Description

Technical Field

[0001] The invention relates to the technical field of ultrafiltration, in particular to ultrafiltration equipment for hydrogen peroxide care solution and an ultrafiltration process thereof. Background Art

[0002] Hydrogen peroxide care solution ultrafiltration equipment is used to filter and purify hydrogen peroxide care solution. It primarily utilizes ultrafiltration technology to achieve specific separation and purification functions. Ultrafiltration is a membrane separation technology that uses a pressure differential across the membrane as a driving force and utilizes the principle of mechanical sieving to separate solutions. The membrane has a porous asymmetric structure with tiny pores that can retain particles and impurities within a certain size range. In the treatment of hydrogen peroxide care solution, this equipment utilizes the properties of the ultrafiltration membrane to allow small molecules (such as water and dissolved inorganic salts) in the hydrogen peroxide care solution to pass through while retaining larger molecules (such as potential impurities, proteins, and microorganisms), thereby achieving separation and purification.

[0003] Existing ultrafiltration equipment for hydrogen peroxide care solutions has significant shortcomings. Among them, the lack of a stirring device presents numerous problems. First, without stirring, particulate matter in the hydrogen peroxide care solution easily settles and aggregates in a static state. Over time, these particles clog the pores of the ultrafiltration components, significantly reducing ultrafiltration efficiency. Clogged ultrafiltration components not only significantly reduce filtration effectiveness but also increase operating pressure, requiring more energy to maintain operation, thereby increasing production costs. Frequent clogging shortens the lifespan of the ultrafiltration components, leading to more frequent component replacements and further increasing maintenance costs. Furthermore, the lack of a stirring device can lead to uneven distribution of the care solution's composition. During the ultrafiltration process, the concentration of the liquid can vary across different areas, severely impacting the consistency and stability of the ultrafiltration process. For example, the care solution in some areas may be fully filtered, while the liquid in others still contains significant impurities. This unevenness significantly reduces product quality, making it difficult to meet high production standards. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a hydrogen peroxide care solution ultrafiltration device and an ultrafiltration process thereof.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: The hydrogen peroxide care liquid ultrafiltration device comprises an upper box body and a lower box body, wherein a reciprocating screw is rotatably provided on the upper box body through a support mechanism, a movable plate is threadedly sleeved on the reciprocating screw, a piston plate and a partition are provided inside the upper box body, a liquid inlet pipe extending to the interior is provided on the upper box body, the piston plate is connected to the movable plate through a push rod, a stirring fan blade is provided on the piston plate through a rotating rod, a transmission shaft is provided on the movable plate through a support plate, a rack rack is provided on the upper box body, the transmission shaft is connected to the rack rack through an active mechanism, and the transmission shaft is connected to the rotating rod through a transmission mechanism; An adjustment motor is provided on the upper box body through a first fixed plate, a turntable is installed on the output shaft of the adjustment motor, two connecting shafts are rotatably provided on the turntable, and an ultrafiltration component located between the upper box body and the lower box body is fixed on the two connecting shafts. Mounting rings are provided on both the upper box body and the lower box body through a second fixed plate, and the connecting shafts are connected to the mounting rings through a flip mechanism.

[0006] Preferably, the support mechanism includes a support frame installed on the upper box body and connected to the reciprocating screw, and a reciprocating motor connected to the reciprocating screw is provided on the support frame.

[0007] Preferably, the active mechanism comprises a driving gear mounted on the transmission shaft, and the driving gear is engaged with the rack.

[0008] Preferably, the transmission mechanism includes a transmission gear mounted on a transmission shaft, and the rotating rod is provided with a linkage gear meshing with the transmission gear.

[0009] Preferably, the flip mechanism includes a flip gear fixedly mounted on the connecting shaft, and both upper and lower surfaces of the mounting rings are provided with arc-shaped racks corresponding to the flip gear.

[0010] Preferably, a first valve is provided inside the liquid inlet pipe, and a second valve is provided in the opening of the partition, and both the first valve and the second valve are one-way valves.

[0011] The ultrafiltration process of hydrogen peroxide care solution includes the following steps: S1. Preparation phase: Check that all components of the hydrogen peroxide care solution ultrafiltration equipment are functioning properly. Ensure that the support frame firmly supports the reciprocating screw and that the reciprocating motor is connected properly and can be started. Check that the driving gear on the drive shaft is meshing well with the rack rack, and that the transmission gear and the linkage gear on the rotating rod are properly matched. Check the first valve in the inlet pipe and the second valve in the partition opening to ensure that both check valves are functioning properly. Prepare the hydrogen peroxide care solution to be ultrafiltered and place it in a location that is convenient for delivery to the inlet pipe. S2, feeding and stirring stage: The reciprocating motor is started, driving the reciprocating screw to rotate, causing the movable plate threaded on the reciprocating screw to move up and down. The movable plate drives the piston plate up and down via the push rod. As the piston plate moves up and down, the hydrogen peroxide care solution is drawn into the upper box. The stirring blades on the rotating rod rotate, driven by the piston plate, stirring and mixing the hydrogen peroxide care solution entering the upper box, which is then filtered through the ultrafiltration component and discharged through the lower box; S3, Ultrafiltration Component Adjustment Stage: When the equipment is not in use, start the adjustment motor and the turntable on the motor output shaft begins to rotate. The two connecting shafts on the turntable drive the two ultrafiltration components to rotate, and the rotation of the two ultrafiltration components can also complete the position exchange. During the position exchange process, the two ultrafiltration components will also flip, and this flipping ensures that the filter surface of the ultrafiltration component on the outside faces downward.

[0012] Beneficial effects of the present invention: 1. Through the cooperation of reciprocating screw, movable plate, piston plate and stirring blades, the automatic suction and extrusion discharge of hydrogen peroxide care liquid is realized. At the same time, the stirring blades stir to prevent particle precipitation and aggregation, improve ultrafiltration efficiency and ensure the uniformity of the liquid.

[0013] 2. Two ultrafiltration components are set up. When one needs to be replaced or cleaned, it can be quickly replaced by adjusting the motor and turntable, which does not affect the production progress and improves the continuous operation capability of the equipment.

[0014] 3. During the replacement of the ultrafiltration component, the flip gear cooperates with the arc-shaped rack to flip the ultrafiltration component, which is conducive to the falling and cleaning of impurities, reduces the difficulty of maintenance, and extends the service life of the equipment.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-6 The hydrogen peroxide care liquid ultrafiltration device includes an upper box body 1 and a lower box body 2. A reciprocating screw 7 is rotatably provided on the upper box body 1 through a support mechanism. A movable plate 8 is threadedly sleeved on the reciprocating screw 7. A piston plate 18 and a partition 20 are provided inside the upper box body 1. The upper box body 1 is provided with a liquid inlet pipe 4 extending to the interior. The piston plate 18 is connected to the movable plate 8 through a push rod 10. A stirring fan 19 is provided on the piston plate 18 through a rotating rod 11. A transmission shaft 14 is provided on the movable plate 8 through a support plate 13. A rack rack 12 is provided on the upper box body 1. The transmission shaft 14 is connected to the rack rack 12 through an active mechanism, and the transmission shaft 14 is connected to the rotating rod 11 through a transmission mechanism. An adjustment motor 22 is provided on the upper box body 1 through a first fixed plate 21, and a turntable 23 is installed on the output shaft of the adjustment motor 22. Two connecting shafts 24 are rotatably provided on the turntable 23. The two connecting shafts 24 are fixed with an ultrafiltration component 3 located between the upper box body 1 and the lower box body 2. A mounting ring 26 is provided on both the upper box body 1 and the lower box body 2 through a second fixed plate 25, and the connecting shaft 24 is connected to the mounting ring 26 through a flip mechanism.

[0019] The support mechanism includes a support frame 5 mounted on the upper housing 1 and connected to the reciprocating screw 7. The support frame 5 is provided with a reciprocating motor 6 connected to the reciprocating screw 7. The support frame 5 effectively supports the reciprocating screw 7. The reciprocating motor 6 is the power device of the reciprocating screw 7. Its external exposure is convenient for heat dissipation and easy maintenance.

[0020] The active mechanism comprises a driving gear 15 mounted on the transmission shaft 14, and the driving gear 15 is engaged with the rack 12. As shown in the figure, the driving gear 15 is a circular gear.

[0021] The transmission mechanism includes a transmission gear 16 mounted on the transmission shaft 14, and a linkage gear 17 meshing with the transmission gear 16 is provided on the rotating rod 11. As shown in the figure, the transmission gear 16 and the linkage gear 17 are both bevel gears, and the relationship between the two is vertical meshing.

[0022] The flip mechanism includes a flip gear 27 fixedly mounted on the connecting shaft 24. Both upper and lower mounting rings 26 are equipped with arcuate racks corresponding to the flip gear 27. The arcuate rack on the upper mounting ring 26 is located on its bottom wall, while the arcuate rack on the lower mounting ring 26 is located on its upper end surface. The upper and lower arcuate racks are designed to be staggered.

[0023] In the initial state, one ultrafiltration assembly 3 is in use and the other ultrafiltration assembly 3 is in standby. Only when the used ultrafiltration assembly 3 is completely separated from the upper housing 1 and the lower housing 2 will the flip gear 27 meet or even mesh with the arc-shaped rack. Similarly, only when the standby ultrafiltration assembly 3 moves and does not enter between the upper housing 1 and the lower housing 2 will the flip gear 27 meet or even mesh with the arc-shaped rack.

[0024] A first valve is provided inside the liquid inlet pipe 4, and a second valve is provided in the opening of the partition plate 20. Both the first valve and the second valve are one-way valves. The design of the first valve and the second valve as one-way valves ensures the one-way flow of liquid.

[0025] When the present invention is in use, the liquid inlet pipe 4 is connected to the holding device for holding the hydrogen peroxide care solution. When the ultrafiltration treatment is performed, the reciprocating motor 6 is started, and the reciprocating motor 6 can drive the reciprocating screw 7 to rotate. When the reciprocating screw 7 rotates, the movable plate 8 can move up and down along the reciprocating screw 7. At this time, the piston plate 18 can be driven by the push rod 10 to move back and forth between the upper box body 1 and the lower box body 2. When the piston plate 18 moves up, the hydrogen peroxide care solution can be sucked in by relying on the liquid inlet pipe 4. When the piston plate 18 descends, it can be sent into the lower box body 2 by relying on the partition 20, and can be processed by the ultrafiltration component 3.

[0026] At the same time, when the movable plate 8 moves, the driving gear 15 provided thereon will rotate under the action of the rack 12. The driving gear 15 can drive the transmission gear 16 to rotate with the help of the transmission shaft 14. The transmission gear 16 can cooperate with the linkage gear 17 to drive the rotating rod 11 to rotate. The rotating rod 11 can drive the stirring blade 19 to rotate, so that the hydrogen peroxide care solution is continuously mixed and flowed while being squeezed. This helps prevent particulate matter in the hydrogen peroxide care solution from settling or gathering in a certain area, thereby reducing the possibility of clogging of the ultrafiltration component 3. The continuous flow allows the ultrafiltration components 3 in different areas to have the opportunity to contact the ultrafiltration component 3, improving the uniformity of the entire process and ensuring stable and efficient efficiency.

[0027] In the present invention, two ultrafiltration components 3 are provided as shown in the figure, which can be replaced in time. The replacement steps are: start the adjustment motor 22 to drive the turntable 23 to rotate, and the turntable 23 will cooperate with the connecting shaft 24 to drive the two ultrafiltration components 3 to rotate, thereby completing the replacement.

[0028] During this process, since arc-shaped racks are provided on both the upper and lower mounting rings 26, the overall state is as follows: the used ultrafiltration component 3 is rotated and removed. After removal, the flip gear 27 corresponding to the ultrafiltration component 3 will engage with the arc-shaped rack on the lower mounting ring 26. During the subsequent rotation of the turntable 23, the flip gear 27, under the action of the arc-shaped rack, can drive the connecting shaft 24 and the ultrafiltration component 3 to flip so that the filtering side faces downward, which is conducive to the falling and cleaning of impurities.

[0029] The ultrafiltration component 3, which is initially external and with the filtering side facing downward, will rotate with the turntable 23 and enter between the upper box body 1 and the lower box body 2 for use. During the rotation, the flip gear 27 is flipped under the action of the arc-shaped rack on the upper mounting ring 26 so that the filtering side faces upward, thereby playing a filtering role in normal use.

[0030] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
