Technical Field
[0001] This utility model relates to the field of chemical technology, and in particular to a chemical reaction vessel. Background Technology
[0002] With the continuous advancement of technological and industrial modernization, industrial production equipment is constantly being upgraded. Chemical production reactors can effectively improve the efficiency of chemical production. With the development of science and technology, chemical production reactors have developed to a great extent, and their types and quantities are increasing day by day.
[0003] In the prior art, such as Chinese patent CN221999868U, a chemical reaction vessel for chemical use is disclosed, including a support platform and a vessel body. The vessel body is fixedly connected to the upper surface of the support platform, and a bracket is fixedly connected to the upper surface of the vessel body. The bracket is fixedly connected to the upper surface of the vessel body, and a motor is fixedly connected to the surface of the bracket. A bearing is installed on the upper surface of the vessel body, and a rotating shaft is installed in the bearing. The upper end of the rotating shaft is fixedly connected to the other end of the motor output shaft. Its beneficial effect is that when using the vessel body for chemical reaction, people first control the motor to operate through the controller. The motor drives the stirring paddle to rotate, and the stirring paddle drives two sets of cleaning components to rotate. During this process, the telescopic rod and spring cooperate to push the movable plate and the hard brush, so that the hard brush always rotates in contact with the inner wall of the vessel. The hard brush can clean the sediment attached to the inner wall of the vessel in a timely manner, which facilitates the cleaning of sediment attached to the inner wall of the vessel.
[0004] In the aforementioned patent, the hard-bristled brush rotates while always adhering to the inner wall of the reactor, which can promptly clean the sediment adhering to the inner wall of the reactor. However, when adding chemical solutions, the chemical solutions are added from the top of the reactor via an addition pipe. The added chemical solutions can only contact the upper layer of the reaction stock solution, making it difficult to quickly contact all parts of the reaction stock solution, thus reducing the reaction rate. Utility Model Content
[0005] The purpose of this invention is to solve the problem in the aforementioned patent where a hard-bristled brush is always in contact with the inner wall of the reactor and rotates to clean the sediment adhering to the inner wall of the reactor in a timely manner. However, when adding chemical solutions, the chemical solutions are added from the top of the reactor and can only contact the upper layer of the reaction stock, making it difficult to quickly contact all parts of the reaction stock and thus reducing the reaction rate. Therefore, this invention proposes a chemical reaction vessel.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a chemical reaction vessel, comprising a vessel body, a cover plate fixedly connected to the top of the vessel body, a hollow tube movably passing through the top of the cover plate, a fixed frame rotatably connected to the outer surface of the hollow tube, a motor fixedly connected to the inner wall of one side of the fixed frame, a driving gear fixedly connected to the output end of the motor, threaded sleeves symmetrically rotatably connected to the inner surface of the fixed frame, reciprocating screws threadedly connected to the inner surfaces of both threaded sleeves, driven gears fixedly connected to the outer surfaces of both threaded sleeves, a transmission gear fixedly connected to the outer surface of the hollow tube, a rotary sealing joint installed at the top of the hollow tube, a flexible hose installed at the top of the rotary sealing joint, a metering cylinder fixedly connected to the end of the flexible hose away from the rotary sealing joint, and multiple drug outlets evenly opened on the outer surface of the hollow tube.
[0007] Preferably, the outer surface of the driving gear meshes with the outer surface of the transmission gear, the outer surfaces of both driven gears mesh with the outer surfaces of the driven gears, the bottoms of both reciprocating screws are fixedly connected to the top of the cover plate, and multiple stirring blades are fixedly connected to the outer surface of the hollow tube.
[0008] Preferably, the top of each of the two reciprocating lead screws is fixedly connected to a mounting bracket, and the bottom of each of the two mounting brackets is fixedly connected to the top of the cover plate.
[0009] Preferably, a rectangular block is fixedly connected to the outer surface of the hose, and the top of the rectangular block is fixedly connected to the inner bottom of the fixing frame.
[0010] Preferably, a drug extraction tube is fixedly connected to the top of the metering cylinder, a first one-way valve is installed on the outer surface of the drug extraction tube, and a second one-way valve is installed on the outer surface of the flexible tube.
[0011] Preferably, an electric actuator is fixedly connected to the inner bottom of the measuring cylinder, the driving end of the electric actuator movably penetrates the inner bottom of the measuring cylinder, and a piston is fixedly connected to the output end of the electric actuator.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, a hydraulic rod drives a piston to move, causing the extraction tube to draw a fixed amount of solution and transport it through a hose to a hollow tube. During the transport process, the motor starts, driving the drive gear and transmission gear to rotate. Under the action of the rotary sealing joint, the hollow tube and stirring blade rotate. The solution is transported to different positions inside the vessel through the outlet. Simultaneously, the transmission gear drives two driven gears to rotate synchronously, causing two threaded sleeves to rotate along the fixed frame. This causes the threaded sleeves to move up and down along the reciprocating screw, which in turn causes the fixed frame and hollow tube to move back and forth. This, in turn, causes the stirring blade to move up and down, ensuring that the added solution is fully mixed with the internal raw materials, thus increasing the reaction speed and making it highly practical.
[0014] 2. In this utility model, during the reciprocating motion of the fixing frame, the rectangular block can limit and guide the hose, avoiding unnecessary bending and twisting, thereby ensuring the smooth flow of the solution. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1, such as Figures 1-5 As shown, this utility model provides a chemical reaction vessel, including a vessel body 1. A cover plate 9 is fixedly connected to the top of the vessel body 1. A hollow tube 11 is movably passed through the top of the cover plate 9. A fixing frame 10 is rotatably connected to the outer surface of the hollow tube 11. A motor 5 is fixedly connected to the inner wall of one side of the fixing frame 10. A drive gear 18 is fixedly connected to the output end of the motor 5. Threaded sleeves 8 are symmetrically rotatably connected to the inner surface of the fixing frame 10. A reciprocating screw 6 is threadedly connected to the inner surface of each of the two threaded sleeves 8. A driven gear 7 is fixedly connected to the outer surface of each of the two threaded sleeves 8. A transmission gear 21 is fixedly connected to the outer surface of the hollow tube 11. A rotary sealing joint 20 is installed at the top of the hollow tube 11. A flexible hose 4 is installed at the top of the rotary sealing joint 20. A metering cylinder 2 is fixedly connected to the end of the flexible hose 4 away from the rotary sealing joint 20. The outer surface of the measuring cylinder 2 is uniformly provided with multiple drug outlets 12. The outer surface of the driving gear 18 meshes with the outer surface of the transmission gear 21. The outer surfaces of the two driven gears 7 mesh with the outer surfaces of the driven gears 7. The bottoms of the two reciprocating screws 6 are fixedly connected to the top of the cover plate 9. Multiple stirring blades 13 are fixedly connected to the outer surface of the hollow tube 11. Mounting brackets 14 are fixedly connected to the tops of the two reciprocating screws 6. The bottoms of the two mounting brackets 14 are fixedly connected to the top of the cover plate 9. A drug extraction tube 3 is fixedly connected to the top of the measuring cylinder 2. A first one-way valve 15 is installed on the outer surface of the drug extraction tube 3. A second one-way valve 22 is installed on the outer surface of the hose 4. An electric push rod 17 is fixedly connected to the inner bottom of the measuring cylinder 2. The driving end of the electric push rod 17 moves through the inner bottom of the measuring cylinder 2. A piston 16 is fixedly connected to the output end of the electric push rod 17.
[0024] The overall effect of Embodiment 1 is as follows: After the raw material is added to the vessel body 1 through the feed port on the cover plate 9, it is connected to the external solution tank through the extraction pipe 3. The electric actuator 17 is activated, which drives the piston 16 to move downward, generating negative pressure and thus drawing the external solution into the metering cylinder 2 through the extraction pipe 3. The amount of liquid extracted is observed through the scale on the outside of the metering cylinder 2. After extraction is completed, the electric actuator 17 is activated in reverse, which drives the piston 16 to move upward, so that the solution in the metering cylinder 2 is transported to the hollow tube 11 through the hose 4. During use, the first one-way valve 15 allows the solution in the metering cylinder 2 to be drawn into the vessel body 1 in one direction through the extraction pipe 3, and the second one-way valve 22 allows the solution in the metering cylinder 2 to be discharged in one direction through the hose 4. When the solution enters the hollow tube 11, it will be transported to the vessel body 1 through multiple outlets 12 on the outside of the hollow tube 11. During the addition of solvent, the motor 5 is started simultaneously at different locations inside the vessel, driving the drive gear 18 to rotate. This causes the transmission gear 21 to rotate synchronously. The rotation of the transmission gear 21, along with the action of the rotary sealing joint 20, causes the hollow tube 11 to rotate, making the stirring blade 13 rotate inside the vessel 1 to stir the internal materials. At the same time, the transmission gear 21 drives two driven gears 7 to rotate synchronously, causing two threaded sleeves 8 to rotate along the fixed frame 10. The rotation of the threaded sleeves 8 causes them to move up and down along the reciprocating screw 6, driving the fixed frame 10 and the hollow tube 11 to reciprocate. This up-and-down movement of the stirring blade 13 during rotation ensures that the added solution is fully mixed with the internal raw materials, improving the reaction speed and making it highly practical.
[0025] Example 2, as Figures 1-5 As shown, a rectangular block 19 is fixedly connected to the outer surface of the hose 4, and the top of the rectangular block 19 is fixedly connected to the inner bottom of the fixing frame 10.
[0026] The effect achieved by the entire embodiment 2 is that when the fixing frame 10 moves up and down, the rectangular block 19 can limit and guide the hose 4, avoiding unnecessary bending and twisting, thereby ensuring the smooth flow of the solution.
[0027] Working Principle: After the raw material is heated into the reactor body 1 through the feed inlet on the cover plate 9, it is connected to the external solution tank through the extraction pipe 3. Activating the electric actuator 17 moves the piston 16 downwards, generating negative pressure to draw the external solution into the metering cylinder 2 through the extraction pipe 3. The amount of liquid extracted is observed through the scale on the outside of the metering cylinder 2. After extraction, the electric actuator 17 is activated in reverse, moving the piston 16 upwards, allowing the solution in the metering cylinder 2 to be transported to the hollow tube 11 through the hose 4. During use, the first one-way valve 15 allows the solution in the metering cylinder 2 to be drawn out unidirectionally through the extraction pipe 3, and the second one-way valve 22 allows the solution in the metering cylinder 2 to be discharged unidirectionally through the hose 4. When the solution enters the hollow tube 11, it is transported to different positions inside the reactor body 1 through multiple outlets 12 on the outside of the hollow tube 11. Simultaneously, during the solvent addition process... The motor 5 will start synchronously, driving the drive gear 18 to rotate, which in turn drives the transmission gear 21 to rotate synchronously. Through the rotation of the transmission gear 21 and the action of the rotary sealing joint 20, the hollow tube 11 will rotate, causing the stirring blade 13 to rotate inside the vessel body 1, stirring the internal materials. At the same time, the transmission gear 21 will drive the two driven gears 7 to rotate synchronously, causing the two threaded sleeves 8 to rotate along the fixed frame 10. Through the rotation of the threaded sleeves 8, the threaded sleeves 8 will move up and down along the reciprocating screw 6, causing the fixed frame 10 and the hollow tube 11 to move back and forth. This causes the stirring blade 13 to move up and down while rotating. The rectangular block 19 can limit and guide the hose 4, avoiding unnecessary bending and twisting, so that the added solution is fully mixed with the internal raw materials, improving the reaction speed and making it highly practical.
[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
