Weighing mixing system is a kind of production equipment used for processing different powders or liquid materials in a certain proportion automatically and accurately. It is usually composed of weighing system, weighing control instrument, PLC system and host computer.
020-34563445The material trough weighing and mixing system is composed of a large screw conveyor, a small screw conveyor, a stirring mechanism, a material Weighing system, a frame and a silo, etc. After the equipment is started, the stirring mechanism begins to operate to prevent the material in the silo from warping and affecting the continuous conveying of the material. The screw conveyor is composed of a stepping motor, a reducer and a screw shaft with screw blades. The rotation of the screw shaft causes the powder material to move relatively along the screw surface. The material is not rotated together with the screw blades due to the frictional force of the trough or the wall of the conveying pipe, thus pushing the material along the axial direction and achieving the conveying of the material. When the material feeding begins, both the large and small screw conveyors work simultaneously. The operation of the large screw conveyor can enhance the efficiency of material feeding. When the weight of the material in the pallet reaches a preset weight value (the preset weight value is generally set to about 95% of the final weight value of the material), the weighing module sends a signal to the control system, and the control system controls the stepping motor of the large screw conveyor to stop working. At this point, only the small screw conveyor continues to work to achieve the purpose of precise feeding.
Process flow
The material enters the batching tank from the silo, and then is sent into the mixing tank from the reaction vessel. The weight is measured by the weighing module, and the speed of the frequency converter is adjusted according to the actual required flow rate to achieve normal feeding.
After being measured by the plate flowmeter, it enters the feeding box of the screw pneumatic conveying pump and is pushed forward through the feeding mechanism.
3: It enters the mixing chamber and is vaporized by the air at the fan outlet and then sent into the conveying pipeline.
Equipment features
The system is reliable, highly applicable, has high weighing accuracy, high automation accuracy, stable quality and is easy to manage.
The electronic weighing display design ensures high measurement accuracy and is easy to calibrate and maintain
Data processing: The Batching system can automatically perform calculation and processing on the collected signals, thereby automatically controlling the normal operation of the equipment.
The communication function enables bidirectional data communication between the industrial control computer, PLC and instruments.
The monitoring function detects and monitors parameters such as the instantaneous flow rate, daily accumulation, monthly accumulation, and annual accumulation during the batching process.
The screen shows that the operating status of relevant control parameters during the batching process can be displayed through a computer monitor or weighing instrument.
