Low pressure pneumatic powder conveying pump - powder conveying machine  

Product introduction:
SFJ low consumption powder conveying machine belongs to a low pressure ash material sealing pump, named because of different local users' calling habits, the professional name is called "material sealing pump", this product is our factory on the basis of the introduction of foreign advanced technology, aiming at various problems existing in different types of pneumatic conveying equipment in China and building materials institute cooperation and developed a new low pressure pneumatic conveying pump. The product is widely used in power ash removal, cement homogenization and reverse storage, all kinds of powdery material transportation, low consumption, completely closed, no maintenance, air source can choose Roots fan, compressed air.
Working principle:
The material transported through the bin into the pump body, the material in the pump body through the lower fluidization gas box fluidization compressed air through the main air pipe through the nozzle into the diffusion mixing chamber at high speed, the fluid material in the pump body in the bin material pressure and the negative pressure of the nozzle into the diffusion mixing chamber mixed with the air flow, the air flow carried along the pipeline to the discharge point (inventory).
Problems existing in single bin pump and negative pressure transportation of fly ash:
1, power consumption, serious wear
As the bin pump adopts 0.4mpa-0.6mpa high pressure gas supply, the elbow pipe wear is serious. Wear through welding repair, frequent replacement, especially the discharge valve, feed valve, exhaust valve wear serious, often stuck, plus pneumatic three large parts damage maintenance costs are high, workers scramble to repair the pump body, high temperature, bad environment, high labor intensity.
2. Complex operation
Because the warehouse pump adopts automatic control of material level and time, the console connection is complicated and there are a few problems, involving electrical, thermal, ash removal overhaul three departments, multiple professionals to the ash field, delay the overhaul time, bring a lot of trouble to the management, difficult to ensure normal production.
3. The environment is bad
Due to the above reasons, in order to ensure the operation, there are many rush repairs, and the equipment leaks ash everywhere, endangering the environment in the factory and the surrounding people's living environment, and causing a great impact on civilized production.
4, affect the comprehensive utilization of fly ash
In order to carry out the comprehensive utilization of fly ash, enterprises have invested heavily in the development of fly ash production lines. However, due to the frequent damage of the conveying system, the normal production of the air separation equipment system cannot be guaranteed, and the ash pipeline cannot be sent out, which affects the user's ash supply and damages the enterprise image and interests.
5, affect the normal operation of sediment pond
Due to the design of ash and slag, bin pump damage, had to water rushed to the sludge pool, resulting in slag water is not enough, water supply tension, and because of the ash fineness is small, easy to cause network blockage, valve, ash pump pipe junction scrap, make the whole slag system loss serious.
6. Although the wear of negative pressure transmission is light, the fan gradually decreases with the air volume after several years of use, resulting in the phenomenon of ash delivery.
Advantages of using powder conveying machine:
1, the equipment investment is small, with a powder conveying machine can replace two bin pump, reduce the equipment investment.
2. The gas pressure of powder conveying machine is 0.04mpa-0.1mpa, which reduces the gas supply pressure, saves gas consumption, and reduces the motor power.
3, reduce the maintenance cost. After the unified installation and commissioning of the system, there is no operation and almost no maintenance. The repairman only needs to check regularly.
4, low pressure transmission, the equipment is better sealed, reliable operation, no plugging phenomenon, the environment is perfect.
