Description

Technical Field

[0001] This utility model relates to the field of radiation detection technology, and in particular to an automatic radiation detection device for scrap steel. Background Technology

[0002] Scrap steel is usually recycled and reprocessed for reuse to save resources. Before processing, the scrap steel needs to be tested for radiation to ensure its safety.

[0003] In the prior art, such as the automatic radiation detection device for scrap steel disclosed in Chinese Patent No. CN217879432U, which relates to the field of scrap steel radiation detection technology, this utility model includes a bracket and a mounting plug. The bracket has a mounting hole at its upper part, and the diameter of the upper part of the mounting plug is larger than the diameter of the mounting hole. Two limiting pins are elastically slidably fitted inside the mounting plug, and a compression ring corresponding to the multiple limiting pins is slidably fitted on the mounting plug. A mounting plate is hinged to the bottom end of the mounting plug. This patent allows the lower part of the limiting pins to slide completely into the mounting plug by pulling the compression ring upwards. Then, the detector and the lower part of the mounting plug pass through the mounting hole on the bracket, with the upper part of the mounting plug blocked on the bracket. The upper part of the mounting plug supports the detector. Then, the compression ring is released, and the lower part of the limiting pin slides out, limiting the mounting plug to the bracket. This facilitates quick installation of the detector on the upper side of the bracket, thus improving the efficiency of detector installation, as well as disassembly, maintenance, and replacement.

[0004] However, this patent still has shortcomings. When the patent is used for detection, it mainly scans the scrap steel from top to bottom using a detector. However, when the scrap steel is stacked, the scrap steel at the bottom and on the sides cannot be fully scanned, which leads to inaccurate scanning results. Therefore, an automatic scrap steel radiation detection device is proposed to solve the above problems. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes an automatic radiation detection device for scrap steel. It utilizes a driving component to rotate a drive rack, causing the radiation detector located within the inner ring of the drive rack to rotate along the inner ring of the drive rack. This achieves comprehensive detection of the scrap steel in the detection basket, resulting in more complete and accurate detection.

[0006] The technical solution to achieve the purpose of this utility model is: an automatic radiation detection device for scrap steel, including a detection platform, on which a detection basket and a feeding component are respectively arranged, the feeding component being connected to the detection basket, and further comprising;

[0007] A detection ring, wherein a driving gear ring is slidably connected to the inner wall of the detection ring, and a radiation detector is provided on the inner ring surface of the driving gear ring;

[0008] A drive frame is provided on the outside of the detection platform. A drive compartment is fixedly connected to the top of the drive frame. A drive component is provided inside the drive compartment and is connected to a drive gear ring.

[0009] In some embodiments, the feeding assembly includes a limiting rod fixedly connected to the inner wall of the detection platform, a feeding screw rotatably connected to the inner wall of the detection platform, a feeding motor fixedly connected to one side of the detection platform, and the output end of the feeding motor being coaxially fixed with the feeding screw.

[0010] In some embodiments, the feeding assembly further includes two connecting blocks that are slidably connected to the inner wall of the detection platform, one of the connecting blocks being screwed to the feeding screw, and the other connecting block being slidably connected to the limiting rod, wherein the lower surface of the detection basket is fixedly connected to the upper surfaces of the two connecting blocks.

[0011] In some embodiments, the driving component includes a drive screw rotatably connected to the inner wall of the driving chamber, a drive motor is fixedly connected to one side of the driving chamber, and the output end of the drive motor is coaxially fixed with the drive screw.

[0012] In some embodiments, a drive block is slidably connected to the inner wall of the drive chamber, the drive block is screwed to a drive screw, and a drive rack is fixedly connected to the lower surface of the drive screw, the drive rack meshing with a drive gear ring.

[0013] Compared with existing technologies, the significant advantages of this invention are:

[0014] This invention, through the setting of a detection ring and a driving component, allows scrap steel to be placed in a detection basket during detection. The feeding motor and drive motor are then started. The feeding motor drives the feeding screw to rotate, enabling the connecting block to move the detection basket into the area of ​​the detection ring and radiation detector. The radiation detector first detects from top to bottom. Then, as the drive motor drives the drive screw to rotate, the drive block moves the drive rack under the action of the thread. The movement of the drive rack causes the entire drive ring to rotate. The radiation detector, located on the inner ring of the drive rack, rotates along the inner ring of the drive rack, thus achieving a comprehensive detection of the scrap steel in the detection basket. This results in a more thorough and accurate detection.

[0015] This solves the problem that existing detection devices are prone to inaccurate detection of waste materials at the bottom due to raw material accumulation. Attached Figure Description

[0024] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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 skilled in the art without creative effort are within the protection scope of the present invention.

[0025] like Figure 1 As shown, an automatic radiation detection device for scrap steel includes a detection platform 1, on which a detection basket 2 and a feeding component 3 are respectively arranged. The feeding component 3 is connected to the detection basket 2. In order to reduce the influence of other metals on the detection, the detection basket 2 in this application is made of plastic material, or it can be made of carbon fiber material.

[0026] The detection ring 4 has a drive gear ring 5 slidably connected to its inner wall. Both sides of the drive gear ring 5 are provided with protruding circular sliding rings. The inside of the detection ring 4 is provided with a circular sliding groove for the drive gear ring 5 to slide. The two are adapted to each other to allow the drive gear ring 5 to rotate. A radiation detector 6 is provided on the inner ring surface of the drive gear ring 5. One side of the inner ring surface of the drive gear ring 5 is not surrounded by the detection ring 4. A mounting base for mounting the radiation detector 6 is welded and fixed on the inner ring surface of the drive gear ring 5. The radiation detector 6 is a portable type with a built-in high-sensitivity GM counter tube as the detector.

[0027] A drive frame 7 is provided on the outside of the detection platform 1. A drive chamber 8 is fixedly connected to the top of the drive frame 7. A drive component 9 is provided inside the drive chamber 8. The drive component 9 is connected to the drive gear ring 5. The drive component 9 can make the drive gear ring 5 rotate, thereby realizing the all-round detection of the radiation detector 6.

[0028] like Figure 2 As shown, in one embodiment, the detection platform 1 has two receiving slots for accommodating the detection components. The feeding component 3 includes a limiting rod 301 fixedly connected to the inner wall of the detection platform 1. A feeding screw 302 is rotatably connected to the inner wall of the detection platform 1. A feeding motor 303 is fixedly connected to one side of the detection platform 1. The output end of the feeding motor 303 extends into the receiving slot. The output end of the feeding motor 303 is coaxially fixed with the feeding screw 302. The feeding motor 303 is selected as a servo motor that can be electrically controlled to rotate, which facilitates loading and unloading.

[0029] In one embodiment, the feeding assembly 3 further includes two connecting blocks 304 that are slidably connected to the inner wall of the detection platform 1. One connecting block 304 has a threaded hole that is adapted to the feeding screw 302, and the other connecting block 304 is screwed to the feeding screw 302. The other connecting block 304 has a sliding hole that is adapted to the limiting rod 301, and the other connecting block 304 is slidably connected to the limiting rod 301. The lower surface of the detection basket 2 is fixedly connected to the upper surfaces of the two connecting blocks 304, and the lower surface of the detection basket 2 is slidably connected to the upper surface of the detection platform 1.

[0030] like Figure 3 , Figure 4 as well as Figure 5 As shown, in one embodiment, the driving component 9 includes a driving screw 901 rotatably connected to the inner wall of the driving chamber 8, a driving motor 902 fixedly connected to one side of the driving chamber 8, the output end of the driving motor 902 penetrating into the driving chamber 8, and the output end of the driving motor 902 being coaxially fixed with the driving screw 901.

[0031] In one embodiment, a drive block 903 is slidably connected to the inner wall of the drive chamber 8. A threaded hole adapted to the drive screw 901 is opened through the drive block 903. The drive block 903 is screwed to the drive screw 901. A drive rack 904 is fixedly connected to the lower surface of the drive screw 901. The drive rack 904 meshes with the drive gear ring 5. The drive frame 7 has gaps on both sides that allow the drive rack 904 to pass through, ensuring that the drive rack 904 has a sufficient range of movement.

[0032] The specific working method is as follows: When the automatic scrap steel radiation detection device is used, the scrap steel raw material is first placed in the detection basket 2. The feeding motor 303 and the drive motor 902 are started. The feeding motor 303 drives the feeding screw 302 to rotate, so that the connecting block 304 can drive the detection basket 2 into the area of ​​the detection ring 4 and the radiation detector 6. At this time, the radiation detector 6 first detects from top to bottom. Then, as the drive motor 902 drives the drive screw 901 to rotate, the drive block 903 drives the drive rack 904 to move under the action of the thread. The movement of the drive rack 904 will cause the drive gear ring 5 to rotate. The radiation detector 6, located in the inner ring of the drive rack 904, will rotate with the inner ring of the drive rack 904 as the motion trajectory, thereby achieving the effect of all-round detection of the scrap steel in the detection basket 2. The detection is more comprehensive and the detection results are more accurate. After the detection is completed, the current scrap is taken out and the next batch of scrap is put in. The above operation is repeated for batch detection.
