Abstract
Description
Technical Field
[0001] The utility model relates to the field of sewage treatment, and more specifically, to a horizontal flow sedimentation tank. Background Technique
[0002] A horizontal flow sedimentation tank is a common sewage treatment device, mainly used for separating suspended substances and organic substances in sewage. Its working principle is based on the natural action of water flow and the principle of sediment gravity settlement. By slowing down the water flow speed, the suspended particles in the sewage gradually settle, achieving the purification effect.
[0003] The sedimentation tank includes a tank body. An inlet and an outlet are respectively arranged on both sides of the tank body. Sewage enters the tank body through the inlet, flows in the tank body for a period of time, and then flows out from the outlet. During the flow of the sewage, the particulate matter in the sewage will settle at the bottom of the tank. In order to prevent excessive accumulation of particulate matter at the bottom of the tank body, a sludge hopper is currently arranged on the bottom surface of the tank body, and a sludge scraping chain is arranged in the tank body. The particulate matter at the bottom of the tank is scraped into the sludge hopper by the sludge scraping chain. A sewage suction pipe is arranged in the sludge hopper, and the sewage suction pipe sucks out the particulate matter in the sludge hopper.
[0004] The sewage suction pipe cannot pump out all the particulate matter in the sludge hopper because some particulate matter is easily compacted during the sedimentation process, resulting in adhesion to the inner wall of the sludge hopper. Therefore, this part of the particulate matter needs to be manually removed. However, the existing sewage suction pipe is fixed in the tank body, and the sewage suction pipe is relatively close to the bottom surface of the sludge hopper, which has a certain interference to the process of people cleaning the inner wall of the sludge hopper.
[0005] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model
[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a horizontal flow sedimentation tank.
[0007] The above technical purpose of the utility model is achieved through the following technical solution: A horizontal flow sedimentation tank includes a tank body and a sludge hopper arranged on the bottom surface of the tank body. A sewage suction pipe with one end extending into the sludge hopper is arranged in the tank body. The pipe body of the sewage suction pipe is flexible. A rigid sleeve sleeved on the sewage suction pipe is fixedly connected to the side wall of the tank body. The length of the rigid sleeve along the depth direction of the sludge hopper is adjustable. When the length of the rigid sleeve along the depth direction of the sludge hopper reaches the minimum state, one end of the sewage suction pipe can be bent and fixed on the outer wall of the rigid sleeve.
[0008] The utility model is further arranged as follows: The rigid sleeve includes a fixed sleeve and a sliding sleeve. A plurality of sliding grooves are opened on the outer wall of the fixed sleeve. A sliding block located in the sliding groove is fixedly connected to the inner wall of the sliding sleeve. A limiting rod for restricting the sliding of the sliding sleeve on the fixed sleeve is arranged on the sliding sleeve.
[0009] The utility model is further configured that: a sliding hole penetrating the thickness direction is formed in the sliding sleeve, the limiting rod is slidably connected in the sliding hole, and a limiting hole for inserting the limiting rod is formed in the outer wall of the fixed sleeve.
[0010] The utility model is further configured that: the limiting rod can rotate in the sliding hole, internal threads are formed in the inner wall of the limiting hole, and external threads for cooperating with the internal threads are arranged at one end of the limiting rod.
[0011] The utility model is further configured that: a shape-retaining ring for maintaining the shape of the pipe orifice is fixedly connected to the inner wall of the sewage suction pipe, a flaring member is fixedly connected to the sewage suction pipe, and the flaring member can support the gap between the sewage suction pipe and the sliding sleeve.
[0012] The utility model is further configured that: one end of the limiting rod is always exposed outside the sliding sleeve, and a collar for sleeving on the limiting rod is fixedly connected to the flaring member.
[0013] The utility model is further configured that: a plurality of annular grooves for embedding the collar are formed in the outer peripheral wall of the limiting rod.
[0014] In summary, the utility model has the following beneficial effects: when it is necessary to manually clean the inner wall of the mud bucket, people adjust the length of the rigid sleeve and make its length in the direction of the mud bucket reach the minimum. At this time, the pipe body near the pipe orifice of the sewage suction pipe is exposed outside the rigid sleeve. At this time, people can bend this part of the pipe body and fix it on the rigid sleeve. Such a setting makes the overall distance between the sewage suction pipe and the inner wall of the mud bucket far, reduces the interference of the sewage suction pipe on the cleaning process, and makes it more convenient for people to clean the inner wall of the mud bucket.

[0021] The following combines the drawings and embodiments to describe the present utility model in detail.
[0022] Horizontal flow sedimentation tank, as Figure 1 and Figure 3 shown, includes a pool body 1 and a mud hopper 2 arranged at the bottom of the pool body 1. A sewage suction pipe 3 with one end extending into the mud hopper 2 is arranged in the pool body 1. The pipe body of the sewage suction pipe 3 is flexible. A rigid sleeve sleeved on the sewage suction pipe 3 is fixedly connected to the side wall of the pool body 1. The rigid sleeve is used to maintain the shape of the pipe body of the sewage suction pipe 3. The length of the rigid sleeve along the depth direction of the mud hopper 2 is adjustable. When the length of the rigid sleeve along the depth direction of the mud hopper 2 reaches the minimum state, one end of the sewage suction pipe 3 can be bent and fixed on the outer wall of the rigid sleeve. During the filtration process of the pool body 1, the rigid sleeve is sleeved on the pipe body of the sewage suction pipe 3, which can maintain the overall shape of the pipe body, so that the flexible pipe body is not easily bent too much under the impact of water flow, thus ensuring the sewage suction effect of the sewage suction pipe 3. When it is necessary to manually clean the inner wall of the mud hopper 2, people adjust the length of the rigid sleeve and make its length along the direction of the mud hopper 2 reach the minimum. At this time, the pipe body near the pipe orifice of the sewage suction pipe 3 is exposed outside the rigid sleeve. At this time, people can bend this part of the pipe body and fix it on the rigid sleeve. Such a setting makes the overall distance between the sewage suction pipe 3 and the inner wall of the mud hopper 2 farther, reducing the interference of the sewage suction pipe 3 on the cleaning process and making it more convenient for people to clean the inner wall of the mud hopper 2.
[0023] As Figure 5 shown, the rigid sleeve includes a fixed sleeve 4 and a sliding sleeve 5. The sliding sleeve 5 is located below the fixed sleeve 4. A plurality of sliding grooves 6 are opened on the outer wall of the fixed sleeve 4. A sliding block 7 located in the sliding groove 6 is fixedly connected to the inner wall of the sliding sleeve 5. People slide the sliding sleeve 5 upward to reduce the length of the rigid sleeve along the depth direction of the mud hopper 2. A limiting rod 8 for restricting the sliding of the sliding sleeve 5 on the fixed sleeve 4 is arranged on the sliding sleeve 5. By controlling the limiting rod 8, the limiting rod 8 can restrict the sliding of the sliding sleeve 5. Furthermore, when the sliding sleeve 5 slides upward to the limiting position, the limiting rod 8 can restrict the sliding of the sliding sleeve 5 to ensure the stability of the sliding sleeve 5.
[0024] As Figure 3 and Figure 4As shown in the figure, a sliding hole 9 penetrating through the thickness direction is formed in the sliding sleeve 5, and the limiting rod 8 is slidably connected in the sliding hole 9. A limiting hole 10 for inserting the limiting rod 8 is formed in the outer wall of the fixed sleeve 4. When the sliding sleeve 5 slides upward to the limiting position, one end of the sliding rod is aligned with the limiting hole 10. After people slide the sliding sleeve 5 upward to the limiting position, people directly insert the limiting rod 8 into the limiting hole 10. Such a setting realizes the limiting effect of the limiting rod 8 on the sliding sleeve 5. The limiting rod 8 can rotate in the sliding hole 9. Internal threads are formed on the inner wall of the limiting hole 10, and external threads for cooperating with the internal threads are provided at one end of the limiting rod 8. By rotating the limiting rod 8, the limiting rod 8 can enter the limiting hole 10. Through the cooperation of the external threads and the internal threads, the limiting rod 8 is not easily separated from the limiting hole 10, thereby ensuring the cooperation strength between the limiting rod 8 and the limiting hole 10.
[0025] As Figure 1 and Figure 2 shown in the figure, a shape-retaining ring 11 for maintaining the shape of its pipe orifice is fixedly connected to the inner wall of the sewage suction pipe 3. An flaring member 12 is fixedly connected to the outer peripheral wall of the sewage suction pipe 3. The flaring member 12 can support the gap between the sewage suction pipe 3 and the sliding sleeve 5. The flaring member 12 includes a support ring at its upper end. When the sliding sleeve 5 slides downward to the limiting position, the support ring is located between the shape-retaining ring and the sliding sleeve 5. Since the outer diameter of the sliding sleeve 5 is larger than the outer diameter of the fixed sleeve 4, there will be a certain gap between the inner diameter of the sliding sleeve 5 and the inner wall of the sewage suction pipe 3. The shape-retaining ring 11 can support the shape of the orifice of the sewage suction pipe 3, and the flaring member 12 can support the gap between the orifice of the sewage suction pipe 3 and the sliding sleeve 5, so that the sewage suction pipe 3 is not easily shaken in the sliding sleeve 5. At the same time, the flaring member 12 can expand the sewage suction area of the orifice of the sewage suction pipe 3 and increase the sewage suction efficiency of the sewage suction pipe 3. One end of the limiting rod 8 is always exposed outside the sliding sleeve 5. The length of the limiting rod 8 is greater than the sum of the depths of the limiting hole 10 and the round hole. A collar 13 for sleeving on the limiting rod 8 is fixedly connected to the flaring member 12. After the sliding sleeve 5 slides upward to the limiting position, people directly sleeve the collar 13 on the limiting rod 8. The collar 13 can drive one end of the sewage suction pipe 3 to bend, so as to realize bending and fixing one end of the sewage suction pipe 3 on the rigid sleeve. A plurality of annular grooves 14 for embedding the collar 13 are formed on the outer peripheral wall of the limiting rod 8. The arrangement of the annular grooves 14 limits the collar 13 in the annular grooves 14, so that the collar 13 is not easily separated from the limiting rod 8.

All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as the protection scope of the present invention.
