3、Structural characteristics of Negative pressure self-priming pneumatic conveying

The Negative pressure self-priming pneumatic conveying has the following structure

1. 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.

2. 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.

3. control system

The control system is the "brain" of the Negative pressure self-priming pneumatic 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. Air source device

The air source device is the power core of the Negative pressure self-priming pneumatic 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.

5. 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.

4、Negative pressure self-priming pneumatic conveying application

Negative pressure self-priming pneumatic conveyings have the following purposes.

1. cut down on energy consumption

Although the power consumption of the Negative pressure self-priming pneumatic conveying is relatively large, the energy consumption can be reduced by optimizing the system design and selecting efficient equipment, so as to achieve the goal of energy saving and consumption reduction.

2. Environmental protection and cleaner production

The Negative pressure self-priming pneumatic conveying process is carried out in a closed pipeline, which effectively prevents dust from flying and leaking, thus reducing environmental pollution and harm to employees' health. This is especially important for industries that need to maintain high cleanliness or dust-free environment.

3. save energy and cut emissions

Although the Negative pressure self-priming pneumatic 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.

4. Multi-point transportation

The Negative pressure self-priming pneumatic conveying system can be flexibly configured to realize transportation from multiple centralized points to one centralized point, or from one centralized point to multiple centralized points, so as to meet the complex production layout requirements.

5. Reduce pollution

The Negative pressure self-priming pneumatic conveying system carries out material transportation in a fully enclosed state, which effectively reduces the environmental pollution caused by dust flying and material leakage.
