[0002] In the existing chemical and food industry production, the requirements for liquid quality are very high. It is usually necessary to remove impurities in the liquid through a filter. Generally, filter elements with different pore sizes are used to filter the liquid to achieve the purpose of purifying the liquid.

[0003] Among the existing equipment, the filter screen or filter element for filtering liquid is generally fixed in the shell. After a certain period of use, the shell needs to be disassembled to remove the filter component from the inside and then clean it. The shell and the cover plate are generally fixed by several bolts and other components, which makes it difficult to disassemble and separate the two to remove the filter element, which is not conducive to improving its scope of application.

[0017] The following are examples and the attached Figure 1-2 , the technical solution of the present invention is further specifically described.

[0018] A filter structure includes a cylindrical shell 1, wherein a cover plate is provided on the top of the shell 1, and a water inlet pipe 2 and a water outlet pipe 3 are respectively provided on both sides of the shell, and the water inlet pipe 2 and the water outlet pipe 3 are respectively provided on the top of the two side walls of the shell 1:

[0019] The inner wall of the shell 1 on both sides of the water inlet pipe 2 and the water outlet pipe 3 is axially provided with a stop bar 4, and the straight line formed by the water inlet pipe 2 and the water outlet pipe 3 divides the shell 1 into two groups of filter chambers 5, wherein each group of filter chambers 5 is provided with multiple groups of filter plates 6, and the aperture of the filter plate 6 located at the upstream of any two adjacent groups of filter plates 6 is larger than the aperture of the filter plate 6 at the downstream, and one end of each filter plate 6 is connected to the rotating shaft 7 in the middle of the shell 1, wherein the rotating shaft 7 is driven by the motor 8 on the cover plate;

[0020] A rectangular box body 9 connected to the middle of the bottom of the shell 1 is also provided below the shell 1, wherein a sewage pipe 10 is provided on the side wall of the box body 9, and a sealing block 11 is also provided in the box body 9, wherein a screw 13 is fixed to the bottom of the sealing block 11 through a bearing 12, and the screw 13 passes through a screw tube 14 at the bottom of the box body 9, and the screw 13 is screwed and fixed to the screw tube 14, wherein a protrusion is provided at the bottom end of the screw 13.

[0021] In this embodiment, the size of the sealing block 11 is adapted to the size of the internal opening of the box body 9, wherein the sealing block 11 is located above the sewage pipe 10, and the top of the sealing block 11 is flush with the inner bottom wall of the shell 1, and the thickness of the sealing block 11 is not greater than the depth of the box body 9 below the sewage pipe 10.

[0022] In this embodiment, one end of the filter plate 6 is fixedly connected to the rotating shaft 7 , wherein the other end of the filter plate 6 abuts against the inner wall of the housing 1 , and any two adjacent groups of filter plates 6 are connected via an arc rod 15 .

[0023] The method of use of the present invention is as follows: liquid enters the shell 1 through the water inlet pipe 2 and is discharged from the water outlet pipe 3 by the two groups of filter chamber flows 5, wherein the liquid is filtered by multiple groups of filter plates 6 with different apertures in the filter chamber 5, thereby filtering impurities in the liquid. When cleaning the impurities in the shell 1, the motor 8 drives the rotating shaft 7 to drive the multiple groups of filter plates 6 to reciprocate. At this time, the baffle 4 can limit the rotation amplitude of the filter plate 6, thereby stirring the liquid in the shell 1 to generate an impact force, so that the fluctuating liquid has a flushing effect on the impurities adhered to the side wall of the filter plate 6 and the inner wall of the shell 1, thereby separating the impurities adhered to the filter plate 6 and the inner wall of the shell 1 from them and mixing with the liquid. At the same time, the rotating screw 13 drives the sealing block 11 to slide downward in the box body 9 to the bottom of the sewage pipe 10, and then the sewage pipe 10 is opened to allow the liquid mixed with impurities in the shell 1 to be discharged through the box body 9 and the sewage pipe 10, so that the impurities filtered inside the shell 1 can be cleaned without opening the shell 1.

[0024] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
