[0020] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0021] like Figure 1-4As shown, a fly ash leaching solution treatment device for a waste incineration power plant includes a filter box 1. The top of the filter box 1 is fixedly connected to a sealing cover 2 by bolts. A cleaning mechanism 3 is provided on the top of the sealing cover 2. A filter screen 4 is provided inside the filter box 1. One side of the filter box 1 is connected to a water inlet pipe 5.

[0022] A disinfection box is provided on one side of the filter box 1 , and a water pump is provided between the filter box 1 and the disinfection box. The pumping end of the water pump is connected to one side of the filter box 1 , and the drainage end of the water pump is connected to one side of the disinfection box.

[0023] The sewage enters the filter box 1 from the water inlet pipe 5, and the impurities in the sewage are filtered through the filter 4. Then, the sewage is transported to the disinfection box by a water pump for disinfection.

[0024] like Figure 1-Figure 4 As shown, the cleaning mechanism 3 includes an air pump 31 fixed to one side of the sealing cover 2, and an electric cylinder 32 is provided on the other side of the sealing cover 2. The air outlet end of the air pump 31 is connected to a hose 33, and the output end of the electric cylinder 32 passes through the bottom of the sealing cover 2 and is fixedly connected to a hollow plate 34. One end of the hose 33 is connected to the top of the hollow plate 34, and one side of the hollow plate 34 is connected to a nozzle 35. The bottom of the hollow plate 34 is fixedly connected to a mounting plate 36 through a fixing block, and a brush 37 is provided inside the mounting plate 36.

[0025] The number of the nozzles 35 is set to be several, and the nozzles 35 are arranged at equal intervals.

[0026] Among them, the air pump 31 and the electric cylinder 32 are started, and the air pump 31 transports the gas to the hollow plate 34 through the hose 33, and finally sprays it out from the multiple nozzles 35, which can blow out some impurities stuck in the mesh. The electric cylinder 32 drives the hollow plate 34 to move, and when the hollow plate 34 moves, it can drive the mounting plate 36 to move, so that the nozzle 35 and the brush 37 can move up and down at the same time, thereby cleaning the filter 4 and improving the cleaning effect.

[0027] like Figure 3 and Figure 4 As shown, the inner wall of the mounting plate 36 is slidably connected to an arc-shaped block 6, one side of the arc-shaped block 6 is fixedly connected to a spring 7, one end of the spring 7 is fixedly connected to the inner wall of the mounting plate 36, one side of the arc-shaped block 6 is fixedly connected to a slider 8, and one side of the brush 37 is provided with an arc-shaped slot 9, and the arc-shaped block 6 is engaged with the arc-shaped slot 9.

[0028] A sliding groove is formed on the inner wall of the mounting plate 36 , and the slider 8 is slidably connected to the sliding groove.

[0029] When the brush 37 needs to be replaced, the sealing cover 2 is removed from the filter box 1, and then the brush 37 is pulled to make the arc-shaped slot 9 squeeze the arc-shaped block 6. The arc-shaped block 6 is squeezed to drive the slider 8 to move and retract into the mounting plate 36. At this time, the spring 7 is in a compressed state, and then the brush 37 can be removed from the mounting plate 36 by continuing to pull it. The operation is convenient.

[0030] like Figure 1 and Figure 2 As shown, a through slot 10 is provided on one side of the filter box 1, and a sealing plate 11 is fixedly connected to the inner wall of the through slot 10 by bolts. A mounting rail 12 is fixedly connected to the inner wall of the filter box 1, and the mounting rail 12 is slidably connected to the filter screen 4. The inner wall of the mounting rail 12 is threadedly connected with a hand screw 13.

[0031] Among them, the sealing plate 11 is removed from the through groove 10, and impurities in the filter box 1 are collected through the through groove 10. The restriction on the filter screen 4 can be released by turning the hand screw 13, so that the filter screen 4 can be taken out from the installation track 12 for easy replacement.

[0032] The working principle of the present invention is as follows: start the air pump 31 and the electric cylinder 32, the air pump 31 delivers gas to the hollow plate 34 and sprays it out from the nozzle 35, which can blow out impurities stuck in the mesh, and the electric cylinder 32 drives the nozzle 35 and the brush 37 to move up and down, thereby cleaning the filter 4 and improving the cleaning effect.
