Abstract
Description
Technical Field
[0001] This utility model belongs to the field of filter element technology, and in particular relates to an anti-erosion filter element. Background Technology
[0002] A filter element is a core component used to filter impurities from fluids (such as air or water). Its function is to remove particulate matter, pollutants, and harmful substances (such as dust, bacteria, heavy metals, chlorine, etc.) from the medium through physical interception, adsorption, or chemical reactions, thereby purifying the fluid and improving its purity and safety. It is widely used in equipment such as air purifiers, water purifiers, and car filters. It is a key component to ensure the normal operation of the equipment and the health of users. Regularly replacing the filter element can ensure filtration efficiency and maintain the best performance.
[0003] Existing filter cartridges still have some problems during use. For example, during filtration, the impact force generated by the flow of wastewater will directly act on the surface of the filter cartridge, causing the filter cartridge to deform, break or delaminate, thereby reducing the filtration accuracy and service life. At the same time, high-speed water flow may also carry particulate matter to cause erosion and wear on the inner wall of the filter cartridge, thereby further affecting the filtration effect.
[0004] Therefore, we provide an anti-erosion filter element to solve the above-mentioned problems. Utility Model Content
[0005] The purpose of this utility model is to provide an anti-erosion filter element that can prevent the impact of water flow on the filter element, thus solving the problem that filter elements in the prior art are easily damaged by the impact of water flow when filtering wastewater.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
[0007] This utility model relates to an anti-erosion filter element, comprising an anti-erosion shell, a fixed frame fixedly connected to the bottom of the inner cavity of the anti-erosion shell, a guide plate fixedly connected inside the fixed frame, a spiral guide groove inserted inside the anti-erosion shell, a placement groove opened inside the anti-erosion shell, a filter element body disposed inside the placement groove, horizontal plates fixedly connected to both sides of the surface of the anti-erosion shell, a sliding rod slidably connected inside the horizontal plate, a spring sleeved on the bottom of the surface of the sliding rod, a fixed plate fixedly connected to the top of the sliding rod, and a protective cover provided on the top of the anti-erosion shell.
[0008] The present invention is further configured such that a fixing groove is provided on both sides of the top of the protective cover, and the fixing plate is slidably connected to the inside of the fixing groove.
[0009] The present invention is further configured such that guide blocks are fixedly connected to both sides of the inner wall of the placement groove, and guide grooves are opened on both sides of the filter element body, and the filter element body is slidably connected to the surface of the guide blocks through the guide grooves.
[0010] The present invention is further configured such that an anti-detachment plate is fixedly connected to the bottom of the slide rod, and the top and bottom of the spring are respectively fixedly connected to the bottom of the cross plate and the top of the anti-detachment plate.
[0011] The present invention is further provided that a sealing ring is fixedly connected to the bottom of the inner cavity of the protective cover, and the sealing ring is used to seal the protective cover.
[0012] The present invention is further configured such that the anti-impact shell is made of stainless steel, and the anti-impact shell is used to directly withstand the impact of high-speed fluid.
[0013] The present invention is further configured such that the filter element body is made of composite ceramic, and the filter element body is used to filter wastewater.
[0014] The present invention has the following beneficial effects.
[0015] 1. This utility model, through the guide plate and spiral guide groove set inside the anti-impact shell, enables the water flow to be initially diverted by the guide plate after entering the filter element body, thereby reducing the initial impact force. Subsequently, the spiral guide groove forms a vortex motion, converting the linear impact into rotational kinetic energy, and evenly dispersing the water flow pressure. The cooperation between the guide plate and the spiral guide groove effectively reduces the direct impact of high-speed water flow on the filter element body, prevents the filter material from deforming, breaking or delaminating, significantly extends the service life of the filter element and maintains stable filtration accuracy.
[0016] 2. This utility model ensures the stable positioning of the filter element body by precisely sliding the guide groove and the guide block in the placement groove, avoiding displacement caused by water flow impact. The slide rod and fixing plate can be quickly engaged with the fixing groove by the spring and sealed with the sealing ring, which not only ensures the firmness of the installation, but also facilitates the disassembly, replacement or cleaning of the filter element, greatly improving maintenance efficiency. At the same time, the combination of stainless steel anti-impact shell and composite ceramic filter element body further enhances the corrosion resistance and erosion resistance of the overall structure, preventing the impact of water flow from affecting the filter element body.
[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Example 1
[0027] Please see Figures 1-5 This utility model relates to an anti-erosion filter element, comprising an anti-erosion shell 1, which prevents water flow from directly impacting the filter element body 6 and thus damaging the filter element. A fixing frame 2 is fixedly connected to the bottom of the inner cavity of the anti-erosion shell 1, which can fix a flow guide plate 3. The flow guide plate 3 is fixedly connected inside the fixing frame 2, which can initially disperse the water flow. A spiral flow guide groove 4 is embedded inside the anti-erosion shell 1, which can effectively guide the water flow along a spiral path, transforming the original linear impact force into a rotating upward vortex, thereby significantly reducing the direct impact of water flow on the filter element body 6. The anti-impact shell 1 has an internal placement groove 5 for storing the filter element body 6. The filter element body 6 filters the water source. Horizontal plates 7 are fixedly connected to both sides of the surface of the anti-impact shell 1. Sliding rods 8 are slidably connected inside the horizontal plates 7. Springs 9 are sleeved on the bottom of the surface of the sliding rods 8. The springs 9 provide tension to the fixing plate 10, thereby fixing the protective cover 11. The fixing plate 10 is fixedly connected to the top of the sliding rods 8. The protective cover 11 is set on the top of the anti-impact shell 1. The protective rod can fix the filter element body 6 and facilitate subsequent filter element replacement.
[0028] Example 2
[0029] Please see Figures 1-5 Based on the embodiment, the protective cover 11 has fixing grooves 12 on both sides of the top, and the fixing plate 10 is slidably connected to the inside of the fixing groove 12. The fixing groove 12 can easily fix the protective cover 11 to the fixing plate 10. The inner wall of the placement groove 5 is fixedly connected to both sides of the guide block 13. The guide block 13 can limit the filter element body 6. The filter element body 6 has guide grooves 14 on both sides. The filter element body 6 is slidably connected to the surface of the guide block 13 through the guide groove 14. The bottom of the slide rod 8 is fixedly connected to the anti-detachment plate 15. The anti-detachment plate 15 can support the spring 9. The top and bottom of the spring 9 are fixedly connected to the bottom of the horizontal plate 7 and the top of the anti-detachment plate 15, respectively. The bottom of the inner cavity of the protective cover 11 is fixedly connected to the sealing ring 16. The sealing ring 16 is used to seal the protective cover 11. The anti-impact shell 1 is made of stainless steel. The anti-impact shell 1 is used to directly withstand the impact of high-speed fluid. The filter element body 6 is made of composite ceramic. The filter element body 6 is used to filter wastewater.
[0030] The working principle of this utility model is as follows: When it is necessary to disperse the water flow and reduce its impact on the filter element body 6, the water flow enters the filter element through the inlet of the filter element body 6. After entering the inlet, the water flow first passes through the guide plate 3 in the fixed frame 2 for initial diversion and buffering, effectively reducing the initial impact force of the water flow. Then, the water flow enters the spiral guide groove 4 area. When passing through the spiral guide groove 4, the water flow forms an upward vortex motion, thereby converting the linear impact force into rotational kinetic energy, making the water flow evenly dispersed and reducing the flow velocity. The uniform water flow distribution avoids the local high pressure scouring of the filter element. Finally, the buffered and optimized water flow smoothly passes through the filter element body 6 for filtration, which not only protects the filter element body 6 but also ensures filtration efficiency.
[0031] When the filter body 6 needs to be installed, the user pulls the fixing plate 10, which moves the slide bar 8. The slide bar 8 moves the anti-detachment plate 15, which compresses the spring 9 during the movement. Then the user rotates the fixing plate 10 to make it flush with the fixing groove 12, and then releases the fixing plate 10. At this time, the spring 9 will pull the fixing plate 10 back to its original position through its own elasticity, so that the fixing plate 10 moves into the fixing groove 12, thereby fixing the protective cover 11, thus achieving the purpose of installing the filter body 6.
[0032] When it is necessary to disassemble the filter body 6 for replacement or maintenance, the user only needs to reverse the above steps. First, remove the fixing plate 10 from the fixing groove 12, then pull the fixing plate 10 to move the slide bar 8 and the anti-detachment plate 15. The spring 9 will be squeezed again. Then rotate the fixing plate 10 to make it offset from the installation position of the filter body 6. At this time, the protective cover 11 and the filter body 6 can be easily removed.
[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
