Description
Technical field
The present invention relates to a kind of coal slime flotation size mixing equipment, particularly relate to a kind of stepped surface upgrading paste mixer based on energy adaptation.
Background technology
Coal is the basic energy resource of world's important energy source, Ye Shi China.While coal supports China's rapid economic development, as non-renewable resources, the reserves of coal constantly reduce, and the high-efficiency cleaning of coal resources utilizes significant.Along with the raising of mining mechanization degree, the coal amount in feed coal is along with increase, and efficient separation and the crucial focus be recycled in order to enterprise's upgrading synergy of Bed for Fine Coal are also the important embodiments of coal resources efficiency utilization simultaneously.Flotation technology is as the most effective fine coal slime separation method, and flotation operation becomes more and more important.And size mixing as the first step operation of flotation operation, will directly affect the separation index of flotation.
An important function of sizing mixing enables collecting agent be adsorbed onto object ore particle surface exactly, improves mineral floatability and flotation speed.But in the process of sizing mixing, fine beans is because its granularity is little, specific area is large, competitive Adsorption can be formed with Coarse Coal, thus cause adsorbing in floatation process, with occurring fine beans poor selectivity a large amount of medicament and low grey Coarse Coal is not adsorbed onto collecting agent and is lost in tail coal.There is this problem, different closely related with the energy requirement of sizing mixing of fine beans and Coarse Coal.
Existing size mixing equipment is all the equipment of the homogeneous input of energy.Energy input is high, and the paste mixer that shear strength is large can improve microfine coal yield, but result also in the loss of Coarse Coal simultaneously, and floatation clean coal productive rate declines; Energy input is low, and the size mixing equipment that shear strength is little can ensure the recovery of Coarse Coal, but the weak effect of sizing mixing to fine beans, causes that floatation clean coal ash content is high, productive rate is low.For this problem, develop a kind of stepped surface upgrading size mixing equipment based on energy adaptation, the difference of adaptive thickness beans is sized mixing energy requirement, and improve effect of sizing mixing, the efficiency utilization of intensified Daqu to the efficient separation and coal resources that realize Bed for Fine Coal is very meaningful.
Summary of the invention
The object of the present invention is to provide a kind of stepped surface upgrading paste mixer based on energy adaptation, the difference of adaptive thickness beans is sized mixing energy requirement, improves effect of sizing mixing, intensified Daqu operation.
The present invention is achieved through the following technical solutions:
A kind of stepped surface upgrading paste mixer based on energy adaptation of the present invention, comprises mixing cirtern, and mixing cirtern divides two sections to size mixing room, and two rooms of sizing mixing are separated by dividing plate, and mixing cirtern center is provided with cyclone classification parts, and is fixed by dividing plate.Described mixing cirtern is sized mixing bottom, room is provided with stock inlet, and stock inlet is connected with cyclone classification parts; Upper and lower two rooms of sizing mixing are provided with independent agitating device, and are provided with grout outlet on the top of two rooms of sizing mixing respectively, and bottom is provided with blowing mouth; And be provided with the independent dosing mouth of pipe in upper and lower two sides of sizing mixing room.
As can be seen from the technical scheme of the invention described above, a kind of stepped surface upgrading paste mixer based on energy adaptation of the present invention is owing to being provided with cyclone classification parts in mixing cirtern, ore pulp is after stock inlet enters mixing cirtern, through cyclone classification part classification, the shunting of ore pulp based on granularity thickness can be realized; A kind of stepped surface upgrading paste mixer based on energy adaptation of the present invention to be sized mixing room be furnished with independent agitating device and dosing mouth owing to being provided with upper and lower two, fine ore pulp ore pulp after classified by the top discharge mouth of cyclone classification parts enter mixing cirtern on to size mixing room, coarse-grained material ore pulp is sized mixing under entering mixing cirtern by the lower discharge port of cyclone classification parts room.On the agitating device of the room of sizing mixing configuration, energy input is high, and shear strength is large, is applicable to fine beans and sizes mixing; Under the room of sizing mixing configuration agitating device, energy input low, shear strength is little, and applicable Coarse Coal is sized mixing; After classification is sized mixing, size mixing from above room grout outlet of microfine ore pulp is discharged, and coarse grain ore pulp room grout outlet of sizing mixing by is down discharged.
A kind of advantage had based on the stepped surface upgrading paste mixer of energy adaptation of the present invention is, can adaptive thickness material for size mixing energy input demand non-equilibrium, the difference meeting thickness material ore pulp is sized mixing demand, entirety improves effect of sizing mixing, achieve the effective absorption of fine-particle minerals to the selective absorption of floating agent and Coarse Coal Mineral pairs floating agent, to solve in follow-up flotation operation the thin mud of the high ash of microfine and pollute cleaned coal due to poor selectivity and low grey Coarse Coal causes being lost in floating tail-coal owing to effectively not adsorbing collecting agent the problem causing clean coal yield to reduce, enhance flotation.
