On the powder delivery process and its measurement batching system
Powder Engineering contain ingredients from a variety of raw materials by mixing the corresponding processed into semi-finished and finished the whole process, generally
consists of warehousing systems, conveyor systems, batching systems, hybrid systems, automatic filling system and the central control system. Among them, conveyor systems,
batching systems, hybrid systems are key elements of the production.
The transport links, since the powder itself, such as: flow, bulk density, moisture, viscosity, particle size, the uncertainty with static electricity, destined to the
transport process of the powder has not perfect solution. Coupled with some of the powder material also has a flammable, explosive, toxic, hazardous and other special
properties, making it more difficult to transport the powder to get a good solution, which is tied interference enterprise technology improvement and enhancement of product
quality is a problem, even affect the development of enterprises.90 degree conveyor
For measuring ingredients, since most companies use artificial ingredients, feeding mode of production, likely to cause dust emissions, and pollution of the environment
affect the operator's physical health, but also restricts the development of enterprise modernization process. And widely used in chemical industry, transportation and
counterweight pressure tank combination, although the transport capacity, long distance transport, logistics and continuous transmission, and high-speed delivery of objects, but
can not solve the pipeline due to the emergence of plot material clogging phenomenon, while the transmission pipeline quality requirements are very high, both to wear, but also
anti-static, and the equipment is complex, cumbersome, difficult to install, because the materials and equipment wear serious, equipment investment and running costs are more
expensive . Relatively speaking, the way the metering screw counterweight has more technical advantages. Using screw metering device, its measurement accuracy is higher, in the
transportation process does not appear the phenomenon of clogging materials, food, fine chemical industry used a relatively common form of measuring transportation mode. But the Telescoping conveyors
drawback is inconvenient to install, easy to clean. Measurement of vibration transportation, guaranteed throughput and a large measurement accuracy, because the equipment area
of large, easy to install, and conveying distance is greatly restricted, and thus also in the use is greatly restricted.
How to solve the powder delivery process of these difficulties it? Some international professional Powder Engineering Company mainly uses positive pressure conveying +
counterweight cans, screw metering counterweight + vacuum conveying and vacuum conveying + mixing tank of the process. Beijing Lai Mite developed vacuum conveying + mixing tank
in this way in recent years been used by many foreign companies a new combination, it is through the counterweight tank measuring instruments and vacuum conveying equipment
linkage and full use of PLC control system, an effective solution to the powder delivery process, many problems exist, with low power consumption, low cost, low maintenance and
so on. Measured with high precision measuring instruments, both for accurate metering, dosing conveying tasks, but also effectively protect the environment. The successful
operation of the system, in order to fully enclosed automatic batching, conveying system and application widely played good role in promoting.
