Description

Technical Field

[0001] The utility model relates to the technical field of filtering, in particular to a recyclable sheet-type filter element. Background Art

[0002] As a high-efficiency filtration equipment, the sheet filter element is widely used in industrial production. It is a key component of production equipment such as biaxially oriented polyester film and chemical fiber spinning. In addition, the sheet filter element plays an important role in the fine filtration of high-viscosity polymers. Its superior filtration performance can efficiently filter out hard particles and gel-like pollutants, ensuring the stability of the production process and product quality.

[0003] In order to achieve a good sealing effect, the sheet filter element in the prior art usually welds the filter layer and the edge of the support layer together. However, this design has a significant defect, that is, the filter layer as a consumable cannot be replaced separately, and the user can only replace the entire assembly, resulting in partial waste of the support layer and increased costs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a recyclable sheet-type filter element, in which the filter layer can be replaced separately to realize the recycling of other components.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a recyclable sheet filter element, including a center ring and a filter assembly, the center ring is provided with a plurality of drainage holes, the drainage holes are used to discharge the clean solution after filtration; the filter assembly is in the shape of a disc, the inner ring of the filter assembly is fixedly connected to the center ring, the filter assembly includes an upper filter layer, an upper support layer, a skeleton, a lower support layer and a lower filter layer which are arranged in sequence from top to bottom, and the outer ring edges of the upper filter layer and the lower filter layer are welded to form a disassembly interface.

[0006] Furthermore, the upper support layer, the skeleton and the lower support layer are enclosed in a space formed by the upper filter layer, the disassembly interface, the lower filter layer and the center ring.

[0007] Furthermore, the inner ring of the filter assembly and the center ring are welded or crimped to ensure sealing.

[0008] Furthermore, the material of the filter layer is metal fiber sintered felt.

[0009] Compared with the prior art, the advantage of the utility model is that a disassembly interface formed only by welding the filter layer is provided on the outer ring of the filter assembly. After long-term use, only the filter layer as a consumable needs to be replaced, and the remaining components can be recycled, which greatly reduces material waste and reduces replacement costs.
