Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and more specifically, to a scale inhibitor component for a medical pure water reverse osmosis membrane. Background Technology

[0002] Medical purified water refers to water that has undergone special treatment to achieve extremely high purity. Medical purified water is often produced by treating raw water (such as drinking water) using technologies such as distillation, ion exchange, and reverse osmosis to remove various impurities and ions, ensuring its purity meets the requirements for medical equipment cleaning, pharmaceutical production, and experimental water. Before using a reverse osmosis membrane, a scale inhibitor is often installed to reduce impurities accumulating on the outer wall of the membrane. A scale inhibitor is then added to the drinking water located within the scale inhibitor, allowing the drinking water to pass through the scale inhibitor before being treated by the reverse osmosis membrane.

[0003] Existing scale inhibitor components typically rely solely on the flow of raw water to mix the scale inhibitor with the raw water when adding scale inhibitors, making it difficult to ensure uniform mixing. Therefore, improvements are needed. Utility Model Content

[0033] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0034] The following is in conjunction with the appendix Figures 1-8 This embodiment will be described in further detail.

[0035] Please see Figures 1-3This embodiment of a medical pure water reverse osmosis membrane scale inhibitor component includes a housing 100, a cavity inside the housing 100, a detachable filter plate 120 inside the cavity, a fixing member on the housing 100 for fixing the filter plate 120, the filter plate 120 dividing the cavity into a front cavity and a rear cavity, a detachable cylinder 130 on the housing 100 located in the front cavity, a mixing chamber with an open top inside the cylinder 130, a water inlet pipe 131 fixedly connected to one side of the cylinder 130, a rotatable and liftable mixing component inside the mixing chamber, a driving member on the housing 100 for driving the mixing component to rotate and lift, and a detachable side plate 102 on the opposite side wall of the housing 100.

[0036] In this embodiment, during the process of treating drinking water to form medical purified water, drinking water is first continuously injected into the cylinder 130 through the inlet pipe 131. A dosing pipe 312 is fixedly connected to the upper end of the cylinder 130. A scale inhibitor solution (such as hydrochloric acid, nitric acid, or oxalic acid) is pumped into the cylinder 130 through the dosing pipe 312 using a metering pump. The scale inhibitor solution and drinking water added to the cylinder 130 are mixed by a mixing component. A baffle plate with multiple perforations is also provided at the bottom of the cylinder 130, thus ensuring that the drinking water in the cylinder 130 is properly circulated. After the water and scale inhibitor solution are mixed, they can flow into the cavity through the leak hole. In this embodiment, the housing 100 located in the rear cavity is provided with a water outlet pipe 500 that connects to the rear cavity. The water outlet pipe 500 is connected to an existing reverse osmosis membrane device (not shown in the figure). A filter screen 700 is fixedly connected to the filter plate 120 located in the cavity. The filter screen 700 can intercept impurities that may exist in the drinking water and pre-filter it. After the drinking water has been pre-filtered, it can enter the reverse osmosis membrane module for treatment through the water outlet pipe 500.

[0037] In this embodiment, the descaling agent solution located in the cylinder 130 can be fully mixed with drinking water through the mixing component. Compared with the existing method, the descaling agent solution in this embodiment is not only mixed with the drinking water through the flow of drinking water, but also, in cooperation with the mixing component, can achieve better mixing between the descaling agent solution and drinking water.

[0038] Specifically, a first flange 200 communicating with the cavity is fixedly connected to the upper end face of the housing 100, and a second flange 210 is fixedly connected to the bottom end of the cylinder 130. The first flange 200 and the second flange 210 are detachably connected by bolts, which facilitates the removal of the cylinder 130 from the housing 100 for cleaning.

[0039] like Figure 4As shown, in this embodiment, the mixing component includes a liftable mixing plate 400. The surface of the mixing plate 400 is provided with multiple arc-shaped grooves 401. The mixed water in the mixing chamber can flow through the arc-shaped grooves 401. Specifically, the mixing plate 400 is always located below the water inlet pipe 131. The mixing plate 400 moves up and down in the mixing chamber to agitate the drinking water and scale inhibitor solution in the mixing chamber.

[0040] like Figures 1-4 As shown, in this embodiment, the upper opening of the mixing chamber is provided with a splicable upper cover, the upper cover is threadedly connected to the cylinder 130, an extension column 410 with one end penetrating through the upper cover is fixedly connected to the mixing plate 400, and a bracket 110 is fixedly connected to the upper end face of the housing 100; the driving component includes an electric push rod 111 fixedly connected to the lower end of the bracket 110, the output shaft of the electric push rod 111 is detachably connected to a bearing seat 412 by screws, and the upper end of the extension column 410 is rotatably installed in the bearing seat 412.

[0041] In this embodiment, when the electric push rod 111 is started, the output end of the electric push rod 111 can drive the extension column 410 and the mixing plate 400 to rise and fall in the mixing chamber, thereby mixing the drinking water and scale inhibitor solvent added to the mixing chamber.

[0042] like Figures 1-4 As shown, in this embodiment, a flipping plate 402 is provided on the mixing plate 400, and a spiral groove 411 is provided on the outer side wall of the extension column 410 near its upper end along its axial direction. A limiting block is provided in the upper cover and slides in the corresponding spiral groove 411. The limiting block slides in the spiral groove 411 to drive the extension column 410 to rotate.

[0043] In this embodiment, the flipping plate 402 is fixedly connected to the outer wall of the extension column 410 along the axial direction of the extension column 410. The upper cover is provided with a through hole for the extension column 410 to pass through. The limiting block is disposed in the through hole. Since the upper cover is fixedly connected to the upper end of the cylinder 130, the position of the limiting block relative to the cylinder 130 is fixed. The extension column 410 is rotatably connected to the output end of the electric push rod 111. When the output end of the electric push rod 111 drives the extension column 410 to rise and fall in the mixing chamber, the limiting block can abut against the side wall of the spiral groove 411, so that the extension column 410 rotates. This causes the mixing plate 400 and the flipping plate 402 to rotate, and finally flips the drinking water and scale inhibitor solution in the mixing chamber, so that the mixing effect of the two is better.

[0044] like Figures 1-8As shown, in this embodiment, the housing 100 is provided with a notch 510 for inserting the filter plate 120. A detachable connecting block 600 is provided on the housing 100 on one side of the notch 510 by screws. The connecting block 600 is provided with a connecting hole 601. The fixing member includes a connecting cylinder 710 fixedly connected to the side of the filter plate 120 away from the connecting block 600. A movable connecting rod 814 is provided inside the connecting cylinder 710. The connecting rod 814 extends into the connecting hole 601 to fix the filter plate 120 on the housing 100.

[0045] In this embodiment, multiple notches 510 are provided along the length of the housing 100 (not shown in the figure), and filter plates 120 are inserted into the corresponding notches 510, so that the drinking water in the cavity can be filtered by the filter screen 700, thereby reducing the impurities that may exist in the drinking water.

[0046] When the filter screen 700 needs to be cleaned or replaced after a period of use, the connecting rod 814 can be moved so that one end is disengaged from the connecting hole 601, thereby releasing the filter plate 120 from its fixation. At this time, the filter plate 120 can be moved away from the housing 100 to remove it from the housing 100 and clean the impurities on the filter screen 700.

[0047] like Figures 6-8 As shown, in this embodiment, the connecting cylinder 710 is provided with a connecting cavity 800 with one end open. A plug 815 is provided at the opening of the connecting cavity 800. The plug 815 is threaded into the connecting cylinder 710. A movable plate 810 is provided in the connecting cavity 800 and is attached to its inner wall. A connecting rod 814 is fixedly connected to the side of the movable plate 810 near the connecting block 600. An extension rod 811 is fixedly connected to the side of the movable plate 810 away from the connecting block 600. One end of the extension rod 811 extends out of the connecting cavity 800 through the plug 815. A spring 812 is sleeved on the extension rod 811 located in the connecting cavity 800. The spring 812 is used to push the connecting rod 814 into the connecting hole 601.

[0048] In this embodiment, one end of the spring 812 abuts against the cap 815, and the other end of the spring 812 abuts against the moving plate 810. Under the pushing force of the spring 812, the moving plate 810 can be pushed to move closer to the connecting block 600, so that the connecting rod 814 extends into the connecting hole 601. When it is necessary to remove the filter plate 120 from the housing 100, the extension rod 811 can be moved away from the connecting block 600, so that the connecting rod 814 can be disengaged from the connecting hole 601.

[0049] Specifically, to facilitate pulling the extension rod 811, a pulling block 813 is connected to the extended end of the extension rod 811 by screws, and the connecting block 600 has an inclined surface 602 on the side near the notch 510. When the filter plate 120 moves down, the connecting rod 814 will contact the side wall of the connecting block 600, causing the connecting rod 814 to gradually retract into the connecting cylinder 710. When the connecting rod 814 is aligned with the connecting hole 601, under the elastic force of the spring 812, one end of the connecting rod 814 will extend into the connecting hole 601. Thus, when installing the filter plate 120, there is no need to manually move the extension rod 811, and the size of the filter plate 120 is compatible with the size of the notch 510. When the filter plate 120 is inserted into the notch 510, the connecting rod 814 can correspond to the position of the connecting block 600.

[0050] In order to reduce the possibility of drinking water leaking out from the notch 510, a sealing strip (not shown in the figure) is provided on the opposite surface of the filter plate 120.

[0051] In order to reduce the shaking of the spring 812 and thus affect the fixing effect of the filter plate 120, in this embodiment, the two ends of the spring 812 are provided with rubber pads that abut against the plug cap 815 or the moving plate 810.

[0052] like Figure 1 As shown, in this embodiment, a cleaning port 101 is provided on the opposite side wall of the housing 100, and a bolt 103 for connecting with the cleaning port 101 is provided on the side plate 102.

[0053] In this embodiment, after a period of use, the side plate 102 can be removed from the housing 100 to expose the cleaning port 101 so that the operator can use cleaning tools to clean the inside of the housing 100.

[0054] In order to ensure the sealing effect, a sealing ring (not shown in the figure) is provided on the side of the side plate 102 near the cleaning port 101 and at the edge.

[0055] like Figure 3 As shown, in this embodiment, the upper cover includes a first half cover 310 and a second half cover 300 that can be spliced ​​together. The side wall of the first half cover 310 is provided with an insertion interface 311, and the side wall of the second half cover 300 is provided with an insertion block 301 that can extend into the corresponding insertion interface 311. The first half cover 310 is provided with countersunk bolts 320 for fixing the insertion block 301.

[0056] In this embodiment, when the first half cover 310 and the second half cover 300 need to be assembled to form the upper cover, the plug block 301 can be aligned with the plug interface 311 and inserted, and then the two can be connected by the countersunk bolt 320.

[0057] Specifically, the edges of the first half-cover 310 and the second half-cover 300 are bent to form a connecting half-ring. The connecting half-ring has a matching internal thread inside. When the two connecting half-rings are combined to form a connecting ring, the internal threads match to form a thread. The connecting ring is connected to the outer wall of the cylinder 130 through the thread.

[0058] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
