Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an impurity removal device for wastewater treatment. Background Art

[0002] Wastewater treatment refers to the treatment of wastewater from different sources such as domestic sewage, industrial wastewater, agricultural wastewater, etc., in order to reduce the content of harmful substances, comply with environmental regulations, and protect water resources and the environment. The main methods of wastewater treatment include physical treatment, chemical treatment, and biological treatment. When performing physical treatment, the wastewater is passed through a bag filter, which is equipped with a filter element to remove impurities from the wastewater.

[0003] Wastewater contains a large amount of impurities. When the wastewater is directly passed into the bag filter, both larger and smaller impurities are filtered out by the filter element. However, after larger impurities enter the filter element, they may damage the filter element, resulting in reduced impurity removal effect. Therefore, the present application provides an impurity removal device for wastewater treatment to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an impurity removal device for wastewater treatment to solve the problem that when larger impurities enter the filter element, the filter element may be damaged, resulting in reduced impurity removal effect.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A wastewater treatment impurity removal device comprises a cylinder, a water outlet is arranged at the bottom of the cylinder, a water inlet is arranged on the surface of the cylinder, a cover is rotatably connected to the top of the cylinder, the water inlet is connected to the flow channel of the cover, a filter element is arranged in the cylinder, and further comprises:

[0007] The pre-filtering mechanism comprises a fixed ring fixed on the inner wall of the cylinder, a circular ring is supported on the top of the fixed ring, a plurality of trapezoidal plates are fixed on the top of the circular ring, the plurality of trapezoidal plates are arranged in a circular array in the center of the circular ring, and a diversion cylinder is connected to the top of the plurality of trapezoidal plates.

[0008] Preferably, a retaining ring is fixed to the circumferential surface of the annular ring, and during use, the retaining ring is located inside the cylinder.

[0009] Preferably, the bottom of the retaining ring is provided with a chamfer.

[0010] Preferably, a connecting rod is fixed between the circular ring and the diverter cylinder.

[0011] Preferably, a circular hole connected to the inside of the diverter tube is opened on the top of the diverter tube, a filter plate is fixed on the inner wall of the circular hole, an inclined hole connected to the inside of the diverter tube is opened on the circumferential surface of the diverter tube, and the aperture of the filter plate is smaller than the spacing between adjacent trapezoidal plates.

[0012] Preferably, the circumferential surface of the diverter cylinder is provided with a plurality of square holes which are connected with the interior of the diverter cylinder.

[0013] Preferably, a diverter block is fixed to the bottom of the inner wall of the diverter cylinder.

[0014] Preferably, a positioning hole is provided at the bottom of the circular ring, and a positioning block is fixed at the top of the fixing ring. When in use, the positioning block is snapped into the positioning hole.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, by setting up a pre-filtration mechanism, when the wastewater enters the trapezoidal plate, the larger impurities in the wastewater will be filtered out to prevent the impurities from damaging the filter element. The filtered impurities will move downward along the trapezoidal plate to prevent the impurities from randomly accumulating on the top of the trapezoidal plate, thereby ensuring the filtration efficiency and making it more convenient to handle the impurities in the later stage.

[0017] By setting inclined holes, square holes and diversion blocks, sewage enters the diversion cylinder from the filter plate or square hole and is sprayed out from the inclined holes. The inclined holes are located between adjacent trapezoidal plates, and the inclination direction of the inclined holes is the same as that of the trapezoidal plates. The water flow sprayed through the inclined holes can push the impurities remaining on the trapezoidal plates downward to avoid clogging the gaps between the trapezoidal plates.

[0033] The pre-filtering mechanism 6 comprises a fixed ring 61 fixed to the inner wall of the cylinder 1, a circular ring 62 is supported on the top of the fixed ring 61, a plurality of trapezoidal plates 63 are fixed on the top of the circular ring 62, the plurality of trapezoidal plates 63 are arranged in a circular array with the circular ring 62 as the center, and a diversion cylinder 64 is connected to the top of the plurality of trapezoidal plates 63.

[0034] like Figure 4 As shown, in this embodiment, a retaining ring 7 is fixed on the circumferential surface of the circular ring 62. When in use, the retaining ring 7 is located in the cylinder 1, and impurities are blocked by the retaining ring 7, which makes it more convenient to clean the impurities later.

[0035] like Figure 4 As shown, in this embodiment, a chamfer is provided at the bottom of the retaining ring 7, and the chamfer can guide the retaining ring 7 so that the retaining ring 7 is easier to be placed in the cylinder 1.

[0036] like Figure 4 As shown, in this embodiment, a connecting rod 12 is fixed between the circular ring 62 and the diverter tube 64, and the connecting rod 12 improves the stability of the connection between the circular ring 62 and the diverter tube 64.
