The automatic Dosage system consists of depressurized bin, equalized bin and dosage bin. The depressurized bin is equipped with depressurized device, so that the materials entering the equalized bin are not affected by the bin pressure. The homogeneous bin is equipped with stirrer to fully activate the material, avoiding material arching, wall staining and eliminating material dead zone. Due to the uniform pressure in the equalizing bin, it creates conditions for the materials to enter the rotor cavity under the same capacity and weight conditions. The batching cavity is equipped with a horizontal rotating compartmentalized wheel, which conveys the same volume of materials in every turn of the week. The weighing and batching is driven by shaft-mounted reducer and motor, and the motor speed is adjusted by frequency converter, which is controlled by PLC, which regulates the speed of Feeder in real time according to the result of comparing the detection value of instantaneous flow rate with the setting value of flow rate, so that the instantaneous flow rate always tracks the setting flow rate and realizes the purpose of feeding materials in quantitative quantity.

The dosing machine adopts simple transmission structure, adopts variable pitch spiral design, and applies the principle of ejector, so that the working atmosphere at the discharge end of the pump is basically under negative pressure, which effectively solves the influence of pressure change of the material conveying pipeline system on the discharge of the spiral pump; the sealing of the axle end adopts the combination of gas sealing, oil sealing and mechanical sealing, which meets the requirements of oil-resistant, high-temperature-resistant and wear-resistant, and the sealing performance is superior; the wear-resistant material technology, which is under independent intellectual property rights, is applied to the feeder to realize the purpose of dosing. Wear-resistant material technology with independent intellectual property rights is applied to the design and manufacture of the pump to meet the requirements of metering and Batching system with the same conveying capacity. According to the result of comparing the measured value of instantaneous flow rate and the set value, the speed of the batching feeder is adjusted by feedback, so that the instantaneous value always tracks the set value, and the metered product enters the conveying pipeline through the new type of conveying pump. The batching system is controlled by PLC (programmable controller), the signal collected by the load cell is transmitted to the transmitter, processed by the transmitter, and converted into a standard signal (4-20mA) that can be accepted by the PLC to meet the requirements for communication with the PLC.
