2、Positive and negative pressure mixed conveying advantage

The advantages of Positive and negative pressure mixed conveying are as follows:

1. structure

The structure is relatively simple, mainly composed of conveying pipeline, air source equipment, control system, etc., and the maintenance is convenient.

2. Multiple process operations can be carried out at the same time

In the process of conveying, the Positive and negative pressure mixed conveying system can also perform physical operations such as heating, cooling, drying and airflow classification or some chemical operations at the same time, which increases the versatility of the system.

3. Material quality protection

In the process of conveying, the Positive and negative pressure mixed conveying can prevent the materials from getting wet, soiled or mixed with other impurities, thus ensuring the quality of the conveyed materials.

4. Flexible pipeline configuration

The Positive and negative pressure mixed conveying is carried out in a closed pipeline, which effectively prevents dust from flying and escaping. This fully enclosed transportation mode not only improves the working environment, reduces the risk of occupational diseases, but also reduces environmental pollution, and meets the requirements of modern enterprises for environmental protection.

5. High degree of automation

Positive and negative pressure mixed conveyings can realize the automation of transportation process through program control and automation technology. In the whole transportation process, there is no need for manual intervention, and the degree of automation is very high.

4、Working principle of Positive and negative pressure mixed conveying

Positive and negative pressure mixed conveyingat runtime,Using the dynamic pressure and static pressure of air, the material particles are suspended in the airflow or transported in groups along the pipeline. The former is called material suspension transportation, and the latter is called material group transportation.，it is mainly composed of delivery system, Air source system, Bunker system, dust pelletizing system and Air source system，is an advanced Positive and negative pressure mixed conveying developed by our company in combination with the actual situation of the industry。

5、Positive and negative pressure mixed conveying function

Positive and negative pressure mixed conveyingmultifunctional, with functions such as Environmental protection and pollution-free, Closed conveying, Automatic control, Explosion-proof involves and Physical processing assistance，at the start of the operation,Mainly based on aerodynamic force, compressed air or other gases generate airflow, so that material particles are suspended in the airflow or transported in groups along the pipeline. In pressure transportation, high-pressure gas pushes materials to flow along the pipeline; In vacuum transportation, the material is sucked and transported to the target position through the negative pressure environment in the pipeline.。

6、Positive and negative pressure mixed conveying use

The purpose of Positive and negative pressure mixed conveying is introduced as follows:

1. Heating, cooling and drying

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

2. Reduce pollution

The Positive and negative pressure mixed conveying system carries out material transportation in a fully enclosed state, which effectively reduces the environmental pollution caused by dust flying and material leakage.

3. Environmental protection and cleaner production

The Positive and negative pressure mixed 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.

4. save energy and cut emissions

Although the Positive and negative pressure mixed 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.

5. Bulk material transportation

The Positive and negative pressure mixed 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 Positive and negative pressure mixed conveying, these materials can be efficiently transferred between different production links or equipment.

Positive and negative pressure mixed conveying

Positive and negative pressure mixed conveyingWidely used in Process assistance, cut down on energy consumption, Bulk material transportation, Long-distance and multipoint transportation and Dust removal and essence，Flexible pipeline layout, closed pipeline can be adjusted according to production conditions, which is relatively flexible.，meet the needs of material transportation、In the conveying process, various technological operations can be carried out at the same time.、The material is completely closed in the whole conveying process.，It can reduce the pollution to the surrounding environment in the process of transportation, improve the production environment, facilitate safe production, and completely seal and transport without pollution.、Not only can materials be transported from multiple feed points to the discharge point in turn, but also materials can be transported from multiple feed points to the discharge point at the same time.、High conveying speed, good conveying quality and high conveying efficiency.，meet the needs of material transportation。
