Description

Technical Field

[0001] This utility model relates to the field of melting equipment technology, specifically to a sample melting device for determining gold and platinum content. Background Technology

[0002] Melting equipment is a type of equipment used to heat solid substances to a molten state. It is mainly used to melt materials such as metals, plastics, glass, and ceramics for processing, manufacturing, or research. Melting equipment has a wide range of applications in various industries and fields.

[0003] Chinese Patent CN111982888A discloses a method for determining gold and platinum in a smelting test liquid sample, comprising the following steps: weighing 35g of anhydrous sodium carbonate, 80g of lead oxide, 13g of borax, 9g of silicon dioxide, and 3.5g of flour into a clay crucible and stirring evenly; weighing the total mass of the entire test liquid sample, performing dry filtration on the solution, weighing the mass of the filtrate, and taking the weight of the remaining solution adhering to the filter paper and the residue after filtration as the filter residue; weighing three or more portions of the filtrate (1.00-2.50g each) and transferring them to the prepared and stirred clay crucibles respectively; transferring all the filter residue to the corresponding clay crucibles, covering with a 10mm thick covering agent; melting, blowing, granulation and cleaning, silver replenishment and re-blowing, gold separation, and determination. This invention can quickly and accurately determine the gold and platinum content in a smelting test liquid sample, solving the problems of uneven data and low efficiency in the determination of gold and platinum in smelting test liquid samples, and the method has good accuracy.

[0004] In existing technologies, when multiple samples need to be processed simultaneously to improve testing efficiency, multiple crucibles need to be placed in melting equipment or melting furnaces. However, when performing gold-platinum determination, the melting equipment needs to be preheated to an appropriate temperature before the crucibles are placed in. Due to heat radiation and heat conduction, the staff cannot spend a long time adjusting the position of the crucibles when placing them in the melting equipment. This may cause errors in the uniformity of heating of the crucibles after they are placed in the melting equipment, affecting the accuracy of the test. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a sample melting device for determining gold and platinum content.

[0006] The technical solution of this utility model is as follows: A sample melting device for determining gold and platinum content includes a melting device body with a rotatably connected sealing door; a support assembly connected to the melting device body, the support assembly including a fixed plate, a movable plate, and a linkage assembly, the fixed plate being connected to the melting device body, the fixed plate having a sliding groove, the movable plate being slidably connected to the sliding groove, the sliding groove having a groove for accommodating a crucible, and the linkage assembly being connected to the sealing door and the movable plate respectively; in the use state, the opening and closing of the sealing door drives the linkage assembly and the movable plate to move synchronously, the movable plate sliding out along the sliding groove to send the crucible out of the melting device body; a protective assembly connected to the melting device body; when the sealing door is opened, the protective assembly simultaneously enters the use state, the movable end of the protective assembly moves horizontally synchronously with the movable plate, and when the sealing door is closed, the protective assembly enters the initial state, the movable end of the protective assembly is horizontally retracted into the melting device body.

[0007] Preferably, the support assembly further includes a positioning plate connected to the movable plate.

[0008] Preferably, the linkage component includes a rotating rod rotatably connected to the cabinet door, with a protrusion connected to the rotating rod; a support plate connected to the positioning plate, the positioning plate being perpendicular to the support plate, and a notch being provided on the support plate, the notch engaging with the protrusion.

[0009] Preferably, a limit block is connected to the sealing door, and the limit block is located below the rotating rod.

[0010] Preferably, the rotating rod consists of a fixed cylinder and a movable rod. The fixed cylinder is rotatably connected to the sealing door, and the movable rod is slidably connected inside the fixed cylinder. One end of the movable rod is provided with a limiting protrusion.

[0011] Preferably, the protective component includes a protective plate that is slidably connected to a receiving groove on the main body of the melting equipment; a connecting plate that is connected to the end of the protective plate away from the main body of the melting equipment, and a limiting groove is provided on the connecting plate; and a linkage rod that is connected to the sealing door, the linkage rod being slidably connected to the limiting groove, and a stop block being connected to the end of the connecting rod near the limiting groove.

Two rotating plates are rotatably connected in the placement slots, and the two ends of the elastic element are respectively connected to the placement slots and the rotating plates.

[0014] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0015] In this invention, the opening and closing of the sealing door can simultaneously drive the support component and the protective component to move. The moving plate of the support component can be moved out of the main body of the melting equipment to facilitate the placement and adjustment of the crucible containing the sample by the staff. The moving plate is a certain distance away from the heat source, which reduces the impact of heat radiation and heat conduction on the staff and increases their field of vision and adjustable angle. At the same time, the protective plate of the protective component will also extend out of the main body of the melting equipment. The protective plate is located below the moving plate and has a larger area than the moving plate. When items fall on the moving plate, it can play a certain role in blocking and protecting them, preventing high-temperature molten metal from falling to the ground and causing harm to the surrounding environment and personnel.

[0021] Example 1

[0022] like Figures 1-4As shown, this utility model proposes a sample melting device for determining gold and platinum content, including a melting device body 1, a sealing door 2, a support assembly, and a protective assembly.

[0023] Example 2

[0024] like Figures 1-3 As shown, the sample melting device for determining gold and platinum content proposed in this utility model, compared with Embodiment 1, also describes the detailed structure of the support component. The support component also includes a positioning plate 5, which is connected to the moving plate 4.

[0025] The linkage assembly includes a rotating rod 7, a protrusion 8, and a support plate 9. The rotating rod 7 is rotatably connected to the sealing door 2, and the protrusion 8 is connected to the rotating rod 7. The support plate 9 is connected to the positioning plate 5. The positioning plate 6 is perpendicular to the support plate 9. A notch 6 is provided on the support plate, and the notch 6 engages with the protrusion 8.

[0026] In an optional embodiment, a limiting block 10 is connected to the sealing door 2, and the limiting block 10 is located below the rotating rod 7; when the limiting block 10 is located below the rotating rod 7, it can limit the rotation range of the connecting rod 5, so that it can only rotate upward, and keep the rotating rod 7 parallel to the support plate 9.

[0027] In an optional embodiment, the rotating rod 7 consists of a fixed cylinder 11 and a movable rod 12. The fixed cylinder 11 is rotatably connected to the sealing door 2, and the movable rod 12 is slidably connected inside the fixed cylinder 11. One end of the movable rod 12 is provided with a limiting protrusion 13.

[0028] Example 3

[0029] like Figure 1 , Figure 3 , Figure 4As shown, the present invention proposes a sample melting device for determining gold and platinum content. Compared with Embodiment 2, this embodiment also describes the detailed structure of the protective component. The protective component includes a protective plate 14, a connecting plate 15, a connecting rod 17, and a stop block 18. The protective plate 14 is slidably connected to a receiving groove opened on the melting device body 1. The connecting plate 15 is connected to the end of the protective plate 14 away from the melting device body 1. A limiting groove 16 is opened on the connecting plate 15.

[0030] In an optional embodiment, the connecting plate 15 consists of a mounting plate 19 and a movable plate 20. The mounting plate 19 is connected to the protective plate 14. A limiting groove 16 is provided on the mounting plate 19 to slide and connect with the limiting block 10. The protective plate 14 is detachably connected to the mounting plate 19. A through groove for the linkage rod 17 to pass through is provided on the protective plate 14.

[0031] In an optional embodiment, the protective plate 14 is composed of a horizontal plate 21, a rotating plate 22 and an elastic element 23. The horizontal plate 21 is connected to the connecting plate 15. The horizontal plate 21 is provided with symmetrically arranged placement slots. The two rotating plates 22 are rotatably connected in the placement slots. The two ends of the elastic element 23 are respectively connected to the placement slots and the rotating plates 22.

[0032] The linkage rod 17 is connected to the sealing door 2. The linkage rod 17 is slidably connected to the limiting groove 16. A stop block 18 is connected to the end of the linkage rod 17 near the limiting groove 16.

[0033] In an optional embodiment, when the operator places the crucible containing the sample into the main body 1 of the melting equipment, the sealing door 2 is opened. The sealing door 2 rotates around its hinge point, and simultaneously the rotating rod 7 and the connecting rod 17 connected to the sealing door 2 also rotate. When the rotating rod 7 rotates, it drives the support plate 9 and the positioning plate 5 to move through the engagement of the protrusion 8 and the notch on the support plate 9, thereby moving the moving plate 4 horizontally from the fixed plate 3 and removing it from the main body 1 of the melting equipment for the operator to place or retrieve the crucible. While the rotating rod 7 rotates, since the rotating rod 7 is composed of a fixed cylinder 11 and a moving rod 12, its length can extend to drive the moving plate 4 to move; while the connecting rod 17 will make an arc motion. The connecting rod 17 and the stop 18 slide in the limiting groove 16 on the connecting plate 15, and its arc motion... While moving, the connecting plate 15 can be moved horizontally through contact with the limiting groove 16. After the connecting plate 15 is removed from the receiving groove, it is located below the moving plate 4, which can prevent items on the moving plate 4 from falling to the ground and causing injury to people around. When the sealing door 2 is closed after the items are placed or taken out, the sealing door 2 rotates and drives the rotating rod 7 and the connecting rod 17 to rotate. As the rotation proceeds, the fixed cylinder 11 and the moving rod 12 push the support plate 9 and the moving plate 4 to move through the protrusion 8. At the same time, the moving rod 12 will retract into the fixed cylinder 11, so that the rotating rod 7 will not cause obstruction when the sealing door 2 is close to the moving plate 4. The connecting rod 17 also slides along the limiting groove 16 while making arc motion, retracting the protective plate 14 into the receiving groove. At the same time, the rotating plate 22 will also be restricted by the receiving groove to rotate and compress the elastic element 23.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
