[0008] Further, the clamping assembly comprises two clamps, the bottom ends of the two clamps are connected through a hinge shaft, a plurality of connecting pieces are fixed to the top ends of the two clamps, the plurality of connecting pieces on the two clamps are arranged alternately, and the plurality of connecting pieces are connected through a latch.

[0009] Further, an installation disc is fixed on the clamp, an air inlet pipe in communication with the pipeline is installed on the installation disc, the other end of the air inlet pipe is connected with a connecting head fixed on the aeration pipe, and a plurality of air inlet holes in communication with the groove are formed on the connecting head.

[0010] Further, the cross section of the aeration pipe is arc-shaped.

[0011] The utility model has the advantages of:

[0012] The utility model discloses a recess and the recess's upper installation " arc " membrane piece with " arc " shape on the aeration pipe are set up, make the aeration pipe can with the curved surface form carry out aeration treatment, the gas that explodes spreads to all around and forms the bubble after entering the inside of liquid, make the bubble that explodes is more dispersed, reduce the situation that the big bubble is formed because the bubble gathers, thereby promote the use effect of the half -pipe type aerator.

[0019] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art belong to the scope of protection of the utility model.

[0020] A half -pipe type aerator, including installing the clamping assembly 2 on the pipeline 1, both sides of the clamping assembly 2 are installed with aeration pipe 3, and the section of aeration pipe 3 is " arc " shape setting.

[0021] Specifically: the clamping assembly 2 includes two two clamps 21, and the bottom end of two clamps 21 is connected by hinged axle 22, so that two clamps 21 can rotate around hinged axle 22, and the top end of two hinged axles 22 is fixed with a plurality of connecting pieces 23, and the plurality of connecting pieces 23 on two hinged axles 22 are staggered, and the plurality of connecting pieces 23 are connected by the same bolt 24, and the bolt 24 is set to play the role of restraining two clamps 21, to prevent the phenomenon that the clamp 21 shakes on the pipeline 1.

[0022] Need to explain: each clamp 21 are fixed with "semicircular shape" mounting disc 25, and the mounting disc 25 is fixed with the air inlet pipe 26, and the air inlet pipe 26 can extend to the inside of the pipeline 1, the other end of the air inlet pipe 26 is screwed with the connector 27, and the connector 27 is fixed in one end of the aeration pipe 3.

[0023] The upper part of the aeration pipe 3 is provided with "arc" shaped groove 4, need to explain: the air inlet pipe 26 is provided with a plurality of air inlet communicated with the groove 4, and the groove 4 is installed with "arc" shaped diaphragm 5, and the diaphragm 5 is installed to the upper part of the groove 4, forming an aeration channel with "arc" shaped cross section, through the setting of "arc" shaped aeration channel and "arc" shaped diaphragm 5, the aeration pipe 3 can be curved surface form aeration treatment, the gas explosion into the liquid inside, form bubbles, so that the bubble is more dispersed, reduce the phenomenon of large bubble formation due to the combination of multiple bubbles, so as to improve the aeration effect.
