In addition, the driving assembly 110 includes a base plate 111, a servo motor 112 is disposed on one side of the top end of the base plate 111, the sealing assembly 120 includes an inner attachment ring 121, a plurality of connecting rods 122 are connected to the side of the inner attachment ring 121, a threaded ring 123 is connected between the ends of the connecting rods 122, the connecting assembly 130 includes a rotating ring 131, one side of the rotating ring 131 is connected to the side of the threaded ring 123, a plurality of insertion rods 132 are disposed on the other side of the rotating ring 131, a fixing ring 133 is disposed at the end of the insertion rod 132, a plurality of sleeves 134 are disposed at positions of the fixing ring 133 close to one side of the insertion rod 132, each sleeve 134 is respectively matched with each insertion rod 132 in an insertion manner, and the other side of the fixing ring 133 is fixedly connected to the side of the servo motor 112. During specific use, the tail end of the servo motor 112 is coaxially connected with the tail end of the connecting column 215, the servo motor 112 drives the inner chamber 210 to rotate through the connecting column 215, the rotating ring 131 slides in the position adjusting process of the connecting assembly 130, and the tail end of the inserted rod 132 freely slides along the inner end of the sleeve column 134, so that the length between the inserted rod 132 and the sleeve column 134 is freely changed, the tail end of the sealing assembly 120 is driven to freely enter and exit from the inner end of the through groove 233, and the function of freely opening or closing the inner end of the through groove 233 is achieved.

In the process that the base plate 111 drives the inner chamber 210 to rotate, the whole filtering device 20 is supported only through the connecting column 215, the connecting column 215 is required to bear all weight, meanwhile, the connecting column 215 is required to rotate at a high speed, the connecting column 215 is easily stressed too much, so that the connecting column 215 is broken, and the service life of the connecting column 215 is influenced, further, the driving assembly 110 further comprises an arc-shaped support plate 113, clamping rods 114 are arranged at two ends of the side surface of the arc-shaped support plate 113, the clamping rods 114 are of a U-shaped structure, two sides of each clamping rod 114 are respectively attached to two sides of the drainage outer ring 230, at the moment, the bottom end of the drainage outer ring 230 is lifted through the arc-shaped support plate 113 and the clamping rods 114, the normal rotation of the filtering device 20 is guaranteed, the pressure borne by the connecting column 215 is shared through the arc-shaped support plate 113 and the clamping rods 114, the burden of the connecting column 215 is reduced, and the service life of the connecting column 215 is prolonged.

Further, the end portions of the two sides of the clamping rod 114 are provided with two attachment plates 115, and the two attachment plates 115 are respectively attached to the two sides of the outer drainage ring 230. When the filter device is used specifically, the friction resistance generated by the contact surface of the clamping rod 114 and the drainage outer ring 230 is reduced through the arranged attachment plate 115, the energy consumption lost in the rotation process of the filter device 20 is reduced, and the kinetic energy utilization rate of the servo motor 112 is improved.

Because at the discharge of carrying out prefiltering sewage and sewage filter residue discharge process, prefiltering sewage and sewage filter residue receive centrifugal force effect to have partly to get rid of to coupling assembling 130 inboardly, long-term in the past, filter residue and prefiltering sewage accumulate very easily and collect together at coupling assembling 130 inboardly, need operating personnel regularly to clear up coupling assembling 130 inboardly, it is specific, a plurality of inner arc grooves 1131 have been seted up to arc extension board 113 inboard, the small opening has been seted up to coupling assembling 130 inboard intermediate position, the small opening runs through each inner arc groove 1131, the filter residue carries out the drainage through the inner arc groove 1131 that sets up to adhesion at the inboard prefiltering sewage of coupling assembling 130 and sewage filter residue this moment and handles, with prefiltering sewage and sewage drainage to small opening, coupling assembling 130 bottom is discharged through the small opening, need not operating personnel to carry out the secondary and clear up, alleviate operating personnel work load.

In addition, a plurality of clamping blocks are arranged at the tail end of the inserting rod 132, a plurality of clamping grooves are formed in the outer side of the sleeve column 134, and the clamping blocks are in sliding connection with the clamping grooves. During the specific use, inject coupling assembling 130 flexible length through draw-in groove and the fixture block that sets up to can inject the inner degree of depth of sealing component 120 insertion logical groove 233, avoid sealing component 120 to insert logical groove 233 inner too deeply, lead to sealing component 120 to lead to logical groove 233 inner to extrude.

Furthermore, a plurality of inserting columns 124 are inserted and matched at the edge position of the side surface of the sealing component 120, the inserting columns 124 are arranged in an array, and the tail ends of the inserting columns 124 are connected with return springs. When the tail end of the sealing assembly 120 extends into the inner end of the through groove 233 during specific use, the tail end of the sealing assembly 120 is in contact with the tail end of the through groove 233, the tail end of each inserting column 124 is in contact with the inner end of the through groove 233 in advance, the inserting columns 124 are subjected to pressure generated by the inner end of the through groove 233, the inserting columns 124 reversely push the return springs, the return springs contract and the pressure generated by the tail end of the sealing assembly 120 is applied to the inner end of the through groove 233, loss caused to the inner end of the through groove 233 is further reduced, and the service life of the drainage outer ring 230 is prolonged.

Still further, the outer side of the sealing component 120 is provided with a groove, the inner end of the groove is connected with a plurality of balls 125 in a rolling manner, and the top end of each ball 125 is connected with the inner wall of the through groove 233 in a rolling manner.
