Embodiment Construction

[0029] The present invention will now be further described in detail with reference to the accompanying drawings.

[0030] like figure 1 , figure 2 , image 3 and Figure 4 The shown Panax notoginseng hot-air penetrating countercurrent dryer includes a dryer 11 and an induced draft fan A. The two ends of the dryer 11 are respectively provided with a draft hood 6 and an air inlet hood 12. The fan A is connected to the tube side of the tubular heat exchanger 7 and then emptied; the inlet end of the shell side of the tubular heat exchanger 7 is connected to the blower 8, and the outlet end is connected to the air inlet hood 12 through the steam fin heater 10; the The induced draft fan includes a fan impeller 41 and a casing 45. The fan impeller 41 includes an impeller back plate 37, an impeller face plate 38 and blades 31. The blades 31 are arranged in a hollow anti-drop shape with radial and central symmetry of the impeller shaft; the hollow anti-drop-shaped blades 31 The i...

Abstract

The invention discloses a hot-air through counter flow dryer for panax notoginseng. The two ends of the dryer are provided with a draught hood and an air intake hood respectively. The draught hood is connected with a draught fan. The draught fan is connected with a tube pass of a tubular heat exchanger and then emptied. The air inlet end of a shell pass of the tubular heat exchanger is connected with an air blower. The air outlet end of the shell pass of the tubular heat exchanger is connected with the air intake hood through a steam finned heater. An impeller of the draught fan is provided with blades which are of a hollow inverted-water-drop-shaped structure. The hot-air through counter flow dryer is provided with the draught fan, the heat exchanger and closed conical hoppers arranged below a sieve plate steel strip, and axial-flow fans are arranged in the conical hoppers, so that through type counter flow drying of the panax notoginseng is achieved, the drying efficiency is improved, the drying speed is increased, and energy consumption is also reduced; since the blades are of the hollow inverted-water-drop-shaped structure, dust on the impeller of the draught fan is cleaned away in real time, the strength of the impeller of the draught fan is improved, stability is enhanced, safety accidents caused by dust accumulation are effectively eradicated, and the application prospects are wide.

Description

technical field [0001] The invention relates to a drying machine for Chinese medicinal materials, in particular to a Panax notoginseng hot air penetrating countercurrent drying machine in which dust is not accumulated by a guiding fan. Background technique [0002] Panax notoginseng, also known as Tianqi, is a Umbelliferae Araliaceae plant, mainly distributed in Yunnan, Guangxi, Jiangxi, Sichuan and other places. The root of Chinese herbal medicine Panax notoginseng is used as a medicinal part. It has the functions of dispersing blood stasis and stopping bleeding, reducing swelling and relieving pain. It is a kind of Chinese herbal medicine with high frequency of use, and Panax notoginseng generally needs to be dried before being used as medicine. Due to its mature technology, strong adaptability, low operating cost and strong reliability, hot air dryer is still one of the main preferred equipment for material drying. Effective recovery of tail heat is of great significanc...
