Description

Technical Field

[0001] The utility model relates to the technical field of mining production, in particular to a system for recycling mine water inflow. Background Art

[0002] During the construction and production of a mine, atmospheric precipitation, surface water (rivers, lakes, seas, reservoirs, etc.) and groundwater may all flow into the mine through various channels. The water flowing into the mine is collectively referred to as mine water inflow. The amount and inflow state of mine water inflow directly affect the construction and production of the mine. Usually, mine water inflow continuously and slowly flows into the mine and is drained to the ground through underground drainage equipment. Especially during the rainy season, the amount of water inflow is even greater. However, this water resource is often wasted and not effectively utilized.

[0003] Currently, many ore dressing plants have started to use mine water inflow. Generally, there are two sources of water entering the storage water tank of the ore dressing plant. One is mine water inflow, which flows into the storage water tank of the ore dressing plant by gravity through a pipeline. The other is fresh water, which is supplemented from the new water tank in the plant area to the storage water tank of the ore dressing plant through a pipeline. Therefore, the problem of how to effectively use mine water inflow as fresh water for the production of the ore dressing plant and reduce the water intake from the water source has become an urgent problem to be solved. In addition, due to the special requirements of safety production and water supply quality, there are strict requirements for the constant pressure water supply pressure. Content of the Utility Model

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a system for recycling mine water inflow.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A system for recycling mine water inflow includes a first storage water tank. The upper part of the first storage water tank is connected to the underground water inflow and the fresh water pipeline through a pipeline. The first storage water tank is connected to a second storage water tank through a connecting pipe. The water outlet ends of the first storage water tank and the second storage water tank are both connected to a variable frequency constant pressure pumping station through a pipeline. The water coming out of the variable frequency constant pressure pumping station is connected to the new water pipeline network of the ore dressing plant.

[0007] Furthermore, an electric valve is arranged on the underground water inflow and the fresh water pipeline connected to the upper part of the first storage water tank.

[0008] Furthermore, electric valves are arranged at the water outlet ends of the first storage water tank and the second storage water tank.

[0009] Furthermore, a water level sensor is arranged in the first storage water tank. When the amount of mine water inflow is insufficient and the water level in the first storage water tank drops to a certain level, the electric valve of the fresh water pipeline automatically opens to supplement the shortage of mine water inflow. When the amount of mine water inflow increases to a certain level, the fresh water electric valve automatically closes, and mine water inflow is preferentially used.

[0010] Furthermore, the number of the variable-frequency constant-pressure pumping stations is two groups, one for use and one for standby.

[0011] Furthermore, the variable-frequency constant-pressure pumping station is composed of a 90kw horizontal multi-stage pump and a variable-frequency control cabinet.

[0012] The utility model has the following beneficial effects:

[0013] The utility model utilizes the underground water inflow in the mine as the new water for the production of the beneficiation and smelting plant, reducing the water intake from the water source. Through the water level control signal, the mine water inflow is preferentially used to enter the water storage tank. When the mine water inflow is insufficient and the water level in the water storage tank drops to a certain level, the electric valve of the new water pipeline automatically opens to supplement the shortage of the mine water inflow. When the mine water inflow increases to a certain level, the new water electric valve automatically closes, and the mine water inflow is preferentially used. In addition, by setting up a variable-frequency constant-pressure pumping station, the special needs of the safe production and water supply quality of the beneficiation and smelting plant are met. The constant-pressure water supply method has a constant water pressure, is convenient to operate, runs reliably, saves electric energy, and has a high degree of automation.

It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0018] Referring to Figure 1 As shown, in a preferred embodiment of the utility model, a mine water inflow recovery and reuse system includes a first water storage tank 1. The upper part of the first water storage tank 1 is connected to the underground water inflow pipeline 4 and the new water pipeline 8 through pipelines. The first water storage tank 1 is connected to the second water storage tank 2 through a connecting pipe 3. The water outlet ends of the first water storage tank 1 and the second water storage tank 2 are both connected to the variable-frequency constant-pressure pumping station 6 through pipelines, and the water outlet end of the variable-frequency constant-pressure pumping station 6 is connected to the new water pipe network 7 of the beneficiation and smelting plant.

[0019] In this embodiment, an electric valve 5 is provided on the underground water inflow and new water pipelines connected to the upper part of the first water storage tank 1.

[0020] In this embodiment, electric valves are provided at the water outlet ends of the first water storage tank 1 and the second water storage tank 2.

[0021] In this embodiment, a water level sensor is provided inside the first water storage tank 1. When the mine water inflow is insufficient and the water level in the first water storage tank drops to a certain level, the electric valve of the fresh water pipeline automatically opens to make up for the shortage of mine water inflow. When the mine water inflow increases to a certain level, the fresh water electric valve automatically closes, and the mine water inflow is preferentially used.

[0022] In this embodiment, the number of variable frequency constant pressure pumping stations 6 is two groups, one for use and one for standby.

[0023] In this embodiment, the variable frequency constant pressure pumping station 6 is composed of a 90kw horizontal multi-stage pump and a variable frequency control cabinet.

[0024] In this embodiment, a pressure gauge 9 is provided on the pipeline at the water outlet end of the variable frequency constant pressure pumping station.

[0025] Specific implementation process: The underground water inflow and the fresh water in the factory area are led to the two first water storage tanks and the second water storage tanks in the concentrator through pipelines for storage. Two 90kw horizontal multi-stage pumps and two variable frequency control cabinets are added, one for use and one for standby. The water level control signal of the PLC programmable controller is used to preferentially use the mine water inflow into the water storage tank. When the mine water inflow is insufficient and the water level in the water storage tank drops to a certain level, the electric valve of the fresh water pipeline automatically opens to make up for the shortage of mine water inflow. When the mine water inflow increases to a certain level, the fresh water electric valve automatically closes, and the mine water inflow is preferentially used. The underground mine water inflow is used as the fresh water for the production of the concentrator, reducing the water intake from the water source to achieve the purpose of saving fresh water. After the transformation, the concentrator will be supplied with water at a constant pressure by the internal variable frequency constant pressure pumping station.
