4、Vacuum dust removal and conveying application

Vacuum dust removal and conveyings have the following purposes.

1. Long-distance and multipoint transportation

The Vacuum dust removal and conveying system can realize long-distance material transportation and meet the demand of long-distance material transfer. At the same time, it can also realize multi-point transportation, that is, materials are collected from multiple locations and transported to a centralized point, or materials are dispersed from a centralized point to multiple locations. This flexibility makes Vacuum dust removal and conveyings have important application value in large factories and cross-regional material transportation.

2. Environmental protection and cleaner production

The Vacuum dust removal and 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、Vacuum dust removal and conveying structure

The Vacuum dust removal and conveying structure is introduced as follows:

1. 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.

2. 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.

3. Air source device

The air source device is the power core of the Vacuum dust removal and 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.

4. dust pelletizing system

Dust removal system is very important for the environmental protection performance of Vacuum dust removal and 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.

5. 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.

Vacuum dust removal and conveying

Vacuum dust removal and conveyingit has the functions of Closed conveying, Explosion-proof involves, Automatic control, Environmental protection and pollution-free and material handling，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.。
