Description

Technical Field

[0001] This utility model relates to the field of catalyst production technology, specifically a cooling device for desulfurization catalyst production. Background Technology

[0002] In a chemical reaction, a substance that can change the rate of a chemical reaction without altering the chemical equilibrium, and whose mass and chemical properties remain unchanged before and after the reaction, is called a catalyst. It is estimated that catalysts are used in over 90% of industrial processes, such as chemical, petrochemical, biochemical, and environmental protection industries. The effect of a catalyst in a chemical reaction is called catalysis. Solid catalysts are also known as catalysts in industry. The composition, chemical properties, and mass of a catalyst do not change before and after the reaction. Its relationship with the reaction system is like that of a lock and a key, exhibiting high selectivity. A catalyst does not necessarily catalyze all chemical reactions. For example, manganese dioxide catalyzes the thermal decomposition of potassium chlorate, accelerating the chemical reaction rate, but it may not catalyze other chemical reactions.

[0003] Cooling devices are required in the production process of desulfurization catalysts. A search revealed a patent document with publication number CN208824322U, which discloses a cooling device for chemical catalyst production. This device includes a main body, a stirring rod, a rotating shaft, a top cover, an air intake fan, cooling pipes, and a stirring motor. Support frames are welded to both sides of the bottom surface of the main body, and a walking platform is welded to the bottom of the support frames. A stirring motor is bolted to the center of the bottom surface of the main body, and cooling pipes are installed on the inner bottom surface. This invention uses the stirring motor to rotate the stirring rod, thereby stirring the accumulated catalyst and promoting heat dissipation. Adding cooling water to the cooling pipes cools the catalyst at the bottom. The air intake fan, located at the top of the top cover, draws in cooler outside air to cool the catalyst on the outermost layer.

[0004] The stirring structure in the current cooling device is simple and the stirring range is limited, which makes it impossible to efficiently stir the catalyst inside the device, thus reducing the cooling efficiency. Therefore, a cooling device for desulfurization catalyst production is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cooling device for desulfurization catalyst production, which has advantages such as improved cooling efficiency. It solves the problem that existing cooling devices for catalyst production have a simple stirring structure and a limited stirring range, which cannot efficiently stir the catalyst inside the reactor, thus reducing cooling efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cooling device for the production of desulfurization catalyst, comprising a base frame, a support frame fixedly installed on the top of the base frame, a cooling tank fixedly installed on the top of the support frame, and a stirring mechanism provided on the upper side of the cooling tank;

[0007] The stirring mechanism includes a mounting bracket disposed outside the cooling tank and a top plate disposed on the top of the cooling tank. A mounting tube extending to the inner side of the top plate is fixedly mounted on the mounting bracket. A fixed gear is fixedly mounted on the outer wall of the mounting tube. A stirring shaft is rotatably mounted on the top plate. A first transmission gear that meshes with the fixed gear is fixedly mounted on the upper end of the stirring shaft. Blades are fixedly mounted on the lower side wall of the stirring shaft. A drive motor is fixedly mounted on the top of the mounting bracket. A connecting shaft is fixedly mounted on the output shaft of the drive motor. A second transmission gear is fixedly mounted on the lower end of the connecting shaft. A gear ring that meshes with the second transmission gear is fixedly mounted on the top of the top plate.

[0008] Furthermore, a refrigeration unit is installed on the outside of the base frame, and an air pump is fixedly installed on the top of the refrigeration unit.

[0009] Furthermore, a cooling pipe is installed at the air supply end of the air pump, and the end of the cooling pipe away from the air pump is connected to the cooling tank.

[0010] Furthermore, an exhaust pipe and a thermometer are respectively installed on the side wall of the cooling tank, and a discharge pipe is installed at the bottom of the cooling tank.

[0011] Furthermore, a support ring is fixedly installed on the inner wall of the cooling tank, and the top plate is rotatably installed on top of the support ring.

[0012] Furthermore, the top plate is provided with a material inlet corresponding to the installation pipe.

[0013] Furthermore, the number of blades is set to multiple, and the multiple blades are symmetrically distributed on both sides of the stirring shaft.

[0014] Furthermore, the stirring shaft and the first transmission gear are offset from the center position of the top plate, while the center positions of the fixed gear, the gear ring, and the top plate are all located on the same axis.

[0015] Compared with the prior art, the present invention provides a cooling device for the production of desulfurization catalysts, which has the following beneficial effects:

[0016] This cooling device for desulfurization catalyst production, through the cooperation of a drive motor, a second transmission gear, and a gear ring, can drive the top plate to rotate. Through the cooperation of the first transmission gear and the fixed gear, the rotation of the top plate can drive the blades to make a circular motion while rotating, thereby increasing the stirring range and facilitating efficient stirring of the catalyst inside the cooling tank. This improves the cooling effect on the catalyst and solves the problem that the existing cooling devices for catalyst production have a single stirring structure and a single stirring range, which cannot efficiently stir the catalyst inside the device and reduces the cooling efficiency.

[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] Please see Figures 1 to 5 A cooling device for desulfurization catalyst production in this embodiment includes a base frame 1, a support frame 2 fixedly installed on the top of the base frame 1, and a cooling tank 3 fixedly installed on the top of the support frame 2.

[0025] The base frame 1 is equipped with a refrigeration unit 4. A gas pump 5 is fixedly installed on the top of the refrigeration unit 4. A cooling pipe 6 is installed at the gas supply end of the gas pump 5. The end of the cooling pipe 6 away from the gas pump 5 is connected to the cooling tank 3. Through the cooperation of the gas pump 5 and the cooling pipe 6, the cold air generated by the refrigeration unit 4 can be delivered to the interior of the cooling tank 3, which facilitates the cooling of the catalyst inside the cooling tank 3.

[0026] It should be noted that an exhaust pipe 20 and a thermometer 21 are respectively installed on the side wall of the cooling tank 3. The exhaust pipe 20 is connected to an external exhaust pipe to facilitate the discharge of hot air exchanged inside the cooling tank 3. The thermometer 21 is used to detect the temperature of the catalyst inside the cooling tank 3 to ensure that the catalyst is completely cooled before discharge. A discharge pipe 11 is installed at the bottom of the cooling tank 3. A valve can be installed on the discharge pipe 11 to facilitate the control of the opening and closing of the pipeline.

[0027] In this embodiment, a stirring mechanism is provided on the upper side of the cooling tank 3. The stirring mechanism includes a mounting frame 7 disposed on the outside of the cooling tank 3 and a top plate 8 disposed on the top of the cooling tank 3. A mounting tube 10 extending to the inner side of the top plate 8 is fixedly mounted on the mounting frame 7. A fixed gear 12 is fixedly mounted on the outer wall of the mounting tube 10. A stirring shaft 13 is rotatably mounted on the top plate 8. The stirring shaft 13 is connected to the top plate 8 through a bearing. A first transmission gear 14 that meshes with the fixed gear 12 is fixedly mounted on the upper end of the stirring shaft 13. When the first transmission gear 14 moves in a circular motion around the fixed gear 12, since the fixed gear 12 follows the mounting tube 10 and remains fixed, the first transmission gear 14 moves in a circular motion and rotates around the fixed gear 12 under the meshing of the fixed gear 12 and the first transmission gear 14, thereby driving the stirring shaft 13 to rotate. A blade 15 is fixedly mounted on the lower side wall of the stirring shaft 13, thereby driving the blade 15 to rotate, and using the blade 15 to stir the catalyst inside the cooling tank 3. A drive motor 16 is fixedly mounted on the top of the mounting bracket 7. A connecting shaft 17 is fixedly mounted on the output shaft of the drive motor 16. A second transmission gear 18 is fixedly mounted on the lower end of the connecting shaft 17. A gear ring 19 that meshes with the second transmission gear 18 is fixedly mounted on the top of the top plate 8. By starting the drive motor 16, the connecting shaft 17 can be driven to rotate. When the connecting shaft 17 rotates, it can drive the second transmission gear 18 to rotate. The second transmission gear 18 can drive the gear ring 19 to rotate. The gear ring 19 will then drive the top plate 8 to rotate synchronously, so as to drive the stirring shaft 13 and the first transmission gear 14 to move and rotate around the fixed gear 12.

[0028] The stirring shaft 13 and the first transmission gear 14 are offset from the center of the top plate 8. The fixed gear 12, the gear ring 19 and the center of the top plate 8 are all located on the same axis. When the drive motor 16 drives the connecting shaft 17 to rotate, it can drive the second transmission gear 18 to rotate. The second transmission gear 18 can drive the gear ring 19 to rotate. The gear ring 19 will drive the top plate 8 to rotate synchronously. When the top plate 8 rotates, it can drive the first transmission gear 14 on the stirring shaft 13 to move and rotate around the fixed gear 12, thereby driving the stirring shaft 13 to rotate. This, in turn, drives the blades 15 to move in a circle and rotate at the same time, improving the stirring range and facilitating efficient stirring of the catalyst inside the cooling tank 3.

[0029] The cooling tank 3 has a support ring 9 fixedly installed on its inner wall. The top plate 8 is rotatably installed on the top of the support ring 9. The top plate 8 and the support ring 9 can be connected by a bearing. Alternatively, an annular track can be opened on the top of the support ring 9. The bottom of the top plate 8 is provided with a slider that cooperates with the annular track, thereby ensuring the stable rotation of the top plate 8.

[0030] It should be noted that the top plate 8 is provided with a feed port 22 corresponding to the mounting pipe 10. The diameter of the feed port 22 is larger than that of the mounting pipe 10. At the same time, the feed port 22 and the mounting pipe 10 can be connected by a sealed bearing to prevent the fixedly installed mounting pipe 10 from interfering with the rotation of the top plate 8. In addition, there are multiple blades 15, which are symmetrically distributed on both sides of the stirring shaft 13.

[0031] The working principle of the above embodiments is as follows:

[0032] In use, the catalyst is added into the cooling tank 3 through the installation pipe 10. The cold air generated by the refrigeration unit 4 is delivered into the cooling tank 3 through the cooperation of the air pump 5 and the cooling pipe 6. The drive motor 16 is started to drive the connecting shaft 17 to rotate. When the connecting shaft 17 rotates, it drives the second transmission gear 18 to rotate. The second transmission gear 18 drives the gear ring 19 to rotate. The gear ring 19 drives the top plate 8 to rotate synchronously. When the top plate 8 rotates, it drives the first transmission gear 14 on the stirring shaft 13 to move and rotate around the fixed gear 12, thereby driving the stirring shaft 13 to rotate. This, in turn, drives the blades 15 to move in a circle and rotate at the same time, which increases the stirring range and facilitates efficient stirring of the catalyst inside the cooling tank 3, thus improving the cooling effect of the catalyst.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.

[0034] The above description is a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and concept of this application, should be covered within the protection scope of the claims of this utility model.
