Description

Technical Field

[0001] This invention relates to the field of material recycling technology, and in particular to a smart city material sorting and recycling device. Background Technology

[0002] Currently, some building materials or materials from processing plants and manufacturing plants often contain a lot of magnetic iron filings. Iron filings are an important recyclable resource. After recycling, iron filings can be used to manufacture composite materials, new building materials and decorative materials, and new furniture.

[0003] In existing technologies, some methods for processing mixtures of magnetic iron filings involve directly crushing the mixture before unified processing. However, this makes it difficult to separate the magnetic iron filings, hindering their classification, recycling, and reuse, thus wasting these resources. Other methods use electromagnets. When the electromagnet is turned on, it attracts the magnetic iron filings to its surface. When it is turned off, the electromagnet loses its magnetism, and the iron filings fall off, allowing for separation and recycling. However, when the electromagnet is turned off after a period of operation, its surface does not immediately lose magnetism; a weak magnetism remains. Therefore, when the electromagnet is turned off after attracting iron filings for a while, most of the filings fall off, but a small portion remains adsorbed on the electromagnet's surface. This not only affects the subsequent separation process but also wastes iron filings. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies in separating and classifying magnetic iron filings in mixed materials, and to propose a smart city material classification and recycling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The two electromagnets are rotatably connected to the housing through the driving device. The two chip removal mechanisms are both located in the housing. The two chip removal mechanisms are used to remove iron filings remaining on the outer surface of the two electromagnets after power is cut off.

The chip scraping mechanism is disposed inside the housing via the rotating and retracting mechanism, and the rotating and retracting mechanism is disposed on the outer side wall of the housing.

[0008] Preferably, the scraping mechanism includes a bracket and a scraper. The bracket is connected to the rotating and retracting mechanism, the scraper is fixedly connected to the lower end of the bracket, and the scraper can be placed on the upper end of the outer surface of the electromagnet.

[0009] Preferably, the rotating and retracting mechanism includes a first gear, a first bevel gear, a second bevel gear, and an intermittent forward and reverse rotation mechanism. The first gear is rotatably connected to the housing and is fixedly connected to one end of the bracket. The first bevel gear is fixedly connected to one side of the first gear. The second bevel gear is rotatably connected to the housing and meshes with the first bevel gear. The intermittent forward and reverse rotation mechanism is disposed on one side of the second bevel gear.

[0010] Preferably, the intermittent forward and reverse rotation mechanism includes a second gear, a third gear, a first arc-shaped rack, a fourth gear, a second arc-shaped rack, a sector gear, and a motor. The second gear is rotatably connected to the housing, and the second gear is fixedly connected to the second bevel gear. The third gear is rotatably connected to the housing. The first arc-shaped rack is fixedly connected to one side of the third gear. The fourth gear is rotatably connected to the housing and meshes with the third gear.

The sector gear is rotatably connected to the housing and meshes with the fourth gear. The motor is fixedly connected to the housing, and one end of the motor's output shaft is fixedly connected to the sector gear.

[0011] Preferably, the bracket is provided with a cleaning mechanism, and the cleaning mechanism is located on the upper surface of the scraper. The cleaning mechanism includes a first friction wheel, a second friction wheel, and a cleaning blade. The first friction wheel is rotatably connected to the bracket, the second friction wheel is fixedly connected to one end of the electromagnet, and the second friction wheel and the first friction wheel are connected by friction transmission. The cleaning blade is rotatably connected to the bracket, and one end of the cleaning blade is fixedly connected to the first friction wheel.

[0012] Preferably, the upper end of the bracket is provided with a chip removal mechanism, which includes an air duct and a extraction pipe.

[0016] The smart city material sorting and recycling equipment proposed in this invention has the following advantages:

[0017] 1. This smart city material sorting and recycling equipment uses two electromagnets and a drive device. When the two electromagnets are turned on, they can attract magnetic iron filings in the mixture. When the two electromagnets are turned off, most of the iron filings attracted on their outer surfaces will fall off directly. This allows for easy separation and sorting of magnetic iron filings and non-magnetic materials in the mixture, thus facilitating the recycling of these materials.

[0018] 2. Through the setting of the chip removal mechanism, under the action of the chip scraping mechanism and the rotating take-up and release mechanism, a small amount of residual iron chips that were attracted and adsorbed on the outer surface of the electromagnet when it is closed and loses its magnetism can be easily scraped off. This allows for a thorough cleaning of the outer surface of the electromagnet, preventing excessive iron chips from remaining on the outer surface of the electromagnet and affecting the subsequent process of attracting iron chips, and also avoiding the waste of iron chip resources.

[0019] 3. Through the cleaning mechanism, the iron filings left on the surface of the scraper can be easily swept away by the action of the first friction wheel, the second friction wheel, and the cleaning blades. Furthermore, through the chip extraction mechanism, the iron filings swept off the surface of the scraper can be easily extracted and sorted for recycling by the action of the air duct and extraction pipe. This avoids leaving too many iron filings on the scraper during the scraping of the electromagnet, and allows for a comprehensive cleaning of the remaining iron filings. This not only enables better separation and recycling of iron filings in the subsequent mixture, but also ensures more thorough and complete recycling of iron filings in the mixture, avoiding waste of iron filings resources.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example

[0039] Reference Figure 1-2 A smart city material sorting and recycling device includes two electromagnets 4, a drive device 5, and two chip removal mechanisms. The two electromagnets 4 are rotatably connected to the housing 1 through the drive device 5. A crushing device 3 is installed in the housing 1. A feeding hopper 2 is fixedly connected to the upper end of the housing 1, and a discharge port is provided at the lower end of the housing 1. The crushing device 3 is used to crush the mixed materials fed from the feeding hopper 2. The two chip removal mechanisms are both installed in the housing 1, and each chip removal mechanism is used to remove the iron filings remaining on the outer surface of the two electromagnets 4 after the power is turned off.

[0040] The mixed material is fed into the shell 1 through the feeding hopper 2. Simultaneously, the crushing device 3 is activated to crush the fed material. The crushed material falls directly to the ground. At the same time, two electromagnets 4 are activated, generating magnetism. The drive device 5 controls the two electromagnets 4 to rotate in opposite directions. The falling crushed material passes between the two activated electromagnets 4, which then attract and remove any magnetic iron filings from the material. The iron filings are adsorbed onto the outer surface of the mixture, while the remaining non-magnetic, non-iron filings fall directly through the two electromagnets 4. Finally, the non-magnetic, non-iron filings are discharged through the outlet at the lower end of the shell 1. At this time, the non-magnetic, non-iron filings in the mixed material can be sorted and recycled. When the two electromagnets 4 are turned off, they lose their magnetism, and the iron filings adsorbed on the outer surface of the two electromagnets 4 fall off and are discharged through the outlet at the lower end of the shell 1. At this time, the magnetic iron filings in the mixed material can be sorted and recycled. Therefore, by setting up two electromagnets 4 and a driving device 5, when the two electromagnets 4 are turned on, they can attract magnetic iron filings in the mixture. When the two electromagnets 4 are turned off, most of the iron filings attracted on their outer surfaces will fall directly. This makes it easy to separate and classify the magnetic iron filings and non-magnetic non-iron filings in the mixture, and thus make it easy to classify and recycle the magnetic iron filings and non-magnetic non-iron filings in the mixture. Example

[0041] Reference Figure 2-9As another preferred embodiment of the present invention, the difference from embodiment 1 is that the chip removal mechanism includes a chip scraping mechanism 6 and a rotating and retracting mechanism 7. The chip scraping mechanism 6 is disposed inside the housing 1 through the rotating and retracting mechanism 7, and the rotating and retracting mechanism 7 is disposed on the outer side wall of the housing 1. The chip scraping mechanism 6 includes a bracket 601 and a scraper 607. The bracket 601 is connected to the rotating and retracting mechanism 7, and the scraper 607 is fixedly connected to the lower end of the bracket 601. The scraper 607 can be placed on the upper end of the outer surface of the electromagnet 4.

[0042] The rotating take-up and take-down mechanism 7 includes a first gear 701, a first bevel gear 702, a second bevel gear 703, and an intermittent forward and reverse rotation mechanism. The first gear 701 is rotatably connected to the housing 1 and is fixedly connected to one end of the bracket 601. The first bevel gear 702 is fixedly connected to one side of the first gear 701. The second bevel gear 703 is rotatably connected to the housing 1 and meshes with the first bevel gear 702. The intermittent forward and reverse rotation mechanism is located on one side of the second bevel gear 703.

[0043] The intermittent forward and reverse rotation mechanism includes a second gear 704, a third gear 705, a first arc-shaped rack 706, a fourth gear 707, a second arc-shaped rack 708, a sector gear 709, and a motor 710. The second gear 704 is rotatably connected to the housing 1, and the second gear 704 is fixedly connected to the second bevel gear 703. The third gear 705 is rotatably connected to the housing 1. The first arc-shaped rack 706 is fixedly connected to one side of the third gear 705. The fourth gear 707 is rotatably connected to the housing 1, and the fourth gear 707 meshes with the third gear 705. The second arc-shaped rack 708 is fixedly connected to one side of the fourth gear 707, and the second arc-shaped rack 708 and the first arc-shaped rack 706 can respectively mesh with the lower end and the upper end of the second gear 704. The sector gear 709 is rotatably connected to the housing 1, and the sector gear 709 can mesh with the fourth gear 707. The motor 710 is fixedly connected to the housing 1, and one end of the output shaft of the motor 710 is fixedly connected to the sector gear 709. The motor 710 is connected to an external power supply device through a wire, and a switch for controlling the operation of the motor 710 is provided on the wire.

[0044] By starting the motor 710, the motor 710 drives the sector gear 709 to rotate continuously. The sector gear 709 then drives the fourth gear 707 to rotate intermittently. The fourth gear 707 drives the second arc-shaped rack 708 to rotate intermittently in the same direction. The fourth gear 707 also drives the third gear 705 to rotate intermittently in the opposite direction. The third gear 705 then drives the first arc-shaped rack 706 to rotate intermittently in the opposite direction to the second arc-shaped rack 708. Thus, the first arc-shaped rack 706 and the second arc-shaped rack 708 will alternately mesh with the upper and lower ends of the second gear 704, respectively. This causes the second gear 704 to perform intermittent forward and reverse rotation. That is, after the second gear 704 finishes rotating forward, it will pause for a period of time before reversing, and then after the reverse rotation, it will pause for a period of time before rotating forward again, and so on. Then, the second gear 704 will drive the second bevel gear 703 to perform intermittent forward and reverse rotation, the second bevel gear 703 will drive the first bevel gear 702 to perform intermittent forward and reverse rotation, the first bevel gear 702 will drive the first gear 701 to perform intermittent forward and reverse rotation, and then the first gear 701 will drive the scraper mechanism 6 to rotate downwards to lower itself and rotate upwards to retract itself.

[0045] During the above process, when the two electromagnets 4 are closed and lose their magnetism, they still retain a certain amount of magnetism. Therefore, a small amount of iron filings will adhere to the outer surfaces of the two electromagnets 4 and cannot fall off directly. Since the two electromagnets 4 are constantly rotating, the scraper 607 will scrape off the residual iron filings on the outer surfaces of the electromagnets 4. These residual iron filings scraped off by the scraper 607 will eventually be discharged through the discharge port at the lower end of the housing 1 and recycled. Therefore, through the setting of the scraping mechanism, under the action of the scraping mechanism 6 and the rotating collection and dispensing mechanism 7, it is possible to easily scrape off the small amount of residual iron filings on the outer surfaces of the electromagnets 4 when they are closed and lose their magnetism, thus achieving thorough and comprehensive scraping of the outer surfaces of the electromagnets 4. This avoids excessive iron filings remaining on the outer surfaces of the electromagnets 4, which would affect the subsequent iron filings adsorption process and also avoids the waste of iron filings resources. Example

[0046] Reference Figure 8 , Figure 10-11 as well as Figure 16In another preferred embodiment of the present invention, the difference from Embodiment 2 is that a cleaning mechanism is provided on the bracket 601, and the cleaning mechanism is located on the upper surface of the scraper 607. The cleaning mechanism includes a first friction wheel 604, a second friction wheel 605, and a cleaning blade 606. The first friction wheel 604 is rotatably connected to the bracket 601, the second friction wheel 605 is fixedly connected to one end of the electromagnet 4, and the second friction wheel 605 and the first friction wheel 604 are connected by friction transmission. The cleaning blade 606 is rotatably connected to the bracket 601, and the cleaning blade 606... One end of the cleaning mechanism 6 is fixedly connected to the first friction wheel 604. The cleaning blade 606 is located on the upper surface of the scraper 607. When the scraping mechanism 6 falls onto the upper end of the corresponding electromagnet 4, the first friction wheel 604 falls onto the corresponding second friction wheel 605 and makes full contact with it. Since the electromagnet 4 drives the second friction wheel 605 to rotate, the second friction wheel 605 drives the first friction wheel 604 to rotate, and the first friction wheel 604 drives the cleaning blade 606 to rotate. The cleaning blade 606 then cleans the iron filings left on the upper surface of the scraper 607. Therefore, through the arrangement of the cleaning mechanism, the iron filings left on the upper surface of the scraper 607 can be easily cleaned away under the action of the first friction wheel 604, the second friction wheel 605, and the cleaning blade 606. Example

[0047] Reference Figure 8 and Figure 12-13 As another preferred embodiment of the present invention, the difference from embodiment 3 is that a chip removal mechanism is provided at the upper end of the support 601. The chip removal mechanism includes an air duct 602 and an extraction pipe 603. The air duct 602 is fixedly connected to the upper end of the support 601. One end of the extraction pipe 603 is fixedly connected to the air duct 602, and the other end of the extraction pipe 603 extends to the outside of the housing 1. An air pump is connected to the extraction pipe 603, and the other end of the air pump is connected to the recycling box for recycling iron filings through a pipe. When the air pump connected to the extraction pipe 603 is started, the iron filings swept off the upper surface of the scraper 607 will be extracted and sorted and recycled after passing through the air duct 602 and the extraction pipe 603. Therefore, through the setting of the chip extraction mechanism, under the action of the air duct 602 and the extraction pipe 603, the iron chips swept off the upper surface of the scraper 607 can be easily extracted and sorted for recycling. This avoids leaving too many iron chips when the scraper 607 scrapes the electromagnet 4, and can thoroughly clean the remaining iron chips. This not only allows for better separation and sorting of iron chips in the subsequent mixture, but also enables more complete sorting and recycling of iron chips in the mixture, avoiding waste of iron chip resources. Example

[0048] Reference Figure 3-4 , Figure 6 , Figure 12-15 as well as Figure 17 As another preferred embodiment of the present invention, the difference from embodiment 4 is that an isolation mechanism 9 is provided inside the housing 1, and the isolation mechanism 9 is located directly below the crushing device 3 and directly above the electromagnet 4. The isolation mechanism 9 is connected to the third gear 705 through the belt drive 8. The isolation mechanism 9 includes two partitions 901, an opening and closing mechanism, and a touch switch 905. The two partitions 901 are slidably disposed on both sides of the inner wall of the housing 1. The opening and closing mechanism is connected to the two partitions 901 respectively. The opening and closing mechanism is connected to the third gear 705 through the belt drive 8 and is disposed on the outer wall of the housing 1. The touch switch 905 is disposed between the two partitions 901.

[0049] The opening and closing mechanism includes a fifth gear 902, two racks 903, and two connecting rods 904. The fifth gear 902 is rotatably connected to the housing 1 and is connected to the third gear 705 via a belt drive 8. The two racks 903 are slidably disposed on the outer side wall of the housing 1 and are centrally symmetrical about the center of the fifth gear 902. Both racks 903 mesh with the fifth gear 902. One end of each connecting rod 904 is fixedly connected to the opposite end of each rack 903, and the other end is fixedly connected to the opposite end of each partition 901. When the first gear 701 drives the scraping mechanism 6 to rotate downwards, the scraping mechanism 6 will fall onto the upper end of the corresponding electromagnet 4's outer surface. During this process, under the action of the belt drive component 8, the second gear 704 will also drive the fifth gear 902 to perform intermittent forward and reverse rotation. Then, the fifth gear 902 will drive the two spur racks 903 to perform intermittent bidirectional reciprocating motion. Then, under the connection of the two connecting rods 904, it will drive the two partitions 901 to perform intermittent bidirectional reciprocating motion. This allows the two partitions 901 to perform intermittent opening and closing processes. When the two partitions 901 are closed, they will generate a pressure force on the touch switch 905, and the touch switch 905 will control the two electromagnets 4 to close and lose their magnetism. When the two partitions 901 are open, the touch switch 905 will lose its pressure force, and the touch switch 905 will control the two electromagnets 4 to open and generate magnetism.

[0050] Working principle:

[0051] First, in the initial state, the two partitions 901 are fully open, and the two scraping mechanisms 6 are in a retracted, upright position.

[0052] At this time, the mixed material is fed into the shell 1 through the feeding hopper 2. At the same time, the crushing device 3 is turned on to crush the fed mixed material. The crushed mixed material will fall directly. Since the two partitions 901 are in an open and non-contacting state, the touch switch 905 will not be pressed. The touch switch 905 will control the two electromagnets 4 to turn on and generate magnetism. Through the drive device 5, the two electromagnets 4 can be controlled to rotate in opposite directions. The falling crushed mixed material will pass between the two activated electromagnets 4. The two electromagnets 4 will attract the magnetic iron filings in the crushed mixed material and attach them to their outer surface. The remaining non-magnetic, non-iron filings will fall directly through the two electromagnets 4. Finally, the non-magnetic, non-iron filings will be discharged through the discharge port at the lower end of the shell 1. At this time, the non-magnetic, non-iron filings in the fed mixed material can be sorted and recycled.

[0053] Secondly, after the two electromagnets 4 have been running for a period of time, the iron filings adsorbed on their outer surfaces need to be cleaned off to avoid affecting the subsequent sorting and recycling process of the mixed materials. At this time, by starting the motor 710, the motor 710 will drive the sector gear 709 to rotate continuously. The sector gear 709 will drive the fourth gear 707 to rotate intermittently. The fourth gear 707 will drive the second arc-shaped rack 708 to rotate intermittently in the same direction. The fourth gear 707 will also drive the third gear 705 to rotate... The intermittent rotation in the opposite direction causes the third gear 705 to drive the first arc-shaped rack 706 to rotate intermittently in the opposite direction to the second arc-shaped rack 708. Then, the first arc-shaped rack 706 and the second arc-shaped rack 708 will alternately mesh with the upper and lower ends of the second gear 704, respectively. This will cause the second gear 704 to perform intermittent forward and reverse rotation. That is, after the second gear 704 finishes rotating forward, it will pause for a period of time before reversing, and then after the reverse rotation ends, it will pause for a period of time before rotating forward again, and so on.

[0054] Then, the second gear 704 will drive the second bevel gear 703 to perform intermittent forward and reverse rotation, the second bevel gear 703 will drive the first bevel gear 702 to perform intermittent forward and reverse rotation, the first bevel gear 702 will drive the first gear 701 to perform intermittent forward and reverse rotation, and then the first gear 701 will drive the scraper mechanism 6 to rotate downwards to lower itself and rotate upwards to retract itself.

[0055] When the first gear 701 drives the scraper mechanism 6 to rotate downwards and lower itself, the scraper mechanism 6 will fall onto the upper end of the corresponding electromagnet 4's outer surface. During this process, under the action of the belt drive 8, the second gear 704 will also drive the fifth gear 902 to perform intermittent forward and reverse rotation. The fifth gear 902 will then drive the two spur racks 903 to perform intermittent bidirectional reciprocating motion. Under the connection of the two connecting rods 904, this will drive the two partitions 901 to perform intermittent bidirectional reciprocating motion, thus enabling the two partitions 901 to... During the intermittent opening and closing process, the two partitions 901 are gradually closing. The pressure switch 905 loses its pressure force, causing the two electromagnets 4 to close and lose their magnetism. Since the two electromagnets 4 are constantly rotating in opposite directions, the iron filings adsorbed on their outer surfaces lose their attraction and fall directly down. Finally, these iron filings fall through the discharge port at the lower end of the housing 1, allowing for their sorting and recycling.

[0056] Next, during the above process, since the two electromagnets 4 will still retain a certain amount of magnetism when they are closed and lose their magnetism, a small amount of iron filings will still be adsorbed on the outer surface of the two electromagnets 4 and cannot fall off directly. At this time, since the two electromagnets 4 are constantly rotating, the scraper 607 will scrape off the iron filings on the outer surface of the electromagnets 4. The iron filings scraped off by the scraper 607 will eventually be discharged through the discharge port at the lower end of the housing 1 and be sorted and recycled.

[0057] Additionally, when the scraper mechanism 6 falls onto the upper end of the corresponding electromagnet 4's outer surface, the first friction wheel 604 falls onto the corresponding second friction wheel 605 and makes full contact with it. Since the electromagnet 4 drives the second friction wheel 605 to rotate, the second friction wheel 605 drives the first friction wheel 604 to rotate, which in turn drives the cleaning blade 606 to rotate. The cleaning blade 606 then cleans the iron filings remaining on the upper surface of the scraper 607. Simultaneously, the air pump connected to the extraction pipe 603 is activated. Then, through the air duct 602 and the extraction pipe 603, the iron filings cleaned from the upper surface of the scraper 607 are extracted and... The iron filings that fall when the electromagnet 4 is turned off, the residual iron filings scraped off the outer surface of the electromagnet 4 by the scraper 607, and the residual iron filings swept off and extracted from the upper surface of the scraper 607 can all be sorted and recycled into one recycling bin. The non-magnetic, non-iron filings separated from the mixed materials can be sorted and recycled into another recycling bin. Thus, the magnetic iron filings and non-magnetic non-iron filings in the mixed materials can be separated and sorted, and the magnetic iron filings and non-magnetic non-iron filings in the mixed materials can be recycled separately.

[0058] Therefore, based on the above, firstly, by setting up two electromagnets 4 and a driving device 5, when the two electromagnets 4 are turned on, they can attract magnetic iron filings in the mixture. When the two electromagnets 4 are turned off, most of the iron filings attracted to their outer surface will fall off directly. This allows for convenient separation and classification of magnetic iron filings and non-magnetic non-iron filings in the mixture, and facilitates the recycling of these materials. Secondly, by setting up a chip removal mechanism, under the action of the scraping mechanism 6 and the rotating collection and release mechanism 7, a small portion of the iron filings that were attracted and remained on the outer surface of the electromagnets 4 when they are turned off and lose their magnetism can be easily scraped off. This allows for thorough and comprehensive chip removal from the outer surface of the electromagnets 4, preventing chip damage to the surface of the electromagnets 4. Excessive iron filings remaining on the surface can affect the subsequent iron filings adsorption process and also avoid wasting iron filings resources. Specifically, the cleaning mechanism, with the action of the first friction wheel 604, the second friction wheel 605, and the cleaning blade 606, can easily sweep away the iron filings remaining on the surface of the scraper 607. Furthermore, the chip extraction mechanism, with the action of the air duct 602 and the extraction pipe 603, can easily extract and classify the iron filings swept from the surface of the scraper 607, thus preventing excessive iron filings from being left behind by the scraper 607 during the scraping of the electromagnet 4. This comprehensive cleaning of residual iron filings not only better facilitates the separation and classification of iron filings in the subsequent mixture but also ensures more thorough and complete classification and recycling of iron filings in the mixture, preventing the waste of iron filings resources.
