Description

Technical Field

[0001] The utility model relates to the technical field of aeration structures, in particular to a liftable aerator which is easy to assemble and replace. Background Art

[0002] Aerator is an aeration device for adding oxygen to sewage. It is mainly used in sewage aeration treatment systems and in new urban sewage treatment.

[0003] The existing aeration head has a fixed installation height, and cannot autonomously adjust the height of the aeration head according to the water level depth of the sewage pool, which makes the installation method of the aeration head less applicable.

[0004] For this reason, we propose a liftable aerator that is easy to assemble and replace to solve the existing problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the background technology and to provide a liftable aerator which is easy to assemble and replace.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a liftable aerator that is easy to assemble and replace, comprising a main pipe, a connector, a vertical shell and a retaining frame, the main pipe is provided with a connector, the outer wall of the main pipe is installed with the vertical shell, the vertical shell is lifted and installed inside the retaining frame by a driving mechanism, and an aeration pipe is provided at the bottom end of the vertical shell.

[0007] Preferably, a mounting head is installed at the bottom end of the vertical shell, a hose is installed at the top end of the mounting head, and the other end of the hose is installed on the connecting head;

[0008] The aeration pipe is fixed to the bottom end of the mounting head through a flange.

[0009] Preferably, the inner wall of the retaining frame is symmetrically provided with sliding blocks, the outer wall of the vertical shell is provided with sliding grooves adapted to the sliding blocks, and the sliding blocks are slidably installed in the sliding grooves.

[0010] Preferably, the driving mechanism is composed of a rack, a base, a limit rod, a gear and a rotating rod;

[0011] The rack is mounted on the outer wall of the vertical shell, and the base is fixed on the outer wall of the retaining frame;

[0012] The limiting rod is movably inserted into the upper end of the base, the rotating rod is threadedly installed on the lower end of the base, the end of the limiting rod is fixed on the retaining frame, and the end of the rotating rod is rotatably installed on the retaining frame;

[0013] The gear is rotatably mounted on the base, and the gear and the rack are meshed with each other;

[0014] The outer wall of the base is provided with a protrusion by means of a bolt, and a pin is threadedly provided on the protrusion;

[0015] Pin grooves are equidistantly arranged on the shaft end of the gear protruding from the base, and one end of the pin rod is movably inserted into the pin groove.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] During use, the utility model can fix the structure on the main pipe of the aeration system pipeline, and install a corresponding number of aeration pipes according to the number of connectors provided on the main pipe. The compressed air flowing in the main pipe enters the hose through the connector and then enters the aeration pipe through the hose. The gas is aerated under the water level through the micropores on the aeration pipe.

[0018] During this process, when the height of the aeration pipe needs to be adjusted, the gear can be rotated, and the meshing action between the gear and the rack causes the vertical shell to be raised and lowered on the retaining frame, thereby controlling the height of the aeration pipe.

[0019] After the height is determined, the pin rod is controlled to rotate so that the pin rod extends into the pin groove at the end of the gear shaft, thereby positioning the gear and preventing the gear from self-rotating;

[0020] Furthermore, when the structure needs to be replaced, the rotating rod can be rotated, and the rotating rod and the base are meshed, and the base is limited by the limiting rod and does not deflect. At this time, the base drives the gear away from the rack, thereby facilitating the upward withdrawal of the stand shell;

[0021] The utility model is easy to assemble and replace and can be lifted through structural coordination. The installation height of the aeration head is adjustable, and the height of the aeration head can be adjusted autonomously according to the water level depth of the sewage pool, thereby increasing the applicability of the installation method of the aeration head.
