Description

Technical Field

[0001] This application relates to the field of reactor technology, specifically to dimethylamine salt reactors. Background Technology

[0002] Dimethylamine salts are a class of salt compounds formed by the reaction of dimethylamine ((CH3)2NH) with acids. The most representative of these is dimethylamine hydrochloride (chemical formula C2H8ClN, CAS number 506-59-2).

[0003] A dimethylamine salt reactor is an industrial device specifically designed to handle chemical reactions related to dimethylamine salts. Its core function is to convert or recover dimethylamine salts by controlling reaction conditions.

[0004] For example, patent CN207614820U discloses a dimethylamine salt reactor for preparing N,N-dimethylaminoacrylate. This patent filters the items by connecting a filter screen inside the reaction chamber, ensuring the items are clean.

[0005] However, dimethylamine salts are prone to react with acidic substances under certain conditions to form insoluble salts, or crystallize due to temperature and concentration changes during distillation and reaction. These crystals tend to accumulate in the reactor, causing blockage in the discharge pipe during the discharge process. Poor discharge leads to material accumulation in the reactor, prolonging the reaction cycle and reducing the yield per unit time.

[0006] Therefore, it is necessary to provide a dimethylamine salt reactor to solve the above problems.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

Detailed Implementation

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0037] like Figures 1-2 As shown, this application provides a dimethylamine salt reactor, which is installed on the ground or a steel frame platform and is mainly used to synthesize compounds such as N,N-dimethylaminoacrylate. Specifically, the dimethylamine salt reactor includes a fixed frame 1 and a reactor 2 fixedly installed on the upper end of the fixed frame 1. The reactor 2 is the main place for chemical reactions.

[0038] The reactor 2 includes a fixed sleeve 20 fixedly installed on the upper end of the fixed frame 1, and a sealing plate 21 fixedly installed on the upper end of the fixed sleeve 20. At the same time, a reaction vessel 22 is fixedly installed inside the fixed sleeve 20. The reaction vessel 22 is used to store raw materials such as dimethylamine salt to be processed.

[0039] It should be noted that there is an insulation cavity (not shown in the figure) between the fixed sleeve 20 and the reaction vessel 22. At the same time, a water inlet 27 is fixedly installed on the upper end of one side of the fixed sleeve 20, and a drain outlet 28 is fixedly installed on the lower end of the other side of the fixed sleeve 20. The drain outlet 28 and the water inlet 27 are connected to the insulation cavity so that cooling water can be injected through the water inlet 27 during the reaction process to control the reaction temperature, and then the cooling water is discharged through the drain outlet 28.

[0040] Meanwhile, a feed inlet 23 is provided on the sealing plate 21. The feed inlet 23 is connected to the inside of the reaction vessel 22 so that raw materials such as dimethylamine salt can be introduced into the inside of the reaction vessel 22 through the feed inlet 23. An air inlet 29 is also provided on the sealing plate 21. The air inlet 29 is also connected to the inside of the reaction vessel 22 so that inert gas can be introduced into the inside of the reaction vessel 22 for use.

[0041] Furthermore, a discharge pipe 30 is fixedly installed at the lower end of the reaction vessel 22. The discharge pipe 30 extends through the fixed sleeve 20 to the outside to facilitate the discharge of reaction products.

[0042] To ensure a full reaction, a motor 24 is fixedly installed on the upper end of the sealing plate 21. The output of the motor 24 is fixedly connected to a stirring shaft 25. The stirring shaft 25 passes through the sealing plate 21 and extends into the interior of the reaction vessel 22. At the same time, a stirring paddle 26 is fixedly installed on the outside of the stirring shaft 25 so that during the reaction process, the stirring paddle 26 can be driven to rotate inside the reaction vessel 22 by starting the motor 24, thereby mixing the materials, accelerating the reaction, and preventing local overheating.

[0043] Before the mixing reaction begins, raw materials such as dimethylamine salt are first added through the feed inlet 23. Then, the motor 24 is started to drive the stirring paddle 26 to mix the materials. During the stirring process, cooling water is injected through the water inlet 27 to maintain the reaction temperature. In the mixing process, inert gas is introduced through the air inlet 29 to complete the subsequent reaction and mixing operations. Finally, the reactants are discharged through the discharge pipe 30.

[0044] To prevent blockages during the drainage process, such as Figures 1-4 As shown, an anti-blocking mechanism 4 is provided at the discharge pipe 30. This anti-blocking mechanism 4 prevents blockage by separately discharging the crystals and liquid.

[0045] The anti-clogging mechanism 4 includes multiple sets of springs 44 fixedly arranged around the fixed frame 1, and a filter box 41 is fixedly arranged at the other end of the spring 44. At the same time, a vibration motor 45 is fixedly arranged on both sides of the filter box 41, so that the vibration motor 45 can be activated to drive the filter box 41 to vibrate on the fixed frame 1.

[0046] Meanwhile, a flexible tube 40 is fixedly installed on the discharge pipe 30, and the other end of the flexible tube 40 is connected to the filter box 41, so that the reactants can be introduced into the filter box 41 through the flexible tube 40.

[0047] Furthermore, a filter plate 42 is inclinedly arranged inside the filter box 41. The filter plate 42 is used to intercept large crystal particles. When the reactants are introduced into the filter box 41, they will be intercepted by the filter plate 42 as they flow through it. Large crystal particles are retained on the filter plate 42, while the pure product continues to flow out through the filter plate 42. An outlet 43 is fixedly opened at the lower end of the filter box 41, so that the pure product can be exported through the outlet 43 for subsequent processing.

[0048] Meanwhile, a slag discharge port 46 is provided at the lower end of the filter plate 42 in the filter box 41. The slag discharge port 46 is used to discharge large crystal particles intercepted on the filter plate 42. When the reaction products are continuously discharged, impurities will gradually accumulate on the filter plate 42. When a certain amount is accumulated, the vibration motor 45 can be started. The vibration motor 45 transmits vibration to the filter plate 42 through the spring 44, which loosens the impurities on the filter plate 42 and gradually slides through the inclined filter plate 42 to the slag discharge port 46. Finally, the crystals are discharged from the slag discharge port 46.

[0049] During the discharge process, the reactants are first introduced into the filter box 41 through the hose 40, and the crystals are intercepted by the inclined filter plate 42. At this time, the pure product is discharged from the outlet 43 through the filter plate 42. Then, the vibration motor 45 is started to vibrate the filter plate 42 through the spring 44, causing the crystals on the surface to be discharged to the slag outlet 46, thereby achieving the effect of preventing discharge blockage.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
