The Discrete vacuum mixer runs Siemens WINCC monitoring software through the computer, communicates with the two communication ports of the programmable controller through their respective communication ports, and backs up each other. It can dynamically display the process flow of the entire production process, display the operation, failure and alarm status of each equipment, and display process parameters such as temperature, pressure, etc. And can set such as alarm value, timing parameters, weighing instrument parameters.
020-34563445The Weighing system of the discrete vacuum mixer is an electromechanical integrated system that integrates automatic control technology, measurement technology, and computer management technology. It has the advantages of weight value digital display, dynamic process screen display, formula modification and management, fast ingredient speed, and high control accuracy. Adopting a complete screen Batching system on the upper computer, it has functions such as automatic storage of batching data, query of batching process list, statistics and printing of shift, daily, monthly, and annual reports. Adopting an open control mode, with strong compatibility and an open database. The factory level local area network can be connected through Ethernet to achieve integrated management and control. The weighing Feeder achieves the required precision of ingredient control and minimizes costs by proportioning the amount of each raw material. According to the different batches of materials, the calculation table can be optimized and input into the database using the WINCC visual human-machine interface. The calculation data can be read and displayed in the interface, and a database application can be created visually to make the application of the database more convenient and flexible, while supporting network environment applications. The weighing and batching machine is equipped with a weighing module at the bottom of the silo, which is precisely controlled by an electrical program to ensure the normal operation of the entire system. The control objects of the positive pressure pulse acid pneumatic conveying process are the exhaust valve, feed valve, discharge valve, pulse gas knife valve, and inlet valve in the silo. The control method is controlled by a Siemens programmable controller as the control source, which controls various solenoid valves and motors through Proface touch screen operation, contactors, and intermediate relays for easy debugging and maintenance.
The weighing mixer uses a hopper scale PLC、 The ingredient hopper and weighing scale can be disassembled and connected. Before transportation, each module can be disassembled and transported. After arriving at the destination, they are installed as a whole. During mixing, different raw materials at different heights of the mixing arm will be mixed while mixing, forming a multiple single mixing and multiple mixing effect, greatly improving the efficiency of raw material mixing and making the mixing of raw materials more uniform. The mixing head is set on the inclined surface of the mixing hopper to allow the raw materials to move towards the mixing head under the action of gravity. Compared with the horizontally set mixing head, the inclined set mixing head moves the raw materials towards the mixing head under the action of gravity during mixing, so that the top raw materials can be stirred, reducing the energy consumption of the mixing head and improving the mixing effect. There is a driving motor installed below the weighing mixer, which is connected to the screw rod to transport the raw materials from the feeding hopper to the explosion-proof weighing scale. The discharge end of the electronic weighing scale is equipped with a discharge valve, which includes a driving air rod, a valve, and a rack. The valve is equipped with a rotating gear, which meshes with the rack. The driving cylinder drives the rack to move and then drives the rotating gear and valve to rotate to open or close the valve. Multiple universal wheels are installed below the storage hopper for easy transfer.
Description of the main functions of the feeding system
