Description

Technical Field

[0001] The utility model relates to the technical field of filter elements, in particular to a composite filter element for water filtration. Background Art

[0002] A filter element is a professional device used for filtering and purification. It is mainly used in oil filtration, air filtration, water filtration and other industries. It separates solid particles from liquids or gases through filters of certain specifications to protect the normal operation of equipment or keep the air clean.

[0003] A Chinese patent discloses a large-flow industrial condensate filter element (authorization announcement number CN221358894U). The patented technology rotates bevel gear 2 to drive the spiral rod to rotate, thereby driving the bottom ring block to move upward, driving the filter element assembly and the splicing device to move upward, and when the bottom ring block moves upward, the plug rod slides out of the cavity, and the spring drives the limit assembly to move toward the middle of the bottom ring block, thereby exposing more slag troughs, so that impurities adhering to the first filter screen are blocked by the slag trough when they rise and fall, and fall into the inside of the slag trough, and are finally cleaned uniformly.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: after long-term use, the existing filter element may cause the water flow to weaken or stop flowing due to the accumulation of impurities, and needs to be regularly inspected and cleaned or replaced. However, in the prior art, when replacing the filter element, the replacement process is relatively cumbersome and after installation, it is easy to become loose due to the impact of water flow, affecting the use effect. Utility Model Content

[0022] Now, with reference to the accompanying drawings and preferred embodiments, the present utility model will be further described in detail. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0023] Refer to Figure 1 - Figure 4 As shown in the figure, the present utility model provides a technical solution: a composite filter element for water filtration, including a filter body 1, a top cover 2 is installed at the top of the filter body 1, four filter element housings 3 are installed inside the filter body 1, a first filter element 4, a second filter element 5, a third filter element 6 and a fourth filter element 7 are sequentially installed inside the filter element housing 3, a traction groove 8 is opened at the front end inside the filter element housing 3, a traction block 9 is slidably connected inside the traction groove 8, a connecting plate 10 is installed on one side of the traction block 9, a groove 11 is opened at the top of the connecting plate 10, two snaps 12 are slidably connected inside the groove 11, the bottom end of the first filter element 4 is fixedly connected with a mounting plate 13, two card slots 14 are opened on the surface of the mounting plate 13, sliding grooves 15 are opened on both sides of the connecting plate 10, a sliding rod 16 is slidably connected inside the sliding groove 15, and the end of the sliding rod 16 away from the connecting plate 10 is fixedly connected with a push-pull plate 17. When the staff needs to replace the first filter element 4, the traction block 9 is pulled out, so that the connecting plate 10 drives the first filter element 4 to move out of the filter element housing 3. At this time, the push-pull plate 17 is pressed to drive the sliding rod 16 to push the snap 12, so that the snap 12 is disengaged from the card slot 14, and the first filter element 4 is released from the limit. At this time, a new first filter element 4 is connected with the snap 12 through the card slot 14. After the connection is completed, the spring in the groove 11 will firmly fix the snap 12 in the card slot 14, so as to achieve the quick installation and disassembly of the first filter element 4, and the installation has a relatively stable fixing effect, effectively improving the replacement efficiency and installation stability during use.

[0024] Refer to Figure 5As shown in the figure, in this implementation: on both sides inside the traction groove 8, first sliding grooves 18 are provided. On both sides of the traction block 9, first sliding blocks 19 are fixedly connected. The inside of the first sliding groove 18 is slidably connected to the first sliding block 19. Through the arrangement of the first sliding groove 18 and the first sliding block 19, when the traction block 9 moves inside the traction groove 8, stable limitation can be formed, thereby realizing the stable movement of the traction block 9.

[0025] Refer to Figure 5 As shown in the figure, in this implementation: at the front end and the rear end inside the slot 11, second sliding grooves 20 are provided. At the front end and the rear end of the buckle 12, second sliding blocks 21 are fixedly connected. The inside of the second sliding groove 20 is slidably connected to the second sliding block 21. Through the arrangement of the second sliding groove 20 and the second sliding block 21, the buckle 12 can move more stably inside the slot 11, thereby effectively improving the clamping stability when the buckle 12 is clamped and enhancing the fixing effect.

[0026] Refer to Figure 5 As shown in the figure, in this implementation: a limiting spring 22 is slidably connected to the surface of the sliding rod 16. One end of the limiting spring 22 close to the connecting plate 10 is fixedly connected to the connecting plate 10, and the end of the limiting spring 22 far from the connecting plate 10 is fixedly connected to the push-pull plate 17. Through the arrangement of the limiting spring 22, after the push-pull plate 17 is pressed, the sliding rod 16 will automatically rebound due to the elastic force stored in the limiting spring 22, thereby realizing the automatic reset of the push-pull plate 17 after being pressed and enhancing the use convenience.

[0027] Refer to Figure 3 As shown in the figure, in this implementation: a reset spring 23 is fixedly connected to the bottom end of the traction block 9, and the bottom end of the reset spring 23 is fixedly connected to the inside of the traction groove 8. Through the arrangement of the reset spring 23, after the traction block 9 moves, the pulling force stored in the reset spring 23 is released to drive the traction block 9 to quickly reset, thereby achieving the quick reset of the traction block 9 after moving and further enhancing the use convenience.

[0028] Refer to Figure 2 As shown in the figure, in this implementation: anti-pollution coatings are provided on the surfaces of the first filter element 4, the second filter element 5, the third filter element 6, and the fourth filter element 7. By setting a special protective layer for resisting pollution, the anti-pollution performance of the filter element during actual use can be significantly improved. This anti-pollution layer can effectively block and filter out various pollutants, thereby extending the service life of the filter element and ensuring that its filtering effect is always in the best state.

[0029] Refer to Figure 2As shown, in this embodiment: The main materials of the first filter element 4, the second filter element 5, the third filter element 6 and the fourth filter element 7 are all diatomaceous earth. Diatomaceous earth is a natural porous material with extremely high adsorption capacity and filtration accuracy, so it has been widely used in the filtration system. This filter element material can not only effectively remove impurities, suspended solids and some harmful substances in water, but also keep the water flow smooth and extend the service life of the filter element.

[0030] Refer to Figure 2 As shown, in this embodiment: The interiors of the first filter element 4, the second filter element 5, the third filter element 6 and the fourth filter element 7 are all multi-stage gradient filtration structures. By setting the filter element as a multi-stage gradient filtration structure, this structural design enables the filter element to gradually remove impurities and particulate matters of different sizes during the filtration process. This multi-stage gradient filtration structure not only improves the filtration accuracy, but also extends the service life of the filter element, ensuring the continuity and stability of the filtration effect.

[0031] Working principle: When the staff needs to replace the first filter element 4, pull out the traction block 9, so that the connecting plate 10 drives the first filter element 4 to move out from the inside of the filter element housing 3. At this time, press the push-pull plate 17 to drive the sliding rod 16 to push the buckle 12, so that the buckle 12 is disengaged from the card slot 14, and the first filter element 4 is released from the limit. Then, the new first filter element 4 is clamped with the buckle 12 through the card slot 14. After the clamping is completed, the spring in the slot 11 will firmly fix the buckle 12 in the card slot 14, so as to achieve the quick installation and disassembly of the first filter element 4, and there is a relatively firm fixing effect after installation, effectively improving the replacement efficiency and installation stability during use. Through the setting of the first chute 18 and the first slider 19, when the traction block 9 moves inside the traction groove 8, a firm limit can be formed, so as to realize the stable movement of the traction block 9. Through the setting of the second chute 20 and the second slider 21, the buckle 12 can move more stably inside the slot 11, thus effectively improving the clamping stability of the buckle 12 during clamping and enhancing the fixing effect. Through the setting of the limit spring 22, after the push-pull plate 17 is pressed, the sliding rod 16 will automatically rebound due to the elastic force stored in the limit spring 22, so as to realize the automatic reset of the push-pull plate 17 after being pressed, improving the use convenience. Through the setting of the return spring 23, after the traction block 9 moves, the pulling force stored in the return spring 23 is released to drive the traction block 9 to quickly return, so as to achieve the quick return of the traction block 9 after moving, further improving the use convenience. By setting a special protective layer for resisting pollution, the anti-pollution performance of the filter element during actual use can be significantly improved. This anti-pollution layer can effectively block and filter out various pollutants, thereby extending the service life of the filter element and ensuring that its filtering effect is always in the best state. Diatomite is a natural porous material with extremely high adsorption capacity and filtration accuracy, so it has been widely used in the filtration system. This filter element material can not only effectively remove impurities, suspended solids and some harmful substances in water, but also keep the water flow smooth and extend the service life of the filter element. Through the setting of the filter element with a multi-stage gradient filtration structure, this structural design enables the filter element to gradually remove impurities and particulate matters of different sizes during the filtration process. This multi-stage gradient filtration structure not only improves the filtration accuracy, but also extends the service life of the filter element, ensuring the continuity and stability of the filtration effect.
