Abstract
The utility model relates to a mechanical sealing device for a circular cooler. The mechanical sealing device comprises a lower sealing device and an upper sealing device, wherein the lower sealing device comprises a lower sealing pedestal, a double-plate spring, a lower slide plate; the upper sealing device comprises an upper sealing plate, an upper slide plate and a connecting plate; and a friction pair is formed by the upper sealing plate and the lower sealing plate. With slow rotation of a trolley, a sealing surface is formed via mutual sliding friction of the upper sealing plate and the lower sealing plate; and pressure of the sealing surface is provided by the double-plate spring in the lower sealing device. The beneficial effects of the mechanical sealing device are that the sealing device is simply structured with good stability and is suitable for continuous work in environments with high temperature, dust and vibration; and by the use of the mechanical sealing device, air leakage can be effectively prevented, cooling effect of the circular cooler is improved, thereby reducing energy consumption.
Description
Technical field
The utility model relates to metallurgical technology field, relates in particular to a kind of central cooler mechanically-sealing apparatus.
Background technology
Blowing circular colling machine is widely used in metallurgy industry, in particular for carrying out cooling to sintering deposit and pellet. chassis is the capital equipment of existing blowing-type central cooler, on chassis, be provided with breast board and lower breast board, under chassis, be for accepting the taper ash hopper of bulk cargo, grey hopper is stretched in lower breast board end, for reducing, leak out, need to be with the gap between breast board and ash bucket bulkhead under sealing device closed-loop cold machine trolley. the mode of the static and dynamic sealing of the inner and outer rings conventionally adopting seals, and its principle is to rely on the friction between rubber slab and steel plate to realize sealing.The conventional ring-like cooler sealed bottom of blowing-type substantially all adopts rubber seal, rubber slab adopts abrasive rubber, there is certain hardness and elasticity, owing to moving under the environment of high temperature, high dust for a long time, rubber gasket sheet easily deforms, ruptures, tears, need often to change, waste a large amount of manpowers and fund.Simultaneously more serious owing to leaking out, cause the cooling effect of sintering deposit poor, easily burn conveyor belt, it is a large amount of that to leak out to the energy be also a kind of waste.
Utility model content
The utility model provides a kind of sealing device for annular cooling machine, can effectively reduce central cooler and leak out.
The utility model comprises upper sealing device and lower sealing device two parts, is arranged on the position between chassis and ash bucket.The technical scheme adopting is: upper sealing panel and the lower seal plate friction pair that partners, and along with chassis slowly rotates, the two mutual sliding friction forms sealing surface, and the two flat springs of the pressure of sealing surface in lower seal provide.
This sealing device center line after installing is that the center of circle is the circle at central cooler center, and upper and lower slide plate center line projection overlaps, and upper and lower slide plate center line is all the concentric circles concentric with central cooler.
In this sealing device, lower seal adopts two flat spring structures, and pressure is even, Stability Analysis of Structures.The center line of two flat springs overlaps with this sealing device center line.Two flat springs, lower skateboard and lower seal base form confined space, and dust cannot enter, so lower seal is without labor cleaning, can be in long-term work under dust atmosphere, both the pressure that provided lower seal plate to need, rises again and connects lower skateboard and ash bucket, blocks the function that this part leaks out.
When central cooler is normally worked, can the phenomenons such as sideslip, chassis body or breast board distortion often occur, this device has certain adaptability.Because upper and lower sealing plate has certain width, during sideslip, upper-lower seal plate still can effectively contact.Displacement in car body or breast board generation vertical direction, sealer can dynamically be adjusted along with upper sealing panel, guarantees effective contact of upper-lower seal plate.
The curved rail of central cooler discharging does not arrange lower sealing device, and terminal is identical with the terminal of the curved rail of discharging.
The friction pair that the utility model adopts soft, hard bi-material to form carries out self-lubricating and sealing, the running statuses such as central cooler sideslip are had to certain adaptability, flat spring is except providing the thrust of sealing surface, also there is sealing function, flat spring and lower skateboard form confined space, dust enters not go, and guarantees the long-term normal work of flat spring.Be adapted at continuous operation under the environment such as high temperature, dust, vibration, device is made simple, reliable operation, and easy access and replacing, effectively reduce leaking out between circular cooler trolley and bellows, improves central cooler cooling effect, reduces energy consumption.
Accompanying drawing explanation
Fig. 1 is the utility model scheme of installation;
Fig. 2 is the local enlarged diagram of the utility model A;
Fig. 3 is the utility model lower skateboard (lower seal plate) schematic diagram;
The specific embodiment
The utility model comprises lower sealing device and upper sealing device two parts.Lower sealing device comprises lower seal base 1, two flat spring 2, lower skateboard 3, lower seal plate 4, and upper sealing device comprises upper sealing panel 5, upper slide 6, connecting plate 7, sees Fig. 1.The pressure of sealing surface is provided by two flat springs 2, after operation, also can to the pressure of sealing surface, finely tune by adjusting the lower margin spacer thickness of lower seal base 1.Connecting plate 7 tops are fixedly connected with breast board under chassis 8, and bottom is fixedly connected with slide plate 6, refers to Fig. 2.
Upper and lower slide plate is all comprised of some fan-shaped section, and between upper slide, contacting end face is flat mouth seam, and between lower skateboard, contacting end face is mismatch seam.Upper sealing panel is rectangle, and material is spheroidal graphite cast-iron, is fixedly connected with upper slide.Lower seal sheet material matter is graphite or composite graphite, and width is slightly narrower than lower skateboard, and shape is identical with lower skateboard, is fixedly connected with lower skateboard, sees Fig. 3.Upper-lower seal face is machined surface.
Upper and lower sealing plate forms friction pair, and this friction pair self lubricity is good, resistance to dry grinding.
This sealing device adopts two flat spring structures, sees Fig. 2.Two flat springs 2 are also comprised of some fan-shaped section, and segmentation is identical with lower skateboard, and coordinate installation with lower skateboard, the processing such as soft rubber skin for the gap between adjacent two boards spring 2.Two flat springs 2 one end are fastening by screw and lower seal base 1, and lower seal base 1 is connected with original ash bucket is airtight, and two flat spring 2 other ends are fastening by screw and lower skateboard.Two flat springs 2, lower skateboard 3 and lower seal base 1 form confined space, and dust cannot enter, without labor cleaning.
The foregoing is only the utility model preferred embodiments, not in order to limit the utility model, all any modification, replacement and improvement etc. of making within spirit of the present utility model and principle, within all should being included in protection domain of the present utility model.
