DETAILED DESCRIPTION​​

[0021] In order to make the technical means of the utility model more clearly understood, and can be implemented according to the content of the specification, the specific embodiments of the utility model are further described in detail below, the following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

[0022] Referring to the accompanying drawings Figures 1-5 As shown in the drawings, the adjustable aperture multi-section aeration assembly of the embodiment one comprises an inner tube 1 for connecting the output end of the aeration pump, an outer tube 2 movably arranged on the outer wall of the inner tube 1, a plurality of aeration holes 11 opened on the inner tube 1, and a plurality of adjusting holes 21 opened on the outer tube 2 and corresponding to the aeration holes 11, which can adjust the aperture size of the aeration holes 11.

[0023] When the outer tube 2 rotates, the adjusting holes 21 can be aligned with the aeration holes 11, so that the aeration holes 11 have the maximum aperture, which can be used in the area with high organic matter concentration of the water inlet, and when it is needed to refine the bubbles, the outer tube 2 is rotated, and the aeration holes 11 are covered by the adjusting holes 21, so as to reduce the aperture of the aeration holes 11, achieve the effect of bubble refinement, and make the aperture of the aeration assembly adjustable, which can be dynamically adjusted according to the water quality, water quantity or processing stage, improve the aeration efficiency, reduce the energy consumption, and the oxygen demand difference of different areas in the aeration tank is small.

[0024] The convex ring 22 extends outward along the outer ring surface of the outer tube 2, and the inside of the convex ring 22 is hollow; a limiting mechanism is arranged at the hollow position of the convex ring 22, which can limit the position of the outer tube 2 after adjustment; and a connecting assembly 12 is arranged at one end of the inner tube 1.

[0025] Since the aeration pump is always outputting gas or gas-water mixture, it has a certain impact force, and when it is needed to refine the bubbles, if the outer tube 2 is not limited, the outer tube 2 will rotate and expand the aperture by itself, and the rotation of the outer tube 2 can be prevented by the limiting assembly to maintain the small aperture.

[0026] The connecting assembly 12 can connect a plurality of inner tubes 1 to form a multi-section structure, which is convenient for large-scale laying in the aeration tank, and is convenient for transportation and transportation after disassembly.

[0027] Further, the outer ring surface of the inner tube 1 is provided with an annular groove 13, the inside of the annular groove 13 is provided with a bearing 14, the outer ring surface of the outer ring of the bearing 14 is fixedly connected with the outer tube 2, and the inner ring surface of the inner ring of the bearing 14 is fixedly connected with the inner tube 1.

[0028] The outer tube 2 can rotate freely after the inner tube 1 is fixed through the bearing 14, which is convenient for adjusting the aperture of the aeration holes 11.

[0029] The annular groove 13 can reduce the gap between the inner tube 1 and the outer tube 2, and improve the sealing strength.

[0030] Further, a plurality of sealing grooves 15 are arranged on the connection between the outer ring surface of the inner tube 1 and the inner ring surface of the outer tube 2.

[0031] The sealing grooves 15 and the sealing strips 16 can increase the sealing performance, so that the gas or gas-liquid mixture can only overflow from the adjusted hole diameter.

[0032] Further, the limiting mechanism comprises: a reverse tooth 23 arranged at the top of the inner cavity of the convex ring 22; an expansion ring 3 arranged on the outer ring surface of the inner tube 1 and located in the inner cavity of the convex ring 22, wherein the outer ring surface of the expansion ring 3 is uniformly and spacedly provided with a plurality of receiving grooves 31; and a resisting piece 32 capable of being received into the receiving grooves 31, wherein the resisting piece 32 is rotationally connected to the receiving grooves 31 through a shaft.

[0033] When the outer tube 2 rotates counterclockwise, the resisting piece 32 can be pushed into the receiving groove 31, so that the outer tube 2 can rotate smoothly counterclockwise, and the hole diameter of the aeration hole 11 can be adjusted by clockwise rotation.

[0034] Further, the receiving groove 31 is internally provided with a reset spring 33, and the other end of the reset spring 33 is fixedly connected with the resisting piece 32.

[0035] The reset spring 33 can support the resisting piece 32, and provide a certain damping feeling when the resisting piece 32 is extruded by the reverse tooth 23. After the resisting piece 32 is reset by the reset spring 33, the reverse tooth 23 can be limited, so that the reverse tooth 23 cannot rotate clockwise.

[0036] Further, the reverse tooth 23 and the resisting piece 32 are both triangularly arranged. When the outer tube 2 rotates counterclockwise, the reverse tooth 23 will extrude the resisting piece 32 into the receiving groove 31. When the outer tube 2 rotates clockwise, the reverse tooth 23 will be blocked by the resisting piece 32.

[0037] In actual use, the reverse tooth 23 and the resisting piece 32 can be arranged more and the distance between them can be smaller, so that the hole diameter of the aeration hole 11 has more adjustment schemes.

[0038] Further, the receiving groove 31 is internally provided with an arc-shaped slide 34, and the resisting piece 32 is provided with a sliding block 35 slidably connected with the slide 34.

[0039] The slide 34 and the sliding block 35 can limit the resisting piece 32, so that the resisting piece 32 cannot rotate to the other side due to the resistance of the reverse tooth 23.

[0040] Further, the outer ring surface of both ends of the connecting assembly 12 is provided with an external thread, and the both ends of the inner tube 1 are provided with an internal thread matched with the external thread.

[0041] The two ends of the inner tube 1 can be connected to the connecting assembly 12, and then another inner tube 1 can be connected through the connecting assembly 12, so as to form a multi-section structure.
