Above-mentioned background technology homogeneous is the generation that had not both solved the screen cloth covibration, does not also solve the phenomenon that building stones stop up sieve screen apertures; The 2nd, both do not solved the health harm of dust to the operative employee, do not solve of the pollution problem of powder method to environment yet; The 3rd, both there be not the recycling of realization to tailings material, do not realize the multipass sort and the making of building stones yet; The 4th, both can't produce in the rainy day, guarantee the drying of building stones again, working condition is subjected to the restriction of weather, can't realize round-the-clock open-air production at all.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of building stones of sorting effectively, again effectively the carse, medium and small sand of sorting and effectively sand control stop up screen cloth dry method grind special-purpose vibratory sieve mechanism and the anti-blockage method of frequently becoming of sand dedusting complete set of equipments.
Design: in order to realize above-mentioned purpose of design.1, the 3rd layer of screen cloth face top is provided with the design of blowing device, is one of technical characterictic of the present invention.The purpose of doing like this is: no matter be dry type system sand, or wet type system sand, its screen cloth is easily stopped up by sandstone, cause system sand inefficiency, be the bottleneck of restriction system sand, the application is provided with blowing device on the screen cloth face, not only can avoid the obstruction of sandstone to screen cloth by the high pressure air blowing mouth all the time, and high pressure air blowing has the sieve of interests sandstone to leak, and improved the efficient of system sand effectively.2, the screen cloth face is provided with the design of a plurality of bounders, is two of technical characterictic of the present invention.The purpose of doing like this is: because bounder is by impacting ring, impact ball and impact handle and constitute, impact ring and impact between the ball and connect by impacting handle, impacting ring is enclosed within on the airduct by the activity orientation cover, because of when vibration screening mechanism vibrates, this bounder can be in certain angle bob, impact screen cloth, the vibration frequency of screen cloth is changed, the change of this frequency, not only can avoid the generation of covibration in the screen cloth vibration processes effectively, improve the service life of screen cloth, and the change of this frequency, can avoid building stones to stop up screen cloth, improved the filter efficiency of screen cloth.3, the many exhaust ducts in the described blowing device are divided into 2 groups or 2 groups of above designs, are four of technical characterictics of the present invention.The purpose of doing like this is: because the quantity of every group of airduct is more than 2 or 2, every group of airduct air inlet communicates and controls it by by-pass valve control and whether dry, therefore control the ventilation time of every group of airduct by program timer, can realize that many exhaust ducts undulate dries successively or intersect blowing, thereby make the variable direction that blows on the screen cloth face, reach the purpose that prevents that screen cloth from stopping up.4, water smoke is pressed the design of dust hood, is five of technical characterictic of the present invention.The purpose of doing like this is: because water smoke is pressed the water smoke cover that waterfog head produced in the dust hood, most dust that conical sand making machine, vibrating mechanism can be produced cover, it can't be flown upward, its travel fatigue of missing then by dust shield and negative pressure sucking air pipe by the deduster dedusting, not only eliminated the pollution of dust to environment, and reduced the power consumption of deduster widely, reached purpose of energy saving, the more important thing is, the application can produce under round-the-clock weather conditions incessantly continuously.5, the application utilizes in the building stones shattering process, and broken building stones are to the evaporation to moisture content of broken building stones produced in the absorption of moisture content and the shattering process heat, and make wet feed system sand, obtain the design of siccative sand, be five of technical characterictic of the present invention.The purpose of doing like this is: the conical sand making machine that the application adopted is in the shattering process of building stones, when its building stones become fritter by bulk crushing, the face that is destroyed is dry face, the part moisture content that this dry face can be produced the water smoke cover absorbs, building stones are in the process of fragmentation simultaneously, because the mutual fierce bump between building stones and the building stones, the water evaporates that the heat that extruding is produced can be produced the water smoke cover, make the building stones that destroy be in the low dry status of water content, in process through the vibration screening mechanism screening, its building stones or sand be collision mutually under the effect of vibratory sieve, make made building stones, sand is further dry, in the time of in sand falls into the discharging dust shield, the band pressure wind that is blown out owing to the annular malleation blowing device (a plurality of malleation blowing mouths on the ring pipe) that is arranged in discharging dust shield below not only can blow afloat the dust of made sand and by the dust sucting pipeline that is positioned at discharging dust shield top dust be siphoned away, by the deduster dedusting, and make made sand further dry by wind, totally, thus the drying of obtaining, clean sand.
Technical scheme 1: dry method is ground the special-purpose vibratory sieve mechanism that frequently becomes of sand dedusting complete set of equipments, its involving vibrations sorting mechanism, vibratory sieve in the described vibration screening mechanism is made of three layers of screen cloth, be between three layers of screen cloth that distance distributes up and down and the aperture of three layers of screen cloth has nothing in common with each other, diminish successively from top to bottom, described the 3rd layer of screen cloth face top is provided with blowing device, and the airduct of blowing device is provided with a plurality of bounders.
Technical scheme 2: dry method is ground the special-purpose anti-blockage method that becomes vibratory sieve mechanism frequently of sand dedusting complete set of equipments, its involving vibrations screen(ing) machine structure, the 3rd layer of screen cloth in the vibratory sieve mechanism leaks down to be sand, sand is in the process of screening, be positioned at bounder spring up and down under the effect of vibration screening mechanism of screen cloth top, impact screen cloth, the frequency of screen cloth is changed, reach and avoid building stones to stop up screen cloth, its sand that sifts out leaks sand cover and conveying mechanism to the windrow storehouse by dust suction, and the malleation blowing device in the discharging dust shield blows afloat the dust in the sand once more and sucks dedusting in the deduster by dust excluding hood and dust sucting pipeline.
The present invention compares with background technology, and the one, both can make required classification stone, can make required classification sand again; The 2nd, can either prevent that building stones from stopping up the purpose of screen cloth, the service life that can improve screen cloth again effectively by changing the mode of screen cloth frequency, reaching; The 3rd, can guarantee the healthy of operative employee, can avoid contaminated environment again; The 4th, dedusting effectively can reduce the power consumption of deduster again significantly; The 5th, can be used for the processing of stone ore material, can be used for the recovery processing of tailings material again; The 6th, can be used for the processing of siccative, can be used for the processing of wet feed again, be not subjected to the restriction of environment, weather, material; The 7th, processing stone materials is utilized fully, avoided the generation of waste water again; The 8th, be not subjected to the restriction of place, weather, not only can under round-the-clock meteorological condition, produce anhydrous clean sand, and reach purpose pollution-free, zero-emission.
