Abstract
The utility model discloses an annular ring upper sealing device, which mainly comprises an upper flat plate, an upper ribbed plate, a lower flat plate, a lower ribbed plate, a heat insulation plate and a rubber sealing plate. A fixed plate arranged vertically is fixedly connected on the upper flat plate and the upper ribbed plate, a bevel plate arranged obliquely is fixedly connected to the lower flat plate and the lower ribbed plate, the rubber sealing plate is fixedly connected to the fixed plate, the lower portion of the rubber sealing plate is attached onto the outer end face of the inclined plate closely, the heat insulation plate is arranged between the fixed plate and the rubber sealing plate, and the upper end of the bevel plate is superposed with the lower end of the heat insulation plate horizontally. After being damaged, the heat insulation plate and the rubber sealing plate of the annular ring upper sealing device can be changed outside a sealing cover conveniently and safely, radiation of hot sinter ores can be shielded thoroughly by coaction of the heat insulation plate and the bevel plate, and accordingly the service life of the rubber sealing plate is prolonged while air leakage can be reduced effectively.
Description
Technical field
The utility model relates to a kind of sealing device of central cooler, especially a kind of central cooler top seal device.
Background technology
Central cooler mainly is made up of the charge chute of motion and the chassis and the bellows of its underpart, accepts heat sinter at the material feeding point, by the past heat sinter air blast of bellows, sintering deposit is cooled off in running.Rubescent heat sinter temperature up to 750 degree about, the hot blast temperature by the thermal sintering ore bed reaches 400 more and spends, and is the good thermal source of waste heat recovery.And during by seal closure suction hot blast, will suck cold wind between its seal closure and the charge chute.This has not only reduced hot blast temperature, has reduced the efficient of waste heat recovery, and has reduced the air quantity by the thermal sintering ore bed, can't guarantee cooling effect.
As shown in Figure 1, existing central cooler top seal device adopt vertically disposed rubber gasket sheet and the seal outside face directly contact and seal, by being installed in vertically disposed thermal insulation board isolation heat radiation under the seal closure.There is following defective in such structure: 1, thermal insulation board is installed in the seal closure of central cooler, it is very inconvenient to install and change, must utilize the stop production to overhaul time to creep into bellows inside just can finish, and be absolutely unsafe, in case thermal insulation board damages, just can finish replacing when stop production to overhaul such as having only, cause it to perform practically no function in process of production; 2, thermal insulation board must leave one section height of seal, is difficult to play the thermal-radiating effect of effective partition, and rubber gasket sheet is easily by roasting bad, shortened the life-span of rubber gasket sheet, will cause in a large number as untimely replacing and to leak out,, also cause the spare part expense to raise even change in time; 3, rubber gasket sheet to face the sealing effectiveness of sealing means own directly relatively poor, the result who leaks out has in a large number reduced about 20 degree of hot blast temperature, directly reduces waste heat recovery efficient about 5%.
Summary of the invention
The utility model provides a kind of good sealing effect for the deficiency that solves above-mentioned technology, can effectively reduce inleakage and prolong the rubber gasket sheet life-span central cooler top seal device.
In order to achieve the above object, the central cooler top seal device that the utility model is designed, it mainly comprises upper flat plate, last gusset, following dull and stereotyped, lower web plate, thermal insulation board and rubber gasket sheet, be fixedly connected with a vertically disposed fixed head on described upper flat plate and the last gusset, on described flat board down and lower web plate, be fixedly connected with a swash plate that is obliquely installed, described rubber gasket sheet is fixedly connected on the fixed head, and the bottom of this rubber gasket sheet fits tightly on the outer face of described swash plate, described thermal insulation board is arranged between fixed head and the rubber gasket sheet, and the upper end of described swash plate and the lower end of thermal insulation board are overlapping in the horizontal direction.
As preferably, the upper end of described swash plate is higher than dull and stereotyped down and is in down between the flat board and upper flat plate.
As preferably, the part of fitting in the outer face of described rubber gasket sheet and swash plate is provided with elongated slot.
As preferably, described rubber gasket sheet is fixedly connected on the fixed head by wedge block and chock, is provided with pressing plate between chock and rubber gasket sheet.
The central cooler top seal device that the utility model obtains has following advantage:
1, after thermal insulation board and the rubber gasket sheet breakage, can in time obtain easily in the outside of seal closure installing and change, and safe;
2, the lower end of the upper end of swash plate and thermal insulation board is overlapping in the horizontal direction, acting in conjunction by thermal insulation board and swash plate, the radiation of heat sinter is thoroughly cut off, the situation of having avoided rubber gasket sheet to be burnt out, can effectively prolong the service life of rubber gasket sheet, reduce the consumption of rubber gasket sheet;
3, rubber gasket sheet can effectively strengthen sealing area, and sealing effectiveness is better, can effectively reduce and leak out;
4, the design of rubber gasket sheet bottom elongated slot not only makes the easy bending of rubber gasket sheet, assurance rubber gasket sheet contact with swash plate, and form labyrinth sealing on sealing surface, when having strengthened sealing effectiveness, has reduced frictional resistance;
Comprehensive function can reduce air leak rate of air curtain more than 3%, improves waste heat recovery efficient 4%.
Description of drawings
Fig. 1 is the structural representation of existing central cooler top seal device;
Fig. 2 is the structural representation of embodiment 1;
Fig. 3 is the structural representation of embodiment 2.
Among the figure: swash plate 1, down dull and stereotyped 2, upper flat plate 3, go up gusset 4,, thermal insulation board 5, fixed head 6, lower web plate 7, wedge block 8, chock 9, pressing plate 10, rubber gasket sheet 11, elongated slot 12.
The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 2, the described central cooler top seal of present embodiment device, it mainly comprises upper flat plate 3, last gusset 4, following dull and stereotyped 2, lower web plate 7, thermal insulation board 5 and rubber gasket sheet 11, be fixedly connected with a vertically disposed fixed head 6 on upper flat plate 3 and the last gusset 4, be fixedly connected with a swash plate that is obliquely installed 1 on flat board 2 and the lower web plate 7 down, rubber gasket sheet 11 is fixedly connected on the fixed head 6, and the bottom of this rubber gasket sheet 11 fits tightly on the outer face of swash plate 1, thermal insulation board 5 is arranged between fixed head 6 and the rubber gasket sheet 11, the upper end of swash plate 1 is higher than following flat board 2 and is between following flat board 2 and the upper flat plate 3, and the lower end of the upper end of swash plate 1 and thermal insulation board 5 is overlapping in the horizontal direction.
