Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to an activated carbon filter which can be quickly replaced. Background Technique

[0002] At present, the purification treatment of water generally adopts mechanical filtration methods or chemical and biological treatment methods; usually, mechanical filtration methods are applicable to colloidal suspended matters or granular impurities; but for some harmful substances in water, that is, wastewater or sewage; for water quality treatment, chemical and biological treatment methods are usually adopted, which can form a water purification effect after treating the harmful substances in the wastewater or sewage. Activated carbon is an adsorbent that can adsorb harmful substances in water. At the same time, due to its microporous filtration effect, it can also have a certain mechanical filtration effect, removing tiny colloidal suspended matters and granular impurities, and is used as a commonly used water purification treatment material; however, for traditional filters using activated carbon for water purification, after a long time, due to the adsorbed impurities being retained inside the activated carbon, the adsorption effect of the activated carbon is greatly reduced, and the replacement of the activated carbon filter element is difficult, affecting work efficiency.

[0022] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0023] Combined with Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 , a replaceable activated carbon filter quickly, including an outer shell 1, an upper cover 2 is arranged at the upper end of the outer shell 1, a first elastic member 3 is arranged inside the upper cover 2, a filter element 4 is arranged inside the outer shell 1, a lower cover 5 is arranged at the lower end of the outer shell 1, a second elastic member 6 is arranged inside the outer shell 1, an L-shaped groove 24 is penetrated and opened inside the upper cover 2, a triangular groove 11 is opened on the upper surface of the outer shell 1, the first elastic member 3 includes a telescopic rod 31, one end of the telescopic rod 31 is fixedly connected to the surface of the L-shaped groove 24, the other end of the telescopic rod 31 is fixedly installed with a triangular insertion block 32, the triangular insertion block 32 matches the triangular groove 11, a dial block 33 is fixedly installed on one side of the triangular insertion block 32, a first spring 34 is fixedly installed at one end of the triangular insertion block 32 close to the telescopic rod 31, the end of the first spring 34 away from the triangular insertion block 32 is fixedly connected to the surface of the L-shaped groove 24, and the first spring 34 is located outside the telescopic rod 31. During installation, first use hand to dial the dial block 33 to make the triangular insertion block 32 compress the first spring 34, so that the triangular insertion block 32 retracts into the L-shaped groove 24. Then align the upper cover 2 with the outer shell 1 and turn it to complete the threaded connection. Subsequently, release the dialing of the dial block 33, the first spring 34 resets and pushes the triangular insertion block 32 into the triangular groove 11. At this time, the upper cover 2 and the outer shell 1 cannot rotate, and thus will not loosen, realizing quick fixation. During disassembly, except that the turning direction is opposite, the remaining operations are the same, realizing quick disassembly.

[0024] Combined with Figure 2 、Figures 6 - 7 The filter element 4 includes an outer ring 41. A clamping groove 42 is formed on the surface of the outer ring 41. A groove 12 is formed through the interior of the housing 1. The second elastic member 6 includes a second spring 61 fixedly connected to the surface of the groove 12. One end of the second spring 61 is fixedly provided with a clamping block 62. The clamping block 62 is matched with both the clamping groove 42 and the groove 12. A pull rod 63 is fixedly installed at one end of the clamping block 62 close to the second spring 61. The end of the pull rod 63 away from the clamping block 62 penetrates through the housing 1 and is fixedly provided with a pull ring 64. When installing the filter element 4, the outer ring 41 will push the clamping block 62 to compress the second spring 61, causing the clamping block 62 to retract into the groove 12 until the clamping groove 42 corresponds to the clamping block 62. The second spring 61 resets and pushes the clamping block 62 to fit and contact with the clamping groove 42, completing rapid fixation. When it is necessary to disassemble, clean or replace the filter element 4, by pulling the pull ring 64 to drive the pull rod 63 and the clamping block 62 to compress the second spring 61, the clamping block 62 is withdrawn from the clamping groove 42, and the filter element 4 can be taken out to achieve rapid disassembly.

[0025] Combined with Figure 2 Inside the outer ring 41, multiple non-woven fabric layers 43 are fixedly installed, and an activated carbon layer 44 is fixedly installed between two adjacent non-woven fabric layers 43.

[0026] Combined with Figure 4 The lower cover 5 includes a fixing plate 51. Multiple third springs 53 are fixedly installed at the upper end of the fixing plate 51. A ring plate 52 is fixedly installed at the upper end of the third springs 53. During the process of the filter element 4 being engaged with the second elastic member 6, the ring plate 52 will be pushed to compress the third springs 53. When the second elastic member 6 stops engaging with the filter element 4, the third springs 53 reset and push the ring plate 52 to eject the filter element 4 out of the housing 1 by a certain distance, making it more convenient for personnel to take out the filter element 4 for subsequent operations.

[0027] Combined with Figure 3 Multiple through holes 22 are formed through the upper cover 2 and the fixing plate 51. A tapered hole 23 is formed at one end of the through hole 22. Through the arrangement of the multiple through holes 22 and the tapered holes 23, the flow rate of the incoming water is slowed down, thereby further improving the filtering performance of the filter element 4.

[0028] Combined with Figures 3 - 4 Sealing connectors 21 are fixedly installed at the opposite ends of the upper cover 2 and the fixing plate 51. Through the arrangement of the sealing connectors 21, the sealing performance of the connection with the pipeline is enhanced, preventing waste of water resources.

[0029] The specific working process and principle of the utility model are as follows: when installing, the filter element 4 is inserted into the housing 1, and the outer ring 41 pushes the block 62 to squeeze the spring 2 61, so that the block 62 retreats into the groove 12 until the groove 42 corresponds to the block 62, and the spring 2 61 resets and pushes the block 62 to fit into the groove 42 to complete the quick fixation. When the filter element 4 needs to be disassembled, cleaned or replaced, the pull ring 64 drives the pull rod 63 and the block 62 to squeeze the spring 2 61, so that the block 62 withdraws from the groove 42. When the elastic member 2 6 stops engaging with the filter element 4, the spring 3 53 resets and pushes the ring plate 52 to filter the filter. The filter element 4 is pushed out of the housing 1 for a distance, which makes it more convenient for personnel to take out the filter element 4 for subsequent operations, thereby realizing quick disassembly. Then, the shifting block 33 is manually moved to make the triangular plug 32 squeeze the spring 1 34, thereby making the triangular plug 32 retreat to the inside of the L groove 24. Then, the upper cover 2 is aligned with the housing 1 and screwed to complete the threaded connection. Then, the shifting of the shifting block 33 is released, and the spring 1 34 is reset and pushes the triangular plug 32 into the triangular groove 11. At this time, the upper cover 2 and the housing 1 cannot rotate, and thus no loosening occurs, thereby realizing quick fixation. During disassembly, except for the opposite screwing direction, the other operations are the same, thereby realizing quick disassembly.
