Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater treatment technology, and more specifically, to an industrial wastewater settling device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Industrial wastewater contains a lot of solid impurities. During the wastewater treatment process, the wastewater needs to be settled so that the solid particles inside settle to the bottom of the settling chamber, thereby separating the wastewater from the solid particles inside.

[0003] A search revealed that utility model patent CN215798935U discloses a sedimentation device for industrial wastewater treatment, comprising a sedimentation structure including a sedimentation tank, a cover opening, a sedimentation hopper, a sedimentation outlet, a water outlet, and a filter screen. A feed cover is installed on the upper side of the sedimentation structure, comprising a sealing cover body, a cover groove, a shim block, a motor lifting groove, a telescopic rod, a water inlet pipe, and a coagulant addition pipe. A stirring structure is installed on the bottom side of the feed cover, comprising a stirring shaft, a bidirectional motor, a stirring rod, a one-way bearing, a conical screw, a closed plug, and a drain screw. A cover opening is provided on the upper edge of the sedimentation tank. A sedimentation hopper is fixedly installed on the bottom side of the sedimentation tank, and a sedimentation outlet is fixedly installed on the bottom side of the sedimentation hopper. A water outlet is installed on one side of the sedimentation hopper. This sedimentation device for industrial wastewater treatment can quickly perform sedimentation and facilitate the discharge of sediment, greatly improving work efficiency and saving time and labor. However, the aforementioned patents have the following shortcomings: the outlet height is fixed, which can affect wastewater discharge when sludge clogs the outlet; furthermore, it is inconvenient to automatically add flocculants when continuously treating wastewater through sedimentation. Therefore, we propose an industrial wastewater sedimentation device. Utility Model Content

The output shaft of the first motor extends into the inner cavity of the settling tank and is fixedly connected to an agitator. The bottom end of the agitator extends into the inner cavity of the sludge discharge pipe and is fixedly connected to a sludge guiding spiral blade. The side of the sludge guiding spiral blade is in contact with the inner wall of the sludge discharge pipe. A scraper is fixedly connected to the side of the agitator. The side of the scraper is in contact with the inner wall at the bottom end of the inner cavity of the settling tank. Multiple agitator plates are fixedly connected to the side of the agitator and located in the inner cavity of the settling tank.

[0011] Compared with the prior art, the advantages of this utility model are as follows: In this utility model, after the sewage settles in the inner cavity of the settling tank, the height of the lifting sealing plate and the electrically controlled drain valve is adjusted by the electric push rod so that the bottom of one end of the electrically controlled drain valve is flush with the sewage and sludge separation layer, so as to open the electrically controlled drain valve to discharge the settled sewage and avoid the settled sludge from clogging the electrically controlled drain valve and affecting the discharge of sewage.

[0012] In this invention, after the wastewater is introduced into the inner cavity of the settling tank, the flocculant is stored in the storage cylinder and its own weight is used to make it enter the conveying pipe. The second motor drives the spiral conveying rod to rotate and drive the flocculant to move in the conveying pipe, so that the flocculant is automatically added into the inner cavity of the settling tank. This allows the flocculant to be automatically added to the wastewater during multiple wastewater settling treatments, making it highly practical. Attached Figure Description
