Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment sludge discharge, in particular to a separated high-density sedimentation tank sludge discharge device. Background Art

[0002] In modern sewage treatment processes, sedimentation tanks play a vital role. They separate solid particles from liquid in sewage through the principle of gravity sedimentation, thereby achieving initial sewage purification. However, with the continuous increase in sewage treatment volume and the increasing requirements for treatment efficiency and quality, traditional sedimentation tank sludge discharge devices have exposed many shortcomings.

[0003] The sludge discharge method of traditional sedimentation tanks is often relatively simple, relying solely on the gravity of the sludge itself to discharge the sludge through the sludge discharge pipe at the bottom. This method is prone to poor sludge discharge when the sludge concentration is high or the sludge viscosity is large, causing sludge to accumulate at the bottom of the sedimentation tank, reducing the effective volume of the sedimentation tank, and thus affecting the treatment capacity of the entire sewage treatment system. Moreover, gravity sludge discharge cannot effectively clean the sludge attached to the inner wall of the sedimentation tank. After long-term operation, the sludge layer on the inner wall will gradually thicken, which not only reduces the hydraulic efficiency of the sedimentation tank, but also prevents the impurities in the sewage from being fully precipitated and separated, thereby reducing the effluent water quality.

[0004] The degree of automation of traditional mud discharge devices is generally low, and most of them require regular manual inspections and manual operations to control the mud discharge process. This not only consumes a lot of manpower and time costs, but also because it is difficult to accurately grasp the timing and amount of mud discharge during manual operation, it is easy to cause excessive or insufficient mud discharge. Summary of the invention

[0030] Specifically, the linear motion part includes a limit groove 18, a movable groove 17, and a chain guide frame 22. The limit groove 18 is opened on one side of the mounting frame 14, and the movable groove 17 is opened on the other side of the mounting frame 14. The movable groove 17 and the limit groove 18 are vertically arranged, and two sets of chain guide frames 22 are symmetrically arranged on the inner wall of the mounting frame 14.

[0031] In this embodiment, the mounting frame 14 is used to mount the linear motion part. The limiting groove 18 opened on one side of the mounting frame 14 is arranged parallel to the inner wall of the mounting groove 13. The movable notch 17 is parallel to the guide block 16 arranged on the guide frame 19.

When the guide block 16 squeezes the rigid chain 23, the rigid chain 23 moves linearly along the inner side of the chain guide frame 22, wherein the chain guide frame 22 is provided in an "L" shape, thereby realizing the conversion of the vertical movement of the rigid chain 23 into horizontal movement. The connecting seat 24 at one end of the rigid chain 23 drives the second scraper blade 12, so that the second scraper blade 12 scrapes the sludge on the surface of the inclined surface 9.
