Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples. The following experimental examples and examples are intended to further illustrate but not limit the invention.

Example one

Referring to fig. 1 to 3, the present invention provides a dual-channel non-leakage tubular microporous aerator 100, wherein the dual-channel non-leakage tubular microporous aerator 100 includes a connection joint 10, a lining tube 20, an air distribution tube 30 and a clamp 40, which are coaxially fixed to the connection joint 10.

The connector 10 includes an inner tubular body (not shown) and an outer tubular body 12. The liner tube 20 is communicated and fixedly connected with the inner-layer tube body, and the gas distribution tube 30 is communicated and fixedly connected with the outer-layer tube body 12.

Specifically, the inner pipe is connected to an external water supply device, and the outer pipe 12 is connected to a blower. That is, the inner tube is used to supply water into the lining tube 20, and air generated by the blower is introduced into the gap between the lining tube 20 and the air distribution tube 30 through the gap between the inner tube and the outer tube 12. In this way, water is poured into the liner tube 20 through the inner tube, so that the weight of the dual-channel no-leakage tubular microporous aerator 100 is increased, and when air is supplied inwards by the blower, the dual-channel no-leakage tubular microporous aerator 100 can be effectively prevented from floating upwards.

The hoop 40 is disposed at the joint of the air distribution pipe 30 and the outer pipe 12, so as to further enhance the connection tightness between the air distribution pipe 30 and the outer pipe 12.

Preferably, the material of the clip 40 is stainless steel.

The liner 20 includes a tube wall 21 and two grooves 22 formed from the tube wall 21 to a core tube. The groove 22 extends along the axial direction of the liner tube 20, and the groove 22 and the gas distribution pipe 30 sleeved outside the liner tube 20 together form a gas distribution flow passage 101.

Preferably, the ratio of the extension of the first circular wall 33 to the extension of the second circular wall 34 is 2: 1. during the aeration process, since the extension length of the first circular wall 33 is greater than that of the second circular wall 34, the side of the micro-aeration holes 102 close to the outer surface 32 is thinner and the side close to the inner surface 31 is thicker, which facilitates the opening of the micro-aeration holes 102 and increases the difficulty of the micro-impurities in the sewage entering along with the closing of the micro-aeration holes 102.

Preferably, the material of the liner tube 20 is ABS plastic, so that the liner tube 20 has strong pressure resistance, aging resistance, corrosion resistance, acid and alkali resistance, and UV resistance; the air distribution pipe 30 is made of EPDM synthetic rubber, so that the air distribution pipe 30 has better rebound resilience and tightness.

By arranging the micro aeration holes 102 formed by the first circular wall 33, the second circular wall 34 and the annular inner wall 35, the accommodating space surrounded by the annular inner wall 35 has certain impurity accommodating capacity, so that micro impurities in sewage cannot directly enter the air distribution pipe 30 but temporarily store in the accommodating space, and are discharged along with the next opening of the machine, and the micro aeration holes 102 are prevented from being blocked in the sewage with complicated conditions.
