Working principle and equipment advantages of sludge drying machine

Sludge dryer plays an important role in the industrial production process. The paper solves the problems of industrial solid waste sludge produced in the process of production, so as to stabilize, reduce, harmless and resource disposal sludge.

Working principle of sludge drying machine：

The sludge dryer can choose different drying processes according to the characteristics of sludge. The structure of sludge drying equipment produced by Jiaozuo Zhen energy saving company adopts three cylinder sleeves of different diameters embedded together, so that the whole drying process can be divided into three, and the process of each drying stage is different, so that the drying temperature and air flow speed can be adjusted according to the different moisture content of sludge in different drying stages.

Process 1: special crushing and breaking device is used in the inner drum of the equipment, which can disperse, stir and separate the sludge into the equipment, which can not only avoid agglomeration, but also evaporate most of the water in the sludge. Then, it is sent into the middle cylinder of the equipment under the action of special material plate. Process 2: the middle cylinder adopts the reverse flow and vortex drying process, which continues to disperse and lift the sludge, further increase the contact between the material and hot air, so that the water in the sludge can evaporate. Then, it is sent into the outer cylinder of the equipment under the action of special material plate. Process 3: the external cylinder adopts the AC plus reciprocating drying process, which enables the wet to run repeatedly and slowly, and the dry ones first and fast under the action of air volume and special material plate. After the drying requirements are met, the sludge will be discharged automatically.

Advantages of sludge drying machine：

1. Equipment installation

Horizontal layout is adopted, with small floor area and convenient installation and demolition.

2. Equipment control

The equipment adopts automatic control mode, which has high intelligence and simple operation. Only 2-3 people can operate a production line.

3. Equipment production capacity

The equipment adopts three cylinder structure, which not only increases the volume inside the cylinder, greatly improves the processing capacity of the equipment, as well as the production efficiency, but also reduces the production cost of the equipment.

4. Hot air distribution

The distribution device is adjusted by hot air, and the heat air volume in dryer at all levels is adjusted according to the water content, so as to adapt to the fluctuation of moisture content of materials.

5. Material form after drying

The moisture content and particle size of sludge after drying can be adjusted according to the user requirements, which is convenient for the next use;

6. Impact on the environment

The whole system is operated without inflammable, explosive, toxic and short circuit phenomena in the traditional drying machine, and there is no combustion and emission, and belongs to environmental protection equipment.
