A kind of dryer that utilizes the industrial steam exhaust steam to dry
Technical field
The utility model relates to the drying plant technical field, specifically for the drying plant of blended yarn after the printing and dyeing.
Background technology
Blended yarn needs to dry operation after dyeing, present dryer adopts the mode of electric heater blowing hot-air to dry more, and this kind drying mode temperature is adjustable, uses more convenient, but the electric energy that consumes is more, need to pay a large amount of electricity charge when raising the cost.The applicant is for this problem, it is transformed, use industrial exhaust steam to dry operation, but the temperature of exhaust steam can not satisfy the needs of rapid oven dry sometimes, need to reach the integral body transformation of dryer and use the mode of exhaust steam heat supply to dry operation.
The utility model content
For the deficiency of existing dryer, the utility model provides a kind of dryer that utilizes the industrial steam exhaust steam to dry, and simultaneously dryer is transformed, and reaches the adjustable purpose of drying rate.
The technical scheme in the invention for solving the technical problem is: a kind of dryer that utilizes the industrial steam exhaust steam to dry, comprise frame, drying chamber and conveyer belt, the circular flow in drying chamber of described conveyer belt, above described drying chamber, be provided with some hot blast unit that brush hot blast to conveyer belt, it is characterized in that, described hot blast unit comprises blower fan and steam radiating tube, and draws an auxiliary air exhauster by pipeline below described drying chamber.
Use the adjustable variable frequency control motor of rotating speed in the described auxiliary air exhauster.
Steam radiating tube in described a plurality of hot blasts unit connects in the mode of serial connection.
The beneficial effects of the utility model are: what use in the utility model is the steam exhaust steam, the temperature of exhaust steam is lower, by below described drying chamber, drawing an auxiliary air exhauster by pipeline, can improve the air velocity of the hot blast of the conveyer belt of flowing through, reach the purpose of oven dry, because the temperature of oven dry is lower, the quality of yarn also is improved in the drying course, and simultaneously, what this kind drying mode used is exhaust steam, reduce production cost, met the policy of energy-saving and emission-reduction.
Description of drawings
Fig. 1 is schematic diagram of the present utility model;
Among the figure: 1 frame, 2 drying chambers, 3 conveyer belts, 4 hot blast unit, 41 blower fans, 42 steam radiating tubes, 5 auxiliary air exhausters.
The specific embodiment
As shown in Figure 1, a kind of dryer that utilizes the industrial steam exhaust steam to dry comprises frame 1, drying chamber 2 and conveyer belt 3, the circular flow in drying chamber of described conveyer belt 3, and then drive yarn from front to back motion in drying chamber, in the process of motion, dried.Above drying chamber, be provided with some hot blast unit 4 that brush hot blast to conveyer belt, this hot blast unit comprises blower fan 41 and steam radiating tube 42, steam radiating tube in a plurality of hot blasts unit connects in the mode of serial connection, and steam moves from back to front, reaches the step by step purpose of oven dry.Characteristic for the coordinating with steam rapid heat cycle oven dry, below drying chamber, draw an auxiliary air exhauster 5 by pipeline, use the adjustable variable frequency control motor of rotating speed in the auxiliary air exhauster, can carry out variable frequency control, and then control reaches the purpose of regulating drying effect by the flow velocity of the air-flow of conveyer belt.Final so that the steam exhaust steam has realized perfect utilization in dryer, transform successful.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
