Abstract

The invention discloses a premixer for acid and ore, which belongs to the technical field of the design and manufacturing of metallurgical material production equipment. The provided premixer has the advantages of sufficient premixing and accurate premixing input amount. The premixer comprises a material input system, a concentrated sulphuric acid input system, and a continuous acid-ore premixing and output system, an ore input port and an acid liquor input port are respectively arranged at the head end of the continuous acid-ore premixing and output system, and a premixed material output port is arranged at the tail end of the continuous acid-ore premixing and output system; the material input system and the concentrated sulphuric acid input system respectively communicate with the continuous acid-ore premixing and output system via the ore input port and the acid liquor input port; and ore and concentrated sulphuric acid which need to be premixed are respectively and simultaneously inputted into the continuous acid-ore premixing and output system by the material input system and the concentrated sulphuric acid input system according to set speeds, continuously uniformly mixed and continuously outputted from the premixed material output port.

Description

technical field

[0001] The invention relates to a premixing device, in particular to a premixing device for acid ore, and belongs to the technical field of design and manufacture of metallurgical raw material production equipment. Background technique

[0002] The mixing of solid materials and liquid materials is a common chemical production unit in the chemical industry. In the production of titanium dioxide by sulfuric acid method, the premixing of concentrated sulfuric acid and titanium concentrate is also an important link in the acid hydrolysis process of titanium concentrate. Its purpose is to use concentrated sulfuric acid to wet the titanium concentrate, mix it well, enter the acidolysis reactor, and carry out the acidolysis reaction under the trigger of water or waste acid. At present, the acid ore intermittent premixing method is generally used in the production of sulfuric acid titanium dioxide. In the premixing tank with stirring and jacket cooling, a certain amo...
