However, in practical applications, this type of magnetic separator cannot accurately collect qualified aggregates, resulting in low screening efficiency, especially in large-scale collection operations. It cannot guarantee that the sorted materials will fully meet the standards, and there may be mixing of unqualified materials. Summary of the Invention
[0003] In view of the problem mentioned in the background art that the existing technology cannot guarantee the accuracy of screening, this utility model provides a residual magnetic detection device for building aggregates, which detects different areas of the aggregates and determines the qualification of the area, thereby ensuring the cleanliness of the aggregates collected later and reducing the mixing of unqualified materials.
[0004] To achieve the above objectives, the present invention adopts the following technical solution.
[0005] A residual magnetic field testing device for building aggregates includes a testing and conveying unit with a testing component. A material distributor is connected to the end of the testing and conveying unit, and several discharge conveying units are connected to the material distributor. Each discharge conveying unit includes a qualified conveying unit and a non-qualified conveying unit. Each discharge conveying unit is connected to a corresponding receiving bin. The material distributor includes an actuation unit capable of switching between the testing and conveying units and between the discharge conveying units. The material distributor is connected to the testing component, and the testing component controls the actuation unit.In this application, materials are conveyed via a detection conveying unit, which includes, but is not limited to, conveyor belts and drive rollers, preferably with low magnetic properties to improve the detection accuracy of the detection components. After the aggregate is conveyed to the detection unit via the detection conveying unit, the residual magnetism of the aggregate is detected by the detection unit. Subsequently, the aggregate continues to be conveyed by the detection conveying unit to the sorting machine. The sorting machine classifies aggregates of different qualities according to the detection feedback from the detection unit and places them into different discharge conveying units. The sorting machine includes, but is not limited to, three-way or two-way sorters or movable hoppers. If the sorting machine is a multi-way sorter, a deflector is set inside to change the outlet position of the aggregate, thereby realizing the sorting of aggregates. The material is transferred to different discharge conveying units. If a movable hopper is used, the hopper is moved above the corresponding discharge conveying unit by controlling its movement, thus conveying the material to the designated discharge conveying unit. Other structures capable of sorting and transferring materials can also be used (many structures capable of this function exist in the prior art and will not be described in detail). These structures all include actuation units. The actuation unit's action changes the core component of aggregate conveying, and the actuation command of the actuation unit relies on the detection results of the detection unit. For example, when the detection result of the detection unit does not meet the standard, the actuation unit in the material sorter is delayed according to the conveying speed of the detection conveying unit. When the aggregate being tested moves to the end of the testing and conveying unit, the actuating unit moves the aggregate to the non-conforming conveying unit. If the test result meets the standard, the actuating unit moves the corresponding aggregate to the conforming conveying unit, thus achieving accurate classification. Several conforming conveying units are provided to correspond to the screening of different types of aggregate. Since this application uses a testing component to perform conformity testing on the aggregate on the testing and conveying unit, any non-conforming aggregate in the testing area will be sorted away by the sorting machine. This ensures that only conforming aggregate is transported into the conforming conveying unit, guaranteeing the cleanliness of the collected conforming aggregate and preventing aggregate mixing during the testing process. During the transfer process of the material sorting machine, the aggregates are moved to prevent unqualified aggregates from mixing with qualified aggregates, thus ensuring the accuracy of material sorting. The detection components include, but are not limited to, magnetically shielded detection cylinders, which can improve the detection accuracy and reduce external magnetic interference. Other residual magnetic detection components can also be used (there are many structures in the existing technology that can achieve this function, which will not be described in detail). The detection components are connected to the action unit, and the detection signals of the detection components can be processed and fed back to the action unit, which will act at the corresponding time to process the aggregates detected by the detection components at the corresponding detection signal. In practical applications, the connection methods between the detection components and the action unit include, but are not limited to, PLC and microcontroller.
[0006] Preferably, the detection component includes a detection perforation through which the detection conveying unit passes. By providing the detection perforation on the detection component, the perforation can penetrate and accommodate the detection conveying unit, ensuring comprehensive and accurate detection of the unit and improving detection precision.
[0007] Preferably, the detection assembly includes a detection body, a support frame connected to the detection body, and movable rollers connected to the bottom of the support frame. By setting up the support frame and installing movable rollers on the support frame, the detection body can be moved relative to the detection conveyor unit by pushing the support frame, thereby changing the relative position of the detection body and improving the adaptability of the entire production line device.
[0008] Preferably, the detection component includes a cylinder body and a cylinder cover, with the cylinder cover detachably connected to the cylinder body. A guide rail unit is also provided between the cylinder body and the cylinder cover. The detection component consists of a cylinder body and a cylinder cover. A probe is installed inside the cylinder body for detection, while the cylinder cover ensures a sealing and shielding effect. A detection perforation is located on the top of the cylinder cover. The cylinder cover and the cylinder body are detachably connected. The two are connected by a guide rail unit. Specifically, a slide rail can be provided on the cylinder body, and a slider that can slide to connect to the slide rail is provided on the cylinder cover. During use, the cylinder cover can be separated from the cylinder body by pushing or pulling.
[0009] Preferably, the material distributor is a multi-channel material distributor, which includes several outlets connecting to various discharge conveying units. The actuating unit is a movable paddle located inside the multi-channel material distributor. The material distributor is configured as a multi-channel material distributor, which includes, but is not limited to, three or four outlets. In practical applications, it can be configured according to requirements, with at least two outlets, ensuring one for each unqualified conveying unit and one for each qualified conveying unit. The multi-channel material distributor has one inlet connected to the detection conveying unit and multiple outlets connected to the discharge conveying units. The movement of the internal movable paddle changes the outlet connected to the inlet, allowing aggregate to be discharged from different outlets and enter the corresponding discharge conveying unit. The movable paddle is controlled by a detection signal from the detection unit.
[0010] Preferably, the sorting machine is a sorting hopper, and the actuation unit is a drive component capable of moving the sorting hopper. The sorting hopper includes a docking port, which switches between various discharge conveying units when the sorting hopper moves. Alternatively, the sorting machine can also be a sorting hopper, wherein the sorting hopper can be moved by a drive component to align its docking port with different discharge conveying units. The drive component is the actuation unit, which aligns the sorting hopper with discharge conveying units at different positions based on detection signals from the detection component.
[0011] The qualified conveying unit includes a multi-size particle conveyor belt. A size screening machine is connected to the end of the multi-size particle conveyor belt furthest from the distributor. The size screening machine includes several screening openings, each of which connects to a corresponding receiving bin. In practical applications, since the size of the stones varies, it is necessary to screen and classify the stones. The screening machine sorts stones of different sizes into different receiving bins, thereby facilitating subsequent collection and use and improving sorting accuracy.
[0012] Preferably, the settling trough is located at the end of the detection and conveying unit, and the material distributor is located inside the settling trough. The settling trough at the end of the detection and conveying unit provides ample installation space for the material distributor, thus ensuring sufficient operating space for the actuating unit and facilitating the subsequent installation of the discharge conveying unit.
[0013] Preferably, a vibrating feeder is installed at the end of the inspection and conveying unit furthest from the distributor. The vibrating feeder at this end can vibrate and flatten the aggregate before conveying it to the inspection and conveying unit, thus preventing aggregate from piling up on the unit. The vibrating feeder can initially ensure the flatness and uniformity of the aggregate.
[0014] Preferably, the vibrating feeder includes a feeding opening with an independent lifting baffle. The feeding opening allows material to be conveyed from the vibrating feeder to the detection and conveying unit. The independent lifting baffle controls the amount of material output from the feeding opening by raising and lowering it, thus achieving material control. The independent lifting baffle can be directly installed on the buffer hopper or connected above the feeding opening via a bracket; the key is to ensure that the independent lifting baffle can move up and down relative to the feeding opening to control the feeding amount.
[0015] Preferably, the vibrating feeder is connected to a buffer hopper. The vibrating feeder includes a feeding pan, and the bottom of the buffer hopper has a connecting opening that communicates with the feeding pan. The buffer hopper on the vibrating feeder can store aggregates, and the connecting opening at the bottom of the buffer hopper enables communication with the feeding pan, thereby allowing the vibrating feeder to continuously supply aggregates to the detection and conveying unit.
[0016] Preferably, the detection and conveying unit has an aggregate leveling component on the side of the detection component away from the distributor. The aggregate leveling component, positioned on the side of the detection component away from the distributor, allows the aggregate to be leveled before entering the detection component, ensuring a smooth and uniform surface, thus improving detection accuracy in the detection unit. Furthermore, the leveling thickness can be controlled by adjusting the gap between the aggregate leveling component and the detection and conveying unit. Specific solutions include, but are not limited to: installing slide rail supports on both sides of the detection and conveying unit, and controlling the relative position of the leveling component on the detection and conveying unit by sliding the aggregate leveling component on the slide rail supports. Further, the aggregate leveling component includes a mounting plate and a scraper; alternatively, a slide rail and a slider can be connected between the mounting plate and the scraper, allowing the scraper to slide relative to the mounting plate, thereby controlling the scraper's position.
[0017] The beneficial effects of this utility model are as follows:
[0018] (1) It can simplify the magnetic separation collection process, detect different areas of the aggregate, and make a qualified judgment on the area, so as to ensure the cleanliness of the aggregate collected later and reduce the mixing of unqualified materials.
[0019] (2) It can separate different types of aggregates without changing the overall layout; the switching can be completed simply by changing the action state of the action unit.
[0020] (3) It can further distinguish and screen stone materials, ensuring the accuracy of screening and facilitating subsequent recycling.

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0039] Example 1:
[0040] like Figure 1 As shown, a residual magnetism detection device for building aggregates includes a detection conveying unit 1, a detection component 2 on the detection conveying unit 1, a material distributor 3 connected to the end of the detection conveying unit 1, and a plurality of discharge conveying units 4 connected to the material distributor 3. The discharge conveying units 4 include qualified conveying units 41 and unqualified conveying units 42. Each discharge conveying unit 4 is connected to a corresponding receiving bin 43. The material distributor 3 includes an action unit that can switch the detection conveying unit 1 to each discharge conveying unit 4. The material distributor 3 is connected to the detection component 2, and the detection component 2 controls the action unit to operate.
[0041] In this embodiment, material is conveyed through a detection conveying unit 1, which is a conveyor belt. A low-magnetic conveyor belt is selected in this embodiment to improve the detection accuracy of the detection component 2. After the aggregate is conveyed to the detection unit by the detection conveying unit 1, the residual magnetism of the aggregate is detected by the detection unit. The aggregate is then continued to be conveyed by the detection conveying unit 1 to the sorting machine 3. The sorting machine 3 classifies aggregates of different qualities according to the detection feedback from the detection unit and distributes them to different discharge conveying units 4. A paddle is installed inside the sorting machine 3 to change the outlet position of the aggregate, thereby transferring the aggregate to different discharge conveying units 4 within the sorting machine 3. The action unit is the core component that changes the aggregate conveying process, and its action command relies on the detection result of the detection unit. For example, if the detection result of the detection unit does not meet the standard, the action unit inside the sorting machine 3 is delayed according to the conveying speed of the detection conveying unit 1. When the detected aggregate moves to the end of the detection conveying unit 1, the action unit actuates to convey this portion of the aggregate. The aggregate is sent to the non-conforming conveying unit 42. If the test result meets the standard, the control unit will move the corresponding aggregate to the conforming conveying unit 41, thereby achieving accurate classification. The conforming conveying unit 41 is used to screen different types of aggregate. Since the detection component 2 is used in this application to perform conformity testing on the aggregate in the detection conveying unit 1, non-conforming aggregate in the detection area will definitely be sorted away by the sorting machine 3. This ensures that conforming aggregate is transported into the conforming conveying unit 41, guaranteeing the cleanliness of the conforming aggregate collection. The aggregate will not be mixed during the testing process. The aggregate will only be moved during the transfer process of the sorting machine 3, thus avoiding the situation where non-conforming aggregate is mixed with conforming aggregate and ensuring the accuracy of sorting. The detection component 2 is connected to the action unit. The detection signal of the detection component 2 can be processed and fed back to the action unit, which will act at the corresponding time to process the aggregate detected by the detection component 2 corresponding to the detection signal. In this embodiment, the connection between the detection component and the action unit is a PLC.
[0042] like Figure 2 , 7 As shown, the detection component 2 includes a detection perforation 21, through which the detection conveying unit 1 passes. The detection component 2 includes a detection body 22, on which a support frame 23 is connected, and at the bottom of the support frame 23 are movable rollers 24. The feeder 3 is a multi-channel feeder 31, which includes several discharge ports 32 connecting to various discharge conveying units 4. The actuation unit is a movable lever located inside the multi-channel feeder 31. The detection component includes a cylinder body 25 and a cylinder cover 26, which is detachably connected to the cylinder body 25. A guide rail unit 27 is also provided between the cylinder body 25 and the cylinder cover 26.
[0043] A detection perforation 21 is provided on the detection component 2, allowing the detection perforation 21 to penetrate and accommodate the detection conveying unit 1, ensuring accurate detection of the detection conveying unit 1 from all directions and improving detection precision. A support frame 23 is provided, and movable rollers 24 are provided on the support frame 23, allowing the detection body 22 to move relative to the detection conveying unit 1 by pushing the support frame 23, thus changing the relative position of the detection body 22 and improving the adaptability of the entire production line device. The material distributor 3 is set as a multi-pass distributor 31. In practical applications, it can be set according to requirements, with at least two, ensuring one corresponding to a non-conforming conveying unit 42 and one to a conforming conveying unit 41. In this embodiment, three discharge conveying units 4 are provided, therefore the multi-pass distributor 31 in this embodiment is a four-pass distributor. The movement of the internal movable lever changes the discharge port 32 connected to the inlet 33, allowing the aggregate to be discharged from different discharge ports 32 and enter the corresponding discharge conveying unit 4. The control of the movable lever is achieved through the detection signal of the detection unit. Control is performed; in this embodiment, the detection component consists of a cylinder body 25 and a cylinder cover 26. A probe is installed inside the cylinder body 25 for detection, while the cylinder cover 26 ensures a sealing and shielding effect. The detection perforation is set on the top of the cylinder cover 26. The cylinder cover 26 and the cylinder body 25 are detachably connected. The two are connected by a guide rail unit 27. Specifically, a slide rail 271 can be provided on the cylinder body 25, and a slider 272 that can slide and connect to the slide rail 271 can be provided on the cylinder cover 26. During use, the cylinder cover 26 can be separated from the cylinder body 25 by pushing and pulling the cylinder cover 26.
[0044] like Figure 3 As shown, the qualified conveying unit 41 includes a sand conveyor belt 411 and a stone conveyor belt 412. The stone conveyor belt 412 is connected to a size screening machine 413 at the end away from the material distributor 3. The size screening machine 413 includes a number of screening openings 4131, and each screening opening 4131 is connected to a corresponding receiving bin 43.
[0045] The qualified conveying unit includes a multi-size particle conveyor belt 410. A size screening machine is connected to the end of the multi-size particle conveyor belt 410 away from the distributor. The size screening machine includes several screening openings, each connected to a corresponding receiving bin. In practical applications, since the size of the stones varies, it is necessary to screen and classify them. The size screening machine 413 classifies stones of different sizes into different receiving bins 43, thereby facilitating subsequent collection and use and improving sorting accuracy. In this embodiment, the qualified conveying unit 41 is divided into a sand conveyor belt 411 and a gravel conveyor belt 412. The sand and gravel conveyor belt 412 is a multi-size particle conveyor belt 410. When sorting sand, the action unit is set to switch only between the sand conveyor belt 411 and the unqualified conveying unit 42. When sorting gravel, the action unit is controlled to switch between the gravel conveyor belt 412 and the unqualified conveying unit 42. This realizes the sorting operation of different types of aggregates without changing the receiving bin 43, ensuring that the entire device remains unchanged, only the action state of the corresponding action unit needs to be changed. Since the gravel has different size specifications, the gravel is further screened. The screening machine classifies the gravel of different sizes into different receiving bins 43, which facilitates subsequent collection and use and improves the sorting accuracy.
[0046] like Figure 1 , 6 As shown, the settling tank 5 is located at the end of the detection and conveying unit 1, and the material distributor 3 is located inside the settling tank 5. The settling tank 5 is located at the end of the detection and conveying unit 1, which provides sufficient installation space for the material distributor 3, thus allowing the actuating unit to have sufficient operating space and facilitating the subsequent installation of the discharge conveying unit 4.
[0047] like Figure 4 As shown, a vibrating feeder 6 is installed at the end of the detection conveying unit 1 away from the material distributor 3. A buffer hopper 7 is connected to the vibrating feeder 6. The vibrating feeder 6 includes a feeding plate 61. The bottom of the buffer hopper 7 is provided with a connecting opening 71 that connects to the feeding plate 61. The vibrating feeder includes a feeding opening 62, and an independent lifting baffle 9 is provided on the feeding opening 62.
[0048] A vibrating feeder 6, located at the end of the inspection and conveying unit 1 furthest from the distributor 3, vibrates and flattens the aggregate before conveying it to the inspection and conveying unit 1, thus preventing aggregate from piling up on the inspection and conveying unit 1. The vibrating feeder 6 initially ensures the flatness and uniformity of the aggregate. A buffer hopper 7, located on the vibrating feeder 6, stores the aggregate, and a connecting opening 71 at the bottom of the buffer hopper connects it to the feed pan 61, allowing the vibrating feeder 6 to continuously supply aggregate to the inspection and conveying unit 1. The material in the vibrating feeder can be conveyed to the detection and conveying unit through the feeding opening 62. An independent lifting baffle 9 is set on the feeding opening 62. By raising and lowering the independent lifting baffle 9, the amount of material output from the feeding opening 62 can be controlled, thereby realizing the control of the material. In this embodiment, the independent lifting baffle 9 is directly installed on the buffer hopper. Specifically, the independent lifting baffle 9 includes a fixed fixing plate and a lifting plate that can be raised and lowered. The lifting plate is provided with multiple slots. By moving the lifting plate, different slots are connected to the fixed plate, thereby ensuring the lifting and fixing effect of the lifting plate.
[0049] like Figure 5 As shown, the detection and conveying unit 1 has an aggregate leveling component 8 on the side of the detection component 2 away from the distributor 3. The aggregate leveling component 8 is positioned on the detection and conveying unit 1 on the side of the detection component 2 away from the distributor 3, ensuring that the aggregate is leveled by the aggregate leveling component 8 before entering the detection component 2 for detection, guaranteeing the uniformity of the aggregate distribution. Furthermore, the leveling thickness can be controlled by adjusting the gap between the aggregate leveling component 8 and the detection and conveying unit 1.
[0050] The assembly and operation process of the residual magnetic field detection device for building aggregates in this embodiment is as follows: In this embodiment, the detection conveying unit 1 is an elevated conveyor belt, and a detection component 2 is set in the middle of the detection conveying unit 1. In this embodiment, the detection component 2 is a multi-layer magnetic shielding system array-type three-axis fluxgate. A detection through hole 21 is opened on the detection body 22 of the detection component 2, which can accommodate the detection conveying unit 1 to pass through. A support frame 23 is set below the detection body 22, and a movable roller 24 is set at the bottom of the support frame 23. The movable roller 24 can drive the detection component 2 to move in phase. The displacement of the detection conveying unit 1 is monitored. At one end of the detection conveying unit 1, a combination of a vibrating feeder 6 and a buffer hopper 7 is provided. At the other end of the detection conveying unit 1, a distributor 3 and various discharge conveying units 4 connected to the distributor 3 are provided. An aggregate leveling component 8 is provided on the side of the detection conveying unit 1 closest to the vibrating feeder 6. The aggregate leveling component 8 can level the aggregate. Specifically, in this embodiment, vertically arranged slide rail supports 81 are provided on both sides of the detection conveying unit 1. The slide rail supports 81 are connected to the mounting plate 83 via sliders 272 and corner fittings, allowing the mounting plate to move smoothly. The mounting plate 83 can move up and down relative to the slide rail bracket 81. Bolts are provided on the corner fittings, which can be tightened and fixed as needed to ensure reliable connection. Furthermore, a mounting slide rail 831 is provided below the mounting plate 83. The mounting slide rail 831 is also connected to the scraper 82 through a slider 272, corner fittings, and bolts, allowing the scraper 82 to be further adjusted relative to the mounting plate 83, ensuring the flexibility of adjustment. In this embodiment, the scraper 82 has a triangular cone structure, with the protrusion facing the vibrating feeder 6. In this embodiment, the qualified conveying unit 41 includes two units. These are a sand conveyor belt 411 and a gravel conveyor belt 412, and four corresponding receiving bins 43 are provided. One of them is used to collect unqualified aggregates, and the other three are used to collect qualified aggregates. The receiving bins 43 for collecting qualified aggregates include one receiving bin 43 for collecting sand and two receiving bins 43 for collecting gravel of different sizes. At the end of the gravel conveyor belt 412, a size screening machine 413 is provided. The size screening machine 413 has two screening openings 4131, which correspond to the two gravel receiving bins 43 respectively, and can collect large gravel and small gravel respectively.
[0051] In this embodiment, during operation, aggregate is fed to the vibrating feeder 6 through the buffer hopper 7. The vibration of the vibrating feeder 6 causes the aggregate to spread out and be transferred to the detection conveying unit 1. The detection conveying unit 1 then conveys the aggregate to the detection component 2. The detection component 2 detects the qualification of the aggregate entering the unit. As needed, additional detection probes can be added to perform separate scanning of multiple areas of the aggregate, thereby improving detection accuracy. After the detection is completed, the detection unit collects the detection data and feeds it back to the action unit in the sorting machine 3. The action unit delays its movement. When the aggregate corresponding to the signal moves to the end of the detection conveying unit 1, it performs an action to guide the aggregate to the corresponding discharge conveying unit 4. The aggregate then enters the corresponding receiving hopper 43 through the discharge conveying unit 4, completing the classification and collection. This embodiment simplifies the magnetic separation collection process through the aforementioned structure, allowing for the detection of different areas of the aggregate to determine their suitability and ensuring the cleanliness of subsequently collected aggregate, thus reducing the mixing of substandard materials. It enables the separation of different types of aggregate without altering the overall layout; switching is achieved simply by changing the operating state of the actuating unit. It further differentiates and screens stone materials, ensuring screening accuracy and facilitating subsequent recycling. The vibrating feeder and aggregate leveling component ensure uniform aggregate feeding, improving the detection accuracy of subsequent testing components.

[0053] Unlike Embodiment 1, in this embodiment, the sorting machine 3 is a sorting hopper, and the actuation unit is a drive component capable of moving the sorting hopper. The sorting hopper includes a docking port, which switches between various discharge conveying units 4 when the sorting hopper moves. The sorting machine 3 can also be a sorting hopper, wherein the sorting hopper can be moved by the drive component, thereby aligning the docking port of the sorting hopper with different discharge conveying units 4. The drive component is the actuation unit, which drives the sorting hopper to align with the discharge conveying units 4 at different positions according to the detection signal of the detection component 2.
