2、Closed pipeline transportation principle

Closed pipeline transportationat the start of the operation,Air flow is generated by compressed air or other gases, and a certain air flow speed and pressure are formed in the pipeline. These air currents suspend the material particles in it, or transport the materials along the pipeline in a group state. In this process, the material particles are in a liquid state under the action of airflow, so as to realize the continuous and stable transportation of materials.，It is a product series that integrates Heating, cooling and drying, Dust removal and essence, Reduce pollution, Long-distance and multipoint transportation and Bulk material transportation，mainly based on aerodynamic force, granular materials are transported along the airflow direction in a closed pipeline by using the energy of airflow.，it is mainly composed of Conveying pipeline system, dust pelletizing system, Air source system, control system and delivery system，has been favored by more and more customers.。

3、Structural characteristics of Closed pipeline transportation

The Closed pipeline transportation has the following structure

1. dust pelletizing system

Dust removal system is very important for the environmental protection performance of Closed pipeline transportation 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.

2. 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.

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. Air source device

The air source device is the power core of the Closed pipeline transportation 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. control system

The control system is the "brain" of the Closed pipeline transportation 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、Closed pipeline transportation application

Closed pipeline transportations have the following purposes.

1. Environmental protection and cleaner production

The Closed pipeline transportation 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.

2. Adapt to complex environment

The Closed pipeline transportation 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 Closed pipeline transportation pipes can be flexibly arranged according to the actual situation of the production site, which makes the configuration of factory equipment more reasonable.

3. Dust removal and purification

The Closed pipeline transportation 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.

4. Bulk material transportation

The Closed pipeline transportation 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 Closed pipeline transportation, these materials can be efficiently transferred between different production links or equipment.

5. Mixing and classification

In the process of conveying, the Closed pipeline transportation system can cooperate with other equipment to realize the mixing and grading operation of materials, and improve the production efficiency and product quality.

6、Introduction of Closed pipeline transportation characteristics

Closed pipeline transportationit has the characteristics of Quantitative transportation, High conveying efficiency, Good dustproof effect, Safe and reliable and Reduce material loss，the principle is simple.Air flow is generated by compressed air or other gases, and a certain air flow speed and pressure are formed in the pipeline. These air currents suspend the material particles in it, or transport the materials along the pipeline in a group state. In this process, the material particles are in a liquid state under the action of airflow, so as to realize the continuous and stable transportation of materials.，is an advanced Closed pipeline transportation developed by our company in combination with the actual situation of the industry。

Closed pipeline transportationthe advantage is In the conveying process, various technological operations can be carried out at the same time.、High conveying speed, good conveying quality and high conveying efficiency.、Materials collected from several points can be sent to one place or one place to scattered points.、Materials are transported by closed pipelines.，Less affected by climatic and environmental conditions, fully sealed and pollution-free transportation.、In the process of conveying, various technological operations can be carried out at the same time, such as cool.，in the course of work,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.。
