Abstract

The utility model relates to a component for mechanical devices, which uses a sieving method to separate solid from solid and concretely is a compound screen plate installed on a cylinder bolter for gold-bolting ships. The outer surface of a rubber screen plate distributed with circular screen meshes is covered with a steel back, the cross section of which forms a circular arc shape, and the steel back is made of a whole piece of steel plate. The utility model has the advantages that the rubber screen plate is not easy to be damaged, the service life is enhanced and the fabrication is easy.

Description

Compound screen plate of sylinder bolter for gold-bolting ship

The utility model relates to the parts of a kind of mechanical device that solid is separated with the method for screening from solid, be specially the compound sieve plate that is installed on the gold dredger ore dressing drum sieve.

At present, a kind of selecting and purchasing combination plant into " gold dredger " is generally used in the production of the industrial gold dust of China, wherein roughly selecting of ore in sand form is that drum sieve by rotating is finished, this drum sieve system adopts polylith cross section camber, the surface is furnished with the steel plate of round sieve and makes sieve plate, and welding-on constitutes on a large carrying food-basket shape skeleton.After ore in sand form enters the drum sieve that is rotating from feed end,, granularity is discharged as choosing gold washed ore from sieve aperture less than the sieve aperture sand grains, discharge from the discharge end of rotary strainer as mine tailing greater than stone or other foreign material of sieve aperture by high pressure water washing.The drum sieve sieve plate that adopts steel plate to make, in use, because of sandstone clashes into mutually with steel plate, noise is very big, influences operator's physical and mental health, simultaneously, because steel plate is perishable, makes this sieve plate shorter service life, generally uses after four months and must change.In order to address the above problem, the drum sieve sieve plate that nonmetallic materials (rubber) are made had once appearred, for example CN2066357U discloses a kind of " gold dredger ore dressing drum sieve sieve plate ", steel plate has been prolonged the service life of sieve plate, but the outer surface of this sieve plate is cut into arc by bolting, the surface is the steel backing that the monoblock cast of lattice shape is shaped, the rubber sieve plate that exposes in each lattice of steel backing, because the poor rigidity of rubber slab own, be equipped with many small sircle holes on the rubber slab again, this just makes sieve plate in use, ore in sand form constantly rubs and high pressure water washing with rubber slab, and rubber slab is fragile, need change rubber sieve plate every now and then, influence production efficiency, simultaneously because steel backing is a casting, make comparatively time-consumingly, bother.

The purpose of this utility model just provide a kind of that above-mentioned sieve plate has been improved, rubber slab is not fragile, the replacing number of times that can reduce rubber sieve plate, and steel backing is easy to the drum sieve compound sieve plate of processing and manufacturing.

To achieve these goals, drum sieve compound sieve plate of the present utility model be the outer surface at rubber sieve plate be covered with the cross section in the arc-shaped, by the steel backing that the monoblock steel plate is made, be drilled with circular hole on the steel backing, rubber sieve plate and steel backing fix as a whole with bonding agent.

The compound sieve plate that uses the utility model to provide, its surface is a rubber sieve plate, has elasticity, and the ore dressing noise is reduced greatly, has improved workman's operating environment; The outer surface of rubber sieve plate is covered with the steel backing that cross section monoblock steel plate in the arc-shaped is made simultaneously, rubber sieve plate is not fragile, can improve the service life of sieve plate greatly, can reach service life more than 2 years, reduce the replacing number of times of rubber sieve plate, thereby can enhance productivity; Simultaneously steel backing is made by the monoblock steel plate, makes easily, expense is low.

Accompanying drawing is depicted as the structural representation of the embodiment that the utility model provides, and wherein Fig. 1 is its front view, and Fig. 2 is to cutaway view along Figure 1A-A.(2) are rubber sieve plate among the figure, which is provided with round sieve (1), this sieve aperture has certain taper from inside to outside, the outer surface of rubber sieve plate (2) is covered with cross section steel backing (3) in the arc-shaped, that made by the monoblock steel plate, steel backing (3) be provided with rubber sieve plate (2) on the corresponding circular hole of round sieve (1) (4), circular hole (4) is greater than the sieve aperture (1) on the rubber sieve plate (2), and rubber sieve plate (2) and steel backing (3) become one with bonding agent is bonding; The arc angle of the steel backing of compound sieve plate (3) is 60 °.

Edge by reserving around the compound sieve plate is fixed in welding method on the skeleton of drum sieve, and six compound sieve plates couple together and just constituted a drum sieve.

Claims

1, a kind of gold dredger ore dressing drum sieve compound sieve plate, form by the rubber sieve plate that is provided with round sieve (1) (2), it is characterized in that: the outer surface of rubber sieve plate (2) is covered with cross section steel backing (3) in the arc-shaped, that made by the monoblock steel plate, steel backing (3) be provided with rubber sieve plate (2) on the corresponding circular hole of round sieve (1) (4); Rubber sieve plate (2) and steel backing (3) become one with bonding agent is bonding; The arc angle of steel backing (3) is 60 °.

2, gold dredger ore dressing drum sieve compound sieve plate according to claim 1 is characterized in that circular hole (4) on the steel backing (3) is greater than the sieve aperture (1) on the rubber sieve plate (2).
