Description

Airflow dryer
Technical field
The utility model relates to the drying plant for dyeing and printing process, particularly a kind of novel energy-conserving airflow dryer.
Background technology
Drying machine is the larger equipment of energy consumption in the finishing process in printing and dye-ing, and the cotton dyeing and finishing needs to experience 4 ~ 5 road baking operations from fabric is singed the thermal finalization process: steaming oxygen floats → dries, mercerising alkali cleaning → oven dry, wind bottoming → oven dry, reduction washing → oven dry, fixation starching (soft finish) → oven dry, so one of emphasis that energy-saving drying machine is printing and dyeing enterprise to be developed always.
Existing weaving drying machine generally adopts the steam-type drying machine.The steam-type drying machine has a plurality of drying cylinder columns, distinguishes a plurality of steam baking tubes of stationary arrangement with bearing between the drying cylinder column.Therefore steam baking tube is the middle cylinder of holding high-temperature steam, adopts that resistance to pressure is strong, the material of good thermal conduction is made, and barrel has certain thickness.Cloth transmits at steam baking tube successively, relies on the temperature of steam baking tube, to the fabric drying and processing.
The steam-type drying machine is commonly Open architecture, and the steam-type drying cylinder all is to expose outside, can observe directly the whole course of work.But, each steam baking tube of steam-type drying machine all is in the condition of high temperature, the heat that whole steam-type drying machine distributes is very many, cause whole workshop extreme temperatures, particularly summer, staff's physical demands is large, under rugged environment like this, not only bad for health, and there is potential potential safety hazard.Because distributing of amount of heat caused the serious waste of resource.
Summary of the invention
The utility model is low for existing steam-type drying machine heat utilization rate, and energy resource consumption is high, and the shortcoming large to surrounding environment influence provides a kind of heat utilization rate high, and energy resource consumption is little, and surrounding environment is not almost had influential Novel hot-air drying machine.
For achieving the above object, the utility model can be taked following technical proposals:
