Abstract
The invention discloses a kind of sintering ring cold machine trolley dynamic seal apparatus, comprise chassis, track, bellows, it is characterized in that, at the arranged outside support of chassis under shield, the upper end of balata belt is fixed by bolt and support.Balata belt of the present invention drops on inside wind-box damper, and the malleation that high pressure blower is formed makes balata belt be close to inside wind-box damper, and good sealing effect, ensure that the cooling effect of sintering deposit, add hot blast rate, improves cogeneration amount.Adopt the present invention, need not arrange two cover Sealings on central cooler, safeguard simple, and select thermal tape especially to select the fluorine offset plate of waste and old high heat resistance conveyor belt fictitious hosts costliness, low cost of manufacture, long service life, decreases repair and replacement workload.
Description
Technical field
The present invention relates to sintering circular-cooler sealing technique, particularly relate to a kind of sintering ring cold machine trolley dynamic seal apparatus.
Background technique
Sintering deposit directly enters sintering circular-cooler entrance after single roller fragmentation, and sintering deposit temperature has 450 DEG C ~ 800 DEG C, needs sintering circular-cooler to be cooled to less than 150 DEG C further, could with Belt Conveying to blast furnace hopper.In order to effective cooling sintering deposit, the sealing between sintering ring cold machine trolley both sides lower pedal and wind-box damper adopts fluorine offset plate (see Fig. 1 label 4) to realize, and this fluorine offset plate can bear the high temperature of about 200 DEG C, substantially can meet seal request.Along with the further propelling of China's energy-saving and emission-reduction, efforts at environmental protection, some sintering plants in succession increase flue gas waste heat power generation device on central cooler, and annular ring upper sealing cover has carried out isothermal holding according to the requirement of cogeneration, and flue gas heat is utilized effectively.With this understanding, in equipment running process, originally be arranged on fluorine offset plate under wind-box damper and chassis baffle plate under the high temperature conditions easily season cracking come off, thus cause part air quantity to scurry out from the gap of chassis and bellows, sealing effect declines to a great extent, the not enough cooling effect that have impact on sintering deposit on the one hand of cooling air quantity, device for generating power by waste heat is also because central cooler leaks out on the other hand, causes generated energy to reduce, and also has, sintering deposit fine particle also blows out thereupon, causes dust pollution around equipment.In addition, be fixed on the fluorine offset plate frequent breakage under wind-box damper and chassis baffle plate, add maintenance cost, extend the repair time.
Summary of the invention
For above-mentioned existing problems, the object of this invention is to provide good seal performance, safeguard a kind of sintering ring cold machine trolley dynamic seal apparatus that is simple, long service life.
The present invention realizes above-mentioned purpose by the following technical solutions: a kind of sintering ring cold machine trolley dynamic seal apparatus, comprise chassis, track, bellows, it is characterized in that, at the arranged outside support of chassis under shield, the upper end of balata belt is fixed by bolt and support.
Described balata belt is made up of thermal tape or waste and old high heat resistance conveyor belt.
When using of the present invention, balata belt is with circular cooler trolley circulatory motion, and the air blast from bottom enters bellows, and the pressure of wind impels flexible rubber belt and wind-box damper to be naturally adjacent to, thus plays dynamic sealing action, ensures the cooling effect of sintering deposit.
Advantage of the present invention is:
1, the present invention is arranged on chassis under shield, make balata belt can do the circulatory motion of 360 ° with circular cooler trolley, and balata belt selects thermal tape or waste and old high heat resistance conveyor belt to make, the high temperature of most high energy resistance 280 DEG C and not easily aging, long service life, decreases repair and replacement workload;
2, the present invention is arranged on outside chassis under shield, balata belt drops on inside wind-box damper, and lip design forms mazy type with bellows base plate, baffle plate down and coordinates, the malleation that high pressure blower is formed makes balata belt be close to inside wind-box damper, blast is larger, that pastes is tighter, and sealing effect is better.Ensure that the cooling effect of sintering deposit;
3, supporting with central cooler device for generating power by waste heat, due to good sealing effect, adds hot blast rate, improves cogeneration amount;
4, adopt the present invention, two cover Sealings need be set on central cooler, safeguard simple, and select thermal tape especially to select the fluorine offset plate of waste and old high heat resistance conveyor belt fictitious hosts costliness, low cost of manufacture.
Accompanying drawing explanation
Fig. 1 provides the schematic diagram before sintering ring cold machine trolley seal en-hancement.
Fig. 2 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is set forth further.As shown in Figure 1, sintering circular-cooler generally arranges 45 ~ 80 chassis 1 and 12 ~ 26 bellows 2 according to Sintering Yield scale, and bellows 2 are all located on central cooler air channel.Chassis 1 runs on the track 3, gap is there is in chassis 1 with bellows 2, outside bellows 2 baffle plate He under chassis 1 baffle plate, fluorine offset plate 4 is installed, fluorine offset plate 4 can not bear hot environment for a long time and season cracking comes off, thus causing part air quantity to scurry out from the gap of chassis 1 and bellows 2, sealing effect declines to a great extent.As shown in Figure 2, be welded with support 5 in the outside of chassis 1 under shield, support 5 adopts angle steel or channel-section steel to make, and support 5 length is pressed the under shield length of chassis 1 both sides or connection segment and determines.The plane equalization point of support 5 arranges mounting hole, and balata belt 6 upper end and support 5 mounting hole corresponding position also arrange mounting hole.The upper end of balata belt 6 is fixed by the plane of bolt and support 5, and balata belt 6 drops on inside bellows 2 baffle plate.In order to make balata belt 6 install firmly, the most handy hole-drilled band steel is pushed down balata belt 6 and is installed, and fixes with bolt.Balata belt 6 is selected thermal tape or is utilized waste and old high heat resistance conveyor belt to make.
During use, because the present invention has all been installed in every platform chassis 1 both sides, circular cooler trolley 1 circulatory motion, makes the bellows 2 above central cooler air channel all seal, thus plays dynamic sealing action, ensures the cooling effect of sintering deposit.
