Description

Technical Field

[0001] This invention relates to the field of water purification filter technology, and in particular to a multi-stage filtration carbon rod filter. Background Technology

[0002] Activated carbon filter cartridges are made from high-quality fruit shell carbon and coal-based activated carbon, supplemented with food-grade binders, using high-tech technology and special processes. They integrate adsorption, filtration, interception, and catalysis, effectively removing organic matter, residual chlorine, and other radioactive substances from water, and also have the effects of decolorization and odor removal. During long-term use, various impurities, organic matter and other particulate matter will gradually accumulate on the surface and inside of the activated carbon filter. These substances may partially block the pores of the activated carbon, causing water to encounter more resistance when it flows through, thereby reducing the water permeability. When the water permeability is too low, the activated carbon filter needs to be replaced. However, the replaced carbon filter element still has a certain filtration effect that is not utilized, thus preventing the utilization rate of the carbon filter element from being further improved. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a multi-stage filtration carbon rod filter element. By setting multiple carbon rod filter elements, the number of carbon rod filter elements participating in the filtration work can be adjusted under different water pressures to improve the utilization rate of the carbon rod filter element.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: A multi-stage filtration carbon rod filter element includes a filter element housing, the bottom of which is threadedly connected to a bottom cover, and further includes: The filter cartridge housing contains several carbon columns arranged sequentially from top to bottom. The number of carbon columns participating in filtration is controlled by adjusting the water pressure input into the filter cartridge housing. When the carbon columns are filtering, they are rotated to reduce the probability of the carbon column surface being blocked. The carbon column is equipped with an adjusting cylinder. The position of the adjusting cylinder is adjusted by the different water pressures inside the filter cartridge shell, so that the adjusting cylinder constrains the water input into the filter cartridge shell to the area where some of the carbon columns are located. The filter cartridge housing is threadedly connected to a top cover, which is used to remove and place the filter cartridge inside the filter cartridge housing and to maintain the sealed state inside the filter cartridge housing.

[0005] Furthermore, the filter cartridge shell is fixedly connected to a first isolation cylinder by several connecting blocks. The bottom surface of the first isolation cylinder is fixedly connected to a placement cylinder. The surface of the placement cylinder is uniformly provided with a first water permeable groove.

[0008] Furthermore, an isolation ring is fixedly connected to the first circular groove on the surface of the charcoal box, and a first sealing ring is fixedly connected inside the isolation ring. The adjusting cylinder is slidably connected to several of the first sealing rings.

[0009] Furthermore, a protective spherical shell is fixedly connected to the surface of each telescopic section of the multi-section telescopic rod near the top position, and a magnetic ring is fixedly connected inside the protective spherical shell. There is a repulsive force between any adjacent magnetic rings on the same surface of the multi-section telescopic rod.

[0010] Furthermore, a second water-permeable groove is formed on the surface of the carbon column, and a water-guiding plate is provided inside the second water-permeable groove. The water-guiding plate is fixedly connected to the carbon box and abuts against the carbon column.

[0011] Furthermore, a connecting pipe is fixedly connected to the fifth circular groove starting from the surface of the top cover, and an isolation inner cover is provided at the bottom of the connecting pipe. The connecting pipe is fixedly connected to the sixth circular groove opened on the surface of the isolation inner cover, and a sealing sheet is fixedly connected to the bottom surface of the isolation inner cover.

[0026] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0027] like Figures 1 to 10 As shown, an embodiment of the present invention provides a multi-stage filtration carbon rod filter element, including a filter element shell 101, a bottom cover 102 threadedly connected to the bottom of the filter element shell 101, and further including: The filter cartridge housing 101 has several carbon columns 210 arranged from top to bottom inside. The number of carbon columns 210 participating in filtration is controlled by adjusting the water pressure inside the filter cartridge housing 101. When the carbon columns 210 are filtering, they are rotated to reduce the probability of the carbon column 210 surface being blocked. The carbon column 210 is equipped with an adjusting cylinder 219. By adjusting the water pressure inside the filter cartridge 101, the position of the adjusting cylinder 219 is adjusted so that the adjusting cylinder 219 can constrain the water entering the filter cartridge 101 to the area where some of the carbon columns 210 are located. The filter element housing 101 is threadedly connected to a top cover 201, which is used to take out and put in the filter element inside the filter element housing 101 and to maintain the sealed state inside the filter element housing 101.

[0028] In this embodiment of the invention, the filter cartridge shell 101 is provided with five carbon columns 210 inside. The water pressure entering the filter cartridge shell 101 is divided into three levels: low, medium, and high. During water filtration, if the water pressure entering the filter cartridge shell 101 is low, the regulating cylinder 219 directs the water into the area of ​​the uppermost carbon column 210, so the uppermost carbon column 210 is mainly used for filtration. When the water pressure entering the filter cartridge shell 101 gradually increases to medium, the regulating cylinder 219 gradually moves downward, causing the first and second carbon columns at the top to be directed downward. Each carbon column 210 participates in the filtration process. When the water pressure entering the filter cartridge housing 101 continues to increase to a high water pressure, the first, second, and third carbon columns 210 located at the top participate in the filtration process. During this process, the carbon columns 210 located at the top participate in the filtration process for a longer time, while the carbon columns 210 located at the bottom participate in the filtration process for a relatively shorter time. When the filtration effect of the carbon columns 210 located at the top gradually becomes blocked, while keeping the water pressure entering the filter cartridge housing 101 constant, the water pressure inside the filter cartridge housing 101 will increase, forcing the regulating cylinder 219 to move downward, thereby allowing the carbon columns 210 located at the bottom to participate in the filtration process.

[0029] When high water pressure is introduced into the filter cartridge housing 101, as the upper carbon column 210 gradually becomes clogged, the regulating cylinder 219 moves downward under the gradually increasing water pressure above it, so that the fourth carbon column 210 from top to bottom participates in the filtration work. When the fifth carbon column 210 participates in the filtration work, it indicates that the uppermost carbon column 210 needs to be replaced. In order to make fuller use of the filtration effect of the uppermost carbon column 210, when the regulating cylinder 219 moves to the lowest position, the uppermost carbon column 210 is removed, and the replaced carbon column 210 is placed at the bottom of the five carbon columns 210. Repeating the above steps can make fuller use of each carbon column 210. When the carbon column 210 is filtering, rotating the carbon column 210 can make the water contact the surface of the carbon column 210 more evenly, which is beneficial to improving the adsorption efficiency of the carbon column 210. At the same time, rotation can help loosen and disperse impurities attached to the surface of the carbon column 210, reduce the possibility of local clogging, extend the service life of the filter element, and maintain a high water permeability.

[0030] like Figure 2 As shown, the filter cartridge shell 101 is fixedly connected to a first isolation cylinder 203 by several connecting blocks. The bottom surface of the first isolation cylinder 203 is fixedly connected to a placement cylinder 205. The surface of the placement cylinder 205 is evenly provided with a first water permeable groove 206. The surface of the placement cylinder 205 is fixedly connected to a second isolation sleeve 204.

[0031] The filter housing 101 is equipped with a primary carbon rod filter element. The inner wall of the primary carbon rod filter element is in contact with the surface of the isolation tube 222, the bottom surface of the first isolation cylinder 203 and the inner wall of the bottom cover 102. The surface of the primary carbon rod filter element is not in contact with the filter housing 101. The first small hole opened on the surface of the isolation tube 222 is located inside the primary carbon rod filter element.

[0032] The surface of the second isolation sleeve 204 is provided with a high-efficiency carbon rod filter element, the inner wall of the high-efficiency carbon rod filter element abuts against the second isolation sleeve 204, and the surface of the high-efficiency carbon rod filter element abuts against the inner wall of the first isolation cylinder 203.

[0033] The interior of the placement cylinder 205 is equipped with several charcoal boxes 207. The charcoal columns 210 are fixedly connected to the corresponding charcoal boxes 207. The second circular groove on the bottom surface of the first isolation cylinder 203 is fixedly connected to an isolation tube 222. Several first small holes are evenly opened on the surface of the isolation tube 222 near the bottom.

[0034] In this embodiment of the invention, after water enters the interior of the filter cartridge shell 101, it first flows from the surface of the first isolation cylinder 203 to the bottom of the filter cartridge shell 101, so that it can pass through the primary carbon rod filter. After passing through the primary carbon rod filter, the water enters the interior of the placement cylinder 205 through the first small hole on the surface of the isolation tube 222. After being filtered by the carbon column 210 in the carbon box 207, it enters the placement cylinder 205 and the second isolation sleeve 204 through the first water permeable groove 206, and flows out from the bottom of the second isolation sleeve 204, so that the water can pass through the high-efficiency carbon rod filter.

[0035] like Figures 1 to 10 As shown, an isolation plate 218 is fixedly connected to the inner wall of the isolation tube 222. Several multi-section telescopic rods 216 are arranged in a ring array on the surface of the isolation plate 218. An adjusting cylinder 219 is located inside the placement cylinder 205. The two ends of the multi-section telescopic rods 216 are fixedly connected to the adjusting cylinder 219 and the multi-section telescopic rods 216, respectively. The adjusting cylinder 219 is located inside several carbon columns 210. A flexible hose 217 is fixedly connected between the isolation plate 218 and the adjusting cylinder 219. The two ends of the flexible hose 217 are located in the third circular groove opened on the surface of the isolation plate 218 and the fourth circular groove opened on the surface of the adjusting cylinder 219, respectively.

[0036] An isolation ring 211 is fixedly connected in the first circular groove on the surface of the charcoal box 207. A first sealing ring 212 is fixedly connected inside the isolation ring 211. The adjusting cylinder 219 is slidably connected to several first sealing rings 212.

[0037] Each telescopic section of the multi-section telescopic rod 216 has a protective spherical shell 221 fixedly connected near the top end. A magnetic ring 220 is fixedly connected inside the protective spherical shell 221. There is a repulsive force between any adjacent magnetic rings 220 on the same surface of the multi-section telescopic rod 216.

[0038] A second water permeable groove 208 is provided on the surface of the charcoal column 210. A water guide plate 209 is provided inside the second water permeable groove 208. The water guide plate 209 is fixedly connected to the charcoal box 207 and abuts against the charcoal column 210.

[0039] In this embodiment of the invention, when no water is introduced into the filter cartridge housing 101, the multi-section telescopic rod 216 maintains its maximum elongation under the repulsive force of the magnetic rings 220 on its surface. At this time, the adjusting cylinder 219 is located below the uppermost carbon box 207. After water is injected into the filter cartridge housing 101, the water first passes through the primary carbon rod filter element and enters the interior of the isolation tube 222. It then enters the interior of the flexible hose 217 through the third circular groove on the surface of the isolation plate 218, and flows from the surface of the adjusting cylinder 219 to the carbon column 210. After being filtered by the carbon column 210, the water flows into the carbon column 210 and the carbon box. Between 207, under the constraint of the water guide plate 209, the water in the carbon box 207 flows out from the second water permeable groove 208. This process will cause the carbon box 207 to rotate, so as to improve the filtration efficiency of the carbon column 210 and reduce the probability of clogging of the carbon column 210. When the water pressure inside the filter cartridge housing 101 increases, the multi-section telescopic rod 216 will overcome the repulsive force between the two adjacent magnetic rings 220 and shorten under the action of water pressure, so as to adjust the downward movement of the cylinder 219. The spherical setting of the protective spherical shell 221 is to prevent the magnetic rings 220 from squeezing the hose 217 when the multi-section telescopic rod 216 deforms.

[0040] like Figures 1 to 10 As shown, a connecting pipe 214 is fixedly connected in the fifth circular groove starting from the surface of the top cover 201. An isolation inner cover 213 is provided at the bottom of the connecting pipe 214. The connecting pipe 214 is fixedly connected in the sixth circular groove opened on the surface of the isolation inner cover 213. A sealing sheet 215 is fixedly connected to the bottom surface of the isolation inner cover 213. An annular groove corresponding to the isolation ring 211 is opened on the bottom surface of the sealing sheet 215.

[0041] In this embodiment of the invention, the bottom cover 102 is provided to facilitate the replacement of the primary carbon rod filter element on the surface of the isolation tube 222, and the top cover 201 is provided to facilitate the replacement of the carbon box 207 and the high-efficiency carbon rod filter element. During the downward rotation of the top cover 201 on the surface of the filter element shell 101, the inner cover 213 of the isolation tube is tightly fitted with the upper surface of the first isolation cylinder 203, so that the water passing through the high-efficiency carbon rod filter element can be discharged from the interior of the top cover 201 through the connecting pipe 214. During the downward rotation of the top cover 201 on the surface of the filter element shell 101, the sealing plate 215 is tightly fitted with the upper surface of the placement cylinder 205, and the isolation ring 211 is fitted into the annular groove on the bottom surface of the sealing plate 215 to prevent water from being discharged from the top of the placement cylinder 205. This facilitates the water discharged from the regulating cylinder 219 to be filtered by the carbon column 210 and then discharged from the first water permeable groove 206, thereby facilitating the filtration of the high-efficiency carbon rod filter element.

[0042] It should be noted that the adjusting cylinder 219 does not come into contact with the carbon column 210 to avoid wear on the carbon column 210 caused by the movement of the adjusting cylinder 219. During the rotation of the charcoal box 207, the first water permeable groove 206 and the second water permeable groove 208 are always connected to ensure the flow of water; Both the high-efficiency carbon rod filter element and the pre-filter carbon rod filter element are hollow cylindrical in shape, which makes it easy to place them inside the filter element shell 101. The filtration and adsorption effect of the high-efficiency carbon rod filter element is better than that of the carbon rod 210, and the filtration and adsorption effect of the carbon rod 210 is better than that of the pre-filter carbon rod filter element, so that each filter element in operation can maintain a good filtration effect. The surface of the top cover 201 is provided with a water inlet to facilitate the filling of water into the filter element housing 101; The surface of the isolation ring 211 is smooth, which helps to reduce the rotational resistance of the carbon column 210. When the first sealing ring 212 contacts the regulating cylinder 219, it plays a sealing role to prevent downward flow. The inner wall of the placement cylinder 205 is made of an elastic sealing material. When the charcoal box 207 is placed inside the placement cylinder 205, the inner wall of the placement cylinder 205 will undergo elastic deformation to maintain the sealing contact between the inner wall of the placement cylinder 205 and the surface of the charcoal box 207, so that water can be discharged from the second permeable groove 208 and then leave the interior of the placement cylinder 205 through the first permeable groove 206. The bottom surface of the inner isolation cover 213 is made of sealing material, so that the inner isolation cover 213 and the first isolation cylinder 203 are tightly fitted together and the sealing contact between the inner isolation cover 213 and the first isolation cylinder 203 is maintained.

[0043] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
