Description

Technical Field

[0001] This utility model relates to the field of mine water supply technology, specifically to an automated water supply control system suitable for open-pit mine beneficiation plants. Background Technology

[0002] Ore processing plants are typically located far from urban areas, built against mountainsides, without large reservoirs or water sources nearby. However, the ore processing process requires a large amount of clean water. Many ore processing plants rely primarily on surface overflows and water seepage from the mining pits for their water supply. With multiple water sources, and the increasing volume of ore processed annually, water demand is rising sharply. The contradiction between water scarcity and increasing water consumption is becoming increasingly prominent, and water transportation costs are skyrocketing. Effective control through manual labor and simple electric valves is insufficient, leading to water waste. Although a Chinese invention patent, "A Water Collection and Supply System and Method for Mine Waste Dumps" (Publication No. CN110741), exists, the problem persists. 910A) describes a structure including a water collection tank, which includes a water-resistant wall located below the surface of the spoil heap, forming a closed tank body. The tank body is equipped with an inlet and an outlet, and the inside of the water collection tank is lined with a waterproof layer; a water collection structure located at the top of the spoil heap and connected to the inlet of the water collection tank, which is used to collect rainwater from the top of the spoil heap and channel it into the water collection tank; an outlet pipe passing through the outlet of the water collection tank and connecting the inside and outside of the water collection tank, with a drive mechanism connected to the outlet pipe for discharging water; and an irrigation device connected to the outlet of the outlet pipe. This structure is suitable for water supply to spoil heaps, but not for mineral processing plants. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an automated water supply control system suitable for open-pit mine concentrators.

[0004] The specific technical solution of this utility model is: an automated water supply and control system suitable for open-pit mine beneficiation plants, including a high-level water storage tank, water inlet points, and open-pit mine pit water supply points. There are two or more high-level water storage tanks and two or more water inlet points. A water inlet flow valve group is installed between the water inlet points, the open-pit mine pit water supply points, and the high-level water storage tanks. A water inlet discharge electric valve is installed between the water inlet points and the water inlet flow valve group. A water point flow meter and an electric valve are installed at each water point supplied by the high-level water storage tank. A water level gauge is installed in the high-level water storage tank.

[0005] Furthermore, preferably, the water supply point in the open-pit mine is equipped with a water pump.

[0006] Furthermore, preferably, a high-level water storage tank inlet flow valve group is provided between the inlet water flow valve group and the high-level water storage tank.

[0007] Furthermore, preferably, the elevated water storage tank includes an elevated production water storage tank and an elevated domestic water storage tank.

[0008] Furthermore, preferably, the elevated water storage tank includes an elevated production water storage tank I, an elevated production water storage tank II, an elevated domestic water storage tank I, and an elevated domestic water storage tank II.

[0009] Furthermore, preferably, the water inlet points include water inlet point I and water inlet point II. Water inlet point I supplies water to high-level production water storage tank I and high-level domestic water storage tank I respectively through pipelines. Water inlet point I is equipped with water flow valve group I. Water inlet point II supplies water to high-level production water storage tank I, high-level production water storage tank II and high-level production water storage tank II respectively through pipelines. Water inlet point II is equipped with water flow valve group II. The open-pit mine water supply point supplies water to high-level production water storage tank II and high-level production water storage tank II respectively through pipelines. Water inlet mine water supply point is equipped with water flow valve group III.

[0010] Furthermore, preferably, an electric valve I for draining incoming water is installed between water inlet point I and water flow valve group I, and an electric valve II for draining incoming water is installed between water inlet point II and water flow valve group II.

[0011] The beneficial effects of this invention are as follows: By installing level sensors in elevated water storage tanks (two or more tanks) to detect the liquid level, and installing flow meters and electric valves at the inlet and outlet of the elevated water storage tanks, as well as at each water source point, intelligent water supply regulation is achieved by judging the flow rate at each water point, the inlet flow rate, and the water level in the tanks. This avoids water waste caused by overflowing when the elevated water storage tanks are full, and allows for rapid water supply regulation when water consumption at each water point increases sharply. This enables intelligent regulation of production and domestic water use in mineral processing plants, improving water resource utilization and reducing costs. Attached Figure Description

Detailed Implementation

[0014] To make the technical problems and solutions solved by this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0015] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:

[0017] like Figures 1 to 3 As shown, an automated water supply control system suitable for open-pit mine concentrators includes an elevated water storage tank 1, a water inlet point 2, and an open-pit mine water supply point 9. In this embodiment, four elevated water storage tanks 1 are set up, which are divided into elevated production water storage tanks I101 and II102 for supplying water to the production equipment of the concentrator, and elevated domestic water storage tanks I103 and II104 for supplying domestic water to the concentrator. Separating production and domestic water storage is to prioritize the operation of equipment and prevent equipment shutdown or equipment damage due to lack of water.

[0018] Water inlet 2 consists of two points: water inlet Ⅰ201 and water inlet Ⅱ202. Each water inlet 2 supplies water to two or more high-level reservoirs 1. Specifically, water inlet Ⅰ201 supplies water to high-level production reservoir Ⅰ101 and high-level domestic reservoir Ⅰ103 via pipelines, while water inlet Ⅱ202 supplies water to high-level production reservoir Ⅰ101, high-level production reservoir Ⅱ102, and high-level production reservoir Ⅱ104 via pipelines. Of course, the number of water inlet 2 points can be set according to the specific number of mines, and the water supply situation of water inlet 2 to high-level reservoirs 1 can also be set by technicians according to the situation. It can be that one water inlet 2 supplies water to multiple high-level reservoirs 1, or one water inlet 2 supplies water to one high-level reservoir 1, all of which are within the technical protection scope of this utility model.

[0019] Water pump 8 is installed at the open-pit mine water supply point 9. Water supply point 9 supplies water to high-level production water storage tank II 102 and high-level production water storage tank II 104 through pipelines.

[0020] Furthermore, a water flow valve assembly I301 is installed on the main pipeline of water inlet I201. That is, a water flow valve assembly I301 is installed on the main pipeline section of the water supply pipe of water inlet I201. The water flow valve assembly I301 refers to the total flow meter I and electric valve I of the water inlet. The water flow valve assembly I301 is used to count the water supply of water inlet I201 and to control whether the valve of water inlet I201 opens or closes to supply water to the high-level production water storage tank I101 and the high-level domestic water storage tank I103.

[0021] The flow valve group in this utility model technical solution includes a flow meter and an electric valve. Because they are set and used in pairs, for ease of identification and explanation, the flow valve group is used for description. That is, the inlet water flow valve group includes an inlet water flow meter and an electric valve, the high-level water storage tank inlet flow valve group includes a high-level water storage tank inlet flow meter and an electric valve, and the water point flow valve group includes a water point flow meter and an electric valve.

[0022] On the branch pipe connecting water inlet I201 and high-level production water storage tank I101, there is a high-level water storage tank inlet flow valve group I401. On the branch pipe connecting water inlet I201 and high-level domestic water storage tank I103, there is a high-level water storage tank inlet flow valve group II402. Similarly, they are used to count the specific flow rate of water from water inlet I201 into high-level production water storage tank I101 and high-level domestic water storage tank I103, and to precisely control the inlet valves to ensure that the water volume of each water storage tank is balanced and the system operates efficiently and stably.

[0023] A water inlet flow valve group II302 is also installed on the main pipeline of water inlet II202. A high-level water storage tank inlet flow valve group III403 is installed on the branch pipeline connecting water inlet II202 and high-level production water storage tank I101. A high-level water storage tank inlet flow valve group IV404 is installed on the branch pipeline connecting water inlet II202 and high-level production water storage tank II102. A high-level water storage tank inlet flow valve group V405 is installed on the branch pipeline connecting water inlet II202 and high-level domestic water storage tank II104. Their functions are the same as the aforementioned valve groups, ensuring precise control of water volume in each water storage tank and making the system operation more efficient and stable.

[0024] The main pipeline of the open-pit mine water supply point 9 is equipped with an inlet flow valve group Ⅲ303. The branch pipeline connecting the open-pit mine water supply point 9 to the high-level production water storage tank Ⅱ102 is equipped with a high-level water storage tank inlet flow valve group Ⅵ406. The branch pipeline connecting the open-pit mine water supply point 9 to the high-level domestic water storage tank Ⅱ104 is equipped with a high-level water storage tank inlet flow valve group Ⅶ407. Their functions are the same as the aforementioned valve groups, accurately counting and regulating the water volume to ensure the stable and efficient operation of the water supply system.

[0025] High-level production water storage tank I101, high-level production water storage tank II102, high-level domestic water storage tank I103, and high-level domestic water storage tank II104 are respectively equipped with water level gauges I701, II702, III703, and IV704 to monitor the changes in the water level of each water storage tank in real time. The data is fed back to the central control system, which automatically adjusts the flow valve group to ensure a constant water level and accurate operation of the water supply system.

[0026] An electric inlet water discharge valve I601 is installed between water inlet point I201 and water flow valve group I301, and an electric inlet water discharge valve II602 is installed between water inlet point II202 and water flow valve group II302. Electric inlet water discharge valves I601 and II602 are used to discharge excess water to a designated area when the inflow exceeds the outflow.

[0027] Each of the following systems is equipped with a flow valve group I501 for water supply to various water-using equipment in the ore dressing plant: high-level production water storage tank I101; high-level production water storage tank II102; high-level domestic water storage tank I103; and high-level domestic water storage tank II104. Each of these valve groups is used to count water consumption and control the opening and closing of water supply to equipment.

[0028] And several collectors 10 are set up, such as Figure 4 As shown, in open-pit mines, due to the long distances between water supply points, flow meters and electric regulating valves are installed on each water supply pipeline and at each external drainage and water usage point. Level gauges are installed in high-level water storage tanks. Data acquisition units 10 are installed at the convergence points of each flow meter and electric valve. Communication is constructed through an Internet of Things (IoT) consisting of frequency converters, PLC controllers, data transmitters, and other equipment in the acquisition unit 10. The acquisition units communicate with each other on the same network segment and upload data to the IoT. Data can be obtained and electric valves can be controlled via computers and mobile apps. IoT control and transmission technologies are already mature technologies. In this embodiment, they are mainly used for the control of electric valves and water pumps, as well as the transmission of data from flow meters and level gauges.

[0029] When the system is working, it collects data through each collector 10 and communicates with each other. When it is determined that the liquid level of a certain pool is too high or too low, it adjusts the water supply according to the water flow valve group 3 of each pipeline. For example, if the liquid level of the high-level production water storage pool I101 (production) is too low, the electric valve I601 and the electric valve II602 for water discharge are closed. Depending on the situation, the inlet flow valve group of the high-level domestic water storage pool can be further closed. If the pool liquid level recovers, the external drainage valve and the inlet valve of the high-level domestic water storage pool are reopened to ensure the supply of production water and to prevent water from flowing into the water storage pool and overflowing into the mining area and causing pollution.

[0030] This technology can reduce water waste by installing level sensors in elevated water storage tanks (two or more tanks) to detect water levels, and installing flow meters and electric valves at the inlet and outlet valves of the elevated water storage tanks, as well as at each water source point. By judging the flow rate at each water point, the flow rate at the water source point, and the water level in the tank, intelligent water supply regulation can be achieved, avoiding water waste caused by overflow when the elevated water storage tank is full, and quickly regulating water use when water consumption at each water point increases sharply. Example 2:

[0031] like Figure 5 As shown, this implementation differs from the first implementation in that it also includes a water inlet point Ⅲ203. Water inlet point Ⅲ203 supplies water to the high-level production water storage tank Ⅰ101 separately. In this case, only one water flow valve group Ⅳ304 needs to be installed, because the water from water inlet point Ⅲ203 enters the high-level production water storage tank Ⅰ101 and does not enter other water storage tanks. Of course, a water discharge electric valve Ⅲ603 needs to be installed between water inlet point Ⅲ203 and water flow valve group Ⅳ304.

[0032] 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.
