Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater recycling, and particularly relates to a cooling water recycling device for a mine exploitation crushing equipment. Background Art

[0002] In open-pit mine production, crushers have a large demand for cooling water. After multiple cone crushers cool the oil temperature through plate coolers, warm water higher than the ambient temperature is discharged. Given that the impact of this warm water on the water used for sprinkler and spray dust suppression is relatively small, this warm water can be reused after collection. The warm water converges and flows into a pre-prepared water tank to recover the warm water cooled by all crushers. However, due to insufficient pressure at the drainage outlet of the water tank or a long pipeline, the water pressure required for fog cannon dust suppression cannot be met, and thus the needs of large-mouth sprinkler and fog cannon dust suppression cannot be satisfied. Content of the Utility Model

[0003] To solve the problems raised in the above background art, the utility model provides a cooling water recycling device for a mine exploitation crushing equipment, which solves the problem that the water pressure required for fog cannon dust suppression cannot be met.

[0004] To achieve the above object, the utility model provides the following technical solution: A cooling water recycling device for a mine exploitation crushing equipment, including a water tank, a tank cover is movably installed on the top of the water tank, a water inlet pipe is movably installed on the surface of the tank cover, a drainage opening one is fixedly connected to the surface of the water tank, an overflow pipe is flange-connected to one side of the drainage opening one, a drainage opening two is fixedly connected to the surface of the water tank, a drain pipe one is flange-connected to one side of the drainage opening two, a tee joint is movably installed on the surface of the drain pipe one, a drain pipe two is movably installed inside the tee joint, a valve one is movably installed on the surface of the drain pipe one, a valve two is movably installed on the surface of the drain pipe two, one end of the drain pipe two is flange-connected to a constant pressure pump, a variable displacement mechanism is flange-connected to one side of the constant pressure pump, a pressure gauge is fixedly installed on the surface of the variable displacement mechanism, a control valve is fixedly installed inside the variable displacement mechanism, a control box is fixedly installed on the surface of the constant pressure pump, a drain pipe three is flange-connected to one side of the variable displacement mechanism, and a valve three is movably installed on the surface of the drain pipe three.

[0005] Preferably, the drainage opening one and the overflow pipe are located on the upper surface of the water tank.

[0006] Preferably, a pressure sensor is arranged inside the pipeline of the constant pressure pump.

[0007] Preferably, the inside of the control box includes a signal receiver, a signal processor and a controller.

[0008] Preferably, the number of the water inlet pipes is several.

[0009] Preferably, flanges are provided at the connection ends of the first drain port and the overflow pipe, the second drain port and the first drain pipe, the second drain pipe and the constant pressure pump, the constant pressure pump and the variable displacement mechanism, and the variable displacement mechanism and the third drain pipe.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] For the cooling water recovery device of the mine exploitation and crushing equipment, through the setting of the water inlet pipe, it is convenient for the warm water discharged by the crusher to enter the water tank and converge. The water in the water tank can be directly discharged through the second drain port and the first drain pipe. After the first valve is closed, the water can enter the second drain pipe through the three-way pipe for discharge. Through the setting of the constant pressure pump, it can detect the water pressure through the built-in pressure sensor. When the water pressure is lower than the set value, the pressure sensor transmits the signal to the control box, and then the controller built in the control box controls the control valve to open, thereby activating the variable displacement mechanism, which is beneficial to increasing the displacement of the constant pressure pump, thereby increasing the water pressure. Conversely, when the water pressure is higher than the set value, the control valve closes to shut down the variable displacement mechanism, thereby reducing the displacement of the constant pressure pump and lowering the water pressure, so as to achieve the purpose of constant water pressure and keep the water pressure always stable at the set water pressure required for sprinkling and fog cannon dust removal.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-3 , the present invention provides the following technical solutions: A cooling water recovery device for a mine exploitation and crushing device, including a water tank 1, a tank cover 2 is movably installed on the top of the water tank 1, a water inlet pipe 3 is movably installed on the surface of the tank cover 2, a drain port 4 is fixedly connected to the surface of the water tank 1, an overflow pipe 5 is flange-connected to one side of the drain port 4, a drain port 6 is fixedly connected to the surface of the water tank 1, a drain pipe 7 is flange-connected to one side of the drain port 6, a three-way pipe 8 is movably installed on the surface of the drain pipe 7, a drain pipe 9 is movably installed inside the three-way pipe 8, a valve 10 is movably installed on the surface of the drain pipe 7, a valve 11 is movably installed on the surface of the drain pipe 9, one end of the drain pipe 9 is flange-connected to a constant pressure pump 12, a variable displacement mechanism 13 is flange-connected to one side of the constant pressure pump 12, a pressure gauge 14 is fixedly installed on the surface of the variable displacement mechanism 13, a control valve 15 is fixedly installed inside the variable displacement mechanism 13, a control box 16 is fixedly installed on the surface of the constant pressure pump 12, a drain pipe 17 is flange-connected to one side of the variable displacement mechanism 13, and a valve 18 is movably installed on the surface of the drain pipe 17.

[0019] In this embodiment, through the setting of the water inlet pipe 3, it is convenient for the warm water discharged by the crusher to converge into the water tank 1. The water in the water tank 1 can be directly discharged through the drain port 6 and the drain pipe 7. After the valve 10 is closed, the water can enter the drain pipe 9 through the three-way pipe 8 for discharge. Through the setting of the constant pressure pump 12, it can detect the water pressure through the built-in pressure sensor. When the water pressure is lower than the set value, the pressure sensor transmits the signal to the control box 16, so that the controller built in the control box 16 controls the control valve 15 to open, thereby activating the variable displacement mechanism 13, which is beneficial to increasing the displacement of the constant pressure pump 12, thereby increasing the water pressure. On the contrary, when the water pressure is higher than the set value, the control valve 15 closes to shut down the variable displacement mechanism 13, thereby reducing the displacement of the constant pressure pump 12 and lowering the water pressure, so as to achieve the purpose of constant water pressure, and keep the water pressure always stable at the set water pressure required for sprinkling and dust suppression by the fog cannon.

[0020] Specifically, the drain port 4 and the overflow pipe 5 are located on the upper surface of the water tank 1, which is beneficial to the discharge of the excess water in the water tank 1 through the drain port 4 and the overflow pipe 5.

[0021] Specifically, a pressure sensor is provided inside the pipeline of the constant-pressure pump 12. The setting of the pressure sensor is conducive to real-time detection of the water pressure.

[0022] Specifically, the interior of the control box 16 includes a signal receiver, a signal processor, and a controller. The pressure sensor transmits the signal to the signal receiver inside the control box 16, then processes it through the signal processor, and then issues an instruction through the controller to control the opening and closing of the control valve 15, which is conducive to real-time adjustment of the water pressure.

[0023] Specifically, the number of the water inlet pipes 3 is several. The multiple settings of the water inlet pipes 3 are conducive to increasing the water inflow, thus avoiding the situation of income not meeting expenditure and preventing the constant-pressure pump 12 from being damaged.

[0024] Specifically, flange plates are provided at the connection ends of the first drain port 4 and the overflow pipe 5, the connection ends of the second drain port 6 and the first drain pipe 7, the connection ends of the second drain pipe 9 and the constant-pressure pump 12, the connection ends of the constant-pressure pump 12 and the variable displacement mechanism 13, and the connection ends of the variable displacement mechanism 13 and the third drain pipe 17. Bolts are installed inside the flange plates, and nuts are threadedly connected to the surfaces of the bolts. The setting of the flange plates is conducive to the tight connection between the pipelines. The use of bolts and nuts improves the connection stability and is convenient for disassembly.

[0025] The working principle or usage process of the present utility model: When the present utility model is in use, first, the warm water discharged by the crusher enters the water tank 1 through the water inlet pipe 3 and converges. The water in the water tank 1 can be directly discharged through the second drain port 6 and the first drain pipe 7. After the first valve 10 is closed, the second valve 11 is opened, and the water can enter the second drain pipe 9 through the three-way pipe 8 for discharge. Furthermore, the pressure sensor built in the constant-pressure pump 12 can detect the water pressure in real time. When the water pressure is lower than the set value, the pressure sensor transmits the signal to the inside of the control box 16, so that the controller built in the control box 16 controls the control valve 15 to open, thereby starting the variable displacement mechanism 13, which is conducive to increasing the displacement of the constant-pressure pump 12 and thus increasing the water pressure. On the contrary, when the water pressure is higher than the set value, the controller controls the control valve 15 to close, so that the variable displacement mechanism 13 is closed, thereby reducing the displacement of the constant-pressure pump 12 and lowering the water pressure, so as to achieve the purpose of constant water pressure and keep the water pressure always stable at the set water pressure required for sprinkling and fog cannon dust removal. The pressure gauge 14 can display the water pressure inside the variable displacement mechanism 13. Controlling the third valve 18 is conducive to controlling the opening and closing of the third drain pipe 17. Among them, the electrical equipment in this device is externally connected to the power supply and controlled to operate and shut down through the supporting control switch.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. This specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the relevant technical field can understand and utilize the present utility model well.
