A blower recovery stretching device

Abstract

The invention provides an air duct recycling and stretching device. The device comprises a steel wire rope (1) suspended on a mineral driver. A negative pressure air duct (2) is arranged on the steel wire rope (1) in a penetrating mode. The air duct recycling and stretching device is characterized in that a supporting rod (3) is arranged, an air duct containing metal frame (4) correspondingly matched with the negative pressure air duct (2) is arranged on the supporting rod (3), an installation screw hole is further formed in a rod body of the supporting rod (3), and one end of the supporting rod (3) is further provided with a roller (6) correspondingly matched with the top wall of the mineral drive. The air duct recycling and stretching device has the advantages that the structure is simple, use is convenient, the device can be directly installed on an existing production device conveniently, the negative pressure air duct can be prevented from being inclined laterally, and the air volume of the air duct is effectively ensured.

Description

Technical field: [0001] The invention provides a storage device, specifically, a blower recovery and stretching device. Background technique: [0002] During the construction of mine roadways, dust control has been paid more and more attention. Dust removal fans have been widely used due to their good dust control and dust removal effects. When the air duct is still hung, the top single-point suspension is adopted. During the operation of the dust removal fan, when the excavator retreats, the negative pressure air duct has a large margin, and the air duct is prone to sideways under the action of suction, resulting in The ventilation section decreases sharply, the air suction volume decreases, the dust removal effect is poor, and even the dust removal fan is damaged. Invention content: [0003] In order to overcome the deficiencies in the prior art, the present invention provides a blower recovery and stretching device which is simple in structure, easy to use, and conveni...
