Embodiment Construction

[0030] Now in conjunction with accompanying drawing, the present invention is described in further detail.

[0031] like figure 1 , figure 2 , image 3 and Figure 4 The Artemisia hot air penetrating countercurrent dryer shown in the snow includes a dryer 11 and an induced draft fan A. The two ends of the dryer 11 are respectively provided with an exhaust hood 6 and an intake hood 12, and the exhaust hood 6 is connected to the induced draft fan A. , the induced draft fan A is connected to the tube side of the shell-and-tube heat exchanger 7 and then emptied; the air inlet end of the shell-side of the shell-and-tube heat exchanger 7 is connected to the blower 8, and the air outlet end is connected to the air inlet hood 12 through the steam fin heater 10; 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 panel 38 and blades 31. The blades 31 are arranged in a hollow anti-drop shape that is ra...

Abstract

The invention discloses a hot-air through type counter flow dryer for short stalk monkshood roots. 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 is 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. Blades of an impeller of the draught fan are in a hollow inverted water drop shape, and a back plate of the impeller is of a dish-shaped structure. The contour line of the draught fan is an involute. The hot-air through type counter flow dryer achieves through type counter flow drying of the short stalk monkshood roots through the draught fan, the heat exchanger, closed conical hoppers arranged below a sieve plate steel strip and axial-flow fans arranged in the conical hoppers, the drying efficiency is improved, the drying speed is increased, and energy consumption is reduced; the blades are in the hollow inverted water drop shape, and the back plate is of the dish-shaped structure, so that dust on the impeller of the draught fan is cleaned up in real time, the strength of the impeller of the draught fan is improved, stability is enhanced, safety accidents caused by dust accumulation is effectively eradicated, and the application prospects are wide.

Description

technical field [0001] The invention relates to a drying machine for traditional Chinese medicinal materials, in particular to a hot air penetrating countercurrent drying machine in which the fan does not accumulate dust. Background technique [0002] Artemisia japonica is the dried root tuber of Aconitum brevifolia, a plant of the Ranunculaceae genus. It has the effects of dispelling rheumatism, promoting blood circulation and relieving pain. Due to its mature technology, strong adaptability, low operating cost and strong reliability, the hot air dryer is still one of the main preferred equipment for drying materials. If the material can be penetrated and countercurrently dried during the hot air drying process, And the effective recovery of tail heat is of special significance for improving drying efficiency and realizing energy saving and emission reduction. [0003] The drying of Artemisia sativa on the snow mainly adopts the hot air dryer. The induced draft fan is the ...
