The two ends of the rotating column are respectively embedded into the connecting grooves of the two brackets and slide in contact with them. The other end of the bracket passes through one side of the box and extends to the ground; a motor is fixedly installed inside the upper end of the box, and a belt is provided between the motor and the rotating column. The motor drives the rotating column through the belt.

[0011] Preferably, a fixing block is fixedly connected to the end of the support column away from the rotating column, and a fixing block is also fixedly connected to the end of another support column corresponding to the current support column. The two fixing blocks are also symmetrically arranged, and a support plate is slidably arranged between the two fixing blocks. One end of the third telescopic rod is fixedly connected to the side of the fixing block near the lower end, and the other end is fixedly connected to the side of the support plate. A limiting post is fixedly connected to the side of the other fixing block near the lower end. A placement groove is opened on the side of the support plate corresponding to the limiting post, and the limiting post passes through the placement groove of the limiting post.

[0012] Preferably, a fixing groove is provided on the upper part of the support plate near both ends, and a sensor patch is laid on the inner surface of the fixing groove. An activated carbon filter cylinder is placed on the upper part of the support plate. A protrusion matching the fixing groove is fixedly provided at the bottom of the activated carbon filter cylinder. Filter holes are provided on the activated carbon filter cylinder. Activated carbon is placed inside the activated carbon filter cylinder, and channels are set along both ends of the activated carbon filter cylinder.

[0013] Preferably, the internal storage space device of the support plate has several springs, each spring is provided with a round cover, the spring is fixedly connected to the bottom of the support plate, and the upper end of the spring is fixedly connected to the round cover.

[0014] Preferably, one of the fixing blocks is connected to the activated carbon filter cartridge with a first telescopic rod, and the other fixing block is connected to the activated carbon filter cartridge with a second telescopic rod.

[0022] 4. After confirming the position of the activated carbon filter cartridge, the system program will instruct the first and second telescopic rods to extend, and the limit plates on each rod to fix the activated carbon filter cartridge. No manual fixing of the activated carbon filter cartridge is required.

[0023] 5. During the removal process, the system program controls the spring and the round cover to pop out, causing the activated carbon filter cartridge to detach from the support plate. The first and second telescopic rods are automatically stretched and detached from the activated carbon filter cartridge under program control, simplifying the manual removal process of the activated carbon filter cartridge. Afterwards, the staff only needs to remove the activated carbon filter cartridge through the opening. Attached Figure Description

[0031] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0032] like Figure 1-6 As shown, an activated carbon decolorization device includes a box body 1. An opening 5 is provided at the upper end of the box body 1. A groove 6 is provided at the upper end of the box body 1 near the opening 5. A push-pull plate 7 is slidably disposed in the groove 6. A handle 71 is fixedly connected to the upper end face of the push-pull plate 7 near the front end. Pushing the handle 71 allows the push-pull plate 7 to slide relative to the box body 1 in the groove 6. At the same time, the internal condition of the box body 1 can be seen through the opening 5.

[0033] The upper end of the chamber 1 is also equipped with a water inlet pipe 2. The solution to be decolorized can flow into the chamber 1 from the water inlet pipe 2. After decolorization, the solution is discharged from the water outlet pipe 3 located at the front of the chamber 1. An observation window 4 is fixedly installed at the front of the chamber 1 to monitor the internal condition of the chamber 1 in real time.

[0034] The housing 1 is equipped with a rotating mechanism 8, which includes a rotating column 81 and several support columns 82. The rotating column 81 is installed at the center of the housing 1, and the support columns 82 are L-shaped. Several support columns 82 are symmetrically fixedly connected to both ends of the rotating column 81. The two support columns 82 at both ends of the rotating column 81 are correspondingly arranged and are on the same plane. When the rotating column 81 rotates, it can drive several support columns 82 to rotate together.

[0035] like Figure 2 , Figure 3As shown, brackets 11 are symmetrically arranged on both sides of the rotating column 81. A connecting groove is opened at one end of the bracket corresponding to the rotating column 81. The two ends of the rotating column 81 are respectively embedded into the connecting grooves of the two brackets 11 and slide in contact with them. The other end of the bracket 11 passes through one side of the box 1 and extends to the ground. This connection method is to allow the rotating column 81 to be installed inside the box 1 and rotate freely.

[0036] A motor 9 is fixedly installed inside the upper end of the housing 1. A belt 10 is installed between the motor 9 and the rotating column 81. The motor 9 drives the rotating column 81 through the belt 10. When the motor 9 is turned on, the rotating column 81 will rotate, and the rotating column 81 will drive several support columns 82 to rotate.

[0037] like Figure 2 , Figure 4 As shown, the end of the support column 82 away from the rotating column 81 is fixedly connected to the fixing block 13. The end of another support column 82, which is set corresponding to the current support column 82, is also fixedly connected to the fixing block 13. The two fixing blocks 13 are also symmetrically arranged. A support plate 14 is slidably arranged between the two fixing blocks 13. A third telescopic rod 15 is connected to one of the fixing blocks 13 and the support plate 14. One end of the third telescopic rod 15 is fixedly connected to the side of the fixing block 13 near the lower end, and the other end is fixedly connected to the side of the support plate 14. When the third telescopic rod 15 extends or retracts, the support plate 14 can slide between the two symmetrically arranged fixing blocks 13. In order to prevent the fixing block 13 from deviating from the direction during the sliding process, a limiting post 19 is fixedly connected to the side of the other fixing block 13 near the lower end. A placement groove is opened on the side of the support plate 14 corresponding to the limiting post 19. The limiting post 19 passes through the placement groove of the limiting post 19.

[0038] like Figure 4 , Figure 5 As shown, a fixing groove 22 is provided on the upper part of the support plate 14 near both ends. The inner surface of the fixing groove 22 is covered with a sensor patch 221. An activated carbon filter cartridge 24 is placed on the support plate 14. A protrusion matching the fixing groove 22 is fixedly provided at the bottom of the activated carbon filter cartridge 24. The protrusion can be embedded into the fixing groove 22, so that the activated carbon filter cartridge 24 can be placed stably on the support plate 14 without shaking. The sensor patch 221 will send a signal to confirm that the protrusion has been embedded into the fixing groove 22.

[0039] like Figure 5 , Figure 6As shown, the internal storage space of the support plate 14 contains several springs 23. Each spring 23 has a round cover 21 on top. The spring 23 is fixedly connected to the bottom of the support plate 14, and the upper end of the spring 23 is fixedly connected to the round cover 21. The system program controls the stretching of the spring 23. The system program can control the spring 23 to pop out along with the round cover 21, so that the protrusion of the activated carbon filter cartridge 24 is disengaged from the fixing groove 22. Alternatively, the system program can control the spring 23 to reset with the round cover 21, and the round cover 21 fits the lower curved surface of the activated carbon filter cartridge 24.

[0040] The activated carbon filter cartridge 24 has filter holes, activated carbon is placed inside the activated carbon filter cartridge 24, and a channel 241 is provided inside the activated carbon filter cartridge 24, which is arranged along both ends of the activated carbon filter cartridge 24.

[0041] Furthermore, side plates 16 are fixedly connected to the front and rear of the support plate 14 near the upper end. Both side plates 16 are inclined and the space formed by the two side plates 16 is adapted to the opening 5.

[0042] like Figure 4 As shown, one of the fixing blocks 13 is connected to the activated carbon filter cartridge 24 with a first telescopic rod 17, and the other fixing block 13 is connected to the activated carbon filter cartridge 24 with a second telescopic rod 20. One end of the first telescopic rod 17 is fixedly connected to the side of one of the fixing blocks 13 near the upper end, and part of the first telescopic rod 17 is embedded in the channel 241. One end of the second telescopic rod 20 is fixedly connected to the side of the other fixing block 13 near the upper end, and part of the second telescopic rod 20 is embedded in the channel 241. The end of the first telescopic rod 17 entering the channel 241 engages with the end of the second telescopic rod 20, so that the first telescopic rod 17 and the second telescopic rod 20 will not be misaligned. The system program uses this engagement relationship to determine that the first telescopic rod 17 and the second telescopic rod 20 have completed their extension and retraction.

[0043] To further limit the movement of the activated carbon filter cartridge 24, two limiting plates 18 are attached to the upper ends of the activated carbon filter cartridge 24. The lower end face of the limiting plate 18 is adapted to the curved surface of the activated carbon filter cartridge 24. The side of the limiting plate 18 is fixedly connected to the connecting post 181. One connecting post 181 is fixedly connected to the first telescopic rod 17, and the other connecting post 181 is fixedly connected to the second telescopic rod 20. When the first telescopic rod 17 and the second telescopic rod 20 extend or retract, the corresponding limiting plate 18 can be moved away from the curved surface of the activated carbon filter cartridge 24 through the connecting post 181, or the corresponding limiting plate 18 can be moved to fit against the curved surface of the activated carbon filter cartridge 24.

[0044] The third telescopic rod 15, the first telescopic rod 17, and the second telescopic rod 20 are all composed of several nested cylinders. Small cylinders are nested inside medium cylinders, and medium cylinders are nested inside large cylinders, forming the first telescopic rod 17, the second telescopic rod 20, and the third telescopic rod 15 in sequence. The first telescopic rod 17, the second telescopic rod 20, and the third telescopic rod 15 are all electro-hydraulic push rods, and their input ends are electrically connected to the output end of the external system program.

[0045] Furthermore, several drainage plates 12 are fixedly installed on the rotating column 81. The rotation of the rotating column 81 drives the drainage plates 12 to rotate together, so that the liquid in the center is discharged to the surrounding area and is more effectively decolorized by the activated carbon filter cartridges around it.

[0046] Working principle:

[0047] When the activated carbon filter cartridge 24 needs to be replaced, push the handle 71 and observe the inside of the housing 1. When the space formed by the side plates 16 on both sides of the activated carbon filter cartridge 24 that needs to be replaced reaches the fitting range of the opening 5, turn off the motor 9 or reduce the speed of the motor 9. The system program controls the extension and retraction of the first telescopic rod 17 and the second telescopic rod 20. The first telescopic rod 17 and the second telescopic rod 20, which were originally in the channel 241 of the activated carbon filter cartridge 24, partially leave the channel 241. The first telescopic rod 17 and the second telescopic rod 20 drive the corresponding limiting plate 18 to leave the curved surface of the activated carbon filter cartridge 24. The system program controls the spring 23 to pop out together with the round cover 21, so that the protrusion of the activated carbon filter cartridge 24 disengages from the fixing groove 22. At this time, the activated carbon filter cartridge 24 is in the disengaged state. At this time, the staff can take out the activated carbon filter cartridge 24 through the opening 5.

[0048] Then, slide down the inclined surface of any side plate 16 from the opening 5. When the sensing patch 221 does not detect the protrusion at the bottom of the activated carbon filter cartridge 24, it will send a signal. The signal is then received by the system program, which instructs the third telescopic rod 15 to extend and retract until the protrusion at the bottom of the activated carbon filter cartridge 24 corresponds to the fixing groove 22 and is embedded in it. The extension and retraction of the third telescopic rod 15 ends. Then, the system program instructs the ends of the first telescopic rod 17 and the second telescopic rod 20 to extend into the channel 241 until the first telescopic rod 17 and the second telescopic rod 20 are sensed to be engaged with each other. The system program then ends its instructions. During the extension process, the first telescopic rod 17 and the second telescopic rod 20 drive the corresponding limiting plate 18 to fit against the curved surface of the activated carbon filter cartridge 24 through the connecting column 181. The fixing process of the activated carbon filter cartridge 24 is completed.

[0049] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
