Description

Technical Field

[0001] The utility model relates to a multi-effect sedimentation tank with a self-cleaning function, belonging to the technical field of sewage treatment equipment. Background Art

[0002] At present, most of the sewage treatment processes at home and abroad adopt the forms of sedimentation, filtration and disinfection. Among them, the removal of suspended solids in the raw water in the sedimentation part is particularly important. As one of the main facilities for removing suspended solids in water, sedimentation tanks have been widely used in the sewage treatment industry. The tank types of sedimentation tanks mainly include horizontal flow sedimentation tanks and inclined tube sedimentation tanks.

[0003] In inclined tube sedimentation, a large number of inclined tube components at a certain angle to the horizontal plane are placed in the sedimentation tank. The water flow can flow from bottom to top or from top to bottom, and the particles sink to the bottom and then slide down automatically. Analyzing from the aspect of improving the hydraulic conditions of the sedimentation tank, since the hydraulic radius of the sedimentation tank is greatly reduced, the Reynolds number R is greatly reduced and the Froude number is greatly increased, meeting the requirements of water flow stability and laminar flow, and significantly improving the sedimentation efficiency. Therefore, inclined tube sedimentation tanks are more and more widely used.

[0004] After the inclined tube components are used for a period of time, sediments, water scales, etc. will adhere to the surface and inside of the inclined tubes, and need to be cleaned regularly to maintain the equipment performance and extend the service life. At present, the cleaning of inclined tubes is generally manual cleaning. Workers hold cleaning devices or high-pressure water guns to clean. Since the inclined tubes are arranged at a certain angle to the horizontal plane, there are easy to be cleaning dead corners in the manual cleaning process, and the sediments and water scales inside the inclined tubes are not easy to be completely removed, and the cleaning process is time-consuming and laborious.

[0005] To sum up, it is obvious that there are inconveniences and defects in the prior art in actual use, so it is necessary to improve. Content of the Utility Model

Above one side of the primary sedimentation chamber 6 close to the secondary sedimentation chamber 7, there is an overflow weir 13, and the sewage treated by sedimentation in the primary sedimentation chamber 6 enters the secondary sedimentation chamber 7 from the overflow weir 13.

[0036] An inclined tube assembly 12 is installed in the middle of the inner cavity of the primary sedimentation chamber 6, and a self-cleaning assembly 14 is fixedly installed above the inclined tube assembly 12, and the self-cleaning assembly 14 realizes effective cleaning treatment of the inclined tube assembly 12.

[0037] The self-cleaning assembly 14 includes a support frame 149, the support frame 149 is fixedly connected to the top of the primary sedimentation chamber 6, a rotary seat 145 is arranged at the bottom of the support frame 149, the rotary seat 145 is connected to the support frame 149 through a slewing bearing 148, and a motor 147 for driving the rotary seat 145 to perform a rotary motion is arranged above the support frame 149.

[0038] A support arm 144 is fixedly connected to the side of the rotary seat 145, and one end of the support arm 144 away from the rotary seat 145 is hinged to a swing seat 143, and the swing seat 143 rotates along with the rotary seat 145.
