Abstract
The utility model discloses a screen plate for the ore-dressing cylindric screen of a gold exploitation ship which is formed by rubber. Cross sections are fixed into arc shape by bolts on the surface of the utility model; the surface is the steel back of lattice shape, replacing a steel screen plate. The utility model has the advantages of low noise, long service life, etc.
Description
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 sieve plate that is installed on the gold dredger ore dressing cylinder.
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, and this drum sieve system adopts polylith cross section camber, and 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 sand grains of sieve aperture, discharge from the discharge end of drum sieve 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,, make this sieve plate shorter service life, generally use after four months and must change because steel plate is perishable.
The purpose of this utility model is exactly the drum sieve sieve plate that a kind of nonmetallic materials of design are made, thereby the noise when reducing ore dressing prolongs service life of sieve plate simultaneously.
The utility model is achieved in that using the sieve plate of above-mentioned drum sieve instead the rubber material makes, consider the rubber softness, poor rigidity, so need to be covered with the steel backing of cross section camber at the outer surface of sieve plate, steel backing is made of the flat material, lattice shape is made on the surface, exposes the sieve aperture of sieve plate in each lattice, uses the bolting one between steel backing and the rubber sieve plate.
The rubber sieve plate that uses the utility model to provide, flexible because of rubber, the ore dressing noise is reduced greatly, improved workman's operating environment; Simultaneously, because of the rubber wear-resisting corrosion resisting property is good, also improved the service life of sieve plate greatly.Through test, plate thickness can reach more than 1 year in the time of 20 millimeters its service life, the steel backing of its outer surface, be fixed on the skeleton of drum sieve (with bolting or welding all can) after, generally can forever use, as long as change rubber sieve plate to after date.
Accompanying drawing is depicted as the structural representation of the embodiment that the utility model provides.Wherein Fig. 1 is its front view, and Fig. 2 is along Figure 1A-A cutaway view.1 is sieve plate among the figure, is made by rubber, and its surface is furnished with round sieve 2, and this sieve aperture is designed to the hole of certain taper from inside to outside; Like this, help the discharge of material, avoid stopping up; Outer surface at rubber sieve plate is covered with the surperficial criss-cross that is, the cross section is the steel backing 3 of arc, and this steel backing adopts cast-steel integral casting, is fixed together with a plurality of bolts 4 between steel backing and the rubber sieve plate.Steel backing is by on the skeleton that is bolted to drum sieve that is located at its limit portion.
