Working principle of coal feeder (reciprocating coal feeder)

The coal feeder is suitable for the coal-fired furnace pulverizing system of a thermal power plant, which can improve the performance of the boiler under a wide range of load fluctuations, and make the control of the superheating temperature, reheating temperature and pressure temperature more stable, and the fuel and the required air. The quantity is more matched, the required excess air is reduced, the coal is continuously fed, the weighing is accurate, the work is stable, the energy saving is high, and it is the advanced metering coal feeding equipment matched with the coal mill in the coal-fired boiler milling system.

working principle

The coal in the coal storage bin enters the coal feeder through the coal gate, and the conveying metering tape inside the coal feeder is continuously and uniformly conveyed into the coal mill, and the electronic weighing device is installed under the conveying metering tape, and the device is mainly made of high precision. The electronic belt scale is composed of a weighing sensor which generates an electric signal proportional to the weight of the coal and a belt speed signal detected by the speed sensor, and is sent to the totalizer, and the instantaneous flow and the cumulative amount are obtained after the integration.

Structural features

Cylindrical sealing structure to improve pressure resistance and reduce internal dust accumulation;

The ST2 series of electronic belts with excellent performance ensure accurate measurement and long-term stability.

Frequency conversion (or slip) stepless speed regulation, stable operation, energy saving consumption;

The chain scraper cleaning device automatically cleans the dust and residual coal in the machine;

The perfect alarm system can detect and eliminate faults such as coal plugging, coal overload and belt deviation in time;

The high-temperature isolation gate is configured to prevent hot air from flowing back, and has high safety and convenient maintenance.

Vertical Wheelchair Lift

1. The elevator is equipped with landing door, car running direction indicator, mathematical display car, running position indicator and call elevator button at each service landing. When the elevator call button is used, press the up direction button when going upstairs and press the direction button when going downstairs.

2. When the car arrives, the floor direction indicator will display the movement direction of the car. Passengers can enter the car after judging the direction they want to go and confirming that the elevator is normal. Pay attention to the closing of the door leaf and do not stay at the junction between the landing door and the car door.

3. The car is equipped with position display, control panel, door opening / closing button and floor selection button. After entering the lift car, lift and press the floor selection button to go to the floor. To close the car door immediately, press the door closing button. The car floor position indicator shows that you can leave after arriving at the floor and the car door is opened.

4. The rated load of the elevator is limited and cannot be overloaded. Please take the initiative to exit when the personnel are overloaded.

5. The passenger elevator cannot be used as a cargo elevator, and it is absolutely not allowed to transport inflammable and explosive goods.

6. In case of abnormal phenomenon or failure of the elevator, keep calm, call the rescue phone in the car, and do not pry the door without authorization to try to escape from the car.
