Description

Technical Field

[0001] This utility model relates to the field of heating reactor technology, specifically to a multi-layer heating reactor based on uniform gas distribution. Background Technology

[0002] A heated reactor is a device used to carry out chemical reactions. It provides the necessary temperature conditions for the reaction through heating, thus promoting the reaction process. It can also be equipped with various devices to control reaction parameters, such as temperature and material flow rate, to achieve precise control of the reaction process.

[0003] Existing multi-layer heating reactors typically use a single stirring shaft to agitate materials, which is inconvenient for efficient agitation using multiple shafts and also makes it difficult to achieve uniform aeration inside the reactor. This results in low reaction efficiency within the reactor and reduces its practicality. Therefore, we propose a multi-layer heating reactor based on uniform gas distribution to address the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer heating reactor based on uniform gas distribution, in order to solve the problems mentioned in the background art, such as the inconvenience of using multiple stirring shafts to efficiently stir materials and the inconvenience of uniformly ventilating the interior of the heating reactor, resulting in low reaction efficiency of materials inside the heating reactor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer heating reactor based on uniform gas distribution, comprising a heating vessel, a support leg installed at the bottom of the heating vessel, a heating wire installed inside the heating vessel, a feed inlet installed on one side of the top of the heating vessel, a discharge outlet installed at the middle position of the bottom of the heating vessel, an upper jacket installed above the outer wall of the heating vessel, a middle jacket installed at the middle position of the outer wall of the heating vessel, a lower jacket installed below the outer wall of the heating vessel, a feeding port installed at one end of the upper, middle, and lower jackets, a discharge port installed at the other end of the upper, middle, and lower jackets, a stirring mechanism installed inside the heating vessel, and a pressure relief mechanism installed above one side of the heating vessel;

[0006] The stirring mechanism includes a servo motor, a rotating shaft, a slant propeller, a turbine propeller, and a propeller. The servo motor is installed at the top of the heating vessel, the rotating shaft is installed inside the heating vessel, one end of the rotating shaft is rotatably connected to an external air pump via a pipe, the output end of the servo motor is connected to one end of the rotating shaft, a slant propeller is installed above the outer wall of the rotating shaft, a turbine propeller is installed at the middle position of the outer wall of the rotating shaft, and a propeller propeller is installed below the outer wall of the rotating shaft.

[0007] Preferably, the rotating shaft is hollow, and an air vent is provided on the outer wall of the rotating shaft, which can be used to spray air into the interior of the heating vessel.

[0008] Preferably, connecting rods are installed at both ends of the outer side wall of the rotating shaft, and a scraper is installed at one end of the connecting rod.

[0009] Preferably, two scrapers are provided inside the heating vessel, and the two scrapers are symmetrically distributed about the central axis of the heating vessel.

[0010] Preferably, the pressure relief mechanism includes an installation cavity, a pressure relief port, a piston, a fixed cavity, a telescopic spring, a damper, a transmission rod, a limiting groove, and a limiting block. The installation cavity is installed above one side of the heating vessel. A pressure relief port is installed above the installation cavity. A piston is installed at one end inside the installation cavity. A fixed cavity is installed on one side inside the installation cavity. A damper is installed at the middle position on one side inside the fixed cavity. Telescopic springs are installed above and below one side inside the fixed cavity. A transmission rod is installed at one end of the telescopic spring and the damper. One end of the transmission rod is connected to one end of the piston.

[0011] Preferably, the cross-section of the limiting groove is larger than the cross-section of the limiting block, and the limiting groove and the limiting block form a sliding structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By incorporating a stirring mechanism inside the heating vessel, the materials inside can be uniformly mixed through the coordinated operation of the servo motor, rotating shaft, inclined blade, turbine blade, spiral propeller, vent, connecting rod, and scraper. The vent design allows gas to be released through the rotating shaft and broken into small bubbles by the inclined blade, turbine blade, and spiral propeller, improving gas-liquid mass transfer efficiency and ensuring more uniform gas distribution within the heating vessel. The spiral propeller, located at the bottom of the mixing tank, primarily pushes the material upwards, preventing accumulation and promoting overall material circulation. The turbine blade, installed in the middle of the stirring shaft, generates radial and tangential mixing forces, dispersing the material and enhancing collision and mixing. The inclined blade, installed in the upper layer of the mixing tank, stirs and disperses the material in the upper layer while guiding it downwards, creating a circulation with the bottom and middle layers.

[0014] 2. By installing a pressure relief mechanism on the upper side of the heating vessel, the internal pressure of the heating vessel can be automatically relieved to a certain extent through the cooperation of the installation cavity, pressure relief port, piston, fixed cavity, telescopic spring, damper, transmission rod, limiting groove and limiting block of the pressure relief mechanism, making the heating vessel safer to use and thus greatly improving the safety of the reactor during use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-4A multi-layer heating reactor based on uniform gas distribution includes a heating vessel 1, a support leg 2 installed at the bottom of the heating vessel 1, an electric heating wire installed inside the heating vessel 1, a feed inlet 3 installed on one side of the top of the heating vessel 1, a discharge outlet 4 installed at the middle position of the bottom of the heating vessel 1, an upper jacket 5 installed above the outer wall of the heating vessel 1, a middle jacket 6 installed at the middle position of the outer wall of the heating vessel 1, a lower jacket 7 installed below the outer wall of the heating vessel 1, a feeding port 8 installed at one end of the upper jacket 5, middle jacket 6, and lower jacket 7, and a discharge port 9 installed at the other end of the upper jacket 5, middle jacket 6, and lower jacket 7, a stirring mechanism installed inside the heating vessel 1, and a pressure relief mechanism installed above one side of the heating vessel 1.

[0024] The stirring mechanism includes a servo motor 10, a rotating shaft 11, a slant propeller 12, a turbine propeller 13, and a helical propeller 14. The servo motor 10 is mounted at the top of the heating vessel 1, and the rotating shaft 11 is installed inside the heating vessel 1. One end of the rotating shaft 11 is connected to an external air pump via a pipe. The output end of the servo motor 10 is connected to one end of the rotating shaft 11. The slant propeller 12 is mounted above the outer wall of the rotating shaft 11, the turbine propeller 13 is mounted at the middle position of the outer wall of the rotating shaft 11, and the helical propeller 14 is mounted below the outer wall of the rotating shaft 11. In use, the servo motor 10 is started to drive the rotating shaft 11 to rotate, which in turn drives the slant propeller 12, the turbine propeller 13, and the helical propeller 14 to rotate, thus uniformly stirring the material. The helical propeller 14 is located at the bottom of the stirring tank. The main function of the mixing tank is to push the material at the bottom upwards, preventing it from accumulating and promoting overall material circulation. The propeller 14 generates strong axial thrust, causing the material to flow vertically within the tank. The turbine 13, installed in the middle of the mixing shaft, is mainly responsible for generating radial and tangential mixing forces, dispersing the material in all directions, and enhancing the collision and mixing effect between materials. The high-speed rotation of the turbine 13 can form a strong vortex, allowing the material to be fully mixed horizontally. The inclined blade 12, installed in the upper layer of the mixing tank, stirs and disperses the material in the upper layer, while guiding it downwards to form a circulation with the material in the bottom and middle layers. The inclined blade 12 effectively prevents the material from forming a static layer on the surface, ensuring uniform mixing of the material throughout the tank.

[0025] The rotating shaft 11 is hollow, and an air outlet 15 is provided on the outer wall of the rotating shaft 11. The air outlet 15 can spray gas into the interior of the heating vessel 1. During use, the design of the air outlet 15 allows the gas to be released through the interior of the rotating shaft 11 and broken into small bubbles by the inclined propeller 12, the turbine propeller 13 and the propeller propeller 14, thereby improving the gas-liquid mass transfer efficiency and making the gas more evenly distributed inside the heating vessel 1.

[0026] Connecting rods 16 are installed at both ends of the outer wall of the rotating shaft 11. A scraper 17 is installed at one end of the connecting rod 16. Two scrapers 17 are arranged inside the heating vessel 1. The two scrapers 17 are symmetrically distributed about the central axis of the heating vessel 1. In use, the rotating shaft 11 drives the connecting rod 16 to rotate. The connecting rod 16 drives the scraper 17 to rotate on the inner wall of the heating vessel 1, scraping off the material attached to the inner wall, so that the material is not easily wasted during the reaction.

[0027] Example 2

[0028] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 5 A multi-layer heating reactor based on uniform gas distribution includes a heating vessel 1, a support leg 2 installed at the bottom of the heating vessel 1, an electric heating wire installed inside the heating vessel 1, a feed inlet 3 installed on one side of the top of the heating vessel 1, a discharge outlet 4 installed at the middle position of the bottom of the heating vessel 1, an upper jacket 5 installed above the outer wall of the heating vessel 1, a middle jacket 6 installed at the middle position of the outer wall of the heating vessel 1, a lower jacket 7 installed below the outer wall of the heating vessel 1, a feeding port 8 installed at one end of the upper jacket 5, middle jacket 6, and lower jacket 7, and a discharge port 9 installed at the other end of the upper jacket 5, middle jacket 6, and lower jacket 7, a stirring mechanism installed inside the heating vessel 1, and a pressure relief mechanism installed above one side of the heating vessel 1.

[0029] The stirring mechanism includes a servo motor 10, a rotating shaft 11, a slant propeller 12, a turbine propeller 13, and a helical propeller 14. The servo motor 10 is mounted at the top of the heating vessel 1, and the rotating shaft 11 is installed inside the heating vessel 1. One end of the rotating shaft 11 is connected to an external air pump via a pipe. The output end of the servo motor 10 is connected to one end of the rotating shaft 11. The slant propeller 12 is mounted above the outer wall of the rotating shaft 11, the turbine propeller 13 is mounted at the middle position of the outer wall of the rotating shaft 11, and the helical propeller 14 is mounted below the outer wall of the rotating shaft 11. In use, the servo motor 10 is started to drive the rotating shaft 11 to rotate, which in turn drives the slant propeller 12, the turbine propeller 13, and the helical propeller 14 to rotate, thus uniformly stirring the material. The helical propeller 14 is located at the bottom of the stirring tank. The main function of the mixing tank is to push the material at the bottom upwards, preventing it from accumulating and promoting overall material circulation. The propeller 14 generates strong axial thrust, causing the material to flow vertically within the tank. The turbine 13, installed in the middle of the mixing shaft, is mainly responsible for generating radial and tangential mixing forces, dispersing the material in all directions, and enhancing the collision and mixing effect between materials. The high-speed rotation of the turbine 13 can form a strong vortex, allowing the material to be fully mixed horizontally. The inclined blade 12, installed in the upper layer of the mixing tank, stirs and disperses the material in the upper layer, while guiding it downwards to form a circulation with the material in the bottom and middle layers. The inclined blade 12 effectively prevents the material from forming a static layer on the surface, ensuring uniform mixing of the material throughout the tank.

[0030] The rotating shaft 11 is hollow, and an air outlet 15 is provided on the outer wall of the rotating shaft 11. The air outlet 15 can spray gas into the interior of the heating vessel 1. During use, the design of the air outlet 15 allows the gas to be released through the interior of the rotating shaft 11 and broken into small bubbles by the inclined propeller 12, the turbine propeller 13 and the propeller propeller 14, thereby improving the gas-liquid mass transfer efficiency and making the gas more evenly distributed inside the heating vessel 1.

[0031] Connecting rods 16 are installed at both ends of the outer wall of the rotating shaft 11. A scraper 17 is installed at one end of the connecting rod 16. Two scrapers 17 are arranged inside the heating vessel 1. The two scrapers 17 are symmetrically distributed about the central axis of the heating vessel 1. In use, the rotating shaft 11 drives the connecting rod 16 to rotate. The connecting rod 16 drives the scraper 17 to rotate on the inner wall of the heating vessel 1, scraping off the material attached to the inner wall, so that the material is not easily wasted during the reaction.

[0032] The pressure relief mechanism includes a mounting cavity 18, a pressure relief port 19, a piston 20, a fixed cavity 21, a telescopic spring 22, a damper 23, a transmission rod 24, a limiting groove 25, and a limiting block 26. The mounting cavity 18 is installed above one side of the heating vessel 1. The pressure relief port 19 is installed above the mounting cavity 18. The piston 20 is installed at one end inside the mounting cavity 18. The fixed cavity 21 is installed on one side inside the mounting cavity 18. The damper 23 is installed at the middle position on one side inside the fixed cavity 21. The telescopic spring 22 is installed above and below one side inside the fixed cavity 21. The transmission rod 24 is installed at one end of the telescopic spring 22 and the damper 23. One end of the transmission rod 24 is connected to one end of the piston 20. The fixed cavity... A limiting groove 25 is provided at the bottom inside the 21. A limiting block 26 is provided inside the limiting groove 25. The top end of the limiting block 26 is connected to the bottom end of the transmission rod 24. When the pressure inside the heating vessel 1 is high, the air pressure pushes the piston 20, causing the piston 20 to move into the mounting cavity 18, thus allowing the gas to be discharged from the pressure relief port 19. When the air pressure is balanced, the telescopic spring 22 is driven by the elastic force. Under the limitation of the limiting groove 25 and the limiting block 26, the transmission rod 24 is driven to move by the cooperation of the fixed cavity 21, which in turn drives the piston 20 to move. The piston 20 blocks the pressure relief port 19, completing the automatic pressure relief of the heating vessel 1, making the heating vessel 1 safer to use, thereby greatly improving the safety of the reactor during use.

[0033] The cross-section of the limiting groove 25 is larger than the cross-section of the limiting block 26. The limiting groove 25 and the limiting block 26 form a sliding structure. In use, the mutual cooperation between the limiting groove 25 and the limiting block 26 can limit the movement of the transmission rod 24, making the transmission rod 24 more stable when moving.

[0034] Working principle: The operator first pours the material into the heating vessel 1 through the feed inlet 3, then activates the heating wire inside the vessel 1 to heat the material. Simultaneously, the servo motor 10 drives the rotating shaft 11 to rotate, which in turn drives the inclined propeller 12, turbine propeller 13, and spiral propeller 14 to rotate, uniformly stirring the material. At the same time, the connecting rod 16 drives the scraper 17 to rotate on the inner wall of the heating vessel 1, scraping off the material adhering to the inner wall, preventing material waste during the reaction. Gas is then introduced into the rotating shaft 11 via an external air pump and hose, and sprayed out through the air outlet 15, ensuring a more uniform gas distribution inside the heating vessel 1, thus improving the reaction effect of the material. Different heat transfer media are added to the upper jacket 5, middle jacket 6 and lower jacket 7 through the feeding port 8, so that the heating vessel 1 can perform segmented and precise temperature control when heating and reacting materials, resulting in better reaction effect. When the internal pressure of the heating vessel 1 is high, the air pressure pushes the piston 20, causing the piston 20 to move into the mounting cavity 18, thus causing the gas to be discharged from the pressure relief port 19. When the air pressure is equalized, the telescopic spring 22 is driven by the elastic force, and under the limit of the limiting groove 25 and the limiting block 26, it drives the transmission rod 24 to move with the cooperation of the fixed cavity 21, which in turn drives the piston 20 to move. The piston 20 blocks the pressure relief port 19, completing the automatic pressure relief of the heating vessel 1.
