Description

Technical Field

[0001] The utility model relates to the technical field of industrial sewage treatment, in particular to industrial sewage purification equipment for environmental protection projects. Background Art

[0002] Environmental protection projects refer to projects specifically designed for environmental protection. Due to industrial development leading to environmental pollution, environmental pollution problems are solved through the organized activities of a group of people based on a set of envisioned goals and the application of relevant scientific knowledge and technical means.

[0003] 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 during the production process that are lost with the water. Since the wastewater contains solid impurities such as heavy metals and toxic substances, it needs to be treated by a purification device and meet the standards before proceeding to subsequent steps. In the process of wastewater treatment, a flocculant adder is often required to allow the flocculant to fully combine with the debris in the wastewater to form flocs. The existing flocculants are added manually during the addition process and cannot be added automatically and quantitatively. The amount of flocculant added is difficult to control. Excessive addition of flocculants will result in excessive flocculation, which is not convenient for the subsequent treatment of wastewater. Adding too little flocculant will result in poor flocculation effect, which is not convenient for wastewater treatment operations. Utility Model Content

During the rotation of the elliptical block 37, the moving plate 35 is pressed against the side of the elliptical block 37 by the elastic force of the spring 314. When the elliptical block 37 rotates, it intermittently pushes the moving plate 35 to move, and drives the baffle 36 through the connecting rod 313, so that the square groove on the baffle 36 coincides with the discharge port of the flocculant adding box 34, thereby enabling the flocculant adding box 34 to be rotated.
