[0002] People generate a large amount of sewage in the course of their lives. The definition of sewage is the discharged water from life and production that has been polluted to a certain extent. Water that has lost its original use function is referred to as sewage. When sewage is discharged, it needs to be purified. Direct discharge of untreated domestic sewage will pollute the river environment and is not conducive to environmental protection.

[0003] Existing sewage treatment requires adding sewage treatment agents to the sewage to condense the pollutants in the sewage into flocs or precipitate them, thereby achieving the purpose of purifying the sewage. Usually, there are special pipes responsible for adding sewage treatment agents. After installation, this type of pipe will be used for a long time. Coupled with long-term contact with the sewage treatment agent, it will make it difficult to remove the pipe. When the pipe is blocked, it cannot be properly removed and repaired, causing great trouble for subsequent maintenance.

[0004] At the same time, the injection pipes of the existing pipelines are all located in the same plane, so the injected sewage treatment agents are all in the same plane, which makes it impossible for the sewage at the bottom to contact the sewage treatment agent in the first time, thereby causing the sewage purification to be stratified, and it takes a long time of stirring to allow the sewage to completely react with the sewage treatment liquid, which greatly prolongs the time required for sewage purification and reduces the efficiency of sewage purification.

DETAILED DESCRIPTION

[0037] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0038] Embodiment 1. This embodiment aims to provide a purification device for sewage discharge, which is mainly used for purifying sewage. In view of the problem that the existing sewage treatment agent addition pipeline is difficult to dismantle and repair after long-term use, which affects the later maintenance, and the sewage purification stratification caused by the injection pipes being in the same plane affects the sewage purification efficiency, this embodiment provides a purification device for sewage discharge.

[0039] like Figure 1-8 As shown in the figure, a sewage discharge purification device includes: a purification tank 1, a stirring mechanism 5, a liquid injection mechanism 3 and a filter box 2; the purification tank 1 is a square tank, a square filter port 101 is provided on the front end surface thereof, and a water inlet 102 is provided on the rear end surface thereof, and sewage enters the purification tank through the water inlet 102; a mounting seat 103 is fixed on a side wall of the purification tank 1 by bolts, and support legs 104 are respectively fixed at the four corners below the purification tank 1.

[0040] like Figure 1 and Figure 3 As shown in the figure, the filter box 2 is a box-type structure with an opening on one side, which is connected to the filter port 101, and a vertical downward slot is opened on it. The filter screen 201 is inserted in the slot, and a mounting strip 202 is fixed on the filter screen 201. The size of the mounting strip 202 is larger than the slot. Therefore, when the filter screen 201 is inserted in the slot, the mounting strip 202 overlaps the filter box 2 and is fixed to the filter box 2 by bolts. The bolts are outside the filter box 2 and will not contact the purified water. Therefore, they are not easy to rust, making the disassembly process easier and the filter screen 201 easier to replace. A water outlet 203 is also fixed on the filter box 2, and the purified water that has been processed and filtered will be discharged through the water outlet 203.

[0041] like Figure 1 and Figure 4 As shown in the figure, the injection mechanism 3 includes a water storage pipe 301, a plug 302, a conical head 304 and an injection pipe 305. One end of the water storage pipe 301 is blocked by the plug 302, and a limiting groove 303 is provided on the plug 302. A conical head 304 is fixed to the other end of the water storage pipe 301. A plurality of injection pipes 305 of different lengths extending vertically downward are fixed to the middle of the water storage pipe 301. The sewage treatment agent is mixed with the sewage through the injection pipes 305, and the injection pipes 305 of different lengths can also ensure that the sewage treatment liquid is injected into different layers of the sewage, thereby accelerating the contact reaction between the sewage treatment liquid and the sewage and ensuring the efficiency of sewage purification.

[0042] like Figure 1 and Figure 7 As shown in the figure, the limit seat 6 includes a base 601, a clamping plate 602 and a limit block 603. The base 601 is fixed to a side wall of the purification tank 1 by bolts, and the clamping plate 602 is hinged to the base 601. The clamping plate 602 can rotate and is fixed to the base 601 by bolts.

[0043] like Figure 1 and Figure 8 As shown in FIG. 1 , the docking seat 7 is fixed to the other side wall of the purification tank 1 by bolts, and a conical opening 701 and a threaded opening 702 are provided on the docking seat 7, and the conical opening 701 and the threaded opening 702 are communicated.

When the clamping plate 602 is closed and the limit block 603 is inserted in the limit groove 303, an axial force is generated on the plug 302 due to the extrusion of the inclined surface, and the force is directed toward the docking seat 7. The conical head 304 fixed at the other end of the water storage pipe 301 is tightly pressed against the conical mouth 701 through the axial force, and a sealing gasket is also fixed between the conical head 304 and the conical mouth 701 to prevent water leakage.

One end of the connecting pipe 8 is connected to the water pump 9, and the other end extends out of the water pump box 4 and is threadedly connected to the threaded port 702 on the docking seat 7. The water pump 9 draws the sewage treatment agent into the water storage pipe 301 through the connecting pipe 8, and injects the sewage treatment agent into the sewage through the injection pipe 305.

[0046] like Figure 1 and Figure 6As shown in the figure, the stirring mechanism includes a motor base 501, a driving motor 502, a stirring shaft 503, a stirring plate 504 and a stirring rod 505. Two groups of motor bases 501 are fixed above the purification tank 1 at intervals. A through hole is opened on the motor base 501. The driving motor 502 is fixedly installed on the motor base 501 downward, and the driving shaft thereon passes vertically downward through the through hole. The stirring shaft 503 is fixedly connected to the driving shaft through a coupling. Two square and horizontally arranged stirring plates 504 are fixed on the stirring shaft 503, and a plurality of vertical stirring rods 505 are respectively fixed on the stirring plates 504. The stirring shaft 503 is driven to rotate by the driving motor 502, so that the sewage treatment agent can better contact with the sewage, accelerate the reaction, and increase the efficiency of sewage purification.

[0047] The water storage pipe 301 mentioned in this embodiment is the pipe for adding sewage treatment agent described in the background technology. In this embodiment, the water storage pipe 301 is limited and squeezed by the limit block 603 on the limit seat 6, so that the conical head 304 can be firmly against the conical mouth 701, and a sealing gasket is arranged to prevent water leakage. When dismantling, it is only necessary to open the clamping plate 602 of the limit seat 6 to dismantle the water storage pipe 301 for cleaning or maintenance. At the same time, multiple injection pipes 305 of different lengths are fixed in the middle of the water storage pipe 301, so that different levels of sewage can be injected with sewage treatment agent, thereby improving the purification quality of sewage, saving the time required for purification, and enhancing the efficiency of sewage purification.

[0048] The implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model.
