Description

Technical Field

[0001] The utility model relates to the technical field of slurry sampling, and particularly relates to a carbon density sampling device for a carbon-in-leach system. Background Art

[0002] The carbon-in-pulp process for extracting gold and silver uses activated carbon to adsorb gold and silver in the pulp. During this process, the density of the activated carbon has an important influence on the adsorption of gold and silver. Therefore, during the cyanidation leaching and adsorption process, it is necessary to regularly sample and measure the density of the activated carbon in the carbon-in-leach tank. However, how to collect representative samples becomes particularly important, and the rationality of the sampling equipment is one of the key factors affecting the representativeness of the samples. Traditional activated carbon sampling uses a sampling kettle for manual sampling. The structure is simple and easy to manufacture, but it is mostly applicable to open and easily intercepted slurry sampling. For the sampling of slurry in a carbon-in-leach tank with a high depth, using a kettle for sampling requires frequent operations, resulting in a large labor intensity. Moreover, due to the structure of the kettle and human factors, the representativeness of the samples obtained is poor, leading to a large measurement error in carbon density and unable to accurately reflect the actual situation of the activated carbon density.

[0003] Therefore, it is necessary to develop a sampling device that can ensure the representativeness of the collected samples and provide reliable carbon density data. Summary of the Utility Model

[0004] The utility model provides a carbon density sampling device for a carbon-in-leach system.

The discharge port of the vacuum diaphragm pump is connected to a sampling bucket through a pipeline. The inlet port of the vacuum diaphragm pump is communicated with a sampling steel wire hose. The other end of the sampling steel wire hose is wound around the drum of an electric hoisting mechanism and then slidably connected to a pulley support mechanism, and is communicated with a heavy-duty traction sampler. One end of the drum is connected to the output shaft of a speed reducer. The input shaft of the speed reducer is connected to the output shaft of a motor through a coupling. The motor is electrically connected to a control cabinet. The electric hoisting mechanism and the pulley support mechanism drive the heavy-duty traction sampler to lift and lower in the carbon-in-leach tank.

[0006] Further, preferably, it further includes a flushing mechanism. The flushing mechanism includes a centrifugal pump. The inlet port of the centrifugal pump is connected to a clear water pipe.

[0007] Further, preferably, a sampling guide pipe is sleeved outside the heavy-duty traction sampler. The sampling guide pipe is vertically installed in the carbon-in-leach tank, and there are openings on the sampling guide pipe for the slurry to enter.

[0017] As Figure 1 shown, a carbon density sampling device for a carbon-infiltration system includes a vacuum diaphragm pump 10. The outlet of the vacuum diaphragm pump 10 is connected to a sampling bucket 11 through a pipeline. The inlet of the vacuum diaphragm pump 10 is communicated with a sampling steel wire hose 5. The other end of the sampling steel wire hose 5 is wound around the drum 701 of an electric winch mechanism and then slidably connected to a pulley support mechanism 6, and is communicated with a heavy-duty traction sampler 4. One end of the drum 701 is connected to the output shaft of a speed reducer 702. The input shaft of the speed reducer 702 is connected to the output shaft of a motor 703 through a coupling. The motor 703 is electrically connected to a control cabinet 704. The electric winch mechanism and the pulley support mechanism 6 drive the heavy-duty traction sampler 4 to lift and lower in a carbon-infiltration tank 1. During sampling, the start, stop, rotation speed, and rotation direction of the motor are controlled through the control cabinet 704, and then the rotational force of the motor 703 is converted into the moving force of the drum 701 by the speed reducer 702 and the drum 701, so as to control the lifting and lowering of the heavy-duty traction sampler 4 in the carbon-infiltration tank, enabling the heavy-duty traction sampler 4 to reach any sampling point.

[0018] The above sampling device further includes a flushing mechanism. The flushing mechanism includes a centrifugal pump 801. The inlet of the centrifugal pump 801 is connected to a clear water pipe 802. The outlet of the centrifugal pump 801 is connected to a flushing water pipe 803. The other end of the flushing water pipe 803 is connected to the sampling steel wire hose 5 between the vacuum diaphragm pump 10 and the drum 701. Valves 901, 902, and 903 are installed at the connection position of the flushing water pipe 803 and the sampling steel wire hose 5.

[0019] A sampling guide pipe 3 is sleeved outside the above-mentioned heavy-duty traction sampler 4. The sampling guide pipe 3 is vertically installed in the carbon-infiltration tank 1 and is far from the stirring device 2. There is an opening on the sampling guide pipe 3 for the slurry to enter. In this application, the sampling guide pipe 3 is provided to guide the heavy-duty traction sampler 4, enabling the heavy-duty traction sampler 4 to perform a lifting and lowering movement in the sampling guide pipe 3, avoiding the disturbance of the stirring of the stirring device 2 to the heavy-duty traction sampler 4, and ensuring smooth sampling. As Figure 3 shown, to ensure the uniformity of the slurry in the sampling guide pipe 3, the sampling guide pipe 3 is formed by connecting at least three longitudinal rods and at least three rings. The longitudinal rods and the rings are steel bars, and two rings are welded between the three longitudinal rods.

[0020] AsFigure 2 As shown, the heavy-duty traction sampler 4 and the sampling steel wire hose 5 are connected by a flange. The bottom of the heavy-duty traction sampler 4 is spherical, making the extracted slurry more uniform and improving the representativeness of the sample.

[0021] Working principle: During sampling, set the sampling interval time and specific sampling position through the human-machine interaction interface of the control cabinet 704, start the electric hoisting mechanism to release the sampling steel wire hose 5, and the heavy-duty traction sampler 4 descends along the sampling guide pipe 3 under its own weight. When reaching the set sampling position, the electric hoisting mechanism stops working, open Valve 1 and Valve 2, start the vacuum diaphragm pump 10, extract the slurry at the sampling position into the sampling bucket 11. After the slurry flowing out of the sampling pipe is stable, then use a sampling pot to collect the required sample to complete the sampling operation.

[0022] After sampling is completed, close Valve 1, start the centrifugal pump 801. The centrifugal pump 801 extracts clear water to flush the sampling pipe from the flushing water pipe 803 to the sampling bucket 10 section and the vacuum diaphragm pump 10; then stop the vacuum diaphragm pump 10, close Valve 2, and the centrifugal pump 801 extracts clear water to flush the sampling steel wire hose 5 from the flushing water pipe 803 to the heavy-duty traction sampler 4 section. After the flushing is completed, stop the centrifugal pump 801, thus completing the flushing of the entire sampling device and avoiding contamination during the next sampling.

[0023] The above has described the present invention in detail through specific and preferred embodiments. However, those skilled in the art should understand that the present invention is not limited to the above-described embodiments. Any modifications, equivalent replacements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
