Njgc-30II pressure-bearing weighing fully closed feeder is mainly used in the pulverizing system of circulating fluidized bed boiler in thermal power plants. It is a pressure-resistant, energy-saving and environment-friendly weighing feeder, which can not only transport coal evenly and continuously, but also measure coal consumption in separate furnaces. It is an ideal equipment for balancing calculation of coal consumption in reality.

There are mainly closed box, transmission system, cleaning system, metering system, temperature control and other protection systems, electric door and electrical control system. And can be extended according to the implementation scheme.

1. Fully closed pressure-resistant cylindrical structure, with suburbs to prevent dust overflow, can ensure on-site civilized production;

2. According to user requirements, the rack can also be designed to be pulled out of the box for maintenance and overhaul;

3. With deviation adjustment and anti-deviation structure, it can ensure the normal and stable operation of conveying;

4. The use of the company's electronic belt scale, to ensure accurate measurement and long-term stability;

5. The weighing display instrument has an optional rs-232c /485C communication interface;

6. The optional variable frequency stepless speed regulation runs smoothly, not only saving energy and reducing consumption, but also meeting the requirements of on-site open-loop or closed-loop regulation for different flow rates;

7. The chain scraper cleaning device can automatically clean the dust and foreign matters in the machine;

8. The perfect alarm system can timely find and eliminate the faults of coal blocking, coal breaking, coal passing, ultra-mild belt running off track, etc.;

9. The measuring part of the weighing and feeding machine is ZN2105 belt scale, which has a short measuring distance, a sampling frequency of more than 100 times per second, strong anti-interference, in the use of the coal feeder, dust and the surrounding electromagnetic field is strong, anti-interference is particularly important.

10. The high temperature isolation gate can prevent the backflow of hot air and provide convenience for safe production and maintenance;

11. It can be linked with remote DCS system to realize intelligent control.
