Description

Technical Field

[0001] The utility model belongs to the field of conveyors, and particularly relates to a double-layer drainage structure of an air-cushion conveyor. Background Art

[0002] An air-cushion conveyor is a belt conveyor that supports the conveyor belt and the materials thereon with a thin air film. It replaces the rollers of a roller belt conveyor with perforated air chamber troughs. When the air source supplies air with a certain pressure and flow rate to the air chamber, the air in the air chamber escapes through the small holes on the trough, forming a layer of air film with a certain pressure between the conveyor belt and the trough to support the conveyor belt and the materials thereon. The roller support arranged at a certain interval is changed into a continuous air-cushion support, so that the roller friction between the conveyor belt and the rollers is changed into fluid friction with air as the medium between the conveyor belt and the trough, reducing the running resistance.

[0003] In the prior art, during the working process of the air-cushion conveyor, due to the large temperature difference between day and night and the compressed air, condensate will be generated, resulting in the dampness of the air-cushion conveyor, and it is easy to cause the corrosion of the machine body after a long time. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a double-layer drainage structure of an air-cushion conveyor, which can timely discharge the condensate inside the conveyor, prevent equipment corrosion, and play a role in protecting the conveyor.

The lower trough body is located at the bottom of the machine body. An upper drain pipe is arranged in the lower air chamber, and the upper drain pipe extends laterally out of the machine body. A plurality of water inlet pipes communicating with the upper air chamber are arranged on the upper drain pipe. A lower drain pipe is arranged on the lower side of the machine body, and the lower drain pipe is communicated with the lower air chamber.

[0006] When the utility model works, the conveying wheels at the front and rear ends of the air-cushion conveyor rotate to drive the conveyor belt to convey. The upper conveyor belt is supported on the upper trough body, and the lower conveyor belt is supported on the lower trough body. Compressed air is passed into the air-cushion conveyor through the air inlet.
