3、Advantages of Positive and negative pressure mixed conveying principle

Positive and negative pressure mixed conveyingat runtime,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 a comprehensive technology, which involves fluid mechanics, material science, automation technology, manufacturing technology and other fields.，multifunctional, with functions such as Automatic control, Closed conveying, Explosion-proof involves, Environmental protection and pollution-free and material handling，Less maintenance.,Convenient maintenance,Avoid material pollution,High degree of automation,Strong adaptability，has been favored by more and more customers.。

4、Positive and negative pressure mixed conveying structure

The Positive and negative pressure mixed conveying structure is introduced as follows:

1. control system

The control system is the "brain" of the Positive and negative pressure mixed 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.

2. dust pelletizing system

Dust removal system is very important for the environmental protection performance of Positive and negative pressure mixed 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. 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. control system

The control system is the "brain" of the Positive and negative pressure mixed 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.

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.

5、Positive and negative pressure mixed conveying use

The purpose of Positive and negative pressure mixed conveying is introduced as follows:

1. Multi-point transportation

The Positive and negative pressure mixed conveying system can be flexibly configured to realize transportation from multiple centralized points to one centralized point, or from one centralized point to multiple centralized points, so as to meet the complex production layout requirements.

2. Dust removal and purification

The Positive and negative pressure mixed 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. Mixing and classification

In the process of conveying, the Positive and negative pressure mixed conveying system can cooperate with other equipment to realize the mixing and grading operation of materials, and improve the production efficiency and product quality.

4. Heating, cooling and drying

Heating, cooling or drying equipment can be installed in the Positive and negative pressure mixed conveying pipeline to carry out necessary treatment of materials to meet the specific requirements in the production process.

5. Process assistance

In some production processes, Positive and negative pressure mixed conveyings are not only used for conveying materials, but also as part of the process. For example, in the chemical and pharmaceutical industries, the Positive and negative pressure mixed conveying system can cooperate with other equipment to realize process operations such as mixing, grading, drying and cooling of materials, and improve production efficiency and product quality.

6、Positive and negative pressure mixed conveying function

Positive and negative pressure mixed conveyingit has the functions of Physical processing assistance, Closed conveying, material handling, Automatic control and Environmental protection and pollution-free，The materials are completely sealed during transportation.，The material is not affected by the outside world and will not be wet or deteriorated. Not easy to leak, causing dust flying, fully sealed and pollution-free transportation.、In the conveying process, various technological operations can be carried out at the same time.、Intermittent or continuous conveying, multi-point feeding and multi-point discharging, convenient and flexible, wide selection range, and long-distance operation.、High conveying speed, good conveying quality and high conveying efficiency.，meet the needs of material transportation、Materials are transported by closed pipelines.，Less dust flying and spilling, good environmental sanitation conditions, complete sealing and pollution-free transportation.，it is an ideal choice for customers to buy Positive and negative pressure mixed conveying。

Positive and negative pressure mixed conveying

Positive and negative pressure mixed conveyingis a material conveying system that combines jet technology and fluidization technology.，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.。
