Description

Technical Field

[0001] The present invention relates to the field of electrical grade magnesium oxide, in particular to a device for detecting the impurity content of electrical grade magnesium oxide. Background Art

[0002] Electrical-grade magnesium oxide is an important material used in the electrical industry, mainly used in cable insulation, power equipment, and electrical insulation. It is extracted from magnesium ore through high-temperature sintering and has good electrical insulation properties, high temperature resistance and chemical stability. Electrical-grade magnesium oxide is usually required to have a high purity to ensure its good performance in electrical equipment. However, like any industrial product, electrical-grade magnesium oxide may contain some impurities, mainly from raw materials (such as magnesium ore) or possible contamination during the production process.

[0003] Common impurities in existing electrical-grade magnesium oxide are mostly metal impurities, usually including iron, silicon, aluminum and calcium. In order to improve the performance of the material, the content of these impurities is minimized during the production process. X-ray fluorescence spectroscopy is usually used to detect the content of internal impurities. In order to ensure the accuracy of the overall detection, the sample needs to be pre-treated, and the electrical-grade magnesium oxide is ground into powder and then evenly laid on the test tray. During the laying process, the staff needs to use special tools for laying, which wastes too much manpower and material resources. After the test is completed, in order to facilitate the subsequent sample testing, the staff is required to manually clean the powdered electrical-grade magnesium oxide on the test tray, which greatly reduces the overall detection efficiency.

[0004] In summary, when using X-ray fluorescence spectrometry to detect the content of internal impurities, staff are required to manually operate and lay it out, which wastes too much manpower and material resources. In addition, staff are required to manually clean the powdered electrical-grade magnesium oxide on the test plate afterwards, which greatly reduces the overall detection efficiency. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an impurity content detection device for electrical-grade magnesium oxide to solve the technical problems of excessive waste of manpower and material resources during the detection process, and the manual cleaning of the powdered electrical-grade magnesium oxide on the detection tray by the staff, which greatly reduces the overall detection efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for detecting the impurity content of electrical-grade magnesium oxide, comprising a base and a housing, the housing being located on top of the base, a detection assembly being disposed within the housing, and a slide being slidably disposed on the inner wall of the housing, a detection slot being formed on the top of the slide, and collection boxes being disposed on both sides of the bottom of the slide, wherein a push plate is slidably disposed within the detection slot;

[0007] An arc-shaped end surface is provided on the front side of the push plate, and a through groove for the push plate to slide into is provided between the detection groove and the collection box. A shovel plate is provided for rotation on the side of the outer wall of the push plate away from the arc-shaped end surface, wherein the shovel plate is perpendicular to one side of the push plate in the normal state.

[0008] By adopting the above technical solution, the flatness of the surface on which the electrical-grade magnesium oxide is laid is achieved through the action of the push plate, and the front end of the push plate is arranged in an arc shape. During the movement, excess powdered electrical-grade magnesium oxide will flow to both sides of the arc end face, and at the same time, the baffle is opened by squeezing, so that the excess electrical-grade magnesium oxide in the detection groove falls into the collection box on one side. When the push plate is reset after the subsequent detection is completed, one end of the shovel plate will contact the bottom end of the detection groove. During the reset process, the shovel plate will push the tested electrical-grade magnesium oxide into the collection box on the other side.

[0009] The present invention is further configured such that a baffle is rotatably arranged in the through slot, and a torsion spring is connected between one side of the baffle and the through slot.

[0010] Preferably, under normal conditions, the baffle itself is in a closed state due to the action of the torsion spring, which effectively prevents the electrical-grade magnesium oxide in the collection box from floating upward, thereby improving the accuracy of its detection by the X-ray tube.

[0011] The present invention is further configured such that one end of the baffle is connected to a fixed gear, and a gear rod is meshed at the bottom end of the fixed gear, and one end of the gear rod is connected to a vertical plate, wherein the vertical plate is used to contact and squeeze the push plate.

[0012] Preferably, during the sliding process of the push plate, the vertical plate in the through groove will be squeezed, so that the vertical plate drives the gear rod at one end to slide to one side. During this process, the gear rod drives the fixed gear at the top to rotate, thereby causing the baffle to flip over. This makes it easier for the baffle itself to release the seal on the collection box during the process of the push plate sliding in, and when it slides out subsequently, the fixed gear itself flips over to seal the collection box again.

[0013] The present invention is further configured such that the detection assembly includes an X-ray tube and a detector body, the detector body is provided on the top of the shell, and an array of X-ray tubes is provided inside the shell, wherein the X-ray tube and the detector body are electrically connected.

[0014] Preferably, the electrical-grade magnesium oxide is evenly spread in the detection tank and then excited through an X-ray tube. The inner electrons of the elements in the sample will be excited by the X-ray tube, and the outer monads will jump to a low energy level, emitting characteristic fluorescence radiation. The fluorescence radiation is then collected by the detector body to form an energy spectrum. By analyzing the energy spectrum, the characteristic X-ray energy peaks of each element are identified, and the content of each element is calculated.

[0015] The present invention is further configured such that an electric slide is provided in the slide plate at the detection slot, wherein an electric slider is slidably provided in the electric slide, and one end of the electric slider is connected to the push plate.

[0016] Preferably, the cooperation between the electric slide and the electric slider facilitates the push plate to slide in the detection slot, and at the same time facilitates the staff to control the sliding direction of the push plate in the detection slot.

[0017] The present invention is further configured such that an array of tooth blocks is provided in the electric slide, and a special-shaped gear meshing with the electric slide is installed in the electric slide, wherein one end of the special-shaped gear passes through one side of the push plate and is connected to the shovel plate.

[0018] Preferably, when the electric slider is sliding in the electric slide groove, the tooth block will engage with the special-shaped gear in the electric slider, which will drive the special-shaped gear to rotate, thereby adjusting the angle of the shovel plate on one side of the push plate, so that the shovel plate is in different states when sliding in different directions.

[0019] The present invention is further configured such that a plurality of supporting legs are provided at the bottom of the base, and a blocking door is provided at the front end of the shell.

[0020] Preferably, the supporting legs can prevent dirt and impurities on the ground from eroding the outer wall of the base to a certain extent, and the setting of the baffle door facilitates the staff to visually observe the laying of the internal electrical grade magnesium oxide when the X-ray tube is inspected, thereby improving the overall practicality of the device.

[0021] The present invention is further configured such that the special-shaped gear is elastically arranged on one side of the electric slider, and under normal conditions the special-shaped gear will not mesh with the gear block.

[0022] As a preferred embodiment, after the subsequent inspection is completed, the special-shaped gear drives the shovel to rotate to clean the electrical grade magnesium oxide in its inspection groove. Subsequently, the special-shaped gear disengages from the meshing of the tooth block. At this time, the special-shaped gear is reset by its own elastic action, which facilitates the normal progress of the next set of inspections.

[0023] The present invention is further configured such that the collection box and the slide plate are detachably arranged, and the connection between the two is sealed.

[0024] Preferably, the detachable arrangement makes it easy for the staff to clean and replace the collection box, and the sealing arrangement between the two can prevent the powdered electrical grade magnesium oxide from leaking.

[0025] The present invention is further configured such that one side of the shovel plate is configured in a chamfered angle.

[0026] Preferably, the chamfered angle arrangement facilitates the sliding stability of the shovel plate itself during the process of the shovel plate cleaning the electrical grade magnesium oxide in the cleaning tank, thereby further improving the overall cleaning effect.

[0027] In summary, the present invention mainly has the following beneficial effects:

[0028] The present invention provides a slide plate in a housing, and a detection groove is provided on the slide plate. A worker pours pre-treated powdered electrical-grade magnesium oxide into the detection groove, and then drives a push plate to slide to one side through an electric slider. The push plate ensures the flatness of the surface on which the electrical-grade magnesium oxide is laid, and the front end of the push plate is arranged in an arc shape. During the movement, excess powdered electrical-grade magnesium oxide flows to both sides of the arc end surface, ensuring that the detection groove is fully covered with electrical-grade magnesium oxide, thereby preventing the inner wall of the subsequent detection groove from affecting the X-ray tube.

[0029] The present invention drives the push plate to slide into the through slot by an electric slider, and at the same time opens the baffle by squeezing, so that the excess electrical-grade magnesium oxide in the detection slot falls into a collection box on one side, so that it is collected uniformly, eliminating the need for manual recycling by staff, and preventing the surface flatness of the electrical-grade magnesium oxide from being affected during the manual recycling process, thereby further improving the accuracy of the overall detection;

[0030] The present invention enables the shovel plate and one side of the push plate to be set in a vertical state under the action of the special-shaped gear and the tooth block when the electric slider drives the push plate to slide. In this process, it is ensured that the sliding of the shovel plate will not affect the flatness of the electrical-grade magnesium oxide in the process of flattening and paving the electrical-grade magnesium oxide by the push plate, and after the subsequent inspection is completed and the push plate is reset, the tooth block will drive the special-shaped gear to reverse. At this time, one end of the shovel plate will contact the bottom end of the inspection groove. During the reset process, the shovel plate will push the tested electrical-grade magnesium oxide into the collection box on the other side. In this process, no manual cleaning is required, which speeds up the overall inspection efficiency and reduces the workload of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0045] The following describes an embodiment of the present invention based on its overall structure.

[0046] See also Figures 1-11The device for detecting the impurity content of electrical grade magnesium oxide shown in the figure comprises a base 1, a shell 2, a detection component, a collecting mechanism, a sliding mechanism and a laying mechanism, wherein a slide plate 8 is slidingly provided on the inner wall of the shell 2, and a detection groove 7 is opened on the top of the slide plate 8. The staff pours the pre-treated powdered electrical grade magnesium oxide into the detection groove 7 on the slide plate 8. Since an electric slide 10 is provided at the detection groove 7 in the slide plate 8, wherein an electric slider 14 is slidingly provided in the electric slide 10, and one end of the electric slider 14 is connected to the push plate 9, the push plate 9 is easily driven to slide in the detection groove 7 by the cooperation of the electric slide 10 and the electric slider 14. The flatness of the laying surface of the electrical grade magnesium oxide is ensured by the action of the push plate 9, and the front end of the push plate 9 is provided with an arc end face. During the movement, excess powdered electrical grade magnesium oxide will flow to both sides of the arc end face. In this process, it is ensured that the detection groove 7 is fully paved with electrical grade magnesium oxide.

[0047] Wherein, collecting boxes 6 are respectively provided on both sides of the bottom of the slide plate 8, and a through slot 11 for the push plate 9 to slide into is provided between the detection slot 7 and the collection box 6, and a baffle 13 is rotatably provided in the through slot 11, and a torsion spring is connected between one side of the baffle 13 and the through slot 11. Under normal conditions, the baffle 13 itself is in a closed state under the action of the torsion spring. Subsequently, when the push plate 9 pushes the powdered electrical-grade magnesium oxide to slide into the through slot 11 on one side, the baffle 13 is squeezed by the push plate 9 itself, so that the baffle 13 is in an open state at this time, and the excess electrical-grade magnesium oxide will fall into the collection box 6 on one side, so that it can be collected uniformly without the need for manual recycling by staff, and the surface flatness of the electrical-grade magnesium oxide is prevented from being affected during the manual recycling process, thereby further improving the accuracy of the overall detection;

[0048] In addition, a shovel plate 15 is provided for the rotation of the outer wall of the push plate 9 away from the arc-shaped end surface. Under normal conditions, the shovel plate 15 is perpendicular to one side of the push plate 9. In this process, it is ensured that in the process of flattening and laying the electrical grade magnesium oxide by the push plate 9, the sliding of the shovel plate 15 will not affect its flatness. After the subsequent inspection of the electrical grade magnesium oxide is completed, the electric chute 10 will drive the electric slider 14 to reset and slide. During this process, the push plate 9 follows the reset and slide. Since an array of tooth blocks 12 are provided in the electric chute 10, and a special-shaped tooth engaged with it is installed in the electric slider 14, Wheel 16, one end of the special-shaped gear 16 passes through one side of the push plate 9 and is connected to the shovel plate 15. When the electric slider 14 is located in the electric slide 10 and slides for resetting, the tooth block 12 will engage with the special-shaped gear 16 in the electric slider 14. During this process, the special-shaped gear 16 will be driven to rotate. At this time, one end of the shovel plate 15 will contact the bottom end of the detection groove 7. During the resetting process, the shovel plate 15 will push the tested electrical-grade magnesium oxide into the collection box 6 on the other side. During this process, no manual cleaning is required, which speeds up the overall detection efficiency and reduces the workload of the staff.

[0049] The electric slide 10 and the electric slider 14 are driven by a linear motor, which is a prior art for those skilled in the art. Its specific working principle is based on the principle of electromagnetic induction, which converts the motion of a rotary motor into linear motion. Unlike traditional rotary motors, linear motors do not require mechanical transmission devices (such as gears, screws, etc.) to convert rotary motion into linear motion, but directly generate linear propulsion force through electromagnetic force.

[0050] In the above embodiment, please refer to Figure 2 A detector body 3 is provided on the top of the shell 2, and an array of X-ray tubes 5 is provided inside the shell 2, wherein the X-ray tubes 5 and the detector body 3 are electrically connected. By evenly laying the electrical-grade magnesium oxide in the detection groove 7, and then exciting the electrical-grade magnesium oxide through the X-ray tube 5, the inner-shell electrons of the elements in the sample will be excited by the X-ray tube 5, and the outer-shell monads will jump to a low energy level, emitting characteristic fluorescence radiation. The fluorescence radiation is then collected by the detector body 3 to form an energy spectrum. By analyzing the energy spectrum, the characteristic X-ray energy peaks of each element are identified, and the content of each element is calculated.

[0051] In the above embodiment, please refer to Figure 2 and Figure 9The shaped gear 16 is elastically arranged on one side of the electric slider 14 (the elastic arrangement is realized by a torsion spring abutting between the electric slider 14 and the shaped gear 16). Under normal conditions, the shaped gear 16 contacts but does not mesh with the tooth block 12 for rotation. After the subsequent inspection is completed, the shaped gear 16 meshes with the tooth block 12 to drive the shovel plate 15 to rotate to clean the electrical grade magnesium oxide in its inspection groove 7. Subsequently, when the shaped gear 16 disengages from the meshing of the tooth block 12, the shaped gear 16 is reset by the torsion spring, which is convenient for the normal progress of the next group of inspections. A plurality of support legs are provided at the bottom of the base 1, and a baffle 4 is provided at the front end of the shell 2. The support legs can prevent the dirt and impurities on the ground from eroding the outer wall of the base 1 to a certain extent. The setting of the baffle 4 makes it convenient for the staff to visually observe the laying of the internal electrical grade magnesium oxide when the X-ray tube 5 is inspected, thereby improving the overall practicality of the device.

[0052] See also Figure 10 The device for detecting the impurity content of electrical-grade magnesium oxide shown in the figure has an overall structure similar to that of Example 1, wherein one end of the baffle 13 is connected to a fixed gear 17, and a gear rod 18 is meshed at the bottom end of the fixed gear 17, and a vertical plate 19 is connected to one end of the gear rod 18, wherein the vertical plate 19 is used to contact and squeeze each other with the push plate 9, and when the push plate 9 slides, it will squeeze the vertical plate 19 in the through groove 11, so that the vertical plate 19 drives the gear rod 18 at one end to slide to one side, and during this process, the gear rod 18 will drive the top fixed gear 17 to rotate, thereby causing the baffle 13 to flip over, so that the baffle 13 itself can release the sealing work of the collection box 6 during the sliding of the push plate 9, and when it slides out subsequently, the fixed gear 17 itself flips over and seals the collection box 6 again.

[0053] The present invention works specifically as follows: when in use, the staff pours the pre-treated powdered electrical-grade magnesium oxide into the detection groove 7 on the slide plate 8, and then drives the push plate 9 to slide to one side under the action of the electric slider 14. During the sliding process of the push plate 9, the flatness of the inner surface of the detection groove 7 of the electrical-grade magnesium oxide is ensured, and because one side of the push plate 9 is provided with an arc-shaped end surface, during the sliding process of the push plate 9, the excess electrical-grade magnesium oxide is moved to the two ends of the push plate 9 through its arc-shaped end surface, thereby ensuring that the detection groove 7 is full of electrical-grade magnesium oxide, preventing the subsequent inner wall of the detection groove 7 from affecting the X-ray tube 5, and the excess electrical-grade magnesium oxide will be discharged into the collection box 6 on one side under the action of the push plate 9, without the need for manual processing;

[0054] At the same time, a shovel plate 15 is rotatably provided on the other side of the push plate 9. When the push plate 9 slides to one side to push the electrical-grade magnesium oxide, the shovel plate 15 itself is arranged perpendicular to one side of the push plate 9 under the action of the special-shaped gear 16 and the tooth block 12. In this process, when the push plate 9 is evenly laid on the surface of the electrical-grade magnesium oxide, the shovel plate 15 itself will not affect the flatness of the electrical-grade magnesium oxide. Subsequently, after the X-ray tube 5 and the detector body 3 are coordinated for detection, the electric slider 14 will drive the push plate 9 to reset. During this process, the tooth block 12 will drive the special-shaped gear 16 to reverse. At this time, one end of the shovel plate 15 will contact the bottom end of the detection groove 7. When the push plate 9 follows the reset sliding, the shovel plate 15 will discharge the detected electrical-grade magnesium oxide through the through slot 11 into the collection box 6 on the other side. No manual cleaning is required in this process.

[0055] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
