Abstract
The utility model relates to a kiln tail sealing device for a cement rotary kiln. The kiln tail sealing device comprises a smoke chamber and a kiln body, wherein a fixed sealing ring is welded at the tail end of the smoke chamber; a movable friction ring is arranged on the kiln body through two supporting blocks; an elastic stainless steel sheet capable of sliding on the movable friction ring is arranged at the outer edge; the only one supporting block is positioned in the middle of the movable friction ring; and the two supporting blocks are positioned at two ends of the movable friction ring. The kiln tail sealing device for the cement rotary kiln realizes sealing in a manner that the elastic stainless steel sheet slides on the movable friction ring, so that air leakage amount on the kiln tail is reduced, and a ventilation effect in the kiln is relatively good; the using amount of air in the kiln is enough; coals are completely forged stably; phenomena of low lifting weight and ring forming are almost avoided; and the table yield and the clinker quality are improved greatly.
Description
Technical field
The utility model relates to a kind of cement rotary kiln kiln tail sealing device, and particularly a kind of architecture advances of cement rotary kiln kiln tail sealing device belongs to the cement rotary kiln technical field.
Background technology
Cement rotary kiln is the capital equipment of clinker dry method and wet production line.Rotary kiln is widely used in industry such as metallurgy, chemical industry, building refractory material, environmental protection.There is the slit inevitably in kiln tail at cement rotary kiln, for stop extraneous air to be inhaled in the kiln or in the kiln gas carry material and leak, on the kiln tail of cement rotary kiln sealing device must be set.
The kiln tail of general cement rotary kiln leans on movable sealing circle 1 to move forward and backward (shown in the accompanying drawing 1) that seals; When kiln body 2 upwards promotes static friction sheets 3 by movable friction plate 4 during play movable sealing circle 1 is moved up, when the downward play of kiln body 2, spur movable sealing circles 1 and move down by balancing weight 5.But actually be, when counterweight was heavy, two friction disc wears were serious, and service life is short, and when counterweight was light, the stretchy sealing ring did not move down, and moved ineffectively, do not have sealing effectiveness.Such sealing device causes the kiln tail to leak out seriously, and kiln ventilation is poor, and thermal regulation is difficult to stable, low rise heavy, ring formation phenomenon often occur, and unit-hour output, clinker quality is on the low side.
The utility model content
The utility model purpose is for the deficiency that overcomes prior art a kind of good seal performance, the good cement rotary kiln kiln tail sealing device of result of use to be provided.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of cement rotary kiln kiln tail sealing device, comprise smoke-box and kiln body, and the tail end of said smoke-box is welded with fixed seal ring; Through back-up block movable dead turn is installed on the said kiln body; The outer edges and corners of said fixed seal ring are provided with can be at the elastic stainless steel sheet of movable dead turn slip.
Preferably, said back-up block is one, is positioned at the middle part of movable dead turn.
Preferably, said back-up block is two, is positioned at the two ends of movable dead turn.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The cement rotary kiln kiln tail sealing device of the utility model; Through the elastic stainless steel sheet on movable dead turn, slide realize the sealing, make the kiln tail leak out and reduce that kiln ventilation is clearly better; Satisfied and used wind in the kiln; Coal combustion is calcined stable fully, low rise heavy and ring formation phenomenon seldom occur, and unit-hour output, clinker quality have increased significantly.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the structural representation of the cement rotary kiln kiln tail sealing device of prior art;
Accompanying drawing 2 is the structural representation of the cement rotary kiln kiln tail sealing device of the utility model;
Wherein: 1, movable sealing circle; 2, kiln body; 3, static friction sheet; 4, movable friction plate; 5, balancing weight; 6, smoke-box.7, fixed seal ring; 8, back-up block; 9, movable dead turn; 10, elastic stainless steel sheet.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of cement rotary kiln kiln tail sealing device of the utility model shown in accompanying drawing 2 comprises smoke-box 6 and kiln body 2, and the tail end of said smoke-box 6 is welded with fixed seal ring 7; Through back-up block 8 movable dead turn 9 is installed on the said kiln body 2; The outer edges and corners of said fixed seal ring 7 are provided with can be at the elastic stainless steel sheet 10 of movable dead turn 9 slips; Said back-up block 8 is one, is positioned at the middle part of movable dead turn 7; Said back-up block 8 is two, is positioned at the two ends of movable dead turn 10.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The cement rotary kiln kiln tail sealing device of the utility model; Through the elastic stainless steel sheet on movable dead turn, slide realize the sealing, make the kiln tail leak out and reduce that kiln ventilation is clearly better; Satisfied and used wind in the kiln; Coal combustion is calcined stable fully, low rise heavy and ring formation phenomenon seldom occur, and unit-hour output, clinker quality have increased significantly.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
