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 to drift along device, also relate to a kind of coal simultaneously and to drift along method, belong to coal preparation technology field.
Background technology
Coal drifts along and refers to that the density into understanding feed coal forms, namely refer to each quantity of density level product, the floating experiment of Mass Distribution, specifically refer to the density variation according to coal, make it be separated in media as well, thus understand the quality index of each density level product, determine the efficiency of separation of coal.Because gravity concentration carries out sorting with the height of the averag density of individual particle, the density composition understanding feed coal is the basic foundation of gravity concentration.At present, the conventional coal method of drifting along is: first the cylindrical net bottom bucket being placed with coal sample is put into the diameter heavy-fluid bucket larger than it, stir gently with wooden stick or net bottom bucket is gently moved up and down, after its static layering, fish for floating thing in certain direction with fishing spoon carefully, until drag for the greatest extent, finally the net bottom bucket that hypostasis is housed slowly is mentioned, tiltedly be placed on barrel rim, filter is heavy-fluid to the greatest extent, then it is put in the heavy-fluid bucket of the next density of people.Successively undertaken by density and order with same method, until coal sample is all finished, finally hypostasis is poured in dish.The major defect that above process exists has: one be coal sample amount more time, need two people's operations, a people carries the net bottom bucket that coal sample is housed and puts into heavy-fluid bucket, and a people holds wooden stick and stirs, labor intensive; Two is when mentioning the net bottom bucket dragging for floating to the greatest extent thing, and owing to there being a large amount of hypostasis to adhere at the bottom of bucket, slowly, the time is oversize for the most process of heavy-fluid filter; Three be whole process of drifting along by manually completing, the net bottom bucket that coal sample is housed need be put into one after another, propose heavy-fluid bucket, and the amount of labour is large.
Summary of the invention
The object of the present invention is to provide a kind of coal to drift along device, to increase work efficiency, reduce workload.
In addition, a kind of coal is the present invention also aims to provide to drift along method.
To achieve these goals, technical scheme of the present invention have employed a kind of coal and to drift along device, and comprise heavy-fluid bucket, flotation unit, heavy-fluid bucket is connected with flotation unit by connecting pipe.
Described flotation unit is by outer barrel and be set on bucket in outer barrel and form, and the bucket wall of described interior bucket evenly offers open-work.
Flotation unit outer barrel bottom is provided with woven hose.
The mouth of pipe place of woven hose is provided with pipe close, and pipe close is opened and closed by 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 additionally uses a kind of coal method for floating, comprise the following steps: coal sample is put into flotation unit bucket, density fluid in heavy-fluid bucket is sent into by tube connector in the outer barrel of flotation unit, density fluid enters interior bucket by open-work equally distributed on inner barrel wall face, coal sample carries out layering in interior bucket, form hypostasis and floating thing, thing will be floated and take out; Open the pipe close at woven hose mouth of pipe place, density fluid is back in heavy-fluid bucket again; By tube connector, the density fluid of next density level is transported in flotation unit, is successively undertaken by density and order, until coal sample is all finished.
Adopt method of the present invention and flotation unit, first coal sample is put into flotation unit, by pump, the density fluid in heavy-fluid bucket is transported in flotation unit, after layering, form hypostasis and floating thing, after dragging for floating to the greatest extent thing with fishing spoon, under the effect of lifting device, pipe close is raised, and density fluid flows back in corresponding heavy-fluid bucket by deadweight again, is then transported in flotation unit by the density fluid of pump by next density level.Successively undertaken by density and order with same method, until coal sample is all finished, finally with fishing spoon, hypostasis is taken out, pour in dish.Adopt device and method of the present invention, no matter coal sample amount is how many, all can complete whole floating experiment by a people, save human resources; After dragging for floating to the greatest extent thing, heavy-fluid is leached by netted barrel, and solve the heavy-fluid filter problem that process is slow to the greatest extent, operating efficiency is high; Heavy-fluid is carried by pump, then relies on deadweight to flow back to heavy-fluid bucket, and coal sample also need not move again, reduces labour intensity, improves coal and to drift along the automaticity of process, have good application value.
