[0024] Please refer to Figures 1-4 , the present invention provides a technical solution for a filter residue removal structure on the inner wall of a centrifuge:

[0025] Embodiment 1:

[0026] According to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a filter residue removal structure on the inner wall of a centrifuge includes a centrifuge body 1. A motor 304 is arranged at the bottom of the centrifuge body 1. The output end of the motor 304 is in transmission connection with a centrifugal cylinder 5, and the centrifugal cylinder 5 adopts a hole mesh structure. An annular support plate 2 is sleeved outside the upper end of the centrifuge body 1, and the annular support plate 2 is fixedly connected to the centrifuge body 1. Rotating sliders 306 are slidably connected to the front and rear sides of the upper surface of the annular support plate 2. An inner wall distance adjustment mechanism 3 is arranged between the two rotating sliders 306. The inner wall distance adjustment mechanism 3 includes L-shaped arms 301, a bidirectional threaded rod 302, driving sliders 303, a motor 304, connecting arms 305 and rotating sliders 306. The number of L-shaped arms 301 is set to two, and the lower ends of the two L-shaped arms 301 are respectively fixedly connected to the upper surface of the rotating slider 306. A bidirectional threaded rod 302 is rotatably connected between the two L-shaped arms 301. Driving sliders 303 are threadedly connected to both sides of the bidirectional threaded rod 302. Filter residue removal mechanisms 4 are arranged on the lower surfaces of the two driving sliders 303. A motor 304 is arranged outside the L-shaped arms 301. The output end of the motor 304 is in transmission connection with the bidirectional threaded rod 302. Connecting arms 305 are fixedly connected to the left and right ends of the inner sides of the two L-shaped arms 301. The lower ends of the left and right connecting arms 305 are fixedly connected to the outside of the centrifugal cylinder 5. The lower end of the centrifugal cylinder 5 is rotatably connected to the inner bottom end of the centrifuge body 1. Opposite-thread structures are arranged on both sides of the bidirectional threaded rod 302. When the bidirectional threaded rod 302 rotates, the driving sliders 303 on both sides thereof move in opposite directions. A limiting slide rail 307 is fixedly connected to the lower surface of the L-shaped arm 301. The driving slider 303 is slidably connected to the lower surface of the limiting slide rail 307.

[0027] During specific use, for the filter residue removal structure on the inner wall of a centrifuge of the present utility model, before cleaning the filter residue on the inner wall of the centrifuge body 1, start the motor 304. The output end of the motor 304 is in transmission connection with the bidirectional threaded rod 302 to drive the bidirectional threaded rod 302 to rotate. Opposite-thread structures are provided on both sides of the bidirectional threaded rod 302. When the bidirectional threaded rod 302 rotates, the two driving sliders 303 move in opposite directions along the threads of the bidirectional threaded rod 302, thereby adjusting the distance between the filter residue removal mechanism 4 below the driving slider 303 and the inner wall of the centrifuge body 1. In this way, through the cooperation of the bidirectional threaded rod 302 and the driving slider 303, the adjustment of the inner wall distance can be achieved to meet the filter residue removal requirements of different thicknesses.

[0028] Embodiment 2:

[0029] Based on Embodiment 1, as Figure 1 and Figure 2 shown, the filter residue removal mechanism 4 includes an inner wall fitting plate 401 and an inclined scraper 402. The upper end of the inner wall fitting plate 401 is fixedly connected to the lower surface of the driving slider 303, and the lower end of the inner wall fitting plate 401 is arranged at the bottom end inside the centrifuge body 1. An inclined scraper 402 is fixedly connected to the outside of the inner wall fitting plate 401. The upper end and the lower end of the inclined scraper 402 are inclined. The inclination angle of the inclined scraper 402 helps to generate a cutting force when scraping the filter residue, making the filter residue easier to be removed.

[0030] During specific use, for the filter residue removal structure on the inner wall of a centrifuge of the present utility model, when cleaning the filter residue on the inner wall of the centrifuge body 1, through the inner wall distance adjustment mechanism 3, the inclined scraper 402 outside the inner wall fitting plate 401 is made to fit the inner wall of the centrifuge body 1. Then, an appropriate amount of cleaning agent and water are added into the centrifuge body 1. The motor 304 structure configured in the centrifuge body 1 drives the centrifugal cylinder 5 to rotate. After the centrifugal cylinder 5 rotates, the L-shaped support arm 301 connected to it through the connecting arm 305 rotates accordingly. At this time, the entire inner wall cleaning mechanism and the filter residue removal mechanism 4 rotate with the centrifugal cylinder 5. During this process, the inclined scraper 402 can scrape the filter residue on the inner wall of the centrifuge body 1, achieving the cleaning effect of the filter residue on the inner wall surface of the centrifuge body 1.
