Tiantian Automation in Dongguan, Guangdong, China is a professional manufacturer of pneumatic conveying systems. It is a high-tech enterprise that integrates scientific research, design, production, sales, and system integration. At present, Dongguan Tiantian Automation Pneumatic Conveying System has been widely used in industries such as new energy, engineering plastics, rubber, food, medicine, chemical industry, building materials, and new materials. Dongguan Tiantian Automation has provided comprehensive material handling solutions for hundreds of domestic and foreign enterprises. The business scope includes a series of products led by pneumatic conveying of materials, storage and arch breaking, metering and batching, weight loss feeding, and automation control systems; Provide customers with a range of comprehensive material handling system solutions.

　　

The pneumatic conveying system mainly consists of equipment and components such as feeders (such as throat pipes, suction nozzles, transmitters, etc.), conveying pipes, air ducts, separators (commonly used are volumetric and cyclone types), air locks (commonly used are flap type and rotary type, which can be used as both feeders and unloaders), dust collectors, and fans (such as centrifugal fans, Roots blowers, water ring vacuum pumps, air compressors, etc.).

　　

The function of the feeder is to feed the material, create a suitable material to gas ratio, and enable the material to start and accelerate. The function of a separator is to separate materials from air and sort them. The function of the air lock is to evenly supply or unload materials while preventing air leakage. The function of a fan is to provide power to the system. High pressure centrifugal fans or water ring vacuum pumps are commonly used in vacuum suction systems; And the compression system requires Roots blower or air compressor.

　　

The materials are completely sealed during the transportation process, with little influence from climate and environment. The working conditions for workers are good, and the materials are not affected by moisture, dirt, or impurities. The equipment is simple, compact in structure, flexible in layout, occupies a small area, and has low equipment costs. It can also perform certain processes (such as powder crushing, drying, and grading) simultaneously, which is easy to control centrally and can achieve automation to improve transportation capacity.

　　

Except for materials that are fragile, highly adhesive, abrasive, corrosive, and prone to chemical changes that require special treatment, generally loose materials can be transported.

　　

After years of research and development in our factory, the pneumatic conveying system has undergone continuous transformation. Due to the equipment's ability to transport various materials such as powders, ultrafine powders, and fine particles, it fully meets the diverse needs of users, especially in recent years when it comes to environmental protection requirements in industrial economic development. The pneumatic conveying equipment fully meets the standards. Through the reasonable construction of the pneumatic conveying material sealing pump pipeline, there is no material leakage during the conveying process of the entire powder material. The application of this device is also

　　

More and more widely used, currently in various industries such as coal powder and fly ash in thermal power plants, granular materials in cement plants, and chemical plants. Fly ash loading machine is a fly ash bulk loader suitable for power, building materials, chemical, grain and other departments, which loads dry powder and granular materials into vehicles and ships. In thermal power plants, it is mainly used for dry dust collectors, ash hoppers or ash storage warehouses, and loading and unloading under slag warehouses. The fly ash loading and conveying system consists of components such as an electric control box, an electric motor, a reducer, a pulley system expansion pipe, a dust collection pipe, and a steel wire rope. Connect them together through steel wire ropes and vacuum tubes to form a stretchable structure. The fly ash loading system is interlocked with the feeding facilities under the material warehouse. After the material truck is filled, it automatically stops loading, achieving automated loading and unloading, high loading efficiency, and low dust pollution. In order to prevent dust generation during ash unloading, a pulse dust removal tank is installed at the fly ash loading system. After entering the dust removal tank, the fly ash undergoes gas ash separation, which is also the end point of pneumatic conveying. The conveying and gasification air is discharged from the top of the tank through a pulse back blowing bag filter and then through a fan. The pulse dust removal tank is designed to operate under negative pressure, and the operation of the exhaust fan at the top of the warehouse plays a role in reducing the pressure inside the warehouse and ensuring the smooth operation of the ash conveying pipeline. The fly ash loading system loads dry powder materials into vehicles and ships. It can be interlocked with the underground feeding equipment to achieve automated control and high loading efficiency. The fly ash outbound loading machine is a new generation of dust-free and mobile negative pressure suction and conveying specialized equipment developed for the outbound loading characteristics of fly ash storage warehouses. The loose fly ash suction machine consists of a suction nozzle, hydraulic suction arm, separation and unloading device, Roots blower, electronic control system, etc. Materials can be directly or mechanically transported into bulk material warehouses. The pneumatic conveying system for bulk materials consists of negative pressure pneumatic conveying equipment, screw conveyor, and electrical control system.

　　

The working principle of pneumatic conveying system is:

　　

The pneumatic conveying system uses a Roots blower to generate negative pressure, mixes the material with a certain amount of air through a suction nozzle, and then passes through a conveying pipe to the separation device. The material is separated from the air and falls down, entering a screw conveyor or directly falling into a tanker truck. The clean air is discharged from the upper part of the separator through the exhaust duct and discharged into the atmosphere through the exhaust port of the Roots blower. The device has a compact structure and reliable operation, making it particularly suitable for the loading and transportation process of fly ash in single story warehouses. The mobility of the device greatly improves work efficiency and economy, reduces work intensity, is fully sealed, and has dust-free performance that is both environmentally friendly and ensures the health of operators, while also ensuring that material properties are not changed.
