Description

Technical Field

[0001] This utility model relates to the field of sewage filter residue cleaning technology, and in particular to a sewage filtration device that automatically cleans filter residue. Background Technology

[0002] When coarse screens filter wastewater, some impurities that would normally pass through the mesh are trapped inside due to the flow of water. This not only affects the filtration efficiency but also the cleaning efficiency. Chinese Patent CN219333321U discloses a wastewater filtration device that is easy to clean. Specifically, it discloses a motor that, through the cooperation of a slide, slider, moving cavity, and screw, moves the filter box to the left, allowing it to move to the outside of the treatment tank through the cleaning port. When the filter box passes the fixed crossbar, an impact block, in cooperation with the mounting hole, telescopic rod, and spring, strikes the inside of the coarse filter holes, pushing the impurities trapped inside upwards. Although this can push out the impurities from the screen, it takes a long time to push out one row at a time, and the screen has multiple rows of coarse filter holes, resulting in low cleaning efficiency. Therefore, there is an urgent need for a wastewater filtration device that can automatically clean the filter residue and solve the problems of long cleaning time and low cleaning efficiency.

[0027] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0028] Please refer to Figures 1 to 3 A wastewater filtration device for automatically cleaning filter residue, comprising:

[0029] The filter box 1 is connected to the bottom by a support column 11. The top of the filter box 1 is provided with a water inlet 12 and a drain pipe 13. The inner wall of one side of the filter box 1 is provided with a first limiting groove 14, the opening of the first limiting groove facing the inside of the filter box 1. The inner wall of the other side of the filter box 1 is provided with a second limiting groove 15, the opening of the second limiting groove 15 facing the first limiting groove 14.

[0030] The first cylinder 2 is connected to the outer wall of the filter box 1 on the X-direction side, and the cylinder body axis of the first cylinder 2 is vertical.

[0031] The second cylinder 3 is connected to the outer wall of the filter box 1 on the opposite side of the X direction, and the second cylinder 3 is parallel to the first cylinder 2.

[0032] The first filter plate 4 has a plurality of first filter holes 41. The lower part of the first filter plate 4 has a plurality of first unblocking rods 42. The first unblocking rods 42 are located between two adjacent filter holes. The axis of the first unblocking rods 42 is vertical. The first filter plate 4 has a first slider 43 on one side and a second slider 44 on the other side. The first slider 43 is connected to the piston rod of the first cylinder 2, and the second slider 44 is connected to the piston rod of the second cylinder 3.

[0033] The second filter plate 5 is connected inside the filter box 1. The second filter plate 5 is located below the first limiting groove 14. The second filter plate 5 is provided with a plurality of second filter holes 51 that match the first unblocking rod 42. The upper part of the second filter plate 5 is provided with a plurality of second unblocking rods 52 that match the first filter holes 41. The axial direction of the second unblocking rods 52 is vertical. The radius of the second filter holes 51 is smaller than that of the first filter holes 41.

[0034] In the above embodiments, wastewater is poured into the filter box 1 through the inlet 12. The wastewater passes through the first filter hole 41 of the first filter plate 4 and the second filter hole 51 of the second filter plate 5. The filtered wastewater is discharged through the drain pipe 13 at the top of the filter box 1. When it is necessary to clean the first filter hole 41 of the first filter plate 4 and the second filter hole 51 of the second filter plate 5, the first drive motor 64 is turned on. The first cylinder 2 and the second cylinder 3 drive the first slider 43 and the second slider 44 to move downward, thereby causing the first filter plate 4 to move downward. The first unblocking rod of the first filter plate 4 pushes out the impurities of the second filter plate 5, and the second unblocking rod 52 of the second filter plate 5 pushes out the impurities of the first filter plate 4, thereby preventing the first filter plate 4 and the second filter plate 5 from clogging, thus ensuring the filtration efficiency of wastewater. Compared with the prior art, it can be cleaned in one go, saving time and improving efficiency.

[0035] As an optional implementation, the wastewater filtration device for automatically cleaning filter residue also includes a cleaning device 6. The cleaning device 6 includes a scraper 61, a third slider 62, a screw 63, a drive motor 64, and a limiting rod 65. A sludge collection box 7 is provided on the side wall of the filter box 1, and a feed inlet 71 is provided on the side wall of the sludge collection box 7. The feed inlet 71 communicates with the filter box 1 and is located above the second limiting groove 15. One end of the screw 63 is connected to the inner wall of the filter box 1 on the X-direction side, and the other end of the screw 63 is connected to the inner wall of the sludge treatment box on the X-direction side. The axial direction is X-direction. The limiting rod 65 is parallel to the second screw 63. One end of the limiting rod 65 is connected to the inner wall of the filter box 1 in the X-direction direction, and the other end of the limiting rod 65 is connected to the inner wall of the impurity treatment box in the X-direction direction. The third slider 62 is slidably connected to the second screw 63 and the limiting rod 65. The lower part of the third slider 62 is provided with a scraper 61. The lower part of the scraper 61 is flush with the feed port 71. The drive motor 64 is connected to the outer wall of the filter box 1 and is connected to the screw 63 in a transmission connection. In a certain state, the lower part of the scraper 61 abuts against the upper part of the first filter plate 4.

[0036] In the above embodiments, when it is necessary to clean the impurities on the first filter plate 4, the first cylinder 2 and the second cylinder drive the first slider 43 and the second slider 44 to move upward, so that the first filter plate 4 moves along the direction, so that the upper part of the first filter plate 4 abuts against the lower part of the scraper 61. Then the drive motor 64 is turned on, and the drive motor 64 drives the screw 63 to rotate, so that the scraper 61 scrapes the impurities on the first filter plate 4 into the impurity collection box 7.

[0037] As an optional implementation, a plurality of springs 8 are provided between the third slider 62 and the scraper 61, with the axis of the springs 8 being vertical.

[0038] In the above embodiments, by providing the spring 8, the scraper 61 can always be pressed against the first filter plate 4, thereby scraping the impurities on the first filter plate 4 into the impurity collection box 7.

[0039] As an optional implementation, the bottom side wall of the filter box 1 is provided with a hinged first door 16, and the bottom side wall of the impurity collection box 7 in the X direction is provided with a hinged second door 72.

[0040] In the above embodiments, by setting the first door 16, impurities in the impurity collection box 7 can be cleaned.

[0041] As an optional implementation, the bottom sidewall of the impurity collection box 7 in the X direction is provided with a hinged second box door 72.

[0042] In the above embodiments, a second door 72 is provided to clean the impurities pushed out of the second filter plate 5 by the first unblocking rod 42.
