Machine Characters
1The machine is mainly designed for drying fibers, the drying ability has nothing to do with the fabric weight, only related with moisture content.
2If soft and fluffy effects are required for the fiber, It is necessary to reduce the working speed. If drying purpose is required only, the working speed can be raised.
3When drying fabric, the machine is in the highest temperature, then the blower power consumption is only 20KW, the total driving power is 26KW, so how to control the temperature plays a main role for energy saving, energy saving, increase efficiency. Therefore, reasonable use of the machine and selecting the appropriate conditions of operation is of great significance.
Working principle
1, the feeding of the fabric from inlet to outlet is composed of five groups of active guideing rollers, the fabric has no tension in the transferring process. Because the continuous transmission of the driving guiding rollers, so that the fabric It is high possible to realize the high transfer effect and the continuity and automation of the whole process. The fabric of the line speed is decided by five groups of guiding rollers, DC synchronous adjusted motor transmission to controll the appropriate speed. The principle of drying fabric is forced to transfer heat, water molecules is evaporated away by hot air. So as long as the fabric goes through the WMH874B - 180 type machine, fabric moisture will be evaporated out, fabric can be with the bright color, soft hand feeling, strong fluffy feeling and the full effect of blank.
2, the fabric going into the non contact drying box is a loose, horizontally stentered and wave shape in feeding direction, slight contacted with the airflow channel that plays the supporting role. Fabric in the waveform channel is fully slipped, not closely contacted with any metal surface, fabric in a rectangular waveform channel transferring and contacting hot air in tangent direction, 3 left 2 right, and blowing the blank in perpendicular direction, therefore, in the strongly blowing in the vertical direction, the blank can be fully erected, especially fiber fabric after hot air blowing left and right, the hardening phenomenon of the fiber disappears, friction and tension force of the yarns eliminated, so blank erection have been fully assuranced, feeling can be improved, the yarn shows its soft and fluffy feeling.
3, because the fabric channel corrugated waveform, and because of the friction force of the pipe wall and the shear stress of the hot air, that makes the gas flow show the same corrugation shape, so that the hot air caused a sine wave shock strongly in the round pipeline, the high velocity flow causes fabric wavy concussion and transfers to the fabric. Due to the concussion of fabric, flexibility, quality of the fabric improved and ensured, fabric to get loose lag fully.
4, hot air circulation is a ring flow in a single direction, a closed loop system (only a small amount of added), so the heating up fast, heat concentration and heat consumption, particularly the temperature in the inlet end is high, that can greatly improve the heat efficiency.
Structure features:
1, All the positions of the machine even slightly contacted with the fabric and all fabric channel, are made of high-quality stainless steel materials, meeting the flat, light, smooth requirements.
2, fabric does not contact metal surface, just move in the air flow channel fully. Basically keep the fabric no-contacted condition.
3, the transmission mechanism and a fabric delivery system ensure the fabric radial tension force as low as possible.
4, due to the high speed transfer of the fabric, the fabric keep the wave-shape motion, in the process of fluffy-drying, produce a certain amount of flying floss layer are produced, that covering all the corners and surface of the structure, this will affect the thermal efficiency, so the plate type filtering nets are installation before the radiator, to purify the hot air flow, that will greatly improving the speed and efficiency of the air heating.
5, the cab is the closed structure, the covering plate of the cab door is made of heat insulating material, and is provided with a heat recycled device, so as to improve the heat efficiency.
6, base frame, the frame is steel structure, and fabric contacted parts are made from polished high-quality stainless steel materials, the surface of the drying room is coated with heat-resistant paint, to prevent rust.
7, the machine has unique advantages of energy saving, fast heating, high efficiency. Energy-saving consideration covers all the details of the structure, that make the machine less energy loss, high thermal efficiency. Energy saving performance is remarkable.
8, the machine has the advantages of simple structure, simple operation, convenient maintenance, no need of special technical workers to operate.
