[0001] The utility model relates to the technical field of reactors, in particular to a continuous reactor. Background Art

[0002] In chemical and industrial production, various reactions are often required, and the gas input and dispersion method during the reaction process has an important impact on the efficiency and effect of the reaction.

[0003] Traditional reactors may have problems such as uneven gas input and insufficient mixing of reaction materials, resulting in low reaction efficiency and unstable product quality.

[0004] To this end, we propose a continuous reactor. Utility Model Content

[0005] The main purpose of the present invention is to provide a continuous reactor, which can prevent problems such as uneven gas input and insufficient mixing of reaction materials, thereby improving the uniformity of gas input and the mixing degree of reaction materials, effectively improving the reaction efficiency and the stability of product quality, and can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A continuous reactor comprises a reactor body, a filtering device, and a disperser. A reaction chamber is provided inside the reactor body, an annular tube is provided at the bottom of the reaction chamber, a first gas pipe is fixedly connected to the outside of the annular tube, and an end of the first gas pipe away from the annular tube passes through the reactor body and is fixedly connected to one end of the filtering device. A first cavity, a second cavity, and a through groove are defined inside the disperser, the second cavity being located directly above the first cavity and connected via the through groove. An exhaust hole is defined on the upper portion of the outer side of the disperser, located at the position of the second cavity.

[0008] The annular tube is provided with a plurality of evenly distributed second air pipes in an annular array on the inner side away from the first air pipe, and a one-way ventilation mechanism is provided inside the second air pipe, and the one-way ventilation mechanism includes a tension spring bracket fixedly arranged on the inner wall of the second air pipe, and a one-way blocking ring is fixedly arranged on the inner side of the second air pipe near the annular tube, and a center ring hole is provided at the center position of the one-way blocking ring. A one-way blocking ball is movably provided on the end of the one-way blocking ring away from the tension spring bracket, and the diameter of the one-way blocking ball is larger than the diameter of the center ring hole. A reset holding spring is fixedly installed on the end of the tension spring bracket close to the one-way blocking ring, and the other end of the reset holding spring is fixedly connected to the one-way blocking ball, and the reset holding spring is in a stretched state. The disperser is located on the inner side of the annular tube, and the annular tube is connected to the first cavity in the disperser through the second air pipe. The top of the disperser is fixedly connected to a connecting column, and the upper outer part of the connecting column is fixedly connected to a baffle, and the diameter of the baffle is larger than the diameter of the disperser.

[0009] By adopting the above technical solution, the gas enters the first gas pipe through the filtering device and then reaches the annular pipe. When the air pressure in the annular pipe reaches a certain level, the gas overcomes the tension of the reset holding spring and pushes the one-way blocking ball, so that the gas can enter the second gas pipe through the central ring hole and finally enter the first cavity of the disperser. Since the first cavity is connected with the second cavity located above through the through groove, the gas is discharged from the exhaust hole after entering the second cavity. There are several evenly distributed second gas pipes in the annular array on the inner side of the annular pipe. The annular pipe is connected to the first cavity in the disperser through the second gas pipe. The baffle on the upper outer side of the connecting column has a diameter larger than that of the disperser, which plays a certain protective or blocking role to prevent the exhaust hole from being blocked and affecting the exhaust of the disperser.

[0010] Furthermore, a support plate is fixedly connected to the outside of the reactor body, the filter device is fixedly installed on the top of the support plate, and an air inlet is provided at one end of the filter device away from the first air pipe, and an exhaust port is provided at the upper part of the reactor body away from the air inlet.

[0011] By adopting the above technical solution, the gas enters the filter device from the air inlet for filtration, and the filtered gas enters the annular tube through the first gas pipe. After accumulating to a certain pressure in the annular tube, it overcomes the resistance of the one-way ventilation mechanism and enters the first cavity of the disperser through the second gas pipe, then enters the second cavity through the through groove, and finally is discharged from the exhaust hole to participate in the reaction, and the gas generated by the reaction is discharged from the exhaust port.

[0012] Furthermore, a screen and several guide plates arranged at equal distances are provided on the lower inner wall of the reactor body, and the guide plates are arranged perpendicular to the screen. A catalyst is provided inside the reaction chamber and above the screen.

[0013] By adopting the above technical solution, the setting of the guide plate helps to guide the exhaust gas, making the exhaust gas distribution more even and improving the reaction efficiency. The numerous small holes are evenly distributed on the screen, allowing the exhaust gas to fully contact the catalyst, thereby better promoting the reaction.

[0014] Furthermore, a driving motor is fixedly installed on the top of the reactor body, and an output shaft of the driving motor is fixedly connected to a stirring shaft.

[0015] By adopting the above technical solution, when the driving motor at the top is working, its output shaft drives the stirring shaft to rotate, thereby stirring the substances in the reactor body, making the reaction materials fully mixed, accelerating the reaction rate, and improving the uniformity and efficiency of the reaction.

[0016] Furthermore, the bottom end of the stirring shaft passes through the reactor body and the screen and is rotatably connected to the connecting column, and a plurality of evenly distributed stirring blades are fixedly connected to the outer side of the stirring shaft.

[0017] By adopting the above technical solution, when the driving motor drives the stirring shaft to rotate, the stirring blades evenly distributed on the outside of the stirring shaft rotate accordingly. The stirring blades can stir the materials at different positions in the reaction chamber to make the mixing more uniform, further improving the efficiency and effect of the reaction. The stirring shaft passes through the reactor body and the screen and is rotatably connected to the connecting column, ensuring the stability and continuity of the stirring action.

[0018] Furthermore, a feed port is provided at the top end of the reactor body, and a discharge port is provided at the bottom end of the reactor body.

[0019] By adopting the above technical solution, the material is added into the reactor body from the feed port for reaction. After the reaction is completed, the product is discharged from the discharge port at the bottom, thereby realizing the input of the catalyst and the output of the product, completing the entire continuous reaction process.

[0021] (1) The utility model provides a continuous reactor, wherein the design of the plurality of evenly distributed second gas pipes in the annular array inside the annular tube and the disperser enables the gas to be more evenly input into the reaction chamber, thereby improving the uniformity of the gas distribution and facilitating the full progress of the reaction.

[0022] (2) The utility model provides a continuous reactor with a one-way ventilation mechanism, which allows gas to pass through only when the gas pressure in the annular tube reaches a certain level, thereby achieving pressure control of the gas input and ensuring the stability and controllability of the reaction.

[0023] (3) The utility model provides a continuous reactor, wherein the diameter of the upper portion of the outer side of the connecting column is larger than that of the baffle of the disperser, which can prevent external objects from blocking the exhaust hole, thereby ensuring smooth exhaust and reducing adverse effects on the reaction.

[0032] In order to prevent problems such as uneven gas input and insufficient mixing of reaction materials, the uniformity of gas input and the mixing degree of reaction materials are improved, which effectively improves the reaction efficiency and the stability of product quality. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, a continuous reactor includes a reactor body 1, a filtering device 2 and a disperser 6. A reaction chamber 24 is provided inside the reactor body 1. An annular tube 3 is provided at the bottom of the reaction chamber 24. A first gas pipe 4 is fixedly connected to the outside of the annular tube 3, and the end of the first gas pipe 4 away from the annular tube 3 passes through the reactor body 1 and is fixedly connected to one end of the filtering device 2. A first cavity 7, a second cavity 8 and a through groove 9 are provided inside the disperser 6. The second cavity 8 is located directly above the first cavity 7 and is connected through the through groove 9. An exhaust hole 10 is provided on the upper outer portion of the disperser 6 at the position of the second cavity 8.

[0033] The inner annular array of the annular tube 3 away from the first air supply pipe 4 has several evenly distributed second air supply pipes 5, and the interior of the second air supply pipe 5 is provided with a one-way ventilation mechanism 18, and the one-way ventilation mechanism 18 includes a tension spring bracket 13 fixedly arranged on the inner wall of the second air supply pipe 5, and the second air supply pipe 5 is fixedly provided with a one-way blocking ring 14 near the inner part of the annular tube 3, and a center ring hole 15 is provided at the center position of the one-way blocking ring 14, and a one-way blocking ball 16 is movably provided at one end of the one-way blocking ring 14 away from the tension spring bracket 13, and the diameter of the one-way blocking ball 16 is large. Regarding the diameter of the center ring hole 15, a reset holding spring 17 is fixedly installed at one end of the tension spring bracket 13 close to the one-way blocking ring 14, and the other end of the reset holding spring 17 is fixedly connected to the one-way blocking ball 16. The reset holding spring 17 is in a stretched state, and the disperser 6 is located on the inner side of the annular tube 3, and the annular tube 3 is connected to the first cavity 7 in the disperser 6 through the second air supply pipe 5. The top of the disperser 6 is fixedly connected to a connecting column 11, and the upper outer part of the connecting column 11 is fixedly connected to a baffle 12, and the diameter of the baffle 12 is larger than the diameter of the disperser 6.

[0034] During use, the gas enters the first gas pipe 4 through the filter device 2 and then reaches the annular tube 3. When the air pressure in the annular tube 3 reaches a certain level, the gas overcomes the tension of the reset holding spring 17 and pushes the one-way blocking ball 16, so that the gas can enter the second gas pipe 5 through the central annular hole 15 and finally enter the first cavity 7 of the disperser 6. Since the first cavity 7 is connected with the second cavity 8 located above through the through groove 9, after the gas enters the second cavity 8, it is discharged from the exhaust hole 10. There are several evenly distributed second gas pipes 5 in the annular array inside the annular tube 3. The annular tube 3 is connected with the first cavity 7 in the disperser 6 through the second gas pipe 5. The baffle 12 on the upper outer side of the connecting column 11 has a diameter larger than the disperser 6, which plays a certain protective or blocking role to prevent the exhaust hole 10 from being blocked and affecting the exhaust of the disperser 6.

[0035] For example, Figure 1 、 Figure 2 、 Figure 3As shown, the utility model also includes that a support plate 19 is fixedly connected to the outer side of the reactor body 1, the filter device 2 is fixedly installed on the top of the support plate 19, and the filter device 2 is provided with an air inlet 20 at one end away from the first air pipe 4, and the upper part of the reactor body 1 away from the air inlet 20 is provided with an exhaust port 26.

[0036] During use, the gas enters the filter device 2 from the air inlet 20 for filtration. The filtered gas enters the annular tube 3 through the first air pipe 4. After accumulating to a certain pressure in the annular tube 3, it overcomes the resistance of the one-way ventilation mechanism 18 and enters the first cavity 7 of the disperser 6 through the second air pipe 5. Then, it enters the second cavity 8 through the through groove 9 and is finally discharged from the exhaust hole 10 to participate in the reaction. The gas generated by the reaction is discharged from the exhaust port 26.

[0037] For example, Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention also includes that a screen 29 and several guide plates 30 are arranged at equal distances on the lower part of the inner wall of the reactor body 1, and the guide plates 30 are arranged vertically to the screen 29. A catalyst 25 is provided inside the reaction chamber 24 and on the upper part of the screen 29.

[0038] When in use, the setting of the guide plate 30 helps to guide the exhaust gas, making the exhaust gas more evenly distributed and improving the reaction efficiency. The numerous small holes evenly distributed on the screen 29 allow the exhaust gas to fully contact the catalyst 25, thereby better promoting the reaction.

[0039] For example, Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention further comprises: a driving motor 21 is fixedly mounted on the top of the reactor body 1 , and an output shaft of the driving motor 21 is fixedly connected to a stirring shaft 22 .

[0040] When in use, when the driving motor 21 at the top is working, its output shaft drives the stirring shaft 22 to rotate, thereby stirring the substances in the reactor body, so that the reaction materials are fully mixed, the reaction rate is accelerated, and the uniformity and efficiency of the reaction are improved.

[0041] For example, Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention further includes that the bottom end of the stirring shaft 22 passes through the reactor body 1 and the screen 29 and is rotatably connected to the connecting column 11 , and a plurality of evenly distributed stirring blades 23 are fixedly connected to the outside of the stirring shaft 22 .

[0042] During use, when the driving motor 21 drives the stirring shaft 22 to rotate, the stirring blades 23 evenly distributed on the outside of the stirring shaft 22 rotate accordingly. The stirring blades 23 can stir the materials at different positions in the reaction chamber to make the mixing more uniform, further improving the efficiency and effect of the reaction. The stirring shaft 22 passes through the reactor body 1 and the screen 29 and is rotatably connected to the connecting column 11, ensuring the stability and continuity of the stirring action.

[0043] For example, Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention further includes that a feed port 27 is provided at the top end of the reactor body 1 , and a discharge port 28 is provided at the bottom end of the reactor body 1 .

[0044] During use, the material is added into the reactor body 1 from the feed port 27 for reaction. After the reaction is completed, the product is discharged from the discharge port 28 at the bottom, thereby realizing the input of the catalyst 25 and the output of the product, completing the entire continuous reaction process.

[0045] It should be noted that the utility model is a continuous reactor. The feed port 27 is opened, and the catalyst 25 to be reacted is added to the reactor body 1. The air inlet 20 is opened to allow the gas to enter the filter device 2 for filtration. The filtered gas enters the annular tube 3 through the first air pipe 4. When the air pressure in the annular tube 3 reaches a certain level, the gas overcomes the resistance of the one-way ventilation mechanism 18 and passes through the central annular hole 15 and the second air pipe 5 in turn into the first cavity 7, the through groove 9 and the second cavity 8 of the disperser 6, and is finally discharged from the exhaust port 10 to participate in the reaction. At the same time, the drive motor 21 is started to drive the stirring shaft 22 and the stirring blade 23 to rotate, and the catalyst 25 and the exhaust gas are stirred and mixed. The reaction is carried out under the action of the stirring catalyst 25 and the exhaust gas. After the reaction is completed, the exhaust gas is discharged from the exhaust port 26.
