Purging device

Abstract

The invention relates to a purging device. The purging device comprises a main pipeline and a plurality of purging ends. The multiple purging ends are arranged on the main pipeline in the first direction. Each purging end is internally provided with a purging end air guide channel penetrating through the purging end in the second direction perpendicular to the first direction, a purging end firstport communicating with a main pipeline air guide channel, and a purging end second port located at the end, away from the main pipeline, of the purging end. The purging device is constructed to be capable of exhausting air to the outside or exhausting air from the outside through the second port of the purging end, and the radial area, perpendicular to the second direction, of the first port of the purging end is larger than or equal to the radial area, perpendicular to the second direction, of the second port of the purging end. The overall design of the purging device conforms to fluid mechanics, so that gas can be uniformly, controllably and stably sprayed out from the purging ends, the gas sprayed out of the purging ends cannot influence one another, and an air curtain is integrally formed.

Description

technical field [0001] The invention relates to the field of energy, in particular to a purging device for carrying solar cells during the process of processing solar cells. Background technique [0002] With the accelerated consumption of conventional fossil energy such as coal, oil, and natural gas around the world, and the continuous deterioration of the ecological environment, especially the increasingly severe global climate change caused by greenhouse gas emissions, the sustainable development of human society has been seriously threatened. Countries around the world have formulated their own energy development strategies to deal with the limitation of conventional fossil energy resources and the environmental problems brought about by their development and utilization. Solar energy has become one of the most important renewable energy sources due to its reliability, safety, extensiveness, longevity, environmental protection, and resource adequacy, and is expected to b...

AI Technical Summary

Problems solved by technology

These problems include the following aspects: a. The surface of the human body itself will absorb some dust, and the flow of personnel will cause the dust on the surface of the body and the environment to rise, which will reduce the cleanliness of the environment and affect the product yield; b. Manual purging The cell carrier box cannot control the blowing force. When the blowing force is too high, the carrier box will be skewed, which will affect the accuracy of the cells when placed in the carrier box. When the blowing force is too small, the cells will not be cleaned. Carrying box; c. Manually purging the cell cannot control the purge angle. When the purge angle is incorrect, the dust will be suspended in the air for a period of time and then settle down and fall on the surface of the cell; d. The purge uniformity cannot Guarantee, there may be leakage or forgetting of blowing; e, manual blowing will increase manpower and increase labor costs
