Description

Technical Field

[0001] This application relates to the field of palladium-carbon feeding technology, specifically a palladium-carbon feeding device. Background Technology

[0002] Palladium on carbon is a commonly used catalyst widely applied in chemical reactions, particularly in hydrogenation and oxidation. It combines the advantages of palladium metal and activated carbon, exhibiting high activity, high selectivity, and good stability.

[0003] Palladium-on-carbon (PAC) feeding equipment is primarily used in industrial production to uniformly add palladium-on-carbon catalysts into a reaction system. PAC catalysts play a crucial role in many chemical reactions, such as hydrogenation and oxidation. They are widely used in fine chemicals, pharmaceuticals, and environmental protection industries. Several aspects need to be considered when designing and using PAC feeding equipment.

[0004] A search revealed, for example, a patent with publication number CN218057223U, which specifically discloses a feeding device for a palladium-carbon catalyst.

[0005] However, in order to improve the reaction rate of the reactor and ensure the stability of the reaction process, it is usually necessary to manually weigh the palladium catalyst to be added in a quantitative manner to accurately control the amount of feed. This not only increases manpower and material resources, but also makes it easy for errors in manual operation to occur, affecting the overall production efficiency. Therefore, it is necessary to provide a palladium-carbon feeding device to solve the above problems.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] like Figures 1-2 As shown, this application provides a palladium-carbon feeding device, including a reaction tank 1, which is used to mix reactants and palladium-carbon for reaction. In order to facilitate the addition of reactants into the reaction tank 1, an operating platform 11 is provided on the outside of the reaction tank 1. The operating platform 11 has steps 12, so the steps 12 facilitate the operator to climb onto the operating platform 11 to add reactants into the reaction tank 1.

[0034] Meanwhile, the upper end of the operating platform 11 is provided with a feeding mechanism 2, which is used to add reactants into the reaction tank 1. The feeding mechanism 2 has a fixed frame 22 fixedly installed on the operating platform 11. The upper end of the fixed frame 22 is fixedly installed with a discharge box 21, which is used to temporarily store the reactants. The lower end of the discharge box 21 is connected to a screw conveyor 23. The other end of the screw conveyor 23 is provided with a discharge pipe 24, which is connected to the reaction tank 1. In this application, the screw conveyor 23 is the prior art and will not be described in detail here.

[0035] Therefore, when adding reactants to the reaction tank 1, the operator only needs to pour the reactants into the feed box 21, and then the screw conveyor 23 will transport the reactants to the discharge pipe 24 so that the reactants enter the reaction tank 1.

[0036] Furthermore, a feeding mechanism 3 is provided on one side of the upper end of the reaction vessel 1. The feeding mechanism 3 is installed on the operating platform 11 and is used to add palladium carbon catalyst into the reaction vessel 1.

[0037] like Figures 3-5 As shown, a conveying pipe 14 is connected to one side of the upper end of the reaction vessel 1, and a collection bucket 15 is connected to the other end of the conveying pipe 14. The collection bucket 15 has an upward-facing opening, and the feeding mechanism 3 is located on one side of the collection bucket 15.

[0038] The feeding mechanism 3 has a bracket 31 fixedly installed on the upper end of the operating platform 11. A base plate 32 is fixedly installed on the upper surface of the bracket 31. A fixing plate 33 is fixedly installed on the upper side of one side of the base plate 32. A top plate 34 is fixedly installed on the upper end of the fixing plate 33. A hopper 35 is connected to the upper end of the top plate 34 via a pipe. The hopper 35 is used to temporarily store the palladium on carbon catalyst.

[0039] Meanwhile, a groove 37 is provided on the lower end face of the top plate 34, and a metering element 36 is provided on the upper end of the bottom plate 32. The metering element 36 is used to meterly add palladium carbon catalyst into the collection bucket 15. The metering element 36 has a sliding plate 361, which is slidably connected in the groove 37. A feed inlet 362 is provided on the sliding plate 361, which corresponds to the discharge port of the hopper 35. The lower end of the feed inlet 362 is connected to a metering bucket 363, and the bottom of the metering bucket 363 is open.

[0040] Furthermore, a vertical plate 364 is fixedly installed on one side of the measuring container 363, and a cover plate 365 is hinged to the lower end of the vertical plate 364. The cover plate 365 cooperates with the measuring container 363. It can be understood that (specifically as follows) Figure 4 As shown), the cover plate 365 is normally attached to the bottom of the metering tank 363 and is located between the bottom plate 32 and the top plate 34. The slide plate 361 is attached to the bottom of the top plate 34. Therefore, the palladium-carbon catalyst in the hopper 35 will enter the metering tank 363 through the feed inlet 362.

[0041] In order to enable the slide plate 361 to slide automatically, a horizontal plate 38 is fixedly installed on the upper end of the top plate 34 away from the collection bucket 15. A cylinder 366 is fixedly installed on the lower end of the horizontal plate 38. The cylinder 366 has a drive rod 367. The output end of the drive rod 367 is fixedly installed on the slide plate 361. Therefore, starting the cylinder 366 can drive the slide plate 361 to slide in the slide groove 37 through the drive rod 367.

[0042] In this application, the upper end of the operating platform 11 is provided with a storage platform 13, which is used to place the palladium carbon catalyst to be added, thus making it convenient for the operator to add the palladium carbon catalyst into the hopper 35.

[0043] In summary: First, pour the palladium on carbon catalyst into the hopper 35 for later use. If the palladium on carbon catalyst needs to be added in batches, first adjust the metering tank 363 to the upper end of the bottom plate 32, that is, below the hopper 35, wait for the metering tank 363 to be full, and then start the cylinder 366 to push the slide plate 361 towards the collection tank 15 through the drive rod 367.

[0044] At the same time, the metering tank 363 moves towards the collection tank 15. When the metering tank 363 reaches the top of the collection tank 15, the cover plate 365 will be opened by gravity without the obstruction of the bottom plate 32, allowing the material in the metering tank 363 to be discharged and enter the collection tank 15 below, and then be transferred to the reaction tank 1 through the conveying pipe 14.

[0045] As the sliding plate 361 slides, the feed inlet 362 moves away from the hopper 35. Therefore, the sliding plate 361 blocks the discharge port of the hopper 35, preventing it from discharging. When the palladium-carbon catalyst in the metering tank 363 is discharged, the drive cylinder 366 retracts and drives the metering tank 363 to retract and reset. At the same time, the cover plate 365 is blocked by the bottom plate 32 and re-covers the bottom of the metering tank 363 to continue receiving material. Therefore, when adding palladium-carbon catalyst, there is no need for manual quantitative weighing, which reduces manpower and material resources, prevents errors caused by manual operation, and ensures overall production efficiency.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
