Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a solid-liquid mixing reaction vessel. Background Technology

[0002] A solid-liquid mixing reactor is a device used to mix solid and liquid materials and carry out chemical reactions. It is widely used in chemical, pharmaceutical, food, and environmental protection industries. In the chemical industry, many chemical synthesis reactions rely on solid-liquid mixing to drive the reaction process. In the pharmaceutical field, drug synthesis and purification processes require stringent precision in solid-liquid mixing reactions. In the food industry, the formulation of sauces and beverages also relies on efficient solid-liquid mixing operations. Chinese Patent CN220091382U discloses a reactor for solid-liquid mixing. By setting a support base below the reactor body and placing the reactor body on two movable plates, when the reactor body experiences significant vibration due to impact, the bottom sides of the movable plates apply pressure to the support rods. The support rods, through hinges at both ends, allow the connecting pipes connected to the bottom of the support rods to move laterally on guide rods. The connecting pipes apply pressure to the outer return springs. Under the action of the return springs, the vibration of the movable plates and the reactor body located on the movable plates is effectively damped, making the reactor body more stable on the support base. However, in the aforementioned solid-liquid mixing reactor, the liquid and solid often enter the reactor simultaneously. Due to the density difference between the solid and liquid, the solid material easily settles rapidly under gravity after entering the reactor. Before the stirring equipment can fully function, a large amount of solid has already settled at the bottom of the reactor, making it difficult for the solid and liquid to fully contact and mix. This ultimately leads to uneven mixing, severely restricting the improvement of product quality and the efficient advancement of the production process. Therefore, it is necessary to invent a solid-liquid mixing reactor. Summary of the Invention

[0003] The purpose of this utility model is to provide a solid-liquid mixing reactor to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: A solid-liquid mixing reactor, including a bottom plate, a water tank and a reactor body fixedly mounted on the top of the bottom plate, a cone-shaped structure connected to the bottom of the reactor body, a discharge port connected to the bottom of the cone-shaped structure, a hollow column fixedly mounted on the top of the reactor body, a long rod rotatably mounted inside the hollow column, a spiral blade fixedly mounted on the outer wall of the long rod, a discharge port fixedly mounted on the top of one end of the hollow column, the discharge port penetrating the reactor body, a long shaft rotatably mounted inside the reactor body, multiple stirring rods fixedly mounted on the outer wall of the long shaft, a scraper rod 1 fixedly mounted at both ends of each stirring rod, a scraper rod 2 and a connecting column fixedly mounted at the bottom of one of the stirring rods, a scraper rod 3 fixedly mounted at the other end of the connecting column, a hollow plate 1 and a hollow plate 2 fixedly mounted on the inner wall of the top of the reactor body, multiple inclined nozzles 1 and 2 connected to the bottom of the hollow plate 1, and multiple nozzles 3 connected to the bottom of the hollow plate 2.

A scraper 241 is fixedly mounted at both ends of each stirring rod 24. A scraper 242 and a connecting column 243 are fixedly mounted at the bottom of one of the stirring rods 24. The other end of the connecting column 243 is fixedly provided with a scraper 244. Hollow plates 1-18 and 2-183 are fixedly provided on the top inner wall of the vessel body 13. Multiple inclined nozzles 1-181 and 2-182 are connected to the bottom of hollow plate 1-183, and multiple nozzles 3-184 are connected to the bottom of hollow plate 2-183. An electromagnetic valve is provided inside the discharge port 17. When the electromagnetic valve is open, the solid-liquid mixture flows out; when the electromagnetic valve is closed, the solid-liquid mixture is prevented from flowing out. Furthermore, an L-shaped plate 19 is fixedly provided on the top of the vessel body 13. A bevel gear 23 is rotatably provided on the bottom of the L-shaped plate 19. The top of the long shaft 231 passes through the vessel body 13 and is fixedly connected to the bevel gear 23. Furthermore, a second bevel gear 26 is rotatably mounted on one side of the L-shaped plate 19, and a first bevel gear 23 meshes with the second bevel gear 26. One end of the long rod 27 passes through the hollow column 15 and is fixedly connected to the L-shaped plate 19 and the second bevel gear 26, facilitating the rotation of the long rod 27. Furthermore, a motor 21 is fixedly mounted on the top of the L-shaped plate 19, and the output shaft of the motor 21 passes through the L-shaped plate 19 and is fixedly connected to the first bevel gear 23, facilitating the rotation of the first bevel gear 23. Furthermore, a water pump 31 is fixedly installed inside the water tank 11. An L-shaped pipe 32 is connected to the top of the water pump 31, penetrating the water tank 11. Short pipes 33 and 34 are connected to the bottom of the L-shaped pipe 32. Short pipe 33 penetrates the vessel body 13 and connects to a hollow plate 18. Short pipe 34 penetrates the vessel body 13 and connects to a hollow plate 18, facilitating liquid ejection. Furthermore, a rectangular groove 12 is formed in the vessel body 13, and a discharge port 17 penetrates the rectangular groove 12. Furthermore, a support rod 14 is fixedly installed at the top of the water tank 11, and the support rod 14 is fixedly connected to a hollow column 15. A feed inlet 16 is formed at the top of the hollow column 15 for easy fixation.Working principle: In operation, the solid material is first placed inside the hollow column 15. Then, the motor 21 is started, which drives the first bevel gear 23 to rotate. This, in turn, drives the second bevel gear 26 and the long rod 27 to rotate, which in turn drives the connected spiral blades 271 to rotate. Under the action of the spiral blades 271, the solid material can smoothly enter the interior of the vessel body 13 from the hollow column 15 through the feed port 17. For the liquid portion requiring mixing, it can first be stored in water tank 11. Powered by water pump 31, the liquid is transported via L-shaped pipe 32, then through short pipe 33 and short pipe 34 to hollow plate 18 and hollow plate 183 respectively. Finally, the liquid is sprayed out through inclined nozzles 181, 182, and 184. Inclined nozzle 181 is positioned directly above the discharge port 17, ensuring full contact between the liquid and the solid material falling from the discharge port 17. This not only ensures a more uniform mixture of the solid and liquid materials but also effectively disperses the solid material due to the impact of the liquid, preventing agglomeration and significantly improving mixing efficiency and reaction efficiency. When bevel gear 23 rotates, it drives long shaft 231 and stirring rod 24 to rotate, enabling efficient mixing of solid and liquid raw materials within the vessel 13 and significantly improving stirring efficiency. While rotating, scraper 241 rotates synchronously, closely adhering to the inner wall of the vessel 13, effectively scraping away material adhering to the inner wall and significantly reducing material residue. At the same time, the rotation of stirring rod 24 also drives scraper 242 to rotate, scraping and cleaning the inner wall of discharge port 132, reducing material residue on the inner wall of discharge port 132 and effectively preventing blockage. When stirring rod 24 rotates, it drives scraper 244 to rotate, adhering to the inner wall of cone 131, facilitating cleaning of cone 131, reducing material residue, and further improving the overall stirring effect.
