Abstract
A vibration-separating sieving machine for the materials in mining, metallurgy, building, chemical and coal industries is composed of screen, flexible connector and vibrator. The screen is formed by overlapping an upper screen and a lower screen, the upper screen and the lower screen are on the same plane, and the upper screen and the lower screen vibrate step by a vibrator, so that the screen is not easy to be blocked by formed materials. The vibration-separating sieving machine has the advantages of high sieving efficiency, good sieving precision, simple structure, low energy consumption, low production cost, simple and convenient operation and maintenance and the like, and is particularly suitable for sieving materials difficult to sieve.
Description
The utility model relates to the screening plant of using in the industry material processing industry such as a kind of mine, metallurgy, building, chemical industry, coal, is specially adapted to difficult screened material or contains the screening of mud material.
The screening plant that uses in industries such as mine, metallurgy, building, chemical industry, coal at present divides by screen size, can be divided into thick, middle grain screening plant and fine sizing equipment.Slightly, middle grain screening plant mainly contains gravity flow screen, vibratory sieve, drum sieve and resonance screens, its compass screen surface mainly contains bar diagrid, woven screen and punching sieve plate.In order to solve the blockage problem of sieve aperture, improve screening efficiency, this class screening plant has vibrating device mostly.The screening efficiency and the production capacity of vibratory sieve are higher, and screening efficiency can reach more than 80%, but for difficult screened material, its screening efficiency sharply descends; The situation of resonance screens and vibratory sieve similar.The compass screen surface of dusting cover is generally made with stainless steel material or rubber, nylon material.From the structure of compass screen surface, compass screen surface is mainly sieve grate bar and woven screen.For alleviating the obstruction of screen cloth, dusting cover generally has vibrating device.But because factors such as material properties and operations, the blockage problem of sieve aperture still exists.The screen cloth of some dusting cover equipment (as flip flop screen) is made by the polyurethane rubber material that can stretch.When work, screen cloth is alternately strained and is relaxed, to avoid material to adhere to screen cloth and to stop up sieve aperture.Though this screening plant sieve aperture is difficult for stopping up, screening efficiency is higher, and screening precision is lower.Generally speaking, the existing common weak point of screening plant is: sieve aperture is easily stopped up by material, even be added with vibrating device, because grating is done synchronous vibration, blockage problem still can't effectively solve, and screening efficiency is difficult to further raising, and the effect of handling difficult screened material is then poorer.
The purpose of this utility model is: by improving the structure of compass screen surface, provide a kind of sieve aperture to be difficult for stopping up, being specially adapted to the novel screening plant of difficult screened material screening.
To achieve these goals, the technical scheme that is adopted is: for varigrained material, compass screen surface can be formed by being the fishbone shape or being upper screen cloth and the staggered stack of lower screen cloth that the strip grating constitutes, upper screen cloth and lower screen cloth are on same plane, and the flexible coupler that is made of latch plate or rubber spring between upper screen cloth and the lower screen cloth connects.Several width and the screen sizes and deciding according to compass screen surface of the group of fishbone shape or strip grating.For the compass screen surface of fishbone shape, grating is staggered, and sieve aperture is square or rectangle.Grating is made with metal material or nonmetallic materials or composite.Under the effect of vibrating mechanism, adjacent grating is done the relative motion perpendicular to screen plane; Whole compass screen surface also can be done straight line or circular motion.Under the dual-vibration effect of compass screen surface, the material on the compass screen surface is by loosening and effectively screening, and sieve aperture is difficult for blocked, thereby improves screening efficiency, solves the screening problem of difficult screened material.
Accompanying drawing 1 is an agent structure schematic diagram of the present utility model.
Accompanying drawing 2 is one group of upper screen cloth a and lower screen cloth b schematic diagram.
Accompanying drawing 3 is screen cloth 1 schematic diagram that upper screen cloth a and lower screen cloth b stack back form.
The utility model will be further described below in conjunction with accompanying drawing.
The utility model mainly comprises screen cloth 1, flexible coupler 2, vibrating device 3, feed box 4 and frame 5.Screen cloth 1 is made up of upper screen cloth a and lower screen cloth b stack.Upper screen cloth and lower screen cloth are made up of the grating that is " fishbone " shape respectively.Lower screen cloth b connects by spring and frame 5, and upper screen cloth a connects with lower screen cloth b by flexible coupler 2.Vibrating device 3 is installed on the steelframe of screen cloth top, and the vibration effect that is produced is directly passed to lower screen cloth b by steelframe, by flexible coupler 2 upper screen cloth a is passed in vibration again.The vibration of upper screen cloth a and lower screen cloth b is the substep vibration.Feed box 4 is fixed on the frame, places the top of upper screen cloth a.
Working method of the present utility model is as follows: material enters compass screen surface by feed box, under the effect of exciting force, the screen cloth of vibration is with the pine that shakes of the material on the screen cloth, and make material obtain the active force that moves along compass screen surface, material less than sieve aperture becomes undersize, becomes oversize greater than the material of sieve aperture.The vibration of the substep of upper screen cloth and lower screen cloth, the effect that not only has loosening material, material is moved along compass screen surface, but also can avoid the obstruction of sieve aperture.
The utility model with existing in, fine sizing equipment compares, and has that sieve aperture is difficult for stopping up, sieve The characteristics such as component efficiency height, screening precision is good, simple in structure, production cost is low, Operation and maintenance are easy, Be specially adapted to the screening of difficult screened material.
