Zinc sulfate solution pH adjusting device for removing chlorine from zinc sulfate solution

Abstract

The invention discloses a zinc sulfate solution pH adjusting device for removing chlorine from a zinc sulfate solution. The device comprises a pH adjusting box, a cover plate, a mounting sleeve, a stirring shaft, a communicating pipe, an aeration disc, a rotating joint, a lifting assembly, a rotating assembly, a first sampling pipe, a second sampling pipe, a third sampling pipe, a driving motor, adriving shaft, a spiral conveying paddle, a liquid outlet and a liquid discharging bin, a sealing cover used for sealing an opening of the liquid discharging bin is hinged to the liquid discharging bin, and the sealing cover is driven by a turnover assembly to turn over along the hinged position of the sealing cover and the liquid discharging bin. The device has the beneficial effects that the stirring motor drives the stirring shaft to rotate, then the communicating pipe rotates in the pH adjusting box, the stirring purpose is achieved, the flowing efficiency of a pH adjusting agent is improved, in addition, compressed air generated by external air compression equipment is conveyed into the aeration disc through the rotating joint, aeration is conducted through the aeration disc, and therefore, bubbles are generated in the zinc sulfate solution, and the stirring efficiency of the pH adjusting agent is improved by utilizing the floating of the bubbles.

Description

technical field [0001] The invention relates to the field of zinc sulfate processing equipment, in particular to a zinc sulfate solution pH adjustment device used for removing chlorine from the zinc sulfate solution. Background technique [0002] Zinc sulfate is an inorganic substance with the chemical formula ZnSO4, colorless or white crystals, granules or powder, also known as alumite, odorless and astringent. Weathering in dry air, lose all crystal water at 280°C. Pure zinc sulfate will not turn yellow when stored in the air for a long time, and it will lose water in dry air to form a white powder, and there are many hydrates. [0003] Zinc sulfate is mainly used as a raw material for producing pigment lithopone, lithopone and other zinc compounds, and also as a nutrient for animals when zinc is deficient, animal husbandry feed additive, zinc fertilizer (trace element fertilizer) for crops, man-made fiber Important materials for electrolytic production of metal zinc, el...

AI Technical Summary

Problems solved by technology

[0004] During the preparation of zinc sulfate, the chlorine element in zinc sulfate needs to be removed, but in the process of chlorine removal, the added chemicals will cause the overall pH value of the zinc sulfate solution to change, so it is necessary to use a pH regulator to adjust the pH value. Adjustment, that is, pour the zinc sulfate solution into the pH adjustment box, and then pour the pH regulator into the pH adjustment box, but because the pH regulator cannot penetrate into the lower layer of the zinc sulfate solution in the zinc sulfate solution, the pH value adjustment efficiency will be reduced. lower
