Abstract
The utility model discloses a kind of dynamic sieve aperture sieve nest preventing material blocking, it comprises quiet sieve nest and is located at the dynamic sieve nest below quiet sieve nest, quiet sieve nest is provided with several quiet sieve apertures, dynamic sieve nest comprises reciprocating screen frame (unit) and is arranged at the dynamic grating on screen frame (unit), the upper end of dynamic grating is upwards interted in sieve aperture, and the side of reciprocating dynamic grating and quiet sieve aperture forms the dynamic sieve aperture of Variable.The utility model is provided with quiet sieve nest and dynamic sieve nest, constitute quiet sieve aperture and dynamic sieve aperture, during work, dynamic sieve nest produces reciprocal rectilinear motion, so namely the dynamic sieve aperture of back and forth change is formed, because stimulating the menstrual flow of dynamic grating is real-time change, so material easily falls in the gap repeatedly changed, not easily produce blocking, screening effect and screening efficiency can significantly improve.And the utility model overall structure is fairly simple, easily makes enforcement, operate more convenient, can good economic benefit be produced.
Description
Technical field
The utility model relates to the equipment used in a kind of material processing procedure, especially a kind of sieve nest that effectively can prevent material blocking, is applied particularly in the warehouse of material, transport, in feed, screening, shattering process.
Background technology
At the warehouse of material, transport, feed, screening, during fragmentation waits industrial material to produce, inevitably have critical particle, moisture, viscous materials etc. cause adverse effect to the links in process system, typical is exactly because viscosity is large, moisture causes greatly the material channel of process system (comprising sieve aperture) blocked, and the efficiency of equipment and system is declined, fault rate increases, even paralyse out of service, need a large amount of labor cleaning's work and service work, this does not conform to the requirement of large-scale automation and intelligentification production line, cause huge economic loss simultaneously.
At present, when material flows through its passage, particularly at bottleneck position, undergauge position, to there is the phenomenon of blocking in position of changing direction more serious, passage latus rectum (comprising square) is changeless (hereinafter referred to as constant latus rectum) at fixed position, rigid structural member mostly, when particle with stimulate the menstrual flow adjoining dimensions time (such particle claims critical particle), out-of-shape due to particle can cause to be stuck in passage and result in blockage, even if two or three granules also can squeeze due to bridging effect and result in blockage in passage sometimes.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of easy to operate, structure is simple, anti-material blocking is effective dynamic sieve aperture sieve nest.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of dynamic sieve aperture sieve nest preventing material blocking, its key technology is: described sieve nest comprises quiet sieve nest and is located at the dynamic sieve nest below quiet sieve nest, described quiet sieve nest is provided with side by side several quiet sieve apertures, described dynamic sieve nest comprises reciprocating screen frame (unit) and is arranged at the dynamic grating on screen frame (unit), the upper end of described dynamic grating is upwards interted in described sieve aperture, and the side of reciprocating described dynamic grating and quiet sieve aperture forms the dynamic sieve aperture of Variable.
Preferably, described dynamic grating bilateral reciprocation in the horizontal plane.
As another kind of preferred version, described quiet sieve aperture is the sieve aperture of bar shaped, and this quiet sieve aperture is up-small and down-big.Described dynamic grating top is provided with sieve bar, and described dynamic grating pumps.
Preferably, the dynamic grating tile vertically of many rows is arranged on screen frame (unit), the spacing between the dynamic grating of adjacent two row and the adjacent two quiet sieve aperture pitch match of quiet sieve nest.
Preferably, described screen frame (unit) is driven by drive unit, and this drive unit comprises motor, by the eccentric shaft of this driven by motor or cam mechanism, also can be that other can form reciprocating mechanism.
The beneficial effect adopting technique scheme to produce is:
The utility model is provided with quiet sieve nest and dynamic sieve nest, quiet sieve aperture and dynamic sieve aperture is constituted by structural design, during work, dynamic sieve nest produces reciprocal rectilinear motion, and this reciprocating motion is for pumping or bilateral reciprocation as required, so namely forms the dynamic sieve aperture of back and forth change, because stimulating the menstrual flow of dynamic grating is real-time change, so material easily falls in the gap repeatedly changed, not easily produce blocking, screening effect and screening efficiency can significantly improve.And the utility model overall structure is fairly simple, easily makes enforcement, operate more convenient, can good economic benefit be produced.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1
See accompanying drawing 1, the dynamic sieve nest that the present embodiment comprises quiet sieve nest 1 and is located at below quiet sieve nest 1, described quiet sieve nest 1 is provided with side by side several quiet sieve apertures 2, the dynamic grating 3 that described dynamic sieve nest comprises reciprocating screen frame (unit) 4 and is arranged on screen frame (unit), the upper end of described dynamic grating 3 is upwards interted in described quiet sieve aperture, and the side of reciprocating described dynamic grating and quiet sieve aperture forms the dynamic sieve aperture of Variable.The latus rectum of this quiet sieve aperture 2 is in the same size up and down,
Described dynamic grating bilateral reciprocation in the horizontal plane, side by side and be parallelly connected to above screen frame (unit) 4, described dynamic grating 3 is vertically installed on described screen frame (unit) 4 the dynamic grating 3 of many rows, and the spacing between the dynamic grating 3 of adjacent two row are equal.Described screen frame (unit) 4 is driven by drive unit, this drive unit can adopt existing energy to produce reciprocating device, structure as this drive unit can be: it comprises motor, by the eccentric shaft of this driven by motor and the pull bar (not shown) be located between screen frame (unit) 4 and eccentric shaft, screen frame (unit) 4 can be made like this to produce linear reciprocating motion.
Embodiment 2
Participate in accompanying drawing 2 and accompanying drawing 3, it is substantially identical with above-described embodiment 1, unlike: the aperture of this quiet sieve aperture 3 is up-small and down-big, described dynamic grating 3 is provided with sieve bar 5, this sieve bar 5 is vertical with dynamic grating 3 to be arranged, and and plane-parallel, this embodiment moves grating 3 for up and down reciprocatingly rectilinear motion.
Sieve aperture is up-small and down-big, and constantly changes, and for ensureing the granularity of material above it, being less than dynamic sieve aperture material and falling, because dynamic sieve aperture is reducing, when material falls, dynamic sieve aperture latus rectum becomes large, so can not block, be stuck in and sieve the material sewed on and eject along with moving up and down of dynamic grating, can not blocking.
The utility model wide adaptability, at screening operation, sieve aperture can utilize this method to make " dynamic sieve aperture ", prevents sieve pore blockade, improves screening efficiency.In feed operation, can utilize this method that feeder channel is designed to alternation latus rectum, prevent blocking.At material silo, in the industrial design of stream pipe, hopper, also can use this method, be alternation latus rectum mechanism by channels designs, prevents blocking.This method can also be applied in other to relate in the technology and equipment of material process.
