Problems solved by technology
The biggest disadvantage of this structure is that the precision of the mold is high, the size is difficult to control during injection molding, and the matching gap between the inner and outer diameters of the plum blossom shape is uneven during assembly, resulting in gaps after the support and the straight tube are bonded, which is easy to leak during aeration. gas

Embodiment Construction
[0017] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0018] Such as image 3 , Figure 4 As shown, the support tube of the membrane tube type microporous aerator according to the present invention includes a straight tube body 4 and supports 5-1 and 5-2 at the left and right ends, as shown in Figure 4 As shown, the outer peripheral surface of the straight tube body 4 is radially evenly distributed with a number of shallow-bottomed grooves 6, and the grooves 6 run through the entire length of the tube body along the axis of the straight tube body 4, for example, for the outer diameter D of 63mm The support pipe made of UPVC material has a wall thickness t of 3.5mm, and the groove depth of the groove 6 is 0.6mm. Because the groove depth of the groove 6 is relatively shallow, it basically does not affect the thickness, nor does it affect the forming and strength. Therefore, the inner diamete...

The invention discloses a supporting tube of a diaphragm tube type micro-pore aerator, which comprises a straight tube barrel and support seats which are arranged at the left end and the right end of the barrel, wherein a plurality of grooves with shallow bottoms are uniformly distributed on the peripheral surface of the straight tube barrel in a radiating way, the grooves run through the whole barrel length along the axis of the straight tube barrel, the inner diameter of the straight tube barrel is in a complete-circle shape, the peripheries of matched sections of the support seats at the left end and the right end are in the complete-circle shape, and the circle shapes inserting into the supporting tube, of two ends of the straight tube barrel are in inner diameter assembling and sealing. According to the invention, the support tube and the support seats are in periphery matching, the structural design is reasonable, the size and the accuracy can be controlled easily during injection molding, a matching clearance is uniform during assembling, and the sealing performance is good; the supporting tube is not easy to deform, so that the service life is long; and air pressure is approximate during aeration, sizes of bubbles are approximate, and an air curtain is uniform and compact in distribution, so that the efficiency of aeration and oxygen enhancement can be effectively improved.
Description
technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a support tube of a membrane tube type microporous aerator. Background technique [0002] Aerators are commonly used in water treatment equipment for environmental protection projects to oxygenate the water in the reaction tank. Diaphragm tube microporous aerator is a commonly used aerator. The diaphragm is made of rubber material with tiny self-closing holes. The diaphragm is wrapped on the middle support tube and tightened by hoops at both ends. . When working, the air blower is used to transport the air through the air pipeline to the aerator located at the bottom of the pool. The compressed air enters between the support tube and the diaphragm, and the micropores on the surface of the diaphragm will automatically open under the air pressure while the diaphragm expands. The air diffuses out in the form of bubbles, dissolves oxygen into the water at the air-l...
