[0002] Sintered filter element: It is a new type of filter material made of multi-layer metal sintered mesh, multi-layer stainless steel mesh, which is specially laminated and sintered by vacuum, and has high strength and overall rigidity.
[0003] In the lithium battery industry, sintered mesh filter elements are widely used as key components in the battery production process to filter impurities in lithium slurry to ensure battery performance and safety. Traditional sintered mesh filter elements are made of multiple layers of stainless steel wire mesh that are precisely sintered. The mesh holes are staggered to form a uniform filtering structure that can effectively intercept tiny particles. However, in actual applications, especially when processing high-viscosity lithium slurry under high-temperature environments, the filter element is prone to physical deformation due to the strong suction and the impact force generated by the high-speed flow of lithium materials, resulting in deformation between the filter element mesh holes, which ultimately leads to a decrease in filtration efficiency, affecting product quality and production efficiency. Utility Model Content
[0004] The purpose of the utility model is to overcome the above-mentioned background technical difficulties and provide an internal skeleton type anti-deformation sintered mesh filter element.
[0005] In order to achieve the above purpose, the technical solution adopted is: an internal skeleton type anti-deformation sintered mesh filter element, comprising a filter element, the filter element is a cylindrical shape formed by sintering multiple layers of stainless steel wire mesh, a skeleton is arranged inside the filter element, the skeleton comprises a fixing ring arranged at the bottom of the filter element and having the same diameter as the bottom of the filter element, a plurality of connecting rods are vertically arranged upward on the surface of the fixing ring, and the ends of the plurality of connecting rods are fixed with reinforcing rings tangent to the inner wall of the filter element;
[0006] The surfaces of the fixing ring, the connecting rod and the reinforcing ring are all fixed with a ring body, the left and right ends of the ring body are provided with a strap mounted on the inner wall of the filter element, the strap is provided with a plurality of positioning grooves on the surface close to the inner wall of the filter element, the outer wall of the filter element is provided with a buckle at the corresponding position of the strap, the surface of the buckle is provided with a socket corresponding to the position of the positioning groove, and a threaded member is provided between the socket and the positioning groove for locking.
[0007] Furthermore, an annular groove is provided on the outer wall of the positioning groove of the strap, the annular groove is spaced 0.1-0.2 mm from the positioning groove, and an annular tube inserted into the inner wall of the annular groove is provided on the side of the buckle close to the strap.
[0008] Furthermore, each of the straps is evenly arranged at the upper, middle and lower sections of the positioning groove strap.
[0009] Furthermore, the inner wall of the fixing ring is provided with X-shaped support strips which are arranged crosswise and parallel to the inner bottom surface of the filter element.
[0010] Furthermore, the fixing ring, connecting rod, supporting bar and reinforcing ring are all made of high-strength, corrosion-resistant stainless steel, and the connecting surfaces of the fixing ring, connecting rod, supporting bar and reinforcing ring are made by precision welding or bonding.
[0011] Furthermore, the threaded member is a countersunk screw.

In actual use, if the filter element and the skeleton are bonded and set, the filter element is soaked in lithium battery materials for a long time, which is easy to cause the bonding material to fall off. If the filter element and the skeleton are welded, the labor cost will be greatly increased. At the same time, if there is a problem with the skeleton or the filter element after welding, the stability of the entire filter element will be affected, and both of them must be replaced together, and the replacement cost is higher. The fixed ring, the connecting rod and the reinforcing ring surface are all fixedly provided with a ring body, and the flaps set on the left and right ends of the ring body and the buckle on the outer wall of the filter element can be connected through a threaded part.

Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0022] Embodiment 1

[0024] like Figure 3-4 A ring body 7 is fixedly provided on the surfaces of the fixing ring 4, the connecting rod 3 and the reinforcing ring 5. The left and right ends of the ring body 7 are provided with a strap 6 mounted on the inner wall of the filter element 1. The strap 6 is provided with a plurality of positioning grooves 9 on the surface close to the inner wall of the filter element 1. A buckle 8 is provided on the outer wall of the filter element 1 at the corresponding position of the strap 6. A plug hole 10 corresponding to the position of the positioning groove 9 is provided on the surface of the buckle 8. A threaded member is provided between the plug hole 10 and the positioning groove 9 to lock it. In specific implementation, the threaded member is a countersunk screw.
[0025] In specific implementation, each strap 6 is evenly opened in the upper, middle and lower sections of the positioning groove 9, such as Figure 1 As shown, the inner wall of the fixing ring 4 is provided with X-shaped support strips which are parallel to the inner bottom surface of the filter element 1 and cross-arranged.
[0026] In specific implementation, the fixing ring 4, the connecting rod 3, the support bar and the reinforcing ring 5 are all made of high-strength, corrosion-resistant stainless steel, and the connecting surfaces of the fixing ring 4, the connecting rod 3, the support bar and the reinforcing ring 5 are made by precision welding or bonding.
[0027] The specific implementation method is as follows: When using this internal skeleton 2 type anti-deformation sintered mesh filter element 1, the skeleton 2 is first placed in the filter element 1 tube. The setting of the skeleton 2 fixing ring 4, connecting rod 3 and reinforcement ring 5 is precisely matched with the internal contour of the sintered mesh. After application, it can provide balanced support force in all directions of the inner wall of the filter element 1, ensuring that the filter element 1 will not undergo physical deformation when subjected to strong suction and the impact force generated by the high-speed flow of lithium material, avoiding mesh deformation, ensuring the filtration efficiency of the filter element 1, thereby ensuring the quality of the products produced and the production efficiency.
[0028] At the same time, a ring body 7 is fixedly provided on the surface of the fixing ring 4, the connecting rod 3 and the reinforcing ring 5.

An annular tube 12 inserted into the inner wall of the annular groove 11 is provided on the side of the buckle 8 close to the strap 6. After this setting, when the buckle 8 is connected with the buckle ring, the annular tube 12 on the buckle 8 is inserted into the annular groove 11. The entire buckle ring and the buckle 8 can no longer move up, down, left, or right. Then the screw is tightened in the positioning groove 9, and the connection relationship is tighter. The stability of the skeleton 2 and the filter element 1 is better. This setting can be used when the aperture of the sintered mesh filter element is large. In specific implementation, it can be considered to set the annular groove 11 and the positioning groove 9 as positioning holes and positioning rods. This setting can cope with sintered mesh filter elements with smaller apertures.
[0031] Embodiment 3
[0032] On the basis of Example 1 and Example 2, when the filter element 1 is implemented, most of the time the diameter of the filter element 1 does not need to be changed, but the height of the filter element 1 changes. Therefore, the height of the skeleton 2 inside the filter element 1 becomes a big problem. In this regard, the applicant sets the connecting rod 3 in the skeleton 2 to a retractable setting. After this setting, the whole skeleton 2 has better adaptability and stronger usability.
