Description

Preliminary treatment device for sewage recovery

Technical Field

The utility model belongs to the technical field of sewage treatment technique's technique and specifically relates to a preliminary treatment device of sewage recovery is related to.

Background

At present, along with the development of cities, the pollution of water resources is gradually serious, and the water pollution means that the use value of water produced by harmful chemical substances is reduced or lost, so that the water resources are seriously wasted. Therefore, it is a necessary work to recycle the sewage, and before the water purification work of the sewage, it is required to primarily treat the sewage for filtering large-volume impurities in the sewage.

Current sewage preliminary treatment all utilizes filter equipment, lets in sewage among the filter equipment, utilizes the filter screen in the filter to filter sewage to reach the purpose of preliminary detach impurity.

The above prior art solutions have the following drawbacks: after filtering for a long time, impurities are easily accumulated on the filter screen, so that the filter screen is blocked, and the filtering efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

To the deficiency that prior art exists, one of the purposes of the utility model is to provide a sewage recovery's preliminary treatment device, have the effect that can prevent the filter screen jam.

The above object of the present invention can be achieved by the following technical solutions:

the utility model provides a sewage recovery's preliminary treatment device, the novel nipple rectifier comprises a cylindrical shel, be equipped with first baffle and second baffle respectively along the direction of height in the barrel, first baffle is in second baffle top, the mouth of a river that leaks has all been seted up on first baffle and second baffle, the mouth of a river that leaks of first baffle middle berth is equipped with first filter screen, first filter screen becomes the bellied sphere form that makes progress, be equipped with the second filter screen in the mouth of a river that leaks of second baffle, the second filter screen becomes the cone setting towards first filter screen direction, the aperture of second filter screen is less than first filter screen, be equipped with the water inlet at the top of barrel, the bottom of barrel becomes to leak hopper-shaped setting, and the most advanced of leaking hopper-shaped is equipped with.

Through adopting above-mentioned technical scheme, send into the barrel with sewage inside from the water inlet, sewage from the top flows through first filter screen and second filter screen in proper order, in the great first filter screen department in aperture, filters out great impurity, filters out tiny particle impurity in the less second filter screen department in aperture, discharges from the delivery port at last.

When through first filter screen, because first filter screen becomes the bellied sphere that makes progress, consequently when bold impurity is blockked on first filter screen, the surface of impurity is difficult to laminate completely with the first filter screen surface that becomes the cambered surface, thereby reduce the area of stress of impurity on first filter screen, reduce the ability of snatching of impurity to the wire side under hydraulic effect, make it can slide along the cambered surface under the drive of rivers, make impurity be difficult for adsorbing in first filter screen surface and cause the jam, and the sphere has bigger filter area, under the condition that the same mouth of a river leaks, can have better filtration efficiency.

When passing through the second filter screen, because great impurity has been strained in first filter screen department and has been strained, so strain impurity on the second filter screen be the tiny particle impurity, tiny particle impurity is more smooth than large granule impurity surface, and it is difficult for the card to locate on the mesh.
