Abstract
The utility model discloses a roller grading sieving machine. The utility model falls the whole sieve face into a plurality of sections. Different angles of the inclination are arranged in each section. Therefore, the accumulation and blockage of the material are avoided. The sieve face has high utilization rate and reasonable distribution.
Description
The utility model relates to a kind of stock grading screening plant that is applied to industries such as coal, mine, especially a kind of roller bearing classifying screen extension set.
At present industries such as coal, mine to the stock grading screening operation in, widespread usage be the roller type screening machine.It forms one by some sieve axle lateral arrangement and sieves the plane, and the sieve axle rotates the promotion material by certain rotating speed to same direction and flows to discharging opening from feeding mouth, and material is finished sieve classification in flow process.The screening machine of this integral planar type compass screen surface, because feeding mouth place and discharging opening place have the rotating speed of sieve axle identical, the flowing velocity of material is certain, causes the material thickness on the feeding mouth place compass screen surface big, along with the advancing and sieve of material, material thickness diminishes gradually.This integral planar type compass screen surface causes solid accumulation easily, clogging occurs in big conveying capacity system.Feeding mouth place Flow of Goods and Materials speed easily bonds sieve aperture and reduces screening efficiency than big or the bigger material of moisture content viscosity slowly.The compass screen surface utilization rate is low, the screening efficiency unreasonable distribution.
The purpose of this utility model provides a kind of novel classifying screen extension set, and it makes full use of the sieving actoion at each position of compass screen surface, has avoided accumulation, jam and the viscous material of material sticking stifled.
The purpose of this utility model is achieved in that by some sieve axles forms the segmented compass screen surface, along the inclination angle of each section compass screen surface on the Flow of Goods and Materials direction from large to small, forms change inclination angle segmentation compass screen surface.Distance between the feeding mouth section sieve axle is bigger than the distance between other section sieve axle.
Because screen(ing) machine feeding mouth place screen angle is big, makes the material that enters from feeding mouth flow into next section compass screen surface fast, has avoided the accumulation of material at feeding mouth section compass screen surface.Speed along with the variation material of screen angle in the Flow of Goods and Materials process is gradually slow, and material progressively screening shunting on each section compass screen surface simultaneously forms to be similar to and sieving the high screening with constant bed thickness of screening efficiency in theory.Because Flow of Goods and Materials speeds up after increasing screen angle, the possibility that has reduced the material bonding has also improved the screening treating capacity of unit are compass screen surface.The bigger sieve of sieve distance between axles of the leading portion compass screen surface of sticking stifled possibility maximum is effective.
Fig. 1 is an overall schematic of the present utility model
Fig. 2 is a sieve axle schematic diagram of the present utility model
Below in conjunction with embodiment and accompanying drawing the utility model is described further:
The utility model is made up of case 1, transmission device 2, sieve axle 3, dust cover 5.Be set with some sieve sheets on the sieve axle 3, be installed on the screen box body, adjacent two sieve axles and be sleeved on sieve sheet on the axle at a certain distance and form a certain size sieve aperture by the bearing supporting at two ends.Transmission device 2 is installed in an end of screen box, drives the rotation of sieve axle by motor by decelerator and travelling gear or driving chain.Whole compass screen surface is divided into three sections, is made up of some sieves axle for every section, and by some sieves screen angle maximum of forming, along the direction of Flow of Goods and Materials, the inclination angle of every section compass screen surface reduces one by one at the feeding mouth place.Being provided with dust cover 5,4 above screen box 1 is the screen(ing) machine charging aperture, and 6 is the discharging opening of screen(ing) machine.
In addition to the implementation, also compass screen surface can be made concave arc shape, promptly be formed the compass screen surfaces of an arcs of recesses by some sieve axles, the compass screen surface of this arcs of recesses is big at the tangent slope at screen(ing) machine feeding mouth place, reduces gradually along the tangent slope of Flow of Goods and Materials direction arcs of recesses compass screen surface.
Claims (3)
1. a roller bearing classifying screen extension set is made up of screen box, sieve axle, transmission device, and it is characterized in that: the compass screen surface of being made up of the sieve axle is divided into several sections, and every section compass screen surface is made up of some sieve axles, the direction of every section compass screen surface along feeding mouth to discharging opening, and the inclination angle reduces one by one.
2. screening machine according to claim 1 is characterized in that: the distance between feeding mouth place compass screen surface two roller bearings is bigger than the distance between other section compass screen surface two roller bearings.
3. screening machine according to claim 1 is characterized in that: by some compass screen surfaces that form an arcs of recesses that sieve, the tangent slope of the direction arcs of recesses compass screen surface along feeding mouth to discharging opening reduces gradually.
