Detailed implementation manners

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0050] Embodiment 1. Referring to the accompanying drawings, the present invention provides a technical solution:

[0051] A cleaning water recovery mechanism for the recycling of automobile sheet metal parts, as Figure 1 、 Figure 2 shown, includes a water collecting tank 100, a tank cover 200 and a box body 300 fixed in sequence from top to bottom. A vertical water inlet pipe 103 is fixed in the middle of the bottom of the water collecting tank 100, and the bottom end of the water inlet pipe 103 extends into the interior of the tank cover 200;

[0052] As Figure 5 shown, a plurality of hydraulic telescopic rods 203 are evenly arranged on the tank cover 200 along the circumferential direction, and the bottom ends of the plurality of hydraulic telescopic rods 203 extend into the tank cover 200 and are commonly connected to a multi-stage filtering assembly;

[0053] As Figure 2 、 Figure 3 shown, an intermediate tank 400 is fixed between the tank cover 200 and the box body 300. A fixed ring platform 401 is arranged inside the intermediate tank 400, and the outer region of the fixed ring platform 401 is set as a waste material tank 402, and the inner region is set as a driving tank 403. A vertical central cylinder 404 is fixed at the center of the driving tank 403. A sliding cylinder 501 is slidably connected in the central cylinder 404. The top end of the sliding cylinder 501 extends out of the central cylinder 404 and is fixed with a bearing plate 500. The top of the bearing plate 500 contacts the bottom end of the multi-stage filtering assembly, and the bottom is connected with a rotating assembly and a vibration structure;

[0054] As Figure 7 shown, a plurality of shunt pipes 405 are evenly arranged on the bottom of the side wall of the central cylinder 404 along the circumferential direction, and a sealing assembly is rotatably connected at the position corresponding to the shunt pipes 405 at the bottom of the inner cavity of the central cylinder 404;

[0055] As Figure 2 shown, a plurality of stirring assemblies are evenly arranged on the bottom of the intermediate tank 400 along the circumferential direction. One end of the shunt pipe 405 is connected to the top of the stirring assembly, and the top ends of the plurality of stirring assemblies are commonly connected to a driving assembly;

[0056] As Figure 3 、 Figure 13As shown, a water collecting cylinder 306 is provided at the center of the bottom of the box body 300, and a sewage pipe 302 and a valve are provided on one side of the bottom. A drain pipe 302 and a drain pump 303 are connected to the bottom of the water collecting cylinder 306, and a reuse pipe 304 is connected to the top of the outer section of the drain pipe 302.

[0057] When the sheet metal parts are being cleaned, the cleaning structure is arranged above the water collecting tank 100, so that the waste water after cleaning directly falls into the water collecting tank 100, and is sent into the box body 300 through the water inlet pipe 103, enters the multi-stage filtration assembly, and undergoes multi-stage filtration treatment to remove most of the solid impurities or waste materials in the cleaning water.

[0058] The cleaned water after filtration flows into the sliding cylinder 501 along the top of the material bearing plate 500, and then enters the central cylinder 404. Among the multiple shunt pipes 405 connected to the central cylinder 404, one is communicated with the inner cavity of the central cylinder 404, and the rest are closed by the sealing assembly, so that the cleaning water enters one of the stirring assemblies along the corresponding shunt pipe 405, and a treatment agent is added. Then, the driving assembly is used to make the stirring assembly move to stir and mix the cleaning water and the treatment agent.

[0059] When a certain amount of cleaning water is input into one of the stirring assemblies, the sealing assembly rotates to open the shunt pipe 405 at the next adjacent position, and the rest of the shunt pipes 405 are closed, so as to convey the cleaning water to the adjacent stirring assembly, and through the intermittent rotation of the sealing assembly, the multiple shunt pipes 405 are sequentially opened, and water is alternately fed into the multiple stirring assemblies;

[0060] After one of the stirring assemblies is filled with water, during the process that the sealing assembly rotates intermittently for one week, enough time is left to fully mix the treatment agent and the cleaning water to ensure the mixing treatment effect, and before the sealing assembly returns to the position of this stirring assembly, the mixed cleaning water is discharged and re-sealed, so that when the sealing assembly returns to this position, water inlet and stirring work can continue.

[0061] The multiple stirring assemblies sequentially discharge the mixed water, so as to alternately drain water to the bottom of the box body 300, and the cleaning water is filtered again through the filter membrane structure 305 to improve the filtration effect and the quality of the treated cleaning water, and then is transported out through the drain pump 303 and the drain pipe 302 for subsequent recycling treatment, or the cleaning water can be recycled through the reuse pipe 304 and used again for cleaning the sheet metal parts.

[0062] After the washing water recycling process is completed, a large amount of solid waste or impurities are accumulated on the top of the receiving plate 500. The multi-stage filter assembly is moved upward by the hydraulic telescopic rod 203, so that the bottom end thereof is separated from the receiving plate 500, and the filtered impurities fall onto the receiving plate 500, so as to clean the multi-stage filter assembly. The receiving plate 500 is vibrated while rotating by the rotating assembly and the vibration structure, so that the waste on the receiving plate 500 can be quickly moved outward and collected in the waste tank 402.

[0063] When waste is collected in the waste tank 402 for many times and a large amount of waste is accumulated, the box cover 200 and other structures can be disassembled, the middle tank 400 can be opened, and the waste can be cleaned.

[0064] Among them, Figure 5 As shown, the multi-stage filtering assembly includes a guide plate 201 located in the box cover 200, and a vertical water retaining ring plate 202 is arranged around the outer side of the guide plate 201, and the top of the water retaining ring plate 202 is connected to the bottom end of multiple hydraulic telescopic rods 203, and multiple connecting shafts 207 are evenly fixed to the outer side of the bottom of the guide plate 201 along the circumferential direction, and are fixed to the inner side wall of the water retaining ring plate 202 through the connecting shafts 207, and multiple annular filter plates 204 are evenly and concentrically fixed to the bottom of the guide plate 201, and filter holes are evenly distributed on the side walls of the annular filter plates 204, and the filter holes on the multiple annular filter plates 204 decrease successively from the outside to the inside.

[0065] When the multi-stage filtering assembly is working, the bottom ends of the water retaining ring plate 202 and the plurality of annular filter plates 204 contact the top end of the material receiving plate 500, so that the bottom ends of the water retaining ring plate 202 and the annular filter plate 204 are closed, so that the cleaning water transported by the water inlet pipe 103 flows outward along the guide plate 201, falls to the inner position of the water retaining ring plate 202, and flows from outside to inside, and passes through the filtering treatment of the plurality of annular filter plates 204 in sequence, thereby realizing multi-stage filtration; when it is necessary to clean the waste impurities at the annular filter plate 204, the water collection tank 100 and the water inlet pipe 103 stop feeding, and then the hydraulic telescopic rod 203 drives the water retaining ring plate 202, the guide plate 201 and the plurality of annular filter plates 204 to move upward, so that the bottom ends thereof are separated from the material receiving plate 500, and the waste materials are located on the material receiving plate 500, and the material receiving plate 500 is vibrated while rotating by the rotating assembly and the vibration structure, so that the impurities and waste materials are cleaned and discharged.

[0066] Among them, Figure 8As shown in the figure, the rotating assembly includes an annular support frame 503 fixed in the driving groove 403. A rotating cylinder 506 is rotatably connected in the support frame 503. A transmission gear ring 505 is fixed on the rotating cylinder 506. A driving gear 504 is engaged with one side of the transmission gear ring 505. The driving gear 504 is connected to a motor, and the motor is fixed to the support frame 503. A plurality of vertical limiting grooves are uniformly arranged on the inner side wall of the rotating cylinder 506 along the circumferential direction. A sliding cylinder 501 is slidably connected in the rotating cylinder 506, and a plurality of vertical limiting strips 502 are correspondingly fixed on the outer side wall. The limiting strips 502 are slidably connected in the corresponding limiting grooves.

[0067] When it is necessary to rotate the material receiving plate 500, through the drive of the motor and the transmission of the driving gear 504 and the transmission gear ring 505, the rotating cylinder 506 is rotated, and through the relative limiting action of the limiting groove and the limiting strip 502, the sliding cylinder 501 and the material receiving plate 500 are driven to rotate, so that with the cooperation of the vibration structure, the waste on the top of the material receiving plate 500 moves towards the waste groove 402, playing a cleaning role; the sliding cylinder 501 and the limiting strip 502 can slide relative to the rotating cylinder 506, so as to cooperate with the movement of the vibration structure, and in the case of relative sliding between the rotating cylinder 506 and the sliding cylinder 501, through the action of the limiting groove and the limiting strip 502, the rotation of the material receiving plate 500 can still be ensured.

[0068] Among them, as Figure 9 , Figure 10 shown in the figure, the vibration structure includes a rotating ring plate 408 rotatably connected to the inner side wall of the fixed ring platform 401. The top of the rotating ring plate 408 is connected to the bottom of the material receiving plate 500 through a plurality of uniformly arranged springs. A plurality of vertical spring shafts 507 are slidably connected to the rotating ring plate 408, and the top ends of the spring shafts 507 are fixedly connected to the bottom of the material receiving plate 500. A plurality of semi-circular convex blocks 409 are uniformly fixed on the top of the fixed ring platform 401 along the circumferential direction. A plurality of top wheels 509 are uniformly arranged and rotatably connected to the bottom of the material receiving plate 500 along the circumferential direction, and the top wheels 509 are in contact with the top of the fixed ring platform 401 and the convex blocks 409 correspondingly. An outer ring plate 508 is fixedly fixed to the outer side of the bottom end of the material receiving plate 500. The outer ring plate 508 is slidably connected to the outer side wall of the fixed ring platform 401. The outer ring plate 508 and the fixed ring platform 401 provide a certain water-blocking effect for the structure inside the driving groove 403.

[0069] During the rotation of the material receiving plate 500, through the intermittent contact between the top wheels 509 and the convex blocks 409, the material receiving plate 500 can vibrate up and down. Among them, the rotating ring plate 408 rotates with the material receiving plate 500 under the action of the spring shafts 507, so that the spring can move accordingly, enabling the spring to only expand and contract in the vertical direction and cooperate with the top wheels 509 and the convex blocks 409 to realize the up and down vibration of the material receiving plate 500, so as to accelerate the discharge of the waste on the material receiving plate 500.

[0070] Among them, as Figure 7 shown, the sealing component includes a cylindrical rotating sealing seat 406 rotatably connected to the bottom of the inner cavity of the central cylinder 404. The circumferential side wall of the rotating sealing seat 406 contacts the inner side wall of the central cylinder 404. A sealing gasket can be arranged on the side wall of the rotating sealing seat 406 to improve the sealing performance between the side wall of the central cylinder 404. The bottom center of the rotating sealing seat 406 is connected with a motor, and a diversion groove 407 is arranged on one side of the upper part. One end of the diversion groove 407 extends to the side wall of the rotating sealing seat 406 and communicates with the corresponding shunt pipe 405 at the corresponding position.

[0071] When it is necessary to open one of the shunt pipes 405, the rotating sealing seat 406 is driven to rotate by the motor, so that the diversion groove 407 communicates with the corresponding shunt pipe 405, so that the cleaning water can enter the central cylinder 404 and enter the stirring component connected thereto along the corresponding shunt pipe 405; among them, the rotating sealing seat 406 rotates intermittently under the control of the motor, so as to intermittently and sequentially move to each shunt pipe 405, so as to sequentially convey the cleaning water to multiple stirring components, and during the process of the rotating sealing seat 406 rotating one week, the stirring component at the corresponding position can have enough time to perform sufficient stirring and discharge the cleaning water, so as to perform the next water inlet and stirring mixing operation.

[0072] Embodiment 2. The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that, as Figure 11 shown, the stirring component includes a fixing frame 600 fixed to the bottom of the middle tank 400. As Figure 12 shown, an annular frame 612 is fixed on the fixing frame 600. A stirring cylinder 602 is installed in the annular frame 612. A drain port 604 and a valve are arranged at the bottom of the stirring cylinder 602. A cover plate 603 is arranged at the top of the stirring cylinder 602. As Figure 4 shown, the end parts of the shunt pipes 405 respectively pass through the corresponding cover plates 603 and extend into the inner cavity of the stirring cylinder 602. A vertical stirring shaft 605 is rotatably connected to the center of the cover plate 603. The top end of the stirring shaft 605 is correspondingly connected to the driving component. The middle and lower parts of the stirring shaft 605 are located in the stirring cylinder 602, and a plurality of stirring blades are uniformly arranged along the circumferential direction.

[0073] As Figure 11 shown, the fixing frames 600 in a plurality of stirring components are uniformly arranged along the circumferential direction, and a support plate 601 is commonly fixed to the inner ends of the plurality of fixing frames 600. A feeding pump 609 is arranged at the bottom of the support plate 601. One side of the feeding pump 609 is connected with a feeding pipe 611, and one end of the feeding pipe 611 passes through the side wall of the box body 300 and extends out. A plurality of feeding pipes 610 are uniformly connected to the feeding pump 609 along the circumferential direction, and one end of the feeding pipe 610 is communicated and fixed with the stirring cylinder 602 at the corresponding position.

[0074] When the cleaning wastewater enters the corresponding mixing drum 602 through the diversion pipe 405, when passing through the feeding pump 609 and the feeding pipe 611, the treatment agent and the like enter the mixing drum 602 along the feeding pipe 611. The driving assembly drives the stirring shaft 605 and the stirring blades to rotate, so as to perform stirring and mixing treatment on the cleaning water and the treatment agent. After stirring for a certain period of time, the drain port 604 is opened to discharge the cleaning water from the mixing drum 602, so as to perform secondary filtration treatment through the filter membrane structure 305.

[0075] Example 3. The structure of this example is basically the same as that of Example 2, except that, as Figure 7 shown, the driving assembly includes a first gear ring 607 rotatably connected to the bottom of the driving groove 403. A second gear 608 is engaged with one side of the first gear ring 607. The second gear 608 is connected to a motor, and the motor is fixed to the bottom of the driving groove 403. The tops of multiple stirring shafts 605 pass through the bottom of the middle groove 400, extend into the driving groove 403, and are fixed with first gears 606. Multiple first gears 606 are all engaged with the first gear ring 607, and the positions of the first gears 606 and the second gear 608 are staggered. Through the drive of the motor and the transmission of the second gear 608 and the first gear ring 607, multiple first gears 606 rotate simultaneously, and then drive the stirring shaft 605 and the stirring blades to rotate, so as to mix and stir the cleaning wastewater and the treatment agent in the mixing drum 602.

[0076] Example 4. The structure of this example is basically the same as that of Example 1, except that, as Figure 6 shown, a plurality of spring cylinders 205 are uniformly fixed on the top of the water retaining ring plate 202 along the circumferential direction. The bottom end of the hydraulic expansion rod 203 extends into the spring cylinder 205 and is fixed with a spring block 206, and the bottom of the spring block 206 and the top of the water retaining ring plate 202 are connected by a spring. Through the action of the spring, the bottom ends of the water retaining ring plate 202 and multiple annular filter plates 204 are tightly pressed on the material bearing plate 500, so that the bottom ends of the annular filter plates 204 are closed, so that the cleaning water can be filtered in multiple stages and conveyed downward through the sliding cylinder 501; when the material bearing plate 500 rotates, it vibrates up and down under the action of the vibration structure, and at the same time, through the action of the spring block 206 and the spring, multiple annular filter plates 204 and other structures vibrate accordingly, so that the waste impurities and the like accumulated at the annular filter plates 204 can fall onto the material bearing plate 500, improving the cleaning effect of the annular filter plates 204.

[0077] Example 5. The structure of this example is basically the same as that of Example 1, except that, as Figure 3As shown in the figure, an arc-shaped net plate 101 is fixed in the middle of the upper part of the water collecting tank 100, and collecting plates 102 are fixed between both ends of the arc-shaped net plate 101 and the side walls of the water collecting tank 100. When collecting the cleaning wastewater through the water collecting tank 100, the arc-shaped net plate 101 intercepts the falling parts and larger waste materials, and moves along the arc surface of the arc-shaped net plate 101 to the collecting plates 102 on both sides, so that the part waste materials are concentrated at the collecting plates 102, which is convenient for subsequent cleaning and collection.

[0078] As Figure 3 As shown in the figure, an annular pipe boss 104 is fixed on the outer side wall of the water inlet pipe 103, and the top of the pipe boss 104 is in contact with the top of the box cover 200. When installing the water collecting tank 100 and the water inlet pipe 103, the height position of the water inlet pipe 103 relative to the box cover 200 can be quickly determined through the pipe boss 104.
