Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a sewage filtering device. Background Art

[0002] With the continuous development of society, people's quality of life and the development of industrial production have improved rapidly. The various daily sewage and industrial sewage generated will cause serious pollution to water bodies and soil if discharged directly. Therefore, sewage needs to be purified before discharge to ensure that it can be effectively filtered and meet the discharge standards.

[0003] According to a sewage filtration device disclosed in the Chinese patent document with the announcement number CN218011436U, a problem that the physical sewage filtration device on the market in the prior art solves the problem that during use, after a long period of use, some aquatic organisms or debris will inevitably remain on the surface of the screen, so that after the device has been used for a period of time, personnel need to clean the screen inside the device. The cleaning process is time-consuming and labor-intensive, and there are places that personnel cannot reach, leaving dead corners for cleaning, which increases the workload of personnel. A sewage filtration device includes a shell, and a cover plate is rotatably connected to one side of the upper surface of the shell. The utility model changes the traditional method in which personnel use a handheld device to clean debris adsorbed on the screen, and also avoids the problem of dead corners that cannot be cleaned, ensuring that the screen is cleaned neatly, reducing the workload of personnel, and improving the actual use efficiency of the device.

[0004] Based on the search of the above patents and in combination with the filtering devices in the prior art, it was found that the above device, when in use, can deal with dead corners that cannot be cleaned. During the cleaning process, the bidirectional screw and the brush need to cooperate for cleaning. However, in actual use, since the screw is in a humid environment for a long time, the bidirectional screw will be corroded and damaged, and the screw sleeve cannot be moved, which will lead to poor cleaning effect or unusable. In addition, during filtering, the sewage cannot be graded and filtered, which will cause some fine impurities to follow the water flow and flow away from the aperture of the screen, resulting in poor sewage filtration effect, thereby reducing practicality. Utility Model Content

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0033] like Figures 1 to 5As shown, a sewage filtering device provided by an embodiment of the present invention includes a filter box 1, an upper end surface of the filter box 1 is provided with a mounting groove 11, a fixed plate 12 is movably connected in the mounting groove 11, and a first filter plate 13, a second filter plate 14 and a third filter plate 15 are fixedly connected to the lower end surface of the fixed plate 12, respectively. A plurality of evenly distributed first filter holes 51, a second filter hole 52 and a third filter hole 53 are respectively provided on the first filter plate 13, the second filter plate 14 and the third filter plate 15, and the inner diameters of the first filter hole 51, the second filter hole 52 and the third filter hole 53 decrease in sequence. By using the first filter plate 13, the second filter plate 14 and the third filter plate 15, impurities in the sewage can be graded and filtered to improve the efficiency. The sewage filtration effect is achieved by fixing the upper end surface of the fixed plate 12 with two symmetrical retaining blocks 16, a locking hole 17 is provided on one side of the retaining block 16, a locking column 18 is movably connected in the locking hole 17, and a movable plate 19 is fixedly connected between the two locking columns 18. The side of the movable plate 19 away from the retaining block 16 is fixedly connected with two symmetrical moving rods 20, and a stabilizing block 21 is slidably connected between the two moving rods 20. The outer surface of the moving rod 20 is provided with a spring 22, and the two ends of the spring 22 are fixedly connected to the moving plate 19 and the stabilizing block 21 respectively. In cooperation with the movement of the moving block, the moving block moves with the two locking columns 18 in the direction of the stabilizing block 21, so that the two moving rods 20 slide on the stabilizing block 21, squeezing the two springs 22, and The locking post 18 is quickly disengaged from the locking hole 17, which facilitates the disassembly and cleaning of the fixed plate 12, the first filter plate 13, the second filter plate 14 and the third filter plate 15. The movable plate 19 is fixedly connected to the retaining plate 31 on the side away from the retaining block 16. The retaining plate 31 is slidably connected to the stabilizing block 21. The retaining plate 31 is slidably connected with the insertion rod 32. The upper end surface of the filter box 1 is provided with a slot 33. The insertion rod 32 is movably connected to the slot 33. The outer wall of the insertion rod 32 is fixedly connected to the limiting ring 34. The movement of the movable plate 19 can move the retaining plate 31, and the insertion rod 32 on the retaining plate 31 is connected to the slot 33 on the filter box 1. The retaining plate 31 can be fixed to ensure that the movable plate 19 and the two locking posts 18 will not move at will. The filter box 1 is provided with a guide groove 41 on the upper end surface, and a guide block 42 is slidably connected in the guide groove 41. The guide block 42 is fixedly connected to the movable plate 19. The use of the guide groove 41 and the guide block 42 can guide the movable plate 19 to ensure that the movable plate 19 is sufficiently stable during the movement. Two symmetrical connecting grooves 61 are provided on the inner walls on both sides of the filter box 1. A connecting rod 62 is movably connected in the connecting groove 61. The connecting rod 62 is fixedly connected to the fixed plate 12. Through the four connecting rods 62, the fixed plate 12 and the filter box 1 can be quickly connected to prevent the impact of water flow from causing skewness. A water inlet pipe 71 is fixedly connected to one side of the filter box 1, and a water inlet valve 72 is fixedly connected to the water inlet pipe 71.A water outlet pipe 81 is fixedly connected to the side of the filter box 1 away from the water inlet pipe 71. A drain valve 82 is fixedly connected to the water outlet pipe 81. The water inlet pipe 71 and the water outlet pipe 81 can transport sewage into the filter box 1 and discharge filtered water. The water inlet valve 72 and the drain valve 82 can control the opening and closing of the water inlet pipe 71 and the water outlet pipe 81 respectively.

[0034] The working principle and use process of the present invention are as follows: when in use, first, sewage is transported to the filter box 1 through the water inlet pipe 71, and the impurities contained in the sewage are filtered in sequence through the first filter plate 13, the second filter plate 14 and the third filter plate 15. The impurities of different sizes contained in the sewage can be graded and filtered through the first filter hole 51, the second filter hole 52 and the third filter hole 53. After the first filter plate 13, the second filter plate 14 and the third filter plate 15 have been used for a period of time, the water inlet pipe 71 is closed through the water inlet valve 72, and the movable plate 19 is moved so that the movable plate 19 is disengaged from the locking hole 17 with the two locking columns 18. As the movable plate 19 moves, the retaining plate 31 moves along with it, carrying the insertion rod 32 to move in the direction of the slot 33, so that the insertion rod 32 is docked with the slot 33, and then the movable plate 19 and the locking column 18 are fixed, and the fixed plate 12 is taken out. The impurities on the surfaces of the first filter plate 13, the second filter plate 14 and the third filter plate 15 are cleaned. After cleaning, the four connecting rods 62 are aligned with their corresponding connecting grooves 61 to preliminarily connect the fixed plate 12 to the filter box 1, and the two springs 22 are rebounded with the withdrawal of the insertion rod 32, so that the two locking columns 18 quickly lock the fixed plate 12, thereby realizing the use process of the entire sewage filtering device.
