AI Technical Summary

Technical Problem

During the use of thickeners, the separated acidic water is corrosive and contains solid particles, leading to direct discharge, which wastes water resources and affects the equipment. Existing technologies are difficult to effectively neutralize and filter for reuse.

Method used

By adding substances such as lime into the treatment tank to neutralize the acid water, and using the rotation of the stirring rod and the feeding pipe to achieve uniform mixing, combined with the filtration of the screen and the squeezing motion of the extrusion plate, the acid water can be filtered multiple times, neutralized and reused.

Benefits of technology

It achieves effective neutralization and filtration of acidic water, avoids corrosion of thickening equipment, reduces the impact of solid particles, and promotes the reuse of water resources.

Abstract

This utility model discloses an acid water reuse device for a thickener, relating to the field of phosphogypsum treatment technology. The utility model includes a treatment tank, with an adjustment component in the left chamber and a filter component in the right chamber. The adjustment component includes a hopper fixedly connected to one side of the top of the treatment tank and a stirring rod rotatably connected to the left chamber. A discharge pipe is fixedly connected to the bottom of the hopper, and a feeding pipe is movably connected to the bottom of the discharge pipe via a rotary joint. This utility model adds substances such as lime to the treatment tank through the hopper and feeding pipe to neutralize the acid water. A drive rod rotates the stirring rod and feeding pipe, causing the lime and other substances to mix evenly with the acid water. This solves the problem of inconvenient neutralization and reuse of acid water in existing systems. A sieve removes solid particles from the acid water, and a pressing plate forces the acid water to repeatedly pass through the sieve, solving the problem of inconvenient filtration of acid water in existing systems.
