brief introduction
Rotary feeding valve, also known as rotary feeder, is a special equipment used in powder (powder foam, particle material, powder mixture) conveying system for discharging, metering, dust removal, quantitative conveying, mixing and packaging. It is mainly composed of three parts: main valve, deceleration mechanism and protection device. The main valve is composed of shell, end cover, impeller, bearing, oil seal, gas collector, etc. The elaborate structure design makes the rotary feeding valve have good air lock, high temperature and high pressure resistance, anti jam and other special functions. It can be used in chemical industry, environmental protection, petroleum, metallurgy, refractory, electric power, cement, plastics, food, medicine and other industries. It can also be equipped with mixing acceleration chamber, three-way reversing valve and plug valve, which can be used in pneumatic conveying system and dust removal system.
characteristic
1. The overall structure design is firm and compact, exquisite and beautiful;
2. Through the design and treatment of special structure, the shell and impeller can transport special materials such as high temperature, high pressure, high hardness, high viscosity, easy to produce static electricity, ultra-fine and so on;
3. High machining accuracy, which can ensure minimal clearance;
4. The inlet and outlet section of the shell is special, which can effectively prevent the extrusion and crushing of granular materials;
5. The shell is designed with exhaust passage and exhaust pipe interface for balancing pressure, which can improve work efficiency and avoid material accumulation;
6. The polishing precision can reach 400 ×, which is suitable for conveying food grade and drug grade materials;
7. Cycloid pinwheel reducer drive, equipped with inverter or CVT to realize quantitative or variable transmission; When zero protection function is needed in special applications, sensors can be easily configured at the end of rotary feeding valve to realize on-line monitoring and on-site monitoring.
