A bottom scraper is fixedly connected to the bottom of the rotating rod.

[0007] Furthermore, T-shaped grooves are evenly distributed on the inner wall of the circular groove, a feeding channel is fixedly connected between the outer wall of the cross and the inner wall of the circular groove, a T-shaped block is engaged in the T-shaped groove, a filter box is fixedly connected to the bottom of the T-shaped block, and filter holes are evenly distributed on the outer wall of the filter box.

[0008] Furthermore, a discharge channel is connected through the bottom of the tank, and a discharge valve is rotatably connected to the discharge channel.

[0009] Furthermore, upright plates are fixedly connected to both sides of the top of the tank. A sliding groove is provided on the inner wall of the upright plate. A horizontal plate is fixedly connected to the top of the upright plate. A cylinder is fixedly connected to the middle of the top surface of the horizontal plate. A push rod is fixedly connected to the output end of the cylinder and passes through the horizontal plate. A connecting plate is fixedly connected to the bottom of the push rod. Slider blocks are fixedly connected to the outer walls on both sides of the connecting plate. Connecting columns are fixedly connected to both ends of the bottom of the connecting plate.

[0010] Furthermore, a controller is fixedly connected to one side of the top of the base plate, and support legs are fixedly connected to the four corners of the bottom of the base plate.

[0012] Furthermore, the maximum extension length of the springs is greater than the radius of the filter box, and the outer wall of the side scraper abuts against the inner wall of the filter box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-consistency deslagging device for pulp purification adopts a novel structural design, the specific details of which are as follows:

[0014] (1) This high-consistency deslagging device for pulp purification is equipped with side scrapers and bottom scrapers. During the operation of the equipment, the side scrapers abut against the inner wall of the filter box. As the telescopic stirring rod rotates, it can effectively scrape off the impurities on the inner wall of the filter box. When the telescopic stirring rod retracts, the removal parts on the telescopic stirring rod remove the impurities on the outer surface of the telescopic stirring rod. The bottom scraper can clean the impurities at the bottom of the filter box, ensuring that the impurities are fully removed, improving the pulp purification effect, and avoiding the impact of impurity residue on paper quality. Utilizing the elastic effect of the spring itself, the spring can keep the side scraper in close contact with the inner wall of the filter box. Since the material of the filter box is carbon fiber composite material, at the beginning of operation, the side scraper will hit the inner wall of the filter box, causing the filter box to vibrate, which makes the impurities fall off the inner wall of the filter box to the bottom, enhancing the cleaning effect.

[0015] (2) The high-consistency slag remover for pulp purification is equipped with a cylinder. The push rod at the output end drives the connecting plate to move. The slider on the connecting plate slides in the groove of the vertical plate to ensure the stability of the movement. The bottom connecting column is connected to the top plate, thereby realizing the lifting of the filter box, which facilitates the maintenance and replacement of the filter box in the later stage, improves work efficiency, and reduces work delays caused by filter box problems.

[0016] Furthermore, the layout of components such as the feed channel, filter box, and discharge channel is reasonable, which facilitates the feeding, filtering, and discharge of pulp and ensures stable operation of the equipment. Attached Figure Description

[0026] 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.

[0027] This utility model provides the following technical solution: a high-consistency slag remover for pulp purification.

[0028] Example 1: A high-consistency desander for pulp purification, which, through the side scraper 142 and bottom scraper 152, can effectively remove impurities from the inner wall of the filter box 17, such as... Figure 1 - Figure 5As shown, the device includes a tank body 1 and a bottom plate 3 fixedly connected to the bottom of the tank body 1. Engaging grooves 11 are evenly distributed on the upper part of the inner wall of the tank body 1. Engaging blocks 111 are movably connected within the engaging grooves 11. A top plate 12 is fixedly connected between the engaging blocks 111. A circular groove 121 is formed on the top plate 12. A cross 123 is fixedly connected to the inner wall of the circular groove 121. A servo motor 13 is fixedly connected to the top of the cross 123. A rotating rod 131 is fixedly connected to the output end of the servo motor 13. A multi-stage telescopic stirring rod 14 is evenly fixedly connected to the outer wall of the rotating rod 131. Removal parts 141 are fixedly connected between each stage of the telescopic stirring rod 14. A side scraper 142 is fixedly connected to the side of the telescopic stirring rod 14 away from the rotating rod 131. Support blocks 15 are fixedly connected to both outer walls of the telescopic stirring rod 14. A spring 151 is fixedly connected to the outer wall of the support block 15. The side of the spring 151 away from the support block 15 is fixedly connected to the side scraper 142. The bottom of the rotating rod 131 is fixedly connected to the bottom scraper 152. T-shaped grooves 122 are evenly opened on the inner wall of the circular groove 121. A feed channel 124 is fixedly connected between the outer wall of the cross 123 and the inner wall of the circular groove 121. A T-shaped block 16 is engaged in the T-shaped groove 122. A filter box 17 is fixedly connected to the bottom of the T-shaped block 16. Filter holes 171 are evenly opened on the outer wall of the filter box 17. A discharge channel 18 is connected through the bottom of the tank 1. A discharge valve 181 is rotatably connected to the discharge channel 18. The maximum extension length of the spring 151 is greater than the radius length of the filter box 17. The outer wall of the side scraper 142 abuts against the inner wall of the filter box 17.

[0029] During the slag removal process, the pulp enters the filter box 17 inside the tank 1 through the feed channel 124. The feed channel 124 is connected between the outer wall of the cross 123 and the inner wall of the circular groove 121, providing a passage for the pulp to enter. Then, the servo motor 13 is started, and the rotating rod 131 at its output end drives the telescopic stirring rod 14 to rotate. The removal element 141 on the telescopic stirring rod 14 stirs the pulp, causing impurities in the pulp to separate from the pulp. The pulp is filtered through the filter holes 171 on the outer wall of the filter box 17, and the impurities are intercepted inside the filter box 17. The purified pulp... The slurry flows out of the filter box 17 through the filter hole 171. At the beginning of operation, the side scraper 142 will hit the inner wall of the filter box 17, causing impurities to fall off the inner wall of the filter box 17. During the rotation of the telescopic stirring rod 14, the side scraper 142 is always in close contact with the inner wall of the filter box 17 under the action of the spring 151. As the telescopic stirring rod 14 rotates, the side scraper 142 scrapes off the impurities attached to the inner wall of the filter box 17. The bottom scraper 152 at the bottom of the rotating rod 131 rotates synchronously to clean the impurities at the bottom of the filter box 17 and prevent the accumulation of impurities from affecting the filtration effect.

[0030] Example 2: Unlike Example 1, the cylinder 23 is used to lift the filter box 17, facilitating its later maintenance and replacement. Figure 6 - Figure 7 As shown, upright plates 2 are fixedly connected to both sides of the top of tank 1. A sliding groove 21 is provided on the inner wall of the upright plate 2. A horizontal plate 22 is fixedly connected to the top of the upright plate 2. A cylinder 23 is fixedly connected to the middle of the top surface of the horizontal plate 22. A push rod 231 is fixedly connected to the output end of the cylinder 23 and passes through the horizontal plate 22. A connecting plate 24 is fixedly connected to the bottom of the push rod 231. A slider 241 is fixedly connected to the outer walls on both sides of the connecting plate 24. A connecting column 242 is fixedly connected to both ends of the bottom of the connecting plate 24. A controller 31 is fixedly connected to one side of the top of the bottom plate 3. Support legs 32 are fixedly connected to the four corners of the bottom of the bottom of the bottom plate 3. An air pump 4 is fixedly connected to both ends of the top of the bottom plate 3. A pipe 41 is fixedly connected to the output end of the air pump 4. The pipe 41 passes through the bottom of the bottom plate 3 and the bottom of the tank 1. A one-way valve 42 is fixedly connected to the pipe 41.

[0031] When the filter box 17 needs maintenance or replacement, start the cylinder 23. The push rod 231 at the output end of the cylinder 23 extends downward, driving the connecting plate 24 to move downward. The sliders 241 on both sides of the connecting plate 24 slide in the grooves 21 of the vertical plate 2 to ensure smooth movement. The connecting column 242 at the bottom of the connecting plate 24 is connected to the filter box 17, lifting the filter box 17 upward for easy operation. The purified pulp is discharged through the discharge channel 18 at the bottom of the tank 1. Rotating the discharge valve 181 can control the discharge speed and flow rate. Start the air pumps 4 at both ends of the top of the bottom plate 3 to inject high-pressure gas into the tank 1 through the pipe 41. Under the action of high-pressure gas, the pulp is always in a tumbling state, which can ensure that the insoluble matter inside is dispersed very evenly, making the pulp discharge smoother.

[0032] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
