Abstract

The utility model discloses a suspended dual-frequency vibrating screen. The suspended dual-frequency vibrating screen comprises a vibrating screen box, wherein a flexible screen plate is fixed on the upper surface of each cross beam in the screen box; a resonate rack is arranged below each flexible screen plate; a resonate beam in equal height with the resonate rack is mounted on the resonate racks between all the cross beams of the screen box respectively; fixing clips are respectively connected between the upper surfaces of the resonate beams and the bottom surfaces of the flexible screen plates; and rubber springs are uniformly distributed and fixed between the upper and the lower surfaces at the peripheries of the resonate racks and the screen box. According to the utility model, as the flexible screen plates are fixed on the cross beams of the screen box, and the screen plates in the middles of the cross beams are fixed on the resonate beams, during operation, the screen plates conduct bending motion and stretching motion while vibrating along with the screen box, so that the vibration strength is greatly increased, the screening efficiency is effectively improved, and particularly when materials with strong viscosity are screened, hole blockage is not easy.

Description

Floated double frequency vibration sieve

Technical field:

The utility model relates to screening plant, the floated double frequency vibration sieve that particularly a kind of screening efficiency is high, applied widely.

Background technology:

Existing vibratory sieve; Its sieve plate (net) all is directly to be fixed on the screen box; Sieve plate during screening (net) makes material sieve along the movement locus of setting along with screen box vibrates together, under the vibrating motor of identical horsepower drives, produces certain amplitude and certain screening efficiency.Because of not producing secondary vibration, so oscillation intensity is little, when handling tough material, stoppage phenomenon influences screening efficiency easily, improve screening efficiency, and also the power of necessary expanded motor causes energy consumption high.

Summary of the invention:

It is high, applied widely that the utility model purpose provides a kind of screening efficiency, the floated double frequency vibration sieve that energy consumption is low.

The technical scheme of the utility model is accomplished as follows; It includes a vibrating screen box; It is characterized in that: beam surface upper is fixed with a flexible sieve plate in screen box; Below flexible sieve plate, be provided with a resonance frame; On the resonance frame between each crossbeam of screen box, be separately installed with a resonant beam with height such as resonance frame grade, each is connected with fixed card respectively above the resonant beam and between the flexible sieve plate bottom surface, is fixed with rubber spring being uniformly distributed with respectively between upper surface and the screen box under the resonance frame periphery.The utility model is fixed on flexible sieve plate on the screen box crossbeam; Simultaneously the sieve plate in the middle of the crossbeam is fixed on the resonant beam; Do bending and extensional motion again when sieve plate vibrates with screen box during work, increased oscillation intensity greatly, so can effectively improve screening efficiency; Particularly to tough material screening the time, be difficult for plug-hole.

Description of drawings:

Accompanying drawing is the structural representation of the utility model.

The specific embodiment:

Describe embodiment in detail in conjunction with accompanying drawing, the utility model is that crossbeam 3 upper surfaces in a vibrating screen box 1 are fixed with a flexible sieve plate 2, and flexible sieve plate can be processed into polyurethane material.Below sieve plate, be provided with a resonance frame 6; On the resonance frame between each crossbeam of screen box, be separately installed with a resonant beam 4 with height such as crossbeam grade; Be connected with fixed card respectively between each resonant beam upper surface and the flexible sieve plate, between the upper and lower surfaces of resonance frame periphery and screen box, be uniformly distributed with respectively and be fixed with rubber spring 5.The utility model can make the local oscillation intensity of sieve plate increase by two to three times under the situation that does not increase vibrating motor horsepower, effectively improves screening efficiency, and the material scope that is suitable for screening is wide, and range of application is big.
