Two-stage raw material crushing device for industrial production of zinc sulfate

Abstract

The invention discloses a two-stage raw material crushing device for industrial production of zinc sulfate. The two-stage raw material crushing device comprises a mounting substrate, a crushing box and a discharging structure. The crushing box is mounted on the mounting substrate and can move and be adjusted. The discharging structure is arranged on the mounting substrate and is matched with the crushing box. The crushing box is of a cylindrical structure, and a crushing bin is formed in the top end of the crushing box. The edge of the crushing bin is constructed into a conical side wall, anda discharging cavity communicating with the outside is formed in the bottom end of the crushing bin. The top end of the crushing bin is covered with a sealing cover, and the discharging cavity in thebottom end of the crushing bin is sealed by a sealing gate. Crushing equipment is mounted on the sealing cover and extends into the crushing bin, and multiple edge ridges matched with the crushing binare constructed on the inner wall of the crushing bin in an annular array manner. A grinding mechanism is mounted in the discharging cavity in the bottom end of the crushing bin. The raw material crushing device for industrial production of th zinc sulfate is efficient in crushing, the size of particles is easy to control, separation and collection are carried out as required, and high applicability is achieved.

Description

technical field [0001] The invention belongs to the technical field of zinc sulfate production, and in particular relates to a secondary crushing device for raw materials used in the industrial production of zinc sulfate. Background technique [0002] Zinc sulfate, also known as Hao alum, Zinc alum, is colorless or white orthorhombic crystal or powder at room temperature, has astringency, is easily soluble in water, the aqueous solution is acidic, slightly soluble in ethanol and glycerol. It is mainly used as a raw material for the preparation of pigment lithopone, zinc barium white and other zinc compounds. It is also used as a nutritional material when animals are deficient in zinc, an animal husbandry feed additive, a zinc fertilizer (trace element fertilizer) for crops, and an important source of man-made fibers. Materials, electrolytes for electrolytic production of metallic zinc, mordants in the textile industry, pharmaceutical emetics, astringents, fungicides, wood an...

Problems solved by technology

[0003] The Chinese patent document with the publication number CN204892010U discloses a raw material crushing equipment for the production of zinc sulfate monohydrate, which proposes a cylindrical crushing structure arranged symmetrically with the axis of the cylinder and a crushing belt to cooperate with each other to achieve fine crushing and grinding. Then its broken size cannot be controlled, it is only used as a broken structure, and the size of the broken particles cannot be limited, and the size of the broken particles determines the contact area with the solution and thus determines the speed of the reaction

[0004] Therefore, a secondary crushing device for raw materials used in the industrial production of zinc sulfate has been proposed, which has solved the problem that the existing crushing equipment cannot determine the particle size.
