Description
Technical field
The invention belongs to raw coal separation technical field, relate to a kind of raw coal three grades of separators.
Background technology
In a lot of raw coal, containing gangue, gangue content is larger, and the unit caloric value of coal is less, and quality is poorer, and this raw coal selling price containing gangue is lower.In order to improve the quality of coal, need gangue to separate from raw coal, be separated gangue carry out in two steps, one is crushed to certain fineness, two be by pulverize after duff mix with water, by coal water mixed liquid importing separator in carry out cleaning sorting.In prior art, the raw coal separation machine class of different structure, different model and size is a lot, and these separators respectively have advantage, and ubiquity sorting index is not high, ineffective shortcoming.
Summary of the invention
The present invention is directed in prior art, it is not high to there is sorting index in raw coal separation machine, ineffective problem, there is provided a kind of raw coal three grades of separators, this machine is by coal washing storehouse, water filling storehouse and discharge nozzle three part composition, coal washing position in storehouse is on front side of water filling storehouse, discharge nozzle is positioned on rear side of water filling storehouse, upper end, coal washing storehouse is dropped down out, flitch was installed in the below of upper waterline, coal washing storehouse is communicated with the lower curtate in water filling storehouse, base plate is downward-sloping, the dividing plate envisaged underneath in coal washing storehouse and water filling storehouse has water filling port, top is designed with gap, above water filling storehouse, rotating shaft is installed, one end of rotating shaft is connected with exterior power source, rotating shaft is provided with eccentric wheel, eccentric both sides are provided with connecting rod, the lower end of connecting rod is provided with water filling plate, water filling plate is positioned at the top of water filling port, at another side lower in water filling storehouse, water inlet pipe is installed, water inlet pipe is connected with high-pressure water pipe, discharge nozzle is arranged on bottom the downward-sloping base plate in water filling storehouse, the top of discharge nozzle is upwards holded up, the discharging opening of top is higher than the upper waterline in coal washing storehouse, in discharge nozzle, material scraping plate is installed.
This machine is formed by after the identical coal washing storehouse of structure, water filling storehouse and discharge nozzle three grades of combined serial, and the entrance of coal water mixture is positioned at the suitable for reading of first order coal washing storehouse, and outlet is positioned at the suitable for reading of third level coal washing storehouse.
Adopt the technical program, due in the raw coal containing gangue, the density and hardness of coal is less than gangue, and in crushing process, gangue is not easy to be broken, and coal is easily broken, and therefore after pulverizing, the particle diameter of gangue is comparatively large, and the particle diameter of coal is less, when after mixing with water containing the duff of gangue from the upper inlet in first order coal washing storehouse enter coal washing storehouse clean time, axis of rotation above water filling storehouse, water inlet pipe on rear side of water filling storehouse is washed by water in water filling storehouse, eccentric wheel above water filling storehouse in rotating shaft promotes water filling plate and moves up and down in water filling storehouse, control the gap between water filling plate and water filling storehouse sidewall, make opposing seal between water filling plate and water filling storehouse sidewall, when water filling plate moves, water under high pressure enters water filling storehouse from water inlet pipe, when water filling plate moves down, the water of water under high pressure and bottom, water filling storehouse is from water filling port press-in coal washing storehouse, the water in press-in coal washing storehouse rinses the compound of duff and gangue from bottom to top, upper strata, coal washing storehouse is floated on after duff in compound is rinsed, along with the flowing of water flows into next stage coal washing storehouse, gangue in duff due to density large, the bottom dropping to coal washing storehouse can be continued when rinsing, the bottom of base plate is slipped to from the base plate of bottom angled, blown off by the scraper plate of discharge nozzle in bottom, be transported to the top outlet of discharge nozzle, discharge by outlet.
For making the gangue in duff share thoroughly, by coal washing storehouse identical for structure, water filling storehouse and discharge nozzle three grades of combined serial, after three grades of cleaning sortings, from the duff mixing water that the outlet of final stage coal washing storehouse is discharged, the quality of duff is better.
The present invention has reasonable in design, and the isolated ratio of the gangue in duff is higher, greatly can improve the quality of duff.After being separated, duff is worth and improves, and can be used for the sintering of iron ore; Gangue is then used as the production fuel of the building materials such as wall brick, although value can decline to some extent, after balancing each other with the value-added degree of duff, the overall value of duff improves; After segmentation, the coal of different quality is more applicable in different use occasions, and price is also more reasonable, and the duff sales volume therefore after sorting is much better than the duff of not sorting.
The present invention is rational in infrastructure, and sorting and the operating efficiency of duff are higher.
