Description

Technical Field

[0001] This application belongs to the field of reverse osmosis device technology, specifically a pharmaceutical reverse osmosis purified water device. Background Technology

[0002] Pharmaceutical reverse osmosis purified water equipment is a key piece of equipment used in the pharmaceutical industry to prepare purified water that meets pharmacopoeia standards. It uses reverse osmosis membrane technology as its core and combines pretreatment, precision filtration and post-treatment processes. The equipment removes suspended solids through a multi-media filter, adsorbs residual chlorine and organic matter through an activated carbon filter, and intercepts fine particles through a security filter. The water is then driven by a high-pressure pump to pass through the reverse osmosis membrane to remove impurities such as bacteria, pyrogens, heavy metals and organic matter. The produced water can be further desalinated by EDI or ion exchange.

[0003] For example, the utility model patent with announcement number CN214809876U discloses a pharmaceutical reverse osmosis purified water device, including several sets of reverse osmosis filters and a mounting frame for fixing the reverse osmosis filters. The mounting frame is provided with a fixing mechanism and an auxiliary support mechanism. The fixing mechanism is set on both sides of the mounting frame for supporting and fixing the two ends of the reverse osmosis filters. It includes end brackets set at both ends of the mounting frame, and an end arc-shaped support rod for placing the reverse osmosis filter is provided between two sets of end brackets located at the same end. This utility model is designed according to existing needs. The fixing mechanism and the auxiliary support mechanism work together to facilitate the support and fixing of the reverse osmosis filter. The fixing arc plate can be controlled to move away from the end brackets by the lifting component, so as to release the fixing of the reverse osmosis filter, which is convenient for the reverse osmosis filter to be taken out as a whole for cleaning. It also facilitates the subsequent disassembly of the reverse osmosis filter and is convenient for use.

[0004] However, in actual use, it was found that although the device achieves the limiting and fixing of the reverse osmosis filter through a fixing mechanism composed of components such as lead screws, bevel gears, and lifting blocks, the fixing mechanism has many parts and requires strict assembly precision, which increases the production and manufacturing costs and makes installation more difficult. At the same time, its fixing method makes all reverse osmosis filters interconnected, making it impossible to disassemble individual filters for maintenance and repair. When one filter malfunctions, the entire fixing mechanism must be operated and adjusted before disassembly, which not only consumes a lot of time and effort, but also seriously affects the maintenance efficiency and flexibility of the equipment. Therefore, a pharmaceutical reverse osmosis purified water equipment is provided. Utility Model Content

[0005] The purpose of this application is to provide a pharmaceutical reverse osmosis purified water device in order to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: A pharmaceutical reverse osmosis purified water device includes a device support, a filter support fixedly installed on the top surface of the device support, a liquid conveying mechanism provided on the top surface of the device support, two fixed supports (first type) fixedly installed near the top of the filter support, and two fixed supports (second type) fixedly installed below the fixed supports (first type) on the front side of the filter support. U-shaped grooves are formed on the sides of the fixed supports (first type) and fixed supports (second type) that are close to each other. A reverse osmosis filter is provided between the fixed supports (first type) and fixed supports (second type), and a limit position is provided between the fixed supports (first type) and fixed supports (second type). The limiting plate has an arc-shaped groove on the side near the reverse osmosis filter. Four fixed support plates are fixedly installed on the side of the limiting plate away from the arc-shaped groove. The four fixed support plates are divided into two groups of two. A movable limiting rod is movably inserted through the top surface of each group of fixed support plates. A circular mounting plate is fixedly installed on the outer surface of the movable limiting rod above the fixed support plate. A spring is fixedly installed at the top of the circular mounting plate. A connecting rod is fixedly installed at one end of the movable limiting rod. Multiple connecting grooves are opened on the inner bottom surface of the U-shaped groove. The bottom end of the connecting rod is inserted into the interior of one of the multiple connecting grooves.

[0007] In a preferred embodiment, a limiting slider is fixedly installed on the top and bottom surfaces of the limiting plate, and the limiting slider is inserted into the interior of the U-shaped groove.

[0008] In a preferred embodiment, rubber limiting seats are fixedly installed on the sides of the fixed bracket one and the fixed bracket two that are close to each other.

[0009] In a preferred embodiment, one end of the reverse osmosis filter is threadedly connected to an inlet pipe, and the outer surface of the end of the reverse osmosis filter away from the inlet pipe is threadedly connected to an outlet pipe.

[0010] In a preferred embodiment, a control box is fixedly installed on the side of the filter bracket away from the fixed bracket.

[0011] In a preferred embodiment, a flexible protective pad is fixedly installed on the inner wall surface of the arc-shaped groove.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: 1. In this application, due to the adoption of the above-mentioned solution, when the device needs to maintain or replace the filter, pressing the rectangular plate at the end of the two movable limiting rods causes the movable limiting rods to move and disengage the connecting rod from the connecting groove. This facilitates the removal of the reverse osmosis filter by sliding the limiting plate, which is convenient for subsequent operations and improves the installation and removal efficiency of the reverse osmosis filter. The overall elastic limiting and sliding structure work together to achieve quick installation and removal of a single reverse osmosis filter, effectively improving the efficiency of filter installation and maintenance.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] refer to Figures 1-4 As shown, a pharmaceutical reverse osmosis purified water device includes a device support 1, a filter support 2 fixedly mounted on the top surface of the device support 1, a liquid conveying mechanism 3 provided on the top surface of the device support 1, two fixed supports 4 fixedly mounted on the front side of the filter support 2 near the top, and a control box 20 fixedly mounted on the side of the filter support 2 away from the fixed supports 4. The device support 1 provides a stable foundation support for the entire purified water device, ensuring the stability of the device during operation. The filter support 2 facilitates the centralized installation of pharmaceutical reverse osmosis purified water components. The liquid conveying mechanism 3 enables stable delivery of the water to be purified. The fixed supports 4 provide structural support for the subsequent installation and fixation of the reverse osmosis filtration pipeline. The control box 20 integrates the control elements of the device, allowing operators to monitor and adjust the operating parameters of the device in real time, achieving automated operation and management, and improving the ease of use and operational safety of the device.

[0017] refer to Figures 1-4As shown, two fixed brackets 5 are fixedly installed on the front side of the filter bracket 2 below the fixed bracket 4. U-shaped grooves 6 are provided on the sides of both fixed brackets 4 and 5 that are close to each other. Rubber limit seats 17 are fixedly installed on the sides of both fixed brackets 4 and 5 that are close to each other. A reverse osmosis filter 7 is arranged between the fixed brackets 4 and 5. One end of the reverse osmosis filter 7 is threadedly connected to an inlet pipe 18, and the outer surface of the end of the reverse osmosis filter 7 away from the inlet pipe 18 is threadedly connected to an outlet pipe 19. The liquid conveying mechanism 3 is connected to the reverse osmosis filter 7. The fixed bracket 2 5 cooperates with the fixed bracket 1 4 to facilitate positioning of the reverse osmosis filter 7 from both the top and bottom. The U-shaped groove 6 provides guidance for the installation and sliding of the limiting plate 8, ensuring the stability of the limiting structure. The rubber limiting seat 17 effectively buffers the vibration during equipment operation, preventing the reverse osmosis filter 7 from shifting due to vibration. At the same time, its flexible material can prevent wear on the filter surface. The threaded inlet pipe 18 and outlet pipe 19 are easy to disassemble and install, facilitating pipe maintenance, cleaning, and filter replacement. The tight connection ensures water circuit sealing and prevents leakage.

[0018] refer to Figures 1-4 As shown, a limiting plate 8 is provided between the fixed bracket 1 4 and the fixed bracket 2 5. Limiting sliders 16 are fixedly installed on the top and bottom surfaces of the limiting plate 8, respectively. The limiting sliders 16 are inserted into the U-shaped groove 6. An arc-shaped groove 9 is provided on the side of the limiting plate 8 near the reverse osmosis filter 7. A flexible protective pad 21 is fixedly installed on the inner wall of the arc-shaped groove 9. The limiting plate 8 allows the limiting slider 16 to slide in the U-shaped groove 6, which can flexibly adjust the limiting position of the reverse osmosis filter 7 to adapt to different specifications of filters. The arc-shaped groove 9 fits the shape of the reverse osmosis filter 7, enhancing the limiting effect and making the filter more stable. The flexible protective pad 21 further protects the outer surface of the filter, reduces contact pressure, and increases friction to prevent the filter from shaking during operation, ensuring stable filtration effect.

[0019] refer to Figures 1-4As shown, four fixed support plates 10 are fixedly installed on the side of the limiting plate 8 away from the arc-shaped groove 9. The four fixed support plates 10 are divided into two groups of two, and a movable limiting rod 11 is movably inserted through the top surface of each group of fixed support plates 10. A circular mounting plate 12 is fixedly installed on the outer surface of the movable limiting rod 11 above the fixed support plate 10. A spring 13 is fixedly installed on the top of the circular mounting plate 12. A connecting rod 14 is fixedly installed on one end of the movable limiting rod 11. Multiple connecting grooves 15 are opened on the bottom surface of the U-shaped groove 6. The bottom end of the connecting rod 14 is inserted into multiple connecting grooves 15. Inside one of the connecting slots 15, an elastic limiting structure is formed by a fixed support plate 10, a movable limiting rod 11, a circular mounting plate 12, and a spring 13. The elastic force provided by the spring 13 allows the movable limiting rod 11 to drive the connecting rod 14 to be tightly inserted into the connecting slot 15, thereby achieving rapid positioning and locking of the limiting plate 8. The positions of the limiting plates 8 can be adjusted according to actual needs in multiple connecting slots 15, improving the compatibility of the equipment with reverse osmosis filters 7 of different sizes. The overall design facilitates quick disassembly and assembly of the limiting plates 8, thus making it convenient to perform maintenance operations such as inspection and replacement of the reverse osmosis filter 7.

[0020] The implementation principle of this embodiment of a pharmaceutical reverse osmosis purified water device is as follows: The water to be purified is sent to the reverse osmosis filter 7 through the liquid conveying mechanism 3 and the inlet pipe 18. After impurity filtration, the purified water flows out from the outlet pipe 19. During installation, the reverse osmosis filter 7 is placed in the rubber limiting seat 17 between the fixed bracket 1 4 and the fixed bracket 2 5, and the rectangular plate at the end of the movable limiting rod 11 is pressed, so that the two movable limiting rods 11 move towards each other. At this time, the connecting rod 14 will disengage from the bottom connecting groove 15 of the U-shaped groove 6. At this time, the personnel can slide the limiting plate 8 to allow the limiting slider 16 to move in the U-shaped groove 6, thereby making the arc groove 9 on one side of the limiting plate 8 fit with the filter. At this time, when the personnel release the movable limiting plate 8, the filter will be able to move. When the movable limit rod 11 is moved, the spring 13 provides pressure to insert the connecting rod 14 into the connecting groove 15, which securely fixes the limit plate 8, thereby limiting and fixing the reverse osmosis filter 7. The device is easy to operate. When maintenance or replacement of the filter is required, press the rectangular plates at the ends of the two movable limit rods 11, which pulls the movable limit rods 11 to move the connecting rod 14 away from the connecting groove 15. This makes it easy to slide the limit plate 8 to disassemble the reverse osmosis filter 7 for subsequent operations. It can effectively and quickly disassemble and install a single reverse osmosis filter 7, improving the efficiency of reverse osmosis filter installation and disassembly. The overall elastic limit and sliding structure work together to achieve quick disassembly and assembly of a single reverse osmosis filter 7, effectively improving the efficiency of filter installation and maintenance.
