Stable filter screen structure

Abstract

The invention discloses a stable filter screen structure. The stable filter screen structure comprises a filter screen body, the filter screen body is composed of a two-layer structure, i.e. an upper filter screen and a lower filter screen, the upper filter screen and the lower filter screen are connected by support bodies, the filtration pores of the upper filter screen are larger than those of the lower filter screen, the upper filter screen is coated with an anti-affinity layer, the lower filter screen is coated with a wear-resistant metal material, L-shaped support frames are disposed at two ends of the lower filter screen, and the joints of the lower filter screen and the support frames are equipped with shock absorbers. The stable filter screen structure provided by the invention has the beneficial effects that: the structure is simple, a two-layer filtration mode is employed to effectively filter out ink, resin and various adhesives, at the same time the two layers of filter screens are fixed firmly, thus improving work efficiency and reducing the cost, the disposed protective layer can effectively prevent the blockage of the filtration holes and is convenient to clean, the wear-resistant metal material can effectively improve the wear resistant effect, and prolongs the service life, and by setting the support frames and the shock absorbers, the filtering effect can be good, and the stability is improved.

Description

technical field [0001] The invention relates to a filter net, in particular to a stable filter net structure. Background technique [0002] In the process of finishing the paper surface of the paper machine, it is necessary to put the wire mesh on the outside of the mesh cage. The currently used paper machine facing mesh has the following defects: First, the two ends of the ordinary woven rectangular mesh are butted, and then the butt joints are welded In this way, since the peripheral direction of the net sleeve is consistent with the direction of the weft, the deformation is small. When the net sleeve is placed on the inner barrel, it is laborious and difficult to install. In order to facilitate installation, the diameter of the net sleeve is made larger, so that although the installation Easy, but it is easy to loosen during use, resulting in a decrease in the quality of the produced paper and a reduction in the life of the facing net; second, when welding at the interfac...

[0002] In the process of finishing the paper surface of the paper machine, it is necessary to cover the wire mesh on the outside of the cage. The currently used paper machine facing net has the following defects: First, the two ends of the ordinary woven rectangular mesh are butted, and then the butt joints are welded In this way, since the peripheral direction of the net sleeve is consistent with the direction of the weft, the deformation is small. When the net sleeve is placed on the inner barrel, it is laborious and difficult to install. In order to facilitate installation, the diameter of the net sleeve is made larger, so that although the installation Easy, but it is easy to loosen during use, resulting in a decrease in the quality of the produced paper and a reduction in the life of the facing net; second, when welding at the interface, remove the outer warp and keep three-quarters of the end of the weft Left and right, then align the wefts and overlap them, and then weld them. This will cause the size of the mesh at the interface to be different, and the difference from the mesh at other non-butt joints is large. The production of low-grade paper barely meets the requirements. For high-grade paper, it is just can not meet the requirements
