Description

A kind of pill seed-coating machine

Technical field

This utility model relates to a kind of pill seed-coating machine.

Background technology

In current prior art; the pill Granulation Equipments can adopt centrifugal spheronization usually; material particles is on a rotating disk; rotating disk is in high speed rotating, and material particles is got rid of to barrel by centrifugal action, and rotating disk and barrel have a fine clearance; its bottom passes to the pure air of certain pressure; stop material particles to enter its bottom, and granule is played to fluffing action, reduce the Particle Phase adhesion.Be subject to being fixed on the deflector effect on barrel, material is led again is back to the center of turntable district, throw to again in round as a ball, the coated process of barrel, need to add wetting agent, by the material particles surface wettability, in this process, easily on barrel, pile up with inter-adhesive and become irregular particle, or due to gravity with pile up and material particles to be pressed into oblate, in addition, granule is coated, round as a ball, compacting from level to level, its internal structure densification, moisture content is difficult to discharge, and bring very large difficulty for next step drying, and granule difference is large.

Summary of the invention

For the above-mentioned problems in the prior art, this utility model is intended to provide a kind of pill seed-coating machine that can integrate round as a ball shaping, coating, drying.

Technical solutions of the utility model are: described pill seed-coating machine comprises body, and this body is comprised of support, lower shell, upper shell and air compartment.In body, be provided with tumbler, fixed disk, powder adding device, deflector, sprayer unit, lowering or hoisting gear, drawing mechanism and conic tube.On the turning cylinder of tumbler, rotating disk is installed, lowering or hoisting gear becomes to be dynamically connected with conic tube.In conic tube, be provided with deflector, conic tube and rotating disk form a cylindrical shell.Lower shell is provided with air inlet, and air compartment is provided with extractor fan, in air compartment, is provided with filter bag.On support, also can be provided with scavenge pipe.

This utility model compared with prior art, the principles such as water conservancy diversion backflow, airpillow-dry on the basis that has used centrifugal round as a ball pelletize principle, have been recycled, in same container, complete round as a ball shaping, coating, dry overall process, therefore avoided secondary pollution, and made pill any surface finish, particle diameter is even, roundness good, qualification rate is high, but and continuous automatic production, be not only applicable to pharmaceutical industry, also can apply to the industries such as chemical industry, food, cosmetics.

Fig. 1 is this utility model structural representation;

Fig. 2 is one of this utility model duty schematic diagram.

The specific embodiment

Below in conjunction with accompanying drawing, this utility model is made to detailed description.

Described pill seed-coating machine comprises body, described body is comprised of support 1, upper shell 8, lower shell 2 and air compartment 10, in described body, is provided with tumbler 3, fixed disk 4, drawing mechanism 5, powder adding device 13, deflector 14, sprayer unit 15, lowering or hoisting gear 9, screen cloth 16, conic tube 7.Fixed disk 4 is installed on support 1, and tumbler 3 passes the center of fixed disk 4, and is arranged on fixed disk 4; Rotating disk 6 is installed on the turning cylinder in tumbler 3, and this turning cylinder can make the electrodeless adjustable high speed rotating of rotating disk 6, and space is left between the inwall of the lateral edges of described rotating disk 6 and fixed disk 4 in the position of rotating disk 6 in fixed disk 4.Conic tube 7 is fixed on fixed disk 4, and itself and rotating disk 6 form a cylindrical shell, and deflector 14 is placed in this cylindrical shell, between the bottom of deflector 14 and rotating disk 6, also leaves space.Conic tube 7 can or rotate counterclockwise by the clockwise of lowering or hoisting gear 9 and do respectively upper and lower displacement.Between the inwall of the outer wall of fixed disk 4 and lower shell 2, be provided with screen cloth 16.Ventilation duct 19 also is fixed on fixed disk 4, to it, passes to the pure air of certain pressure, can make to form air curtain in the space of fixed disk 4 and rotating disk 6, plays and avoids material particles enter this space and granule is played to fluffing action.Described lowering or hoisting gear 9 is dynamically connected with 7 one-tenth of conic tubes.Lower shell 2 is provided with air inlet 17, and air compartment 10 is provided with extractor fan 12, in air compartment 10, is provided with filter bag 11, and filter bag 11 can avoid extractor fan 12 that tiny drug particles is siphoned away.On support 1, also be provided with scavenge pipe 18, be convenient to clean in body.

When above-mentioned pill seed-coating machine work, the material master batch is dropped in rotating disk 6, by tumbler 3, drive the stepless adjustable high speed rotating of rotating disk 6, material particles is got rid of to fixed disk 4 and conic tube 7 inwalls in the mode of eddying motion by the center of rotating disk 6; Then to the ventilation duct 19 under fixed disk 4, pass to the pure air of certain pressure, between fixed disk 4 and rotating disk 6 fine clearance, form air curtain, play and stop that material particles enters wherein, loose particles, prevent the effect of particle adhesion.And be fixed on deflector 14 on upper shell 8 by these granules that get rid of center of guide revolving disk 6 again, simultaneously, powder adding device 13 and sprayer unit 15 add appropriate powder and wetting agent to material particles, and material particles is coated from level to level by powder and wetting agent, round as a ball growing up; When material particles by coated when the certain thickness, just stop adding powder and spraying, lowering or hoisting gear 9 clockwise rotates conic tube 7 is promoted to certain altitudes, makes passage 20 to occur between conic tube 7 and rotating disk 6, material particles enters screen cloth 16 by passage 20.This moment, extractor fan 12 was started working, hot-air enters in cylindrical shell by air inlet 17, material particles seethes with excitement under the effect of thermal air current, along with the air-flow that rises gradually between upper shell 8 and conic tube 7, floating, until cross conic tube 7, return on rotating disk 6, so circulation, be dried to material particles up to standard gradually.Lowering or hoisting gear 9 rotates counterclockwise conic tube 7 is descended, and extractor fan 12 quits work, and material particles comes back in rotating disk 6, coated, round as a ballly grows up, dry again, and so circulation, become qualified dried granule.After round as a ball shaping, sprayer unit 15 adds appropriate coating solution to material particles, and lowering or hoisting gear 9 makes conic tube 7 rise again afterwards, extractor fan 12 is task again, hot-air seethes with excitement material particles, crosses conic tube 7 and is back in rotating disk 6, obtains coated granule up to standard.Finally drawing mechanism 5 is opened, discharged grain products.
