The drying drum is a pressure vessel, and the pressure gauge, safety valve and air safety valve must be installed in accordance with the provisions of the "Pressure Vessel Safety Supervision Regulations". The pressure surface reading should not be greater than one times the working pressure. And marked with a red line for work stress. The discharge capacity of the relief valve must be greater than the safe discharge capacity of the container, and the vents should be oriented in the direction of no-one. Safety accessories must be sensitive, effective and checked regularly. Drying drum should be regularly thickness or hydraulic check. According to the strength calculation regulations of relevant departments, if the wall of the cylinder is worn and thinned to 1.5mm thickness, there will be an explosion risk and it should be scrapped and renewed.

To clean the surface of the stainless steel drying drum, spray a layer of polytetrafluoroethylene anti-bonding film on the drying drum, which is convenient to clean, safe and prolong the service life. Other drying cylinder dirt is not much, can be used brush and soap cleaning. To ensure the safe use of pressure vessels.

All kinds of gas heating and drying machine should be equipped with ignition interlock safety device and flame monitoring alarm, into the gas machine sealed drying room, should be monitored outside. Open flames are strictly prohibited. The gas ignition operator should have professional training, and pass the examination, and can operate independently with the certificate.

In order to prevent the drying drum suction equipment accident, it is necessary to understand the principle of preventing the formation of vacuum in the drying drum. When the dryer starts, it should first open the empty car, open the air safety valve of the drying drum, and discharge all the condensed water (about 5min later), and then slowly open the steam and close the air valve. Preheat the drying drum for 5-10min before it enters normal operation. On the other hand, the drying cylinder is being used. If you want to clean the car, you must be washed with cold water after cooling. If the water bucket in the drying drum is damaged and the condensed water cannot be released, it should be repaired immediately. Prevent drying drum from sucking flat.

When drying fabric, dryer is easy to emit a lot of steam and heat, is high temperature and high humidity machine in printing and dyeing production. Therefore, an insulated exhaust hood must be installed. In this way, on the one hand, the influence of the radiant heat of the drying cylinder on the operator can be blocked. On the other hand, a large amount of wet and hot steam can be discharged from the workshop, which can not only cool down in summer, but also prolong the service life of the plant. At the same time, the design of the plant should also fully consider the ventilation and exhaust and corrosion prevention requirements of the printing and dyeing factory. For industrial hygiene and safe production.
