Abstract
The invention discloses a kiln head cooling device of a dry process kiln. A cold wind sleeve is connected with a kiln head barrel by a steel plate, a fixed base is fixed on the inner wall of the cold wind sleeve, one end of the steel plate is hinged with the fixed base, and the other end is fixed on the kiln head barrel. The invention changes backup plate rigid connection in the prior art into elastic connection and enhances the heat resistance and the expansion limit of a connecting piece; the connection mode of hinging provides expansion buffering capacity for the connecting piece, so that the connecting piece has small possibility of ripping, has long equipment operation period and greatly lowers maintenance cost. The equipment of the invention is firm, and the kiln head has favourable cooling and protecting effect; the kiln head has no blown sand and has clean working environment; meanwhile, the kiln has stable inlet air, and the quality and the yield of the product are improved.
Description
Technical field:
The present invention relates to cement producing line, relate in particular to the dry-process rotory kiln production line, be specifically related to the kiln hood cooling device.
Background technology:
The kiln hood cooling device is the protection equipment of dry-process rotory kiln kiln hood break iron and kilneye cylindrical shell; generally be at kiln hood cylindrical shell peripheral hardware cold wind shroud; by connector cold wind shroud and kiln hood cylindrical shell are fixed up, cold wind shroud and the run-in synchronism of kiln hood cylindrical shell in the production realize the cooling of kiln hood.In the existing production technology, two backup plates that normally will be connected as a single entity are separately fixed on cold wind shroud and the kiln hood cylindrical shell to realize the fixing of the two.Yet, under the continuous high temperature working environment, connect the backup plate weld bond and often drawn back, even connecting bolt is cut off, cause the motion of cold wind shroud and kiln body asynchronous, cold wind shroud waves play, departs from the kiln hood break iron, lose cooling effect, in the serious service life of watering material feeding that shortens kiln hood break iron surface coverage, it successively peels off, and makes break iron exposed and by scaling loss, oxide etch, kilneye air-cooler cooling air ozzle is also often squeezed off in addition, increases the labour intensity and the equipment part consumption of plant maintenance; Simultaneously, the kilneye cylindrical shell damages, distortion, and rotary system is leaked out seriously, the calcining air quantity assurance that supply two in the kiln and in the dore furnace, tertiary air can not get equalization stable, and the quality and the output of calcination grog are affected; Have, the blown sand amount of kilneye increases, and influences finishing of cleaner production and dust emission index again.
Summary of the invention:
The purpose of this invention is to provide a kind of being connected firmly, the heat-resisting coefficient of expansion of connector is big, bears the good kiln head cooling device of dry process kiln of pulling force and shearing force under hot environment.
Kiln head cooling device of dry process kiln of the present invention comprises cold wind shroud, connector, and cold wind shroud is located at outside the kiln hood cylindrical shell, and several connectors are connected between cold wind shroud and the kiln hood cylindrical shell, and described connector is a steel plate, and steel plate is connected in hinged mode with cold wind shroud.
The sensing of steel plate is the tangential direction of dry method kiln cylinder body.
Steel plate evenly distributes along circumference.
Steel plate is hinged by firm banking and described cold wind shroud, and firm banking is fixed on the cold wind shroud inwall, and firm banking has groove, has hinge hole on the relative wall of groove; The hinged end of described steel plate has corresponding hinge hole.
The hinge hole of steel plate hinged end, its implementation is: fix a short tube at the steel plate end, the short tube pore is corresponding with hinge hole on the described firm banking.
Steel plate and firm banking hinged place are provided with cushion pad.
The present invention, connector between cold wind shroud and the rotary kiln end cylindrical shell has adopted steel plate, change the rigid connection of backup plate formula of the prior art into elasticity and connect, strengthened the hear resistance and the expansion limit of connector, hinged connected mode provides the expansion buffering capacity to connector again.Steel plate points to the tangential direction of cylinder of rotary kiln, can reduce the air intake resistance, increases draught area.Steel plate evenly distributes along circumference, makes equipment operation steadily balanced.Cooling device of the present invention is connected firmly, and makes: connector is difficult for drawing crack, and the cycle of operation is long, and maintenance cost reduces significantly; Kiln hood cools off, protection is effective, and kiln hood does not have blown sand, the working environment cleaning; Stable inlet air in the kiln, product yield, quality improve.

The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1; dry-process rotory kiln kiln hood cooling device of the prior art; comprise cold wind shroud 1, kiln hood cylindrical shell 3; cold wind shroud is located at outside the kiln hood cylindrical shell, connects backup plate 2 the two is connected and fixed, during the equipment operation; cold wind shroud 1 and 3 run-in synchronisms of kiln hood cylindrical shell; cold wind blows to protection iron and drum surface by cold wind shroud and kiln hood cylindrical shell joint gap, and kiln hood break iron and kiln hood are cooled, and plays the effect of protection.Connect backup plate and weld together with cold wind shroud inwall, kiln hood cylindrical shell respectively, connecting backup plate is two metallic plates of fixing by bolting or other modes.Because kiln hood environment temperature height, the thermal expansion amount and the connected load that connect backup plate are very big, when reaching weld bond or connecting bolt and bear the limit, weld bond can snap or connecting bolt is cut off, then cold wind shroud waves play, and its running is asynchronous with the running of kiln body, and kilneye cap iron can not get timely cooling, serious wear, strengthened plant maintenance workload and cost, in addition, the kiln hood cylindrical shell damages, distortion, cause rotary system to leak out, influence the burning quality and the output of grog in the kiln.
The equipment of present embodiment comprises cold wind shroud 1, kiln hood cylindrical shell 3 as shown in Figure 2, and cold wind shroud is located at outside the kiln hood cylindrical shell, and the two is fixed and run-in synchronism by connector.Connector comprises steel plate 4, and firm banking 5, firm banking 5 are fixed on cold wind shroud 1 inwall, and an end and the firm banking 5 of steel plate 4 are hinged, and the other end is welded on the kiln hood cylinder body outer wall along the direction of rotary kiln rotation, and steel plate points to the tangential direction of cylinder of rotary kiln.
Firm banking as shown in Figure 3, it has groove 6, has hinge hole 8 on the relative cell wall.Its side of an end that steel plate is connected with firm banking has corresponding hinge hole, hinge hole can be directly to form as the hole at the steel plate end, in order to reduce wear, gain in strength, also can be as shown in Figure 4, at short tube 9 of terminal crosswise fixed of steel plate 4, the mouth of pipe is in the steel plate side, and the short tube hole promptly becomes hinged mouthful.Steel plate 4 is with firm banking when hinged, as shown in Figure 5, the hinged end of steel plate inserted in the groove 6 of base, make hinged mouthful 8 relative with the hole of short tube 9, in the bolt 7 insertion hinge holes steel plate and firm banking are hinged together.
In order to guarantee steel plate expansion buffering capacity, shimming asbestos board between the groove of steel plate and firm banking.
