For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] See also Figures 1 to 4The present invention provides a technical solution: a paper pulp adhesive removal system, including a shell 1, which is made of high-strength stainless steel and has good corrosion resistance and structural strength, ensuring that it will not be deformed or damaged due to chemical erosion of 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, so that the resistance of pulp flowing in the shell 1 is smaller, and the possibility of material residue and blockage is reduced. The shell 1 is rotatably connected with a round rod 2, which is made of high-quality alloy steel and is tempered to improve its hardness and toughness, ensuring that it will not bend or break when subjected to a large torque. The surface of the round rod 2 is chrome-plated with a coating thickness of 0.05-0.1mm to enhance its wear resistance and corrosion resistance, while reducing the friction coefficient with the sleeve 7, so that the sleeve 7 can slide more smoothly on the round rod 2. A auger 3 is installed in part of the round rod 2. One end and the other end of the housing 1 are connected to the support rod 4. One end and the other end of multiple groups of support rods 4 are respectively connected to the corresponding arc-shaped mesh plates 5 for sliding. The support rod 4 is made of aluminum alloy, which has the characteristics of light weight and high strength, and is convenient for installing and removing the arc-shaped mesh plates 5. The connection between the end of the support rod 4 and the arc-shaped mesh plate 5 adopts a slide block structure. The round rod 2 is slidably connected to the sleeve 7, and the sleeve 7 is connected to multiple groups of scrapers 9. The scrapers 9 are made of polyurethane rubber material, which has high elasticity, high wear resistance and good corrosion resistance. The scraper 9 is designed to be arc-shaped at the joint between it and the curved mesh plate 5, matching the curvature of the curved mesh plate 5. Multiple groups of scrapers 9 are respectively in contact with the corresponding curved mesh plates 5. A ring body 8 is fitted on one end of the sleeve 7, and the ring body 8 is connected to the round rod 2. A threaded sleeve 10 is fitted on the other end of the sleeve 7, and the threaded sleeve 10 is threadedly connected to the threaded area of ​​the round rod 2. The round rod 2 is used to drive the sleeve 7 and the scraper 9 to rotate. The scraper 9 can centrifugally screen the pulp that falls into the internal space formed by the multiple groups of support rods 4 and the curved mesh plate 5, and the scraper 9 can also continuously clean the materials that are attached to and block the curved mesh plate 5.

[0022] Among them, a motor 6 is connected to one end of the shell 1 , and the model of the motor 6 is selected according to actual working requirements. The motor 6 is connected to the round rod 2 .

[0023] Among them, one end of the shell 1 is connected to a feed port 13, and the other end of the shell 1 is connected to multiple groups of discharge ports 12. The feed port 13 and the multiple groups of discharge ports 12 are both funnel-shaped in design, which can facilitate the injection or discharge of materials.

[0024] The shell 1 is connected with a partition 11 , and the partition 11 is used to prevent the pulp and adhesives that fall into the shell 1 from being discharged at the same discharge port 12 .

[0025] Among them, one end and the other end of the multiple groups of scrapers 9 are staggered. When such scrapers 9 rotate with the sleeve 7, they can discharge the adhesives that cannot pass through the curved mesh plate 5 from one end of the opening of the internal space formed by the multiple groups of support rods 4 and the curved mesh plate 5.

[0026] Among them, an opening is processed at one end of the shell 1, so that the arc-shaped mesh plate 5, the sleeve 7 and the scraper 9 can be easily installed and removed.

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

[0028] When the present invention is in use, the motor 6 can be connected to an external power source and a driving device to drive the round rod 2 to rotate, so that the round rod 2 can drive the auger 3 and the sleeve 7 to rotate. When the auger 3 and the sleeve 7 drive the scraper 9 to rotate, the pulp is injected at the feed port 13, and the pulp will fall into the shell 1 and be transported by the auger 3, and move to the internal space formed by the multiple groups of support rods 4 and the arc-shaped mesh plate 5. At this time, the sleeve 7 drives the rotation of the scraper 9, and the multiple groups of scrapers 9 can drive the pulp to perform centrifugal screening to leave large particles of adhesives in the internal space, while the fluid other than the adhesives passes through the arc-shaped mesh plate. 5, discharged at a group of discharge ports 12 near the motor 6, and the adhesives will be discharged from the opening at one end of the internal space formed by the multiple groups of support rods 4 and the arc-shaped mesh plates 5 due to the inclined placement of the scraper 9. When the scraper 9 rotates, it will be discharged through the guide of the scraper 9 and discharged at a group of discharge ports 12 away from the motor 6, thus completing the adhesive removal work in the pulp. Subsequently, the arc-shaped mesh plates 5 can be directly separated from the support rods 4, and arc-shaped mesh plates 5 with different apertures can be replaced to adapt to the work. The threaded sleeve 10 can also be separated from the round rod 2 to drive the sleeve 7 to separate the scraper 9 from the round rod 2 for disassembly and maintenance.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
