Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment, and more specifically, it relates to a wastewater treatment sedimentation tank. Background Technology
[0002] A wastewater treatment sedimentation tank is a device used to physically remove suspended solids from wastewater. It mainly separates solid particles through the principle of sedimentation. Horizontal flow sedimentation tanks are a type of wastewater treatment sedimentation tank.
[0003] The existing horizontal flow sedimentation tank includes a tank body, a sludge hopper at the bottom of the tank body, and a sludge scraper inside the tank body. The sludge scraper is driven by a chain to move on the bottom of the tank body, thereby scraping the sludge at the bottom of the tank body into the sludge hopper. A suction pipe is installed inside the sludge hopper, which can suck out the sludge from the sludge hopper.
[0004] To ensure the stability of the suction pipe, the suction head is fixed in position within the sludge hopper. This prevents the suction head from moving during suction, ensuring efficient sludge removal. However, the sedimentation tank requires regular maintenance, necessitating the scraping of sludge from the inner wall of the sludge hopper. This process is typically done manually. However, because the suction head cannot be moved, the sludge can only be pushed downwards towards the suction head, which is quite laborious.
[0005] Therefore, a new solution is needed to address this problem. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sewage treatment sedimentation tank.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sewage treatment sedimentation tank, including a tank body and a sludge hopper located at the bottom of the tank body, a suction pipe with one end extending into the sludge hopper is provided on an inner wall of the tank body, an upper fixing sleeve is fixedly connected to the inner wall of the tank body, a lower fixing sleeve is fixedly connected to the inner peripheral wall of the sludge hopper, the upper fixing sleeve and the lower fixing sleeve are respectively fitted onto the two ends of the suction pipe, the portion of the suction pipe located between the upper fixing sleeve and the lower fixing sleeve is bent toward the inner wall of the sludge hopper, and one end of the suction pipe can be detached from the lower fixing sleeve.
[0008] The present invention is further configured such that: a conformal ring is fixedly connected to the outer peripheral wall of the suction pipe, the inner diameter of the conformal ring is equal to the outer diameter of the suction pipe, and the suction pipe is bent by limiting and fixing the conformal ring to the inner wall of the mud hopper.
[0009] The present invention is further configured such that: a fixing belt and a fixing seat are fixedly connected to the inner wall of the mud bucket, one end of the fixing belt is fixedly connected to the mud bucket, the other end of the fixing belt is connected to the fixing seat by a screw, and a hanging lug for the fixing belt to pass through is fixedly connected to the conformal ring.
[0010] The present invention is further configured such that: one end of the suction pipe is detachably connected to a guide sleeve, the diameter of the guide sleeve is larger the further away from the suction pipe, and when the conformal ring is fixed by the fixing band, the guide sleeve abuts against the outer edge of the lower fixing sleeve.
[0011] The present invention is further configured such that: a connecting sleeve is fixedly connected to the inner peripheral wall of the suction pipe, one side of the connecting sleeve is flush with one end of the suction pipe, an internal thread is provided on the inner peripheral wall of the connecting sleeve, and an external thread that mates with the internal thread is provided on the outer peripheral wall of the guide sleeve.
[0012] The present invention is further configured such that the fixing seat and the fixing belt are both located on the boundary line between the mud hopper and the inner wall of the pool.
[0013] In summary, this utility model has the following beneficial effects:
[0014] When maintaining the mud hopper, one end of the suction pipe is separated from the lower fixed sleeve, and the limiting position of the bent section of the suction pipe on the inner wall of the mud hopper is released. This allows the suction pipe, located below the upper fixed sleeve, to move freely. At this time, one can hold one end of the suction pipe and move the movable end to suck up the sludge from the inner wall of the mud hopper. After releasing the limiting position of the bent section of the suction pipe, the suction pipe has more movable length, making it easier for people to operate. The above settings eliminate the need to push the sludge to a specific position; one only needs to move the end of the suction pipe with the suction port, making operation more convenient.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0020] Wastewater treatment sedimentation tanks, such as Figure 1 and Figure 2 As shown, the system includes a pool body 1 and a sludge hopper 2 located at the bottom of the pool body 1. A suction pipe 3, with one end extending into the sludge hopper 2, is provided on the inner wall of the pool body 1. An upper fixing sleeve 4 is fixedly connected to the inner wall of the pool body 1, and a lower fixing sleeve 5 is fixedly connected to the inner circumferential wall of the sludge hopper 2. The upper fixing sleeve 4 and the lower fixing sleeve 5 are respectively fitted onto both ends of the suction pipe 3. Both the upper fixing sleeve 4 and the lower fixing sleeve 5 are rigid sleeves, while the suction pipe 3 is a flexible pipe. The upper fixing sleeve 4 and the lower fixing sleeve 5 can maintain the state of both ends of the suction pipe 3, making it difficult for the suction port of the suction pipe 3 to move during normal operation, thus ensuring the stability of the suction. The portion of the suction pipe 3 located between the upper fixing sleeve 4 and the lower fixing sleeve 5 is bent towards the inner wall of the sludge hopper 2 and fixed in place by the sludge. On the inner wall of the hopper 2, one end of the suction pipe 3 can be detached from the lower fixing sleeve 5. When people maintain the hopper 2, they separate one end of the suction pipe 3 from the lower fixing sleeve 5, and release the limit of the bent section of the suction pipe 3 from the inner wall of the hopper 2. This setting allows the suction pipe 3 located below the upper fixing sleeve 4 to move freely. At this time, people can hold one end of the suction pipe 3 by hand and suck up the sludge on the inner wall of the hopper 2 by moving the movable end of the suction pipe 3. After releasing the limit of the bent section of the suction pipe 3, the suction pipe 3 has more movable length, which is more convenient for people to operate. The above setting means that people no longer need to push the sludge to a specific position, but only need to move the end of the suction pipe 3 with the suction port, which is convenient for people to operate.
[0021] like Figure 2 and Figure 3 As shown, a conformal ring 6 is fixedly connected to the outer peripheral wall of the suction pipe 3. The inner diameter of the conformal ring 6 is equal to the outer diameter of the suction pipe 3. The bending of the suction pipe 3 is achieved by limiting and fixing the conformal ring 6 to the inner wall of the mud hopper 2. The conformal ring 6 is a rigid ring. Fixing the conformal ring 6 to the outer peripheral wall of the suction pipe 3 can limit the shape of this section of the suction pipe 3, making this section of the suction pipe 3 less prone to deformation. In addition, the conformal ring 6 can also facilitate the installation of a fixing structure, which facilitates the fixing of the suction pipe 3 to the inner wall of the mud hopper 2. A fixing band 7 and a fixing seat 8 are fixedly connected to the inner wall of the mud hopper 2. One end of the fixing band 7 is fixedly connected to the mud hopper 2, and the other end of the fixing band 7 is connected by a screw. The wire is connected to the fixing seat 8. The conformal ring 6 is fixedly connected to the lug 9 for the fixing strap 7 to pass through. The fixing strap 7 is made of plastic and has strong fixing strength. After passing one end of the fixing strap 7 through the lug 9 and fixing it to the fixing seat 8 with screws, the fixing strength of the fixing strap 7 can be guaranteed. The screw fixing method also facilitates subsequent disassembly. The fixing seat 8 and the fixing strap 7 are both located on the dividing line between the mud hopper 2 and the inner wall of the pool 1. Because the mud is easy to accumulate at the bottom of the mud hopper 2, the top of the mud hopper 2 is relatively less prone to stubborn dirt, which makes it easy to install and remove the fixing strap 7.
[0022] like Figure 2 and Figure 3 As shown, a guide sleeve 10 is detachably connected to one end of the suction pipe 3. The diameter of the guide sleeve 10 increases as it moves further away from the suction pipe 3. When the conformal ring 6 is fixed by the fixing band 7, the guide sleeve 10 abuts against the outer edge of the lower fixing sleeve 5, and the guide sleeve 10 acts as a flare, thus ensuring the suction efficiency of the suction pipe 3. Furthermore, by fixing the conformal ring 6 to the outer wall of the mud hopper 2, one end of the suction pipe 3 is pulled upward, causing the guide sleeve 10 to abut against the lower edge of the lower fixing sleeve 5, ensuring the stability of the suction port end of the suction pipe 3. A connecting sleeve is fixedly connected to the inner circumferential wall of the suction pipe 3. One side of the connecting sleeve is flush with one end of the suction pipe 3. The inner circumferential wall of the connecting sleeve is provided with an internal thread, and the outer circumferential wall of the guide sleeve 10 is provided with an external thread that mates with the internal thread. By threading one end of the guide sleeve 10 onto the connecting sleeve, the guide sleeve 10 can be fixed, and it is also convenient to disassemble the guide sleeve 10 later.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
