Description
Technical field
The present invention relates to a kind of dryer, the concrete blower fan that guides can not the heat-pump-type tail recuperation of heat adverse current dryer of laying dust.
Background technology
Baking temperature is generally become low temperature drying lower than the drying of 60 degrees Celsius by people, and low temperature drying is widely used in the drying of the heat sensitive materials such as crop seed, Chinese medicine, biological products.Hot air type drier due to technology maturation, adaptable, operating cost is low, reliability is strong, one of preferred unit remaining low temperature drying.Low temperature drying due to exhaust emissions temperature lower, thus more difficultly carry out tail recuperation of heat.If penetrating and adverse current oven dry material can be realized in hot air type low temperature 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.
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, the heat-pump-type tail recuperation of heat adverse current dryer of dust on energy Automatic clearance draught fan impeller.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
