Problems solved by technology

If the opening diameter is too large, the oxygen utilization rate is low; if the opening diameter is too small, the oxygen utilization rate is high, but the resistance increases
The rubber diaphragm is easy to age and tear, causing damage to the aerator, and requires a high pressure for aeration

Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] see Figure 1~Figure 5 As shown, the present invention provides an aeration device 1, including an aeration head 10, and an aeration connection piece 20 connected to an external aeration pipe (not shown). The external aeration pipe is used to provide oxygen to the aeration head 10, and then provide sufficient oxygen to the sewage to improve the sewage treatment effect. Oxygen in the present invention refers to oxygen-enriched gas, pure oxygen, compressed air and other gases that can meet the oxygen demand of aerobic organisms.

[0024] see figure 2 , Figure 4 with Figure 5 As shown, the aeration head 10 includes a main body 11 having an accommodating chamber (not labeled) for containing oxygen, a bottom bracket 12 for supporting the ...

Abstract

The invention provides an aeration device; the aeration device comprises an aeration head and an aeration connecting part, wherein the aeration connecting part is connected with an external aeration pipe; the aeration head comprises a main body part, a bottom bracket and a first joint part; the first joint part is combined with the aeration connecting part; an aeration micro-hole is arranged on the main body part; and the aeration connecting part comprises a second joint part combined with the first joint part and a connection part connected with the external aeration pipe. The aeration device disclosed by the invention is simple and steady in structure, steady to operate and high in aeration efficiency; oxygen conveyed by the external aeration pipe enters the main body part of the aeration head through the aeration connecting part and then enters sewage through the aeration micro-hole; by means of the opposite acting force generated when oxygen rushes out of the micro-hole, the aeration device vibrates slightly; therefore, the micro-hole is prevented from being blocked; and the service life of the aeration device is prolonged.

Description

technical field [0001] The invention relates to an aeration device, in particular to an aeration device with simple installation and maintenance and high oxygen utilization rate. Background technique [0002] The problem of water pollution is an environmental problem throughout the world. According to the methods used in sewage treatment, it can be divided into four types: physical method, chemical method, physical chemical method and biological method. Biological method is a method of using the metabolism of microorganisms in wastewater to decompose degradable organic matter in sewage. Because of its large processing capacity, low investment, and economical reliability, it has become the most common water treatment method in the world today. Among them, the aerobic biological method faces constraints such as aeration efficiency and the performance of the aeration device. [0003] Aeration types can be roughly divided into two categories: one is blast aeration, which uses a...
