Technical Field
[0001] This utility model relates to the field of paper product manufacturing technology, specifically to a pulp deslagging device for paper product manufacturing. Background Technology
[0002] Paper, also known as felt paper, is made from raw materials containing plant fibers through processes such as pulping, conditioning, papermaking, and processing. It can be used for writing, drawing, printing books and newspapers, packaging, etc. In the manufacturing process of paper products, pulp preparation is a crucial step. Pulp is a fibrous material made from plant fibers through various processing methods. It can be classified according to the processing method into mechanical pulp, chemical pulp, and chemimechanical pulp; it can also be classified according to the fiber raw materials used into wood pulp, straw pulp, hemp pulp, reed pulp, sugarcane pulp, bamboo pulp, rag pulp, etc. During the pulping process, the pulp may contain impurities such as mud and sand. If these impurities are not removed, they will seriously affect the quality of the paper.
[0003] In existing pulp deslagging equipment, the filter screen accumulates sediment on its surface during operation. If not cleaned in time, this sediment can clog some of the filter screen's holes. After deslagging is completed, the residue flows out from the discharge port. Because the residue has a low density, it easily adheres to the discharge pipe wall. Excessive adhesion can lead to blockages in subsequent discharge processes, affecting the smoothness of the discharge. Utility Model Content
[0004] To address the problem that existing pulp deslagging equipment suffers from silt buildup on the filter screen during operation, which can clog some of the screen holes if not cleaned promptly, and the low density of the residue easily adsorbing onto the discharge pipe wall after deslagging, leading to blockages and hindering smooth discharge, this invention aims to provide a pulp deslagging device for paper product manufacturing.
[0005] To solve the above technical problems, the present invention adopts the following technical solution: a pulp deslagging device for paper product manufacturing, including a pulp tank, a pulp conveying pipe connected to the upper part of the pulp tank, a discharge pipe connected to the lower surface of the pulp tank, a filter scraping assembly connected to the upper part of the pulp tank, and a pipe anti-clogging assembly fixedly provided on the lower surface of the pulp tank, the pipe anti-clogging assembly being in movable contact with the discharge pipe;
[0006] The filter scraping assembly includes a filter screen plate, which is fixedly connected to the inside of the pulp tank. A fixing frame is fixedly provided on the inner surface of the pulp tank. A screw is rotatably provided on the inner surface of the fixing frame. A sleeve block is threadedly fitted on the outer surface of the screw. A scraper is fixedly provided on one side of the sleeve block. The scraper slides and fits against the upper surface of the filter screen plate. A first motor is fixedly provided on one side of the pulp tank. A first fixing shell is fixedly provided on one side of the pulp tank. The first motor is fixedly connected to the inside of the first fixing shell. A connecting rod is provided at the output end of the first motor. The connecting rod passes through the pulp tank and the fixing frame. The other end of the connecting rod is fixedly connected to one end of the screw. A hollow block is fixedly provided on the side of the pulp tank. A collecting cylinder is connected to the hollow block. A bolt is threadedly inserted into the side of the collecting cylinder. The end of the bolt is threadedly inserted into the inside of the hollow block.
[0007] Preferably, the pipe anti-clogging component includes a hollow plate, which is fixedly connected to the lower surface of the pulp box. A spring is fixedly provided on the inner surface of the hollow plate, and a slider is fixedly provided on the other end of the spring. A collision block is fixedly provided on one side of the slider, and the collision block is in movable contact with the outer surface of the discharge pipe.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0009] 1. This utility model can filter out impurities in pulp through a filter screen. In order to avoid clogging of the screen holes, the connecting rod can be rotated by starting the first motor. The connecting rod drives the screw to rotate, thereby moving the sleeve block along the fixed frame.

Impurities in the pulp can be filtered out through the filter screen 21. In order to avoid the mesh hole from clogging, the connecting rod 27 can be rotated by starting the first motor 26. The connecting rod 27 drives the screw 23 to rotate, thereby allowing the sleeve block 24 to move along the fixed frame 22. The sleeve block 24 drives the scraper 25 to move, scraping off the impurities on the filter screen 21 and letting them enter the collection cylinder 29. The collection cylinder 29 can be disassembled by rotating the bolt 291 to clean the impurities inside.
