The implementation principle of the environment-friendly sludge treatment equipment for the hydraulic engineering is as follows:

after the sludge passes through the upper filter plate 11, large solid particle impurities in the sludge are intercepted. The sludge falls to the surface of the sliding filter plate 33. When the sludge stays on the surface of the sliding filter plate 33, the water contained in the inside thereof falls through the lower filter plate 12. Sludge stays between the upper filter plate 11 and the lower filter plate 12 to carry out draining operation.

After the sludge on the surface of the sliding filter plate 33 is gradually increased, the sludge gradually overcomes the gravity of the first spring 32 and presses the sliding filter plate 33 to move downwards. The abutting rod 61 moves to the side close to the sliding filter plate 33 under the action of the second spring 63. The connecting tube 52 follows the abutting rod 61.

The insert ring 51 in the connecting rod is separated from the insert I44 and the insert II 45 in the initial state. After the sleeve 5 moves along with the abutting rod 61, the insert ring 51 is inserted into the insert piece II 45, so that the connecting pipe 52 rotates along with the gear I24. The connecting pipe 52 drives the screw rod 54 to move in the rotating process, and the two pressing plates 3 move oppositely to extrude the moisture in the sludge.

After a part of water in the sludge is drained, the sliding filter plate 33 moves upwards under the action of the first spring 32. The sleeve 5 is separated from the second inserting piece 45, and the screw rod 54 stops rotating. After the surface of the sliding filter plate 33 continues to accumulate a certain amount of sludge, the sliding filter plate 33 continues to move downward.

After the sludge is drained, the sludge leaves the sliding filter plate 33, and the sliding filter plate 33 is lifted completely under the action of the elastic force. At this time, the insert ring 51 is inserted into the insert piece 44, the connecting pipe 52 rotates in the opposite direction, and the screw 54 drives the pressing plate 3 to move to the side away from the sliding filter plate 33.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
