Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to a position limiting and lifting device for an aeration hose. Background Art

[0002] During sewage treatment, it is necessary to aerate the sewage. Aeration is a means of making air and water come into strong contact with each other. Its purpose is to dissolve oxygen in the air into the water. The aeration tube aeration device is a device for treating sewage in the pool. Aeration micropores are opened on the aeration hose, and the aeration hose is placed at the bottom of the pool. Air is introduced into the aeration hose, and the air is exposed upward from the aeration micropores to form aeration.

[0003] At present, both ends of the aeration hose are generally connected to a metal distributor. When the aeration hose at the bottom of the pool needs to be replaced, it is only necessary to lift the distributor upward to pull the aeration hose out of the bottom of the pool. However, the distributor is prone to shaking around during the lifting process, causing the aeration hose to be entangled or scratched.

[0004] After searching, the Chinese patent with authorization announcement number CN215798765U discloses an aeration tube lifting device. This structure sets a guide rail on one side of the distributor, so that when the distributor is lifted or lowered, it can slide up and down along the guide rail, which is convenient for disassembly and installation of the aeration device.

[0005] However, in actual use, the lifting method of this structure is inconvenient, and the operator is required to tie the rope to the distributor and apply upward pulling force to lift the aeration pipe. This is not only time-consuming and labor-intensive, but also increases the labor intensity and safety risks of the operator. Moreover, if the lifting force is insufficient during the lifting process, there is a risk that the aeration pipe may accidentally slide down. In view of this, the utility model proposes a limiting lifting device for the aeration hose. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a position limiting and lifting device for an aeration hose to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions: a position limiting and lifting device for an aeration hose, comprising two distributors and an aeration pipe installed between the two distributors, the top of the distributor being connected to a connecting branch pipe, and a blast branch pipe being provided on the top of the connecting branch pipe.

[0008] Preferably, a lifting structure is provided on the opposite side of the two distributors, and the lifting structure includes a vertically installed screw and a guide rod, the screw is located on one side of the guide rod, the bottom ends of the screw and the guide rod are provided with a fixing plate, and the top end of the screw is provided with a support plate, a motor is installed on the support plate, and the outside of the screw and the guide rod are respectively provided with a threaded block and a guide block, and the threaded block and the guide block are respectively connected to the corresponding distributors, the motor is fixedly installed on the top of the support plate, and the output end of the motor is fixedly connected to the screw, the threaded block is threadedly connected to the outside of the screw, and the guide block is slidably connected to the guide rod.

[0009] Preferably, two air outlet pipes are connected on the side wall of the distributor, and flanges and sealing rings are provided at the connection between the air outlet pipe and the aeration pipe, and at the connection between the blast branch pipe and the connecting branch pipe. The sealing ring is located at the connection between the two flanges.

[0010] Preferably, a plurality of mounting holes are provided on the surface of the fixing plate, and fastening bolts are threadedly installed inside the plurality of mounting holes.

[0012] Technical effects and advantages of this utility model:

[0013] 1. By setting up a lifting structure, the motor drives the screw to rotate so that the threaded block extends upward, and the threaded block drives the distributor and the aeration pipe to lift. The guide block and the guide rod are used for sliding limit, thereby ensuring the stability of the aeration pipe during lifting and avoiding deviation and shaking. In addition, during the lifting period, due to the thread restriction of the threaded block and the screw, the risk of the aeration pipe sliding down during lifting is avoided. This makes it convenient to lift the aeration pipe out of the sewage pool for maintenance without emptying the sewage pool, and it is also convenient to install the aeration pipe in the sewage pool.

[0014] 2. Connect the aeration pipe and the air outlet pipes on the two distributors through the flange, and connect the blast branch pipe to the connecting branch pipe on the distributor at the same time, so as to achieve the installation and disassembly of the blast branch pipe and the aeration pipe, and the T-shaped clamping block slides and clamps inside the T-shaped clamping groove opened by the clamping plate, and the clamping plate and the two T-shaped clamping blocks are fixed to the distributor, threaded block and guide block respectively, which can facilitate the installation and disassembly of the distributor with the threaded block and guide block respectively, thereby facilitating the disassembly and maintenance of the aeration device.
