Abstract
The utility model relates to a sealing device for rotary kilns, which is suitable for sealing among a kiln head, a kiln tail and a barrel body. The utility model comprises a sealing ring fixed to the barrel body, sealing sheet seats fixed to the kiln head and the kiln tail, sealing sheets arranged in a sealing sheet seats, a spring and an adjustment bolt. The utility model is characterized in that long holes are arranged on the sealing sheets which are connected with the sealing sheet seat by the long holes to form a round ring of the sealing sheet; an eccentric adjustment ring is arranged between the barrel body and the sealing ring; an inner circle is connected with the barrel body and an outer circle is connected with the sealing ring; the round ring composed of the sealing sheets is sheathed and pressed on the sealing ring. The utility model has the advantages of good sealing effect and long service life.
Description
The utility model relates to a kind of Sealing of Rotary Kiln device, is applicable to the sealing between kiln hood, kiln tail and the cylindrical shell.
Rotary kiln is one of capital equipment that uses in aluminium oxide, cement and other chemical metallurgy process of producing product, when it moves, certainly exist certain clearance between rotary cylinder body and static kiln hood, the kiln tail, if seal bad, will be by this gap a large amount of cold air that bleeds, thus cause the rotary kiln energy consumption to increase, production capacity is low, product quality descends, and increases maintenance load simultaneously, influences the running rate of rotary kiln.Therefore, sealing device is a necessary part in the rotary kiln device.Existing sealing device, generally can be divided into two kinds of forms: a kind of is non-contacting seal, i.e. labyrinth sealing, and this sealing is owing to be subjected to the influence of the radial beat and the axial motion of cylindrical shell, make the excesssive gap between stationary part and the rotating part, sealing effectiveness is bad.Another kind is contact seal, be made of with the diaphragm seal that is connected with kiln hood the sealing ring that links to each other with cylindrical shell, this sealing must outer power be pressed on diaphragm seal on the sealing ring, like this under the temperature of 300 ℃-400 ℃ of drum surfaces, diaphragm seal will soon grind, and loses sealing function.
In view of above-mentioned problems of the prior art, the purpose of this utility model is exactly will provide a kind of can make the gap between the static and dynamic sealing parts enough little, can keep seal member not do invalid wearing and tearing again, the seal of rotary kiln device that increases the service life.
Achieve the above object, the utility model realizes that by following proposal it comprises the sealing ring that is fixed on the cylindrical shell and is fixed on the sealing bar on the kiln head and tail and is contained in interior diaphragm seal, spring and the adjustment bolt of sealing bar.Its design feature is: limit, diaphragm seal two ends is parallel, and slotted hole is arranged on the diaphragm seal, and the end limit of the center line of slotted hole and diaphragm seal is parallel, and pin passes slotted hole diaphragm seal is connected with the sealing bar, forms a diaphragm seal annulus then; The adjustment ring of an off-centre is set between cylindrical shell and the sealing ring, adjusts the interior circle of ring and link to each other with cylindrical shell, cylindrical links to each other with sealing ring, and the annulus cover of being made up of diaphragm seal is pressed on the sealing ring.
The utility model compared with prior art has following advantage:
1. because pin has position-limiting action, can limit the wear extent of diaphragm seal, prolong the service life of diaphragm seal.
2. by adjusting the beat amount that ring has reduced sealing ring, good sealing effect.
3. rational in infrastructure, reliable operation, maintenance load is little.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the profile of the utility model along the cylindrical shell center line;
Fig. 2 is an A-A section partial enlarged drawing among Fig. 1;
Fig. 3 is an adjustment ring schematic diagram of the present utility model.
In the accompanying drawing: 1 cylindrical shell 2 is adjusted ring 3 sealing rings 4 diaphragm seals 5 slotted holes 6 pins 7 sealing bars 8 springs 9 and is adjusted bolt 10 kiln hoods or kiln tail 11 geometric centers 12 centres of gyration 13 end limits
Provided concrete structure of the present utility model among Fig. 1, Fig. 2, Fig. 3, it is made up of rotatory sealing parts and standstill seal parts.
Rotatory sealing parts: comprise cylindrical shell 1, adjust ring 2 and sealing ring 3.The adjustment ring 2 of an off-centre is set between cylindrical shell 1 and sealing ring 3, and circle links to each other with cylindrical shell 1 in it, and cylindrical links to each other with sealing ring 3, and interior circle is the center of circle with the geometric center 11 of cylindrical shell 1, and cylindrical is the center of circle with the centre of gyration 12 of cylindrical shell.Because adjusting the center of ring 2 cylindricals is centres of gyration 12 of cylindrical shell, so the radial beat of sealing ring 3 is very little, the beat amount can be reduced to below the 5mm.
Standstill seal parts: comprise diaphragm seal 4, pin 6, sealing bar 7, spring 8 and adjustment bolt 9.
The circle ring set of being made up of diaphragm seal is adjusted the pressure of springs 8 by adjusting bolt 9 on sealing ring 3, diaphragm seal 4 and sealing ring 3 are adjacent to.
Because differing in size of sealing ring 3 so the annulus size of forming with diaphragm seal 4 does not wait yet, according to sealing ring 3 diameters, determines the number of diaphragm seal 4.Generally can form an annulus that adapts with the sealing ring size with 3-8 diaphragm seal.
Claims (2)
