Description

Technical Field

[0001] This utility model relates to the field of precious metal processing technology, and in particular to a precious metal recycling device. Background Technology

[0002] In existing precious metal (such as gold and silver) recycling processes, manual operation is typically employed. Specifically, operators must first open the lid of a cardboard box, remove the precious metal, and then melt it in a furnace. After melting, the metal is poured into a cooling device to cool, ultimately completing the recycling process. The entire process relies entirely on manual labor. However, this manual method has many drawbacks. For example, due to the high economic value of precious metals, there is a risk of theft during manual operation. This could not only lead to economic losses for the company but also disrupt the normal operation of precious metal recycling. Furthermore, manual recycling is inefficient and cannot meet the growing demand for precious metal recycling. Therefore, the existing manual operation method is no longer sufficient to meet the development needs of the precious metal recycling industry and urgently requires improvement.

[0010] Please see Figure 1-23 As shown, one embodiment of this utility model provides a precious metal recycling device, specifically including a frame. The frame is equipped with a material handling and tray changing device 10, a first weighing device 20, a conveying device 22, a melting device 40, a cooling device 60, and a second weighing device 21. The material handling and tray changing device 10 opens the lid of a cardboard box a80 and takes out a second tray a81 containing precious metals from the cardboard box a80. The material handling and tray changing device 10 can supply a first tray a71 and transfer the first tray a71 to the first weighing device 20 for weighing. The material handling and tray changing device 10 transfers the precious metals from the second tray a81 to the first tray a71. The material handling and tray changing device 10 then transfers the first tray containing precious metals to the first tray a71. The first pallet a71 is transferred to the first weighing device 20 for weighing. After weighing, the material handling and pallet changing device 10 transfers the first pallet a71 containing the precious metal to the conveying device 22. In this embodiment, the conveying device 22 can be a belt conveyor line. The conveying device 22 conveys the first pallet a71 containing the precious metal to the melting device 40. The melting device 40 takes out the precious metal from the first pallet a71 in the conveying device 22, melts it, and then transfers it to the cooling device 60 for cooling. The second weighing device 21 takes out the cooled precious metal from the cooling device 60, weighs it, and then transfers it to the same first pallet a71 conveyed by the conveying device 22. In the aforementioned scheme, the various devices cooperate to transfer the precious metal from the second tray a81 to the first tray a71 and place it in the first weighing device 20 for weighing. The weight of the first tray a71 can be known in advance by weighing it through the first weighing device 20. When the first weighing device 20 weighs the first tray a71 already loaded with precious metal, it can know the first weight of the precious metal before melting. The second weighing device 21 takes out the cooled precious metal from the cooling device 60 and weighs the melted precious metal a second time to know the second weight of the precious metal after melting. Subtracting the second weight of the precious metal after melting from the first weight before melting gives the loss of precious metal during the recycling process. This loss value is used to feed back the actual operating status of the precious metal recycling equipment. If there is an abnormality, the machine is stopped in time for correction.
