Description
Technical field
The utility model relates to and a kind ofly dry method is rolled mulling that sand processed formed by the dry method sand heavy die block formula vibration screening device entering point sifting sort regardless of specification of required sand, belongs to dry method sand production line sand screening separator manufacture field.
Background technology
CN103433108A, title " a kind of dry method sand equipment and technics ", comprise jaw crusher, impact crusher, the first classifying screen, dry method sand machine, the second classifying screen and concentrated dust collecting system, production process route is, the building stones in building stones storehouse are sent into jaw crusher equably by batcher and are carried out first time coarse crushing, material after fragmentation is transported in impact crusher and carries out second time fine crushing, material after fragmentation enters the first classifying screen and carries out classification, the sandstone being less than 40mm is delivered to dry method sand machine by conveyer and is carried out pulverizing sand processed, the rubble being greater than 40mm returns impact crusher, the sand material entering dry method sand machine is transported to the second classifying screen and carries out classification after the pulverizing of dry method sand machine, the sand being less than 3mm is directly admitted in finished product sand storage, the building stones being greater than 3mm return to dry method sand machine and pulverize, produce each airborne dust point by concentrated dust collecting system concentrated dust collecting, stone flour after collection is transported to stone flour storage and deposits.Its weak point: one is the screening that cannot realize carse, medium and small three kinds of sand.
Utility model content
Purpose of design: avoid the weak point in background technology, designs and a kind ofly dry method is rolled mulling that sand processed the formed dry method sand heavy die block formula vibration screening device entering point sifting sort regardless of specification by required sand.
Design: in order to realize above-mentioned purpose of design.1, the design of modular vibration screening device is one of technical characteristic of the present utility model.The object of such design is: due to modular vibration screening device in structural design by fixed linear vibrating screen, upper portable linear vibrating screen and roll off the production line straight vibratory sieve and upper linear vibrating screen guide rail and lower linear vibrating screen guide rail are formed, no matter be fixed linear vibrating screen, upper portable linear vibrating screen and the straight vibratory sieve that rolls off the production line, the weight of its each linear vibrating screen reaches 2-5 ton, in its vibratory sieve, the service life of the screening part of screen cloth only only has just must change the service life of a few hours in dry method sand production line, if be not designed to Modular moving structure, the replacing of screen cloth cannot be completed, secondly, because the raw material in the husky production line of this dry method system are after conical sand making crusher machine, enter the semi-finished product of vibratory sieve except steaming again and expecting that granularity is larger, for the grains of sand and the dust of less than 4.75, the amplitude advantage of existing fixed linear vibrating screen just cannot play, therefore the application is on the basis of existing fixing linear vibrating screen, fixing linear vibrating screen is designed to two layers of mesh structure by three layers of mesh structure, and on the basis of two layers of mesh structure, two-layer linear module sieve is added in the below of bottom screen, this two-layer linear module vibratory sieve can sieve out the sand grains of two kinds of different size scopes, because screen cloth unit order number increases, the diameter of screen cloth is also just thinner, often want damaged, this two-layer linear module vibratory sieve adopts track to release by the application for this reason, the structure resetted can change screen cloth easily, and screen cloth being prepared in advance according to modular structure one fritter one fritter, release outside when linear vibrating screen and just directly change portion's (screen cloth or module) damaged in screen cloth, not only change conveniently, speed is fast, and change laborsaving, cost-saving, reduce the wasting of resources, three is that the screen cloth in fixed linear vibrating screen has been designed to two layers by three layers by the application, not only makes the space of upper strata screen cloth and lower screen increase to more than 80cm, and solves the difficult difficult problem of linear vibration screen net replacing for a long time.2, the screen cloth of linear vibrating screen is the design of sandwich module screen cloth, is technical characteristic two of the present utility model.The object of such design is: because sandwich module screen cloth is by upper strata punishment in advance orifice plate, intermediate module screen cloth, lower floor's punishment in advance orifice plate is formed, namely this sandwich module screen cloth takes upper and lower two-layer macropore and crosses flitch or the wear-resisting punishment in advance framework of macropore, middle clamping is shaked out and is needed the standard screen cloth of order number, and be provided with a screen cloth group containing the clear chamber function of rubber hoodle in lower floor, because upper strata punishment in advance orifice plate is that rigidity crosses flitch or wear-resisting nonmetal punishment in advance plate material makes, it can not only hold by sieve sand material falling impacts power, and the impulsive force of sand material to screen cloth can be sieved by slowly-releasing widely, greatly extend the service life of screen cloth, secondly, when screen cloth is damaged, because screen cloth is module type screen mesh in structural design, thus can either quick-replaceable, again reduce screen cloth consuming cost.
Technical scheme: a kind of dry method sand production line special module formula vibration screening device, is made up of fixed linear vibrating screen, upper portable linear vibrating screen and lower mobile linear vibrating screen and upper linear vibrating screen guide rail and lower linear vibrating screen guide rail; Be provided with linear vibrating screen guide rail and lower linear vibrating screen guide rail below fixed linear vibrating screen successively, upper portable linear vibrating screen and the straight vibratory sieve of downward moving line lay respectively on linear vibrating screen guide rail and lower linear vibrating screen guide rail.
The utility model is compared with background technology, one is the design of modular vibration screening device, both solved existing fixing linear vibration screen net damage change difficult, time-consuming, take a lot of work, defect that screen cloth is all changed, the sand material that different size model turns can be sieved out again according to GB, not only meet the grating requirement that general building trade meets strong concrete and mortar especially, also meet the needs of chemical industry by husky aspect; Two is designs of many dynamic formulas linear vibrating screen, the manufacture of large-scale vibrating screen is not only made to be achieved, and achieve fixing linear vibrating screen and multilayer and move reducing of spacing between linear vibrating screen, not only to be conducive in sand material screening process dust to reclaim, and achieve quick release when portable linear vibration screen net is changed, operating personnel stand, fast, conveniently, the object of laborsaving replacing.
