Description

Closed self-cleaning screen cloth vibratory sieve

Technical field

The utility model belongs to Supplying Sieving Mechanism, especially relates to a kind of screen cloth vibratory sieve.

Background technology

The vibratory sieve that has the single-deck screen wire side is mostly adopted in the screening of existing granule materials, and the screen cloth face will bear passing through of whole screening amounts, in use has three kinds of defectives:

Defective one: because vibratory sieve is an open type, the airborne dust that material produces in screening process is unavoidable, and this directly has influence on environment and operating personnel's health.

Defective two: because vibratory sieve is an individual layer grating wire side, in actual screening process, critical particle jam that size with the grating mesh is more or less the same is often arranged in the grating mesh, again when being sized the big bed thickness of inventory, the critical particle of jam in mesh pushed down by the material of big quality, i.e. the upwards exciting force that is subjected to more than or equal to it of the external pressure that is subjected to of the critical particle of jam, probability that its is not just shaken out, because it has occupied sieve aperture, often caused the unclean phenomenon of sieve.

Defective three: all particles greater than partition size in the logical sieve amount are leached because the individual layer grating mesh of vibratory sieve should be finished, again all powder less than partition size are sieved, obviously, all contact wears all occur on the grating of forming screen cloth.May wear to a certain degree and work as grating, whole grating net just lost efficacy and cancelled, and had influenced the service life of vibratory sieve, had increased maintenance cost.

Summary of the invention

The purpose of this utility model provides a kind of closed self-cleaning screen cloth vibratory sieve, can improve the screening efficiency of granule materials effectively, prolongs the service life of vibratory sieve, reduces and pollutes and the maintenance of equipment amount, reduces production costs.

The purpose of this utility model is achieved like this: a kind of closed self-cleaning screen cloth vibratory sieve, comprise body, support, vibrating motor, ash hole and discharging opening, body is installed on the column of support through the rubber damping spring, vibrating motor is installed in two outsides, front and back of body, the upper end feeding mouth of body is connected with the charging chute, side is offered discharging opening in the lower-left of body, offer ash hole is connected with the ash discharge chute in the bottom of body, it is characterized in that: in the inner chamber of the body of this closed self-cleaning screen cloth vibratory sieve, each layer self-cleaning screen cloth is installed successively from top to bottom, this each layer self-cleaning screen cloth all is the low oblique setting in a right high left side, and the right section of the self-cleaning screen cloth on each upper strata and the self-cleaning screen cloth of each lower floor is all folded up and down accordingly in twos to hide, this each layer self-cleaning screen cloth is all mainly by grating, roof beam structure and side plate are formed, its grating is the many elastic metallic rods that be arranged in parallel by the setting spacing, its right-hand member is perpendicular to roof beam structure and be fixed on the roof beam structure, and left end is free state; Each layer roof beam structure is arranged in parallel by the beam distance of setting and the inclination angle of setting, and with the rear and front end of each layer roof beam structure respectively correspondence be fixed on before and after each on side plate, side plate is connected with the front and back sidewall of the body inner chamber of this vibratory sieve before and after each, and adjacent grating diameter difference or length difference; The screen cloth face of each layer self-cleaning screen cloth, its sieve aperture successively decreases from large to small, enter on the upper strata self-cleaning screen cloth of this vibratory sieve by the feeding mouth of body when material after, because the upper sieve mesh sieves rapidly thoroughly much larger than partition size, larger particles is filtered away, after saturating sieve material is fallen on the second layer screen cloth face, press mesh and set, make greater than about partition size 2.4--3.6 times above particle and filtered away; Saturating sieve material is fallen again on the 3rd layer of screen cloth face, presses mesh and sets, and makes greater than about partition size 1.2--1.6 times particle and is filtered away; After the material of the saturating sieve of such three-layer network face is fallen on the 4th layer of screen cloth face, oneself is few for its amount, forms the thin layer screening, will leach greater than the particle of partition size, all are completely discharged by discharging opening greater than the particle of partition size, and are discharged by ash hole less than the powder of partition size; By of the screening of sieve material through the multi-deck screen wire side, make every layer of screen cloth face only bear the part of screening inventory, the screen cloth face of especially last aspect reaches that the screening amount is little, the effect of fine screen, make that prolonged the service life of screen cloth widely, and reach the purpose of sieving only.In addition; be positioned on the body of this vibratory sieve the screening chamber formed by each layer self-cleaning screen cloth above with bolted dust cover is installed; and the perforate correspondence is installed dust flue on this dust cover; the external bulk cement storage tank of this dust flue; simultaneously; the rubber sealing boot I is installed between the feeding mouth above charging chute and this vibratory sieve body; the rubber sealing boot II is installed between the ash inlet tube of dust flue and bulk cement storage tank; the rubber sealing boot III is installed between discharging opening on the body and discharging chute; the rubber sealing boot IV is installed between ash hole on the body and ash discharge chute; so just formed the material screening passage of sealing; reduce environmental pollution effectively; the cleaning of workplace and operating personnel's health have been protected; accomplish the cleaning screening, this rubber sealing boot I; the rubber sealing boot II; rubber sealing boot III and rubber sealing boot IV all can be the organ type sealing shroud.

The closed self-cleaning screen cloth vibratory sieve that the utility model proposes, rational in infrastructure, use reliably, the screening efficiency height of granule materials, the long service life of vibratory sieve has reduced pollution and maintenance of equipment amount, has reduced production cost.

Now in conjunction with the accompanying drawings and embodiments the closed self-cleaning screen cloth vibratory sieve that the utility model proposed is further described.
