Description

Portable combined flexible air duct

Technical Field

The application belongs to the technical field of ventilation equipment, and particularly relates to a portable combined flexible air duct.

Background

The dust hazard is one of five disasters of the mine, a large amount of dust can be generated in the operation process of various mines, the high-concentration dust not only can pollute the operation environment and damage on-site precision equipment, but also can threaten the occupational health of on-site operators, and the underground safety production is greatly threatened. According to the related requirements, the working area must be ventilated and dedusted, that is, clean air is required to be continuously conveyed to the working surface through the air duct so as to ensure the production safety and the working environment of constructors.

In the prior art, the air duct is the most common air guide device, and the basic requirements on the air duct are small air leakage, small wind resistance, light weight and convenient disassembly and assembly. At present, the wind tunnel can be divided into two types of rigidity and flexibility according to the mechanical properties of materials, the rigid wind tunnel is made of metal plates or glass fiber reinforced plastics, and is suitable for various ventilation modes, but the wind tunnel is heavy, has a plurality of joints, is large in size, and is inconvenient to store, carry and install.

The flexible air duct has the greatest advantages of small volume, portability and easy disassembly, and the existing flexible air duct can be divided into a positive pressure air duct, a negative pressure air duct and the like according to an air inlet principle. The positive pressure air duct adopts a cylinder thermal synthesis process, is longitudinally seamless, has the characteristics of flame retardance, static resistance, small wind resistance, low air leakage rate, high strength and the like, and is suitable for being matched with local ventilators with the same size as a tunnel and the like in a coal mine for pressing-in (out) ventilation. The length and the size of the device are required to be customized in advance by a client according to the working condition of the site, and the device is installed in the travelling site. The negative pressure air duct is manufactured by adding carbon spiral spring steel wires into a heat seal cylinder blank and adopting an advanced heat seal process. The device has the characteristics of good suction effect, long service life and the like, is suitable for underground ventilation and dust removal of coal mines, particularly for gas drainage, and can also be used for dust drainage and ventilation of tunnels, chambers and factories.

However, the above two air cylinders have some disadvantages, for example, the stability of the flexible air cylinder is poor, air leakage of the air cylinder is easily caused after the air cylinder is damaged, and the damaged opening is gradually torn and cannot be repaired, so that the air cylinder can only be replaced integrally, the required downtime is long, and the time and the labor are wasted during the later reinstallation.
