Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a pipe fitting for sewage treatment. Background Art

[0002] Sewage refers to the polluted water discharged from life and production. After long-term use, the inner wall of the sewage pipe will be attached with silt and other impurities. If it is not cleaned in time, the silt on the inner wall of the sewage pipe will increase, which will block the sewage pipe and affect the normal discharge of sewage. At the same time, silt and other impurities accumulate on the wall of the sewage pipe for a long time, which will slowly corrode the wall and affect the service life of the sewage pipe.

[0003] Patent CN2020207925080 discloses a pipe fitting for sewage treatment, including a pipe body, a joint is provided at one end of the pipe body, a mounting rod is axially provided in the pipe body, a scraper is provided on the outer wall of the mounting rod to abut against the inner wall of the pipe body, a mounting frame is provided in the joint, the end of the mounting rod close to the joint extends outward and is rotatably connected to the mounting frame, a fixing frame is provided on the inner side wall of the pipe body away from the end of the joint, the end of the mounting rod away from the mounting frame is rotatably connected to the fixing frame, and a driving component for driving the mounting rod to rotate circumferentially is provided at the end of the mounting rod close to the joint. The scraper is arranged in a spiral shape, and a drainage hole is provided through the plate body. This technology drives the mounting rod and the scraper to rotate synchronously through the driving component, so that the scraper scrapes the inner wall of the pipe body to prevent impurities such as silt from adhering to the inner wall of the pipe body, thereby realizing the cleaning function of the inner wall of the pipe body. However, in actual use, the spiral scraper will hinder the flow of sewage, and there are many impurities in the sewage. After a period of use, the drainage holes on the scraper will be blocked, further reducing the sewage flow rate, so that the bottom driving mechanism cannot obtain sufficient impact force and cannot drive the scraper to rotate, which will eventually cause the sewage pipe to be blocked.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, the meanings of "several" and "a number of" are two or more, unless otherwise clearly and specifically defined.

[0022] Referring to the drawings. The pipe fitting for sewage treatment described in this embodiment includes a pipe fitting body 1 and a cleaning component 2 inside the pipe fitting body 1. The top of the tubular body 1 is provided with a first interface 11, the first interface 11 is an internal thread interface, and a first step surface 12 is provided inside the first interface; the bottom of the tubular body 1 is provided with a second interface 13, the second interface 13 is an external thread interface, and a second step surface 14 is provided inside the second interface; an anti-corrosion layer 15 is provided on the inner wall of the pipe body 1, and the anti-corrosion layer 15 is made of ABS material or fiberglass material, which can improve the corrosion resistance of the pipe body and extend the service life of the pipe.

[0023] The cleaning component 2 includes a first mounting bracket 21, a second mounting bracket 22, a rotating shaft 23, a scraping strip 24 and an impeller 25. The first mounting bracket 21 is stuck on the first step surface 12 and fixedly connected to the first step surface 12. Here, it can be fixedly connected to the first step surface through components such as screws. Or it can be positioned with a positioning pin relative to the first step surface to restrict the rotation of the first mounting bracket. The components connected to the first interface subsequently will press against the first mounting bracket to prevent the first mounting bracket from disengaging from the interface. The second mounting bracket 22 is stuck on the second step surface 14 and can be fixedly connected to the second step surface through components such as screws. A sloping plate 26 is provided below the second mounting bracket 22. The sloping plate slopes downward and can converge the water flow towards the impeller 25 to increase the water flow impact force.

[0024] Both the first mounting bracket 21 and the second mounting bracket 22 are made of a hollow material and include a circular ring 27, mounting columns 28 and connecting rods 29. The mounting columns 28 are installed at the center of the circular ring 27 through the connecting rods 29. Both ends of the rotating shaft 23 pass through the mounting columns 28 and are rotationally matched with the mounting columns through bearings.

[0025] A spiral scraping strip 24 is provided on the periphery of the rotating shaft 23. The scraping strip 24 is connected to the rotating shaft 23 through multiple sections of support rods 210; the scraping strip 24 is connected to the rotating shaft 23 through the support rods 210. The spacing between adjacent support rods 210 is large and will not hinder the flow of sewage. The rotating shaft 23, the first mounting bracket 21, the second mounting bracket 22, the support rods 210 and the scraping strip 24 are all made of ABS material, which has good corrosion resistance and can extend the service life.

[0026] An impeller 25 is fixedly installed at one end of the rotating shaft 23 facing the bottom of the tubular body. Under the impact force of the water flow, the impeller 25 will rotate, thereby driving the rotating shaft 23 to rotate. The rotating shaft can drive the scraping strip 24 to rotate, and finally the scraping strip 24 scrapes off the silt adhering to the inner wall of the tubular body 1, preventing the inside of the pipeline body from being blocked and extending the service life of the sewage pipe fittings.
