Silver paste filtering device

Abstract

The invention discloses a silver paste filtering device, which comprises a storage bucket, a filter net base plate, a feeding hole, a filter net, an intake and exhaust connection pipe, a vacuum pump and an air compressor, wherein a fixed panel is arranged on the storage bucket; the filter net base plate is arranged on the fixed panel of the storage bucket, and is tightly connected with the fixed panel; the feeding hole is formed above the filter net base plate, and is tightly connected with the filter net base plate; the filter net is arranged in the filter net base plate; the intake and exhaust connection pipe is arranged on the fixed panel of the storage bucket and is communicated with the storage bucket; an extract opening of the vacuum pump is communicated with the intake and exhaust connection pipe through a gas pipeline with a bleeder valve; and a compressed gas outlet of the air compressor is communicated with the intake and exhaust connection pipe through the gas pipeline with an air flush valve. According to the silver paste filtering device, the fineness requirements of silver paste filtering are ensured; and the problem that a plurality of silver sheets blocks the filter net, resulting in low filtering efficiency in the suction filtration process is solved.

Description

technical field [0001] The invention relates to photovoltaic technology, in particular to a silver paste filter device. Background technique [0002] In the photovoltaic industry, the production and use of silver paste is closely related to the fineness of the product. Excessive fineness may lead to poor printing graphics, and even make the screen used for printing scrapped. Therefore, in order to ensure the fineness of the slurry and to filter out some large particles of impurities in the production of the slurry, filtration is essential. [0003] At present, the methods of filtering slurry mainly include: [0004] A. Manual filtering, this filtering method wastes a lot of human resources, low filtering efficiency, and long filtering time. [0005] B. Mechanical paddle filtration. The bearing drives the filter paddle to rotate and extrude the slurry through the filter screen to achieve filtration. This filtering method is easy to break the screen, and it is difficult to c...
