Description

Technical Field

[0001] This invention relates to the field of chemical engineering, and more particularly to a chemical reaction vessel. Background Technology

[0002] A chemical reaction vessel is a device used for carrying out chemical reactions and is widely used in industries such as chemical, pharmaceutical, food, and energy.

[0003] Existing chemical reactors, when reacting solids, liquids, and gases, mostly employ stirring to mix materials, along with a temperature control system to regulate the reaction temperature and prepare reactants. However, when gas is introduced into the reactor, the gas is absorbed by the internal materials, and some unreacted gas is discharged, making it impossible to recycle. This affects the reaction quality and causes waste. Furthermore, most stirring components are suspended at the bottom, and high-speed rotation causes shaking, resulting in poor reactor stability.

[0004] Therefore, a chemical reaction vessel has been developed that can improve stirring stability, reduce vibration during stirring, recycle reaction gases, improve reaction quality, and reduce gas emission pollution and waste. Summary of the Invention

[0005] To overcome the shortcomings of existing reaction vessels, such as the inability to recycle unreacted gases and the fact that most stirring components are suspended at the bottom and cause shaking and instability due to high-speed rotation, this invention provides a chemical reaction vessel that can improve stirring stability, reduce vibration during stirring, recycle reaction gases, improve reaction quality, and reduce gas emission pollution and waste.

[0006] The technical solution of the present invention is as follows: a chemical reaction vessel, comprising a vessel body, a guide frame, a support base, a solid-liquid phase feeding pipe, a gas phase circulation mechanism, and a stirring mechanism. The guide frame is connected to the top of the vessel body, the support base is connected to the upper right side of the vessel body, and solid-liquid phase feeding pipes are connected to the upper front and rear sides of the vessel body. A gas phase circulation mechanism for recycling gas is provided on the upper right side of the vessel body, and a stirring mechanism for stirring the mixture inside the vessel body is provided on the guide frame.

[0007] Furthermore, the gas phase circulation mechanism includes a gas phase feeding connector, a first one-way valve, an inlet pipe, a gas filter, and a circulation pipe. The gas phase feeding connector is connected to the upper right side of the reactor body, and the inlet pipe is connected to the bottom of the gas phase feeding connector. The inlet pipe extends into the reactor body. The gas filter is connected to the upper right side of the reactor body, and a circulation pipe is connected between the gas filter and the gas phase feeding connector. The first one-way valve is connected to the left side of the circulation pipe. The gas phase feeding connector is connected to the gas injection pipe, and the gas phase reaction gas is introduced into the reactor body through the inlet pipe to react with the mixture inside the reactor body. After the reaction, part of the gas is introduced into the circulation pipe through the gas filter. The gas filter filters the gas after the reaction and discharges it into the gas phase feeding connector through the circulation pipe for reuse.

[0008] Furthermore, the mixing mechanism includes a lifting frame, a mixing motor, a lifting controller, a mounting shaft, mixing blades, and a stabilizing block. The lifting frame is slidably connected to the guide frame, and the mixing motor is connected to the lifting frame. The lifting controller is connected to the top of the support base, and the lifting controller is threadedly connected to the lifting frame and rotatably connected to the guide frame. The mounting shaft is connected to the output shaft of the mixing motor, and the lower part of the mounting shaft passes into the interior of the vessel. The lower part of the mounting shaft is connected to the mixing blades, and the bottom of the mounting shaft is rotatably connected to the stabilizing block, which is engaged with the bottom of the vessel. The output shaft of the mixing motor drives the mixing blades to rotate through the mounting shaft. The rotation of the mixing blades stirs the mixture inside the vessel. When the lifting controller controls the lifting frame to move upward on the guide frame, the mixing motor drives the mixing blades and the stabilizing block to move upward, allowing the mixture to be discharged through the bottom of the vessel.

[0009] Furthermore, it also includes a gas-phase mixing mechanism to prevent the gaseous reactant gases from accumulating in the upper layer inside the vessel. The gas-phase mixing mechanism includes a twisted bushing, a connecting frame, a piston, a sleeve, a second one-way valve, and a return gas pipe. The twisted bushing is slidably connected to the upper part of the mounting shaft, and the connecting frame is threadedly connected to the twisted bushing. The piston is connected to the upper right side of the connecting frame, and the sleeve is connected to the inner right side of the vessel. The piston passes into the sleeve and is slidably connected to the sleeve. The piston and the top of the sleeve are both connected to the second one-way valve, and the bottom of the sleeve is connected to the return gas pipe. The rotation of the mounting shaft drives the twisted bushing to rotate, and the rotation of the twisted bushing causes the connecting frame to drive the piston to move up and down inside the sleeve, drawing the gas in the upper layer inside the vessel into the sleeve and out through the return gas pipe, thus preventing the gaseous reactant gases from accumulating in the upper layer inside the vessel.

[0010] Furthermore, it also includes a solid mixing mechanism that causes the solid mixture that has settled in the lower middle part of the vessel to float. The solid mixing mechanism includes a rotating frame, a collection hood, and a guide pipe. The rotating frame is connected to the lower part of the mounting shaft, and the collection hood is connected to both the front and rear sides of the rotating frame. The guide pipe is connected to the collection hood. The rotating frame rotates with the mounting shaft, which drives the collection hood to rotate. The collection hood guides and captures the solid-liquid mixture in the lower middle part of the vessel, and under the action of centrifugal force, causes the solid mixture that has settled in the lower middle part of the vessel to float, thereby improving the reaction quality.

[0011] Furthermore, it also includes a refining mechanism for homogenizing and refining the introduced gas. The refining mechanism includes a split pipe, a guide pipe, and a refining mesh. The bottom of the inlet pipe is connected to the split pipe, and multiple guide pipes are connected to the split pipe. Each guide pipe is connected to a refining mesh. The gas is introduced into the split pipe through the inlet pipe and then into the guide pipe through the split pipe. The refining mesh then homogenizes and refines the introduced gas to improve the reaction efficiency.

[0012] Furthermore, it also includes a balancing mechanism to improve the stability of the piston movement. The balancing mechanism includes a fixed frame and a counterweight. The fixed frame is connected to the left side of the connecting frame, and the counterweight is connected to the bottom of the fixed frame. The fixed frame fixes the counterweight to the left side of the connection. The gravity of the counterweight and the kinetic energy of the piston movement on the right side of the connecting frame are combined to improve the stability of the piston movement.

[0013] Furthermore, the lifting controller includes a geared motor and a lead screw. The geared motor is connected to the top of the support base, and the lead screw is connected to the output shaft of the geared motor. The lead screw is threadedly connected to the lifting frame and rotatably connected to the guide frame.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The present invention filters the gas after the reaction through a body filter and discharges it into the gas phase feeding joint through a circulation pipe, so as to recycle the reaction gas. Combined with the operation of stabilizing the rotation of the stirring blades with a stabilizing block, it can improve the stirring stability, reduce the generation of vibration during stirring, and recycle the reaction gas, thereby improving the reaction quality and reducing gas emission pollution and waste.

[0015] 2. The present invention uses the rotation of the twisted bushing to cause the connecting frame to drive the piston to move up and down inside the sleeve, drawing the upper layer of gas inside the vessel into the sleeve and out through the return gas pipe. This operation can achieve the effect of drawing in the upper layer of gas inside the vessel, avoiding the accumulation of gaseous reaction gases in the upper layer inside the vessel, and improving the reaction quality and efficiency.

[0016] 3. This invention uses a rotating frame to drive the collection cover to rotate and guide and capture the solid-liquid mixture in the lower middle part of the reactor body. The mixture is then discharged through a drain pipe. This operation allows the settled solid mixture in the lower middle part of the reactor body to float, avoiding the settling of solid raw materials and improving the reaction quality.

[0017] 4. This invention uses a splitter tube to export the introduced reaction gas and a finer mesh to homogenize and refine the introduced gas, which can improve the reaction rate and increase the reaction efficiency.

[0018] 5. The present invention increases the weight on the left side of the connecting frame by adding a counterweight to adapt to the movement of the piston, thereby improving the stability of the piston during movement. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] A chemical reaction vessel, such as Figure 1 and Figure 2 As shown, it includes a vessel body 1, a guide frame 11, a support base 12, a solid-liquid phase feeding pipe 13, a gas phase circulation mechanism 2, and a stirring mechanism 3. The top of the vessel body 1 is connected to the guide frame 11, the upper right side of the vessel body 1 is connected to the support base 12, the upper front and rear sides of the vessel body 1 are both connected to the solid-liquid phase feeding pipe 13, the upper right side of the vessel body 1 is provided with the gas phase circulation mechanism 2, and the guide frame 11 is provided with the stirring mechanism 3.

[0030] like Figures 1-3 As shown, the gas phase circulation mechanism 2 includes a gas phase feeding connector 20, a first one-way valve 201, an air inlet pipe 21, a gas filter 22, and a circulation pipe 23. The gas phase feeding connector 20 is connected to the upper right side of the vessel body 1. The bottom of the gas phase feeding connector 20 is connected to the air inlet pipe 21, which extends into the interior of the vessel body 1. The gas filter 22 is connected to the upper right side of the vessel body 1. The circulation pipe 23 is connected between the gas filter 22 and the gas phase feeding connector 20. The first one-way valve 201 is connected to the left side of the circulation pipe 23.

[0031] like Figures 1-3 As shown, the stirring mechanism 3 includes a lifting frame 30, a stirring motor 31, a lifting controller 32, a mounting shaft 33, stirring blades 34, and a stabilizing block 35. The lifting frame 30 is slidably connected to the guide frame 11, and the stirring motor 31 is connected to the lifting frame 30. The lifting controller 32 is connected to the top of the support base 12. The lifting controller 32 is threadedly connected to the lifting frame 30 and rotatably connected to the guide frame 11. The lifting controller 32 includes a reduction motor and a lead screw. The reduction motor is connected to the top of the support base 12. The lead screw is connected to the output shaft of the reduction motor. The lead screw is threadedly connected to the lifting frame 30 and rotatably connected to the guide frame 11. The mounting shaft 33 is connected to the output shaft of the stirring motor 31. The lower part of the mounting shaft 33 penetrates into the interior of the vessel body 1. The stirring blades 34 are connected to the lower part of the mounting shaft 33. The stabilizing block 35 is rotatably connected to the bottom of the mounting shaft 33 and is engaged with the bottom of the vessel body 1.

[0032] In use, the present invention first controls the stirring motor 31 via the lifting controller 32 to move the mounting shaft 33 and the stabilizing block 35 downwards, so that the stabilizing block 35 contacts the bottom of the vessel body 1. Then, the solid and liquid raw materials to be reacted and mixed are introduced into the vessel body 1 through the solid-liquid phase feeding pipe 13. When reaction gas needs to be injected, an external gas injection pipe is connected through the gas phase feeding connector 20. The gas phase feeding connector 20 is connected to the gas injection pipe, and the gas phase reaction gas is introduced into the vessel body 1 through the gas inlet pipe 21. The first one-way valve 201 on the circulation pipe 23 ensures that the injected gas can only be introduced into the vessel body 1 through the gas inlet pipe 21 and cannot enter the circulation pipe 23 during gas injection. The gas phase reaction gas reacts with the mixture inside the vessel body 1. After the reaction, part of the gas is introduced into the circulation pipe 23 through the gas filter 22. The gas filter 22 filters the gas after the reaction and discharges it into the gas phase feeding connector 20 through the circulation pipe 23 for reuse. The reaction gas, solid raw materials and liquid raw materials are then recycled. After the addition is complete, the stirring motor 31 can be started. The output shaft of the stirring motor 31 drives the stirring blades 34 to rotate through the mounting shaft 33. The rotation of the stirring blades 34 stirs the mixture inside the vessel 1. The stabilizing block 35 stabilizes the rotation of the mounting shaft 33, reducing the shaking caused by stirring, so that the solid, liquid and gaseous raw materials are fully mixed. After the mixing reaction is completed, the lifting controller 32 controls the lifting frame 30 to move upward on the guide frame 11, so that the stirring motor 31 drives the stirring blades 34 and the stabilizing block 35 to move upward. The mixture can be discharged through the bottom of the vessel 1. The gas after the reaction is filtered through the above-mentioned body filter and discharged into the gas phase feeding joint 20 through the circulation pipe 23 for recycling of the reaction gas. In conjunction with the operation of the stabilizing block 35 to stabilize the rotation of the stirring blades 34, the stirring stability can be improved, the vibration generated during stirring can be reduced, the reaction gas can be recycled, the reaction quality can be improved, and the gas emission pollution and waste can be reduced.

[0033] like Figure 2 and Figure 4 As shown, it also includes a gas phase mixing mechanism 4, which includes a twisted bushing 40, a connecting frame 41, a piston 42, a sleeve 43, a second one-way valve 44, and a return gas pipe 45. The twisted bushing 40 is slidably connected to the upper part of the mounting shaft 33, and the connecting frame 41 is threadedly connected to the twisted bushing 40. The piston 42 is connected to the upper right side of the connecting frame 41, and the sleeve 43 is connected to the inner right side of the vessel body 1. The piston 42 passes into the sleeve 43 and is slidably connected to the sleeve 43. The second one-way valve 44 is connected to the top of both the piston 42 and the sleeve 43, and the return gas pipe 45 is connected to the bottom of the sleeve 43.

[0034] Using the gas-phase mixing mechanism 4 of the present invention, it is possible to prevent the gaseous reactant gas from accumulating in the upper layer inside the vessel body 1. The rotation of the mounting shaft 33 drives the twisted bushing 40 to rotate. The rotation of the twisted bushing 40 causes the connecting frame 41 to drive the piston 42 to move up and down inside the sleeve 43, drawing the gas in the upper layer inside the vessel body 1 into the sleeve 43 and out through the return gas pipe 45. The cooperation of the second one-way valve 44 ensures that the gas can only flow downward, preventing the gaseous reactant gas from accumulating in the upper layer inside the vessel body 1. Through the above-mentioned operation of the twisted bushing 40 rotating to drive the connecting frame 41 to drive the piston 42 to move up and down inside the sleeve 43, drawing the gas in the upper layer inside the vessel body 1 into the sleeve 43 and out through the return gas pipe 45, it is possible to achieve the effect of drawing in the gas in the upper layer inside the vessel body 1, preventing the gaseous reactant gas from accumulating in the upper layer inside the vessel body 1, and improving the reaction quality and efficiency.

[0035] like Figure 2 , Figure 5 and Figure 6 As shown, it also includes a solid phase mixing mechanism 5, which includes a rotating frame 50, a collection cover 51 and a drain pipe 52. The rotating frame 50 is connected to the lower part of the mounting shaft 33. The collection cover 51 is connected to both the front and rear sides of the rotating frame 50, and the drain pipe 52 is connected to both the collection cover 51.

[0036] Using the solid-phase mixing mechanism 5 of the present invention, the solid mixture that has settled in the lower middle part of the vessel 1 can be made to float. The rotating frame 50 rotates with the mounting shaft 33, driving the collecting cover 51 to rotate. The collecting cover 51 guides and captures the solid-liquid mixture in the lower middle part of the vessel 1, and discharges it through the drain pipe 52 under the action of centrifugal force, so that the solid mixture that has settled in the lower middle part of the vessel 1 floats, improving the reaction quality. By rotating the collecting cover 51 with the rotating frame 50 to guide and capture the solid mixture in the lower middle part of the vessel 1, and then discharging it through the drain pipe 52, the solid mixture that has settled in the lower middle part of the vessel 1 can be made to float, avoiding the settling of solid raw materials and improving the reaction quality.

[0037] like Figure 2 and Figure 7 As shown, it also includes a refining mechanism 6, which includes a split pipe 60, a guide pipe 61 and a refining mesh 62. The bottom of the intake pipe 21 is connected to the split pipe 60, and multiple guide pipes 61 are connected to the split pipe 60. Each guide pipe 61 is connected to a refining mesh 62.

[0038] Using the refining mechanism 6 of the present invention, the introduced gas can be homogenized and refined. The gas is introduced into the diversion pipe 60 through the inlet pipe 21, and then into the guide pipe 61 through the diversion pipe 60. The refining mesh 62 then homogenizes and refines the introduced gas, thereby improving the reaction efficiency. The introduced reaction gas is discharged through the diversion pipe 60. The operation of homogenizing and refining the introduced gas with the refining mesh 62 can improve the reaction rate of the reaction gas and increase the reaction efficiency.

[0039] like Figure 2 and Figure 8 As shown, it also includes a balancing mechanism 7, which includes a fixed frame 70 and a counterweight 71. The fixed frame 70 is connected to the left side of the connecting frame 41, and the counterweight 71 is connected to the bottom of the fixed frame 70. The fixed frame 70 fixes the counterweight 71 to the left side of the connection.

[0040] Using the balancing mechanism 7 of the present invention, the stability of the piston 42 during movement can be improved. By coordinating the gravity of the counterweight 71 with the kinetic energy generated by the movement of the piston 42 on the right side of the connecting frame 41, the stability of the piston 42 during movement can be improved. By increasing the weight on the left side of the connecting frame 41 with the counterweight 71 to match the movement of the piston 42, the stability of the piston 42 during movement can be improved.

[0041] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
