[0028] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0030] Example

[0031] Please refer to the reference. Figures 1 to 4A concrete recycled aggregate impurity filtration device includes a filter box 1, an adsorption mechanism 5, a filter plate 2, and a collection box 6 movably disposed within the filter box 1; the collection box 6 is disposed below the filter plate 2; the adsorption mechanism 5 includes an adsorption rod 501, a scraper 504, and a recovery box 507; the scraper 504 is connected to the filter box 1 and has scraping holes; the adsorption rod 501 is movably disposed within the scraping holes, and the outer wall of the adsorption rod 501 contacts the inner wall of the scraping holes; the recovery box 507 is movably disposed within the filter box 1 and is disposed below the scraper 504.

[0032] In this embodiment of the concrete recycled aggregate impurity filtration device, the filter plate 2 can be provided with filter holes. The recycled aggregate can be screened and filtered through the filter plate 2, allowing it to fall into the collection box 6, while large particles and impurities are filtered out. The collection box 6 collects the aggregate filtered by the filter plate 2, facilitating the transfer and transportation of the filtered aggregate by workers. The adsorption rod 501 can be a metal adsorption rod, for example, the material of the adsorption rod 501 can be a magnet. The adsorption rod 501 can adsorb metals such as iron carried in the aggregate. When the adsorption rod 501 moves in the scraping hole, the metal impurities adsorbed on the surface of the adsorption rod 501 will be scraped off by the scraping action of the scraper 504 and fall into the recycling box 507. This allows the device to filter out the metal impurities in the recycled aggregate separately, which is convenient for metal recycling and reduces the production cost of recycled concrete. At the same time, it can also prevent small metal particles from passing through the filter plate 2 and falling into the collection box 6, so that the filtered aggregate does not contain metal and prevents metal from entering the recycled concrete and affecting the strength and quality of the concrete.

[0033] The filter box 1 can be a rectangular box. The filter plate 2 can be a horizontal rectangular plate. The collection box 6 can be a rectangular box with an open top surface. The adsorption rod 501 can be a horizontal rectangular rod. The scraper 504 can be a vertical rectangular plate with its surface perpendicular to the adsorption rod 501. The scraping holes can be rectangular through holes. The recovery box 507 can be a rectangular box with an open top surface.

[0034] Please refer to the reference. Figure 3 and Figure 5 Specifically, an inclined receiving plate 505 is provided below the scraper 504, and the lower end of the receiving plate 505 is located above the recycling box 507; a mounting bracket 506 is fixedly connected inside the filter box 1, and a first through hole is opened on the side wall of the filter box 1. The recycling box 507 is movably mounted on the mounting bracket 506 and movably located in the first through hole.

[0035] The recycling box 507 can be movably passed through the first through hole, so that the recycling box 507 passes through the filter box 1 and is slidably connected to the filter box 1; the receiving plate 505 is inclined toward the recycling box 507, so that when the metal on the surface of the adsorption rod 501 is scraped off by the scraper 504, it can slide into the recycling box 507 through the receiving plate 505.

[0036] The outer surface of the recycling box 507 can be fitted with a handle, which allows staff to pull the recycling box 507 out of the filter box 1, making it easier to recycle metal impurities and reducing the workload of staff manually collecting metal impurities.

[0037] The receiving plate 505 can be set as an inclined rectangular plate. The first through hole can be set as a rectangular through hole.

[0038] Specifically, the scraper 504 is connected to the filter box 1 via the fixing plate 503; the fixing plate 503 has a second through hole, and the adsorption rod 501 is movably disposed in the second through hole; the upper end of the receiving plate 505 is connected to the lower end of the fixing plate 503; the adsorption mechanism 5 also includes a support plate 502, which is connected to the filter box 1; the support plate 502 has a third through hole, and the adsorption rod 501 is fixedly connected in the third through hole.

[0039] By connecting the scraper 504 to the fixed plate 503 and the support plate 502, and then connecting the fixed plate 503 and the support plate 502 to the filter box 1, it is easy to connect the scraper 504 to the filter box 1 and improve the firmness and stability of the connection between the scraper 504 and the filter box 1.

[0040] The outer diameter of the second through hole can be larger than the outer diameter of the adsorption rod 501, so that the second through hole forms a groove for the adsorption rod 501 to move. The adsorption rod 501 is located in the middle of the second through hole, that is, there is no contact between the inner wall of the second through hole and the outer wall of the adsorption rod 501. In other words, there is no contact between the fixing plate 503 and the adsorption rod 501, thereby preventing the fixing plate 503 from scraping off the metal adsorbed on the surface of the adsorption rod 501 and dropping it onto the filter plate. This helps to ensure that the metal adsorbed on the surface of the adsorption rod 501 is only scraped off by the scraper 504 and falls into the recycling box 507.

[0041] The second and third through holes can be rectangular through holes. Both the fixing plate 503 and the support plate 502 can be vertical rectangular plates. The top surface of the receiving plate 505 is connected to the bottom surface of the fixing plate 503.

[0042] Specifically, the adsorption mechanism 5 also includes an electric push rod 508, the end of which is connected to the connecting frame 509; one end of the adsorption rod 501 is connected to the connecting frame 509; at least two adsorption rods 501 are provided, and the number of second through holes and the number of third through holes are equal to the number of adsorption rods 501.

[0043] The end of the electric push rod 508 is fixedly connected to the connecting frame 509, and each adsorption rod 501 is also fixedly connected to the connecting frame 509. The electric push rod 508 can be programmed to extend and retract periodically, allowing it to periodically move the adsorption rods 501 via the connecting frame 509. This causes the scraper 504 to scrape away the metal impurities adsorbed on the surface of the adsorption rods 501, achieving automatic cleaning of adsorbed metal. Multiple adsorption rods 501 form a group, improving the adsorption efficiency and effectiveness for metal impurities.

[0044] The electric actuator 508 can be a product of existing technology. The electric actuator 508 can be fixedly connected to the inner surface of the side wall of the filter box 1. Multiple adsorption rods 501 are parallel to each other and can be arranged at equal intervals.

[0045] Specifically, the adsorption mechanism 5 is located above the filter box 1, and the top surface of the fixed plate 503 and the top surface of the support plate 502 are connected to the top surface of the filter box 1; the scraper 504 is connected to the fixed plate 503 through the connecting rod 510.

[0046] The system comprises an electric push rod 508 connected to a connecting frame 509, and an adsorption rod 501 connected sequentially to the connecting frame 509, a support plate 502, a fixing plate 503, and a scraper 504. The fixing plate 503 is connected to the scraper 504 via a connecting rod 510, forming a robust and stable adsorption mechanism 5. When the adsorption rod 501 is pushed by the connecting frame 509 through the support plate 502, the fixing plate 503, and the scraper 504, the metal impurities adsorbed on the surface of the adsorption rod 501 are scraped off and fall onto the receiving plate 505 by the obstruction of the scraper 504.

[0047] The connecting rod 510 can be set as a horizontal round rod. Each scraper 504 can be connected to the fixed plate 503 through four connecting rods 501, and the four connecting rods 501 are evenly and symmetrically distributed in a rectangle on the scraper 504.

[0048] Please refer to the reference. Figure 2 , Figure 3 and Figure 5 Specifically, a rotating shaft 3 is rotatably installed inside the filter box 1, and both ends of the rotating shaft 3 are connected to two transmission mechanisms 4 respectively. The transmission mechanism 4 includes a protective box 401, a transmission frame 402, an eccentric wheel 403, and two transmission rods 404. The protective box 401 is connected to the filter box 1, and the transmission frame 402 is movably disposed inside the protective box 401. The eccentric wheel 403 is disposed inside the transmission frame 402 and is connected to the end of the rotating shaft 3. A fourth through hole is opened on the top and bottom surfaces of the protective box 401 respectively. One end of the two transmission rods 404 is connected to the top and bottom surfaces of the transmission frame 402 respectively, and the other end moves through the fourth through hole respectively. Both ends of the filter plate 2 are connected to the transmission rods 404 of the two transmission mechanisms 4 respectively.

[0049] Each transmission rod 404 passes through the fourth through hole, that is, through the protective box 401, and can move up and down within the fourth through hole. The filter plate 2 is fixedly connected to the transmission rod 404. The rotation of the rotating shaft 3 drives the eccentric wheel 403 to rotate. The rotation of the eccentric wheel 403 drives the transmission frame 402 to reciprocate and lift, thereby driving the transmission rod 404 and the connected filter plate 2 to reciprocate and lift, thus providing power for the vibrating screening of the filter plate 2, enabling the filter plate 2 to vibrate and perform vibrating screening of recycled aggregate, effectively improving the filtration effect.

[0050] The protective box 401 serves to protect the normal operation of the other components of the transmission mechanism 4 and prevent the aggregate passing through the filter plate 2 from affecting the normal transmission process of the transmission mechanism 4. At the same time, the protective box 401 also provides support and limits for the up and down movement of the transmission rod 404, so that the transmission rod 404 can remain stable during the up and down movement.

[0051] The rotating shaft 3 is a horizontal cylindrical shaft. The protective box 401 is a rectangular box with an open structure at its outer end, and is connected to the side wall of the filter box 1. The transmission rod 404 can be a vertical rectangular rod, and the fourth through hole is a rectangular through hole.

[0052] One end of each of the two transmission rods 404 is in contact with or fixedly connected to the top and bottom surfaces of the transmission frame 402, respectively. The other end of the upper transmission rod 404, i.e. the top end, can be in contact with or fixedly connected to the bottom surface of the filter plate 2.

[0053] Please refer to the reference. Figures 1 to 3 and Figure 5 Specifically, the protective box 401 is connected to the inner wall of the filter box 1; a fifth through hole is opened on the side wall of the protective box 401, and the rotating shaft 3 is movably installed in the fifth through hole; a sixth through hole is opened on the side wall of the filter box 1, and the rotating shaft 3 is rotatably installed in the sixth through hole, with one end of the rotating shaft 3 extending out to the outside of the filter box 1 through the sixth through hole; a servo motor 405 is connected to the side wall of the filter box 1, and one end of the rotating shaft 3 is coaxially connected to the rotation output shaft of the servo motor 405; the top and bottom surfaces of the transmission frame 402 are both set as horizontal planes, and the two transmission rods 404 of each transmission mechanism 4 are set on the same vertical line.

[0054] By activating the servo motor 405, the rotating shaft 3 can be driven to rotate, thereby providing power to the transmission mechanism 4.

[0055] The servo motor 405 can be a product using existing technology. The servo motor 405 can be fixedly connected to the outer surface of the side wall of the filter box 1, that is, the servo motor 405 can be fixedly connected to the outside of the filter box 1.

[0056] The protective box 401 can be fixedly connected to the inner surface of the side wall of the filter box 1. The fifth through hole is opened on the inner side wall of the protective box 401. Both the fifth and sixth through holes are round holes, and the rotating shaft 3 is rotatably disposed in the fifth and sixth through holes.

[0057] Please refer to the reference. Figure 2 and Figure 3 Specifically, the filter plate 2 is set as an inclined plate, and a seventh through hole is opened on the side wall of the filter box 1; the lower end of the filter plate 2 moves through the seventh through hole and extends to the outside of the filter box 1.

[0058] The inclined filter plate 2 allows large particles and impurities left on the filter plate 2 to slide out of the filter box 1 through the filter plate 2 and the seventh through hole.

[0059] The seventh through hole can be a rectangular hole, with its vertical height greater than the thickness of filter plate 2 and the sum of its vertical vibration distance; the horizontal width of the seventh through hole can be greater than the width of filter plate 2 and the sum of its horizontal vibration distance, so as to avoid obstructing the vertical or horizontal vibration of filter plate 2. Simultaneously, the seventh through hole allows filter box 1 to provide support and limit the vibration of filter plate 2. Here, "left" and "right" refer to... Figure 5 The left and right directions are shown.

[0060] Please refer to the reference. Figures 1 to 3 Specifically, the filter box 1 has an eighth through hole on its side wall, the collection box 6 is movably installed in the eighth through hole, and the side wall of the collection box 6 is provided with a handle.

[0061] The handle allows staff to easily pull the collection box 6 out of the eighth through hole of the filter box 1, thus forming a drawer structure for the collection box 6.

[0062] The handle can be located on the outer sidewall of the collection box 6, and this outer sidewall is only located at the position of the eighth through hole. The eighth through hole is a rectangular through hole.

[0063] Please refer to Figure 1 Specifically, a dust collector 7 is installed on the top of the filter box 1, and a feed inlet 8 is opened on the top surface of the filter box 1. The feed inlet 8 is located above the adsorption rod 501 and the filter plate 2, and is connected to a feed hopper.

[0064] The dust collector 7 can adsorb and treat the dust generated during the filtration process inside the filter box 1, preventing dust from scattering and polluting the surrounding environment. The feed inlet 8 allows workers to easily transport the recycled concrete aggregate into the filter box 1, and the recycled concrete aggregate falls onto the filter plate 2 after passing through the adsorption rod 501.

[0065] The dust collector 7 can be a product using existing technology. The feed hopper is designed as a funnel structure.

[0066] Please refer to the reference. Figures 1 to 5 In this embodiment of the concrete recycled aggregate impurity filtration device, when filtering recycled aggregate, the operator can first start the servo motor 405, and then feed the recycled aggregate into the filter box 1 through the feed inlet 8; when the recycled aggregate passes through the adsorption rod 501, the adsorption rod 501 can adsorb the metal impurities carried in the recycled aggregate; then the electric push rod 508 is started, and the electric push rod 508 can drive the adsorption rod 501 to move through the connecting frame 509; when the adsorption rod 501 passes through the scraper 504, the scraper 504 scrapes the metal impurities adsorbed by the adsorption rod 501 onto the receiving plate 505, and the metal impurities are removed. The aggregate slides down the receiving plate 505 into the recycling box 507, facilitating the subsequent recovery of metal impurities by staff. The recycled aggregate passing through the adsorption rod 501 is filtered by the filter plate 2 and falls into the collection box 6. The servo motor 405 drives the rotating shaft 3 to rotate, which in turn drives the eccentric wheel 403 to rotate. The eccentric wheel 403 drives the transmission frame 402 to move up and down repeatedly. The reciprocating movement of the transmission frame 402 drives the filter plate 2 to vibrate through the transmission rod 404, thereby enabling the filter plate 2 to filter the recycled aggregate. Finally, the staff pulls out the collection box 6 and transfers the collected aggregate.
