2、Working principle of Vacuum self-priming conveying

Vacuum self-priming conveyingat runtime,Compressed air or other gases are passed through the air supply device to generate airflow, forming a certain airflow speed and pressure. Subsequently, the material is sent into the conveying pipeline through the feeding device, and under the action of the airflow, the material particles are suspended in the airflow or flow along the pipeline in groups. This gas-solid two-phase flow state enables materials to be transported to the target position along the pipeline. In the process of transportation, gas-solid separator (such as dust collector) is used to separate materials from air to ensure the quality of transported materials.，features include Centralized transportation, Flexible layout, Reliable equipment, energy saving and environmental protection and Convenient maintenance，It uses the energy of airflow to transport powder materials along the airflow direction in a closed pipeline.，customizable。

4、Vacuum self-priming conveying structure composition

The Vacuum self-priming conveying structure is introduced as follows:

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. 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. Air source device

The air source device is the power core of the Vacuum self-priming 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. dust pelletizing system

Dust removal system is very important for the environmental protection performance of Vacuum self-priming 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.

5、Vacuum self-priming conveying use

The purpose of Vacuum self-priming conveying is introduced as follows:

1. Process assistance

In some production processes, Vacuum self-priming conveyings are not only used for conveying materials, but also as part of the process. For example, in the chemical and pharmaceutical industries, the Vacuum self-priming 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.

2. Heating, cooling and drying

Heating, cooling or drying equipment can be installed in the Vacuum self-priming conveying pipeline to carry out necessary treatment of materials to meet the specific requirements in the production process.

3. Bulk material transportation

The Vacuum self-priming conveying is especially suitable for conveying powdery, granular and flowable bulk materials. These materials include, but are not limited to, cement, fly ash, grain, plastic particles, pharmaceutical powder, etc. Through the Vacuum self-priming conveying, these materials can be efficiently transferred between different production links or equipment.

4. Environmental protection and cleaner production

The Vacuum self-priming 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.

5. Mixing and classification

In the process of conveying, the Vacuum self-priming conveying system can cooperate with other equipment to realize the mixing and grading operation of materials, and improve the production efficiency and product quality.
