Description

Technical Field

[0001] This utility model relates to the technical field of water treatment equipment, and in particular to a modular reverse osmosis water treatment equipment that is easy to maintain. Background Technology

[0002] With the increasing demand for water resource recycling, reverse osmosis water treatment technology, with its high-efficiency purification capabilities, is constantly expanding its application scenarios in industrial production, municipal water supply and other fields. As the treatment scale increases and water quality conditions become more diversified, the requirements for modular flexibility, ease of maintenance and adaptability to operating conditions during equipment operation are becoming increasingly prominent. Modular design enables the rapid combination and independent operation of each functional unit, which simplifies the maintenance process of core components while ensuring stable treatment efficiency.

[0003] Traditional reverse osmosis water treatment equipment suffers from inconvenient maintenance, excessive integration of core components, and the need to disassemble the entire structure for the repair of a single component, resulting in long downtime.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN218465647U that discloses a modular reverse osmosis water treatment device. The patent describes a device that "uses a rectangular frame, support rods, a permeation component, a fixing component, a filter component, and a pressure component. The device is fixed in a suitable position. The rectangular frame is then fixedly installed. The permeation component is connected to the pressure pump on the pressure component via an inlet pipe. The filter component and the fixing component are then installed. This device separates each stage of the reverse osmosis water treatment process and connects them with connectors, facilitating modular disassembly and assembly, saving time and simplifying transportation." However, repairing a single component requires disassembling the entire structure, making it inconvenient to remove and clean or replace the filter screen.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0006] The purpose of this utility model is to provide a modular reverse osmosis water treatment device that is easy to maintain, so as to solve the problem of inconvenient maintenance of traditional reverse osmosis water treatment devices mentioned in the background art, such as the high integration of core components, the need to disassemble the entire structure for the maintenance of a single component, resulting in long downtime.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a modular reverse osmosis water treatment device that is easy to maintain, comprising a base, a rectangular frame at the upper end of the base, a limiting ring fixedly installed at the upper end of the rectangular frame, a reverse osmosis pipe at the upper end of the limiting ring, a water pipe at the front end of the reverse osmosis pipe, a column at the upper end of the base, a protective shell fixedly installed at the upper end of the column, a sealing ring at the front end of the protective shell, a limiting strip at the front end of the protective shell, and a safety device on the inner side of the protective shell. The mounting frame has a first screen fixedly mounted on its upper end, a partition plate at its rear end, a guide rail at its upper end, a slider at its lower end, threaded rods fixedly mounted through both ends of the slider, a connecting rod fixedly mounted at its lower end, a cleaning roller sleeved around the outer ring of the connecting rod, a gear fixedly mounted at the rear end of the cleaning roller, a fixing plate fixedly mounted at the front end of the partition plate, a rack fixedly mounted at the lower end of the fixing plate, and baffles fixedly mounted through both ends of the protective shell.

[0008] Preferably, an inlet pipe is fixedly installed at the upper end of the protective shell, and an outlet pipe is provided at the lower end of the protective shell. The protective shell and the water pipe are connected through the outlet pipe. A groove adapted to the sliding of the baffle is processed on the partition plate. When the baffle slides along the groove, it blocks half of the inlet pipe.

[0009] Preferably, the mounting brackets are provided in two sets and are symmetrically distributed on both sides of the partition.

[0010] Preferably, the outer ring of the threaded rod is fitted with a timing pulley, and the outer ring of another set of timing pulleys is fitted with a first belt.

[0011] Preferably, a pressure pump is provided at the upper end of the base, and the pressure pump is connected to the reverse osmosis pipe through a water pipe.

[0012] Preferably, a drive motor is provided at the upper end of the protective shell, the output end of the drive motor is connected to a second belt through a synchronous pulley, the second belt is connected to the output end of the reducer through another set of synchronous pulleys, and the threaded rod is connected to the other output end of the reducer through a coupling.

[0013] Preferably, a guide plate is provided at the right end of the first screen, a collection pool is provided at the lower end of the guide plate, and a second screen is fixedly installed at the lower end of the mounting frame.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: This modular reverse osmosis water treatment equipment, which is easy to maintain, adopts a layered independent modular architecture. A rectangular frame at the top of the base and a limiting ring form a dedicated fixing structure. The size of the limiting ring and the reverse osmosis tube are precisely matched, which can not only ensure the stability of the reverse osmosis tube during operation, but also allow the reverse osmosis tube to be removed individually by simply disassembling the limiting ring without involving other parts. The mounting bracket is designed in two sets, symmetrically distributed on both sides of the partition. When it needs to be disassembled and replaced, simply slide the limiting strip up and down to unlock it, and then pull the handle at the front end of the mounting bracket to pull it out smoothly. During this process, the sealing ring will fit tightly against the surface of the mounting bracket, simultaneously scraping away residual impurities and moisture, thereby ensuring that the device remains clean before and after maintenance. Combined with the sliding baffle on the partition, when one set of mounting brackets is being maintained, the baffle can slide to the corresponding position to block part of the inlet pipe, so that the water flow only passes through the other set of mounting brackets to complete the filtration operation, thereby realizing non-stop maintenance of the equipment.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a modular reverse osmosis water treatment device that is easy to maintain, including a base 1, a rectangular frame 2 at the upper end of the base 1, a limiting ring 3 fixedly installed at the upper end of the rectangular frame 2, a reverse osmosis pipe 4 at the upper end of the limiting ring 3, a water pipe 5 at the front end of the reverse osmosis pipe 4, a column 6 at the upper end of the base 1, a protective shell 7 fixedly installed at the upper end of the column 6, a sealing ring 8 at the front end of the protective shell 7, a limiting strip 9 at the front end of the protective shell 7, and a mounting bracket 10 inside the protective shell 7, with the upper end of the mounting bracket 10 fixed... The first screen 11 is installed, and the rear end of the mounting frame 10 is provided with a partition 12. The upper end of the first screen 11 is provided with a guide rail 13, and the lower end of the guide rail 13 is provided with a slider 14. Both ends of the slider 14 are fixedly installed with threaded rods 15. The lower end of the slider 14 is fixedly installed with a connecting rod 16. The outer ring of the connecting rod 16 is fitted with a cleaning roller 17. The rear end of the cleaning roller 17 is fixedly installed with a gear 18. The front end of the partition 12 is fixedly installed with a fixing plate 19. The lower end of the fixing plate 19 is fixedly installed with a rack 20. Both ends of the protective shell 7 are fixedly installed with baffles 21.

[0019] Furthermore, an inlet pipe is fixedly installed at the upper end of the protective shell 7, and an outlet pipe is provided at the lower end of the protective shell 7. The protective shell 7 is connected to the water pipe 5 through the outlet pipe. A groove adapted to the sliding of the baffle 21 is machined on the partition 12. When the baffle 21 slides along the groove, it blocks half of the inlet pipe. By setting the baffle 21, the water flow distribution is adjusted by blocking half of the inlet pipe. With the alternating operation of the two sets of mounting brackets, maintenance can be achieved without stopping the machine.

[0020] Furthermore, the mounting bracket 10 is provided in two sets and is symmetrically distributed on both sides of the partition 12. The mounting bracket 10 not only provides stable support for the filter components, but also enables the maintenance and replacement of components during continuous operation of the equipment through the alternating maintenance design and adjustment of the baffle 21.

[0021] Furthermore, the outer ring of the threaded rod 15 is fitted with a synchronous pulley, and the outer ring of another set of synchronous pulleys is fitted with a first belt 22. Through the setting of the first belt 22, the first belt 22 links the two sets of threaded rods 15 through the synchronous pulley, ensuring that the slider 14 drives the cleaning roller 17 to move smoothly and synchronously along the guide rail 13, thus ensuring a uniform cleaning effect on the first screen 11.

[0022] Furthermore, a pressure pump 23 is installed at the upper end of the base 1. The pressure pump 23 is connected to the reverse osmosis tube 4 through a water pipe 5. The model of the pressure pump 23 is EC-204-600A. The pressure pump 23 provides power to the reverse osmosis tube 4 through the water pipe 5, ensuring that the inlet water pressure is stable and exceeds the osmotic pressure of the solution, providing the core driving force for water molecules to pass through the semi-permeable membrane to achieve separation and purification.

[0023] Furthermore, a drive motor 24 is provided at the upper end of the protective shell 7. The output end of the drive motor 24 is connected to the second belt 25 through a synchronous pulley. The second belt 25 is connected to the output end of the reducer 26 through another set of synchronous pulleys. The threaded rod 15 is connected to the other output end of the reducer 26 through a coupling. With the setting of the reducer 26, the reducer 26 can reduce the high-speed output speed of the drive motor 24 to the speed that matches the operation of the threaded rod 15, while increasing the torque to ensure that the slider 14 drives the cleaning roller 17 to move along the guide rail 13 at a stable speed.

[0024] Furthermore, a guide plate 27 is provided at the right end of the first screen 11, and a collection pool 28 is provided at the lower end of the guide plate 27. A second screen 29 is fixedly installed at the lower end of the mounting frame 10. Through the setting of the collection pool 28, the guide plate 27 receives the impurities on the first screen 11 that are cleaned by the cleaning roller 17, so as to realize the centralized collection and convenient cleaning of pollutants.

[0025] Working principle: The water to be treated enters the equipment through the inlet pipe at the upper end of the protective shell 7. It first flows through two sets of mounting frames 10 symmetrically distributed on both sides of the partition plate 12. It undergoes preliminary filtration through the first screen 11 at the upper end of the mounting frame 10, and then completes fine filtration through the second screen 29 at the lower end of the mounting frame 10. The filtered water flows into the water pipe 5 through the outlet pipe at the lower end of the protective shell 7. Under the power of the pressure pump 23 on the base 1, it is transported to the reverse osmosis pipe 4. The pressure provided by the pressure pump ensures that it exceeds the osmotic pressure of the inlet water, allowing water molecules to pass through the reverse osmosis membrane for purification. During equipment operation, the drive motor 24 provides power, which is transmitted to the reducer 26 through the second belt 25. The reducer adjusts the speed and drives the threaded rod 15 to rotate through the coupling. The first belt 22 passes through... Synchronous pulleys link two sets of threaded rods 15, causing slider 14 to move smoothly along guide rail 13. Connecting rod 16 at the lower end of slider 14 drives cleaning roller 17 to move synchronously. At the same time, gear 18 at the rear end of cleaning roller meshes with rack 20 on fixed plate 19 at the front end of partition 12, causing cleaning roller to rotate and thoroughly clean the first screen 11. The cleaned impurities fall into collection pool 28 through guide plate 27. When one set of mounting brackets 10 needs maintenance, the limit strip 9 at the front end of sliding protective shell 7 is unlocked, and the front handle of mounting bracket can be pulled out. During the process, sealing ring 8 adheres to the surface of mounting bracket to scrape off residual impurities and water. At the same time, baffle 21 on sliding partition 12 blocks the corresponding side liquid inlet pipe, so that water flows through only the other set of mounting brackets to continue filtering, achieving maintenance without stopping the machine.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
