Abstract
The utility model discloses a self-vibration screen, comprising a transverse beam and a plurality of grate bars. The grate bars are distributed uniformly at intervals. One end of each grate bar is horizontally fixed on the transverse beam and arranged in perpendicular to the transverse beam, the other end is suspended. The utility model is characterized in that the grate bar uses materials with a certain elasticity and flexibility to make circular or trapezoid cross-section, and the cross-section of the transverse beam is U-shaped. Each of the two groove walls of the U-shaped groove is provided with a row of mutually corresponding bar holes. The bottom part in the groove is provided with a press plate with elastic elements. The grate bar is pressed on the elastic element and threaded into the mutually corresponding bar hole, pressed tightly and fixed through the locking screw nut on the screw bolt which passed through the bottom part of the groove. The utility model has the advantages of no cementing and screen blinding, high screening efficiency and long service life.
Description
The utility model relates to a kind of compass screen surface, is specially adapted to the Self-vibration screen on the screening plants such as gravity flow screen, vibratory sieve and rotary screen.
The compass screen surface that is installed at present on the various screening plants has elastomeric sieving plate, cast steel compass screen surface, rod compass screen surface, establishment compass screen surface and broach compass screen surface etc. a variety of, their common drawback is the little from amplitude of compass screen surface, material is easy bonding plug-hole on compass screen surface, influence the service life of screening efficiency and compass screen surface, the scope of application is limited.
The purpose of this utility model provides a kind of big from amplitude, the material plug-hole that on compass screen surface, can not bond, and the screening efficiency height, the scope of application is wide, the Self-vibration screen that the life-span is long.
Task of the present utility model is finished as follows, and it comprises a crossbeam and some gratings, and each grating spacing is uniform, and an end horizontal vertical is fixed on the crossbeam, and the other end is unsettled, it is characterized in that; Grating selects for use the material of certain elasticity and toughness to make cross section for circular or trapezoidal, the cross section of crossbeam is a U-shaped, respectively have one to arrange two corresponding cylindrical voids on two cell walls of U-lag, the groove inner bottom part is equipped with pressing plate, have elastic component on the pressing plate, each grating is pressed in and pierces into two corresponding cylindrical voids on the flexible member, is fixed with the locking nut on the bolt that passes bottom land, in order to prevent the axial motion of grating, be provided with the retaining baffle plate in the grating termination in the crossbeam outside.In order to adapt to the various materials of screening, the compass screen surface that reclines can connect the screen cloth or the sieve plate of all size.
The utility model has following effect: because grating one end is connected and fixed by flexible member and crossbeam, the other end is unsettled, grating itself is again to make with elastomeric material, so compass screen surface has the self-vibration performance, when material was fallen on the grating, compass screen surface promptly vibrated, and was upspring greater than the material of sieve aperture, separate downwards along the compass screen surface upslope, then see through sieve aperture less than the material of sieve aperture and separate.Grating ceaselessly vibrates during screening, the compass screen surface plug-hole that can not bond, and the screening efficiency height is easily changed and maintenance because of grating again, so long service life.It is not only applicable to have as vibratory sieve, rotary screen etc. the screen(ing) machine of certain kinetic energy and makes compass screen surface, and being applicable to as gravity flow screen etc. does not have the screen(ing) machine of kinetic energy to make compass screen surface yet, applied widely.
Fig. 1 is a structure vertical view of the present utility model;
Fig. 2 is a crossbeam transverse sectional view of the present utility model.
In the accompanying drawing, grating 1, flexible member 2, crossbeam 3, retaining baffle plate 4, pressing plate 5, bolt 6, locking nut 7.
Shape of the present utility model such as same wooden comb, by grating 1 with rounded trapezoidal or the square or rectangle of certain elasticity and toughness cross section, horizontal vertical is fixed on forms a compass screen surface on the crossbeam 3, the width of crossbeam 3 is wideer slightly than compass screen surface, the top centre of crossbeam 3 is dead slots, cross section takes the shape of the letter U, by bottom land pressing plate 5 is housed in the groove, it above the pressing plate 5 flexible member 2, one row, two corresponding cylindrical voids are uniformly at intervals respectively arranged on two cell walls above the flexible member 2, one end of each grating 1 pierces into two corresponding cylindrical voids respectively, withstands below the pressing plate 5 and the locking nut 7 that passes on the bolt 6 of bottom land is tightened fixing with several.In order to prevent grating 1 axial motion, grating 1 end in crossbeam 3 outsides is connected with retaining baffle plate 4.In the use, also can be according to screening material needs, the screen cloth of required specification or the sieve plate compass screen surface that reclines is fixed, carry out required screening.When being used for fixing sieve and waiting no kinetic energy screening plant, the compass screen surface inclination angle should be spent less than 60 greater than 30 degree.When being used for vibratory sieve etc. the screening plant of kinetic energy being arranged, the compass screen surface inclination angle should be greater than 15 degree, less than 40 degree.Also can be according to the length of screen frame, select for use one to several compass screen surface secured in parallel of the present utility model in a big screen frame, sieve, operating efficiency is higher.
