[0022] The following will be combined with the appendix Figure 1 To be continued Figure 5 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0023] This utility model provides a replaceable sewage treatment device for environmental engineering, including a small box 1, an inlet pipe 2 fixedly installed on the top of the small box 1, an outlet pipe 3 fixedly installed on the outside of the small box 1, a filter assembly inside the small box 1, and a descaling assembly inside the small box 1 and above the filter assembly.
[0024] The filter assembly includes a filter plate 4, grooves 5, slots 6, cavities 7, a first sliding plate 8, a sliding rod 9, a compression spring 10, a sliding groove 11, a fixing plate 12, a two-way lead screw 13, a second sliding plate 14, a turntable 15, a torsion spring 16, a locking block 17, and a locking groove 18. The grooves 5 are equidistantly located on one side of the inner wall of the small housing 1. The slots 6 are equidistantly located on the side of the small housing 1 away from the grooves 5. The filter plates 4 pass through the interior of the grooves 5 and extend into the interior of the slots 6. Two cavities 7 are equidistantly located inside the inner wall of the small housing 1 and are situated on either side of the slots 6. Two sliding grooves 11 are equidistantly located on the outer side of the small housing 1. The interiors of the cavities 7 and the sliding grooves 11 are interconnected. Both slide rods 9 are fixedly installed inside the cavity 7. The first slide plate 8 is slidably connected to the outer side between the two slide rods 9. Compression springs 10 are fixedly installed between the outer side of the first slide plate 8 and one side of the inner wall of the cavity 7. Slots 18 are opened on both sides of one end of the filter plate 4. Slots 17 are fixedly installed on the inner side of the first slide plate 8. The end of the slot 17 away from the first slide plate 8 extends into the inside of the slot 18. Two fixing plates 12 are fixedly installed equidistantly on the outer side of the small box 1 and located on both sides of the two slide grooves 11. A bidirectional lead screw 13 is rotatably connected between the two fixing plates 12. A turntable 15 is fixedly installed on one end of the bidirectional lead screw 13 and extends to one of the fixing plates 12. On the outside, the second slide plate 14 is threaded to the outside of both ends of the double-acting screw 13. The end of the second slide plate 14 away from the double-acting screw 13 passes through the inside of the slide groove 11 and is fixedly connected to one side of the first slide plate 8. The torsion spring 16 is fixedly installed between the outside of one of the fixed plates 12 and the inside of the turntable 15 and is located outside the double-acting screw 13. By manually rotating the turntable 15, the double-acting screw 13 is driven to rotate between the two fixed plates 12, and at the same time, the torsion spring 16 is driven to twist, thereby causing the two second slide plates 14 to slide in opposite directions on both ends of the double-acting screw 13, and in turn, causing the two first slide plates 8 to slide in opposite directions between the outside of the two slide rods 9. The sliding motion causes the two compression springs 10 to deform, simultaneously pulling the locking block 17 on the inner side of the first sliding plate 8 to separate from the locking grooves 18 on both sides of one end of the filter plate 4. Then, the filter plate 4 is pulled out from the slot 6 and the groove 5 in sequence. After releasing the turntable 15, the structure is reset by utilizing the characteristics of the torsion spring 16 and the compression spring 10. This enables the filter plate 4 to be quickly disassembled and replaced, preventing the filter plate 4 from becoming damp and rusty due to installation with bolts and nuts, thus reducing the difficulty of disassembling and replacing the filter plate 4, further improving work efficiency, increasing the practicality of the equipment, and facilitating practical application and operation.
[0025] Furthermore, the solid waste removal component includes a screen plate 21, guide plates 22, and a discharge port 23. The discharge port 23 is located on one side of the inner wall of the small box 1 and above the groove 5. The screen plate 21 is fixedly installed inside the small box 1 and above the discharge port 23. The guide plates 22 are fixedly installed on both sides of the top of the screen plate 21. Wastewater is injected into the screen plate 21 inside the small box 1 through the inside of the inlet pipe 2 to filter solid waste in the wastewater. Then, with the help of the two guide plates 22 and the inclination of the screen plate 21 itself, the solid waste is discharged and removed from the inside of the discharge port 23, achieving the effect of primary filtration.
[0026] Furthermore, a through groove 27 is provided on the outer side of the small housing 1 and below the motor 19. A filling cylinder 24 is fixedly installed on the outer side of the small housing 1 and near the through groove 27. A piston 25 is slidably connected inside the filling cylinder 24. A connecting pipe 28 is fixedly installed at one end of the filling cylinder 24. The end of the connecting pipe 28 away from the filling cylinder 24 extends into the through groove 27. A one-way valve 29 is fixedly installed inside one end of the connecting pipe 28. A T-shaped push rod 26 is fixedly installed on the side of the piston 25 away from the connecting pipe 28. The end of the T-shaped push rod 26 away from the piston 25 extends to the outer side of the filling cylinder 24. By pressing the T-shaped push rod 26, the piston 25 inside the filling cylinder 24 slides from left to right, so that the polyaluminum chloride in the filling cylinder 24 is squeezed from the inside of the filling cylinder 24 into the inside of the small housing 1 through the one-way valve 29 in the connecting pipe 28, so that the polyaluminum chloride can be used in combination with purified water to purify the water source.
[0027] Furthermore, a screw rod 20 is rotatably connected between the inner walls of the small box 1 and below the filter plate 4. A motor 19 is fixedly installed on the outer side of the small box 1 and below the filter plate 4. The output shaft of the motor 19 extends into the interior of the small box 1 and is fixedly connected to one end of the screw rod 20. By driving the motor 19, the screw rod 20 inside the small box 1 is rotated, which facilitates the mixing and stirring of the purified water source with polyaluminum chloride to achieve the final purification operation. It also facilitates the outlet of the purified water source from the inside of the outlet pipe 3 to the outside of the small box 1.
[0028] Furthermore, the motor 19 is electrically connected to the external control panel, and the four corners of the bottom of the small housing 1 are provided with housing legs. By providing housing legs, it is convenient to stably support the small housing 1. By providing electrical connection, it is convenient to quickly drive the equipment.
[0029] The working principle of this utility model is as follows: First, by pressing the T-shaped push rod 26, the piston 25 inside the filling cylinder 24 slides from left to right, causing the polyaluminum chloride inside the filling cylinder 24 to be squeezed from inside the filling cylinder 24 into the small box 1 through the one-way valve 29 in the connecting pipe 28. Then, the water inlet pipe 2 at the top of the small box 1 is threadedly connected to the external sewage pipe. Then, the sewage is injected into the screen plate 21 inside the small box 1 through the water inlet pipe 2 to filter solid waste in the sewage. This is then combined with two guide plates 22. Solid waste is discharged and removed from the inside of the discharge port 23, achieving the effect of initial filtration. Then, the three filter plates 4, made of activated carbon, ion exchange resin, and coral sand respectively, further filter the water after the initial purification. Simultaneously, the drive motor 19 rotates the screw rod 20 inside the small box 1, facilitating the mixing and stirring of the purified water with polyaluminum chloride for final purification. This also facilitates the discharge of the purified water from the inside of the outlet pipe 3 to the outside of the small box 1, achieving wastewater purification. When the equipment is turned off and the filter plates 4 inside the small box 1 need to be replaced, the turntable 15 is manually rotated, causing the bidirectional screw 13 to rotate between the two fixed plates 12. This simultaneously causes the torsion spring 16 to twist, thereby causing the two second sliding plates 14 to slide back and forth on both ends of the bidirectional screw 13. This, in turn, causes the two first sliding plates 8 to slide back and forth between the outer sides of the two sliding rods 9, causing the two compression springs 10 to deform. At the same time, the locking blocks 17 on the inner side of the first sliding plates 8 move out of the slots 1 on both sides of one end of the filter plate 4. Separate the filter plate 4 from the slot 6 and groove 5 in sequence. After releasing the turntable 15, the structure is reset by using the characteristics of the torsion spring 16 and compression spring 10. This allows for quick disassembly and replacement of the filter plate 4. Conversely, the reverse operation is for installation. This prevents the filter plate 4 from becoming damp and rusty due to installation with bolts and nuts, which would make it difficult to disassemble. This reduces the difficulty of disassembling and replacing the filter plate 4, further improves work efficiency, increases the practicality of the equipment, and is beneficial for practical application and operation.
[0030] Based on the explanations and teachings in the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and any modifications and alterations to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
