Description

Technical Field

[0001] The utility model relates to the technical field of precious metal extraction and smelting, in particular to a smelting device for extracting precious metals from discarded three-way catalytic converters. Background Art

[0002] Precious metals are a general term for precious metals and rare metals. Precious metals mainly refer to metals such as gold, silver, and platinum. The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. When the three-way catalytic converter is discarded, directly discarding it will cause serious waste of resources. Therefore, usable metals will be extracted from it for re-smelting to become renewable resources.

[0003] When precious metals are extracted and smelted for a long time, the temperature of the smelting furnace will gradually rise. At present, when smelting is completed, the molten metal liquid is mostly taken out manually. The high temperature will cause burns, thereby reducing safety issues. Utility Model Content

The smelting device body 1 includes a bearing base 2, a supporting vertical plate 3 is fixedly installed on the right side of the bearing base 2, a smelting furnace 4 is arranged above the bearing base 2, a sealing unit is arranged above the smelting furnace 4, and unloading units are arranged on both sides of the smelting furnace 4. The unloading unit includes a bearing horizontal plate 34 arranged on the outer surfaces of both sides of the supporting vertical plate 3, and a bearing The other end of the horizontal plate 34 extends on the outer surfaces of both sides of the smelting furnace 4. The outer surfaces of both sides of the supporting vertical plate 3 are fixedly installed with electric telescopic columns 35 above the bearing horizontal plate 34. The other end of the electric telescopic column 35 is fixedly connected with a toothed plate 36. The bottom end of the toothed plate 36 is meshingly connected with a rotating gear 37. The inside of the rotating gear 37 is fixedly sleeved with a driving rod 38. The inner end of the driving rod 38 is fixedly connected to the outer surfaces of both sides of the smelting furnace 4, and the outer end of the driving rod 38 is rotatably connected to the inside of the other end of the bearing horizontal plate 34.

[0027] Furthermore, the tooth plate 36 is moved forward by the extension and retraction of the electric telescopic columns 35 on both sides. The forward movement of the tooth plate 36 causes the rotating gear 37 to rotate. The rotating gear 37 drives the driving rod 38 to rotate accordingly, thereby causing the smelting furnace 4 to tilt to one side, so as to facilitate the discharge of the precious metal liquid smelted inside.

[0028] Example 2

[0029] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, limiting rings 21 are fixedly installed on both the front and rear sides of the top of the supporting base 2, a limiting groove 22 is provided inside the limiting ring 21, and a limiting rod 46 is located on the front end of the front and rear bottom of the smelting furnace 4 above the supporting base 2, and the limiting rod 46 is slidably connected to the inside of the limiting groove 22.

[0030] Furthermore, when the smelting furnace 4 is tilted, the limiting rods 46 on both sides of the bottom end slide inside the limiting grooves 22 to achieve the limiting effect.

[0031] Example 3

[0032] like Figure 1-5As shown, on the basis of Examples 1-2, the utility model provides a technical solution: preferably, the sealing unit includes a top plate 31 supporting the top vertical plate 3, a hydraulic cylinder 32 is fixedly installed on the top of the top plate 31, a hydraulic rod 33 is fixedly installed on the output end of the hydraulic cylinder 32, an upper cover plate 41 is fixedly installed on the other end of the hydraulic rod 33, a sealing ring 42 is fixedly installed on the bottom end of the upper cover plate 41, upper half rings 43 are fixedly installed on the front and rear outer surfaces of the upper cover plate 41, lower half rings 44 are fixedly installed on the top ends of the front and rear outer surfaces of the smelting furnace 4, arc-shaped fixing rings 45 are rotatably installed on both sides of the lower half ring 44, and the arc-shaped fixing rings 45 are rotatably sleeved on the top outer surface of the upper half ring 43.

[0033] Furthermore, the hydraulic rod 33 is extended and retracted by the output end of the hydraulic cylinder 32, so that the upper cover plate 41 is closely fitted on the top of the smelting furnace 4, and then the arc-shaped fixing rings 45 on the front and rear sides are rotated upward to sleeve on the outer surface of the upper half ring 43, so that the connection of the upper cover plate 41 is fixed, and at the same time, the smelting furnace 4 is sealed during smelting to prevent heat energy from dissipating outward.

[0034] The following is a detailed description of the working principle of the smelting device for extracting precious metals from discarded three-way catalytic converters.

[0035] like Figure 1-5 As shown, when in use, the discarded three-way catalytic converter is thrown into the interior of the smelting furnace 4, and then the output end of the hydraulic cylinder 32 drives the hydraulic rod 33 to extend and retract, so that the upper cover plate 41 is closely attached to the top of the smelting furnace 4, and then the arc-shaped fixing rings 45 on the front and rear sides are turned upward to sleeve on the outer surface of the upper half ring 43, so that the connection of the upper cover plate 41 is fixed, and at the same time, the smelting furnace 4 is sealed during smelting to prevent heat energy from dissipating outward. After smelting is completed, the fixation is released, and then the tooth plate 36 is driven forward by the extension and retraction of the electric telescopic columns 35 on both sides. The forward movement of the tooth plate 36 causes the rotating gear 37 to rotate, and the rotating gear 37 drives the driving rod 38 to rotate accordingly, so that the smelting furnace 4 is tilted to one side, which is convenient for the precious metal liquid smelted inside to be discharged outward. When the smelting furnace 4 is tilted, the limit rods 46 on both sides of the bottom slide in the inside of the limit groove 22 to achieve the limit effect.
