The water is then sprayed onto the surface of the filter plate through the through-holes in the cleaning pipe, facilitating the cleaning of the filter plate surface. When water flows from the installation cylinder into the docking cylinder, it works with the fan blades to drive the inner liner cylinder to rotate, which in turn drives the cleaning pipe to rotate. The rotation of the cleaning pipe makes the cleaning of the filter plate more comprehensive and deepens the cleaning effect.

[0064] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of this utility model are now described with reference to the accompanying drawings. However, the scope of protection of this utility model is not limited to the following description.

[0065] Reference Figure 1-7 As shown, a sand removal device for kraft paper production using water slurry includes: a base 1; a sand removal unit 2, which is arranged at one end of the top of the base 1; a water inlet unit 4, which is arranged at one end of the sand removal unit 2; and a drainage unit 6, which is arranged at the other end of the top of the base 1. The sand removal unit 2 includes a sand removal cylinder 201, a connecting cylinder 203 fixedly arranged at the top of the sand removal cylinder 201, and a water spray cylinder 204 rotatably arranged at the bottom of the connecting cylinder 203. A water inlet pipe 202 is connected to the top of the connecting cylinder 203. Multiple water spray holes 205 are opened on the outer wall of the water spray cylinder 204. The water inlet unit 4 is arranged at the top of the sand removal cylinder 201, and the drainage unit 6 is connected to the sand removal cylinder 201. The water inlet pipe 202 is connected to a first water supply pipe 3. The first water supply pipe 3 is connected to the water inlet unit 4.

[0066] The present invention provides a technical solution in which, during use, water slurry is introduced into the sand removal cylinder 201 through the water inlet unit 4, and then sediment settles inside the sand removal cylinder 201. The upper water slurry is discharged through the drainage unit 6, and the lower mud and sand are cleaned outward by opening the cylinder door at the bottom of the sand removal cylinder 201. When it is necessary to clean the inside of the sand removal cylinder 201, the water inlet pipe 202 is connected to an external pipe, and then water is introduced into the spray cylinder 204 through the water inlet pipe 22 and sprayed outward through the spray holes 205 to clean the inner wall of the sand removal cylinder 201, washing away the mud and sand adsorbed on the inner wall of the sand removal cylinder 201, achieving an automatic cleaning effect. The spray holes 205 are inclined, and their water outlets are tangent to the inner wall of the sand removal cylinder 201. When spraying water, the recoil force causes the spray cylinder 204 to rotate, which makes the sprayed water more even and enhances the cleaning effect on the inner wall of the sand removal cylinder 201.

[0067] Preferably, the water inlet unit 4 includes: a water inlet tank 401, which is arranged on top of and connected to the sand removal cylinder 201; a filter plate 4015, which is arranged inside the water inlet tank 401; a first water distribution tank 402, which is arranged at one end of the water inlet tank 401; a second water distribution tank 403, which is arranged at the other end of the water inlet tank 401; a first water supply pipe 3, which is connected to the first water distribution tank 402 and the second water distribution tank 403; and a door 405 is hinged to the bottom of the water inlet tank 401.

[0068] The first water tank 402 and the second water tank 403 are each equipped with multiple water spray pipes 406, which extend into the water inlet tank 401; one end of the water spray pipe 406 is provided with a water outlet groove 407.

[0069] Specifically, water slurry is introduced into the sand removal cylinder 201 through the inlet tank 401. The slurry is filtered by the filter plate 4015 to remove sediment. Water from the inlet pipe 202 is introduced into the first distribution tank 402 and the second distribution tank 403 via the first water supply pipe 3, and then into the spray pipe 406. The water is then sprayed onto the inner wall of the inlet tank 401 through the outlet trough 407 to clean the inner wall of the inlet tank 401. The door 405 is opened for easy cleaning and replacement of the filter plate 4015.

[0070] Preferably: a connecting cylinder 4011 is provided on the outer wall of the water inlet tank 401; an installation cylinder 404 is connected to one end of the connecting cylinder 4011; a cleaning pipe 408 is provided inside the water inlet tank 401, and the cleaning pipe 408 is connected to the connecting cylinder 4011; a branch pipe 4016 is arranged on the top of the installation cylinder 404, and the branch pipe 4016 is connected to the first water supply pipe 3; the installation cylinder 404 is connected to the connecting cylinder 4011; multiple through holes are opened on one side of the cleaning pipe 408;

[0071] An inner liner 409 is rotatably mounted inside the mounting cylinder 404; multiple fan blades 4010 are mounted on the outside of the inner liner 409; one end of the inner liner 409 extends into the interior of the docking cylinder 4011; two connecting rods 4014 are mounted on one end of the inner liner 409; a connecting plate 4013 is mounted on one end of the cleaning pipe 408; the connecting rods 4014 are connected to the connecting plate 4013; and a water inlet 4012 is opened at the bottom of one end of the docking cylinder 4011.

[0072] Specifically, water from the first water supply pipe 3 is introduced into the mounting cylinder 404 via the branch pipe 4016, then enters the docking cylinder 4011 through the inlet 4012, and finally enters the cleaning pipe 408. Water is then sprayed onto the surface of the filter plate 4015 through the through-holes in the cleaning pipe 408, facilitating cleaning of the filter plate 4015. When water flows from the mounting cylinder 404 into the docking cylinder 4011, it works with the fan blades 4010 to rotate the inner liner cylinder 409. The connecting rod 4014 causes the inner liner cylinder 409 to rotate the connecting plate 4013, which in turn rotates the cleaning pipe 408. The rotation of the cleaning pipe 408 ensures a more thorough cleaning of the filter plate 4015, enhancing the cleaning effect.

[0073] Preferably, the interior of the sand removal cylinder 201 is connected to a second water supply pipe 5 via a water pump; one end of the second water supply pipe 5 is connected to the drainage unit 6.

Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
