Description

Technical Field

[0001] This invention relates to the field of graphene MBR membrane fiber production technology, and in particular to a graphene MBR membrane fiber production equipment. Background Technology

[0002] With water scarcity and increasingly stringent environmental protection requirements, membrane bioreactors (MBRs) are widely used in wastewater treatment. However, traditional MBR membrane fibers made of polyvinylidene fluoride (PVDF) and polysulfone have limitations, such as low membrane flux and susceptibility to fouling, resulting in high operation and maintenance costs and frequent downtime.

[0003] At this juncture, the emergence of graphene brought a turning point. It possesses a unique two-dimensional structure, excellent mechanical properties, high electrical conductivity, and superior chemical stability. Introducing graphene into MBR membrane fibers promises to enhance the membrane's mechanical strength, enabling it to withstand higher pressures and tensile stresses, thus reducing the risk of fiber breakage; its conductivity can inhibit microbial adhesion, mitigating biofouling; and its chemical stability resists the erosion of chemicals in wastewater, extending membrane lifespan.

[0004] In existing technologies, during the preparation of solutions for graphene MBR membrane fiber production, a large number of bubbles appear during the mixing process. If these bubbles are not eliminated in time, they will affect the quality of the final solution product. Therefore, to solve the above problem, we provide a graphene MBR membrane fiber production equipment. Summary of the Invention

[0005] The present invention addresses the technical problem of how to quickly and efficiently eliminate bubbles generated during solution mixing, and provides a graphene MBR membrane fiber production equipment.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a graphene MBR membrane fiber production equipment, including: a centrifugal filtration and mixing device, a defoaming device, a shock absorption device, a controller, and a workbench.

[0007] The workbench is located on the ground and has an internal cavity. A centrifugal filtration and mixing unit is mounted on the workbench for separating the solution from the residue. An antifoaming device is mounted on the centrifugal filtration and mixing unit to eliminate bubbles generated during raw material mixing. A vibration damping device is mounted on the workbench to reduce vibration in the centrifugal filtration and mixing unit. A controller is located to the side of the workbench and on the ground, and is electrically connected to the centrifugal filtration and mixing unit and the vibration damping device.

[0008] Centrifugal filtration devices separate solutions from residues. Defoaming devices eliminate bubbles generated during raw material mixing. Shock-absorbing devices provide support and damping during centrifugal operation.

[0009] Furthermore, the centrifugal filtration mixing device includes: a sealed barrel, a filter barrel, a sealed cover, a drive motor, a solenoid valve, a housing, and a discharge pipe.

[0010] The housing extends through the top of the worktable, and the side of the housing is slidably connected to the top of the worktable, with the sliding direction set vertically.

[0011] The sealing barrel is vertically positioned above the housing, and its outer bottom surface is fixedly connected to the top surface of the housing.

[0012] The sealing cap is positioned above the sealing barrel and is connected to the sealing barrel.

[0013] The rotating shaft of the drive motor passes through the top of the housing. The outer shell of the drive motor is fixedly connected to the inner bottom surface of the housing. The rotating shaft of the drive motor is rotatably connected to the top of the housing. Its rotation axis coincides with the axis of the sealed barrel. The drive motor is also electrically connected to the controller. The drive motor is set as a three-phase asynchronous motor.

[0014] The filter barrel extends vertically through the bottom of the sealed barrel and is located above the drive motor. Its axis coincides with the axis of the sealed barrel. The outer bottom surface of the filter barrel is fixedly connected to the rotating shaft of the drive motor. The outer side surface of the filter barrel is rotatably connected to the bottom of the sealed barrel, and the rotating axis coincides with its own axis. Several holes are staggered on the side of the filter barrel, and several holes communicate with the interior of the sealed barrel.

[0015] The discharge pipe is an L-shaped pipe. One end of the discharge pipe passes through the side of the shell and the bottom of the sealed barrel and communicates with the inside of the sealed barrel. The other end communicates with the outside. The discharge pipe is fixedly connected to the side of the shell and sealed and fixedly connected to the bottom of the sealed barrel.

[0016] The solenoid valve is located at the other end of the discharge pipe and is electrically connected to the controller.

[0017] Furthermore, a first handle is provided on the top of the sealing cap, and the sealing cap is threadedly connected to the sealing barrel.

[0018] The drive motor is a Y160M-2 three-phase asynchronous motor.

[0019] When a user wants to produce a graphene MBR membrane fiber solution, the user first holds the first handle and then rotates the first handle. The rotation of the first handle causes the sealing cap to rotate and rise until the sealing cap is completely removed from the sealing tank.

[0020] Then, the user puts the solid and liquid raw materials required for production into the filter tank. The solid raw materials will remain inside the filter tank, while the liquid raw materials will enter the sealed tank through several holes in the filter tank until the liquid level in the sealed tank is the same as the liquid level in the filter tank.

[0021] Then the user holds the first handle, puts the sealing cap on the sealing barrel, and then rotates the first handle. The rotation of the first handle causes the sealing cap to rotate until the sealing cap is tightly connected to the sealing barrel.

[0022] Then the user controls the drive motor to start slowly and the ultrasonic generator to start. The ultrasonic generator emits high-frequency vibrations, which promotes rapid mixing of the liquid and solid materials in the filter tank.

[0023] The drive motor starts slowly, causing the filter barrel to rotate. The rotation of the filter barrel causes the liquid and solid raw materials inside the filter barrel to rotate, thus completing the mixing of the liquid and solid raw materials.

[0024] Once the solution in the sealed container and filter container has been processed, the solenoid valve opens, and the drive motor rotates at high speed. The high-speed rotation of the drive motor causes the filter container to rotate at high speed. The centrifugal force generated by the high-speed rotation of the filter container throws the solid residue inside the filter container onto its inner wall. The solution then leaves the filter container through several holes and enters the sealed container. The solution inside the sealed container is discharged through the outlet pipe and solenoid valve and collected. Once the solution inside the sealed container has been completely discharged, the solenoid valve, drive motor, and ultrasonic generator are shut off. This completes the centrifugal filtration separation of the solution and solid residue, and the centralized collection of the solution.

[0025] Furthermore, the defoaming device includes: a connecting rod, a first disc, a second disc, two first balls, two vertical rods, and two first vertical bars.

[0026] The connecting rod is vertically installed inside the filter barrel, coinciding with the axis of the filter barrel, and the top of the connecting rod is fixedly connected to the bottom surface of the sealing cover.

[0027] The first disc is horizontally positioned inside the filter barrel, below the connecting rod, with its center coinciding with the axis of the filter barrel. The top surface of the first disc is fixedly connected to the bottom end of the connecting rod, and the bottom surface of the first disc has wavy protrusions.

[0028] Two first vertical bars are respectively installed inside the filter barrel, below the first disc. The sides of the two first vertical bars are fixedly connected to the inner wall of the filter barrel, and the bottom of the two first vertical bars are respectively fixed with a first horizontal plate.

[0029] The second disc is horizontally positioned inside the filter barrel, below the first disc, with its center coinciding with the axis of the filter barrel. The side of the second disc is slidably connected to two first vertical strips, with the sliding direction set vertically. Several first spikes are vertically arranged at the bottom of the second disc, and a second handle is also provided at the top of the second disc.

[0030] Two vertical rods are respectively set between the first disk and the second disk, and the bottom ends of the two vertical rods are fixedly connected to the top surface of the second disk. The two vertical rods correspond to any straight line containing the diameter of the first disk.

[0031] Two first ball bearings are respectively positioned on the top of the two vertical rods, and the two first ball bearings are also in contact with several wavy protrusions on the bottom surface of the first disc.

[0032] Furthermore, the defoaming device also includes a buoyancy ring.

[0033] The connecting rod is a square telescopic rod. The buoyancy ring is located inside the filter barrel, below the second disc, with its axis coinciding with the axis of the second disc. The top surface of the buoyancy ring is fixedly connected to the bottom surface of the second disc and is located outside several first spikes.

[0034] Furthermore, the defoaming device also includes: two floats, several second ball bearings, and two second vertical strips.

[0035] Two second vertical strips are located between the filter barrel and the sealing barrel, respectively. The sides of the two second vertical strips are fixedly connected to the outer side of the filter barrel, and the bottom ends are fixed with second horizontal plates.

[0036] Two floats are horizontally arranged inside the sealed barrel and on the outside of the filter barrel. One side of each float is slidably connected to two second vertical bars, with the sliding direction set vertically. The two floats are on the same horizontal line, and each side is horizontally provided with several second spikes.

[0037] Several second balls are respectively disposed on the side of the two floats away from the filter barrel, and several second balls are respectively in contact with the inner wall of the sealed barrel.

[0038] The rising liquid level in the sealed container will cause the two floats to rise, and the rising of the two floats will cause several rolling beads and several second spikes to rise, until the liquid level in the sealed container stops rising.

[0039] When the two first vertical bars rotate, they drive the second disk to rotate. The rotation of the second disk drives the two vertical rods, several first spikes, and buoyancy rings to rotate. The rotation of the two vertical rods drives the two first ball bearings to rotate. The two first ball bearings roll on several wavy protrusions on the first disk, thus receiving a periodically changing downward pressure from the wavy protrusions. This, combined with the buoyancy rings, causes the two first ball bearings to drive the two vertical rods to move up and down reciprocally. The reciprocating up and down movement of the two vertical rods causes the second disk to slide up and down along the two first vertical bars. The reciprocating up and down movement of the second disk causes the several first spikes and buoyancy rings to move up and down reciprocally. This allows the several first spikes to pierce the larger and more stubborn bubbles generated on the liquid surface.

[0040] When the two second vertical bars rotate, they drive the two floats to rotate, which in turn drives several second ball bearings and several second spikes to rotate. The ball bearings rotate radially along the inner wall of the sealed container and its axis. The spikes rotate and pop any air bubbles that appear on the liquid surface inside the sealed container, thus eliminating the air bubbles.

[0041] When there is no liquid in the filter tank, the second disc will be blocked by the first horizontal plate of the two first vertical bars, preventing the second disc from detaching from the two first vertical bars.

[0042] When there is no liquid in the reaction vessel, the two floats will be blocked by the second horizontal plates of the two second vertical bars, preventing the two floats from detaching from the two second vertical bars.

[0043] Furthermore, the shock absorption device includes: several shock absorption springs, an ultrasonic generator, several buffer columns, several support cylinders, several buffer plugs, and several support springs.

[0044] The bottom of the ultrasonic generator is fixedly connected to the inner bottom surface of the filter barrel, and the ultrasonic generator is also electrically connected to the controller.

[0045] Several support cylinders are vertically arranged inside the cavity, located below the shell, and the bottom ends of the support cylinders are fixedly connected to the inner bottom surface of the workbench.

[0046] Several buffer plugs are respectively installed inside several support cylinders, and their sides are slidably connected to the inner walls of the support cylinders, with the sliding direction set vertically.

[0047] Several buffer columns are vertically installed inside several support cylinders, above several buffer plugs. The tops of the buffer columns are fixedly connected to the bottom surface of the shell, and the bottoms are fixedly connected to the top surfaces of the buffer plugs.

[0048] Several shock-absorbing springs are vertically sleeved on several buffer columns, with their bottom ends fixedly connected to the top surfaces of several buffer plugs, and their top ends fixedly connected to the bottom surfaces of the housing.

[0049] Several support springs are vertically arranged inside several support cylinders, below several buffer plugs. The top ends of the support springs are fixedly connected to the bottom surfaces of the buffer plugs, and the bottom ends are fixedly connected to the inner bottom surface of the worktable.

[0050] As the overall weight of the sealing barrel and filter barrel increases, the outer shell slides downwards. This downward movement causes the sealing barrel, filter barrel, drive motor, and heating rod to move downwards, which in turn causes several damping springs to shorten and several buffer columns to move downwards. The downward movement of the buffer columns causes several buffer plugs to move downwards, which in turn causes several support springs to shorten. This provides support and damping for the sealing barrel and filter barrel as their weight changes.

[0051] When the solution in the sealed container and filter container leaves the sealed container through the discharge pipe and solenoid valve, the weight of the sealed container and filter container decreases. Under the action of several damping springs and several supporting springs, the shell moves upward. This upward movement of the shell drives the sealed container, filter container, drive motor, and heating rod upward. The vibration force on the drive motor and sealed container is transmitted through the shell to the damping springs and buffer columns. The vibration force on the buffer columns is then transmitted through several buffer plugs to the supporting springs. This completes the vibration damping of the shell, filter container, and sealed container.

[0052] Furthermore, it also includes a safety valve. One end of the safety valve extends laterally through the side of the sealed barrel, communicating with the interior of the sealed barrel. The side of the safety valve is sealed and fixedly connected to the side of the sealed barrel. The other end of the safety valve is connected to the exhaust gas treatment equipment through a gas pipe.

[0053] When the pressure inside the sealed container increases to the maximum pressure set by the safety valve, the safety valve will automatically open. The gas inside the sealed container will then pass through the safety valve and pipeline into the waste gas treatment equipment until the pressure inside the sealed container returns to normal, at which point the safety valve will automatically close. This process depressurizes the sealed container and collects some of the harmful gases inside.

[0054] Furthermore, a pressure gauge is installed on the side of the sealed container, with the probe of the pressure gauge extending through the side of the sealed container into the interior of the sealed container.

[0055] After the solution production in the sealed container and filter container is complete, the user should first check if the pressure gauge reading is at normal pressure. If it is, open the solenoid valve and start the motor at high speed. If the pressure gauge reading is high, the user can manually open the safety valve to release pressure inside the sealed container until the pressure gauge reading returns to normal pressure. Then, open the solenoid valve and start the motor at high speed to complete the solution collection.

[0056] Furthermore, it also includes: a heating rod: the heating rod is located on the side of the sealed barrel, and the heating rod is also electrically connected to the controller.

[0057] Users can choose whether to activate the heating rod as needed. Once activated, the heat emitted by the heating rod will be transferred to the solution inside the sealed container, thus heating the solution within the container.

[0058] The beneficial effects of this invention are: 1. This invention comprises a centrifugal filtration and mixing device, a defoaming device, a shock-absorbing device, a controller, and a worktable. The centrifugal filtration device separates the solution from the residue. The defoaming device eliminates bubbles generated during raw material mixing. The shock-absorbing device provides support and damping for the centrifugal device during operation. This working method achieves the technical effect of quickly and efficiently eliminating bubbles generated during solution mixing.

[0059] 2. This invention, by incorporating a buoyancy ring, connecting rod, first disc, second disc, two first ball bearings, two vertical rods, two first vertical bars, two floats, several second ball bearings, and two second vertical bars, achieves the function of eliminating air bubbles generated during solution mixing based on the liquid level.

[0060] 3. This invention achieves support and shock absorption for sealed barrels and filter barrels with varying weights by incorporating several shock-absorbing springs, an ultrasonic generator, several buffer columns, several support cylinders, several buffer plugs, and several support springs.

[0063] 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.

[0064] Please see Figure 1-3 A graphene MBR membrane fiber production equipment includes: a centrifugal filtration and mixing device, a defoaming device, a shock absorption device, a controller, and a workbench 1.

[0065] Workbench 1 is located on the ground and has an internal cavity. A centrifugal filtration and mixing device is mounted on workbench 1 for separating the solution from the residue. An antifoaming device is mounted on the centrifugal filtration and mixing device to eliminate bubbles generated during raw material mixing. A vibration damping device is mounted on workbench 1 to reduce vibration in the centrifugal filtration and mixing device. A controller is located to the side of workbench 1 and on the ground; the controller is electrically connected to the centrifugal filtration and mixing device and the vibration damping device.

[0066] Centrifugal filtration devices separate solutions from residues. Defoaming devices eliminate bubbles generated during raw material mixing. Shock-absorbing devices provide support and damping during centrifugal operation.

[0067] The centrifugal filtration and mixing device includes: a sealed barrel 20, a filter barrel 21, a sealed cover 22, a drive motor 23, a solenoid valve 24, a housing 25, and a discharge pipe 26.

[0068] The housing 25 extends through the top of the worktable 1, and the side of the housing 25 is slidably connected to the top of the worktable 1, with the sliding direction set vertically.

[0069] The sealing barrel 20 is vertically positioned above the housing 25, and the outer bottom surface of the sealing barrel 20 is fixedly connected to the top surface of the housing 25.

[0070] The sealing cap 22 is positioned above the sealing barrel 20 and is connected to the sealing barrel 20.

[0071] The rotating shaft of the drive motor 23 passes through the top of the housing 25. The outer shell of the drive motor 23 is fixedly connected to the inner bottom surface of the housing 25. The rotating shaft of the drive motor 23 is rotatably connected to the top of the housing 25. Its rotation axis coincides with the axis of the sealed barrel 20. The drive motor 23 is also electrically connected to the controller. The drive motor 23 is set as a three-phase asynchronous motor.

[0072] The filter barrel 21 extends vertically through the bottom of the sealing barrel 20 and is located above the drive motor 23. Its axis coincides with the axis of the sealing barrel 20. The outer bottom surface of the filter barrel 21 is fixedly connected to the rotating shaft of the drive motor 23. The outer side surface of the filter barrel 21 is rotatably connected to the bottom of the sealing barrel 20, and the rotating axis coincides with its own axis. Several holes are staggered on the side of the filter barrel 21, and several holes communicate with the interior of the sealing barrel 20.

[0073] The discharge pipe 26 is an L-shaped pipe. One end of the discharge pipe 26 passes through the side of the housing 25 and the bottom of the sealed barrel 20 and communicates with the inside of the sealed barrel 20. The other end communicates with the outside. The discharge pipe 26 is fixedly connected to the side of the housing 25 and is sealed and fixedly connected to the bottom of the sealed barrel 20.

[0074] Solenoid valve 24 is located at the other end of discharge pipe 26 and is electrically connected to controller.

[0075] The top of the sealing cover 22 is provided with a first handle, and the sealing cover 22 is threadedly connected to the sealing barrel 20.

[0076] The drive motor 23 is a Y160M-2 three-phase asynchronous motor.

[0077] When a user wants to produce a graphene MBR membrane fiber solution, the user first holds the first handle and then rotates the first handle. The rotation of the first handle causes the sealing cover 22 to rotate and rise until the sealing cover 22 is completely separated from the sealing barrel 20.

[0078] Then the user puts the solid and liquid raw materials required for production into the filter tank 21. The solid raw materials will remain inside the filter tank 21, while the liquid raw materials will enter the sealed tank 20 through several holes in the filter tank 21 until the liquid level in the sealed tank 20 is the same as the liquid level in the filter tank 21.

[0079] Then the user holds the first handle and puts the sealing cap 22 on the sealing barrel 20, and then rotates the first handle. The rotation of the first handle causes the sealing cap 22 to rotate until the sealing cap 22 is tightly connected to the sealing barrel 20.

[0080] Then the user controls the drive motor 23 to start slowly and the ultrasonic generator 41 to start. The ultrasonic generator 41 can emit high-frequency vibrations, which promotes the rapid mixing of liquid and solid raw materials in the filter tank 21.

[0081] The drive motor 23 starts slowly, causing the filter barrel 21 to rotate. The rotation of the filter barrel 21 causes the liquid and solid raw materials inside the filter barrel 21 to rotate. This completes the mixing of the liquid and solid raw materials.

[0082] After the solution in the sealed container 20 and filter container 21 has been processed, the solenoid valve 24 is opened and the drive motor 23 rotates at high speed. The high-speed rotation of the drive motor 23 drives the filter container 21 to rotate at high speed. The centrifugal force generated by the high-speed rotation of the filter container 21 will throw the solid residue inside the filter container 21 onto the inner wall of the filter container 21, and then the solution will leave the filter container 21 through several holes and enter the sealed container 20. The solution inside the sealed container 20 will be discharged from the sealed container 20 through the discharge pipe 26 and the solenoid valve 24 and collected. After the solution inside the sealed container 20 has been completely discharged, the solenoid valve 24, the drive motor 23, and the ultrasonic generator 41 are closed. This completes the centrifugal filtration separation of the solution and solid residue and the centralized collection of the solution.

[0083] The defoaming device includes: a connecting rod 30, a first disc 31, a second disc 32, two first balls 33, two vertical rods 34, and two first vertical bars 36.

[0084] The connecting rod 30 is vertically installed inside the filter barrel 21 and coincides with the axis of the filter barrel 21. The top of the connecting rod 30 is fixedly connected to the bottom surface of the sealing cover 22.

[0085] The first disc 31 is horizontally disposed inside the filter barrel 21, below the connecting rod 30, with its center coinciding with the axis of the filter barrel 21. The top surface of the first disc 31 is fixedly connected to the bottom end of the connecting rod 30, and the bottom surface of the first disc 31 is provided with wavy protrusions.

[0086] Two first vertical bars 36 are respectively disposed inside the filter barrel 21, below the first disc 31. The sides of the two first vertical bars 36 are fixedly connected to the inner wall of the filter barrel 21, and the bottom of the two first vertical bars 36 are respectively fixed with a first horizontal plate.

[0087] The second disc 32 is horizontally disposed inside the filter barrel 21, below the first disc 31, with its center coinciding with the axis of the filter barrel 21. The side of the second disc 32 is slidably connected to two first vertical bars 36, with the sliding direction set vertically. Several first spikes are vertically disposed at the bottom of the second disc 32, and a second handle is disposed at the top of the second disc 32.

[0088] Two vertical rods 34 are respectively disposed between the first disk 31 and the second disk 32. The bottom ends of the two vertical rods 34 are fixedly connected to the top surface of the second disk 32. The two vertical rods 34 correspond to any straight line containing the diameter of the first disk 31.

[0089] Two first ball bearings 33 are respectively disposed on the top of the two vertical rods 34, and the two first ball bearings 33 are also in contact with several wavy protrusions on the bottom surface of the first disc 31.

[0090] The defoaming device also includes: buoyancy ring 37.

[0091] The connecting rod 30 is a square telescopic rod. The buoyancy ring 37 is located inside the filter barrel 21, below the second disc 32, with its axis coinciding with the axis of the second disc 32. The top surface of the buoyancy ring 37 is fixedly connected to the bottom surface of the second disc 32 and is located outside several first spikes.

[0092] The defoaming device also includes: two floats 38, several second ball bearings, and two second vertical bars 39.

[0093] Two second vertical strips 39 are respectively located between the filter barrel 21 and the sealing barrel 20. The sides of the two second vertical strips 39 are fixedly connected to the outer side of the filter barrel 21, and the bottom ends are respectively fixed with second horizontal plates.

[0094] Two floats 38 are respectively horizontally arranged inside the sealed barrel 20 and on the outside of the filter barrel 21. One side of each float 38 is slidably connected to two second vertical bars 39, with the sliding direction set vertically. The two floats 38 are on the same horizontal line, and each side is provided with several second spikes horizontally.

[0095] Several second balls are respectively disposed on the side of the two floats 38 away from the filter barrel 21, and several second balls are respectively in contact with the inner wall of the sealed barrel 20.

[0096] The rising liquid level in the sealed container 20 will cause the two floats 38 to rise, and the rising of the two floats 38 will cause several rolling beads and several second spikes to rise until the liquid level in the sealed container 20 stops rising.

[0097] When the two first vertical bars 36 rotate, they drive the second disk 32 to rotate. The rotation of the second disk 32 drives the two vertical rods 34, several first spikes, and buoyancy rings 37 to rotate. The rotation of the two vertical rods 34 drives the two first balls 33 to rotate. The two first balls 33 roll on several wavy protrusions on the first disk 31, thus receiving a periodically changing downward pressure from the wavy protrusions on the first disk 31. Together with the buoyancy rings 37, the two first balls 33 drive the two vertical rods 34 to move up and down reciprocally. The reciprocating up and down movement of the two vertical rods 34 drives the second disk 32 to slide up and down along the two first vertical bars 36. The reciprocating up and down movement of the second disk 32 drives the several first spikes and buoyancy rings 37 to move up and down reciprocally. This allows the several first spikes to pierce the larger and more stubborn bubbles generated on the liquid surface.

[0098] When the two second vertical bars 39 rotate, they drive the two floats 38 to rotate, which in turn drives a number of second ball bearings and a number of second spikes to rotate. The ball bearings rotate radially along the inner wall of the sealed container 20 and along its axis. The spikes rotate and pop any air bubbles that appear on the liquid surface inside the sealed container 20, thus eliminating the air bubbles within the container.

[0099] When there is no liquid in the filter tank 21, the second disc 32 will be blocked by the first horizontal plate of the two first vertical bars 36, preventing the second disc 32 from detaching from the two first vertical bars 36.

[0100] When there is no liquid in the reaction vessel, the two floats 38 will be blocked by the second horizontal plates of the two second vertical bars 39, preventing the two floats 38 from detaching from the two second vertical bars 39.

[0101] The shock absorption device includes: several shock absorption springs 40, an ultrasonic generator 41, several buffer columns 42, several support cylinders 43, several buffer plugs 44, and several support springs 45.

[0102] The bottom end of the ultrasonic generator 41 is fixedly connected to the inner bottom surface of the filter barrel 21, and the ultrasonic generator 41 is also electrically connected to the controller.

[0103] Several support cylinders 43 are vertically arranged inside the cavity, respectively located below the housing 25, and the bottom ends of the support cylinders 43 are fixedly connected to the inner bottom surface of the workbench 1.

[0104] Several buffer plugs 44 are respectively disposed inside several support cylinders 43, and their sides are slidably connected to the inner walls of several support cylinders 43, with the sliding direction being vertical.

[0105] Several buffer columns 42 are vertically arranged inside several support cylinders 43, above several buffer plugs 44. The top ends of the buffer columns 42 are fixedly connected to the bottom surface of the housing 25, and the bottom ends are fixedly connected to the top surface of the buffer plugs 44.

[0106] Several shock-absorbing springs 40 are vertically sleeved on several buffer columns 42, with their bottom ends fixedly connected to the top surfaces of several buffer plugs 44, and their top ends fixedly connected to the bottom surfaces of the housing 25.

[0107] Several support springs 45 are vertically arranged inside several support cylinders 43, below several buffer plugs 44. The top ends of several support springs 45 are fixedly connected to the bottom surfaces of several buffer plugs 44, and the bottom ends are fixedly connected to the inner bottom surface of the worktable 1.

[0108] When the overall weight of the sealed container 20 and the filter container 21 increases, the housing 25 slides downwards. This downward sliding of the housing 25 causes the sealed container 20, the filter container 21, the drive motor 23, and the heating rod 51 to move downwards. This, in turn, causes several damping springs 40 to shorten and several buffer pillars 42 to move downwards. The downward movement of the buffer pillars 42 causes several buffer plugs 44 to move downwards, which in turn causes several support springs 45 to shorten. This provides support and damping for the sealed container 20 and the filter container 21 as their weight changes.

[0109] When the solution in the sealed container 20 and filter container 21 leaves the sealed container 20 through the discharge pipe 26 and solenoid valve 24, the weight of the sealed container 20 and filter container 21 is reduced. The housing 25 moves upward under the action of several damping springs 40 and several supporting springs 45. This upward movement of the housing 25 drives the sealed container 20, filter container 21, drive motor 23, and heating rod 51 to move upward as well. The vibration force experienced by the drive motor 23 and the sealed container 20 is transmitted through the housing 25 to the damping springs 40 and several buffer columns 42. The vibration force experienced by the buffer columns 42 is then transmitted through several buffer plugs 44 to the supporting springs 45. This completes the damping of the housing 25, filter container 21, and sealed container 20.

[0110] It also includes: safety valve 50. One end of safety valve 50 extends laterally through the side of the sealing barrel 20, and safety valve 50 communicates with the interior of the sealing barrel 20. Its side is sealed and fixedly connected to the side of the sealing barrel 20. The other end of safety valve 50 is connected to the exhaust gas treatment equipment through a gas pipe.

[0111] When the internal pressure of the sealed container 20 increases to the maximum pressure set by the safety valve 50, the safety valve 50 will automatically open. The gas inside the sealed container 20 will then pass through the safety valve 50 and the pipeline into the waste gas treatment equipment until the internal pressure of the sealed container 20 returns to normal pressure, at which point the safety valve 50 will automatically close. This completes the depressurization of the sealed container 20 and simultaneously collects some of the harmful gases inside the sealed container 20.

[0112] A pressure gauge is also provided on the side of the sealed container 20, and the probe of the pressure gauge extends through the side of the sealed container 20 into the interior of the sealed container 20.

[0113] After the solution production in the sealed container 20 and filter container 21 is completed, the user should first check whether the pressure gauge reading is at normal pressure. If it is, control the solenoid valve 24 to open and the drive motor 23 to rotate at high speed. If the pressure gauge reading is at high pressure, the user can manually control the safety valve 50 to open, thereby depressurizing the inside of the sealed container 20 until the pressure gauge reading returns to normal pressure. Then, control the solenoid valve 24 to open and the drive motor 23 to start at high speed to complete the collection of the solution.

[0114] It also includes: heating rod 51: heating rod 51 is disposed on the side of the sealed barrel 20, and heating rod 51 is also electrically connected to the controller.

[0115] Users can choose whether to activate the heating rod 51 as needed. Once activated, the heat emitted by the heating rod 51 will be transferred to the solution inside the sealed container 20, thereby heating the solution inside the sealed container 20.

[0116] Work process: When a user wants to produce a graphene MBR membrane fiber solution, the user first holds the first handle and then rotates the first handle. The rotation of the first handle causes the sealing cover 22 to rotate and rise. The rotation and rise of the sealing cover 22 causes the connecting rod 30 to rotate and rise. The rotation and rise of the connecting rod 30 causes the first disc 31 to rotate and rise until the sealing cover 22 is completely detached from the sealing barrel 20.

[0117] Then, grasp the second handle and pull the second disc 32 upward. The rise of the second disc 32 causes several first spikes, buoyancy rings 37, and two vertical rods 34 to rise. The rise of the two vertical rods 34 causes two first balls 33 to rise until the second disc 32 leaves the filter tank 21 and the sealing tank 20.

[0118] The user then feeds both the solid and liquid raw materials required for production into the filter tank 21. The solid raw materials remain inside the filter tank 21, while the liquid raw materials pass through several holes in the filter tank 21 into the sealed tank 20 until the liquid level in the sealed tank 20 is equal to that in the filter tank 21. Simultaneously, the rising liquid level in the sealed tank 20 causes two floats 38 to rise, which in turn causes several rolling beads and several second spikes to rise until the liquid level in the sealed tank 20 stops rising.

[0119] When the overall weight of the sealed container 20 and the filter container 21 increases, the housing 25 slides downwards. This downward sliding of the housing 25 causes the sealed container 20, the filter container 21, the drive motor 23, and the heating rod 51 to move downwards. This, in turn, causes several damping springs 40 to shorten and several buffer pillars 42 to move downwards. The downward movement of the buffer pillars 42 causes several buffer plugs 44 to move downwards, which in turn causes several support springs 45 to shorten. This provides support and damping for the sealed container 20 and the filter container 21 as their weight changes.

[0120] Then the user holds the second handle and installs the second disc 32 on the two first vertical bars 36 of the filter bucket 21. The second disc 32 will slide down along the two first vertical bars 36 under the action of gravity. The downward sliding of the second disc 32 will drive several first spikes, buoyancy rings 37, and two vertical rods 34 to move downward. The downward movement of the two vertical rods 34 will drive the two first balls 33 to move downward until the buoyancy rings 37 contact the liquid surface in the filter bucket 21. After the buoyancy rings 37 are buoyed by the liquid surface, the buoyancy rings 37 will transfer the buoyancy to the second disc 32, and the second disc 32 will stop moving downward.

[0121] The user then grasps the first handle and presses the first disc 31 simultaneously, shortening the connecting rod 30 to its shortest length. The connecting rod 30 and the first disc 31 are then inserted into the filter canister 21, and the sealing cap 22 is fastened onto the sealing canister 20. At this point, the first disc 31, no longer under user pressure, enters the filter canister 21 and moves downwards due to its own gravity, causing the connecting rod 30 to extend. Several wavy protrusions on the first disc 31 contact the two first ball bearings 33, and the buoyancy of the buoyancy ring 37 supports the first disc 31.

[0122] Then the user rotates the first handle, which causes the sealing cover 22 to rotate, which in turn causes the connecting rod 30 to rotate, and the connecting rod 30 to rotate the first disc 31, until the sealing cover 22 and the sealing barrel 20 are tightly connected together.

[0123] Then the user controls the drive motor 23 to start slowly and the ultrasonic generator 41 to start. The ultrasonic generator 41 can emit high-frequency vibrations, which promotes the rapid mixing of liquid and solid raw materials in the filter tank 21.

[0124] The drive motor 23 starts slowly, causing the filter barrel 21 to rotate. The rotation of the filter barrel 21 causes the liquid raw material, solid raw material, and two first vertical bars 36 inside the filter barrel 21 to rotate, and also causes the two second vertical bars 39 to rotate. This completes the mixing of the liquid raw material and the solid raw material.

[0125] When the two first vertical bars 36 rotate, they drive the second disk 32 to rotate. The rotation of the second disk 32 drives the two vertical rods 34, several first spikes, and buoyancy rings 37 to rotate. The rotation of the two vertical rods 34 drives the two first balls 33 to rotate. The two first balls 33 roll on several wavy protrusions on the first disk 31, thus receiving a periodically changing downward pressure from the wavy protrusions on the first disk 31. Together with the buoyancy rings 37, the two first balls 33 drive the two vertical rods 34 to move up and down reciprocally. The reciprocating up and down movement of the two vertical rods 34 drives the second disk 32 to slide up and down along the two first vertical bars 36. The reciprocating up and down movement of the second disk 32 drives the several first spikes and buoyancy rings 37 to move up and down reciprocally. This allows the several first spikes to pierce the larger and more stubborn bubbles generated on the liquid surface.

[0126] When the two second vertical bars 39 rotate, they drive the two floats 38 to rotate, which in turn drives a number of second ball bearings and a number of second spikes to rotate. The ball bearings rotate radially along the inner wall of the sealed container 20 and along its axis. The spikes rotate and pop any air bubbles that appear on the liquid surface inside the sealed container 20, thus eliminating the air bubbles within the container.

[0127] When the internal pressure of the sealed container 20 increases to the maximum pressure set by the safety valve 50, the safety valve 50 will automatically open. The gas inside the sealed container 20 will then pass through the safety valve 50 and the pipeline into the waste gas treatment equipment until the internal pressure of the sealed container 20 returns to normal pressure, at which point the safety valve 50 will automatically close. This completes the depressurization of the sealed container 20 and simultaneously collects some of the harmful gases inside the sealed container 20.

[0128] Users can choose whether to activate the heating rod 51 as needed. Once activated, the heat emitted by the heating rod 51 will be transferred to the solution inside the sealed container 20, thereby heating the solution inside the sealed container 20.

[0129] After the solution in the sealed container 20 and filter container 21 has been processed, the user should first check if the pressure gauge reading is at normal atmospheric pressure. If it is, the solenoid valve 24 will open and the drive motor 23 will rotate at high speed. The high-speed rotation of the drive motor 23 will cause the filter container 21 to rotate at high speed. The centrifugal force generated by the high-speed rotation of the filter container 21 will throw the solid residue inside the filter container 21 onto the inner wall of the filter container 21, and then the solution will leave the filter container 21 through several holes and enter the sealed container 20. The solution inside the sealed container 20 will be discharged from the sealed container 20 through the discharge pipe 26 and the solenoid valve 24 and collected. After the solution inside the sealed container 20 has been completely discharged, the solenoid valve 24, the drive motor 23, and the ultrasonic generator 41 will be closed. The centrifugal filtration separation of the solution and solid residue is completed.

[0130] If the pressure gauge reading is under high pressure, the user can first manually open the safety valve 50 to release the pressure inside the sealed container 20 until the pressure gauge reading returns to normal pressure. Then, the user can control the solenoid valve 24 to open and the drive motor 23 to start at high speed to complete the collection of the solution.

[0131] When the solution in the sealed container 20 and filter container 21 leaves the sealed container 20 through the discharge pipe 26 and solenoid valve 24, the weight of the sealed container 20 and filter container 21 is reduced. The housing 25 moves upward under the action of several damping springs 40 and several supporting springs 45. This upward movement of the housing 25 drives the sealed container 20, filter container 21, drive motor 23, and heating rod 51 to move upward as well. The vibration force experienced by the drive motor 23 and the sealed container 20 is transmitted through the housing 25 to the damping springs 40 and several buffer columns 42. The vibration force experienced by the buffer columns 42 is then transmitted through several buffer plugs 44 to the supporting springs 45. This completes the damping of the housing 25, filter container 21, and sealed container 20.
