DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts fall within the protection scope of the utility model.

[0026] Please refer to Figures 1-5 The utility model provides the following technical scheme:

[0027] A kind of pneumatic flushing device for water plant filter, including filter pool body 1, filter material 13 and filter plate 14;

[0028] Filter plate 14 is installed in the inside of filter pool body 1, and filter material 13 is stacked above filter plate 14;The lower side of filter pool body 1 is provided with backwashing water pipe, and the backwashing water pipe is the existing conventional technology, further comprising: connecting pipe 10 is installed at the back of filter pool body 1, and the end of connecting pipe 10 close to spoiler 2 is provided with spray pipe 17, and spray pipe 17 is attached to spoiler assembly, and the filter material 13 adsorbed on spoiler assembly is dropped down by the way of attachment, to reduce the loss of filter material 13 particles.

[0029] The filter material 13 and the filter plate 14 filter the sewage in the filter tank body 1, and the filtered water is discharged through the drain. The filter material 13 and the filter plate 14 need to be cleaned regularly. During the flushing process, the air pump 11 makes the gas sprayed out through the spray pipe 17, the gas blows the adsorbed filter material 13 particles on the spoiler 2, and the adsorbed filter material 13 particles fall off, so that the filter material 13 particles return to the original position as much as possible, reducing the loss of filter material 13 particles, and avoiding the uneven thickness of the filter material 13 layer, and the filter material 13 particles do not need to be supplemented regularly.

[0030] The spoiler assembly is arranged in the filter tank body 1, which slows down the floating rate of the filter material 13 particles, which is slower than the suspended impurities. The filter tank body 1 is internally provided with a bevel plate 4, and an electric telescopic rod 3 is installed at the left end of the filter tank body 1, and the output end of the electric telescopic rod 3 is fixed with a comb tooth structure mounting rod 7. The spoiler assembly includes a spoiler plate 2, a guide plate 5, a connecting block 6, and a connecting rod 8. The spoiler plate 2 is connected at equal intervals. The right side of the filter tank body 1 is installed with a connecting block 6, the other end of the connecting block 6 is installed with a guide plate 5, and the guide plate 5 is internally provided with a connecting rod 8. The other end of the connecting rod 8 is fixed with the upper end of the spoiler plate 2. The mounting rod 7 is in contact with the side of the connecting rod 8. The interval between the adjacent two spoiler plates 2 is less than the projection width of a single spoiler plate 2. The rotation angle of the spoiler plate 2 is equal to twice the inclination angle of the spoiler plate 2.

[0031] During the filtering process, the spoiler plate 2 is kept in an inclined structure, which slows down the floating rate of the filter material 13 particles, which is slower than the suspended impurities. Part of the filter material 13 particles settle in place, and part of the filter material 13 particles adhere to the spoiler plate 2. The filter material 13 particles adhere to the lower part of the spoiler plate 2. When it needs to be flushed, the electric telescopic rod 3 operates to move the mounting rod 7 left and right. The movement of the mounting rod 7 pushes the connecting rod 8, which in turn makes the connecting rod 8 slide in the guide plate 5. The guide plate 5 can limit the rotation angle of the spoiler plate 2, so that the spray pipe 17 is completely attached to the side of the spoiler plate 2, and the filter material 13 particles adsorbed on the spoiler plate 2 can be blown off by the gas.

[0032] The one side of the spoiler 2 is attached to the filter material 13 particles, and the water to be filtered enters the V-shaped filter tank, and the one side of the spoiler 2 is washed upwards, so that the filter material 13 particles return in place as much as possible, reduce the loss of filter material 13 particles, and avoid the uneven thickness of the filter material 13 layer. The inside right side of the filter tank body 1 is rotatably connected with a connecting rod 8, and a winding disc 9 is installed on the connecting rod 8. The right end of the mounting rod 7 is inserted into the inside of the penetrating rod 18. The right end of the mounting rod 7 is provided with a groove 19. The inner wall of the penetrating rod 18 is provided with a mounting block 20. The mounting block 20 is inserted into the inside of the groove 19. The inside of the filter tank body 1 is fixedly provided with a limiting rod 15. The limiting rod 15 penetrates the trowel rod 16. The outside of the winding disc 9 is wound with two pull ropes 12 with opposite winding directions. The other ends of the two pull ropes 12 are fixed to the left and right sides of the trowel rod 16.

[0033] The electric telescopic rod 3 moves left and right to drive the mounting rod 7 to move synchronously. The mounting rod 7 moves left and right to drive the groove 19 to move synchronously. Since the groove 19 is provided in a meandering structure, the mounting block 20 rotates around the groove 19. The mounting block 20 drives the penetrating rod 18 to rotate synchronously. The penetrating rod 18 rotates to drive the winding disc 9 to rotate synchronously. The winding disc 9 rotates to realize winding and relaxation of the pull rope 12. One of the winding pull ropes 12 pulls the trowel rod 16. The trowel rod 16 moves left and right to push the filter material 13, so that the top of the filter material 13 is kept flush, avoiding the uneven phenomenon of the filter material 13, and further making the thickness of the filter material 13 uniform.

[0034] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
