Weighing module converts mass (weight) into electricity, which is a mass (weight) measurement method. The output electric quantity signal and the input mass (weight) signal have a single-value linear correspondence, which has the required accuracy and high sensitivity, good frequency response characteristics and less inertia, has little influence on the state of the weighed object, and can work in poor environmental conditions; Good stability, reliability and long service life.

The adjustment of load distribution of weighing module is to reduce the influence of "static uncertainty" of multi-fulcrum balance of weighing platform by adjusting the force consistency of sensors, and ensure the stability of weighing platform support, so as to ensure that the center of gravity of weighing platform deviates without bearing capacity, and to ensure the accuracy of weighing instrument and relevant metering performance requirements.

The precondition of load adjustment of weighing module is mainly to check and adjust the installation quality of each component of weighing instrument, meet the technical requirements specified in technical documents such as technical standards, verification regulations and construction drawings, and put forward the necessary components and characteristics requirements. For the newly installed weighing instrument, all components should be thoroughly inspected.

In addition to meeting the performance indicators required by the weighing instrument, the selection of weighing sensors should try to use sensors with consistent output sensitivity and input impedance, and connect them correctly in the wiring compensation box. The wiring compensation box shall be installed near the weighing instrument in the metering room.

The weighing module, pressure transmitter, level gauge, position switch on the pneumatic valve, air source pressure gauge and other components in the ton bag automatic mixer are used to detect and monitor the working conditions. For multi-bin conveying, the three-way valve can be controlled by the touch screen to make bin selection judgments. When the multi-bin pump conveys a single bin, to prevent material backflow, a shut-off valve needs to be installed above the receiving bin.

The Weighing fully automatic mixer adopts an industrial computer with high protection level as the main control computer of the system, and a special filter screen is used in the computer ventilation and heat dissipation system, which can be cleaned or replaced regularly and can effectively remove the influence of dust in the air on the equipment. The weighing system is input into the computer system through the man-machine interface or computer network, and the computer control system automatically calculates the supply ratio of each raw material according to the detection data and the process formula, and then the PLC control system synthesizes the supply speed of each raw material supply system to accurately and continuously complete the raw material ratio according to the process sequence.

The Positive pressure weighing mixer achieves the requirement of batcher control precision and reduces the cost as much as possible through the dosage ratio of each raw material. According to the difference of each batch of materials and arbitrary change, optimize the calculation table input database using the development of visual man-machine interface, read the calculation data and display in the interface, visually create the database application program, make the application of the database more convenient and flexible, while supporting the application of network environment.

The Fan weighing mixer installs a module at the bottom of the silo, and ensures the normal operation of the whole system through the precise control of the electrical program. The control objects in the pneumatic conveying of positive pressure pulse material and acid are the exhaust valve, feed valve, discharge valve, pulse gas knife valve and inlet valve in the silo. The control mode is controlled by Siemens programmable controller, and the solenoid valves and motors are controlled by the operation of Proface touch screen, contactors and intermediate relays, which is convenient for debugging and maintenance.

The Pulse Width automatic mixer is equipped with an activation hopper and gasification at the bottom of the storage bin. When discharging, the activation hopper vibrates continuously and the gasification purging ensures the smooth falling of materials, and the eccentric vibration module can be used to adjust the vibration amplitude to improve the efficiency and gasification purging frequency. When conveying materials, the conveying capacity and conveying efficiency can be changed by adjusting the air time and material time of the air knife valve, which is helpful to meet some links with high requirements for crushing rate. The pulse interval and pulse width can also be adjusted to avoid dust leakage in the storage bin during transportation.
