How to ensure the drying quality of printing and dyeing sludge dryer

Printing and dyeing sludge comes from the by-product of wastewater treatment in textile printing and dyeing enterprises. In the process of dehydration and drying, printing and dyeing sludge with high water content and high viscosity is prone to stick to the wall, uneven drying, moisture regain at the end, slow drying speed and low output, especially after the printing and dyeing sludge dryer runs for a long time, it is difficult to guarantee the drying effect of the equipment. Therefore, in order to ensure the drying quality of materials, we need to strictly control the drying quality of materials from the following aspects. So how to ensure the drying quality of printing and dyeing sludge dryer?

一、 Selection of qualified printing and dyeing sludge dryer to meet production demand

The drying effect of materials is inseparable from the quality of printing and dyeing sludge dryer. Printing and dyeing enterprises need to select suitable equipment for their own production from the actual drying needs such as material characteristics, drying output, site size and moisture content requirements. In this process, we need to pay attention to the material, technology, manufacturer strength and after-sales service of the equipment. The equipment with good quality not only has good working performance, convenient operation, but also has low failure rate, which can guarantee the drying effect of materials to a large extent.

二、 Daily maintenance and cleaning of sludge dryer

As a large-scale machinery, printing and dyeing sludge dryer needs daily maintenance in the long-term use process. This is to avoid equipment failure and various problems. Daily maintenance and cleaning of sludge dryer can effectively guarantee the drying quality and output of materials.

1. Clean up regularly. The drying process of heat and mass transfer between material and hot air is completed in the cylinder of the printing and dyeing sludge dryer. Therefore, after each operation, there is no material left in the equipment. If the dust and residues of the equipment cylinder are cleaned regularly, the real sample can prevent blocking during drying and enhance the drying quality of materials.

2. Note that the spare parts are in good condition. The normal operation of printing and dyeing sludge dryer is inseparable from the interaction of various parts, so we should pay attention to the condition of various parts when checking the equipment. If there is rust or serious pollution, it needs to be treated or replaced in time to ensure the efficiency of the dryer.

3. Ensure that the lubrication is in place. The flexible operation of machinery is also inseparable from lubricating oil lubrication. Fully lubricated equipment is more flexible, and the production performance will be improved accordingly. If the equipment is not lubricated enough for a long time, it will not only affect the drying of materials, but also easily damage the equipment parts. Pay more attention to these problems, strengthen the protection of the sludge dryer, can effectively extend the service life of the equipment.
