For achieving the above object, the utility model can take following technical proposals:
Dry type Machine-made Sand production system described in the utility model, comprise connect successively crusher, vibrator supply mechanism, wind riddle separating device; The dust removal port of described wind riddle separating device connects the import of primary dust removing equipment, the import of the air outlet connecting fan of described primary dust removing equipment, and the outlet of described blower fan connects the blast inlet of wind riddle separating device and the import of two-stage dust removal equipment respectively; The crude product outlet of described wind riddle separating device connects the import of described crusher, the top of wind riddle separating device is provided with dust removal port and feeding mouth, side air admission mouth is provided with below described feeding mouth, the middle part of wind riddle separating device is provided with screen cloth, and the bottom of wind riddle separating device is provided with the product outlet be positioned at below described screen cloth and the crude product outlet being positioned at outlet below, screen cloth lower end; Described feeding mouth is connected with the discharge port of described vibrator supply mechanism.
The export pipeline of described blower fan is provided with flow distributor.
Described screen cloth is arranged to described crude product outlet lopsidedness.
Described primary dust removing equipment is tornado dust collector.
Described blower fan works in selection by winnowing and dedusting simultaneously.
The utility model utilizes same blower fan to complete selection by winnowing and dedusting operation, selects two-stage dust removal installation simultaneously, has following beneficial effect:
the wind riddle separating device structure used is simple, dedusting abundant, is beneficial to bolting operation, largely improves screening efficiency;
according to the feature of wind path feature and Fan Equipment, the Fans equipment that makes full use of completes selection by winnowing and gathers dust, and reduces system configuration cost;
classification dedusting, selects tornado dust collector, replaces the function of specific equipment, reduce the configuration requirement of specific equipment, thus reduce the maintenance cost in system configuration cost and later stage with general-purpose equipment part;
owing to being configured with air-flow distributor in malleation pipeline, selection by winnowing dynamics is controlled, thus the powder containing quantity in adjustment finished sand.
In sum, dry type Machine-made Sand production system of the present utility model takes full advantage of equipment complex performance, effectively reduces system energy consumption, greatly reduces equipment investment cost and later maintenance cost, is high, the environment friendly and pollution-free sand system processed of a kind of selection by winnowing efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, dry type Machine-made Sand production system described in the utility model, comprise connect successively crusher 1, vibrator supply mechanism 2, wind riddle separating device 3; The top of this wind riddle separating device 3 is provided with dust removal port 4 and feeding mouth 10, side air admission mouth 7 is provided with below feeding mouth 10, the middle part of wind riddle separating device 3 is provided with screen cloth 11, this screen cloth 11 exports 9 lopsidedness to crude product and arranges, and the bottom of wind riddle separating device 3 is provided with the product outlet 12 be positioned at below screen cloth 11 and the crude product outlet 9 being positioned at outlet below, screen cloth 11 lower end.Described feeding mouth 10 is connected with the discharge port of vibrator supply mechanism 2, and dust removal port 4 connects the import of the tornado dust collector 5 being used for primary dust removing.Meanwhile, crude product outlet 9 is connected by the import of lift technique with crusher 1, carries out secondary breaking, selection by winnowing to defective crude product.The import of the air outlet connecting fan 6 of tornado dust collector 5, the outlet of blower fan 6 connects the import of the blast inlet 7 of wind riddle separating device 3 and the fly-ash separator 8 for two-stage dust removal respectively, and arranges air-flow distributor 13 on this outlet malleation pipeline.
The crusher 1 adopted in the present embodiment is vertical shaft impact crusher.
The vibrator supply mechanism 2 adopted in the present embodiment, can make sand material vibrate at level, vertical direction, thus reach the object of even bulk cargo, be conducive to follow-up selection by winnowing.At raw material ideally, can be replaced by friction feeding device.
Adopt wind riddle separating device 3 in the present embodiment, implement selection by winnowing with malleation controllable air flow, usually set up the setting device such as bulk cargo, backgauge, thus reach better result of use.
Tornado dust collector 5 in the present embodiment are that the centrifugal force utilizing swirling eddy to produce makes grit be separated from air-flow.In systems in which, blower fan 6 produces malleation and negative pressure can be fully used.According to the requirement to finished sand size fractionated ratio and content of stone powder, by air-flow distributor 13, with the air-flow size entering fly-ash separator 8, distribution is carried out to the air-flow entering wind riddle separating device 3 and control, realize the adjustment to selection by winnowing air-flow.
During use, rubble raw material is processed into Machine-made Sand by crusher 1, delivers to vibrator supply mechanism 2 via handling equipment, enter wind riddle separating device 3.Raw material is by the free blanking of feeding mouth 10, and now blast inlet 7 place has the malleation air-flow that blower fan 6 provides, and with under the effect of sand material, by dust separation wherein, and is sent to dust removal port 4.Sand material after dedusting falls to and carry out screening operation on the vibration screen 11 of crude product outlet 9 inclination, and qualified finished sand falls below screen cloth 11, exports finished sand by product outlet 12; The underproof sand material of particle diameter falls into crude product outlet 9 above screen cloth 11, then takes back crusher 1 by handling equipment, re-starts fragmentation.
Dust laden air enters the tornado dust collector 5 for primary dust removing from the external pipeline of dust removal port 4, eddy current is formed along the flowing of its inwall, the grit generation sedimentation that particle diameter is greater than 0.005 ~ 0.01 millimeter, stone flour collecting bin is entered from tornado dust collector 5 bottom, the negative pressure that residue is provided by blower fan 6 containing micro mist gas is from tornado dust collector 5 top sucking-off, two-way is divided into by air-flow distributor 13: a road returns blast inlet 7 recycle of wind riddle separating device 3 after blower fan 6, additional air is sent into and is used in the fly-ash separator 8 of two-stage dust removal by another road, air is entered after further purification, the stone flour that fly-ash separator 8 collective low obtains through sedimentation.
