Description
Technical field:
The present invention relates to a kind of solid particle material that is used to sieve, especially for the wind power sieving apparatus of solid particles such as screening coking coal.
Background technology:
Screening machine is that a kind of method with physics is separated into fine fraction and coarsely graded equipment with solid particle, is widely used in all fields such as metallurgy, chemical industry.Existing screening machine generally includes the electrodynamic type polytypes such as extension set and fluidized bed type screening machine, and wind power sieving apparatus that shake.
Motor-vibro screen formula screening machine is the equipment that generally adopts in the prior art, generally includes the unbalanced motor of finishing reciprocating motion or vibration in order to the drive screen cloth of screen cloth and rotation.This kind screening machine is in screening during solid particle material, is to rely on the reciprocating or vibration of the compass screen surface that tilts that fine grained in the solid particle on the screen cloth is spilt from screen cloth, and will discharges from the outlet on the sieve greater than the particle of mesh size.Though use this kind screening machine screening material efficient higher, but, because the quality of motor own and the volume that are adopted are all bigger, and need be equipped with heavy supporting member and moving parts, so, use this kind screening machine need relate to many equipment and roomy structures, also need more attendant and bigger maintenance cost simultaneously, and when work, can produce very big heat and noise; In addition; adopt the littler solid particle of screen cloth oscillatory type sieve diameter; be subjected to coating of particles and moisture in the material sometimes; and the restriction of viscosity; as easy bundle of the particle that has the tip makes sieve pore blockade on the mesh of screen cloth; and moisture is crossed conference and is made material produce the granulation tendency; making the particle that can be used as screenings originally go up outlet as oversize by sieve because of uniting discharges; even more serious is; the conference of solid particle material viscosity makes compass screen surface knot layer; and then cause screening machine can not normally finish the screening task, so, use the electrodynamic type screening machine can cause maintenance cost to improve and a large amount of production losses.
And the fluidized bed type screening machine comprises the gas distribution grid that has many holes, makes the fluidizing gas by the ejection of gas distribution grid below form fluid bed.This screening machine is to make classification of solid particles by the flow velocity of adjusting the gas that forms fluid bed, thereby solid particle is separated into coarse granule that is trapped in the fluid bed and the required fine grained that leaps out from fluid bed top.Pore stops up and gas distribution grid surface knot layer problem though this kind screening machine can solve, but this screening machine is had relatively high expectations to moisture content of material, as be used to sieve the used coking coal of coke oven, require the water content of coal not surpass 10%, when water content is higher than 10% in the coal, between the coal particle easily in conjunction with and form the bulky grain of bulk, at this moment, even if screening machine can be controlled the air quantity of fluidizing gas or the air quantity adjusting range of broad is arranged, also be difficult to make the bulk coal to be in the fluidisation attitude, it is trapped on the fluid bed, and under the more situation of bulk coal, the phenomenon that causes the fluidisation attitude to stop.
It is exactly a kind of improvement technology that proposes at the problems referred to above that the name of No. 1100112 Granted publications of Chinese patent is called " coking coal hot air blowing grading and moisture controlled coal preparation technology ".This coal preparation technology has disclosed a kind of fluidized bed drying technology, and making coal can be 200 ℃ in temperature--600 ℃ of atmosphere inner dryings and classification.Yet, with regard to regard to the screening machine of coke oven screening coking coal, require screening machine per hour can sieve out granularity 80 millimeters with 500 tons of interior coking coals to thousands of tons of, for the coal that is dried, if its fineness ratio is more even, in certain holdup time, may reach the desired aridity of fluidisation, but, under the big situation of the particle size distribution of coal, the bulky grain thing is because of can not get dry fully being trapped on the gas distribution grid, so it is very high to use this kind screening machine that the pulverizing program is required, and also needs to consume a large amount of heat energy and keep work; Simultaneously, high-temperature gas corrodes the gas distribution grid of fluid bed easily, needs expensive time and expense and change gas distribution grid; In addition, the quality of what and quality of coke oven output depends on the size of coking coal particle to a great extent, be that its particle diameter is more little, the interior coal dust of carbonization chamber of packing into is many more and careful, and its output is high more, and the quality of coke is good more, and this kind coal preparation technology must obtain fine grained by the winding-up mode highly that improves particle, but this mode not only improves energy consumption, but also can reduce output.
Summary of the invention:
The purpose of this invention is to provide and a kind ofly utilize pneumatic power that the mode of free-falling solid particle winding-up is sieved with solution to yield poorly and the wind power sieving apparatus of problem such as energy consumption height.
