Description

Technical Field

[0001] The utility model relates to the technical field of aerators, in particular to an environmental protection water treatment aeration device. Background Technique

[0002] The traditional clamp round pipe is inevitably deformed by the welding of the screw head. There is a 1-mm deformation at the screw head, and the angle of a 1-meter-long aeration pipe will tilt by 2-3 cm. It is very difficult to make the four-pipe aerator parallel to the horizontal, thus affecting the aeration uniformity.

[0003] The threaded connection is a combination of steel and plastic. Due to different expansion and contraction coefficients, the aeration pipe will be loosened and air leakage will occur, resulting in the detachment of the aeration pipe, etc. Due to the manufacturing reasons, the thread pitches of the steel and plastic threads cannot be completely matched, resulting in damage to the secondary plastic thread and inability to continue using. Content of the Utility Model

[0004] The utility model provides an environmental protection water treatment aeration device, which solves the disadvantages in the prior art that the threaded connection is a combination of steel and plastic. Due to different expansion and contraction coefficients, the aeration pipe will be loosened and air leakage will occur, resulting in the detachment of the aeration pipe, etc. Due to the manufacturing reasons, the thread pitches of the steel and plastic threads cannot be completely matched, resulting in damage to the secondary plastic thread and inability to continue using.

[0005] The utility model provides the following technical solutions:

At least one distributor inlet and one distributor outlet are provided on the square pipe distributor. A connector is installed on the square pipe distributor. The first circular aeration pipe and the second circular aeration pipe are symmetrically installed on both sides of the connector. The first circular aeration pipe and the second circular aeration pipe are communicated with the connector and the square pipe distributor.

[0007] On both sides of the connector, there are symmetrically arranged limiting peripheral walls. A through hole is surrounded by the limiting peripheral wall, and the through hole is adapted to the outlet of the distributor. The sizes of the first circular aeration pipe and the second circular aeration pipe are adapted to the limiting peripheral walls. A first connection pipe orifice is arranged at the end of the first circular aeration pipe, and a second connection pipe orifice is arranged at one end of the second circular aeration pipe. The first connection pipe orifice and the second connection pipe orifice are fixedly connected by threads, and the outer diameter of the first connection pipe orifice is adapted to the sizes of the outlet of the distributor and the through hole. The lengths of the first connection pipe orifice and the second connection pipe orifice are adapted to the distance between the two side walls of the connector. First water inlets and second water inlets that correspond to each other are respectively arranged on the peripheral walls of the first connection pipe orifice and the second connection pipe orifice. The limiting peripheral walls play a supporting role for the first circular aeration pipe and the second circular aeration pipe, avoiding deflection between the first circular aeration pipe and the second circular aeration pipe and the connector, so that the first circular aeration pipe and the second circular aeration pipe always maintain a vertical state with the square pipe distributor, improving the aeration uniformity; and directly screwing the first connection pipe orifice and the second connection pipe orifice reduces the installation components and lengthens the limiting distance, avoiding deformation and offset caused by stress concentration of the first circular aeration pipe and the second circular aeration pipe during the lifting process of the aerator, reducing the production cost, improving the convenience of installation and disassembly, and at the same time improving the service life.

[0008] As a further improvement of the above solution.

[0009] Preferably, a sealing gasket is arranged between the first circular aeration pipe, the second circular aeration pipe and the two side walls of the connector. The sealing gasket is sleeved on the first connection pipe orifice, improving the sealing performance between the first circular aeration pipe, the second circular aeration pipe and the connector.

[0010] Preferably, internal thread is arranged on the inner side of the front end of the first connection pipe orifice, and external thread is arranged on the outer side of the rear end of the second connection pipe orifice. The internal thread is arranged at the end, and the external thread is arranged at the rear end, making the socketing distance between the first connection pipe orifice and the second connection pipe orifice long enough, improving the shear resistance while improving the production convenience.

[0011] Preferably, the square pipe distributor is provided with one distributor inlet and two distributor outlets, or the square pipe distributor is provided with two distributor inlets and four distributor outlets.

[0012] Preferably, an intake main pipe is evenly installed on the water surface, and the left-right distance of the intake main pipe is 1500 - 3000 mm.
