Description

Technical Field

[0001] This invention belongs to the field of liquid reactors, specifically an automated liquid reactor. Background Technology

[0002] Liquid reactors are commonly used devices for stirring and reacting liquid materials, and are frequently used in chemical synthesis operations. However, current liquid reactors still require manual control of the feeding and reaction process. Manual control not only makes it difficult to accurately control the feed ratio, but also easily leads to fluctuations in reaction conditions due to operational errors, affecting the quality and yield of the final product. Furthermore, traditional reactors often use unidirectional stirring, resulting in insufficient mixing of materials at different depths within the reactor. Materials near the reactor walls and bottom often fail to fully participate in the reaction, impacting reaction efficiency. Summary of the Invention

[0003] This invention provides an automated liquid reactor to overcome the deficiencies in the prior art.

[0004] This invention is achieved through the following technical solution: An automated liquid reaction vessel includes a vessel body. The top of the vessel body is connected to several sample inlet tubes, each equipped with a solenoid valve and a flow meter. A motor is vertically positioned at the center of the top of the vessel body. The motor's output shaft passes through the center of the top of the vessel body and is fixedly connected to the top of a vertically positioned first rotating rod. The first rotating rod has an array of first stirring blades arranged from top to bottom. The motor's output shaft is fixedly connected to the inner ring of a first bearing, and the outer ring of the first bearing is fixedly connected to the center of the top of the vessel body. The bottom of the first rotating rod is connected to the top of a reverse rotation mechanism, and the bottom of the reverse rotation mechanism is connected to the top of a vertically positioned second rotating rod. The reverse rotation mechanism can drive the second rotating rod to rotate in the opposite direction to the first rotating rod. The second rotating rod has an array of second stirring blades arranged from top to bottom. The bottom of the second rotating rod is fixedly connected to the inner ring of a second bearing, and the outer ring of the second bearing is fixedly connected to the center of the bottom of the vessel body. A temperature control mechanism is installed inside the vessel body. The bottom of the vessel body is connected to a discharge pipe, which is equipped with a discharge solenoid valve and a discharge pump.

[0005] In the automated liquid reactor described above, the size of the first stirring blade on the first rotating rod increases sequentially from top to bottom, and the size of the second stirring blade on the second rotating rod decreases sequentially from top to bottom.

[0006] An automated liquid reactor as described above includes a reversible rotation mechanism comprising a housing. The bottom end of a first rotating rod passes through the center of the top of the housing and is fixedly connected to the center of the top of a horizontally positioned first bevel gear. The first rotating rod is fixedly connected to the inner ring of a third bearing, and the outer ring of the third bearing is fixedly connected to the center of the top of the housing. The first bevel gear meshes with the top of a vertically positioned second bevel gear. One side of the second bevel gear is fixedly connected to the outer ring of a fourth bearing. The inner ring of the fourth bearing is fixedly connected to one end of a crossbar, and the other end of the crossbar is fixedly connected to the inner wall of the housing. A third bevel gear is positioned directly below the first bevel gear and meshes with the bottom of the second bevel gear. The top of the second rotating rod passes through the center of the bottom of the housing and is fixedly connected to the center of the bottom of the third bevel gear. The second rotating rod is fixedly connected to the inner ring of a fifth bearing, and the outer ring of the fifth bearing is fixedly connected to the center of the bottom of the housing.

[0007] As described above, in an automated liquid reactor, one end of a horizontally arranged fixing rod is fixedly connected to each side of the container body, and the other end of the fixing rod is fixedly connected to the inner wall of the reactor body.

[0008] As described above, in an automated liquid reactor, the temperature control mechanism includes several temperature sensors spaced at fixed intervals from top to bottom. A heat exchange chamber is located inside the reactor's inner wall. The bottom of the heat exchange chamber is connected to a steam inlet pipe and a cooling medium inlet pipe. A steam flow adjustment solenoid valve is installed on the steam inlet pipe, and a cooling medium flow adjustment solenoid valve is installed on the cooling medium inlet pipe. The top of the heat exchange chamber is connected to a steam outlet pipe and a cooling medium outlet pipe. A steam outlet solenoid valve is installed on the steam outlet pipe, and a cooling medium outlet solenoid valve is installed on the cooling medium outlet pipe.

[0009] As described above, in an automated liquid reaction vessel, the top of the vessel body is connected to the top of a storage device via a pipeline, and a safety valve is installed on the pipeline connecting the top of the vessel body and the top of the storage device.

[0010] As described above, in an automated liquid reactor, the bottom of the storage tank is connected to the top of the reactor body via a pipeline, and a recovery solenoid valve and a recovery pump are installed on the pipeline connecting the reactor body and the bottom of the storage tank.

[0011] The advantages of this invention are as follows: Firstly, by using an injection tube, an injection solenoid valve, and a flow meter, this invention enables automatic and precise control of the feed rate for different raw materials, eliminating the need for manual on-site adjustment and effectively avoiding human error, thus ensuring accurate feed ratios. Secondly, the reverse rotation mechanism drives the first and second rotating rods to rotate in opposite directions, causing the first and second stirring blades to rotate in opposite directions. This creates a more complex and turbulent liquid flow within the reactor, thoroughly mixing materials at different depths and positions, avoiding insufficient mixing of materials near the reactor walls and bottom, effectively improving the uniformity of material mixing, ensuring a complete reaction, and increasing reaction efficiency and product yield. Thirdly, the temperature control mechanism in this invention can monitor the temperature at different locations within the reactor in real time, selecting the appropriate temperature adjustment level based on the acquired temperature, thereby precisely controlling the reaction temperature within the reactor and ensuring the reaction proceeds within the specified temperature range.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] like Figure 1 and Figure 2 As shown, an automated liquid reaction vessel includes a vessel body 1. The top of the vessel body 1 is connected to several sample inlet pipes 2. A sample inlet solenoid valve 3 and a flow meter 4 are installed on each sample inlet pipe 2. A motor 5 is vertically positioned at the center of the top of the vessel body 1. The output shaft of the motor 5 passes through the center of the top of the vessel body 1 and is fixedly connected to the top of a vertically positioned first rotating rod 6. An array of first stirring blades 7 are arranged from top to bottom on the first rotating rod 6. The output shaft of the motor 5 is fixedly connected to the inner ring of a first bearing 8. The outer ring of the first bearing 8 is fixedly connected to the center of the top of the vessel body 1. The bottom of the first rotating rod 6... The top of the reverse rotation mechanism is connected to the top of the vertically arranged second rotating rod 9. The reverse rotation mechanism can drive the second rotating rod 9 to rotate in the opposite direction to the first rotating rod 6. The second rotating rod 9 is provided with an array of second stirring blades 10 from top to bottom. The bottom of the second rotating rod 9 is fixedly connected to the inner ring of the second bearing 11. The outer ring of the second bearing 11 is fixedly connected to the center of the bottom of the vessel body 1. The vessel body 1 is provided with a temperature control mechanism. The bottom of the vessel body 1 is connected to the discharge pipe 12. The discharge pipe 12 is provided with a discharge solenoid valve 13 and a discharge pump 14. In this invention... During use, according to the preset raw material feeding ratio, the injection solenoid valves 3 on different injection tubes 2 are opened respectively. The flow meter 4 monitors the feed flow rate of the corresponding injection tube 2 in real time. When the feed amount reaches the preset value, the corresponding injection solenoid valve 3 automatically closes, completing precise automatic feeding without manual adjustment and control, and the injection amount control accuracy is high. After feeding is completed, the motor 5 is started. The motor 5 drives the first rotating rod 6 and the first stirring blade 7 to rotate. The first rotating rod 6 drives the second rotating rod 9 and the second stirring blade 10 to rotate in opposite directions through the reverse rotation mechanism, forming a turbulent liquid flow with alternating directions inside the vessel body 1. This drives the materials at different depths inside the vessel body 1, near the vessel wall and the bottom of the vessel body 1 to fully turn and mix, avoiding the problem of uneven material mixing and ensuring that the reaction proceeds fully. During the reaction, the temperature control mechanism can monitor the temperature at different positions inside the vessel in real time, select the degree of temperature adjustment based on the acquired temperature, and thus precisely control the reaction temperature inside the vessel to ensure that the reaction proceeds within the specified temperature range.

[0017] Specifically, in this embodiment, the size of the first stirring blade 7 on the first rotating rod 6 increases sequentially from top to bottom, while the size of the second stirring blade 10 on the second rotating rod 9 decreases sequentially from top to bottom. This arrangement of the first stirring blade 7 and the second stirring blade 10 in this invention enables the liquid at the top and bottom of the vessel 1 to circulate towards the center, further enhancing the mixing effect of materials at different depths, preventing material stratification at the top and bottom of the vessel, and improving the overall reaction efficiency. After the reaction is complete, the discharge solenoid valve 13 is opened, and the discharge pump 14 is started, allowing the reacted material to be discharged from the vessel 1 through the discharge pipe 12, thus completing the entire reaction process.

[0018] Specifically, the reverse rotation mechanism described in this embodiment includes a housing 15. The bottom end of the first rotating rod 6 passes through the center of the top of the housing 15 and is fixedly connected to the center of the top of the horizontally arranged first bevel gear 16. The first rotating rod 6 is fixedly connected to the inner ring of the third bearing 17, and the outer ring of the third bearing 17 is fixedly connected to the center of the top of the housing 15. The first bevel gear 16 meshes with the top of the vertically arranged second bevel gear 18. One side of the second bevel gear 18 is fixedly connected to the outer ring of the fourth bearing 19. The inner ring of 19 is fixedly connected to one end of the crossbar 20, and the other end of the crossbar 20 is fixedly connected to the inner wall of the box 15. A third bevel gear 21 is provided directly below the first bevel gear 16. The third bevel gear 21 meshes with the bottom of the second bevel gear 18. The top of the second rotating rod 9 passes through the center of the bottom of the box 15 and is fixedly connected to the center of the bottom of the third bevel gear 21. The second rotating rod 9 is fixedly connected to the inner ring of the fifth bearing 22, and the outer ring of the fifth bearing 22 is fixedly connected to the center of the bottom of the box 15. In this invention, when the first rotating rod 6 rotates with the output shaft of the motor 5, the first rotating rod 6 drives the first bevel gear 16 to rotate synchronously. The first bevel gear 16 meshes with and drives the second bevel gear 18 to rotate around the crossbar 20. The bottom of the second bevel gear 18 meshes with and drives the third bevel gear 21 to rotate. The rotation direction of the third bevel gear 21 is opposite to that of the first bevel gear 16. Therefore, the second rotating rod 9 rotates in the opposite direction to the first rotating rod 6. The first rotating rod 6 and the second rotating rod 9 can rotate in the opposite direction with only one motor 5. The operation is simple and the structure is stable.

[0019] More specifically, in this embodiment, the two sides of the box body 15 are respectively fixedly connected to one end of a horizontally arranged fixing rod 23, and the other end of the fixing rod 23 is fixedly connected to the inner wall of the vessel body 1. In this invention, the fixing rod 23 can provide stable support and fixation for the box body 15, improving the overall structural stability.

[0020] Furthermore, the temperature control mechanism described in this embodiment includes several temperature sensors 24, which are arranged at fixed intervals from top to bottom. A heat exchange chamber 25 is provided inside the inner wall of the vessel body 1. The bottom of the heat exchange chamber 25 is connected to the steam inlet pipe 26 and the cooling medium inlet pipe 27. A steam inlet adjustment solenoid valve 28 is provided on the steam inlet pipe 26, and a cooling medium quantity adjustment solenoid valve 29 is provided on the cooling medium inlet pipe 27. The top of the heat exchange chamber 25 is connected to the steam outlet pipe 30 and the cooling medium outlet pipe 31. A steam outlet solenoid valve 32 is provided on the steam outlet pipe 30, and a cooling medium outlet solenoid valve 33 is provided on the cooling medium outlet pipe 31. In this invention, multiple temperature sensors 24 can collect temperature information at different depths of the vessel body 1 in real time. When heating is required, the steam inlet adjustment solenoid valve 28 and the steam outlet solenoid valve 32 are opened. Steam enters the heat exchange chamber 25 through the steam inlet pipe 26, heats the inside of the vessel body 1, and then flows out through the steam outlet pipe 30. The opening of the steam inlet adjustment solenoid valve 28 can be adjusted according to the temperature monitoring results, thereby adjusting the heating rate. When cooling is required, the cooling medium flow adjustment solenoid valve 29 and the cooling medium outlet solenoid valve 33 are opened. The cooling medium enters the heat exchange chamber 25, carries away the heat, and then flows out through the cooling medium outlet pipe 31. Similarly, the flow rate of the cooling medium can be adjusted according to the temperature to achieve precise temperature control.

[0021] Furthermore, in this embodiment, the top of the vessel body 1 is connected to the top of the storage container 34 via a pipeline, and a safety valve 35 is installed on the pipeline connecting the top of the vessel body 1 and the top of the storage container 34. In this invention, when the internal pressure of the vessel body 1 exceeds a set safety threshold, the safety valve 35 will automatically open, releasing excess high-pressure gas from the vessel body 1 into the storage container 34 for temporary storage, thus preventing overpressure in the vessel body 1 from causing a safety accident and improving operational safety.

[0022] Furthermore, in this embodiment, the bottom of the storage device 34 is connected to the top of the vessel body 1 via a pipeline. A recovery solenoid valve 36 and a recovery pump 37 are installed on the pipeline connecting the vessel body 1 and the bottom of the storage device 34. In this invention, when the internal pressure of the vessel body 1 drops to a safe range, the recovery solenoid valve 36 and the recovery pump 37 can be opened to transport the temporarily stored material in the storage device 34 back into the vessel body 1 to continue participating in the reaction. This avoids material waste, reduces reactant loss, and prevents the discharge of harmful materials that could cause pollution to the workshop and the external environment, ensuring full utilization of materials while avoiding environmental pollution.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
