2、Functional advantages of Low vacuum conveying

Low vacuum conveyings have the following advantages.

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

The Low vacuum conveying system can not only realize the transportation of materials, but also carry out various technological operations at the same time, such as mixing, crushing, grading, drying and cooling. This versatility makes Low vacuum conveyings widely used in many industries.

2. High degree of automation

Modern Low vacuum conveying systems are usually equipped with automatic control equipment, such as PLC control system, sensors, actuators, etc., which can realize remote monitoring and automatic adjustment. This highly automated transportation mode reduces labor costs and improves production efficiency and management convenience.

3. Flexible pipeline configuration

The pipeline layout of the Low vacuum conveying is flexible, and it can be configured vertically, horizontally or curved to adapt to the complex production environment and space constraints. This flexibility makes the Low vacuum conveying system have great adaptability in the renovation and expansion of the factory.

4. Generality

The Low vacuum conveying system can transport a variety of materials, including powdery, granular, fibrous and small block materials, and has strong adaptability. At the same time, for materials with unstable chemical properties, inert gas can also be used for transportation to ensure the stability of materials during transportation.

5. Improve conveying efficiency

Can transport materials quickly and in large quantities.

3、Low vacuum conveying application

Low vacuum conveyings have the following purposes.

1. cut down on energy consumption

Although the power consumption of the Low vacuum 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. Dust removal and purification

The Low vacuum 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.

3. Long distance transportation

The Low vacuum 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.

4. material handling

Low vacuum 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.

5. Environmental protection and cleaner production

The Low vacuum 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、Structural advantages of Low vacuum conveying

The Low vacuum conveying has the following structure

1. 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.

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 Low vacuum 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. 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.

6、Introduction of Low vacuum conveying characteristics

Low vacuum conveyingfeatures include Convenient operation and management, Low energy consumption, Reduce material loss, High degree of automation and Avoid material pollution，the product looks beautiful.，It has the functions of cut down on energy consumption, Process assistance, Multi-point transportation, material handling and Heating, cooling and drying，is a kind of high quality and low price Low vacuum conveying，the principle is simple.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.。
