Abstract
The invention relates to a coal floating and sinking device and method, wherein the coal floating and sinking device comprises a heavy liquid barrel and a flotation device; the heavy liquid barrel is communicated with the flotation device through a connecting pipeline. By using the device and the method provided by the invention, an entire floating and sinking experiment can be finished by a person in spite of the amount of a coal sample, so that the human resources are saved; after all floats are fished, heavy liquid is filtered by a netlike drum wall, so that the problem of slow filter process of the heavy liquid is solved and the working efficiency is high; the heavy liquid is conveyed by a pump and flows back into the heavy liquid barrel by means of dead weight of the heavy liquid, and the coal sample is not required to be moved yet, so that the labor intensity is reduced, the degree of automation during coal floating and sinking is improved; and the device and the method have extremely high promotion and application values.
Description
Technical field
The present invention relates to a kind of coal device that drifts along, also relate to a kind of coal method of drifting along simultaneously, belong to the coal preparation technology field.
Background technology
Coal drifts along and is meant to understanding the density composition of feed coal; Just refer to the quantity of each density level product, the floating experiment of mass distribution, specifically be meant density variation, in medium, make its separation according to coal; Thereby understand the quality index of each density level product, confirm the efficiency of separation of coal.Carry out sorting because gravity concentration is the height with the averag density of individual particle, it is the basic foundation of gravity concentration that the density of understanding feed coal is formed.At present, the coal method of drifting along commonly used is: the cylindrical net bottom bucket that will be placed with coal sample is earlier put into diameter than its big heavy-fluid bucket, stirs gently or the net bottom bucket is gently moved up and down with wooden stick; After treating its static layering, fish for floating thing with fishing spoon by certain orientation carefully, till dragging for to the greatest extent; Slowly mention the net bottom bucket that hypostasis is housed at last; Tiltedly be placed on the barrel rim, filter is heavy-fluid to the greatest extent, puts it in the heavy-fluid bucket of the next density of people again.Use with quadrat method and undertaken by density and order one by one, till coal sample is all finished, at last hypostasis is poured in the dish.The major defect that above process exists has: the one, and the coal sample amount needs two people operation more for a long time, and a people is carrying the net bottom bucket that coal sample is housed and is putting into the heavy-fluid bucket, and a people holds wooden stick and stirs, labor intensive; The 2nd, when mentioning the net bottom bucket that drags for floating to the greatest extent thing, because the bucket end has a large amount of hypostasis to adhere to, process is very slow to the greatest extent in the heavy-fluid filter, and the time is oversize; The 3rd, the whole process of drifting along is accomplished by manual work, and the net bottom bucket that coal sample is housed need be put into one after another, propose the heavy-fluid bucket, and the amount of labour is big.
Summary of the invention
The object of the present invention is to provide a kind of coal device that drifts along,, reduce workload to increase work efficiency.
In addition, the present invention also aims to provide a kind of coal method of drifting along.
To achieve these goals, technical scheme of the present invention has adopted a kind of coal device that drifts along, and comprises the heavy-fluid bucket, flotation unit, and the heavy-fluid bucket is connected with flotation unit through connecting pipeline.
Described flotation unit is made up of outer bucket and the interior bucket that is set in the outer bucket, evenly offers open-work on barrel wall of bucket in described.
Be provided with woven hose at the flotation unit outer barrel bottom.
The mouth of pipe place of woven hose is provided with pipe close, and pipe close opens and closes through lifting device.
The position, bottom of described flotation unit is higher than heavy-fluid bucket position.
Described tube connector is provided with the pump housing.
Technical scheme of the present invention has also adopted a kind of coal method for floating; May further comprise the steps: the bucket of the coal sample being put into flotation unit; Density fluid in the heavy-fluid bucket is sent into through tube connector in the outer bucket of flotation unit, and density fluid is through bucket in equally distributed open-work gets on the inner barrel wall face, and the coal sample carries out layering in interior bucket; Form hypostasis and floating thing, will float thing and take out; Open the pipe close at woven hose mouth of pipe place, density fluid is back in the heavy-fluid bucket again; Be transported in the flotation unit through the density fluid of tube connector, undertaken by density and order one by one, till coal sample is all finished next density level.
Adopt method of the present invention and flotation unit, earlier coal sample is put into flotation unit, the density fluid in the heavy-fluid bucket is transported in the flotation unit by pump; After the layering, form hypostasis and floating thing, drag for floating to the greatest extent thing with fishing spoon after; Under the effect of lifting device; Pipe close is raised, and density fluid flows back in the corresponding heavy-fluid bucket through deadweight once more, is transported in the flotation unit by the density fluid of pump with next density level then.Use with quadrat method and undertaken by density and order one by one, till coal sample is all finished, with fishing spoon hypostasis is taken out at last, pour in the dish.Adopt device and method of the present invention, no matter the coal sample amount what, all can accomplish whole floating experiment by a people, practiced thrift human resources; After dragging for floating to the greatest extent thing, heavy-fluid is leached by netted barrel, has solved the heavy-fluid filter slow problem of process to the greatest extent, high efficiency; Heavy-fluid is carried by pump, relies on deadweight to flow back to the heavy-fluid bucket again, coal sample also needn't move again, has reduced labour intensity, has improved the drift along automaticity of process of coal, has the excellent popularization using value.
