It uses a variety of technical means such as filtration and sedimentation, and can effectively remove impurities and pollutants from wastewater, especially when treating wastewater with multiple pollutants, so as to achieve the purpose of purifying water quality.

[0003] When in use, the purification equipment treats wastewater. It is equipped with a filter to filter out sediment and solid pollutants in the wastewater. However, as the wastewater is continuously purified, too much sediment and solid pollutants will accumulate on the filter. The presence of these impurities will cause the filter to become clogged and affect its normal use, which will lead to a decrease in the purification efficiency of the wastewater.

[0004] Therefore, a multi-layer wastewater purification device for multiple pollutants is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where filter clogging affects subsequent purification efficiency as wastewater purification time increases, and to propose a multi-layer wastewater purification device for multiple pollutants.

A waste discharge pipe is connected to one side of the top of the cylinder.

[0017] Compared with the prior art, this utility model provides a multi-layer wastewater purification device for multiple pollutants, which has the following beneficial effects:

[0018] 1. This utility model uses the cam rotation to strike the actuating plate, causing the actuating plate to reciprocate on the filter screen, thereby striking the filter screen. This causes the contaminants attached to the filter screen to detach from the filter screen due to inertia, preventing a large amount of contaminants from accumulating on the filter screen, causing filter screen blockage, and thus affecting subsequent filtration operations.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Please see Figures 1 to 4 A multi-layer wastewater purification device for multiple pollutants includes a purification box 1 with an opening at the top, an inlet 2 installed at the top of one end of the purification box 1, and a drain outlet 3 installed at the top of the other end of the purification box 1.

[0028] Inside the purification chamber 1, there are multiple filter screens 6 arranged along the length of the purification chamber 1. The mesh size of the multiple filter screens 6 increases sequentially from the inlet 2 to the outlet 3, so that after the wastewater enters the purification chamber 1 from the inlet 2, it undergoes multiple filtration operations and performs graded filtration of pollutants of different particle sizes, so that pollutants of different particle sizes do not concentrate on a certain filter screen 6, thereby preventing the filter screen 6 from becoming clogged prematurely.

[0029] The filter 6 is installed inside the fixed frame 4, and the fixed frame 4 is detachably fixed to the inner wall of the purification box 1. For example... Figure 1 and Figure 2 As shown, a limiting seat 5 is provided along the edge of the fixed frame 4, so that the fixed frame 4 is placed in the limiting seat 5. The limiting seat 5 is fixed to the inner wall of the purification box 1, that is, the limiting seat 5 is fixedly installed along the inner wall of the purification box 1, and the fixed frame 4 is placed in the limiting seat 5 for limiting placement. In this way, the filter screen 6 can be installed in the purification box 1 by plugging and unplugging along with the fixed frame 4, which facilitates the installation and removal of the filter screen 6. In actual use, in order to improve the stability of the filter screen 6 in the purification box 1, the fixed frame 4 and the purification box 1 or the fixed frame 4 and the limiting seat 5 can be fastened with bolts.

[0030] like Figure 1 and Figure 3 As shown, a flap 18 is provided in the middle of the side of each filter screen 6 away from the water inlet 2. A connecting rod 17 is installed on the top of the flap 18, and the other end of the connecting rod 17 is fixed to the rotating seat 9. A rotating shaft 10 is connected to both ends of the rotating seat 9. The other end of the rotating shaft 10 is rotatably mounted on the fixed seat 11, and the fixed seat 11 is fixed to the strip plate 7. The strip plate 7 is placed above the fixed frame 4 and its two ends are connected to the support mechanism. The support mechanism includes two rods fixed to the outer sides of the purification box 1. The slide rail 21 on the wall has a slider 20 corresponding to the strip plate 7, and a connecting bracket 19 is installed on the slider 20. The connecting bracket 19 is fixed to the end of the strip plate 7, so that the strip plate 7 can slide on the top of the purification box 1 to adjust the distance between the tapping plate 18 and the filter screen 6. In actual use, when the filter screen 6 needs to be replaced, the tapping plate 18 can be moved away from the filter screen 6, so as to facilitate the removal and installation of the filter screen 6 and will not obstruct the removal and installation of the filter screen 6 due to the setting of the tapping plate 18.

[0031] When the plate 18 approaches the filter screen 6, in order to stabilize the position of the plate 18, a locking bolt 22 is threadedly connected to the connecting frame 19. The end of the locking bolt 22 corresponds to the outer wall of the purification box 1. The locking bolt 22 can be turned to press the end of the locking bolt 22 against the outer wall of the purification box 1, thereby fixing the strip plate 7 and preventing the strip plate 7 from sliding accidentally.

[0032] When purifying wastewater, a slot 8 corresponding to the rotating seat 9 is opened on the strip plate 7. A toggle plate 13 is installed on the top of the rotating seat 9, and the toggle plate 13 is set through the slot 8. A cam 14 is provided on one side of the toggle plate 13. A drive shaft is coaxially installed on the cam 14. One end of the drive shaft is rotatably installed on the strip plate 7, and the other end is installed with a first drive motor 15. The first drive motor 15 is set in a motor housing 16, which is fixed to the strip plate 7 by a bracket. The first drive motor 15 drives the cam 14 to rotate, so that the cam 14 acts on the toggle plate 13 when rotating, so that the beater 18 can reciprocate on the filter screen 6, thereby beating the filter screen 6 and making the filter screen 6 vibrate. This allows the pollutants attached to the filter screen 6 to be removed from the filter screen 6 under the action of vibration and inertia, thereby reducing the accumulation of pollutants on the filter screen 6 and the situation where the filter screen 6 is blocked, affecting subsequent filtration operations.

[0033] It should be noted that a torsion spring 12 is sleeved on the rotating shaft 10. One end of the torsion spring 12 is fixed on the fixed seat 11, and the other end of the torsion spring 12 is fixed on the rotating seat 9. It provides elastic force for the reciprocating deflection of the clapper 18, strengthens the reciprocating motion of the clapper 18, and improves the beating effect of the clapper 18 on the filter screen 6.

[0034] After the pollutants settle on the bottom of the purification chamber 1, such as Figure 3 and Figure 4 As shown, a flow guide seat 23 is installed on the bottom of the purification box 1. The top surface of the flow guide seat 23 is tilted towards one side of the purification box 1. The pollutants falling at the bottom of the purification box 1 will slide along the flow guide seat 23 to the bottom of the flow guide seat 23.

[0035] Furthermore, a cylindrical tube 24 with a bottom opening is provided on the side of the filter screen 6. The cylindrical tube 24 is fixed to the inner wall of the purification box 1 by a bracket, and the bottom of the cylindrical tube 24 corresponds to the bottom of the guide seat 23. A spiral conveying shaft 25 is provided inside the cylindrical tube 24. The bottom of the spiral conveying shaft 25 is rotatably mounted on a fixed frame 26, and the end of the fixed frame 26 is fixed to the inner wall of the cylindrical tube 24. The top of the spiral conveying shaft 25 passes through the top of the cylindrical tube 24 and is connected to a second drive motor 27. The second drive motor 27 is fixed on the cylindrical tube 24, and the top of the spiral conveying shaft 25 is rotatably connected to the cylindrical tube 24. A waste discharge pipe 28 is connected to one side of the top of the cylindrical tube 24. Under the operation of the spiral conveying shaft 25, pollutants deposited on the bottom of the guide seat 23 can be drawn into the cylindrical tube 24 and discharged from the waste discharge pipe 28. This allows for timely discharge of pollutants deposited at the bottom of the purification box 1, preventing the accumulation of pollutants in the purification box 1.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
