Description

Technical Field

[0001] This utility model relates to the technical field of catalyst precious metal impregnation solution collection device, and in particular to a catalyst precious metal impregnation solution collection device. Background Technology

[0002] In the fields of chemical catalysis and materials preparation, catalyst precious metal impregnation solution collection devices are core auxiliary equipment in catalyst preparation processes. They are mainly used to recover the remaining precious metal solution that was not adsorbed by the carrier during the impregnation process, thereby realizing resource recovery and cost control. They are widely used in industrial continuous production scenarios.

[0003] Such devices typically consist of a collection tank, a flow path, a filter assembly, a transfer pump, and a storage tank. The collection tank receives the remaining solution discharged from the impregnation tank or dripping from the carrier; the flow path guides the flow of the solution; the filter assembly removes impurities; the transfer pump is responsible for transferring the solution; and the storage tank is used to temporarily store the recovered solution. The core of this system completes the basic recovery process from receiving the solution to its final storage.

[0004] However, existing devices have obvious drawbacks: the precious metals in the remaining solution have adsorption properties and easily adhere to the inner wall of the impregnation tank, resulting in incomplete recovery and waste of high-value precious metals. To address this, we propose a catalyst precious metal impregnation solution collection device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a catalyst precious metal impregnation solution collection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a catalyst precious metal impregnation solution collection device, comprising a collection pool, four support rods fixedly installed on the top of the collection pool, an mounting plate fixedly connected between the tops of the four support rods, a drive cylinder fixedly installed on the top of the mounting plate, water tanks fixedly sleeved on the outer walls of the four support rods, an impregnation tank fixedly connected between the four water tanks, a solution release component provided inside the impregnation tank, and a precious metal filter plate fixedly installed inside the collection pool.

[0007] Preferably, the top of the mounting plate has two guide rods extending to the bottom of the guide rods that are slidably mounted on both sides of the drive cylinder. A scraper is fixed between the bottoms of the two guide rods. The piston rod of the drive cylinder extends slidably out of the bottom of the mounting plate and is fixed to the top of the scraper. The outer wall of the scraper slides against the inner wall of the impregnation tank.

[0008] Preferably, each of the four water tanks is fixedly connected to a flow pipe at its bottom, and a circular annular water pipe is fixedly connected between the four flow pipes. Four nozzles arranged in a cross shape are fixedly installed on the inner side of the annular water pipe, and the nozzles are installed at an angle of 45 degrees.

[0009] Preferably, a sealing disc is slidably connected inside the impregnation tank, and a circular fixing ring is fixedly provided at the bottom of the sealing disc near the edge. The inner wall of the fixing ring is provided with a ring groove. A main rod is fixedly connected to the bottom of the scraper, and the bottom end of the main rod is fixedly connected to the top of the sealing disc at the corresponding center position.

[0010] Preferably, the solution release assembly includes a release disc, a limiting ring, and a handle. The release disc is rotatably mounted on the bottom of the sealing disc, the limiting ring is fixedly connected to the outer wall of the release disc, the limiting ring is slidably connected in the ring groove, and the top of the release disc slides against the bottom of the sealing disc.

[0011] Preferably, the top of the sealing disc has several sets of holes A extending to the bottom on one side of the main rod, and the top of the release disc has several sets of holes B extending to the bottom on the other side of the main rod. The number of sets of holes A and sets of holes B are equal and symmetrical to each other.

[0012] The beneficial effects of this utility model are: 1. In use, the drive cylinder drives the scraper to slide down the inner wall of the impregnation tank via the main rod. The outer wall of the scraper is in close contact with the tank wall to completely scrape off the attached precious metals. The guide rod provides guidance for the sliding of the scraper, ensuring a smooth and unbiased scraping process. This solves the problem of precious metals being easily adsorbed on the inner wall of the impregnation tank and being incompletely recovered in traditional devices. It removes the high-value precious metals remaining on the tank wall, greatly improves the recycling rate, and reduces production costs.

[0013] 2. In use, this utility model forms a sealed environment by tightly fitting the sealing plate and the release plate, ensuring no leakage during the carrier impregnation process. By rotating the release plate with the handle, hole A and hole B are aligned, enabling the directional and controllable discharge of the remaining solution. This solves the problems of easy leakage and disordered solution discharge leading to the loss of precious metals in traditional devices. The sealed structure ensures that the carrier fully adsorbs precious metals, improving the impregnation effect. The controllable discharge design avoids solution splashing or residue, allowing all remaining solution to flow into the collection tank in a directional manner, reducing initial solution waste.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-5 As shown, a catalyst precious metal impregnation solution collection device is disclosed, comprising a collection tank 1, four support rods 2 fixedly installed on the top of the collection tank 1, an mounting plate 3 fixedly connected between the tops of the four support rods 2, a drive cylinder 4 fixedly installed on the top of the mounting plate 3, water tanks 6 fixedly sleeved on the outer walls of the four support rods 2, an impregnation tank 7 fixedly connected between the four water tanks 6, a solution release component provided inside the impregnation tank 7, and a precious metal filter plate 5 fixedly installed inside the collection tank 1. The collection tank 1 centrally collects all the solution and rinsing mixture to prevent dispersion and loss; the precious metal filter plate 5 can efficiently intercept the precious metal components in the solution, realizing the separation of precious metals and waste liquid.

[0019] The top of the mounting plate 3 is slidably mounted on both sides of the drive cylinder 4, extending to the bottom of the guide rod 12. A scraper 11 is fixed between the bottoms of the two guide rods 12. The piston rod on the drive cylinder 4 slides out of the bottom of the mounting plate 3 and is fixed to the top of the scraper 11. The outer wall of the scraper 11 slides against the inner wall of the impregnation tank 7. The drive cylinder 4 drives the scraper 11 to slide along the inner wall of the impregnation tank 7 through the main rod 13. The scraper 11 fits tightly against the tank wall, which can completely scrape off the attached precious metal residue, solving the problem of incomplete recycling in traditional devices; protecting the tank wall from damage, improving scraping efficiency, greatly improving the recycling rate of precious metals, and reducing production costs.

[0020] Each of the four water tanks 6 has a flow pipe 8 fixedly connected to its bottom. A circular water pipe 9 is fixedly connected between the four flow pipes 8. Four nozzles 10 arranged in a cross shape are fixedly installed on the inner side of the circular water pipe 9. The nozzles 10 are installed at a 45-degree angle. The rinsing liquid in the water tank 6 flows into the circular water pipe 9 through the flow pipe 8. The cross-shaped nozzles 10 can spray evenly to the bottom of the scraper 11 and the dead corners inside the tank, completely removing the scraped precious metal residue and avoiding secondary waste caused by residue adhesion. The rinsing liquid and the remaining solution are recovered simultaneously without generating additional waste liquid, further enhancing the recovery effect and ensuring that no precious metal is leaked.

[0021] A sealing disc 14 is slidably connected inside the impregnation tank 7. A circular fixing ring 16 is fixed at the bottom of the sealing disc 14 near the edge. A ring groove 17 is opened on the inner wall of the fixing ring 16. A main rod 13 is fixedly connected to the bottom of the scraper 11. The bottom end of the main rod 13 is fixedly connected to the top of the sealing disc 14 at the corresponding center position.

[0022] The solution release assembly includes a release disc 18, a limiting ring 20, and a handle 21. The release disc 18 is rotatably mounted on the bottom of the sealing disc 14. The limiting ring 20 is fixed to the outer wall of the release disc 18 and slidably connected in the annular groove 17. The top of the release disc 18 slides against the bottom of the sealing disc 14, and the sealing disc 14 and the release disc 18 fit tightly to form a reliable seal, preventing solution leakage during immersion and ensuring that the carrier fully adsorbs precious metals. By rotating the release disc 18 with the handle 21, the limiting ring 20 smoothly guides the release disc 18 along the annular groove 17, aligning the hole A15 with the hole B19, enabling the controllable and directional discharge of the remaining solution, avoiding solution splashing or residue, and ensuring that all the remaining solution flows into the collection tank 1, reducing initial resource waste. When the release disc 18 rotates to the hole alignment or sealing position, it can be positioned by the damping cooperation between the limiting ring 20 and the annular groove 17 to prevent accidental rotation.

[0023] The top of the sealing disc 14 has several sets of holes A15 that extend to the bottom on one side of the main rod 13, and the top of the release disc 18 has several sets of holes B19 that extend to the bottom on the other side of the main rod 13. The number of the sets of holes A15 and the number of the sets of holes B19 are equal and symmetrical to each other.

[0024] Working principle: During use, the porous carrier is first placed on the sealing plate 14 inside the impregnation tank 7, and then the precious metal impregnation solution is injected into the impregnation tank 7. At this time, the sealing plate 14 and the release plate 18 are tightly fitted to form a sealed structure, which effectively prevents the solution from leaking from the bottom of the impregnation tank 7, ensuring that the carrier fully adsorbs the precious metal in the solution in a closed environment. After the carrier adsorption reaches saturation, the impregnation process is stopped, and the remaining solution is prepared for recovery. Due to the limited adsorption capacity of the carrier, some unadsorbed precious metal solution will remain in the impregnation tank 7. The operator rotates the release plate 18 by the handle 21. The limiting ring 20 on the outer wall of the release plate 18 rotates smoothly along the annular groove 17 of the fixed ring 16 to avoid displacement. When the several sets of holes B19 on the release plate 18 are completely aligned with the several sets of holes A15 on the sealing plate 14, the remaining solution in the impregnation tank 7 flows downward through the aligned holes A15 and holes B19 and falls into the collection pool 1 below to prepare for subsequent filtration. After the remaining solution is discharged, the drive cylinder 4 is started. The piston rod of the drive cylinder 4 extends downward and pushes the sealing plate 14, the release plate 18 and the scraper 11 to slide downward along the inner wall of the impregnation tank 7 synchronously through the main rod 13 connected to the scraper 11. During the sliding process, the outer wall of the scraper 11 is in close contact with the inner wall of the immersion tank 7, thoroughly scraping away the precious metals adhering to the tank wall and avoiding waste due to the adsorption of precious metal residues. At the same time, the guide rod 12 slides synchronously along the mounting plate 3, providing guidance for the downward movement of the scraper 11, ensuring a smooth and unbiased scraping process, and improving the residue cleaning effect. When the scraper 11 slides close to the bottom of the immersion tank 7, the four water tanks 6 are activated. The rinsing liquid in the water tanks 6 is injected into the annular water pipe 9 through the flow pipe 8, and then evenly sprayed onto the bottom of the scraper 11 and the bottom of the immersion tank 7 through the cross-shaped nozzles 10 on the inner side of the annular water pipe 9. The rinsing liquid can not only thoroughly wash away the precious metal residue scraped off by the scraper 11, but also rinse the dead corners at the bottom of the immersion tank 7 to ensure no residue. The mixed solution after rinsing flows into the collection tank 1 together with the previously discharged residual solution. The mixed solution flowing into the collection tank 1 will be filtered through the precious metal filter plate 5 in the tank. The precious metal filter plate 5 can efficiently retain the precious metal components in the solution, realizing the separation of precious metals and waste liquid. The filtered precious metals can be further purified and reused, while the waste liquid can be treated in accordance with environmental protection standards.
