Device for producing food calcium carbonate by separating calcium ions from inside

Abstract

The invention discloses a device for producing food calcium carbonate by separating calcium ions from inside, and the device comprises a driving motor, a feeding cylinder, an upper cover, a treatmentcylinder, a filter tank, a separating box, a slag outlet, a sedimentation cylinder, a wetting tube, an opening and closing plate, an inner stripping device, a ventilation tube and a heating rod. The driving motor is fixed on the left end above the upper cover through a frame and is electrically connected with the treatment cylinder through a wire. After gypsum is softened, gypsum is penetrated from both sides through a first cut-in column, a second cut-in column, a first reverse cut-in column and a second reverse cut-in column, so that the inner layers of the gypsum are penetrated through layer by layer, dilute hydrochloric acid is outputted through in-pair liquid holes, the dilute hydrochloric acid is reacted with the gypsum to form a calcium chloride solution, the calcium ions distributed in the inner layers of the gypsum are extracted, the gypsum is reacted into smaller residues, and by full use of the calcium ions in the gypsum, the production of the calcium carbonate is increased.

Description

technical field [0001] The present invention relates to a kind of equipment of producing calcium carbonate, relate in particular to a kind of equipment of producing food calcium carbonate that the inside separates calcium ion. Background technique [0002] Calcium is a nutrient required by the human body, among which calcium carbonate is more easily absorbed by people, people can produce calcium carbonate through gypsum, but the current patent number is CN201320002120.6 A kind of equipment for producing food-grade calcium carbonate from gypsum, which directly converts When the reaction solution is poured on the gypsum, it can only be dissolved layer by layer, and the calcium ions inside are difficult to separate, and calcium ions will still exist in the residue, resulting in waste. The current technical considerations are not comprehensive and have the following disadvantages: [0003] The divalent calcium ions inside the gypsum are distributed in layers, and the internal ca...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a kind of equipment for producing food calcium carbonate with internal separation of calcium ions, so as to solve the problem that the divalent calcium ions inside the gypsum are in a layered distribution state, and when the reaction solution reacts The internal calcium ions are not easy to react, so that the internal calcium ions are lost with the residue and cannot be extracted, resulting in a waste problem
