Technical Field
[0001] This utility model relates to the field of catalyst preparation technology, and more specifically to a feeding mechanism and a reaction device for preparing precious metal catalysts. Background Technology
[0002] Precious metals mainly refer to eight metallic elements: gold (Au), silver (Ag), and the platinum group metals (ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os), iridium (Ir), and platinum (Pt). They have wide applications in industry. For example, platinum and palladium are used as catalysts in automotive exhaust purification systems to help reduce harmful gas emissions. Gold and silver are used in connectors and contacts in electronic products due to their excellent conductivity and corrosion resistance. Precious metal catalysts are catalysts with precious metals as the active component. They utilize the unique electronic structure and surface properties of precious metals to accelerate chemical reaction rates, while the catalysts themselves do not undergo permanent chemical changes before and after the reaction. The molding and granulation equipment used to manufacture precious metal catalyst supports requires the use of conveyor belts and other similar equipment.
[0003] For example, in the prior art disclosure CN222267060U, a feeding mechanism and a reaction device for preparing precious metal catalysts are disclosed. This utility model uses an inclined baffle and a pressure roller to adjust the material occupancy area, which facilitates the material entering the feed hopper. The feed hopper can also adjust its own opening size with the baffle, which can effectively reduce the accumulation of material.
[0004] However, the existing technology described above still has the following problems in use: some precious metal catalyst raw materials may cause blockage due to agglomeration; at the same time, the raw materials are prone to agglomeration when in contact with humid air, which will reduce the feeding efficiency and affect the subsequent granulation effect. Based on this, the present invention provides a feeding mechanism with filtration and drying functions and a precious metal catalyst preparation reaction device. Utility Model Content
[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a feeding mechanism and a reaction apparatus for preparing precious metal catalysts. The precious metal catalyst raw material is guided to fall evenly onto the conveyor belt through a feeding hopper. At the same time, the vibrating feeding hopper and filter plate can disperse the lumpy raw material, which can not only improve the filtration efficiency but also facilitate subsequent preparation. Furthermore, the hot air blown out by multiple air outlets can dry the raw material, preventing the precious metal catalyst from becoming damp and clumping, thus avoiding its impact on subsequent production. This solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism, comprising a housing and a conveyor belt disposed inside the housing, a cover plate on the top of the housing, a feed hopper penetrating one side of the top of the cover plate, a filter plate disposed inside the feed hopper, a discharge port on one side of the housing, a guide plate fixedly disposed inside the discharge port, one side of the guide plate contacting the conveyor belt, a drying assembly disposed on the housing, the drying assembly comprising multiple air outlet pipes evenly distributed, the multiple air outlet pipes being fixedly disposed on the inner walls of the front and rear sides of the housing, a hot air fan fixedly disposed at the bottom of the housing, the hot air fan being connected to the multiple air outlet pipes through branch pipes.
[0007] In a preferred embodiment, the feed hopper and the cover plate are connected by multiple damping spring dampers. The multiple damping spring dampers are evenly distributed on the feed hopper. The multiple damping spring dampers can support the stable placement of the feed hopper. At the same time, the damping spring dampers can buffer vibration impact and reduce vibration transmission rate.
[0008] In a preferred embodiment, a vibration motor is fixedly installed on both outer walls of the feed hopper. The vibration motor is located above the damping spring damper. The vibration motor drives the feed hopper and the filter plate to vibrate, which can break up the lumpy raw materials and thus improve the filtration efficiency.
[0009] In a preferred embodiment, electric push rods are fixedly provided on both outer walls of the housing, and connecting plates are fixedly provided at the top of the piston rods of the two electric push rods. The connecting plates are fixed to the cover plate, and the cover plate is automatically raised and lowered by the electric push rods, which facilitates the cleaning of the inside of the housing by the staff.
[0010] In a preferred embodiment, the bottom of the housing is fixedly provided with multiple support legs, which are distributed on the outside of the hot air blower to improve the stability of the housing.
[0011] In a preferred embodiment, a pressure relief valve is fixedly inserted through the top of the cover plate. The pressure relief valve is connected to the inside of the housing and an air purifier is connected to it. The air purifier is fixed to the top of the cover plate and balances the air pressure inside the housing through the pressure relief valve. At the same time, the air purifier can filter the gas discharged from the pressure relief valve to prevent harmful gases from polluting the working environment.
[0012] A reaction apparatus for preparing a precious metal catalyst includes a granulator. The granulator has a feed inlet on one side of its top, and a protective cover is fitted on the outer wall of the feed inlet. The granulator is detachably connected to the aforementioned feeding mechanism through the protective cover.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. This utility model guides the precious metal catalyst raw material to fall evenly onto the conveyor belt through the feed hopper. At the same time, the vibrating feed hopper and filter plate can disperse the lumpy raw material, which can not only improve the filtration efficiency, but also facilitate subsequent preparation. Furthermore, the hot air blown out by multiple air outlets can dry the raw material, preventing the precious metal catalyst from becoming damp and clumping, which would affect subsequent production.
[0015] 2. By installing a damping spring vibration damper between the feed hopper and the shell, the damping spring vibration damper can buffer the vibration impact between the feed hopper and the cover plate and the shell.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Refer to the instruction manual appendix Figures 1-5This utility model provides a feeding mechanism, including a housing 1 and a conveyor belt 2 disposed inside the housing 1. The top of the housing 1 is provided with a cover plate 3, and a feed hopper 4 passes through one side of the top of the cover plate 3. A filter plate 5 is disposed inside the feed hopper 4. A discharge port 6 is opened on one side of the housing 1. A guide plate 7 is fixedly disposed inside the discharge port 6. One side of the guide plate 7 is in contact with the conveyor belt 2. A drying assembly 8 is provided on the housing 1. The drying assembly 8 includes a plurality of air outlet pipes 81 distributed at equal intervals. The plurality of air outlet pipes 81 are respectively fixed on the inner walls of the front and rear sides of the housing 1. A hot air blower 82 is fixedly disposed at the bottom of the housing 1. The hot air blower 82 is connected to the plurality of air outlet pipes 81 through a branch pipe 83.
[0025] Vibration motors 10 are fixedly installed on both outer walls of the feed hopper 4. The vibration motors 10 are located above the damping spring damper 9. Multiple support legs 13 are fixedly installed at the bottom of the housing 1. The multiple support legs 13 are distributed on the outside of the hot air blower 82.
[0026] In actual use, the precious metal catalyst raw material is first poured into the feed hopper 4. After being filtered by the filter plate 5, the raw material falls from below the feed hopper 4 onto the conveyor belt 2. At the same time, two vibrating motors 10 drive the feed hopper 4 to vibrate. When the filter plate 5 vibrates, it can disperse the lumpy raw material and prevent the lumpy raw material from clogging the filter plate 5 and affecting the filtration efficiency. After filtration, it is conveyed to the conveyor belt 2 through the feed hopper 4. The conveyor belt 2 transfers the precious metal catalyst to the guide plate 7 and is conveyed out through the guide plate 7 and the discharge port 6. During the conveying process, a hot air blower 82 is used to deliver hot air to multiple air outlet pipes 81 through the branch pipe 83. The hot air blown out can dry the precious metal catalyst raw material on the conveyor belt 2 and prevent the precious metal catalyst from being damp and clumping, which would affect subsequent production.
[0027] To reduce the impact of the vibration of the feed hopper 4 on the shell 1, such as Figure 1 and Figure 4 As shown, multiple damping spring dampers 9 are connected between the feed hopper 4 and the cover plate 3. The multiple damping spring dampers 9 are evenly distributed on the feed hopper 4. When the feed hopper 4 vibrates, the springs in the damping spring dampers 9 undergo elastic deformation due to the external excitation force, converting the vibration kinetic energy into the elastic potential energy of the spring, thereby buffering the vibration impact and reducing the vibration transmission rate.
[0028] In this embodiment, as Figures 1-4 As shown, electric push rods 11 are fixedly installed on both outer walls of the housing 1. Connecting plates 12 are fixedly installed at the top of the piston rods of the two electric push rods 11. The connecting plates 12 are fixed to the cover plate 3. After the feeding is completed, the electric push rods 11 are extended to drive the cover plate 3 to rise. After the cover plate 3 is separated from the housing 1, it is convenient for the staff to clean the conveyor belt 2 so as to avoid the raw material residue affecting the subsequent raw material quantity.
[0029] In this embodiment, as Figure 1 As shown, a pressure relief valve 14 is fixedly inserted through the top of the cover plate 3. The pressure relief valve 14 is connected to the inside of the housing 1 and is connected to an air purifier 15. The air purifier 15 is fixed to the top of the cover plate 3. The pressure relief valve 14 can discharge the gas inside the housing 1 to avoid excessive air pressure affecting the air pressure balance inside the housing 1. At the same time, the gas discharged through the pressure relief valve 14 is discharged after being purified by the air purifier 15, which can prevent harmful gases from polluting the working environment.
[0030] Refer to the instruction manual appendix Figure 1 and Figure 5 This utility model provides a reaction device for preparing a precious metal catalyst, including a granulator 16. The granulator 16 has a feed inlet 17 on one side of its top. The outer wall of the feed inlet 17 is fitted with a protective cover 18. The granulator 16 is detachably connected to the above-mentioned feeding mechanism through the protective cover 18.
[0031] When preparing precious metal catalysts, the operator first connects the top left side of the granulator 16 to the right side of the guide plate 7, and then connects the protective cover 18 on the top of the granulator 16 to the shell 1. The conveyor belt 2 inside the shell 1 can then be used to transport the precious metal catalyst raw materials, thereby achieving automatic feeding and improving the preparation efficiency of the granulator 16.
[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
