Embodiment 1

[0051] In the pretreatment stage of sewage treatment, the commonly used pretreatment equipment in the prior art is a grille device, such as an inflow orifice grille device. The existing grille device includes a ring formed by connecting several mesh plates 102 end to end Shaped screen mechanism 101, driving mechanism and frame 107 for supporting endless mesh mechanism 101 and driving mechanism, as an example, as figure 1 As shown, the driving mechanism includes a driving motor 104, a main shaft 105, and a sprocket 106 arranged on the main shaft 105. The main shaft 105 is installed on the upper part of the frame 107 and is connected with the driving motor 104. The upper end of the annular screen mechanism 101 Winding on the sprocket 106, the lower end extends into the sewage to be treated, the driving motor 104 drives the main shaft 105 to rotate, thereby bringing the ring-shaped screen mechanism 101 to rotate, so that the screen 102 in the ring-shaped screen mechanism 101 is co...

Embodiment 2

[0058] This embodiment provides a flushing system with another structure, the flushing device includes a first flushing part and a second flushing part, and the first flushing part and the second flushing part are respectively connected to the outlet of the flushing pump 201 By the way, the first nozzle 204 and the second nozzle 206 are respectively arranged in the first flushing part and the second flushing part. In this solution, the inner flushing and the outer flushing are separately connected to the outlet of the flushing pump 201 (i.e. parallel), so that the inner flushing and the outer flushing can be realized at the same time, and the inner flushing and the outer flushing can be performed separately, which is more convenient to use. The scope of application is wider.

[0059] Preferably, the first flushing part includes at least one first flushing pipe 203, the first nozzles 204 are respectively arranged on the first flushing pipes 203, and the second flushing part inclu...

Embodiment 3

[0072] In order to achieve good flushing, especially inner flushing, to avoid clogging of the pores, it is usually necessary to adjust the flushing direction of the inner flushing, that is, to adjust the spray direction of the nozzle on the first flushing pipe 203, so that the staff can Factors, reasonably adjust the injection direction of the nozzle on the first flushing pipe 203, in order to achieve such a purpose, this embodiment 3 provides a flushing system with another structure, and the main difference with embodiment 1 or embodiment 2 is that this In the flushing system provided in the embodiment, the first flushing pipe 203 is movably connected to the connecting pipe, so that the first flushing pipe 203 can rotate relative to its own central axis, such as Figure 9-Figure 13 As shown, it is convenient for the staff to adjust the orientation of the first nozzle 204 on the first flushing pipe 203, so as to achieve the purpose of adjusting the spraying direction of the fir...

Abstract

The invention relates to a flushing system, a sewage treatment system and a method for flushing a screen plate. The flushing system comprises a flushing pump and a flushing device body used for flushing the screen plate; a suction inlet of the flushing pump is used for being communicated with flushing water, a discharge outlet of the flushing pump is communicated with the flushing device body, andthe flushing device body is provided with a plurality of first nozzles used for flushing the inner side face of the screen plate and a plurality of second nozzles used for flushing the outer side face of the screen plate. The flushing system is compact in structure, the mode of combining inner side flushing and outer side flushing is adopted, the defect that only outer side back flushing is usedcan be overcome, and thus the cleaning effect of the screen plate is effectively improved; in a scene that water contains a viscous agent, the problem of blockage of filtering holes in the screen plate can be effectively solved, particularly the problems that in the prior art, the filtering holes of a conical structure are prone to blockage when only outer side flushing is adopted, and duct blockage is further compacted through outer side flushing water pressure can be effectively solved, and the flushing system is particularly suitable for occasions where the conical filtering holes are formed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a flushing system and a sewage treatment system. Background technique [0002] The internal inflow orifice grid is a pretreatment equipment for the sewage treatment plant to accurately and efficiently remove hair and fine fibers in the sewage. Its stable operation requires backwash water to clean the screen in time, and remove the grid attached to the inside Clean the slag and keep the channels unobstructed to ensure the water passing capacity of the grille; in the prior art, the internal flow type orifice grille can be divided into metal and non-metal according to the material of the filter screen. Among them, the metal mesh The thickness of the plate is relatively thin, the channel of the filter hole on it is short, and the equal-diameter through hole is mostly used, and the non-metal mesh plate is relatively thick, and the channel of the filter hole on it is...
