With the increasing production of sludge, many friends have started to pay attention to low-temperature sludge drying equipment. This equipment can be used for sludge dewatering and drying in industries such as electroplating, metal processing, textile, printing and dyeing, municipal, sewage treatment, pharmaceuticals, leather, etc. By using low-temperature sludge drying equipment to treat high humidity and high viscosity sludge, waste can be turned into treasure, with high comprehensive utilization value, bringing economic and environmental benefits to customers. It should be noted that the price of a low-temperature sludge drying equipment is not cheap, usually ranging from hundreds of thousands to millions. If the maintenance is not good, it may damage the service life of the equipment, especially in cold winter, and it is even more important to pay attention to the maintenance of the equipment. This article introduces how to extend the service life of sludge drying equipment under low temperature conditions in winter.
1. Turn on and off the devices in order as needed.
When starting, the operator should strictly follow the operating instructions provided by the manufacturer to open the equipment on the production line. Before drying, pay attention to preheating. When the drum temperature of the low-temperature sludge drying equipment rises to a certain extent, it can be loaded again. When shutting down, it is also necessary to comply with relevant regulations. Firstly, close the feeding device and allow all remaining sludge in the drum to dry and discharge from the drum. Then, turn off the heating equipment and allow the drum to rotate continuously until the temperature drops evenly before shutting down. The purpose of doing so is to avoid cylinder deformation caused by local high temperatures.
2. Do a good job in anti freezing work.
Due to the cold winter, especially at night, the temperature can reach minus ten degrees Celsius, and relevant measures need to be taken to prevent freezing.
On the one hand, it is necessary to prevent sludge from freezing, stack it indoors and cover it as much as possible to avoid increasing the difficulty of drying; On the other hand, to prevent the sludge drying equipment from freezing at low temperatures, key parts can be replaced with antifreeze lubricants to avoid freezing.
3. Do a good job of cleaning and inspection.
To prevent residual wet mud from freezing and causing damage to the equipment, after the low-temperature sludge drying equipment is dried, the cleaning work can start after the cylinder is fully cooled, especially for the sludge residue in the feeding equipment and dead corners inside the cylinder. In addition, the low-temperature sludge drying equipment should be regularly inspected, and if there are any faults in the equipment, it should be promptly inspected and repaired.
