Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical fiber processing, specifically to a multi-layer filter screen frame suitable for chemical fiber processing. Background Technology
[0002] A filter screen, or simply filter mesh, is made of metal wire mesh or textile mesh of different mesh sizes. Its function is to filter molten material flow and increase the flow resistance, thereby filtering out mechanical impurities and improving the mixing or plasticizing effect. When screening material powder during use, special attention should be paid to ensure that the stainless steel wire mesh on the filter element is not deformed or damaged. A multi-layer filter frame can reduce the damage to a single filter screen. Summary of the Invention
[0003] This invention addresses the issue that most existing synthetic fiber filters use a fixed number of filter layers, requiring the entire filter to be replaced during maintenance. Furthermore, many filters are single-layer designs. Based on this, a multi-layer filter frame is designed for equipment requiring multiple layers, facilitating assembly and expansion. By installing individual filter panels on the multi-layer frame, disassembly and replacement are possible, extending the overall service life and reducing maintenance costs.
[0004] This utility model provides a multi-layer filter frame suitable for chemical fiber processing, including: a flow-limiting plate; The supporting sidewalls form a rectangular or circular barrel, with a flow-limiting plate installed on top and a filter screen installed inside; the supporting sidewalls have several rectangular holes for installing L-shaped positioning plates. The vertical surface of the L-shaped positioning plate abuts against the outer surface of the support side wall, and a positioning hole is provided on the horizontal surface. The horizontal surface passes through the rectangular hole of the support side wall and enters the barrel to support the filter screen. The positioning rod passes through the flow restrictor, filter screen, positioning hole, and L-shaped positioning plate and is set parallel to the support side wall, with both ends sealed with bolts; A partition support plate is set between the flow restrictor and the filter screen, and between the filter screens. The side of the partition support plate is provided with ear plates, and the ear plates are provided with positioning holes that go through from top to bottom. The ear plates are fitted onto the positioning rods.
[0005] The flow restrictor and filter screen are existing products and are the current solutions for chemical fiber filtration. The solution provided by this utility model mainly focuses on the filter screen frame structure.
[0006] The partition support plate includes: top edge rod, bottom edge rod, vertical support rod, and X-shaped support rod; the top edge rod, bottom edge rod, vertical support rod, and X-shaped reinforcing rod form a hollow plate body; All the rods of the partition support plate are of the same type; the ear plates are set on the vertical support rods; the width of the top and bottom edge rods is greater than or equal to 1 cm.
[0007] Preferably, when the support sidewalls form a rectangular barrel, the number of layers is determined by the number of filter screens installed, and at least two L-shaped positioning plates are installed on each layer of support sidewalls. At least two partition support plates should be installed, and they should be installed in parallel.
[0008] Preferably, when the support sidewalls are arranged to form a circular barrel, the number of layers is determined by the number of filter screens installed, and each layer of support sidewalls is equipped with at least eight L-shaped positioning plates; the L-shaped positioning plates are connected by virtual lines, and the virtual lines form a grid, and the lines are parallel to the diameter line of the circular barrel. At least two partition support plates should be installed, and they should be installed in parallel.
[0009] As a preferred option, a partition support plate is also installed below the bottom layer of the filter screen.
[0010] The beneficial effects of this utility model are as follows: By selecting different support sidewalls, it can adapt to the filtration needs of different chemical fiber processing. Based on the actual filtration sequence, the number of rectangular holes can be selected, and excess rectangular holes can be closed to match different numbers of layers. The modular design facilitates assembly and disassembly. The positioning rod design serves two purposes: first, to position the filter screen; second, to position the partition support plate. It also provides a fixing function for the bottom partition support plate. The partition support plate supports the filter screen, preventing deformation, especially for easily deformable nylon filter screens. Increasing the number of partition support plates effectively reduces filter screen deformation. Furthermore, the positioning rods between the upper and lower filter screens enhance the overall structural strength. Attached Figure Description

[0012] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. Example 1:
[0013] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a multi-layer filter frame suitable for chemical fiber processing includes: a flow-limiting plate 1; The supporting sidewall 3 has a flow-limiting plate installed on top and a filter screen 5 installed inside; the supporting sidewall has several rectangular holes for installing L-shaped positioning plates 2. The vertical surface of the L-shaped positioning plate abuts against the outer surface of the support side wall, and a positioning hole is provided on the horizontal surface. The horizontal surface passes through the rectangular hole of the support side wall and enters the barrel to support the filter screen. Positioning rod 4 passes through the flow restrictor, filter screen, positioning hole, and L-shaped positioning plate and is set parallel to the support side wall, with both ends sealed with bolts; The partition support plate 6 is set between the flow limiting plate and the filter screen, and between the filter screens. The side of the partition support plate is provided with an ear plate 601, which is provided with a positioning hole that runs through the top and bottom. The ear plate 601 is sleeved on the positioning rod.
[0014] The partition support plate includes: top edge rod, bottom edge rod, vertical support rod and X-shaped support rod; the top edge rod, bottom edge rod, vertical support rod and X-shaped reinforcing rod form a hollow plate, and the connection points are welded.
[0015] All the rods of the partition support plate are of the same type and are made of L-shaped stainless steel strips; the ear plates are set on the vertical support rods; the width of the top and bottom edge rods is 1cm.
[0016] The supporting side walls form a rectangular barrel, with the number of layers determined by the number of filter screens installed. Figure 1 and Figure 2 As shown, there are 3 layers. Each layer has eight L-shaped positioning plates installed on its supporting sidewalls; as... Figure 4 As shown, two partition support plates are provided and arranged in parallel.
[0017] This embodiment does not limit the arrangement of the upper and lower layers of the partition support plate. The upper layer can be parallel to the short side, and the lower layer can be parallel to the long side; alternatively, both layers can be parallel to the long side or both layers can be parallel to the short side. The staggered arrangement of the upper and lower layers does not affect the performance, but only imposes certain requirements on the installation and the materials used. Example 2:
[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the difference between this embodiment and Embodiment 1 is that the supporting sidewalls are formed into a circular barrel.
[0019] Eight L-shaped positioning plates are installed on each layer of support sidewalls; when the L-shaped positioning plates are connected by virtual lines, the virtual lines form a grid, and the lines are parallel to the diameter line of the circular barrel; there are at least two interlayer support plates, which are set in parallel.
[0020] The optimal placement for the tic-tac-toe dotted lines is at two-thirds of the diameter. There are no restrictions on the direction of placement between layers; if the upper layer is set horizontally, the lower layer can also be set vertically. Figure 5 (Based on). Example 3:
[0021] This embodiment is compatible with Embodiments 1 and 2, and only affects the bottom layer filter. In order to reduce the deformation of the bottom layer filter, a partition support plate is also installed below the bottom layer filter.
[0022] The original positioning rod was fixed to the bottom L-shaped positioning plate with bolts at its lower end. However, after adding the partition support plate, the selected positioning rod needs to be extended, and the fixing point is changed to be fixed to the ear plate of the bottom partition support plate.
[0023] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
