Description

Technical Field

[0001] The present application relates to the technical field of reaction tanks, and in particular to a palladium waste liquid reaction tank. Background Art

[0002] Palladium is a rare precious metal with a wide range of applications in chemistry, electronics, pharmaceuticals and other fields. Due to its unique physical and chemical properties, palladium plays an important role in industrial production.

[0003] Industrial production processes generate large amounts of waste liquid containing palladium. Direct discharge of this waste liquid not only pollutes the environment but also wastes valuable palladium resources. Therefore, the development of efficient palladium waste liquid treatment technologies is crucial. Palladium waste liquid reactors, key equipment for treating this type of waste liquid, effectively recover palladium from the waste liquid through specific chemical reactions and process conditions, enabling resource reuse.

[0004] For example, the patent with publication number CN221254661U discloses a palladium-containing waste liquid reaction tank. This patent sets a stirring structure in the reaction tank. On the one hand, it can stir the palladium-containing waste liquid and hit the zinc sheets in the palladium-containing waste liquid to separate the palladium on the zinc sheets. On the other hand, it stirs the waste liquid to prevent palladium from forming precipitation at the bottom of the tank body, separates the palladium on the zinc sheets from the zinc sheets, and promotes the continuation of the reaction.

[0005] However, in the actual treatment process of palladium waste liquid, if the reaction conditions are not properly controlled, incomplete reaction may occur. The unreacted raw materials and generated intermediate products may adhere to the inner wall of the tank to form residual waste. These wastes may participate in subsequent reactions as impurities, thereby affecting the purity and quality of the product.

DETAILED DESCRIPTION

[0033] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0035] like Figure 1-Figure 3As shown, the present application provides a palladium waste liquid reaction tank, comprising a bracket 1, and a tank body 2 fixedly arranged at the upper end of the bracket 1, the tank body 2 is used to accommodate the palladium waste liquid to be reacted and the product, and a feed port 3 is fixedly provided on the tank body 2, the feed port 3 is used to introduce the palladium waste liquid to be reacted and the product into the tank, and a discharge pipe 10 is fixedly provided at the bottom end of the tank body 2, and a valve (not marked in the figure) is fixedly provided on the discharge pipe 10, the valve is used to control the discharge of the material in the reaction tank, and when the reaction is completed, the valve is opened to discharge the reaction product from the tank body 2 through the discharge pipe 10;

[0036] A pressure gauge 4 is fixedly provided at the upper end of the tank body 2. The pressure gauge 4 is used to monitor the air pressure changes in the tank body 2 to ensure that the reaction process is carried out within a safe range. At the same time, an exhaust port 5 is fixedly provided at the upper end of the tank body 2 near the pressure gauge 4. The exhaust port 5 is used to discharge the gas generated during the reaction to ensure that the air pressure in the tank body 2 remains balanced.

[0037] At the same time, in order to fully mix the palladium waste liquid in the tank body 2 with other reactants, thereby improving the reaction efficiency and product quality, a stirring mechanism 6 is rotatably provided inside the tank body 2, and the stirring mechanism 6 is used to fully mix the palladium waste liquid with other reactants by stirring;

[0038] The stirring mechanism 6 includes a motor 60 fixedly mounted on the upper end of the tank body 2. The output end of the motor 60 passes through the tank body 2 and is fixedly provided with a stirring shaft 62. At the same time, a shaft seal 61 is fixedly provided at the connection between the output end of the motor 60 and the tank body 2. The shaft seal 61 is suitable for preventing leakage and contamination of miscellaneous bacteria.

[0039] At the same time, multiple sets of stirring paddles 63 are fixedly mounted on the lower end of the stirring shaft 62. The stirring paddles 63 generate shear force and turbulence by rotating to fully mix the palladium waste liquid with other reactants.

[0040] In order to prevent the reactants from adhering to the inner wall of the tank body 2, thereby affecting the sufficient mixing of the palladium waste liquid and other reactants, a fixed rod 64 is fixedly provided on the stirring shaft 62 between the two sets of stirring paddles 63. A scraper 65 is fixedly provided on the fixed rod 64. The scraper 65 is used to scrape off the reactants adhering to the inner wall of the tank body 2 to ensure that the reactants fully participate in the reaction.

[0041] Before the palladium waste liquid reacts, the prepared palladium waste liquid and chemical reagents are first slowly added to the interior of the tank body 2 through the feed port 3. After all the raw materials have been added, the feed port 3 can be closed, and the motor 60 of the stirring mechanism 6 is started to rotate the stirring shaft 62 and the stirring paddle 63. The rotation of the stirring paddle 63 will generate strong shearing force and turbulence, fully mixing the palladium waste liquid and the chemical reagent, thereby fully mixing them so that they can fully react;

[0042] The stirring shaft 62 will drive the scraper 65 to rotate synchronously to scrape off the reactants attached to the inner wall of the tank 2, thereby further allowing the reactants to fully participate in the reaction;

[0043] At the same time, during the reaction process, it is necessary to pay close attention to the changes in the pressure gauge 4. If the pressure exceeds the set value, it means that the pressure inside the tank 2 is too high. At this time, it is necessary to open the valve of the exhaust port 5 to release some gas to reduce the pressure.

[0044] When the reaction is completed, the motor 60 of the stirring mechanism 6 is stopped, so that the stirring shaft 62 and the stirring paddle 63 stop rotating, and the discharge pipe 10 is opened to discharge the material;

[0045] like Figure 2 and Figure 4 As shown, in order to prevent the residual waste from appearing on the inner wall of the tank body 2 after the palladium waste liquid is discharged after the reaction is completed, so that these wastes participate in the subsequent reaction as impurities and affect the purity and quality of the product, a cleaning mechanism 8 is fixedly provided on the upper end of the tank body 2. The cleaning mechanism 8 is used to clean the inner wall of the tank body 2;

[0046] The cleaning mechanism 8 includes a support plate 80 fixedly mounted on the outside of the upper end of the tank body 2, a fixing ring 81 fixedly mounted on the upper end of the support plate 80, a second water pipe 82 fixedly mounted on the upper end of the fixing ring 81, and a water inlet valve 83 fixedly mounted at one end of the second water pipe 82, the water inlet valve 83 being used to control the smooth introduction of cleaning liquid into the second water pipe 82;

[0047] At the same time, a plurality of connecting pipes 84 are fixedly provided on the second water pipe 82. The connecting pipes 84 pass through the tank body 2 and extend into the interior thereof, so as to clean the inner wall of the tank body 2. A first nozzle 85 is fixedly provided on the connecting pipe 84. The first nozzle 85 is obliquely arranged on the connecting pipe 84. When the first nozzle 85 is spraying, the cleaning liquid can be more evenly distributed on the inner wall of the tank body 2, thereby helping to loosen and remove stubborn dirt and residues attached to the inner wall of the tank body 2, thereby improving the cleaning effect.

[0048] A second nozzle 86 is vertically provided at the bottom end of the connecting pipe 84. The second nozzle 86 is used to further clean the residue at the bottom of the tank body 2. When the second nozzle 86 is spraying, the cleaning liquid can penetrate into the gaps and grooves at the bottom of the tank body 2, thereby removing those hard-to-reach dirt and residues.

[0049] When the inner wall of the tank body 2 needs to be cleaned, the cleaning liquid is first transported to the connecting pipe 84 through the second water pipe 82, and then flows to the first nozzle 85 and the second nozzle 86 respectively;

[0050] Finally, two groups of nozzles are used to clean the inner wall of the tank body 2. While cleaning the inner wall of the tank body 2, the motor 60 of the stirring mechanism 6 is started to drive the scraper 65 to clean the waste remaining on the inner wall, so that the inner wall of the tank body 2 can be fully cleaned. After cleaning, the cleaned waste is discharged through the discharge pipe 10.

[0051] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
