Abstract
The utility model relates to a coal slime sinking and floating machine and belongs to equipment which recovers float coal from coal slime with extremely poor floatability. The utility model mainly solves the technical problem that the traditional floatation equipment cannot recover the float coal from the coal slime with extremely poor floatability. The utility model adopt the following technical scheme: the coal slime sinking and floating machine comprises a high-pressure water tank and a valve, wherein the coal slime sinking and floating machine further comprises a plurality of transverse water pipes, a plurality of water spray nozzles and a shell which has a square upper part and a square taper lower part; the high-pressure water tank is arranged above the shell; the water spray nozzles are mounted on the transverse water pipes; the water spray nozzles and the transverse water pipes are arranged at the lower part of an inner cavity of the square shell and water spraying ports of the water spray nozzles face upwards; the high-pressure water tank is connected with the transverse water pipes through a vertical water pipe; the valve is mounted at a middle upper part of the vertical pipe; and a material discharging port is arranged at the square taper bottom of the shell. The coal slime sinking and floating machine has the following advantages: the float coal with extremely poor floatability can be produced effectively by ore-dressing and washing and various kinds of chemicals are saved.
Description
Technical field
The utility model relates to a kind of coal slime sink-float machine, and it belongs to a kind of equipment that reclaims cleaned coal from the coal slime of floatability extreme difference.
Background technology
At present, China's coal washing industry adopts flotation device or flotation column to carry out sorting according to the difference of mineral (coal slime) Surface Physical chemical property to reclaiming cleaned coal in the mine tailing (coal slime) substantially, and flotation column reclaims the cleaned coal in the better coal slime bigger effect.But the recovery to cleaned coal in the coal slime of floatability extreme difference can not utilize the difference of density and dynamics to carry out sorting, thereby has caused a large amount of losses of coal resources, has caused environmental pollution, has influenced the economic benefit of coal washing industry.
Summary of the invention
The purpose of this utility model is to solve the technical problem that can not reclaim cleaned coal from the coal slime of floatability extreme difference that existing floatation equipment exists, and a kind of coal slime sink-float machine that can obtain cleaned coal from the ature of coal coal slime of floatability extreme difference is provided.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: coal slime sink-float machine, comprise a high-pressure water tank and valve, wherein: it also comprises some horizontal water tubes, several water spouts and the housing that top is the side's of the being taper of square bottom, high-pressure water tank is located at the top of housing, water spout is contained on the horizontal water tube, water spout and horizontal water tube together are located at the water jet of the bottom of square casing inner chamber and water spout towards top, high-pressure water tank is connected with horizontal water tube by vertical water pipe, valve is contained in the middle and upper part of vertical water pipe, is provided with the material floss hole in the bottom of housing side's taper.
The square top of described housing is welded into by four block plates, and wherein two block plates are short steel plate, so that the cleaned coal overflow.
The cone angle of described housing side taper is 65 °.
Because the utility model adopted technique scheme, solved the problem that difference that existing floatation equipment can not utilize density and dynamics is carried out floatability extreme difference slime separation.Compare with background technology, the utlity model has following advantage:
1, washing goes out floatability extreme difference cleaned coal (Bed for Fine Coal that 300 orders are above) effectively, can create favorable economic benefit for coal washing industry, reaches the energy-conservation effect of gain, has controlled the pollution of environment simultaneously within the specific limits.
2, save the use (not needing to make with medicament during the coal separation of coal slime sink-float machine washing) of various medicaments, saved production cost effectively.
3, solved the problem that floatability extreme difference coal slime can not reclaim cleaned coal, and it is few to have reached unit, floor space is little, is easy to configuration, convenient management, and maintenance load is little, and personnel are few, and corresponding investment and producing cost are few, and income is bigger aspect economic effect.
4, simple in structure, easy to maintenance, energy consumption is low, and the life-span is long, can long-term safety move, and is convenient to maintenance and adjustment, and parts are wear-resisting durable, help maintenance, reduced maintenance cost.
5, adapt to the automated production needs.Operate easy to adjustly, system is flexible, has reduced the quantity that checks instrument and executing agency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As depicted in figs. 1 and 2, coal slime sink-float machine in the present embodiment, comprise a high-pressure water tank 1 and valve 2, wherein: it also comprises some horizontal water tubes 5, several water spouts 4 and the housing 6 that top is the side's of the being taper of square bottom, high-pressure water tank 1 is located at the top of housing 6, water spout 4 is contained on the horizontal water tube 5, water spout 4 and horizontal water tube 5 together are located at the water jet of the bottom of square casing 6 inner chambers and water spout 4 towards top, high-pressure water tank 1 is connected with horizontal water tube 5 by vertical water pipe 3, valve 2 is contained in the middle and upper part of vertical water pipe 3, is provided with material floss hole 7 in the bottom of housing 6 side's tapers.The square top of above-mentioned housing 6 is welded into by four block plates, and wherein two block plates are short steel plate, so that the cleaned coal overflow.The cone angle of above-mentioned housing 6 side's tapers is 65 °.
Usage quantity of the present utility model can be according to the decision of the coal slime water yield, and the use of can connecting also can in parallelly be used.
Selected principle of the present utility model is: utilize water spout correctly to regulate the flow and the pressure of water, the different coal slime of floatability extreme difference coal slime granularity and the material of other composition are sunk rapidly, reach the purpose of effective extraction cleaned coal.
The course of work of the present utility model is: before the start; fill with clear water in the housing in advance; the start back is poured into the black water that concentration is lower than 150 grams per liters from housing one; after black water injects; the coal grain that is lighter than water inclines from another of housing and overflows (being cleaned coal), and spoil that particle is big, quality is heavy and coal grain are slowly heavy to housing bottom.When injecting black water, open the valve of high-pressure water tank, and correctly regulate the flow and the pressure of water, by the water spout in the housing to the water delivery of housing top, make the cleaned coal in the black water upwards constantly overflow the acquisition cleaned coal, spoil is discharged by the material floss hole of housing bottom.
