Dedusting method and dedusting device for concentrating mill screening equipment

Abstract

The invention discloses a dedusting method and a dedusting device for concentrating mill screening equipment. A plurality of atomized water inlets are formed on the side wall of a box at each layer of a vibrating screen, a piezoelectric ultrasonic atomizing nozzle is arranged at the atomized water inlet, and the piezoelectric ultrasonic atomizing nozzles are connected with an ultrasonic power supply, a water supply system and an air pressurization system. The basis principle of the method and the device is that the piezoelectric ultrasonic atomizing nozzles are used for converting water mist into dense water mist with water drop diameter of 1 micrometer-100 micrometers, and the dense water mist enters a vibrating screen through an atomized water inlet in the side wall of the vibrating screen and fills up the whole tank of the screen cloth of the vibrating screen. The dense water mist adsorbs dust for clustering and then drops to cover the surface of the material, so as to achieve the effects of dust removal and dust suppression. The dedusting method and dedusting device are remarkable in dedusting effect, easy to implement, simple and convenient to operate and maintain, low in energy consumption, and small in water consumption, is not added with dedusting drugs, cannot corrode equipments, has no influence on subsequent mineral separation operation, and can effectively improve the environment of a concentrating mill screening operation platform.

Description

technical field [0001] The invention relates to a dust removal method, in particular to a dust removal method for screening equipment in an ore dressing plant. The invention also relates to a device for realizing the dust removal method of the screening equipment of a mineral processing plant. Background technique [0002] The crushed ore in the concentrator is generally classified by screening equipment, and different particle sizes are processed separately. The most commonly used screening equipment is the vibrating sieve, which has different types such as single-layer sieve, double-layer sieve and multi-layer sieve. Due to the high frequency vibration and friction of the ore in the vibrating screen with the screen, a large amount of dust will be generated and raised, and will escape and diffuse with the airflow from the feed port of the vibrating screen and the discharge port of each particle size. These dusts have the characteristics of small particle size, high concen...

AI Technical Summary

Problems solved by technology

Although this method is simple and easy to implement, it consumes a lot of water, and the wet ore is easily muddy and bonded in the vibrating screen, causing the screen to be blocked. For the situation where there is a strict limit on the water content of the ore material, watering and humidification are completely not applicable
