Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment in aluminum rod production, and in particular to a circulating treatment device for water used in aluminum rod production. Background Art

[0002] At present, the production process of aluminum profiles mainly includes degreasing, alkaline etching, pickling, oxidation, sealing and coloring of formed aluminum profiles. The profiles after the above processes need to be cleaned with water, and the cleaned water is aluminum production wastewater.

[0003] For example, a treatment liquid and treatment process for aluminum production wastewater provided by announcement number CN114853210B includes a treatment liquid comprising sulfuric acid, a calcium sulfite desulfurization slurry, sodium hydroxide, and a flocculant; the calcium sulfite desulfurization slurry comprises the following components: calcium oxide with unreacted calcium sulfite, and calcium hydroxide with unreacted calcium sulfite, wherein the calcium sulfite accounts for 30-60% by weight of the calcium sulfite desulfurization slurry. The treatment liquid can react and precipitate chromium, fluoride, and aluminum ions in the wastewater. The present invention also uses a regulating device, a reaction device, and a precipitation device to treat the aluminum production wastewater, thereby fully removing harmful substances in the aluminum wastewater.

[0004] Publication number CN118724161B provides wastewater recovery and treatment equipment for round aluminum rod production. It comprises a separation section for separating flocculants from wastewater, comprising a separation housing with a separation tube, the separation tube being tilted upward, and a drain pipe connected to the inner side of the middle portion of the separation tube; a stirring section; and an external discharge section comprising a first drainage housing for wastewater discharge and a second drainage housing for water discharge, the second drainage housing being connected to the drain pipe. In the separation tube, flocculants are distributed along the outer side of the separation tube, while clean water is distributed along the inner side of the separation tube. The clean water is discharged through the drain pipe, achieving efficient separation of flocculants from the wastewater and improving wastewater treatment efficiency. The separated wastewater can be used for cleaning and landscaping within the factory, reducing water waste.

[0005] However, when the above technology is actually used, since the aluminum rod production wastewater contains a large amount of aluminum chips and suspended matter, the above technology does not have a pretreatment device to filter out the aluminum chips and suspended matter, which affects the efficiency of subsequent sewage treatment. In addition, traditional fixed filter screens or filter element filtering devices are prone to clogging and cannot filter continuously.

[0040] 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.

[0041] See also Figure 1-11 The present invention provides a technical solution: a circulating treatment device for water used in aluminum rod production, comprising:

[0042] The housing assembly includes a filter tank 101, a solid collection frame 102, and a liquid collection hopper 103. The solid collection frame 102 is fixedly mounted on the bottom of the filter tank 101, and the liquid collection hopper 103 is fixedly mounted in the middle of the solid collection frame 102. The liquid collection hopper 103 is a funnel-shaped structure, and a liquid outlet pipe 104 is fixedly embedded in the bottom of the liquid collection hopper 103.

[0043] A stirring assembly is provided in the middle of the housing assembly, and includes a stirring shaft 201 and a stirring paddle 202 for generating centrifugal force on the liquid in the housing assembly. The top and bottom of the stirring shaft 201 are rotatably connected to the top of the filter tank 101 and the liquid collection hopper 103 respectively through brackets. The stirring paddle 202 is fixedly mounted on the surface of the stirring shaft 201, and the stirring shaft 201 is driven by a drive motor.

[0044] A centrifugal filter assembly is provided in the shell assembly, and the centrifugal filter assembly includes a separation tube 301 fixedly mounted on the top of the liquid collection bucket 103. The separation tube 301 is a regular polygonal structure, and a plurality of middle filter screens 302 are rotated in the middle of the side wall of the separation tube 301. A bottom filter screen 303 is fixedly mounted on the bottom of the inner wall of the separation tube 301, so that the solids in the wastewater adhere to the surface of the middle filter screen 302 corresponding to the center position of the shell assembly under the action of centrifugal force, and as the middle filter screen 302 rotates periodically, the solids are separated from the inside of the separation tube 301 and deposited in the solid collection frame 102, separating A through slot is formed in the side wall of the tube 301, and the middle filter screen 302 is located in the through slot. Support shafts 304 are fixedly mounted on the top and bottom of the middle filter screen 302, respectively. The support shafts 304 are rotatably connected to the inner wall of the through slot in the separator tube 301 via bearings. A first gear 305 is fixedly mounted on the top of the top support shaft 304. A gear ring 306 is meshed with the surface of the first gear 305. The cross section of the gear ring 306 is a C-shaped structure. The first gear 305 is located on the inner wall of the gear ring 306 to ensure that the first gear 305 and the gear ring 306 remain meshed and guide the rotation of the gear ring 306.

[0045] When the above structure is in use, the stirring shaft 201 drives the stirring paddle 202 to rotate, so that the solid waste is intercepted on the side of the middle filter 302 corresponding to the position of the stirring shaft 201 under the action of centrifugal force. Due to the existence of the bottom of the partition tube 301 and the solid collection frame 102, the end of the filter tank 101 corresponding to the bottom of the partition tube 301 and the solid collection frame 102 becomes a dead water area, that is, the liquid flow rate is not fast. When the middle filter 302 is flipped, this will cause the solid waste to settle on the solid collection frame 102. At the same time, the filtered liquid that passes through the bottom filter 303 will be discharged through the liquid collection bucket 103 and the liquid outlet pipe 104, so as to achieve the purpose of pre-filtration of the wastewater.

[0046] A self-cleaning assembly is provided on the surface of the separation tube 301, and the self-cleaning assembly includes a rotating sleeve 411 provided on the surface of the middle filter screen 302 away from the center position of the shell assembly, and the rotating sleeve 411 moves up and down along the direction of the middle filter screen 302 while rotating and moving laterally. A brush 412 is fixedly installed on the surface of the rotating sleeve 411, so that the brush 412 periodically cleans the solids on the surface of the middle filter screen 302 away from the center position of the shell assembly. The self-cleaning assembly also includes a fixed ring 401 fixedly installed on the top of the inner wall of the filter tank 101, and the bottom of the fixed ring 401 is hinged with an articulated hydraulic cylinder 307, and the articulated hydraulic cylinder 307 is hinged to the top of the gear ring 306, so that when the articulated hydraulic cylinder 307 contracts and expands, it drives the gear ring 306 to rotate back and forth, thereby driving the middle filter screen 302 to rotate in the through groove in the separation tube 301 and change the direction of rotation through the gear ring 306 in cooperation with the first gear 305 and the support shaft 304;

[0047] When the above structure is in use, the articulated hydraulic cylinder 307 drives the gear ring 306 to rotate, and the gear ring 306 drives the first gear 305 to rotate 180°, which will cause the first gear 305 to cooperate with the support shaft 304 to drive the middle filter screen 302 to rotate 180°, and make the side of the middle filter screen 302 covered with solid waste away from the stirring shaft 201, and the clean side of the middle filter screen 302 face the stirring shaft 201, thereby achieving the purpose of continuous filtration.

[0048] A plurality of driving columns 402 are fixedly installed between the fixing ring 401 and the solid collection frame 102. A second gear 404 is rotatably provided on the surface of the driving column 402. A gear rod 408 is meshed with the surface of the second gear 404. A driving rod 409 is fixedly installed on the end of the gear rod 408 away from the second gear 404. The driving rod 409 is rotatably connected to the inner wall of the rotating sleeve 411, so that when the second gear 404 rotates, the gear rod 408 cooperates with the driving rod 409 to drive the rotating sleeve 411 and the brush 412 to move. An annular groove is provided on the surface of the driving rod 409, and an annular ridge is provided on the inner wall of the rotating sleeve 411, so that the rotating sleeve 411 and the driving rod 409 can maintain relative rotation. 411 and the driving rod 409 remain relatively stationary in the axial direction, and the two adjacent gear rods 408 are staggered up and down. The surface of the driving column 402 is movably sleeved with a first sleeve 405, and the second gear 404 is rotatably connected to the surface of the first sleeve 405 through a bearing. A driving groove 406 is opened on the surface of the driving column 402, and a notch 1 is opened in the middle of the first sleeve 405 corresponding to the driving groove 406. A driving head 407 is fixedly installed on the inner wall of the second gear 404 corresponding to the notch 1. The driving head 407 is movably connected to the inner wall of the driving groove 406, so that when the second gear 404 moves up and down, the driving head 407 cooperates with the driving groove 406 to drive the second gear 404 to rotate back and forth;

[0049] When the above structure is in use, when the first sleeve 405 moves up and down on the surface of the driving column 402, the second gear 404 will drive the second gear 404 to move up and down. By setting the driving head 407 and the driving groove 406, and the notch in the middle of the first sleeve 405, the driving head 407 will move along the inner wall of the driving groove 406 as the second gear 404 moves up and down, thereby driving the second gear 404 to rotate back and forth, that is, the second gear 404 will swing back and forth under the action of the driving groove 406 and the driving head 407 when moving up and down, and when the second gear 404 swings back and forth, the second gear 404 will drive the gear rod 408 to move back and forth, and the gear rod 408 will drive the rotating sleeve 411 and the brush 412 to move axially back and forth through the driving rod 409.

[0050] A plurality of first gear posts 403 are fixedly installed between the fixing ring 401 and the solid collection frame 102. The driving post 402 and the first gear posts 403 are respectively located at the corners of the separation tube 301. The surface of the first gear post 403 is movably sleeved with a second sleeve 414. The top and bottom of the second sleeve 414 are respectively fixedly installed with a first connecting frame 413. A second gear post 415 is rotatably connected between the two first connecting frames 413 through a bearing. A notch 2 is opened in the middle of the second sleeve 414 corresponding to the position of the second gear post 415. The surface of the second tooth column 415 meshes with the surface of the first tooth column 403 through the notch 2. A third gear 416 is fixedly mounted on both ends of the second tooth column 415. The surface of the third gear 416 meshes with the drive tube 410. The drive tube 410 is movably sleeved on the surface of one end of the drive rod 409 and the drive tube 410 is movably sleeved on the inner wall of the rotating sleeve 411. The surface of the drive tube 410 and the inner wall of the rotating sleeve 411 are both regular polygonal structures, so that the drive tube 410 drives the rotating sleeve 411 to rotate.

[0051] When the above structure is in use, when the second sleeve 414 moves up and down on the surface of the first tooth column 403, the second sleeve 414 drives the first connecting frame 413 to move vertically up and down, and the second tooth column 415 is engaged with the first tooth column 403 through the notch 2 on the surface of the second sleeve 414, so that when the second sleeve 414 moves up and down, the second tooth column 415 is driven to rotate, and when the second tooth column 415 rotates, the second tooth column 415 drives the driving tube 410 to rotate through the third gear 416, wherein the driving tube 410 is movable. The movable sleeve is connected to the surface of the driving rod 409 and the inner wall of the rotating sleeve 411, but the surface of the driving tube 410 and the inner wall of the rotating sleeve 411 are both regular polygonal structures. This makes the rotating sleeve 411 rotate accordingly when the driving tube 410 rotates, but the driving tube 410 does not affect the axial reciprocating movement of the rotating sleeve 411. Therefore, when the second sleeve 414 moves up and down, the second gear column 415 cooperates with the first gear column 403, the third gear 416 and the driving tube 410 to drive the rotating sleeve 411 and the brush 412 to rotate.

[0052] The top and bottom of the first sleeve 405 are respectively fixedly mounted with a second connecting frame 417, and the end of the second connecting frame 417 away from the first sleeve 405 is fixedly mounted with a guide frame 418, and the guide frame 418 is rotatably connected to the inner wall of the driving tube 410 through a bearing, and the two adjacent guide frames 418 and the gear rod 408 are arranged in parallel, and a guide groove 419 is provided at the end of the gear rod 408 away from the second gear 404, and a guide protrusion 420 is fixedly mounted on the end of the guide frame 418 corresponding to the guide groove 419, and the guide protrusion 420 is movably connected to the inner wall of the guide groove 419, and the inner wall of the guide frame 418 away from the gear rod 408 is rotatably connected to the third connecting frame 421 through a bearing. 21 and the first connecting frame 413 are all fixedly mounted on one end of the guide frame 418, and a protective cover 423 is fixedly mounted on the surfaces of the second connecting frame 417, the guide frame 418, the first connecting frame 413 and the third connecting frame 421, and the gear rod 408 and the second gear column 415 movably pass through the protective cover 423, so that the protective cover 423 protects the second gear 404 and the second gear column 415, and a driving ring 422 is fixedly mounted on one end of the protective cover 423. A chain conveying assembly 5 is fixedly provided at one end of the filter tank 101. The chain conveying assembly 5 includes a chain, and the chain passes through the filter tank 101 and is fixedly mounted on the surface of the driving ring 422, so that the chain conveying assembly 5 drives the driving ring 422 to move up and down through the chain when working;

[0053] When the above structure is in use, by providing the guide groove 419 and the guide protrusion 420, the guide groove 419 cooperates with the guide protrusion 420 to guide the movement of the gear rod 408, so that the gear rod 408 and the driving rod 409 can move stably. At the same time, the guide frame 418 cooperates with the third connecting frame 421 and the bearing to support the driving tube 410, and the driving tube 410 is movably connected to the surface of the driving rod 409 and the inner wall of the rotating sleeve 411, so that the driving tube 410 supports the driving rod 409 and the rotating sleeve 411. At the same time, due to the annular groove provided on the surface of the driving rod 409 and the annular ridge provided on the inner wall of the rotating sleeve 411, the rotating sleeve 411 and the driving rod 409 can rotate relative to each other, but remain relatively stationary during axial movement, so that the rotating sleeve 411 and the brush 412 can rotate stably on the surface of the driving rod 409.

[0054] Working principle: When in use, the invention drives the stirring shaft 201 to rotate through the driving motor, and the stirring shaft 201 drives the stirring paddle 202 to rotate, so that the liquid inside the shell assembly circulates and, under the action of centrifugal force, solid waste, such as aluminum chips and suspended solids, are intercepted on the side of the middle filter screen 302 corresponding to the position of the stirring shaft 201. Due to the existence of the bottom of the partition tube 301 and the solid collection frame 102, the end of the filter tank 101 corresponding to the bottom of the partition tube 301 and the solid collection frame 102 becomes a dead water area, that is, the liquid flow rate is not fast. When When the middle filter screen 302 is turned over, solid waste will be deposited on the solid collection frame 102. At the same time, the filtered liquid that passes through the bottom filter screen 303 will be discharged through the liquid collection bucket 103 and the liquid outlet pipe 104, so as to achieve the purpose of pre-filtering the wastewater. Since the stirring shaft 201 keeps driving the stirring paddle 202 to rotate, and the device is suitable for a filtering device with continuous water inflow, the bottom filter screen 303 will intercept solids but it is difficult for solids to be precipitated on the bottom filter screen 303. That is, the bottom filter screen 303 will not be blocked after continuous use.

[0055] When the middle filter screen 302 is covered with solid waste, the articulated hydraulic cylinder 307 drives the gear ring 306 to rotate, and the gear ring 306 drives the first gear 305 to rotate 180 degrees. This causes the first gear 305 to cooperate with the support shaft 304 to drive the middle filter screen 302 to rotate 180 degrees, so that the side of the middle filter screen 302 covered with solid waste is away from the stirring shaft 201, and the clean side of the middle filter screen 302 is facing the stirring shaft 201, thereby achieving the purpose of continuous filtration.

[0056] When the side of the middle filter screen 302 covered with solid waste is away from the stirring shaft 201, the chain conveyor assembly 5 starts to work and drives the driving ring 422 to move up and down. When the driving ring 422 moves, the driving ring 422 cooperates with the second connecting frame 417, the guide frame 418, the first connecting frame 413 and the third connecting frame 421 through the protective cover 423 to drive the first sleeve 405, the second sleeve 414 and the driving pipe 410 to move up and down.

[0057] When the first sleeve 405 moves up and down on the surface of the driving column 402, the second gear 404 drives the second gear 404 to move up and down. By providing the driving head 407 and the driving groove 406, as well as the notch in the middle of the first sleeve 405, the driving head 407 moves along the inner wall of the driving groove 406 as the second gear 404 moves up and down, thereby driving the second gear 404 to rotate back and forth. That is, when the second gear 404 moves up and down, the driving groove 406 cooperates with the driving head 407 to swing back and forth. When the second gear 404 swings back and forth, the second gear 404 drives the gear rod 408 to move back and forth, and the gear rod 408 drives the rotating sleeve 411 and the brush 412 to move back and forth axially through the driving rod 409.

[0058] When the second sleeve 414 moves up and down on the surface of the first tooth column 403, the second sleeve 414 drives the first connecting frame 413 to move up and down vertically, and the second tooth column 415 is engaged with the first tooth column 403 through the notch 2 on the surface of the second sleeve 414, so that the second sleeve 414 moves up and down, which drives the second tooth column 415 to rotate. When the second tooth column 415 rotates, the second tooth column 415 drives the driving tube 410 to rotate through the third gear 416. On the surface of the driving rod 409 and the inner wall of the rotating sleeve 411, the surface of the driving tube 410 and the inner wall of the rotating sleeve 411 are both regular polygonal structures. This makes it possible for the rotating sleeve 411 to rotate when the driving tube 410 rotates, but the driving tube 410 does not affect the axial reciprocating movement of the rotating sleeve 411. Therefore, when the second sleeve 414 moves up and down, the second gear column 415 cooperates with the first gear column 403, the third gear 416 and the driving tube 410 to drive the rotating sleeve 411 and the brush 412 to rotate;

[0059] When the driving tube 410 moves up and down, the driving tube 410 drives the driving rod 409, the rotating sleeve 411 and the brush 412 to move up and down;

[0060] Integrating the movement process of the rotating sleeve 411 and the brush 412, it can be seen that the rotating sleeve 411 and the brush 412 rotate and reciprocate axially while moving vertically up and down, so that the movement, rotation and axial reciprocation of the brush 412 can effectively remove solid waste on the surface of the middle filter screen 302 and settle on the inner wall of the filter tank 101 to the dead water area at the bottom of the filter tank 101;

[0061] By providing the guide groove 419 and the guide protrusion 420, the guide groove 419 cooperates with the guide protrusion 420 to guide the movement of the gear rod 408, so that the gear rod 408 and the driving rod 409 can move stably. At the same time, the guide frame 418 cooperates with the third connecting frame 421 and the bearing to support the driving tube 410, and the driving tube 410 is movably sleeved on the surface of the driving rod 409 and the inner wall of the rotating sleeve 411, so that the driving tube 410 supports the driving rod 409 and the rotating sleeve 411. At the same time, due to the annular groove provided on the surface of the driving rod 409 and the annular ridge provided on the inner wall of the rotating sleeve 411, the rotating sleeve 411 and the driving rod 409 can rotate relative to each other, but remain relatively stationary during axial movement, so that the rotating sleeve 411 and the brush 412 can rotate stably on the surface of the driving rod 409;

[0062] The wastewater is stirred by the stirring assembly so that the solid waste adheres to the surface of the middle filter screen 302 under the action of centrifugal force. Then the middle filter screen 302 rotates, and the side of the middle filter screen 302 covered with solid waste is away from the stirring shaft 201, and the clean side of the middle filter screen 302 faces the stirring shaft 201. Then, the rotating sleeve 411 drives the brush 412 to move, rotate and axially reciprocate on the surface of the middle filter screen 302, effectively removing the solid waste on the surface of the middle filter screen 302, and achieving continuous filtration.
