Description

Technical Field

[0001] This utility model relates to the field of hydrogen peroxide processing technology, specifically to a hydrogen peroxide catalyst addition device. Background Technology

[0002] Hydrogen peroxide, from a chemical perspective, is a compound with specific chemical composition and properties. Its chemical formula is H₂O₂. Analyzing its molecular structure, each hydrogen peroxide molecule consists of two hydrogen atoms (H) and two oxygen atoms (O) linked by specific chemical bonds. At room temperature and pressure, hydrogen peroxide is a colorless and transparent liquid, resembling ordinary water in appearance, but its chemical properties differ significantly from those of water.

[0003] The existing patent announcement number CN214106878U discloses a zeolite catalyst addition device for pyridine synthesis, including a reaction vessel. A feed pipe is installed at the upper end of the reaction vessel, and a one-way valve is mounted on the feed pipe. The end of the feed pipe away from the reaction vessel is connected to a connecting seat. The feed pipe is also mounted on a shaking mechanism, which is installed on the outer wall of the reaction vessel. The shaking mechanism includes a chassis, a support base, a drive motor, an eccentric wheel, a push rod, a clamp, and a support guide plate. This zeolite catalyst addition device for pyridine synthesis, through the shaking feed pipe, allows the added zeolite catalyst to enter the reaction vessel more effectively, preventing feed pipe blockage. This accelerates the pyridine synthesis speed and improves the pyridine synthesis efficiency. The sealing cap is connected to the connecting seat via an elastic connecting rope, making installation and removal of the sealing cap convenient and easy. The sealing cap seals the feed pipe, preventing dust and other debris from falling into the feed pipe and contaminating the reaction vessel.

[0004] While the above technical solution can control the catalyst feed and avoid clogging of the feed pipe, some reacted material will remain inside the reaction tank after the catalyst reacts with the raw materials. This residue may be added as impurities to the product of the next reaction, reducing the purity and quality of the final product. Therefore, we provide a hydrogen peroxide catalyst addition device.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] This utility model provides a technical solution: such as Figures 1-4 As shown, in this embodiment, a hydrogen peroxide catalyst addition device includes a reaction tank 11. A support 12 is provided on the top of the reaction tank 11, a motor 13 is provided on the top of the support 12, and a rotating shaft 14 is provided at the bottom of the motor 13. The support 12 is fixedly connected to the top of the reaction tank 11, and the top of the support 12 is fixedly installed to the bottom of the motor 13. The output end of the bottom of the motor 13 is fixedly connected to the top of the rotating shaft 14. Four connecting rods 15 are provided on the outside of the rotating shaft 14, and a rotating stirring rod 16 is provided on the outside of each of the four connecting rods 15. A cleaning scraper 17 is provided at the end of each of the four connecting rods 15 away from the rotating shaft 14. The bottom end of the rotating shaft 14 extends into the reaction tank 11. The ends of the four connecting rods 15 near the rotating shaft 14 are fixedly connected to the outside of the rotating shaft 14, and the cleaning scraper 17 is fixedly connected to the ends of the four connecting rods 15 away from the rotating shaft 14. A water tank 18 is provided on one side of the reaction tank 11. A water pump 19 is installed on the top of the water tank 18. Rotary stirring rods 16 are rotatably connected to the outside of the four connecting rods 15. The water pump 19 is fixedly installed on the top of the water tank 18. The input end of the water pump 19 extends into the water tank 18. A water pipe 110 is installed on one side of the water pump 19. An installation groove 111 is opened on the top side of the inner wall of the reaction tank 11. An annular spray head 112 is installed in the installation groove 111. The output end of the water pump 19 is fixedly connected to one end of the water pipe 110. The end of the water pipe 110 away from the water pump 19 extends into the reaction tank 11 and is fixedly connected to one side of the annular spray head 112. The top of the annular spray head 112 is fixedly installed in the installation groove 111. A load-bearing support frame 31 is fixedly connected to the outside of the bottom of the reaction tank 11. A feed inlet 32 ​​is provided on one side of the top of the reaction tank 11. A discharge valve 33 is provided at the bottom of the reaction tank 11. A stratification mechanism 2 is provided inside the reaction tank 11.

[0026] In this embodiment, when the device is used to process hydrogen peroxide and catalyst, hydrogen peroxide is first added to the reaction tank 11 through the feed inlet 32. The hydrogen peroxide level must be higher than the strainer 21. Then, the motor 13 is started to drive the rotating shaft 14 and connecting rod 15 to rotate and stir the hydrogen peroxide. Subsequently, the catalyst is added to the reaction tank 11 through the feed inlet 32. The rotating connecting rod 15 mixes and stirs the hydrogen peroxide and catalyst. When the connecting rod 15 rotates, the hydrogen peroxide will flow in a vortex shape. The rotating stirring rod 16 will then rotate along with the vortex flow, further mixing and stirring the hydrogen peroxide and catalyst. When the equipment is finished, it is in a state of... In the idle state, the water pump 19 can be started to draw water from the water tank 18 into the water pipe 110. The water pipe 110 transmits the water to the annular spray head 112, and the water is sprayed into the reaction tank 11 through the annular spray head 112 to clean the inside of the reaction tank 11 and the stirring mechanism. At the same time, the cleaning scraper 17 is set at the end of the connecting rod 15 near the inner wall of the tank. As the connecting rod 15 rotates, the cleaning scraper 17 can scrape the inner wall of the reaction tank 11. Combined with the sprayed water, the inner wall of the tank can be scrubbed to prevent some residual reaction materials inside the tank from forming impurities and mixing with the products of the next reaction, thus ensuring the quality and purity of the subsequent products.

[0027] like Figures 1-5 As shown, the layering mechanism 2 includes a mesh 21, the outside of which is fixedly connected to the inner wall of the reaction vessel 11, and two stirring plates 22 are fixedly connected to the rotating shaft 14 near the top of the mesh 21.

[0028] In this embodiment, when the catalyst is added to the reaction vessel 11, some solid catalyst may settle on the bottom side of the inner wall of the reaction vessel 11. The provided mesh screen 21 can block the solid catalyst in the middle of the reaction vessel 11, avoiding the solid catalyst from sinking to the bottom of the vessel and causing uneven mixing. When the rotating shaft 14 is rotated, the stirring plate 22 can beat and disperse the solid catalyst on the mesh screen 21, thus accelerating the reaction rate of the solid catalyst and hydrogen peroxide.

[0029] This utility model provides a hydrogen peroxide catalyst addition device, the specific working principle of which is as follows:

[0030] First, hydrogen peroxide is added to the reaction tank 11 through the feed inlet 32. During this process, special attention must be paid to controlling the hydrogen peroxide level, ensuring it is higher than the strainer 21. This is a crucial prerequisite for the smooth operation of subsequent stirring and mixing. After adding the hydrogen peroxide, the motor 13 is started. The motor 13, once running, will drive the rotating shaft 14 and its connected rod 15 to rotate. The rotation of the connecting rod 15 stirs the hydrogen peroxide in the reaction tank 11, allowing it to be distributed more evenly within the tank. Then… The catalyst is slowly added into the reaction vessel 11 through the feed inlet 32. As the catalyst enters the reaction vessel 11, the rotating connecting rod 15 performs its stirring function, thoroughly mixing the hydrogen peroxide and the catalyst. During this process, due to the continuous rotation of the connecting rod 15, the hydrogen peroxide forms a vortex flow inside the vessel. This vortex flow drives the rotating stirring rod to rotate as well. The rotation of the stirring rod further enhances the mixing effect of the hydrogen peroxide and the catalyst, allowing them to be more fully and evenly integrated together. When the entire processing is completed and the equipment is idle, a cleaning operation is required to ensure the equipment is clean and ready for the next use. At this time, water pump 19 can be started. After the water pump 19 starts, it will draw water from the water tank 18 and let it flow into the water pipe 110. Then, the water pipe 110 will stably transmit the drawn water to the annular spray head 112. Through the spray design of the annular spray head 112, the water will be evenly sprayed into the reaction tank 11. This sprayed water can not only rinse the inside of the reaction tank 11, but also... Effective cleaning of the stirring mechanism is achieved, while the cleaning scraper 17 plays a crucial role. It is located at the end of the connecting rod 15 near the inner wall of the tank. As the connecting rod 15 rotates, the cleaning scraper 17 can meticulously scrape the inner wall of the reaction tank 11. With the help of water spraying, the cleaning scraper 17 can better scrub the inner wall of the tank, effectively preventing some residual reactants inside the tank from forming impurities. This prevents these impurities from mixing with the product in the next reaction, thereby ensuring that the quality and purity of the subsequent product are not affected.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
