Abstract
Description
Technical Field
[0001] This utility model relates to the field of yarn tube pulp technology, specifically a filter device for yarn tube pulp with anti-clogging function. Background Technology
[0002] Yarn tube base pulp is a specialized pulp used to produce yarn tube base paper. Its process and performance characteristics involve fiber treatment, impurity filtration, and formulation optimization. It mainly uses recycled resources such as waste corrugated cardboard and old yarn tubes as raw materials to reduce production costs and improve resource utilization. The raw materials are initially decomposed by a hydraulic pulper, and wood impurities (such as sawdust and sand) are removed by a filter layer. Secondary refining: The fiber pulp is refined using a secondary refining device to ensure uniform cellulose dispersion. A high-speed mixer is used to fully mix the fibers and additives, and multi-stage stirring rods and crushing blades are used to improve pulp uniformity and crushing efficiency. The paper is then formed on a wire or cylinder paper machine, with fiber distribution optimized by a wet pressing device, and paper thickness controlled by a hydraulic system.
[0003] In the prior art, CN218666902U discloses a waste paper recycling and filtration device for yarn tube base paper production, which belongs to the field of waste paper recycling technology. It includes a filter box, with support columns fixedly installed at the four corners of the top of the filter box. A dissolving tank is fixedly connected between the tops of the four support columns. A return water tank is connected to one end of the filter box. Connecting pipes are symmetrically connected between the top of the inner wall of the filter box and the bottom of the inner wall of the dissolving tank. A valve is fixedly connected to the outer surface of the connecting pipe. While the above-mentioned solution has many advantages, it also has the following disadvantages: The device uses a screen to filter pulp, but because the paper scraps remaining in the pulp are of varying sizes, prolonged use will cause the paper scraps to clog the filter holes, thus reducing the filtration efficiency of the screen. In addition, the liquid is stirred by a stirring rod, but the stirring rod cannot contact the upper part of the screen, which will cause a large amount of paper scraps to accumulate or clog the surface of the screen, thus further reducing the filtration efficiency of the screen and causing clogging problems. Utility Model Content
[0004] The purpose of this invention is to provide a filtration device for yarn tube raw pulp with anti-clogging function, so as to solve the problem that the filtration efficiency of the screens used in the current yarn tube raw pulp is reduced due to clogging.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for raw pulp in yarn tubes with anti-clogging function, comprising a housing, a cleaning rod and a filter cylinder rotatably mounted on the inner wall of the housing, and inner grooves formed on both sides of the inner wall of the housing located on the filter cylinder, and filter holes arranged in a circumferential array on the outer side of the filter cylinder, and needle rods arranged in a circumferential array fixedly mounted on the outer side of the cleaning rod, the needle rods cooperating with the filter holes, and a rotating assembly for driving the filter cylinder and cleaning rod to rotate on the housing, the filter cylinder and cleaning rod being arranged parallel to each other, with the filter cylinder located below the cleaning rod.

[0007] Preferably, the rotating assembly includes a small toothed ring and a large toothed ring that mesh with each other. The small toothed ring is fixedly sleeved on the outside of the cleaning rod, and the large toothed ring is fixedly sleeved on the outside of the filter cartridge. Two partitions are rotatably sleeved on the outside of the filter cartridge through a sealed bearing. The partitions have through holes at corresponding positions relative to the cleaning rod, and the partitions are rotatably sleeved on the outside of the cleaning rod through the sealed bearing. The partitions are fixed to the inner wall of the box.
[0008] Preferably, a turntable and a rotating ring are rotatably arranged on the inner walls of the two inner tanks, and a spiral auger rod is arranged between the turntable and the rotating ring. The outer side of the spiral auger rod is in contact with the inner wall of the filter cylinder, and a stirring rod distributed in a circular array is fixedly arranged on the inner wall of the spiral auger rod.
[0009] Preferably, two scraper rods are fixedly installed on the inner wall of the chamber, and the two scraper rods respectively contact the two sides of the filter cartridge.

Detailed Implementation
[0016] 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.
[0017] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a filter device for raw paper pulp with anti-clogging function, including a box body 1. A cleaning rod 4 and a filter cylinder 3 are rotatably arranged on the inner wall of the box body 1. Inner grooves 2 are formed on both sides of the inner wall of the box body 1 located on the filter cylinder 3. Filter holes 5 are formed on the outer side of the filter cylinder 3 in a circumferential array. Needle rods 16 are fixedly arranged in a circumferential array on the outer side of the cleaning rod 4. The needle rods 16 cooperate with the filter holes 5. A rotating assembly 6 is provided on the box body 1 to drive the filter cylinder 3 and the cleaning rod 4 to rotate. The filter cylinder 3 and the cleaning rod 4 are arranged parallel to each other, and the filter cylinder 3 is located below the cleaning rod 4. Specifically, the outer diameter of the needle rod 16 is smaller than the diameter of the filter hole 5, and when the needle rod 16 is inserted into the corresponding filter hole 5 cavity, the needle rod 16 does not contact the inner wall of the filter hole 5.
[0018] like Figure 1 and Figure 2 As shown, feed pipe 7 and drain pipe 8 are fixedly connected to both sides of the box 1, and discharge pipe 14 is fixedly connected to the bottom of the box 1. Feed pipe 7 and drain pipe 8 are respectively connected to two inner tanks 2. Solenoid valves are installed on feed pipe 7, drain pipe 8 and discharge pipe 14. Specifically, the feed pipe 7, drain pipe 8 and discharge pipe 14 are opened or closed using solenoid valves. Solenoid valves are existing technology equipment, and their specific usage and installation are not described in detail in this application.
[0019] like Figure 1 and Figure 3 As shown, the rotating assembly 6 includes a small toothed ring 601 and a large toothed ring 602 that mesh with each other. The small toothed ring 601 is fixedly sleeved on the outside of the cleaning rod 4, and the large toothed ring 602 is fixedly sleeved on the outside of the filter cartridge 3. Two partitions are rotatably sleeved on the outside of the filter cartridge 3 through a sealed bearing. The partitions have through holes at corresponding positions relative to the cleaning rod 4, and the partitions are rotatably sleeved on the outside of the cleaning rod 4 through the sealed bearing. The partitions are fixed to the inner wall of the housing 1.
[0020] like Figure 1 and Figure 4 As shown, a turntable 9 and a rotating ring 10 are respectively rotatably arranged on the inner walls of the two inner tanks 2. A spiral auger rod 11 is arranged between the turntable 9 and the rotating ring 10. The outer side of the spiral auger rod 11 is in contact with the inner wall of the filter cylinder 3. A stirring rod 13 arranged in a circular array is fixedly arranged on the inner wall of the spiral auger rod 11.
[0021] like Figure 1 and Figure 2 As shown, two scraper rods 12 are fixedly installed on the inner wall of the housing 1, and the two scraper rods 12 are in contact with the two sides of the filter cartridge 3 respectively.
[0022] like Figure 1 - Figure 4 As shown, two servo motors 15 are installed inside the housing 1. The output ends of the two servo motors 15 are fixedly connected to the axis of the turntable 9 and the end of the cleaning rod 4, respectively. The servo motors 15 are electrically connected to the power supply.
[0023] like Figure 1 and Figure 2 As shown, the bottom wall of the box 1 is inclined towards the central area, and the discharge pipe 14 is located in the central area of the bottom of the box 1. Working principle: Pulp is fed into the housing 1 through the feed pipe 7, and the pulp is located inside the filter cylinder 3. The water level of the conveyed pulp is lower than the height of the top of the filter cylinder 3. The servo motor 15 drives the turntable 9 to rotate. The turntable 9 uses the auger rod 11 and the stirring rod 13 to stir the pulp. After stirring for a certain period of time, the discharge pipe 14 is opened to discharge the pulp filtered from the filter cylinder 3. After filtration, larger paper scraps remain in the filter cylinder 3. The auger rod 11 continues to rotate, scraping away and pushing the remaining paper scraps to the drain pipe 8 for discharge. Cleaning liquid can be conveyed into the housing 1. At the same time, the drain pipe 8 is opened and the discharge pipe 14 is closed. The cleaning liquid and the auger rod 11 work together to carry the larger paper scraps into the drain pipe 8 for discharge. During the filtration of pulp, the servo motor 15 drives the cleaning rod 4 and the small toothed ring 601 to rotate simultaneously. The small toothed ring 601, in turn, drives the filter cartridge 3 to rotate in the opposite direction via the large toothed ring 602. This causes the filter cartridge 3 to rotate slowly, allowing the needles 16 on the cleaning rod 4 to be inserted into the corresponding filter holes 5 to clear the blockages in the filter holes 5. As the filter cartridge 3 rotates slowly, the scraper 12 also scrapes off the paper scraps attached to the outer wall of the filter cartridge 3.
[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
