2、Negative pressure pneumatic conveying performance advantage

The advantages of Negative pressure pneumatic conveying are as follows:

1. Strong flexibility

The conveying pipeline can be flexibly configured according to the factory layout and process requirements, and can meet the conveying requirements regardless of the horizontal, vertical or inclined direction. In addition, the Negative pressure pneumatic conveying system can be seamlessly connected with other production equipment to improve the overall production efficiency.

2. The quality of convey materials is ensure.

In the process of conveying, the Negative pressure pneumatic conveying system can prevent the materials from being wetted, stained or mixed with other sundries, thus ensuring the quality of the conveyed materials.

3. Flexible configuration of conveying pipeline and optimization of process flow.

The Negative pressure pneumatic conveying is carried out in a closed pipeline, which effectively reduces the flying and escape of dust, improves the working environment, reduces environmental pollution, and also protects materials from external pollution.

4. structure

The structure is relatively simple and the operation is very convenient. It can be transported flexibly in horizontal, vertical or inclined directions to adapt to different production environments.

5. Convenient maintenance and easy automation.

The Negative pressure pneumatic conveying system does not need a lot of mechanical equipment, so its maintenance cost is relatively small. In addition, in the process of use, it is only necessary to clean the pipeline regularly and keep it airtight.

3、Working principle of Negative pressure pneumatic conveying

Negative pressure pneumatic conveyingat the start of the operation,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.，features include Easy maintenance, omniseal, Can make full use of space, energy saving and environmental protection and Large conveying capacity，is a comprehensive technology, which involves fluid mechanics, material science, automation technology, manufacturing technology and other fields.，modern technology，low in price。

5、Negative pressure pneumatic conveying application

Negative pressure pneumatic conveyings have the following purposes.

1. Heating, cooling and drying

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

2. Bulk material transportation

The Negative pressure pneumatic 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 Negative pressure pneumatic conveying, these materials can be efficiently transferred between different production links or equipment.

3. Adapt to complex environment

The Negative pressure pneumatic conveying system can adapt to various complex environments and layout requirements. Whether in high temperature, high humidity, corrosive or flammable and explosive environment, the normal operation of the system can be ensured by selecting suitable materials and taking corresponding safety measures. In addition, the Negative pressure pneumatic conveying pipes can be flexibly arranged according to the actual situation of the production site, which makes the configuration of factory equipment more reasonable.

4. Dust removal and purification

The Negative pressure pneumatic conveying system is usually equipped with a dust collector to collect and treat the dust generated in the transportation process to keep the production environment clean and hygienic.

5. Long distance transportation

The Negative pressure pneumatic 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.
