Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, and more specifically, to a liftable aeration device. Background Art

[0002] Aerators, as key equipment in the sewage treatment process, are usually installed at a certain depth in the sewage treatment tank. Their main function is to increase the oxygen content in the sewage by introducing fine air into the sewage, thereby facilitating the growth and reaction of aerobic microorganisms and achieving efficient sewage treatment.

[0003] However, since the aerator is installed inside the pool, it is easily affected by small particles in the sewage. These small particles may cause the aeration holes to be blocked, which in turn makes the aerator unable to aerate normally and affects its normal use. Therefore, it is particularly important to perform regular maintenance and inspection on the aerator.

[0004] During the maintenance and overhaul of the aerator, the water in the sewage pool must first be drained to expose the aerator to the water surface so that the operator can perform maintenance work. However, this step will cause the treatment pool to be unable to be used normally during the maintenance period, which will bring certain inconveniences to the sewage treatment work.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] This embodiment discloses a liftable aeration device, referring to Figure 1 , Figure 2 , Figure 3 As shown, it includes a main pipeline 1, which is installed above the aeration tank. A plurality of aeration components are connected to the lower part of the main pipeline 1 through a connector 2 to form a plurality of air supply points, which can perform aeration treatment in the aeration tank.

[0027] Reference Figure 1As shown, the aeration assembly includes an air supply pipe 3 and an aerator 4, the upper end of the air supply pipe 3 is connected to the joint 2, the lower end of the air supply pipe 3 is connected to the aerator 4, and the aerator 4 is suspended below the main pipeline 1 through the air supply pipe 3. The aerator 4 can be suspended in the water in the pool body, and the aerator 4 can spray fine bubbles to achieve aeration.

[0028] The connector 2 includes a connector 1 21 and a connector 2 22, and a detachable connection structure is adopted between the connector 1 21 and the connector 2 22, so that the air supply pipe 3 and the main pipe 1 can be disassembled by disassembling the connector 2. After disassembly, the aeration assembly can be lifted up as a whole, so that the aerator 4 can be inspected and maintained, which is convenient for operation.

[0029] The first connector 21 is fixedly connected to the lower side of the main pipeline 1, and the second connector 22 is connected to the upper end of the gas supply pipe 3, and the first connector 21 and the second connector 22 form a detachable connection structure. Specifically, a threaded connection structure can be used between the first connector 21 and the second connector 22, and a seal can be achieved through a seal; or, the first connector 21 and the second connector 22 can also be connected by a flange, and both can be disassembled and connected.

[0030] Furthermore, the main pipeline 1 is made of a hard metal pipeline to play a supporting role, while the air supply pipe 3 is a soft pipe that can be elastically deformed and bent, and the air supply pipe 3 can be lifted and stored and adjusted by bending.

[0031] Since the air supply pipe 3 can be bent, the air supply pipe 3 can be bent upward without removing the joint 2 by utilizing its own flexibility, thereby lifting the aerator 4 in the tank body upward, thereby also enabling the aerator 4 to be inspected and maintained.

[0032] Two connecting rods 5 are fixedly connected to the lower side of the joint 2. The two connecting rods 5 are parallel to each other and extend downward. The connecting rod 5 is provided with an adjustment seat 6. The adjustment seat 6 is provided with a through hole 61, and the air supply pipe 3 is provided through the through hole 61. A locking mechanism 8 is provided on the lower side of the adjustment seat 6, and the locking mechanism 8 can be used to fix the adjustment seat 6. By lifting the air supply pipe 3, the air supply pipe 3 can be bent and stored between the joint 2 and the adjustment seat 6, and then the aerator 4 can be raised and lowered, so that the height of the aerator 4 can be in an appropriate position, and then it can be adjusted according to the actual situation. On the one hand, the aerator 4 can be kept at a certain depth in the pool body, and on the other hand, it can also avoid the aerator 4 being too low and too close to the bottom of the sedimentation, which makes the aerator 4 easy to be blocked.

[0033] The adjustment seat 6 is provided with two connection holes 62, and the positions of the two connection holes 62 correspond to the positions of the connecting rod 5, and the connecting rod 5 is arranged through the connection holes 62. Through the mutual guidance and limiting between the connecting rod 5 and the connection hole 62, the adjustment seat 6 can be adjusted up and down along the connecting rod 5, and then the height position of the adjustment seat 6 can be changed. An external thread is arranged on the outer periphery of the connecting rod 5, and the connecting rod 5 is threadedly connected with a nut 7, which is located at the lower side of the adjustment seat 6. The adjustment seat 6 can be supported by the nut 7, and the height of the adjustment seat 6 can be adjusted by adjusting the position of the nut 7 on the connecting rod 5.

[0034] Reference Figure 2 As shown, during the upward adjustment of the adjustment seat 6, the adjustment seat 6 can drive the air supply pipe 3 to move upward, while the length between the adjustment seat 6 and the joint 2 remains unchanged, the positions of the adjustment seat 6 and the joint 2 are close to each other, and the air supply pipe 3 will form an arc-shaped buffer portion 31, which can partially accommodate the air supply pipe 3 between the adjustment seat 6 and the joint 2, thereby adjusting the height position of the suspension of the aerator 4 and adjusting the aerator 4 to an appropriate height position.

[0035] Reference Figure 3 As shown, the locking mechanism 8 includes a locking ring 81, and the locking ring 81 is connected to the adjustment seat 6, so that the locking mechanism 8 can be linked with the adjustment seat 6. The locking ring 81 is sleeved on the outer periphery of the air supply pipe 3, and a plurality of locking plates 9 are distributed in an annular manner on the inner periphery of the locking ring 81, and the locking plates 9 have a certain elasticity. The locking plate 9 includes a fixed end 91 and a suspended end 92, and the fixed end 91 is connected to the inner periphery of the locking ring 81, and the connection is achieved through the fixed end 91, so that the locking plate 9 and the locking ring 81 are connected to each other; the suspended end 92 faces the inner periphery of the locking ring 81, and the suspended end 92 is against the outer wall of the air supply pipe 3, and a certain friction force is formed between the suspended end 92 and the air supply pipe 3.

[0036] An annular protrusion 63 is fixedly connected to the lower side of the adjustment seat 6, and the annular protrusion 63 is sleeved outside the air supply pipe 3. The through hole 61 of the adjustment seat 6 extends into the annular protrusion 63, and the air supply pipe 3 passes through the adjustment seat 6 and the annular protrusion 63 in sequence. An external thread is provided on the outer periphery of the annular protrusion 63, and an internal thread is provided on the inner periphery of the locking ring 81, and the external thread and the internal thread are adapted to each other. During installation, the locking ring 81 is sleeved outside the annular protrusion 63, and a threaded connection is achieved through an adapted thread, thereby enabling the connection between the locking ring 81 and the adjustment seat 6.

[0037] A second annular protrusion 82 is fixedly connected to the inner circumference of the locking ring 81 , and the locking piece 9 is located between the first annular protrusion 63 and the second annular protrusion 82 .

[0038] The locking piece 9 is an arc-shaped structure, which is arc-shaped and bulges toward the direction of the annular protrusion 1 63. The locking piece 9 is elastic. The suspended end 92 of the locking piece 9 is tilted toward the lower side. When the annular protrusion 1 63 and the annular protrusion 2 82 are close to each other, the annular protrusion 1 63 and the annular protrusion 2 82 can press the arc-shaped piece in the middle up and down, and the annular protrusion 1 63 can push the locking piece 9 to elastically straighten, so that the suspended end 92 can extend toward the direction of the air supply pipe 3, increase the pressure between the suspended end 92 and the outer wall of the air supply pipe 3, and lock and fix the air supply pipe 3 through greater pressure and friction.

[0039] In addition, when the annular protrusion 1 63 and the annular protrusion 2 82 are close to each other, the middle locking plate 9 produces elastic deformation, thereby forming an elastic effect in the up and down directions on the annular protrusion 1 63 and the annular protrusion 2 82, thereby increasing the thread pressure between the adjustment seat 6 and the locking ring 81, thereby preventing the thread from loosening.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
