Dissolving tank for producing polymerization ferric chloride raw material

Abstract

The invention discloses a dissolving tank for producing a polymerization ferric chloride raw material, and belongs to the field of raw material dissolution equipment. The dissolving tank comprises a tank body, a cover body, a stirring mechanism and a discharge mechanism, wherein the tank body of which the top end is opened is buried under the ground; the top end of the tank body is higher than the ground; the cover body is arranged at the top end of the tank body in a covering manner; a feeding tube is arranged on the fixed cover; the stirring mechanism comprises a stirring rod which extends into the tank body, stirring blades which are arranged at the lower end of the stirring rod, and a driving motor which is in driving connection with the upper end of the stirring rod; the discharge mechanism comprises a sucking tube of which the lower extends into the bottom of the tank body, a sucking motor which is arranged on the sucking tube, and a discharge branch tube which is arranged on the sucking tube; a filtering rack is detachably mounted at the top end of the tank body; and the filtering rack is arranged at a feeding part of the opening of the tank body. The dissolving tank is simple in structure, is buried under the ground, is small in space usage and is simple and convenient in material feeding, and impurities in raw materials can be filtered off in the feeding process.

Description

technical field [0001] The invention relates to the field of raw material dissolving equipment, in particular to a dissolving tank for producing polyferric chloride raw materials. Background technique [0002] Polyferric chloride is a new type of high-efficiency inorganic polymer coagulant with a wide range of applications: domestic drinking water, industrial water, domestic water, domestic sewage and industrial sewage treatment, etc. In the production process of polyferric chloride, ferrous chloride salt is usually dissolved in water first, and then hydrochloric acid is added according to a certain proportion to complete the raw material batching. Existing raw material dissolving devices are often installed on the ground, with small capacity and large capacity occupying a large space; and it is troublesome to feed raw materials into the dissolving device. At the same time, impurities are easily mixed into the raw material of ferrous chloride salt, which affects subsequent p...
