Description
Technical field
The present invention relates to medicine drying equipment, be specially a kind of stagewise drying device.
Background technology
In pharmaceutical industry, a lot of medicines is all need could form qualified product through granulation, drying, screening.Medicine particle is made rear unification and to be put together drying.But the grain diameter often made when granulation differs, the drying time of needs is not identical yet, and the particle of different-grain diameter is put together drying, easily make the denser of particle packing, be unfavorable for the evaporation with moisture that enters of hot-air, thus cause drying efficiency lower.
Summary of the invention
The object of this invention is to provide a kind of stagewise drying device, particle is not distinguished to solve in prior art, the problem that unified drying efficiency is lower.
To achieve these goals, a kind of stagewise drying device provided by the invention, comprises casing; The top of described casing is provided with charging aperture, bottom is provided with discharging opening, is provided with multiple horizontal conveying belt parallel to each other, from top to bottom in casing, the left side wall of the contiguous casing of odd bits conveyer belt is arranged, and rotate toward dextrad, the right side wall of the contiguous casing of even bit conveyer belt is arranged, and toward left pivot movement, described conveyer belt is provided with sieve aperture, the screen number of conveyer belt increases gradually from top to bottom, and bottom half is provided with the air-heater be communicated with box house, and the top of casing is provided with blast pipe.
By arranging multiple parallel to each other and counter-rotational horizontal conveying belt in casing, adjacent conveyor belts is crisscross arranged, and the feed end of the discharge end of upper strata conveyer belt corresponding lower floor conveyer belt, material is made to fall into conveyer belt from its top feed mouth of casing, horizontal movement on a moving belt, then fall into the feed end of lower one deck conveyer belt from discharge end, thus add the time of staying of material in casing, be convenient to abundant drying.Sieve aperture is set on a moving belt, and the screen number of conveyer belt increases gradually from top to bottom, for being sieved by the material of different-grain diameter.
Operation principle: start conveyer belt and rotate and lead to hot blast by air-heater in casing, then the temperature inside the box is raised puts into the conveyer belt of the casing the superiors by material from charging aperture, the material that material particular diameter is less than the screen-aperture on conveyer belt can drop downwards through conveyer belt, and impenetrable just stop is moved on a moving belt together with conveyer belt.The meeting that material particular diameter is larger rests on top conveyer belt, time needed for from the conveyer belt in top portion to discharging opening is longer, the meeting that material particular diameter is less drops on conveyer belt on the lower, time needed for from conveyer belt on the lower to discharging opening is shorter, thus the drying time of the time of the drying of the material the making grain diameter large material little relative to grain diameter is long, realizes classification drying.
Compared with prior art, the advantage of this programme is: by arranging multiple netted conveyer belt in casing, and the order number of the sieve aperture of conveyer belt increases gradually from top to bottom, the time that the material of different-grain diameter is stopped on a moving belt is different, thus the dry materials time realizing Large stone is long, the drying time of small particle diameter is short, thus realizes classification drying, improves drying efficiency.
Further, described casing is provided with the guide duct with fan, and guide duct is positioned at the outside of conveyer belt discharge end, and the air inlet of guide duct is just to the space on the downside of conveyer belt, and the air outlet of guide duct is just to the space on the upside of conveyer belt.By the guide functions of guide duct, air is produced and flows fast, thus make the more uniform temperature in casing, simultaneously, the wind direction of the air outlet blowout of guide duct is contrary with the rotation direction of conveyer belt, thus makes air fast from material table surface current mistake, accelerates the evaporation rate of moisture on material.
Further, described guide duct is provided with moisture separator I.Moisture separator is separated through the moisture in the humid air of guide duct, obtains dry air, is conducive to reducing the air humidity in casing.
Further, described conveyer belt is provided with eccentrically weighted shaft.Eccentrically weighted shaft can produce effect of vibration to conveyer belt when rotating, and is conducive to conveyer belt and sieves material.
Further, described blast pipe is provided with moisture separator II.Be conducive to the aqueous vapor in casing to be discharged, reduce the humidity in casing.
Further, described blast pipe communicates with the air inlet of air-heater.When air is discharged by blast pipe, with certain heat in air, by being communicated with air-heater by blast pipe, be conducive to heat recovery, economize energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of a kind of stagewise drying device of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
In figure: casing 1, conveyer belt 2, blast pipe 3, eccentrically weighted shaft 4, air-heater 5, guide duct 6, charging aperture 11, discharging opening 12.
A kind of stagewise drying device as shown in Figure 1, comprises casing 1, and the top of casing 1 is provided with blast pipe 3, and blast pipe 3 is provided with moisture separator II, and be provided with the air-heater 5 be communicated with casing 1 inside bottom casing 1, blast pipe 3 is communicated with air-heater 5.The top of casing 1 is provided with charging aperture 11, and bottom is provided with discharging opening 12.Five parallel to each other and netted conveyer belts 2 of the level of reverse drive are provided with in casing 1, number from top to bottom, is positioned at the conveyer belt 2 of odd bits, and its left end is feed end and close casing 1, the right-hand member of conveyer belt 2 as discharge end, and and be provided with the gap of blanking between casing 1; Be positioned at the conveyer belt 2 of even bit, its right-hand member is feed end and near casing 1, and its left end is as discharge end and and be provided with the gap of blanking between casing 1.The screen number of conveyer belt 2 increases gradually from top to bottom.Conveyer belt 2 is provided with eccentrically weighted shaft 4.The position corresponding with the discharge end of conveyer belt 2, the both sides of casing 1 is provided with the guide duct 6 with fan, the air inlet of guide duct 6 is just to the space on the downside of conveyer belt 2, the air outlet of guide duct 6 is just to the space on the upside of conveyer belt 2, and guide duct 6 is provided with moisture separator I.
During use, start conveyer belt 2 rotate and in casing 1, lead to hot blast by air-heater 5, by air heat in case, then material is put into the conveyer belt 2 of casing 1 the superiors from charging aperture 11, the material that material particular diameter is less than the screen-aperture on conveyer belt 2 can drop downwards through conveyer belt 2, and impenetrable just stop is moved on conveyor belt 2 together with conveyer belt 2.The meeting that material particular diameter is larger rests on top conveyer belt 2, the time moved to needed for discharging opening 12 from the conveyer belt 2 in top portion is longer, the meeting that material particular diameter is less drops on conveyer belt 2 on the lower, the time moved to needed for discharging opening 12 from conveyer belt 2 is on the lower shorter, thus the drying time of the time of the drying of the material the making grain diameter large material little relative to grain diameter is long, realizes classification drying.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
