Description
MUNICIPAL SEWAGE TREATMENT DEVICE LU504873
The present invention relates to the technical field of municipal sewage treatment, in particular to a municipal sewage treatment device.
Municipal sewage treatment refers to the measures taken to change the nature of sewage so that it does not harm the environmental waters. Municipal sewage treatment is generally divided into three levels: primary treatment using a physical treatment method to remove insoluble pollutants and parasitic eggs from sewage, secondary treatment using a biological treatment method to oxidize and degrade all kinds of complex organic substances from sewage into simple substances; and tertiary treatment using chemical precipitation, biochemistry and physical chemistry methods to remove phosphorus, nitrogen, refractory organic substances and inorganic salts from sewage. A selection of specific level as a reasonable treatment should depend on the treatment requirements of the final effluent.
Generally, municipal sewage is usually collected by sewage pipelines and discharged into sewage treatment plants and treated in the treatment tank. Drainage ends of the sewage pipelines are usually buried in inner walls of the treatment tank, so that sewage can be directly discharged into the sewage treatment tank. However, this way of direct discharge may cause that impurities and garbage from the ground are discharged into the sewage treatment tank, and when the drainage pipes of sewage pipelines have little displacement or stop discharging, the impurities in the sewage may stay at pipeline ports so that impurity adhesion may be caused and impurity blocks are larger over time, and eventually a flow of sewage discharge is affected. Therefore, a municipal sewage treatment device is proposed.
In view of the above problems, the present invention provides a municipal sewage treatment device so as to improve the above problems.
In order to achieve the above objective, the present invention adopts the following technical solutions: a municipal sewage treatment device, including an external box, specifically, two sides of the external box are fixedly connected to limiting frames, interiors of the limiting frames are slidably sleeved with a supporting plate, a top of the supporting plate is clamped to a sewage pipeline, an interior of the external box is rotatably sleeved with rotary wheels, an exterior of one side of each of the rotary wheels is fixedly connected to a guide plate, an interior of the external box is slidably sleeved with a built-in frame, an inner side of the built-in frame is rotatably sleeved with silk thread filter rods, exteriors of the silk thread filter rods are fixedly connected to winding rods, and a bottom of the built-in frame on an inner wall of the external box is fixedh}504873 connected to a filter plate.
Preferably, two sides of the external box are fixedly connected to limiting columns, exteriors of the limiting columns are arc-shaped, interiors of the limiting columns are slidably sleeved with positioning rods, one end of each of the positioning rods is provided with a flat plate, interiors of the flat plates are provided with threaded holes, and exteriors of the positioning rods are sleeved with nuts.
Preferably, an inner wall above the external box is fixedly connected to a built-in groove, an interior of the built-in groove is rotatably sleeved with a screw, an exterior of the screw is threadedly sleeved with a downward pressing plate, and a bottom of an outer side of the downward pressing plate is arc-shaped and is clamped to a top of the sewage pipeline.
Preferably, an outer side of each of the rotary wheels is cone-shaped, each of the guide plates is curve-shaped in an exterior of each of the rotary wheels, and one side of each of the rotary wheels, located in an interior of the external box, is fixedly connected to a retaining collar.
Preferably, a top of the screw is welded with a hexagonal prism, an exterior of the hexagonal prism is sleeved with a hexagonal socket nut; outer sides of two ends of the supporting plate are fixedly connected to clamping plates, the clamping plates are slidably sleeved inside the corresponding limiting frames, exteriors of the clamping plates are equipped with bolt and nut pairs, and the bolt and nut pairs are rotatably sleeved inside the corresponding limiting frames.
Preferably, an outer side of the external box is fixedly connected to positioning bolts, an outer side of the built-in frame is fixedly connected to an outer baffle, the outer baffle is slidably sleeved on outer sides of the positioning bolts, and exteriors of the positioning bolts are equipped with nuts.
Preferably, there are three groups of the silk thread filter rods and the rotary wheels, the winding rods outside the silk thread filter rods on the left and right sides are symmetrically arranged, and the winding rods outside the silk thread filter rods in a middle are offset from those outside the silk thread filter rods on the left and right sides.
Preferably, a bottom of the external box is hollow, and an inner side of the built-in frame is not in direct contact with the retaining collar.
The municipal sewage treatment device provided by the present invention has the following beneficial effects. 1. According to the municipal sewage treatment device, when the port of the sewage pipeline extends out of inner walls of the treatment tank, the supporting plate is sleeved inside the limiting frames, a height of the supporting plate is fixed by the bolt and nut pairs on an outer 204873 side of the clamping plates fixedly connected to the supporting plate, then the hexagonal socket nut is taken out of the hexagonal prism, the downward pressing plate is sleeved outside the screw, the hexagonal socket nut is sleeved outside the hexagonal prism, and the hexagonal socket nut is rotated to drive the screw to rotate inside the built-in groove and then press the downward pressing plate down on a top of the sewage pipeline, so that the downward pressing plate and the supporting plate clamp the external box outside the sewage pipeline, thus completing connections; when the port of the sewage pipeline is flush with the inner walls of the treatment tank, positioning rods are fixed on two sides of the sewage pipeline through bolts, then the limiting columns are sleeved outside the positioning rods and the nuts outside the positioning rods are rotated to complete the connections of the external box, so that the device can be connected and installed according to conditions of different sewage pipelines, and at the same time, the external box and the rotary wheels and the silk thread filter rods sleeved inside are easily disassembled in the later stage, thus improving a convenience of subsequent cleaning of the device.

3. According to the municipal sewage treatment device, an exterior of the built-in frame is fixedly connected to an outer baffle.
When the device needs to clean the rope-like impurities wound outside the silk thread filter rods and the winding rods, the external box can be taken out of the sewage pipeline, the nuts outside the positioning bolts are rotated to release the outer baffle, and then the outer baffle and the built-in frame are pulled out of the external box, so that 204873 the silk thread filter rods and the winding rods can be cleaned, and gaps of the guide plates and filter holes of the filter plate can be flushed by a cleaner because the filter plate and the rotary wheels are exposed to the sight of the cleaner, thus ensuring the flow of subsequent sewage discharge.
