Description
Technical field
The utility model relates to a kind of intake adjusting device, especially is applied to the cooling air intake adjusting device of cooler.
Background technology
Cooler is equipment very important in the manufacture of cement, is bearing the task such as cooling, conveying, recuperation of heat of clinker.Main Function on cement industry mainly is that the high temperature chamotte that rotary kiln draws off is cooled to the temperature that conveyer, storage vault and the cement grinding mill in downstream can bear, simultaneously the sensible heat of high temperature chamotte is reclaimed into secondary, tertiary air and the dry air of firing system as kiln, improve the thermal efficiency of whole firing system.Cooler passes through from the grog of high temperature take air as medium, and grog is cooled off, and reclaims simultaneously the heat of waste gas, improves the thermal efficiency of kiln.The cooldown rate of grog is to the structure of grog and the mineral composition of grog, and the nonferromagnetic substance of grog and the quality of cement all have a great impact.
At present widely used reciprocating slide slotted cooler considers that comprehensively (thickness of feed layer, particle form) and the regularity of distribution of material temperature of length, width divide cooled region on market.But in running, there is certain problem, as: cooling air quantity is bigger than normal, allocation of the amount of air is inhomogeneous, SR is large, power consumption is large, and systematic running cost is with high.
How the existing grate cooler no matter thickness of the bed of material or the size of particle changes, and its cooling air quantity almost is the same, this just caused the fines layer to pass through air quantity few, cool off insufficient; The air quantity that the coarse fodder layer passes through is large, the waste of air quantity.It is not equipped with the cooling air that can regulate pointedly, makes its air-distribution in less zone even, carries out fully heat exchange between cold wind and the grog, accurately controls the air quantity of using of each cooled region.
Summary of the invention
Technical problem to be solved in the utility model is that its cooling air quantity of existing cement clinker cooler can not be regulated automatically, and a kind of intake adjusting device that can regulate according to the bed of material drag size intake is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is that the intake adjusting device comprises blast pipe, and described blast pipe sidewall is provided with air inlet; Also comprise at least two adjustable plate and adjustable plate axle; The adjustable plate axle is installed on the blast pipe; Adjustable plate is rotatably connected on the adjustable plate axle.
Further improvement of the utility model is that the length and width of each adjustable plate is identical, and thickness is different.
The utility model compared with prior art, its beneficial effect is: (1) cooling air quantity evenly, cooling evenly; (2) systematic running cost is low; (3) automatically regulate intake according to bed of material drag size.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is a kind of typical stream condition curve synoptic diagram of intake adjusting device.
Fig. 3 is specific embodiment of the utility model 1 structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Operation principle of the present utility model: when the drag reduction of grog layer, at this moment the increase of blast pipe inside and outside differential pressure, follow-up unit rotates so that the draught area of capable of adjusting air inlet mouth reduces, and because the increase of pressure reduction, rate of flow of fluid increases, and both Joint effects are so that the flow of air inlet is tending towards constant.On the contrary, when the resistance of grog layer increases, reducing of blast pipe inside and outside differential pressure at this moment, follow-up unit rotates so that the draught area of capable of adjusting air inlet mouth increases, and simultaneously, because rate of flow of fluid reduces, both Joint effects are so that the flow of air inlet is tending towards constant.So no matter how the grog stressor layer changes, the cooling medium by the bed of material can both remain on suitable amount.
As improvement, the capable of adjusting air inlet mouth is opened on the sidewall of blast pipe; Rotate the air regulating board with Different Weight in capable of adjusting air inlet mouth scope, air regulating board is around the air regulating board axle that rotates.
The setting of the air regulating board of Different Weight is the assurance that this device obtains the constant flow rate fluid.The air regulating board that Different Weight is set can be closed first at lighter air regulating board in the drag reduction process of grog layer, when the resistance of grog layer continues to reduce, heavier air regulating board continues to close, until the air regulating board Close All, only the gap between the surplus air regulating board is as fixedly ventilating opening ventilation.Weight by adjusting air regulating board and the area of opening can obtain the stream condition curve of regime flow.
By reference to the accompanying drawings 1-accompanying drawing 2 explanations,
Suppose that such as Fig. 3 the present embodiment has 5 adjustable plates, the weight relationships between each adjustable plate is: adjustable plate 7＜adjustable plate 8＜adjustable plate 9＜adjustable plate 10＜adjustable plate 11.
Capable of adjusting air inlet mouth 3 is opened on the sidewall of blast pipe 1.Adjustable plate axle 5 is installed on the blast pipe 1; Adjustable plate 7, adjustable plate 8, adjustable plate 9, adjustable plate 10 and adjustable plate 11 are installed on the adjustable plate axle 5 successively, and can be around 5 rotations of adjustable plate axle.Clamp nut 6 is installed in an end of adjustable plate axle 5, so that adjustable plate can not be along moving axially.
When the drag reduction of grog layer, intake adjusting device up and down pressure reduction increases, and the lightest adjustable plate 2 rotates, closes, and has reduced draught area; Close successively adjustable plate 3, adjustable plate 4, adjustable plate 5, adjustable plate 6 when the resistance continuation minimizing of grog layer, reduce draught area; Because intake adjusting device up and down pressure reduction increases, gas flow rate by the intake adjusting device also constantly increases, and the width of adjustable plate is to design according to different gas flow rates with quantity, therefore can obtain a stable draft, satisfies the cooling of material and also avoids the air-flow waste.
When the thickness of the bed of material or distribution of particles change, the pressure drop of the bed of material and the requirement of cooling medium also changed thereupon.For existing cooler, bed of material attenuation, bed of material pressure drop reduces, air compartment and cooler inner fluid pressure reduction increase, and the cooling medium flow velocity is accelerated, thereby increase by this regional Fluid Volume, cause unnecessary waste, increased the consumption of blower fan, also affected the wind-warm syndrome of Secondary Air and tertiary air.And for having increased grate plate of the present utility model, when bed of material attenuation, bed of material pressure drop reduces, air compartment and cooler inner fluid pressure reduction increase, the cooling medium flow velocity is accelerated, and under the effect of air compartment and cooler inner fluid pressure reduction, adjustable plate produces the circulation area that action has reduced fluid, and the cooling medium that passes through the bed of material that makes remains on suitable amount.
