Description

Technical Field

[0001] This invention relates to a liquid filter, and more particularly to a liquid filter utilizing activated carbon, applicable to the field of filtration equipment technology. Background Technology

[0002] Liquid filters are widely used in many industries. They are mainly used to achieve solid-liquid separation by using porous filter media to trap solid particles in a mixture of liquid and solid particles.

[0003] Activated carbon is widely used in the field of liquid filtration due to its excellent adsorption properties, and many liquid filtration machines choose to use activated carbon to filter liquids.

[0004] During the use of liquid filters, unstable liquid flow rates are inevitable. When the liquid flow rate is too low, in existing liquid filters, the liquid can only contact a portion of the activated carbon, resulting in uneven utilization of the activated carbon. This not only affects the filtration effect but also reduces the utilization rate of the activated carbon. Therefore, we propose a liquid filter that utilizes activated carbon. Summary of the Invention

[0005] The technical problem to be solved by the present invention in view of the above-mentioned prior art is that when the liquid flow rate is too low, the liquid can only come into contact with a portion of the activated carbon in the liquid filter of the prior art, which will cause uneven utilization of activated carbon, which will not only affect the filtration effect, but also reduce the utilization rate of activated carbon.

[0006] To address the aforementioned problems, this invention provides a liquid filter utilizing activated carbon, comprising a cylindrical filter chamber and a flow-adjustable filtration mechanism. The filter chamber is connected to an inlet pipe and an outlet pipe at its upper and lower ends, respectively. A flow meter is installed on the inlet pipe. The flow-adjustable filtration mechanism includes a carbon core filter assembly disposed inside the filter chamber, an adjustment drive assembly, and an adjustment controller fixedly installed at the top of the filter chamber. The carbon core filter assembly includes a wear-resistant outer ring body that matches the filter chamber and is movably and sealingly connected to the inner wall of the filter chamber. A matching inner sealing ring body is fixedly connected to the inner side of the wear-resistant outer ring body. Two matching liquid-permeable carbon-blocking meshes are fixedly connected to the inner side of the inner sealing ring body. A through hole is provided in the center of each liquid-permeable carbon-blocking mesh. It also includes an inner sealing column that matches the through holes. The inner sealing column passes through the through holes of the two liquid-permeable carbon-blocking nets and is fixedly connected to the two liquid-permeable carbon-blocking nets. An annular cavity is formed between the two liquid-permeable carbon-blocking nets, the inner sealing interlocking body, and the inner sealing column. The annular cavity is filled with an activated carbon filter body composed of activated carbon. The bottom end of the water inlet pipe faces the activated carbon filter body. The adjustment drive assembly includes a drive motor fixedly installed on the inner wall of the top of the filter chamber. The output end of the drive motor is fixedly connected to a linkage shaft. The linkage shaft is connected to the carbon core filter assembly for transmission. The adaptive controller is equipped with a monitoring and analysis module and a rotation adjustment module. The flow meter is connected to the monitoring and analysis module for signal connection. The monitoring and analysis module is connected to the rotation adjustment module for signal connection. The rotation adjustment module is connected to the drive motor for signal connection.

[0007] In the liquid filter using activated carbon described above, when the liquid flow rate is too low, the adaptive controller will control the drive motor in the adjustment drive assembly to rotate the carbon core filter assembly, causing the part of the activated carbon filter body in direct contact with the liquid to change continuously. This allows the liquid to have uniform and sufficient contact with the activated carbon, avoiding uneven utilization of activated carbon due to low liquid flow rate. This not only improves the filtration effect but also increases the utilization rate of activated carbon.

[0008] As a further improvement of this application, the filter chamber consists of an upper cylinder and a lower cylinder that matches the upper cylinder. The bottom end of the upper cylinder and the top end of the lower cylinder are both open. The upper cylinder and the lower cylinder are fixedly connected. The fixed connections between the upper cylinder and the lower cylinder, the inner sealing ring and the liquid-permeable carbon-blocking mesh, and the liquid-permeable carbon-blocking mesh and the inner sealing column are all detachable fixed connections, which facilitates the maintenance of the carbon core filter assembly.

[0009] As a further improvement of this application, the linkage shaft is connected by a linkage square rod, a linkage square sleeve, and a carbon core filter assembly. A square linkage square rod is fixedly connected to the bottom end of the linkage shaft, and a linkage square sleeve matching the linkage square rod is fixedly connected to the top end of the inner sealing column. The linkage square sleeve is set in a U-shape, and the linkage square rod and the linkage square sleeve are movably inserted into each other, which makes it easy to replace the activated carbon filter.

[0010] As a further improvement of this application, multiple support blocks are fixedly installed on the inner wall of the filter chamber. The support blocks are located below the carbon core filter assembly. Universal ball bearings are fixedly installed on the top of the support blocks. The universal ball bearings abut against the bottom of the carbon core filter assembly. The support blocks and universal ball bearings can provide support for the carbon core filter assembly. Furthermore, the universal ball bearings can reduce wear during the rotation of the carbon core filter assembly.

[0011] As a further improvement of this application, the wear-resistant outer ring is made of wear-resistant material, and the connection between the wear-resistant outer ring and the inner sealing ring is a detachable fixed connection, which can reduce the maintenance cost of the carbon core filter assembly. The outer cover of the drive motor is equipped with a motor waterproof cover, and the linkage shaft passes through the motor waterproof cover and is movably and sealed to it. The motor waterproof cover can protect the drive motor and extend the service life of the drive motor.

[0012] As another improvement of this application, a wear detection and contact enhancement component is also provided in the filter chamber, and a wear detection module is also provided in the adaptive controller. An indicator light is fixedly installed on the outer wall of the filter chamber, and a solenoid valve is provided on the drain pipe. The wear detection and contact enhancement component includes a lifting cylinder fixedly installed on the inner wall at the bottom of the filter chamber. A sealing plate matching the liquid-permeable carbon-blocking mesh is fixedly connected to the output end of the lifting cylinder, and a liquid level sensor is fixedly installed at the bottom end of the sealing plate.

[0013] As a further improvement to this application, the sealing plate is located directly below the two liquid-permeable carbon-blocking screens. The monitoring and analysis module is signal-connected to the wear detection module, and the wear detection module is signal-connected to the drive cylinder, liquid level sensor, solenoid valve, and indicator light. This allows the wear detection and contact enhancement component to automatically detect the sealing performance at the connection between the wear-resistant outer ring and the inner wall of the filter chamber under the control of the adaptive controller.

[0014] As a further improvement to this application, the outer cover of the lifting cylinder is provided with a cylinder waterproof cover. The output end of the lifting cylinder passes through the cylinder waterproof cover and is movably and sealed to it. The cylinder waterproof cover can protect the lifting cylinder and extend its service life.

[0015] In summary, this application, through the setting of the flow-adjustable filtration mechanism, features a unique structural design for the carbon core filter assembly. The adjustment controller can monitor and analyze the liquid flow rate. When the liquid flow rate is too low, the adjustment controller will control the drive motor in the adjustment drive assembly to rotate the carbon core filter assembly, causing the part of the activated carbon filter body in direct contact with the liquid to continuously change. This ensures that the liquid can have uniform and sufficient contact with the activated carbon, avoiding uneven utilization of activated carbon due to low liquid flow rate. This not only improves the filtration effect but also increases the utilization rate of activated carbon, greatly enhancing the practicality, reliability, and intelligence of the filter. Furthermore, the carbon core filter assembly is easy to maintain, and the activated carbon filter body is easy to replace, further improving the filtration efficiency. The practicality of the filter: Through the combined setup of the adaptive controller and the wear detection and contact enhancement component, the wear detection and contact enhancement component can automatically detect the sealing performance of the connection between the wear-resistant outer ring and the inner wall of the filter chamber under the control of the adaptive controller. If there is a problem with the sealing performance of the connection, it indicates that the wear of the wear-resistant outer ring may be serious and requires maintenance or replacement. The adaptive controller will illuminate an indicator light to remind relevant technicians to perform the corresponding maintenance work in a timely manner, thereby ensuring the filtration effect of the carbon core filter assembly and further improving the practicality and reliability of the filter. Moreover, the detection also ensures that the liquid can contact the activated carbon more evenly and fully, thereby further improving the filtration effect and the utilization rate of activated carbon.

[0026] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0027] First implementation method:

[0028] Figure 1-6This invention discloses a liquid filter using activated carbon, comprising a cylindrical filter chamber 101 and a flow-adjustable filtration mechanism. The filter chamber 101 is connected to an inlet pipe 102 and an outlet pipe 104 at its upper and lower ends, respectively. A flow meter 103 is installed on the inlet pipe 102. The flow-adjustable filtration mechanism includes a carbon core filter assembly disposed inside the filter chamber 101, an adjustment drive assembly, and an adjustment controller 004 fixedly installed at the top of the filter chamber 101. The carbon core filter assembly includes a wear-resistant outer ring 201 that matches the filter chamber 101 and is movably and sealingly connected to the inner wall of the filter chamber 101. A matching inner sealing ring 202 is fixedly connected to the inner side of the wear-resistant outer ring 201. Two matching liquid-permeable carbon-blocking meshes 203 are fixedly connected to the inner side of the inner sealing ring 202. Each liquid-permeable carbon-blocking mesh 203 has a through hole in its center. The carbon core filter assembly also includes components matching the through holes. The inner sealing column 204 is provided, which penetrates through the through holes on the two liquid-permeable carbon-blocking nets 203 and is fixedly connected to the two liquid-permeable carbon-blocking nets 203. An annular cavity is formed between the two liquid-permeable carbon-blocking nets 203, the inner sealing ring body 202, and the inner sealing column 204. The annular cavity is filled with an activated carbon filter body 205 composed of activated carbon. The bottom end of the water inlet pipe 102 faces the activated carbon filter body 205. The adjustment drive assembly includes a drive motor 301 fixedly installed on the inner wall of the top of the filter chamber 101. The output end of the drive motor 301 is fixedly connected to a linkage shaft 302. The linkage shaft 302 is connected to the carbon core filter assembly. The adaptive controller 004 is equipped with a monitoring and analysis module and a rotation adjustment module. The flow meter 103 is connected to the monitoring and analysis module, the monitoring and analysis module is connected to the rotation adjustment module, and the rotation adjustment module is connected to the drive motor 301.

[0029] The inlet pipe 102 and outlet pipe 104 are connected to corresponding pipes. When filtering liquid, the liquid can enter the filter chamber 101 through the inlet pipe 102. The carbon core filter assembly can adsorb and filter the liquid. The treated liquid can be discharged through the outlet pipe 104. The flow meter 103 can monitor the liquid flow rate, and the monitored flow rate data will be transmitted to the monitoring and analysis module in real time. Those skilled in the art can reasonably set a flow threshold according to the actual situation. When the liquid flow rate is lower than the flow threshold, that is, when the liquid flow rate is too low, causing the liquid to not be able to fully and comprehensively contact the activated carbon filter 205, the monitoring and analysis module will send a command to the rotation adjustment module, causing the rotation adjustment module to start the drive motor 301 to drive the carbon core filter assembly. The activated carbon filter element 205 rotates at a certain speed, causing the contact area between the activated carbon filter element 205 and the liquid to continuously change. Therefore, through the setting of the flow-adjustable filtration mechanism, the carbon core filter assembly has a unique structural design. The adjustment controller 004 can monitor and analyze the liquid flow rate. When the liquid flow rate is too low, the adjustment controller 004 will control the drive motor 301 in the adjustment drive assembly to drive the carbon core filter assembly to rotate, causing the contact area between the activated carbon filter element 205 and the liquid to continuously change. This allows the liquid to have uniform and sufficient contact with the activated carbon, avoiding uneven utilization of activated carbon due to low liquid flow rate. This not only improves the filtration effect but also increases the utilization rate of activated carbon, greatly improving the practicality, reliability, and intelligence of the filter.

[0030] Please see Figure 1-2 The filter chamber 101 consists of an upper cylinder 011 and a lower cylinder 012 that matches the upper cylinder 011. The bottom end of the upper cylinder 011 and the top end of the lower cylinder 012 are both open. The upper cylinder 011 and the lower cylinder 012 are fixedly connected. The fixed connections between the upper cylinder 011 and the lower cylinder 012, the inner sealing ring body 202 and the liquid-permeable carbon-blocking mesh 203, and the liquid-permeable carbon-blocking mesh 203 and the inner sealing column body 204 are all detachable fixed connections, which facilitates the maintenance of the carbon core filter assembly.

[0031] Please see Figure 2 and Figure 4-5 The linkage shaft 302 is connected to the carbon core filter assembly via the linkage square rod 303, the linkage square sleeve 304, and the carbon core filter assembly. The bottom end of the linkage shaft 302 is fixedly connected to the square linkage rod 303, and the top end of the inner sealing column 204 is fixedly connected to the linkage square sleeve 304 that matches the linkage square rod 303. The linkage square sleeve 304 is set in a U-shape. The linkage square rod 303 and the linkage square sleeve 304 are movably inserted into each other, so that the drive motor 301 can smoothly drive the carbon core filter assembly to rotate through the linkage shaft 302. The linkage shaft 302 and the carbon core filter assembly are easy to separate, which facilitates the replacement of the activated carbon filter 205.

[0032] Please see Figure 2-3Multiple support blocks 105 are fixedly installed on the inner wall of the filter chamber 101. The support blocks 105 are located below the carbon core filter assembly. Universal ball bearings 106 are fixedly installed on the top of the support blocks 105. The universal ball bearings 106 abut against the bottom of the carbon core filter assembly. The support blocks 105 and universal ball bearings 106 can provide support for the carbon core filter assembly. Furthermore, the universal ball bearings 106 can reduce wear during the rotation of the carbon core filter assembly.

[0033] Please see Figure 4-5 The wear-resistant outer ring 201 is made of wear-resistant material. The connection between the wear-resistant outer ring 201 and the inner sealing ring 202 is a detachable fixed connection. When the drive motor 301 drives the carbon core filter assembly to rotate, the wear-resistant outer ring 201 will inevitably wear. When the wear-resistant outer ring 201 is severely worn, it can be replaced separately without replacing the entire carbon core filter assembly, which can reduce the maintenance cost of the carbon core filter assembly. The drive motor 301 is covered with a motor waterproof cover 305. The linkage shaft 302 passes through the motor waterproof cover 305 and is movably and sealed to it. The motor waterproof cover 305 can protect the drive motor 301 and extend the service life of the drive motor 301.

[0034] Second implementation method:

[0035] Figure 7-8This invention discloses a liquid filter utilizing activated carbon. Unlike the first embodiment, the filter chamber 101 is further equipped with a wear detection and contact enhancement assembly, and the adaptation controller 004 includes a wear detection module. An indicator light is fixedly installed on the outer wall of the filter chamber 101, and a solenoid valve 107 is installed on the drain pipe 104. The wear detection and contact enhancement assembly includes a lifting cylinder 501 fixedly installed on the inner wall at the bottom of the filter chamber 101. A sealing plate 502 matching the liquid-permeable carbon-blocking mesh 203 is fixedly connected to the output end of the lifting cylinder 501. A liquid level sensor 503 is fixedly installed at the bottom end of the sealing plate 502, which is located directly below the two liquid-permeable carbon-blocking meshes 203. The monitoring and analysis module is signal-connected to the wear detection module, and the wear detection module is connected to the lifting cylinder 501 and the liquid... The level sensor 503, solenoid valve 107, and indicator light are all connected for signal transmission. When the liquid flow rate is lower than the flow threshold, the monitoring and analysis module will send a signal to the wear detection module. Upon receiving the signal, the wear detection module will activate the lifting cylinder 501, causing it to push the sealing plate 502 upwards until it abuts against the bottom of the carbon core filter assembly. This causes the sealing plate 502 to block and seal the liquid-permeable carbon-blocking mesh 203 located below the activated carbon filter 205, preventing the downward flow of liquid. Then, the wear detection module will close the solenoid valve 107 and open the level sensor 503. The level sensor 503 can monitor the liquid level below the carbon core filter assembly, and the liquid level data monitored by the level sensor 503 will be transmitted to the wear detection module in real time. After a certain period of time... If the liquid level below the carbon core filter assembly does not change significantly, it indicates that the seal at the connection between the wear-resistant outer ring 201 and the inner wall of the filter chamber 101 is still reliable, and the wear-resistant outer ring 201 is in good condition and requires no maintenance or replacement. The wear detection module will control the lifting cylinder 501 to move the sealing plate 502 downward to reset, and close the liquid level sensor 503 and open the solenoid valve 107. Conversely, if the liquid level below the carbon core filter assembly rises, it indicates that there is liquid leakage downward, and the seal at the connection between the wear-resistant outer ring 201 and the inner wall of the filter chamber 101 may have a problem. The wear of the wear-resistant outer ring 201 may be quite severe, requiring maintenance or replacement. In this case, the wear detection module will not only control the lifting cylinder 501 to move the sealing plate 502 downward to reset, but also... When the liquid level sensor 503 is turned off, an indicator light will illuminate to alert relevant technicians. In this situation, the wear detection module will not open the solenoid valve 107 to prevent unfiltered liquid from being discharged. Furthermore, during the detection process, because the downward flow of liquid is blocked, liquid accumulates above the carbon core filter assembly, allowing for sufficient contact between the liquid and the activated carbon. Therefore, through the combined configuration of the adaptability controller 004 and the wear detection and contact enhancement component, the wear detection and contact enhancement component can automatically detect the sealing performance at the connection between the wear-resistant outer ring 201 and the inner wall of the filter chamber 101 under the control of the adaptability controller 004. If there is a problem with the sealing performance at the connection, it indicates that the wear of the wear-resistant outer ring 201 may be severe, requiring maintenance or replacement.The adaptability controller 004 will illuminate an indicator light to remind relevant technicians, prompting them to perform timely maintenance. This ensures the filtration effect of the activated carbon filter assembly, further improving the practicality and reliability of the filter. The detection also ensures more thorough contact between the liquid and the activated carbon filter element 205, further enhancing the filtration effect and activated carbon utilization. Furthermore, the adaptability controller 004 and the wear detection and contact enhancement component can detect the wear of the wear-resistant outer ring 201 not only when the liquid flow rate is below the flow threshold but also when the liquid flow rate is above the flow threshold. This can be easily achieved by those skilled in the art through appropriate settings for the adaptability controller 004. The specific setting methods are well-known to those skilled in the art and will not be elaborated upon here.

[0036] Please see Figure 7 The outer side of the lifting cylinder 501 is provided with a cylinder waterproof cover 504. The output end of the lifting cylinder 501 passes through the cylinder waterproof cover 504 and is movably and sealed to it. The cylinder waterproof cover 504 can protect the lifting cylinder 501 and extend its service life.

[0037] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
