Product Description

  1. Characteristics of pneumatic conveying
Simple equipment, compact structure, small footprint, flexible configuration of the conveying pipeline, so that the factory production process is more reasonable.
conveying system is completely closed, less dust flying, can realize the environmental requirements
less moving parts, easy maintenance, easy to achieve centralized control of the entire system and program automation
high efficiency of bulk material conveying, reduce the cost of packaging and handling and transportation
(5) It can avoid moisture, dirt and other sundry materials being conveyed, and ensure the quality of conveyance.
(6) A variety of processes can be realized simultaneously in the conveying process, such as mixing, crushing, grading, drying, cooling, dust removal and other preparatory processes, but also certain chemical reactions
(7) can be concentrated by the number of points of the material transported to a place or from a place to the number of points scattered, and to achieve long-distance operation
(8) for chemically unstable materials, you can use inert gas transportation
2. Classification of pneumatic conveying
There are various ways to categorize pneumatic conveying, and among these, two are commonly used:
1. According to the dense degree of materials in the pipeline, it can be divided into: thin-phase conveying, medium-phase conveying and dense-phase conveying.
Dilute-phase conveying: conveying pressure is relatively low and stable, with the increase of air speed and rise, the material-gas ratio is generally low.
Dense-phase conveying: higher conveying pressure, low gas velocity, can realize high material-gas ratio conveying.
2. According to the airflow formed in the pipeline, it can be divided into three major categories: suction-feeding, pressure-feeding and composite. No matter how many forms of pneumatic conveying devices today, can be categorized into suction-feeding, pressure-feeding type of these two categories
Pneumatic conveying classification
Classification basis Type
Mixing ratio of material and gas Dilute phase <10, Medium phase 10~25, Dense phase >25
Flow mode Suction (negative pressure), pressure (positive pressure)
Gas source pressure (MPa) High vacuum -0.05~-0.02; Low vacuum -0.02~0.02
   
Classification basis Type
Gas source pressure (MPa) Low pressure 0~0.05,; High pressure 0.1~0.7
Conveyor Principle Dynamic pressure (velocity energy), static pressure (pressure energy)
flow state Suspension flow, group flow, bolus flow
Suction pneumatic conveying
The air source equipment is installed at the end of the equipment system. When the fan is running, the whole system forms a negative pressure, at this time, there is a pressure difference in the pipeline, and the air is sucked into the feeding pipe. At the same time, the material is also brought into the pipeline by the air and is transported to the separator. In the separator, the material is separated from the air, the separated material is discharged by the rotary discharge valve at the bottom of the separator, and the air is sent to the dust collector for purification, and the purified air is discharged into the atmosphere through the fan.
 Pressure-fed pneumatic conveying
The air supply unit is located in front of the feed end of the system. Since the fan is located at the front of the system, the material is not free to enter the feed pipe and a sealed pressure feeder unit must be used. When the fan is turned on, the pressure in the pipe is higher than atmospheric pressure. At this point, the material from the hopper enters the pipe via the rotary feed and is then transported by compressed air to the separator. In the separator, the material is separated from the air and discharged by a rotary discharge valve.
Composite pneumatic conveying
It consists of a composite of suction-feeding and pressure-feeding. This system has the characteristics of both, can be from several places to inhale the material, and the material is pressed to a farther place
  1. Flow state of pneumatic conveying
A: Suspension flow conveying
The material conveying speed is higher than the suspension speed, and the material flows in suspension in the pipeline. Concentration ratio is small, this transportation method is suitable for low-pressure dilute-phase short-distance transportation.
B.Group Flow Conveying
The material conveying speed is about equal to the suspension speed, and the material moves into a group state in the pipeline. Concentration ratio is moderate, this transportation method is suitable for medium pressure and long distance transportation.
C:Bolt flow conveying
The material conveying speed is lower than the suspension speed, the material in the pipeline by the pulse valve (air knife) air pressure cut into bolts, relying on the material before and after the bolts of static air pressure difference as the driving force forward. Concentration ratio is high, this conveying method is suitable for medium-pressure and long-distance conveying.
1.Typical application fields
Petrochemical polymers, granules, powder materials, such as transportation, mixing, batching, packaging and other processes
plastics processing enterprises, raw material storage, feeding, weighing, mixing, proportioning and other processes
Metallurgy, electric power enterprises, coal ash, desulfurization ash, dust ash, such as conveying
chemical, biochemical, fine chemical products, such as transportation, mixing, packaging
food, pharmaceutical production of raw materials transportation, mixing, dosing, crushing, drying and other processes
Grain storage, transfer process
Therefore, the design of each pneumatic conveying system needs to analyze the material characteristics, and according to the actual needs of customers and process characteristics to provide suitable overall solutions. The following analysis of the material characteristics of some of the summary, is often considered in the design of pneumatic conveying system
  1. Hazardous Materials   2.Materials of dissimilar composition   
  2. Free-flowing materials  4.Abrasive Materials   5.Wet / Viscous Materials
1. Brittle materials    2. Non-free-flowing materials   3. Easy material material  
4.Fluidized/liquefied materials  5.Large particle size materials
Of course, it is also necessary to understand some of the basic material and chemical properties of the material, as well as the basic requirements for transportation and operation:
 Specific gravity of heap [kg/m3]
Material strength distribution [um-mm
Material temperature [ºC]
Wet content [WT%]
Static electricity accumulation, flammable and explosive explosions, etc.
Conveying capacity, horizontal distance, vertical elevation, number of elbows, etc.

 Working Principle
The inlet of the fan produces a certain negative pressure gas, the material is sucked in from the suction nozzle and transported to the separator, and the material enters the unloader under the effect of gravity, and the material is supplied uniformly under the drive of the motor. The outlet of the fan generates high-pressure gas with a certain pressure, carrying the material to the specified position.
