Description
Technical Field
[0001] This invention relates to the field of photoelectric sorting technology, and more specifically to a photoelectric sorting device for construction waste. Background Technology
[0002] Construction waste refers to construction waste generated by human, construction techniques, and natural causes in construction projects, including waste plastics, waste wood, and gravel. This allows photoelectric sorting devices to replace traditional sorting. The photoelectric sorting device uses photoelectric sensors to detect and identify the corresponding construction waste. When the construction waste is reflected back to the photoelectric sensor, the sensor makes a judgment and identifies the attributes of the construction waste based on its color and shape, thereby completing the accurate sorting of the construction waste. In summary, the inventors have found that existing photoelectric sorting devices have the following main drawbacks: Construction waste typically contains scrap iron powder or iron fragments (due to the shortening or deformation of steel bars and iron products during cutting), causing the generated scrap iron powder to come into contact with the surface of waste plastics, waste wood, and gravel. When the scrap iron powder adheres to the surface of the waste, it enters the sorting device along with the waste. This means that while the sorting device performs large-scale sorting of waste plastics, waste wood, and gravel, it cannot remove the scrap iron powder adhering to the surface. After sorting, the scrap iron powder on the surface must be scraped off one by one, thus reducing the sorting efficiency of the device and increasing the sorting time for construction waste. Summary of the Invention
[0003] The technical solution adopted by the present invention to achieve the technical objective is: a photoelectric sorting device for construction waste, the structure of which includes: a base, a support column, a conveyor body, a light energy detector, a push-out structure, and a guide plate. The two sides of the surface edge of the base are perpendicular to each other with the support column. The top of the support column is fixedly connected to the lower edge of the conveyor body. The light energy detector is set in the upper area of the conveyor body. The push-out structure is embedded in the surface edge of the conveyor body. The guide plate is set in the opposite position of the push-out structure and communicates with the conveyor body. The bottom of the guide plate is in contact with the surface of the base.

The slide rod of the slot of the vibration component is electrically connected to the power block of the motion module. The slot is circular. The surface of the limiting frame and the connecting plate is flattened. The area of the parallel module is the same as the area of the connecting plate. The vibration component covers the lower layer of the planar adsorption block. The triangular adsorption blocks are arranged symmetrically on both sides of the surface of the planar adsorption block.
[0006] As a further improvement of the present invention, the vibration assembly includes protrusions, a connecting body, a superimposed plate, a vibration rod, and a disassembly / assembly body. The protrusions are welded to the surface area of the connecting body and are perpendicular to each other. The connecting body is located at the edge area of the superimposed plate. The vibration rod is embedded in the inner area of the superimposed plate. The disassembly / assembly body is engaged with the vibration rod and installed on the outer edge area of the superimposed plate. The vibration rod is attached to the lower layer of the planar adsorption block through the superimposed plate. The disassembly / assembly body is located on the outer edge area of the parallel module through the superimposed plate and is clearance-fitted. The connecting body is equipped with multiple square protrusions. There are two sets of connecting bodies on the superimposed plate. Multiple vibration rods are provided on the surface of the superimposed plate, which are arranged in a crisscross pattern to cover the surface of the superimposed plate. The number of disassembly / assembly bodies is the same as the number of vibration rods. Each set of disassembly / assembly bodies can only be connected to a single vibration rod.
[0007] As a further improvement of the present invention, the disassembly body is provided with a through groove, a lever, a straight rod, a thin reinforcing frame, and a covering cavity. The through groove extends through both sides of the surface of the lever. The two sides of the lever's side end are welded to the straight rod. The thin reinforcing frame is embedded in the center of the lever's side end and is spaced to fit the straight rod. The covering cavity is opened in the internal area of the thin reinforcing frame. The lever is installed on the edge of the composite plate through the straight rod. The thin reinforcing frame is connected to the vibration rod through the covering cavity. There are two through grooves on the lever. Two straight rods are welded to the side end of the lever. The thickness of the thin reinforcing frame is [thickness value missing]. The shape of the covering cavity is consistent with that of the thin reinforcing frame.
[0008] As a further improvement of the present invention, the photodetector is provided with a detection body, a positioning plate, a penetration groove, a dustproof component, and a mating cavity. The detection body is embedded in the center of the surface of the positioning plate. The positioning plate coincides with the penetration groove. The top of the dustproof component and the penetration groove are integrated. The mating cavity runs through the central area of the dustproof component and communicates with the detection body through the penetration groove. The detection body communicates with the conveyor through the mating cavity. The detection body is provided with four sets on the positioning plate. The length of the positioning plate is the same as the length of the penetration groove. The dustproof component is made of stainless steel on the outside, but the inner layer is covered by a rubber component.
[0009] As a further improvement of the present invention, the detection body is provided with a transparent light mirror, a light energy receiving module, an information reaction disk, and a power supply component. The inner center of the transparent light mirror is fixedly connected to the light energy receiving module. The light energy receiving module is embedded in the central area of the information reaction disk and electrically connected. The power supply component is fixedly connected to the information reaction disk. The transparent light mirror is attached to the information reaction disk through the light energy receiving module. The transparent light mirror and the light energy receiving module pass through the surface of the positioning plate and communicate with the penetration groove and the mating cavity. The surface of the transparent light mirror is finely polished, the light energy receiving module is cylindrical, and the diameter of the information reaction disk is smaller than that of the transparent light mirror.
[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. With further improvements to the ejection structure, the anti-detachment block at the bottom of the slide bar can effectively prevent detachment caused by sliding on the motion module. At the same time, with the support of the vibration adsorption body, the vibration component, triangular adsorption block and planar adsorption block can effectively shake off the waste iron powder on the surface of different construction wastes and then adsorb and collect it. This can effectively solve the problem of having to scrape the surface of each construction waste one by one due to the adhesion of iron powder, and improve the usage intensity of the sorting device.
[0011] 2. With further improvements to the vibration component, this invention effectively arranges multiple vibration rods in a cross pattern by using the overlapping base of the overlapping plate and parallel modules. This ensures that the vibration rods completely cover the bottom layer of the planar adsorption block, guaranteeing the completeness of the vibration and preventing omissions caused by the lack of vibration at the edges. Furthermore, the disassembly and assembly parts on the vibration rods can improve the vibration force of the vibration rods through a thin reinforcing frame, and the use of the lever blocks can improve the convenience of removing the vibration rods from the overlapping plate area for maintenance.
[0012] 3. This invention further improves upon the optical energy detector by using a positioning plate to forcibly limit the positions of multiple detection bodies, ensuring that the detection bodies are located on the same horizontal straight line. This prevents the reduction in detection accuracy of construction waste on the conveyor body caused by offset. At the same time, the dustproof component effectively prevents the outward overflow of iron powder during the processing of construction waste, improving the completeness of iron powder collection. Furthermore, the newly added transparent light mirror at the lower end of the detection body improves the light source reception effect. Simultaneously, the transparent light mirror effectively prevents iron powder from entering the information reaction disk, ensuring the normal operation of the information reaction disk.

[0021] The present invention will be further described below with reference to the accompanying drawings: Example
[0022] Figures 1 to 5 As shown: This invention provides a photoelectric sorting device for construction waste. Its structure includes a base 1, a support column 2, a conveyor body 3, a light energy detector 4, an ejection structure 5, and an ejection slide plate 6. The two sides of the surface edge of the base 1 are perpendicular to the support column 2. The top of the support column 2 is fixedly connected to the lower edge of the conveyor body 3. The light energy detector 4 is located in the upper area of the conveyor body 3. The ejection structure 5 is embedded in the surface edge of the conveyor body 3. The ejection slide plate 6 is located opposite the ejection structure 5 and communicates with the conveyor body 3. The bottom of the ejection slide plate 6 is in contact with the surface of the base 1.
[0023] The ejection structure 5 includes a power block 51, a motion module 52, a slide bar 53, an anti-detachment block 54, and a vibration adsorption body 55. The power block 51 is embedded in the surface area of the motion module 52. The slide bar 53 passes through the central area of the motion module 52 and fits against it. The anti-detachment block 54 is welded to the bottom of the slide bar 53. The vibration adsorption body 55 is located in the opposite area of the anti-detachment block 54 and is engaged with the top of the slide bar 53. The vibration adsorption body 55 communicates with the internal area of the conveyor body 3 through the slide bar 53. The motion module 52 has a built-in linear slide rail and multiple ball bearings. The slide bar 53 is made of metal with a finely polished surface. The anti-detachment block 54 has rounded corners and is perpendicular to the slide bar 53. The vibration adsorption body 55 is solid. The linear guide rail and ball bearings built into the motion module 52 help the slide rod 53 move in a straight line, improving the smoothness of the slide rod 53. The slide rod 53 is reinforced with metal products to extend its service life and prevent deformation. At the same time, fine polishing can prevent jamming. The anti-detachment block 54 has rounded corners to prevent scratches caused by workers adjusting the slide rod 53. The vibration adsorption body 55 is solid and can push out construction waste while collecting the iron powder attached to its surface.
[0024] The vibrating adsorption body 55 includes a slot 551, a limiting frame 552, a connecting plate 553, a parallel module 554, a vibration component 555, a triangular adsorption block 556, and a planar adsorption block 557. The slot 551 passes through the central area of the connecting plate 553 via the limiting frame 552. The limiting frame 552 and the connecting plate 553 are on the same horizontal line. The lower layer of the parallel module 554 is attached to the connecting plate 553 and communicates with the slot 551. The vibration component 555 is distributed in the internal area of the parallel module 554. The triangular adsorption block 556 is embedded in the top edge of the parallel module 554. The planar adsorption block 557 is installed on the flat surface. The surface of the parallel module 554 is connected to the triangular adsorption block 556. The parallel adsorption block 557 and the triangular adsorption block 556 are both connected to the vibration component 555 through the parallel module 554. The slide rod 53 of the slot 551 of the vibration component 555 is electrically connected to the power block 51 of the motion module 52. The slot 551 is circular. The surface of the limiting frame 552 and the connecting plate 553 is flat. The area of the parallel module 554 is the same as the area of the connecting plate 553. The vibration component 555 covers the lower layer of the planar adsorption block 557. The triangular adsorption blocks 556 are arranged symmetrically on both sides of the surface of the planar adsorption block 557. The slot 551, with its circular shape, can be adapted to the shape of the component. The limiting frame 552 and the connecting plate 553 can achieve stable overlapping splicing by using surface flattening and consistent area, thus preventing tilting after overlapping. The vibration component 555, through the cover of the planar adsorption block 557, can drive the entire planar module 557 to perform omnidirectional vibration operation. The number and shape of the triangular adsorption blocks 556 can penetrate the bottom of the construction waste and then push it out, thereby collecting the scrap iron powder at the edge of the construction waste.
[0025] The vibration assembly 555 includes a protrusion a1, a connector a2, a superimposed plate a3, a vibration rod a4, and a disassembly / assembly body a5. The protrusion a1 is welded to the surface area of the connector a2 and is perpendicular to each other. The connector a2 is located at the edge area of the superimposed plate a3. The vibration rod a4 is embedded in the inner area of the superimposed plate a3. The disassembly / assembly body a5 is engaged with the vibration rod a4 and installed on the outer edge area of the superimposed plate a3. The vibration rod a4 is connected to the lower layer of the planar adsorption block 557 through the superimposed plate a3. The disassembly body a5 is fitted together with the overlapping plate a3 and is set on the outer edge area of the parallel module 554 with clearance fit; the connecting body a2 is equipped with multiple square protrusions a1, and there are two sets of connecting bodies a2 on the overlapping plate a3. Multiple vibration rods a4 are provided on the surface of the overlapping plate a3, which are arranged in a cross shape to cover the surface of the overlapping plate a3. The number of disassembly bodies a5 is the same as the number of vibration rods a4, and each set of disassembly bodies a5 can only be connected to a single vibration rod a4. The connecting body a2, equipped with protrusions a1, allows the overlapping plate a3 to be stably spliced with the component. The multiple vibration rods a4 on the overlapping plate a3, arranged in a cross pattern, effectively avoid the generation of vibration dead zones and ensure that the edges of the component are controlled by vibration force. The disassembly body a5, with the same number as the vibration rods a4, allows for the adjustment of individual vibration rods a4, avoiding the need to disassemble the entire unit if a single vibration rod a4 fails.
[0026] The disassembly / assembly body a5 includes a through groove a51, a lever a52, a straight rod a53, a thin reinforcing frame a54, and a covering cavity a55. The through groove a51 extends through both sides of the surface of the lever a52. The two sides of the lever a52 are welded to the straight rod a53. The thin reinforcing frame a54 is embedded in the center of the side end of the lever a52 and is spaced to fit the straight rod a53. The covering cavity a55 is opened in the internal area of the thin reinforcing frame a54. The lever a52 is installed on the edge of the composite plate a3 through the straight rod a53. The thin reinforcing frame a54 is connected to the vibration rod a4 through the covering cavity a55. There are two through grooves a51 on the lever a52. Two straight rods a53 are welded to the side end of the lever a52. The thickness of the thin reinforcing frame a54 is 3mm. The shape of the covering cavity a55 is consistent with that of the thin reinforcing frame a54. The through groove a51, based on the two foundations on the lever a52, can improve the control effect of the lever a52. The two straight rods a53 welded to the side of the lever a52 can ensure that the lever a52 can be overlapped and spliced with the component through the straight rods a53. The thin and light reinforcing frame a54, based on its own thickness, can effectively separate the intersecting components and utilize the characteristics of the "vibration plate" to increase the vibration force of the component.
[0027] The specific functions and operation procedures of this embodiment are as follows: In this invention, First: The photoelectric sorting device for construction waste can effectively fix the position of the conveyor body 3 through the base 1 and the support column 2. After the conveyor body 3 is connected to the external power supply, the connected photoelectric detector 4 and the ejection structure 5 can be activated to start operation. After the construction waste is put into the area of the conveyor body 3, it is transported by the conveyor body 3. During the process, the photoelectric detector 4 uses photoelectric sensing characteristics to determine the different categories of construction waste based on its shape and reflected light beam. With the support of the photoelectric detector 4, the ejection structure 5 can eject waste plastic, waste wood, gravel and other objects one by one. Finally, the objects ejected by the ejection structure 5 can slide out through the ejection slide plate 6. With the precise cooperation of the photoelectric detector 4 and the ejection structure 5, the types of construction waste can be sorted quickly. Second: The motion module 52 of the structure 5 can be electrically connected to the conveyor 3 using the power block 51. When the motion module 52 is positioned at the edge of the conveyor 3, it can assist the slide bar 53 in linear motion through the built-in slide rail and ball bearings, enhancing the smoothness of the slide bar 53. The anti-detachment block 54 at the lower end of the slide bar 53 can prevent the slide bar 53 from slipping out excessively and falling off by its own length. At the same time, the slide bar 53 can contact the construction waste using the vibration adsorption body 55 at the top. With the support of the vibration adsorption characteristics, the construction waste will be affected by the vibration force after contacting it, and the iron powder attached to it will be shaken off. After the iron powder is shaken off, it will be attracted by magnetic attraction, thereby completing the separation of construction waste and iron powder. This prevents the need to scrape off the iron powder on the surface of the construction waste one by one after sorting, thereby improving the use intensity of the sorting equipment. Third: The vibrating adsorption body 55 can be spliced with the top of the slide bar 53 through the slot 551 in the central area of the limiting frame 552 of the connecting plate 553. After the connecting plate 553 and the lower layer of the parallel module 554 are integrated, the slide bar 53 will control the parallel module 554 through the connection with the slot 551. This allows the internal vibrating component 555, the surface triangular adsorption block 556, and the planar adsorption block 557 of the parallel module 554 to move through the sliding of the slide bar 53. When the parallel module 554 comes into contact with the construction waste, it first inserts the bottom of the construction waste through the triangular adsorption block 556 on the surface edge, so that the construction waste can make full contact with the planar adsorption block 557. Then, under the influence of the vibration force of the vibrating component 555, the waste iron powder on the surface of the construction waste can be shaken off. Then, the magnetic attraction characteristics of the triangular adsorption block 556 and the planar adsorption block 557 are used to receive the waste iron powder, thus completing the separation of the waste iron powder from the construction waste. Fourth: The vibration component 555 can effectively connect with the bottom layer of the planar adsorption block 557 through the cooperation of the connecting body a2 at the upper and lower ends of the composite plate a3 and the protrusion a1. Thus, the multiple vibration rods a4 arranged on the composite plate a3 will be arranged in a cross manner, so that the bottom layer of the planar adsorption block 557 will be fully covered by the vibration rods a4. This can improve the integrity of the planar adsorption block 557 in processing construction waste and prevent the scrap iron powder at the edge of the construction waste from not being properly processed due to the lack of vibration characteristics at the corners. At the same time, the multiple sets of disassembly parts a5 on the edge of the composite plate a3 can be spliced with each vibration rod a4 one by one according to their own quantity. If a single vibration rod a4 fails, the faulty vibration rod a4 can be removed through the disassembly body a5, thus preventing the need to completely disassemble the component for a single failure and improving the convenience of component maintenance. Fifth: The lever a52 of the disassembly body a5 will be pulled by the operator through the through slot a51, so that the two straight rods a53 on the side of the lever a52 can be inserted into the edge of the overlapping plate a3 to complete the connection. For this purpose, the thin reinforcing frame a54 on the side of the straight rod a53 can cover the vibrating rod a4 with its own 3mm thickness and the covering cavity a55. Thus, the multiple sets of vibrating rods a4 can be separated by the thin reinforcing frame a54 to prevent damage caused by continuous mutual impact of the main body. Furthermore, the thin reinforcing frame a54 can improve the vibration intensity of the vibrating rod a4 by utilizing the characteristics of the "vibrating plate", so as to enhance the processing efficiency of the surface waste iron powder of construction waste. Example
[0028] Figures 6 to 7 As shown: This invention provides a photoelectric sorting device for construction waste. Its structure includes: the photodetector 4 is provided with a detection body 41, a positioning plate 42, a penetration groove 43, a dustproof component 44, and a mating cavity 45. The detection body 41 is embedded in the center of the surface of the positioning plate 42. The positioning plate 42 coincides with the penetration groove 43. The top of the dustproof component 44 is an integral structure with the penetration groove 43. The mating cavity 45 passes through the central area of the dustproof component 44 and communicates with the detection body 41 through the penetration groove 43. The detection body 41 communicates with the conveyor 3 through the mating cavity 45. There are four sets of detection bodies 41 on the positioning plate 42. The length of the positioning plate 42 is the same as the length of the penetration groove 43. The dustproof component 44 is made of stainless steel on the outside, but the inner layer is covered with rubber. The detection body 41 can automatically identify the type of construction waste by measuring the quantity on the positioning plate 42. The length of the positioning plate 42 can be used to position the detection body 41 on top of the dustproof component 44 with the support of the through groove 43. The dustproof component 44 can improve its own use effect through its external anti-rust properties, and the internal rubber parts can prevent mutual traction with the adsorption components, ensuring the stable operation of each component. At the same time, its own covering characteristics can prevent iron powder from overflowing during the sorting process.
[0029] The detection body 41 includes a transparent light mirror 411, a light energy receiving module 412, an information reaction disk 413, and a power supply component 414. The inner center of the transparent light mirror 411 is fixedly connected to the light energy receiving module 412. The light energy receiving module 412 is embedded in the central area of the information reaction disk 413 and electrically connected. The power supply component 414 is fixedly connected to the information reaction disk 413. The transparent light mirror 411 is attached to the information reaction disk 413 through the light energy receiving module 412. The transparent light mirror 411 and the light energy receiving module 412 penetrate the surface of the positioning plate 42 and communicate with the penetration groove 43 and the mating cavity 45. The surface of the transparent light mirror 411 is finely polished, the light energy receiving module 412 is cylindrical, and the diameter of the information reaction disk 413 is smaller than that of the transparent light mirror 411. The transparent light mirror 411, through its finely polished shape, can prevent iron powder residue from the rough surface and its impact on the reception of the light source. The light energy receiving module 412, with its cylindrical shape, can install the transparent light mirror 411 on the lower layer of the information reaction disk 413. Thus, the information reaction disk 413 can be used with the support of the transparent light mirror 411, preventing iron powder from intruding into the interior of the information reaction disk 413 due to contact with iron powder.
[0030] The specific functions and operation procedures of this embodiment are as follows: In this invention, First: The multiple detection bodies 41 of the light energy detector 4 are positioned on the same straight line by the positioning plate 42, so that the positioning plate 42 can fix the detection body 41 to the top of the dustproof part 44 by the through groove 43. After the detection body 41 and the mating cavity 45 inside the dustproof part 44 are connected, the construction waste transported by the conveyor 3 can be clearly identified. Then, based on the fact that the detection body 41 is on the same straight line, the position deviation can be prevented from reducing the sensing accuracy. At the same time, the dustproof part 44 can effectively prevent the external airflow generated by the vibration adsorption body 55 during the treatment of waste iron powder of construction waste from affecting the treatment process, and improve the adsorption stability of waste iron powder. Then, the dustproof part 44 can replace the conveyor 3 and connect to the ejection structure 5 by the snap-fit connection between the dustproof part 44 and the edge of the conveyor 3, thereby reducing the weight of the conveyor 3. When there is too much waste iron powder on the ejection structure 5, it can be removed by the dustproof part 44 from the conveyor 3, thereby completing the treatment of waste iron powder on the ejection structure 5. Second: The energizing component 414 of the detection body 41 will be electrically connected to the conveyor body 3 through a corresponding spool. Thus, the information reaction disk 413 can perform photoelectric sensing operations with the power of the energizing component 414. The newly added light energy receiving module 412 and transparent light mirror 411 at the lower end of the information reaction disk 413 can improve the accuracy of receiving and judging the reflected light source. Then, the isolation of the transparent light mirror 411 can effectively prevent the impact of the intrusion of waste iron powder into the information reaction disk 413, ensuring the stable operation performance of the information reaction disk 413. Furthermore, the fixed-point reception of the light energy receiving module 412 can enhance the accuracy of the information reaction disk 413 in identifying the type of construction waste.
