Market Status of Powder Conveying and Dosing System
Because most companies use the lean production method of manual service seasoning and feeding, it is very easy to cause smoke and dust to fly and pollute the environment, affecting physical and mental health, and also hindering the company's intelligent development trend and system process. The method of positive pressure powder conveying and balance block tank fusion applied in the petrochemical industry, although the transportation capacity is large, the transportation distance is long, the freight logistics can be transported continuously, and the blocks can be transported at a high speed, but it cannot handle the gas pipeline. The blockage caused by the accumulation of materials has very high requirements on the quality of the conveying pipeline. It is not only wear-resistant, but also anti-static, and the machinery and equipment are complicated and heavy, and the installation is difficult. The damage to raw materials and machinery and equipment is relatively serious. Therefore, the capital investment and operating costs of machinery and equipment are relatively expensive. Relatively speaking, the method of measuring and verifying the balance weight of the screw rod has more technical advantages. The screw rod metrology verification equipment is selected, and its metrological verification precision is high, and it is not easy to block the raw materials in the whole process of transportation. But the disadvantage is that it is not easy to install and not durable. The method of vibration transportation measurement verification ensures a large air supply and the necessary measurement verification accuracy. Because the batching system equipment occupies a large area, it is not easy to install, and the seasoning transportation distance is limited by a large level, so the system software is applied in the application. also suffered considerable restraint. Some international technical professional powder equipment steel structure design projects mainly use positive pressure transportation + balance block tank, screw metering verification balance block + air pressure transportation, and air pressure transportation + automatic batching tank production process. The method of air pressure transportation + batching tank is a new composition method that has been selected by many overseas companies in recent years. The automatic control system of the whole line has reasonably dealt with many problems in the powder conveying and processing technology, and has the advantages of energy saving, low cost and low maintenance. Equipped with metrological verification instruments and equipment with high metrological verification precision, it can not only carry out the daily tasks of metrological verification, automatic seasoning and transportation, but also reasonably protect the ecological environment.
