Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of reaction vessels, in particular to an explosion-proof reaction kettle. BACKGROUND

[0002] In many industries such as chemical industry and pharmaceutical industry, reaction kettle is one of the key equipment. It is used to carry out various chemical reactions, such as polymerization reaction, oxidation-reduction reaction, etc. However, many chemical reaction processes involve flammable and explosive gases, liquids or solid substances. For example, in the field of petroleum chemical industry, the cracking reaction of crude oil will produce a large amount of hydrocarbon gas. When these gases are mixed with air, they may explode once they come into contact with a fire source or reach a certain energy excitation condition. According to statistics, accidents caused by explosion of reaction kettle account for a high proportion in the chemical industry, which has caused great harm to personnel life safety, enterprise property and environment.

[0003] In the prior art, when producing a solution, there is also a part of the solution in the residual raw material residue after production is completed. These can form an appreciable amount if collected. At the same time, when the solution is heated for production, the heating area in the reaction kettle is very easy to appear local overheating due to the position relationship of the heater itself. Therefore, to solve the above problems, we provide an explosion-proof reaction kettle. SUMMARY

[0004] The present application solves the technical problem of how to heat the solution as a whole during solution production to avoid local overheating, and to recover the residual solution in the raw material residue by extrusion after solution production is completed, and provides an explosion-proof reaction kettle.

[0005] The technical solution adopted by the present application to solve the technical problem is:

[0006] An explosion-proof reaction kettle comprises a reaction device, a residue extrusion device, a heating device, a support frame and a controller.

[0007] The support frame is arranged on the ground. The reaction device is arranged on the support frame and is used for mixing and producing raw materials. The residue extrusion device is arranged on the reaction device and is used for extruding and recovering the solution in the raw material residue. The heating device is arranged on the reaction device and is used for heating the raw materials. The controller is arranged on the side of the support frame and on the ground. The controller is electrically connected with the reaction device, the residue extrusion device and the heating device.

[0008] The reaction apparatus thoroughly mixes solid and liquid raw materials fed into it to form a solution. The residue extrusion device recovers a portion of the solution remaining in the raw material residue after production. The heating device heats the solution as a whole during the mixing process. In this way, the equipment achieves the technical effect of heating the solution as a whole during production to avoid localized overheating, and simultaneously recovering the remaining solution from the raw material residue through extrusion after production.

[0009] Furthermore, the reaction apparatus includes: a reaction vessel, a material container, a drive motor, a shell, a solenoid valve, a discharge pipe, a cover, and a safety valve.

[0010] The reaction vessel is vertically installed inside the support frame, and the reaction vessel is fixedly connected to the inner wall of the support frame.

[0011] One end of the safety valve extends horizontally through the side of the reaction tank and is fixedly connected to the side of the reaction tank. The axis of the safety valve is perpendicular to the axis of the reaction tank, and one end is connected to the inside of the reaction tank, while the other end is connected to the exhaust gas treatment tower through a gas pipe.

[0012] The outer shell is located below the reaction vessel, and the top surface of the outer shell is fixedly connected to the outer bottom surface of the reaction vessel.

[0013] The rotating shaft of the drive motor runs vertically through the top of the outer shell and the bottom of the reaction vessel, with its axis coinciding with the axis of the reaction vessel. The housing of the drive motor is fixedly connected to the inner wall of the outer shell, and the rotating shaft of the drive motor is sealed and rotatably connected to the top of the outer shell and the bottom of the reaction vessel. The drive motor is also electrically connected to the controller.

[0014] The material container is vertically installed inside the reaction vessel, with its axis coinciding with the axis of the reaction vessel. The material container is mounted on the rotating shaft of the drive motor, and the bottom surface of the material container is in close contact with the inner bottom surface of the reaction vessel. Several holes are staggered on the side of the material container, and several holes communicate with the interior of the reaction vessel.

[0015] One end of the solenoid valve extends vertically through the top of the outer shell and the bottom of the reaction vessel, located to the side of the drive motor. The other end of the solenoid valve is connected to the interior of the reaction vessel and is also electrically connected to the controller.

[0016] The discharge pipe is an L-shaped pipe. One end of the discharge pipe passes through the side of the outer shell and is connected to the other end of the solenoid valve. The other end of the discharge pipe is connected to the outside.

[0017] The cap is positioned above the reaction vessel and is threadedly connected to the outer side of the reaction vessel.

[0018] Furthermore, the container is made of polytetrafluoroethylene (PTFE).

[0019] When a user wants to produce ethanol from biomass fermentation, the user first unscrews the cap from the reaction vessel. Then, the user separately feeds the solid and liquid raw materials into the receiving tank. After entering the receiving tank, the liquid raw material passes through several holes in the receiving tank into the reaction vessel. The user then places the cap back onto the reaction vessel and secures it by rotating the handle.

[0020] Then, the drive motor is started, which rotates the container, causing the solid and liquid raw materials inside the container and the liquid raw materials inside the reaction vessel to rotate. This allows the solid and liquid raw materials to be thoroughly mixed through centrifugation, concentrating larger raw material particles in the solution into a single area.

[0021] Once the solution inside the reaction tank has mixed to a certain extent, the internal pressure will increase. The safety valve, sensing this pressure increase, will automatically open, allowing gas from the reaction tank to flow through the safety valve and gas pipe into the waste gas treatment tower. The safety valve will automatically close once the internal pressure of the reaction tank matches the external pressure. This process automatically depressurizes the reaction tank.

[0022] Once the solution inside the reaction tank has been mixed and processed, the user controls the drive motor to stop and the solenoid valve to open. After the solenoid valve opens, the solution inside the reaction tank gradually passes through the solenoid valve and the discharge pipe, where it is collected by the user.

[0023] Furthermore, the residue extrusion device includes: four vertical keys, a cylinder, an extrusion plate, a limit ring, several floats, and several balls.

[0024] The cylinder's axis coincides with the axis of the material container. The cylinder is located in the middle of the cover, above the material container. The cylinder's housing is fixedly connected to the cover, and the cylinder is also electrically connected to the controller.

[0025] The extrusion plate is circular, and its axis coincides with the axis of the material container. The extrusion plate is set inside the reaction vessel, below the cylinder. The top surface of the extrusion plate is fixedly connected to the telescopic rod of the cylinder. The diameter of the extrusion plate is smaller than the inner diameter of the material container.

[0026] The four vertical keys are respectively set on the rotating shaft of the drive motor, located inside the reaction vessel. The four vertical keys are fixedly connected to the rotating shaft of the drive motor. The bottom of the material container is fitted onto the four vertical keys, and the bottom is slidably connected to the four vertical keys in a sealed manner.

[0027] Four floats are inclinedly installed inside the reaction vessel, located on the sides of the material container, and are fixedly connected to the bottom outer side of the material container.

[0028] The limiting ring is set inside the reaction tank, with its center coinciding with the axis of the reaction tank. It is located between the extrusion plate and the four floating plates. The outer ring surface of the limiting ring is fixedly connected to the inner wall of the reaction tank. The distance between the limiting ring and the inner bottom surface of the reaction tank is smaller than the distance between the extrusion plate and the top surface of the feeding tank.

[0029] Several balls are respectively set on the top of the four floats and are located below the limiting rings.

[0030] Furthermore, a scraper is fitted on the outer ring surface of the extrusion plate, and the diameter of the scraper matches the inner diameter of the material container.

[0031] Furthermore, the bottom of the extrusion plate is provided with a groove, the axis of which coincides with the axis of rotation of the drive motor, and the radius of the groove is greater than the distance from the vertical key to the axis of rotation of the drive motor.

[0032] Furthermore, it also includes a pressure sensor. The pressure sensor is installed on the bottom surface inside the reaction vessel, directly below the material container, and in contact with the bottom surface of the material container. The pressure sensor is fixedly connected to the bottom surface inside the reaction vessel and electrically connected to the controller.

[0033] When the liquid raw material enters the container, several floats will rise due to the buoyancy of the liquid. The rising of the floats will drive several ball bearings and the container to rise. The container will rise along the four vertical keys until the ball bearings contact the bottom surface of the limit ring, at which point the floats, ball bearings, and container will stop rising.

[0034] When the floats rotate, they drive the ball bearings to rotate as well. These ball bearings then roll along the bottom surface of the limiting ring, preventing direct contact between the floats and the limiting ring. Simultaneously, the rotation of the floats also ensures that the liquid below the limiting ring is thoroughly mixed with the liquid in other areas of the reaction vessel.

[0035] Once the solutions inside the reaction tank and the holding tank have been discharged through the solenoid valve and the discharge pipe, the user activates the cylinder to extend. This extension moves the extrusion plate downwards into the holding tank, which in turn moves the scraper downwards, scraping away any remaining material residue from the inner wall of the holding tank until all residue is concentrated at the bottom. The extrusion plate then continues to move downwards, applying pressure to the residue. This pressure is transmitted to the reaction tank, which in turn transmits it to the pressure sensor. Once the pressure sensor reaches its maximum set pressure value, it sends a control signal to the controller. Upon receiving this signal, the controller retracts the cylinder, causing the extrusion plate to rise. This rise, in turn, moves the scraper upwards until the cylinder returns to its original position. This process squeezes out any remaining solution from the residue and discharges it from the reaction tank through several holes in the holding tank, the solenoid valve, and the discharge pipe, thus completing the recovery of the solution from the residue.

[0036] Once the solution recovery of the raw material residue is complete and it has been compressed into blocks, the user can remove the cap from the reaction vessel again, clean out the raw material residue, and clean the reaction vessel and the container. After that, the solenoid valve is closed, and the cap is installed back on the reaction vessel.

[0037] Furthermore, the heating device includes: several heating rods and a flow-disrupting component.

[0038] Several heating rods are arranged horizontally inside the housing, on the side of the drive motor. The heating rods are fixedly connected to the inner top surface of the housing and electrically connected to the controller.

[0039] The turbulence-disrupting component is located inside the reaction vessel and is used to turbulently stir the solution.

[0040] Furthermore, the aerodynamic components include: several rotating rods, several bevel gears, bevel gear rings, several blades, and several rotating ports.

[0041] Several rotating rods are horizontally arranged inside the reaction tank, with their axes perpendicular to the axis of the reaction tank and positioned above the limiting ring. One end of each rotating rod is rotatably connected to the inner wall of the reaction tank, and the axis of rotation coincides with its own axis.

[0042] Several rotating ports are respectively set on the limiting ring, located directly below the rotating rod, and connected vertically.

[0043] Several bevel gears are respectively fitted onto several rotating rods, and their lower parts pass through several rotating openings. The bevel gears are respectively fixedly connected to the sides of the rotating rods.

[0044] Several blades are respectively disposed on the sides of several rotating rods, and are respectively positioned between the limiting ring and the reaction tank. Several blades are respectively fixedly connected to the sides of several rotating rods.

[0045] The axis of the bevel gear ring coincides with the axis of the material container. The bevel gear ring is sleeved on the outside of the material container and is set on the top surface of several floats, respectively located below several bevel gears. The bevel gear ring is fixedly connected to the top surface of several floats and corresponds to several bevel gears.

[0046] Furthermore, some of the blades are trapezoidal in shape.

[0047] The bevel ring can mesh with several bevel gears.

[0048] When several floats rotate, they also drive the conical gear ring to rotate. Simultaneously, when several heating rods are activated, the conical gear ring rotates, and the ring rotates to a position below and in contact with several bevel gears, the activation of the heating rods dissipates heat, which is transferred through the outer shell and reaction vessel to the solution inside the reaction vessel. After the conical gear ring contacts the bevel gears, the ring and gears mesh, driving the gears to rotate. This rotation of the bevel gears drives several rotating rods, which in turn drive several paddles, thus agitating the heated solution below the limiting ring of the reaction vessel and preventing localized overheating.

[0049] The beneficial effects of this invention are:

[0050] 1. This invention comprises a reaction device, a residue extrusion device, a heating device, a support frame, and a controller. The reaction device thoroughly mixes solid and liquid raw materials fed into it to form a solution. The residue extrusion device recovers a portion of the solution remaining in the raw material residue after production. The heating device heats the solution as a whole during the mixing process. In this way, the equipment achieves the technical effect of heating the solution as a whole during production to avoid localized overheating, and recovering the remaining solution in the raw material residue through extrusion after production.

[0051] 2. This invention, through the arrangement of four vertical keys, a cylinder, a pressing plate, a limiting ring, several floats, and several ball bearings, enables the extrusion and collection of residual solution from the raw material residue after solution production.

[0052] 3. This invention, by incorporating several heating rods, rotating rods, bevel gears, bevel gear rings, impellers, and rotating ports, achieves agitation of the heated solution below the limiting ring of the reaction tank, thus preventing localized overheating of the solution within the reaction tank.

[0058] The following will describe the concept and technical effects of the present invention clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of the present invention.

[0059] Please see Figures 1-3 :

[0060] An explosion-proof reactor includes: a reaction device, a residue compression device, a heating device, a support frame 1, and a controller.

[0061] Support frame 1 is mounted on the ground. The reaction unit is mounted on support frame 1 and is used for mixing and processing raw materials. A residue extrusion device is mounted on the reaction unit and is used for extruding and recovering the solution from the raw material residue. A heating device is mounted on the reaction unit and is used for heating the raw materials. A controller is located to the side of support frame 1 and on the ground; the controller is electrically connected to the reaction unit, the residue extrusion device, and the heating device.

[0062] The reaction apparatus thoroughly mixes solid and liquid raw materials fed into it to form a solution. The residue extrusion device recovers a portion of the solution remaining in the raw material residue after production. The heating device heats the solution as a whole during the mixing process. In this way, the equipment achieves the technical effect of heating the solution as a whole during production to avoid localized overheating, and simultaneously recovering the remaining solution from the raw material residue through extrusion after production.

[0063] The reaction apparatus includes: a reaction tank 20, a material container 21, a drive motor 22, an outer shell 23, a solenoid valve 24, a discharge pipe 25, a cover 26, and a safety valve 27.

[0064] The reaction vessel 20 is vertically installed inside the support frame 1, and the reaction vessel 20 is fixedly connected to the inner wall of the support frame 1.

[0065] One end of the safety valve 27 extends laterally through the side of the reaction tank 20 and is fixedly connected to the side of the reaction tank 20. The axis of the safety valve 27 is perpendicular to the axis of the reaction tank 20, and one end is connected to the inside of the reaction tank 20, while the other end is connected to the exhaust gas treatment tower through a gas pipe.

[0066] The outer shell 23 is located below the reaction vessel 20, and the top surface of the outer shell 23 is fixedly connected to the outer bottom surface of the reaction vessel 20.

[0067] The rotating shaft of the drive motor 22 extends vertically through the top of the outer shell 23 and the bottom of the reaction vessel 20, with its axis coinciding with the axis of the reaction vessel 20. The housing of the drive motor 22 is fixedly connected to the inner wall of the outer shell 23. The rotating shaft of the drive motor 22 is sealed and rotatably connected to the top of the outer shell 23 and the bottom of the reaction vessel 20. The drive motor 22 is also electrically connected to the controller.

[0068] The material container 21 is vertically installed inside the reaction vessel 20, with its axis coinciding with the axis of the reaction vessel 20. The material container 21 is mounted on the rotating shaft of the drive motor 22. The bottom surface of the material container 21 is in close contact with the inner bottom surface of the reaction vessel 20. Several holes are staggered on the side of the material container 21, and several holes communicate with the interior of the reaction vessel 20.

[0069] One end of the solenoid valve 24 extends vertically through the top of the outer casing 23 and the bottom of the reaction vessel 20, and is located on the side of the drive motor 22. One end of the solenoid valve 24 is connected to the interior of the reaction vessel 20, and the solenoid valve 24 is also electrically connected to the controller.

[0070] The discharge pipe 25 is an L-shaped pipe. One end of the discharge pipe 25 passes through the side of the outer shell 23 and is connected to the other end of the solenoid valve 24. The other end of the discharge pipe 25 is connected to the outside.

[0071] The cap 26 is positioned above the reaction vessel 20 and is threadedly connected to the outer side of the reaction vessel 20.

[0072] The container 21 is made of polytetrafluoroethylene.

[0073] When a user wants to produce ethanol from biomass fermentation, the user first unscrews the cap 26 from the reaction vessel 20. Then, the user adds the solid and liquid raw materials to the receiving container 21 respectively. After entering the receiving container 21, the liquid raw material passes through several holes in the receiving container 21 into the reaction vessel 20. The user then places the cap 26 on the reaction vessel 20 and secures it by rotating the handle.

[0074] Then, the drive motor 22 is started, which drives the material container 21 to rotate. The rotation of the material container 21 causes the solid raw materials, liquid raw materials, and liquid raw materials inside the reaction vessel 20 to rotate. This allows the solid raw materials to be fully mixed with the liquid raw materials through centrifugation, concentrating larger raw material particles in the solution into one area.

[0075] Once the solution inside reaction vessel 20 has mixed to a certain extent, the internal pressure will increase. Safety valve 27, sensing this increase, will automatically open, allowing gas from inside reaction vessel 20 to flow through safety valve 27 and the gas pipe into the waste gas treatment tower. The pressure will continue until it matches the external pressure, at which point safety valve 27 will automatically close. This process automatically depressurizes reaction vessel 20.

[0076] Once the solution inside the reaction vessel 20 has been mixed and processed, the user controls the drive motor 22 to stop and the solenoid valve 24 to open. After the solenoid valve 24 is opened, the solution inside the reaction vessel 20 will gradually pass through the solenoid valve 24 and the discharge pipe 25 and be collected by the user.

[0077] The residue extrusion device includes: four vertical keys 30, a cylinder 31, an extrusion plate 32, a limit ring 33, several floats 34, and several balls 35.

[0078] The axis of cylinder 31 coincides with the axis of the material container 21. Cylinder 31 is located in the middle of the cover 26, above the material container 21. The housing of cylinder 31 is fixedly connected to the cover 26. Cylinder 31 is also electrically connected to the controller.

[0079] The extrusion plate 32 is circular, and its axis coincides with the axis of the material container 21. The extrusion plate 32 is set inside the reaction tank 20, below the cylinder 31. The top surface of the extrusion plate 32 is fixedly connected to the telescopic rod of the cylinder 31. The diameter of the extrusion plate 32 is smaller than the inner diameter of the material container 21.

[0080] Four vertical keys 30 are respectively set on the rotating shaft of the drive motor 22 and located inside the reaction vessel 20. The four vertical keys 30 are fixedly connected to the rotating shaft of the drive motor 22. The bottom of the material container 21 is fitted on the four vertical keys 30 and the bottom is in a sealed sliding connection with the four vertical keys 30.

[0081] Four floats 34 are inclinedly arranged inside the reaction tank 20, respectively located on the side of the material container 21, and the four floats 34 are fixedly connected to the bottom outer side of the material container 21.

[0082] The limiting ring 33 is set inside the reaction tank 20, with its center coinciding with the axis of the reaction tank 20. It is located between the extrusion plate 32 and the four floating plates 34. The outer ring surface of the limiting ring 33 is fixedly connected to the inner wall of the reaction tank 20. The distance between the limiting ring 33 and the inner bottom surface of the reaction tank 20 is smaller than the distance between the extrusion plate 32 and the top surface of the material container 21.

[0083] Several balls 35 are respectively disposed on the top of the four floats 34 and are respectively located below the limiting rings 33.

[0084] A scraper is fitted on the outer ring surface of the extrusion plate 32, and the diameter of the scraper matches the inner diameter of the material container 21.

[0085] The bottom of the extrusion plate 32 is provided with a groove, the axis of which coincides with the axis of rotation of the drive motor 22, and the radius of the groove is greater than the distance from the vertical key 30 to the axis of rotation of the drive motor 22.

[0086] It also includes a pressure sensor. The pressure sensor is located on the bottom surface inside the reaction vessel 20, directly below the material container 21, and in contact with the bottom surface of the material container 21. The pressure sensor is fixedly connected to the bottom surface inside the reaction vessel 20 and electrically connected to the controller.

[0087] When the liquid raw material enters the container 21, several floats 34 will rise due to the buoyancy of the liquid. The rising of the floats 34 will drive the several balls 35 and the container 21 to rise. The rising of the container 21 will rise along the four vertical keys 30 until the balls 35 contact the bottom surface of the limiting ring 33, at which point the floats 34, the balls 35 and the container 21 will stop rising.

[0088] When the floats 34 rotate, they drive the balls 35 to rotate as well. The balls 35 then roll along the bottom surface of the limiting ring 33, thus preventing direct contact between the floats 34 and the limiting ring 33. Simultaneously, the rotation of the floats 34 also ensures that the liquid below the limiting ring 33 is thoroughly mixed with the liquid in other areas of the reaction vessel 20.

[0089] When the solutions inside the reaction tank 20 and the storage tank 21 are discharged through the solenoid valve 24 and the discharge pipe 25, the user then activates the cylinder 31 to extend. The extension of the cylinder 31 causes the extrusion plate 32 to move downwards into the storage tank 21. The downward movement of the extrusion plate 32 causes the scraper to move downwards into the storage tank 21. The scraper scrapes out the raw material residue on the inner wall of the storage tank 21 until all the raw material residue inside the storage tank 21 is concentrated at the bottom of the storage tank 21. At this time, the extrusion plate 32 continues to move downwards, applying pressure to the raw material residue. The pressure on the raw material residue is transmitted to the reaction tank 20, and the pressure on the reaction tank 20 is transmitted to the pressure sensor. When the pressure sensor reaches its set maximum pressure sensing value, the pressure sensor sends a control signal to the controller. After receiving the control signal, the controller controls the cylinder 31 to retract. The retraction of the cylinder 31 causes the extrusion plate 32 to rise, and the rise of the extrusion plate 32 causes the scraper to rise until the cylinder 31 returns to its original position. This process squeezes out the residual solution from the raw material residue and discharges it from the reaction tank 20 through several holes in the holding tank 21, the solenoid valve 24, and the discharge pipe 25. This completes the recovery of the solution from the raw material residue.

[0090] After the solution of the raw material residue is recovered and compressed into blocks, the user can remove the cap 26 from the reaction tank 20 again, clean out the raw material residue, clean the reaction tank 20 and the material container 21, close the solenoid valve 24, and install the cap 26 on the reaction tank 20.

[0091] The heating device includes: several heating rods 40 and a flow-disrupting component.

[0092] Several heating rods 40 are arranged horizontally inside the housing 23, on the side of the drive motor 22. The heating rods 40 are fixedly connected to the inner top surface of the housing 23 and electrically connected to the controller.

[0093] The turbulence-disrupting component is located inside the reaction vessel 20 and is used to turbulently stir the solution.

[0094] The turbulence-causing components include: several rotating rods 41, several bevel gears 42, bevel gear rings 43, several blades 44, and several rotating ports 45.

[0095] Several rotating rods 41 are respectively arranged horizontally inside the reaction tank 20, with their axes perpendicular to the axis of the reaction tank 20 and above the limiting ring 33. One end of each rotating rod 41 is rotatably connected to the inner wall of the reaction tank 20, and the axis of rotation coincides with its own axis.

[0096] Several rotating ports 45 are respectively set on the limiting ring 33, located directly below the rotating rod 41, and connected vertically.

[0097] Several bevel gears 42 are respectively sleeved on several rotating rods 41, and their lower parts pass through several rotating openings 45 respectively. The bevel gears 42 are respectively fixedly connected to the side of several rotating rods 41.

[0098] Several blades 44 are respectively disposed on the side of several rotating rods 41, and are respectively located between the limiting ring 33 and the reaction tank 20. Several blades 44 are respectively fixedly connected to the side of several rotating rods 41.

[0099] The axis of the bevel gear ring 43 coincides with the axis of the material container 21. The bevel gear ring 43 is sleeved on the outside of the material container 21 and is set on the top surface of several floats 34. It is located below several bevel gears 42. The bevel gear ring 43 is fixedly connected to the top surface of several floats 34 and corresponds to several bevel gears 42.

[0100] Several blades 44 are trapezoidal in shape.

[0101] The bevel ring 43 and several bevel gears 42 can mesh with each other.

[0102] When the floats 34 rotate, they also drive the bevel ring 43 to rotate. Simultaneously, when the heating rods 40 are activated, the bevel ring 43 rotates, and the bevel ring 43 rotates to a position below and in contact with the bevel gears 42, the activation of the heating rods 40 dissipates heat, which is transferred through the outer shell 23 and the reaction tank 20 to the solution inside the reaction tank 20. After the bevel ring 43 contacts the bevel gears 42, the bevel ring 43 and the bevel gears 42 mesh with each other, driving the bevel gears 42 to rotate. The rotation of the bevel gears 42 drives the rotation of the rotating rods 41, which in turn drives the rotation of the paddles 44. This agitates the heated solution below the limiting ring 33 of the reaction tank 20, preventing localized overheating of the solution in the reaction tank 20.

[0103] Work process:

[0104] When a user wants to produce ethanol from biomass fermentation, the user first unscrews the cap 26 from the reaction tank 20. As the cap 26 rotates and rises, it drives the cylinder 31 to rotate and rise, and the cylinder 31 drives the extrusion plate 32 to rotate and rise until the cap 26 is removed from the reaction tank 20.

[0105] The user then adds the solid and liquid raw materials into the container 21 respectively. After entering the container 21, the liquid raw material passes through several holes in the container 21 and enters the reaction vessel 20. The user then places the cap 26 on the reaction vessel 20 and fixes the cap 26 on the reaction vessel 20 by rotating the handle. The rotation of the cap 26 drives the cylinder 31 to rotate, and the rotation of the cylinder 31 drives the extrusion plate 32 to rotate until the cap 26 is fixed on the reaction vessel 20.

[0106] When the liquid raw material enters the container 21, several floats 34 will rise due to the buoyancy of the liquid. The rising of the floats 34 will drive the balls 35, the conical ring 43, and the container 21 to rise. The rising of the container 21 will follow the four vertical keys 30 until the balls 35 contact the bottom surface of the limiting ring 33, at which point the floats 34, balls 35, conical ring 43, and container 21 will stop rising.

[0107] Then, the drive motor 22 and several heating rods 40 are started. The drive motor 22 drives the four vertical keys 30 to rotate, which in turn drives the material container 21 to rotate. The rotation of the material container 21 causes the solid raw materials, liquid raw materials, and liquid raw materials inside the reaction vessel 20 to rotate, and at the same time, it also drives several floats 34 to rotate. This allows the solid raw materials to be fully mixed with the liquid raw materials through centrifugation, concentrating and confining larger raw material particles in the solution to one area. At the same time, the rotation of the floats 34 also allows the liquid below the limiting ring 33 to be fully mixed with the liquid in other areas of the reaction vessel 20.

[0108] When the floats 34 rotate, they drive the balls 35 and the bevel ring 43 to rotate. As the balls 35 rotate, they can roll along the bottom surface of the limiting ring 33. This prevents the floats 34 from directly contacting the limiting ring 33.

[0109] When the heating rods 40 are activated and the bevel ring 43 rotates, reaching a position below and contacting the bevel gears 42, the heating rods 40 emit heat, which is transferred through the outer casing 23 and the reaction vessel 20 to the solution inside the reaction vessel 20. After the bevel ring 43 contacts the bevel gears 42, they mesh, causing the bevel gears 42 to rotate. This rotation of the bevel gears 42 then drives the rotating rods 41 to rotate, which in turn drives the paddles 44 to rotate. This agitates the heated solution below the limiting ring 33 of the reaction vessel 20, preventing localized overheating of the solution.

[0110] When the temperature inside the reaction vessel 20 rises and the solution mixes to a certain extent, the gas pressure inside the reaction vessel 20 will increase. Upon sensing this increase in pressure, the safety valve 27 will automatically open, allowing the gas inside the reaction vessel 20 to flow through the safety valve 27 and the gas pipe into the waste gas treatment tower. The pressure inside the reaction vessel 20 will continue until it matches the external pressure, at which point the safety valve 27 will automatically close. This process automatically depressurizes the reaction vessel 20.

[0111] Once the solution inside the reaction vessel 20 has been mixed and processed, the user controls the drive motor 22 to stop, the heating rods 40 to shut off, and the solenoid valve 24 to open. After the solenoid valve 24 is opened, the solution inside the reaction vessel 20 will gradually pass through the solenoid valve 24 and the discharge pipe 25 and be collected by the user.

[0112] As the solution inside the reaction vessel 20 is gradually discharged, several floats 34 will gradually move downwards. The downward movement of the floats 34 will drive the material container 21, several ball bearings 35, and the conical toothed ring 43 to move downwards. The downward movement of the material container 21 can slide downwards along the four vertical keys 30 until the solution inside the reaction vessel 20 and the material container 21 is discharged through the solenoid valve 24 and the discharge pipe 25. At this time, the floats 34, the material container 21, the ball bearings 35, and the conical toothed ring 43 will return to their original positions.

[0113] Then the user activates cylinder 31 to extend. Cylinder 31 extends, causing extrusion plate 32 to move downwards into the material container 21. Extrusion plate 32 moves downwards, causing scraper to move downwards into the material container 21. Scraper moves downwards into the material container 21, scraping out the raw material residue on the inner wall of the material container 21 until all the raw material residue inside the material container 21 is concentrated at the bottom of the material container 21. At this time, extrusion plate 32 continues to move downwards, applying pressure to the raw material residue. The raw material residue is under pressure, which is transmitted to reaction vessel 20. The reaction vessel 20 is under pressure, which is transmitted to pressure sensor. When pressure sensor reaches its set maximum pressure sensing value, pressure sensor sends a control signal to controller. After receiving the control signal, controller controls cylinder 31 to retract. The retraction of cylinder 31 causes extrusion plate 32 to rise, which in turn causes scraper to rise, until cylinder 31 returns to its original position. This process squeezes out the residual solution from the raw material residue and discharges it from the reaction tank 20 through several holes in the holding tank 21, the solenoid valve 24, and the discharge pipe 25. This completes the recovery of the solution from the raw material residue.

[0114] After the solution recovery of the raw material residue is completed and it is compressed into blocks, the user can remove the cap 26 from the reaction vessel 20 again, clean out the raw material residue, and clean the reaction vessel 20 and the material container 21. Then, close the solenoid valve 24 and reinstall the cap 26 on the reaction vessel 20. This completes the entire process of solution production.

[0115] The above embodiments are only some embodiments of the present invention, and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention.
