Description
Technical field
The utility model relates to the sinter cooler field, relates in particular to the sealing device between a kind of chassis and the last seal closure.
Background technology
At present; Sintering deposit burns till the back and gets into cooler on sintering machine; That cooler is with is cold, the ring is cold, three kinds of coolings on the machine, and the above two cooling means mainly are to adopt the air blast cooling, and the hot ore deposit temperature of this moment has 700-800 ℃; Under the effect of air blast or air-introduced machine, make cold air pass hot ore bed hot ore deposit is cooled off behind the entering cooler.There is 1-3 seal closure the charging chassis top of general belt-cooling machine, central cooler, and the waste gas in heat of cooling ore deposit gathers through the chimney emptying through seal closure.
Owing to assembly precision and equipment temperature distortion reason; Have the gap between general chassis and the last seal closure, less clearance has 10-20mm, and bigger gap reaches more than the 100mm; Like this under the not smooth situation of chimney emission; Form pressure-fired in the petticoat pipe, a large amount of flue dust directly is discharged on the sinter cooler scope of operation through the gap, and operating environment is sharply worsened.
Popularization along with the energy-saving and emission-reduction project; Increasing sintering machine waste heat project has been equipped with the cooler hot air circulating system; Through air-introduced machine 350 ℃ hot blast in the cooler seal closure is extracted to the machine the thermal source as waste heat boiler; To utilize remaining about the 150 ℃ low-quality hot blast in back to rouse go back to bellows continuation heat of cooling ore deposit under the cooler again, thereby improve the temperature of boiler inlet hot blast, make it to reach 410 ℃ nearly.Because the gap between sinter cooler and the last seal closure exists; When the negative pressure that in the air-introduced machine exhausting, forms reaches 100Pa; A large amount of cold wind sees through the gap and gets into seal closure; With the flue-gas temperature that greatly reduces the waste heat boiler import after high-temperature flue gas mixes, have a strong impact on the steam production and the quality of waste heat boiler.
The sintering machine cooler is higher at the bellows blast of pallet bottom; Reach 3000-4000Pa; Therefore between chassis and bellows, generally all be provided with sealing device, but between chassis upper limb and last seal closure, do not adopt sealing device, also have the sintering machine of minority supporting steel disc or rubber seal; Steel disc is owing to be to be rigidly connected, and the leakage of flue gas is more serious.And rubber seal sealing effectiveness when just using is better, but after long work, receives the high temperature melting rubber part damaged, needs often to change, and can only when parking maintenance, carry out owing to changing, so can't fundamentally solve sealing problem.
Summary of the invention
The purpose of the utility model is the defective that exists to prior art, and the sealing device between a kind of chassis and the last seal closure is provided, and satisfies the seal request between chassis and the last seal closure, uses reliable, easy for installation, for ease of maintenaince simultaneously.
The technical scheme summary of the utility model:
Sealing device between chassis and the last seal closure; Comprise coaming plate, water proof baffle plate and mobile water seal, an end of last coaming plate links to each other with last seal closure lower edge, and the other end of last coaming plate bends to cell body; Be provided with mobile water seal in the cell body, it is 150-300mm that said cell body bottom is lower than chassis upper edge H; One end of said water proof baffle plate is connected with the chassis upper edge, and the other end of water proof baffle plate bending downwards stretches in the mobile water seal of cell body; Said cell body is provided with water inlet pipe and drainpipe, and drainpipe links to each other with water inlet pipe through circular water treating system.
Said circular water treating system comprises that sedimentation basin, filter, cistern, water pump link to each other successively, filter and filter sand cleaning device, and cistern links to each other with filling pipe, and drainpipe links to each other with sedimentation basin, and water pump links to each other with water inlet pipe.
Compared with prior art, the beneficial effect of the utility model is: do not influence the structure of original sinter cooler, system is reliable; Seal degree is higher, can satisfy the seal request between chassis and the last seal closure fully, and is simultaneously easy for installation, for ease of maintenaince; But Fast Installation and dismounting; Operation principle is simple, and part of appliance is less, can realize the maintenance that do not stop production.
