Description

Technical Field

[0001] This utility model relates to the field of water purification technology, specifically a water purification device for a pharmaceutical workshop. Background Technology

[0002] Purified water is water prepared for pharmaceutical use by distillation, ion exchange, reverse osmosis, or other suitable methods. It contains no additives and is characterized as a colorless, clear liquid; odorless and tasteless. Pharmaceutical purified water systems must comply with Good Manufacturing Practices (GMP) requirements in terms of system design, material selection, preparation process, storage, distribution, and use.

[0003] When processing purified water in a pharmaceutical workshop, the water must first be carefully filtered to avoid impurities in the water affecting the purification results.

[0004] Existing water purification devices in pharmaceutical workshops leave impurities filtered from the water inside the device during use, which can clog the filter screen and affect the filtration rate after prolonged use. Therefore, they do not meet the current requirements. To address this, we propose a new water purification device for pharmaceutical workshops. Utility Model Content

[0005] The purpose of this invention is to provide a water purification device for pharmaceutical workshops, in order to solve the problems mentioned in the background art, such as the impurities filtered from the water remaining inside the device during use, causing filter blockage and affecting the filtration rate after long-term use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water purification device for a pharmaceutical workshop, comprising a tank body, a tank cover movably mounted on the top of the tank body, a filter inner tank fixedly mounted on the bottom of the tank cover, activated carbon disposed inside the filter inner tank, a servo motor fixedly mounted on the top of the tank cover, a rotating shaft connected to the output end of the servo motor via a coupling, the rotating shaft extending through the tank cover and the filter inner tank into the interior of the tank body, a fixing plate fixedly mounted on the bottom of the rotating shaft, cleaning blocks movably mounted on both ends of the fixing plate, a U-shaped filter disc movably mounted inside the tank body, and multiple flexible brushes disposed on the bottom of the fixing plate and the cleaning blocks, the flexible brushes being in contact with the surface of the U-shaped filter disc.

[0009] Preferably, both ends of the fixing plate are provided with spring grooves, and a compression spring is movably installed between the cleaning block and the inside of the spring groove. One end of the compression spring is connected to the inner wall of the spring groove, and the other end of the compression spring is connected to the cleaning block. The surface of the cleaning block near the blocking block is provided with an inclined surface.

[0010] Preferably, a water inlet is provided on one side of the top of the can lid, and a water outlet is provided at the center of the bottom of the can body.

[0011] Preferably, a support frame is fixedly installed on the outer surface of the tank near the bottom.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 4 An embodiment of this utility model provides a water purification device for a pharmaceutical workshop, comprising a tank body 1, a tank cover 2 movably mounted on the top of the tank body 1, a filter inner tank 8 fixedly mounted on the bottom of the tank cover 2, activated carbon 9 disposed inside the filter inner tank 8, a servo motor 4 fixedly mounted on the top of the tank cover 2, the output end of the servo motor 4 being connected to a rotating shaft 5 via a coupling, the rotating shaft 5 extending through the tank cover 2 and the filter inner tank 8 into the interior of the tank body 1, a fixing plate 10 fixedly mounted on the bottom of the rotating shaft 5, cleaning blocks 19 movably mounted on both ends of the fixing plate 10, a Z-shaped filter disc 11 movably mounted inside the tank body 1, and multiple flexible brushes 20 disposed at the bottom of both the fixing plate 10 and the cleaning blocks 19, the flexible brushes 20 being in contact with the surface of the Z-shaped filter disc 11.

[0023] By combining activated carbon 9 and the Z-shaped filter plate 11, the device allows water to enter the inner filter tank 8 through the inlet 3 and undergo a first filtration by activated carbon 9. Then, the water enters the tank body 1 through the bottom of the inner filter tank 8 and undergoes a second filtration by the Z-shaped filter plate 11, thus preventing residual impurities in the water from affecting subsequent purification processes.

[0024] With the cooperation of the fixed plate 10 and the flexible brush 20, the device can be driven by the servo motor 4 to rotate the rotating shaft 5 during use. The rotating shaft 5 drives the fixed plate 10 to rotate, and the flexible brush 20 at the bottom of the fixed plate 10 rotates on the surface of the Z-shaped filter disc 11. This allows the flexible brush 20 to sweep the filtered impurities remaining on the surface of the Z-shaped filter disc 11 to the outermost position, thus avoiding the retention of impurities and affecting the filtration efficiency of water through the Z-shaped filter disc 11.

[0025] A support ring 12 is fixedly installed on the inner wall surface of the tank body 1. The bottom end of the Z-shaped filter disc 11 is in contact with the surface of the support ring 12. A sliding groove is provided on one side of the tank body 1, and an impurity storage plate 13 is slidably installed inside the sliding groove.

[0026] A handle 14 is fixedly installed on the outer side of the impurity storage plate 13, and an impurity storage trough 15 is provided on the inner surface of the impurity storage plate 13. A blocking block 21 is fixedly installed on the inner side of the tank body 1 near the impurity storage plate 13. The surface of the blocking block 21 is in contact with the surface of the impurity storage plate 13, and an inclined surface 16 is provided on the side of the impurity storage plate 13 away from the blocking block 21.

[0027] With the cooperation of the cleaning block 19 and the blocking block 21, when the device is in use, the cleaning block 19 can rotate at the outermost position of the Z-shaped filter disc 11, thereby cleaning the impurities accumulated at the outermost position of the Z-shaped filter disc 11 to the position of the impurity storage plate 13 by the cleaning block 19 and the flexible brush 20. At this time, the impurities will pass through the inclined surface 16 on the surface of the impurity storage plate 13 and enter the impurity storage groove 15 on the surface of the impurity storage plate 13. Then the cleaning block 19 continues to rotate through the rotating shaft 5.

[0028] Both ends of the fixed plate 10 are provided with spring grooves 17. A compression spring 18 is movably installed between the cleaning block 19 and the inside of the spring groove 17. One end of the compression spring 18 is connected to the inner wall of the spring groove 17, and the other end of the compression spring 18 is connected to the cleaning block 19. The surface of the cleaning block 19 near the blocking block 21 is provided with a slope 16.

[0029] A water inlet 3 is provided on one side of the top of the can lid 2, and a water outlet 7 is provided at the center of the bottom of the can body 1.

[0030] A support frame 6 is fixedly installed on the outer surface of the tank body 1 near the bottom.

[0031] When the water purification device in the pharmaceutical workshop is in use, water can enter the inner filter tank 8 through the inlet 3 and undergo a first filtration through activated carbon 9. Then, it enters the tank body 1 through the bottom of the inner filter tank 8 and undergoes a second filtration through the Z-shaped filter disc 11, thus avoiding the impact of residual impurities in the water on subsequent purification processes.

[0032] The rotating shaft 5 can be driven by the servo motor 4 to rotate, thereby driving the fixed plate 10 to rotate. The flexible brush 20 at the bottom of the fixed plate 10 rotates on the surface of the Z-shaped filter disc 11, thereby sweeping the filtered impurities remaining on the surface of the Z-shaped filter disc 11 to the outermost position by the flexible brush 20, thus avoiding the impurities remaining and affecting the efficiency of water filtration through the Z-shaped filter disc 11.

[0033] The cleaning block 19 rotates at the outermost position of the Z-shaped filter disc 11, thereby cleaning the impurities accumulated at the outermost position of the Z-shaped filter disc 11 to the position of the impurity storage plate 13 by the cleaning block 19 and the flexible brush 20. At this time, the impurities will pass through the inclined surface 16 on the surface of the impurity storage plate 13 and enter the impurity storage groove 15 on the surface of the impurity storage plate 13. Then the cleaning block 19 continues to rotate through the rotating shaft 5.

[0034] When the inclined surface 16 of the cleaning block 19 impacts the surface of the blocking block 21, the cleaning block 19 will retract into the spring groove 17, thereby moving the cleaning block 19 above the blocking block 21 and turning past the position of the blocking block 21. Then the cleaning block 19 will be pushed out by the elastic force of the compression spring 18, thereby continuing to clean the outermost position of the Z-shaped filter disc 11 to avoid impurities remaining.

[0035] When impurities accumulate inside the impurity storage tank 15, the impurities inside the impurity storage tank 15 can be emptied and cleaned by grasping the handle 14 and removing the impurity storage plate 13 from the tank 1, thereby avoiding affecting the filtration efficiency of the device.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
