Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation tanks, in particular to a high-efficiency inclined-plate sedimentation tank for sewage. Background Technique

[0002] The sedimentation tank is a link for solid-liquid separation in the drainage treatment system. The sedimentation process in water treatment refers to the process of separating suspended solids from water under the action of gravity. After the raw water undergoes the processes of chemical dosing, mixing, and reaction, the form of suspended solids in the water changes into larger flocculants, which need to be separated in the sedimentation tank to complete the clarification function. The turbidity of the water after coagulation and sedimentation is generally below a certain degree. The traditional inclined-plate sedimentation tank is developed based on the shallow tank theory and is a sedimentation tank with many parallel inclined thin plates with small spacing installed inside. Due to the installation of the inclined plates, the hydraulic radius of the sedimentation tank decreases, meeting the requirements of water flow stability and laminar flow stability, thereby improving the sedimentation effect.

[0003] For example, the existing Chinese invention patent with the application number CN202222432443.0 discloses a high-efficiency inclined-plate sedimentation tank for sewage. The utility model relates to the technical field of sewage treatment. The high-efficiency inclined-plate sedimentation tank for sewage includes a main body of the inclined-plate sedimentation tank, and a sewage collection chamber is fixedly connected to the bottom of the main body of the inclined-plate sedimentation tank. By installing a driving motor, a rotating rod, and a stirring rod, etc., when the driving motor drives the rotating rod to rotate, the surface of the scraping plate will slide inside the sewage collection chamber to scrape the sludge on the inner wall of the sewage collection chamber. At the same time, when the first connecting rod and the stirring rod rotate, they can stir the sludge inside the sewage collection chamber to facilitate the dilution of the sludge, enhancing the efficiency. By setting a sliding groove, a sliding block, and an elastic block, due to the elasticity of the elastic block, the sliding block can slide towards the inner wall of the sewage collection chamber, enabling the first connecting rod and the second connecting rod to drive the scraping plate to tightly abut and connect inside the sewage collection chamber, so as to thoroughly clean the sludge on the inner wall of the sewage collection chamber and enhance the practicability.

[0004] The existing inclined-plate sedimentation tanks are small in volume, resulting in the ability to treat only a small part of the sewage. When a large amount of sewage needs to be treated, it needs to be treated multiple times, which is very inconvenient to use. Content of the Utility Model
