Problems solved by technology
[0003] At present, in the production process of many solar cell modules, the failure of the vacuum pump used with the laminator accounts for a large proportion of defective and scrapped components. When the vacuum pump vacuumizes the components in the laminator, part of the EVA will dissolve in the gas and be removed. Pumped into the cavity of the vacuum pump, and then mixed in the oil, the oil will gradually deteriorate, the sealing and lubrication effect will be reduced, the vacuum degree will be reduced, and the vacuum pump will even be locked, resulting in the scrapping of the laminated components

The invention relates to a vacuum pump filter device for a solar cell laminator, which is arranged between the vacuum pump and the laminator to filter EVA dissolved in the air, including a housing, an air inlet pipe, a filter element, an air outlet pipe and a filter port. The air inlet pipe is arranged on the side of the housing and connected to the solar cell laminator, the air outlet pipe is arranged on the upper part of the housing and connected to the vacuum pump, the filter port is arranged on the lower part of the housing, and the The filter element is arranged inside the casing near the air outlet pipe. Compared with the prior art, the present invention has the advantages of simple structure and remarkable effect.
Description
technical field [0001] The invention relates to a filtering device, in particular to a vacuum pump filtering device for a solar battery laminator. Background technique [0002] The laminator is an important equipment required for the manufacture of solar cell components. It is to press EVA, solar cells, tempered glass, back film (TPT, PET and other materials) into a rigid whole under high temperature and vacuum conditions. kind of equipment. [0003] At present, in the production process of many solar cell modules, the defective and scrapped components caused by the failure of the vacuum pump used with the laminator account for a large proportion. When the vacuum pump vacuumizes the components in the laminator, part of the EVA will be dissolved in the gas and be removed. Pumped into the cavity of the vacuum pump, and then mixed in the oil, the oil will gradually deteriorate, the sealing and lubrication effect will be reduced, the vacuum degree will be reduced, and even the ...
