Abstract
The utility model belongs to a high-efficiency separator for solid mixtures, particularly relating to a vibration reverse divided type air heavy-media separator. The vibration reverse divided type air heavy-media separator is composed of an air inlet, raw materials and a heavy media inlet, floats and a heavy media outlet, sinking objects and a heavy media outlet, dust gas outlet, a multi-air chamber distributing device, and a fluidized bed. The utility model is characterized in that the fluidized bed is provided with a vibrator, the floats and the heavy media outlet and the sinking objects and the heavy media outlet are respectively provided with baffles. The utility model avoids the shortcomings of the wear of a general-purpose machine conveying type heavy-media separator, the complicated equipment, etc.
Description
The utility model is a kind of efficient cyclone of solid mixture, is specifically related to the reverse shunting air dense medium of a kind of vibration separator.
Air---the principle of dense medium separation technology is: utilize dispersion and the suspension of dense media particulate in air-flow, under optimum conditions, can form a desirable fluidized-bed layer that is similar to liquid homogeneous density, difference according to solid mixture and bed density, light thing floats on the surface, weight is sunken to the bottom, uses different means and device respectively light, heavy material to be removed from bed then, thereby finishes effective separation of solid mixture.
Technology maturation and very representational device in air----the dense media method sorting process, " adverse current tandem " fluid bed cleaning unit (Counter-Current FluidizedCascads that Beeckmans is abroad arranged, Beeckmans, J.M.and Goransson, M., CIM Builetin, 75 (839), 184 (1982)); " the reverse conveying-type of scraper plate " air dense medium fluid bed dry coal preparation device that the domestic Chen Qingru of having professor is proposed (Chen Qingru, Yang Yi, Yu Zhimin, Liu Huansheng, Li Jianming, the 5th national fluidization proceeding, 1990, P345) as shown in Figure 1:
1 is inlet, 2 medium inlets of attaching most importance to, 3 are the dusty gas outlet, and 4 is the up scraper plate of drag conveyor, and 5 is float coal and dense media outlet, 6 are the multilayer multihole distributor of weaving cotton cloth, 7 is gas diffluence room, and 8 is total air intake, and 9 is rectangle slot type air dense medium fluid bed, 10 is the descending scraper plate of drag conveyor, and 11 is hypostasis and dense media outlet.
For the light thing that will float on the surface separates with the weight that is sunken to the bottom, above-mentioned two kinds of devices have all adopted baroque, mechanical drag conveyor, thereby following tangible deficiency occurred:
(1) adding of drag conveyor all brings direct influence to the control of the even suspended state of air dense medium fluid bed and the adjusting of operating condition;
(2) the reasonably combined adjustable extent of scraper plate transporting velocity and air dense medium sorting condition has limited the production intensity of this sorting unit;
(3) mechanical wear in the equipment of scraper plate machine and the running thereof increases screening installation complex structure and cost.
The purpose of this utility model is to develop a kind of floating thing and separates the reverse shunting air dense medium of easy vibration separator with hypostasis.
Described separator is made up of raw material and dense media inlet, floating thing and dense media outlet, hypostasis and dense media outlet, ash-laden gas outlet, many air chambers distributor, air intake and fluid bed, it is characterized in that the outlet of described floating thing and dense media outlet and hypostasis and dense media is respectively equipped with plate washer, be used for regulating the fluidized-bed layer height, and make hypostasis and the dense media can be from the stable discharge of an end.Described fluid bed has vibrator, can form the air dense medium fluid bed of the oscillatory type with certain gradient.The distribution grid of described fluid bed can be the multihole distributor that many air chambers, multilayer are weaved cotton cloth.Described fluid bed can be the rectangle slot type, can carry out a plurality of parallel combinations, produces load so that increase.
Principle schematic of the present utility model is as shown in Figure 2: 1 is inlet, 2 medium inlets of attaching most importance to, 3 are the ash-laden gas outlet, 5 are floating thing and dense media outlet, and 6 is distribuor of fluidized bed, and 7 is gas diffluence room, 8 is total air intake, 9 is rectangle slot type air dense medium partition fluidized bed, and 11 is hypostasis and dense media outlet, and 12 is vibrator.
The solid mixture material adds from top, the middle part charge door 1 that is positioned at rectangle slot type partition fluidized bed 9, air sprays into through distribution grid 6, the dense media particulate disperses in air-flow and suspends, form the fluidized-bed layer of the homogeneous density of similar liquid state, less floating the formation thereon of solid of proportion floats thing in the raw material, moving right exports 5 places to floating thing and dense media and discharges, and the solid that proportion is bigger in the raw material sinks to it and forms hypostasis down and be moved to the left, to hypostasis and dense media outlet 11 discharges.Vibrator in the fluid bed plays the effect of the reverse shunting of vibration.
The advantage that the utility model " vibrates reverse shunting " is conspicuous:
1. the introducing of vibrational energy helps the fragmentation of bubble in the air dense medium fluid bed and the evenly formation of suspension density, and opereating specification is widened, and handles the intensity increase, thereby more helps the efficient separation of granulate mixture.
2. hypostasis is discharged to an end by vibration great-jump-forward ground in air dense medium fluid bed bottom, and causes the reverse convective motion of floating thing, need not machinery to carry, thereby makes equipment simple, and processing ease and cost reduce.
The utility model can be used for real processes such as ore dressing, coal separation, the processing of industrial solid waste residue, industrial residue mixture with the processing Taiyuan Chemical Fertilizer Factory is an example, processing through the utility model air dense medium separator that " vibrates reverse shunting ", cinder mixture to two kinds of thickness granularities all can be separated fully, and detailed results is listed in table 1.
Table 1: industrial cinder mixture separation results
| Cinder mixture (coke content 10-30%) | After the separation | |||
| Heavy (the Kg/m of coke ratio 3) | Heavy (the Kg/m of slag ratio 3) | Coke content % in the slag | ||
| Coarseness | 50-13mm | 1778 | 2661 | ＜5％ |
| Fine granularity | 13-3mm | 1771 | 2148 | ＜5％ |
Jiao after the separation, wherein dregginess＜5% can be used to gas making and does other fuel use; Cinder after the separation, wherein coke content all＜5% can be made ground and the building materials of paving the way.Be not difficult to find out that the utility model has obvious social, environmental benefit and economic benefit for solving cinder separation utilization and reducing problem of environmental pollution and opened up a new way.
The utility model can be widely used in the efficient separation process of multiple solid mixture, simple, the processing ease of equipment, and small investment, cost is low, floor space is little, more need not water, and very strong prospects for commercial application and huge market competition potentiality are arranged.
