Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater treatment, and in particular to a height-adjustable aeration pipe. Background Technology

[0002] In the field of wastewater treatment, aeration pipes are one of the important pieces of equipment. Their function is to deliver oxygen to the wastewater in the treatment tank to meet the aerobic needs of microorganisms and promote wastewater purification. However, existing aeration pipes have some shortcomings in practical applications. Sludge will continue to accumulate in the treatment tank. The existing aeration pipes have a fixed height and are prone to blockage due to sludge covering, which affects the aeration effect and reduces the wastewater treatment efficiency. Traditional aeration pipes are difficult to set up in a stepped height at different depths to provide stratified oxygen supply according to the oxygen requirements of different depths of wastewater, and cannot fully meet the oxygen demand differences of microorganisms at different levels in the wastewater.

[0003] Based on this, this paper proposes a height-adjustable aeration pipe, which can flexibly change the height of the aeration pipe according to the degree of sludge accumulation, effectively avoiding clogging. This aeration pipe can also be set to a stepped height of different depths to achieve layered oxygen supply, which greatly improves the targeting and effectiveness of sewage treatment and makes up for the shortcomings of existing technologies.

[0027] Example 1

[0028] like Figure 1-7 As shown, a height-adjustable aeration pipe includes a crossbeam 1, on which multiple lifting devices 101 are provided. Each lifting device 101 has a hollow lifting rod 2. The bottom end of the lifting rod 2 is provided with multiple branch pipe joints 201, and an aeration pipe 3 is provided on one side of each branch pipe joint 201.

[0029] In the preferred embodiment, the hollow lifting rod 2 is used to transport oxygen, and the bottom end of the lifting rod 2 is connected to the aeration pipe 3.

[0030] In the preferred embodiment, the lifting device 101 includes a plurality of clamping wheels 102, which are symmetrically arranged on both sides of the lifting rod 2;

[0031] The outer circumference of the clamping wheel 102 is provided with a clamping groove 104, which is used to fit the shape of the lifting rod 2.

[0032] In the preferred embodiment, the outer layer of the lifting rod 2 is covered with a rubber coating. The rubber coating helps to increase the friction between the lifting rod and the clamping groove 104, and can also increase the service life of the lifting rod 2 in the treatment tank.

[0033] In the preferred embodiment, a cleaning column 106 is also provided on the side of the clamping wheel 102 away from the lifting rod 2. The cleaning column 106 is used to clean any debris that may be present in the clamping groove 104.

[0034] In a preferred embodiment, a rotating shaft 103 is provided at the center of the clamping wheel 102, and a lifting motor 107 is provided on one side of the rotating shaft 103. The lifting motor 107 is used to drive the clamping wheel 102 to rotate.

[0035] In the preferred embodiment, a plurality of clamping buckles 105 are provided above the clamping wheel 102. One side of the clamping buckle 105 is in contact with the lifting rod 2, and the other side is provided with a push electric cylinder 108. The clamping buckle 105 is used to clamp the lifting rod 2 for temporary fixation.

[0036] In the preferred embodiment, the aeration pipe 3 includes a permeable pipe 306, which is a porous pipe, and pipe ends 302 are provided at both ends of the permeable pipe 306.

[0037] One end of the pipe 302 is provided with a sealing head 307, and the other end of the pipe 302 is provided with an air pipe connector 301. The air pipe connector 301 is used to connect with the branch pipe connector 201. The outer circle of the vent pipe 306 is provided with an air-permeable aeration membrane 305.

[0038] In the preferred embodiment, a binding groove 304 is provided on one side of the pipe end 302, and a clamp 303 is provided in the binding groove 304. The clamp 303 is used to lock the aeration membrane 305.

[0039] In the preferred embodiment, the clamp 303 is made of titanium alloy.

[0040] The specific usage of a height-adjustable aeration pipe is as follows: First, install the crossbeam 1 at a suitable position above the sewage treatment tank and ensure it is stable. Connect the top of the lifting rod 2 to the oxygen delivery pipe through a hose. Then, tightly connect the air pipe connector 301 of the aeration pipe 3 to the branch pipe connector 201 at the bottom of the lifting rod 2. Since the lifting rod 2 is hollow and connected to the aeration pipe 3, oxygen can be delivered from the lifting rod 2 to the aeration pipe 3.

[0041] When the height of the aeration pipe 3 needs to be adjusted, the lifting motor 107 is started, which drives the rotating shaft 103, thereby causing the clamping wheel 102 to rotate. Since the clamping wheel 102 is symmetrically arranged on both sides and the clamping groove 104 on the outer circumference matches the shape of the lifting rod 2 covered with rubber coating, the lifting rod 2 can move up and down as the clamping wheel 102 rotates. If the lifting rod 2 needs to be temporarily fixed, the push cylinder 108 is activated, pushing the clamping buckle 105 to engage and clamp the lifting rod 2.

[0042] During operation, as the clamping wheel 102 rotates, the cleaning column 106 on the side away from the lifting rod 2 rotates synchronously to clean debris in the clamping groove 104. The aeration pipe 306 of the aeration pipe 3 is a porous pipe. The outer circumference aeration membrane 305 is responsible for aeration. The titanium alloy clamp 303 in the binding groove 304 on one side of the pipe end 302 locks the aeration membrane 305. The sealing head 307 at one end of the pipe end 302 prevents gas leakage and ensures the normal operation of the aeration pipe.

The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
