Description

Technical Field

[0001] The utility model relates to the technical field of metal detection, in particular to a pipeline type metal detector. Background Art

[0002] The pipeline type metal detector mainly works through electromagnetic induction technology. When the material passes through the pipeline of the detector, the transmitting coil inside the detector will generate a high-frequency magnetic field, which will cover the material in the pipeline. If there are metal impurities in the material, these metal impurities will interfere with the magnetic field, generate eddy currents, and then generate a secondary magnetic field. This secondary magnetic field interacts with the original magnetic field generated by the transmitting coil, resulting in a change in the induced electromotive force in the receiving coil. This change is captured by the control system inside the detector and analyzed to determine whether there are metal impurities in the material.

[0003] Although the metal detector has shown excellent performance in accurately identifying and immediately warning of metal impurities mixed in the material, however, whenever it detects metal impurities in the material, the production line usually needs to suspend the transportation of the material so that the staff can intervene, locate and remove these impurities. If metal impurities frequently appear during the production process, then the production line will be interrupted frequently, which will undoubtedly have an adverse impact on the overall transportation efficiency of the material and the continuous operation ability of the production line.

Detailed Implementation Modes

[0015] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0016] Refer to the attached Figure 1 In Figure 1 , the a direction points to the front view and the b direction points to the right side view. The above views are only for understanding the solution.

[0017] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0018] Specifically, a pipeline metal detector includes a semi-circular pipeline 1. Legs 11 are fixedly installed at the bottom of the semi-circular pipeline 1. A metal detection mechanism for detecting metal impurities is arranged on the left side of the top of the semi-circular pipeline 1. An installation column 3 is fixedly installed at a position near the middle of the top of the semi-circular pipeline 1. The top end of the installation column 3 is fixedly installed with a top plate 31. A driving motor 32 is fixedly installed on the top of the top plate 31. The bottom end of the driving motor 32 penetrates through the bottom of the top plate 31 and extends out. A rotating screw 33 is fixedly installed at the output end of the driving motor 32 extending out of the bottom of the top plate 31. A power moving plate 34 is threadedly connected to the outside of the rotating screw 33. A bracket is fixedly installed at the bottom of the power moving plate 34 away from the center. The bottom end of the bracket is fixedly installed with an arc magnet 35. Magnet bars 36 are fixedly installed on the inner ring surface of the arc magnet 35. A circular ring slot plate 37 is fixedly installed on the outside of the installation column 3. A vertical slot plate 38 is fixedly installed on the top of the circular ring slot plate 37. The circular ring slot plate 37 communicates with the vertical slot plate 38. A limiting block 39 is movably clamped in the vertical slot plate 38. A limiting cylinder is fixedly installed at one end of the limiting block 39 close to the center of the circle. One end of the limiting cylinder close to the center of the circle is fixedly installed with the rear side of the power moving plate 34. Except for the arc magnet 35 and the magnet bars 36 in the pipeline metal detector, the rest are non-ferromagnetic metals and their alloys or non-metallic substances.

[0019] In this embodiment, when the detection device 2 detects that the materials conveyed by the semi-circular pipeline 1 contain metal impurities, the arc magnet 35 and the magnet bars 36 move downward into the materials through the cooperation of structures such as the driving motor 32, and rotate to magnetically adsorb the metal impurities in the materials. After adsorbing the metal impurities, they reset, which is convenient for quickly removing the metal impurities in the materials.

[0020] Specifically, the metal detection mechanism includes a detection device 2. The detection device 2 is fixedly installed on the left side of the top of the semi-circular pipeline 1. A fixing plate 21 is fixedly installed in the middle of the left side of the detection device 2. A triangular shunt block 22 is fixedly installed at the bottom left of the fixing plate 21.

[0021] In this embodiment, the triangular shunt block 22 is used to initially disperse the materials and reduce blockage, which is convenient for the detection device 2 to detect metal impurities.

[0022] Specifically, an expansion slot is opened at a position close to the bottom on the rear inner wall of the vertical slot plate 38. The expansion slot communicates with the circular ring slot plate 37. A guiding plate is rotatably connected to the left side of the rear inner wall of the expansion slot.

[0023] In this embodiment, when the limiting block 39 rotates counterclockwise, it can enter the vertical slot plate 38 from the circular ring slot plate 37 with the cooperation of the guiding plate.

[0024] Specifically, a circular baffle is fixedly installed at the bottom end of the drive motor 32, and an auxiliary circular hole is formed on the inner ring surface of the arc magnet 35.

[0025] In this embodiment, the downward-moving power moving plate 34 is blocked by the circular baffle, and the arc magnet 35 can rise higher through the auxiliary circular hole.

[0026] Specifically, the outer diameter of the arc magnet 35 is smaller than the inner wall diameter of the semi-circular pipe 1.

[0027] In this embodiment, the arc magnet 35 can enter the semi-circular pipe 1 when moving downward.

[0028] During use, since the left leg 11 is higher than the right leg 11, the material inside the semi-circular pipe 1 flows from left to right. When the material flows, the triangular flow splitter 22 separates the material for flow, facilitating the detection device 2 to detect the material. When the material flows to the bottom of the detection device 2, the detection device 2 detects the flowing material. If the detected material contains metal impurities, the drive motor 32 is started. The drive motor 32 drives the rotating screw 33 to rotate clockwise. When the rotating screw 33 rotates, it drives the power moving plate 34 to move downward under the restriction of the limiting block 39. The power moving plate 34 drives the arc magnet 35 to move downward through the bracket. The arc magnet 35 drives the magnet bar 36 to move downward. When the limiting block 39 moves downward from the vertical slot plate 38 to enter the circular ring slot plate 37, the arc magnet 35 moves downward to a position close to the inner wall of the semi-circular pipe 1, and the power moving plate 34 moves downward until it contacts the circular block. At this time, the limiting block 39 releases the restriction on the power moving plate 34, and the rotating screw 33 drives the non-downward-movable power moving plate 34 to rotate. The power moving plate 34 drives the limiting block 39 to rotate along the circular ring slot plate 37 through the limiting cylinder. The power moving plate 34 drives the arc magnet 35 to rotate through the bracket, and the arc magnet 35 drives the magnet bar 36 to rotate. The metal impurities in the material are magnetically adsorbed by the rotating arc magnet 35 and magnet bar 36. After the arc magnet 35 and magnet bar 36 adsorb the metal impurities, the drive motor 32 drives the rotating screw 33 to rotate counterclockwise. At this time, when the limiting block 39 rotates counterclockwise, it enters the vertical slot plate 38 from the circular ring slot plate 37 under the restriction of the guiding plate, so that the limiting block 39 restricts the power moving plate 34 again. The power moving plate 34 drives the arc magnet 35 and magnet bar 36 to move upward away from the material through the bracket. At this time, the employee can remove the metal impurities adsorbed on the arc magnet 35 or magnet bar 36. When the metal impurities in the material are detected and quickly processed, the removal efficiency of the metal impurities is improved, and at the same time, the purity of the material and the stability of the production line are enhanced, which is beneficial to improving the overall conveying efficiency and continuous operation ability.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
