Description

Technical Field

[0001] This utility model relates to the field of construction waste treatment technology, specifically to a scrap iron recycling device for construction waste. Background Technology

[0002] Construction waste refers to waste generated during construction, demolition, and repair processes, including discarded concrete, bricks, tiles, wood, and steel bars. If not properly disposed of, this waste can pollute and harm the environment. However, construction waste contains some scrap iron, which can be recycled. Therefore, scrap iron recycling equipment is needed to classify and recycle construction waste.

[0003] For example, patent document CN218796499U discloses a construction waste scrap iron recycling device. The technology includes a first housing, with a feeding port at the top for waste concrete blocks to enter. A crushing component, arranged in a left-right clamping configuration, is installed inside a hydraulic cylinder to crush the concrete blocks entering the first housing. A discharge port at the bottom of the first housing allows the passage of slag and scrap iron. A first baffle, hinged to the discharge port, swings up and down. A shell is located at the bottom of the first housing, with a buffer assembly on its inner sidewall. The buffer assembly includes two second baffles, with an adsorption assembly for adsorbing scrap iron positioned between the two baffles. A conveying assembly at the bottom of the shell is used to transport the slag and scrap iron separately. This design facilitates the crushing of waste concrete blocks, thereby making it easier to separate scrap iron and collect and transport scrap iron and slag separately. However, this existing technology still has many shortcomings. For example, when recycling scrap iron, it mainly uses a first electromagnet and a second electromagnet to adsorb and separate the scrap iron in the crushed construction waste. However, the first electromagnet and the second electromagnet have little contact with the construction waste, which can easily lead to incomplete recycling of scrap iron and thus waste of scrap iron resources.

The piston rods of the two electric push rods are fixedly connected to the same support frame, and the cross-section of the support frame is V-shaped.

[0007] As a further improvement to the above solution, mounting plates are fixedly connected to the inner walls of both ends of the recovery shell, the support frame is located between the two mounting plates, and a second guide block is fixedly connected to the top of the support frame.

[0008] As a further improvement to the above solution, both sides of the support frame are fixedly connected to fixing plates, and both sides of the recycling shell are opened with connection ports. The inner walls of the connection ports are slidably connected to connecting blocks. The opposite sides of the two connecting blocks are fixedly connected to the two fixing plates respectively, and the opposite sides of the connecting blocks are fixedly connected to the two connecting plates respectively.

[0009] As a further improvement to the above solution, a first guide block is fixedly connected to the top of each of the two mounting plates, and the opposite sides of the two first guide blocks are designed to be inclined.

[0010] As a further improvement to the above solution, the crushing mechanism includes two crushing rollers rotatably connected to the inner walls of both sides of the recycling shell. Two meshing transmission gears are rotatably connected to one outer wall of the recycling shell. The two transmission gears are fixedly disposed between the two crushing rollers respectively.

[0012] As a further improvement to the above solution, the bottom inner wall of the movable port is provided with three sliding grooves, and the bottom outer walls of the two first collection frames and the second collection frame are fixedly connected with sliding plates that are adapted to the sliding grooves, and the sliding plates are inserted into the sliding grooves.

[0013] As a further improvement to the above solution, a second baffle is fixedly connected to the inner walls of both sides of the recycling shell, and the second baffle is located between one of the first collection frames and the second collection frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes a method where first baffles are rotatably connected to both ends of the inner walls on both sides of a recycling shell, with the two first baffles staggered. Electromagnets are embedded in the top of each first baffle. First and second gears, meshing with each other, are rotatably connected to both ends of the outer walls on both sides of the recycling shell. When recycling scrap iron from construction waste, the construction waste is first fed into the recycling shell through a hopper. Then, a crushing mechanism crushes the construction waste. The crushed construction waste falls between two mounting plates, first contacting the upper first baffle. The electromagnet on the upper first baffle attracts the scrap iron from the crushed construction waste. The crushed construction waste continues to fall, landing on the lower first baffle. Above, an electromagnet located on the first baffle below re-attracts scrap iron from the shredded construction waste. The electromagnet makes full contact with the scrap iron, avoiding incomplete recycling and resource waste. The shredded construction waste eventually falls into the second collection box. After the scrap iron is recycled, an electric push rod moves upward, causing the connecting plate to move upward, which in turn drives two transmission racks to move upward. The transmission racks drive the second gear to rotate through the first gear, which in turn drives the first baffle to flip downward, making the first baffle vertical. At this time, the electromagnet is de-energized, and the scrap iron on the first baffle loses its attraction and falls into the first collection box, facilitating the separation of scrap iron from the shredded construction waste.

[0016] This invention uses two electric push rods fixedly connected to the top sides of a support plate. The piston rods of the two electric push rods are fixedly connected to the same support frame. During use, the electric push rods drive the support frame to move downwards, and the pulverized construction waste falls through the gap between the mounting plate and the support frame, and falls down the inclined surface of the support frame onto the first baffle located above. The feeding speed of the pulverized construction waste can be adjusted by adjusting the height of the support frame. During the downward movement of the support frame, the connecting plate is driven to move downwards through the fixed plate and connecting block, and then the two first baffles are driven to tilt upwards through the transmission rack, first gear and second gear, so that the pulverized construction waste can be recycled normally. When it is necessary to discharge the scrap iron on the first baffle, the electric push rod drives the support frame to move upwards, and then drives the support frame and the second guide block to contact the mounting plate. At this time, the construction waste cannot fall, and the upward movement of the support frame will drive the first baffle to move downwards to a vertical state. At this time, the electromagnet is de-energized to discharge the scrap iron, thus facilitating the discharge of scrap iron. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0027] A scrap iron recycling device for construction waste, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the device includes a recycling shell 1, a control panel 2 on the front outer wall of the recycling shell 1, a feed inlet 8 on the top of the recycling shell 1, and a feed hopper 5 bolted to the top outer wall of the recycling shell 1. A crushing mechanism 3 is located at the top of the inner wall of the recycling shell 1. Two first baffles 9 are rotatably connected to both ends of the inner walls on both sides of the recycling shell 1. The two first baffles 9 are staggered. An electromagnet 10 is embedded in the top of the first baffle 9. A first gear 16 and a second gear 17 are rotatably connected to both ends of the outer walls on both sides of the recycling shell 1. The second gear 17 is fixedly connected to the first baffle 9. Two parallel transmission racks 18 are slidably arranged on both outer walls of the recycling shell 1. The two transmission racks 18 mesh with the two first gears 16 respectively. The tops of the two transmission racks 18 on the same side are bolted to the same connecting plate 15. The connecting plate 15 is driven by two electric push rods 20. A collection mechanism 4 is located at the bottom of the recycling shell 1.

[0028] like Figure 4 and Figure 5As shown, the crushing mechanism 3 includes two crushing rollers 301 rotatably connected to the inner walls of both sides of the recycling housing 1. Two meshing transmission gears 302 are rotatably connected to one outer wall of the recycling housing 1. The two transmission gears 302 are fixedly disposed between the two crushing rollers 301 respectively. A crushing motor 303 is bolted to the other outer wall of the recycling housing 1. The output shaft of the crushing motor 303 is fixedly disposed between the output shaft of the crushing motor 303 and one of the crushing rollers 301. The crushing motor 303 drives one of the crushing rollers 301 to rotate. The crushing roller 301 drives the other crushing roller 301 to rotate in the opposite direction at the same speed through the transmission gear 302, thereby crushing the construction waste.

[0029] like Figures 2 to 4 As shown, the collection mechanism 4 includes two first collection frames 401 and a second collection frame 402. A movable opening 406 is located at the bottom of one side of the recycling housing 1. The two first collection frames 401 and the second collection frame 402 are inserted into the inner wall of the movable opening 406. Handles 403 are bolted to the outer wall of one side of each of the two first collection frames 401 and the second collection frame 402. Scrap iron is collected through the two first collection frames 401, and construction waste is collected through the second collection frame 402. Three sliding grooves 405 are located on the bottom inner wall of the movable opening 406. The bottom outer wall of the collection frame 402 is bolted with a sliding plate 404 that matches the sliding groove 405. The sliding plate 404 is inserted into the sliding groove 405. The sliding groove 405 and the sliding plate 404 facilitate the pulling of the first collection frame 401 and the second collection frame 402. The inner walls of both sides of the recycling shell 1 are bolted with a second baffle 11. The second baffle 11 is located between one of the first collection frames 401 and the second collection frame 402. The second baffle 11 blocks the material from the first baffle 9 located below, preventing construction waste from falling into the first collection frame 401.

[0030] In Example 1, when recycling scrap iron from construction waste, the construction waste is first fed into the recycling shell 1 through the feed hopper 5. Then, the construction waste is crushed by the crushing mechanism 3. The crushed construction waste falls between two mounting plates 6, first contacting the upper first baffle 9. The electromagnet 10 on the upper first baffle 9 attracts the scrap iron in the crushed construction waste. The crushed construction waste continues to fall onto the lower first baffle 9, where the electromagnet 10 on the lower first baffle 9 attracts the scrap iron again. The electromagnet 10 fully interacts with the scrap iron. To avoid incomplete scrap iron recycling and resource waste, the crushed construction waste eventually falls into the second collection box 402. After the scrap iron is recycled, the electric push rod 20 can be moved upward, driving the connecting plate 15 to move upward, thereby driving the two transmission racks 18 to move upward. The transmission racks 18 drive the second gear 17 to rotate through the first gear 16, thereby driving the first baffle 9 to flip downward, so that the first baffle 9 flips into a vertical state. At this time, the electromagnet 10 is de-energized, and the scrap iron on the first baffle 9 loses the attraction of the electromagnet 10 and falls into the first collection box 401, which facilitates the separation of scrap iron from the crushed construction waste. Example 2

[0031] Example 2 is based on Example 1, such as... Figure 6 and Figure 7 As shown, support plates 19 are bolted to the inner walls of both sides of the recycling shell 1. Two electric push rods 20 are bolted to the top sides of the support plates 19, and the piston rods of the two electric push rods 20 are bolted to the same support frame 12. The support frame 12 has a V-shaped cross-section. The electric push rods 20 drive the support frame 12 to move up and down, thereby adjusting the feeding speed of the crushed construction waste. Mounting plates 6 are bolted to the inner walls of both ends of the recycling shell 1. The support frame 12 is located between the two mounting plates 6. A second guide block 22 is bolted to the top of the support frame 12. The second guide block 22 guides the crushed construction waste, allowing it to flow along the second guide block. The inclined surfaces of the support frame 12 and the support frame 12 rest on the first baffle 9; both sides of the support frame 12 are bolted to the fixing plates 13, and both sides of the recycling shell 1 have connection ports 21. The inner walls of the connection ports 21 are slidably connected to the connecting blocks 14. The opposite sides of the two connecting blocks 14 are bolted to the two fixing plates 13, and the opposite sides of the connecting blocks 14 are bolted to the two connecting plates 15. The connection ports 21 and the connecting blocks 14 facilitate the up and down movement of the connecting plates 15; the tops of the two mounting plates 6 are bolted to the first guide blocks 7. The opposite sides of the two first guide blocks 7 are inclined. The first guide blocks 7 prevent the crushed construction waste from remaining on the mounting plates 6.

[0032] In Example 2, during use, the electric push rod 20 drives the support frame 12 to move downwards. The pulverized construction waste falls through the gap between the mounting plate 6 and the support frame 12, and falls onto the first baffle 9 located above along the inclined surface of the support frame 12. The feeding speed of the pulverized construction waste can be adjusted by adjusting the height of the support frame 12. During the downward movement of the support frame 12, the connecting plate 15 is driven to move downwards through the fixing plate 13 and the connecting block 14. Then, through the transmission rack 18, the first gear 16 and the second gear 17, the two first baffles 9 are driven to tilt upwards, so that the pulverized construction waste can be recycled normally. When it is necessary to feed the scrap iron on the first baffle 9, the electric push rod 20 drives the support frame 12 to move upwards, and then drives the support frame 12 and the second guide block 22 to contact the mounting plate 6. At this time, the construction waste cannot fall, and the upward movement of the support frame 12 will drive the first baffle 9 to move downwards to a vertical state. At this time, the electromagnet 10 is de-energized to feed the scrap iron, which facilitates the feeding of scrap iron.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
