Description

Chinese-medicinal material drying equipment

Technical Field

The utility model belongs to chinese-medicinal material production and processing field, in particular to chinese-medicinal material drying equipment.

Background

The traditional Chinese medicinal materials refer to medicinal materials produced in a region with specific natural conditions and ecological environment, and have certain elaboration on cultivation technology, harvesting and processing due to concentrated production, so that the traditional Chinese medicinal materials are better in quality and better in curative effect than the same medicinal materials in other regions. The Chinese medicinal materials include rhizoma Polygonati, Coptidis rhizoma, radix Angelicae sinensis, Bulbus Fritillariae Cirrhosae, rhizoma Gastrodiae, flos Lonicerae, Saviae Miltiorrhizae radix, rhizoma corydalis, stigma croci Sativi, Ginseng radix, radix Panacis Quinquefolii, Scutellariae radix, Glycyrrhrizae radix, radix Glehniae, fructus Lycii, radix Platycodi, Carthami flos, radix Paeoniae, peony, Corni fructus, rehmanniae radix, flos Trollii, Eucommiae cortex, Coicis semen, rhizoma Dioscoreae, semen Ginkgo, Galla chinensis, Polyporus, and radix astragali.

After the Chinese medicinal materials are harvested, most of the Chinese medicinal materials need to be dried, sliced or ground into powder. During drying, the traditional Chinese medicine is dried by a dryer, the dryer comprises a drying box, a plurality of layers of hollow drying plates are arranged in the drying box, and an air guide channel is arranged in a wall body at the bottom of the drying box; the air guide channel is communicated with the fan, and a heating pipe is arranged in the air guide channel. During the use, to treat the chinese-medicinal material of drying place the drying plate on, start fan and heating pipe, the heating pipe heats the wind current that the fan produced, and wind current heats back through the bottom rebound of wind-guiding passageway from the stoving case, and then dries the chinese-medicinal material on the drying plate.

Because the traditional Chinese medicinal materials with drying function have larger water content from the upper part, in the drying process, the air flow can carry a large amount of moisture to move upwards, so that the humidity of the traditional Chinese medicinal materials above is larger, and the traditional Chinese medicinal materials are not beneficial to subsequent preservation. In addition, because the air flow firstly contacts with the bottoms of the traditional Chinese medicinal materials when passing through the drying plate, the heating quantity of the tops of the traditional Chinese medicinal materials is relatively less, and the drying effect of the traditional Chinese medicinal materials in the drying box is further uneven.

SUMMERY OF THE UTILITY MODEL

The utility model discloses it is anticipated to provide a chinese-medicinal material drying equipment to improve the homogeneity that chinese-medicinal material was dried.

The drying equipment for the traditional Chinese medicinal materials comprises a drying box, a fan, a ventilation pipe, a heater and a conveying mechanism; an air guide channel is arranged in a wall body at the bottom of the drying box and is communicated with the fan through a ventilation pipe, and the heater is connected with the ventilation pipe; the conveying mechanism comprises a plurality of guide arcs and a plurality of conveying belts which are in transmission connection with the drying box, vent holes are uniformly distributed on the conveying belts, the plurality of conveying belts are sequentially arranged in the drying box from top to bottom, a blanking port for Chinese medicinal materials to pass through is arranged between one end of each conveying belt and the inner wall of the drying box, and the blanking ports formed between the adjacent conveying belts and the drying box are positioned on different sides; the guide arcs are arc-shaped, the guide arcs are respectively positioned at the blanking ports, the concave side faces of the guide arcs towards the discharge end of the upper-layer conveying belt, the bottoms of the guide arcs are contacted with the feed end of the lower-layer conveying belt, each guide arc comprises a rotating shaft group and a guide belt sleeved on the rotating shaft group, each rotating shaft group comprises a plurality of rotating shafts which are rotatably connected to the drying box, and the rotating shafts form an arc shape from top to bottom; the conveying belt is in transmission connection with the material guiding belt; the top of stoving case is equipped with the feed port, and the bottom of stoving case is equipped with the discharge opening, and the discharge opening is located the discharge end of bottommost conveyer belt.

The working principle and the beneficial effects of the scheme are as follows: when the drying device is used, the dried traditional Chinese medicinal materials are placed on the topmost conveying belt through the feeding holes, and the conveying belt and the material guide belt are conveyed; starting the fan and the heater, heating the air generated by the fan by the heater to form hot air, and drying the Chinese medicinal materials in the drying box by the hot air entering the air guide channel. Because the Chinese medicinal materials move downwards from the top and the hot air moves upwards from the bottom, the contact temperature and the contact humidity of the Chinese medicinal materials are higher and lower, and the drying quality of the Chinese medicinal materials is further ensured; the problem of among the prior art multilayer stoving lead to the top chinese-medicinal material to dry inadequately is avoided. In addition, at the in-process of conveyer belt transmission chinese-medicinal material, the in-process that chinese-medicinal material enters into the below conveyer belt from the conveyer belt of top through the blanking mouth, after it contacts the guide area, under the effect of rotating shaft group for the upper surface and the guide area laminating of chinese-medicinal material, then on entering into the conveyer belt of below, and then realized new 180 with chinese-medicinal material upset, further improved the homogeneity that chinese-medicinal material was dried. The chinese-medicinal material drying equipment in this application is particularly suitable for section chinese-medicinal material.

Further, the feeding ends of the conveyor belts are higher than the discharging ends. The feed end of conveyer belt is higher than the discharge end for chinese-medicinal material enters into guide belt wheel section from the conveyer belt of top, makes the upper surface of chinese-medicinal material to the guide belt, more is favorable to the upset of chinese-medicinal material.

Further, the bottom of the drying box is provided with a collecting box, and the collecting box is positioned under the discharge hole and communicated with the discharge hole. Through setting up the collecting box for the chinese-medicinal material that conveys on the conveyer belt can directly fall into and collect in the collecting box.

Further, fixedly connected with preheating cabinet on the outer wall of stoving case, also be equipped with the conveyer belt in the preheating cabinet, be equipped with the venthole on the wall body of stoving case, the venthole is located the feed end of the conveyer belt of stoving incasement top, the venthole with the bottom intercommunication of preheating cabinet. Through the setting of preheating cabinet, the chinese-medicinal material of treating the stoving still can be treated to the hot-blast stoving that flows out from the stoving incasement is dried in advance, and then improves hot-blast availability factor.

Furthermore, a discharge port is arranged on the preheating box and is positioned between the feed port and the discharge end of the conveyor belt in the preheating box. Through the setting of discharge gate for the chinese-medicinal material through preheating in the preheating cabinet can directly enter into the stoving incasement and dry, improves drying efficiency.

Furthermore, the side wall of the feeding hole is rotatably connected with a separation plate, and the bottom of the separation plate is provided with a spring for supporting the separation plate. Through the setting of spring and division board for the chinese-medicinal material that the top dropped can push down the division board and enter into stoving incasement and dry, when the top does not have chinese-medicinal material to enter into, makes the division board seal the feed port, and then makes steam flow from the venthole, and the steam that the venthole flows can further be dried the chinese-medicinal material in the preheating cabinet, thereby reduces thermal waste.
