Description

Technical Field

[0001] This utility model relates to the field of catalyst preparation technology, specifically to a high-temperature resistant and toxic-resistant adjustable composite catalyst preparation device. Background Technology

[0002] In the preparation of high-temperature resistant and toxic-resistant tunable composite catalysts, flexible temperature control plays a crucial role in catalyst performance. However, current catalyst preparation equipment on the market has shortcomings in temperature control. Existing equipment often struggles to quickly and accurately switch reaction temperatures at different stages of preparation. In the high-temperature reaction stage, although the equipment can maintain a certain temperature, poor insulation design leads to significant heat loss, making it difficult to stably maintain a high-temperature environment. This results in catalyst performance degradation due to temperature fluctuations during synthesis. When the reaction is complete or temperature adjustment is required, the cooling process is slow and complex. Traditional equipment lacks effective heat dissipation and air circulation acceleration mechanisms. If cooling is needed, a long wait is often required, or cumbersome external cooling equipment must be used. This not only wastes a lot of time and energy but may also cause the catalyst performance to be affected by excessive heat due to untimely cooling. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides a high-temperature resistant and toxic-resistant adjustable composite catalyst preparation device. Its heat preservation device can effectively seal the interlayer space between the reactor and the insulation cylinder during normal reaction, reducing heat loss and stabilizing the high-temperature environment. When heat dissipation is required, the operator can easily lift and rotate the pull ring to make the blocking block leave the vent and fall into the positioning blind hole, achieving air circulation. Combined with the rotation device to accelerate air flow, the temperature is quickly reduced.

[0005] (II) Technical Solution

[0021] 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.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a high-temperature resistant and toxic-resistant adjustable composite catalyst preparation device, including a reaction device 1, the reaction device 1 including a base 11, an insulation cylinder 12 fixedly connected to the outer wall of the base 11, and a reaction vessel 13 fixedly connected to the inner wall of the insulation cylinder 12, and further including: a rotating device 2, the outer wall of the rotating device 2 being fixedly connected to the outer wall of the insulation cylinder 12; a heat preservation device 3, the outer wall of the heat preservation device 3 being rotatably connected to the outer wall of the insulation cylinder 12; the heat preservation device 3 including a rotating ring 31, a pulling ring 32 provided on the outer wall of the top of the rotating ring 31, a connecting rod 33 fixedly connected to the outer wall of the bottom of the pulling ring 32, a blocking block 35 fixedly connected to the end of the connecting rod 33 away from the pulling ring 32, and a compression spring 34 sleeved on the outside of the connecting rod 33, the walls of the rotating ring 31 and the pulling ring 32 being... All are provided with through holes 36. During normal reaction, the heat preservation device 3 can seal the interlayer space between the reactor 13 and the heat insulation cylinder 12 through the structure such as the blocking block 35 and the toothed ring 24, forming an area where air cannot circulate, effectively preventing heat loss, maintaining the high temperature environment inside the reactor 13, and ensuring that the preparation of the high temperature resistant catalyst is carried out at a stable temperature. When it is necessary to open the interlayer space for heat dissipation, the pull ring 32 is lifted upward, and the connecting rod 33 drives the blocking block 35 to move upward. At this time, the compression spring 34 is squeezed by the blocking block 35 and the rotating ring 31. When the blocking block 35 leaves the position of the vent 17, the pull ring 32 is rotated and the pull on the pull ring 32 is released until the blocking block 35 falls into the positioning blind hole 16 under the push of the compression spring 34, and the vent 17 is connected to the outside at this time.

[0023] The outer wall of the rotating ring 31 is rotatably connected to the outer wall of the top of the reactor 13, the inner wall of the rotating ring 31 is slidably connected to the outer wall of the connecting rod 33, one end of the compression spring 34 is fixedly connected to the outer wall of the blocking block 35, and the other end of the compression spring 34 is fixedly connected to the outer wall of the bottom of the rotating ring 31.

[0024] The reaction apparatus 1 also includes a DC motor 14, with a stirring rod 15 fixedly connected to the output end of the DC motor 14. A vent 17 is fixedly connected to the outer wall of the top of the reaction vessel 13. A positioning blind hole 16 is provided on the outer wall of the reaction vessel 13. A movable groove 18 is provided in the wall of the insulation cylinder 12. The outer wall of the bottom of the DC motor 14 is fixedly connected to the outer wall of the top of the reaction vessel 13. The outer wall of the stirring rod 15 is rotatably connected to the inner wall of the reaction vessel 13. The outer wall of the top of the vent 17 is slidably connected to the outer wall of the bottom of the rotating ring 31. The base 11 of the reaction apparatus 1 provides stable support for the entire device. The insulation cylinder 12 is fixed to the outer wall of the base 11. The interlayer space formed between it and the reactor 13 provides insulation for the reactor 13, reducing heat loss or external temperature interference. This helps maintain the stability of the high-temperature reaction environment inside the reactor 13. For composite catalysts, this ensures that the catalyst is synthesized under temperature conditions that are difficult to fluctuate, thereby improving the stability and performance of the catalyst. The DC motor 14 is fixed to the top of the reactor 13. The stirring rod 15 at its output end rotates inside the reactor 13, which can stir the reactants, making the raw materials fully mixed and promoting the chemical reaction.

[0025] The rotating device 2 includes a connecting frame 21. A servo motor 22 is fixedly connected to the outer wall of the bottom of the connecting frame 21. A drive gear 23 is fixedly connected to the output end of the servo motor 22. A gear ring 24 is provided on the outside of the servo motor 22. A threaded cylinder 25 is fixedly connected to the outer wall of the top of the gear ring 24. The inner side wall of the connecting frame 21 is fixedly connected to the side wall of the insulation cylinder 12. The outer wall of the drive gear 23 meshes with the gear ring 24. The outer wall of the drive gear 23 is rotatably connected to the inner wall of the insulation cylinder 12 through a movable groove 18. The inner side wall of the gear ring 24 is connected to the outer wall of the reaction vessel 13. The side wall of the part is rotatably connected, and the inner side wall of the threaded cylinder 25 is rotatably connected to the outer side wall of the reactor 13. The rotating device 2 is fixed to the side wall of the insulation cylinder 12 through the connecting frame 21. After the servo motor 22 is started, the drive gear 23 at its output end rotates. Since the drive gear 23 meshes with the gear ring 24, it drives the gear ring 24 to rotate. When the gear ring 24 rotates, the threaded cylinder 25 fixed at its top also rotates. The rotation of the threaded cylinder 25, by utilizing its threaded structure, accelerates the air flow speed in the jacket, quickly removes heat, and achieves the purpose of efficient cooling.

[0026] In use, the high-temperature resistant and toxic-resistant adjustable composite catalyst preparation equipment has a base 11 for the reaction device 1 that provides stable support for the entire equipment. The heat insulation cylinder 12 is fixed to the outer wall of the base 11, and the interlayer space formed between it and the reaction vessel 13 plays a role in heat insulation for the reaction vessel 13, reducing heat loss or external temperature interference, which is conducive to maintaining the stability of the high-temperature reaction environment inside the reaction vessel 13. For composite catalysts, it can ensure that the catalyst is synthesized under temperature conditions that are difficult to fluctuate, thereby improving the stability and performance of the catalyst. The DC motor 14 is fixed to the top of the reaction vessel 13, and the stirring rod 15 at its output end rotates inside the reaction vessel 13, which can stir the reaction materials, make the raw materials fully mixed, promote the chemical reaction, and improve the uniformity and efficiency of catalyst preparation. The vent 17 is used to assist the gas flow in the interlayer. The positioning blind hole 16 and the movable groove 18 are used in conjunction with other devices to realize the operation function of rapid cooling after heat preservation.

[0027] The rotating device 2 is fixed to the side wall of the insulation cylinder 12 via the connecting frame 21. After the servo motor 22 is started, the drive gear 23 at its output end rotates. Since the drive gear 23 meshes with the gear ring 24, it drives the gear ring 24 to rotate. When the gear ring 24 rotates, the threaded cylinder 25 fixed at its top also rotates. When it is necessary to accelerate the air flow in the space between the reactor 13 and the insulation cylinder 12 to achieve rapid cooling, the rotating device 2 plays a key role. The rotation of the threaded cylinder 25, using its threaded structure, accelerates the air flow speed in the space, quickly removes heat, and achieves efficient cooling. This helps to control the reaction process at the appropriate time and ensures that the performance of the catalyst is not continuously affected by excessively high temperatures.

[0028] The rotating ring 31 of the heat preservation device 3 is rotatably connected to the top of the reactor 13 and the outer wall of the insulation cylinder 12. During normal reaction, the heat preservation device 3, through structures such as the blocking block 35 and the toothed ring 24, can seal the interlayer space between the reactor 13 and the insulation cylinder 12, forming an area where air cannot circulate, effectively preventing heat loss and maintaining a high-temperature environment inside the reactor 13, ensuring that the preparation of the high-temperature resistant catalyst is carried out at a stable temperature. When it is necessary to open the interlayer space for heat dissipation, the pulling ring 32 is lifted upwards, and the connecting rod 33 drives the blocking block 35 to move upwards. At this time, the compression spring 34 is subjected to the force of the blocking block 35 and the rotating ring 31. When the blocking block 35 leaves the vent 17 position, the pulling ring 32 is rotated and the pulling of the pulling ring 32 is released until the blocking block 35 falls into the positioning blind hole 16 under the push of the compression spring 34. At this time, the vent 17 is connected to the outside. Air can enter the jacket through the through hole 36 in the wall of the rotating ring 31 and the pulling ring 32 to realize air circulation. Then, the rotating device 2 is started, and the threaded cylinder 25 rotates to accelerate the air flow and speed up the cooling rate. This makes it convenient to cool down the reactor 13 in time when the reaction is completed or the temperature needs to be adjusted, thereby improving the operational flexibility of the equipment and its adaptability to different preparation stages.
