Description
Technical field
The utility model relates to a kind of material screening installation of slurrying industry, relates in particular to a kind of rotary screen of suitable careless class tablet screening.
Background technology
At present, the grass as raw material deduster that the slurrying industry is used only is provided with one deck screen cloth, and because of slot size is difficult to accurately hold, it is not good that the improper dust removing effects that causes is set.Sieve aperture is too small, and part dust impurity can't be removed, and has increased follow-up burden of washing careless process; Sieve aperture is excessive, and raw material runs off with dust, causes raw material availability low, has increased production cost greatly.In addition, existing deduster can only be realized dedusting function, can not carry out classification by the tablet size, causes the tablet that obtains not of uniform size, uncontrollable qualification rate of getting the raw materials ready.In addition, problems such as solid accumulation, separative efficiency difference appear in existing rotary screen easily when work, therefore, be provided with the baffle plate of spiral continuous distributed in present also some rotary screen, though this structure has solved the problem of solid accumulation, but because material does not have the effect of external force in sieve inside, very difficult price hike is got up, and screening efficiency is low.
The utility model content
The purpose of this utility model is to provide a kind of rotary screen that is used to screen careless class tablet, and this rotary screen can effectively solve the problem of solid accumulation, and improves the efficient of screening.
For achieving the above object, the technical solution adopted in the utility model is: a kind of rotary screen, comprise main shaft and roller shelves, and main shaft one end is connected with motor by transmission mechanism, and roller shelves is wrapped with sieve plate, and described sieve plate inwall is provided with the interrupted baffle plate that distributes of spiral.Driving roller shelves when main shaft rotates rotates, tablet is got on the baffle plate under centrifugal action, under the drive of baffle plate, jumped to peak before this, after fall under gravity on the sieve plate again, because of each baffle plate in spiral distribution, can form regular pulse, tablet be screened and dedusting, effectively save power consumption by impulse action.
In the said apparatus, described main shaft circumferential hoop is wound with two-layer at least roller shelves, every layer of roller shelves all is enclosed with sieve plate outward, and the screen-aperture of each sieve plate radially diminishes from inside to outside gradually along roller shelves, between innermost layer sieve plate centre and each sieve plate is hollow structure, as material channel, each material channel tail end is equipped with material outlet.Rotation along with roller shelves, tablet arrives corresponding passage by the sieve plate in the outside step by step by size, dust arrives outermost passage by all sieve plates, realizes the dedusting and the sizing screening of tablet, obtains the tablet of corresponding size and discharges dust from material outlet.
Further, the pitch of the spiral track trace that described baffle plate distributes is 1.5～2.5m, and the big I of pitch specifically is provided with according to the length and the internal diameter of roller shelves.
Further, the helical length between the described adjacent screen is 30～100cm, and the baffle plate that is provided with can be in the separative efficiency that guarantees to improve under the unimpeded prerequisite of material material at interval.
In the said apparatus, described roller shelves is a cone barrel, and the screening area reduces gradually with the separation of material, can effectively reduce cost of manufacture.
Said apparatus also is provided with feed hopper, and feed hopper is communicated with middle material channel, is used for putting into tablet.
Said apparatus also comprises support, and described main shaft tilts to be installed on the support together with roller shelves, is convenient to material and discharges smoothly.
The utility model is provided with the interrupted baffle plate that distributes of spiral at the sieve plate inwall, forms regular pulse by baffle effect, has saved power consumption, has improved the efficient of screening.The utility model is simple in structure, and the specific yield power consumption is low, can reach the best combination of the get the raw materials ready efficient and the yield of getting the raw materials ready.
