The powder scraping slide is screwed on the outer side of the circumference of the reciprocating screw. A scraper is installed at the lower end of the powder scraping slide. This precious metal waste recycling device uses a filter plate to filter precious metals. However, a single filter plate is difficult to fully separate electroplating wastewater from precious metal powder, resulting in an unsatisfactory separation effect. Utility Model Content

[0010] Preferably, the cross-sectional shape of the insert is set to an inverted T-shape, and the collection box is detachably connected to the heating base through the insert, which facilitates the installation of the collection box and improves the convenience of loading and unloading.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a physical separation and recycling device for precious metal waste, including a sedimentation tank 3, a water pump installed on the sedimentation tank 3, the water pump's delivery end being connected to the bottom of one end of the separation tank 1, enabling electroplating wastewater to be sent to the bottom of the separation tank 1, a separation tank 1 located on one side of the sedimentation tank 3, a multi-stage separation mechanism 2 inside the separation tank 1, multiple switch doors 5 on the separation tank 1, and a liquid level monitoring mechanism 4 installed on the top of the separation tank 1. The multi-stage separation mechanism 2 can perform multi-stage separation of electroplating wastewater and prevent clogging, while simultaneously collecting precious metal powder, effectively improving the separation effect.

[0023] The multi-stage separation mechanism 2 includes a rotating shaft 201, with a drive motor 202 fixedly connected to the end of the rotating shaft 201. Multiple circular filter plates 203 are mounted on the rotating shaft 201. Filtration is performed using the lower half of the circular filter plates 203, which rotate continuously for cleaning, ensuring the filtration section of the circular filter plates 203 is always clean, preventing clogging, and improving filtration effect and efficiency. The rotating shaft 201 is rotatably connected to the inner wall of the separation box 1. The rotating shaft 201 is detachably connected to the multiple circular filter plates 203 via bolts, allowing for easy disassembly, assembly, and replacement of the circular filter plates 203. A mounting bracket 204 is provided on the top of one side of each circular filter plate 203. A cleaning seat 205 is fixedly connected to the bottom of the mounting bracket 204. A brush plate 206 is mounted at the end of the cleaning seat 205, with multiple air holes and bristles 207. An air duct 208 is connected to the end of the cleaning seat 205, and the interior of the cleaning seat 205 communicates with the air holes on the brush plate 206. A fan is connected to the cleaning seat 205 via the air duct 208, which can use the fan to discharge a gentle breeze through the air hole to assist in cleaning the bristles 207 and improve the cleaning effect. The bottom of the cleaning seat 205 is equipped with a heating seat 209. One end of the heating seat 209 is welded to the inner wall of the separation box 1, and the other end of the heating seat 209 is located on the side of the switch door 5, which can be easily opened to remove the collection box 211 on the heating seat 209. The heating seat 209 is equipped with multiple electric heating wires 210. The top of the heating seat 209 is equipped with a collection box 211. The bottom of the collection box 211 is fixedly connected to a plug 212. The cross-sectional shape of the plug 212 is set as an inverted T. The collection box 211 is detachably connected to the heating seat 209 through the plug 212, which can facilitate the installation of the collection box 211 and improve the convenience of loading and unloading. A guide plate 213 is provided on one side of the top of the collection box 211, which can facilitate the guidance of precious metal powder and allow it to fall into the collection box 211.

[0024] Please see Figure 1 and Figure 4 The liquid level monitoring mechanism 4 includes a base 401 and an ultrasonic level gauge 403. The ultrasonic level gauge 403 emits ultrasonic pulses, which are reflected back when they encounter the surface of the measured medium. Part of the reflected echoes are received by the same transducer (probe) and converted into electrical signals. The instrument can calculate the distance from the transducer to the surface of the measured medium by measuring the time difference from the emission to the reception of the ultrasonic wave, thereby determining the liquid level. An external threaded pipe 402 is fixedly connected to the top of the base 401, and an installation threaded sleeve 404 is rotatably connected to the bottom of the ultrasonic level gauge 403. The installation threaded sleeve 404 matches the external threaded pipe 402, and the liquid level inside the separation tank 1 can be monitored in real time through the ultrasonic level gauge 403 to avoid excessive wastewater input. Furthermore, the quick installation of the installation threaded sleeve 404 and the external threaded pipe 402 can effectively improve the convenience of installation and maintenance.

[0025] During operation, the water pump feeds electroplating wastewater into the lower half of the separation tank 1. The drive motor 202 drives the rotating shaft 201 to rotate, which in turn drives multiple circular filter plates 203 to rotate. This allows the lower half of the circular filter plates 203 to perform filtration, and the filtered portion rotates upwards to rub against the bristles 207 on the brush plate 206, brushing off the precious metal powder. At the same time, a small amount of air is discharged from the vents to assist in cleaning and prevent the circular filter plates 203 from clogging. The precious metal powder falls into the collection box 211, where the electric heating wire 210 heats the collection box 211 to evaporate excess water. This multi-stage separation of the electroplating wastewater prevents clogging and collects the precious metal powder, effectively improving the separation effect.
