Abstract
A rotary kiln tail sealing device is installed at a rotary kiln tail in a sleeving manner. A material return scoop of the rotary kiln tail is connected with a rotary kiln shell through a shell flange; a friction sleeve is installed on the outer periphery of the rotary kiln tail in a sleeving manner; a support plate of the sealing device is disposed on the outside of a smoke chamber in a sleeving manner; a connecting flange is fixed to the outer periphery of the shell flange and is connected with the friction sleeve; one end of the friction sleeve is fixedly connected with the upper end of an adjusting support and the lower end of the adjusting support is fixedly connected with the outer periphery of the rotary kiln shell; and the support plate and the friction sleeve are connected through a flexible sealing sheet and tensioning device. The rotary kiln tail sealing device is simple in structure; the effective contact area between the material return scoop and the shell flange is enlarged and the friction force is increased; the problem of bolt breakage is effectively solved, and thus the normal operation of a kiln system is guaranteed; an axial labyrinth seal is added, so that the wind speed is remarkably reduced and a sealing effect is achieved; the adjusting support can solve the problem in installation and adjustment of the friction sleeve effectively and guarantee that the friction sleeve does not deform easily; and the problems of air leakage and material leakage are solved.
Description
Technical field
The utility model relates to hermetically-sealed construction, especially a kind of sealing device for rotary kiln.
Background technology
Rotary kiln is that the industries such as metallurgy, chemical industry and cement are carried out the capital equipment of heat treated to loose unpacked material.The hermetically-sealed construction that seal of rotary kiln device is generally made by high temperature resistant, wear-resistant flexible material, comprising heat resisting steel flap, carbon sial composite plate, general steel plate flap and the flexible sealing structure that combines thereof, its integral body can be out of shape with the motion of rotary kiln, thereby adapts to kiln body deformability, cylindrical shell beat and bias that rotary kiln produces under applied at elevated temperature state.
Traditional rotary kiln sealing feed back spoon and friction sleeve are connected on body end surface flange with same bolt, often occur bolt fracture phenomenon, cause seal failure, and whole kiln system is in paralyzed state.Separately, because the working time increases, flap can wear and tear, and also easily causes seal failure, the material that not only leaks out, and affected the stable of rotary kiln thermal regulation, cause hear rate to increase, serious environment pollution.Separately due to friction sleeve diameter large, mutability, bolt hole adjustment amount is very little, in installation process, friction sleeve and rotary kiln center-aligned are very difficult.
Utility model content
The utility model is for the poor defect of existing rotary kiln hermetically-sealed construction sealing effectiveness, and a kind of good sealing effect, simple in structure, the easy rotary kiln tail sealing device of making are provided.
For achieving the above object, the utility model is by the following technical solutions: a kind of rotary kiln tail sealing device, sealing device is sleeved on rotary kiln, described rotary kiln is axially followed successively by along it smoke-box, feed back spoon and cylinder of rotary kiln being interconnected, feed back spoon is connected with cylinder of rotary kiln by shell flange, friction sleeve is sleeved on the excircle of this rotary kiln, described sealing device comprises gripper shoe, flexible sealing fin and take-up device and adjusting pole, wherein: gripper shoe is fixedly set in smoke-box outside; Adpting flange is fixed in shell flange excircle, and is connected with connector with the friction sleeve that is sleeved on rotary kiln outside; One end of described friction sleeve is fixedly connected with adjusting pole upper end, and the lower end of described adjusting pole and cylinder of rotary kiln excircle are affixed; Described gripper shoe is connected by flexible sealing fin and take-up device with friction sleeve.
This novel rotary kiln tail sealing device is simple in structure, and the effective contact area of feed back spoon and shell flange increases, and has increased frictional force; Friction sleeve is connected with cylindrical shell by adpting flange, effectively solves the problem of bolt fracture, has guaranteed the normal operation of kiln system, increased axial labyrinth seal, labyrinth seal allows air stream through bending channel, produces fluid resistance, wind speed is significantly reduced, played sealing function; Adjusting pole effectively solves friction sleeve the difficulty of adjusting is installed, and guarantees that friction sleeve is not yielding, and flap and friction sleeve are better fitted, and solves the problem of the material that leaks out.
Further scheme is: adjusting pole is uniformly distributed along cylinder of rotary kiln excircle.
Further scheme is: adjusting pole by adjust bolt and fixedly gusset form.
Further scheme is: gripper shoe is comprised of a circular flat board and two circular dividing plates, wherein between two dividing plates, arrange with one heart, and dividing plate and dull and stereotyped vertical setting.
Further scheme is: two dividing plates are separately positioned on the Internal and external cycle of friction sleeve, and described gripper shoe and friction sleeve form axial labyrinth seal structure.
Further scheme is: feed back spoon is connected with shell flange by two circle connecting bolts.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the utility model installation site schematic diagram.
Fig. 3 is the side view of Fig. 2.
In figure: gripper shoe 1, feed back spoon 2, flexible sealing fin and take-up device 3, friction sleeve 4, adjusting pole 5, cylinder of rotary kiln 6, large washer 7, adpting flange 8, shell flange 9, smoke-box 10.
The specific embodiment
Below in conjunction with drawings and Examples to this novel being described further.
Referring to accompanying drawing 2-3, this novel disclosed this sealing device is sleeved on rotary kiln.
Referring to accompanying drawing 1, rotary kiln is axially followed successively by along it smoke-box 10, feed back spoon 2 and cylinder of rotary kiln 6 being interconnected, feed back spoon 2 one end and smoke-box 10 are welded and fixed, the other end is connected with cylinder of rotary kiln 6 by shell flange 9, in the present embodiment, feed back spoon and shell flange junction are provided with inside and outside two circle connecting bolts.Friction sleeve 4 is sleeved on the excircle of this rotary kiln.
This sealing device comprises gripper shoe 1, flexible sealing fin and take-up device 3 and adjusting pole 5.Gripper shoe 1 is comprised of a circular flat board and two circular dividing plates, wherein between two dividing plates, arranges with one heart, and dividing plate and dull and stereotyped vertical setting, the flat board in gripper shoe is vertically welded on the excircle of smoke-box 10, and two dividing plates stretch out vertically.Adpting flange 8 is welded on shell flange 9 excircles, and is connected with connecting bolt with the support plate on friction sleeve 4, and tight type and sealing effectiveness for guaranteeing to connect, be set with large washer 7 on the connecting bolt of the two junction.One end of friction sleeve 4 is fixedly connected with adjusting pole 5 upper ends, the lower end of adjusting pole 5 and cylinder of rotary kiln 6 excircles are affixed, adjusting pole 5 by adjust bolt and fixedly gusset form, and a plurality of adjusting pole is uniformly distributed along the excircle of cylinder of rotary kiln 6, sees accompanying drawing 2.Between the dividing plate of gripper shoe 1 outer ring and friction sleeve 4 upper surfaces, by flexible sealing fin and take-up device 3, be connected.Two dividing plates are separately positioned on the Internal and external cycle of friction sleeve, and described gripper shoe and friction sleeve form axial labyrinth seal structure, and this labyrinth seal structure through bending channel, produces fluid resistance by air stream, and wind speed is significantly reduced, and plays sealing function.
