Description

Technical Field

[0001] This utility model belongs to the field of pulp shredder cleaning technology, specifically a pulp shredder cleaning device. Background Technology

[0002] Pulp shredders use the mechanical force generated by the flying knife rollers and bottom knives to cut, crush, knead, split, swell, and refine various fibrous pulps. At the same time, they cause displacement and deformation of cell walls and rupture of the outer layers of primary and secondary cell walls. After the pulp shredder is used, the pulp adhering to the inner wall of the shredder needs to be cleaned, thus requiring a pulp shredder cleaning device.

[0003] Existing pulp shredders use cleaning devices to clean the wallpaper pulp inside the shredder tank, eliminating the need for workers to use cleaning tools to clean the inner wall of the shredder;

[0004] However, the above solution still has some problems. The height of the cleaning device is fixed, which makes the cleaning effect on the debris at the bottom of the inner wall of the pulp crusher poor, resulting in a decline in cleaning quality. Therefore, a pulp crusher cleaning device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes a cleaning device for a pulp crusher.

[0006] The technical solution adopted by this utility model to solve its technical problem is a pulp shredder cleaning device, including: a shredder body, a cylinder installed on the top of the shredder body, the telescopic end of the cylinder extending into the interior of the shredder body, a hollow frame fixedly connected to the telescopic end of the cylinder, a scraper fixedly connected to the outer surface of the hollow frame, the outer side of the scraper being in contact with the inner wall of the shredder body, bristles fixedly connected to the outer surface of the hollow frame, the bristles being located below the scraper, a water outlet hole opened on the outer surface of the hollow frame, a first filter screen fixedly connected inside the water outlet hole, a feed pipe fixedly connected to the top of the shredder body, a discharge pipe fixedly connected to the bottom of the shredder body, and a drain pipe fixedly connected to the bottom of the shredder body. The first filter screen is located inside the water outlet hole, thereby blocking the pulp and preventing it from entering the interior of the hollow frame.

[0007] Preferably, both the discharge pipe and the drain pipe are equipped with control valves, and a water inlet pipe is installed on the top of the crusher body, with one end of the water inlet pipe located inside the crusher body. The opening and closing of the discharge pipe and the drain pipe can be controlled by the control valves, thereby meeting the needs of crusher operation and cleaning.

[0008] Preferably, one end of the water inlet pipe is fixedly connected to the upper surface of the hollow frame, one end of the drain pipe is equipped with a water tank, the other end of the water inlet pipe is connected to a second filter screen, and the other end of the water inlet pipe extends into the interior of the water tank. The second filter screen can filter out finer slurry in the clean water, preventing slurry from entering the water inlet pipe and causing blockage.

[0009] Preferably, the water tank has a water inlet, a water pump is installed on the upper surface of the water tank, the water pump is connected to the water inlet pipe, and the inner wall of the water tank has symmetrical fixing grooves. By operating the water pump, the clean water in the water tank can be drawn into the water inlet pipe, which facilitates cleaning and use.

[0010] Preferably, the water tank is provided with a receiving plate inside, and the two sets of fixing slots are slidably connected with fixing frames inside. The fixing frames are located in the fixing slots and fix the positions of the third filter screen and the receiving plate to prevent the cleaning water from impacting the third filter screen when it enters the water tank through the drain pipe, thus preventing the third filter screen from moving.

[0011] Preferably, a third filter screen is fixedly connected to one side of each of the two sets of fixing frames. One side of the third filter screen is connected to the upper surface of the receiving plate. The incoming slurry is blocked by the third filter screen and stays above the receiving plate. By lifting the third filter screen upward, the slurry on the receiving plate can be cleaned.

[0012] The advantages of this invention are as follows: Activating the cylinder moves the hollow frame, scraper, and brush along the inner wall of the pulverizer body, scraping off the pulp adhering to the inner wall. Simultaneously, the water pump draws clean water from the tank into the hollow frame, which is then sprayed out through the outlet and the first filter screen. This, in conjunction with the scraper and brush, washes the inner wall of the pulverizer while scraping, preventing drier pulp from floating inside the pulverizer body. The adhering pulp falls directly to the bottom of the pulverizer body, preventing it from re-adhering to the inner wall and thus improving the cleaning quality of the inner wall.

[0013] The cleaned water from this invention enters the water tank through the drain pipe. Simultaneously, the pulp entering is blocked by the third filter and remains above the receiving plate. Thus, the water drawn into the inlet pipe is clean water. Furthermore, the second filter can filter the pulp again, preventing pulp from entering the inlet pipe and causing blockage. This allows the clean water to be reused multiple times, reducing water waste and downtime, enabling the cleaning device to operate continuously and improving the cleaning efficiency of the pulp shredder.

Detailed Implementation

[0021] 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 scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a pulp shredder cleaning device includes: a shredder body 1, a cylinder 2 installed on the top of the shredder body 1, the telescopic end of the cylinder 2 extending into the interior of the shredder body 1, a hollow frame 3 fixedly connected to the telescopic end of the cylinder 2, a scraper 4 fixedly connected to the outer surface of the hollow frame 3, the outer side of the scraper 4 adhering to the inner wall of the shredder body 1, bristles 5 fixedly connected to the outer surface of the hollow frame 3, the bristles 5 being located below the scraper 4, a water outlet 6 opened on the outer surface of the hollow frame 3, a first filter screen 7 fixedly connected inside the water outlet 6, a feed pipe 8 fixedly connected to the top of the shredder body 1, a discharge pipe 9 fixedly connected to the bottom of the shredder body 1, a drain pipe 10 fixedly connected to the bottom of the shredder body 1, control valves 11 being installed inside both the discharge pipe 9 and the drain pipe 10, and a water inlet pipe 12 installed on the top of the shredder body 1, with one end of the water inlet pipe 12 located inside the shredder body 1.

[0023] When processing various fiber pulps, the pulp adheres to the inner wall of the pulp shredder. After use, the pulp adhering to the inner wall needs to be cleaned, thus requiring a pulp shredder cleaning device. In actual use, when processing office paper pulp, various fiber pulps are added to the inside of the shredder body 1 through the feed pipe 8. Before this, it is necessary to ensure that the discharge pipe 9 and drain pipe 10 are in a closed state. Then, the fiber pulp is processed through the shredder body 1. After processing, the discharge pipe 9 is opened through the control valve 11 on the discharge pipe 9, allowing the processed fiber pulp to be discharged and collected from the shredder body 1. Then, the control valve 11 on the discharge pipe 9 is closed, and the control valve on the drain pipe 10 is opened simultaneously. Valve 11 activates cylinder 2, moving the hollow frame 3 up and down along the inner wall of the crusher body 1. This causes the scraper 4 and brush 5 to move synchronously, scraping off the slurry adhering to the inner wall of the crusher body 1. Simultaneously, water pump 16 draws clean water from water tank 14 into inlet pipe 12, allowing the clean water to enter the hollow frame 3 and be discharged outward through outlet hole 6 and first filter screen 7. This, in conjunction with scraper 4 and brush 5, washes the inner wall of the crusher while scraping the material, preventing the drier slurry from floating inside the crusher body 1 due to the wind generated by the movement of the hollow frame 3. This allows the adhering slurry to fall directly to the bottom of the crusher body 1 and then enter the water tank 14 through drain pipe 10, thereby improving the cleaning quality of the inner wall of the crusher body 1.

[0024] Please see Figure 1-5As shown, one end of the water inlet pipe 12 is fixedly connected to the upper surface of the hollow frame 3, one end of the drain pipe 10 is equipped with a water tank 14, the other end of the water inlet pipe 12 is connected to a second filter screen 13, and the other end of the water inlet pipe 12 extends into the interior of the water tank 14. A water inlet 15 is provided on the water tank 14, a water pump 16 is installed on the upper surface of the water tank 14, the water pump 16 is connected to the water inlet pipe 12, the inner wall of the water tank 14 is symmetrically provided with fixing grooves 17, a receiving plate 18 is provided inside the water tank 14, a fixing frame 19 is slidably connected inside the two sets of fixing grooves 17, a third filter screen 20 is fixedly connected to one side of the two sets of fixing frames 19, and one side of the third filter screen 20 is connected to the upper surface of the receiving plate 18.

[0025] Sufficient cleaning water is added to the water tank 14 through the water inlet 15, and the length of the water inlet pipe 12 must meet the length required for the hollow frame 3 to move. Then, the cylinder 2 is activated to move the hollow frame 3, scraper 4, brush bristles 5, and one end of the water inlet pipe 12 synchronously. Simultaneously, the water pump 16 is activated to draw water into the hollow frame 3 through the water inlet pipe 12 for cleaning. The cleaned water enters the water tank 14 through the drain pipe 10. The slurry entering simultaneously is blocked by the third filter screen 20 and remains above the receiving plate 18. Therefore, the water drawn into the water inlet pipe 12 is clean cleaning water. At the same time, the second filter screen 13 can filter the slurry again, preventing slurry from entering the water inlet pipe 12 and causing blockage. This allows the cleaning water to be reused multiple times. This reduces water waste and downtime, allowing the cleaning device to operate continuously and improving the cleaning efficiency of the pulp shredder. Pulling the third filter 20 and the fixing frame 19 upwards will move the receiving plate 18 synchronously, allowing the receiving plate 18 to be removed from the water tank 14 for cleaning of the pulp on the receiving plate 18. Placing the receiving plate 18, the fixing frame 19, and the third filter 20 into the water tank 14, while pushing the fixing frame 19 downwards along the fixing groove 17, will fix the positions of the third filter 20 and the receiving plate 18, preventing the cleaning water from impacting the third filter 20 when it enters the water tank 14 through the drain pipe 10, thus improving the filtration intensity of the pulp.

[0026] Working principle: After the slurry inside the crusher body 1 is discharged, the control valve 11 on the drain pipe 10 is opened, and sufficient cleaning water is added to the water tank 14 through the water inlet 15. The water pump 16 is started to draw water into the hollow frame 3 through the water inlet pipe 12. The cylinder 2 is started to move the hollow frame 3 up and down along the inner wall of the crusher body 1, driving the scraper 4 and brush 5 to move synchronously, thus scraping off the slurry adhering to the inner wall of the crusher body 1. At the same time, the cleaning water is discharged outward through the water outlet 6 and the first filter screen 7. In conjunction with the scraper 4 and brush 5, the inner wall of the crusher is washed while scraping the material, preventing the drier slurry from floating inside the crusher body 1 due to the wind generated when the hollow frame 3 moves. This allows the adhering slurry to fall directly to the bottom of the crusher body 1 and then enter the water tank 14 through the drain pipe 10. The slurry entering is blocked by the third filter screen 20 and stays on the receiving plate 18. The cleaning water can be reused through the inlet pipe 12, and the second filter screen 13 can filter the pulp again, preventing pulp from entering the inlet pipe 12 and causing blockage. This allows the cleaning water to be reused multiple times, reducing water waste and downtime, and enabling the cleaning device to operate continuously, thus improving the cleaning efficiency of the pulp crusher. Pulling the third filter screen 20 and the fixing frame 19 upwards will move the receiving plate 18 synchronously, allowing the receiving plate 18 to be removed from the water tank 14, and the pulp on the receiving plate 18 can be cleaned. Placing the receiving plate 18, the fixing frame 19 and the third filter screen 20 into the water tank 14, while pushing the fixing frame 19 downwards along the fixing groove 17, will fix the position of the third filter screen 20 and the receiving plate 18, thus preventing excessive pulp from clogging the third filter screen 20 and reducing downtime.
