Description

Technical Field

[0001] The present invention relates to the technical field of purified water preparation, and in particular to a purified water preparation device with intelligent pressure regulation. Background Art

[0002] Purified water is water that has been treated using specific technologies to remove impurities, ions, organic matter, and microorganisms, achieving certain water quality standards. Purified water is widely used in the pharmaceutical, medical, chemical, and electronics industries, serving as a crucial raw material for the production of pharmaceuticals, medical devices, cosmetics, food additives, and other products.

[0003] In purified water preparation equipment, a pressure gauge is often used in conjunction with a solenoid valve to control the pressure regulation during raw water purification.

[0004] After the raw water is purified, it needs to be sterilized by a sterilization component and then sent to the production line for use. The existing sterilization component is often equipped with a transparent glass tube in the center of a closed tube. Ultraviolet sterilization lamps for sterilization are arranged inside the closed tube and around the transparent glass tube, so that the purified water can be sterilized by ultraviolet radiation when passing through the transparent glass tube. The purified water has a short passage time in the traditional glass straight tube and a short exposure time to ultraviolet radiation, which limits its sterilization effect. Secondly, since the ultraviolet sterilization lamp is enclosed in a closed tube, it needs regular maintenance during long-term use, and the enclosed shell needs to be disassembled for maintenance and inspection, which is cumbersome. The enclosed shell cannot be removed directly. Direct removal will cause the entire space to be filled with ultraviolet radiation when the ultraviolet lamp is working. Operators need to wear protective clothing to enter, and the preparation operation is more complicated.

[0005] Therefore, we propose a pressure intelligent regulation purified water preparation device to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0036] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figures 1-13As shown, a pressure intelligent regulation purified water preparation device includes a raw water tank 1, the raw water tank 1 is connected to a raw water pump 2 through a pipeline, the raw water pump 2 is connected to a filter component 3 through a pipeline, the filter component 3 includes a quartz sand filter, which is used to filter the sediment, suspended matter and colloid in the raw water, and secondly includes an activated carbon filter, which is used to adsorb residual chlorine and organic matter in the water, and finally a precision filter, which is used to remove tiny particles in the water, the filter component 3 is connected to a first-level high-pressure pump 4 through a pipeline, the first-level high-pressure pump 4 is connected to an infiltration component 5 through a pipeline, and an electromagnetic valve and a pressure gauge for opening and closing are provided on the pipeline entering the infiltration component 5. The meter detects the water flow pressure in the pipeline, and sets the pressure value on the controller. The controller's electrical signal acts on the pipeline solenoid valve in front of the osmosis component 5 to adjust the degree of valve opening to control the water inlet pressure, so as to achieve water pressure control before osmosis. The osmosis component 5 includes a primary or secondary reverse osmosis membrane, which can remove soluble salts, bacteria and viruses in the raw water. The osmosis component 5 is connected to a secondary high-pressure pump 6 through a pipeline, and the secondary high-pressure pump 6 is connected to a water storage tank 7 through a pipeline. The water storage tank 7 is connected to a tertiary high-pressure pump 8 through a pipeline. The tertiary high-pressure pump 8 is connected to a sterilization component through a pipeline. The sterilization component often uses an ultraviolet lamp to sterilize the prepared pure water.

[0038] Furthermore, the sterilization component includes a transparent tube 9, which is provided with at least two even-numbered bends 91. The bends 91 can prolong the flow time of pure water in the shell 10, thereby prolonging the irradiation time of the pure water by the ultraviolet lamp 11 and improving the sterilization rate. The even-numbered bends 91 can ensure that the water inlet and the water outlet are located in relative positions. A fully enclosed shell 10 is provided on the outside of the transparent tube 9. In order to facilitate the installation of the shell 10, the shell 10 adopts two upper and lower half shells. When assembling the device, the lower shell is first welded to the side panels 14 on both sides, and then the internal structure of the shell 10 is installed, and then the upper shell is placed, and the upper shell and the lower shell are welded together. The upper shell body 10 is connected to form a complete shell body 10, and then the side panels 14 on both sides are welded to further improve its sealing and connection stability. The completely sealed shell body 10 prevents subsequent maintenance operations on the ultraviolet lamp 11. Therefore, an observation panel 12 that is easy to disassemble is provided on the upper shell body. Subsequent maintenance and inspection operations on the ultraviolet lamp 11 are all performed from the position of the detachable observation panel 12. The transparent tube 9 with the bend 91 can increase the time that the purified water is irradiated by ultraviolet rays when passing through, thereby effectively improving the sterilization rate. Secondly, by providing the bend 91, the overall length of the transparent tube 9 is reduced, and it can be configured according to the actual length of the ultraviolet lamp 11, which is more practical.

[0039] Furthermore, at least two ultraviolet lamps 11 are provided in the housing 10 and around the transparent tube 9. An observation panel 12 is detachably connected to the housing 10. The observation panel 12 can be removed when necessary to facilitate removal or replacement of a faulty ultraviolet lamp 11 from the inside. The observation panel 12 can be connected to the housing 10 in any manner that is easily detachable. In the figure, a hand groove for easy access is provided at both ends of the long side of the observation panel 12. A groove body for padding the observation panel 12 is provided at the top of the housing 10. There is a step for placing the observation plate 12. In order to increase the tightness of the observation plate 12 placed in the groove body, grooves are opened at the bottom of both sides in the width direction of the groove body. Rubber pads are fixed in the grooves. When the observation plate 12 is placed, the friction between the rubber pads and the groove body can increase the tightness of the connection between the observation plate 12 and the groove body. At the same time, the observation plate 12 can also cooperate with the steps to seal the groove body to avoid light leakage during the operation of the ultraviolet lamp 11. The hidden hand groove can also provide a convenient way to remove the observation plate 12 while avoiding accidental touching.

[0040] In this embodiment, the sterilization component also includes a frame 13 supporting the transparent tube 9. The frame 13 includes two symmetrically arranged side panels 14. The side panels 14 are respectively provided with perforations for the passage of pipes. Connectors are provided in the perforations. The adjacent ends of the two connectors are respectively fixedly connected to one end of the transparent tube 9. The connectors pass through the perforations, and the two ends are respectively connected to the transparent tube 9 and the external pipe, so as to facilitate the flow of pure water in and out of the sterilization component.

[0041] In this embodiment, the sterilization assembly further includes a lamp side frame 15 for supporting a plurality of ultraviolet lamp tubes 11. The lamp side frame 15 is fixedly connected to the inner side of the adjacent side plate 14. A connecting component 16 that can rotate around the center of the lamp side frame 15 is provided on the lamp side frame 15. The connecting component 16 is used to provide support for the ultraviolet lamp tubes 11 on both sides. At the same time, the ultraviolet lamp tubes 11 can be driven by the support to rotate synchronously with the connecting component 16 when needed, so as to cooperate with the fixed position observation plate 12 and facilitate the replacement of different ultraviolet lamp tubes 11 from the observation plate 12. The connecting component 16 is provided with no less than two connecting ends 17, which are used to provide support for the ultraviolet lamp tube 11. The connecting end 17 is detachably connected to one end of the adjacent ultraviolet lamp tube 11. The connecting end 17 and the ultraviolet lamp tube 11 can adopt any detachable connection method, such as a snap connection, a locking piece connection, etc. By cooperating with the detachable observation plate 12 and the rotatable connecting component 16, the ultraviolet germicidal lamps at different positions inside can be easily removed, replaced and installed, reducing the tediousness during maintenance.

[0042] In this embodiment, a control groove 18 is provided on one side of the observation plate 12 near one of the connecting parts 16, and an inspection part 19 that can drive the connecting part 16 to rotate is provided in the control groove 18. The inspection part 19 is used to facilitate maintenance personnel to power on the ultraviolet lamp 11 without opening the outer shell 10 and the observation plate 12, and drive the connecting part 16 to rotate to drive multiple ultraviolet lamps 11 to pass through the position of the observation plate 12 in turn, and inspect different ultraviolet lamps 11 through the observation port 20 provided on the observation plate 12 to determine whether they are working normally.

[0043] In this embodiment, an observation port 20 is further provided on the observation plate 12, and a filter glass 21 is fixedly installed in the observation port 20. The filter glass 21 is also called anti-ultraviolet glass, which can block minor injuries to the human body caused by directly looking at ultraviolet rays, and at the same time can observe whether the ultraviolet lamp 11 is in normal working condition. On the outer shell 10, only one observation port 20 is provided at this position to facilitate observation by maintenance personnel, and at the same time, it is cooperated with the rotatable connecting part 16 to facilitate observation of different ultraviolet lamps 11 from one fixed observation port 20.

[0044] In this embodiment, the connecting component 16 includes a rotation groove 22 formed on the lamp side frame 15. The rotation groove 22 is used to facilitate the sliding of the rotating ring 23 therein and does not protrude from the outside of the lamp side frame 15. The rotating groove 22 is movably connected to the rotating ring 23 with a center through hole. A pressure cover plate 25 is also provided on the lamp side frame 15 on one side of the rotation groove 22. The pressure cover plate 25 is also designed to be a center through hole type, and its center through hole is larger than the center through hole of the rotating ring 23, so as to expose the rotating ring 23. At least two extension rods 24 are fixed around the rotating ring 23. The extension rods 24 are used to connect the rotating ring 23 and the connecting end 17. The extension rods 24 can be welded to each other. The end of the rod 24 is fixedly connected to the adjacent connecting end 17, and the outer sides of multiple extension rods 24 are fixedly connected to the same connecting ring 26. The connecting ring 26 is designed with two functions. One is to support the separately extended extension rod 24 to prevent it from bending due to gravity for a long time and improve its support stability. The second is to facilitate subsequent cooperation with the inspection component 19. By cooperating with the continuous connecting ring 26, the rotating ring 23 and the ultraviolet lamp tube 11 can be continuously driven to rotate. A bending section 241 for avoiding the transparent tube 9 is provided on the extension rod 24. The bending section 241 is used to avoid interference between the connecting end 17 and the transparent tube 9 when it rotates with the rotating ring 23 and the connecting ring 26.

[0045] In this embodiment, a boss 27 is formed at the bottom of the observation plate 12 and below the control groove 18. The boss 27 is used to increase the lifting stroke of the slider 31. The control groove 18 passes through the boss 27. A stepped groove 28 is also provided on the long side of the control groove 18. The bottom end opening area of the stepped groove 28 is narrowed, and it is used to place the spring 30 on the inside and limit the lowest moving position of the slider 31. Vertical grooves 29 are provided on the adjacent sides of the two stepped grooves 28. The vertical grooves 29 are used to allow the center axis 32 to pass through and limit the side of the slider 31 to prevent it from escaping from the side of the stepped groove 28.

[0046] In this embodiment, the inspection component 19 includes a spring 30 arranged at the bottom of the stepped groove 28. The spring 30 is used to provide an upward thrust to the slider 31 at all times when there is no manual intervention, ensuring that the slider 31 is in a higher position when there is no manual intervention. The stepped grooves 28 on both sides are respectively slidably connected with the sliders 31. A central shaft 32 is detachably connected between the two sliders 31. The outer side of the slider 31 is rotatably connected to the extrusion wheel 33. The extrusion wheel 33 is provided with an extrusion groove 34 for the friction connection ring 26, and a rubber pad with a high friction coefficient is provided in the extrusion groove 34. When inspection is required, the maintenance personnel presses the extrusion wheel 33 downward so that it drives the slider 31 to press the spring 30 downward through the central axis 32 until the rubber pad on the extrusion groove 34 is in full contact with the connecting ring 26. At this time, the maintenance personnel need to further rotate the extrusion wheel 33 while keeping the extrusion wheel 33 pressed down so that the friction between the rubber pad in the extrusion groove 34 and the connecting ring 26 drives the connecting ring 26 to rotate, and then the multiple ultraviolet lamps 11 can be driven to move synchronously through the connecting component 16, which is convenient for the maintenance personnel to inspect the multiple ultraviolet lamps 11 without opening the housing 10. Visual inspection shows that light blocking members 35 are provided on both sides of the outer side of the extrusion wheel 33. Since the extrusion wheel 33 is a rotating body and an extrusion groove 34 is provided on it, it cannot completely block the light from the control groove 18. This will cause residual light to leak out from both sides of the control groove 18 when the ultraviolet lamp 11 is working. Therefore, two light blocking members 35 are provided on the opposite sides of the axis of the extrusion wheel 33. A fitting portion is provided on the side of the light blocking member 35 close to the extrusion wheel 33, and its outer contour fills the gap between the extrusion wheel 33 and the control groove 18. When installing, the two light blocking members 35 are aligned with the extrusion wheel 33 to prevent the light from leaking out. The pressing wheels 33 are squeezed together and synchronously inserted into the control groove 18 along with the slider 31. Due to the shape of the fitting portion on the light blocking member 35, the squeezing wheel 33 will come into contact with the light blocking member 35 and transmit force regardless of whether it is raised or lowered, so that the two light blocking members 35 and the squeezing wheel 33 move synchronously. The light blocking member 35 is slidably connected to the short side of the control groove 18, and a light blocking plate 351 is formed in the middle of the light blocking member 35. The light blocking member 35 is a hollow structure, so a light blocking plate 351 is formed at its center to prevent the light source below from passing through the light blocking member 35. The light blocking member 35 is manufactured using a mold.

[0047] In this embodiment, a recessed portion 261 is formed on the outside of the connecting ring 26, and several recessed portions 261 are arranged around the outer side of the connecting ring 26. The recessed portions 261 can increase the friction between the contact with the rubber pad on the extrusion groove 34, and secondly, can also cooperate with the stopping structure to stop the connecting ring 26 to prevent it from accidentally rotating.

[0048] In this embodiment, a stop structure is provided in one of the light blocking members 35, and the stop structure includes a guide platform 36 formed on the top of the light blocking plate 351 on the light blocking member 35, and the guide platform 36 is used to increase the guiding distance of the light blocking member 35 to the stop column 37, thereby improving the guiding stability thereof. A stop column 37 is movably connected in the guide platform 36, and the bottom of the stop column 37 is set as an arc surface. The stop column 37 is supported by a material with a higher density. At the same time, there is a clearance fit between the stop column 37 and the opening in the guide platform 36, so that the stop column 37 can fall naturally under normal circumstances and be stuck in the recessed portion 261 on the connecting ring 26. The end near the top of the stop column 37 is also opened. A circular hole is provided to increase friction and provide a fulcrum when in contact with the hand. When the connecting ring 26 needs to be stopped, the pressure on the extrusion wheel 33 is first released, so that the slider 31 drives the extrusion wheel 33 upward under the elastic force of the spring 30, so that the extrusion wheel 33 is no longer in contact with the connecting ring 26. At this time, the extrusion wheel 33 is rotated and is in an idling state, and will not drive the connecting ring 26 to rotate. Secondly, when the extrusion wheel 33 moves upward, it will drive the light blocking member 35 to move upward, and one of the stop posts 37 in the guide platform 36 will drop under the action of gravity and get stuck in an adjacent recess 261 on the connecting ring 26. At this time, it is difficult for the connecting ring 26 to push the stop post 37 through the recess 261. The upper end of the stop post 37 is completely in the guide platform 36 and is difficult to remove. When the connecting ring 26 needs to be rotated, the extrusion wheel 33 is pressed downward, so that it drives the sliders 31 on both sides to descend in the stepped groove 28 through the central axis 32. At the same time, the compression spring 30 is deformed and stores elastic force until the reaction force provided by the extrusion wheel 33 contacts the connecting ring 26. At this time, the extrusion wheel 33 descends and the light blocking members 35 on both sides are also lowered, so that the stop post 37 is exposed from the guide platform 36. At this time, it is necessary to pinch the upper end of the stop post 37 and pull it upward so that its bottom end is no longer limited to one of the recessed portions 261. While maintaining downward pressure on the extrusion wheel 33, the extrusion wheel 33 is rotated, and the situation inside the housing 10 is observed through the filter glass 21 at the observation port 20. At the same time, one ultraviolet lamp 11 after another continuously passes under the filter glass 21 to determine whether each ultraviolet lamp 11 is working normally. The inspection component 19 and the filter glass 21 are arranged to cooperate, so that maintenance personnel can observe the brightness and brightness of different external ultraviolet germicidal lamps in the housing 10 without disassembling the housing 10 to determine whether they need to be repaired or replaced, which simplifies the inspection operation of maintenance personnel, eliminates the need to wear additional safety gear, and eliminates the need to disassemble any structure.
