Abstract

The utility model discloses a vibration sieve protecting sieve nets against abrasion. The vibration sieve protecting the sieve nets against abrasion comprises a sieve box and a sieving layer located in the sieve box. The sieving layer is composed of the three sieve nets which are in contact in sequence. The upper-layer sieve net and the bottom-layer sieve net are metal sieve nets and the middle sieve net is a plastic sieve net. The number of meshes of the middle-layer plastic sieve net is between that of meshes of the upper-layer sieve net and that of meshes of the bottom-layer sieve net. The middle-layer plastic sieve net is arranged between the two metal sieve nets so as to prevent the two metal sieve nets against abrasion, and the service life of the sieve nets is prolonged.

Description

A kind of vibratory sieve that prevents screen cloth wearing and tearing

Technical field

The utility model relates to a kind of separator, particularly a kind of vibratory sieve that prevents screen cloth wearing and tearing.

Background technology

Vibratory sieve mainly comprises motor, screen box, vibrator, resiliency supported etc., motor through V-belt or shaft coupling make vibrator eccentric block produce High Rotation Speed, the eccentric block of running produces centrifugal force, excite screen box to produce the motion of certain amplitude, on-the-sieve material is subject to the momentum that screen box passes to and produces continuous sling movement on the compass screen surface tilting, in the process that material and compass screen surface meet, make the particle that is less than sieve aperture thoroughly sieve, thereby realize classification.Existing screen cloth is double-layer structure, and wherein bottom screen cloth plays a supportive role, and upper strata screen cloth plays sieving actoion, and two-layer screen cloth is generally metal material, and during screening, the continuous friction between two-layer screen cloth can cause screen cloth wearing and tearing, affects screening effect.

Summary of the invention

In view of this, the utility model provides a kind of vibratory sieve that prevents screen cloth wearing and tearing, by plastic mesh in the middle of arranging in the middle of two layer screen web frame, thereby avoids screen cloth wearing and tearing.

The utility model solves the problems of the technologies described above by following technological means:

A kind of vibratory sieve that prevents screen cloth wearing and tearing of the present utility model, comprise screen box and the screening layered that is positioned at screen box inside, described screening layered is comprised of three layers of screen cloth that stack gradually, wherein upper strata screen cloth and bottom screen cloth are metallic sieve, intermediate layer screen cloth is plastic mesh, and intermediate layer sieve number is between upper strata screen cloth and bottom screen cloth.

Further, described intermediate layer screen cloth is detachable.

Further, described upper strata screen cloth is detachable.

Further, described bottom screen cloth is detachable.

Further, described screening layered is from top to bottom two or more in screen box inside.

The beneficial effects of the utility model: a kind of vibratory sieve that prevents screen cloth wearing and tearing of the present utility model, comprise screen box and the screening layered that is positioned at screen box inside, described screening layered is comprised of three layers of screen cloth that stack gradually, wherein upper strata screen cloth and bottom screen cloth are metallic sieve, intermediate layer screen cloth is plastic mesh, intermediate layer plastic screen mesh number is between upper strata screen cloth and bottom screen cloth, intermediate plastic layer screen cloth is set between double layer of metal screen cloth and can avoids the wearing and tearing between double layer of metal screen cloth, improve screen life-span.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 1 is perspective view of the present utility model;

Fig. 2 is the structural representation of screening layered in the utility model.

The specific embodiment

Below with reference to accompanying drawing, the utility model is elaborated, as shown in the figure: a kind of vibratory sieve that prevents screen cloth wearing and tearing of the present utility model, comprise screen box 1 and the screening layered 2 that is positioned at screen box inside, described screening layered 2 is comprised of three layers of screen cloth that stack gradually, wherein upper strata screen cloth 2a and bottom screen cloth 2b are metallic sieve, intermediate layer screen cloth 2c is plastic mesh, intermediate layer screen cloth 2c order number is between upper strata screen cloth 2a and bottom screen cloth 2b, intermediate plastic layer screen cloth is set between double layer of metal screen cloth and can avoids the wearing and tearing between double layer of metal screen cloth, improve screen life-span.

As shown in Figure 2, the inner bilateral symmetry of described screen box is furnished with channel-section steel 3, and three layers of screen cloth of screening layered 2 insert in both sides channel-section steel 3, thereby realize for convenience detach.

As the further improvement of technique scheme, described screening layered 2 is from top to bottom two or more in screen box 1 inside, can realize the screening of material multilayer.

Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of invention technical scheme, it all should be encompassed in the middle of the claim scope of invention.
