Description
Technical field
The present invention relates to a kind of dryer, refer specifically to air-introduced machine will not the heat-pump-type tail recuperation of heat of laying dust penetrate adverse current and dry
Machine.
Background technology
Drying of the drying temperature less than 60 degrees Celsius is typically turned into low temperature drying by people, and low temperature drying is widely used in making
The drying of the heat sensitive materials such as species, Chinese medicine, biological products.Hot air type drier due to technology maturation, it is adaptable,
Operating cost is low, highly reliable, is still one of preferred unit of low temperature drying.Low temperature drying due to exhaust emissions temperature compared with
It is low, thus it is more difficult enter end of line recuperation of heat.If can be realized during hot air type low temperature drying to material penetrate and it is inverse
Stream drying, and tail heat is effectively reclaimed, then it is especially important for improving drying efficiency and realizing that energy-saving and emission-reduction all have
Meaning.
Air-introduced machine is the key equipment of heated air drier, and air-introduced machine is generally centrifugal blower, air-introduced machine it is continuous, steady
Calmly, reliably working is very crucial to dryer, because the occasion that dryer uses all contains certain dust, air-introduced machine work mostly
When making, air-flow during the draught fan impeller of high speed rotation by that can be departed from air-flow phase and be deposited due to centrifugation, dust granule
It is attached on draught fan impeller.
Because draught fan impeller rotating speed is general all higher, as long as with the presence of micro dust in air-flow, after working long hours all
More dust can be accumulated, so as to change the balance of draught fan impeller rotation, if draught fan impeller does not have self purification to dust
Also do not clear up in time, will static state cumulative and that draught fan impeller is altered in steps and dynamic equilibrium, so as to produce vibration.
Come off once the dust that running into has part hardened is vibrated, the dynamic rotary away from air-introduced machine will balance, then produce immediately
Judder, this may trigger serious personnel and equipment safety accident.
Therefore, if a kind of centrifugal type draught fan impeller can be designed, automatic cleaning can be carried out and just caused without worry
Dust accumulates, and all has especially important meaning for keeping the reliable and stable work of air-introduced machine and preventing security incident.
The content of the invention
The technical problem to be solved in the present invention is exactly overcome the deficiencies in the prior art, there is provided a kind of simple and practical, energy
The heat-pump-type tail recuperation of heat of dust penetrates adverse current dryer on automatic cleaning draught fan impeller.
For overcome the deficiencies in the prior art, the present invention takes following technical scheme：
A kind of heat-pump-type tail recuperation of heat penetrates adverse current dryer, including drying body chassis and air-introduced machine, it is characterised in that；Dry
