Technical Field
[0001] The utility model relates to the technical field of extruder filter accessories, in particular to a backwashing screen changer net hoop for an extruder filter cartridge. Background Art
[0002] A mesh hoop needs to be set on the outside of the filter of the extruder to provide necessary support for the filter during backwashing to prevent the filter from deformation or damage. The mesh hoop of the filter cartridge backwashing screen changer published by the authorization announcement number CN206381724U will be modified on the basis of the traditional mesh hoop to achieve rapid disassembly and assembly of the mesh hoop and improve the efficiency of the ring network. However, there are still some shortcomings in actual application. It is still essentially a large filter net, and the left mesh hoop 1 and the right mesh hoop 2 are two relatively complete pieces. When disassembling and assembling, they need to be pried apart from the middle to both sides. During the prying process, the mesh hoop is prone to deformation, which will affect the next installation and use.
[0003] In view of the above problems, a mesh hoop is proposed, which is light and easy to install and disassemble while ensuring its working performance. It can be broken down into parts, and the replaceability of components is greatly increased, which greatly reduces the maintenance and use costs and improves the efficiency of mesh replacement.

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an extruder filter cartridge backwash screen changer mesh hoop, which effectively solves the problems that the existing extruder mesh hoop is inconvenient to disassemble and assemble during use, the disassembly and assembly process easily causes the mesh hoop to deform, the components are not easily replaceable, and the screen changing efficiency needs to be improved.
[0005] The technical solution is to include an upper ring and a lower ring, the upper ring and the lower ring are symmetrical and coaxially arranged, and a first spiral group and multiple second spiral groups are arranged between the upper ring and the lower ring, wherein the first spiral group is composed of multiple left-handed components, and the multiple left-handed components are evenly distributed around the circumference, and the second spiral group is composed of multiple right-handed components, and the multiple right-handed components are evenly distributed around the circumference; the multiple left-handed components and the multiple right-handed components are coaxial and interwoven into a mesh, the upper ends of the multiple left-handed components and the multiple right-handed components are all placed on the inner side of the upper ring, and the lower ends of the multiple left-handed components and the multiple right-handed components are all placed on the inner side of the lower ring.
[0006] Furthermore, a clearance groove is provided at the intersection of the left-handed component and the right-handed component.
[0007] Furthermore, the ends of the left-handed component and the right-handed component are both provided with notches, the upper ring cooperates with the notch on the upper side, and the lower ring cooperates with the notch on the lower side.
[0008] Furthermore, a plurality of protrusions are provided on the outer edges of the left-handed component and the right-handed component.
[0009] The utility model has an ingenious structure, is light and easy to install and disassemble while ensuring its working performance, and can be divided into parts, thereby greatly increasing the replaceability of components, greatly reducing maintenance and use costs, and improving the efficiency of screen replacement.

[0016] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.
[0017] Depend on Figures 1 to 6 It is given that the utility model includes an upper ring 1 and a lower ring 2, the upper ring 1 and the lower ring 2 are symmetrical and coaxially arranged, and there is a first spiral group and multiple second spiral groups between the upper ring 1 and the lower ring 2, wherein the first spiral group is composed of multiple left-handed components 3, and the multiple left-handed components 3 are evenly distributed around the circumference, and the second spiral group is composed of multiple right-handed components 4, and the multiple right-handed components 4 are evenly distributed around the circumference; the multiple left-handed components 3 and the multiple right-handed components 4 are coaxial and interwoven into a mesh, the upper ends of the multiple left-handed components 3 and the multiple right-handed components 4 are all placed on the inner side of the upper ring 1, and the lower ends of the multiple left-handed components 3 and the multiple right-handed components 4 are all placed on the inner side of the lower ring 2.
[0018] In order to make the network formed by the left-handed component 3 and the right-handed component 4 more stable and prevent unnecessary pressure from occurring at the intersection of the left-handed component 3 and the right-handed component 4, a clearance groove 5 is provided at the intersection of the left-handed component 3 and the right-handed component 4.
[0019] In order to position the upper ring 1 and the lower ring 2 during use and prevent them from slipping, the ends of the left-handed component 3 and the right-handed component 4 are both provided with notches 6, the upper ring 1 cooperates with the notch 6 on the upper side, and the lower ring 2 cooperates with the notch 6 on the lower side.
[0020] A plurality of protrusions are arranged on the outer edges of the left-handed component 3 and the right-handed component 4 .
[0021] It is worth noting that the outer side of the protrusion in the utility model is against the inner wall of the filter cavity on the main body of the screen changer, and its function is to provide sufficient support for the left-handed component 3 and the right-handed component 4, and to ensure that the polymer melt can pass through. The protrusion is fixed to the outer edge of the left-handed component 3 and the right-handed component 4 by fasteners such as pins or screws.
[0022] When using, place the device in Figure 1 The method shown is shown, and then the notches 6 on the ends of the left-handed component 3 and the right-handed component 4 fix the upper ring 1 and the lower ring 2 on the protrusions at both ends of the cylinder of the extruder. When backwashing, multiple left-handed components 3, multiple right-handed components 4, the upper ring 1, and the lower ring 2 make the entire mesh hoop mutually restrain and support each other, which can effectively prevent the filter from deforming. When disassembling, each left-handed component 3 or right-handed component 4 can be disassembled separately, so the disassembly can be completed easily. If some parts are damaged, they can also be quickly replaced with spare parts.
[0023] The utility model has an ingenious structure, is light and easy to install and disassemble while ensuring its working performance, and can be divided into parts, thereby greatly increasing the replaceability of components, greatly reducing maintenance and use costs, and improving the efficiency of screen replacement.
