2、Structural advantages of Negative pressure suction pneumatic conveying equipment

The Negative pressure suction pneumatic conveying equipment has the following structure

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. control system

The control system is the "brain" of the Negative pressure suction pneumatic conveying equipment 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. dust pelletizing system

Dust removal system is very important for the environmental protection performance of Negative pressure suction pneumatic conveying equipment 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.

5、Negative pressure suction pneumatic conveying equipment use

The purpose of Negative pressure suction pneumatic conveying equipment is introduced as follows:

1. Mixing and classification

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

2. Bulk material transportation

The Negative pressure suction pneumatic conveying equipment is especially suitable for conveying powdery, granular and flowable bulk materials. These materials include, but are not limited to, cement, fly ash, grain, plastic particles, pharmaceutical powder, etc. Through the Negative pressure suction pneumatic conveying equipment, these materials can be efficiently transferred between different production links or equipment.

3. Process assistance

In some production processes, Negative pressure suction pneumatic conveying equipments are not only used for conveying materials, but also as part of the process. For example, in the chemical and pharmaceutical industries, the Negative pressure suction pneumatic conveying equipment 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.

4. Long-distance and multipoint transportation

The Negative pressure suction pneumatic conveying equipment 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 Negative pressure suction pneumatic conveying equipments have important application value in large factories and cross-regional material transportation.

5. save energy and cut emissions

Although the Negative pressure suction pneumatic conveying equipment 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.

6、Advantages of Negative pressure suction pneumatic conveying equipment principle

Negative pressure suction pneumatic conveying equipmentCompressed 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.，the product looks beautiful.，support customization。
