[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0032] Example 1

[0033] like Figures 1-5 As shown, the present invention provides a technical solution: a membrane filter with a centrifugal structure, including a filter tank 1, a telescopic mechanism 2 fixedly connected to the top of the outer surface of the filter tank 1, a butterfly plate 3 fixedly connected to the output end of the telescopic mechanism 2, a material feeding device 4 provided at the top of the filter tank 1, a membrane filter 5 fixedly connected inside the filter tank 1, a slag discharge device 6 provided at the bottom of the inner surface of the membrane filter 5, an anti-adhesion device 7 provided at the top of the filter tank 1 and near the membrane filter 5, an inlet 8 fixedly connected to the top of the filter tank 1, and an outlet 9 fixedly connected to the bottom of the filter tank 1.

[0034] The feeding device 4 includes a threaded sleeve 41. The outer surface of the threaded sleeve 41 is fixedly connected to the top of the filter tank 1. The inner surface of the threaded sleeve 41 is threadedly connected to a threaded drive column 42. The top of the threaded drive column 42 is fixedly connected to a rotary connector 43. The top of the rotary connector 43 is fixedly connected to the bottom of the butterfly plate 3. The bottom end of the threaded drive column 42 is fixedly connected to a conical disk 44. The outer surface of the conical disk 44 is fixedly connected to a crescent plate 45. The bottom of the conical disk 44 is fixedly connected to a centrifugal device 46.

[0035] The bottom of the membrane filter 5 penetrates the bottom of the inner surface of the filter tank 1 and extends to the outside. The crescent-shaped plates 45 are set at an angle and are evenly distributed on the outer surface of the conical disk 44.

[0036] The fluid to be filtered is injected into the filter tank 1 through inlet 8. The extension and contraction of the telescopic mechanism 2, along with the butterfly plate 3, drives the feeding device 4 to move up and down reciprocally. The threaded drive column 42 and threaded sleeve 41 are connected by a thread, and the rotation of the rotating connector 43 causes the threaded drive column 42 to not only drive the conical disc 44 and centrifugal device 46 to move reciprocally, but also to cause the crescent plate 45 and centrifugal device 46 to rotate rapidly. The rotating crescent plate 45 evenly distributes the fluid, causing it to be sprayed out by centrifugal force, promoting its distribution into the membrane filter 5 for filtration. Simultaneously, the reciprocating movement of the centrifugal device 46 causes the slag discharge device 6 to be subjected to force, and the anti-adhesion device 7 also moves reciprocally with the drive of the butterfly plate 3, effectively preventing impurities from adhering to the inner surface of the membrane filter 5, thus facilitating the discharge of the filtered slag.

[0037] The centrifugal device 46 includes a connecting rod 461, the top end of which is fixedly connected to the bottom end of the conical disk 44. A forked blade 462 is fixedly connected to the outer surface of the connecting rod 461, and a receiving plate 463 is fixedly connected to the outer surface of the forked blade 462. A leakage hole 464 is provided on the outer surface of the receiving plate 463.

[0038] The outer surfaces of the forked blade 462 and the receiving secondary blade 463 are both set as arc-shaped surfaces, and the forked blade 462 is evenly distributed on the outer surface of the connecting pressure rod 461.

[0039] When the connecting pressure rod 461 is driven to rotate by the threaded drive column 42, the forked blade 462 and the receiving plate 463 also rotate together. At this time, the rotation of the forked blade 462 removes the impurities attached to the inner surface of the membrane filter 5 in time, and the fluid falls onto the receiving plate 463 to slow down the flow of the fluid. Under the action of rotation, the fluid is subjected to centrifugal force again, and some fluid passes through the leakage hole 464, so that the fluid can be mixed evenly and promote the filtration of the fluid.

[0044] When the centrifugal device 46 is driven to move downward as a whole, the pressure slide rod 62 is pressed downward by the bottom end of the connecting pressure rod 461, and the reset part 63 is compressed, at this time, the edge of the cutting wheel piece 642 is attached to the bottom of the inner surface of the membrane filter 5, and under the action of rolling, the impurities adhering to the bottom of the inner surface of the membrane filter 5 are cut, thereby reducing the adhesion of the impurities, and as the pressure slide rod 62 is continuously pressed, the swing connecting rod 641 drives the slag cutting blade 644 to rotate, thereby cutting the impurities accumulated together at the bottom of the membrane filter 5, and as the pressure on the pressure slide rod 62 disappears, the pressure slide rod 62 drives the puncture device 64 to move upward as a whole under the action of the elastic force of the reset part 63, at this time, the puncture strip 643 punctures the impurities about to be deposited, so that the impurities are not easy to deposit, thereby facilitating the treatment of the impurities and avoiding the blockage.
