Description
Technical field:
The present invention relates to a kind of sealing device for annular cooling machine.
Background technique:
Two positions of existing ring cold machine have sealing device, one be inner and outer ring sealing use sand seal, the other is wind direction with
Sealing between revolving body uses abrasive rubber.
Inner and outer ring seal aspect: in cooling machine equipment actual production, high temperature section temperature is up to 1000 DEG C, and low-temperature zone only has
100 DEG C or so, thermally conductive, heat dissipation performance is poor due to making sealing medium with fine sand between fixed petticoat pipe and revolving body, ring cold machine is every
Turn around, sand sealing groove (being made of general steel plate) will in the environment of 100~1100 DEG C hot and cold alternation continuous work, it is easy to produce
Change shape.Since hot wind permeates, sand sealing groove turns round intracorporal side steel plate by ring cold machine and first deforms, and leakproofness is poor, and hot wind leaks；
Aggravate entire sand sealing groove deformation desoldering again in turn, causes the fine sand in seal groove to be blown away by hot wind, a large amount of high-temperature hot-airs and portion
Divide hot-bulb to get into sand sealing groove, in turn results in entire sand sealing groove deformation.In addition expanding with heat and contract with cold easily causes refractory material to crack, slightly by outer
Power scraping collision can fracture, fall off.After losing refractory material protection, the fixed side panel (general steel plate production) of ring cold machine will be by
High temperature hot gas burns red oxidation, and card resistance revolving body, maintenance of being finally forced to stop production, thus caused maintenance down is very frequent, work
Amount is big, costly.
Revolving body and bellows seal aspect: conventional seals are formed by the static seal item on bellows and by squeezing between trolley
Sealing, has the following problems in actual moving process:
(1) leakproofness it is not high, 12.5 meters of slewing frame diameter, it runs on backing roll in addition, thus trolley run when, may
Can radially there be a variation, this radial irregular movement makes sealing strip and revolution at an irregular ellipse
Appearance is not periodically tight between body, so poor sealing；
(2) in the process of running, it is burnt out due to the abrasion of rubber or by high temperature pelletizing, leads to poor sealing, work as revolving body
It will lose when being greater than pelletizing diameter with the gap of bellows part.

Side, occlusion part 211, which has, keeps off grey effect.
To be easy to lift the present apparatus, lifting lug 121 is equipped on outer arc plate 12.The top of arc sealing plate 24 passes through arc
Fixed plate is fixedly connected with cover board.
To guarantee leakproofness, the fixed place of the bolt involved in the present apparatus is arranged gasket on corresponding bolt
(sealing ring) guarantees sealing effect.
Wearing plate 15 is welded on Inner arc plate 11 in sealing device in multiple sealing units 100, wearing plate 15
Position corresponds to the position of bellows in ring cold machine.
In conjunction with Fig. 7 and Fig. 8, when in use, several sealing units 100 are welded to each other and form sealing device of the present invention
It (is welding between the Inner arc plate in adjacent seals unit 100, between external arc plate, between arc sealing plate, between cover board
It is fixed), the Inner arc plate 11 in two sealing devices is individually fixed on the inside and outside wall of ring cold machine, wherein a sealing unit
100 setting intake-outlets, and automatic cycle water replanishing device is connected on intake-outlet (device is existing structure).
Sealing medium will be changed to water by the present invention, by sealing device circular water replenishing, while water level be installed in sink
Meter, when trough inner water amount is rare a certain amount of, is automatically replenished, clean-out door 4 is set on sink, and purpose overhauls sewerage for convenience,
Sludge is cleared up, simultaneously as the influence to water quality is bigger, so setting in feeding zone in discharge zone poplar ash, floating dust than more serious
The grey structure (curved baffle 21) of gear is counted.
One piece of wearing plate 15 is welded on Inner arc plate 11 in sealing device and positioned at the internal orifice of bellows two sides in ring cold machine,
So that it is arrived the diameter that the distance between revolving body is less than pelletizing, continues to be sealed with rubber strip 53 on the outside, make in the red of blanking end
Ball will not burn sealing strip, improve sealing effect.
In terms of sand seal is changed water seal by the present invention, ring cold machine sealing, cooling effect are good, and surrounding enviroment have obtained thoroughly changing
It is kind, and Stop-Time of Device Failure is reduced, and not will lead to sealing device deformation, and maintenance cost reduces.
The present invention changes the mounting structure of sealing strip, while guaranteeing leakproofness, and guarantees the intensity of sealing strip, nocuousness leakage
Wind rate is remarkably decreased, and cooling effect is obviously improved, and has prevented the red mine phenomenon of race, and economically major embodiment is in the following areas:
(1) belt deterioration declines to a great extent, and since sealing effect is good, so that sinter is fully cooled to predetermined temperature, uses belt
Period has increased significantly.
(2) seal rubber service life significantly improves, before being transformed average every 2 months will more transducer set, after transformation
Period is increased to nearly 6 months, and every heat-resisting angular sealed price of set is about 60,000 yuan, annual 20 Yu Wanyuan of save the cost.
(3) power consumption level is substantially reduced, real since 4 air blowers are predefined as out 3 for 1 before transformation, but because leaking out
Border situation is even if 4 standard-sized sheets, and cooling effect is also difficult to meet the requirements, and sealing performance improves after transformation, using opening 3 for 1
Also it is able to satisfy working condition requirement, then a motor annual consumption is 220 × 24 × 300 × 90%=1536480kw/h, by every degree electricity 1
Member is calculated, 1 year saving 150 Yu Wanyuan/year.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
It for member, can also make several improvements without departing from the principle of the present invention, these improvement also should be regarded as of the invention
Protection scope.
