V. Description of equipment organization performance
1 , drying tower system and characteristics
The drying unit consists of an air inlet filter system, an air heating and hot air distributor system, a drying main tower, a tower wall jacket air cooling system, a feed and atomization system, a high efficiency cyclone dust removal system, and a tail gas dust collector.
This device has the following features:
- Specially designed volute and hot air distributor: specially designed main tower, hot air volute to ensure that material atomized droplets return to the top, preventing material from returning to top heat
Melt deterioration.
â—† The hot volute adopts a number of spiral-accelerated structures, which greatly enhances the thermal displacement of hot air and material droplets, and the ordered swirling decreases. The hot air distributor also combines the characteristics and requirements of the technology, so that the air deflector is provided on both sides of the distributor, and the angle can be adjusted arbitrarily to control the tangential angle when the hot air enters the tower, and the inner air guiding mechanism increases the hot air. Rotating, strengthening the shear force of the hot air on the atomized film, so that the hot air is in full contact with the liquid, and the heat exchange process between the two is strengthened.
â—† The atomizer adopts a stepless adjustment atomizer, and the rotation speed can be adjusted to the ideal atomization effect.
◆ Adjust the taper of the tower cone, from the conventional angle of 60 ° to 52 °, fully consider the smoothness of the material when the cone is cut.
â—† Designed the lighting device inside the tower and observed the cleaning door and manhole for staff observation and customer visit.
â—† The pipeline adopts quick-load design to facilitate assembly, disassembly and cleaning of equipment.
2 , medium circulation system
The whole machine is composed of a blower, an induced draft fan, a wind regulating butterfly valve and a duct. The delivery and induced draft fans are all supplied by high-quality manufacturers. The cooperation has been for many years and the quality is stable.
3 , air heating purification system
It consists of primary, intermediate and high-temperature high-efficiency air filters, fans and electric heaters.
The heat source is electric heating, the material is all stainless steel, and the automatic temperature control group has high thermal efficiency and stable output heat.
4 , feeding system
â—† The feeding system adopts fuzzy control to automatically match the feeding speed and the exhaust air temperature, avoiding the influence of temperature fluctuation on the dry humidity of the material, and keeping the moisture content of the finished product at the required level, thus ensuring the quality of the finished product.
â—† Peristaltic pump adopts step speed regulation, 4-20mA signal input, matching the outlet air temperature. The main part of the pipeline valve is made of SUS304 stainless steel, which is clean and hygienic.
5 , other auxiliary systems
All of them are supplied by well-known manufacturers and have reliable performance. Some pipelines have been designed with certain angles. The use of pressed stainless steel tubes avoids the phenomenon of material blocking, material blocking, and excessive local resistance.
6 , control system
â—† Siemens products are used by the main control components and programmable devices to ensure the continuous and stable operation of the equipment system. Temperature adopts PID fuzzy control with high precision
â—† Man-machine interface + PLC program control, real-time display of working status, data online collection, system display control temperature, atomizer speed.
â—† The unit control system has high integration degree and high automation level, which greatly reduces the number of on-site operators. It has fault self-diagnosis function, and automatically handles corresponding faults according to different faults in the system, and alarms.
