3、Positive and negative pressure combined conveying application

Positive and negative pressure combined conveyings have the following purposes.

1. Long distance transportation

The Positive and negative pressure combined 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.

2. save energy and cut emissions

Although the Positive and negative pressure combined 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.

3. material handling

Positive and negative pressure combined 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.

4. Long-distance and multipoint transportation

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

5. Reduce pollution

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

4、Positive and negative pressure combined conveying structure composition

The Positive and negative pressure combined conveying has the following structure

1. dust pelletizing system

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

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. Air source device

The air source device is the power core of the Positive and negative pressure combined 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. 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、How much is the Positive and negative pressure combined conveying?

The Positive and negative pressure combined conveying price is introduced as follows:

1. company strength

Our company's expected profit value of Positive and negative pressure combined conveying is relatively low, and adopts the sales policy of small profits but quick turnover, so the price positioning of Positive and negative pressure combined conveying is relatively low.

2. technology content

High-tech products need more advanced technology to support them, so products with higher performance will also lead to a general increase in their prices, and vice versa.

3. product model

There are various specifications and models of Positive and negative pressure combined conveying, and the performance of different specifications and models is quite different. Customers should choose products with appropriate specifications and models according to the actual situation.

4. deploy

Usually, the quotation of Positive and negative pressure combined conveying changes with its configuration, but the quotation is different according to the different needs of customers and different product configurations.

5. Manufacturer's sales model

There are direct selling manufacturers and agents in the market. Agents are higher than direct selling manufacturers, mainly because agents get goods from manufacturers, sell them to customers and earn the difference from middlemen, so the natural price is higher.
