Pneumatic conveying equipment is a device that conveys powdery granular materials by means of positive pressure pneumatic conveying. Commonly used models are sfj75, sfj150, sfj200, etc. The conveying pipeline can be arranged according to the specific terrain to achieve centralized, dispersed and high-level conveyance. The medium is completely sealed, and the transportation process is not affected by climatic conditions, which can ensure that the materials are not affected by moisture, which is conducive to production and environmental protection. Through long-term operation, it has been proved that its performance is stable, its quality is reliable, and it is free of dust pollution. It is an ideal pneumatic conveying equipment. Pneumatic powder conveyor, also known as sfj high-efficiency and low-consumption powder conveyor, is widely used in power plant to transport fly ash, ...

I. Brief Introduction of Pneumatic Conveying Material Sealed Pump in Power Plant:
Second: the advantages of material seal pump
1. Equipment investment is small. One material-sealed pump can replace two warehouse pumps, reducing equipment investment.
2. The gas pressure of the material seal pump is 0.04Mpa-0.1Mpa, which reduces the gas supply pressure, saves air consumption, and reduces the motor power.
3. Reduced maintenance costs. After the system is installed, commissioned and put into operation once, it basically needs no operation, and there is almost no maintenance. The maintenance workers only need to check regularly.
4. Low pressure conveying, the equipment has good sealing performance, reliable operation, no pipe blocking phenomenon, and perfect environment
Since the equipment was put on the market, it has been proved by many uses that the pump has a smaller volume and lower air pressure (0.2--1 atm.). It can be equipped with a fan), easy to arrange, no dust, and meet the requirements of environmental protection. It is widely used in electric power, building materials, chemical industry and other fields. It is an ideal equipment for lifting and conveying powdery materials such as cement, raw materials and fly ash within an equivalent distance of 680m and a height of 50m. The main feature of this material-sealed pump is its long service life. Reliable operation, almost no maintenance and wear parts.
Three: Material sealing pump works
The material seal pump uses the air jet effect to make the air drive the ash particles to send the ash to the ash warehouse. The material seal pump mainly consists of four parts: nozzle, cylindrical pump body, nozzle adjustment device, bottom vaporization device, and the material seal pump works. The energy of the time comes from two parts: one is the kinetic energy of the fan, and the other is the potential energy of the material column. The material column is high, the potential energy is large, the pressure is large, and the conveying capacity is correspondingly large, otherwise it is small.
The material seal pump maintains a certain material level during normal operation. When the amount of material under electrical dust collection increases in a short time and the material seal pump is still working normally, the material level height naturally rises. As the material level increases, the material pressure increases. The increase of large potential energy will increase the corresponding amount until the system automatically balances. When the amount of material under electric dust collection is reduced in a short time and the material sealing pump is still working normally, the material level height will naturally decrease. As the material level height decreases, the material reduction potential energy decreases. The corresponding delivery volume is small until the system automatically balances.
Four: Operating conditions of cement conveying pumps
1: The necessary condition for the normal operation of the material seal pump is that there must be a certain material seal height. The pressure of the silo material level must be greater than the positive pressure when the material seal pump is working. The positive and negative pressures are separated by the material level pressure. Press to send the material away, so a certain level of material height is necessary.
2: The dust collector must be installed on the receiving warehouse. The exhaust air volume of the dust collector must be greater than the inlet air volume of the ash conveying fan. Otherwise, when the inlet air volume is greater than the exhaust air volume, the pressure in the receiving warehouse is forced to increase, causing the system pressure not to increase. Equilibrium, the pipeline resistance is large, and the inlet air blows back from the material sealing pump to the part above the silo, so that the material sealing pump cannot work normally.
Five: Selection principle and applicable conditions of low pressure pneumatic conveying pump
Pneumatic conveying pump, also known as SFJ high-efficiency and low-consumption powder conveyer, is widely used in power plant conveying fly ash, cement factory conveying cement, alumina plant conveying alumina powder, pneumatic conveying raw meal powder, kaolin conveying, limestone powder spray conveying, mining Transportation of powdery materials such as powder transportation, antimony powder transportation, sawdust transportation, rice hull transportation, straw particle transportation, and food-grade material transportation.
Features of powder material conveying pump
1. Equipment investment is small. One powder conveyor can replace two or four warehouse pumps, reducing equipment investment.
2. Low pressure conveying, working pressure 0.02-0.1MPa, small pipeline wear, good equipment tightness, reliable operation, no blockage and leakage, and long service life.
3. Energy saving and consumption reduction. Roots blower is used as the air source (the existing compressed air power source can also be used, and the central air source provides centralized air supply to multi-system equipment), and the power consumption is small. After the system is installed, commissioned and put into operation once, it basically needs no operation, and there is almost no maintenance. The maintenance workers only need to check regularly.
4. The pneumatic conveying scheme selected by Gongyi Tianze Machinery Equipment Co., Ltd. is reliable, simple, economical, practical, and highly automated. It has a large number of achievements throughout the country. Representatives of the units used are: China Huaneng, China Huadian, and China Aluminum Branches, China Resources Thermal Power, Zoomlion Cement, as well as leading enterprises in various regions and local large and medium-sized power plants, chemicals, cement, medicine, etc.
