Acid pickling wastewater treater

Abstract

The invention discloses an acid pickling wastewater treater. The structure of the treater comprises an automatic reagent feeding device, a guardrail, a ladder, a blow off pipe, supporting legs, a platform, a body and a drain pipe, wherein the supporting legs are vertically welded with four corners of the bottom of the body. The treater has the beneficial effects that the treater is provided with the automatic reagent feeding device, has an automatic reagent feeding function, does not need manual operation, automatically starts the automatic reagent feeding device to perform automatic reagent feeding through the matching of a PH probe when a detected value is smaller than a set value, automatically stops the automatic reagent feeding device to stop reagent feeding when the detected value isgreater than the set value, can uniformly stir reagents before automatic reagent feeding through the setting that a worm and gear rotating mechanism rotates to drive components, such as a reciprocating motion mechanism and a stirring mechanism, is more beneficial to the neutralization reaction between the reagents and water, reduces workload, improves the work efficiency, is accurate in blending,and is beneficial to the improvement of the wastewater treatment effect.

Description

technical field [0001] The invention relates to the field of pickling wastewater treatment, in particular to a pickling wastewater treatment machine. Background technique [0002] Pickling wastewater is the wastewater generated when sulfuric acid, nitric acid, hydrochloric acid, hydrofluoric acid and phosphoric acid are used for pickling treatment in order to remove metal surface oxides. Most of the wastewater comes from steel plants or electroplating plants. The pH value is generally below 1.5 and is strongly acidic. The wastewater is treated by neutralization. The neutralizers often used are lime, dolomite, magnesium oxide, and retardation separation. [0003] Due to the imperfection of the current technology, it is necessary to first test the pH of the water quality, and then add a corresponding amount of medicine to neutralize the water quality according to the pH value. This process is manual and does not have the function of automatic dosing. The workload is heavy. , ...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the imperfect technology of the prior art, which needs to firstly detect the pH of the water quality, and then add a corresponding amount of medicament to neutralize the water quality according to the pH value. This process is manual operation and does not have automatic addition. The function of the medicine, the workload is heavy, the work efficiency is low, the reconciliation is not accurate, and the problem affecting the treatment of wastewater is provided. A pickling wastewater treatment machine is provided.
