SN2 Weighing Hopper

Weighing hopper machine detects and samples the weight of material in the metering hopper by the controller, and stops feeding when the weight of material in the metering hopper reaches the upper limit value set for dosage. It reads the main totalization, instantaneous flow rate, set flow rate, weighing instrument status and other related data from the weighing instrument. Weighing instrument status display (zero state, interval state, running state or alarm state), online monitoring and management by computer, with high requirements on weighing speed, weighing accuracy, system compatibility and expandability.

Automatic batching machine can continuously and automatically complete the weighing and quantitative batching, automatic conveying control and other operations for powder, granule, block and bulk materials in various industrial production environments. It is mainly used to batch small mixes and various powders and miscellaneous materials according to the ratio given by the technology center into the batching silo after a batching process, and the spiral high-speed cylindrical stirring bar stacks the ash to the external discharge port while mechanically stirring, and in order to ensure the humidifying effect of humidifying mixing, it To ensure the humidifying effect of humidifying mixing, 0.6-0.9MPa medium-pressure water is used as the water source of humidifying mixing, and the atomization effect when the water pressure passes through the nozzles of humidifying mixing is better, which is conducive to full wetting; at the same time, a filter is installed on the water inlet pipe of humidifying mixing, to prevent the nozzles of humidifying mixing from being clogged; a ball valve is installed in front of each nozzle, and a shut-off valve is installed in front of and behind the pipeline filter in the water inlet pipe. The ball valve in front of the nozzle is used to adjust the water volume of the nozzle, so that the humidifying mixer has the best humidifying effect. Once the ball valve in front of the nozzle is adjusted, it will not be closed under normal circumstances, but the shut-off valve on the main pipe will be used to cut off the water supply, and a shut-off valve will be installed before and after the water inlet main pipe filter to facilitate the regular cleaning of debris in the pipe filter.

The ratio of the ingredients is the most important part of the whole dosing process, directly related to the quality of the mix. According to the chemical composition of the raw materials used in the small mix, will be similar to the composition of a variety of miscellaneous materials mixed together with mixing, mixing process, used to match the lower miscellaneous materials, raw materials mixed into a material, occupying a batching silo, saving the use of batching silo, shorten the raw material field batching discs of the change of warehouse time and the spiral transportation pressure, to ensure that the amount of material under the disc to improve the quality of the mix. It plays an important role in stabilizing the mixing quality and optimizing the raw material structure.

Application of liquid pumping and mixing batching system
The batching system adopts dual CPU to form a redundant system, and the STEP7MicroWin V4.0SP6 programming software provided by Siemens is used as the man-machine interface to write debugging programs and download programs. The PC and PLC experimental machine are connected by a PC/PPI cable for communication, and the corresponding parameters are set.
Powder Dosing System Design
The automatic dosage system consists of an industrial grade control computer, programmable controllers, and electrical control boxes, and is designed to meet the needs of a maximum number of silos and platform scales for mixing, weighing, and mixing control.
Application of weighing device in automatic glue dosage system
The automatic dosing system can realize the full automatic control of the glue making, glue delivery and glue using process. According to the pre-set ratio and process, the deviation in the dosing process is monitored through the screen, and the dosing ratio behind is corrected according to the ratio of the formula, so as to ensure the accuracy of the formula.
Screw dosage system technology application
Screw automatic dosage system is the ideal equipment for continuous dosage and measurement of bulk materials, which can set high, middle and low feeding, and then control the feeding speed of screw feeder, so as to achieve the purpose of accurate dosage. According to the actual process of batching process, it reflects the operation status of feeding, batching, feeding and related equipment in the form of dynamic screen.
Automatic Powder Batching System
Batching system in the field of powder processing and treatment, the leading technology of powder processing equipment absorbed and optimized in the weighing and mixing machine in accordance with the production instructions and formulas, a variety of materials will be placed, transported to the set station, using automatic walking weighing mechanism, a variety of materials accurately and proportionally added to the barrel.
Reactor feeding and dosage system realization
Reaction kettle feeding dosage system through the explosion-proof electronic weighbridge direct collection of weight signals, automatic control of weighing, the operator through the keyboard or the mouse in the upper computer human-machine interface (HMI) on the input charging information (charging type, weight, etc.), monitoring the whole process of charging control, printing the results of the charging and production reports, to achieve the process of charging the measurement and control of the integration of the management, is not lost as a practicable and effective method.
