Description
Technical field
The utility model relates to a kind of screening plant of granule materials, and in particular, the utility model relates to a kind of drum sieve with automatically cleaning structure.
Background technology
Drum sieve is the screening plant that is widely used in industries such as thermal power generation, mine, cement, building materials at present.In the use of multiple drum sieve,, cause material to be bonded on the sieve castor usually because the water content of the material that sieves is big or the high humidity of thin material, when adhesive many time, just stop up sieve aperture, made sieve aperture obstructed, caused the decline of screening efficiency or situation about can't sieve., because the restriction of objective condition, the water capacity of material all exists greatly under many circumstances.So, sieve pore blockade in various degree just become drum sieve use in not only ubiquity, but also can't avoid, and influence the subject matter of the normal operation of equipment simultaneously.In order to address this problem, in service at screening plant often needs to clear up sieve aperture continually, and this cleaning work unusual trouble not only, and effect is unsatisfactory.
The utility model content
The purpose of this utility model solves the defective that above prior art exists exactly, thereby provides a kind of sieve pore blockade of can avoiding to save the sieve aperture cleaning work, thereby the drum sieve with self-cleaning mechanism that material screening efficient is improved.
The utlity model has the drum sieve of self-cleaning mechanism, comprise the upper casing that is provided with charging aperture and be provided with the lower casing that coarse fodder exports, fines exports, described upper and lower casing is fastened and connected by flange and the main framing that is provided with between its faucal; One end of described main framing is set with motor and reductor, and the output shaft of described reductor connects the main shaft that runs through described upper casing housing by shaft coupling, and described main shaft is provided with the cartridge type sieve nest; The top of described cartridge type sieve nest is provided with the spread pen formula wire brush that connects governor motion.
The mode that sieve aperture on the described cartridge type sieve nest is dredged with close, the circumferential spacing of axial spacing is provided with.
Described governor motion comprises pedestal that connects abase frame and the adjustable plate that is connected described pedestal by bolt, and described adjustable plate is provided with horizontal adjustment bolt and vertical adjusting bolt, and the lower end of described adjustable plate is provided with swinging axle.
Described spread pen formula wire brush is made of link plate, hair brushing plate and bristle, the upper end of described link plate connects described adjustable plate by described swinging axle, the lower end of described link plate is provided with hair brushing plate, described bristle is fixed by described hair brushing plate, and the two ends of described hair brushing plate connect the arm-tie that is arranged on described abase frame both sides by spring respectively.
Apart from setting, and each bristle individuality is at each sieve aperture on the described cartridge type sieve nest according to the axial hole that constitutes sieve aperture on the described cartridge type sieve nest in the bristle position of described spread pen formula wire brush.
The bristle of described spread pen formula wire brush is made of rod iron or steel tendon.
The beneficial effects of the utility model are: because the setting of described spread pen formula wire brush, sieve pore blockade and the frequent problem of clearing up of needs that the drum sieve that has solved prior art is in operation and forms, so, no matter the humidity of the water content of the material that sieves or thin material is much, can not cause material to be bonded on the sieve aperture, therefore, the main disadvantage of the normal operation of equipment can't be avoided, also be influenced simultaneously to the situation of effectively having avoided the obstructed screening efficiency that causes of sieve aperture to descend and maybe can't sieve material, the drum sieve ubiquity that has overcome prior art again.
