Description

Technical Field

[0001] This application relates to the field of material detection technology, and in particular to a material detection device. Background Technology

[0002] Bulk materials require real-time monitoring of their impurity content during transportation. In related technological solutions, the material detection device includes a chute and an identification device. The identification device corresponds to a specific location on the chute, and as the material passes through the chute, the identification device can monitor the impurity content in the material in real time.

[0003] However, when using related technologies, the material tends to clump together in the chute when it is wet, and the clumped material sticks to the chute, thus affecting the detection accuracy of the identification device. Utility Model Content

[0004] In order to overcome the above-mentioned deficiencies in related technologies, the purpose of this application is to provide a material detection device, which is beneficial to improving the detection accuracy of impurity content in materials.

[0005] This application provides a material detection device, comprising:

[0006] The first chute has an inlet for connecting to a sorting device.

[0007] The second chute is located on one side of the first chute, and the inlet of the second chute is connected to the first chute.

[0008] The identification system includes a material conveyor belt and an identification device, the identification device being located above the material conveyor belt, and the discharge port of the second chute being connected to the material conveyor belt.

[0009] In one possible implementation, the inlet of the second chute passes through the side wall of the first chute and is located inside the first chute, and the inlet of the second chute has the same inlet direction as the first chute.

[0010] In one possible implementation, the width of the feed inlet of the second chute is greater than three times the sorting particle size of the sorting device.

[0011] In one possible implementation, the first chute is further provided with a flow control device, which is located above the inlet of the second chute and is used to control the flow rate of the material entering the second chute.

[0012] In one possible implementation, the flow control device includes a flap that is rotatably disposed within a first chute.

[0013] In one possible implementation, the flow control device includes a baffle plate slidably disposed within a first chute.

[0014] In one possible implementation, the second chute further includes a chute body connected to the inlet of the second chute. The chute body is inclined to the discharge direction of the first chute. A first guide plate is also provided between the chute body and the outlet of the second chute. The first guide plate is perpendicular to the discharge direction of the chute body. The outlet of the second chute is parallel to the inlet of the second chute.

[0015] In one possible implementation, the identification system further includes a frame on which the material conveyor belt and the identification device are both mounted. The frame is also provided with a second guide plate located below the discharge port of the second chute and connected to the material conveyor belt.

[0016] In one possible implementation, the second guide plate includes a guide section, an arc transition section, and a guide section, the arc transition section being located between the guide section and the guide section, the guide section being connected to the discharge port of the second chute, and the guide section being connected to the material conveyor belt.

[0017] In one possible implementation, the angle between the guide section and the conveying direction of the material conveyor belt is 45-75°.

[0018] This application provides a material detection device, including a first chute, a second chute, and an identification system. The inlet of the first chute is connected to a sorting device. The second chute is located to one side of the first chute, and its inlet is connected to the first chute. The identification system includes a material conveyor belt and an identification device, with the identification device located above the material conveyor belt. The outlet of the second chute is connected to the material conveyor belt. This application introduces a portion of the material from the first chute onto the material conveyor belt via the second chute. The identification device then detects the impurity content in the material on the material conveyor belt, thereby reflecting the impurity content in the material from the first chute. By using a uniform and stable belt-type identification technology instead of a chute-type identification device, this application solves the problems of wet coal slime caking in the chute, inconsistent material sliding speed in the chute, and the impact of posture changes during identification on detection accuracy, thus improving the detection accuracy of impurity content in the material.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0028] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] As described in the background section, when the identification device is used to directly detect the material in the chute in the related technology, if the material has a high moisture content and clumps inside the chute, the clumped material will affect the detection accuracy of the identification device.

[0030] In view of this, the present application aims to provide a material detection device that introduces part of the material in the first chute into a material conveyor belt through a second chute, and then uses an identification device to detect the impurity content in the material on the material conveyor belt, thereby reflecting the impurity content in the material in the first chute. The device uses a uniform and stable belt identification technology to replace the chute-type identification device, which solves the problems of wet coal slime caking in the chute, inconsistent sliding speed of the material in the chute, and the impact of posture changes during identification on the detection accuracy, thus improving the detection accuracy of impurity content in the material.

[0031] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the contents of this application.

[0033] Please refer to Figures 1-2 This embodiment provides a material detection device, including:

[0034] The first chute 100 has an inlet 110 for connecting to a sorting device, such as a separator. The outlet 120 of the first chute is for connecting to a receiving conveyor belt or similar equipment to transport the material to vehicles or other equipment. It is understood that the first chute 100 can be inclined vertically. Figure 1 From the perspective shown, the inlet 110 and outlet 120 of the first chute are located at the upper and lower ends of the first chute 100, respectively.

[0035] The second chute 200 is located to one side of the first chute 100. The inlet 210 of the second chute is connected to the first chute 100. The second chute 200 is used to guide some of the material inside the first chute 100 to the identification system 300. In other words, the second chute 200 is an intermediate material transfer component. The specific configuration of the second chute 200 can be determined based on requirements.

[0036] The identification system 300 includes a material conveyor belt 310 and an identification device 320. The identification device 320 is located above the material conveyor belt 310, and the discharge port 220 of the second chute is connected to the material conveyor belt 310. Exemplarily, the identification device 320 can be an existing identification device, such as an image detection device or a radiation detection device. The material conveyor belt 310 can be a belt, and the identification system 300 can also be equipped with a motor or other transmission device to drive the belt to rotate. The material in the second chute 200 falls onto the material conveyor belt 310 and passes through the identification device 320 under the drive of the material conveyor belt 310 to detect the impurity content in the material.

[0037] As described above, in this embodiment, a portion of the material in the first chute 100 is introduced onto the material conveyor belt 310 via the second chute 200. The identification device 320 then detects the impurity content in the material on the material conveyor belt 310, thereby reflecting the impurity content in the material within the first chute 100. Using a uniform and stable belt-type identification technology instead of a chute-type identification device solves the problems of wet coal slime caking in the chute, inconsistent material sliding speed in the chute, and the impact of posture changes during identification on detection accuracy, thus improving the detection accuracy of impurity content in the material.

[0038] Please continue to refer to Figure 1 In this embodiment, the inlet 210 of the second chute passes through the side wall of the first chute 100 and is located inside the first chute 100, which facilitates material receiving and allows the material in the first chute 100 to enter the second chute 200.

[0039] Preferably, the feed inlet 210 of the second chute has the same feed direction as the first chute 100. The above arrangement facilitates the entry of material in the first chute 100 into the second chute 200, thereby improving the material receiving efficiency of the second chute 200.

[0040] In this embodiment, the width of the feed inlet 210 of the second chute is greater than three times the sorting particle size of the sorting device. By limiting the width of the feed inlet 210 of the second chute to the above range, this embodiment can effectively reduce the probability of material jamming in the second chute 200.

[0041] Please continue to refer to Figure 1 In order to better control the feed rate of the second chute 200, this embodiment also provides a flow control device in the first chute 100. The flow control device is located above the feed inlet 210 of the second chute and is used to control the flow rate of the material entering the second chute 200.

[0042] In one possible implementation, the flow control device of this embodiment includes a flap 410, which is rotatably disposed within the first chute 100.

[0043] Optionally, one end of the flap 410 can be hinged to the first chute 100 via a pin or other component, while the other end of the flap 410 is a free end. When the flap 410 rotates around the hinge point, it can partially block the inlet 210 of the second chute, thereby reducing the flow rate of material entering the second chute 200. It is understood that as the rotation angle of the flap 410 changes, the aforementioned blocking range also changes, thus allowing the flow rate of material entering the second chute 200 to be adjusted as needed.

[0044] In another possible implementation, the flow control device of this embodiment includes a baffle plate 420, which is slidably disposed within the first chute 100.

[0045] Optionally, the insert plate 420 can be arranged parallel to the inlet 210 of the second chute, and the insert plate 420 can be slidably disposed within the first chute 100 via a structure such as a chute. When the insert plate 420 slides along the chute, it can partially block the inlet 210 of the second chute, thereby reducing the flow rate of material entering the second chute 200. It is understood that as the sliding distance of the insert plate 420 changes, the aforementioned blocking range also changes, thereby allowing the flow rate of material entering the second chute 200 to be adjusted as needed.

[0046] Please continue to refer to Figure 1 In this embodiment, the second chute 200 further includes a chute body 230, which is connected to the inlet 210 of the second chute. The chute body 230 is inclined to the discharge direction of the first chute 100, thereby transferring the material from the first chute 100 to the identification system 300. A first guide plate 240 is also provided between the chute body 230 and the outlet 220 of the second chute. The first guide plate 240 is perpendicular to the discharge direction of the chute body 230, and the outlet 220 of the second chute is parallel to the inlet 210 of the second chute.

[0047] In other words, this embodiment uses a first guide plate 240 to change the transmission direction of the material in the second chute 200. The first guide plate 240 can reduce the speed at which the material slides onto the material conveyor belt 310, preventing it from rolling on the material conveyor belt 310 due to excessive sliding speed, which helps to ensure the accuracy of subsequent detection.

[0048] Furthermore, the identification system 300 of this embodiment also includes a frame 330, on which the material conveyor belt 310 and the identification device 320 are all mounted. A second guide plate 340 is also provided on the frame 330. The second guide plate 340 is located below the discharge port 220 of the second chute and is connected to the material conveyor belt 310, thereby guiding the material falling from the discharge port 220 of the second chute onto the material conveyor belt 310 and ensuring that the material is spread as evenly as possible in a single layer on the material conveyor belt 310, thus ensuring the accuracy of subsequent detection.

[0049] In this embodiment, the frame 330 is also provided with a discharge port 331, which is located at the end of the material conveyor belt 310 away from the second guide plate 340. After the material on the material conveyor belt 310 is inspected, it can enter the receiving belt or other equipment through the discharge port 331 to transport the material to vehicles or other equipment, ensuring that the material used for inspection is not wasted.

[0050] Please continue to refer to Figure 2 The second guide plate 340 in this embodiment includes a guide section 341, an arc transition section 342, and a guide section 343. The arc transition section 342 is located between the guide section 341 and the guide section 343. The guide section 341 is connected to the discharge port 220 of the second chute, and the guide section 343 is connected to the material conveyor belt 310 to guide the material onto the material conveyor belt 310.

[0051] In this embodiment, the guide section 341 guides the material's conveying direction and reduces its speed. The arc transition section 342 further reduces the material's speed, facilitating a single-layer, flat distribution of material on the material conveyor belt 310 and ensuring the accuracy of subsequent inspections. The length of the guide section 343 can be set as needed, ensuring that after passing through the guide section 341 and the arc transition section 342 under gravity, the material, under inertial force, passes through the guide section 343 and enters the material conveyor belt 310. This minimizes the initial speed of the material entering the material conveyor belt 310 and prevents material accumulation on the material conveyor belt 310.

[0052] Optionally, in this embodiment, the angle between the guide section 341 and the material conveyor belt 310 (e.g., the horizontal direction) is 45-75°.

[0053] In this embodiment, the guide section 341 is set within the above-mentioned tilt angle range, which can ensure that the guide section 341 has a good guiding effect and can fully reduce the speed of the material, thereby ensuring that the subsequent material can be laid flat on the material conveyor belt 310 in a single layer, and ensuring the accuracy of subsequent detection.

[0054] In summary, this embodiment introduces a portion of the material from the first chute 100 onto the material conveyor belt 310 via the second chute 200. The identification device 320 then detects the impurity content in the material on the material conveyor belt 310, thereby reflecting the impurity content in the material within the first chute 100. The detection results are unaffected by material caking within the first chute 100, which helps improve the detection accuracy of the impurity content in the material within the first chute 100.

[0055] This embodiment uses flow control devices such as flap 410 and insert plate 420 to precisely control the flow rate of material entering the second chute 200, while effectively preventing the second chute 200 from getting blocked.

[0056] In this embodiment, the first guide plate 240 in the second chute 200 and the second guide plate 340 on the identification system 300 can effectively reduce the speed of material transfer to the material conveyor belt 310, ensuring that the material can be laid flat in a single layer on the material conveyor belt 310, thereby ensuring the accuracy of subsequent detection.
