Description

Technical Field

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

[0002] Industrial production processes generate a significant amount of wastewater and waste liquid. Depending on the type of processing and wastewater, some industrial wastewater may contain heavy metals. For industrial wastewater containing heavy metals, adsorbents are typically used during treatment. Common heavy metal adsorbents include inorganic adsorbents, hydroxylated adsorbents, and carbonaceous adsorbents.

[0003] Patent publication number CN222082549U is a device for adsorbing heavy metal ion pollutants in industrial wastewater. Its structure mainly includes a filter box and an adsorption box. A connecting pipe is connected between the filter box and the adsorption box. A filter plate is installed on the side of the filter box close to the connecting pipe. A stirring shaft and a placement frame are provided in the adsorption box. The wastewater moves from the filter box to the adsorption box, and after being filtered, the wastewater enters the adsorption box, and is mixed with a flocculant through the stirring shaft, and is adsorbed by the adsorbent in the placement frame.

[0004] The above-mentioned device can filter, treat flocculants and adsorbents on wastewater, but there will still be fine impurities in the wastewater after adsorption treatment, so the treatment effect is poor, and the adsorbent placed in the frame is only located on one side of the adsorption box, resulting in insufficient contact between the wastewater and the adsorbent, and poor adsorption effect.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Example 1, please refer to the accompanying drawings, the present invention provides a technical solution: An industrial wastewater heavy metal adsorption treatment equipment, such as Figure 1 As shown, it includes a base 100, support rods 301 fixed at the four corners of the top surface of the base 100, and a cover plate 300 fixed to the top ends of the four support rods 301; like Figure 2 As shown, a vertical fixed cylinder 302 is fixed at the center of the cover plate 300, and a rotating filter assembly is provided at the bottom of the fixed cylinder 302. The bottom of the rotating filter assembly is provided with a transmission structure, and a wastewater transfer assembly is provided around the upper outer portion. A cylindrical inner box 400 is provided below the cover plate 300. A filter element assembly is fixed in the middle of the bottom of the inner box 400. The bottom of the filter element assembly is fixedly connected to the base 100 through a bracket, and the bottom surface of the inner box 400 corresponding to the annular area outside the filter element assembly is set as a conical surface, so that the wastewater is concentrated in the middle of the bottom of the inner box 400, which is convenient for subsequent transfer and transportation. A stirring assembly is provided in the inner box 400, and the top of the stirring assembly is correspondingly connected to the transmission structure. The middle bottom of the wastewater transfer assembly is connected to the wastewater conveying assembly, and the bottom end of the wastewater conveying assembly passes through the center of the stirring assembly and is close to the bottom of the inner box 400. A cylindrical outer box 200 is provided on the outside of the inner box 400, and an adsorbent is filled between the outer box 200 and the inner box 400. The outer side of the outer box 200 is connected to the base 100 through a lifting structure, and a vibration component is provided on the base 100 at a position corresponding to the outer box 200; like Figure 3 As shown, an annular vertical plate 309 is fixed to the bottom of the cover plate 300, and the annular vertical plate 309 contacts the upper part of the inner wall of the outer box body 200, and a horizontal annular pressing plate 310 is fixed at the bottom end corresponding to the position between the outer box body 200 and the inner box body 400. The pressing plate 310 is evenly distributed with through holes to compact and limit the top of the filled adsorbent to prevent the adsorbent from shifting under the flushing of wastewater. A moving cylinder 203 is provided in the middle of the bottom of the outer box body 200, and the bottom surface of the outer box body 200 is inclined toward the moving cylinder 203. A horizontal annular bottom plate 204 is fixed on the inner side of the bottom end of the moving cylinder 203, and an annular sealing plate 403 is fixed on the middle part of the outer side of the filter element assembly, and is in contact with the top of the annular bottom plate 204 through the sealing plate 403. The top surface of the sealing plate 403 is inclined toward the side wall direction of the moving cylinder 203.

[0023] When treating industrial wastewater containing heavy metals, the wastewater that has been treated by coarse filtration is transported to the rotary filter assembly through an external pump and pipeline equipment. The centrifugal action of rotation accelerates the filtration speed and improves the filtration effect, and the filtered impurities are accumulated in the rotary filter assembly for subsequent cleaning. The filtered wastewater falls to the bottom of the inner box 400, and the sewage treatment agent is added into the inner box 400. When the rotary filter assembly rotates, the stirring assembly rotates through the transmission structure, thereby fully stirring and mixing the sewage and the treatment agent, thereby achieving the chemical treatment operation of the treatment agent; The mixed wastewater is transported upward through the wastewater transport assembly, enters the wastewater transfer assembly, and falls to the position between the inner box 400 and the outer box 200. During the process of flowing downward along the space between the inner box 400 and the outer box 200, the wastewater is fully in contact with the adsorbent, so that heavy metals and the like are adsorbed; The wastewater after adsorption treatment enters the interior of the filter element assembly through the upper part thereof and is filtered through the filter element 405 to achieve fine filtration of the wastewater, further improving the treatment effect of the wastewater and facilitating subsequent recycling, treatment and discharge operations.

[0024] After the equipment has been working for a certain period of time, the adsorbent is replaced during the period of stopping. During replacement, the outer box body 200 is moved down by the lifting structure and contacts with the vibration component, and the sealing plate 403 is moved up relative to the moving cylinder 203 until it is detached, thereby opening the bottom end of the moving cylinder 203, and the adsorbent inside the outer box body 200 is discharged outward along the bottom end of the moving cylinder 203. At the same time, the outer box body 200 is vibrated by the vibration component to speed up the discharge of the adsorbent and reduce the adhesion and residue of the adsorbent.

[0025] When cleaning and maintaining the structures in the equipment, the cover plate 300 can be removed from the support plate, and then the rotary filter assembly, wastewater transfer assembly and transmission structure can be taken out from the inner box 400. Then the stirring assembly and wastewater conveying assembly can be removed, and the inner box 400, outer box 200, filter element assembly and disassembled structures can be cleaned and maintained. After the maintenance is completed, the structure in the inner box 400 is installed, and then the outer box 200 is moved back to its position through the lifting structure, and the adsorbent is filled, and then the cover 300 and the structure above it are installed back to their position. At the same time, the connection is re-realized through the transmission structure, etc., so that subsequent wastewater treatment work can be carried out.

[0026] The wastewater movement path in the present invention first moves from top to bottom for filtration and treatment agent mixing, and then moves from bottom to top to the bottom of the outer box, and then moves from top to bottom again, undergoing adsorption treatment with the adsorbent and filter element treatment. The wastewater moves up and down repeatedly, increasing the movement path, fully treating the wastewater, and reducing the overall volume of the equipment.

[0027] Among them, such as Figure 2 、 Figure 3 、 Figure 10 As shown, the wastewater transfer assembly includes a central tube 607 vertically located at the center of the fixed cylinder 302. The bottom end of the central tube 607 passes through the rotary filter assembly and is connected to the top of the wastewater conveying assembly. A plurality of conveying connecting tubes 606 are evenly fixed along the circumferential direction on the upper side wall of the central tube 607. The conveying connecting tubes 606 are fixedly connected to the side wall of the fixed cylinder 302, and the outer ends of the plurality of conveying connecting tubes 606 pass through the fixed cylinder 302 and are jointly fixed with a conveying ring tube 605. The conveying ring pipe 605 includes a plurality of straight pipe sections evenly arranged along the circumferential direction, with two adjacent straight pipe sections connected by an arc-shaped pipe section. A through hole is provided in the middle of the straight pipe section of the conveying ring pipe 605, and the through hole extends from the middle of the outer side of the straight pipe section to the middle of the bottom. A rotating transverse pipe 603 is provided on the outer side of the straight pipe section. A water outlet short pipe 604 is connected and fixed to the middle of the rotating transverse pipe 603. A pipe groove 401 is provided at the top of the inner box 400 corresponding to the position of each water outlet short pipe 604. Two brackets are provided at the bottom of the cover plate 300, and the two ends of the rotating transverse pipe 603 are rotatably connected to the brackets. Flip gears 602 are symmetrically fixed on both sides of the rotating horizontal tube 603. A vertical rack 601 is engaged on one side of each flip gear 602. The top ends of multiple racks 601 extend out of the cover plate 300 and are jointly fixed with a ring-shaped telescopic plate 600. Multiple springs are evenly connected between the bottom of the telescopic plate 600 and the top of the cover plate 300, and electromagnets 311 are fixed at corresponding positions respectively. The electromagnets 311 are electrically connected to a power supply and a switch.

[0028] When the bottom end of the central pipe 607 is connected to the wastewater conveying assembly, the filtered wastewater is transported along the central pipe 607 and the conveying connecting pipe 606 to the conveying ring pipe 605. During the wastewater treatment process, the outlet short pipe 604 is horizontally located in the pipe groove 401, with the inner end connected to the upper part of the through hole on the conveying ring pipe 605, and the outer end is located between the outer box body 200 and the inner box body 400, so that the water in the conveying ring pipe 605 is discharged outward along the outlet short pipe 604, enters between the outer box body 200 and the inner box body 400, and moves along the adsorption material, so as to transport and adsorb the transferred wastewater; When the equipment completes the wastewater treatment work, the electromagnets 311 on the bottom of the telescopic plate 600 and the top of the cover plate 300 are energized and attracted to each other, causing the telescopic plate 600 to compress the spring and drive the rack 601 to move downward, thereby causing the flip gear 602 to drive the rotating horizontal pipe 603 and the water outlet short pipe 604 to rotate, and the water outlet short pipe 604 rotates upward from the pipe groove 401 and continues to flip until the water outlet short pipe 604 is located at the outer side of the conveying ring pipe 605 and tilted toward the side wall of the inner box body 400, and the water outlet short pipe 604 is connected to the lower part of the through hole on the conveying ring pipe 605, so that after the cleaning water is conveyed into the inner box body 400, the cleaning water is repeatedly flushed toward the inner wall of the inner box body 400 through the action of the wastewater conveying component and the wastewater transfer component, thereby improving the cleaning effect of the side wall of the inner box body 400.

[0029] Among them, such as Figure 6 、 Figure 8As shown, the wastewater conveying assembly includes a fixed groove 500 located at the center of the circle in the middle of the inner box body 400, and the outer wall of the fixed groove 500 is fixed to the side wall of the inner box body 400 by a plurality of evenly arranged connecting frames 501. A water suction pump 503 is fixed above the center of the fixed groove 500 through a bracket, and a first water suction pipe 502 is fixed to the bottom of the water suction pump 503, and a second water suction pipe 504 is fixed to the top, and the top of the second water suction pipe 504 is inserted into the bottom end of the central pipe 607. The bottom end of the first water suction pipe 502 is close to the bottom of the inner box body 400, and a recovery filter tank 510 with an opening facing downward is fixed to the outer side of the lower part. The bottom end of the recovery filter tank 510 is in contact with the bottom surface of the inner box body 400, and filter holes are evenly distributed on the side walls.

[0030] When transporting and transferring wastewater, the wastewater is transported to the central pipe 607 of the wastewater transfer assembly through the water suction pump 503 and the first water suction pipe 502 and the second water suction pipe 504 so as to transfer the wastewater; after the wastewater is filtered once by the rotary filter assembly, it is filtered twice through the filter holes of the recovery filter tank 510 to improve the filtering effect and reduce the blockage of the water suction pump 503 and related pipelines.

[0031] Among them, such as Figure 7 As shown, the filter element assembly includes a cylindrical filter box 402 vertically fixed at the center of the bottom end of the inner box body 400, a drainage cylinder 406 is fixed at the center of the bottom end of the filter box 402, and a drainage pipe 407 is connected to one side of the bottom of the drainage cylinder 406. A partition 404 is fixed to the lower part of the inner cavity of the filter box 402, and a plurality of filter elements 405 are evenly fixed between the partition 404 and the top of the filter box 402. A through hole is provided on the partition 404 at the center of the bottom end of each filter element 405. A sealing plate 403 is fixed to the middle part of the outer wall of the filter box 402, and the side wall of the filter box 402 is evenly distributed with filter holes above the sealing plate 403. A vertical first sewage pipe 408 is fixed at the center of the partition 404, and the bottom end of the first sewage pipe 407 extends out of the filter box 402 and the drainage cylinder 406. A second sewage pipe 409 is provided at the bottom center of the inner box body 400, and is connected to the filter box 402 through the second sewage pipe 409, and valves are provided in the first sewage pipe 408 and the second sewage pipe 409.

[0032] After the wastewater has been filtered and treated with the adsorbent, it enters the filter box 402 along the filter holes on the upper side wall of the filter box 402, and while transporting the sewage through the filter holes, the adsorbent is prevented from entering the filter box 402; the wastewater entering the filter box 402 is filtered through multiple filter elements 405 to further improve the wastewater treatment and the filtering effect, and the treated wastewater is discharged through the drain cylinder 406 and the drain pipe 407 for subsequent recycling and discharge.

[0033] After the wastewater treatment is completed, the inner box body 400 and the filter element 405 are flushed, and the cleaning water in the inner box body 400 is discharged into the filter box 402 through the second sewage pipe 409, and the cleaning water in the filter box 402 is discharged through the second sewage pipe 409.

[0034] Example 2: The structure of this example is basically the same as that of Example 1, except that Figure 12 As shown, the stirring assembly includes a rotating vertical cylinder 505 rotatably connected to the outside of the first water suction pipe 502, and a plurality of stirring plates 509 are evenly provided on the outside of the rotating vertical cylinder 505.

Two fourth gears 507 are symmetrically engaged on both sides of the third gear 506, and the fourth gear 507 is rotatably connected to the bottom of the fixed groove 500. A third gear ring 508 is rotatably connected to the inner wall of the fixed groove 500, and the two fourth gears 507 are both engaged with the inner side of the third gear ring 508. A plurality of transmission holes are evenly provided on the third gear ring 508 along the circumferential direction, and are correspondingly connected to the transmission structure through the transmission holes.

[0035] When the rotary filter assembly rotates, the third gear ring 508 rotates through the connection between the transmission structure and the transmission hole, and the rotating vertical cylinder 505 drives the stirring plate to rotate through the transmission and speed regulation of the third gear 506 and the fourth gear 507, so that the wastewater and the treatment agent are fully mixed, and the impurities and water in the recovery filter tank 510 are stirred to prevent impurities from clogging the recovery filter tank 510.

[0036] like Figure 9 As shown, the rotary filter assembly includes a rotary filter cartridge 303 rotatably connected to the outer side of the bottom of the fixed cylinder 302. Filter holes are evenly distributed in the middle and lower part of the side wall of the rotary filter cartridge 303, and a second gear ring 307 is fixed to the upper part of the outer wall. A second gear 308 is meshed with one side of the second gear ring 307. The position of the second gear 308 is staggered with the position of the delivery connection pipe 606. The second gear 308 is connected to a motor, and the motor is fixedly connected to the bottom of the cover plate 300. The transmission structure includes multiple vertical transmission cylinders 304 evenly fixed to the bottom of the rotating filter cylinder 303 along the circumferential direction. Each transmission cylinder 304 is connected to a transmission shaft 305 through a spring, and the bottom end of the transmission shaft 305 extends out of the transmission cylinder 304 and extends into the transmission hole at the corresponding position on the third gear ring 508.

[0037] After the wastewater enters the rotating filter cartridge 303, the rotating filter cartridge 303 is rotated by the drive of the motor and the transmission of the second gear 308 and the second gear ring 307. The filtration speed is accelerated and the filtration effect is improved through the centrifugal effect of rotation. While the rotating filter cartridge 303 rotates, the third gear ring 508 is driven to rotate through the transmission cylinder 304 and the transmission shaft 305, thereby realizing the transmission of the rotating filter component and the stirring component.

[0038] During installation and connection, if the position of the transmission shaft 305 is misaligned with the position of the transmission hole, the transmission shaft 305 is squeezed by the third gear ring 508 and retracts into the transmission cylinder 304. When the rotating filter cylinder 303 drives the transmission shaft 305 and other structures to rotate, the transmission shaft 305 gradually moves into the transmission hole, and then extends out of the transmission cylinder 304 under the action of the spring, and extends into the transmission hole of the third gear ring 508, thereby realizing the connection between the rotating filter cylinder 303 and the third gear ring 508.

[0039] Example 3: The structure of this embodiment is basically the same as that of Example 2, except that Figure 6 、 Figure 9 As shown, a water retaining ring plate 306 is fixed to the bottom of the rotating filter cartridge 303, and the water retaining ring plate 306 is slidably connected to the upper part of the outer wall of the fixed groove 500. The position between the fixed groove 500 and the bottom of the rotating filter cartridge 303 is closed by the water retaining ring plate 306, which plays a water retaining role and prevents the water discharged from the rotating filter cartridge 303 from accidentally entering the fixed plate groove.

[0040] Example 4: The structure of this example is basically the same as that of Example 1, except that Figure 4 、 Figure 13 As shown, the lifting structure includes a fixed frame 101 symmetrically fixed at both ends of the top of the base 100, and two movable hydraulic rods 102 are symmetrically provided on the top of the fixed frame 101. The tops of the two movable hydraulic rods 102 are commonly fixed with a movable groove 103, and the openings of the movable grooves 103 on both sides are opposite to each other. A horizontal movable ring plate 201 is fixed in the middle of the outer wall of the outer box body 200, and movable protrusions 202 are symmetrically fixed at both ends of the movable ring plate 201. The movable protrusions 202 are slidably connected to the movable grooves 103 on the corresponding sides, and the bottom of the movable protrusion 202 is connected to the bottom of the inner cavity of the movable groove 103 through a spring.

[0041] When the outer box body 200 needs to be moved downward, the moving groove 103 is driven downward by moving the hydraulic rod 102, and under the action of gravity, the moving ring plate 201 and the moving protrusion 202 drive the outer box body 200 to move downward, so that the bottom end thereof is disengaged from the sealing plate 403 and opened, and the adsorbent filled inside is discharged for subsequent replacement operations, etc.; when the outer box body 200 moves back to its position, the outer box body 200 contacts the bottom of the cover plate 300, and the moving hydraulic rod 102 continues to move upward, so that the moving protrusion 202 continues to compress the spring until the spring can no longer be compressed, thereby making the relative positions of structures such as the moving groove 103 and the moving protrusion 202 stable, and keeping the top end of the outer box body 200 in stable contact with the cover plate 300.

[0042] like Figure 5 、 Figure 13 As shown, the vibration assembly includes an annular seat 104 fixed between the tops of two fixing frames 101. An annular cavity is provided inside the annular seat 104, and an annular spring plate 106 is provided on the upper part of the inner cavity of the annular cavity. The top of the spring plate 106 is connected to the top of the annular cavity through multiple springs, and multiple vertical spring shafts 105 are evenly fixed to the top of the spring plate 106 along the circumferential direction. The top ends of the spring shafts 105 extend out of the annular seat 104. A plurality of cams 107 are evenly arranged at the bottom of the spring plate 106 along the circumferential direction. The cams 107 are rotatably connected to the inner cavity side wall of the annular seat 104 and are coaxially fixed with a bevel gear 108. The interior of the annular seat 104 is rotatably connected to a rotating ring plate 110. A bevel gear ring 109 is fixed to the upper outer side of the rotating ring plate 110, and a first gear ring 111 is fixed to the lower outer side. Multiple bevel gears 108 are all engaged with the bevel gear ring 109, and a first gear 112 is engaged on one side of the first gear ring 111. The first gear 112 is rotatably connected to the annular seat 104, and a motor is connected to the bottom.

[0043] When the outer box body 200 moves downward, the bottom of the movable ring plate 201 contacts the top of the multiple spring shafts 105, and then under the drive of the motor, the transmission of the first gear 112 and the first ring gear 111, and the transmission of the bevel ring gear 109 and the multiple bevel gears 108, the multiple cams 107 rotate, so that the spring plate 106 drives the spring shaft 105 to move back and forth up and down, and cooperates with the spring in the movable groove 103, so that the movable ring plate 201 drives the outer box body 200 to vibrate up and down, thereby accelerating the discharge of the internal adsorbed material.

[0044] Example 5: The structure of this example is basically the same as that of Example 1, except that Figure 11As shown, a plurality of groups of buffer plates 205 are provided on the inner wall of the outer box body 200 at equal intervals in the height direction, and the side edges of the buffer plates 205 are in contact with the outer wall of the inner box body 400. Each group of buffer plates 205 includes a plurality of buffer plates, which are evenly arranged in the circumferential direction, and the positions of the buffer plates 205 of two adjacent groups in the height direction are staggered with each other, so that after the wastewater enters between the outer box body 200 and the inner box body 400, it flows to both sides along the top of each layer of buffer plates 205 in turn, and then falls to the top of the next group of buffer plates 205 and continues to flow to both sides, thereby increasing the movement path of the wastewater in the adsorbent, making it fully contact with the adsorbent, and improving the adsorption treatment effect.
