In the wastewater treatment system, the stability, sealing and reliability of pipeline connection are key factors to ensure wastewater treatment efficiency and prevent secondary pollution. Traditional pipeline connection methods, such as welding and flange connection, have some shortcomings.
[0003] Welded connections are difficult to construct and are hard to repair once damaged. Flange connections require a large number of bolts and gaskets, resulting in high installation and maintenance costs. When a pipeline malfunctions or needs to be replaced, traditional connection methods require the removal of a large number of bolts, which limits the operating space and makes the disassembly and installation process very inconvenient, increasing the difficulty and time cost of maintenance work.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example
[0030] Please see Figure 1-6In this embodiment of the present invention, a pipe connection mechanism for sewage treatment includes two annular sleeves 100, two clamping units 300, two sealing rings 400, and an elastic tube 200. Both annular sleeves 100 are hollow structures, and annular air bladders 110 are provided on the inner walls of both annular sleeves 100. The annular sleeves 100 are made of high-strength, corrosion-resistant plastic or metal materials. The annular air bladders 110 are tightly fitted to the inner walls of the annular sleeves 100 and have good elasticity. The inner surface of the annular air bladders 110 is provided with anti-slip textures, which can increase the friction between the annular air bladders 110 and the outer wall of the sewage pipe, preventing the annular air bladders 110 from sliding and further improving the stability of the connection. The outer wall of the annular sleeves 100 is provided with a one-way air inlet valve 120 and an exhaust port 130 communicating with the annular air bladders 110. The elastic tube 200 is connected between the two annular sleeves 100 to accommodate... With varying spacing and angles between sewage pipes, two clamping units 300 are located on opposite sides of the two annular sleeves 100. Each clamping unit 300 includes an outer shell 310 with a circular groove 311 extending through its side wall. A sealing ring 400 is inserted into the circular groove 311. Inside the outer shell 310, two bidirectional screw rods 320 are installed, one horizontally and the other vertically. The outer walls of both bidirectional screw rods 320 are screwed with two connecting rods 330. Arc-shaped clamps 340 are fixedly connected to the opposite bottom sides of the two connecting rods 330. The outer wall of the outer shell 310 has two knobs 350 connected to the ends of the two bidirectional screw rods 320. The two ends of the sealing ring 400 are connected to the annular sleeve 100 and the outer wall of the outer shell 310, respectively. The interior of the sealing ring 400 is used for inserting sewage pipes.
[0031] Specifically, during installation, firstly, insert the ends of the two sewage pipe sections into the circular grooves 311 of the two outer casings 310, extending their ends into the annular sleeve 100. The inner wall of the sealing ring 400 also contacts the outer wall of the sewage pipe. Rotate the knob 350 connected to the horizontally arranged bidirectional screw 320, bringing the two connecting rods 330 on the outer wall of the bidirectional screw 320 closer together. This causes the corresponding two arc-shaped clamps 340 to apply pressure to the left and right sides of the sealing ring 400 for clamping. Then, rotate the knob 350 connected to the longitudinally arranged bidirectional screw 320, bringing the two connecting rods 330 on the outer wall of the bidirectional screw 320 closer together, thus clamping the sealing ring 400. The two arc-shaped clamps 340 apply pressure to the upper and lower sides of the sealing ring 400 to clamp it, so that the sealing ring 400 is tightly attached to the outer wall of the sewage pipe, thereby achieving a preliminary seal. Then, the one-way air inlet valve 120 inflates the annular air bag 110. After the annular air bag 110 is inflated, its inner ring will expand and tightly adhere to the outer wall of the sewage pipe, further enhancing the sealing performance. When it is necessary to disassemble the pipe, first open the exhaust port 130 to release the gas in the annular air bag 110, causing the annular air bag 110 to contract. Then, rotate the two knobs 350 in the opposite direction so that the arc-shaped clamps 340 no longer clamp the sealing ring 400, and the connection mechanism can be removed to separate the two sections of sewage pipe.
[0032] like Figure 6 As shown, in this embodiment, annular grooves 410 are provided on the outer walls at both ends of the sealing ring 400. Fixing plates 420 are fitted into the two annular grooves 410. The two fixing plates 420 are detachably fixed to the side walls of the outer shell 310 and the annular sleeve 100, respectively. The sealing ring 400 is made of highly elastic and corrosion-resistant rubber material to adapt to minor deformations at the pipe connection and prevent sewage leakage.
[0033] In this embodiment, both the outer walls of the annular sleeve 100 and the outer shell 310 are provided with mounting holes. The fixing plate 420 is detachably fixed to the annular sleeve 100 or the outer shell 310 by bolts, which facilitates quick replacement of the sealing ring 400 or other components when needed, reducing maintenance costs and time.
[0034] like Figure 2-3 As shown, in this embodiment, the elastic tube 200 includes two connecting tubes 210, and a corrugated tube 220 is connected between the two connecting tubes 210. The other ends of the two connecting tubes 210 are respectively fixedly connected to the side walls of the two annular sleeves 100. The corrugated tube 220 is made of corrosion-resistant stainless steel or plastic, which can adapt to the corrosive media in the sewage treatment environment, and at the same time has good flexibility and pressure resistance.
[0035] In practice, the connecting pipe 210 and the annular sleeve 100 are connected by welding, gluing or clamping, and the connection is firm and well sealed. The two connecting pipes 210 are connected by a corrugated pipe 220. The corrugated pipe 220 has good flexibility and pressure resistance, and can adapt to small displacements at the pipe connection to ensure the stability of the connection.
[0036] like Figure 5 As shown, in this embodiment, the inner wall of the outer shell 310 and the top of the connecting rod 330 are provided with sliding grooves 312, and the top of the connecting rod 330 is slidably connected to the corresponding sliding grooves 312.
[0037] In practice, the top end of the connecting rod 330 is confined within the slide groove 312, so that when the bidirectional lead screw 320 rotates, the connecting rod 330 can move smoothly along the slide groove 312, thereby improving the stability of the structure.
[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
