Specifically, a clamping groove is formed in the connecting rod 220, a clamping block matched with the clamping groove is arranged on the sealing block 230, the clamping block can slide up and down within a preset range defined by the clamping groove, and the sealing block 230 is always attached to the filter screen 200 while sliding. When the side edge of the filter screen 200 rotates from top to bottom, the sealing block 230 is driven to move downwards, so that the sealing block 230 is compressed by the filter screen 200 and the connecting rod 220, the sealing effect of the sealing block 230 is improved, when the side edge of the filter screen 200 rotates from bottom to top, the sealing block 230 is driven to move upwards, the pressure between the sealing block 230 and the filter screen 200 is reduced, the resistance of the sealing block 230 to the rotation of the filter screen 200 is further reduced, and the friction and abrasion of the sealing block 230 are reduced.
In this embodiment, the slag removing mechanism includes a packing auger 310, a rotating shaft of the packing auger 310 is parallel to an axis of the filter screen 200, and blades of the packing auger 310 are attached to a lower side of an inner ring of the filter screen 200, so that impurities on the lower side of the inner ring of the filter screen 200 can be pushed to horizontally move outside the filter screen 200 when the packing auger 310 rotates.

In this embodiment, the second gear 440 is matched with the gear shaft of the auger 310 through a one-way bearing, so that the first gear 430 drives the auger 310 to rotate only when rotating along one direction through the second gear 440, and the impurity is prevented from being driven to reciprocate when the auger 310 rotates reciprocally, and the impurity discharge is prevented from being influenced. Specifically, the filter screen 200 can reciprocate along the first direction and the second direction, and when the filter screen 200 rotates along the first direction, the water blocking plate 210 is driven to move to the first side, and when the filter screen 200 rotates along the second direction, the water blocking plate 210 is driven to move to the second side, wherein the first side and the second side are two sides of the axial direction of the filter screen 200. Because the vane of the packing auger 310 and the filter screen 200 are rotated in opposite directions, the packing auger 310 pushes the impurity to move to the first side when rotating along the first direction, and pushes the impurity to move to the second side when rotating along the second direction, and the first gear 430 drives the second gear 440 to rotate when rotating along the first direction or the second direction, so that the moving direction of the water blocking plate 210 is opposite to the direction in which the packing auger 310 pushes the impurity to move, and the impurity on the lower side of the inner ring of the filter screen 200 is accelerated to be discharged.
In this embodiment, the support 100 includes a chassis 110 and a housing 120, the housing 120 is fixedly mounted on the chassis 110, the filter screen 200 and the cleaning mechanism are both mounted in the housing 120, a water collecting bin 121 and a slag collecting bin 122 separated by a baffle 125 are disposed at the bottom of the housing 120, the baffle 125 is vertically disposed, and a rotation hole allowing the auger 310 to rotate is formed in the baffle 125. The water collection bin 121 is used for receiving water filtered by the filter screen 200, and the slag collection bin 122 is used for receiving impurities cleaned by the cleaning mechanism. When the first gear 430 rotates along the first direction and can drive the second gear 440 to rotate along the second direction, the slag collecting bin 122 is located on the second side of the housing 120, and when the first gear 430 rotates along the second direction and can drive the second gear 440 to rotate along the first direction, the slag collecting bin 122 is located on the first side of the housing 120. The side wall of the bottom of the water collection bin 121 is provided with a water outlet 126 which allows filtered water to be discharged; the bottom of the slag collecting bin 122 is of a filter screen structure, so that sewage entering the slag collecting bin 122 through the rotating holes is discharged through the bottom of the slag collecting bin 122; and the bottom of the slag collecting bin 122 is communicated with the water collecting bin 121, so that water entering the slag collecting bin 122 returns to the water collecting bin 121 again. The inner wall of the slag collecting bin 122 is attached to the outer edge of the blade of the auger 310, and the side wall of the slag collecting bin 122 is provided with a slag discharging port allowing the cleaned impurities to be discharged, so that the auger 310 can conveniently discharge the cleaned impurities.
In this embodiment, the casing 120 is provided with a water inlet 123, and the water inlet 123 is located above the filter screen 200; the casing 120 is provided with a water guide plate 124, and different flow channels are formed on the water guide plate 124 to guide water flow entering through the water inlet 123 to flow downwards from the upper parts of different positions of the filter screen 200.
In this embodiment, the housing 120 is a split structure that is detachable from top to bottom, and two parts of the housing 120 are detachable at the position of the connecting rod 220, so as to facilitate replacement of the sealing block 230.
When the filtering device for the environment-friendly hydraulic engineering is used, the motor is started to drive the filter screen 200 to rotate in a reciprocating mode, sewage is introduced into the shell 120 from the water inlet 123, and the water guide plate 124 guides the sewage to flow downwards from the upper parts of different positions of the filter screen 200. Part of sewage enters the inner ring of the filter screen 200 from the space between the two spiral structures of the filter screen 200 for filtering, and part of water flows enter the inner ring of the filter screen 200 through the filter screen 200 and is backflushed to the lower side of the inner ring of the filter screen 200 against impurities attached to the upper side of the inner surface of the filter screen 200. When the filter screen 200 rotates, the sealing block 230 intercepts impurities on the outer surface of the filter screen 200, and the filter screen 200 drives the water shutoff plate 210 and the connecting rod 220 to reciprocate in the horizontal direction while rotating reciprocally, so that the impurities intercepted by the sealing block 230 drop to the inner ring of the filter screen 200 from between two adjacent spiral structures of the filter screen 200. Auger 310 conveys impurities in the opposite direction to filter screen 200 when filter screen 200 rotates in the first direction or the second direction, cleans impurities accumulated on the lower side of the inner ring of filter screen 200, reduces the frequency of blockage of filter screen 200, and enables the filtration work to be continuously performed.
