[0048] As Figures 1 to 15 The present application provides an activated carbon adsorption device, which comprises a housing 10, a plurality of activated carbon boxes 30, a liquid inlet pipe 73 and a plurality of closing members. The housing 10 is provided with a containing cavity, and the housing 10 is provided with liquid inlet holes 11 and liquid outlet holes 12 at intervals. The plurality of activated carbon boxes 30 are placed in the containing cavity, and each activated carbon box 30 is replaceably arranged. Each activated carbon box 30 is provided with a first interface 31 and a second interface 32 which communicate with the inside of the activated carbon box 30. The first interface 31 communicates with the liquid inlet hole 11, and the second interface 32 communicates with the liquid outlet hole 12. The liquid inlet pipe 73 comprises a main pipe 731 and a plurality of branch pipes 732 connected to the main pipe 731. The inlet of the main pipe 731 is connected to the liquid inlet hole 11. When the plurality of activated carbon boxes 30 are placed in the containing cavity, the plurality of branch pipes 732 are connected to the plurality of activated carbon boxes 30 one by one. The outlet of each branch pipe 732 communicates with the first interface 31 on the corresponding activated carbon box 30. The second interface 32 on each activated carbon box 30 communicates with the liquid outlet hole 12. The plurality of closing members are connected to the plurality of branch pipes 732 one by one. Each closing member opens or closes the corresponding branch pipe 732. The closing member of the present application is preferably a valve or a solenoid valve.

[0049] The technical scheme of the embodiment can simultaneously or successively open all the closing members, the solution enters into the shell 10 from the liquid inlet hole 11 and enters into the activated carbon tank 30 from the first interface 31, when passing through the activated carbon tank 30, the solution penetrates into the activated carbon in the activated carbon tank 30, after the activated carbon in the activated carbon tank 30 is adsorbed, the solution after being adsorbed passes through the second interface 32 and is discharged from the liquid outlet hole 12. When the activated carbon needs to be replaced, in order to ensure the safety of the replacement operation, the closing member corresponding to the activated carbon tank 30 that needs to be replaced is operated, the closing member closes the corresponding branch pipe 732, at this time, the solution cannot flow into the activated carbon tank 30 that needs to be replaced, but flows into other activated carbon tanks 30, the activated carbon in the other activated carbon tanks 30 continues to perform the wastewater treatment, without stopping, the operation of replacing the activated carbon can be performed, the activated carbon adsorption device is not affected to perform the wastewater treatment, and the efficiency of the wastewater treatment performed by the activated carbon adsorption device is improved. Therefore, the technical scheme of the embodiment effectively solves the problem of low efficiency of the wastewater treatment performed by the activated carbon adsorption device in the related art.

[0050] The end of the liquid inlet pipe 73 away from the liquid inlet hole 11 is detachably connected with the first interface 31. In this way, when the activated carbon tank 30 needs to be replaced, the liquid inlet pipe 73 can be quickly detached from the activated carbon tank 30 that needs to be replaced, after the replacement is completed, when the replaced activated carbon tank 30 is placed on the mounting frame 20 again, the end of the liquid inlet pipe 73 away from the liquid inlet hole 11 can be connected with the first interface 31 of the replaced activated carbon tank 30.

[0051] In the related art, the adsorption device includes a shell and an activated carbon adsorption tank arranged in the shell, the activated carbon is directly filled in the activated carbon adsorption tank, and the replacement of the activated carbon is performed by manually digging the activated carbon adsorption tank with a shovel, which has low replacement efficiency and high labor intensity. In addition, because the activated carbon adsorption tank adsorbs a large amount of toxic substances such as oil and heavy metals in the wastewater, the activated carbon saturated with adsorption is hazardous waste, manual replacement is easy to contact, and toxic particles are inhaled, which has an occupational health and safety risk.

[0052] The activated carbon is a carbon material collectively referred to as a carbon material with developed pores, a large specific surface area and rich surface chemical groups, and strong specific adsorption capacity, which is prepared by pyrolysis and activation of carbon-containing raw materials such as wood, coal and petroleum coke. When a fluid contacts a porous solid, a certain component or multiple components in the fluid are accumulated at the surface of the solid, which is called adsorption. Adsorption also refers to the phenomenon that a substance (mainly a solid substance) adsorbs molecules or ions in the surrounding medium (liquid or gas).

[0053] As shown in FIG. 1, the activated carbon adsorption device includes a shell 10, a mounting frame 20, a plurality of activated carbon tanks 30 and a plurality of closing members 70. Figures 1 to 6 , Figure 13 and Figure 15As shown, the activated carbon adsorption device further comprises a plurality of docking pieces 40, which are arranged on the plurality of activated carbon boxes 30 one by one, and each docking piece 40 can be docked with the fork arm of the forklift. When the activated carbon box 30 needs to be replaced, the fork arm of the forklift is inserted into the docking piece 40, and then the fork arm is moved, so that the activated carbon box 30 can be taken out of the shell 10 to be replaced. The replaced activated carbon box 30 can be placed in the shell 10 again by the forklift. In this way, during the replacement of the activated carbon box 30, manual contact with toxic particles is avoided. Moreover, the replacement efficiency is improved, and the labor intensity is reduced. Therefore, the technical scheme of the embodiment effectively solves the problem that the activated carbon adsorption column is easily contacted and inhales toxic particles in the related art.

[0054] In the embodiment, the activated carbon box 30 needs sufficient treatment flow, under which the fluid should have sufficient residence time in the activated carbon box 30. Without considering the resistance change in the long-term adsorption process of the activated carbon box 30, the main influencing factor of the residence time is the height of the activated carbon box 30. In addition, sufficient wetting of the activated carbon is required for adsorption. Under the condition that the flow cannot be increased unlimitedly, sufficient wetting requires that the cross-sectional area of the activated carbon box 30 be limited. The cross-sectional area needs to be small enough to match the corresponding flow, so that the activated carbon box 30 can be kept in a fully wet state during operation, ensuring that the production process does not appear short circuit. The ratio of the height to the cross-sectional area of the activated carbon box 30 is between 3 and 4 after simulation analysis, and is preferably 3 or 3.6 or 4. This can ensure that the fluid has sufficient residence time to fully remove organic matter and impurities in the fluid and improve the adsorption capacity, while also maximizing the adsorption efficiency and preventing short circuit.

[0055] As shown in Figures 1 to 6 , Figure 13 and Figure 15 , the shell 10 is provided with a first opening 13, and the activated carbon adsorption device further comprises a mounting rack 20 rotatably arranged in the shell 10. The mounting rack 20 is provided with a plurality of placement spaces 21, and the plurality of activated carbon boxes 30 are arranged in the plurality of placement spaces 21 one by one and on the mounting rack 20. The plurality of placement spaces 21 correspond to the first opening 13 alternately. The activated carbon box 30 is replaceably arranged on the mounting rack 20 and in the placement space 21. When the activated carbon box 30 needs to be replaced, the fork arm of the forklift is inserted into the docking piece 40 through the first opening 13, and then the fork arm is moved, so that the activated carbon box 30 can be taken out of the placement space 21 and from the mounting rack 20 to be replaced. The replaced activated carbon box 30 can be placed on the mounting rack 20 again by the forklift. In this way, during the replacement of the activated carbon box 30, manual contact with toxic particles is avoided. Moreover, the replacement efficiency is improved, and the labor intensity is reduced.

[0056] It should be noted that the placement space corresponds to the first opening 13 means that the outline of the placement space is located on the plane of the first opening 13. The activated carbon tank 30 is preferably a fan shape, and of course can also be a triangular shape. The width of the sealing door 14 in the following is greater than the maximum width of the fan shape, which can facilitate the removal and replacement of the activated carbon tank 30, and facilitate the cleaning and maintenance of the inside of the shell 10.

[0057] The "multiple" described in the present application means at least two. Of course, the activated carbon tank can also be one.

[0058] Specifically, the first opening 13 is arranged on the side of the shell 10, and the activated carbon tank 30 can be directly forked out from the side of the shell 10 through the first opening 13 for replacement, and four activated carbon tanks 30 can be replaced by four times of forking and taking back, wherein the four activated carbon tanks 30 correspond to the activated carbon adsorption tank in the background art. This greatly improves the replacement efficiency and reduces the labor intensity compared with the original manual shovel activated carbon adsorption tank method.

[0059] As shown in Figures 1 to 6 , Figure 13 and Figure 15 , the mounting rack 20 is rotatably arranged in the shell 10, and the mounting rack 20 is provided with four placement spaces 21. The four activated carbon tanks 30 are replaceably placed on the mounting rack 20, and the four activated carbon tanks 30 are one-to-one correspondingly located in the four placement spaces 21. Each activated carbon tank 30 is provided with a docking piece 40, and the four placement spaces 21 are alternatively corresponding to the first opening 13. When the four activated carbon tanks 30 are placed on the mounting rack 20, the first interface 31 on each activated carbon tank 30 is in communication with the liquid inlet hole 11, and the second interface 32 on each activated carbon tank 30 is in communication with the liquid outlet hole 12. In this way, when one of the four activated carbon tanks 30 is replaced, the mounting rack 20 can be rotated so that one of the four placement spaces 21 corresponds to the first opening 13. At this time, the docking piece 40 on the activated carbon tank 30 directly corresponds to the first opening 13, which facilitates the insertion of the two fork arms of the forklift into the first docking cylinder 41 and the second docking cylinder 42 through the first opening 13, and further facilitates the replacement of the activated carbon tank 30 by the forklift. After replacement, the mounting rack 20 can be rotated again, and the remaining activated carbon tanks 30 can be replaced by the forklift in turn.

[0060] As shown in Figure 5 , Figure 6 , Figure 13 and Figure 15As shown in the figure, the mounting rack 20 comprises a rotating shaft 22 rotatably arranged in the housing 10 and a plurality of mounting vertical plates 23 arranged at intervals on the rotating shaft 22, the plurality of mounting vertical plates 23 are arranged at equal angles along the circumference of the rotating shaft 22, and a placing space 21 is formed between each adjacent two mounting vertical plates 23. In order to enable the activated carbon box 30 to be stably mounted on the mounting rack 20, the mounting rack 20 further comprises a support 24 arranged on each mounting vertical plate 23, and the activated carbon box 30 is replaceably placed on the support 24.

[0061] As shown in the figure, Figure 5 , Figure 6 , Figure 13 and Figure 15 , the mounting rack 20 comprises a rotating shaft 22 rotatably arranged in the housing 10 and four mounting vertical plates 23 arranged at intervals on the rotating shaft 22. In order to facilitate the processing of the mounting rack and improve the replacement efficiency of the activated carbon box 30, the four mounting vertical plates 23 are arranged at equal angles along the circumference of the rotating shaft 22, and a placing space 21 is formed between each adjacent two mounting vertical plates 23. In order to enable the activated carbon box 30 to be stably mounted on the mounting rack 20, the mounting rack 20 further comprises a support 24 arranged on each mounting vertical plate 23, and the activated carbon box 30 is replaceably placed on the support 24.

[0062] In the embodiment, the activated carbon adsorption device further comprises a driving mechanism 80 for driving the mounting rack 20 to rotate. The driving mechanism 80 comprises a driving motor 81 arranged on the housing 10 and a gear transmission structure 82 connected between the motor shaft of the driving motor 81 and the top end of the rotating shaft 22.

[0063] As shown in the figure, Figures 12 to 15 , in order to enable the activated carbon box 30 to be quickly removed or placed from the mounting rack 20, a lapping piece 33 lapping with the support 24 is arranged on both sides of each activated carbon box 30, and a blocking piece 25 is arranged at the end of the support 24 away from the rotating shaft 22, and the lapping piece 33 can be blocked with the blocking piece 25. When the four activated carbon boxes 30 are placed on the mounting rack 20, the blocking piece 25 blocks the lapping piece 33, preventing the lapping piece 33 from shifting, and preventing the lapping piece 33 from falling off the support 24.

[0064] In the embodiment, the support 24 comprises a support plate or a support rib, the lapping piece 33 comprises a lapping plate or a lapping rib, and the blocking piece 25 comprises a blocking block or a blocking rib.

[0065] As shown in the figure, Figure 1 , Figures 5 to 11 and Figure 15As shown, a connector 53 is provided on the inner wall of the housing 10. The activated carbon adsorption device also includes a stop structure 60 provided on the connector 53. The stop structure 60 includes a stop rod 61 movably provided on the connector 53 and a reset member 62 provided between the stop rod 61 and the connector 53. In the rotation direction of the mounting bracket 20, the stop rod 61 has a stop position that cooperates with the stop of the docking member 40 and a clearance position that avoids the docking member 40. The reset member 62 applies a reset force to the stop rod 61 to keep the stop rod 61 in the stop position. When the stop rod 61 is in the stop position (e.g., ... Figure 7 When the trajectory shown by the solid line is reached, one of the multiple placement spaces 21 will stop at the position corresponding to the first opening 13. At this time, the mounting frame 20 stops rotating, making it easier for a forklift to replace the activated carbon box 30 in the placement space 21.

[0066] When the stop bar 61 is in the avoidance position (e.g.) Figure 7 When the trajectory shown by the dotted line is reached, the activated carbon box 30 rotates together with the mounting frame 20 within the placement space 21. Thus, after the activated carbon box 30 in the first placement space of the multiple placement spaces 21 is replaced, the mounting frame 20 continues to rotate. When it rotates to the position corresponding to the first opening 13 in the second placement space, due to the resetting force of the reset member 62, the stop bar 61 can automatically and promptly switch from the avoidance position to the stop position, facilitating the second placement space to stop at the position corresponding to the first opening 13, thereby facilitating the sequential replacement of the remaining activated carbon boxes 30 using a forklift.

[0067] Of course, in other embodiments, the stop bar 61 has a stop position that cooperates with the second docking cylinder 42 and a avoidance position that avoids the first docking cylinder 41 and the second docking cylinder 42.

[0068] In the embodiment, the activated carbon adsorption device further comprises a controller and a proximity switch 74 arranged on the stop rod 61, the proximity switch 74 and the driving motor 81 are connected with the controller, and the controller is preferably a PLC controller. When the first activated carbon tank 30 needs to be replaced, and when the proximity switch 74 detects that the stop rod 61 is in contact with the first docking cylinder 41 on the first activated carbon tank 30, the proximity switch 74 sends a stop signal to the controller, so that the controller controls the driving motor 81 to stop rotating, and when the stop rod 61 is in the stop position, the mounting rack 20 stops rotating. After the replacement of the first activated carbon tank 30 is completed, when the second activated carbon tank 30 is replaced, the proximity switch 74 sends a continue rotating signal to the controller, so that the controller controls the driving motor 81 to start rotating, and the mounting rack 20 continues to rotate, so that the first docking cylinder 41 and the second docking cylinder 42 on the first activated carbon tank 30 push the stop rod 61 in turn, so that the stop rod 61 is switched from the stop position to the avoiding position, and until the proximity switch 74 detects that the stop rod 61 is in contact with the first docking cylinder 41 on the second activated carbon tank 30, the proximity switch 74 sends a stop signal to the controller, so that the controller controls the driving motor 81 to stop rotating, so as to replace the second activated carbon tank 30, and the subsequent two activated carbon tanks 30 are replaced in turn. When the stop rod 61 is switched from the stop position to the avoiding position, the driving force of the driving motor 81 driving the mounting rack 20 to rotate is greater than the restoring force of the restoring member 62 applied to the stop rod 61 to keep the stop rod 61 in the stop position.

[0069] As shown in Figures 1 to 11 The stop structure 60 further comprises a connecting rod structure 63 hinged with the stop rod 61 and a lock column 64 movably arranged on the connecting rod structure 63 and the connecting piece 53. The first end of the stop rod 61 is hinged on the connecting piece 53, the hinged position of the connecting rod structure 63 and the stop rod 61 is between the first end of the stop rod 61 and the second end of the stop rod 61, the restoring member 62 is arranged between the connecting rod structure 63 and the connecting piece 53, the connecting piece 53 is provided with a lock hole 531, and the lock column 64 has a locked position in the lock hole 531 and an unlocked position away from the lock hole 531 when the lock column 64 moves relative to the connecting rod structure 63. When the lock column 64 is in the locked position, the stop rod 61 is kept in the stop position, so that the plurality of placement spaces 21 can be stably stopped in the position corresponding to the first opening 13, and the reliability of the stop structure 60 when playing a stop role is improved. In order to enable the stop rod 61 to drive the lock column 64, when the docking piece 40 pushes the stop rod 61 to switch from the stop position to the avoiding position, the stop rod 61 drives the lock column 64 on the connecting rod structure 63 to move, so that the lock column 64 is switched from the locked position to the unlocked position.

[0070] The above-mentioned restoring member 62 can be a torsional spring or a compression spring or two magnetic members generating repulsive force.

[0071] As shown in Figures 8 to 10 the bottom end of the lock post 64 is provided with a first guide inclined surface 641, and the top end of the lock hole 531 is provided with a second guide inclined surface 533 capable of guiding cooperation with the first guide inclined surface 641. In this way, during the process of switching the lock post 64 from the locked position to the unlocked position, the first guide inclined surface 641 on the lock post 64 slides along the second guide inclined surface 533, and the lock post 64 can smoothly escape from the lock hole 531. The first guide inclined surface 641 and the second guide inclined surface 533 can both be conical surfaces or inclined planes.

[0072] As shown in Figures 7 to 11 the connecting rod structure 63 includes a first rotating block 631 and a second rotating block 632 hingedly connected to the connecting platform at intervals, and further includes a first connecting rod 633 hingedly connecting the stop rod 61 and the first rotating block 631 together, and a second connecting rod 634 hingedly connecting the second rotating block 632 and the first rotating block 631 together. The first rotating block 631 is in the shape of a cam, and the second rotating block 632 is in the shape of a rhombus. The first rotating block 631 serves as a transition for transmitting force, facilitating the transmission of the acting force applied by the second connecting rod 634 and the first connecting rod 633. Moreover, the first rotating block 631 and the second rotating block 632 are distinguished by shape, facilitating installation and making the transmission of acting force more stable.

[0073] The first end of the reset member 62 is connected to the connecting platform, and the second end of the reset member 62 is connected to the second rotating block 632. Specifically, the reset member 62 is a torsion spring, the first torsion arm of the torsion spring is the first end of the reset member 62, and the second torsion arm of the torsion spring is the second end of the reset member 62. In this way, the torsion spring can be stably installed on the connecting platform and the second rotating block 632, and it is convenient to apply a torsion spring force to the second rotating block 632, so that the second rotating block 632 applies a reset force to the stop rod 61 through the second connecting rod 634, the first rotating block 631 and the first connecting rod 633, so that the stop rod 61 is kept in the stop position.

[0074] The lock post 64 is movably arranged on the second rotating block 632, and the lock post 64 and the second connecting rod 634 are respectively located at opposite ends of the second rotating block 632. The second rotating block 632 and the first rotating block 631 are arranged at intervals, which can reasonably arrange the stop rod 61, the second connecting rod 634, the first connecting rod 633, the reset member 62 and the lock post 64, and avoid interference with the vertical ribs when each works. The connecting platform is provided with an arc-shaped sliding groove 532 guiding cooperation with the lock post 64, and the lock hole 531 is located in the end of the arc-shaped sliding groove 532 away from the stop rod 61. During the switching process of the lock post 64 between the locked position and the unlocked position, the lock post 64 slides in the arc-shaped sliding groove 532, avoiding leaving scratches on the outer surface of the connecting platform.

[0075] As shown in Figures 7 to 11As shown, in order to facilitate the installation of the lock post 64 on the connecting rod structure 63 and make the lock post 64 movable relative to the connecting rod structure 63, the connecting rod structure 63 is provided with a mounting hole 635, and the lock post 64 is movably arranged in the mounting hole 635. When the lock post 64 moves to protrude out of the mounting hole 635 and extend into the lock hole 531, the lock post 64 is in the locked position. When the lock post 64 moves to be located in the mounting hole 635 and away from the lock hole 531, the lock post 64 is in the unlocked position. The activated carbon adsorption device further comprises an adjusting post 71 and an elastic member 72. The adjusting post 71 is movably arranged in the mounting hole 635 and is spaced apart from the lock post 64 along the axis of the mounting hole 635. The elastic member 72 is arranged between the adjusting post 71 and the lock post 64, and the elastic member 72 applies an elastic force to the lock post 64 to keep the lock post 64 in the locked position. The arrangement of the adjusting post 71 can adjust the elastic force applied by the elastic member 72 to the lock post 64 to keep the lock post 64 in the locked position through movement in the mounting hole 635, so that when the lock post 64 is stably in the locked position, the stop lever 61 can be reliably and stably kept in the stop position.

[0076] The elastic member 72 is preferably a compression spring or two magnetic members that generate repulsive force.

[0077] Specifically, the connecting rod structure 63 further comprises a mounting cylinder which is detachably arranged at one end of the second rotating block 632 away from the first rotating block 631. The second rotating block 632 is provided with a first hole section and a second hole section which are in communication with each other. The diameter of the first hole section is greater than that of the second hole section, and a stepped surface is formed between the first hole section and the second hole section. The elastic member 72 is arranged between the adjusting post 71 and the stepped surface. The inner hole of the mounting cylinder forms a third hole section, and the diameter of the third hole section is greater than that of the first hole section. The second hole section, the first hole section, and the third hole section are sequentially communicated to form the above-mentioned mounting hole 635. The lock post 64 is movably arranged in the first hole section and the second hole section, and the adjusting post 71 is movably arranged in the third hole section, and both are connected by threads.

[0078] In other embodiments, in order to facilitate processing and manufacturing, the abutting member 40 comprises a force receiving surface or an abutting cylinder or an abutting ring or an abutting protrusion or an abutting recess.

[0079] As shown in Figure 1 , Figures 5 to 9 The abutting member 40 comprises a first abutting cylinder 41 and a second abutting cylinder 42, and the first abutting cylinder 41 and the second abutting cylinder 42 are arranged on both sides of the activated carbon box 30, respectively. Two fork arms of a forklift are inserted into the first abutting cylinder 41 and the second abutting cylinder 42 through the first opening 13, respectively, and then the two fork arms are moved to drive the activated carbon box 30 to move away from the shell 10 to be removed from the shell 10 for replacement. The distance between the first abutting cylinder 41 and the second abutting cylinder 42 is equal to the distance between the two fork arms of the forklift.

[0080] AsFigure 1 , Figures 5 to 11 and Figure 15 As shown, the inner surfaces of the first docking cylinder 41 and the second docking cylinder 42 are rectangular. Thus, the inner surface of the rectangular first docking cylinder 41 is adapted to the shape of one fork arm of the forklift, and the inner surface of the rectangular second docking cylinder 42 is adapted to the shape of the other fork arm of the forklift. Therefore, after the two fork arms are inserted into the first docking cylinder 41 and the second docking cylinder 42 (referred to as the two docking cylinders), the docking cylinders can limit the relative range of movement of the fork arms within the cylinders, ensuring the smoothness of the forklift's picking action.

[0081] like Figure 1 , Figures 5 to 11 and Figure 15 As shown, the housing 10 has a first opening 13. The activated carbon adsorption device also includes a guide 50 disposed on the housing 10. The guide 50 includes a guide surface 51 located at the first opening 13, which is flush with the inner surfaces of the first docking cylinder 41 and the second docking cylinder 42. During the process of the two forks of the forklift being inserted into the first docking cylinder 41 and the second docking cylinder 42 respectively, the forks move along the guiding direction of the guide surface 51 towards the first docking cylinder 41 and the second docking cylinder 42 respectively, which facilitates the precise insertion of the two forks into the first docking cylinder 41 and the second docking cylinder 42 respectively, improves the smoothness of the forklift's picking action, and facilitates the removal and replacement of the activated carbon box 30 from the corresponding placement space 21.

[0082] like Figure 1 , Figures 5 to 11 As shown, the guide surface 51 includes a first guide plane 511 and a second guide plane 512 set at an angle. Both the first guide plane 511 and the second guide plane 512 are flush with the inner surfaces of the first docking cylinder 41 and the second docking cylinder 42. The first guide plane 511 and the second guide plane 512 have inclined guide surfaces 513 facing the first opening 13. During the insertion of the two forklift arms into the first docking cylinder 41 and the second docking cylinder 42, the first forklift arm is guided by the inclined guide surface 513 to a position aligned with the first docking cylinder 41. The first guide plane 511 and the second guide plane 512 guide the first forklift arm, preventing it from deviating from the guiding direction of the guide surface 51, thus ensuring that the first forklift arm can be accurately inserted into the first docking cylinder 41. Similarly, the second forklift arm can be accurately inserted into the second docking cylinder 42.

[0083] like Figures 7 to 11As shown, the guide member 50 further comprises a folded member 52 which is spaced apart from the inner side wall of the housing 10, a connecting member 53 is connected between the folded member 52 and the inner side wall of the housing 10, and the guide surface 51 is arranged on the folded member 52. The connecting member 53 comprises a connecting platform and a vertical rib connecting the connecting platform and the folded member 52, and the stop structure 60 further comprises a connecting rod structure 63 hinged with the stop rod 61 and a lock post 64 movably arranged on the connecting rod structure 63 and the connecting platform, and the first end of the stop rod 61 is hinged on the folded member 52. In this way, the guide surface 51, the stop rod 61, the reset member 62, the connecting rod structure 63 and the lock post 64 can be reasonably arranged on the guide member 50, so as to avoid mutual interference of the components during operation. In addition, the structural shape of the folded member 52 can ensure that the guide member 50 has sufficient structural strength and can stably guide the fork arm of the forklift.

[0084] The hinge between the connecting rod structure 63 and the stop rod 61 is located between the first end of the stop rod 61 and the second end of the stop rod 61. In this way, the first end of the stop rod 61 can rotate on the vertical rib, and the second end of the stop rod 61 can be stopped in cooperation with the first or second connecting sleeve 41 or 42.

[0085] The reset member 62 is arranged between the connecting rod structure 63 and the connecting platform, the connecting platform is provided with a lock hole 531, and the lock post 64 has a locked position in the lock hole 531 and an unlocked position away from the lock hole 531 when the lock post 64 moves relative to the connecting rod structure 63. When the lock post 64 is in the locked position, the stop rod 61 remains in the stop position.

[0086] As shown in Figure 2 , Figure 3 , Figure 12 and Figure 15 , the activated carbon tank 30 comprises a tank body 34, a second opening 35 arranged at the top of the tank body 34, and a tank cover assembly 36 arranged at the second opening 35, and the second interface 32 is arranged at the bottom of the tank body 34. The arrangement of the tank cover assembly 36 can prevent the overflow of the solution caused by the pressure difference in the tank body 34. The second interface 32 is arranged at the bottom of the tank body 34, and a filter cap 37 communicating the inside of the tank body 34 and the containing cavity is arranged at the second interface 32. The filter cap 37 can filter the solution after being adsorbed by the activated carbon in the activated carbon tank 30, and further filter, so as to ensure the adsorption effect of the activated carbon tank 30.

[0087] The box cover assembly 36 comprises a cover plate 361 which is openably and closably arranged at the second opening 35, a liquid distributor 362 arranged below the cover plate 361, and a connecting pipe 363 connected to the liquid distributor 362 and the cover plate 361, the first interface 31 is arranged at a first end of the connecting pipe 363, and a second end of the connecting pipe 363 is in communication with an inside of the liquid distributor 362. After the cover plate 361 is opened from the second opening 35, the activated carbon is directly filled into the box 34, and after the filling of the activated carbon into the box 34 is completed, the cover plate 361 is arranged at the second opening 35, the liquid distributor 362 moves together with the cover plate 361 and is placed into the inside of the box 34. In this way, the solution can enter into the liquid distributor 362 through the liquid inlet pipe 73, the liquid distributor 362 can uniformly distribute the solution, so that the solution can uniformly flow into the activated carbon in the box 34, and the activated carbon in the box 34 can be fully adsorbed.

[0088] The liquid distributor 362, the cover plate 361 and the connecting pipe 363 of the present embodiment are assembled into one body, which are convenient to be taken down or installed together, and the replacement of the activated carbon into the box 34 is facilitated, and the replacement efficiency is improved.

[0089] In the present embodiment, the replacement of the activated carbon box 30 can refer to replacing a new activated carbon box 30, or replacing the activated carbon in the activated carbon box 30 with new activated carbon.

[0090] As shown in Figures 1 to 5 In order to form a sealed containing cavity in the inside of the shell 10, the shell 10 is provided with a first opening 13, and a sealing door 14 is openably and closably arranged at the first opening 13.

[0091] In other embodiments, a sealing cover is openably and closably arranged at the first opening 13.

[0092] As shown in Figures 1 to 15 The specific process of the activated carbon adsorption device of the present embodiment is as follows:

[0093] The solution enters the box 34 through the liquid inlet pipe 73, and under the distribution of the liquid distributor 362 in the box 34, the solution can uniformly penetrate into the activated carbon. When the activated carbon is saturated, the liquid inlet pipe 73 can be quickly detached from the activated carbon box 30 that needs to be replaced. The sealing door 14 can be opened, and the controller controls the driving motor 81 to drive the rotating shaft 22 to rotate around the center of the shell 10. When the control mounting frame 20 is rotated to a position where the placement space 21 where the activated carbon box 30 that needs to be replaced is located corresponds to the first opening 13, and the proximity switch 74 detects that the stop rod 61 is in contact with the first docking cylinder 41 on the activated carbon box 30, the proximity switch 74 sends a stop signal to the controller to make the controller control the driving motor 81 to stop rotating. At this time, the stop rod 61 is in the stop position. When the forklift forks are inserted, the two fork arms of the forklift are respectively attached to the guide surfaces 51 of the left and right guide pieces 50, and the first docking cylinder 41 and the second docking cylinder 42 are accurately inserted, so that the activated carbon box 30 that needs to be replaced can be taken out for replacement. After replacement, the controller continues to control the driving motor 81 to drive the rotating shaft 22 to rotate around the center of the shell 10 to replace the remaining activated carbon boxes 30. When the rotating shaft 22 rotates around the center of the shell 10, the first docking cylinder 41 pushes the stop rod 61 to make way, so that the stop rod 61 is switched from the stop position to the avoidance position. When the first docking cylinder 41 is separated from the stop rod 61, the stop rod 61 is reset to the stop position under the action of the torsional spring. After resetting, the lock column 64 is clamped into the lock hole 531 by the arc-shaped sliding groove 532 under the action of the elastic force of the elastic member 72 on the lock column 64, so that the stop rod 61 is kept in the stop position.

[0094] In this way, the activated carbon adsorption device has high automation, the rotating shaft 22 is driven by the driving motor 81, and the activated carbon box is replaced by the forklift forks. The replacement efficiency is improved, and manual contact with hazardous activated carbon is avoided, thereby reducing the risk of inhaling toxic particles and the risk of harming the occupational health and safety of the operator.
