Weighing and mixing machine has a powerful software function, which can realize real-time and intuitive monitoring of the production process, management of various formulas, reminder of material shortage, alarm for abnormal conditions and other functions. The machine can be started under the system, and the reactor outputs different signals (fast feeding, slow feeding, unloading, etc.) to PLC at different measuring stages, which can be directly controlled by PLC on the external equipments; push-buttons and switches are installed on the operation table, and the silo can be realized the manual control of the above parts; the weighing and mixing machine is equipped with an emergency-stop button on the field operation and the centralized control table, and the two emergency-stop buttons are in series, which is used for emergency power-off treatment; the weighing and mixing machine is equipped with a stirring motor, which is controlled by the centralized control table. The weighing and mixing machine is equipped with stirring motor controlled by frequency converter. With centralized operation and centralized control, all the instruments can be seen at a glance, which is convenient for monitoring and operation, increases the safety and reliability, reduces the labor intensity of the operator, and eliminates the need for the operator to run between the scattered weighing instruments; the distance between the operation console and the control cabinet is close, and the control signal transmission distance is short and reliable.

Weighing and mixing machine adopts the upper computer monitoring system can not only complete the configuration, debugging, online correction of detection parameters and setting of control parameters, but also realize the collection of production data, the generation and printing of reports, the alarm of abnormal signals and the network distribution of production site information. By using the web function of Configuration King 6.53, the upper monitoring computer can be used as the web server of the Weighing system at the same time, and the Configuration King project can complete the web publishing through the web server. The most important thing in the production process control is to realize accurate control of various materials in and out. Weighing transmitter is used to detect the change of material level in the dosage tank, and the cross-sectional area of the measuring tank is used to get the volume and weight of the incoming and outgoing materials.

Concentrated-phase pneumatic conveying system is recognized as an economical and reliable pneumatic conveying system based on domestic advanced technology and experience, combined with scientific experiments and several years of practice. The system conveys ash with high gas ratio, low gas consumption, low conveying speed, and effectively reduces pipeline wear. The system mainly consists of five major parts: compressed air source, transmitter, control cabinet, conveying pipe and ash storage.

It consists of air compressor, degreaser, dryer, storage tank and piping, which mainly provides high quality compressed air for the transmitter and air control components.

Accepts fly ash from the dust collector hopper and sends it to the ash storage through the conveying pipe after fluidization.

Computerized centralized control of various mechanical components, with a manual operating mechanism. :

Experimentally, the conveying distance can be up to 1300 meters, and the life of the pipeline can be more than 20,000 hours.

It consists of ash storage body, bag filter, vacuum release valve, material level meter, ash unloading equipment and so on.

The positive pressure dense phase transmitter works in four stages:

1、Feeding stage

The feed valve opens, the material falls freely into the sender, when the rising material in the sender touches the material level meter, the material level meter sends out a full signal, the feed valve closes automatically, completing the feeding process.

2. Fluidization and pressurization stage

The air inlet valve opens automatically, the compressed air enters the bottom of the sender, diffuses and passes through the fluidized bed, in the colleague of the material fully fluidized, the air pressure inside the sender rises.

3. Conveying stage

When the pressure in the sender reaches a certain value, the pressure sensor sends out a signal, the discharge valve opens automatically, the fluidization of the material on the fluidized bed is strengthened, and the conveying starts, and the material in the sender is gradually reduced, and the material on the vulcanized bed in the process is always in the side of the flow of flowers while conveying.

4. Blowout phase

When the sender in the material delivery is completed, the pressure drops to the pipeline resistance, the indicator signal, ventilation continues for a certain period of time, compressed air to clean the pipeline, and then the inlet valve is closed, the interval of a certain period of time, the closure of the discharge valve, open the inlet valve, to complete the cycle of a conveyor.
