Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and more specifically, to a pretreatment filtration device for water treatment machinery. Background Technology

[0002] With the rapid development of industry, environmental protection issues have gradually gained attention. Wastewater treatment is one of the important means of environmental protection. When treating wastewater, water treatment machinery is required. Before the wastewater is transported to the interior of the water treatment machinery for purification, a pretreatment filtration device for the water treatment machinery is needed to pre-treat the wastewater.

[0003] Currently, in the pretreatment of wastewater, alum is generally applied manually by workers using tools such as ladles and basins. This allows the alum to pre-treat and filter the wastewater. Although this method can effectively mix the alum with the wastewater, the process of applying alum is time-consuming and labor-intensive. This not only reduces the efficiency of wastewater pretreatment but also increases the workload of workers. Furthermore, manual application of alum can result in uneven application, leading to alum waste and affecting the sedimentation effect of the wastewater.

[0004] Therefore, those skilled in the art have provided a pretreatment filtration device for water treatment machinery to solve the problems mentioned in the background art. Utility Model Content

[0012] As a further improvement to this technical solution, the adjustment assembly includes an adjustment plate fixedly connected between two support frames. A reciprocating motor is fixedly connected to the outside of one of the support frames. The output shaft of the reciprocating motor is fixedly connected to a threaded rod via a coupling. The other end of the threaded rod is rotatably connected to the inner sidewall of the adjustment plate. A threaded plate is threadedly connected to the outside of the threaded rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This pretreatment filtration device for water treatment machinery, through the arrangement of a spray assembly, an adjustment assembly, and a filtration assembly, allows for pretreatment of wastewater.

[0024] 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.

[0025] Please see Figure 1 - Figure 4 As shown, this embodiment provides a pretreatment filtration device for water treatment machinery, including a sewage tank 1, and further comprising:

[0026] Support frames 2 are fixedly connected to both sides of the outer wall of sewage tank 1. Support plates 3 are symmetrically provided on the upper surface of the two support frames 2. Support plates 4 are fixedly connected between multiple support plates 3.

[0027] The spray assembly is positioned above the support plate 4;

[0028] An adjustment component is located between the two support frames 2;

[0029] The suction pipe 26 is located inside the sewage tank 1. The outlet end of the suction pipe 26 is connected to the connecting hose 21. The external part of the suction pipe 26 is fixedly connected to the irregular plate 20.

[0030] The filter assembly is located at the water inlet end of the water suction pipe 26.

[0031] The working principle is as follows: When wastewater pretreatment is required, the wastewater is first added to wastewater tank 1, and then potassium aluminum sulfate solution is added to the spray assembly. The spray assembly then begins operation, effectively spraying the potassium aluminum sulfate solution into wastewater tank 1. This allows the solution to mix effectively with the wastewater, thereby effectively settling impurities in the wastewater. Simultaneously, the regulating component also begins operation, adjusting the horizontal position of the spray assembly to improve the spraying effect and the uniformity of the potassium aluminum sulfate solution spray, thus enhancing the sedimentation effect of the wastewater. The system improves the efficiency and effectiveness of wastewater filtration without requiring manual intervention, thus reducing the workload of staff and enhancing the overall practicality of the device. After the impurities in the wastewater have settled, the outlet end of the connecting hose 21 is connected to the water treatment equipment. At this time, the water treatment equipment will pump the settled wastewater from the wastewater tank 1 into the water treatment equipment for further filtration through the connection between the suction pipe 26 and the connecting hose 21. Through the filter components, the settled impurities in the wastewater tank 1 can be effectively intercepted and filtered, thereby effectively improving the subsequent filtration efficiency and effectiveness of the wastewater and further enhancing the overall practicality of the device.

[0032] To facilitate the convenient and effective spraying of potassium aluminum sulfate solution into the wastewater tank 1, the spraying assembly includes a storage cylinder 5 located above a support plate 4. A fixing frame 6 is fixedly connected to the outside of the storage cylinder 5, and the bottom of the fixing frame 6 is fixedly connected to the upper surface of the support plate 4. A pump 7 is fixedly connected to the upper surface of the support plate 4, and the inlet end of the pump 7 is connected to the bottom of the storage cylinder 5 through a pipe. Spray heads 9 are symmetrically arranged above the wastewater tank 1, and the outlet end of the pump 7 is connected to the inside of the two spray heads 9 through a branch hose 8. When pretreatment of the wastewater inside the wastewater tank 1 is required, the potassium aluminum sulfate solution is first added to the inside of the storage cylinder 5. At this time, the pump 7 starts to run and will transfer the potassium aluminum sulfate solution inside the storage cylinder 5 to the inside of the spray head 9 through the branch hose 8, and then spray it out through the spray head 9. At this time, the potassium aluminum sulfate solution can be sprayed into the inside of the wastewater tank 1 and mixed with the wastewater, thereby causing the impurities contained in the wastewater to precipitate, thus effectively achieving the purpose of wastewater pretreatment.

[0033] Considering that the horizontal position of the spray head 9 needs to be adjusted and moved when spraying potassium aluminum sulfate solution, the adjustment assembly includes an adjustment plate 12 fixedly connected between two support frames 2. A reciprocating motor 13 is fixedly connected to the outside of one of the support frames 2. The output shaft of the reciprocating motor 13 is fixedly connected to a threaded rod 14 via a coupling. The other end of the threaded rod 14 is rotatably connected to the inner wall of the adjustment plate 12. A threaded plate 15 is threadedly connected to the outside of the threaded rod 14. A guide groove for the threaded plate 15 to move is provided at the bottom of the adjustment plate 12. The two spray heads 9 are connected to the threaded plate 15. The spraying components are fixedly connected by connecting rods 16. While the spraying components are running, the reciprocating motor 13 will also start running synchronously. At this time, the reciprocating motor 13 will drive the threaded rod 14 to rotate synchronously, and the threaded plate 15 will move synchronously outside the threaded rod 14, driving the spray head 9 to move synchronously. At this time, the horizontal position of the spray head 9 can be adjusted and moved, so that the spray head 9 can spray the potassium aluminum sulfate solution more comprehensively and evenly, and no manual spraying is required. This effectively improves the sedimentation efficiency and effect of the wastewater and enhances the overall practicality of the device.

[0034] To effectively improve the stability of the spray head 9 during movement, guide rods 10 are symmetrically arranged between the two support frames 2. Guide plates 11 are fixedly connected to the upper surfaces of the two spray heads 9. Guide grooves for the guide rods 10 to move are opened inside the two guide plates 11. During the movement of the spray head 9, the guide plates 11 will also move synchronously outside the guide rods 10. At this time, the guide plates 11 and the guide rods 10 can effectively limit and guide the spray head 9, thereby effectively improving the stability of the spray head 9 during movement.

[0035] To effectively transfer sewage from the sewage tank 1 to the water treatment equipment, one of the support frames 2 is symmetrically equipped with fixing plates 17 on its exterior. Both fixing plates 17 have through holes for mounting electric telescopic rods 18. The telescopic ends of the two electric telescopic rods 18 are fixedly connected to lifting plates 19. The bottom of the lifting plates 19 is fixedly connected to the exterior of the irregular plate 20. When it is necessary to transfer sewage from the sewage tank 1 to the water treatment equipment, simply connect the connecting hose 21 to the water treatment equipment. At this time, the water treatment equipment will transfer the sewage from the sewage tank... The sewage inside the sewage tank 1 is pumped into the water treatment equipment for further filtration through the connection between the suction pipe 26 and the connecting hose 21. When the height of the suction pipe 26 needs to be adjusted, the electric telescopic rod 18 starts to operate. At this time, the electric telescopic rod 18 will drive the lifting plate 19 to move synchronously. The lifting plate 19 will then drive the irregular plate 20 to move synchronously. The irregular plate 20 will then drive the suction pipe 26 to move synchronously. At this time, the height of the suction pipe 26 can be adjusted, so that the suction pipe 26 can effectively transfer the sewage inside the sewage tank 1 to the inside of the water treatment equipment.

[0036] In addition, to prevent sediment from the sewage tank 1 from being transferred to the water treatment equipment, the filter assembly includes a filter membrane 22 fitted over the suction pipe 26. A fixing sleeve 23 is fitted over the filter membrane 22. A first outer plate 24 is symmetrically fitted over the fixing sleeve 23, and a second outer plate 25 is symmetrically fitted over the suction pipe 26. The two first outer plates 24 and the second outer plate 25 are fixedly connected by bolts. When it is necessary to transfer sewage from the sewage tank 1 to the water treatment equipment, simply fit the filter membrane 22 over the suction pipe 26, then fit the fixing sleeve 23 over the filter membrane 22, and then fix the first outer plate 24 and the second outer plate 25 with bolts. This allows the filter membrane 22 and the fixing sleeve 23 to be fixedly installed, thereby intercepting and filtering impurities and sediment in the sewage through the filter membrane 22, effectively improving the subsequent filtration efficiency and effect of the sewage.
