Along with the fast development of pharmaceutical technology, in order more fully, effectively to bring into play the medicine pharmacological action, slow controlled-release technology has obtained promoting rapidly and using at home.For the Cotton seeds of slow controlled release, granule, micropill, drop pill, traditional technology adopts coating pan mostly, and adopts the efficient of coating pan lower, and dust from flying is bigger in the work process.For further adapting to the demand for development of sustained-release preparation in the domestic pharmaceutical industry, more domestic medicine machines are made producer, introduce external like product respectively, centrifugal coating machine that occurs in succession such as the later stage and efficient atresia coating machine, this class coating machine mainly comprises air filtering system, heating system, pedestal, end sprayer container, diffuser casing, dust trapping chamber, induced draught system, transfusion and atomization system and control system, air after the system handles after filtration, again after the heating system heating, enter sprayer container bottom, the end, the material that drives in the container is upwards done the fluidisation motion, thereby reaches the purpose of coating.As China Patent No. is that 00219230.6 utility model patent description discloses a kind of granulating coated machine, be provided with dust trapping chamber, hothouse, fluid bed in its cylindrical shell, cylindrical shell is provided with induced duct and blast pipe, central authorities and opening that nozzle is arranged on the fluidisation porous plate make progress, the nozzle top is provided with guide, have the gap between guide and the fluidisation porous plate, the aperture that be distributed in nozzle periphery on the fluidisation porous plate, is equal to or less than the hole in the guide radius is big slightly.Above-mentioned utility model patent is owing to be bottom spraying type coating machine, and the coating droplet direction of spray gun ejection is identical with the goods fluid direction, thus contact between droplet and the material even, seriality is good, but owing to being the restriction of single guide, output is not high.In sum; though the efficient of existing coating machine is improved; large-scale production also is improved to a certain extent; but it is inhomogeneous that fluidisation in use appears in the big production type of this kind equipment; the fluidisation dead angle appears in the subregion, thereby causes coating quality not good enough, and the adapted breed scope is narrower; in the coating process, the waste of coating material is bigger.
The utility model content
At above-mentioned the deficiencies in the prior art part, it is a kind of in use can fluidisation even that this utility model provides, and reduces the end spray coating machine of coating material waste, can effectively solve the problem that above-mentioned prior art exists.
To achieve these goals, the technical solution adopted in the utility model is: spray the coating machine at the bottom of disclosing a kind of fluid bed, it comprises air filtering system, heating system, pedestal, end sprayer container, diffuser casing, dust trapping chamber, induced draught system, transfusion and atomization system and control system, has end atomization device in described transfusion and the atomization system, be provided with fluidisation area in the end sprayer container, described fluidisation area is mainly by the shunting slope that material evenly can be shunted, guide shell, air distribution plate, end atomization device is formed, described guide shell places in the end sprayer container, the shunting slope is located on the end sprayer container inwall, the quantity on described shunting slope is corresponding with guide shell, described air distribution plate is located at the inner bottom part of end sprayer container and corresponding with guide shell, and atomization device of the described end passes the bottom of air distribution plate and guide shell.
As preferably, described shunting slope is two arcwall faces that arch upward, and this shunting slope forms the taper of cambered surface rhizoma sparganic with end sprayer container inwall.
As one of further preferred version, described shunting slope is three.
As two of further preferred version, described shunting slope is more than three.
Further, the sloping centrage uniform distribution of described shunting along end sprayer container.
As preferably, be provided with the lowering or hoisting gear that to control the guide shell lifting in the outside of end sprayer container.
Compared with prior art, the beneficial effect that this utility model is brought is: the air after the system handles after filtration, after heating, enter sprayer container bottom, the end, drive the interior material of container and make it in the fluidisation tube, upwards to do the fluidisation motion, in fluid mapper process, thereby the nebulizer that is installed in the guide shell bottom evenly upwards is sprayed at the ball that is in fluidized state, the purpose that the grain surface reaches coating with the coating thing, the setting of described fluidisation area can be avoided the dead angle that fluidisation occurs in the end sprayer container, makes fluidisation more even.This utility model possesses the function of micropill, piller and granule being carried out quick coating, and has higher coating quality, and gained surface coatings thing is even, bright and clean, can prepare sustained-release preparation and taste masking is painted.
