Abstract
The invention discloses a dedusting method for a conveyor belt of a concentrating mill and a device thereof. A plurality of piezoelectric ultrasonic atomizing nozzles are evenly arranged at the top of a belt cover. The piezoelectric ultrasonic atomizing nozzles are connected with an ultrasonic power source, a water supply system and an air pressurization system. The basic principle of the dedusting method for the conveyor belt of the concentrating mill is that water is atomized to be compact water mist of which the diameter of water drops is 1 micron to 100 microns through the piezoelectric ultrasonic atomizing nozzles, and the space, above the conveyor belt, in the whole belt cover is filled with the water mist. The compact water mist and dust descend and cover the surfaces of materials after absorption and aggregation, and thus the effects of dedusting and dust suppression are achieved. According to the dedusting method for the conveyor belt of the concentrating mill and the device thereof, the dedusting effect is obvious, the implementation is easy, the operation and maintenance are simple and convenient, the energy consumption is low, the water consumption is low, no dedusting agent is added, and equipment is prevented from corrosion. No influence is produced on the follow-up concentrating operation. The environment of a conveyor belt platform of the concentrating mill can be effectively improved.

Technical field
The present invention relates to a kind of dust collection method, particularly relate to the dust collection method of a kind of ore dressing plant travelling belt.The invention still further relates to and realize this device for the dust collection method of ore dressing plant travelling belt.
Background technology
In ore dressing plant, ore materials is generally operated between distinct device or operation by travelling belt.Because ore is with producing vibration and friction in belt movement process, and form disturbance to surrounding air, therefore can generate and kick up a large amount of dust, with air-flow effusion diffusion.These dust have that granularity is little, concentration greatly, not free settling, easily form the features such as secondary pollution.If do not take safeguard procedures to be controlled dust, the operating environment in meeting gross pollution workshop, harm worker's is healthy.
Owing to being kept in motion when travelling belt runs, sealed environment cannot be formed, relatively difficult to the improvement in motion dirt source, main employing wind-force dedusting and watering humidification two kinds of dust-removing methods at present, effect is not ideal, wind-force dedusting arranges to take out dust hood on belt, utilizes to take out dirt blower fan and taken away by exhaust column by dust and collect in a place.Although this method can play and certain take out dirt cleansing action, owing to existing, to take out dust hood sealing effectiveness poor, and power of fan is large, and energy consumption is high, and efficiency of dust collection is low, and equipment investment is large, installs the deficiencies such as complexity.Watering humidification arranges shower water above belt, makes it no longer produce a kind of processing method of dust after being drenched by ore.Because shower water is circulating water, the active area sprayed on ore is very little, whole mineral surface therefore will be made moistening, must use a large amount of water.Although this method is simple, water consumption is large, and the ore drenched very easily argillization bonding on belt, damage belt equipment, and for ore materials aqueous ingredients being had to the situation of strict restriction, watering humidification can not be suitable for completely.
Therefore, still there are problems in the dedusting technology of above-mentioned ore dressing plant travelling belt and need to improve.
Summary of the invention
First technical matters to be solved by this invention be to provide a kind of efficient, energy-conservation, easy enforcement and on subsequent production process procedure without impact the dust collection method for ore dressing plant travelling belt.

Adopt the dust collection method for ore dressing plant travelling belt and the device thereof of technique scheme, evenly arrange piezoelectric ultrasonic atomization nozzle at the belt housing top of travelling belt, the spacing of adj acent piezoelectric ultrasonic wave atomizing nozzle is 50cm-150cm.Piezoelectric ultrasonic atomization nozzle connects with ultrasonic power, water supply system and supercharging air system.Ultrasonic power is that piezoelectric ultrasonic atomization nozzle is powered, and adjustment line frequency can change the water smoke drop diameter that piezoelectric ultrasonic atomization nozzle produces.Water supply system is that piezoelectric ultrasonic atomization nozzle evenly supplies water, and changes mist amount by regulating pondage.Supercharging air system is piezoelectric ultrasonic atomization nozzle air feed, by the spray regime and the distance that regulate tolerance size to change atomized water.Groundwork of the present invention is the fine and close water smoke utilizing piezoelectric ultrasonic atomization nozzle to atomize water into drop diameter 1 micron ~ 100 microns, be full of the whole belt housing above travelling belt, fine and close water smoke and adsorbing powder dust decline after reuniting, be covered to material surface, thus reach the effect of dedusting and dust suppression.Dust removing effects of the present invention is remarkable, and easy to implement, simple and convenient operation and maintenance, energy consumption is low, and water consumption is little, does not add dedusting medicament, not etching apparatus, can not have an impact to follow-up ore-dressing practice, effectively can improve the environment of ore dressing plant travelling belt platform.
The present invention has the following advantages:
1, the present invention is easy to implement, can be widely used in the dedusting of travelling belt of different mineral, different model specification, simple and convenient operation and maintenance by changing the how many and coverage of the quantity of atomizer, droplet size, mist amount.
2, because water droplets diameter is little, closeness is large, wide coverage, and large with dust area of contact, contact probability is high, makes dust can effectively sedimentation.Meanwhile, the area of contact of water smoke and mineral surface is large and evenly, makes mineral surface can be evenly moistening and can not argillization, effectively improves the environment of travelling belt platform.
3, owing to adopting atomized water, water consumption is little.Relative to wind-force dedusting, do not have the mechanical equipments such as large-size machine, energy consumption is little.
