[0022] The specific implementation of the present invention is described in detail below with reference to specific embodiments.
[0023] See also Figures 1 to 4The embodiment of the present invention provides a multi-disc concentrator for a bobbin paper production department, which includes: a device body 1, a protective box 2 fixedly connected to the middle of the top of the device body 1, a motor 8 fixedly connected to the middle of the protective box 2, a first rotating shaft 9 fixedly connected to the driving part of the motor 8, a fixed plate 16 fixedly connected to the upper and lower sides of the first rotating shaft 9, a scraper 17 fixedly connected to the other end of the fixed plate 16, a limit plate 21 fixedly connected to the lower side of the protective box 2, and the limit plate 21 is rotated by the rotation of the inner part. The column 23 is rotatably connected to the rocking arm 22, and the bottom end of the rocking arm 22 is fixedly connected to the hammer 14. The main pulley 10 is fixedly connected to the top of the first rotating shaft 9. The main pulley 10 is connected to the secondary pulley 12 through the transmission belt 11. The middle of the secondary pulley 12 is fixedly connected to the second rotating shaft 13. The bottom end of the second rotating shaft 13 is fixedly connected to the disc 18. The bottom end of the disc 18 is fixedly connected to the side away from the center of the circle with a fixed column 19. The top of the rocking arm 22 is matched with the mobile plate 20. When the mobile plate 20 moves, it drives the rocking arm 22 to swing. , the movable plate 20 is connected with a fixed column 19, the movable plate 20 is slidably connected to the inside of the protective box 2, and the fixed column 19 drives the movable plate 20 when it rotates. The bottom of the device body 1 is fixedly connected with a discharge pipe 24, and a spiral disk 15 is installed on the first rotating shaft 9. The discharge port of the spiral disk 15 is provided with a discharge pipe 24. The inner layer of the device body 1 is fixedly connected with a filter screen 7, and the lower right side of the device body 1 is fixedly connected with a liquid outlet 6. First, the bobbin paper production raw material enters the inside of the filter screen 7, and the motor 8 is started at this time to drive the fixed connection with it. The first rotating shaft 9 rotates, driving the spiral disk 15 to rotate inside the filter 7, so that the pulp is squeezed by the spiral disk 15, and the sewage in the pulp flows into the liquid outlet 6 through the filter 7, and the upper and lower fixed plates 16 on the side of the first rotating shaft 9 drive the scraper 17 to move. The scraper 17 scrapes and stirs the material inside the concentrator to prevent the material from accumulating or adhering to the inner wall of the filter 7. At the same time, the main pulley 10 above the first rotating shaft 9 drives the secondary pulley 12 to rotate through the transmission belt 11, thereby rotating the second rotating shaft 13. The disc 18 at the bottom end of the second rotating shaft 13 rotates with it, and the fixed column 19 on the side of the bottom end of the disc 18 away from the center of the circle performs a circular motion accordingly. The fixed column 19 cooperates with the movable plate 20 that is slidably connected inside the protective box 2, and when the fixed column 19 rotates, it drives the movable plate 20 to move. The movement of the movable plate 20 will drive the rocking arm 22 connected thereto to swing.

[0026] The multi-disc concentrator for bobbin paper production, provided by the present invention, operates as follows: First, bobbin paper raw materials enter filter screen 7. At this point, motor 8 is activated, driving first shaft 9, which is fixedly connected to it, to rotate. This drives spiral disc 15 inside filter screen 7, squeezing the pulp against spiral disc 15 and allowing wastewater in the pulp to flow through filter screen 7 and into liquid outlet 6. Furthermore, fixed plates 16 on the upper and lower sides of first shaft 9 drive scrapers 17 to move, scraping and stirring the material inside the concentrator to prevent it from accumulating or adhering to the inner wall of filter screen 7. Simultaneously, primary pulley 10 above first shaft 9 drives secondary pulley 12 via conveyor belt 11, which in turn rotates second shaft 13. Disc 18 at the bottom end of second shaft 13 rotates with it, causing fixed post 19, located on the side of the disc 18 away from the center of the circle, to follow its circular motion. Fixed post 19 cooperates with movable plate 20, which is slidably connected to the inside of protective box 2. Rotation of fixed post 19 drives movable plate 20 to move. The movement of the movable plate 20 will drive the rocking arm 22 connected thereto to swing. The rocking arm 22 rotates in the limit plate 21 through the rotating column 23, so that the hammer 14 at the bottom end of the rocking arm 22 produces a periodic knocking action. This knocking action helps to further disperse the material in the device, prevents the material from accumulating in certain areas, and ensures the smooth progress of the concentration process.
