Abstract

The invention discloses a pump mixing type pipeline dosing device for comprehensive utilization of gold cyaniding tailings, and relates to the technical field of mining processing equipment. The device comprises a bottom plate, a plurality of supporting plates, a barrel and a hood, one end of the barrel is fixedly connected with one end of the hood, and the supporting plates are fixedly connectedwith the barrel and the peripheral side face of the hood. By using a medicine adding box, a piston, a medicine cavity and a plug, in the reciprocating sliding process of the piston, a pressure cavitycan suck medicine liquid through a medicine inlet pipe, then when the piston moves leftwards, the plug can be separated from the pressure cavity, then the medicine liquid can enter the barrel, and thestructure can intermittently add medicine to a mixture in the barrel, so that the medicine liquid and raw materials are mixed more sufficiently; when the plug reciprocates, the communicating positionof the barrel and the pressure cavity can be prevented from being blocked; by using an air cavity and an aeration pipe, when the piston slides back and forth, the air cavity continuously compresses air and wind power to enter the aeration pipe, and then aeration is performed through a first one-way valve, so that the reaction of liquid medicine and raw materials is facilitated.

Description

technical field

[0001] The invention belongs to the technical field of mining processing equipment, in particular to a pump-mixing pipeline dosing device for comprehensive utilization of gold cyanide tailings. Background technique

[0002] During the process of cyanidation heap leaching of gold ore, a large amount of tailings will be produced. The tailings will be oxidized if they are piled up for too long, and then weathered and cemented. A small amount of heavy metals is very harmful to the environment and needs to be dealt with in time, and some metals can be recycled in the cyanidation tailings. During recycling, some metals are generally reduced and precipitated through chemical reactions.

[0003] However, when the cyanide tailings are mixed with the liquid medicine, the reaction is often insufficient due to uneven mixing, and the dosing nozzle is easily blocked. In view of the above problems, the present invention proposes a pump mixer for the comprehensive utilizatio...
