Description

Technical Field

[0001] This utility model relates to the field of filter element cleaning, and in particular to a filter element cleaning device for reverse osmosis water inlet components. Background Technology

[0002] Filter cartridge cleaning refers to the process of removing impurities and contaminants (such as particles, colloids, microorganisms, organic matter, etc.) trapped on and inside the filter cartridge through physical, chemical, or mechanical methods, thereby restoring the filter cartridge's filtration performance. Its purpose is to extend the filter cartridge's lifespan, maintain system filtration efficiency, and ensure that water or fluid quality meets usage requirements.

[0003] In existing reverse osmosis feed water components, cleaning the filter element first requires shutting down the system and depressurizing. After closing the inlet valve and disconnecting the power, open the vent valve to release the internal pressure of the system. Next, wearing protective equipment, use special tools to disassemble the filter housing and separate the security filter cover from the filter housing. Then, remove the filter element. If it can be washed, first rinse it with clean water from the inside out to remove loose dirt. If necessary, use a suitable alkaline or acidic cleaning agent for chemical cleaning. Immerse the filter element in the cleaning solution prepared according to the instructions for an appropriate time, shaking it appropriately during the process. After chemical cleaning, rinse the filter element thoroughly with plenty of clean water to ensure no cleaning agent residue remains. Finally, carefully check the integrity and cleanliness of the filter element. Once confirmed to be correct, reassemble it into the component in the reverse order of disassembly.

[0004] In existing reverse osmosis feed water component filter element cleaning technologies, most adopt a single straight-line rinsing or simple scraping method. Such cleaning methods not only have a single cleaning path and can only make a single contact with the filter element surface, but also make it difficult to break the adhesion between impurity particles, resulting in stubborn impurities remaining. Therefore, a filter element cleaning device for reverse osmosis feed water components is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a filter cartridge cleaning device for a reverse osmosis water inlet assembly, comprising a filter cylinder, wherein a cleaning mechanism and a fitting mechanism are provided on the inner wall of the filter cylinder, the cleaning mechanism includes a filter cartridge, the top and bottom ends of which are fixedly connected to the inner wall of the filter cylinder, a support ring block is slidably connected to the outer wall of the filter cartridge, a cleaning ring frame is rotatably connected to the inner wall of the support ring block, a worm gear ring is fixedly connected to the outer wall of the cleaning ring frame, a worm is rotatably connected to the inner wall of the support ring block, the outer wall of the worm meshes with the outer wall of the worm gear ring, gears are fixedly connected to both ends of the worm, a toothed plate is fixedly connected to the inner wall of the filter cylinder, the outer wall of the gear meshes with the outer wall of the toothed plate, a lifting block is fixedly connected to the outer wall of the support ring block, the outer wall of the lifting block is slidably connected to the inner wall of the filter cylinder, and a screw is threadedly connected to the inner wall of the lifting block via a threaded sleeve.

Detailed Implementation

[0033] 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.

[0034] Reference Figures 4-6 The present invention provides an embodiment of a filter element cleaning device for a reverse osmosis water inlet assembly, comprising a filter cylinder 1, a cleaning mechanism 2 and a fitting mechanism 3 provided on the inner wall of the filter cylinder 1, the cleaning mechanism 2 including a filter element 211, the top and bottom ends of the filter element 211 being fixedly connected to the inner wall of the filter cylinder 1, the filter element 211 being used to filter the water entering the filter cylinder 1 and intercept impurities in the water, a support ring block 212 being slidably connected to the outer wall of the filter element 211, the support ring block 212 providing installation support for the cleaning ring frame 213 and being able to rise and fall along the outer wall of the filter element 211, the inner wall of the support ring block 212 being rotatably connected to the cleaning ring frame 213, the cleaning ring frame 213 driving the cleaning block 312 to rotate, cleaning the filter element 211, the outer wall of the cleaning ring frame 213 being fixedly connected to a worm gear ring 214, the worm gear ring 214 cooperating with the worm 215 to transmit the rotation of the worm 215 to the cleaning ring frame 213, the inner wall of the support ring block 212 being fixedly connected to the cleaning ring frame 213. A worm gear 215 is rotatably connected. The worm gear 215 rotates under the drive of the gear 216, thereby driving the worm wheel ring 214. The outer wall of the worm gear 215 meshes with the outer wall of the worm wheel ring 214. Gears 216 are fixedly connected to both ends of the worm gear 215. The gears 216 mesh with the toothed plate 217, converting the lifting motion of the support ring block 212 into the rotation of the worm gear 215. The toothed plate 217 is fixedly connected to the inner wall of the filter cylinder 1. The toothed plate 217 cooperates with the gear 216 to provide rotational power for the gear 216. A lifting block 218 is fixedly connected to the outer wall of the support ring block 212. The lifting block 218 rises and falls with the rotation of the screw 219, driving the support ring block 212 to move up and down. The outer wall of the lifting block 218 is slidably connected to the inner wall of the filter cylinder 1. The inner wall of the lifting block 218 is threadedly connected to the screw 219 through a threaded sleeve. When the screw 219 rotates, the lifting block 218 rises and falls along the inner wall of the filter cylinder 1 through the threaded transmission.

[0035] Reference Figures 1-3The cleaning mechanism 2 also includes a motor 220, the bottom of which is fixedly connected to the top of the filter cylinder 1. The output end of the motor 220 is fixedly connected to the top of the screw 219. The motor 220 provides power to the entire cleaning mechanism 2 and drives the screw 219 to rotate. The cleaning mechanism 2 also includes a water inlet 221, which is located on the outer wall of the filter cylinder 1. The water inlet 221 is the channel for the water to be filtered to enter the filter cylinder 1. The cleaning mechanism 2 also includes a drain outlet 222, which is located at the bottom of the filter cylinder 1. The interior of the drain outlet 222 is connected to the interior of the filter element 211. The drain outlet 222 is used to discharge the clean water filtered by the filter element 211. The cleaning mechanism 2 also includes a waste discharge port 223, which is located at the bottom of the filter cylinder 1. The waste discharge port 223 is used to discharge the impurities generated when cleaning the filter element 211.

[0036] Reference Figure 7 The bonding mechanism 3 includes a limiting groove 311, which is formed on the inner wall of the cleaning ring frame 213. The limiting groove 311 restricts the sliding direction of the cleaning block 312, so that it can only move along a specific trajectory. The bonding mechanism 3 also includes a cleaning block 312, the bottom of which is slidably connected to the inner wall of the limiting groove 311. The cleaning block 312 directly contacts the outer wall of the filter element 211 to clean impurities on the surface of the filter element 211. The bonding mechanism 3 also includes a spring 313, one end of which is fixedly connected to the inner wall of the cleaning ring frame 213, and the other end of which is fixedly connected to the outer wall of the cleaning block 312. The spring 313 uses its elasticity to keep the cleaning block 312 always in contact with the outer wall of the filter element 211, ensuring the cleaning effect.

[0037] Working principle: When the filter element 211 needs to filter water, the water to be filtered is added into the water filter cylinder 1 through the inlet 221. The filter element 211 can filter impurities in the water. The water after filtering impurities can be discharged through the drain outlet 222. When the filter element 211 needs to be cleaned, the motor 220 is started, so that the output end of the motor 220 drives the fixedly connected screw 219 to rotate. The screw 219 drives the threaded sleeve connected to the outer wall to move. The threaded sleeve drives the lifting block 218 fixedly connected to the outer wall to rise and fall. The lifting block 218 drives the support ring block 212 fixedly connected to the side wall to rise and fall. The support ring block 212 can drive the cleaning block 312 to clean the filter element 211.

[0038] When the support ring 212 is raised and lowered, the gear 216 and the toothed plate 217 are meshed, which allows the gear 216 to rotate. This, in turn, drives the worm gear 215, which is fixedly connected to the inner wall of the gear 216, to rotate. This, in turn, drives the worm wheel ring 214, which is meshed with the outer wall of the worm gear 215, to rotate. The worm wheel ring 214 then drives the cleaning ring frame 213, which is fixedly connected to the inner wall, to rotate. The cleaning ring frame 213 can drive the cleaning block 312 to rotate, thus forming a spiral cleaning path. The spiral trajectory allows the cleaning block 312 to perform multiple alternating cleanings on each area of ​​the filter element 211 surface. When the cleaning block 312 is cleaning the filter element 211, the elastic force of the spring 313 can always push the cleaning block 312 to adhere to the outer wall of the filter element 211, thereby ensuring the cleaning effect.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
