[0003] The existing acid leaching device for noble metal-containing material recovery is generally an acid leaching tank, which needs to crush the material during use. The crushed powder is poured into the acid leaching tank for acid leaching, so that the metal substance can be dissolved into the acid leaching tank. However, during dissolution, a large amount of magnetic substances are dissolved in the acid leaching tank, causing the problem of consumption of acid leaching liquid. UTILITY MODEL CONTENT
[0004] Therefore, the utility model provides an acid leaching separating device for noble metal-containing material recovery to solve the technical problem of consumption of acid leaching liquid caused by dissolution of a large amount of magnetic substances in the acid leaching tank.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0027] An acid leaching separation device for recycling precious metal materials, such as Figures 1-5 As shown, the system includes an acid leaching tank 1, inside which is a flotation mechanism 2. The flotation mechanism 2 includes a buoyancy column 201, with a housing 202 fixedly connected to the top of the buoyancy column 201. A first magnetic mesh 203, a second magnetic mesh 204, and a third magnetic mesh 205 are fixedly connected to the inner wall of the housing 202. Telescopic rods 206 are fixedly connected to the corners of the housing 202. A receiving plate 207 is fixedly connected to the movable end of the telescopic rod 206. Liquid inlets 208 are provided on both sides of the receiving plate 207. The linkage structure between the telescopic rod 206 and the receiving plate 207 allows the material to fall to a deeper position with the receiving plate for acid leaching. This not only effectively receives the particles after screening for acid leaching and facilitates their removal, but also ensures uniform penetration of the acid solution through the liquid inlets 208, thereby improving the dissolution efficiency of precious metals.
[0028] See Figure 4 and Figure 5 The bottom of the outer shell 202 is fixedly connected to a guide shell 209. The guide shell 209 has a conical structure. The conical structure reduces the risk of material retention in the guide shell 209, allowing the material to fall accurately and ensuring the continuity of grading and screening.
[0029] See Figure 1 , Figure 2 , Figure 3 and Figure 4The pore sizes of the first magnetic mesh 203, the second magnetic mesh 204, and the third magnetic mesh 205 increase sequentially. This pore size classification reduces the load on a single magnetic mesh, prevents large particles from clogging the fine mesh, such as the first magnetic mesh 203, and extends the service life of the equipment.
[0030] See Figure 4 and Figure 5 There are four telescopic rods 206 arranged in a rectangular shape. The rectangular layout enhances the overall structural stability of the flotation mechanism 2 and can maintain stable contact between the receiving plate 207 and the acid solution when disturbed by the aeration mechanism in the acid leaching tank 1.
[0031] See Figure 4 and Figure 5 The materials of the first magnetic mesh 203, the second magnetic mesh 204 and the third magnetic mesh 205 are all magnetic materials. The magnetic materials and the pore gradient work together to achieve the dual separation of magnetic particles by stepwise adsorption and physical sieving, thereby reducing the interference of non-target metals on the recovery of precious metals.
[0032] See Figure 4 and Figure 5 Handles 3 are fixedly connected around the outer shell 202. The handles 3 are covered with anti-corrosion material. The handles 3 are fixed around the outer shell 202, which facilitates the quick lifting of the flotation mechanism 2 from the acid leaching tank 1, realizing the integrated operation of magnetic particle recovery and equipment maintenance, and reducing downtime.
[0033] The implementation principle of this utility model is as follows: First, after the material is crushed, the powder is put into the outer shell 202 of the flotation mechanism. The powder slides down along the zigzag magnetic mesh. The first magnetic mesh 203 has weak magnetic force and fine mesh, which adsorbs small magnetic particles; the second magnetic mesh 204 has moderate magnetic force and medium mesh, which adsorbs medium particles; the third magnetic mesh 205 has the strongest magnetic force and the largest mesh, which adsorbs large magnetic particles. The unadsorbed particles fall into the receiving plate 207 through the conical guide shell 209, where they come into contact with the acid and dissolve the precious metals. The remaining insoluble impurities sink to the bottom. The aeration mechanism at the bottom of the acid leaching tank continuously generates bubbles, causing the surface of the tank liquid to fluctuate and pushing the flotation mechanism 2 to shake, thereby enhancing the screening efficiency.
[0034] After dissolution is complete, the flotation mechanism 2 is lifted by handle 3 to collect the magnetic material adsorbed on the magnetic net, while the acid leaching residue in the receiving plate 207 is poured out, thus completing the separation.
[0035] Although the embodiments of the utility model have been shown and described, the specific embodiments are only the explanation of the utility model, and are not the limitation of the utility model, and the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable way, and the person skilled in the art can make the modification, replacement and change of the embodiments without the creative contribution after reading the specification without departing from the principles and the purpose of the utility model, but as long as in the claim range of the utility model, it is protected by the patent law.
