This product is the second-generation paddle dryer developed and designed by the company, and it has different forms such as disc, semi-disc and spiral structure.
◆ The equipment has a compact structure and a small footprint. The heat required for drying is mainly provided by the wall of the hollow blade arranged on the hollow shaft, and the heat transfer of the wall of the jacket only accounts for a small part. Therefore, the heat transfer surface of the unit volume equipment is large, which can save the equipment area and reduce the capital investment.
◆High heat utilization rate. The sludge dryer is heated by conduction heating, and all heat transfer surfaces are covered by materials, reducing heat loss; the heat utilization rate can reach more than 85%.
◆The blade has a certain scrubbing ability, which can improve the heat transfer effect of the blade. The dispersion force generated by the combined movement of the inclined surface of the rotating blade and the particle or powder layer makes the sludge attached to the heating inclined surface have a cleaning function. In addition, due to the reverse rotation of the two-axis blades, alternately segmented compression and expansion and stirring functions, the heat transfer is uniform and the heat transfer effect is improved.
◆ It can realize continuous and fully enclosed operation, reducing labor and dust emission.
◆ The exhaust gas treatment system generally adopts two forms of normal pressure or negative pressure. According to different conditions, the exhaust air volume is reduced as much as possible, thereby reducing the cost of exhaust gas treatment. The odor of sludge evaporation can be treated by another deodorizing system and discharged after reaching the standard.
Key technological innovation and improved design：
◆ The company absorbed foreign disc blade technology concepts, innovatively designed the second-generation double-shaft or four-shaft structure, and has been put into production and application in large quantities;
◆ The overall design of the bearing seat and overall machining, optional additional cooling device;
◆The cylinder, bearing and shaft are all designed for thermal expansion and sliding freely, and the overall frame design of the main engine;
◆The overall enhanced design, the strength and service life are more guaranteed;
◆The blades of the propeller are welded as a whole, with better strength; the scraper can be added according to the state of the material, and the cutting and dubbing performance is better;
◆ The structure design is more compact, and the area of a single blade can be designed for a large blade dryer ≤ 500m2;
◆The direct drive structure design, the operation is more balanced, reduces the swing and tightness caused by the chain drive;
◆ The unique processing and assembly technology of Jinling Company ensures the concentricity of the equipment and the sealing performance at both ends is better;
◆According to different conditions, the semi-circular tube jacket heating and the integral jacket heating type can be designed;
◆ According to the material requirements, different discharging forms can be designed to ensure the drying residence time of the materials and further improve the overall efficiency;
◆ Special anti-bridging feeding design.
