Description
Technical field
The present invention relates to bolter equipment, especially a kind of coal dust classifier that traps the fiber that adulterates in coal dust.
Background technology
In coal gasifying process, much technique needs first raw coal to be worn into coal dust, then sends into gasification furnace by burner and gasifies.Due to reasons such as raw coal and transportation storages, in the coal dust grinding, be mixed with fiber different in size, easily block Pneumatic conveying pipeline or in burner place bonding, affect the operation of system long-term stability.At present, conventional coal dust separation equipment generally all adopts lattice structure, can effectively sift out fiber, can improve the purity of coal dust, improves the result of use of coal dust.But the coal dust classifier of lattice structure can only sift out a small amount of short fiber and velvet-like fiber, can not thoroughly solve jet hole and be glued problem stifled and scaling loss.
Patent CN101322968A discloses a kind of coal fines fiber separator, comprise drive unit, comb filter structure and shell, comb filter structure is take runner as frame member, be fixedly connected with the comb thorn bar that is radial arrangement in runner upper surface, its lower surface is fixedly connected with sieve shape grid, grid is the circular sieve plate of combined type, wait piecemeal to form by 3～5, comb thorn bar is strip member, arrange the comb thorn of needle-like at interval of 3.5～4.5mm towards upper surface length direction, comb thorn diameter 2～3mm, long 50～the 75mm of comb thorn, comb thorn on comb thorn bar is towards 10 °～15 ° arrangements of direction of rotation inclination.When the rotation of comb filter structure; first the comb thorn with 10 °～15 ° of angles of lead carries out combing to coal dust; the long fibre combing out slides to comb thorn root along angle of lead; grid sifts out short fiber and the velvet-like fiber that comb thorn does not clear out; once the accumulation of fibers of comb filter structure comb filter, to set amount, is removed from clean-up port after shutdown.Comb thorn combing and grid screen double-layer separating structure that the upper and lower end face of this comb filter structure sets up separately are synchronous rotary, are easy to stop up, and stop up once local; be easy to spread to whole cross section; above grid, pile with coal dust, kill drive unit, cause Whole Equipment to shut down.Increased greatly maintenance worker's labour intensity, the system that simultaneously affects is normally moved, especially comb thorn surface smoothing, the long fibre that combing goes out is sliding to after comb thorn root, due to the impact of coal dust and the multiple action of rotational structure, be easy to separate with combing thorn, again sneak in coal dust.Agglomerating fiber is easy to stop up grid, causes fault, and comb thorn bar is radial arrangement, is difficult to fully contact with coal dust, and purification efficiency is low.
The coal fines fiber separator of prior art exists that screening capacity is weak, grid easily blocks, combs the shortcomings such as filter structure failure height, and the system that affects is normally moved.
Summary of the invention

The concrete technical scheme that realizes the object of the invention is: a kind of coal dust classifier, comprise rotating mechanism, comb filter structure and housing, housing is beveled cone, its top cover is provided with charging aperture, bottom is provided with discharging opening, rotating mechanism is made up of motor and speed reducer, reductor is fixedly installed on the top cover of housing, its power shaft is connected with motor, output shaft is connected with the rotating shaft that is arranged on the comb filter structure in housing, be characterized in that described comb filter structure is by the runner that is provided with comb row, differential speed transducer and filter screen rotating disk composition, runner and filter screen rotating disk are upper, lower floor arranges, differential speed transducer is arranged on runner with filter screen rotating disk centre and is coaxial connection with runner and filter screen rotating disk, described comb row is arranged in parallel or " Z " shape is arranged between the spoke of runner for equidistant, comb row with runner for being fixedly connected with, in described housing, be provided with the bracket that supports runner and filter screen rotating disk, bracket and runner and filter screen rotating disk are for being slidably connected, and bracket and housing are welding, described speed reducer output shaft is connected with the wheel shaft of runner, and runner is by differential speed transducer band electric filter rotating disk differential speed rotation in the same way.
In described housing, be provided with nitrogen jet pipe, housing is provided with steam pipe coil outward, and nitrogen jet pipe is fixedly installed on filter screen rotating disk top.
Described comb row's broach is provided with hangnail, and comb tooth spacing is 10～20mm.
The trapping ability that the present invention has coal dust fiber is compared with prior art strong, and purification efficiency is high, and explosion-proof performance is good, and filter screen is difficult for stopping up, and simple in structure, operation, easy to maintenance, reliable operation, the service life of having improved equipment.
