the filter assembly 2 through the discharge assembly 3, thereby starting the circulation and preventing the pulp liquid from stagnating and forming fiber sedimentation. The rotating shaft 203 will drive the extrusion column 407 to rotate and collide with the baffle 405, thereby moving the baffle 405 away from the outlet of the feed pipe 101. At this time, the spring 406 is compressed and generates a rebound force, and the feed pipe 101 can replenish the pulp liquid into the inner cavity of the barrel 1. After the extrusion column 407 moves away from the baffle 405, the baffle 405 returns to its original position under the rebound force of the spring 406 and continues to block the feed pipe 101, thereby realizing the intermittent addition of pulp liquid.

[0032] Operation method: Pulp liquid is added into the inner cavity of the barrel 1 through the feed pipe 101. The residual impurities and coarse fibers in the pulp liquid will stay on the top of the first filter plate 201. The servo motor 202 is driven, and the servo motor 202 drives the rotating shaft 203 to rotate. During the rotation of the rotating shaft 203, the stirring plate 204 is rotated, thereby dispersing the impurities and coarse fibers on the top of the first filter plate 201 into the inner cavity of the pulp liquid, preventing impurities from directly entering the circulation component 4 and causing blockage. Moreover, the rotating shaft 203 will also drive the rotating plate 205 to rotate. Combined with the holes 206 on the side wall of the rotating plate 205, the residual air bubbles in the pulp liquid can be eliminated. The pump body 401 can be used to draw the pulp liquid below the barrel 1 to the top of the barrel 1 through the connecting pipe 402.

[0033] The pulp falls above the second filter plate 301, and the pulp directly enters the ramp plate 302. The ramp plate 302 is set to tilt towards the discharge pipe 102, so that the pulp flows directly out of the discharge pipe 102. When the rotating shaft 203 rotates, it drives the push plate 304 to rotate. The push plate 304 can not only remove the impurities filtered on the top of the second filter plate 301, but also remove the pulp that stays on the top of the second filter plate 301, so as to avoid long-term accumulation and fiber coagulation that would block the second filter plate 301. The rotating shaft 203 drives the extrusion column 407 to rotate and collide with the baffle 405, so that the baffle 405 moves away from the outlet of the feed pipe 101. At this time, the spring 406 is compressed and generates a rebound force, and the feed pipe 101 can replenish the pulp into the inner cavity of the barrel 1. After the extrusion column 407 moves away from the baffle 405, the baffle 405 returns to its original position under the rebound force of the spring 406 and continues to block the feed pipe 101, thereby realizing the intermittent replenishment of pulp.
