[0023] As shown in Figures 1-7 The utility model discloses a centrifugal device, including the warehouse body, be equipped with filter drum 1 and material layer controller 2 in the warehouse body, filter drum 1 is driven by rotating device 3, and the top of warehouse body is equipped with cleaning telescopic link 4, and the movable rod 5 of cleaning telescopic link 4 is placed in the warehouse body, and the bottom of movable rod 5 is fixed with drive warehouse 28, and drive warehouse 28 is fixed with drive motor 6, and the output shaft of drive motor 6 penetrates the bottom end of drive warehouse 28, and the bottom end of output shaft is fixed with brush cylinder 7, and the lateral wall of brush cylinder 7 is fixed with brush tooth, and brush tooth can be with the inside wall of filter drum 1 and resist, and the lateral wall of movable rod 5 is fixed with support disc 8, and the bottom surface of support disc 8 is fixed with a plurality of scraping telescopic link 9, and scraping telescopic link 9 is connected with scraping cylinder 10, and scraping cylinder 10 can accommodate brush cylinder 7 and brush tooth, and the outside wall of scraping cylinder 10 is equipped with scraping knife 11, and scraping knife 11 and the inside wall of filter drum 1 resist, and the lateral wall of movable rod 5 is connected with washing pipe 13 through connecting rod 12. Filter drum 1 and rotating device are all prior art. Filter drum 1, rotating device 3, material layer controller 2 and drive motor 6 are all prior art. Cleaning telescopic link 4 and scraping telescopic link 9 are all 14 prior art hydraulic telescopic link, pneumatic telescopic link or screw jacks and other prior art. Cleaning telescopic link 4 can be fixed on the warehouse body.

[0024] In the process of centrifugal operation, the thickness of the material layer gradually increases to trigger the material layer controller 2, and then the centrifugal device stops feeding, and then the high-speed water flow sprayed through the washing pipe 13 washes the material layer, and after washing, the filter drum 1 is driven by the rotating device 3 to rotate at high speed and dehydrates the material layer. Then start the cleaning telescopic rod 4, the movable rod 5 of the cleaning telescopic rod 4 drives the driving bin 28, the supporting disc 8, the scraping telescopic rod 9 and the scraping drum 10 to move downward, so that the scraping knife 11 on the side wall of the scraping drum 10 cuts into the material layer, and at the same time the rotating device 3 drives the filter drum 1 to rotate at low speed, and the scraping knife 11 can scrape off the material layer on the inner wall of the filter drum 1. When the scraping knife 11 scrapes off most of the material layer on the inner wall of the filter drum 1, the scraping telescopic rod 9 is retracted and the scraping drum 10 is away from the brush cylinder 7, and then the driving motor 6 in the driving bin 28 drives the brush cylinder 7 to rotate. The brush cylinder 7 and the brush teeth thereon can thoroughly clean the tiny pores on the inner wall of the filter drum 1 under the action of centrifugal force, so as to remove the residues that are difficult to scrape off. In the process of cleaning, the high-speed water flow sprayed through the washing pipe 13 can also clean the brush teeth or the filter drum 1.

[0025] As shown in Figures 6-9 The upper end of the filter drum 1 is fixed with an upper fixed ring 14, and the bin body in the filter drum 1 is rotatably connected with a lower rotating ring 15. A cylindrical bag shaking device 16 is fixed between the upper fixed ring 14 and the lower rotating ring 15, and the bag shaking device 16 is arranged between the scraping drum 10 and the filter drum 1. The side wall of the bottom end of the filter drum 1 is provided with a limiting hole 17, and the outer side wall of the lower rotating ring 15 is fixed with a protrusion 18 which penetrates the filter drum 1 along the limiting hole 17. The protrusion 18 arranged on one side of the filter drum 1 is provided with a fixed hole 19, and the axis of the fixed hole 19 is parallel to the axis of the filter drum 1. The outer side wall of the filter drum 1 is fixed with a fixed telescopic rod 20, and the end of the fixed telescopic rod 20 can be arranged in the fixed hole 19. An annular sliding groove is arranged in the bin body, and a sliding block is arranged on the bottom surface of the lower rotating ring 15. The sliding block slides along the annular sliding groove, so that the lower rotating ring 15 rotates with the bin body. The bag shaking device 16 is a filter bag made of polyester fiber or polypropylene fiber.

[0026] In order to prevent too much material from remaining on the scraper 11 after cleaning, causing too much material to adhere to the brush cylinder 7, before the brush cylinder 7 cleans the filter cylinder 1, the fixed telescopic rod 20 is first controlled to retract, so that the fixed telescopic rod 20 is away from the fixed hole 19. At this time, the rotating device drives the filter cylinder 1 to rotate forward and backward at a high speed. The filter cylinder 1 rotates, which drives the upper fixed ring 14 to rotate. The upper fixed ring 14 drives the upper end of the bag shaking device 16 to rotate. The lower rotating ring 15 rotates under the action of centrifugal force and the pulling force of the bag shaking device 16. Therefore, the lower rotating ring 15 rotates with the upper fixed ring 14, and the rotation of the lower rotating ring 15 is limited by the protrusion 18 and the limiting hole 17, which ensures the stability and accuracy of the rotation. When the upper fixed ring 14 and the lower rotating ring 15 rotate, the upper and lower ends of the bag shaking device 16 rotate alternately. This alternating rotation causes the sidewall of the bag shaking device 16 to form a wave shape, which can make the remaining material more quickly and completely separate from the bag shaking device 16, thereby greatly reducing the workload of the brush cylinder 7 and improving the service life of the brush teeth. In comparison, the prior art achieves unloading by straightening the filter bag, which can also remove residual filter cake, but the residual material layer is not easy to completely fall off due to strong adhesion. After unloading is completed, the bag shaking device 16 drives the lower rotating ring 15 to reset under the action of its own restoring force. At this time, the fixed hole 19 corresponds to the fixed telescopic rod 20. The fixed telescopic rod 20 is then made to penetrate into the fixed hole 19, so that the filter cylinder 1 is fixed relative to the lower rotating ring. By increasing the bag shaking device 16, liquid or gas is more easily discharged through the bag shaking device 16, while solid particles are trapped on the surface of the bag shaking device 16, forming a filter cake. The bag shaking device 16 can also serve as a protective layer for the filter cylinder 1 to protect the filter cylinder 1 and reduce the risk of clogging of the filter cylinder 1.

[0027] As shown in Figures 1-5 The driving motor 6 is a double-output shaft motor. One end of the double-output shaft motor away from the brush cylinder 7 is fixed with a half gear 21. The side wall of the driving bin 28 is provided with a driving hole. A rotating gear 22 is rotatably arranged in the driving hole. The rotating gear 22 can engage with the half gear 21. A sleeve 23 is rotatably connected to the side wall of the movable rod 5. A plurality of driven teeth 24 are fixed to the inner side wall of the sleeve 23. The driven teeth 24 engage with the rotating gear 22 and can rotate in the driving hole. The connecting rod 12 is fixed to the outer side wall of the sleeve 23. The sleeve 23 and the side wall of the movable rod 5 are connected by a torsional spring 25. The double-output shaft motor and the torsional spring are both prior art.

[0028] In use, the double-output shaft motor drives the half gear 21 to rotate, the half gear 21 drives the rotating gear 22, the rotating gear 22 drives the sleeve 23 to rotate through the driven gear 24, and the sleeve 23 and the connecting rod 12 can make the washing pipe 13 rotate along the axis of the driving bin 28, when the half gear 21 is disengaged from the rotating gear 22, the sleeve 23 is reset through the torsional spring 25, and the next half gear 21 and the rotating gear 22 are engaged, so that the reciprocating swing of the washing pipe 13 is realized, the swing function of the washing pipe 13 is realized, the cleaning effect of the scraping cylinder 10 and the brush cylinder 7 is improved, and the cleaning degree of the scraping cylinder 10 and the brush cylinder 7 is ensured, and the working efficiency and reliability of the whole centrifugal device are improved.

[0029] As shown in Figure 6 , 7 , the bin body comprises a top cover 26, a through hole 27 is arranged on the top cover 26, a support is fixed on the top cover 26, and the cleaning telescopic rod 4 is fixed on the support.

[0030] The top cover 26 can be conveniently opened to maintain and clean the brush cylinder 7 and the washing pipe 13 in the inside. The cleaning telescopic rod 4 can be fixed at a certain height through the support, so that the brush cylinder 7 and the washing pipe 13 can be placed on the top cover 26 when not in use, the interference and obstruction of the brush cylinder 7 and the washing pipe 13 in the bin body to the centrifugal process are effectively reduced, the space in the bin body is effectively utilized, the structure of the centrifugal device is more compact, and the working efficiency and smoothness of the whole centrifugal device are improved.

[0031] As shown in Figure 2 , 4 , the brush teeth are silica gel strips. The silica gel strips have good flexibility and wear resistance, can effectively remove the material residues attached to the filter cylinder 1, reduce the risk of scratching the filter cylinder 1, improve the cleaning effect and service life, and the softness of the silica gel material can reduce the risk of scratching the inner wall of the filter cylinder 1 compared with the hard brush teeth.
