Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a water-cooled reaction vessel. Background Technology

[0002] Water-cooled reactors play a crucial role in the production processes of many fields, including chemical and pharmaceutical industries. They can precisely control reaction temperatures, ensuring the stable and efficient conduct of various chemical reactions. For example, in resin synthesis reactions, a suitable reaction temperature is a key factor in ensuring product quality. Water-cooled reactors can effectively avoid side reactions caused by excessively high reaction temperatures, thereby improving product purity and yield.

[0003] Currently, water-cooled reactors are widely used. To improve their cooling efficiency, some designs place the coils inside the reactor body, such as the water-cooled reactor disclosed in Chinese Utility Model Patent (Announcement No. CN221674306U). This method of placing the coils inside the reactor body does indeed enhance heat exchange efficiency to some extent. However, with the increase in usage time, the drawbacks of this design gradually become apparent. After long-term use, the coils fixed inside the reactor body will face a series of maintenance challenges. Because the coils cannot be quickly removed from the reactor body, cleaning and maintenance are extremely inconvenient, often requiring a lot of time and manpower, and may even affect the normal operation of the entire production process due to untimely cleaning.

[0004] Meanwhile, existing reactors generally lack structures for easy cleaning of the coils. In actual production, impurities in the materials easily adhere to the coil surface. This accumulation not only forms scale, hindering heat transfer and reducing heat exchange efficiency, but also can cause coil corrosion, shortening the coil's lifespan. Once heat exchange efficiency decreases, the reactor struggles to maintain a stable reaction temperature, which not only affects product quality but may also increase energy consumption and production costs.

[0005] In summary, existing water-cooled reactors have significant shortcomings in terms of the removability and maintenance of the coils. There is an urgent need to develop a new technical solution to achieve rapid disassembly, cleaning, and maintenance of the coils, and to add a structure for simple cleaning of the coils, thereby improving the overall performance and effectiveness of the water-cooled reactors and meeting the growing demands of industrial production. Utility Model Content

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a water-cooled reactor.

[0007] A water-cooled reactor designed for this purpose includes a reactor body, a reactor cover mounted on the reactor body, a rotating shaft rotatably mounted on the reactor cover, and a water-cooling coil mounted inside the reactor body. The rotating shaft extends into the reactor body, and the water-cooling coil is connected to several lifting rods, which are connected to the reactor cover. A cleaning element is connected to the rotating shaft. When the rotating shaft rotates relative to the reactor cover, it can drive the cleaning element to rotate circumferentially and come into contact with the water-cooling coil for cleaning.

[0008] Preferably, the cleaning element includes a flexible cleaning strip connected to the rotating shaft. When the rotating shaft rotates relative to the vessel lid, it can drive the flexible cleaning strip to rotate circumferentially and contact the water-cooling coil for cleaning.

[0009] Preferably, the cleaning element includes soft bristles connected to the rotating shaft. When the rotating shaft rotates relative to the vessel lid, it can drive the soft bristles to rotate circumferentially and contact the water-cooling coil for cleaning.

[0010] Preferably, the cleaning element includes a soft cleaning strip and soft bristles disposed on the soft cleaning strip. The soft bristles are connected to the rotating shaft. When the rotating shaft rotates relative to the vessel lid, it can drive the soft cleaning strip and soft bristles to rotate circumferentially and come into contact with the water cooling coil for cleaning.

[0011] Preferably, the vessel lid is provided with a hanger, and the hanger rod is connected to the hanger by bolts.

[0012] Preferably, the water-cooled coil is fixed to the hanger rod by multiple pipe clamps or connected to the hanger rod by welding.

[0013] Preferably, the rotating shaft is provided with a plurality of stirring blades.

[0014] Preferably, the rotating shaft is provided with a connecting bracket, and the cleaning element is connected to the connecting bracket.

[0015] Preferably, the vessel lid is provided with an input connector and an output connector;

[0016] The input connector is connected to the input end of the water-cooling coil using a pipe fitting;

[0017] The output connector is connected to the output end of the water-cooling coil using a pipe fitting.

[0018] Preferably, the bottom of the vessel body is provided with a discharge port, and the vessel lid is provided with a feed port.

[0019] Compared with existing technologies, this invention connects the water-cooled coil to the reactor lid via a lifting rod, overcoming the traditional limitation of coils being fixed inside the reactor and difficult to disassemble. When the water-cooled coil requires cleaning and maintenance, opening the reactor lid allows the coil to be moved upwards and removed from the reactor, significantly shortening maintenance time and reducing maintenance difficulty and labor costs. Furthermore, the design of the rotating shaft connecting the cleaning element is a major innovation. When the rotating shaft rotates relative to the reactor lid, it drives the cleaning element to rotate circumferentially and contact the water-cooled coil for cleaning. This allows for real-time cleaning of impurities on the coil surface during reactor operation, effectively preventing heat exchange efficiency reduction caused by impurity adhesion and ensuring the water-cooled coil maintains consistently high heat exchange performance. This structural design not only improves the stability and reliability of the water-cooled reactor but also extends the coil's service life, reducing energy consumption and production costs caused by decreased heat exchange efficiency. It provides a more efficient, energy-saving, and easy-to-maintain equipment solution for production processes in the chemical and pharmaceutical industries. Attached Figure Description

[0033] See Figures 1-5A water-cooled reactor includes a reactor body 10, a reactor cover 20 disposed on the reactor body 10, a rotating shaft 30 rotatably disposed on the reactor cover 20, and a water-cooling coil 40 disposed inside the reactor body 10. The rotating shaft 30 extends into the reactor body 10. The water-cooling coil 40 is connected to a plurality of hanging rods 410, and the hanging rods 410 are connected to the reactor cover 20. The rotating shaft 30 is connected to a cleaning element 50. When the rotating shaft 30 rotates relative to the reactor cover 20, it can drive the cleaning element 50 to rotate circumferentially and come into contact with the water-cooling coil 40 for cleaning.

[0034] When it is necessary to disassemble the water-cooling coil for cleaning and maintenance, the connection between the vessel body and the vessel lid is disconnected, and then the vessel lid is opened and moved upward. During this process, the water-cooling coil can be moved upward, and the water-cooling coil can be removed from the vessel body, which greatly shortens the maintenance time and reduces the maintenance difficulty and labor costs.

[0035] During daily use, as the rotating shaft rotates, it drives the cleaning element to rotate circumferentially and contact the water-cooled coil for cleaning. This allows for real-time cleaning of impurities on the coil surface during reactor operation, effectively preventing the reduction in heat exchange efficiency caused by impurity adhesion and ensuring that the water-cooled coil maintains high-efficiency heat exchange performance. However, the cleaning effect of the cleaning element in this invention is limited; it does not provide a complete clean. Due to the rotating structure, some areas cannot be cleaned. The purpose is to minimize the impact of impurities on the heat exchange of the water-cooled coil.

[0036] See Figure 4 and Figure 5 In a first embodiment of the cleaning element 50, a flexible cleaning strip 510 is included. The flexible cleaning strip 510 is connected to the rotating shaft 30. When the rotating shaft 30 rotates relative to the vessel lid 20, it can drive the flexible cleaning strip 510 to rotate circumferentially and come into contact with the water-cooling coil 40 for cleaning. The flexible cleaning strip 510 is made of existing soft materials such as sponge strips or rubber strips. The purpose of using the flexible cleaning strip 510 is to clean the surface of the water-cooling coil 40 through friction.

[0037] See Figure 4 and Figure 5 In a second embodiment of the cleaning element 50, soft bristles 520 are included. These bristles 520 are connected to the rotating shaft 30. When the rotating shaft 30 rotates relative to the vessel lid 20, it causes the soft bristles 520 to rotate circumferentially and come into contact with the water-cooling coil 40 for cleaning. Compared to the soft cleaning strip 510, the soft bristles 520 have a larger cleaning range and are more effective at extending into the gaps between the coils for cleaning.

[0038] See Figure 4 and Figure 5The third embodiment of the cleaning element 50 includes a soft cleaning strip 510 and soft bristles 520 disposed on the soft cleaning strip 510. The soft bristles 520 are connected to the rotating shaft 30. When the rotating shaft 30 rotates relative to the vessel cover 20, it can drive the soft cleaning strip 510 and the soft bristles 520 to rotate circumferentially and come into contact with the water cooling coil 40 for cleaning.

[0039] See Figure 4 and Figure 5 The rotating shaft 30 is provided with a connecting frame 310, and the cleaning element 50 is connected to the connecting frame 310.

[0040] When the first and third embodiments of the cleaning element 50 are used, the connecting bracket 310 is provided with a slot with an opening at the top. The soft cleaning strip 510 is inserted into the slot from top to bottom, and part of the soft cleaning strip 510 is located outside the slot to fit and clean the water cooling coil 30.

[0041] When the first and second embodiments of the cleaning element 50 are used, the soft bristles 520 are fixed on the connecting frame 310.

[0042] See Figure 2 The vessel lid 20 is provided with a hanger 220, and the hanger rod 410 is connected to the hanger 220 by bolts.

[0043] In this invention, the water-cooled coil 40 is fixed to the hanger rod 410 by multiple pipe clamps or by welding. Alternatively, other existing coil fixing structures can be used, the purpose of which is simply to fix it to the hanger rod 410.

[0044] See Figure 4 and Figure 5 The rotating shaft 30 is provided with a plurality of stirring blades 300.

[0045] See Figure 3 The vessel lid 20 is provided with an input connector 230 and an output connector 240; the input connector 230 is connected to the input end of the water cooling coil 40 by means of a pipe fitting; the output connector 240 is connected to the output end of the water cooling coil 40 by means of a pipe fitting.

[0046] See Figure 1 and Figure 2 The bottom of the vessel body 10 is provided with a discharge port 100, and the vessel cover 20 is provided with a feed port 210.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
