Device for mixing ore pulp, medicament and air

Abstract

The invention relates to a device for mixing ore pulp, a medicament and air. The device comprises a mixing mechanism for mixing the medicament with air and a spray nozzle mechanism for mixing the ore pulp, the medicament and the air, wherein the mixing mechanism comprises a gas inlet tube, a medicament inlet tube and a junction pipeline; the junction pipeline is arranged at a junction of the gas inlet tube and the medicament inlet tube and vertically downward; a medicament tank is communicated with the top of the medicament inlet tube; a negative-pressure opening valve is arranged on the upper part of the medicament inlet tube; a medicament atomizing device is further arranged in the medicament inlet tube; the spray nozzle mechanism comprises a spray nozzle and a central pipeline which is arranged on the center of the spray nozzle; a ring-shaped cavity structure is defined by the spray nozzle and the central pipeline; the spray nozzle is in the shape of a funnel and inclined towards an outlet end of the central pipeline; an inlet end of the central pipeline is communicated with an outlet end of the junction pipeline. The device is simple in structure, low in energy consumption and cost, stable to operate and good in mixing effect.

Description

technical field [0001] The invention belongs to the field of pulp pretreatment, and in particular relates to a device for mixing pulp, medicine and air. Background technique [0002] As one of the most important mineral processing technologies, flotation has a wide range of applications, and the pulp pretreatment before flotation is an important factor affecting the flotation effect. Modern flotation research and industrial practice pay more and more attention to the importance of high-efficiency slurry adjustment. Especially for difficult-to-float slime, direct flotation is often ineffective, and pulp pretreatment before flotation is a prerequisite for high-efficiency flotation. Since adding certain chemicals during flotation can effectively activate or inhibit some minerals, the chemicals are usually mixed in the process of treatment. [0003] In the prior art, a chemical addition system is commonly used in the flotation system, and the amount of chemical added is control...

Problems solved by technology

Due to the emulsification, the agent is highly dispersed, forming a misty aerosol, increasing the stability of the flotation agent emulsion, so that it does not form large oil droplets, thereby increasing the contact area between the agent and the pulp, increasing the floatability of minerals, and improving Flotation yield, Chinese patent document CN 103736599 A discloses a kind of emulsification device, and this device comprises a mixing pump, a water source, a water inlet regulator, an air inlet regulator and with emulsifier, and this emulsifier comprises a shell The internal space is divided into a front chamber and a rear chamber by a partition with a narrow hole. When the air-water mixture passes through the narrow hole, it will form an emulsified state due to cavitation. It will greatly improve the efficiency of pulp pretreatment when it is used in flotation. effect, but the device is easy to block the slit and affect the emulsification effect, and the device needs to be adjusted to control the air and water to form a high-pressure saturated gas-liquid, which cannot achieve a stable operation effect

Chinese patent document CN 202105603U discloses an automatic emulsification device for flotation agents. Its motor is placed on the base and connected to the water pump, and the inlet of the water pump is connected to the water inlet pipeline. Mixer, which realizes the mixing and emulsification of medicaments, but the structure of the device is relatively complicated and requires a large amount of electricity, which increases energy consumption and cost
