Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and more specifically, to an integrated sewage treatment device for rural domestic sewage. Background Art

[0002] Rural domestic sewage mainly comes from the washing, bathing and kitchen wastewater of villagers and some factory staff dormitories around the village, as well as septic tank wastewater. The pollutants in sewage are simple and easy to handle. They mainly contain organic matter, nitrogen and phosphorus nutrients, suspended solids and bacteria, and the water volume varies greatly. At present, most rural domestic sewage adopts the method of natural discharge nearby, and is purified by the self-purification capacity of the receiving water body (rivers, streams, ponds, depressions, drainage and irrigation canals). The existing rural domestic sewage treatment equipment is usually not compact enough, occupies a large area, and the energy consumption of the equipment is also large, which is not suitable for the growing trend of energy conservation and environmental protection; in addition, the purification effect of the existing rural domestic sewage treatment equipment is poor and needs to be improved.

[0003] The document with prior art publication number CN 208394914 U provides an integrated rural domestic sewage treatment device, which reduces overall energy consumption by optimizing the start and stop of a water pump and an aeration fan. The new compact integrated device has low energy consumption, small footprint, and excellent treatment effect. By providing a filtering device, the sewage is filtered through two stages of a primary filter screen and a secondary filter screen, thereby improving the filtering effect. By optimizing the structure of a stirring paddle in a sewage treatment tank, the structure is novel in design and has high stirring efficiency, thereby improving the sewage treatment effect.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: after the sewage is poured into the sewage pool and the larger debris is filtered through the filtering device, some small particles such as silt will settle in the sewage pool, making it inconvenient to clean it in time.

[0005] In view of this, we propose an integrated sewage treatment device for rural domestic sewage. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] The purpose of this application is to provide an integrated sewage treatment device for rural domestic sewage, which solves the technical problems in the above-mentioned background technology and achieves the technical effect of cleaning the sludge in the sedimentation tank without releasing the sewage in the sedimentation tank.

[0008] 2. Technical solution

[0009] The technical solution of the present application provides an integrated sewage treatment device for rural domestic sewage, including a sewage pool with a filtering device, a sedimentation tank installed through the bottom of the sewage pool, a collection bin for collecting silt after sedimentation installed inside the sedimentation tank, an opening and closing mechanism for separating the silt and the sedimentation tank is rotatably arranged in the collection bin, and a dredging mechanism for cleaning the silt in the collection bin is slidably arranged in the collection bin.

[0010] By adopting the above technical solution, sewage is poured into the sewage pool, and debris is filtered out through the filtering device. The filtered sewage enters the sedimentation tank, and the sludge after sedimentation is collected in the collection bin. When cleaning, the collection bin and the sedimentation tank are closed and separated by the opening and closing mechanism, and finally the sludge accumulated in the collection bin is scraped out by the dredging mechanism.

[0011] As an optional solution of the technical solution of the present application document, the collecting bin includes two V-shaped guide plates and a collecting pipe fixed between the two guide plates, the collecting pipe is placed on one side of the guide plate as an open structure, and a sewage outlet is provided on one side of the sedimentation tank close to the collecting pipe, and the sewage outlet is detachably connected with a sealing plate.

[0012] By adopting the above technical solution, two V-shaped guide plates are used to guide the sludge into the collecting pipe, and the sludge is collected through the collecting pipe. The sewage outlet corresponds to the collecting pipe, so that the sludge in the collecting pipe can be discharged through the sewage outlet. The sealing plate and the sewage outlet are detachably connected by multiple buckles.

[0013] As an optional solution to the technical solution of the present application document, the opening and closing mechanism includes an arc tube adapted to the inner diameter of the collection pipe, an axis rod rotatably connected in the sedimentation tank, a fixing plate fixed between the axis rod and the arc tube, and a handle fixed vertically to the axis rod.

[0014] By adopting the above technical solution, the arc tube rotates to the upper opening of the collecting tube and can completely close the opening, so that the upper opening of the collecting tube can be opened and closed by rotating the arc tube, and the shaft can be rotated by the handle.

[0015] As an optional solution of the technical solution of the present application document, the handle is provided with a locking screw which can be threadedly connected to the sedimentation tank.

[0016] By adopting the above technical solution, when the handle is in a horizontal state, the arc tube closes the opening of the collection tube, and the locking screw can be threadedly connected to the sedimentation tank to improve the stability of the arc tube when closing the collection tube.

[0017] As an optional solution to the technical solution of this application document, the dredging mechanism includes a scraper adapted to the inner diameter of the collection pipe and a pull rod fixed on the scraper and parallel to the shaft rod, and the scraper is provided with a movable opening adapted to the shaft rod and the fixed plate.

[0018] By adopting the above technical solution, the scraper is an incomplete disc, and a gap is reserved with the open end of the arc tube to avoid interference. The pull rod is placed in the sedimentation tank. After the sealing plate is removed, when the arc tube closes the opening of the collection tube, the outer edge of the scraper fits with the inner wall of the collection tube. The pull rod is pulled outward from the sewage outlet, and the sludge in the collection tube can be cleaned by the scraper. After the cleaning is completed, the scraper is pushed into the collection tube, and the sealing plate closes the sewage outlet. The handle can be rotated 180 degrees, and finally the scraper slides along the shaft and the fixed plate through the movable port to improve the sliding stability of the scraper.
