Problems solved by technology

[0002] At present, in the wastewater treatment system, the traditional Y-shaped filter is mostly used in the wastewater inlet pipeline, and the wastewater is filtered by a single cross-section filter. Due to the high concentration of suspended solids in the wastewater, the filter is blocked quickly, and the filter has a flow capacity with the operation of the system. Gradually decrease until the filter is clogged; and the Y-type filter does not have an automatic flushing function during operation, therefore, during the operation of the wastewater treatment system, frequent blockage of the filter leads to intermittent shutdown of the wastewater treatment system

Embodiment 1

[0028] refer to figure 1 and figure 2 , is the first embodiment of the present invention, which provides a filter device for a waste water pipe mouth, including a filter unit 100 and a pressurization unit 200 .

[0029] The filter unit 100 includes a first pipeline 101, a second pipeline 102 and a filter cover 103, the second pipeline 102 is arranged on one side of the first pipeline 101, and the filter cover 103 is detachably connected to the first One end of the pipeline 101, the detachable connection here adopts the existing connection method, such as screw connection and the like.

[0030] The pressurization unit 200 is arranged inside the filter unit 100, and includes a fixed assembly 201, a rotary assembly 202 and a flow distribution assembly 203. The fixed assembly 201 is connected between the first pipeline 101 and the filter housing 103. The rotary assembly 202 is rotatably connected inside the fixed assembly 201 , and the flow distribution assembly 203 is arranged...

Embodiment 2

[0033] refer to image 3 and Figure 4 , is the second embodiment of the present invention, and this embodiment is based on the first embodiment.

[0034] Specifically, the fixing assembly 201 includes a fixing plate 201a, a fixing cover 201b and a fixing ring 201c, the fixing cover 201b is fixed on the inner wall of the first pipe 101 through the fixing plate 201a, and the fixing ring 201c is fixed on The fixed cover 201b is away from one end of the fixed plate 201a; there are multiple fixed plates 201a, which are evenly distributed on the circumference of the fixed cover 201b, and are fixedly connected to the inner wall of the first pipeline 101 at the same time. The connection adopts the existing connection method, such as welding and so on.

[0035] Further, the rotating assembly 202 includes a first rotating ring 202a, a first rotating shaft 202b and a first rotating plate 202c, the first rotating ring 202a is fixedly connected in the middle of the fixed cover 201b, and...

Embodiment 3

[0040] refer to Figure 1 to Figure 5 , is the third embodiment of the present invention, which is based on the first two embodiments.

[0041]Specifically, the diverter assembly 203 includes a diverter plate 203a, the diverter plate 203a is fixed on the end of the fixed ring 201c away from the fixed cover 201b, and is set in a tapered shape to facilitate the flow of water and reduce resistance.

[0042] Preferably, the filter unit 100 further includes a connecting pipe 104, the connecting pipe 104 is connected between the second pipe 102 and the fixed cover 201b, and the connection between the connecting pipe 104 and the fixed cover 201b A one-way valve 105 is set at the place, so that water can only flow from the second pipeline 102 to the first pipeline 101.

[0043] Preferably, the fixing cover 201b is provided with a plurality of second through holes 201b-1, so that the water flowing into the fixing assembly 201 can flow out through the second through holes 201b-1.

Abstract

The invention discloses a filtering device for a waste water pipeline opening, the filtering device comprises a filtering unit and a pressurizing unit, the filtering unit comprises a first pipeline, a second pipeline and a filtering cover, the second pipeline is arranged on one side of the first pipeline, and the filtering cover is detachably connected to one end of the first pipeline; the pressurizing unit is arranged in the filtering unit and comprises a fixing assembly, a rotating assembly and a flow dividing assembly, the fixing assembly is connected between the first pipeline and the filtering cover, the rotating assembly is rotationally connected in the fixing assembly, and the flow dividing assembly is arranged at the end, close to the filtering cover, of the fixing assembly. According to the device, the pressurizing unit is additionally arranged, when water enters through the filtering cover and the first pipeline, the rotation assembly and the flow dividing assembly can increase water flow and improve the flow speed, and during flushing, high-pressure water flow drives the rotation assembly to rotate, and 360-degree back flushing can be conducted on the filtering cover.
