2、Structural advantages of Negative pressure conveying

The Negative pressure conveying structure is introduced as follows:

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. 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.

3. 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.

4. 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.

5. control system

The control system is the "brain" of the Negative pressure 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、Negative pressure conveying use

The purpose of Negative pressure conveying is introduced as follows:

1. Adapt to complex environment

The Negative pressure conveying system can adapt to various complex environments and layout requirements. Whether in high temperature, high humidity, corrosive or flammable and explosive environment, the normal operation of the system can be ensured by selecting suitable materials and taking corresponding safety measures. In addition, the Negative pressure conveying pipes can be flexibly arranged according to the actual situation of the production site, which makes the configuration of factory equipment more reasonable.

2. Long distance transportation

The Negative pressure 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.

3. Bulk material transportation

The Negative pressure conveying 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 conveying, these materials can be efficiently transferred between different production links or equipment.

4. material handling

Negative pressure 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. save energy and cut emissions

Although the Negative pressure conveying 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、Negative pressure conveying application

Negative pressure conveyings have the following purposes.

1. Reduce pollution

The Negative pressure conveying system carries out material transportation in a fully enclosed state, which effectively reduces the environmental pollution caused by dust flying and material leakage.

2. Process assistance

In some production processes, Negative pressure conveyings 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 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.

3. Dust removal and purification

The Negative pressure 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.

4. Environmental protection and cleaner production

The Negative pressure 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. Long-distance and multipoint transportation

The Negative pressure 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 Negative pressure conveyings have important application value in large factories and cross-regional material transportation.
