Description
Technical field
The present invention relates to a kind of Chinese medicine dryer, the concrete blower fan that guides the pseudo-ginseng hot air type of laying dust can not penetrate adverse current dryer.
Background technology
Pseudo-ginseng has another name called pseudo-ginseng, is Umbellales Araliaceae, is mainly distributed in the ground such as Yunnan, Guangxi, Jiangxi, Sichuan.Chinese medicine pseudo-ginseng is using its root as medicinal effects, has the hemostasis of the loose stasis of blood, effect of detumescence ding-tong, cure mainly spitting of blood, spit blood, bleeding from five sense organs or subcutaneous tissue, has blood in stool, uterine bleeding, traumatism and bleeding, chest ventral spine pain, falls the symptoms such as servant swells and ache, be the Chinese herbal medicine that a kind of frequency of utilization is higher, pseudo-ginseng generally all needed to carry out drying before being used as medicine.Heated air drier due to technology maturation, adaptable, operating cost is low, reliability is strong, appointing is so one of main preferred unit of dry materials, if penetrating and adverse current oven dry material can be realized in hot-air drying process, and tail heat is effectively reclaimed, then for improving drying efficiency and realizing the meaning that energy-saving and emission-reduction all have particular importance.
The oven dry of pseudo-ginseng also mainly adopts hot air type drier; air-introduced machine is the key equipment of heated air drier; air-introduced machine is generally centrifugal blower; air-introduced machine continuous, stable, reliably working is very crucial to dryer; the occasion used due to dryer all contains certain dust mostly; during air-introduced machine work, air-flow by during the draught fan impeller of High Rotation Speed due to centrifugation, dust granule can depart from air-flow phase and deposit and be attached on draught fan impeller.
Because draught fan impeller rotating speed is general all higher, as long as there is micro-dust to exist in air-flow, all more dust can be accumulated after working long hours, thus change the balance of draught fan impeller rotation, if draught fan impeller does not have self purification not clear up in time to dust yet, will cumulative and progressively change draught fan impeller Static and dynamic balance, thus produce vibration.Have the dust that part hardens to be come off by vibration once run into, will balance away from the dynamic rotary of air-introduced machine immediately, then produce judder, this may cause serious personnel and device security accident.
Therefore, if can a kind of centrifugal type draught fan impeller be designed, Automatic clearance can be carried out and just do not worry causing dust accumulation, for keeping the reliable and stable work of air-introduced machine and stopping the meaning that security incident all has particular importance.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, provides a kind of simple and practical, and on energy Automatic clearance draught fan impeller, the pseudo-ginseng hot air type of dust penetrates adverse current dryer.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
A kind of pseudo-ginseng hot air type penetrates adverse current dryer, comprises dryer and air-introduced machine, it is characterized in that; Dryer two ends are respectively equipped with draught hood and enter fan housing, and draught hood connects air-introduced machine, emptying after the tube side of air-introduced machine connecting column pipe heat exchanger; Tubular heat exchanger shell side inlet end connects air blast, and outlet side connects into fan housing through steam fin heats device; Described air-introduced machine comprises draught fan impeller and casing, and draught fan impeller comprises impeller backboard, impeller panel and blade, and blade arrangement becomes impeller Axial and radial, the anti-water-drop-shaped of centrosymmetric hollow; The anti-water-drop-shaped blade of hollow connects impeller panel and is welded to form impeller bodies with impeller backboard; Impeller panel is provided with air inlet, impeller backboard by the fixing also connection shaft seat of rivet, and axle bed is connected by axis hole and fan shaft; Casing is provided with air inlet and air outlet, cabinet form outline line is involute, the round heart of involute and blower fan axis coinciding, involute is from inside shell air outlet, line radius strengthens gradually with involute circle, terminate outside shell air outlet, shell air outlet width equals involute circumference; Shell air inlet is provided with cover plate, cover plate also has air inlet be convenient to connecting pipe, and axle center and impeller axis coinciding.
