Cold-hot air drying chamber
Technical field
The present invention relates to a kind of drying equipment, the drying shed that particularly a kind of cold wind and hot blast can be regulated arbitrarily.
Background technology
One has the air-dry and cold wind oven dry of hot blast drying mode, with the corresponding drying room of drying mode or be the hot blast drying room, it is the cold wind drying room, adopt different drying modes need set up different drying rooms, building two kinds of drying rooms one is that floor space is big, the 2nd, the investment amount is big, also two big functions can't be flocked together simultaneously, uses very inconvenient.
Summary of the invention
The technical problem to be solved in the present invention provides and a kind ofly will integrate cold air drying and heated-air drying, can carry out hot cold wind according to instructions for use and switch dry cold-hot air drying chamber.
The object of the present invention is achieved like this: a kind of cold-hot air drying chamber, comprise drying room, and air duct communicates with drying room through blower fan with jet chimney, and fin also is housed on the air duct, is provided with the first air channel gate valve between air duct and the blower fan; Air duct communicates with dehumidifier, is provided with the 3rd air channel gate valve between air duct and the dehumidifier; Cooling tower is connected with compressor, and compressor is connected with condenser on being installed in air duct, also is provided with the 4th air channel gate valve and the second air channel gate valve on air duct.
Cold-hot air drying chamber provided by the invention, on the basis of cold air drying system, increase the hot blast feeding system, adjusting by each gate valve, can reach the purpose of cold wind, hot blast regulated at will according to different drying process requirements, realize cold and hot and usefulness in the same drying shed, not only reduce the floor space of drying equipment, also reduced the dry energy that is consumed.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples: Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of cold-hot air drying chamber of the present invention comprises drying room 4, and air duct 3 communicates with drying room 4 through blower fan 5 with jet chimney 16, and fin 15 also is housed on the air duct 3, is provided with the first air channel gate valve 10 between air duct 3 and the blower fan 5; Air duct 3 communicates with dehumidifier 9, is provided with the 3rd air channel gate valve 12 between air duct 3 and the dehumidifier 9; Cooling tower 8 is connected with compressor 7, and compressor 7 is connected with condenser 6 on being installed in air duct 3, also is provided with the 4th air channel gate valve 13 and the second air channel gate valve 11 on air duct 3.
Operation principle of the present invention is as follows: when needing heated-air drying, open air intake switch 2, the first air channel gate valve 10 on the air duct 3, close the 3rd air channel gate valve 12, the second air channel gate valve 11, the 4th air channel gate valve 13, condenser 6, compressor 7, cooling tower 8, dehumidifier 9, start blower fan 5, air inlet 1 air intake, open steam cock 16, enter pipeline by steam from jet chimney 14, heat and circulate through 15 pairs of drying room air of fin and carry out drying; Then just opposite in the time of needs cold wind, close air intake switch 2, the first air channel gate valve 10, open the 3rd air channel gate valve 12, the second air channel gate valve 11, the 4th air channel gate valve 13, condenser 6, compressor 7, cooling tower 8, dehumidifier 9, start blower fan 5, make temperature decline and circulation in air duct 3 in the pipeline by compressor 7, cooling tower 8 and condenser 6, adsorb by moisture in the air in 9 pairs of pipelines of dehumidifier 3, reach drying effect.The 4th air channel gate valve 13 is a stop valve, and the second air channel gate valve 11 is used for regulating air quantity.
