Figure 4A partial cross-sectional structure schematic view at the first sleeve and the second sleeve provided by the embodiment of the present application. The microporous folded filter element 100 comprises a filter element body 110, which can be arranged by referring to the prior art. The filter element body 110 is uniformly provided with filter holes, which can block solid impurities from passing through to achieve the filtering effect. The bottom of the filter element body 110 is connected with a circular bottom plate 120, which is sealingly connected between the filter element body 110, so as to ensure that the liquid to be filtered in the filter element body 110 cannot leak through the gap between the filter element body 110 and the bottom plate 120. The top of the filter element body 110 is open, and the top of the filter element body 110 is fixedly connected with a bellows 130. The bellows 130 has good tensile property and can be elongated in the process of rising with the installation ring 140, and the bellows 130 is contracted and reset in the process of falling of the installation ring 140, so as to be able to reduce the deformation of the filter element body 110. It should be noted that the bellows 130 does not have filter holes and thus does not have filtering effect. The top of the bellows 130 is fixedly connected with the installation ring 140, and the installation ring 140 is also sealingly connected with the bellows 130. The installation ring 140 can be connected with the reciprocating extrusion assembly, and then is lifted or falls under the driving of the reciprocating extrusion assembly. The bottom of the installation ring 140 is connected with a plurality of spiral baffles 141 on the inner side of the bellows 130. The plurality of baffles 141 are arranged at intervals along the circumference of the installation ring 140, and have gaps between adjacent two baffles 141. The baffles 141 are used for causing disturbance to the liquid to be filtered in the filter element body 110, so as to form a spiral vortex by limiting the flow direction of the liquid and making the liquid flow along the side wall of the baffle 141 when passing through the gap between the baffles 141. The top of the bottom plate 120 is fixedly provided with a first sleeve 121, which is located on the inner side of the bellows 130. The top of the first sleeve 121 is sleeved with a second sleeve 142, and the top side wall of the second sleeve 142 is fixedly connected to the inner side wall of the plurality of baffles 141. In the process of upward and downward reciprocating movement of the installation ring 140, since the second sleeve 142 is connected to the installation ring 140 through the baffles 141, the baffles 141 and the second sleeve 142 will move upward and downward synchronously with the installation ring 140. In this process, the first sleeve 121 and the second sleeve 142 slide relative to each other, and the position of the first sleeve 121 does not change. The top of the installation ring 140 is provided with a cover plate 150, which is sealingly connected to the installation ring 140. The top of the cover plate 150 is penetratingly provided with a water inlet pipe 151, which is used for conveying the liquid to be filtered into the inside of the filter element body 110. The water inlet pipe 151 can be arranged by referring to the prior art, and it is well known that a corresponding valve body is arranged at the water inlet pipe 151.The top of the mounting ring 140 is provided with a connecting port 160 for connecting with a reciprocating extrusion member, which can be in the form of a hydraulic cylinder, a pneumatic cylinder or a telescopic rod, etc., and is used to drive the mounting ring 140 to move up and down to extrude the liquid to be filtered in the filter element body 110 to quickly complete the filtration.

[0021] As can be seen from the above, in the embodiment of the present application, through the cooperation of the first sleeve 121, the second sleeve 142, the spoiler 141 and the mounting ring 140, when the mounting ring 140 is driven to move downward by the externally connected reciprocating extrusion member, the second sleeve 142 and the spoiler 141 fall synchronously to extrude the liquid to be filtered in the filter element body 110, and the liquid to be filtered will pass through the gap between the adjacent two spoilers 141 in the moving process, thereby forming a spiral vortex, so as to wash away the solid particles at the filter holes to a certain extent to avoid the blockage of the filter holes, and further, to slow down the speed of the solid particles blocking the filter holes during the filtration process, thereby prolonging the cleaning cycle of the filter element. The first sleeve 121 and the second sleeve 142 which are mutually sleeved have a certain limiting effect to make the mounting ring 140 more stable during the up and down reciprocating movement.

[0022] In some embodiments, the top end of the mounting ring 140 is provided with an annular groove 143, and a sealing rubber ring 143a is arranged in the annular groove 143. A plurality of opposite reserved holes are arranged at the mounting ring 140 and the cover plate 150 respectively along the axial direction, and a screw 144 is connected in the opposite two reserved holes. In the embodiment of the present application, when the screw 144 is tightened, the mounting ring 140 and the cover plate 150 will tightly press and extrude the sealing rubber ring 143a, thereby improving the sealing performance of the cover plate 150 and the mounting ring 140.

[0023] In some embodiments, there are two annular grooves 143 which are coaxially arranged, and correspondingly, there are two sealing rubber rings 143a. In the embodiment of the present application, through the arrangement of the two annular grooves 143 and the sealing rubber rings 143a, the sealing performance of the mounting ring 140 and the cover plate 150 can be further improved.

[0024] In some embodiments, four ear plates 145 are arranged on the outer periphery of the mounting ring 140, and the four ear plates 145 are arranged at equal intervals along the axial direction of the mounting ring 140. Two vertical plates 161 which are parallel to each other are fixed above the ear plates 145. In the embodiment of the present application, the reciprocating extrusion member connected externally can be connected to the mounting ring 140 through the two vertical plates 161 which are arranged in parallel, and of course, the reciprocating extrusion member is four and simultaneously uniformly acts on the four peripheries of the mounting ring 140, thereby making the stress on the mounting ring 140 more uniform and stable.

[0025] In some embodiments, the spoiler 141 is tapered away from one end of the mounting ring 140 to form a smooth end 141a and abut against the outer sidewall of the second sleeve 142. In the embodiments of the present application, the bottom end of the spoiler 141 is minimized and abuts against the second sleeve 142 by the above arrangement, thereby avoiding scratching the corrugated pipe 130 or the filter element body 110 during movement of the mounting ring 140.

[0026] In some embodiments, a plurality of strip-shaped sliding rails 142a are vertically formed on the inner sidewall of the second sleeve 142, and the strip-shaped sliding rails 142a are arranged at intervals along the circumference of the second sleeve 142. The outer sidewall of the first sleeve 121 is provided with a plurality of strip-shaped protrusions 121a corresponding to the sliding rails 142a, and the strip-shaped protrusions 121a are slidably connected inside the sliding rails 142a. In the embodiments of the present application, the sliding rails 142a and the strip-shaped protrusions 121a are arranged between the first sleeve 121 and the second sleeve 142, thereby further ensuring the stability of the first sleeve 121 and the second sleeve 142 during relative sliding.

[0027] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the above embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
