Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to heavy metal adsorption treatment equipment for industrial wastewater. Background Art

[0002] Industrial wastewater heavy metal adsorption treatment equipment is a special type of equipment used to remove heavy metal ions from industrial wastewater;

[0003] Currently, traditional industrial wastewater heavy metal adsorption treatment equipment continuously injects industrial wastewater containing various heavy metals into a tall adsorption tower through a pipe system. After the wastewater is injected, the equipment enters a relatively passive, static adsorption phase. During this phase, adsorbents such as activated carbon, which have been pre-filled in the adsorption tower, begin to play a key role. With its intricate microporous structure and huge specific surface area, activated carbon gradually absorbs heavy metals such as lead, mercury, and cadmium from the wastewater onto its surface and pores through intermolecular forces and chemical bonding.

[0004] However, in actual application scenarios, some operators, in pursuit of more efficient adsorption efficiency, attempt to stir the wastewater using mechanical stirring devices in an attempt to accelerate the contact between heavy metal ions and activated carbon. However, this measure is counterproductive. The strong shear force of the water flow generated by the stirring will forcibly peel off the heavy metal substances that have been firmly adsorbed by the micropores on the surface of the activated carbon. These detached heavy metal substances are mixed into the wastewater again, which disrupts the originally stable adsorption balance on the surface of the activated carbon. Not only can it no longer adsorb new heavy metal ions, but it also causes the already adsorbed heavy metal substances to return to the solution, thereby significantly reducing the activated carbon's adsorption effect on heavy metals. The wastewater is always in a relatively calm state in the adsorption tower. Lacking an effective flow and disturbance mechanism, the heavy metal ions in the wastewater can only rely on slow diffusion to gradually migrate to the surface of the activated carbon. This diffusion process is extremely slow, and it takes a long time for the heavy metal ions to reach the adsorption sites of the activated carbon, which in turn reduces the activated carbon's adsorption effect on heavy metal substances.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention uses a blower to eject bubbles from the pipe to drive the movement of the surrounding fluid, thereby promoting the diffusion of heavy metal substances to the surface of the activated carbon, shortening the distance and time for the heavy metal substances to reach the surface of the activated carbon, so that the activated carbon can more efficiently and fully contact the heavy metal substances, thereby significantly improving the adsorption effect of the activated carbon on the heavy metal substances, and driving the driving component to reciprocate the pipe, so that the heavy metal substances in the wastewater can be more widely and fully carried by the bubbles, thereby greatly increasing the opportunity for the heavy metal substances to contact the activated carbon, so that the heavy metal substances in the wastewater are cleaned more thoroughly;

[0027] The present invention links the extrusion block to slide toward the inside of the connecting pipe when the slider moves.

When the square plate moves, the square shell will be stretched, and then the square plate will enter the inside of the filter cartridge, thereby fixing the filter cartridge. Finally, the slider links the extrusion block to make the square plate enter the inside of the filter cartridge, and the entry can fix the filter cartridge, effectively preventing the filter cartridge from loosening or shifting due to water flow impact and equipment vibration during the wastewater treatment process, ensuring that the activated carbon is evenly and tightly distributed inside the filter cartridge, giving full play to its powerful adsorption performance, and efficiently capturing and removing heavy metal ions in industrial wastewater.

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0039] like Figures 1 to 9 As shown, the present invention provides an industrial wastewater heavy metal adsorption treatment device, including an adsorption tower 1 and a filter cartridge 10, and further comprising:

[0040] A rotating mechanism 2 is provided at the top of the adsorption tower 1;

[0041] The rotating mechanism 2 includes a sealing plate 201 provided at the top of the adsorption tower 1, a rotating block 202 is rotatably connected to the inside of the sealing plate 201, a blower 203 is fixedly installed on the top of the rotating block 202, a pipe 204 located inside the filter cartridge 10 is fixedly installed inside the rotating block 202, and the blower 203 and the pipe 204 are connected by a hose, a tooth plate 205 is fixedly installed on the top of the rotating block 202, and a rack 206 meshing with the tooth plate 205 is provided on the top of the adsorption tower 1;

[0042] The driving assembly 3 is disposed at the top of the rotating block 202 and is capable of driving the rack 206 to move.

[0043] The above scheme is adopted: the operator puts the activated carbon into the interlayer inside the filter cartridge 10, and installs the filter cartridge 10 inside the adsorption tower 1, then the sealing plate 201 can be installed on the top of the adsorption tower 1, and the pipe 204 enters the inside of the filter cartridge 10. At this time, the wastewater containing heavy metal substances can be injected into the inside of the adsorption tower 1, and then the blower 203 can be driven to compress the air, and then the compressed air will be discharged from the micropores on the surface of the pipe 204, thereby forming bubbles, and the generated bubbles will rise. When the bubbles rise, they will form tiny convection circulations, driving the surrounding fluid movement, and promoting the diffusion of heavy metal substances to the surface of the activated carbon. When the bubbles are discharged from the pipe 204, the drive component 3 can be driven to make the rack 206 move back and forth. Because the rack 206 is engaged with the tooth plate 205, the rack 206 will drive the tooth plate 205 to swing back and forth, and the tooth plate 205 will drive the rotating block 202 and the pipe 204 to rotate back and forth. Through the rotation of the pipe 204, the bubble ejection range is increased.

[0044] like Figure 4 and Figure 5 As shown, the driving assembly 3 includes a motor 1 301 fixedly connected to the top of the sealing plate 201, a rotating disk 302 is fixedly installed at the output end of the motor 1 301, a swing rod 303 is rotatably connected to the top of the sealing plate 201, a connecting block 2 305 located inside the swing rod 303 is fixedly installed at the top of the rack 206, and the connecting block 2 305 can slide inside the swing rod 303, and a connecting block 1 304 located inside the swing rod 303 is fixedly installed at the bottom end of the rotating disk 302, and the connecting block 1 304 can slide inside the swing rod 303.

[0045] Adopting the above scheme: through the design of the driving component 3, the motor 1 301 can be driven to rotate the rotating disk 302, and the rotating disk 302 will drive the connecting block 1 304 to slide inside the swing rod 303, and then the rotating disk 302 and the connecting block 1 304 will drive the swing rod 303 to rotate back and forth. When the swing rod 303 rotates, the connecting block 2 305 will slide inside the swing rod 303 and will push the connecting block 2 305 and the rack 206 to move back and forth, and the rack 206 will drive the tooth plate 205 to rotate back and forth.

[0046] like Figure 3 and Figure 6 As shown, it also includes:

[0047] The fixing mechanism 4 is arranged at the top of the sealing plate 201. The fixing mechanism 4 includes a fixed shell 401 fixedly connected to the top of the sealing plate 201. The fixed shell 401 is internally rotatably connected to the gear ring 402. The surface of the gear ring 402 is provided with a sliding groove 403. The sliding groove 403 is internally slidably connected to the slider 404. The top of the adsorption tower 1 is fixedly installed with a connecting block 3 405 located inside the sealing plate 201. The top of the slider 404 is fixedly installed with a plug plate 406 located inside the connecting block 3 405. The top of the fixed shell 401 is fixedly installed with a motor 2 407. The output end of the motor 2 407 extends to the inside of the fixed shell 401 and is fixedly installed with a gear 2 408 meshing with the gear ring 402.

[0048] Adopt the above scheme: through the design of the fixing mechanism 4, when the sealing plate 201 is installed on the top of the adsorption tower 1, the plug plate 406 can be inserted into the inside of the sealing plate 201, and the motor 2 407 can be driven to rotate the gear 2 408. Because the gear 2 408 is engaged with the gear ring 402, the gear 2 408 will drive the gear ring 402 and the sliding groove 403 to rotate, and the slider 404 will slide along the inner wall of the sliding groove 403. The slider 404 will drive the plug plate 406 to be inserted into the interior of the connecting block 3 405, thereby fixing the sealing plate 201 on the top of the adsorption tower 1.

[0049] like Figure 7 and Figure 8 As shown, it also includes:

[0050] The limiting mechanism 5 is arranged at the bottom end of the sealing plate 201. The limiting mechanism 5 includes a square shell 501 fixedly connected to the bottom end of the sealing plate 201. The square shell 501 is slidably connected to the inside of the square plate 502. The square shell 501 and the square plate 502 are elastically connected by an elastic member 503. A connecting tube 504 is fixedly installed on one side of the square shell 501. The connecting tube 504 is slidably connected to the inside of the extrusion block 505, and the top of the extrusion block 505 is fixedly connected to the bottom end of the slider 404.

[0051] The above solution is adopted: through the design of the limiting mechanism 5, when the slider 404 moves, the extrusion block 505 will be linked to slide toward the inside of the connecting tube 504, and when the extrusion block 505 moves, it will squeeze the air inside the connecting tube 504, and the compressed air will enter the inside of the square shell 501, and will push the square plate 502 to slide inside the square shell 501, and when the square plate 502 moves, the square shell 501 will be stretched, and then the square plate 502 will enter the inside of the filter cartridge 10, thereby fixing the filter cartridge 10.

[0052] like Figure 3 and Figure 9 As shown, it also includes:

[0053] The pop-up mechanism 6 is arranged at the bottom end of the adsorption tower 1. The pop-up mechanism 6 includes a mounting groove 601 fixedly connected to the bottom end of the adsorption tower 1. A circular shell 602 is fixedly installed inside the adsorption tower 1. The inside of the circular shell 602 is slidably connected with a connecting block four 603. The connecting block four 603 is elastically connected to the circular shell 602 through an elastic member two 604. The top of the connecting block four 603 is fixedly installed with a pushing block 605 located inside the mounting groove 601.

[0054] The above solution is adopted: through the design of the pop-up mechanism 6, when installing the filter cartridge 10, the bottom end of the filter cartridge 10 can be inserted into the installation groove 601. However, when installing the sealing plate 201, the filter cartridge 10 will be squeezed down, and the filter cartridge 10 will push the pushing block 605 to shrink into the inside of the installation groove 601, and when the pushing block 605 moves, the connecting block four 603 will squeeze the elastic part two 604. When it is necessary to remove the filter cartridge 10 and replace the activated carbon inside it, while opening the sealing plate 201, the compressed elastic part two 604 will push the connecting block four 603 and the pushing block 605, and the pushing block 605 will push the filter cartridge 10 out of the interior of the adsorption tower 1, thereby making it convenient for the operator to remove the filter cartridge 10.

[0055] like Figure 5 As shown, it also includes:

[0056] The sliding assembly 7 is arranged at the top of the sealing plate 201 . The sliding assembly 7 includes a square groove 701 opened at the top of the sealing plate 201 . A roller 702 located inside the rack 206 is rollingly connected inside the square groove 701 .

[0057] With the above solution, through the design of the sliding assembly 7, when the swing rod 303 pushes the rack 206 to move, it drives the roller 702 to roll inside the square groove 701, thereby enabling the rack 206 to move more smoothly.

[0058] like Figure 2 and Figure 6 As shown, it also includes:

[0059] The support assembly 8 is arranged inside the fixed shell 401. The support assembly 8 includes a support groove 801 opened inside the fixed shell 401. A support rod 802 is slidably connected inside the support groove 801, and one end of the support rod 802 is connected to the surface of the slider 404. The inside of the sealing plate 201 is fixedly connected to a damping block 9. There are multiple damping blocks 9, and the damping blocks 9 are arrayed around the rotating block 202. The surface of the damping block 9 is in contact with the surface of the rotating block 202.

[0060] The above solution is adopted: through the design of the support component 8, when the slider 404 slides along the inner wall of the sliding groove 403, it will drive the support rod 802 to slide on the inner wall of the support groove 801. Since the surface of the support rod 802 fits the inner wall of the support groove 801, the support groove 801 can limit the support rod 802, and the support rod 802 can support the slider 404. Through the design of the damping block 9, since the surface of the damping block 9 contacts the surface of the rotating block 202, when the rotating block 202 rotates, the resistance to the rotation of the rotating block 202 can be increased, ensuring that the rotating block 202 can rotate stably.

[0061] like Figure 5 and Figure 6 As shown, the bottom end of the swing rod 303 is fitted with the top end of the rack 206, and the surfaces of the connecting block 1 304 and the connecting block 2 305 are both smooth in design. There are four sliding grooves 403 and four sliders 404, and the sliding grooves 403 and the sliders 404 are arrayed on the surface of the fixed shell 401, and the sliding grooves 403 are curved in design.

[0062] The above scheme is adopted: through the design of the swing rod 303, connecting block 1 304 and connecting block 2 305, since the bottom end of the swing rod 303 fits with the top end of the rack 206, the rack 206 can be limited, so that the rack 206 will only move along the square groove 701, and the surfaces of connecting block 1 304 and connecting block 2 305 are designed to be smooth, so that the connecting block 1 304 and connecting block 2 305 can move more smoothly inside the swing rod 303. Through the design of the sliding groove 403 and the slider 404, since the number of the sliding grooves 403 and the slider 404 are both four, the stability of the fixation can be ensured, and the sliding groove 403 is designed to be curved, so the slider 404 will slide along the curved inner wall of the sliding groove 403, thereby driving the slider 404 to move.

[0063] The working principle and use of the present invention are smooth:

[0064] First, the operator places the activated carbon into the interlayer inside the filter cartridge 10 and inserts the filter cartridge 10 into the installation groove 601. Then, the sealing plate 201 can be installed on the top of the adsorption tower 1 and the inserting plate 406 can be inserted into the sealing plate 201. The motor 2 407 can be driven to rotate the gear 2 408. The gear 2 408 drives the gear ring 402 and the sliding groove 403 to rotate, and the slider 404 slides along the inner wall of the sliding groove 403. The slider 404 drives the inserting plate 406 to insert into the interior of the connecting block 3 405, thereby fixing the sealing plate 201 on the top of the adsorption tower 1.

[0065] When the slider 404 moves, the squeezing block 505 is linked to slide toward the inside of the connecting tube 504. When the squeezing block 505 moves, it squeezes the air inside the connecting tube 504 and the square shell 501, and pushes the square plate 502 to slide inside the square shell 501. When the square plate 502 moves, the square shell 501 is stretched, and then the square plate 502 enters the interior of the filter cartridge 10, thereby fixing the filter cartridge 10.

[0066] At this time, wastewater containing heavy metal substances can be injected into the interior of the adsorption tower 1, and then the blower 203 can be driven to compress the air, and then the compressed air will be discharged from the micropores on the surface of the pipe 204, thereby forming bubbles, and the bubbles will rise. When the bubbles rise, tiny convection circulation will be formed, driving the movement of the surrounding fluid, promoting the diffusion of heavy metal substances to the surface of the activated carbon, and facilitating the activated carbon to adsorb heavy metals in the wastewater. When the bubbles are discharged from the pipe 204, the motor 1 301 can be driven to rotate the rotating disk 302, and the rotating disk 302 and the connecting block 1 304 will drive the swing rod 303 to rotate back and forth. The swing rod 303 will push the connecting block 2 305 and the rack 206 to move back and forth, and the rack 206 will drive the tooth plate 205 to rotate back and forth, and the tooth plate 205 will drive the tooth plate 205 to swing back and forth, and the tooth plate 205 will drive the rotating block 202 and the pipe 204 to rotate back and forth. Through the rotation of the pipe 204, the bubble ejection range is increased, and the operation process is finally completed.

[0067] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
