Description

Technical Field

[0001] This invention relates to the field of material screening technology, specifically to an infrared automatic separator suitable for the feed inlet. Background Technology

[0002] Infrared screening automatic separators suitable for the feed inlet typically refer to those that use infrared technology to detect materials before they enter the processing equipment through the feed inlet, and then activate the screen plate to screen and separate the materials. Before the materials enter the processing equipment through the feed inlet, they can effectively remove materials that do not meet the requirements, ensuring the smooth progress of subsequent processing. In the field of screening technology, screen plates are key equipment, and their performance and condition directly affect the efficiency of screening operations, product quality, and the overall stability of the production line. However, for a long time, screen plates have been prone to dents or damage to their surface holes during operation due to factors such as material impact and vibration fatigue. As the screen plates are running, operators cannot detect the abnormalities in the screen holes in time. This not only causes the size and shape of the materials screened by the screen plate to no longer meet the design requirements, resulting in poor material throughput and some fine particles being unable to pass through the screen holes, thus reducing screening efficiency, but also, if the screen holes are not repaired in time after dents occur, the screen holes will further enlarge and deteriorate over time, thereby reducing the service life of the screen plate and increasing the maintenance cost of the screen plate. Secondly, to prevent material from accumulating on the screen plate, a material-distributing function is usually used to move the material on the screen plate. However, the current material-distributing path is generally a horizontal straight back-and-forth motion, which is relatively simple. The horizontal straight back-and-forth motion not only fails to fully cover all areas of the screen plate, resulting in some areas of material not being effectively moved, thus affecting the uniform distribution of the material, but also makes it easier for material to accumulate in some areas due to the simple material-distributing path. This accumulation phenomenon is more obvious when the material has high moisture content or uneven particle size. The accumulated material will directly cover the screen holes, causing the screen holes to become blocked.

[0003] Therefore, this invention proposes an infrared screening automatic separator suitable for the feed inlet to solve the above problems. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an infrared automatic screening separator suitable for the feed inlet, which can effectively solve the problem that workers cannot detect dents and damage to the screen holes in a timely manner during the operation of the screen plate.

[0012] As a further aspect of the present invention: a second corrugated plate is fixedly connected to the lower end face of the first corrugated plate. The first and second corrugated plates have the same wave crests, but the wave crest spacing of the first and second corrugated plates is different.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides an automatic infrared screening separator suitable for the feed inlet, which has the following advantages: 1. Through the set screen hole abnormality detection mechanism, during the operation of the vibrating screen plate, the detection rod can be driven to move against the surface of the vibrating screen plate and contact the screen hole. When the detection rod moves to the screen hole where there is a dent or damage, it will automatically descend and trigger the warning light to flash. This real-time monitoring function not only reduces the decline in screening efficiency or product quality problems caused by screen hole problems, ensuring the stability and reliability of the production process, but also timely detection and repair of screen hole problems can prevent the problem from further expanding and deteriorating, thereby reducing the complexity and cost of maintenance work. In addition, through regular monitoring and preventive maintenance, the service life of the screen plate can be extended and the overall maintenance cost can be reduced. By setting the lower end of the detection rod to a spherical surface, when the detection rod detects dents or damage on the surface of the vibrating screen plate, the spherical surface can more easily slide over these areas, preventing the detection rod from being damaged due to jamming or affecting the normal operation of screening. Moreover, the spherical surface can better adapt to various shapes and minor changes on the surface of the screen plate, ensuring the accuracy of the detection results. In addition, the spherical design reduces the direct contact area between the detection rod and the vibrating screen plate, thereby reducing wear caused by friction and extending the service life of the detection rod and the vibrating screen plate. Furthermore, in the existing technology, a vibrating motor is used to drive the vibrating screen plate to perform reciprocating vibration. When the vibration force and kinetic energy generated during the screening process directly act on the vibrating screen plate itself, it is easy to cause local stress concentration, which in turn leads to fatigue and damage of the components. By connecting the vibrating screen plate to the horizontal plate through the connecting column, the horizontal plate can effectively disperse the force generated by the vibrating screen plate during the screening process and convert the kinetic energy generated by the vibrating screen plate, reducing the load on individual components. This not only enhances the stability of the entire structure but also avoids stress concentration on the vibrating screen plate, preventing component damage caused by excessive stress, thereby extending the service life of the vibrating screen plate. Finally, by meshing the rack and pinion plates and the transmission gears, the kinetic energy of the vibrating screen plate can be converted into the rotational kinetic energy of the shaft, driving the shaft to rotate back and forth. This causes the moving plate to move the detection rod horizontally back and forth on the surface of the vibrating screen plate. This not only reduces energy loss during transmission, but also improves the overall system's energy utilization efficiency. Furthermore, the automatic reciprocating movement mechanism of the moving plate does not require an external power source and is driven entirely by the vibration energy of the vibrating screen plate itself, thus reducing the system's complexity and energy consumption. Secondly, in the existing technology, the material above the vibrating screen plate is generally moved horizontally in a straight line. Therefore, when screening different materials, the way the material is moved is the same. By setting a moving limit mechanism, the horizontal movement trajectory of the detection rod can be changed during the horizontal movement of the moving plate. This not only allows for quick adjustment and optimization according to actual needs and screening conditions, improving the adaptability and flexibility of screening operations, but also ensures that the detection rod can cover more areas on the vibrating screen plate, even hard-to-reach corners, thereby achieving more comprehensive monitoring of the screen holes and material status. In this process, the linkage rod contacts the crest of the first corrugated plate during the horizontal movement of the moving plate, which changes the horizontal movement trajectory of the moving plate and the detection rod. This makes the movement no longer limited to a straight line, but rather has a certain degree of shaking and curvilinear movement. This helps to more comprehensively detect the dents or damage on the surface of the screen plate, and to move the material more evenly, reducing the phenomenon of missed screening and clogging. Moreover, the shaking effect and trajectory change can promote the flow and dispersion of materials on the vibrating screen plate, reduce the clogging and residence time of materials at the screen holes, and improve screening efficiency.

[0016] 2. The rotating shaft drives the paddle plate and cylindrical moving frame to move horizontally back and forth on the side wall of the material inlet. This drives the moving plate to move the detection rod horizontally back and forth on the surface of the vibrating screen plate. This not only ensures that the movement path of the detection rod covers all the screen holes on the vibrating screen plate, ensuring that each screen hole can be monitored in a timely manner and improving the detection range of the detection rod, but also allows the detection rod to move the material being screened on the upper surface of the vibrating screen plate, preventing the material from accumulating in certain areas of the vibrating screen plate. This ensures that the material is evenly distributed on the vibrating screen plate, reducing the risk of screen hole blockage and improving screening efficiency.

[0017] 3. By changing the contact between the linkage rod and different corrugated plates, the movement path of the detection rod on the material above the vibrating screen plate can be increased. The increased movement path of the detection rod can not only cover and move a larger area of ​​material on the vibrating screen plate, thus ensuring a more uniform distribution of material on the entire screen plate, reducing material accumulation in certain areas and improving screening efficiency, but also, by changing the contact method between the linkage rod and the corrugated plate, the movement path of the detection rod becomes more complex, which can reduce or eliminate blind spots in material movement above the vibrating screen plate and ensure the comprehensiveness of the screening process. The alternating action of the first and second corrugated plates causes the moving plate to experience two swaying motions of different amplitudes during horizontal movement, forming a multi-stage swaying motion. This not only allows the detection rod to more comprehensively cover the surface of the screen plate, further promoting the uniform distribution and screening of materials and reducing screening errors and blockages, but also increases the movement path of the detection rod during horizontal reciprocating movement, making the screening more detailed and comprehensive. Furthermore, by changing the design parameters of the first and second corrugated plates, such as the peak spacing and waveform, multiple working modes can be achieved to adapt to different screening scenarios and material characteristics. Finally, by connecting the two lifting plates with a connecting plate, one lifting plate can drive the other lifting plate to move synchronously during its movement, pushing upwards from both sides below the first and second corrugated plates simultaneously. This reduces the overall structural imbalance caused by uneven movement or deviation of individual components, and ensures the stability and accuracy of the first and second corrugated plates during long-term operation.

[0018] 4. During the long-term operation of the vibrating screen plate, when the screen holes on the surface become concave, different shapes will be produced, such as transverse concave and longitudinal concave. By setting the first and second corrugated plates, the longitudinal movement of the detection rod can be increased during the transverse movement of the detection rod to detect the screen holes, so that it can more comprehensively cover all corners and edges of the screen holes, discover and identify concave in different shapes and directions in the screen holes, and further improve the accuracy and comprehensiveness of the detection.

[0022] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] This embodiment is applicable to the infrared screening automatic separator at the feed inlet, such as... Figure 1 - Figure 9As shown, it includes a feeding inlet 1, and a vibrating screen plate 2 is slidably connected to the upper end of the feeding inlet 1. A screen hole abnormality detection mechanism is provided between the vibrating screen plate 2 and the feeding inlet 1. The screen hole abnormality detection mechanism is used to detect the screen holes on the surface of the vibrating screen plate 2.

[0024] In this embodiment, as Figure 2 As shown, the sieve hole abnormality detection mechanism includes symmetrically arranged connecting columns 305. The connecting columns 305 are all slidably connected to the material inlet 1. The lower ends of the connecting columns 305 are all fixedly connected to the upper end face of the vibrating screen plate 2. The upper ends of the connecting columns 305 are all fixedly connected to the horizontal plates 301. The horizontal plates 301 are all provided with through grooves 304. The moving plates 303 are slidably connected between the through grooves 304. The center of the moving plates 303 is equidistantly connected to the detection rods 306. The lower ends of the detection rods 306 are all attached to the upper end face of the vibrating screen plate 2. The lower ends of the detection rods 306 are all spherical. When the moving plates 303 slide back and forth in the through grooves 304, they can drive the detection rods 306 to move back and forth against the surface of the vibrating screen plate 2.

[0025] In this embodiment, as Figure 2 As shown, each detection rod 306 is fixedly connected to a limiting plate 307 at its upper end. Each limiting plate 307 is equipped with a button 308 below it. Each button 308 is fixedly connected to the upper surface of the moving plate 303. Each button 308 is electrically connected to a warning light 309. Each warning light 309 is fixedly connected to the side wall of the moving plate 303. When the detection rod 306 is dented or damaged, the detection rod 306 will descend on the moving plate 303, causing the limiting plate 307 connected to the upper surface to press the button 308, triggering the warning light 309 to work.

[0026] In this embodiment, as Figure 1 and Figure 6 As shown, the lower end face of the movable plate 303 is symmetrically provided with a sliding groove 315. A movable frame 302 is slidably connected in the sliding groove 315. The movable frame 302 is horizontally slidably connected to the side wall of the feeding inlet 1. During the shaking of the movable plate 303, the movable frame 302 connected to the lower end face of the movable plate 303 will slide in the sliding groove 315 provided in the lower end face of the movable plate 303, so that the movable frame 302 can adapt to the movement of the movable plate 303. As the movable frame 302 moves horizontally, it can move the movable plate 303 synchronously through the sliding groove 315.

[0027] In this embodiment, as Figure 4As shown, cylinders 313 are slidably connected inside the movable frame 302. A lever 312 is fixedly connected to one end of each cylinder 313. A rotating shaft 310 is fixedly connected between the ends of the lever 312 away from the cylinder 313. The rotating shaft 310 is rotatably connected to the feeding inlet 1. When the rotating shaft 310 rotates, the lever 312 can move the cylinder 313 to slide back and forth inside the movable frame 302, so that the movable frame 302 moves horizontally back and forth on the side wall of the feeding inlet 1 following the cylinder 313.

[0028] In this embodiment, as Figure 5 As shown, a transmission gear 311 is fixedly connected to the outer surface of the rotating shaft 310. A rack plate 314 is meshed with one side of the transmission gear 311. The upper end of the rack plate 314 is fixedly connected to the side wall of one of the horizontal plates 301. During the up-and-down movement of the horizontal plate 301, the rack plate 314 and the transmission gear 311 mesh with each other, which can drive the rotating shaft 310 to reciprocate.

[0029] In existing technologies, during the operation of the screen plate, operators cannot detect abnormalities in the screen holes in a timely manner. This not only causes the size and shape of the materials screened by the screen plate to no longer meet design requirements, resulting in poor material throughput and some fine particles being unable to pass through the screen holes, thus reducing screening efficiency, but also, if the screen holes are not repaired in time after they become dented, they will further enlarge and deteriorate over time, thereby reducing the service life of the screen plate and increasing its maintenance costs. Compared with existing technologies, during the operation of the vibrating screen plate 2, the detection rod 306 can be driven to fit against the vibrating screen. When the surface of plate 2 moves and comes into contact with the screen holes, the detection rod 306 will automatically descend when it moves to the screen hole where there is a dent or damage, triggering the warning light 309 to flash. This real-time monitoring function not only reduces the decrease in screening efficiency or product quality problems caused by screen hole problems, ensuring the stability and reliability of the production process, but also allows for timely detection and repair of screen hole problems, preventing further expansion and deterioration of the problem, thereby reducing the complexity and cost of maintenance work. In addition, through regular monitoring and preventive maintenance, the service life of the screen plate can be extended, reducing the overall maintenance cost.

[0030] At other levels, this embodiment also provides a moving limiting mechanism for changing the detection trajectory of the sieve aperture, such as... Figure 1 , Figure 7 - Figure 9 As shown, the moving limiting mechanism includes symmetrically arranged support blocks 411. Each support block 411 has a linkage rod 410 fixedly connected to one side opposite to the other. The end of the linkage rod 410 away from the support block 411 is attached to a first corrugated plate 401.

[0031] In this embodiment, as Figure 8 and Figure 9As shown, a second corrugated plate 403 is fixedly connected to the lower end face of the first corrugated plate 401. The first corrugated plate 401 and the second corrugated plate 403 have the same corrugation peaks, but the spacing between the corrugation peaks of the first corrugated plate 401 and the second corrugated plate 403 is different. A connecting frame 404 is fixedly connected between the two sides of the first corrugated plate 401 and the second corrugated plate 403. A support plate 402 is sleeved on the outside of the connecting frame 404. The support plate 402 is fixedly connected to the upper end face of the horizontal plate 301. A vertical groove 407 is opened on the support plate 402. The connecting frame 404 is slidably connected in the vertical groove 407. When the connecting frame 404 slides up and down in the vertical groove 407, it can change the height of the first corrugated plate 401 and the second corrugated plate 403, so that the different corrugated plates and the linkage rod 410 come into contact.

[0032] In this embodiment, as Figure 9 As shown, each of the lower ends of the connecting frame 404 is fixedly connected to a sliding column 408. The sliding columns 408 are vertically slidably connected to the support plate 402 and the horizontal plate 301. The lower ends of the sliding columns 408 are attached to the lifting plates 409. A connecting plate 405 is fixedly connected between the lifting plates 409 on the same side. The connecting plate 405 and the lifting plates 409 are horizontally slidably connected inside the horizontal plate 301. When the lifting plate 409 moves close to the sliding column 408, it can push the sliding column 408 to slide out from inside the horizontal plate 301, causing the connecting frame 404 to rise. When the lifting plate 409 moves away from the sliding column 408, it will automatically descend due to the influence of the weight of the sliding column 408 and the connecting frame 404.

[0033] In this embodiment, as Figure 8 and Figure 9 As shown, each of the lifting plates 409 on the same side is fixedly connected to a fixed column 406 on the opposite side. The fixed columns 406 are horizontally slidably connected to the horizontal plate 301, and the ends of the fixed columns 406 away from the lifting plates 409 are located in the through grooves 304. When one of the fixed columns 406 is pushed and slides from the through grooves 304 into the horizontal plate 301, it will drive one of the lifting plates 409 to move horizontally, and pull the other lifting plate 409 to move synchronously through the connecting plate 405. This allows the other lifting plate 409 to drive the other fixed column 406 to slide from the horizontal plate 301 into the through grooves 304, so that the other fixed column 406 can be pushed again, changing the position of the lifting plate 409 and the connecting plate 405.

[0034] Compared with the existing technology, the ability to change the horizontal movement trajectory of the detection rod 306 during the horizontal movement of the moving plate 303 can not only be quickly adjusted and optimized according to actual needs and screening conditions, improving the adaptability and flexibility of screening operations, but also ensure that the detection rod 306 can cover more areas on the vibrating screen plate 2, even hard-to-reach corners, thereby achieving more comprehensive monitoring of the screen holes and material status. By changing the contact between the linkage rod 410 and different corrugated plates, the movement path of the detection rod 306 on the material above the reciprocating vibrating screen plate 2 can be increased. The increased movement path of the detection rod 306 can not only cover and move a larger area of ​​material on the vibrating screen plate 2, thereby ensuring a more uniform distribution of material on the entire screen plate, reducing material accumulation in certain areas and improving screening efficiency, but also, by changing the contact method between the linkage rod 410 and the corrugated plate, the movement path of the detection rod 306 becomes more complex, which can reduce or eliminate blind spots in material movement above the vibrating screen plate 2, ensuring the comprehensiveness of the screening process.

[0035] The overall working process and principles involved in the above embodiments are as follows: When the worker pours the material into the feeding inlet 1, it first falls onto the vibrating screen plate 2. Then, the vibrating screen plate 2 is activated and vibrates up and down inside the feeding inlet 1. As the vibrating screen plate 2 moves up and down to screen the material, it can push the horizontal plate 301 to move up and down synchronously through the connecting columns 305 connected to both sides of the upper end face. One of the horizontal plates 301 will drive the rack plate 314 connected to the side wall to move up and down synchronously. The rack plate 314 and the transmission gear 311 are meshed and connected, which drives the rotating shaft 310 connected to the transmission gear 311 to rotate back and forth on the feeding inlet 1. During the rotation of the rotating shaft 310, the rotating shaft 310 can drive the dial plates 312 connected to both ends to move synchronously, and push the cylinder 313 connected to the dial plate 312 to slide back and forth inside the moving frame 302, so that the moving frame 302 moves back and forth inside the feeding inlet. The moving frame 302 moves horizontally back and forth on the side wall of the opening 1. Since the moving frame 302 is slidably connected to the lower end face of the moving plate 303 through the sliding groove 315, as the moving frame 302 moves, it can move the moving plate 303 horizontally within the through groove 304 opened on the two horizontal plates 301 through the sliding groove 315. This causes the detection rod 306 connected to the moving plate 303 to move back and forth against the surface of the vibrating screen plate 2, thus moving the material screened on the upper end face of the vibrating screen plate 2. This prevents the material from accumulating in certain areas of the vibrating screen plate 2, making the material evenly distributed on the vibrating screen plate 2. This can reduce the risk of screen hole blockage and improve screening efficiency. Furthermore, during the movement of the moving plate 303, the limiting of the horizontal plate 301 and the through groove 304 ensures that the detection rod 306 on the moving plate 303 remains in contact with the surface of the vibrating screen plate 2 during the up and down movement of the vibrating screen plate 2. During the movement of the detection rod 306 against the surface of the vibrating screen plate 2, when the screen holes on the surface of the vibrating screen plate 2 become dented, as the detection rod 306 moves to the dented and damaged screen hole, it will automatically descend on the moving plate 303, causing the limiting plate 307 connected to the upper end of the moving plate 303 to move downward synchronously, and then contact the button 308 connected to the upper end of the moving plate 303. Pressing the button 308 triggers the warning light 309 to flash, thus reminding the staff that there is an abnormality in the screen holes on the vibrating screen plate 2. This real-time monitoring function not only reduces the decrease in screening efficiency or product quality problems caused by screen hole problems, ensuring the stability and reliability of the production process, but also allows for timely detection and repair of screen hole problems, preventing further expansion and deterioration of the problem, thereby reducing the complexity and cost of maintenance work. In addition, through regular monitoring and preventive maintenance, the service life of the screen plate can be extended, reducing the overall maintenance cost. When the movable plate 303 slides within the through slots 304 formed on the two horizontal plates 301, the support blocks 411 symmetrically connected to the upper end face can drive the linkage rod 410 to move horizontally synchronously. Since the end of the linkage rod 410 away from the support block 411 is attached to the side wall of the first corrugated plate 401, it will slide along the crests of the corrugated plate 401 when the linkage rod 410 moves horizontally. Through the cooperation of the two first corrugated plates 401, the movable plate 303 can be made to sway synchronously during horizontal movement, changing the horizontal movement trajectory of the detection rod 306 connected to the movable plate 303. Not only can it be quickly adjusted and optimized according to actual needs and screening conditions, improving the adaptability and flexibility of screening operations, but by changing the horizontal movement trajectory of the detection rod 306, it can ensure that the detection rod 306 can cover more areas on the vibrating screen plate 2, even hard-to-reach corners, thereby achieving more comprehensive monitoring of the screen holes and material status. During the shaking of the moving plate 303, the moving frame 302 connected below the moving plate 303 will slide in the groove 315 opened on the lower end face of the moving plate 303, so that the moving frame 302 can adapt to the movement of the moving plate 303. When the movable plate 303 slides to the edge within the through slot 304 on the horizontal plate 301, it contacts one end of a fixed post 406 located within the through slot 304. As the movable plate 303 continues to move, it pushes the fixed post 406 into the horizontal plate 301, causing one of the lifting plates 409 to move horizontally within the horizontal plate 301. Since the lifting plate 409 on the same side is connected to the other lifting plate 409 via a connecting plate 405, one of the lifting plates 409... When 09 moves, the connecting plate 405 can drive another lifting plate 409 to move horizontally in sync, so that the two lifting plates 409 simultaneously push the sliding column 408 out from inside the horizontal plate 301, pushing the connecting frame 404 to slide upward in the vertical groove 407 opened on the support plate 402, changing the height of the first corrugated plate 401 and the second corrugated plate 403 connected between the two connecting frames 404, so that the first corrugated plate 401 and the linkage rod 410 separate, and drive the second corrugated plate 403 and the linkage rod 410 to fit together. This allows the linkage rod 410 to move along the crests of the second corrugated plate 403 sidewall when sliding in the opposite direction through the support block 411 and the moving plate 303. Because the crest intervals of the first corrugated plate 401 and the second corrugated plate 403 are different, the moving plate 303 can be simultaneously shaken when the linkage rod 410 slides along the crests of the second corrugated plate 403. However, due to the different influences of the first and second corrugated plates 401 and 403, the amplitude of the shaking of the moving plate 303 is not the same as the amplitude of the first shaking. Similarly, this increases the movement path of the detection rod 306 connected to the moving plate 303 during horizontal reciprocating movement. This not only allows for the covering and agitation of a larger area of ​​material on the vibrating screen plate 2, thus ensuring a more uniform distribution of material across the entire screen plate, reducing material accumulation in certain areas, and improving screening efficiency, but also, by changing the contact method between the linkage rod 410 and the corrugated plate, the movement path of the detection rod 306 becomes more complex, which can reduce or eliminate blind spots in the material agitation above the vibrating screen plate 2, ensuring the comprehensiveness of the screening process. When the moving plate 303 pushes the fixed column 406 on one side into the horizontal plate 301 and drives the lifting plate 409 to move horizontally, the fixed column 406 connected on the other side will follow the movement of the lifting plate 409 and slide out from the horizontal plate 301 in sync. This allows the moving plate 303 to push the fixed column 406 again when it moves to the other side in the through groove 304, thereby changing the position of the lifting plate 409 and adjusting the height of the first corrugated plate 401 and the second corrugated plate 403.
