Abstract
A secondary slag transport manner changes the slag transport direction via a secondary slag transporter, a primary head part is connected with a secondary tail part, a primary steel strip and a cleaning chain are higher than a secondary steel strip, and the slag is put on the secondary steel strip. A slag trap is arranged at the primary head part to prevent the slag from being sucked to the underside of the primary steel strip by the negative pressure in a furnace during the slag falling process from the primary stage to the secondary stage.
Description
Technical field
The utility model relates to the equipment of slagging tap of power plant boiler, and the air-cooled dry type mucking machine of particularly a kind of secondary that can turn to belongs to mechanical field.
Background technology
Existing thermal power plant furnace bottom is slagged tap and is mostly adopted waterpower to drag for slag, not only causes the waste of water resource, and the heat of lime-ash also wasted, and production environment is unfavorable for carrying out production strictly in line with rules and regulations, and air-cooled dry type mucking machine has then solved the problems that waterpower is dragged for slag.It is that lime-ash is after water cooling that waterpower is dragged for slag, scrape in the trench by dragveyer, water is flushed in the outer ashpit of factory building and goes, and air-cooled dry type mucking machine is that 800-900 ℃ of lime-ash dropped on the steel band, while walking, and then carry or mechanical mode of movement is transported in the outer slag storehouse of factory building and goes by strength with natural wind cooling.Over the past two years, newly-built unit has all adopted the dry type mucking machine, but concerning old power plant, because the arrangement requirement of air-cooled dry type mucking machine is not considered in former design, the scene is all less than doing subsequent treatment than large space, and the dry type mucking machine is the same with dragveyer, is to go out factory building along outer, the furnace bottom left and right sides, and is just more longer, it is big many to take up room than the waterpower dragveyer, this dry type equipment of slagging tap have equipment or other reasons just to be not easy to transform as both sides, so can not be adopted in many scenes.
Adopt the secondary break-in to carry and to solve this scene problem preferably, but bring the other problem thereupon.In the boiler that uses at present, except that combined-circulation once-through boiler, the boiler of many power plant all is negative-pressure firings, in one-level in the secondary transfer process, many thin ashes are drawn onto the steel wire the inside of one-level steel band by negative pressure, make steel band sideslip in rotating walking process, dust stratification has also increased the burden of cleaning chain below the steel band simultaneously, causes serious wear even breaks.
Summary of the invention
The utility model provides a kind of air-cooled dry type mucking machine of the secondary that can turn to that can change the lime-ash throughput direction, can solve lime-ash is sucked back the one-level bottom by negative pressure problem.Technical scheme is as follows: the air-cooled dry type mucking machine of a kind of secondary that can turn to, it is characterized in that being provided with the defeated slag conveyer belt of two-stage, be the sealing endless belt, one-level head and secondary afterbody are end to end, be provided with angle between the two-stage, be provided with slag trap in the one-level lower head, be blocked in the negative pressure suction inlet between one-level conveyer belt and the one-level mucking machine housing bottom surface.The below of the defeated slag conveyer belt of two-stage all can be provided with and the parallel cleaning chain of conveyer belt separately, be the sealing loop chain, the cleaning chain length is shorter than conveyer belt, the cleaning chain contains driving chain and is fixed on the scraper plate of advancing synchronously on the chain, respectively the bottom surface of two-stage mucking machine housing under the scraper plate, sliding-contact between the bottom surface of scraper plate and housing, one-level cleaning chain is higher than the secondary conveyer belt.The place ahead of slag trap also can be provided with deflector.
Advantage of the present utility model and effect: adopt the defeated slag mode of secondary, change defeated slag direction by the secondary slag conveyer, the below of the defeated slag conveyer belt of two-stage is equipped with the belt scraping plate parallel with conveyer belt separately and cleans chain, the one-level head links to each other with the secondary afterbody, one-level conveyer belt and cleaning chain are higher than the secondary steel band, and ash is put on the secondary steel band.Be provided with slag trap, deflector at the one-level head, prevent from one-level to secondary falls the slag process by stove in negative pressure suck back below the one-level conveyer belt.
