The principle of powder pneumatic conveying
When facing dust transportation, dust pollution may occur, which not only harms the health of operators, but also pollutes the production environment. Some materials may have the risk of flammability, which may lead to the possibility of dust explosions during transportation. Moreover, due to the country's attention to environmental pollution, many enterprises have stopped production due to non-compliance with emission standards. If pneumatic conveying of dust is used, all the above problems can be solved, which not only reduces production costs but also increases production efficiency, makes the workshop clean, and wins more customers. So what factors need to be considered in the design of pneumatic conveying systems? Let's explain below.
Pneumatic conveying systemIt is a comprehensive technology that involves aspects such as fluid mechanics, materials science, automation technology, manufacturing technology, and so on. It is a high-tech project with high transportation efficiency, minimal land occupation, and no economic pollution. Powder conveying and gravity conveying are important methods for conveying powder (or particles smaller than 10mm). Pneumatic conveying system, also known as gas conveying, powder conveying, dense phase conveying, etc., is the force of air flow and transports materials along the air flow in a closed pipeline. The organization of power transportation is very simple. It can be horizontal, straight, or inclined. During transportation, the materials in the pipeline can be heated, cooled, and dried. Widely used in workshop ash removal preparation, preparation of water conservancy and hydropower construction sites and concrete mixing plants, homogenization and dumping of cement, transportation of various powdered materials, transportation and transfer of powdered materials in metallurgy, chemical and other industries, repair materials, storage yards and other industries. Pneumatic conveying system is a new type of conveyor developed in recent years. The pneumatic conveyor must have dedicated time to debug the equipment and load it onto the PLC control platform. In fact, the working principle of pneumatic conveyors can be metaphorically described in our own words.
The following is the positive pressure pneumatic conveying structure diagram of the powder pneumatic system, as shown in Figure 1:

You can put some things in one place and in many different places at the same time. This equipment can be used in different powder cleaning pneumatic conveying equipment, and pneumatic conveying equipment is also used in our daily lives in this project. The powder pneumatic conveyor does not have excessive angular design, so it is very convenient and convenient to clean powder. The volume of the powder pneumatic conveyor is very small, so moving the powder pneumatic conveyor is very convenient. Pneumatic conveying of powder is very simple and convenient in the process of pneumatic conveying. When the powder pneumatic conveyor is working, the sound is very low, even ignored, almost non-existent. Powder pneumatic conveyor is very safe, and it does not generate heat during engineering operation, so there will be no uniform ignition phenomenon; Pneumatic powder conveyor does not generate static electricity during operation. Widely used in industries such as chemical, food, pharmaceutical, and feed.
We can design products that meet the actual production needs of customers based on their site conditions and material characteristics, and provide a one-stop service from scheme design, production development, sales to sales, installation and commissioning to technical training and maintenance. After the mixture of material and gas, it is transported through a pipeline at a certain flow rate to the material and gas separation equipment at the end point. The separated material enters the silo and the gas is discharged into the atmosphere. System features: low flow rate, minimal wear on pipelines; Low gas consumption, suitable for long-distance transportation; Single tank transportation is intermittent transportation, and to achieve continuous transportation, double tanks need to be used; Less breakage and low noise; High degree of automation; Positive pressure dilute phase pneumatic conveying system is a conveying method in which the pressure of the entire pipeline system is greater than the local pressure. Generally, a Roots blower is used as the air source to introduce positive pressure air higher than the local atmospheric pressure into the feeding system. The material enters the feeder for quantitative feeding through the hopper and suction chamber under the action of gravity. After mixing the material with gas, maintain a certain flow rate in the pipeline and transport it to the material and gas separation equipment at the end through the pipeline. The separated material enters the silo, and the air is separated and filtered before being discharged into the atmosphere. Features: Low conveying energy consumption (low negative pressure, less dilute phase), multi-point unloading, easy automation, multi-point feeding (multiple feeding points).
