Description

Technical Field

[0001] The utility model belongs to the technical field of sintered felts, in particular to a composite titanium fiber sintered felt. Background Art

[0002] Sintered felt is made from metal fibers with micron-sized diameters, which are laid non-woven, stacked, and then sintered at high temperatures. Multi-layer metal fiber felt, formed by layers of varying pore sizes, creates a pore gradient, enabling controllable filtration accuracy and a greater dirt holding capacity than a single layer of felt. This allows for continuous filtration of the filter cloth, and its three-dimensional, porous structure offers high porosity, a large surface area, and uniform pore size distribution. This overcomes the fragility and low flow rates of powder filtration products, and addresses the heat and pressure resistance of filter paper and filter cloth. Consequently, stainless steel sintered felt exhibits excellent filtration performance, making it an ideal high-temperature, corrosion-resistant, and high-precision filter material.

[0003] However, when the existing sintered felt is used to cover the filter cartridge, the two ends of the sintered felt need to be bonded together. However, most existing methods use an external structure for bonding, which cannot ensure the stability of the two ends of the sintered felt. At the same time, when the sintered felt is used to cover the filter cartridge, it does not have the function of dehydration, so water stains will remain inside the cartridge for a long time, causing the interior to remain damp. To this end, we provide a composite titanium fiber sintered felt to solve the above problems. Utility Model Content

By using splicing pieces one and two, the stability of the titanium fiber sintered felt rolled into a cylindrical structure is ensured. At the same time, the anti-wear layer is located on the surface of the titanium fiber sintered felt, reducing the friction between the titanium fiber sintered felt and the external structure, thereby avoiding damage to the titanium fiber sintered felt.

[0011] The utility model is further configured such that sleeves are fixed at two diagonal positions on the right end face of the anti-wear layer below the titanium metal skeleton mesh, and the sleeves are sleeved at the two end corner positions of the second splicing piece.

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0027] See also Figures 1 to 5 The utility model is a composite titanium fiber sintered felt. By using a splicing piece 105 and a splicing piece 2 108, the stability of the titanium fiber sintered felt rolled into a cylindrical structure is ensured. At the same time, the anti-wear layer 2 is located on the surface of the titanium fiber sintered felt, reducing the friction between the titanium fiber sintered felt and the external structure, thereby avoiding damage to the titanium fiber sintered felt.

[0028] Specifically, the titanium metal skeleton mesh 1; the upper and lower surfaces of the titanium metal skeleton mesh 1 are provided with an anti-wear layer 2, the left end of the titanium metal skeleton mesh 1 is fixed with a splicing piece 105, and the front and rear parts of the lower surface of the splicing piece 105 are fixed with a hanging frame 106, the right end of the titanium metal skeleton mesh 1 is fixed with a splicing piece 2 108, and the front and rear parts of the upper surface of the splicing piece 2 108 are fixed with hooks 109 used in conjunction with the hanging frame 106.

[0029] The operating process of this embodiment is: when the entire titanium fiber sintered felt needs to be covered on the surface side of the filter cartridge, the entire titanium fiber sintered felt is rolled into a cylindrical structure, thereby connecting splicing piece 1 105 and splicing piece 2 108, and making the hook 109 on the end of splicing piece 2 108 directly hang on the hanging frame 106 on the end of splicing piece 1 105, so that splicing piece 1 105 and splicing piece 2 108 are assembled and connected together, thereby ensuring the stability of the titanium fiber sintered felt rolled into a cylindrical structure, and at the same time, the two anti-wear layers 2 are put on the surface position of the entire titanium fiber sintered felt, and then the two anti-wear layers 2 block the surface position of the titanium fiber sintered felt, thereby reducing the friction between the titanium fiber sintered felt and the external structure, and avoiding damage to the titanium fiber sintered felt. Example

[0030] See also Figure 2 On the basis of Example 1, a waterproof layer is covered on the inner side of the titanium metal skeleton mesh 1 rolled into a cylindrical structure to avoid residual water stains.

[0031] Specifically, the upper end surface of the titanium metal skeleton mesh 1 is provided with a filter layer 102, the upper end surface of the filter layer 102 is provided with a titanium fiber felt layer 101, the lower end surface of the titanium metal skeleton mesh 1 is provided with a bonding layer 103, and the lower end surface of the bonding layer 103 is provided with a dehydration layer 104. The titanium metal skeleton mesh 1, the filter layer 102, the titanium fiber felt layer 101, the bonding layer 103 and the dehydration layer 104 are composed by sintering. The titanium metal skeleton mesh 1, the filter layer 102, the titanium fiber felt layer 101, the bonding layer 103 and the dehydration layer 104 are located between the two anti-wear layers 2.

[0032] The operating process of this embodiment is as follows: when the titanium fiber sintered felt is rolled into a cylindrical shape, the adhesive layer 103 and the dehydration layer 104 are located on the inner side of the cylindrical shape. Therefore, after the titanium fiber sintered felt is covered on the filter cylinder, it passes through the dehydration layer 104 to prevent water stains from remaining on its inner side. The adhesive layer 103 ensures that the dehydration layer 104 is installed on the titanium metal skeleton net 1 and is stable. Example

[0033] See also Figure 3 、 Figure 4 and Figure 5 On the basis of Example 1, the sleeve 201 and the positioning strip 202 are used in conjunction with each other to improve the assembly stability of the anti-wear layer 2 and the titanium fiber sintered felt.

[0034] Specifically, sleeves 201 are fixed at the two diagonals of the left end face of the anti-wear layer 2 located above the titanium metal skeleton mesh 1, and the sleeves 201 are sleeved on the two end corners of the splicing piece 105. Sleeves 201 are fixed at the two diagonals of the right end face of the anti-wear layer 2 located below the titanium metal skeleton mesh 1, and the sleeves 201 are sleeved on the two end corners of the splicing piece 2 108. Grooves 107 are provided on the left and right parts of the front and rear side walls of the titanium metal skeleton mesh 1, and the grooves 107 pass through the end faces of the filter layer 102, the titanium fiber felt layer 101, the adhesive coating layer 103 and the dehydration layer 104. A positioning strip 202 located inside the groove 107 is fixed at the position between the two anti-wear layers 2.

[0035] The operation process of this embodiment is: the sleeve 201 is respectively placed on the end corner positions of the corresponding splicing piece 1 105 and the splicing piece 2 108 to ensure that the anti-wear layer 2 can be stably set on the upper and lower surfaces of the titanium fiber sintered felt, and at the same time, the positioning strip 202 is placed in the position of the groove 107, thereby improving the stability of the anti-wear layer 2 and avoiding the position deviation of the anti-wear layer 2.
