Description

Technical Field

[0001] This utility model relates to the field of gold and silver loaded carbon recovery equipment, specifically to a gold and silver loaded carbon separation and recovery device. Background Technology

[0002] After the gold and silver recovery process via cyanidation of whole peat slurry, the gold and silver-loaded carbon needs to be separated and recovered. Traditionally, a bridge screen separates most of the gold and silver-loaded carbon, followed by a small linear vibrating screen to separate and recover worn-down small carbon particles, ensuring full recovery. However, in actual operation, if the bridge screen separation becomes clogged, a large amount of gold and silver-loaded carbon slurry will quickly flow to the small linear vibrating screen. Due to insufficient processing capacity, the small vibrating screen causes the slurry to flow into the tailings pipe, resulting in the loss of valuable gold and silver elements and potentially causing blockages in the tailings pipe, leading to accidents.

[0003] To address the aforementioned issues, this invention proposes a gold and silver-loaded carbon fragment recovery device to resolve the loss of gold and silver-loaded carbon caused by the overflow of slurry during the initial bridge screen separation, ensuring that the gold and silver-loaded carbon (including fragmented carbon) is fully separated and recovered. Utility Model Content

[0004] This invention provides a device for separating and recovering gold and silver loaded carbon.

[0005] The specific technical solution is as follows:

[0006] A gold-silver-loaded carbon separation and recovery device includes a feed pipe and a vibrating screen. A collection trough is provided on one side of the vibrating screen, and the discharge port of the vibrating screen is directly opposite the open opening at the top of the collection trough. A separation net is connected to the upper inner wall of the collection trough, and a liquid outlet communicating with a waste liquid ditch is opened on one side of the bottom of the collection trough.

[0007] Furthermore, preferably, a rinsing water pipe is connected to one side of the collection tank, and the rinsing water pipe is positioned higher than the separation net.

[0008] Furthermore, preferably, a flow meter is installed on the feed pipe, and a solenoid valve is installed on the flushing water pipe. Both the flow meter and the solenoid valve are electrically connected to the controller, and the controller is electrically connected to the alarm.

[0009] Furthermore, preferably, both the flow meter and the solenoid valve are electrically connected to the controller.

[0010] Furthermore, preferably, the end of the waste liquid ditch is connected to the tailings pipe, and the underflow filtrate pipe of the vibrating screen is also connected to the tailings pipe.

[0011] Furthermore, preferably, the aperture of the separating screen is the same as that of the vibrating screen.

[0012] The beneficial effects of this utility model are as follows: By applying the synergistic operation of a vibrating screen and a separation net in the collection tank, this utility model achieves efficient separation of gold and silver-loaded carbon slurry, ensuring the recovery efficiency of precious metals such as gold and silver; at the same time, the intelligent monitoring system and alarm function equipped with this device can monitor the carbon slurry flow in real time and provide timely warnings in case of abnormalities. Combined with an automatic flushing device, it effectively prevents the separation net from clogging, maintains stable filtration efficiency, and reduces resource loss and equipment failure risks; in addition, the optimized tailings discharge design reduces the risk of environmental accidents, alleviates the burden of manual maintenance, and ensures the continuity and stability of the production process.

[0018] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0019] like Figure 1 Figure 2 As shown, a gold-silver-loaded char separation and recovery device mainly consists of a feed pipe 1, a vibrating screen 2, a collection tank 4, a separation screen 5, a waste liquid ditch 6, a tailings pipe 7, a flushing water pipe 8, a solenoid valve 9, a flow meter 3, a controller 10, and an alarm 11. The feed pipe 1 is located above the vibrating screen 2 and is responsible for conveying the gold-silver-loaded char slurry to the vibrating screen 2. A collection tank 4 is located on one side of the vibrating screen 2, and the discharge port of the vibrating screen 2 is directly opposite the open top of the collection tank 4 to ensure accurate material delivery. A separation screen 5 is connected to the upper inner wall of the collection tank 4, and the mesh size of the separation screen 5 is the same as that of the vibrating screen 2 to maintain a uniform screening standard. A discharge port connected to the waste liquid ditch 6 is located on one side of the bottom of the collection tank 4. The end of the waste liquid ditch 6 is connected to the tailings pipe 7, and the underflow filter pipe of the vibrating screen 2 is also connected to the tailings pipe 7, forming a complete liquid discharge path.

[0020] In addition, a flushing water pipe 8 is connected to one side of the collection tank 4. The flushing water pipe 8 is positioned higher than the separation net 5, and a solenoid valve 9 is installed on the flushing water pipe 8. A flow meter 3 is installed on the feed pipe 1. Both the flow meter 3 and the solenoid valve 9 are electrically connected to the controller 10, which is electrically connected to the alarm 11, enabling real-time monitoring and feedback of the flow rate of the gold and silver charcoal slurry and timely alarm notification of abnormal flow. This also facilitates the opening and closing control of the solenoid valve 9.

[0021] Working principle: When the gold and silver-loaded carbon slurry flows into the vibrating screen 2 in large quantities through the feed pipe 1, it continues to flow along the screen to the separation screen 5 above the collection tank 4. During this process, solid-liquid separation occurs. The gold and silver-loaded carbon is trapped by the separation screen 5, while the filtrate falls to the lower part of the collection tank 4, and is discharged to a designated location through the outlet, waste ditch 6, and finally through the tailings pipe 7. During system operation, if the flow meter 3 detects that the feed flow rate exceeds the set value, the controller 10 immediately triggers the alarm 11 to sound an alarm, and at the same time opens the solenoid valve 9 and starts the flushing water pipe 8 to flush the separation screen 5, thereby improving filtration efficiency, preventing carbon slurry overflow and clogging of the separation screen 5, and ensuring efficient recovery of solid particles.

[0022] The present invention has been described in detail above through specific and preferred embodiments. However, those skilled in the art should understand that the present invention is not limited to the embodiments described above. Any modifications or equivalent substitutions made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
