Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment devices, in particular to a multi-stage sedimentation biological decomposition and purification sewage treatment device. Background Art
[0002] Sewage refers to the discharged water from life and production that is polluted to a certain extent. It is mainly the water used in life. It contains more organic matter and is relatively easy to treat. In order to avoid direct discharge of sewage to pollute the environment, it is necessary to carry out sedimentation, filtration and purification before the sewage is discharged to neutralize and separate the harmful substances in the sewage to ensure that the discharged sewage will not pollute the environment.
[0003] Specifically, in the process of sewage treatment, sedimentation treatment is first required. Through sedimentation, solid impurities in sewage are accumulated together to facilitate subsequent sewage filtration, avoid excessive solid impurities in the filtered sewage, and avoid clogging the filter. However, when sedimentation filtration is performed on domestic sewage, the sewage generated by life will be transported to the sewage treatment device through pipes from time to time. The irregular transportation of sewage to the sedimentation components of the treatment device will cause impact on the settled water or solid impurities, thereby affecting the filtration efficiency. For this reason, we propose a multi-stage sedimentation biological decomposition purification sewage treatment device. Utility Model Content
[0004] In view of the shortcomings of existing multi-stage sedimentation biological decomposition and purification sewage treatment devices, the utility model provides a multi-stage sedimentation biological decomposition and purification sewage treatment device, which has a buffer plate and an elastic rope installed inside the sedimentation tank. The buffer plate reduces the speed of sewage being transported to the sewage inside the sedimentation tank, and the elastic rope avoids the circulation speed of the sewage after sedimentation, thereby preventing the settled sewage from flowing back, thereby solving the problems raised in the above-mentioned background technology.
[0005] The utility model provides the following technical scheme: a multi-stage sedimentation biological decomposition and purification sewage treatment device, comprising a multi-stage treatment box, an upper cover is welded on the upper part of the multi-stage treatment box, the interior of the multi-stage treatment box is divided into five areas: a biological reaction box, a sedimentation box, a buffer box, a filter box and a drainage box, a solid impurity discharge pipe is installed on the outside of the sedimentation box, a collecting tank is fixedly connected to the interior of the sedimentation box, a buffer plate is installed on the upper end of the interior of the sedimentation box, a limiting sleeve is fixedly connected to the interior of the biological reaction box, a rotating rod is movably sleeved inside the limiting sleeve, a connecting plate and a first bevel gear are fixedly connected to the exterior of the rotating rod, a water storage funnel is fixedly connected to the exterior of the connecting plate, a second bevel gear is meshedly connected to one side of the first bevel gear, a rotating rod is installed at the lower end of the second bevel gear, a filter limiting sleeve is fixedly connected to the interior of the filter box, a spring and an extrusion positioning plate are movably sleeved inside the filter limiting sleeve, and an activated carbon filter layer is sandwiched between two groups of extrusion positioning plates.
[0006] Preferably, partitions are installed between the biological reaction tank, the sedimentation tank, the buffer tank, the filter tank and the drainage tank, and a drainage port is installed at the lower part of the other side of the multi-stage treatment tank.
[0007] Preferably, the upper end of the buffer plate has an inclination angle of 10°, an elastic rope is installed in the middle of the inner cavity of the sedimentation box, and the elastic rope is arranged at the lower end of the buffer plate.

[0011] Preferably, the lower portion of the rotating rod is movably sleeved inside the multi-stage processing box, and a stirring rod is installed outside the rotating rod.
[0012] Compared with the existing multi-stage sedimentation biological decomposition and purification sewage treatment device, the utility model has the following beneficial effects:
[0013] 1. The multi-stage sedimentation biological decomposition and purification sewage treatment device drives the sewage to be transported to the inside of the biological reaction box through the water inlet, and the sewage is accumulated in the water storage funnel. The water storage funnel drives the rotating rod to rotate, and through the linkage relationship, the rotating rod can be driven to rotate.

[0023] See also Figure 3 A partition is installed between the biological reaction tank 4, the sedimentation tank 5, the buffer tank 6, the filter tank 7 and the drainage tank 8. A drain port 10 is installed at the lower part of the other side of the multi-stage treatment tank 1. The interior of the multi-stage treatment tank 1 is divided into five different areas. When the liquid overflows the partition, the liquid can flow to another area. The biological reaction tank 4 stirs the sewage to facilitate the biological reaction of the sewage. At the same time, the sedimentation tank 5 settles the collected sewage. The buffer tank 6 buffers and collects the excess liquid after sedimentation. The filter box 7 performs multi-stage filtration on the sewage, and the filtered liquid is transported to the interior of the drainage tank 8 and discharged through the drain port 10.
[0024] See also Figure 3 The upper end of the buffer plate 12 has a 10° inclination angle, and an elastic rope 13 is installed in the middle of the inner cavity of the sedimentation tank 5. At the same time, the elastic rope 13 is arranged at the lower end of the buffer plate 12. The buffer plate 12 is arranged inside the sedimentation tank 5. After the sewage is initially stirred, it is transported to the inside of the sedimentation tank 5. At the same time, the buffer plate 12 blocks the passing sewage to prevent the sewage from being blocked too quickly when it is transported to the inside of the sedimentation tank 5, causing the sewage after sedimentation to react, thereby improving the sewage sedimentation efficiency. At the same time, an elastic rope 13 is installed at the lower part of the buffer plate 12. After the elastic rope 13 drives the solid impurities to settle, it prevents the sewage after settlement from flowing back to the upper end.

At the same time, the extrusion positioning plate 23 is pushed to move inward under the elastic action of the spring 22, that is, the stability of the activated carbon filter layer 24 when the position inside the filter limit sleeve 21 is limited is improved.
[0027] See also Figure 4 A water inlet 3 is installed on one side of the multi-stage treatment box 1, and the end of the water inlet 3 is located at the upper part of one side of the water storage funnel 17. A water storage tank is installed on the end of the water storage funnel 17. By extending one end of the water inlet 3 to the upper part of the water storage funnel 17, when the water inlet 3 drives the sewage to be transported to the inside of the multi-stage treatment box 1, countless sewage is transported to the inside of the water storage funnel 17, and at the same time, the water storage funnel 17 rotates downward after being pressurized, that is, the water storage funnel 17 can drive the rotating rod 15 to rotate, and when the sewage is continuously transported through the water inlet 3, the rotating rod 15 can circulate and rotate inside the multi-stage treatment box 1.
[0028] See also Figure 4The lower part of the rotating rod 20 is movably sleeved inside the multi-stage treatment box 1. At the same time, a stirring rod is installed on the outside of the rotating rod 20, which is meshed and connected with each other through the first bevel gear 18 and the second bevel gear 19. When the rotating rod 15 rotates, the rotating rod 15 can drive the rotating rod 20 to rotate synchronously. The rotation of the rotating rod 20 can drive the sewage to be stirred, thereby improving the biological reaction of the sewage and improving the subsequent sewage sedimentation efficiency.
[0029] Working principle: When in use, the sewage is transported to the interior of the multi-stage treatment box 1, and the sewage contacts the water storage funnel 17. After the water storage funnel 17 is filled with sewage, the sewage can drive the water storage funnel 17 to rotate, and at the same time drive the rotating rod 20 to rotate through the linkage relationship. The rotating rod 20 drives the sewage to stir, thereby increasing the biological reaction rate of the sewage. At the same time, after the sewage accumulates, the sewage is transported to the interior of the sedimentation tank 5 through the biological reaction tank 4, and the sedimentation tank 5 settles the sewage. When the sewage passes through the buffer plate 12, the buffer plate 12 reduces the sewage transportation speed to avoid the sewage entering the sedimentation tank 5 at a too high speed, resulting in the problem of sewage shaking after sedimentation. After the sewage settles, the upper layer of liquid is transported to the interior of the buffer tank 6, and the buffer tank 6 further settles the sewage. At the same time, the sewage is transported to the interior of the filter box 7, and the activated carbon filter layer 24 installed in the filter box 7 performs multi-stage filtration on the sewage passing through, and then the filtered and purified sewage is discharged through the drain outlet 10, and the accumulated solid impurities can be discharged by opening the solid impurity discharge pipe 9.
