Rotary water distributor of microbial filter bed

Abstract

A rotary water distributor of a microbial filter bed comprises a water inlet pipe and a rotary sleeve; the upper end of the water inlet pipe is closed, and at least one rotational flow water outlet hole is formed in the pipe wall of the upper portion of the water inlet pipe around the central axis in an annular array mode; an annular storage tank is arranged on the lower portion of the water inlet pipe, mercury is contained in the annular storage tank, and the lower end of the rotating sleeve is inserted into the annular storage tank and located below the liquid level of the mercury; the upper end of the rotating sleeve is closed, and at least three cavity separating plates are fixedly arranged on the inner sleeve wall of the rotating sleeve around the central axis in an annular array; and at least two water distribution pipes are connected and arranged on the outer sleeve wall of the rotating sleeve around the central axis in an annular array. Tangential water columns are sprayed outwards through the rotational flow water outlet holes in the water inlet pipe, the water columns impact on the cavity partition plate, so the rotary sleeve can be pushed to rotate, the water distribution pipe is driven to rotate, and a circular water distribution range is formed.

Description

technical field [0001] The invention belongs to the technical field of microbial filter beds, and relates to a device for distributing water to microbial filter beds by rotating through hydraulic drive, in particular to a rotary water distributor for microbial filter beds. Background technique [0002] Microbial filter beds are widely used in sewage treatment, and the water distributor is an important part of it. Whether the water distribution is uniform or not directly determines the effect of sewage treatment. In the existing microbial filter bed, the filter bed with a circular design is one of the main structural forms. In order to make the water distribution on the filter bed more uniform, people have designed a rotary water distributor, which can distribute water by rotating. Therefore, the sprinkled water can be evenly distributed on the circular filter bed, and the rotary water distributor is widely used for water distribution on the circular microbial filter bed. ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a rotary water distributor for a microbial filter bed. The main technical problem to be solved is that the existing rotary water distributor requires power consumption, and metal structural devices such as motors and bearings It is easy to rust in the humid environment in contact with sewage for a long time, which makes the operation and maintenance of the rotary water distributor inconvenient and high in cost
