What is a Closed conveying? Introduction to the advantages and characteristics of Pneumatic conveying equipment functions

Closed conveyingis a technical integrated material conveying system that uses air (or gas) flow as conveying power to convey bulk solid materials in pipelines.，is a kind of high quality and low price Closed conveying，multifunctional, with functions such as Closed conveying, Automatic control, Closed conveying, Environmental protection and pollution-free and material handling，It has the functions of Bulk material transportation, material handling, Process assistance, Multi-point transportation and Long-distance and multipoint transportation，it has the functions of Automatic control, Physical processing assistance, Explosion-proof involves, Closed conveying and material handling。The following is to introduce the Closed conveying:

1、Brief introduction of Closed conveying

Closed conveyingmainly uses the airflow generated by the fan to transport materials along the airflow direction in the closed conveying pipeline.，it is widely used in logistics, transportation, grain processing, building materials, build a ship and other industries。

2、Closed conveying principle

Closed conveyingat 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 has the functions of Physical processing assistance, Explosion-proof involves, Automatic control, Environmental protection and pollution-free and material handling，is a Closed conveying，the product looks atmospheric.，usually used in logistics, heat-engine plant, grain processing, cast, chemical plant and other fields。

3、Closed conveying use

The purpose of Closed conveying is introduced as follows:

1. cut down on energy consumption

Although the power consumption of the Closed 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. save energy and cut emissions

Although the Closed 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.

3. material handling

Closed conveying system is widely used in conveying all kinds of powdery, granular and small block materials. These materials include, but are not limited to, cement, fly ash, grain, plastic particles, ore, pulverized coal, pharmaceutical powder, etc. Through the pipeline system, these materials can be efficiently and continuously transported from one place to another, greatly reducing the complexity and cost of manual handling and mechanical transportation.

4. cut down on energy consumption

Although the power consumption of the Closed 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.

5. Dust removal and purification

The Closed 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.

4、Closed conveying structure

The Closed 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. dust pelletizing system

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

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. 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.

5. Air source device

The air source device is the power core of the Closed 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.
