[0002] Wood pulp is paper pulp made from wood. It is classified according to pulping materials, pulping methods and uses, such as sulfate softwood pulp, mechanical wood pulp, and refined wood pulp. Wood pulp is the main material used, accounting for more than 90% of the total pulp volume. Wood pulp is not only used in papermaking, but also widely used in other industrial sectors. During the production of wood pulp, a large amount of waste liquid is generated. The waste liquid contains a lot of residue, which not only pollutes the environment, but also makes the subsequent treatment of the waste liquid troublesome. Therefore, it is necessary to separate the waste liquid and residue of wood pulp.

[0003] The workshop is dusty and humid, which can easily cause the equipment parts to rust and become clogged, affecting the smooth operation. Some small particles of residue are still mixed in the waste liquid. Moreover, long-term continuous operation can cause the equipment to wear out and age, reducing the separation accuracy. As a result, the final separated residue has a high liquid content, and the waste liquid still contains a lot of impurities. Therefore, this utility model proposes a waste liquid residue separation device for wood pulp production to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a waste liquid residue separation device for wood pulp production, which solves the problems in the prior art where long-term continuous operation leads to easy wear and aging of the device, reduced separation accuracy, resulting in high liquid content in the final separated residue and a large amount of impurities remaining in the waste liquid.

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a waste liquid and residue separation device for wood pulp production, including a conveying pipe 1, a separation chamber 2, a discharge pipe 3, a nozzle 4, and a slag discharge pipe 5. The front end of the conveying pipe 1 is connected to the separation chamber 2, and a separation mechanism is provided inside the separation chamber 2. The front end of the bottom of the separation chamber 2 is connected to the discharge pipe 3, and the bottom end of the discharge pipe 3 is connected to the nozzle 4. A slag discharge pipe 5 is provided on one side of the separation chamber 2. A conveying mechanism is provided on the conveying pipe 1. The device is placed on a support, and a hose for discharging wood pulp waste liquid is inserted into the interior of the conveying pipe 1. The wood pulp waste liquid is directly conveyed to the interior of the separation chamber 2 through the conveying mechanism. The residue and liquid in the wood pulp waste liquid are separated by the separation mechanism. Then, the liquid flows through the discharge pipe 3 to the interior of the nozzle 4, and the liquid is sprayed out through the nozzle 4. The residue is discharged to the outside of the separation chamber 2 through the slag discharge pipe 5 by the separation mechanism.

[0019] The separation mechanism includes a filter disc 6, a rotating shaft 7, and a cleaning brush 8. The filter disc 6 is fixedly installed inside the separation chamber 2. The rotating shaft 7 is rotatably connected to the center of the filter disc 6. The cleaning brush 8 is fixedly connected to one end of the rotating shaft 7. One side of the cleaning brush 8 is in contact with the side of the filter disc 6 facing the conveying pipe 1. The rotating shaft 7 is connected to the auger 10 through a coupling. The auger 10 drives the cleaning brush 8 to rotate on one side of the filter disc 6 through the rotating shaft 7. The cleaning brush 8 scrapes the residue on one side of the filter disc 6 to the bottom of the separation chamber 2. When a large amount accumulates, the injection of wood pulp waste liquid into the conveying pipe 1 is stopped. The device is manually turned so that the bottom end of the slag discharge pipe 5 faces downward. A clean water pipe is inserted into the feed pipe 11 to transport clean water from the conveying pipe 1 to the inside of the separation chamber 2. Together with the rotating cleaning brush 8, the residue is swept into the slag discharge pipe 5 and cleaned out of the inside of the separation chamber 2.

[0020] The filter disc 6 includes a shell and a filter cloth. The filter cloth is fixed inside the shell and is made of synthetic fiber. It is formed by interlacing warp and weft yarns. After the wood pulp waste liquid enters the interior of the separation chamber 2, it comes into contact with the filter cloth in the filter disc 6. The fiber woven or non-woven structure of the filter cloth forms porous channels. Residue particles larger than the pore size are directly blocked on the surface of the filter cloth, which plays a filtering role on the residue. The liquid flows through the filter cloth to the discharge pipe 3.

[0021] The conveying mechanism includes a rotary motor 9 and an auger 10. The auger 10 is rotatably connected inside the conveying pipe 1. The rotary motor 9 is installed on one side of the conveying pipe 1. The output end of the rotary motor 9 is fixedly connected to one end of the auger 10. The output end of the rotary motor 9 can drive the auger 10 to rotate inside the conveying pipe 1. The spiral blades on the outside of the auger 10 drive the wood pulp waste liquid and residue to flow automatically towards the separation chamber 2.

[0022] One end of the rotating shaft 7 is fixedly connected to the end of the auger 10 away from the rotating motor 9 via a coupling. The rotating motor 9 is provided with an anti-collision shell on its outer side, which encloses the rotating motor 9 to prevent external objects from directly contacting the rotating motor 9 and to protect the rotating motor 9.

[0023] The top of the conveying pipe 1 is connected to a hopper 12. The hopper 12 and the end adjacent to the feed pipe 11 are both fixedly connected to a connecting plate. A connecting mechanism is provided between the two connecting plates. A flow control valve is provided on the feed pipe 11.

[0024] The connecting mechanism includes clamps 13, threaded rods 14, fixing sleeves 15, and grooves 16. Clamps 13 are symmetrically hinged on both sides of the connecting disc at the top of the feed pipe 11. One end of one clamp 13 is hinged to a threaded rod 14, and one end of the other clamp 13 has a groove 16. One end of the threaded rod 14 passes through the interior of the groove 16 and is threadedly connected to the fixing sleeve 15. Pulling the clamps 13 on both sides of the connecting disc at the top of the feed pipe 11 outwards rotates the connecting disc at the bottom of the collecting hopper 12 to align with the top of this connecting disc. Rotating the two clamps 13 closer together, and then rotating one end of the threaded rod 14 to insert it into the interior of the groove 16, and thus... The groove 16 extends through the fixed sleeve 15 at one end of the groove 16 and is tightened. The fixed sleeve 15 drives the two clamps 13 to retract inward, using the two clamps 13 to clamp the connecting plate and fix the collection hopper 12 to the top of the feed pipe 11. The collection hopper 12 can guide the wood pulp waste liquid into the interior of the feed pipe 11, making the wood pulp waste liquid enter the conveying pipe 1 more smoothly. When disassembling, loosen the fixed sleeve 15, pull the clamps 13 to rotate outward, and take out the collection hopper 12. The flow control valve can control the flow rate of wood pulp waste liquid into the conveying pipe 1, preventing the liquid level of wood pulp waste liquid in the separation chamber 2 from being too high and overflowing outward through the slag discharge pipe 5.

[0025] In this waste liquid and residue separation device for wood pulp production, the rotating shaft 7 is connected to the auger 10 via a coupling. The auger 10 drives the cleaning brush 8 to rotate on one side of the filter disc 6 via the rotating shaft 7. The cleaning brush 8 scrapes the residue on one side of the filter disc 6 to the bottom of the separation chamber 2. When a large amount accumulates, the injection of wood pulp waste liquid into the conveying pipe 1 is stopped, and the device is manually turned so that the bottom end of the slag discharge pipe 5 faces downward. A clean water pipe is inserted into the feed pipe 11, and clean water is transported from the conveying pipe 1 to the inside of the separation chamber 2. Together with the rotating cleaning brush 8, the residue is swept into the slag discharge pipe 5 and cleaned out of the inside of the separation chamber 2.
