Overview of pneumatic conveying material sealed pump The material sealing pump is
also called pneumatic conveying material sealing pump, low-pressure continuous conveying pump, powder conveying pump, etc. It uses Roots fan as the power source. It consumes more than 40% energy than the air compressor system. The system operates without valves frequently. Action, low conveying flow rate, low pipe elbow wear, long service life, low operation and maintenance costs, small equipment size, low installation height, and multiple ash buckets. After collecting in a chute, it is transported by a continuous pump. The number of equipment is small, the operation and control are simple, the investment is low, and the system operates reliably.
Pneumatic conveying material sealing pump is mainly based on the nature of the material itself, such as particle size, density, viscosity, etc. If the viscosity is too large, it is not suitable for pneumatic conveying. That is, the material characteristics, conveying distance, and conveying process determine whether the pneumatic conveying method can be used. For example, quartz sand, lead powder, and other metal powders are heavier, the conveying distance is more than several kilometers, and the conveying output is hundreds of tons per hour.
Working principle of pneumatic conveying material sealed pump
The material seal pump (pneumatic conveying system) is a combination of the principle of pneumatic pressure and jet flow technology and fluidization technology, which fully absorbs the theory of modern pneumatic conveying two-phase flow. After many years of operation and practice, it is aimed at the powder pneumatic conveying process. A large number of special equipment developed for the characteristics of continuous transportation at medium and short distances. The low-pressure air from the air source passes through the regulating valve (or pressure reducing valve) butterfly check valve, movable air pipe, and nozzle into the pump body diffusion chamber. When powder or granular materials fall from the falling hopper into the nozzle and expand the pressure When the high-speed air flow area between the devices is blown away. Coupled with the gasification effect of the bottom gasification device, the material is gasified into a suspended state. After that, it is sent into the condensing tube of the diffuser by the high-speed airflow, flows through the throat diffusion tube, enters the conveying pipeline, and is sent to the required discharge point (for example, in the warehouse) to complete the feeding process.
Under normal circumstances, the material sealing pump is more suitable for the bottom of the silo, and the material is dropped smoothly. If it is not on the bottom of the library, it can be placed next to it. But the oblique angle of the blanking tube is ≥450. If installed in the lower part of the dedusting hopper, one bucket, one bucket, or two inclined pipes can be used; in special cases, four buckets, four inclined pipes can be inserted into a material-sealed pump, but the inclination of all the ash falling inclined pipes Both should be ≥450. Before running, a proper amount of oil should be added to the movable duct box to lubricate the oil seals at both ends of the movable duct. Add the appropriate amount of mechanical oil to the position of the oil standard line in the reducer of the adjustment mechanism. In winter, N46 and summer N68, change the oil within one month after the initial operation, and then generally change it twice a year.
