This utility model is very convenient and quick to clean the filtered dirt, effectively reducing the cleaning difficulty. Furthermore, the entire cleaning process does not require stopping the equipment, thus effectively improving the efficiency of wastewater treatment.

[0004] Although the above technical solutions achieve continuous filtration of wastewater, there are a lot of suspended solids and particles in the wastewater. The suspended solids and particles adhering to the filter cylinder wall will reduce the filtration efficiency of the wastewater. Manually cleaning the suspended solids on the filter cylinder wall is labor-intensive and increases the workload of the staff. The automatic cleaning effect of the device is also poor. Therefore, we need to propose a chemical wastewater purification device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a chemical wastewater purification device, including a base 1, two sets of support seats 2 are provided on the upper surface of the base 1, wastewater purification mechanisms 3 are symmetrically arranged on the two sets of support seats 2, valve assemblies 6 are provided on the wastewater purification mechanisms 3, and two sets of support mechanisms 4 are provided on the base 1.

[0023] The wastewater purification mechanism 3 includes a wastewater tank 31. An inlet cone pipe 35 is provided on one side of the wastewater tank 31, and a drain pipe 38 is connected to the inlet cone pipe 35. An outlet cone pipe 36 is provided on the other side of the wastewater tank 31, and a backwash pipe 39 is connected to the outlet cone pipe 36. A limit ring 33 is provided on one side of the inner cavity of the wastewater tank 31, and a filter cylinder 34 is locked inside the limit ring 33. A sealing plate 37 that abuts against one end of the filter cylinder 34 is fixedly connected to the inner cavity of the outlet cone pipe 36. A sewage inlet hole 32 that communicates with the inner cavity of the filter cylinder 34 is opened on one side of the wastewater tank 31.

[0024] The valve assembly 6 includes a first inlet valve 61, a first outlet valve 62, a second inlet valve 64, and a second outlet valve 63. The first inlet valve 61 is installed at the inlet end of the inlet cone pipe 35, the first outlet valve 62 is installed at the inlet end of the drain pipe 38, the second outlet valve 63 is installed at the outlet end of the outlet cone pipe 36, and the second inlet valve 64 is installed at the outlet end of the backwash pipe 39. By alternating the opening and closing of the first inlet valve 61, the first outlet valve 62, the second inlet valve 64, and the second outlet valve 63, the filtration and purification of wastewater and the cleaning of the filter cartridge 34 can be facilitated, thus improving practicality.

[0025] The inlet end of the inlet cone pipe 35 and the outlet end of the drain pipe 38 are both connected to the wastewater tank. The outlet end of the outlet cone pipe 36 and the inlet end of the backwash pipe 39 are both connected to the clean water tank. The backwash pipe 39 facilitates the flow of clean water into the wastewater tank 31 to rinse the filter cartridge 34, thereby improving the cleaning effect of the filter cartridge 34.

[0026] The outer diameter of the inlet cone 35 is smaller than that of the outlet cone 36, and the inner diameter of the inlet cone 35 is the same as that of the sewage inlet 32. Since the inlet is smaller than the outlet, the purification effect of wastewater is improved, and the service life of the filter cartridge 34 is increased, avoiding damage to the filter cartridge 34 due to excessive water flow impact pressure.

[0027] The support mechanism 4 includes a support plate 41. A connecting ring is provided on the upper surface of the support plate 41, and an adjusting screw 42 that passes through the base 1 is rotatably provided inside the connecting ring. A handwheel 44 is fixedly connected to the upper end of the adjusting screw 42. By driving the handwheel 44, the position of the adjusting screw 42 relative to the support plate 41 is adjusted, which improves the convenience of overall movement of the device and its stability at a designated location.

[0028] The upper surface of the base 1 is provided with screw holes for the installation of the adjusting screw 42. Both ends of the upper surface of the support plate 41 are fixedly connected with telescopic rods 43. The upper end of the telescopic rod 43 is fixedly connected to the lower surface of the base 1. The telescopic rod 43 improves the stability of the base 1 after the support plate 41 touches the ground and the moving wheel 5 leaves the ground.

[0029] Multiple sets of casters 5 are installed on the lower surface of the base 1. The casters 5 are arranged in a rectangular array. The length of the adjusting screw 42 is greater than the height of the casters 5. The casters 5 facilitate the movement of the purification device, thereby improving the convenience of moving the purification device.

[0030] In use, chemical wastewater in the wastewater tank is introduced into the wastewater tank 31 through the inlet cone pipe 35. The filter cartridge 34 is used to filter and purify the suspended solids and particulate matter in the wastewater. The filtered and purified water is then discharged into the clean water tank through the outlet cone pipe 36. At this time, the first inlet valve 61 and the second outlet valve 63 are open, while the first outlet valve 62 and the second inlet valve 64 are closed, thus performing rapid filtration and purification of the sewage.

[0031] When the filter cartridge 34 needs to be cleaned, the first inlet valve 61 and the second outlet valve 63 are closed while the first outlet valve 62 and the second inlet valve 64 are opened. This allows clean water to flow through the backwash pipe 39 into the inlet cone pipe 35, and then into the wastewater tank 31. The clean water enters the inner cavity of the filter cartridge 34 from the outside to the inside, thereby washing away suspended solids and particulate impurities on the inner wall of the filter cartridge 34. The washed-out impurities flow back into the wastewater pool through the drain pipe 38. The two sets of wastewater purification mechanisms 3 need to stagger their backwashing times to ensure continuous and effective filtration and purification of wastewater, improve wastewater treatment efficiency, avoid manual cleaning, and reduce the workload of staff.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
