In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a paper pulp adhesive removal device, including a housing 1. The housing 1 is made of high-strength stainless steel, which has good corrosion resistance and structural strength, ensuring that it will not deform or be damaged due to chemical erosion of the pulp or stress generated by equipment operation during long-term operation. Its inner wall is specially polished, and the surface roughness reaches Ra0.8μm or less, which reduces the resistance when the pulp flows in the housing 1, reducing the possibility of material residue and blockage. A round rod 2 is rotatably connected to the housing 1. The round rod 2 is made of high-quality alloy steel and is heat-treated to improve its hardness and toughness, ensuring that it will not bend or break under large torque. The surface of the round rod 2 is chrome-plated with a thickness of 0.05-0.1mm to enhance its wear resistance and corrosion resistance, while reducing the coefficient of friction with the sleeve 7, making the sleeve 7 slide more smoothly on the round rod 2. A screw conveyor 3 is installed in a portion of the round rod 2. Support rods 4 are connected to one end and the other end of the housing 1. Multiple sets of support rods 4 are slidably connected at one end and the other end to corresponding arc-shaped mesh plates 5. The support rods 4 are made of aluminum alloy, which is lightweight and high-strength, facilitating the installation and removal of the arc-shaped mesh plates 5. The connection between the end of the support rod 4 and the arc-shaped mesh plate 5 uses a sliding groove slider structure. The sleeve 7 is slidably connected to the round rod 2, and multiple sets of scrapers 9 are connected to the sleeve 7. The scrapers 9 are made of polyurethane rubber, which has high elasticity, high wear resistance, and good corrosion resistance. The joint between the scraper 9 and the arc-shaped screen 5 is designed to be arc-shaped, matching the curvature of the arc-shaped screen 5. Multiple sets of scrapers 9 contact the corresponding arc-shaped screen 5. One end of the sleeve 7 is attached to a ring 8, which is connected to the round rod 2. The other end of the sleeve 7 is attached to a threaded sleeve 10, which is threadedly connected to the threaded area of ​​the round rod 2. The round rod 2 drives the rotation of the sleeve 7 and the scraper 9. The scraper 9 can centrifuge and screen the pulp that falls into the internal space formed by multiple sets of support rods 4 and the arc-shaped screen 5. At the same time, the scraper 9 can also continuously clean the material that is attached to and clogging the arc-shaped screen 5.

[0022] One end of the housing 1 is connected to a motor 6. The model of the motor 6 is selected according to the actual working requirements. The motor 6 is connected to the round rod 2.

[0023] One end of the housing 1 is connected to a feed inlet 13, and the other end of the housing 1 is connected to multiple sets of discharge outlets 12. Both the feed inlet 13 and the multiple sets of discharge outlets 12 are funnel-shaped designs, which facilitates the injection or discharge of materials.

[0024] The housing 1 is connected to a partition 11, which is used to prevent pulp and adhesives falling into the housing 1 from being discharged at the same outlet 12.

[0025] Among them, the multiple sets of scrapers 9 are staggered at one end and the other end. When the scrapers 9 rotate with the sleeve 7, they can discharge the adhesive that cannot pass through the arc-shaped mesh plate 5 through the opening at one end of the internal space formed by the multiple sets of support rods 4 and the arc-shaped mesh plate 5.

[0026] The shell 1 has an opening at one end, which allows the arc-shaped mesh plate 5, sleeve 7 and scraper 9 to be easily installed and removed.

[0027] The specific usage and function of this embodiment are as follows:

[0028] In use, the motor 6 can be connected to an external power supply and drive device to rotate the round rod 2. This round rod 2 then drives the auger 3 and sleeve 7 to rotate. When the auger 3 and sleeve 7 drive the scraper 9 to rotate, pulp is injected at the feed inlet 13. The pulp falls into the housing 1 and is conveyed by the auger 3, moving into the internal space formed by multiple sets of support rods 4 and the arc-shaped screen 5. At this time, the sleeve 7 drives the scraper 9 to rotate, and the multiple sets of scrapers 9 can then centrifugally screen the pulp, leaving large particles of adhesive material in the internal space, while the fluid other than the adhesive material passes through the arc-shaped screen. Plate 5 is discharged from a set of discharge ports 12 near the motor 6. Due to the tilted placement of scraper 9, the adhesive will be discharged through the opening at one end of the internal space formed by multiple sets of support rods 4 and arc-shaped screen plate 5 as scraper 9 rotates, and discharged from a set of discharge ports 12 away from the motor 6. This completes the removal of adhesive from the pulp. Subsequently, the arc-shaped screen plate 5 can be directly separated from the support rod 4, and arc-shaped screen plates 5 with different apertures can be replaced to adapt to the work. Alternatively, the threaded sleeve 10 can be separated from the round rod 2, so that the sleeve 7 can drive the scraper 9 to separate from the round rod 2 for disassembly and maintenance.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
