Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, specifically to an automatic activated carbon discharging device for gold mines. Background Technology

[0002] Heap leaching-activated carbon static adsorption is a common production process in gold mines. In the precious liquor adsorption section, adsorption columns containing activated carbon are generally used to treat gold-bearing precious liquor, adsorbing gold complexes in the liquor. The activated carbon can be acid-washed and reactivated during production and then returned to the adsorption column for reuse. Carbon release is typically achieved by utilizing terrain elevation differences, using carbon release pipes and control valves.

[0003] However, manual carbon release is inefficient, requires workers to open and close a large number of control valves, and is prone to operational errors due to workers' subjective factors. At the same time, it also increases the labor costs of mining enterprises and is not conducive to improving management level. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention discloses an automatic activated carbon discharge device for gold mines, which replaces manual labor with automated control methods to achieve one-button automatic carbon discharge operation.

[0005] To achieve the above objectives, the technical solution of this invention is as follows:

The water supply pipe is located above the carbon storage tank, and a carbon discharge port is located at the lower end of the carbon storage tank. A drainage pipe is located at the bottom of the carbon storage tank on one side of the carbon discharge port. The carbon discharge port is connected to the carbon discharge pipe, which is connected to the top of the adsorption column via a branch pipe. An underwater ranging sensor for detecting the height of the carbon layer inside the adsorption column is also located at the top of the inner wall of the adsorption column. The water supply pipe is equipped with an electric control valve one, the drainage pipe with an electric control valve two, the carbon discharge port with an electric control valve three, the branch pipe with an electric control valve four, and the carbon discharge pipe on the side of the branch pipe away from the carbon discharge port with an electric control valve five. The control system is electrically connected to a power module and is electrically connected to electric control valves one, two, three, four, and five, and the underwater ranging sensor via wires.

[0008] Preferably, the carbon discharge pipe is further connected to a branch pipe, and the branch pipe is equipped with an electric control valve.

[0009] Preferably, the branch pipe is a U-shaped pipe, with one electrically controlled valve spanning both ends of the U-shaped pipe, and both ends of the U-shaped pipe are connected to the carbon discharge pipe.

[0010] Preferably, the control system further includes a timing module, and the control system is configured to control electric control valves three, four, five, and six through the timing module.

[0011] Preferably, the carbon storage tank is equipped with a liquid level sensor, which is electrically connected to the control system via a wire.

[0012] Preferably, the liquid level sensor includes a liquid level detection tube disposed on one side of the carbon storage tank, the bottom of the liquid level detection tube being connected to the bottom of the carbon storage tank via a connecting pipe, the liquid level detection tube containing a liquid level sensor body, and the starting end of the connecting pipe being provided with a metal filter screen.

[0013] Preferably, the liquid level sensor body includes a ball scale disposed longitudinally on the inner wall surface of the detection tube, the reading head of the ball scale is connected to a buoyancy block, and the ball scale is electrically connected to the control system via a wire.

Detailed Implementation

[0020] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0021] Example 1

[0022] An automatic activated carbon discharge device for gold mines, such as Figure 1 As shown, the system includes a control system, a water supply pipe 1, a carbon storage tank 2, a drainage pipe 3, a carbon discharge pipe 5, an adsorption column 7, and an underwater ranging sensor 9. The water supply pipe 1 is located above the carbon storage tank 2 and provides water flow power for the carbon discharge operation. The carbon storage tank 2 is used for temporary storage of spare activated carbon, and the carbon discharge operation is carried out based on the carbon layer height measured by the underwater ranging sensor. The drainage pipe 3 is located at the bottom of the carbon storage tank 2 and is used to drain excess water from the carbon storage tank 2 after the carbon discharge operation is completed. The electric control valve 4 is used as the main control valve for the carbon discharge operation and is located on the carbon discharge port of the carbon storage tank. The carbon discharge pipe 5 is connected to the discharge... The carbon outlet connection serves as the main conveying pipeline for activated carbon discharge operations. The electrically controlled valve 6 is located on a branch pipe of the discharge pipeline and is used to control the target position of the activated carbon discharge operation, interlocked with the underwater distance sensor 9. An electrically controlled valve 8 is located on the discharge pipeline 5 on the side of the branch pipe furthest from the carbon outlet, controlling the target position of the discharge operation and interlocked with the underwater distance sensor 9. The underwater distance sensor 9 is used to measure the carbon layer height within the adsorption column 7 and is located at the top of the inner wall of the adsorption column. The discharge operation is based on the amount of carbon added according to the required height of the carbon layer within the adsorption column, serving as the primary control basis for the discharge operation. Simultaneously, the water supply pipeline is equipped with an electrically controlled valve, and the drainage pipeline is equipped with an electrically controlled valve, facilitating fully automated control of the entire process.

[0023] Example 2

[0024] like Figure 1 As shown:

[0025] The water supply pipe 1 is made of φ50 ordinary welded pipe, and there is an electric control valve at the top to control the addition of industrial water. It is used to add industrial water to the carbon storage tank 2 to facilitate the transportation of activated carbon.

[0026] The carbon storage tank 2 is a square tank made of 8mm steel plate welded together, with a funnel-shaped four-sided pyramid bottom to facilitate the centralized discharge of activated carbon.

[0027] The drainage pipe 3 is a DN100 ordinary welded pipe, located at the bottom of the carbon storage tank 2, penetrating the tank wall of the carbon storage tank 2. The area inside the carbon storage tank 2 needs to be perforated and fitted with a stainless steel screen. The part outside the carbon storage tank 2 is equipped with an electric drain valve 2, which is used to drain excess water during carbon storage.

[0028] The aforementioned electric control valve 4 is a DN100 electric gate valve located at the carbon discharge port of the carbon storage tank 2, used to control the start and stop of the carbon discharge operation. It is electrically interlocked with the water supply pipe 1 and the drainage pipe 3.

[0029] The carbon discharge pipe 5 is a DN100 ordinary welded pipe, used to transport carbon from the carbon storage tank 2 to the target area.

[0030] The electric control valve 6 is located on the branch pipe of the carbon discharge pipeline and is used to control the flow direction of carbon in the carbon discharge pipeline. It is electrically interlocked with the underwater ranging sensor 9.

[0031] The electric control valve 8 is located on the carbon discharge pipe 5 and is used to control the flow direction of carbon in the carbon discharge pipe. It is electrically interlocked with the underwater ranging sensor 9.

[0032] The underwater ranging sensor 9 is an inductive ranging element used to measure the height of the underwater carbon layer inside the adsorption column 7, determine the target area for releasing carbon from the carbon storage tank, and is electrically interlocked with the electric control valve 6 and the electric control valve 8 to achieve precise carbon release.

[0033] The principle of the above embodiments of this novel invention is as follows: During use, when the activated carbon in the adsorption column 7 decreases due to carbon transfer operations, the underwater ranging sensor 9 senses that the carbon layer height is lower than the target set value. At this time, the electric control valve 1 and electric control valve 3 4 on the water supply pipe 1 will be activated simultaneously to start the carbon discharge operation. The activated carbon temporarily stored in the carbon storage tank 2 will be added to the target adsorption column 7. During this period, the electric control valve 4 6 and the adjacent electric control valve 5 8 will be interlocked to accurately clear the carbon discharge pipe 5 through water flow, ensuring that the activated carbon in the carbon storage tank 2 is accurately delivered to the adsorption column 7 that needs to be replenished as measured by the underwater ranging sensor 9. After the carbon layer height reaches the target height, the underwater ranging sensor 9 transmits data, and the control system closes the electric control valve 1 and electric control valve 3 4, closes the electric control valve 4 6 and the adjacent electric control valve 5 8, and opens the electric control valve 2 of the drainage pipe 3 to drain the excess water in the carbon storage tank 2, thus ending the carbon discharge operation.

[0034] Previously, the activated carbon discharge operation involved numerous control valves, with the water supply valve located far from each other and not on the same plane, making manual control cumbersome. Furthermore, the discharge process was lengthy, requiring continuous on-site carbon layer measurement to ensure accurate carbon layer height as required by the process. This device optimizes the control method. Relying on the underwater distance sensor 9 to measure the carbon layer height within the adsorption column, it automatically initiates the discharge operation. It interlocks with the electric control valves 1, 3, 4, 4, and 5 on the water supply pipeline 1, accurately discharging the activated carbon pre-stored in the carbon storage tank 2 to the target adsorption column. The discharge operation is accurate and efficient, requiring no manual supervision or operation, saving both labor and production time.

[0035] Example 3

[0036] Based on the above embodiments, this embodiment further discloses:

[0037] like Figure 2 As shown, the carbon discharge pipe 5 is also connected to a branch pipe, and the branch pipe is equipped with an electric control valve 611.

[0038] like Figure 2 As shown, the branch pipe is a U-shaped pipe 10, with an electric control valve 8 spanning both ends of the U-shaped pipe 10, and both ends of the U-shaped pipe are connected to the carbon discharge pipe 5.

[0039] like Figure 2 As shown, the control system is further equipped with a timing module, and the control system is configured to control electric control valve 4, electric control valve 6, electric control valve 8, and electric control valve 11 through the timing module.

[0040] In this embodiment, considering that a large amount of activated carbon needs time to settle after entering the adsorption column 7, the real-time value detected by the underwater ranging sensor 9 may not match the true value, and there is a possibility that the collected data represents the height of the activated carbon surface during the settling process. Therefore, this embodiment is equipped with a timing module and branch pipes. In use, when a certain adsorption column 7 needs to be replenished with activated carbon, activated carbon is first replenished as described in Embodiments 1 and 2. When the underwater ranging sensor 9 detects that the activated carbon surface height has reached the standard value, the replenishment of activated carbon is stopped, the timing module is activated, and after a certain period of time, the height data of the activated carbon surface is collected again by the underwater ranging sensor 9. If there is an error with the standard value, activated carbon is further replenished. After reaching the standard height, the replenishment is stopped again. This cycle is repeated until the activated carbon surface height detected by the underwater ranging sensor 9 reaches a stable value and is consistent with the standard value.

[0041] If multiple adsorption columns require replenishment of activated carbon, after closing the electric control valve 6 of one adsorption column and the adjacent electric control valve 8, the activated carbon in another adsorption column can be replenished by opening the electric control valve 11, connecting one or more U-tubes 10, and opening the electric control valve 6 of the corresponding adsorption column (closing its adjacent electric control valve 8). This process of alternating replenishment and collecting data after activated carbon sedimentation can ultimately replenish the activated carbon in multiple adsorption columns to the standard value.

[0042] Example 4

[0043] Based on Example 1, this example further discloses:

[0044] like Figure 3As shown, the carbon storage tank 2 is equipped with a liquid level sensor, which is electrically connected to the control system via a wire.

[0045] like Figure 3 As shown, the liquid level sensor includes a liquid level detection tube 12 located on one side of the carbon storage tank. The bottom of the liquid level detection tube 12 is connected to the bottom of the carbon storage tank 2 through a connecting tube 16. The liquid level detection tube 12 contains a liquid level sensor body, and the starting end of the connecting tube 16 is provided with a metal filter screen.

[0046] like Figure 3 As shown, the liquid level sensor body includes a ball grid ruler 13 arranged longitudinally on the inner wall surface of the detection tube 12. The reading head 14 of the ball grid ruler 13 is connected to a buoyancy block 15. The ball grid ruler 13 is electrically connected to the control system through a wire.

[0047] In this embodiment, to improve the speed of activated carbon replenishment, a further usage method is provided. Specifically, before replenishing activated carbon, a measured amount of industrial water is injected into the carbon storage tank. A level sensor detects the liquid level. When activated carbon needs to be replenished, the corresponding electric control valve 3 (4) is opened and the corresponding electric control valve 5 (8) is closed. The corresponding electric control valve 4 (6) is then opened. Due to the water pressure, the activated carbon can quickly flow into the designated adsorption column. When the liquid level is lower than the set value, electric control valve 1 can be opened to replenish water to the carbon storage tank. Similarly, after replenishing activated carbon, when draining water by opening electric control valve 2, electric control valve 2 can be closed promptly based on the level sensor's detection. It should be noted that when multiple adsorption columns need to be replenished with activated carbon, ensuring a sufficient water supply and relatively constant water pressure can improve working efficiency and achieve better automatic control.
