DETAILED DESCRIPTION

[0020] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1 like Figure 1 to Figure 10 As shown, this embodiment proposes a multi-stage adsorption wastewater treatment device, comprising: A water inlet box 1, the top of which is fixedly connected to an extension frame 2, the bottom end of one of the extension frames 2 is slidably connected to a blocking plate 3 for blocking the bottom end of the water inlet box 1, the middle of the blocking plate 3 is fixedly connected to a water inlet pipe 4, and the top of the water inlet pipe 4 is fixedly connected to a plurality of water distribution pipes 5; A water outlet box 6, which is fixedly connected between the top ends of the two extension frames 2, a water outlet pipe 7 is fixedly connected to the top end of the water outlet box 6, and a balancing plate 8 is provided at the top end of the interior of the water outlet box 6; The filter box 9 is installed between the water outlet box 6 and the water inlet box 1. The filter box 9 is filled with a water filter filler 10. The top and bottom of the filter box 9 are provided with a locking groove 11. A locking assembly 12, the locking assembly 12 is assembled between another extension frame 2, the water inlet box 1 and the water outlet box 6, and the locking assembly 12 is used to cooperate with the locking groove 11 to lock the filter box 9; In this embodiment, a linear slide bar 32 is slidably connected to the bottom end of one of the extension frames 2, and the bottom end of the linear slide bar 32 is fixedly connected to the blocking plate 3. By setting the linear slide bar 32, the displacement of the blocking plate 3 can be effectively limited to prevent the blocking plate 3 from sliding uncontrollably. In this embodiment, the edge of the bottom end of the water inlet tank 1 and the edge of the top of the blocking plate 3 are fixedly connected with a sealing strip, and the material of the sealing strip is flexible rubber. By setting the sealing strip, the connection gap between the water inlet tank 1 and the blocking plate 3 can be blocked to prevent wastewater from overflowing from the connection between the water inlet tank 1 and the blocking plate 3; In this embodiment, a plurality of spray ports are provided at the bottom end of the water distribution pipe 5, and a spray pipe is fixedly connected to the inside of each spray port. By setting the spray ports and the spray pipe, the liquid entering the water distribution pipe 5 can be sprayed over a wider range. Since the spray pipe is downward, when spraying water, the wastewater moves downward on the water inlet tank 1 and the blocking plate 3 in a relatively uniform manner. After hitting the blocking plate 3, a reaction force to the surrounding and upward direction is generated. At the same time, the kinetic energy carried by the wastewater itself will also cause it to start to diffuse in all directions in the blocking plate 3 area. In this embodiment, a feedback window 33 is provided on one side of the filter box 9, and an observation plate made of a transparent material is fixedly connected to the inside of the feedback window 33. By setting the feedback window 33, the adsorption condition of the locking groove 11 can be intuitively fed back to ensure the application effect of the locking groove 11; In this embodiment, a force-bearing handle 34 is fixedly connected to one end of the filter box 9 near the feedback window 33, and a gripping sleeve is fixedly connected to the outer side of the force-bearing handle 34. There are two force-bearing handles 34, which are located at both ends of the filter box 9. By using the force-bearing handles 34, personnel can hold the filter box 9 with the help of the force-bearing handles 34, making it more convenient to disassemble and assemble the filter box 9. In this embodiment, the top and bottom of the filter box 9 near one end of the limiting slide rail 36 are fixedly connected to the limiting slide rail 36, and one end of the water inlet box 1 and the water outlet box 6 are fixedly connected to the limiting slide rail 36, and the limiting slide rail 35 is also slidably connected to the outside of the limiting slide rail 36. By using the setting of the limiting slide rail 35 and the limiting slide rail 36, when the filter box 9 is assembled, the limiting slide rail 35 is first aligned with the limiting slide rail 36, and the filter box 9 is pushed, so that the limiting slide rail 35 slides at the limiting slide rail 36 to guide the filter box 9; In this embodiment, the material of the water filter filler 10 can be one or more of quartz sand, anthracite, activated carbon, glass fiber and garnet, wherein: Quartz sand is a granular solid material with good filtering properties. It can effectively remove impurities such as suspended matter and silt in water; Anthracite has good adsorption capacity and can effectively remove pollutants such as organic matter and heavy metals in water; Activated carbon has good adsorption properties and can effectively remove odor, color, and taste from water; Glass fiber has good filtering properties and can effectively remove suspended matter and particulate matter in water; Garnet has good filtering properties and can effectively remove impurities such as suspended matter and silt in water; By setting the water filter filler 10, when the wastewater moves from the water inlet box 1 to the filter box 9, the existence of the water filter filler 10 will produce a certain resistance to the water flow, but it will also affect the path and flow mode of the water flow. Since there are certain pore gaps between the water filter fillers 10, the wastewater will flow in the pores. During the adsorption process, as the water filter filler 10 adsorbs pollutants, local concentration differences will occur. These differences will further promote the continuous diffusion and flow of wastewater in the water filter filler 10, and push the wastewater to continue to move upward toward the water outlet box 6; When the wastewater enters the water outlet box 6, the equalizing plate 8 will further guide and balance the water flow, and the small holes and gaps on the equalizing plate 8 will make the water flow more evenly distributed in the top area, so that the wastewater can flow out in a relatively uniform state; The locking assembly 12 includes a positioning plate 14, an extension seat 15, a linkage shaft 16, a stabilizing plate 17 and an eccentric plate 18. A carrying cavity 13 is provided between the inner wall and the outer wall of the water inlet box 1 and the water outlet box 6. The positioning plate 14 is slidably connected inside the carrying cavity 13, and the positioning plate 14 is snap-connected with the locking groove 11. Both ends of the water inlet box 1 and the water outlet box 6 are fixedly connected with the extension seat 15, and the linkage shaft 16 is rotatably connected between the corresponding extension seats 15. The outer side of the linkage shaft 16 is fixedly connected with the stabilizing plate 17, one end of the linkage shaft 16 is fixedly connected with the eccentric plate 18, and the end of the eccentric plate 18 away from the linkage shaft 16 is rotatably connected with the linkage plate 19; A notch communicating with the carrying chamber 13 is provided on one side of the water inlet box 1 and the water outlet box 6. The end of the linkage plate 19 away from the eccentric plate 18 is also rotatably connected to the positioning plate 14. The end of the positioning plate 14 close to the notch is fixedly connected to a transmission plate 20. The inner side of the other extension frame 2 is rotatably connected to a transmission shaft 21. The top and bottom ends of the outer side of the transmission shaft 21 are provided with threaded sections 22. The thread rotation directions of the two threaded sections 22 are opposite, and the two transmission plates 20 are respectively threadedly connected to the outer sides of the two threaded sections 22. The bottom end of the inner side of the other extension frame 2 is also provided with an adjustment component, which is used to drive the blocking plate 3 to move; In this embodiment, a stabilizing frame is fixedly connected to the middle of another extension frame 2, and the transmission plate 20 is also rotatably connected to one end of the stabilizing frame through a ball bearing; In this embodiment, one end of the positioning plate 14 close to the notch is fixedly connected with a linkage pin, and one end of the linkage plate 19 away from the eccentric plate 18 is rotatably connected to the outer side of the corresponding linkage pin; Example 2 like Figure 1 to Figure 10 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes an adjustment component; In this embodiment, the adjustment component includes a guide shaft 23, a transmission screw 24, a matching bevel gear 25, a displacement cylinder 26, a transmission spur gear 27 and a locking cylinder 28. The bottom end inside the other extension frame 2 is rotatably connected with the guide shaft 23, the middle part of the guide shaft 23 is threadedly connected with the transmission screw 24, and the bottom end of the transmission screw 24 is fixedly connected to the blocking plate 3, the outer side of the guide shaft 23 is fixedly connected with the matching bevel gear 25, the bottom end of the outer side of the transmission shaft 21 is vertically slidably connected with the displacement cylinder 26, the outer side of the displacement cylinder 26 is fixedly connected with the transmission spur gear 27, and the transmission spur gear 27 is meshed with the matching bevel gear 25, the top end of the outer side of the displacement cylinder 26 is fixedly connected with the locking cylinder 28, one end of the locking cylinder 28 is threadedly connected with the transmission screw 29, and one end of the transmission screw 29 located inside the locking cylinder 28 is rotatably connected with the contact plate 30; In this embodiment, the pitch of the drive screw 24 is greater than the pitch of the threaded segment 22; In this embodiment, the top end of the locking cylinder 28 is fixedly connected to a limiting slide bar 31, and the contact plate 30 is also slidably connected to the limiting slide bar 31. The setting of the limiting slide bar 31 can support the displacement of the contact plate 30 to prevent the limiting slide bar 31 from rotating with the locking cylinder 28.

[0022] A specific application of the above two embodiments is that the bottom end of the water inlet pipe 4 is first connected to the wastewater pipe through a hose, and the wastewater is subsequently injected into the water distribution pipe 5 through the water inlet pipe 4, and sprayed downward through the water distribution pipe 5. After hitting the blocking plate 3, a reaction force to the surrounding and upward direction is generated. At the same time, the kinetic energy carried by the wastewater itself will also cause it to start to diffuse in all directions in the blocking plate 3 area. The wastewater will subsequently enter the water filter filler 10 and be purified by the water filter filler 10. The purified liquid continues to rise, and finally the liquid is balanced by the equalizing plate 8, and then flows out in a uniform state through the water outlet pipe 7; When the filtering effect of the water filter filler 10 is not good, the transmission shaft 21 is first rotated, and the setting of the threaded sections 22 with opposite threads on the transmission shaft 21 can drive the two transmission plates 20 to move away from each other, and then drive the positioning plate 14 to slide inside the carrying chamber 13 until the positioning plate 14 is moved out of the locking groove 11 and stored in the carrying chamber 13. Since the linkage plate 19 is connected between the eccentric plate 18 and the positioning plate 14, when the positioning plate 14 is displaced, the eccentric plate 18 can be pushed by the linkage plate 19. Since the eccentric plate 18 is supported by the linkage shaft 16, the linkage shaft 16 can be driven to flip, causing the linkage shaft 16 to disengage from the filter box 9, thereby releasing the positioning of the filter box 9, and then the filter box 9 is moved out from between the water inlet box 1 and the water outlet box 6 to replace the water filter filler 10. The guide shaft 23 can be rotated, and the connection between the guide shaft 23 and the transmission screw 24 can be coordinated, so that the transmission screw 24 can be vertically displaced at the guide shaft 23, so as to push the blocking plate 3 away from the water inlet tank 1 under the limit of the linear slide rod 32, so as to expose the blocking plate 3, and then the wastewater impurities at the blocking plate 3 can be cleaned. When the water filter filler 10 and the blocking plate 3 need to be cleaned at the same time, the transmission screw 29 can be rotated, and the connection between the transmission screw 29 and the locking cylinder 28 can be coordinated, so that the transmission screw 29 can be displaced along the locking cylinder 28, so as to push the contact plate 30 away from the transmission shaft 21, and then Reduce the friction between the displacement cylinder 26 and the transmission shaft 21, then pull the displacement cylinder 26 to adjust the position of the transmission spur gear 27 until the transmission spur gear 27 is meshed with the matching bevel gear 25, and then turn the transmission screw 29 to make the contact plate 30 fit tightly with the transmission shaft 21. Then, when the transmission shaft 21 rotates, the matching bevel gear 25 can be moved by the transmission spur gear 27, thereby driving the guide shaft 23 to rotate, so that the blocking plate 3 is away from the water inlet box 1, and the linkage shaft 16 and the positioning plate 14 release the positioning of the filter box 9, thereby greatly improving the overall maintenance efficiency; In summary, the uniform water distribution of the water distribution pipe 5 makes the adsorption of the water filter filler 10 more sufficient and efficient, the multi-stage adsorption process of the water filter filler 10 further improves the removal rate of pollutants, and the setting of the equalizing plate 8 makes the quality of the treated wastewater stable and meet the requirements. The gradual improvement of the wastewater treatment effect achieved through adsorption treatment in different areas and at different stages is the core embodiment of multi-stage adsorption.

[0023] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
