Description

Technical Field

[0001] This utility model relates to the field of catalytic reaction device technology, and in particular to a catalytic reaction device for the production of chloromethyl isopropyl carbonate. Background Technology

[0002] Chloromethyl isopropyl carbonate is an important organic synthesis intermediate with wide applications in pharmaceuticals, new energy, and other fields. Its preparation typically involves a reactor where, after the raw materials are added, the temperature is controlled and the mixture is stirred and stirred. After the reaction is complete, the reaction solution is desolvated, and the residue in the reactor becomes the catalyst. Both the solvent and catalyst can be recycled.

[0003] In existing technologies, when chloromethyl isopropyl carbonate is produced in a reactor, its stirring structure can only rotate within the reactor. Its stirring effect on the raw materials within the reactor is limited to the current horizontal level. Therefore, it cannot effectively stir the raw materials at different heights within the reactor, which in turn affects the catalytic production effect of chloromethyl isopropyl carbonate and has certain limitations in its application.

[0004] Therefore, it is necessary to provide a catalytic reaction apparatus for the production of chloromethyl isopropyl carbonate to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a catalytic reaction apparatus for the production of chloromethyl isopropyl carbonate, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a catalytic reaction device for the production of chloromethyl isopropyl carbonate, comprising a vessel body and an end cap adapted to the vessel body, wherein a stirring shaft extending into the vessel body is movably disposed on the end cap, and a control component for driving the stirring shaft is disposed on the end cap.

[0007] The control components include a motor fixedly mounted on the end cover, a turntable fixedly mounted on the output shaft of the motor, a rotating part shared between the turntable, the stirring shaft and the end cover, and a lifting part shared between the turntable and the stirring shaft. When the motor is started and drives the turntable to rotate, the turntable drives the stirring shaft to rotate through the rotating part and drives the stirring shaft to move up and down along the vessel body through the lifting part.

[0008] As a further embodiment of this utility model: the rotating part includes a gear ring fixedly mounted on the turntable and a gear rotatably mounted on the top of the end cover. The gear is connected to the gear ring in a transmission manner, and the gear is coaxially driven with the stirring shaft.

[0009] As a further embodiment of this utility model: the stirring shaft and the gear are assembled by a key shaft, the stirring shaft can rotate synchronously with the gear, and the stirring shaft can move along the axial direction of the gear.

[0010] As a further embodiment of this utility model: the lifting part includes a clamp movably sleeved on the outer surface of the stirring shaft and a sleeve rod rotatably mounted on the turntable, and a bracket that slides with the sleeve rod is fixedly installed on the surface of the clamp.

[0011] As a further embodiment of this utility model: the outer surface of the stirring shaft is provided with an annular groove for the clamp to be movably fitted, so that the clamp and the stirring shaft can be raised and lowered synchronously through the annular groove.

[0012] As a further embodiment of this utility model: the bracket is U-shaped in shape and the sleeve is slidably engaged in the U-shaped opening of the bracket, and the sleeve is rotatably installed at the end of the turntable near the stirring shaft.

[0013] As a further embodiment of this utility model, several material tubes are fixedly connected to the end cap.

[0014] Compared with the prior art, the beneficial effects of this utility model are: through the cooperation between the end cap, stirring shaft and control components, the stirring shaft can be driven to rotate and rise and fall in the reactor body at the same time, thereby achieving effective stirring of raw materials at different heights in the reactor body, avoiding the phenomenon of uneven stirring in the upper, middle and lower layers, effectively improving the stirring and mixing effect of raw materials in the reactor body, thus ensuring the efficient production of chloromethyl isopropyl carbonate, and the overall practicality is higher.

[0022] Example 1:

[0023] Please see Figures 1 to 2 This utility model provides a catalytic reaction device for the production of chloromethyl isopropyl carbonate, mainly used to improve the stirring and mixing effect of the stirring shaft 3 on the raw materials in the vessel body 1. The device includes a vessel body 1 and an end cover 2 adapted to the vessel body 1. The stirring shaft 3, which extends into the vessel body 1, is movably mounted on the end cover 2. When the stirring shaft 3 is inserted into the vessel body 1 and rotates, it can achieve a stirring effect. Its stirring blades are existing technology and are not shown in the figure. The end cover 2 is provided with a control component 5 for driving the stirring shaft 3, thereby providing power to the stirring shaft 3.

[0024] Among them, the control component 5 can drive the stirring shaft 3 to rotate and lift based on the end cover 2. During the rotation, the raw materials on the corresponding horizontal plane in the vessel body 1 can be effectively stirred. When lifting and lowering at the same time, the raw materials on different horizontal planes in the vessel body 1 can be effectively stirred, thereby effectively improving the stirring and mixing effect of the raw materials in the vessel body 1, so as to ensure the efficient manufacturing of chloromethyl isopropyl carbonate.

[0025] Furthermore, such as Figure 1 As shown, several material pipes 4 are fixedly connected to the end cap 2. The material pipes 4 can be used to feed raw materials into the reactor body 1 and to output materials from the reactor body 1, thereby improving the overall production efficiency. The material pipes 4 are existing mature technologies and will not be described in detail here.

[0026] In summary, through the cooperation of the end cap 2, stirring shaft 3, and control components 5, the stirring shaft 3 can be driven to rotate and rise and fall simultaneously within the vessel body 1. This enables effective stirring of raw materials at different heights within the vessel body 1, avoiding uneven stirring due to stratification at the top, middle, and bottom. It effectively improves the stirring and mixing effect of the raw materials within the vessel body 1, thereby ensuring the efficient manufacturing of chloromethyl isopropyl carbonate and enhancing its overall practicality.

[0027] Example 2:

[0028] Please see Figures 1 to 5 Based on Embodiment 1, the control component 5 includes a motor 501 fixedly mounted on the end cover 2. A turntable 502 is fixedly mounted on the output shaft of the motor 501. A rotating part is provided between the turntable 502, the stirring shaft 3, and the end cover 2. A lifting part is provided between the turntable 502 and the stirring shaft 3. When the motor 501 starts and drives the turntable 502 to rotate, the turntable 502 drives the stirring shaft 3 to rotate continuously through the rotating part, thereby realizing the stirring of the raw materials in the vessel 1. On the other hand, the turntable 502 drives the stirring shaft 3 to rise and fall along the vessel 1 through the lifting part, thereby realizing the effective stirring of raw materials at different heights in the vessel 1.

[0029] It should be noted that the motor 501 in this embodiment is a servo motor 501 capable of forward and reverse rotation, which drives the turntable 502 to rotate in both directions, thereby driving the stirring shaft 3 to complete the lifting and lowering through the lifting part.

[0030] Furthermore, refer to Figures 2 to 5 In this embodiment, preferably, the rotating part includes a gear ring 504 fixedly mounted on the turntable 502 and a gear 503 rotatably mounted on the top of the end cover 2. The gear 503 is connected to the gear ring 504 to transmit the rotation of the turntable 502 to the gear 503. The gear 503 is coaxially driven with the stirring shaft 3, so the gear 503 can transmit the rotation to the stirring shaft 3, thereby realizing the continuous rotation of the stirring shaft 3.

[0031] In the above structure, such as Figure 3 As shown, the stirring shaft 3 and the gear 503 are assembled using a key shaft type. Specifically, a shaft rod 302 can be fixedly installed on the stirring shaft 3. At this time, the stirring shaft 3 can rotate synchronously with the gear 503, and the stirring shaft 3 can move accordingly along the axial direction of the gear 503, that is, the stirring shaft 3 can move up and down accordingly.

[0032] It should be noted that gear 503 and gear ring 504 serve to transmit the rotation of turntable 502 to gear 503. In practical applications, gear 503 and gear ring 504 can be replaced with bevel gear 503 or other existing mechanisms that can transmit power.

[0033] Furthermore, refer to Figures 2 to 5 In this embodiment, preferably, the lifting part includes a clamp 506 movably sleeved on the outer surface of the stirring shaft 3 and a sleeve rod 507 rotatably mounted on the turntable 502. A bracket 505 that slides with the sleeve rod 507 is fixedly installed on the surface of the clamp 506. When the turntable 502 drives the sleeve rod 507 to rotate, the stirring shaft 3 can be driven to rise and fall based on the end cover 2 through the bracket 505 and the clamp 506.

[0034] Among them, such as Figure 3 As shown, the outer surface of the stirring shaft 3 is provided with an annular groove 301 for the clamp 506 to be movably fitted. The annular groove 301 prevents the clamp 506 from rotating synchronously with the stirring shaft 3, but the clamp 506 can drive the stirring shaft 3 to move up and down synchronously when it is raised and lowered.

[0035] In the above structure, such as Figure 4 As shown, the bracket 505 has a U-shaped design and a certain length. The sleeve rod 507 is slidably engaged in the U-shaped opening of the bracket 505. At the same time, the sleeve rod 507 is rotatably installed on the end of the turntable 502 near the stirring shaft 3, rather than on the outer surface. When the turntable 502 rotates and drives the sleeve rod 507 to move, the sleeve rod 507 can slide along the length direction of the bracket 505, and at the same time drive the bracket 505 and the clamp 506 to rise and fall synchronously.

[0036] In use, the raw materials are first fed into the vessel body 1 through part of the feed pipe 4 and the motor 501 is started at the same time. The motor 501 drives the turntable 502, the gear ring 504 and the sleeve rod 507 to rotate synchronously. The gear ring 504 can drive the stirring shaft 3 to rotate synchronously through the gear 503, thereby stirring the raw materials in the vessel body 1. The sleeve rod 507 drives the stirring shaft 3 to move up and down on the basis of rotation through the bracket 505 and the clamp 506, thereby realizing the effective stirring of raw materials at different heights in the vessel body 1, which can effectively improve the stirring and mixing effect of the raw materials in the vessel body 1.

[0037] In this embodiment, the combination of structures such as turntable 502, sleeve rod 507, bracket 505 and gear 503 can drive the stirring shaft 3 to rotate and rise and fall in the vessel body 1, thereby achieving effective stirring of raw materials at different heights in the vessel body 1, avoiding uneven stirring of upper, middle and lower layers, and effectively improving the stirring and mixing effect of raw materials in the vessel body 1, thereby ensuring the efficient manufacturing of chloromethyl isopropyl carbonate.

[0038] The overall structure is integrated into the top of the end cap 2, which has a simple and clear structure, making it easy to carry out subsequent maintenance and replacement, and reducing the burden of subsequent cleaning operations, thus making it more practical overall.
