Description

Technical Field

[0001] This utility model relates to supporting equipment for sewage treatment ponds, and more particularly to an aeration branch pipe lifting device in a sewage treatment pond. Background Technology

[0002] In wastewater treatment units, the biological system unit is the most widely used secondary treatment unit, and the aeration equipment in the aeration tank is one of the key pieces of equipment for the aerobic reaction in the biological system.

[0003] The aeration equipment includes aeration branch pipes vertically installed in the aeration tank. The bottom of the aeration branch pipes is connected to an aeration hose with aeration holes. The aeration equipment also includes an aeration blower, which is connected to the upper end of the aeration branch pipes through an air supply pipe. Specifically, the air supply pipes and the aeration branch pipes are detachably connected by a flange.

[0004] When in use, the air supply pipe of the aeration blower sends air to the aeration branch pipe, then through the aeration branch pipe to the aeration hose, and finally through the aeration hole into the aeration tank.

[0005] The existing sewage tanks have the following problems: depending on the operating conditions, the aeration branch pipes need to be inspected without emptying the tank. In practice, the aeration branch pipes need to be lifted from the water to the top of the tank. Currently, the depth of the sewage tanks is about 5 to 7 meters, which requires a relatively high lifting height. In addition, the aeration branch pipes are made of stainless steel and are quite heavy. The traditional method of simply relying on manual labor to lift the aeration branch pipes is not only laborious and cumbersome, but also dangerous for the operators. Utility Model Content

[0006] The purpose of this invention is to provide a device for lifting aeration branch pipes in a sewage tank, which facilitates the lifting of aeration branch pipes.

[0007] The technical solution of the aeration branch pipe lifting device in the sewage tank according to this utility model is as follows: A device for lifting aeration branch pipes in a sewage tank includes a support frame that is placed on top of the sewage tank during use. The top of the support frame is provided with a first reversing pulley and a second reversing pulley. The support frame is provided with a first winch and a second winch that are independently arranged. The first winch and the second winch are electric winches or self-locking hand-cranked winches. A first pull rope is wound on the first winch and a second pull rope is wound on the second winch. The end of the first pull rope away from the first winch is wound around the first reversing pulley and then connected to a first pipe clamp for connecting to the aeration branch pipe. The end of the second pull rope away from the second winch is wound around the second reversing pulley and then connected to a second pipe clamp for connecting to the aeration branch pipe.

[0008] Furthermore, the device support includes a support top plate, and three support legs spaced apart circumferentially are fixed at the bottom of the support top plate. The first winch is mounted on one of the support legs, and the second winch is mounted on the other support leg.

[0009] Furthermore, the first reversing pulley and the second reversing pulley are mounted on the top plate of the support.

[0010] Furthermore, the pulley axes of the first and second reversing pulleys are set horizontally, and the first and second reversing pulleys are rotatably mounted on their respective pulley frames. The bottom of the top plate of the bracket is provided with a pulley frame support corresponding to the pulley frame. Each pulley frame is rotatably mounted on its corresponding pulley frame support, and the rotation axis of the pulley frame extends in the vertical direction.

[0011] Furthermore, the first pipe clamp includes a first U-shaped flap and a second U-shaped flap that are detachably connected by bolts. The first U-shaped flap and the second U-shaped flap are used to clamp onto both sides of the aeration branch pipe. A rigid connecting rod is rotatably mounted on the first U-shaped flap, and a first pull rope is connected to the end of the rigid connecting rod away from the first U-shaped flap.

[0012] The beneficial effects of this technical solution are as follows: When it is necessary to raise the aeration branch pipe, the device support is placed on the top of the sewage treatment tank. The first pipe clamp is connected to the aeration branch pipe, and the second pipe clamp is connected to the aeration branch pipe. The first and second pipe clamps are arranged at different heights. Then, the connection between the air supply pipe and the aeration branch pipe is disconnected. The first winch raises the height of the aeration branch pipe through the first pipe clamp. After the aeration branch pipe rises to a certain height, the second winch tightens the second rope to position the aeration branch pipe at that height. Then, the first pipe clamp is released, the height of the first pipe clamp is lowered, and the first pipe clamp is tightened again. The height of the aeration branch pipe is raised again using the first winch. This cycle is repeated to achieve step-by-step raising of the aeration branch pipe. The second winch, in conjunction with the second pipe clamp, ensures the safety of adjusting the height of the first pipe clamp, ensuring that the aeration branch pipe can be raised safely.

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0017] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0018] A specific implementation of the aeration branch pipe lifting device in a sewage tank according to this utility model is as follows: Figures 1-5 As shown: Before introducing the wastewater treatment tank aeration branch pipe lifting device of this utility model, a brief introduction to the existing wastewater treatment tank 15 is given first. The wastewater treatment tank 15 includes a tank body, in which a vertically arranged aeration branch pipe 17 is installed. The bottom of the aeration branch pipe 17 is connected to an aeration hose 16, and the upper end of the aeration branch pipe is detachably connected to an air supply pipe 18 via a flange. When maintenance of the aeration branch pipe is required, the connection between the aeration branch pipe 17 and the air supply pipe 18 needs to be disconnected, and the aeration branch pipe 17 (along with the aeration hose at the bottom) is lifted up from the wastewater treatment tank.

[0019] The aeration branch pipe lifting device in the sewage tank includes a device support 1 that is placed on top of the sewage tank body during use. The device support 1 includes a support top plate 4, and three support legs 2 that are spaced apart along the circumference are fixed at the bottom of the support top plate 4.

[0020] The bottom of the support top plate 4 is provided with a first reversing pulley 5 and a second reversing pulley 6. The device support is provided with a first winch 11 and a second winch 10, which are independently arranged. Specifically, the winch bracket of the first winch 11 is set on one of the support legs 2, and the winch bracket of the second winch 10 is set on the other support leg. In this embodiment, the first winch and the second winch are self-locking hand-cranked winches (or electric winches).

[0021] A first pull rope 3 is wound on the first winch 11, and a second pull rope 7 is wound on the second winch 10. The end of the first pull rope 3 away from the first winch 11 is wound around the first reversing pulley and then connected to a first pipe clamp 8 for connecting to the aeration branch pipe. The end of the second pull rope 7 away from the second winch is wound around the second reversing pulley and then connected to a second pipe clamp 9 for connecting to the aeration branch pipe.

[0022] In this embodiment, the pulley axes of the first reversing pulley 5 and the second reversing pulley 6 are horizontally arranged. The first reversing pulley 5 and the second reversing pulley 6 are rotatably mounted on their respective pulley frames 13. The bottom of the bracket top plate 4 is provided with a pulley frame support 14 corresponding to the pulley frame 13. Each pulley frame 13 is rotatably mounted on the corresponding pulley frame support 14. The rotation axis of the pulley frame 13 extends in the vertical direction.

[0023] The first and second pipe clamps have the same structure. Only the structure of the first pipe clamp will be described in detail. The first pipe clamp includes a first U-shaped flap 19 and a second U-shaped flap 10 that can be detachably connected by bolts. The first U-shaped flap and the second U-shaped flap are used to clamp onto both sides of the aeration branch pipe. A rigid connecting rod 12 is rotatably mounted on the first U-shaped flap. The end of the rigid connecting rod away from the first U-shaped flap is connected to the first pull rope.

[0024] When maintenance is required on the aeration branch pipes, such as Figure 3As shown, the support frame of the lifting device is placed on top of the sewage treatment tank. The first pipe clamp is connected to the aeration branch pipe, and the second pipe clamp is also connected to the aeration branch pipe. The first pipe clamp is located below the second pipe clamp. The connection between the aeration branch pipe and the air supply pipe is disconnected. The first winch lifts the aeration branch pipe upwards using the first pull rope. When the lifting limit for this operation is reached, the second winch is tightened. The second pull rope uses the second pipe clamp to position the aeration branch pipe at that height. Then, the first pipe clamp is released, and its height is lowered. The first winch is used to lift the aeration branch pipe again. When the aeration branch pipe reaches the corresponding height for the second time, the position of the second pipe clamp needs to be adjusted. The second winch and the second pipe clamp are used to limit the aeration branch pipe to that height. Then, the height of the first pipe clamp is lowered again. This cycle is repeated to lift the aeration branch pipe step by step. In this embodiment, the first U-shaped petals and the second U-shaped petals form a passageway for the aeration branch pipe to pass through. When the first U-shaped petals and the second U-shaped petals are arranged horizontally, their inner walls are spaced apart from the outer periphery of the aeration branch pipe. At this time, the first pipe clamp can be easily adjusted to adjust its height relative to the aeration branch pipe. When the first pull rope applies upward tension, the first pull rope applies tension to the first pipe clamp through the rigid connecting rod. The first pipe clamp will be in a state where the left side is higher than the right side. At this time, the inner walls of the first U-shaped petals and the second U-shaped petals will contact the outer periphery of the aeration branch pipe, and the first pull rope can raise the height of the aeration branch pipe through the first pipe clamp.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
