Air cushion conveyor

Abstract

The invention belongs to the field of conveyors, and discloses an air cushion conveyor. The air cushion conveyor comprises a machine body and a conveying rubber belt arranged in the machine body, themachine body comprises a shell and an upper disc groove formed in the shell, a plurality of first air holes are formed in the middle of the upper disc groove, and exhaust holes located below the conveying rubber belt are formed in the two sides of the upper disc groove in the length direction. According to the air cushion conveyor, the exhaust holes are formed in the edge, close to the conveying rubber belt, of the upper disc groove, so that the edge air cushion supporting force of the conveying rubber belt is reduced, the edge of the conveying rubber belt is attached to the upper disc groove,pressurized air below the conveying rubber belt is guided to be exhausted from the exhaust holes, and environmental pollution or environmental protection treatment pressure increase or lifting difficulty increase caused by the fact that the gas enters the position above the conveying rubber belt and is mixed with material dust is avoided.

Description

technical field [0001] The invention relates to the field of conveyors, in particular to an air cushion conveyor. Background technique [0002] At present, in the work of conveying materials by air cushion conveyors, the materials are usually transported by belts (also known as conveyor belts), and when the materials are transported, pressurized air is provided to lift the belts to suspend them and reduce friction. Force and finally realize the belt conveying. In the prior art, after the pressurized air generated by the fan is passed into the air cushion conveyor, the pressurized air enters from the air hole of the upper plate groove into the space between the upper plate groove and the belt to form an air film, which can make the belt be supported. However, after the pressurized air lifts the belt, it will gradually flow to the two ends of the belt along the bottom of the belt, and finally flow out from the edge of the end of the belt and enter into the cavity formed betwe...

AI Technical Summary

Problems solved by technology

In the prior art, after the pressurized air generated by the fan is passed into the air cushion conveyor, the pressurized air enters from the air hole of the upper plate groove into the space between the upper plate groove and the belt to form an air film, which can make the belt be supported. However, after the pressurized air lifts the belt, it will gradually flow to the two ends of the belt along the bottom of the belt, and finally flow out from the edge of the end of the belt and enter into the cavity formed between the material and the cover plate, and enter the increase in the cavity. The compressed air will bring up the dust in the material; if the cavity is sealed, when the cavity is filled with sufficient pressurized air, it will make it difficult for the subsequent pressurized air to hold up the belt, and the return of the pressurized air with dust after shutdown Into the fan; if the cavity is not sealed, there are some gaps for air leakage, etc., the pressurized air with dust will be directly discharged outside the machine, which will cause environmental pollution, and the installation of dust blowing equipment will increase production costs and occupy space

Finally, the air entering the cavity can only be the result of being discharged outside and cannot be recycled, which is not conducive to the reduction of fan energy consumption and the recycling of clean air

[0003] Therefore, the technical problem to be solved in this case is: how to prevent too much pressurized gas from entering the top of the conveyor belt when lifting the conveyor belt, causing environmental pollution or increasing the pressure of environmental protection treatment or increasing the difficulty of lifting
