The horizontal weighing mixing system has the advantages of shorter process flow, higher weighing accuracy, higher reliability, more flexible equipment layout, and significantly reduced plant height compared to traditional powder Weighing systems. According to the different positions of the weighing equipment in the powder vacuum weighing system, various hopper scales and subtractive scales can be formed to meet the different requirements of customers. The mixing scale consists of a feeding station or material storage bin, a vacuum weighing hopper machine weighing device, a PLC controller, and other components, which can complete the automatic feeding and batching of single material by weight or multiple materials with different formulas. Widely used in industries such as pharmaceuticals, food, chemicals, battery materials, building materials, metallurgy, and feed processing. The weighing mixer includes a weighing module and a cylindrical mixing tank set on the frame. The top of the mixing tank is equipped with a feeding pipe, and the bottom of the mixing tank is equipped with a discharging pipe. The mixing tank is equipped with a mixing component, which includes a mixing shaft and multiple mixing blades. The two ends of the mixing shaft are set to rotate at both ends of the mixing tank, and the frame is equipped with a driving component for driving the rotation of the mixing shaft. The mixing blades are arranged in a spiral along the direction of the mixing shaft. The end of the mixing blade away from the mixing shaft is equipped with an arc-shaped scraper, and the side of the scraper away from the mixing blade is in contact with the inner wall of the mixing tank.

The weighing mixer has a mixing shaft consisting of a first shaft and a second shaft, which are rotatably connected together. The first shaft and the second shaft are respectively set to rotate in the mixing tank. The driving component includes a first driving element for driving the first shaft to rotate and a second driving element for driving the second shaft to rotate. The first shaft of the hybrid system is equipped with a sleeve near the end of the second shaft, and the second shaft is inserted into the sleeve and rotated inside it. There are multiple mixing plates on the mixing blades of the weighing mixer along the vertical direction to itself, and the mixing blades extend from both ends of the mixing plates. Multiple mixing plates of the weighing mixer are spiral arranged along the length direction of the mixing blades on the mixing blades. Both ends of the mixing plate of the weighing mixer are equipped with mixing blades perpendicular to its own direction. The bottom of the mixing tank is hinged with an arc-shaped baffle, which is located above the discharge pipe. The scraper contacts the baffle, and the frame is equipped with measuring components for the weighing module. The bottom wall of the mixing tank is inclined downwards towards the discharge pipe.

The application of a weighing mixer in automatic weighing and batching of two types of materials is taken as an example to illustrate the working principle of the powder vacuum load-bearing system. Materials A and B are stored in two silos respectively. The powder vacuum weighing system starts working, the vacuum pump starts, and when the screw discharge valve A at the bottom of the powder silo of material A reaches a certain weight, the screw stops and the discharge valve A closes. The remaining material in the conveying pipe continues to be sucked into the weighing hopper. After suction, the weight of material A in the scale is exactly the set weight. At this time, the spiral discharge valve B at the bottom of material bin B is opened, and the spiral is started. Material B is sucked into the weighing hopper. When material B reaches a certain weight in the scale, the spiral stops and the discharge valve B is closed. The remaining material in the conveying pipe continues to be sucked into the weighing hopper. After suction, the weight of material B in the scale is exactly the set weight. The vacuum pump has stopped. The weighing control system has the advantages of shorter process flow, higher weighing accuracy, higher reliability, more flexible equipment layout, and significantly reduced plant height compared to traditional powder weighing and feeding systems. According to the different positions of the weighing device in the powder vacuum weighing system, various addition scales and subtraction scales can be formed to meet the different requirements of customers.
