How to deal with sticking and caking in tannery sludge drying machine

In the drying and dewatering process of high humidity and high viscosity tannery sludge, due to material characteristics, equipment technology and other reasons, it is easy to stick and caking. If this problem is not cleaned for a long time, it will not only affect our drying efficiency, but also shorten the service life of the equipment, thus greatly reducing the use effect of the equipment. So what should we do when encountering the caking in the tannery sludge drying machine? Next, we can have a brief understanding.

1. Choose the tannery sludge dryer with three tube structure (what is the reason for the power reduction of tannery sludge dryer equipment)

The length of rotary harrow three-cylinder multiple-loop tannery sludge dryer is only one third of that of traditional single drum equipment. Due to its small occupied area and convenient installation and disassembly, the site cost is greatly saved. Moreover, the temperature in the cylinder is more uniform, which avoids the problem that the water steam stroke of the single drum equipment is too long and the cylinder end is easy to return to moisture, thus affecting the product quality. The special structure further promotes the drying speed and drying quality, makes full use of the heat energy, so that a large amount of water in the wet sludge is quickly evaporated, thus speeding up the sludge drying speed and reducing the possibility of sludge adhesion.

2. Anti sticking drying process

The equipment adopts the core drying technology of three-stage drying movement, which divides the whole drying process into three drying stages: forward flow drying, counter current drying and reciprocating drying. The steam generated in the drying process is discharged from the end of each stage to prevent the steam from traveling with the material. Through the cooperation of various drying methods, the internal moisture in the sludge can be quickly evaporated to achieve the effect of deep drying.

3. Upgrade in cylinder device

The drum of rotary harrow three-cylinder multiple-loop tannery sludge drying machine is equipped with a "rotary rake crushing" breaking device and a scientifically designed lifting system. The high-speed operation of the device can break the large sludge into fine particles, and under the action of the lifting plate, it can continuously roll, rotate and separate the sludge, so as to increase the contact area between the hot air flow and the sludge, and at the same time, make the sludge drying equipment Work efficiency has been greatly improved.

The above is what to do about the sticking and caking in the tannery sludge drying machine. To prevent the equipment from caking, it is necessary to know more about the drying equipment before purchasing the tannery sludge drying machine. In addition, users are required to adjust and control the equipment according to the operation regulations and do a good job in the maintenance and repair of the equipment. Over the years, ZJN environmental protection equipment Technology Co., Ltd. has been focusing on the research and development of drying technology and equipment manufacturing of high humidity, high viscosity, solid waste and hazardous waste materials. It has more than 100 national patent technologies. If you need help, you can contact our customer service department for further understanding.
