The role of rotary feeder in pneumatic conveying and its application in different industries

The rotary feeder can continuously and evenly feed the dry explosive powder material or small particle material in the upper silo of pneumatic conveying to the next equipment, which is a quantitative feeding equipment. The rotary feeder is suitable for powdery materials and granular materials. Widely used in environmental protection, metallurgy, chemical industry, food, food and other industrial sectors.

The rotary feeder adopts an elastic rotor, which has better sealing performance and ensures uniform feeding. As a conveying device in a pneumatic conveying system, it includes a machine base, two frames, a central shaft and an impeller. The machine base has a feed port and a discharge port respectively. It is characterized in that an anti-card device is provided at the feed port. The B surface of the anti-card device coincides with the machine base cavity. The anti-card device has a rectangular groove with a depth of 1-2cm, which extends upward from the center and communicates with the feed port. In order to prevent the anti-jamming device from impeding the feed rate, the surface corresponding to the B surface is designed to have a shape like a triangle. During use, when the impeller is wrapped with impurities and runs to the anti-card device, the impurities are stripped off by the fast opening action of the groove on the device, and moved from the groove to the feed port through the inertia action to enter the rotary feeder again In the cavity, the normal operation of the rotary feeder is ensured.

With the integration of refining and chemical equipment and the large-scale refining and chemical equipment, the production process for the instrument and control system accuracy and adaptability requirements more and more stringent, as the core components of the control system to implement the rotary valve, its performance and quality for the petrochemical plant economic benefits of the impact of more and more.

Powder conveying, dynamic conveying. For the blending system in the refinery, in order to improve the quality of the blending, it is often required that the various oil products involved in the blending must be injected and cut off accurately and at high speed, which often requires the use of a rotary valve with a higher cut-off rate to provide accurate liquid blending regardless of the flow rate of each flow path.

Conventional straight-trip or shut-off valves are no longer suitable for such applications in refineries. Rotary valves, by virtue of their own advantages as described above, can provide a higher cost-performance ratio in such applications. To the user's long-term operation to bring greater benefits.
