Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal filters, in particular to an isolation type centrifugal filter. Background Art

[0002] An isolating centrifugal filter is a device used to separate solid and liquid mixtures and is widely used across various industrial sectors. It utilizes centrifugal force to separate solid particles from liquid in a mixture, offering high efficiency, rapid speed, and continuous processing. Currently, there are many types of centrifugal filters, but common centrifugal filters are relatively simple in structure and typically feature an open design, which can lead to a high risk of cross-contamination.

[0003] Traditional centrifugal filters generally rely on filter elements, filter papers, etc. for filtration during use. These filter materials consume a large amount of material and are likely to increase filtration costs. Some existing filters only rely on the centrifugal method of the filter cartridge for centrifugal filtration and separation. However, during the separation process, some impurities will still leak out through the centrifugal cartridge holes and flow out with the separated liquid, thus affecting the separation and purification effect.

A drain pipe 8 is connected to one side of the filter barrel 1. A filter shell 9 is provided on one side of the drain pipe 8. The drain pipe 8 is combined with the filter shell 9 to facilitate secondary purification of the separated liquid. A slag discharge pipe 10 is provided at the bottom of the filter barrel 1, and a feed shell 11 is provided on one side of the top of the cover plate 4.

[0025] An annular slide rail 12 is provided inside the filter barrel 1. The annular slide rail 12 cooperates with the slide plate 13 to improve the stability of the centrifugal barrel 6 during rotation. The surface of the centrifugal barrel 6 is fixedly connected to the slide plate 13 used in conjunction with the annular slide rail 12. The top of the cover plate 4 is fixedly connected to a cylinder 14. The output end of the cylinder 14 passes through the interior of the filter barrel 1 and is fixedly connected to an extension rod 15. When separating the material, the cylinder 14 can be driven to drive the extension rod 15 to descend and drive the sealing plug 16 to seal the position of the slag discharge pipe 10 to prevent the medium that has not been separated from flowing out. The bottom of the extension rod 15 is fixedly connected to the sealing plug 16.

[0026] A filter plate 17 is installed inside the filter shell 9. Since the filter plate 17 is L-shaped, it is convenient for the filtered items to stay inside the filter plate 17 for subsequent cleaning work. A plurality of filter holes 18 are provided in a ring shape on the surface of the centrifugal cylinder 6. The filter holes 18 are used to facilitate the diversion of the medium. A cylindrical filter shell 19 is fixedly connected to the surface of the centrifugal cylinder 6. A precision filter screen 20 is inserted into the interior of the cylindrical filter shell 19. The cylindrical filter shell 19 is combined with the precision filter screen 20 to improve the separation effect of the medium.

The fixed connection between the support frame 21 and the filter barrel 1 can improve the stability of the filter shell 9.

[0027] The DC motor 701 is fixed to the top of the connecting frame 3, and the annular teeth 702 are fixed to the bottom of the surface of the centrifugal cylinder 6. The output of the DC motor 701 passes through the bottom of the connecting frame 3 and has a first transmission wheel 703. The surface of the first transmission wheel 703 is provided with a transmission belt 704. One side of the inner part of the transmission belt 704 is connected to the second transmission wheel 705 for transmission. The inner part of the second transmission wheel 705 is fixedly connected to a transmission rod 706. By turning on the DC motor 701 and cooperating with the first transmission wheel 703 to drive the transmission belt 704, the second transmission wheel 705 will drive the transmission rod 706 to make the gear 707 engage the annular teeth 702 to rotate, so that the centrifugal cylinder 6 rotates and separates. The top of the transmission rod 706 passes through the interior of the filter barrel 1 and is fixedly connected to a gear 707. One side of the gear 707 is engaged with the annular teeth 702.

[0028] Working principle: First, pour the material to be separated through the feed shell 11. At this time, turn on the DC motor 701 and cooperate with the first transmission wheel 703 to drive the transmission belt 704 for transmission. At this time, the second transmission wheel 705 will drive the transmission rod 706 to make the gear 707 engage the annular teeth 702 to rotate, so that the centrifugal cylinder 6 rotates and separates. At this time, the centrifugal cylinder 6 will also drive the slide plate 13 to rotate within the internal limit of the annular slide rail 12 to improve its stability. At the same time, the cylinder 14 must be driven to drive the extension rod 15 to descend and drive the sealing plug 16 to seal the position of the slag discharge pipe 10 to prevent the unseparated medium from flowing out. As the centrifugal cylinder 6 rotates, the medium and the water will be diverted, and the liquid will be discharged after being filtered through the filter hole 18 and the precision filter mesh 20 inside the cylindrical filter shell 19. After secondary filtration through the drain pipe 8 and the filter plate 17 inside the filter shell 9, the separated liquid will be discharged, thereby improving the separation and purification effect.
