Description

Technical Field

[0001] This invention relates to the field of filter can technology, specifically to an activated carbon filter can. Background Technology

[0002] Commonly used filter canisters have a layer of activated carbon inside, through which gas passes. After a period of use, all the activated carbon needs to be removed and replaced with new activated carbon. However, replacing the activated carbon in this type of filter canister is inconvenient, time-consuming, and frequent replacements can significantly reduce the efficiency of the canister.

[0003] To this end, Chinese Patent Publication No. CN207042089U discloses "An Activated Carbon Filter Tank," the main structure of which includes a tank body, with an inlet pipe and an outlet pipe at each end of the tank body, and several mounting holes on both sides of the tank body, which are staggered. A filter element device is detachably sealed at each mounting hole on the tank body. The radial length of the filter element device is less than the width of the tank body. The filter element device includes a mounting plate that mates with the outer surface of the tank body, and a fixing frame is provided on the mounting plate. A sealing mesh is detachably provided on the fixing frame. The activated carbon filter canister contains several mounting holes on both sides of the canister, which are staggered. Filter cartridges are detachably sealed at the mounting holes on the canister. The radial length of the filter cartridge is less than the width of the canister. The filter cartridge includes a mounting plate that mates with the outer surface of the canister. A fixing frame is provided on the mounting plate, and a sealing mesh is detachably provided on the fixing frame. Activated carbon is placed inside the sealing mesh on the fixing frame. This allows the exhaust gas to bypass the individual filter cartridges within the canister and still be filtered cleanly at a high flow rate, thus improving filtration efficiency.

[0004] In actual use, the activated carbon filter canister has an S-shaped flow gap between each pair of filter elements, which leads to a significant decrease in the filtration effect. At the same time, the sealing mesh filters the medium for a long time, which makes it prone to clogging after a period of operation, resulting in low filtration efficiency and a significant reduction in its effective usage time per use.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1 , Figure 2 and Figure 3 An activated carbon filter canister includes a vertical media flow shell 1, a longitudinal media flow cavity 5 disposed inside the vertical media flow shell 1 with an open bottom, a docking channel 6 disposed on the top circumferential surface of the vertical media flow shell 1 and communicating with the longitudinal media flow cavity 5, a drive motor 3 fixedly mounted on the top of the vertical media flow shell 1 via a motor fixing shell 2, a screw 8 installed inside the longitudinal media flow cavity 5 and rotating with the rotor 4 of the drive motor 3, a first component fixing plate 7 integrally disposed at the bottom of the vertical media flow shell 1, and a channel 6 disposed on the circumferential surface of the vertical media flow shell 1 and communicating with the longitudinal media flow cavity 5. The filter hole 9 of the moving cavity 5 connects the docking channel 6 with the channel used to transport the medium. When the medium flows, the drive motor 3 is turned on, and the rotor drives the screw 8 to move. Impurities in the medium are blocked by the filter hole 9 at the inner circumferential surface of the vertical medium flow shell 1. At the same time, the medium flows to the outer space through the filter hole 9. After the drive motor 3 is started, the rotation of the screw 8 causes the material around it to move downward. The impurities blocked at the inner circumferential surface of the vertical medium flow shell 1 will be concentrated and discharged downward under the action of the rotating screw 8, thereby ensuring the smooth flow of air in the filter hole 9.

[0028] To achieve the activated carbon adsorption function of the medium, please refer to [link / reference needed]. Figure 1, Figure 2 , Figure 4 and Figure 5 An activated carbon storage mechanism 10 needs to be set up, which includes a longitudinal hollow shell 101 fixedly installed in the vertical medium flow shell 1, a lower medium flow chamber 103 located inside the longitudinal hollow shell 101 and capable of accommodating medium from the direction of the filter holes 9, a middle activated carbon storage chamber 104 located inside the longitudinal hollow shell 101 and capable of activating carbon adsorption of medium from the direction of the lower medium flow chamber 103, and an upper medium flow chamber 105 located inside the longitudinal hollow shell 101 and capable of accommodating medium from the direction of the middle activated carbon storage chamber 104. The annular closing plate 109 is pulled upwards, and then activated carbon particles are placed inside. Inside the central activated carbon storage chamber 104, to prevent leakage of activated carbon through the medium flow hole 1010, the diameter of the medium flow hole 1010 needs to be smaller than the size of the activated carbon stored in the central activated carbon storage chamber 104, so that the activated carbon is spread evenly inside the central activated carbon storage chamber 104. Then, the annular closing plate 109 is closed downwards. When the medium flows into the lower medium flow chamber 103 through the filter hole 9, due to the pressure of the medium, the medium will flow upward through the gaps between the activated carbon. Odors in the medium will be adsorbed by the activated carbon. The adsorbed medium will be discharged outwards through the medium discharge channel 107, thereby realizing the activated carbon adsorption function of the medium.

[0029] For details regarding the specific structure of the activated carbon storage mechanism 10, please refer to [link / reference needed]. Figure 4 and Figure 5The system includes a longitudinal hollow outer shell 101 with a support leg 102 fixedly mounted at the bottom. The longitudinal hollow outer shell 101 and the vertical media flow shell 1 are sealed at their mounting contact surfaces. The longitudinal hollow outer shell 101 has a component fixing port 106 at its center, connecting its upper and lower end faces. A portion of the structure of the vertical media flow shell 1 is fixedly mounted inside the component fixing port 106. The interior of the longitudinal hollow outer shell 101 has a lower media flow cavity 103 with an open inner side. The inner opening of the lower media flow cavity 103 communicates with the filter hole 9. The longitudinal hollow outer shell 101 has a middle activated carbon storage cavity 104 with an open outer side located directly above the lower media flow cavity 103. The longitudinal hollow outer shell 101 has an upper media flow cavity 105 with an open inner side located directly above the middle activated carbon storage cavity 104. The interior of the longitudinal hollow outer shell 101 has a connection to the lower... The longitudinal hollow shell 101 has a medium flow chamber 103 and a middle activated carbon storage chamber 104, and multiple medium flow holes 1010 located below it. The interior of the longitudinal hollow shell 101 is provided with multiple medium flow holes 1010 that connect the middle activated carbon storage chamber 104 and the upper medium flow chamber 105, and located above it. The upper end face of the longitudinal hollow shell 101 is provided with a medium discharge channel 107 that connects the external space and the upper medium flow chamber 105. The longitudinal hollow shell 101 has a downwardly recessed annular insertion groove 108 located on the outer periphery of the bottom end of the middle activated carbon storage chamber 104. An annular closing plate 109 that can be inserted into the annular insertion groove 108 is fitted on the outer circumference of the longitudinal hollow shell 101. The height of the annular closing plate 109 is greater than the sum of the depth of the annular insertion groove 108 and the height of the middle activated carbon storage chamber 104. The structural radius of the inner ring of the annular closing plate 109 is the same as the structural radius of the outer ring of the longitudinal hollow shell 101.

[0030] To achieve a squeeze-type discharge effect for the filtered impurities, please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7A flexible discharge mechanism 11 is required, which includes a vertical cylinder 111 fixedly installed at the bottom of the vertical medium flow housing 1 and capable of accommodating material from the longitudinal medium flow cavity 5; a lower limit movable plate 119 abutting against the bottom of the vertical cylinder 111 and capable of providing an upward limiting effect on the concentrated material; and a helical spring 118 that provides elastic damping effect to the mutual separation of the vertical cylinder 111 and the lower limit movable plate 119. The concentrated debris continuously accumulates inside the debris discharge cavity 114, and under the continuous debris conveying action of the screw 8, it will... The debris is compressed and piled up against the upper surface of the lower limit movable plate 119. When the force of this compression and accumulation is greater than the elastic strength of the coil spring 118, the lower limit movable plate 119 will move downward. At this time, the debris is still in the form of accumulation and compression, and the medium cannot leak along the gaps between the debris. When it is observed that the exposed debris has reached a certain level, the accumulated debris can be pushed laterally to discharge the debris. The elasticity of the coil spring 118 will promptly reset the lower limit movable plate 119 upward, thereby achieving the effect of compression and discharge of the filtered debris.

[0031] For details regarding the specific structure of the elastic feeding mechanism 11, please refer to [link / reference]. Figure 6 and Figure 7 The system includes a vertical cylindrical body 111 and a lower limit movable plate 119. The top of the vertical cylindrical body 111 is provided with a second component fixing plate 112, which is integrally structured with and fixedly installed at the bottom of a first component fixing plate 7. The bottom of the vertical cylindrical body 111 is provided with an upper limit movable plate 113, which is integrally structured with it. A debris discharge chamber 114 communicating with its upper and lower end faces is provided at the center of the vertical cylindrical body 111. The upper limit movable plate 113 has multiple rod through holes 115 arranged in a ring array inside. The lower limit movable plate 119... The upper end face is fixedly installed with a plurality of longitudinal limiting rods 116 through rod holes 115. Each longitudinal limiting rod 116 has a top limiting plate 117 installed at its top. A helical spring 118 is sleeved on the outer periphery of the rod body above the upper limit movable plate 113 of the longitudinal limiting rod 116. The bottom end of the helical spring 118 abuts against the upper surface of the upper limit movable plate 113 and the top end abuts against the bottom surface of the top limiting plate 117. The initial length of the helical spring 118 is greater than the height of the longitudinal limiting rod 116.

[0032] In use, the docking channel 6 is connected to the channel used for conveying the medium. When the medium flows, the drive motor 3 is turned on. Impurities in the medium are blocked by the filter holes 9 at the inner circumferential surface of the vertical medium flow housing 1. At the same time, the medium flows to the outer space through the filter holes 9. The impurities blocked at the inner circumferential surface of the vertical medium flow housing 1 are concentrated and discharged downwards by the rotating screw 8. When the medium flows into the lower medium flow chamber 103 through the filter holes 9, due to the pressure of the medium, it will flow upwards through the gaps between the activated carbon. The odor will be adsorbed by activated carbon, and the adsorbed medium will be discharged outward through the medium discharge channel 107. Meanwhile, the concentrated debris will continuously accumulate inside the debris discharge chamber 114, causing the debris to press against the upper surface of the lower limit movable plate 119 in the form of compression and accumulation. When the force of this compression and accumulation is greater than the elastic strength of the helical spring 118, the lower limit movable plate 119 will move downward. When it is observed that the exposed debris has reached a certain level, the accumulated debris can be pushed laterally to discharge the debris. The elasticity of the helical spring 118 will promptly reset the lower limit movable plate 119 upward.
