4、Structural characteristics of Negative pressure suction pneumatic conveying system

The Negative pressure suction pneumatic conveying system structure is introduced as follows:

1. Feeding device

The feeding device is responsible for feeding materials evenly and stably into the conveying pipeline. It is usually installed at the beginning of the system, and uses the negative pressure or positive pressure formed by the air source device to mix materials with air in a certain proportion and send them into the pipeline. Common feeding devices include rotary valves, screw conveyors, rotary feeders, screw pumps, silo pumps and Venturi nozzles. The selection of feeding device should be considered comprehensively according to the characteristics of materials and transportation requirements.

2. Air source device

The air source device is the power core of the Negative pressure suction pneumatic conveying system 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.

3. Conveying pipeline system

The conveying pipeline is a channel for conveying materials after mixing with airflow. It is made of wear-resistant and corrosion-resistant materials to ensure that the materials will not be polluted or damaged during transportation. The diameter, shape and length of the pipeline will be designed according to the characteristics and delivery capacity of the transported materials. In addition, the pipeline system may also include some auxiliary fittings, such as valves, elbows, expansion joints, etc., for regulating air flow and pipeline connection.

4. dust pelletizing system

Dust removal system is very important for the environmental protection performance of Negative pressure suction pneumatic conveying system 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.

5. Bunker system

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.
