Pneumatic conveying system

Pneumatic conveying, also known as pneumatic conveying, is the conveying method for most powder and granular materials. Generally, it can be divided into positive pressure dilute phase transportation, negative pressure dilute phase transportation and positive pressure dense phase transportation, which can be combined into various forms of material transportation according to the actual demand. No dust, no pollution, flexible layout, efficient transportation, fully meet the measurement, batching, screening, mixing and other processes, equipped with automatic control, not only improve product quality, but also reduce manual intervention, realize automatic production.

  • Positive pressure pneumatic conveying system of bin pump ( sending tank )

lt is mostly used for dense phase high pressure transportation, usually with longer transportation distance andlarger transportation capacity than low pressure transportation.
Technical characteristics:
1 ) lt can be divided into upper - lead bin pump, side-out bin pump and lower - lead bin pump;The transportationforms are various and the selectivity is strong.
2 ) The scaling pressure of the system is high,which is commonly used in inert gas closed-loop circulationconveying system.
3 ) Long service life and low system operation and maintenance cost.

  • Negative pressure pneumatic conveying system

Different from the positive pressure conveying system,the negative pressure system can use asuction nozzle in an open normal temperature container to realize material conveying without raisingthe temperature of the 'material during conveying;
Technical characteristics:
l ) The system has no leakage of dust and gas and no temperature rise in the transported materials,which is especially suitable for hazardous materials.
2 ) The environment around the system is highly clean;

  • Dust collection system

The core equipment of dust collection system is dust collector, also called dust collector.Technical characteristics:
l ) high dust removal efficiency, the efficiency can reach more than 99.9 %, and the dust emission concentration far exceeds thenational standard;
2 ) There are many types of dust collectors, which can be applied to different working conditions in different industries.
A ) according to the form of dust removal, it can be divided into bag dust collctor,sintered plate dust collector, inertial dust colector,electrostatic dust collector, cyclone separator,explosion-proof dust collector,etc.
B ) according to the installation method, it can be divided into: bin top dust collector, independent dust collector, etc.
C ) according to the external features , it can be divided into top - suction dust collector, side - suction dustcollector, cylinder dustcollector, square dust collector,etc.
3 ) According to the characteristics of dust treatment and the requirements of upstream and downstream processes, our company canexclusively customize the optimized dust removal design scheme suitable for customers.

  • Weighing and metering system

Used for single weighing measurement or quantitative batching of multiple materials;

Technical characteristics:
l ) The weighing accuracy is high, the module accuracy can reach 1 %, and the system accuracy can reach l %;

2 ) Weighing forms are various.On the basis of static weighing,it can also meet the dynamic weighingmeasurement under certain conditions.

  • Elutriation separation system

Due to the velocity difference between gas and solid phases in each region, fine dust adhered to the surface ofgranular materials falls off due to the shearing action of gas on the solid surface.
Core equipment: elutriation device and powder remover;It is mainly used for separating fine grains and fiber dustin granular products.
Technical advantages:
l ) Having more than 40 years of research and design experience;
2 ) dust and wire drawing impurities among plastic particles can be efficiently removed;
