As you can see from the live video.，hyde powder it is usually composed of Conveying pipeline system, Bunker system, Conveying pipeline system, control system and Bunker system，This Negative pressure self-priming conveyingThe structural design is simple, novel and special.。

4、Structural characteristics of Negative pressure self-priming conveying

The Negative pressure self-priming conveying has the following structure

1. dust pelletizing system

Dust removal system is very important for the environmental protection performance of Negative pressure self-priming 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.

2. control system

The control system is the "brain" of the Negative pressure self-priming conveying 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.

3. 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.

4. 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.

5. Air source device

The air source device is the power core of the Negative pressure self-priming 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、Working principle of Negative pressure self-priming conveying

Negative pressure self-priming conveyingIt mainly uses the energy of airflow to transport granular materials along the airflow direction in a closed pipeline. It generates air flow with a certain pressure and speed by compressing air or other gases, and suspends materials in the air flow or forms a group to transport along the pipeline.，Widely used incut down on energy consumption,Multi-point transportation,Mixing and classification,Dust removal and essence,Environmental protection and cleaner production and so on，is a technology to transport solid particulate materials through air flow.，it has the characteristics of Reliable equipment, convenient to use, Less maintenance., Fast conveying speed and be of simple construction，it is an ideal choice for customers to buy Negative pressure self-priming conveying。

Negative pressure self-priming conveying

Negative pressure self-priming conveyingthe product looks atmospheric.，in the course of work,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.。
