[0029] Combine the following Figure 1-Figure 5 The present invention describes a mining water tank with ultrafiltration function. The mining water tank with ultrafiltration function comprises: a tank body 3, a water inlet component, an ultrafiltration component and a drainage component.

[0030] Among them, a water storage chamber is formed inside the box body 3, and a water inlet connected to the water storage chamber is formed on one side of the box body 3, and a drain connected to the water storage chamber is formed on the other side of the box body 3; the water inlet component is connected to the water inlet; the ultrafiltration component is arranged in the water storage chamber; the drain component passes through the drain port and is connected to the ultrafiltration component.

[0031] Specifically, a water storage cavity is formed inside the box 3 for water storage. Water enters the box 3 through the water inlet of the box 3 and is stored in the water storage cavity. Water is discharged through the water outlet of the box 3 and the water in the water storage cavity is sent to the water-using end through the water discharge assembly. The water storage system composed of the water inlet assembly, the box 3 and the water discharge assembly realizes the buffering water storage function of the water tank and can provide a stable water source output for the back-end water-using equipment.

[0032] Since there is an ultrafiltration component inside the water storage chamber, the water inside the water storage chamber is purified by the ultrafiltration effect of the ultrafiltration component under a negative pressure environment before being drained. Specifically, by suction on one side of the drain port of the box body 3, a negative pressure is formed inside the water storage chamber, and under the action of the negative pressure, the water is purified by ultrafiltration. Through the negative pressure environment formed by the ultrafiltration component and the inside of the water storage chamber, the water is ultrafiltered and purified, providing a pure water source output for the back-end water use equipment.

[0033] It can be seen that the present invention combines the water inlet component, the ultrafiltration component, the drainage component and the box body 3, so that the mining water tank has both the function of buffering water storage and ultrafiltration water purification, and can also provide stable and pure water source output for the back-end water equipment.

[0034] The present invention provides a mining water tank with ultrafiltration function, which includes: a box body 3, a water inlet component, an ultrafiltration component and a drainage component; a water storage cavity is formed inside the box body 3, and a water inlet connected to the water storage cavity is formed on one side of the box body 3, and a drainage port connected to the water storage cavity is formed on the other side of the box body 3; the water inlet component is connected to the water inlet; the ultrafiltration component is arranged in the water storage cavity; the drainage component passes through the drainage port and is connected to the ultrafiltration component. The water storage system composed of the water inlet component, the box body 3 and the drainage component realizes the buffering water storage function of the water tank, and at the same time can provide a stable water source output for the back-end water-using equipment; through the negative pressure environment formed by the ultrafiltration component and the inside of the water storage cavity, the water is ultrafiltered and purified, and a pure water source output is provided for the back-end water-using equipment. The mining water tank with ultrafiltration function provided by the present invention combines the water inlet component, the ultrafiltration component, the drainage component and the box body 3, so that the mining water tank has both a buffering water storage function and ultrafiltration water purification, and can also provide a stable and pure water source output for the back-end water-using equipment.

[0035] In one embodiment of the present invention, the water inlet assembly includes: a water inlet pipeline 2 and a water inlet valve 1. The water inlet pipeline 2 is connected to the water inlet; the water inlet valve 1 is arranged on the water inlet pipeline 2. Specifically, the water inlet pipeline 2 is connected to the water inlet of the box 3 and communicates with the water storage chamber, and the water inlet is controlled by the water inlet valve 1. Preferably, the water inlet valve 1 can be an electric valve.

[0036] In one embodiment of the present invention, the water inlet pipeline 2 has an outlet and at least two inlets 2.1, the outlet is connected to the water inlet, and the water inlet valve 1 is arranged near the outlet. In this embodiment, the water inlet pipeline 2 has multiple inlets 2.1 and one outlet, and each inlet 2.1 is respectively provided with a quick-connect connector to facilitate the connection of the pipeline of the water supply equipment. By providing multiple inlets 2.1, on the one hand, the box 3 can be quickly filled with water, and on the other hand, when one of the inlets 2.1 fails, water can be introduced through other inlets 2.1 to ensure normal water inlet. By providing the water inlet valve 1 at the outlet, the water inlet state of the water inlet pipeline 2 into the water storage chamber is controlled.

[0037] In one embodiment of the present invention, the drainage component includes: a drainage pipeline 5, a drainage valve 6 and a drainage pump 7. Among them, the drainage pipeline 5 is inserted into the drainage port and connected to the bottom of the ultrafiltration component; the drainage valve 6 is arranged on the drainage pipeline 5; the drainage pump 7 is arranged on the drainage pipeline 5. When the drainage pump 7 is working, a negative pressure is formed in the water storage chamber. In this embodiment, the drainage component is composed of the drainage pipeline 5, the drainage valve 6 and the drainage pump 7. The drainage pipeline 5 passes through the drainage port and is connected to the bottom of the ultrafiltration component. After the water in the water storage chamber is filtered by the ultrafiltration component, it is transported from the box 3 to the water-using end through the drainage pipeline 5. The drainage valve 6 is used to control the drainage state, and the drainage pump 7 is used to provide the negative pressure required for ultrafiltration. When the water-using end needs water, the drainage valve 6 and the drainage pump 7 are first opened. Under the negative pressure suction action of the drainage pump 7, the water in the box 3 is filtered by the ultrafiltration component due to the negative pressure action, and the drainage is purified.

[0038] Furthermore, the drainage pump 7 in the above embodiment adopts a one-in-use and one-in-standby design, that is, one drainage pump 7 is in use and the other drainage pump 7 is in standby. When water is supplied, only one drainage pump 7 is in operation and the other is in standby. When the drainage pump 7 adopts the above design, when one of the drainage pumps 7 is damaged, the damaged drainage pump 7 can be repaired by closing the drainage valve 6.

[0039] Specifically, one end of the drainage pipe 5 extends into the water storage chamber and is connected to the bottom of the ultrafiltration assembly, and the other end of the drainage pipe 5 extends from the box body 3. Since the ultrafiltration assembly can be a multi-layer structure, one end of the drainage pipe 5 is connected to each layer of the ultrafiltration assembly, and the water filtered by the ultrafiltration assembly is sent to the water use end through the drainage pipe 5. A drainage valve 6 and a drainage pump 7 are provided on the side of the drainage pipe 5 extending from the box body 3.

[0040] In one embodiment of the present invention, the mining water tank with ultrafiltration function further includes: a pressure gauge and a flow sensor. The pressure gauge is arranged at the water inlet end of the drainage pump 7; the flow sensor is arranged at the drainage end of the drainage pump 7. A pressure gauge is arranged at the water inlet end of the drainage pump 7, and a flow sensor is arranged at the drainage end of the drainage pump 7. By real-time monitoring of the value changes of the pressure gauge and the flow sensor, it is possible to detect whether the ultrafiltration component is blocked. If the value changes greatly, the ultrafiltration component may be blocked, and the ultrafiltration component needs to be cleaned to ensure its filtering effect and smooth drainage.

[0041] In one embodiment of the present invention, the drainage assembly further includes: a one-way valve 8, which is arranged on the drainage pipeline 5. In this embodiment, the function of the one-way valve 8 is to prevent the backflow of liquid when the water end is at a high position and the box body 3 is at a low position, thereby ensuring one-way drainage output.

[0042] In one embodiment of the present invention, the ultrafiltration component comprises: a plurality of ceramic membranes 4, the plurality of ceramic membranes 4 are arranged in sequence along the drainage direction, and a plurality of through holes are formed inside the ceramic membranes 4 for communicating with the drainage component. Figure 1 and Figure 4 As shown, the ultrafiltration component is composed of multiple ceramic membranes 4 arranged in sequence, and multiple ceramic membranes 4 can be filtered at the same time to improve the filtration efficiency. Figure 5 As shown, the ceramic membrane 4 is in the shape of a rectangular parallelepiped as a whole, with a smooth outer surface which is the filtering side, and a plurality of rectangular through holes inside to facilitate the outflow of filtered water, and the ceramic membrane 4 is connected to the drainage pipe 5 through the rectangular through holes. It should be understood that the drainage direction described in this embodiment is from the water inlet of the box body 3 to the drainage outlet.

[0043] In one embodiment of the present invention, the mining water tank with ultrafiltration function further includes: an overflow port 3.1, a sewage outlet 3.2 and an inspection port 3.3. The overflow port 3.1 is arranged on the outer wall of the box body 3 and is arranged near the top of the box body 3, and the overflow port 3.1 is connected to the water storage chamber; the sewage outlet 3.2 is arranged on the outer wall of the box body 3 and is arranged near the bottom of the box body 3, and the sewage outlet 3.2 is connected to the water storage chamber; the inspection port 3.3 is arranged on the box body 3 in an openable and closable manner, and corresponds to the position of the ultrafiltration component. In this embodiment, the overflow port 3.1 is provided to discharge the excess water in the box body 3. When the water storage chamber stores too much water, the overflow port 3.1 is opened to drain the water to prevent the box body 3 from expanding and deforming. When the ceramic membrane 4 is clogged with dirt, the water supply pump is turned off, and the water inlet valve 1 and the drain port 3.2 are opened. The pollutants trapped on the surface of the ceramic membrane 4 are flushed by the incoming water, and the flushed waste water is discharged from the drain port 3.2. The inspection port 3.3 is located directly above the ceramic membrane 4. When the ceramic membrane 4 needs to be chemically cleaned or replaced offline, the ceramic membrane 4 can be taken out by opening the inspection port 3.3.

[0044] In one embodiment of the present invention, the mining water tank with ultrafiltration function also includes: a sampling valve 3.5 and a liquid level sensor 3.4. Among them, the sampling valve 3.5 is arranged on the outside of the box body 3 and is connected to the water storage chamber; the liquid level sensor 3.4 is arranged on the outside of the box body 3, and the sensing end of the liquid level sensor 3.4 extends into the water storage chamber. The liquid level change in the water storage chamber can be observed by the liquid level sensor 3.4. At the same time, a sampling valve 3.5 is arranged below the liquid level sensor 3.4, which can sample and test the water quality in the water storage chamber. Preferably, the liquid level sensor 3.4 can adopt a magnetic flap level gauge.
