Description

The hydrocarbon black powder removal device

Technical field

The utility model is specifically related to a kind of hydrocarbon black powder removal device in carbon black manufacturing technology field.

Background technology

Carbon black is the important source material of rubber industry.Along with the development of rubber industry, more and more high requirement has been proposed for the carbon black that mainly adds reinforcing agent as rubber.Usually the carbon black pellet product contains the fine powder about 10%, too high fine powder content not only can pollute pack environment, the refining glue environment of Product transport, carbon black, also can influence carbon black package standard (apparent density changes and causes that Packing Capacity changes), and can the flow delivery systems of rubber industry be worked the mischief, too high fine powder content can influence the decentralization of carbon black in sizing material simultaneously, reduces the mechanical and physical performance of rubber.Therefore the fine powder content that reduces in the solid black has become a carbon black industry letter technical barrier to be solved.

At present, the approach that solves the carbon black fines too high levels mainly contains two kinds, and wherein a kind of mode is to improve the granulation effect of carbon black, and another kind of mode is the carbon black fines that adopts in the method removal carbon black pellet such as screening.But the common operation of these methods is comparatively numerous and diverse, with high costs, and effect is relatively poor, and may cause the more high side effect of breakage rate of carbon black pellet, reduces the economic benefit of manufacturer.

Summary of the invention

It is simple that the purpose of this utility model is to propose a kind of technology, removes the respond well hydrocarbon black powder removal device of carbon black fines, and to overcome deficiency of the prior art, the technical scheme that this method adopted is as follows:

For achieving the above object, the utility model has adopted following technical scheme:

A kind of hydrocarbon black powder removal device comprises powder remover fluid bed, it is characterized in that a horizontal sieve plate is set on the described fluid bed, is covered with the wind hole by the oblique through-fall plansifter of same direction plate on the horizontal sieve plate, and the sieve plate below is provided with pneumatic conveyer.

Particularly, described wind hole is by upper end deflection powder remover fluid bed discharge end, and the mode of lower end deflection powder remover fluid bed feed end is distributed on the horizontal sieve plate.

Described powder remover fluid bed comprises at least four selection by winnowing cooling sections, and its continuous distributed is between fluid bed feed end and discharge end, and each cooling section all is communicated with pneumatic conveyer, and the air-flow velocity of input is adjustable.

All establish an airflow pipeline that has a flow rate regulating valve in described each selection by winnowing cooling section in horizontal sieve plate below, these airflow pipeline are communicated with pneumatic conveyer.

Described powder remover fluid bed top is communicated with a hydrocarbon black powder gathering-device, and this hydrocarbon black powder gathering-device comprises the filter bag device.

The utility model adopts fluidized-bed process that carbon black pellet is handled, to remove the fine powder in the carbon black pellet, its technological process is: the carbon black pellet that contains fine powder behind granulating and drying, add powder remover fluid bed quantitatively by equipment such as elevator and magnetic separators, in fluid bed, carry out selection by winnowing, finished particle is discharged by auger conveyor from equipment one end, to the finished product storage tank, powder is discharged from the equipment top, this technological process is succinct, can realize in enormous quantities, fast processing to carbon black pellet, efficiency far is better than prior art.The concrete principle of this technology is: under the air-flow effect of importing below by fluid bed, quality is blown to raise to the fluid bed top less than the fine powder of carbon black pellet discharges, and can be by collecting of being communicated with fluid bed top with the hydrocarbon black powder gathering-device, in order to returning granulating system once more, the carbon black pellet that quality is bigger then passes through fluid bed with suspended state.

For realizing above-mentioned technology, be provided with a horizontal sieve plate in the above-mentioned hydrocarbon black powder remover fluid bed, be covered with the oblique wind hole that penetrates sieve plate of mode of being partial to fluid bed feed end and discharge end by upper and lower end respectively on this sieve plate, when air communication is crossed sieve plate, air-flow in vertical direction deflection certain angle, can be when carbon black pellet be blown afloat suspension, the promotion carbon black pellet moves towards the direction of discharge end, and the fine powder in the carbon black pellet is then discharged to the top with oblique the waving of air-flow.

Again, through the carbon black pellet temperature behind the granulating and drying generally more than 130 ℃, usually need cool off it in the front and back that screen out fine powder in the prior art, so that pack or subsequent treatment, the air-flow that feeds powder remover fluid bed in the utility model is the normal temperature air-flow, then in removing carbon black pellet, in the powder, carbon black pellet can be cooled to 60～70 ℃, further simplify the processing technological flow of carbon black pellet.

Above-mentioned hydrocarbon black powder remover fluid bed can comprise at least four selection by winnowing cooling sections, its continuous distributed is between fluid bed feed end and discharge end, horizontal sieve plate is set on each cooling section, and its below is provided with pneumatic conveyer respectively, as air blast etc., like this, can carry out the classification selection by winnowing to carbon black pellet, each grade fluidizing velocity is adjustable, can effectively improve classification efficiency like this and rationally utilize energy, after selection by winnowing repeatedly and cooling, the fine powder residual rate in the carbon black pellet can be reduced to 0.4%～2.0%.

Compared with prior art, the beneficial effects of the utility model are: this hydrocarbon black powder removal device adopts the mode of product being carried out selection by winnowing under suspended state, powder clearance height, the finished product breakage rate is low, can realize simultaneously the cooling of product, meet carbon black and store requirement, improve terms of packing, it is simply efficient to have technology, the advantage that economizes on resources, the device structure advantages of simple of this process using is easy to produce and safeguards, and can effectively improve the selection by winnowing cooling effectiveness, can also realize the reasonable utilization of energy.This hydrocarbon black powder removal device can be widely used in the carbon black pellet processing technology field, effectively improve production efficiency and product quality.
