[0018] Reference Figures 1 to 5 The utility model is further described in detail.

[0019] A desilting device for a water conservancy project comprises a working box 1, a first filtering mechanism 2, a second filtering mechanism 3, a filter element 10 and a guide plate 9. The first filtering mechanism 2 and the second filtering mechanism 3 are respectively placed on the working box 1, and the second filtering mechanism 3 is placed below the first filtering mechanism 2. The first filtering mechanism 2 and the second filtering mechanism 3 are respectively movably connected to the working box 1. The guide plate 9 is fixed to the working box 1 in an inclined state. A water outlet groove 8 is opened on one side of the working box 1. The filter element 10 is movably connected to the working box 1 and placed in the water outlet groove 8.

[0020] The first filtering mechanism 2 includes a storage shell 21, a filter screen 22, a handle 23, an annular plate 24 and a fixing rod 25. The storage shell 21 is placed in the working box 1. A limiting groove 4 is formed on the storage shell 21. The filter screen 22 is fixed in the limiting groove 4. The annular plate 24 is fixedly connected to the storage shell 21. The fixing rod 25 is fixed on the annular plate 24. A positioning hole 5 corresponding to the fixing rod 25 is formed on the working box 1. The fixing rod 25 extends into the positioning hole 5, and the annular plate 24 is in conflict with the working box 1. The handle 23 is fixed on the annular plate 24.

[0021] By pouring the water with sludge into the working box 1, the water, impurities and solid waste in the sludge can be effectively separated. The first filter mechanism 2 realizes preliminary filtration through the filter net 22, and the second filter mechanism 3 further performs fine filtration on the water filtered by the first filter mechanism 2, thereby improving the filtration effect. At the same time, the first filter mechanism 2 and the second filter mechanism 3 are movably connected, so that the first filter mechanism 2 and the second filter mechanism 3 can be removed from the working box 1, and then cleaned to increase the service life.

[0022] The second filtering mechanism 3 includes a handle 31, a connecting plate 32, a limiting plate 33 and a rubber sleeve 34. The connecting plate 32 is placed in the working box 1 and has a plurality of filtering holes 6. The limiting plate 33 is L-shaped and fixed to both ends of the inner wall of the working box 1. Both ends of the connecting plate 32 have connecting grooves 7, and the limiting plate 33 extends into the connecting grooves 7. The handle 31 is fixed to the connecting plate 32. The rubber sleeve 34 is sleeved on the connecting plate 32 and contacts the inner wall of the working box 1.

[0023] The water filtered by the first filter mechanism 2 flows into the connecting plate 32, and the water with sludge is further filtered through the filter hole 6, thereby improving the filtering effect. At the same time, the connecting plate 32 is fixed in the working box 1 by clamping the limiting plate 33 with the upper connecting groove 7 of the connecting plate 32. At the same time, the rubber sleeve 34 is sleeved on the connecting plate 32 and contacts the inner wall of the working box 1 to achieve a sealing effect. At the same time, after the first filter mechanism 2 is taken out from the working box 1, the connecting plate 32 is driven to move by grasping the handle 31 and moving upward, and then the limiting plate 33 is separated from the connecting groove 7, and then the handle 31 drives the connecting plate 32 to be taken out of the working box 1 for cleaning, thereby improving the service life.

[0024] The filter element 10 includes a filter plate 101, a connection frame 102 and a protrusion 103. The connection frame 102 is detachably connected to the working box 1 and is placed in the water outlet tank 8. The filter plate 101 is fixed in the connection frame 102. The protrusion 103 is fixed at both ends of the connection frame 102. A groove 11 corresponding to the protrusion 103 is opened on the inner wall of the water outlet tank 8, and the protrusion 103 is placed in the groove 11.

[0025] The water flows into the water outlet trough 8 through the drainage plate, and then is filtered for the third time through the filter plate 101, thereby further improving the filtering effect of the water. At the same time, the connection frame 102 is disassembled and connected to the working box 1 so that the connection frame 102 can be taken out of the water outlet trough 8, and then the filter plate 101 in the connection frame 102 can be cleaned, thereby increasing the service life.

[0026] Working principle: First, pour the water with impurities into the working box 1, the water first enters the storage shell 21 and is initially filtered through the filter screen 22, the stones and debris in the water are accumulated on the filter screen 22, and then the water that has been filtered once flows into the connecting plate 32, and then the silt in the water is separated from the water through the filter hole 6 on the connecting plate 32, the silt is placed on the connecting plate 32, the water flows to the guide plate 9 through the filter hole 6, and then the water is filtered twice, and then the water that has been filtered twice flows through the guide plate 9 to the water outlet 8, and then passes through the filter plate 101 for the third time, and then the water that has been filtered three times flows out of the water outlet 8. When the filtering work is completed, an upward force is applied to the handle 23, and then the handle 23 drives The annular plate 24 moves, and then the fixing rods 25 of the annular plate 24 are respectively moved out of the positioning holes 5. At the same time, the annular plate 24 drives the storage shell 21 to move, and then the storage shell 21 is taken out of the working box 1, and then the debris placed on the filter screen 22 is poured out and the storage shell 21 is cleaned. At this time, the second filter mechanism 3 is exposed, and by holding the handle 31 and applying an upward force thereto, the handle 31 drives the connecting plate 32 to move until the connecting plate 32 is taken out of the working box 1, and then the sludge on the connecting plate 32 is cleaned, and finally the connecting frame 102 is pulled out of the water outlet 8 and the filter plate 101 is cleaned, and then the first filter mechanism 2, the second filter mechanism 3 and the filter element 10 are all cleaned, thereby improving the service life.
