Description

Technical Field

[0001] The utility model relates to the technical field of precious metal recycling equipment, and particularly relates to a dissolution reactor for precious metal waste materials. Background Art

[0002] Precious metal waste materials refer to waste or used items containing precious metals, such as used electronic products, waste circuit boards, used jewelry, used metal catalysts, etc. Precious metals include gold, silver, platinum, palladium, etc., which have important application values in industries and jewelry. In the process of recycling precious metal waste materials, various physical and chemical technologies are usually used.

[0003] The Chinese utility model patent with the authorization announcement number of CN 220485787 U discloses a reactor for recycling precious metal waste materials, which includes: a reactor body and a reactor cover. A limit seat is arranged on the side wall of the reactor body, and a column is slidably arranged inside the limit seat. And a part of the column extends above the limit seat. A first motor is installed at the bottom of the limit seat, and a lead screw is installed at the output end of the first motor. The lead screw penetrates through the limit seat and extends into the column, and the column can slide inside the limit seat through the rotation of the lead screw. The reactor disclosed in this application can allow precious metal waste materials to be washed by acid solutions at different positions in the filter cylinder, avoiding the situation that precious metal waste materials move in the reactor following the flow of the acid solution, accelerating the dissolution speed of precious metal waste materials, improving the recycling efficiency of precious metal waste materials, and also being able to filter and collect the waste residues generated after the dissolution of precious metals through the filter cylinder, avoiding the trouble that the waste residues precipitate at the bottom of the reactor and are inconvenient to clean, which is beneficial to the later treatment work of the waste residues.

[0004] In the above prior art solution, precious metal waste materials are washed by acid solutions at different positions in the filter cylinder. However, during the long-term washing process, larger waste residues will block the mesh holes of the filter screen, resulting in the blockage of the inside and outside of the filter cylinder. Over time, the filtering effect will decline, thus affecting the working efficiency. Therefore, it is urgent to design a dissolution reactor for precious metal waste materials to solve the above problems. Summary of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5, an embodiment provided by the present utility model: a noble metal waste dissolution reactor, comprising: a reaction device 1, the reaction device 1 includes a kettle body 11, and a filtering device 2 is arranged inside the kettle body 11;

[0026] The filtering device 2, the filtering device 2 includes a sieve cylinder 21, a first connecting piece 22 is fixedly connected to the outer surface of the sieve cylinder 21, a second limiting seat 23 is arranged on the inner surface of the sieve cylinder 21, a rotating rod 24 is rotatably connected to the inner surface of the sieve cylinder 21, a second connecting seat 25 is fixedly connected to the outer surface of the rotating rod 24, a fixing ring 26 is fixedly connected to the outer surface of the rotating rod 24, a connecting shaft 27 is fixedly connected to the outer surface of the fixing ring 26, one end of the connecting shaft 27 away from the fixing ring 26 is fixedly connected to a connecting plate 28, a rotating shaft 29 is movably connected to the outer surface of the connecting plate 28, a scraping plate 210 is fixedly connected to the outer surface of the rotating shaft 29, and a rotating tooth 211 is fixedly connected to the outer surface of the rotating rod 24.

[0027] Furthermore, a waste water tank 12 is fixedly connected to the bottom of the outer surface of the reaction device 1, a discharge pipe 13 is fixedly connected to the outer surface of the waste water tank 12, a support seat 14 is fixedly connected to the inner surface of the kettle body 11, and a first limiting seat 15 is fixedly connected to the surface of one end of the support seat 14 away from the waste water tank 12. Through the setting of the waste water tank 12, when the filtered waste water flows into the interior of the waste water tank 12 through the gap between the support seat 14 and the waste water tank 12, the waste water is then discharged through the discharge pipe 13.

[0028] Furthermore, the first connecting piece 22 is movably connected to the upper surface of the support seat 14, and the first connecting piece 22 is movably connected to the upper surface of the first limiting seat 15. Through the setting of the first limiting seat 15, the limiting effect on the sieve cylinder 21 can be effectively realized, thereby ensuring the stability of the device.

[0029] Furthermore, the first connecting piece 22 is fixedly connected to the bottom of the sieve cylinder 21 in three groups, the rotating rod 24 is fixedly connected to the center inside the sieve cylinder 21, and the second limiting seat 23 is arranged on the outer surface of one end of the rotating rod 24 away from the rotating tooth 211. Through the setting of the second limiting seat 23, the limiting effect on the rotating rod 24 can be effectively realized.

[0030] Furthermore, the second connecting seat 25 is movably connected to the inner surface of the second limiting seat 23, the fixing ring 26 is fixedly connected to the outer surface of the rotating rod 24 in three groups, and the connecting shaft 27 is fixedly connected between the fixing ring 26 and the connecting plate 28. Through the setting of the connecting shaft 27, the function of connecting the connecting plate 28 can be effectively achieved, thereby effectively improving the stability of the device. Moreover, since the connecting shaft 27 is connected between the fixing ring 26 and the connecting plate 28, when the connecting plate 28 rotates through the fixing ring 26, a certain bending angle can be generated, avoiding damage to the device due to excessive rigidity of the connection.

[0031] Furthermore, the connecting plate 28 is fixedly connected between the connecting shaft 27 and the rotating shaft 29. The rotating shaft 29 is rotatably connected to the surface of the connecting plate 28 away from the connecting shaft 27. Through the setting of the rotating shaft 29, the angle of the scraper 210 can be adjusted during the rotation of the rotating rod 24, thereby avoiding damage to the device caused by friction between devices.

[0032] Furthermore, the rotating shaft 29 is movably connected between the connecting plate 28 and the scraper 210. The scraper 210 is movably connected to the inner wall of the sieve cylinder 21. Through the setting of the sieve cylinder 21, the surface of the sieve cylinder 21 is hollowed out. When the dissolved wastewater passes through the sieve cylinder 21, the filtered impurities can be effectively left inside the sieve cylinder 21, thus facilitating cleaning.

[0033] Furthermore, the rotating gear 211 is fixedly connected to the surface of the rotating rod 24 away from the second connecting seat 25. Through the setting of the rotating gear 211, the rotating gear 211 is connected to the motor of the reaction kettle. By driving the rotation of the rotating rod 24 through the motor, the filtering device 2 is detachable, thus facilitating the overall cleaning and replacement of the filtering device 2.

[0034] Working principle: When in use, the sieve cylinder 21 is buckled inside the first limiting seat 15 through the first connecting piece 22, thereby playing a role in fixing the sieve cylinder 21. Then, the rotating rod 24 is buckled inside the sieve cylinder 21 through the second connecting seat 25. Subsequently, the waste materials and solutions to be reacted are poured into the sieve cylinder 21 successively. The motor built in the reaction kettle is started, and the rotating gear 211 is driven through the motor to make the rotating rod 24 rotate. Since the rotation of the rotating rod 24 can realize the stirring inside the sieve cylinder 21 and accelerate the chemical reaction at the same time. Due to the particularity of the sieve cylinder 21, as the solution and waste materials are continuously added, the amount of the reaction liquid will continuously increase inside the filtering device 2, and the filtered waste residues will accumulate on the inner wall of the sieve cylinder 21. Then, the inner wall of the sieve cylinder 21 is continuously brushed by the scraper 210, thereby avoiding the accumulation of waste residues affecting filtration. This device is convenient for disassembly and installation, and is more practical and convenient than the traditional waste material dissolution reaction kettle.

Therefore, in any aspect, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description.
