Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a reactor that prevents materials from adhering to inner walls. Background Art

[0002] Reactors are widely used in chemistry, petrochemicals, medicine, food, and various other scientific research fields, primarily for conducting chemical reactions involving various substances. Reactors range in capacity from a few liters to several thousand liters, and can be made of materials such as stainless steel, enamel, and steel linings. As indispensable equipment in the chemical and other related industries, reactors are widely used in experimental research and industrial production. However, during use, reacting materials can easily adhere to the reactor's inner walls, resulting in material waste and hindering the reactor's usability. Therefore, a reactor design that prevents material adhesion is needed.

[0003] A reactor for preventing material adhesion is disclosed in publication number CN220590022U. Although the utility model uses an anti-sticking mechanism to scrape the inner wall of the reactor body through a scraper when the material reacts inside the reactor body, the material cannot adhere to the inner wall of the reactor body, and the material at the discharge pipe is stirred by a fixed rod to prevent the material from clogging the discharge pipe and avoiding material waste. The inside of the reactor body can be cleaned by removing the sealing cover, which facilitates the next use of the reactor body and improves the utilization efficiency of the reactor body.

[0004] However, during the stirring process, the scraper of this utility model will continuously rub against the inner wall of the reactor. The continuous scratching may cause physical damage to the inner wall of the reactor, such as scratches and deformation. These damages may become the starting point of stress corrosion. Severe physical damage may lead to structural failure of the reactor and increase the risk of production safety. Utility Model Content

[0032] Example 1

[0033] Reference Figure 1-5 , which is the first embodiment of the present utility model, provides a reactor for preventing materials from adhering to the inner wall, and the structure includes:

[0034] The main unit 100 includes a reactor body 101. The inner wall of the reactor body 101 is provided with a ceramic coating. The edge of the reactor body 101 is fixedly connected to a support frame 102. The surface of the reactor body 101 is provided with an inlet 103. During use, materials are injected into the reactor body 101 through the inlet 103 for reaction. The wear resistance and corrosion resistance of the ceramic coating effectively prevent the materials from adhering to the reactor body 101. The reacted materials are discharged through the discharge port 1011.

[0035] The control unit 200 includes a servo motor 201. The output end of the servo motor 201 is connected to a first gear 202. A chain 203 is meshed with the surface of the first gear 202. A second gear 204 is meshed with the surface of the chain 203. During use, the servo motor 201 is started to drive the first gear 202 to rotate. The meshing of the chain 203 drives the second gear 204 to rotate synchronously. The second gear 204 drives the bottom telescopic rod 2041 to rotate.

[0036] The stirring assembly 300 includes an inner tube 301, which is fixedly connected to the center of the top of the reactor body 101. The surface of the inner tube 301 is provided with an external thread groove, and the outer tube 302 is connected to the outer thread groove through a thread. The bottom of the outer tube 302 is fixedly connected to a rectangular block 303, and the surface of the outer tube 302 is fixedly connected to a stirring rod 304. During use, the telescopic rod 2041 drives the rectangular block 303 to rotate, thereby driving the outer tube 302 to rotate. Due to the threaded connection between the internal thread groove of the central tube 3021 and the external thread groove on the inner tube 301, the central tube 3021 and the outer tube 302 move downward. When the servo motor 201 rotates in the opposite direction, the outer tube 302 moves upward. The rotation of the outer tube 302 drives the stirring rod 304 to rotate at the same time, stirring the material and accelerating the reaction of the material.

[0037] The backflow prevention assembly 400 includes a fixing plate 401, which is fixedly connected to the inner wall of the tube perforation opened inside the stirring rod 304. A spring 402 is fixedly connected to one side of the fixing plate 401, and a baffle 403 is fixedly connected to one end of the spring 402. During use, after the reactor body 101 is used, the top of the inner tube 301 is connected to the water pump and the external water source, and high-pressure water is delivered to the inner tube 301 and the outer tube 302. The clean water flushes the baffle 403 to stretch the spring 402, and the water is sprayed through the through hole of the stirring rod 304 to flush the inner wall of the reactor body 101 and wash off the adhered matter. When the water is stopped from being poured into the inner tube 301, the spring 402 is not forced to contract and drives the baffle 403 to rebound and block the through hole, thereby preventing the material from entering the stirring rod 304 during the reaction.

[0038] Furthermore, a discharge port 1011 is provided at the bottom of the reactor body 101 , and a valve 1012 is provided on the surface of the discharge port 1011 . When the valve 1012 is opened, the material or water in the reactor body 101 can be discharged through the discharge port 1011 .

[0039] Furthermore, a through hole is opened in the center of the second gear 204, and the inner tube 301 is inserted into the through hole. Through the setting of the through hole, the second gear 204 can rotate on the surface of the inner tube 301 without affecting the fixation of the inner tube 301.

[0040] Furthermore, a telescopic rod 2041 is fixedly connected to the bottom of the second gear 204 , and the bottom end of the telescopic rod 2041 is fixedly connected to the rectangular block 303 . The telescopic rod 2041 drives the rectangular block 303 to rotate, thereby driving the outer tube 302 to rotate.

[0041] Furthermore, a central tube 3021 is provided at the center of the outer tube 302 , and an inner thread groove is provided on the inner wall of the central tube 3021 . The outer tube 302 can be moved up and down by threaded connection between the inner thread groove and the outer thread groove.

[0042] Furthermore, a groove is formed on the inner wall of one end of the through hole, and the blocking piece 403 is movably connected to the groove. The blocking piece 403 abuts against the groove, thereby preventing the material from entering the outer tube 302 through the through hole during the mixing process.

[0043] During use, the material is first injected into the reactor body 101 through the feed port 103 for reaction. The wear resistance and corrosion resistance of the ceramic coating effectively prevent the material from adhering. Then, the servo motor 201 is started to drive the first gear 202 to rotate. The chain 203 is engaged, which drives the second gear 204 to rotate synchronously. The second gear 204 drives the telescopic rod 2041 at the bottom to rotate.

[0044] Then, the telescopic rod 2041 drives the rectangular block 303 to rotate, thereby driving the outer tube 302 to rotate. Due to the threaded connection between the internal thread groove of the central tube 3021 and the external thread groove on the inner tube 301, the central tube 3021 and the outer tube 302 move downward. When the servo motor 201 rotates in the opposite direction, the outer tube 302 moves upward. The rotation of the outer tube 302 drives the stirring rod 304 to rotate, stirring the material and accelerating the reaction of the material. The reacted material is discharged through the discharge port 1011.

[0045] Finally, after the reactor body 101 is used, the top of the inner tube 301 is connected to a water pump and an external water source, and high-pressure water is delivered to the inner tube 301 and the outer tube 302. The clean water flushes the baffle 403 to stretch the spring 402, and is sprayed through the through hole of the stirring rod 304 to wash the inner wall of the reactor body 101 and wash away the adhered matter. When the water supply to the inner tube 301 is stopped, the spring 402 is not forced to contract and drives the baffle 403 to rebound and block the through hole, thereby preventing the material from entering the stirring rod 304 during the reaction.

[0046] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
