Abstract
The invention discloses a dynamic sealing device for a sintered ring cooling machine trolley, comprising a trolley, a track and an air box and being characterized in that a bracket is arranged at the outer side of a baffle at the lower part of the trolley, and the upper end of a rubber belt is fixed together with the bracket through a bolt. The rubber belt provided by the invention falls on the inner side of the baffle of the air box and clings to the inner side of the baffle of the air box by means of positive pressure formed by a high-pressure blower, therefore, the sealing effect is good, the sintering ore cooling effect is ensured, the hot air quantity is increased, and the waste heat generating capacity is improved. The dynamic sealing device is simple in maintenance due to no need of arranging two sets of sealing parts on a ring cooling machine; and in addition, the temperature resistant rubber belt, and particularly a waste and old high temperature resistant conveying belt is selected instead of an expensive fluorine rubber plate, therefore, the dynamic sealing device is low in manufacturing cost, long in service life and capable of reducing replacing and maintaining workloads.
Description
Technical field
The present invention relates to the sintering circular-cooler sealing technique, relate in particular to a kind of sintering ring cold machine trolley dynamic seal apparatus.
Background technique
Sintering deposit directly enters the sintering circular-cooler entrance after single roller fragmentation, and the sintering deposit temperature has 450 ℃～800 ℃, needs sintering circular-cooler further to be cooled to below 150 ℃, could be with Belt Conveying to blast furnace hopper.For the effective cooling sintering deposit, the sealing between sintering ring cold machine trolley both sides lower pedal and wind-box damper adopts fluorine offset plate (seeing Fig. 1 label 4) to realize, this fluorine offset plate can bear the high temperature of 200 ℃ of left and right, 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 the annular ring upper sealing cover has carried out insulation according to the requirement of cogeneration to be processed, and flue gas heat is utilized effectively.With this understanding, in equipment running process, the fluorine offset plate easy season cracking under high temperature condition originally be arranged under wind-box damper and chassis baffle plate comes off, thereby causes the part air quantity to scurry out from the gap of chassis and bellows, and sealing effect declines to a great extent, the not enough cooling effect that has affected on the one hand sintering deposit of cooling air quantity, device for generating power by waste heat, also because central cooler leaks out, causes generated energy to reduce on the other hand, also has, the sintering deposit fine particle also blows out thereupon, causes equipment dust pollution on every side.In addition, be fixed on the fluorine offset plate frequent breakage under wind-box damper and chassis baffle plate, increased maintenance cost, extended the repair time.
Summary of the invention
For above-mentioned existing problems, the purpose of this invention is to provide good seal performance, safeguard a kind of sintering ring cold machine trolley dynamic seal apparatus 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 by heatproof adhesive tape or waste and old high heat resistance conveyor belt.
Use when of the present invention, balata belt is with the circular cooler trolley circulatory motion, from the air blast of bottom, enters bellows, and the pressure of wind impels flexible rubber belt and wind-box damper naturally to be adjacent to, thereby plays dynamic sealing action, guarantees the cooling effect of sintering deposit.
Advantage of the present invention is:
1, the present invention is arranged on the chassis under shield, make balata belt can do with circular cooler trolley the circulatory motion of 360 °, and balata belt selects heatproof adhesive tape or waste and old high heat resistance conveyor belt to make, the highest ability resists the high temperature of 280 ℃ and is difficult for aging, long service life, reduced the repair and replacement workload;
2, the present invention is arranged on the chassis under shield outside, balata belt drops on the wind-box damper inboard, and the lip design forms mazy type with bellows base plate, baffle plate down and coordinates, the malleation that high pressure blower forms makes balata belt be close to the wind-box damper inboard, blast is larger, that pastes is tighter, and sealing effect is better.Guaranteed the cooling effect of sintering deposit;
3, with the supporting device for generating power by waste heat of central cooler, due to good sealing effect, increase hot blast rate, improved the cogeneration amount;
4, adopt the present invention, two cover Sealings need be set on central cooler, safeguard simply, and select the heatproof adhesive tape especially to select waste and old high heat resistance conveyor belt to substitute expensive fluorine offset plate, low cost of manufacture.
The accompanying drawing explanation
Fig. 1 provides the schematic diagram before the 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 further set forth.As shown in Figure 1, sintering circular-cooler is according to 45～80 chassis 1 of Sintering Yield scale operated by rotary motion and 12～26 bellows 2, and bellows 2 all are located on the central cooler air channel.Chassis 1 moves on track 3, the gap that exists of chassis 1 and bellows 2, under the bellows 2 baffle plate outsides and 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, thereby cause the part air quantity to scurry out from chassis 1 and the gap of bellows 2, sealing effect declines to a great extent.As shown in Figure 2, in the outside of chassis 1 under shield, be welded with support 5, support 5 adopts angle steel or channel-section steel to make, and support 5 length are pressed the under shield length of chassis 1 both sides or connection segment and determined.The plane of support 5 arranges mounting hole in impartial minute, and balata belt 6 upper ends and support 5 mounting hole corresponding positions 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 bellows 2 baffle plate inboards.For balata belt 6 is installed firmly, the most handy hole-drilled band steel is pushed down balata belt 6 and is installed, and with bolt, fixes.Balata belt 6 is selected the heatproof adhesive 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 chassis 1 both sides, circular cooler trolley 1 circulatory motion, make the bellows 2 above the central cooler air channel all seal, thereby play dynamic sealing action, guarantees the cooling effect of sintering deposit.
