Description

Technical Field

[0001] This utility model relates to the field of paper tube base paper technology, and more specifically, it relates to a pulp and impurity separation device for paper tube base paper production. Background Technology

[0002] Paper tube base paper is an industrial paper specifically designed for processing paper tubes. It is made from recycled waste paper or wood pulp, and is produced through high-viscosity pulping and long-wire papermaking to create a high-strength, high-toughness thick paper with a basis weight typically between 200 and 500 g / m². It is pressure-resistant, bend-resistant, and has low water absorption. The surface is treated with sizing or coating, and it can be directly used for subsequent processes such as winding, slitting, and edge grinding. It is a basic material for the production of paper cores and paper tubes in industries such as textiles, film, papermaking, and logistics.

[0003] Pulp processed from waste paper often contains impurities, which can affect the quality of the base paper. Therefore, it is necessary to filter these impurities. However, most existing filters rely on gravity to allow the pulp to pass through the filter screen, resulting in low filtration efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pulp and impurity separation device for paper tube base paper production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pulp and impurity separation device for paper tube base paper production, comprising a shell, an inlet on one side of the shell, a slag discharge outlet on the other side of the shell, an outlet at the lower end of the shell, an inlet inclined plate and a slag discharge inclined plate fixedly connected to the shell, the inlet inclined plate passing through the inlet, the slag discharge inclined plate passing through the slag discharge outlet, and an arc-shaped filter screen fixedly connected between the inlet inclined plate and the slag discharge inclined plate; A horizontal shaft is rotatably connected to the housing. One end of the horizontal shaft is connected to the output shaft of a motor via a coupling. The motor is mounted on the housing. Multiple filter components are arranged on the horizontal shaft. Each filter component includes an arc plate, a lifting arm, and a pressure roller. The arc plate is located on one side of the horizontal shaft. Multiple lifting arms are fixedly connected to the arc plate. The ends of the multiple lifting arms away from the arc plate are fixedly connected to the horizontal shaft. A pressure roller is rotatably connected to the arc plate, and the pressure roller abuts against the arc-shaped filter screen.

[0006] Preferably, each of the filter components further includes a main scraper, which is fixedly connected to the arc plate and rubs against the arc-shaped filter screen.

[0007] Preferably, each of the filter components further includes a comb plate, which is fixedly connected to the arc plate, and the comb plate and the main scraper are located on both sides of the pressure roller.

[0008] Preferably, each of the filter components further includes a secondary scraper, which is fixedly connected to the arc plate and rubs against the pressure roller.

[0009] Preferably, one side of each of the feed inclined plate, slag discharge inclined plate, and arc-shaped filter screen is fixedly connected to a side rail, and the other side of each of the feed inclined plate, slag discharge inclined plate, and arc-shaped filter screen is fixedly connected to another side rail.

[0010] Preferably, a support arc is fixedly connected between the feed inclined plate and the slag discharge inclined plate, and the support arc abuts against the lower end face of the arc-shaped filter screen.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The horizontal shaft supports the arc plate through multiple booms. The horizontal shaft drives the arc plate to rotate through the booms. The arc plate drives the pressure roller on it to rotate around the axis of the horizontal shaft. During the rotation, the pressure roller will come into contact with the arc-shaped filter screen and squeeze the pulp on the arc-shaped filter screen, thereby accelerating the filtration of the pulp and improving the filtration efficiency. 2. Before the pressure roller squeezes the pulp on the arc-shaped filter screen, the comb plate will first come into contact with the pulp on the arc-shaped filter screen, thereby spreading the piled pulp evenly, which makes it easier for the pressure roller to squeeze.

[0018] Reference Figures 1 to 4This utility model provides a technical solution: a pulp and impurity separation device for paper tube base paper production, including a shell 1. A feed inlet 2 is opened on one side of the shell 1, through which pulp enters the shell 1. A slag discharge outlet 3 is opened on the other side of the shell 1, through which impurities are discharged from the shell 1. A discharge outlet 4 is opened at the lower end of the shell 1, through which filtered pulp is discharged. A feed inclined plate 5 and a slag discharge inclined plate 6 are fixedly connected to the shell 1. The feed inclined plate 5 penetrates the feed inlet 2, and the slag discharge inclined plate 6 penetrates the slag discharge outlet 3. An arc-shaped filter screen 7 is fixedly connected between the feed inclined plate 5 and the slag discharge inclined plate 6. Figure 1 and Figure 2 The pulp is fed onto the feed ramp 5, and the pulp flows down along the feed ramp 5 onto the arc-shaped filter screen 7. The pulp is filtered through the arc-shaped filter screen 7, thereby intercepting impurities in the pulp. A horizontal shaft 8 is rotatably connected to the housing 1. One end of the horizontal shaft 8 is connected to the output shaft of a motor 9 via a coupling. The motor 9 is mounted on the housing 1 and can drive the horizontal shaft 8 to rotate. Multiple filter components are provided on the horizontal shaft 8, and the horizontal shaft 8 drives the multiple filter components on it to rotate. Each filter component includes an arc plate 10, a hanging arm 11, and a pressure roller 12. The arc plate 10 is located on one side of the horizontal shaft 8. Multiple hanging arms 11 are fixedly connected to the arc plate 10. The ends of the multiple hanging arms 11 away from the arc plate 10 are all fixedly connected to the horizontal shaft 8. A pressure roller 12 is rotatably connected to the arc plate 10, and the pressure roller 12 abuts against the arc-shaped filter screen 7. like Figure 3 and Figure 4 The horizontal axis 8 supports the arc plate 10 through multiple hanging arms 11. The horizontal axis 8 drives the arc plate 10 to rotate (the horizontal axis 8 rotates counterclockwise in the figure). The arc plate 10 drives the pressure roller 12 on it to rotate around the axis of the horizontal axis 8. During the rotation, the pressure roller 12 will come into contact with the arc-shaped filter screen 7 and squeeze the pulp on the arc-shaped filter screen 7, thereby accelerating the filtration of the pulp and improving the filtration efficiency. Impurities intercepted by the arc-shaped filter screen 7 will accumulate on it, and the rotating pressure roller 12 can push these impurities onto the slag discharge inclined plate 6, and the impurities will be discharged from the housing 1 along the slag discharge inclined plate 6.

[0019] Specifically, each of the filter components further includes a main scraper 13, which is fixedly connected to the arc plate 10 and rubs against the arc-shaped filter screen 7. like Figure 2 and Figure 3 When the pressure roller 12 squeezes the pulp on the arc-shaped filter screen 7, the main scraper 13 can scrape off and push the impurities on the arc-shaped filter screen 7, thereby pushing these impurities onto the slag discharge inclined plate 6, making the scraping and pushing of impurities more thorough.

[0020] Specifically, each of the filter components further includes a comb plate 14, which is fixedly connected to the arc plate 10, and the comb plate 14 and the main scraper 13 are located on both sides of the pressure roller 12, respectively. like Figure 3 and Figure 4 Before the pressure roller 12 squeezes the pulp on the arc-shaped filter screen 7, the comb plate 14 will first come into contact with the pulp on the arc-shaped filter screen 7, thereby spreading the piled-up pulp evenly, which is convenient for the pressure roller 12 to squeeze.

[0021] Specifically, each of the filter components further includes a secondary scraper 15, which is fixedly connected to the arc plate 10 and rubs against the pressure roller 12. like Figure 4 The secondary scraper 15 can scrape off the pulp on the pressure roller 12, preventing the pulp from sticking to the pressure roller 12.

[0022] Specifically, one side of each of the feed inclined plate 5, the slag discharge inclined plate 6, and the arc-shaped filter screen 7 is fixedly connected to a side rail 16, and the other side of each of the feed inclined plate 5, the slag discharge inclined plate 6, and the arc-shaped filter screen 7 is fixedly connected to another side rail 16. Figure 2 The pulp is blocked by two side rails 16 to prevent it from falling through the sides of the feed inclined plate 5, the slag discharge inclined plate 6 and the arc-shaped filter screen 7.

[0023] Specifically, a support arc 17 is fixedly connected between the feed inclined plate 5 and the slag discharge inclined plate 6. The support arc 17 abuts against the lower end face of the arc-shaped filter screen 7, such as... Figure 3 and Figure 4 The arc-shaped filter screen 7 is further supported by the arc support 17.

[0024] Working principle: The pulp is fed into the feed inclined plate 5, and the pulp flows down along the feed inclined plate 5 to the arc-shaped filter screen 7, where it is filtered. The horizontal shaft 8 supports the arc plate 10 through multiple hanging arms 11. The horizontal shaft 8 drives the arc plate 10 to rotate through the multiple hanging arms 11. The arc plate 10 drives the pressure roller 12 on it to rotate around the axis of the horizontal shaft 8. During the rotation, the pressure roller 12 will come into contact with the arc-shaped filter screen 7 and squeeze the pulp on the arc-shaped filter screen 7, thereby accelerating the filtration of the pulp and improving the filtration efficiency.
