Description

Technical Field

[0001] The utility model relates to the technical field of industrial wastewater treatment, in particular to industrial wastewater precipitation equipment. Background Art

[0002] Industrial wastewater refers to wastewater and waste liquid discharged during the production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with the water. It is an important cause of environmental pollution, especially water pollution. Industrial wastewater contains a large amount of impurities and suspended matter. Due to the large number of pollutants in industrial wastewater, in order to avoid environmental pollution when the wastewater is discharged, sedimentation treatment is required before discharge.

[0003] The Chinese utility model patent announcement number CN215505924U discloses an industrial wastewater sedimentation tank that can be desilted, including a box body, a drawer is movably connected to the upper end of the inner cavity of the box body, a filter screen is arranged at the bottom of the inner cavity of the drawer, a protection box is fixedly connected to the right side of the inner cavity of the box body, and a motor is fixedly connected to the inner cavity of the protection box through a support frame. When sludge is accumulated at the bottom of the inner cavity of the box body, the output shaft of the motor drives the threaded rod to rotate, and the threaded rod drives the threaded sleeve to move to the right while rotating, and the threaded sleeve drives the connecting rod to move to the right, and the scraper and the brush rod are driven to move to the right through the connecting rod, and the valve is opened at the same time, and then the sludge is driven to move to the right while the scraper and the brush rod move to the right, and finally the sludge at the bottom of the inner cavity of the box body is discharged through the sludge discharge pipe, so as to clean the sludge. However, in the above-mentioned sedimentation tank, the wastewater is only filtered through the filter screen when it is precipitated, and the filtering function is relatively simple. Impurities may still exist in the water body when the wastewater is discharged, thereby reducing the filtering effect of the sedimentation tank on the wastewater. Utility Model Content

[0039] Working principle: When in use, the wastewater is injected into the sedimentation tank 1 through the water inlet pipe 2. The wastewater will slowly rise with the injection liquid level, and slowly rise upward through the coarse filter screen 4.

At this time, the baffle 7 is pulled outward, and the baffle 7 drives the positioning block 8 to move outward to facilitate opening the sewage outlet 5. Then the servo motor 601 is started. When the servo motor 601 works, it drives the screw rod 602 to rotate. Under the sliding cooperation of the limit rod 2001 and the limit sleeve 2002, the screw rod 602 rotates to drive the nut 604 to move.
