A device for mixing ore pulp with medicament and air

Abstract

The present invention relates to a device for mixing ore pulp with medicament and air. The device is divided into a mixing mechanism for mixing medicament and air and a nozzle mechanism for mixing ore pulp with medicament and air; the mixing mechanism includes Trachea, medicine feeding pipe and converging pipeline, the said converging pipeline is arranged at the confluence of the air intake pipe and the medicine feeding pipe and is vertically downward; There is a negative pressure to open the valve, and a drug atomization device is also provided in the drug inlet pipe; the nozzle mechanism includes a nozzle and a central pipe arranged at the center of the nozzle, and the nozzle and the central pipe form a ring-shaped cavity structure ; The nozzle is funnel-shaped and inclined towards the outlet end of the central pipe, and the inlet end of the central pipe communicates with the outlet end of the converging pipe. The invention has simple structure, low energy consumption and cost, stable operation and good 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 medicament addition system is commonly used in the flotation system, and the amount of medicament added is con...

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 CN103736599A 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 housing, Its 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 effect of pulp pretreatment when applied in flotation. However, 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 CN202105603U discloses a flotation agent automatic emulsification device. 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. device, 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
