Problems solved by technology

When in use, the air first enters the chassis, and then passes through the supporting plate and is discharged from the micropores on the rubber cloth air plate to diffuse into the sewage to form bubbles and escape the water surface, so as to achieve the purpose of flushing oxygen into the sewage; but when the system stops using , there is no pressure in the system, sludge and sundries often deposit on the rubber cloth air plate, block the micropores on it, and even enter the ventilation pipe system, affecting the next use, and during use, it is easy to be damaged by the pipe The foreign matter inside blocks the air outlet, thus affecting the normal operation of the entire system

Abstract

The invention discloses a filter type disc type microporous aerator provided with a rubber diaphragm. The filter disc type microporous aerator comprises a main body, a check valve, a diaphragm, an expansion ring, a gland and a wedge, wherein the check valve is arranged in an air inlet; a steel ball is arranged in the check valve, and the diaphragm and the expansion ring are arranged at the upper end of the check valve sequentially; the diaphragm and the expansion ring are fixedly connected through the gland, micropores are formed in the diaphragm, the wedge and the main body are connected on an aeration conduit in a matched manner, a filter is arranged at the lower end of the check valve, and a seal ring is arranged at the upper end of the check valve in a sleeving manner. By mounting the check valve, sewage can be effectively prevented from entering a ventilating duct system, and the service life of the product is prolonged; by arranging the filter at the lower end of the check valve, an air outlet can be effectively prevented from being blocked by foreign matter in the pipeline, an inlet of the filter is prevented from being blocked by the foreign matter by aid of the conical shape design of the filter, and accordingly, stable operation of the system is guaranteed.

Description

technical field [0001] The invention relates to an aeration device for sewage treatment, in particular to a filter type disc rubber membrane microporous aerator. Background technique [0002] Among the methods of sewage treatment, biochemical treatment is an effective method, which is economical and simple. In order to improve its treatment effect, there must be sufficient dissolved oxygen in the sewage to be treated to promote the oxidation reaction in the sewage. The aerator is the main device for supplying oxygen to the sewage. The existing aerator head produces relatively large air bubbles in practical application, so the contact area between the air bubbles and water is small, and the speed of oxygen dissolving in water is relatively slow. A general microporous aerator is composed of components such as a chassis, a pallet, a gland, and a rubber air distribution plate, and the chassis is connected to a ventilation duct. When in use, the air first enters the chassis, a...
