Description

Technical Field

[0001] The utility model relates to the technical field of conductive slurry filtering, in particular to conductive slurry filtering equipment with a filter hole anti-clogging structure. Background Art

[0002] With the rapid development of electronic technology, conductive pastes are widely used in many electronic fields. For example, in printed circuit board manufacturing, solar cell electrode preparation, touch screen production and other processes, conductive pastes are used to form conductive lines or electrodes to achieve good electrical connections between electronic components.

[0003] In the prior art, such as publication number: CN217449298U, a filtering device with a multi-layer filtering structure for conductive slurry production is disclosed. It achieves the function of extending the service life of the equipment by installing a No. 1 filter plate and a No. 2 filter plate. The function of the No. 1 filter plate is to filter the conductive slurry once, and the conductive slurry flows out of the filter screen to the No. 2 filter plate for secondary filtration. The No. 1 filter plate is pulled out by a handle, and the slider in the limit groove is moved upward to move the limit block out of the card slot. The No. 2 filter plate is pulled out from the equipment body by the handle for easy cleaning, thereby achieving the function of extending the service life of the equipment.

[0004] In the above patent, although the device can pull out the filter plate for easy cleaning, during the filtration process, solid particles in the slurry are easily accumulated at the filter holes, causing the filter holes to be blocked. As the filtration continues, the blockage phenomenon will become more serious, greatly reducing the filtration efficiency and increasing the filtration time and cost. Moreover, frequent blockages require frequent manual intervention and cleaning, affecting the continuity of the entire production process. For this reason, the utility model provides a conductive slurry filtration device with a filter hole anti-blocking structure. Utility Model Content
