Rubber-plastic mining air duct with reflective effect

Abstract

The invention relates to the technical field of exhaust equipment, in particular to a rubber-plastic mining air duct with reflective effect, which includes an air duct cloth, and a plurality of circular rings are sleeved on the air duct cloth, and one side of the circular ring is flexibly connected with multiple A first installation rod, the other side of the ring is movably connected with multiple second installation rods, the end of the first installation rod away from the ring is provided with a mounting groove, and the end of the second installation rod away from the ring is provided with a groove, the installation A moving rod is arranged in the groove, and one end of the moving rod located in the groove is arranged obliquely, a chute is provided on the first installation rod on one side of the installation groove, and a bump is arranged on the moving rod, and the bump extends from the chute . The present invention fixes the air duct cloth through the first installation rod and the second installation rod, so that the operation of the air duct is more stable, and the space is brighter through the reflective film, which is convenient for staff to walk and transport materials, and prevents The staff caused damage to the hair dryer cloth.

Description

technical field [0001] The invention relates to the technical field of exhaust equipment, in particular to a rubber-plastic mining air guide tube with reflective effect. Background technique [0002] The air duct, also known as the ventilation pipe, is a flexible pipe that guides the air flow along a certain direction. At present, there are first-generation rubber-coated air ducts, third-generation plastic-coated air ducts and third-generation vertical and horizontal non-woven ducts in China. Sewing dryer. The air duct is divided into a positive pressure air duct and a negative pressure air duct. The difference between the two is that the positive pressure air cylinder is a 10M section without a skeleton in the middle; while the negative pressure air cylinder is composed of countless steel rings of the air cylinder, also commonly known as the skeleton air cylinder. The air outlet of the positive pressure air duct is to blow air outside, while the air outlet of the negative...

Problems solved by technology

However, the skeleton of the existing negative pressure air duct is not firm, which makes the air guide duct unstable during operation. At the same time, the light in the mine is dim, which has a great impact on the walking of the staff and the transportation of materials.
