Description

Technical Field

[0001] This utility model belongs to the technical field of reverse osmosis filter element structure, specifically relating to a reverse osmosis filter element structure with scale inhibitor. Background Technology

[0002] Reverse osmosis filter cartridges with scale inhibitors are one of the core components of reverse osmosis water treatment systems. They efficiently filter impurities in water and produce pure water while preventing and reducing scale deposition on the reverse osmosis membrane surface. Currently, the main consensus-based shortcomings of reverse osmosis filter cartridge structures are as follows: In the traditional reverse osmosis filter structure, the scale inhibitor added during use needs to reduce direct contact with the filter element, and the scale inhibitor is more likely to clog the filter pores of the reverse osmosis filter structure. The traditional reverse osmosis filter structure cannot more effectively reduce the contact between the scale inhibitor and the filter element, nor can it effectively prevent the scale inhibitor particles from clogging the filter pores, thus reducing the overall performance of the reverse osmosis filter structure. Utility Model Content

[0003] The purpose of this invention is to provide a reverse osmosis filter element structure with scale inhibitor, which aims to solve the problem that the traditional reverse osmosis filter element structure in the prior art cannot more effectively reduce the contact between the scale inhibitor and the filter element, and cannot effectively prevent the scale inhibitor particles from clogging the filter pores, thus reducing the overall performance of the reverse osmosis filter element structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A reverse osmosis filter element structure with scale inhibitor includes a shell, a central tube fixedly installed on the inner wall of the bottom end of the shell, a filter element body disposed on the outer side of the central tube, a storage box fixedly installed on the inner wall of the top end of the shell, a transition box connected to the bottom end of the storage box, a top cover threadedly connected to the top end of the storage box, a top ring fixedly installed on the outer side of the top cover, a top shell threadedly connected to the top end of the top ring, a water inlet pipe connected to the top end of the top shell, and multiple liquid outlet holes opened on the inner side wall of the storage box.

[0005] In a preferred embodiment of this invention, an outer ring is rotatably connected to the inner wall of the top cover, and a scraper is fixedly installed at the bottom end of the outer ring. The outer side of the scraper is slidably connected to the inner wall of the storage box.

[0006] In a preferred embodiment of this utility model, a rotating shaft is rotatably connected to the inner wall of the top of the top cover, and multiple fan blades are fixedly installed on the outer side of the rotating shaft. The outer sides of the multiple fan blades are fixedly connected to the inner side wall of the outer ring.

[0007] In a preferred embodiment of this invention, a support block is rotatably connected to the inner wall of the top of the storage box, and the inner wall of the top of the support block is movably connected to the bottom of the rotating shaft.

[0008] As a preferred embodiment of this utility model, the top of the top cover is provided with multiple water inlet holes.

[0009] As a preferred embodiment of this utility model, the bottom end of the transition box is provided with multiple water outlet holes.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1) The storage box can be used to store scale inhibitors, allowing the scale inhibitors to come into contact with water in advance and be mixed and transitioned through the transition box, reducing the direct contact between the scale inhibitors and the filter element. The fan blades, under the action of water flow, drive the outer ring to rotate inside the top cover, thereby allowing the scraper to rotate inside the storage box, which plays a role in mixing the scale inhibitors inside the storage box and preventing scale inhibitor particles from clogging the liquid outlet, thus improving the overall performance of the reverse osmosis filter element structure.

[0011] 2) The water inlet can filter large particles of impurities in the water entering the top shell. The connection between the top shell and the top ring makes it easier to disassemble and clean the impurities on the top cover. The connection between the top ring and the top cover also makes it easier to disassemble or install the top cover on the top of the storage box, making it more convenient to replace the scale inhibitor and improving the overall ease of use of the reverse osmosis filter element structure.

[0014] 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.

[0015] Please see Figure 1-5 The present invention provides the following technical solution: a reverse osmosis filter element structure with scale inhibitor, including a shell 1, a central tube 2 fixedly installed on the inner wall of the bottom end of the shell 1, a filter element body 3 arranged on the outer side of the central tube 2, a storage box 4 fixedly installed on the inner wall of the top end of the shell 1, a transition box 5 connected to the bottom end of the storage box 4, a top cover 6 threadedly connected to the top end of the storage box 4, a top ring 7 fixedly installed on the outer side of the top cover 6, a top shell 71 threadedly connected to the top end of the top ring 7, a water inlet pipe 72 connected to the top end of the top shell 71, and a plurality of liquid outlet holes 41 opened on the inner side wall of the storage box 4.

[0016] In practical use, when using this reverse osmosis filter structure, the water to be treated can be sent from the inlet pipe 72 to the inside of the top shell 71, and then flow to the inside of the top cover 6, so that it can continue to flow to the inside of the storage box 4. After mixing with the scale inhibitor inside the storage box 4, it flows again from the liquid outlet 41 on the inner wall of the storage box 4 into the transition box 5. This mixes the scale inhibitor with the water and reduces the direct contact between the scale inhibitor and the filter body 3, reducing the impact on the reverse osmosis effect of the filter body 3. After the mixed liquid flows to the position of the filter body 3, it can be treated by reverse osmosis, so that the treated water can flow from the central pipe 2 to the bottom, improving the overall performance of the reverse osmosis filter structure. The top shell 71 and the top ring 7 can be disassembled for the removal of large particles of impurities. Similarly, the top ring 7 can drive the top cover 6 to rotate and be disassembled at the top of the storage box 4, making it easier to replace the scale inhibitor and improving the convenience of using the overall reverse osmosis filter structure.

[0017] Preferably, an outer ring 61 is rotatably connected to the inner wall of the top cover 6, and a scraper 62 is fixedly installed at the bottom end of the outer ring 61. The outer side of the scraper 62 is slidably connected to the inner wall of the storage box 4.

[0018] In practical use, when water flows inside the top cover 6, the outer ring 61 rotates inside the top cover 6, thereby causing the outer ring 61 to drive the scraper 62 to rotate inside the storage box 4, scraping the inner wall of the storage box 4 and preventing the scale inhibitor particles inside the storage box 4 from clogging the liquid outlet 41.

[0019] Preferably, a rotating shaft 63 is rotatably connected to the inner wall of the top of the top cover 6, and multiple fan blades 64 are fixedly installed on the outer side of the rotating shaft 63. The outer side of the multiple fan blades 64 is fixedly connected to the inner side wall of the outer ring 61.

[0020] In practical use, when the liquid flows from the top of the top cover 6 to the inside, the water flow can act on the fan blades 64, causing the fan blades 64 to drive the rotating shaft 63 to rotate between the top cover 6 and the storage box 4, and the outer ring 61 to rotate inside the top cover 6, which in turn can drive the scraper 62 to rotate inside the storage box 4.

[0021] Preferably, a support block 42 is rotatably connected to the top inner wall of the storage box 4, and the top inner wall of the support block 42 is movably connected to the bottom end of the rotating shaft 63.

[0022] In practical use, the rotating shaft 63 can rotate on the top of the storage box 4 through the support block 42. When the top cover 6 is separated from the storage box 4, the rotating shaft 63 can be directly separated from the storage box 4 through the top cover 6, so that it can be used to replace the scale inhibitor inside the storage box 4. During installation, the storage box 4 and the top cover 6 can be installed through the connection between the rotating shaft 63 and the support block 42. Similarly, the top ring 7 can fit against the outer shell 1.

[0023] Preferably, the top of the top cover 6 has multiple water inlet holes 65.

[0024] In practical use, the water inlet 65 at the top of the top cover 6 can be used to filter large particulate impurities in the water entering the top shell 71.

[0025] Preferably, the bottom of the transition box 5 is provided with multiple water outlet holes 51.

[0026] In practical use, the bottom of the transition box 5 can more evenly input the mixed water and scale inhibitor into the filter body 3.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
