[0002] With the improvement of environmental awareness and the emphasis on resource recycling, waste paper recycling and reuse has become an important development direction of the papermaking industry. After the waste paper is recycled, it can be made into pulp for papermaking after a series of processing steps. Among them, pulp filtration is a key step to ensure the quality of pulp. It can remove impurities in the pulp, such as moisture, dust and fine fibers. This step is usually achieved through a pulp filtration device to improve the purity and utilization rate of the pulp. However, the filtration device in the prior art still has certain defects when used and needs to be improved;

[0003] In the pulp filtering device of the prior art, pulp is easily blocked due to fiber entanglement or agglomeration when flowing in the feed pipe. Once blockage occurs, it will not only reduce production efficiency, but also may damage equipment and increase maintenance costs. In addition, due to the lack of an effective auxiliary conveying mechanism, the fluidity of the pulp in the feed pipe is poor, resulting in limited feeding speed of the filtering device, thereby affecting the operating efficiency of the entire production line. Therefore, a pulp filtering device for waste paper recycling is proposed to overcome the above-mentioned defects. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A pulp filtering device for waste paper recycling comprises a filtering part, a support frame is installed on one side of the filtering part, a main feed pipe runs through the filtering part and the support frame, and a motor is installed on one side of the support frame.

[0007] A worm is passed through the main feed pipe, the output end of the motor is connected to the worm, a spiral rod rotates in the main feed pipe, one end of the spiral rod is sleeved with a worm wheel meshing with the worm, an auxiliary feed pipe is passed through the main feed pipe, and a ball valve is arranged on the auxiliary feed pipe.

[0008] Preferably, the filter unit comprises a filter tank and a filter net, a rectangular frame is installed inside the filter tank, and the filter net is placed on the rectangular frame.

[0009] Preferably, a wedge-shaped plate is installed at the bottom of the filter portion, and a support frame is installed at the bottom of the wedge-shaped plate.

[0010] Preferably, a discharge port and two discharge pipes are passed through one side of the filter tank, and the discharge port and the discharge pipes are respectively located on both sides of the filter screen.

[0011] Preferably, a valve is provided on the main feed pipe, and a sealing ring is provided at the connection between the main feed pipe and the worm.

[0012] Preferably, two mounting frames are installed in the main feed pipe, a rotating ring is installed in the middle of the two mounting frames, and the spiral rod rotates between the two rotating rings.

[0013] The utility model has the following beneficial effects:

[0014] 1. Under the cooperation of the screw and the worm gear, when filtering the pulp, the worm gear of the meshing worm is driven to rotate by starting the motor, so that the screw rotates between the two rotating rings, and the screw provides continuous driving force for the transportation of pulp in the main feed pipe, effectively avoiding the blockage problem caused by fiber entanglement or agglomeration of pulp, ensuring the continuity and uniformity of pulp flow, and accelerating the flow speed of pulp in the feed pipe, thereby improving the feeding speed and overall processing capacity of the filtering device, and significantly improving production efficiency;

[0015] 2. With the cooperation of the auxiliary feed pipe and the ball valve, during the pulp transportation process, when blockage occurs in the main feed pipe, the ball valve can be opened to allow the pulp to be transported to the filter section through the auxiliary feed pipe for filtration, thereby ensuring the continuous operation of the production line and reducing production interruptions caused by blockage. This provides double protection for the feed system of the filter section. Even if there is a problem with the main feed pipe, the auxiliary feed pipe can ensure that the pulp supply will not be completely interrupted, thereby improving the reliability of the entire filtration system.
