Detailed Description
The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.
As shown in fig. 1 to 5, the pharmaceutical material drying and drying system comprises a long drying cavity 1, a mesh conveyor belt 8 is arranged in the long drying cavity 1 in a penetrating manner, in order to form circulation, the mesh conveyor belt 8 in the long drying cavity 1 comprises an upper belt and a lower belt, a perforated disc 9 filled with medicine particles is placed on the upper belt, a plurality of dispersing units 10 are arranged between the upper belt and the lower belt, and the bottoms of the dispersing units 10 are connected with an air system.
A plurality of extraction fans corresponding to the dispersion units 10 are arranged at the top of the long drying cavity 1. During operation, the wind system produces hot-blastly, then carries out the drying to the medicine grain, can let the moisture in the medicine grain form steam after the drying and disperse, then this steam is taken out through taking out the fan along with hot-blastly to form stoving drying. Because the hot air mode is adopted, the medicine particles can be wound around the medicine particles, and therefore, the medicine particles can be dried well.
As shown in fig. 1, in the long drying chamber 1, in the direction of the mesh conveyor belt 8: sequentially dividing the temperature zone into a high temperature zone, a medium temperature zone and a normal temperature zone; wherein, in the high-temperature area, the dispersion unit 10 is communicated with a high-temperature hot air pipeline of the air system; in the medium-temperature area, the dispersion unit 10 is communicated with a medium-temperature hot air pipeline of an air system; in the normal temperature region, the dispersing unit 10 is communicated with a normal temperature air pipeline of the air system. When the temperature is from high to normal temperature during drying and drying, the discharged medicine particles can not absorb moisture in the air when reaching the normal temperature, and the dryness of the medicine particles can be better maintained.
And the air system forms air by arranging the high-temperature heating chamber, the medium-temperature heating chamber and the common heating chamber, so that large air volume can be ensured. When the dispersion unit works, the three parts extract air from the atmosphere, correspondingly heat the air and then respectively feed the air into the drying chamber for drying, and the drying chamber is communicated with the bottom of the dispersion unit 10 through the corresponding air pipeline by the blower fan.
The dispersing unit 10 is used for uniformly dispersing the hot air entering from the air system and avoiding concentration, so that each part in the long drying cavity 1 can be heated, and drying is realized.
Specifically, as shown in fig. 3 and 4, the dispersion unit: the drying device comprises a plurality of vertical dispersion pipes 4, wherein the dispersion pipes 4 are tightly attached to each other and are hooped by an outer cylinder 3, and the outer cylinder 3 is fixed in a long drying cavity 1 through a bracket; the dispersing pipes 4 are provided with channels after hooping, and channels are formed among the dispersing pipes 4; the arrangement of the dispersion pipe 4 prevents excessive hot air from being concentrated at a central position. The hot air is communicated with the bottom of the outer cylinder 3 through a pipeline, the air quantity in the center of the channel is large, but the channel passing through the dispersion pipe 4 at the middle position is limited, so that the hot air has to pass through the channels of other dispersion pipes 4, and the hot air is uniformly dispersed.
When the hot air flows upward, the bottom surface and the peripheral side surface of the pellet are dried, and the top surface is not necessarily dried well. To avoid this, the dispersion tube 4 is then caused to generate pulsed hot air, causing the pellets to tumble in a shaking motion.
As shown in fig. 4 and 5, a rotating shaft 5 is provided in the dispersion pipe 4 in a radial direction thereof, a weight 6 and a blade 7 are provided on the rotating shaft 5, and the blade 7 and the dispersion pipe 4 are provided at 90 °. When hot air passes through, when the included angle between the surface of the blade 7 and the axial direction of the dispersion pipe 4 is 45-90 degrees, the blade is mainly acted by the hot air to form positive rotation; when the surface of the blade 7 and the axial included angle of the dispersion pipe 4 is 0-45 degrees, the blade is mainly reversed under the action of the weight 6. When the blade 7 is just reversing, can let the hot-blast time that dispersion pipe 4 discharged big time spent, form the hot-blast of similar pulse, this hot-blast can lead to the medicine grain to beat and roll to let each side can both obtain good stoving.
The outer cylinder 3 may be too large in size, and one air inlet duct may not meet the air inlet requirement, so that a plurality of partition plates are arranged at the bottom of the outer cylinder 3, the outer cylinder 3 is divided into a plurality of air inlet chambers by the partition plates, and each air inlet chamber is connected with one air inlet duct for hot air.
