AI Technical Summary
The existing inner mesh skeleton structure has low strength and weak compressive strength, resulting in poor filter durability. Furthermore, traditional installation methods cannot guarantee the connection strength between the inner support spring and the inner mesh, which can easily cause deformation of the inner mesh.
The filter mesh structure is made of one piece with spiral reinforcing ribs. The structure is strengthened by spiral reinforcing ribs that extend axially on the filter mesh, and the connection strength is improved by forming spiral reinforcing ribs with rivets and buckles.
It improves the pressure resistance and connection stability of the inner mesh frame, reduces material costs and production processes, and enhances the durability and market competitiveness of the filter.

Description
TECHNICAL FIELD
[0001] The utility model relates to filter technology field, concretely relates to a filter spiral inner net framework. BACKGROUND
[0002] The air compressor oil gas separation filter is composed of metal end cover, metal support framework, sealing glue and filter separation filter material, and its main function is to filter the micro oil drops and solid particles in the oil gas mixture in the air compressor system to meet the clean gas requirement. The metal support framework includes inner net framework and outer net framework, and the existing inner net framework is usually point welding connection or vertical engagement perforated plate net. The inner net of this structure is prone to cause raw material waste during cutting, and the efficiency is low. The structure strength of the inner net framework is low, and the compression resistance is weak, which greatly reduces the durability of the oil gas separation filter and is not suitable for filtering of large pressure medium. In order to solve this problem, some manufacturers install inner support springs in the inner wall of the inner net. The operator needs to insert the inner support spring into the inner net during installation, so that the inner support spring abuts against the inner wall of the inner net. However, this installation method cannot ensure that the inner support spring is flush with the end surface of the inner net, and the inner net is prone to deformation when the inner support spring is inserted, so that the connection strength between the inner net and the inner support spring is poor. SUMMARY
[0003] In order to overcome the defects of the prior art, the purpose of the utility model is to provide a filter spiral inner net framework which has good structure strength, strong compression resistance and can effectively improve the durability of the filter.

[0007] Further preferably, riveting buckles are provided on the blind edges, and the riveting buckles on the two blind edges are riveted and cooperated to form the spiral reinforcing rib.
[0008] More preferably, the edges of the blind edges are bent downward or upward to form the riveting buckles.

[0019] The utility model will be further explained in detail in combination with the drawings and specific embodiments.
[0020] For example, Figure 1 and Figure 2 As shown, the spiral inner mesh skeleton of the filter provided by this utility model includes a cylindrical filter mesh 1. A spiral reinforcing rib 2 is integrally formed on the filter mesh 1, extending spirally along the axial direction of the filter mesh 1. The spiral reinforcing rib 2 protrudes from the surface of the filter mesh 1 and is integrally formed with the filter mesh 1. This not only enhances the structural strength and compressive strength of the inner mesh skeleton, thereby improving the durability of the filter, but also improves production efficiency and significantly saves raw materials. The mesh manufacturing process is reduced, which effectively avoids the problems of easy deformation of the inner mesh or poor connection strength caused by installing internal support springs in the inner mesh in the existing technology. This effectively ensures the quality of the product and helps to enhance the product's market competitiveness and brand influence.
[0021] In some embodiments, specifically, the filter mesh 1 is made of a spirally wound mesh plate. This mesh plate (not shown) has two opposing blind edges (not shown) and a plurality of filter holes 4 located between the two blind edges, and after the mesh plate is spirally wound, the two blind edges cooperate to form spiral reinforcing ribs 2. More specifically, as... Figure 3 As shown, the blind edge is bent downwards or upwards to form a riveting fastener 3. After spiral winding, the riveting fasteners 3 on the two blind edges are riveted together to form a spiral reinforcing rib 2. To ensure the structural strength of the filter mesh 1, the pitch of the spiral reinforcing rib 2 is 50-100mm. A pitch that is too wide will make it difficult to ensure the structural strength of the filter mesh 1, while a pitch that is too narrow will increase the amount of material used. Preferably, the pitch of the spiral reinforcing rib 2 is 95mm. Similarly, to ensure the structural strength of the inner mesh skeleton, the thickness of the mesh plate (i.e., the thickness of the filter mesh 1) is 0.3-0.6mm, preferably 0.4mm. Since the spiral reinforcing rib 2 is formed by riveting the blind edge to form the riveting fastener 3, when the thickness of the filter mesh 1 is 0.4mm, the spiral reinforcing rib 2 is composed of four layers of material, with an overall thickness of 1.6mm. The spiral reinforcing rib 2 at this thickness can effectively increase the compressive strength of the inner mesh skeleton. Preferably, the width of the spiral reinforcing rib 2 is 8-10 mm, which ensures structural strength while saving material. Preferably, the filter hole 4 is a diamond-shaped hole, and the size of the diamond-shaped hole is preferably 7*18 mm; preferably, the number of diamond-shaped holes between two spiral reinforcing ribs 2 in the same vertical direction is preferably 12.
[0022] In actual production, the inner mesh skeleton of the filter can be prepared according to the method: the middle position of the whole strip steel plate with a width of 54 mm is cut open by a device blade, then the cut is opened into a rhombic hole by the transverse tension, the two sides of the rhombic hole are blind edges, the two blind edges are bent and rolled to form riveting buckles 3 by a device, the riveting buckles 3 on the two blind edges are butted and riveted to be pressed tightly, so that the connection is firm and not easy to loosen, then the material is spirally rolled into a cylindrical filter hole net 1 by a special rolling diameter die, the height of the inner mesh skeleton is controlled by a sensor on the device, when the inner mesh skeleton touches the cutting sensor after reaching the preset height, the device starts the cutter to cut off the inner mesh skeleton, and the inner mesh skeleton with a specific height is obtained.
[0023] The above embodiment is only a preferred embodiment of the present application, and cannot be used to limit the scope of protection of the present application. Any non-substantial change and replacement made by a person skilled in the art on the basis of the present application shall fall within the scope of protection of the present application.
