The sliding plate type sealing device is safe and reliable; the air leakage is avoided; the sliding plate type sealing device is long in service life; after a sintering machine adopts the sealing device, the current of a main exhaust fan can be reduced by 15%; the negative pressure of a tail air box is increased by 50%; the consumption of solid fuel and the sinter return rate are obviously reduced; the cost of the sintered ore is reduced.
Description
Technical field
The present invention relates to sintering machine technical field, be specifically related to slide type sealing device.
Background technology
What sintering machine slide way sealing was the most commonly used is that slide type seals, and seals and is divided into two parts, one
Dividing the elastic trip plate being mounted on chassis, another part is integrally fixed at the slide plate on bellows, and chassis is in fortune
In row, chassis trip plate forms matched in clearance with slide plate, and in gap, charging-up lubricant oil fat seals and moistens
Sliding；Sintering machine is after running after a while, and in running due to chassis, head is relatively big to tail variations in temperature,
Head bellows temperature is by about 75 DEG C, and tail box temperature reaches about 450 DEG C, causes trip plate deformation, bullet
Spring follows the string and makes slideway seal and lose sealing effectiveness, and in sintering machine running, substantial amounts of
Dust is entered bellows by grid section at the bottom of chassis, as easy as rolling off a log causes between upstream plate and lower skateboard partial lubrication blocking,
Cause slideway wear and tear overrun to cause to leak out, sintering machine running deviation, also result in trip plate and be combined with slideway bad,
Causing gap to increase, cause increase of leaking out, slideway of sintering pallet sealing effectiveness is poor, will result in sintering
System air leakage amount increases, and main exhauster power consumption increases, and Sintering Yield, Quality Down, on production cost
Rise.
Summary of the invention
It is an object of the invention to provide slide type sealing device, solve in above-mentioned prior art problem or
Person is multiple.
According to the sliding slide type sealing device of the present invention, including trolley body, it is installed on below described trolley body
Bellows, the trip plate being fixed on described trolley body and the slide plate be located on described bellows, described trip plate with
Described slide plate slides connects, and described trip board is embedded on described trolley body, passes through between trip plate and trolley body
Fixing bolt is fixing to be connected, and is connected with fixed block, is provided with oil pipe passage in described fixed block under slide plate,
Described oil pipe passage is through described slide plate.
Slide type sealing device provided by the present invention, safe and reliable, prevent from leaking out, service life is long,
After sintering machine uses this sealing device, main exhauster electric current can decline 15%, and the negative pressure of afterbody bellows increases
50%, solid fuel consumption and the rate of return mine are all decreased obviously, and reduce the cost of sintering deposit.
In some embodiments, the trapezoidal structure in described bellows cross section, described bellows pass through with fixed block
Bolt is affixed.
In some embodiments, rubber layer has been flexibly connected between described fixed block and described bellows.Rubber
Glue-line is high-temperature resistant rubber, prevents chassis to be in operation generation sideslip, flexibly connecting by rubber layer,
When sintering machine runs, chassis sideslip, trip plate can drive slide plate to run along the track of chassis together, make trip plate
All the time combine with slide plate, keep good sealing state.
Accompanying drawing explanation
Fig. 1 is the structural representation of the slide type sealing device of one embodiment of the present invention.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention is described in more detail.
As it is shown in figure 1, slide type sealing device, including trolley body 1, it is installed on below trolley body 1
Bellows 2, the trip plate 3 being bolted to connection on trolley body 1 and the slide plate 4 being installed on bellows 2；
It is slidably connected between trip plate 3 and slide plate 4, solid by welding manner or bolt fixed mode below slide plate 4
Surely fixed block 5, fixed block is had to be connected with bellows 2 by bolt 5 times, the trapezoidal shape of sectional area of bellows 2,
Fixed block 5 is installed and can dismantle bellows 2 eaily, it is simple to the maintenance of bellows 2, use easily,
It is equipped with oil pipe passage 6 in fixed block 5, and oil pipe passage 6 communicates with slide plate 4, can be by oil
Tube passage 6 provides oils and fats to slide plate 4, serves the effect of lubrication.
Having flexibly connected rubber layer between fixed block 5 and bellows 2, rubber layer is high-temperature resistant rubber, prevents
Chassis is in operation generation sideslip, flexibly connecting by rubber layer, when sintering machine runs, and trolley body 1
Sideslip, trip plate 3 can drive slide plate 4 to run along the track of trolley body 1 together, make trip plate 3 and slide plate 4
All the time combine, keep good sealing state.
The present invention utilizes flexible connected slide plate 4 on bellows 2 to carry out convex with the trip plate 3 on trolley body 1
Recessed assembling, centre oils and fats seals and lubricates, and plays labyrinth sealed effect, greatly reduces
Sintering machine leaks out；Even if trip plate 3 and slide plate 4 have deformation and abrasion, labyrinth sealing still will not be subject to
Impact, will not leak out, and the slide plate 4 on bellows 2 carries out flexible connection with bellows 2 high-temperature resistant rubber
Connect, solve the impact that sintering machine running deviation can bring, make the sealing device can be actual along transfer table body of sintering engine 1
Running orbit automatically adjusts, and keeps not leaking out, and the design of head arc skateboard solves turns over from loop
Turn the chassis come up and can enter groove smoothly, it is ensured that sealing effectiveness.
Slide type sealing device provided by the present invention, safe and reliable, prevent from leaking out, service life is long,
After sintering machine uses this sealing device, main exhauster electric current can decline 15%, and the negative pressure of afterbody bellows increases
50%, solid fuel consumption and the rate of return mine are all decreased obviously, and reduce the cost of sintering deposit.
Slide type sealing device provided by the present invention, simple in construction, the most easy to wear, good sealing effect,
Cover plate is unlikely to deform, and maintenance simplicity, and maintenance cost is little.
The above is only the optimal way of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, it is also possible to make some similar deformation and change
Enter, within these also should be regarded as protection scope of the present invention.
