Description

Technical Field

[0001] This utility model belongs to the field of precious metal processing technology, and specifically relates to a waste recycling device for precious metal processing. Background Technology

[0002] In the field of precious metal processing technology, precious metal processing debris recovery devices are specialized equipment for the recovery and processing of debris generated during precious metal processing. Precious metal processing is a highly precise process involving various processing methods, such as cutting, carving, and polishing, which inevitably generate a large amount of precious metal debris.

[0003] In the production and processing of precious metals, a certain amount of precious metal debris is inevitably generated due to a series of delicate processes such as cutting, grinding, and polishing. Although these debris vary in shape and size, they all contain extremely high economic value. Traditional production and processing methods often ignore the potential value of these debris and treat them directly as waste, which is undoubtedly a huge waste of resources. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-5 This utility model provides the following technical solution: a scrap recycling device for precious metal processing, comprising: a recycling frame 1, a protective cover 2 on the top of the recycling frame 1, a rotating shaft 3 horizontally connected to the upper end of the recycling frame 1, a top plate 4 rotatably connected to the surface of the rotating shaft 3, an insert plate 5 inserted into the surface of the bottom vertical plate of the top plate 4, the front end of the insert plate 5 horizontally connected to the front end surface of the recycling frame 1, a limiting plate 6 above the front insert plate 5 of the recycling frame 1, a rubber protrusion on the top of the insert plate 5 being engaged at the bottom of the limiting plate 6, a fixing plate 7 fixedly connected to the bottom of the inner wall of the recycling frame 1, a bolt assembly 8 threadedly connected to the lower end of the support frame 9 through the side wall of the fixing plate 7, a receiving box 10 supported by the surface of the top disc of the support frame 9, the surface of the receiving box 10 being sleeved on the inner wall of the recycling frame 1, an installation pipe 11 welded to the top of the inner wall of the protective cover 2, the bottom of the installation pipe 11 being threadedly connected to the top vertical rod of the spring 12, a cleaning brush 13 connected to the surface of the bottom vertical rod of the spring 12, and the bottom of the cleaning brush 13 abutting against the top of the recycling frame 1.

[0023] Preferably, the recycling rack 1, the rotating shaft 3 and the top plate 4 form a rotating connection structure, and two sets of rotating shafts 3 and top plates 4 are symmetrically distributed at the top opening of the recycling rack 1.

[0024] In actual use, the top plate 4 rotates downward under the action of gravity using the connected shaft 3, making it easier to collect the debris on it.

[0025] Preferably, the bottom of the top plate 4 is provided with two sets of vertical plates, and the side walls of the vertical plates are provided with rectangular grooves, and the shape and size of the rectangular grooves are adapted to the insert plate 5.

[0026] In practical use, the rectangular slots on the bottom vertical plate of the top plate 4 facilitate the insertion of the insert plate 5, thereby fixing the position of the two top plates 4.

[0027] Preferably, the protective cover 2 has a rectangular observation window on the top and two through slots at the front end, with a conical rubber sleeve at the front end of each through slot.

[0028] In practical use, the circular through-slot and conical rubber sleeve at the front end of the protective cover 2 can be used to fit the operator's hand, thus facilitating the processing of precious metals in the enclosed environment formed by the protective cover 2 and the recycling rack 1.

[0029] Preferably, the top of the receiving box 10 has an inverted trapezoidal groove, and the bottom of the receiving box 10 has a cylindrical groove, and the shape and size of the groove are adapted to the top disc of the support frame 9.

[0030] In practical use, the support frame 9 is used to fix the position of the receiving box 10. At the same time, after the processing is completed, the support frame 9 can be easily disassembled to take out the receiving box 10 placed on the inner wall of the recycling rack 1.

[0031] Preferably, the mounting tube 11, spring 12 and cleaning brush 13 form a threaded connection structure.

[0032] In actual use, the cleaning brush 13 is pulled so that it can move elastically at the bottom of the mounting tube 11 via the connected spring 12, and springs back and retracts directly below the mounting tube 11 after use.

[0033] Working principle: During precious metal processing, the precious metal parts requiring precision machining are placed above the top plate 4 for processing. Simultaneously, the circular groove and conical rubber sleeve at the front of the protective cover 2 engage with the operator's hand, facilitating processing of precious metals in a confined environment. Processing debris falls onto the top plate 4, while flying debris is blocked and intercepted by the protective cover 2. After processing, pulling the insert plate 5 engaged with the limiting plate 6 disengages it from the two top plates 4. Simultaneously, the top plate 4 rotates downwards under gravity via the connected shaft 3, causing the debris to slide into the collection box 10 below for collection. Any remaining metal debris on the surfaces of the top plate 4 and protective cover 2 can be cleaned by the cleaning brush 13. During sweeping, the circular groove at the front of the protective cover 2 facilitates gripping the cleaning brush 13, and the spring 12 connected to the top of the cleaning brush 13 pulls the cleaning brush 13 to move it further away, thereby cleaning the metal debris. After sweeping, the spring 12 fixed on the mounting tube 11 can be unscrewed to clean the remaining metal powder. During cleaning, a suitable chemical solvent can be used to penetrate into the gaps, dissolve the adhering substances, and loosen the precious metal debris. It can then be recovered by rinsing or wiping. After collection, the bolt assembly 8 fixed between the fixing plate 7 and the support frame 9 can be unscrewed to disassemble the support frame 9, thereby facilitating the downward movement of the collection box 10 supported in the recycling rack 1 for easy collection of metal debris.

[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
