Technical field
The present invention relates to a kind of material screening installation of slurrying industry, relate in particular to a kind of tablet classification dust arrester that is used for careless class tablet sizing 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.
Summary of the invention
The object of the present invention is to provide a kind of tablet classification dust arrester that is used for careless class tablet sizing screening, can carry out dedusting and classification to tablet simultaneously, effectively improved raw material availability.
For achieving the above object, the technical solution used in the present invention is: a kind of tablet classification dust arrester, comprise main shaft and roller shelves, main shaft one end is connected with motor by transmission mechanism, and described main shaft circumferential hoop is wound with two-layer at least roller shelves, and 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, and as material channel, each material channel tail end is equipped with material outlet.Driving roller shelves when main shaft rotates rotates, tablet is got on the sieve plate under centrifugal action, arrive corresponding passage by the sieve plate in the outside step by step by size, dust arrives outermost passage by all sieve plates, realize the dedusting and the sizing screening of tablet, obtain the tablet of corresponding size and discharge dust from material outlet.
In the said apparatus, in each sieve plate at least innermost layer sieve plate inwall be provided with the interrupted baffle plate that distributes of spiral, under baffle effect, material can form regular pulse, carries out classification by impulse action, has saved power consumption, has improved screening effect.
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.The cone angle of cone barrel roller shelves can specifically be provided with according to the material impurity content, and it is more little that the many more cone angles of impurity can be provided with, and guarantees that this equipment has higher dust removal efficiency, and is concrete, and the cone angle of described roller shelves is 8 °～12 °.
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.
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, described main shaft and roller shelves tilt to be installed on the support, for ease of smooth discharge, generally need to guarantee that described roller shelves bottom surface and installed surface angle are 5 °, then corresponding to the cone angle size of roller shelves, the angle of described main shaft and installed surface is 9 °～11 °.
The present invention can realize the dedusting and the classification of tablet simultaneously by the different sieve plate of multi-deck screen hole size is set, and at the sieve plate inwall the interrupted baffle plate that distributes of spiral is set, and forms regular pulse by baffle effect, has saved power consumption, has improved the effect of classification.The present invention 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.
