Description

Technical Field

[0001] This invention relates to the field of purified water equipment, specifically a purified water equipment and method for toothpaste production. Background Technology

[0002] The main components of toothpaste include abrasives, humectants, foaming agents, binders, and flavorings. These components need to be mixed with water to form a homogeneous paste. Pure water treatment equipment uses a series of processes, including multi-media filtration, activated carbon filtration, softening, reverse osmosis, and EDI, to remove impurities, microorganisms, organic matter, and inorganic matter from the raw water, producing pure water that meets cosmetic production standards. This pure water serves as a solvent during toothpaste preparation, ensuring that all raw materials are fully dissolved and mixed. This results in toothpaste with good stability, homogeneity, and performance, while also helping to guarantee the quality and safety of the toothpaste, preventing problems such as deterioration and discoloration caused by impurities in the water.

[0003] Toothpaste production has extremely high requirements for water quality. This is because water not only acts as a solvent in toothpaste, helping various ingredients to mix evenly, but also directly affects the stability, taste, shelf life, and safety of the toothpaste. If the quality of the water used in production is substandard, it may introduce impurities, microorganisms, heavy metals, and other harmful substances. These substances can not only change the chemical properties of the toothpaste, leading to instability, layering, thinning, and discoloration, affecting the product's appearance and effectiveness, but may also pose a potential threat to consumers' health. In the toothpaste production process, deep treatment of the raw water to meet the high standards required for production is a key step in ensuring toothpaste quality. Pure water treatment equipment plays an indispensable role in this process, which is highly consistent with the concept of "water pollution control and treatment."

[0004] In the water treatment process, the raw water is pumped from the raw water tank into a multi-media filter to reduce the turbidity. The solution then enters an activated carbon filter to remove free chlorine, organic matter, and microorganisms. Next, it enters a precision filter to remove large particles larger than five micrometers. A dosing tank adds chemicals to the solution to effectively eliminate microbial contamination within the system, ensuring water quality stability and purity. A high-pressure pump then pumps the solution into a reverse osmosis system for further treatment. After treatment, it enters an EDI system to efficiently remove ions and dissolved organic matter, achieving water purification and the production of high-purity water. As the water treatment volume increases, the activated carbon in the activated carbon filter needs to be replaced. This requires disassembling the activated carbon filter, removing and replacing the activated carbon, and then reinstalling it. This cumbersome operation also affects the overall water treatment efficiency of the purified water equipment. Summary of the Invention

[0009] As a further embodiment of the present invention: the number of cams and insert rods are both two, and the two insert rods and cams are symmetrically arranged along the vertical central axis of the annular baffle.

[0010] As a further embodiment of the present invention: the blocking unit includes a blocking sleeve disposed on the outside of the limiting guide rod, a docking chamber is installed on the outer wall of the activated carbon filter tank, a blocking pin extending into the interior of the activated carbon filter tank and located above the blocking sleeve is inserted into the docking chamber, an electromagnet is disposed at one end of the blocking pin and located inside the docking chamber, an iron block is installed on the inner wall of the docking chamber and located on one side of the electromagnet, and a telescopic spring connected to the inner wall of the docking chamber is disposed on the outer side of the blocking pin.

[0011] As a further embodiment of the present invention: the electromagnet, the first normally open solenoid valve, and the second normally open solenoid valve are connected in series via wires.

[0012] As a further embodiment of the present invention: the material shaking and spreading component includes a movable ring installed on the outside of the drainage chamber, a spur gear ring installed on the outer wall of the movable ring, a positioning ring provided at the bottom of the movable ring, a support rod connected to the bottom of the inner wall of the activated carbon filter tank installed at the bottom of the positioning ring, a motor installed on one side of the support rod, a half gear meshing with the spur gear ring connected to the output end of the motor, an arc-shaped groove opened inside the movable ring, an extrusion plate slidably connected to the arc-shaped groove provided at the top of the positioning ring, and an arc-shaped spring connected to the inner wall of the arc-shaped groove provided on one side of the extrusion plate.

[0014] As a further aspect of the present invention: a protective cover is provided on the top outer side of the drainage chamber to prevent activated carbon from falling between the half gear and the spur gear ring.

[0015] This invention also discloses a method for preparing purified water for toothpaste production, using the aforementioned purified water equipment for toothpaste production, comprising the following steps:

[0016] S1: The raw water tank is pumped into a multi-media filter by a raw water pump to reduce the turbidity of the raw water. The water then enters the activated carbon filter tank to remove free chlorine, organic matter, and microorganisms from the water.

[0017] S2: The aqueous solution enters the precision filter, which removes large particles larger than five microns. The dosing tank adds chemicals to the aqueous solution to effectively eliminate microbial contamination within the system and ensure water quality stability and purity.

[0018] S3: The aqueous solution is pumped into a multi-stage reverse osmosis membrane for further treatment using a high-pressure pump. After treatment, it enters the EDI system to efficiently remove ions and dissolved organic matter from the water, thereby purifying the water and producing high-purity water.

[0019] S4: When replacing the activated carbon inside the activated carbon filter tank, first use the controller to energize and close the first normally open solenoid valve and the second normally open solenoid valve to prevent the aqueous solution from entering the inside of the connecting sleeve.

[0020] S5: By operating the material changing device, the activated carbon at the bottom of the inner side of the connecting sleeve is unobstructed. Then, the material shaking and spreading device is activated to discharge the used activated carbon from the inside of the connecting sleeve. After that, by operating the material changing device, the bottom of the connecting sleeve is obstructed again. Then, fresh activated carbon is poured into the inside of the connecting sleeve through the feed pipe. During this process, the activated carbon entering the connecting sleeve is moved by the operation of the material shaking and spreading device, so that the inside of the connecting sleeve is filled with activated carbon and the activated carbon is prevented from accumulating in one place inside the connecting sleeve.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By setting up a material changing component and rotating the threaded screw, the threaded sleeve moves downward along the threaded screw, causing the cam to press and guide the movable pin through the guide ring groove. This causes the movable pin to drive the insert rod upward, which in turn causes the insert rod to drive the annular baffle to retract into the connecting sleeve. At this time, a gap will appear between the top of the drainage chamber and the bottom of the connecting sleeve. Then, in conjunction with the operation of the material shaking and spreading component, the activated carbon inside the connecting sleeve falls into the discharge port. After that, it is discharged from the bottom of the discharge port into the activated carbon filter tank. Then, by rotating the threaded screw in the opposite direction, the annular baffle blocks the gap between the connecting sleeve and the drainage chamber. Then, the feed pipe is opened, and the activated carbon is poured into the feed pipe to accumulate inside the connecting sleeve. This allows the activated carbon to fill the inside of the connecting sleeve, thereby improving the efficiency of activated carbon replacement.

[0023] 2. By setting up the material shaking and spreading component and starting the motor, the motor drives the half gear to rotate. When the half gear meshes with the spur gear ring, the half gear pushes the spur gear ring to rotate. At this time, the movable ring squeezes the arc spring through the arc groove, so as to make the drainage chamber and the spur gear swing synchronously. When the half gear separates from the spur gear ring, the movable ring will recover under the action of the elastic restoring force of the arc spring. In this way, the rotation of the half gear can make the movable ring swing back and forth, thereby increasing the flow of activated carbon above the cone filter plate, so that the activated carbon can be quickly discharged from the inside of the connecting sleeve, and at the same time preventing the activated carbon that falls into the connecting sleeve from accumulating in one place.

[0024] 3. By setting up an isolation unit, when the first normally open solenoid valve and the second normally open solenoid valve are de-energized, the aqueous solution enters the inner side of the connecting sleeve through the first normally open solenoid valve and exits the activated carbon filter tank through the second normally open solenoid valve. At this time, the iron block and the electromagnet are separated, and the stop pin blocks the stop sleeve. During this process, the limit guide rod cannot move upward, thus preventing the threaded screw from rotating when the first normally open solenoid valve and the second normally open solenoid valve are not closed. When the first normally open solenoid valve and the second normally open solenoid valve are energized and closed, the electromagnet is energized and generates magnetic force, which causes the electromagnet to move towards the iron block. At this time, the telescopic spring contracts, which allows the stop pin to retract into the docking chamber, thereby removing the block pin from blocking the stop sleeve. This achieves the orderly closing of the first normally open solenoid valve and the second normally open solenoid valve and the movement of the annular baffle. Attached Figure Description

The following describes embodiments of the invention based on its overall structure.

[0037] Please see Figures 1-9In this embodiment of the invention, a purified water device for toothpaste production includes a connecting frame 1. A raw water tank 2 is installed on one side of the connecting frame 1. A multi-media filter 3 is connected to one side of the raw water tank 2. The multi-media filter 3 is connected to an activated carbon filter tank 4 via a pipe. A multi-stage reverse osmosis membrane 5 and a precision filter are connected to one side of the activated carbon filter tank 4 via a high-pressure pump. One end of the multi-stage reverse osmosis membrane 5 is connected to an EDI module. A first normally open solenoid valve 12 is installed on the top inner side of the activated carbon filter tank 4. The bottom end of the first normally open solenoid valve 12 is connected to a feed valve. The bottom of the feeding bin 14 is rotatably connected to a connecting sleeve 15. An L-shaped splicing frame 18 is installed on the outer wall of the connecting sleeve 15. A drainage bin 19 is set at the bottom of the L-shaped splicing frame 18. A drainage pipe 11 connected to an external pipe is set at the bottom of the drainage bin 19. A second normally open solenoid valve 13 is set on the outside of the drainage pipe 11. A material shaking and spreading component is set on the outside of the drainage bin 19. A material changing component is set inside the connecting sleeve 15. An inlet pipe 7 connected to the feeding bin 14 is set on the outside of the activated carbon filter tank 4. A controller 6 is installed at one end of the connecting frame 1.

[0038] In this embodiment: Water from raw water tank 2 is pumped into multi-media filter 3 by a raw water pump to reduce the turbidity of the raw water. The aqueous solution then enters activated carbon filter tank 4 to remove free chlorine, organic matter, and microorganisms. Next, it enters a precision filter to remove large particles larger than five micrometers. A dosing tank adds chemicals to the aqueous solution to effectively eliminate microbial contamination within the system, ensuring water quality stability and purity. Finally, a high-pressure pump pumps the aqueous solution into a multi-stage reverse osmosis membrane 5 for further treatment. After treatment, it enters an EDI system to efficiently remove ions and dissolved organic matter, achieving water purification and the production of high-purity water. The activated carbon filter tank 4... When replacing activated carbon, firstly, the controller 6 is used to energize and close the first normally open solenoid valve 12 and the second normally open solenoid valve 13 to prevent the aqueous solution from entering the inside of the connecting sleeve 15. Then, the material changing device is operated to remove the obstruction of the activated carbon at the bottom of the inside of the connecting sleeve 15. Subsequently, the material shaking and spreading device is activated to discharge the used activated carbon from the inside of the connecting sleeve 15. Then, the material changing device is operated to make the bottom of the connecting sleeve 15 obstructed again. Then, new activated carbon is poured into the inside of the connecting sleeve 15 through the feed pipe 7. During this process, the operation of the material shaking and spreading device is used to move the activated carbon in the connecting sleeve 15, so that the inside of the connecting sleeve 15 is filled with activated carbon and to prevent the activated carbon from accumulating in one place inside the connecting sleeve 15.

[0039] Please refer to this carefully. Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 The material replacement component includes a cavity 16 formed between the outer and inner walls of the connecting sleeve 15. A threaded screw 8 is provided at the top of the activated carbon filter tank 4. A threaded sleeve 9 extending to the inner side of the activated carbon filter tank 4 is movably sleeved on the outer side of the threaded screw 8. A limiting guide rod 39, which is slidably connected to the inner wall of the activated carbon filter tank 4, is provided at the bottom end of the threaded sleeve 9. An outer connecting ring 22 is provided at the bottom end of the limiting guide rod 39. An inner connecting ring 23 is rotatably connected to the inner wall of the outer connecting ring 22 via a bearing. A rack 24 extending into the cavity 16 is inserted into the bottom of 23. A spur gear 25 is rotatably connected to the inside of the cavity 16 via a rotating shaft. The spur gear 25 meshes with the rack 24. A cam 26 is fixedly connected to one end of the spur gear 25. A guide ring groove 29 is provided at one end of the cam 26. A movable pin 27 is slidably connected to the inside of the guide ring groove 29. A rod 28 is connected to one end of the movable pin 27. An annular baffle 21 extending to the bottom of the connecting sleeve 15 is inserted into the bottom of the rod 28.

[0040] The replacement component also includes a discharge port 31 installed on the inner wall of the activated carbon filter tank 4 and located on the outside of the drainage chamber 19. A conical filter plate 17 is provided on the top of the drainage chamber 19, and a barrier unit connected to the limiting guide rod 39 is installed on the outer wall of the activated carbon filter tank 4.

[0041] There are two cams 26 and two insert rods 28, and the two insert rods 28 and the two cams 26 are symmetrically arranged along the vertical central axis of the annular baffle 21.

[0042] In this embodiment: Rotating the threaded screw 8 causes the threaded sleeve 9 to move downwards along the threaded screw 8. The threaded sleeve 9 then pushes the outer connecting ring 22 downwards via the limiting guide rod 39. As the outer connecting ring 22 moves downwards, it drives the inner connecting ring 23 and the rack 24 to move downwards synchronously, causing the rack 24 to rotate the spur gear 25. The cam 26 then rotates along with the spur gear 25, causing the cam 26 to press and guide the movable pin 27 through the guide ring groove 29. This causes the movable pin 27 to drive the insert rod 28 upwards, allowing the insert rod 28 to retract the annular baffle 21 into the connecting sleeve 15. A gap then appears between the top of the drainage chamber 19 and the bottom of the connecting sleeve 15. Subsequently, in conjunction with the operation of the material shaking and spreading component, the activated carbon inside the connecting sleeve 15 falls into the discharge port 31. The activated carbon filter tank 4 is then discharged from the bottom of the discharge port 31. Subsequently, the annular baffle 21 is blocked by rotating the threaded screw 8 in the opposite direction to block the gap between the connecting sleeve 15 and the drainage chamber 19. Then, the feed pipe 7 is opened, and activated carbon is poured into the feed pipe 7 to make the activated carbon accumulate inside the connecting sleeve 15. This allows the activated carbon to fill the inside of the connecting sleeve 15, thereby improving the efficiency of activated carbon replacement. Then, the first normally open solenoid valve 12 and the second normally open solenoid valve 13 are opened. At this time, the aqueous solution entering the activated carbon filter tank 4 will fall into the inside of the connecting sleeve 15 through the first normally open solenoid valve 12. When the aqueous solution passes through the activated carbon inside the connecting sleeve 15, the aqueous solution is treated by the activated carbon. The treated aqueous solution is discharged through the conical filter plate 17, the drainage chamber 19, the drain pipe 11, and the second normally open solenoid valve 13.

[0043] Please refer to this carefully. Figure 2 , Figure 8 , Figure 9 The blocking unit includes a blocking sleeve 40 disposed outside the limiting guide rod 39. A docking chamber 10 is installed on the outer wall of the activated carbon filter tank 4. A blocking pin 41 extending into the interior of the activated carbon filter tank 4 and located above the blocking sleeve 40 is inserted into the docking chamber 10. An electromagnet 43 located inside the docking chamber 10 is provided at one end of the blocking pin 41. An iron block 42 located on one side of the electromagnet 43 is installed on the inner wall of the docking chamber 10. A telescopic spring 44 connected to the inner wall of the docking chamber 10 is provided on the outer side of the blocking pin 41.

[0044] Among them, the electromagnet 43, the first normally open solenoid valve 12, and the second normally open solenoid valve 13 are connected in series by wires.

[0045] In this embodiment: when the first normally open solenoid valve 12 and the second normally open solenoid valve 13 are de-energized, the aqueous solution enters the inner side of the connecting sleeve 15 through the first normally open solenoid valve 12, and simultaneously exits the activated carbon filter tank 4 through the second normally open solenoid valve 13. At this time, the iron block 42 and the electromagnet 43 are separated, and the stop pin 41 blocks the stop sleeve 40. During this process, the limit guide rod 39 cannot move upward, thus preventing the first normally open solenoid valve 12 and the second normally open solenoid valve from not being closed. When the threaded screw 8 is rotated in case 13, the electromagnet 43 is energized and generates magnetic force when the first normally open solenoid valve 12 and the second normally open solenoid valve 13 are closed. This causes the electromagnet 43 to move toward the iron block 42. At this time, the telescopic spring 44 retracts, which allows the stop pin 41 to retract into the inner side of the docking chamber 10. This causes the stop pin 41 to lose its obstruction of the stop sleeve 40, thereby realizing the orderly closing of the first normally open solenoid valve 12 and the second normally open solenoid valve 13 and the movement of the annular baffle 21.

[0046] Please refer to this carefully. Figure 3 , Figure 5 , Figure 6 The material spreading component includes a movable ring 34 installed on the outside of the drainage chamber 19. A spur gear ring 35 is installed on the outer wall of the movable ring 34. A positioning ring 33 is provided at the bottom of the movable ring 34. A support rod 30 connected to the bottom of the inner wall of the activated carbon filter tank 4 is installed at the bottom of the positioning ring 33. A motor 20 is installed on one side of the support rod 30. A half gear 32 meshing with the spur gear ring 35 is connected to the output end of the motor 20. An arc groove 36 is opened inside the movable ring 34. A pressing plate 37 slidably connected to the arc groove 36 is provided at the top of the positioning ring 33. An arc spring 38 connected to the inner wall of the arc groove 36 is provided on one side of the pressing plate 37.

[0047] The top edge of the positioning ring 33 is rotatably connected to the movable ring 34 via a bearing, and a protective cover is provided on the top outer side of the drainage chamber 19 to prevent activated carbon from falling between the half gear 32 and the spur gear ring 35.

[0048] In this embodiment: the motor 20 is started, which drives the half gear 32 to rotate. When the half gear 32 meshes with the spur gear ring 35, the half gear 32 pushes the spur gear ring 35 to rotate. At this time, the movable ring 34 squeezes the arc spring 38 through the arc groove 36, so that the drainage chamber 19 and the spur gear 25 swing synchronously. When the half gear 32 separates from the spur gear ring 35, the movable ring 34 will recover under the elastic restoring force of the arc spring 38. In this way, the rotation of the half gear 32 can make the movable ring 34 swing back and forth, thereby increasing the fluidity of the activated carbon above the conical filter plate 17, so that the activated carbon can be quickly discharged from the inside of the connecting sleeve 15, and at the same time, it can prevent the activated carbon that falls into the connecting sleeve 15 from accumulating in one place.

[0049] The following describes a method for preparing purified water for toothpaste production, based on the aforementioned purified water equipment for toothpaste generation, specifically including the following steps:

[0050] S1: The raw water tank 2 is pumped into the multi-media filter 3 by the raw water pump. The turbidity of the raw water is reduced by the multi-media filter 3. Then the water solution enters the activated carbon filter tank 4 and removes free chlorine, organic matter and microorganisms from the water by the activated carbon filter tank 4.

[0051] S2: The aqueous solution enters the precision filter, which removes large particles larger than five microns. The dosing tank adds chemicals to the aqueous solution to effectively eliminate microbial contamination within the system and ensure water quality stability and purity.

[0052] S3: The aqueous solution is pumped into the multi-stage reverse osmosis membrane 5 by a high-pressure pump for further treatment. After treatment, it enters the EDI system to efficiently remove ions and dissolved organic matter from the water, thereby purifying the water and producing high-purity water.

[0053] S4: When replacing the activated carbon inside the activated carbon filter tank 4, first, the first normally open solenoid valve 12 and the second normally open solenoid valve 13 are energized and closed by operating the controller 6 to prevent the aqueous solution from entering the inner side of the connecting sleeve 15. When the first normally open solenoid valve 12 and the second normally open solenoid valve 13 are de-energized, the aqueous solution enters the inner side of the connecting sleeve 15 through the first normally open solenoid valve 12, and is discharged from the activated carbon filter tank 4 through the second normally open solenoid valve 13. At this time, the iron block 42 and the electromagnet 43 are separated, and the stop pin 41 blocks the stop sleeve 40. During this process, the limit guide... Rod 39 cannot move upwards, thus preventing the screw 8 from rotating if the first normally open solenoid valve 12 and the second normally open solenoid valve 13 are not closed. When the first normally open solenoid valve 12 and the second normally open solenoid valve 13 are energized and closed, electromagnet 43 is energized and generates magnetic force, thereby causing electromagnet 43 to move towards iron block 42. At this time, extension spring 44 retracts, so that the stop pin 41 retracts into the docking chamber 10, thereby causing the stop pin 41 to lose its obstruction of stop sleeve 40, thus realizing the orderly closing of the first normally open solenoid valve 12 and the second normally open solenoid valve 13 and the movement of the annular baffle 21.

[0054] S5: Rotate the threaded screw 8. The rotation of the threaded screw 8 causes the threaded sleeve 9 to move downward along the threaded screw 8. At this time, the threaded sleeve 9 will push the outer coupling ring 22 downward through the limit guide rod 39. When the outer coupling ring 22 moves downward, it will drive the inner coupling ring 23 and the spur rack 24 to move downward synchronously. This causes the spur rack 24 to drive the spur gear 25 to rotate. At this time, the cam 26 will rotate with the rotation of the spur gear 25. Thus, the cam 26 will squeeze and guide the movable pin 27 through the guide ring groove 29, so that the movable pin 27 drives the insert The rod 28 moves upward, causing the insert rod 28 to retract the annular baffle 21 into the connecting sleeve 15. At this time, a gap appears between the top of the drainage chamber 19 and the bottom of the connecting sleeve 15. The motor 20 is started, which drives the half gear 32 to rotate. When the half gear 32 meshes with the spur gear ring 35, the half gear 32 pushes the spur gear ring 35 to rotate. At this time, the movable ring 34 compresses the arc spring 38 through the arc groove 36, thereby causing the drainage chamber 19 and the spur gear 25 to swing synchronously. When the half gear 32 meshes with the spur gear ring... When the connection sleeve 15 is separated, the movable ring 34 will return to its original position under the elastic restoring force of the arc spring 38. This allows the movable ring 34 to reciprocate through the rotation of the half-gear 32, causing the activated carbon inside the connecting sleeve 15 to fall into the discharge port 31. The activated carbon filter tank 4 is then discharged from the bottom of the discharge port 31. Subsequently, by reversing the rotation of the threaded screw 8, the annular baffle 21 blocks the gap between the connecting sleeve 15 and the drainage chamber 19. Then, the feed pipe 7 is opened, and activated carbon is poured into the feed pipe 7 to allow the activated carbon to circulate within the connecting sleeve 15. The activated carbon is stacked on the side, which allows the inner side of the connecting sleeve 15 to be filled, thereby improving the efficiency of activated carbon replacement. Then, the first normally open solenoid valve 12 and the second normally open solenoid valve 13 are opened. At this time, the aqueous solution entering the activated carbon filter tank 4 will fall into the inner side of the connecting sleeve 15 through the first normally open solenoid valve 12. When the aqueous solution passes through the activated carbon inside the connecting sleeve 15, the aqueous solution is treated by the activated carbon. The treated aqueous solution is discharged through the conical filter plate 17, the drain chamber 19, the drain pipe 11, and the second normally open solenoid valve 13.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
