Abstract
The invention relates to crude and fine ore grain separation in the processes of grinding, rolling, ball-milling, crude and fine ore grain separation and the like of raw ores in a mineral separation process. The following two separation forms exist in the crude and fine ore grain separation process: wet separation and dry separation. The invention provides a negative pressure cyclone ore grain screening machine, namely a dry totally closed negative pressure environment-friendly and energy-saving machine used for crude and fine ore grain separation.
Description
Technical field:
The present invention relates in the ore-dressing technique process by the tcrude ore warp: broken, roll, the thickness ore particle sorting in ball milling, the sorting of thickness ore particle etc. technical process, two kinds of sorting forms are arranged in thickness ore particle sorting process; 1, is wet separation.2, be dry-type separation.What here will set forth is machinery----the negative pressure cyclone ore particle screening machine of the thickness ore particle sorting of the totally-enclosed negative pressure and environment protection energy-saving type of a kind of dry type.
Background of invention:
In thickness ore particle sorting process; In the applied machinery of dry type thickness ore particle sorting, adopt the oscillatory type screening machine at present mostly, the oscillatory type screening machine has advantages such as practical, that screening effect is reliable, but it is very big to exist the dust environmental pollution that consumes energy is big, noise big, start when vibrating owing to the entrained breeze of ore deposit particle, and health of operators has been caused harm, and how vast ore dressing personnel expect to have is namely divided ore dressing efficient height, not only energy-conservation but also environment do not had a birth of the ore particle separator that pollutes.So invented----a kind of environmental protection negative pressure cyclone ore particle screening machine at this theory.
Summary of the invention:
Environmental protection negative pressure cyclone ore deposit screening machine is the used machinery of a kind of method that belongs to the sorting of dry type thickness ore particle: this method synthesis Pneumatic Conveying Technology and cyclone technique, used the power source of negative-pressure vacuum as the sorting of thickness ore particle and conveying, and according to hydrodynamics vortex theory: vortex also claimed sometimes.Referring to that the very little cylinder of a kind of radius rotates in stationary fluid causes that surrounding fluid makes the flow phenomenon of circular motion.There is the compact district of a vorticity general vortex inside, claims vortex core, and its motion class is like the rigid body rotation.Above-mentioned cylinder is namely similar in appearance to the vortex core of vortex.In its outside, peripheral speed and the radius of fluid are inversely proportional to; In its inside, then be directly proportional with radius, peripheral speed is zero on center of vorticity.Vortex is the important flow phenomenon during aircraft streams, and utilizes the natural phenomena of this precession ascension: the basic thought of the lighter material of weight being lifted that Here it is to the high-altitude is stayed weight than heavy substance below and designed negative pressure cyclone ore particle separator.Difference is; Designed is the negative pressure cyclone: at first the air in the cyclone carrier is removed relative 1 atmospheric pressure differential of utilizing carrier and ore particle storeroom, delivered to the appointed place; The appointed place has two: 1 coarse grain place.1 particulate place.That is: be that the starting point of ore particle sorting forms cyclone along the tangential direction end of cylindrical tube with ore particle and Air mixing body with former material outlet, it drops to the not enough senior general of lifting force of the heavier cyclone that particle is big the coarse fodder storehouse and (is called: down going channel), the fine grained that through the air swirl that produces along two groups 4 the cyclone power-assisted airports consistent with the tangent line of cylindrical tube the coarse granule body is carried in the process that falls purges and breaks away from, and is lifted to the passage in fine grained storehouse by cyclone (to be called: data feedback channel).The particle that the screen device that a cone body of falling the garden has been installed in data feedback channel is used for screening predetermined particle specification, meet the screen cloth specification can continue to enter the fine grained storehouse along data feedback channel, the screen device bottom end socket that has designed a blow device and the cone body of falling the garden in the screen device for the particle shutoff cone body of falling the garden that prevents data feedback channel adopts the taper butterfly valve as end socket (the taper butterfly valve is controlled with pneumatic system), the particle that cleaning that can be regular precipitates.
The advantage of negative pressure cyclone ore particle screening machine:
As mentioned above: the first, this course of work (the power-assisted source of the gas of quoting also is the formed wind regime of air that is caused ecto-entad by vacuum system and outside differential pressure) of under closed conduit and vacuum action, realizing fully, to surrounding environment without any pollution.The second, the machinery of the manufacturing energy is vacuum machine, its function very simple motion pay seldom compared with the vibratory sieve formula want much less (vibratory sieve not only side-to-side movement and also move up and down, kinematic pair is many, mechanical friction power is big), so be the laborsaving merit of economizing again, saved a large amount of energy by contrast.Three, production efficiency height: the characteristics of being discussed by ' the second ' bar determine that the time of using with vibratory sieve reduces greatly, so the production efficiency height under identical output.Four, design system's deposited particles scavenge system and can monitor particle under the collection of removing screening system constantly automatically.Five, noise is little------
