Description

Technical Field

[0001] The invention relates to the field of metal recycling, and in particular to a multifunctional recycling device for scrap metal. Background Art

[0002] During the building demolition process, a large number of steel bars with hard concrete residues are often generated. These concrete residues are tightly attached to the surface of the steel bars, making it difficult to directly recycle the steel bars. Therefore, before the steel bars can be effectively reused, these hard concrete fragments must be completely removed from the steel bars through professional crushing and stripping processes. This process not only ensures the quality of the steel bars, but also provides a guarantee for the recycling of resources. A Chinese patent with publication number CN118558448A discloses a construction waste recycling device, which uses two impact plates to swing and impact the surface of metal construction waste to separate the solidified concrete on the surface of the metal construction waste. However, this treatment method is difficult to completely remove the concrete fragments on the steel bars, so the workers have to manually scrape off the remaining concrete. This process not only greatly increases the labor intensity of the workers, but also has low efficiency. Even after the scraping treatment, a thin layer of concrete will still remain on the surface of the steel bars, which has a negative impact on the quality of the steel bars and subsequent recycling. This situation not only reduces the overall quality of the recycled materials, but may also increase the cost and complexity of subsequent processing. Summary of the invention

[0019] It also includes an electric push rod II 101 and an interception frame 102; the rotating frame 2 is fixedly connected to two electric push rods II 101; the telescopic ends of all the electric push rods II 101 are commonly fixedly connected to the interception frame 102, and the interception frame 102 is slidably connected to the rotating frame 2, and the steel bars are intercepted by the interception frame 102.

[0020] It also includes an electric push rod III 201 and a baffle 202; the rotating frame 2 is fixedly connected to two electric push rods III 201; the telescopic ends of all the electric push rods III 201 are commonly fixedly connected to the baffle 202, and the baffle 202 is slidably connected to the rotating frame 2, and the concrete fragments are blocked by the baffle 202.

[0021] It also includes a water spray bar 203; the rotating frame 2 is fixedly connected to the water spray bar 203, and the water spray bar 203 is located above the feed port 2001, and the water spray bar 203 is inclined to the lower right, and the water spray bar 203 is provided with a plurality of water spray ports, and the water spray bar 203 is connected to an external water pump, and water mist is sprayed out of the feed port 2001 through the water spray bar 203 to perform dust reduction treatment.

[0022] It also includes dustproof strips Ⅰ204 and sliding plates 205. The push plate 4 is fixed with four dustproof strips Ⅰ204, and the dustproof strips Ⅰ204 are located in the avoidance groove of the rotating frame 2, and the dustproof strips Ⅰ204 are in contact with the avoidance groove. Each electric push rod Ⅰ6 passes through a dustproof strip Ⅰ204 located below; the extrusion plate Ⅰ5 is slidably connected to two sliding plates 205 through a spring telescopic rod, and the sliding plate 205 is in contact with the inner wall of the rotating frame 2.

[0023] The working steps of the above embodiment are: first, the staff pours the steel bars with concrete fragments adhered to them into the feed port 2001, so that they enter the rotating frame 2. When the steel bars with concrete fragments adhered to them are poured in, the hydraulic push rod 3 is controlled to push the push plate 4 to move up and down repeatedly, and the push plate 4 drives the extrusion plate Ⅰ5 and all the parts connected to it to move up and down repeatedly. When the crushing plates 7 arranged above and below come into contact with the steel-reinforced concrete fragments, the crushing plates 7 will squeeze and crush the steel-reinforced concrete fragments, thereby crushing the concrete fragments adhered to the steel bars and reducing the amount of concrete adhered to the steel bars; During the concrete crushing process, the extrusion plate Ⅰ5 is pushed to move in the front-to-back direction by controlling the electric push rod Ⅰ6, driving the crushing plate 7 on the extrusion plate Ⅰ5 to move back and forth, thereby adjusting the position of the crushing plate 7 on the extrusion plate Ⅰ5, and then cooperating with the crushing plate 7 below to crush the concrete that the original crushing plate 7 could not touch, to avoid the large gap between the crushing plate 7 on the extrusion plate Ⅰ5 and the crushing plate 7 on the rotating frame 2 in the front-to-back direction, so that the crushing plate 7 cannot crush the concrete fragments in the gap position, resulting in large concrete fragments still existing on the steel bars after the crushing work is completed.

[0024] It should be noted that, in the process of crushing concrete fragments, a large amount of smoke and dust will be generated, and in the initial state, the baffle plate 202 is respectively fitted with the left side of the extrusion plate Ⅰ5, the inner side surface of the rotating frame 2 and the inner bottom surface of the rotating frame 2, so the smoke and dust cannot float out from the left side of the extrusion plate Ⅰ5, so that the smoke and dust can only float out from the feed port 2001, and when crushing, the external water pump inputs water into the water spray bar 203, and then sprays water from the water spray port on the water spray bar 203, thereby performing dust reduction treatment on the feed port 2001, and preventing the smoke and dust from floating out of the feed port 2001 and affecting the surrounding environment; it should be further noted that when the extrusion plate Ⅰ5 moves back and forth, the sliding plate 205 can be moved by the sliding plate 205 and the extrusion plate The adaptive deformation and extension of the elastic telescopic rod between Ⅰ5 makes the sliding plate 205 always keep in contact with the rotating frame 2, so that the smoke and dust generated by the crushing cannot enter from between the extrusion plate Ⅰ5 and the rotating frame 2 to the top of the extrusion plate Ⅰ5, thereby preventing the smoke and dust from floating out from the top of the extrusion plate Ⅰ5 and polluting the surrounding environment; it should be further noted that there is a situation where smoke and dust float out from the avoidance groove of the rotating frame 2, so the avoidance groove of the rotating frame 2 is always blocked by the dustproof strip Ⅰ204 to prevent the smoke and dust from floating out from the avoidance groove of the rotating frame 2 and polluting the surrounding environment, and by providing a sliding groove in the rotating frame 2 to accommodate the sliding of the dustproof strip Ⅰ204, the dustproof strip Ⅰ204 will not affect the up and down movement of the push plate 4 and the electric push rod Ⅰ6.

[0025] After the crushing work continues for a period of time, the larger concrete fragments in the rotating frame 2 are fully crushed, and there will be a large number of small concrete fragments in the rotating frame 2, which need to be discharged in time to avoid affecting the subsequent feeding. Therefore, the rotating frame 2 is driven by the motor I9 to rotate counterclockwise from front to back, so that the rotating frame 2 rotates along the guide rail 10001. It should be noted that in the initial state, the baffle 202 is in a state of being in contact with the inner bottom surface of the rotating frame 2, so it will block the concrete fragments to prevent the concrete fragments from falling off prematurely during the rotation process, resulting in a large amount of dust; when the rotating frame 2 rotates to fit the upper side surface of the crusher 8, the rotating frame 2 will cover the crusher 8, and the control motor I9 will stop rotating. Since the left side surface of the rotating frame 2 is the same size as the upper side surface of the crusher 8, the rotating frame 2 will completely cover the crusher 8 to prevent the concrete fragments in the rotating frame 2 from falling down in the future When the concrete is poured out, a large amount of dust generated will flow out from between the crusher 8 and the rotating frame 2, so that the dust can only flow out from the feeding port 2001 and be reduced by the water mist, so as to prevent the dust from floating out and polluting the surrounding environment; at this time, the electric push rod III 201 and the baffle 202 are both in a horizontal state, and the electric push rod III 201 is controlled to pull the baffle 202 to move to the left, so that the baffle 202 no longer blocks the concrete fragments in the rotating frame 2, and then the concrete fragments will enter the crusher 8 through the interception frame 102. However, since the steel bars are long and curved, the steel bars and the small amount of concrete adhered to the steel bars cannot pass through the interception frame 102, but continue to remain in the rotating frame 2. Then, after the concrete fragments are poured out, the motor I9 drives the rotating frame 2 to rotate and reset, so that the rotating frame 2 rotates to fit with the workbench 1, and then the electric push rod III 201 pushes the baffle 202 to reset, so that the baffle 202 fits with the inner bottom surface of the rotating frame 2 again.

[0026] After the concrete fragments in the rotating frame 2 are poured out, only a small amount of concrete fragments will be adhered to the steel bars at this time. Subsequently, the extrusion plate Ⅰ5 and the crushing plate 7 thereon are pushed downward by the hydraulic push rod 3. When the crushing plate 7 moves downward to contact the steel bars, the steel bars will be squeezed to make the steel bars bend. It should be noted that since the crushing plate 7 is wavy, the steel bars will be stuck in the recess of the crushing plate 7 when the steel bars are squeezed. Then, when the crushing plate 7 squeezes the steel bars to bend and the crushing plate 7 is difficult to continue to move downward, the hydraulic push rod 3 stops pushing, and then the electric push rod Ⅰ6 is controlled to push the extrusion plate Ⅰ5 to move back and forth repeatedly, so that the steel bars are repeatedly scraped by the crushing plate 7, and the remaining concrete fragments adhered to the steel bars are separated from the steel bars, further reducing the amount of concrete adhered to the steel bars, avoiding the problem that the staff in the prior art need to manually scrape the residual concrete on the steel bars, which not only increases the labor burden but also has extremely low efficiency; after the crushing plate 7 repeatedly scrapes the steel bars for a period of time, the extrusion plate Ⅰ5 is pulled upward by the hydraulic push rod 3 to reset.

[0027] Then, the motor I9 is ​​controlled again to drive the rotating frame 2 to rotate in the direction close to the crusher 8, so that the rotating frame 2 rotates to the state of covering the top of the crusher 8, and at this time, the electric push rod II 101 and the interception frame 102 are both in a horizontal state, and the motor I9 stops rotating. Then, the electric push rod III 201 is controlled again to pull the baffle 202 to move, so that the baffle 202 no longer blocks the concrete fragments, so that the broken concrete fragments are poured out from the rotating frame 2 first, and after the crusher 8 breaks the concrete fragments, the electric push rod II 101 is controlled again to pull the interception frame 102 to move to the left, so that the interception frame 102 no longer blocks the steel bars. The steel bars are intercepted and then fall into the crusher 8 for crushing, thereby breaking the steel bars into metal steel bar fragments. It should be noted that the staff collects the crushed concrete debris and metal fragments respectively by placing storage containers under the crusher 8, so as to facilitate the recycling of the metal fragments. After the steel bars in the rotating frame 2 are poured out, the motor I9 drives the rotating frame 2 to reset, and then the staff can pour the next batch of steel bars with concrete fragments to be processed into the rotating frame 2, thereby crushing the concrete fragments adhered to the next batch of steel bars, and so on and so forth to recycle the steel bar fragments.

[0028] Example 2 On the basis of Example 1, Figure 7-Figure 12 As shown, it also includes an extrusion plate II 301, a guide plate 302, a kneading plate 303, an electric push rod IV 304 and a motor II 305; the crusher 8 is provided with a discharge port 8001; the crusher 8 is slidably connected to two extrusion plates II 301, and the front and rear ends of each guide plate 302 penetrate the side wall of the crusher 8; the crusher 8 is rotatably connected to two guide plates 302, and the two guide plates 302 are both located below the discharge port 8001, and the guide plates 302 are in active contact with the adjacent extrusion plates II 301, and the extrusion plates II 301 and the guide plates 302 are all provided with sieve holes; the crusher 8 is fixedly connected with two kneading plates 303, and each kneading plate 303 is located above the extrusion plate Ⅱ301; the crusher 8 is fixedly connected with four rectangularly distributed electric push rods IV304, and the telescopic ends of every two front and rear corresponding electric push rods IV304 are fixedly connected with an extrusion plate Ⅱ301; four avoidance grooves are arranged on the crusher 8, and the extrusion plate Ⅱ301 slides on the corresponding avoidance grooves; the crusher 8 is fixedly connected with two motors Ⅱ305, and the output shaft of the motor Ⅱ305 is fixedly connected with the adjacent guide plate 302.

[0029] A plurality of grooves are arranged on the lower side of the rubbing board 303 to increase the roughness of the lower side of the rubbing board 303 so that the rubbing board 303 can more easily rub off the residual concrete layer on the metal fragments.

[0030] It also includes a dustproof strip II306; each extrusion plate II301 is fixedly connected to two front-to-back symmetrical dustproof strips II306, and the dustproof strip II306 is in the avoidance groove of the crusher 8, and the dustproof strip II306 is in contact with the avoidance groove, and the avoidance groove is shielded by the dustproof strip II306 to isolate the inside and outside of the crusher 8, thereby preventing concrete debris from falling through the avoidance groove of the crusher 8 and falling to the electric push rod IV304, affecting the operation of the electric push rod IV304.

[0031] It also includes a collecting frame I401 and a collecting frame II402; the collecting frame I401 is slidably connected to the bottom of the crusher 8, and the collecting frame I401 is directly below the extrusion plate II301 and the guide plate 302; two collecting frames II402 are slidably connected to the bottom of the crusher 8, and the two collecting frames II402 are respectively located on the left and right of the collecting frame I401; and the crusher 8 is provided with a partition plate 8002, which separates the collecting frame I401 from the two collecting frames II402.

[0032] It also includes a magnetic roller 403; the collecting frame I 401 is detachably connected to at least five magnetic rollers 403; the small pieces of metal fragments are sucked by the magnetic rollers 403 to prevent the small pieces of metal fragments from being mixed in the concrete debris.

[0033] The working steps of the above embodiment are as follows: after the crushing plate 7 moves back and forth to scrape the steel bars, a small amount of concrete fragments will still be adhered to some of the steel bars, so that when the steel bars are crushed, the steel bars and the concrete fragments on the steel bars will be completely crushed, resulting in a large amount of metal fragments and a small amount of concrete debris. Since the metal has a certain flexibility, the steel bars will be crushed into fragments with a spacing of not much different from that between the crushing wheels of the crusher 8, and the concrete will form smaller fragments and debris after crushing, so that the metal fragments and the concrete debris are There are differences in the sizes of concrete fragments and debris, and the extrusion plate II 301 and the guide plate 302 are provided with sieve holes, which are smaller than the size of standard metal fragments after being crushed by the crushing wheel, but larger than the size of concrete fragments and debris. After the concrete fragments and debris fall onto the extrusion plate II 301 and the guide plate 302, they will pass through the extrusion plate II 301 and the guide plate 302 and fall into the collection frame I 401, while the metal fragments will remain on the extrusion plate II 301 and the guide plate 302, thereby separating the metal fragments from the concrete fragments and debris.

[0034] In the initial state, the guide plate 302 is in a vertically upward state. At this time, the guide plate 302 does not block the lower part of the discharge port 8001. The guide plate 302 blocks the passage between the extrusion plate II 301 and the rubbing plate 303. When the crusher 8 crushes the concrete fragments, the concrete fragments and debris produced by the crushing will flow out from the discharge port 8001. The guide plate 302 prevents a large amount of concrete fragments and debris from falling onto the extrusion plate II 301, so that the concrete fragments and debris quickly fall into the collection frame I 401 below and are collected. Even if there are concrete fragments and debris that fall onto the extrusion plate II 301 through the sieve holes on the guide plate 302, they can also fall downward from the sieve holes of the extrusion plate II 301 to the collection frame I 401 for collection; and when the steel bars are crushed, the motor II 305 is first controlled to drive the two guide plates 302 to rotate toward each other. When the two guide plates 302 rotate to contact each other, the motor II 305 stops rotating, and at this time the guide plate 302 contacts the extrusion plate II 301, and the extrusion plate II 301 and the guide plate 302 are used to block the area directly below the discharge port 8001, so that the metal fragments produced by the crushing fall on the extrusion plate II 301 and the guide plate 302. Then, after the steel bars are crushed, the motor II 305 is controlled again to drive the two guide plates 302 to rotate in opposite directions, so that the guide plates 302 rotate to a vertically upward state, thereby pouring the metal fragments on the guide plates 302 onto the two extrusion plates II 301 respectively.

[0035] After the concrete fragments are crushed, a layer of concrete residue will be left on the surface of the steel bars, so that some concrete residue will exist on some metal fragments, which increases the difficulty of cleaning when the metal fragments are subsequently recovered. Therefore, after the metal fragments fall on the extrusion plate II 301, the electric push rod IV 304 pushes the extrusion plate II 301 to move up and down repeatedly, and it will not move to separate from the rubbing plate 303 when moving downward. The rubbing plate 303 blocks the metal fragments to prevent the metal fragments from sliding off the extrusion plate II 301, thereby driving the metal fragments on the extrusion plate II 301 to move up and down. When the extrusion plate II 301 moves upward, it drives the metal fragments to hit the rubbing plate 303 upward, thereby breaking the concrete residue layer on the metal fragments, and the rubbing plate 303 is provided with a plurality of grooves on the lower side, so that when the metal fragments hit the rubbing plate 303, the concrete residue layer on the metal fragments can be scraped off through the grooves on the rubbing plate 303, and the extrusion speed can be accelerated intermittently. The frequency of the up and down movement of the pressing plate II 301 and the reduced movement amplitude cause the metal fragments to shake on the extrusion plate II 301, and then the residual concrete layer shaken off will pass through the sieve holes of the extrusion plate II 301 and fall into the collection frame I 401, thereby avoiding the problem of increased cleaning difficulty when the metal fragments are subsequently recycled due to the presence of a partial residual concrete layer on some metal fragments; then after the residual concrete layer is fully shaken off, the electric push rod IV 304 is controlled to pull the extrusion plate II 301 downward, so that the extrusion plate II 301 moves to fit with the partition 8002. At this time, the extrusion plate II 301 will no longer contact the kneading plate 303, and the metal fragments will no longer be blocked by the kneading plate 303, so that the metal fragments slide off the extrusion plate II 301 and fall into the two collection frames II 402 respectively, and the metal fragments and concrete fragments and debris are collected separately, so that the present invention no longer requires the staff to frequently replace the storage container under the crusher 8, thereby reducing the workload of the staff.

[0036] When the steel bars are crushed, some small pieces of metal fragments will be generated, and the small pieces of metal fragments will pass through the sieve holes on the extrusion plate II 301 and the guide plate 302, causing the small pieces of metal fragments to be mixed in the concrete fragments and debris, resulting in the need for staff to pick out the small pieces of metal fragments later. Therefore, a magnetic roller 403 is arranged on the collection frame I 401, so that when the small pieces of metal fragments pass through the sieve holes on the extrusion plate II 301 and the guide plate 302 and fall, the magnetic roller 403 will absorb the small pieces of metal fragments to prevent the small pieces of metal fragments from being mixed in the concrete fragments and debris. After the work is completed, the staff will remove the magnetic roller 403 from the collection frame I 401, and clean the small pieces of metal fragments absorbed by the magnetic roller 403 into the collection frame II 402 to prevent the small pieces of metal fragments from being mixed in the concrete fragments and debris, and the staff will need to pick out the small pieces of metal fragments later, which will cause a workload problem for the staff.

[0037] Although the present invention is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications may be made to the present invention without departing from the principle and spirit of the present invention defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the present invention, but the scope of protection is limited by the content of the claims.
