3、Structural advantages of Negative pressure vacuum conveying

The Negative pressure vacuum conveying has the following structure

  1. Bunker system
  2. The silo temporarily stores and releases materials. The silo is usually designed as a pyramid or conical structure to facilitate the storage and unloading of materials. The design of silo needs to consider the different problems of materials in the process of storage and unloading and the flow form of materials.

  3. dust pelletizing system
  4. Dust removal system is very important for the environmental protection performance of Negative pressure vacuum conveying system. It is responsible for handling the dust and waste gas generated in the transportation process to ensure that the discharge meets the requirements of environmental protection. Dust removal system usually includes dust collector, fan and discharge pipeline. According to different material characteristics and environmental protection requirements, different dust removal equipment and technical schemes can be selected.

Dust removal system usually includes dust collector, fan and discharge pipeline. According to different material characteristics and environmental protection requirements, different dust removal equipment and technical schemes can be selected.

  7. Air source device
  8. The air source device is the power core of the Negative pressure vacuum conveying system, which provides the airflow power needed for transportation. Common air source equipment includes roots blower, compressor, centrifugal blower and water ring vacuum pump. These devices can generate stable airflow and provide sufficient power for the transportation of materials.

  9. control system
  10. The control system is the "brain" of the Negative pressure vacuum conveying system, which is responsible for monitoring and controlling the whole system. Through the control equipment such as programmable controller, the parameters such as airflow speed, feed rate and system pressure can be accurately adjusted and controlled to ensure the stable operation of the system and meet the production requirements.

4、Negative pressure vacuum conveying application

Negative pressure vacuum conveyings have the following purposes.

  1. save energy and cut emissions
  2. Although the Negative pressure vacuum conveying system itself needs to consume some energy, compared with other transportation modes, it usually has higher transportation efficiency and lower maintenance cost. In addition, by optimizing the system design and adopting advanced energy-saving technology, energy consumption can be further reduced and the goal of energy saving and emission reduction can be achieved.

  3. Heating, cooling and drying
  4. Heating, cooling or drying equipment can be installed in the Negative pressure vacuum conveying pipeline to carry out necessary treatment of materials to meet the specific requirements in the production process.

  5. Process assistance
  6. In some production processes, Negative pressure vacuum conveyings are not only used for conveying materials, but also as part of the process. For example, in the chemical and pharmaceutical industries, the Negative pressure vacuum conveying system can cooperate with other equipment to realize process operations such as mixing, grading, drying and cooling of materials, and improve production efficiency and product quality.

  7. Long distance transportation
  8. The Negative pressure vacuum conveying system can realize long-distance material transportation and meet the demand of long-distance material transfer. This is especially important for some large factories or cross-regional material transportation.

  9. Mixing and classification
  10. In the process of conveying, the Negative pressure vacuum conveying system can cooperate with other equipment to realize the mixing and grading operation of materials, and improve the production efficiency and product quality.
