Abstract
The utility model discloses a labyrinth gland of an annular cooler. A first vertical seal plate and a second vertical seal plate are fixedly arranged on edges of two sides of an air bellow from inside to outside, and a horizontal seal plate transversely penetrating through the first vertical seal plate and the second vertical seal plate is further arranged; a first seal plate and a second seal plate are arranged below two sides of a rotary trolley from inside to outside; the first seal plate is arranged in a gap between the first vertical seal plate and the second vertical seal plate, and the second seal plate is arranged on the outer side of the second vertical seal plate; and the lower ends of the first seal plate and the second seal plate are tightly attached to the upper surface of the horizontal seal plate. According to the utility model, safe and reliable excellent equipment is provided; under the gradual pressure reduction action of a labyrinth formed by the labyrinth device adopting rubber sealing, negative influence on a static seal plate in the prior art due to the position error and the mounting error caused by rotary body deformation is completely prevented; and the labyrinth gland of the annular cooler has high reliability, long service life and good economic benefits.
Description
Technical field
The utility model relates to a kind of labyrinth gland for sealing between central cooler revolving body and bellows.
Background technology
In current sealing device of sintering circular cooler, using more is a kind ofly to adopt dynamic and static twice rubber slab as sealing device.As shown in Figure 3, mainly turn round by being installed on the dynamic sealing rubber plate 9 moving with revolution chassis 1 in bottom, the static seal rubber slab 7 being installed on fixed mount 8 forms.Described dynamic sealing rubber plate, static seal rubber slab are not revealed to outside in order to guarantee the cold air with pressure bloating from bellows.In theory, the lateral relationships of described static seal rubber slab and revolution chassis and slewing frame (from Fig. 3 in A direction) as shown in Figure 4.But in use find, sintering circular-cooler is filling hot ore deposit in progressively cooling process, the distortion that revolving body is produced because of thermic load is larger, adds the error in manufacture and installation process, causes central cooler to produce certain error in the process of turning round return after chassis discharging.Before and after, between chassis, have the discrepancy in elevation, also there is the discrepancy in elevation in chassis and slewing frame, as the aa in Fig. 5 and bb place.The steel plate at this discrepancy in elevation place moves, the directly hard-wired static seal rubber slab of cutting,, cause the damage completely of static seal, have influence on service life.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of central cooler labyrinth gland, has solved the air leak rate of air curtain occurring in central cooler seal process high, the problem that service life is short.
For achieving the above object, a kind of central cooler labyrinth gland described in the utility model, respectively be fixedly installed from inside to outside the first vertical seal plate, the second vertical seal plate in bellows both sides of the edge, a horizontal seal plate that is horizontally through described the first vertical seal plate and described the second vertical seal plate is also set; Down either side at revolution chassis is respectively provided with the first sealing plate, the second sealing plate from inside to outside; Described the first sealing plate is placed in the gap between described the first vertical seal plate and described the second vertical seal plate, and described the second sealing plate is placed in the outside of the second vertical seal plate; The lower end of described the first sealing plate and the second sealing plate is all adjacent to the upper surface of horizontal seal plate.
Preferably, the upper end of described the first vertical seal plate bends laterally; The upper end of described the second vertical seal plate bends to the inside.
Preferably, described the first sealing plate and the second sealing plate are rubber slab.
The beneficial effects of the utility model are:
The utility model provides a kind of safe and reliable good equipment.It utilizes maze device to add rubber seal and forms the decompression step by step effect in labyrinth, site error and the adverse effect of alignment error to static seal plate in prior art avoiding revolving body to be out of shape completely causing.There is high reliability and service life, and good economic benefit.
Accompanying drawing explanation
Fig. 1 is the principle schematic of central cooler labyrinth gland described in the utility model embodiment;
Fig. 2 is the enlarged drawing of II in Fig. 1;
Fig. 3 is the structural representation of existing central cooler obturator;
Fig. 4 is the theoretical effect figure in A direction in Fig. 3;
Fig. 5 is the actual effect figure in A direction in Fig. 3.
The specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
As Figure 1-Figure 2, a kind of central cooler labyrinth gland described in the utility model embodiment, respectively be fixedly installed from inside to outside the first vertical seal plate 4, the second vertical seal plate 5 in bellows both sides of the edge, a horizontal seal plate 6 that is horizontally through described the first vertical seal plate and described the second vertical seal plate is also set.Wherein, the upper end of described the first vertical seal plate bends laterally; The upper end of described the second vertical seal plate bends to the inside.
Down either side at revolution chassis 1 is respectively provided with the first sealing plate 2, the second sealing plate 3 that adopt quality of rubber materials from inside to outside; Described the first sealing plate is placed in the gap between described the first vertical seal plate and described the second vertical seal plate, and described the second sealing plate is placed in the outside of the second vertical seal plate; The lower end of described the first sealing plate and the second sealing plate is all adjacent to the upper surface of horizontal seal plate.
In the drawings, described the first vertical seal plate, horizontal seal plate and the first sealing plate form space A, described the first sealing plate, horizontal seal plate and the second vertical seal plate form space B, and described the second vertical seal plate, horizontal seal plate and the second sealing plate form space C.
Operation principle of the present utility model is:
In the time that bellows exit blast is P0, because pressure after having stopping of the first vertical seal plate to enter A space is reduced to P1, the first sealing plate is close to horizontal seal plate, after the air leaking out from the first sealing plate gap so enters into B space, its pressure will greatly be reduced to P2, due to the stopping of the second vertical seal plate, air enters behind C space again, and its pressure will continue to be reduced to P3, finally, due to the stopping of the second sealing plate, air leak is by very little.Thereby reach the object of positiver sealing.In addition, because the horizontal seal plate contacting with the first sealing plate, the second sealing plate is static installation, as long as guarantee its smooth situation that just there will not be cutting the first sealing plate, the second sealing plate, the service life that has strengthened sealing device while installation.
Above; it is only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
