Description

Technical Field

[0001] The utility model relates to the technical field of mud discharge, in particular to an automatic mud discharge device for a flocculation sedimentation tank in a water purification plant. Background Art

[0002] A water purification plant is an enterprise that purifies drinking water. Its role is to ensure that people can drink the water safely. A water purification plant has the function of preventing infectious diseases by providing clean water and maintaining public health. Its scale varies according to the conditions of the water source and the required water quality safety standards. A flocculation tank is required in the water purification process. A flocculation tank refers to a water purification tank that completes the flocculation process. It creates suitable hydraulic conditions to allow particles with flocculation properties to aggregate in mutual contact to form larger flocs. It plays an important role in water purification.

[0003] For example, Chinese patent (CN219546785U) discloses an automatic mud discharge device for a flocculation sedimentation tank in a water purification plant, comprising: a sedimentation tank, a top cover movably connected to the top of the sedimentation tank, a stepper motor is arranged at the top of the top cover, a fixed shaft is fixedly connected to the bottom of the stepper motor, a telescopic shaft is movably connected to the bottom of the fixed shaft, a spring column is fixedly connected to the outer surface of the bottom of the telescopic shaft, a spring is arranged inside the spring column, a limiting column is arranged inside the spring column, and a scraper is fixedly connected to one end of the limiting column; the utility model improves the automatic mud discharge device for a flocculation sedimentation tank in a water purification plant, and the telescopic shaft at the bottom and the scraper at the bottom of the telescopic shaft can be moved up and down by a stepper motor, so as to clean the sludge remaining on the inner wall of the flocculation sedimentation tank, and under the action of the spring inside the spring column, the scraper can also enter the funnel bin to clean the sludge at the bottom, which has the advantage of comprehensive cleaning, thereby effectively solving the problems and shortcomings of the existing device.

[0004] The above scheme also has the following technical deficiencies: the above scheme is inconvenient for flushing the side walls and inclined walls of the tank body; since there is a lot of residual sludge inside the tank body, simply using a scraper to scrape off the sludge will inevitably cause sludge to remain inside the tank body, resulting in poor cleaning effect; at the same time, due to the limited compression degree of the spring and the small scraping area on the bottom side of the scraper, it is difficult for the scraper to scrape off the sludge near the central axis of the funnel bin. Based on this, an automatic sludge discharge device for a flocculation sedimentation tank in a water treatment plant is proposed. Utility Model Content
