Device for washing cuprous chloride precipitate by using anhydrous ethanol for removing chlorine from zinc sulfate solution

Abstract

The invention discloses a device for washing cuprous chloride precipitate by using anhydrous ethanol for removing chlorine from a zinc sulfate solution. The device comprises a chlorine removal bin, abin cover, a turnover driving assembly, a filter plate, a washing cavity, a liquid storage cavity, filter holes, a vertical movement driving assembly, a rotating sleeve, a transmission assembly, a rotating shaft, a communicating pipe and spray heads, wherein the upper end of the rotating shaft penetrates out of the rotating sleeve and is rotationally connected with a rotating joint, and the rotating joint is driven by a lifting assembly to move vertically so as to drive the spray heads to move up and down. The device has the beneficial effects that through the rotation of the rotating shaft, the plurality of spray heads can rotate in the axial direction of the rotating shaft, so that the washing range is increased under the condition that the number of the spray heads is fixed; meanwhile,the lifting assembly is arranged to drive the spray heads to move up and down, so that the washing strength of the spray heads can be improved, and the washing efficiency is further improved; and thevertical movement driving assembly is arranged to drive the filter plate to move vertically, and the vibration of the filter plate is utilized, so that the cuprous chloride precipitate is prevented from being accumulated on the filter plate, and the washing effect is prevented from being influenced.

Description

technical field [0001] The invention relates to the field of flushing equipment, in particular to a device for flushing cuprous chloride precipitates with absolute ethanol for removing chlorine from a zinc sulfate solution. Background technique [0002] Chinese Invention Patent Publication No. CN109371259A discloses a method for removing chlorine from zinc sulfate solution. The steps are: adding concentrated sulfuric acid to the zinc sulfate solution to adjust the pH; adding ascorbic acid, and then adding cuprous oxide for chlorine removal to form chlorine Cuprous chloride precipitation, after filtering, take the filtrate for later use; wash the cuprous chloride precipitation with absolute ethanol, combine the washing solution and the filtrate to obtain a mixed solution; add an equal volume of organic amine to the mixed solution, extract, stand and separate, The chlorine-removed zinc sulfate solution and the chlorine-rich organic phase are obtained; the chlorine-rich organic...

Problems solved by technology

[0003] Above-mentioned prior art has introduced the processing method of washing cuprous chloride precipitation by dehydrated alcohol, but the equipment that is used for dehydrated alcohol washing cuprous chloride precipitation generally just washes cuprous chloride precipitation by the shower nozzle of fixed installation at present , this method reduces the range of flushing, that is, creates a flushing blind area and reduces flushing efficiency
