Description
Technical field
The utility model relates to liquid-solid fluid bed separation equipment, and especially a kind of particle diameter that is applicable to is the spiral lift flow type liquid-solid fluid bed separation equipment that the coarse slime of 2-0.3mm carries out sorting.
Background technology
Along with the raising of mining mechanization degree, in raw coal, fine particle content is on the increase, and comes difficult to slime water treatment system band.At present, the heavy-media coal preparation process of China takes preparation of unsized raw coal and No severing mud to be selected in mostly, and equipment trend maximizes.Although this way simplifies technique, be unfavorable for the efficiency of separation improving wholegrain level coal, and existing equipment sharpness of separation does not reach technological requirement yet.The sorting particle size range of heavy medium cyclone is 50 ~ 0.15mm, but production practices show, when dense medium cyclone diameter is more than 750mm, sharpness of separation for <3mm grade (3 ~ 0.15mm) material is poor, the sorting particle size range of flotation device is <0.5mm, but only can realize effective sorting to <0.3mm material aborning, and the coarse slime of >0.3mm is very easily lost in mine tailing because of the carrying capability deficiency of bubble in floatation process.Therefore, between gravity treatment and flotation, there is the breach of an effective sorting granularity, namely gravity treatment is along with the reduction of granularity, and the efficiency of separation declines, and flotation is then along with the increase of granularity, and the efficiency of separation progressively reduces.Thus granularity be in gravity treatment and flotation effective sorting scope have a common boundary near the coal grain efficiency of separation minimum.Therefore, the effective sorting realizing coarse slime is one of current coal separation industry problem demanding prompt solution.
To the sorting of coarse slime in 2-0.25mm particle size range, it is the weak link of existing coal preparation technique.Lack the development equipment of this particle size range height sharpness of separation seriously being constrained to coal preparation technique, become the bottleneck problem that coal preparation plant ensures product quality, increases economic efficiency gradually.Only have the effective sorting problem solving coarse slime processing links, the pollution to cleaned coal could be reduced, ensure the maximization of wholegrain level quality of cleaned coal and productive rate.
At present, the screening installation of >0.3mm grade coal slime mainly contains: spiral, fine coal properties matter cyclone, hindered bed separator etc.Spiral, grading principle is the difference stressed on spiral groove face of different densities particle and produces the difference of its motion component velocity, is finally presented as that the distribution along spiral groove face radial direction is different, thus makes the particle of different densities complete sorting.Have good separating effect for easy coal separation, but fuselage height is large, during coal varitation, technological parameter not easily regulates, and when separating density is lower, separating effect is poor.It is higher to fluctuate bad adaptability, separating density of pan feeding, restricts the key that it applies in separation of coarse slime; The density of the heavy suspension of Slime dense medium cyclone is close to separating density, and thus sharpness of separation is high.Its shortcoming is the impact that separating effect is subject to the factor such as granularity and Algorithm of Density Control of coal slime medium solid; Hindered bed separator disposal ability is large, with regard to its grading principle, ascending current flow velocity is the important operation parameter affecting its quality of cleaned coal and productive rate, and ascending water speed is directly affected on the control of underflow, the underflow of hindered bed separator controls to be by automatically adjusting to the mensuration of flow velocity, but existing automatic detection and control system imperfection, can not real-time tracking completely to the control of underflow, the instability of whole assorting room will be caused like this, affect quality and the productive rate of cleaned coal.
Summary of the invention
Technical problem: the purpose of this utility model overcomes weak point of the prior art, provide that a kind of structure is simple, simple operation, production cost is low, treating capacity is large, product structure is easy to adjustment spiral lift flow type liquid-solid fluid bed separation equipment.
Technical scheme: of the present utility model kind of spiral lift flow type liquid-solid fluid bed separation equipment, comprise frame, be located at the sorting post of upper rack and be located at the motor of frame lower, the power transmission shaft through sorting cylinder is provided with in described sorting post, power transmission shaft bottom is connected with motor output shaft through bearing, shaft coupling successively, and power transmission shaft upper end is fixed on frame top through bearing; Power transmission shaft in described sorting post is fixed with helical blade, the bottom of sorting post is provided with underflow pipe, underflow pipe top is provided with oral siphon, and the downflow weir sidewall of sorting post is provided with the feeding pipe fed intake to sorting post, and the bottom of sorting post is provided with the seal receptacle preventing ore pulp from flowing out.
The cylinder of described sorting post is that lucite is made.
Described motor is made up of frequency converting speed regulating three-phase asynchronous electromotor and variable-frequency governor.
Beneficial effect: the utility model is on the basis of hindered bed separator, add one group of helical blade upwards rotated, the power of reinforcing particle rising, reduces the solid solvent concentration of separator bottom particles, is more conducive to the displacement of different densities particle to a certain extent.Promote with under ascending current acting in conjunction at helical blade eddy flow, stable fluid bed is defined in sorting body, significantly reduce the solid solvent concentration gradient change on height of column direction, improve the loose condition (of surface) of fluidization bed, facilitate the fluency of particle displacement motion, thus significantly improve separating effect, make separator still can obtain good separating effect when material size wider range, can ensure that fluid bed is stablized, make separator still can obtain good separating effect when material size wider range, by the situation regulating the rotating speed of motor can adjust separator easily according to the ature of coal situation of feed coal and the quality requirement of product, the accommodation of material size is large, sharpness of separation is high, can effectively to wide rank, difficulty selects coarse slime to carry out sorting, meet the needs of actual production, simultaneously, the utility model structure is simple, simple operation, do not need outer adding medicine, flow process is simple, take up an area less, economy and durability, solve preferably the efficiency of separation and medicine consume between contradiction.Effectively reduce cleans ash, decrease dense medium back of the body meeting phenomenon, add the clean coal yield of coal preparation plant, improve economic benefit.
