Problems solved by technology

But it still has some defects, the known microporous aeration tube no matter how its micropore geometric shape, the channel of its perforation and the basal plane of material are vertical direction, has just influenced the closing of the micropore of gas distributor like this The gas distributor is generally immersed in the liquid for a long time, and it is used for a long time, there is still the possibility that the liquid penetrates into the gas distributor through the micropores

Embodiment Construction

[0016] As shown in Figure 1, the oblique microporous aeration hose still includes a hose body 1 made of elastic flexible material, which can be flexible plastic or rubber, and the hose body 1 has high density in the axial and radial directions. The aeration microholes 2 penetrating the pipe wall are evenly arranged, as shown in Figure 2, the aeration microholes 2 are in a non-perpendicular inclined state to the surface of the pipe wall, the larger the inclination angle, the better the closing effect, but the more difficult it is to manufacture Generally, it is advisable to form an included angle of 5 to 30 degrees with the axial section passing through the centerline, and the directions of all aeration microholes 2 are consistent with the included angle with the axial section passing through the centerline. As shown in Figure 1, in order to further improve the effect, the aeration micropore 2 is preferably formed of a slightly oblique incision, and the incision is parallel to t...

Abstract

The invention relates to a main element - an inclined microporous aeration soft tube of a gas distributor, comprising a soft tube main body (1) made of elastic soft material and aeration micropores (2) that run through the tube wall and are evenly arranged on the soft tube main body (1) with high density. The invention is characterized in that: the aeration micropores (2) form a non-vertical but inclined status with the surface of the tube wall. Compared with the prior art, as the aeration micropores (2) of the invention form a non-vertical but inclined status with the surface of the tube wall, water around the soft tube presses and squashes the aeration micropores (2) at one side to close the micropores, thus, compared with the existing mircroporous aeration soft tubes that are deformed, then the tube diameter shrinks and becomes smaller and the micropores close with external water pressure, the effects of the inclined microporous aeration soft tube can be more easily achieved, therefore, the invention has better closing capacity and performance for avoiding blockage.

Description

technical field [0001] The invention relates to an oblique microporous aeration hose, which is the main component of a gas distributor. Background technique [0002] Aquaculture, sewage treatment and some chemical production processes often use the oxygen contained in the air to adopt the aeration process. All aeration systems must be equipped with a gas distributor. It has many forms and shapes. The most common gas distributor In order to make a tubular or nozzle-shaped rigid material, holes are evenly distributed on the working surface, and the air is evenly distributed in the liquid through these dense small holes to achieve the purpose of aeration and utilization of oxygen in the air. However, on the rigid material, the aperture of the through hole is relatively large, and the opening ratio is also low. The bubbles generated during the aeration process are relatively large, and the number of bubbles is small. In this way, the contact surface between the gas and the liqui...
