Description

Technical Field

[0001] This invention discloses an integrated precious metal processing machine, particularly an integrated precious metal granulation and ingot casting machine, which belongs to the technical field of precious metal processing equipment. Background Technology

[0002] Precious metal ingots are physical objects made from precious metal raw materials such as gold, silver, platinum, and palladium through processes such as melting, casting, and cooling, and are formed into fixed shapes (such as bars, squares, and circles). They are an important form of precious metal storage, trading, and industrial applications.

[0003] Precious metal granulation is a technology that processes precious metal raw materials (powder, fragments, or molten state) such as gold, silver, platinum, and palladium into uniform particles with controllable particle size through specific processes. Its core purpose is to meet the refined requirements of precious metal forms in fields such as electronics, jewelry, and medicine, while also considering the convenience of recycling. Different applications have vastly different requirements for the particle size (from micrometers to millimeters), purity, and sphericity of precious metal particles, leading to different process choices. Commonly used precious metal granulation is wet granulation, which involves rapidly cooling molten precious metal liquid through small holes in a mold into a cooling liquid to form particles. These particles typically have a diameter of 2-5 mm, high sphericity, and a smooth surface, and are commonly used in electronic pastes (such as silver particles for chip wires) and precious metal powders for thick-film circuits.

[0004] Precious metal ingot casting and granulation are two different processing techniques and processes. It's usually reasonable to use separate equipment for both. Large factories require continuous granulation and ingot casting daily, with production capacity measured in tons. Integrated granulation and ingot casting machines are designed for small-batch users, producing only 5kg of granules and casting 1kg ingot per day. For small-batch users, purchasing two separate machines would be very costly. Summary of the Invention

[0046] In this embodiment, the granulation mechanism support arm includes an upper support arm 47 and a lower support arm 48. In specific implementations, one or more support arms can be provided according to actual needs. The upper support arm 47 is fixedly installed on the upper side of the granulation cylinder 41. An upper oil-free bushing 471 is embedded within the upper support arm 47. The upper oil-free bushing 471 is fitted onto the second support rod 16. In this embodiment, the upper oil-free bushing 471 is located above the second upper fixing ring 161.

[0050] In this embodiment, a first water inlet valve 461 is installed at the lower part of the granulation cylinder 41, and a second water inlet valve 462 is installed at the upper part of the granulation cylinder 41 for injecting water into the granulation cylinder 41. A circulating water counterflow port 463 is welded to the top of the granulation cylinder 41, and the cooling water in the granulation cylinder 41 cools the material in the granulation cylinder 41.

There is a plug at the bottom of the granulation graphite crucible with several small holes. After the raw material melts into liquid in the crucible, the cylinder drives the stopper rod to rise and drip into the granulation cylinder 41 through the small holes to form granules.

[0052] In this embodiment, a discharge gate pivot 452 is fixedly installed next to the discharge port of the granulation cylinder 41.

A discharge gate engaging shaft 453 is also fixedly installed next to the discharge port of the granulation cylinder 41. A discharge gate engaging groove 456 is opened at a corresponding position on the granulation discharge gate 45. When the granulation discharge gate 45 is closed, the discharge gate engaging groove 456 engages with the discharge gate engaging shaft 453. In this embodiment, a discharge gate limiting shaft 454 is also fixedly installed next to the discharge port of the granulation cylinder 41. A discharge gate limiting groove 457 is opened at a corresponding position on the granulation discharge gate 45, which can limit the rotation of the granulation discharge gate 45. In this embodiment, a first fixing nut 458 is installed on the discharge gate pivot 452, and a second fixing nut 459 is installed on the discharge gate snap-fit ​​shaft 453. The granulation discharge gate 45 is locked by the first fixing nut 458 and the second fixing nut 459.

[0053] This invention can be used in two ways: 1. Casting: Rotate the casting mechanism 3 along the first support rod 15, causing the ingot clamping piece 36 to engage with the second support rod 16. The ingot ball 361 acts as a pressure point, maintaining the relative fixation between the casting mechanism 3 and the second support rod 16. Activate the lifting cylinder 17 to push the casting mechanism 3 upwards, causing its upper surface to adhere tightly to the heating mechanism 2. Activate the heating mechanism 2 to heat the internal material until it melts. Then, pour the material into the ingot mold 34 for cooling and shaping before removing it.

[0054] II. Granulation: Rotate the granulation mechanism 4 along the second support rod 16 to engage the granulation clamping piece 44 with the first support rod 15. The granulation ball 441 presses against the granulation mechanism 4 to maintain relative fixation between the granulation mechanism 4 and the first support rod 15. Start the lifting cylinder 17 to push the granulation mechanism 4 upward, so that the upper surface of the granulation mechanism 4 is pressed against the heating mechanism 2. Start the heating mechanism 2 to heat the material inside until it melts. Then, the cylinder drives the stopper rod to lift, and the molten metal drips through the graphite plug into the granulation cylinder 41 filled with cooling water. Observe the material accumulation in the granulation cylinder 41 through the granulation observation window 43. When the set position is reached, open the granulation discharge door 45 to discharge the material particles.

[0055] This invention allows for free switching between the ingot casting mechanism and the granulation mechanism, achieving the combined functions of ingot casting and granulation, thus integrating the two into one unit. This not only reduces the user's operating and maintenance costs but also significantly reduces its footprint.
