For this reason, the utility model adopts the rotary single-barrel cooling machine which is provided with a feeding slide chute at the inlet, the feeding slide chute being equipped with a cold water tank, in the cooling machine being arranged a high-pressure strong wind system, on the exterior wall of the cooling machine being provided with cooling water sprinkling pipeline. The utility model has of the advantages of high cooling efficiency, convenient operation, cement quality assurance, environmental protection and safety.
Description
Technical field
The utility model relates to the cement production device field, particularly relates to the refrigerating unit of cement clinker.
Background technology
At present, aluminate cement grog refrigerating unit is different with the difference of its production technique, mostly adopt single cylinder cooling machine when adopting sintering process to produce, few employing planetary cooler is also arranged, so far as is known adopt grate cooler in addition, and adopt scorification to produce the refrigerating unit of aluminate cement clinker production technology, because clinker temperature is than higher (1500-1750 ℃) during molten state, should not adopt cartridge type cooler and grate cooler, method of cooling commonly used is to adopt to pour the tundish naturally cooling into, or pull out body of heater to the furnace wall method of cooling of spraying water, these two kinds of methods all have cooling efficiency low, inconvenient operation, even have potential safety hazard, it is unfavorable to the more important thing is the optimum shape of grog ore deposit phase lattice when cooling off, to the product performance generation detrimentally affect of aluminate cement.
For overcoming the deficiency of traditional refrigerating unit, enhance product performance, seek better refrigerating unit.
Summary of the invention
The novel purpose of this use is convenient to grog and is carried at low temperatures, stores, cement performance is improved favourable cement high temperature clinker refrigerating unit for providing a kind of speed of cooling fast.
The technical scheme that realizes above-mentioned purpose is; The cement high temperature clinker refrigerating unit has the single cylinder cooling machine of rotation, be provided with the charging chute in ingress, the charging chute is the external belt cold water storage cistern, be provided with high pressure strong wind inlet pipe in above-mentioned single cylinder cooling machine ingress, be provided with high pressure strong wind outlet pipe in the exit, be provided with the cool water shower pipeline at the single cylinder cooling machine outer wall.The outside set cold water storage cistern of charging chute is loaded on the bottom of charging chute, and high pressure strong wind inlet pipe passes cooling water tank and enters single cylinder cooling machine from the bottom.
The cool water shower pipeline is loaded on the top and the side of cooler outer wall, has a plurality of spray apertures on cool water shower, at its entrance of cooling water end spray water valve and topping-up pump is housed.
On high pressure strong wind outlet pipe, be connected with dust-precipitator.Charging chute and cooler ingress are made of refractory materials.Water-chilling plant below the charging chute prevents that the airduct mouth is out of shape because of the radiant heat of aluminate cement grog.In cooler, utilize the mechanical rotation of the gravity and the cooler of aluminate cement grog, grog is hung on the inwall uniformly.
The wind that enters cooler is supplied with by the high pressure gas bag of air compressor machine, and must control suitably by the size of its blast of valve regulated and air quantity, particularly wind nozzle outlet and with the position of aluminate cement grog.Molten aluminum acid salt cement grog enters monotubular formula cooler from the charging chute, aims at a large amount of blowings of charging chute outlet by the high pressure cold wind that air compressor produces, and direction is consistent with grog direction of motion, obtains chilling for the first time.Single cylinder cooling machine is by certain rotational speed simultaneously; make the fused grog evenly hang on the inwall; take away the most heat of grog by the wind that flows through rapidly in the tube; moreover single cylinder cooling machine top, a large amount of trickles in the left and right sides; heat radiation in time and protection cooler cylindrical shell also make the aluminate cement grog obtain cooling for the second time.
The amount of wanting regulated valve to make it to enter with the aluminate cement grog cooler when spraying into the high pressure strong wind in cooler adapts, and avoids producing a large amount of dust and mineral wool.Dust is captured with cooler dust-precipitator in succession simultaneously, and waste gas and heat are discharged.
The utlity model has following advantage:
1, cooling efficiency height of the present utility model.Because of the big blast height of air quantity, the cooling efficiency of refrigerating unit generally can reach more than 80%.This is this device by the characteristics of monotubular formula cooler and the decision of big air quantity, strengthens air quantity, blast at the material inlet place, the aluminate material of molten state is cooled to soon with interrogate speed so that next procedure the temperature of energy operation.
2, logistics direction is consistent with air flow line.General cement kiln refrigerating unit all is that the logistics direction is opposite with air flow line, cool off material by the negative pressure that kiln hood produces, and the present invention exactly in contrast, can make logistics pass through cooler smoothly.
3, environmental protection.Because the exit end of refrigerating unit is added with dust-precipitator, the fine dusts that produces when making the cooling of wind material is unlikely and enters atmosphere, has reduced topsoil.
4, easy to operate, can work continuously.It is slow with the interrupted production and the speed of cooling of tundish naturally cooling to have overcome molten materials, has improved working efficiency and day output.
5, safety.The utility model adopts rotary ventilation refrigerating unit, when having overcome with the tundish batch turning, and issuable fried bag, the danger that the splash phenomena of material is brought burn when reaching batch turning to the operator.
6, help the raising of the performance of aluminate cement.The material of molten is under the situation of the big air quantity chilling of high pressure, and the crystallization phases of aluminate cement grog, particulate size shape form well more to help the performance of cement performance, improves the quality of aluminate cement.
