Diaphragm aerator with good sealing property

Abstract

The invention relates to a diaphragm aerator with good sealing property. The diaphragm aerator with the good sealing property comprises a cover body, wherein a diaphragm is arranged at the upper end of the cover body; a flow guide partition plate is arranged on the side of the cover body; a sawtooth-shaped air distribution head is arranged at the joint between the lower end of the cove body and the flow guide partition plate; an inner nut is arranged at the center of the sawtooth-shaped air distribution head; an air inlet pipe matched with the inner nut is arranged on the inner nut. The diaphragm aerator with the good sealing property is simple in structure, convenient to use, large in aeration service area and great in possibility of slipping sludge; an aeration diaphragm has remanufacturing scalability; due to the adoption of mechanized assembly, the diaphragm aerator is good in peripheral sealing performance, high in strength, good in stability performance and convenient to maintain and replace; the service life is prolonged; the working efficiency is improved.

Description

technical field [0001] The invention relates to a diaphragm aerator with good sealing performance. Background technique [0002] Diaphragm microporous aerator is the latest aeration device developed in the 1980s. The device has small aeration bubbles, large gas-liquid area, uniform bubble diffusion, no hole clogging, and strong corrosion resistance. There are some problems that are difficult to solve in operation, such as: the diaphragm falls off, the diaphragm is torn, the diaphragm cannot be opened, and the sludge enters the bronchus. The chip is easily damaged, and it is inconvenient to replace and maintain, which reduces the work efficiency of the staff. The sealing performance of the product is poor, and it needs to be replaced frequently, which increases the production cost. The strength is poor, the stability is not good, and there are potential safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to over...
