Abstract
The utility model relates to a rotary kiln sealing structure which comprises a discharging cover, a rotary kiln pipe and a flange A. A flange fixed base is arranged on the rotary kiln pipe, and a flange B is fixed on the flange fixed base. The flange A is contacted with the flange B, a groove A, a groove C and a groove B are arranged on an end surface where the flange A is contacted with the flange B, the groove B is used for communicating with nitrogen, the groove B is arranged between the groove A and the groove C, copper bar sealing rings are embedded in the groove A and the groove C, and a telescopic joint is arranged between the other end surface of the flange A and the discharging cover. The rotary kiln sealing structure is simple in structure, good in sealing effect, and capable of adjusting a degree of tightness between the flange A and the flange B at any time through a compression spring and a locking nut, guaranteeing sealing performance, simultaneously carrying out compensation by arranging of the telescopic joint, and avoiding the phenomenon in the process of working of the flange A, such as abrasion and vibration, wherein the phenomenon can influence the sealing performance.

Technical field
The utility model relates to the seal of rotary kiln device, particularly a kind of seal of rotary kiln structure.
Background technology
Rotary kiln is that the industry of metallurgy, chemical industry, cement is carried out the capital equipment of heat treated to loose unpacked material, generally in pressure-fired work.Partly and between the fixing jockey there is the slit in entire body at rotary kiln inevitably; the rotary kiln rotary kiln need pass into protective gas or reducibility gas when sintered products; consider for saving the aspects such as cost, environment, safety; these gases can not spill outside the kiln pipe, so need to seal rotary kiln.
Summary of the invention
The objective of the invention is for the problems referred to above, a kind of seal of rotary kiln structure is provided.
For achieving the above object, the method that the present invention adopts is: a kind of seal of rotary kiln structure, comprise the discharging cover, the rotary kiln pipe, be provided with the flange firm banking at the rotary kiln pipe, be fixed with flange B at the flange firm banking, described seal of rotary kiln structure also comprises a flange A, flange A places on the flange B, the end face that flange A contacts with flange B has groove A, groove C, the groove B, the groove B that are used for logical nitrogen are located between groove A and the groove C, stud with the copper rod sealing ring in groove A, the groove C, are provided with telescopic joint between another end face of flange A and the discharging cover.
As a kind of improvement of the present utility model, described seal of rotary kiln structure also comprises screw rod and roller fixture, and described screw rod is arranged on the flange A, and screw rod links to each other with the roller fixture, another end face at described flange B is provided with roller, and roller links to each other with the roller fixture by axle.
As a kind of improvement of the present utility model, between screw rod and flange A, be provided with holddown spring, be provided with locking nut at screw rod.
As a kind of improvement of the present utility model, described telescopic joint two ends link to each other with the discharging cover with flange A with screw by flange.
The utility model reaches following beneficial effect by above setting: the utility model is simple in structure, good sealing effect, can adjust at any time degree of tightness between flange A and the flange B by Compress Spring and locking nut, guarantee sealing property, by being set, telescopic joint compensates simultaneously, prevent flange A wearing and tearing in the course of the work, the phenomenons such as vibration affect sealing property.
Description of drawings
Fig. 1 is structural representation of the present invention;
Each member is among the figure: 1, discharging cover 2, telescopic joint 3, clamp nut 4, holddown spring 5, flange A 6, roller 7, flange B 8, flange firm banking 9, rotary kiln pipe 10, groove A 11, groove B 12 groove C 13, screw rod 14, roller fixture.
The specific embodiment
The invention will be further described below in conjunction with embodiment and with reference to accompanying drawing.
A kind of seal of rotary kiln structure as described in Figure 1, comprise discharging cover 1, rotary kiln pipe 9, be provided with flange firm banking 8 at rotary kiln pipe 9, be fixed with flange B7 at flange firm banking 8, described seal of rotary kiln structure also comprises a flange A5, flange A5 contacts with flange B7, relative motion between flange A5 and the flange B7, the end face that flange A5 contacts with flange B7 has groove A10, groove C12, for the groove B11 of logical nitrogen, groove B11 is located between groove A10 and the groove C12, groove A10, stud with the copper rod sealing ring in the groove C13, be provided with telescopic joint 2 between another end face of flange A5 and the discharging cover 1.
A kind of improvement of the present utility model, described seal of rotary kiln structure also comprises screw rod 13 and roller fixture 14, described screw rod 13 is arranged on the flange A5, screw rod 13 links to each other with roller fixture 14, another end face at described flange B7 is provided with roller 6, and roller 6 links to each other with roller fixture 14 by axle.
A kind of improvement of the present utility model is provided with holddown spring 4 between screw rod 13 and flange A5, be provided with locking nut 3 at screw rod 13.
A kind of improvement of the present utility model, described telescopic joint 2 two ends link to each other with discharging cover 1 with flange A5 with screw by flange.
The utility model is when work, and rotary kiln rotarily drives flange B7 and rotates together, and flange A5 and flange B7 produce relative motion.
Equipment uses the initial stage, pass through the end face of compact lock jack panel 3 and holddown spring 4 supported flange A5 and flange B7 during the rotary kiln rotation, so that two circle copper rod sealing rings frictions on while flange B7 and the flange A5, advance the nitrogen of certain pressure with time slot B11, nitrogen is between two circle copper sealing rings and keep certain pressure, a small amount of nitrogen flows in the rotary kiln and flows out outside the rotary kiln, has guaranteed that so the inside and outside gas of rotary kiln do not gang up, and seals.
After equipment uses a period of time, because copper rod is worn, flange A5 flange B7 rubs mutually during the rotary kiln rotation, form two light faces, this moment is by the end face of clamp nut 3 and holddown spring supported flange A and flange B, because flange A wearing and tearing in the course of the work, the phenomenons such as vibration affect sealing property, so a telescopic joint 2 is set, is used for the effect of compensation.Groove B advances the nitrogen of certain pressure, can guarantee that so still the inside and outside gas of rotary kiln do not gang up, and seals.
The utility model is simple in structure, good sealing effect, can adjust at any time degree of tightness between flange A and the flange B by holddown spring 4 and locking nut 3, guarantee sealing property, by being set, telescopic joint compensates simultaneously, prevent flange A wearing and tearing in the course of the work, the phenomenons such as vibration affect sealing property.
The above; it only is preferred embodiment of the present utility model; be not to be the restriction of the utility model being made any other form, and according to any modification or equivalent variations that technical spirit of the present utility model is done, still belong to the utility model scope required for protection.
