Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water supply technology for mine backfilling stations, and relates to a water supply device for mine backfilling. Background Technology
[0002] In mine backfilling stations, to facilitate construction and reduce costs, most backfilling station water storage tanks are excavated underground, while the water-using equipment for the backfilling system is mostly built above ground. To ensure the normal operation of the backfilling process, the existing water supply system mainly uses pumps to pressurize and transport water from the storage tanks to the water-using equipment above ground. This requires not only pump facilities and electricity supply, but also regular maintenance and replacement of components in the water supply equipment. The pump facilities also generate noise pollution during operation. Furthermore, during mining operations, the water storage tanks often contain silt and sand. After a period of use, this settled silt and sand accumulates at the bottom of the buffer tank, increasing the difficulty and workload of cleaning. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an automatic water supply device for mine filling, which realizes automatic water supply by using the siphon principle without the need for water pump facilities and power supply, thereby achieving the purpose of energy saving, noise reduction and maintenance reduction.
[0004] The technical solution of this utility model is as follows:
[0005] An automatic water supply device for mine backfilling includes a water-using unit and a water storage tank for supplying water to the water-using unit. The top surface of the water-using unit is lower than the lowest water level of the water storage tank. The water supply device also includes a buffer tank. A water supply pipe with a water supply valve is installed at the top of the buffer tank. An exhaust pipe with an exhaust valve is also installed at the top of the buffer tank. A water inlet is provided at the top of the buffer tank, and a water inlet pipe is connected to the water inlet. The water inlet end of the water inlet pipe is located below the water level of the water storage tank. A guide plate with a water passage gap between its lower end and the bottom plate of the buffer tank is fixedly installed on the top plate of the buffer tank. A guide plate with an upper end connected to the buffer tank is fixedly installed on the bottom plate of the buffer tank. The top plates of the tank have partitions with water passage gaps; the lower end of the guide plate is lower than the upper end of the partition; the space between the guide plate and the side plate of the buffer tank is the first chamber, the space between the guide plate and the partition is the second chamber, and the space between the partition and the side plate of the buffer tank is the third chamber; the inlet is located on the top plate of the buffer tank at the upper end of the first chamber; the side plate of the buffer tank has a mud and sand discharge port that communicates with the lower end of the first chamber, and the mud and sand discharge port is connected to a mud and sand discharge pipe with a mud discharge valve; the side plate of the buffer tank has a drain port that communicates with the lower end of the third chamber, and the drain port is connected to a drain pipe whose lower end is used to connect to the water-using unit.
[0006] As a further improvement of this utility model, a first one-way check valve is installed on the water inlet pipe.
[0007] As a further improvement of this utility model, a flow meter for detecting the inlet flow rate is installed on the inlet pipe between the inlet and the first one-way check valve.
[0008] As a further improvement of this utility model, both the guide plate and the baffle are arranged perpendicular to the horizontal plane.
[0009] As a further improvement of this utility model, a third one-way check valve is installed on the mud discharge pipe between the mud discharge port and the mud discharge valve.
[0010] As a further improvement of this utility model, a second one-way check valve is installed on the drain pipe.
[0011] As a further improvement of this utility model, the installation height of the second one-way check valve is lower than the lowest water level of the water storage tank.
[0012] As a further improvement of this utility model, a drain regulating valve is provided on the drain pipe between the drain outlet and the second one-way check valve.
[0013] As a further improvement of this utility model, a level gauge for monitoring the water level of the water storage tank is installed above the water storage tank.
[0014] Compared with the prior art, the present invention has the following advantages:
[0015] (1) This utility model achieves automatic water supply by setting up a high-level buffer water tank next to the water storage tank, a first one-way check valve sealed to the buffer water tank and installed on the water inlet pipe, a second one-way check valve installed on the water outlet pipe, and a third one-way check valve installed on the mud and sand discharge pipe. It does not require the use of water pump facilities and power supply, thus achieving the purpose of energy saving, noise reduction and maintenance reduction.
[0016] (2) By setting a guide plate and a baffle in the buffer tank, the buffer tank is divided into an independent first chamber, a second chamber and a third chamber. A mud and sand discharge port is set at the bottom of the first chamber and the second chamber. The water entering from the reservoir first flows through the first chamber and the second chamber. During the downward and upward flow of the water, some mud and sand settle to the bottom mud and sand discharge port and are discharged from the system through the mud and sand discharge port, which reduces the difficulty of cleaning mud and sand in the system and the amount of cleaning work.
[0017] (3) This device is also easy to install and implement. Attached Figure Description

Detailed Implementation
[0020] The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings.
[0021] like Figure 1 An embodiment of an automatic water supply device for mine backfilling includes a water storage tank 4 and a rectangular buffer tank 3 installed beside the water storage tank 4 via a fixed support 10. The height difference between the buffer tank 3 and the water storage tank 4 generally does not exceed 2 meters. A stirring tank 9, serving as a water-using unit, is provided beside the buffer tank 3. The top surface of the stirring tank 9 is lower than the minimum operating water level of the water storage tank 4.
[0022] The buffer tank 3 has a water inlet at its top, to which a water supply pipe is connected. A water supply hopper 1 is installed on the water supply pipe, and a water supply valve 2 is installed on the water supply pipe between the water inlet and the water supply hopper 1. The buffer tank 3 also has a vent at its top, to which a vent pipe is connected, and a vent valve 6 is installed on the vent pipe. The buffer tank 3 also has a water inlet at its top, to which a water inlet pipe is connected. The water inlet of the water inlet pipe is located at the bottom of the water storage tank 4, and a first one-way check valve 5 is installed on the water inlet pipe. To ensure the continuous automatic operation of the automatic water supply device for mine backfilling, a flow meter 11 for detecting the inlet flow rate is installed on the water inlet pipe between the water inlet and the first one-way check valve 5.
[0023] A guide plate 16 with a certain water passage distance between its lower end and the bottom plate of the buffer tank 3 is fixedly installed on the top plate of the buffer tank 3. A partition plate 12 with a certain water passage distance between its upper end and the top plate of the buffer tank 3 is fixedly installed on the bottom plate of the buffer tank 3. The lower end of the guide plate 16 is lower than the upper end of the partition plate 12.
[0024] The space between the guide plate 16 and the side plate of the buffer tank 3 is the first chamber, the space between the guide plate 16 and the partition plate 12 is the second chamber, and the space between the partition plate 12 and the side plate of the buffer tank 3 is the third chamber. Both the guide plate 16 and the partition plate 12 are perpendicular to the horizontal plane. The water inlet is located on the top plate of the buffer tank 3 at the upper end of the first chamber.
[0025] The side plate of the buffer tank 3 is provided with a mud and sand discharge port that communicates with the lower end of the first chamber. The mud and sand discharge port is connected to a mud and sand discharge pipe. A mud and sand discharge valve 14 is installed at the outer end of the mud and sand discharge pipe. A third one-way check valve 13 is installed on the mud and sand discharge pipe between the mud and sand discharge port and the mud and sand discharge valve 14.
[0026] The side plate of the buffer tank 3 is also provided with a drain outlet communicating with the lower end of the third chamber. This drain outlet is connected to a drain pipe whose lower end is used to connect to the stirring tank 9. A second one-way check valve 7 is installed on this drain pipe. The installation height of the second one-way check valve 7 is lower than the minimum operating water level of the water storage tank 4. A drain regulating valve 8 is provided on the drain pipe between the drain outlet and the second one-way check valve 7, which can automatically adjust the drain flow rate according to the flow rate of the inlet pipe.
[0027] A level gauge 15 for monitoring the water level of the water storage tank 4 can also be installed above the water storage tank 4. When the water level of the water storage tank 4 drops to near the minimum operating water level of this device, and the reading of the level gauge 15 reaches the set value, the water supply to the buffer tank 3 through this automatic water supply device will be stopped, and water will be replenished to the water storage tank 4 in a timely manner. After the water storage tank 4 has been replenished, the automatic water supply device can be restarted.
[0028] Water in the reservoir 4 rises through the inlet pipe into the buffer tank 3, and then flows sequentially through the first chamber, the second chamber, and the third chamber within the buffer tank 3. Finally, it is discharged to the water-using unit (in this embodiment, the mixing tank 9) through the outlet pipe. Water entering the buffer tank 3 first flows through the first and second chambers. During the process of the water descending in the first chamber and rising in the second chamber, some sediment settles to the bottom sediment discharge port and is discharged from the system through it.
[0029] All components of the automatic water supply device of this utility model, including the housing, valves, pipelines, and connectors, are sealed to ensure the overall airtightness of the device.
[0030] When supplying water using the device described in this embodiment, first open the water supply valve 2 and the air vent valve 6, and close the water discharge regulating valve 8 and the sludge discharge valve 14. Add water to the buffer tank 3 through the water supply hopper 1, and stop adding water when the buffer tank 3 is completely filled with water and water flows out of the air vent pipe. Close the air vent valve 6 and the water supply valve 2 to keep the buffer tank 3 in a closed state. Then open the water discharge regulating valve 8, and the water in the water storage tank 4 flows to the stirring tank 9 by means of siphon.
[0031] The design of this device is based on the water supply requirements of the filling system, including the required inlet pipe diameter, buffer tank 3 volume, and outlet pipe diameter. If the water supply is large, two or more sets of this device can be designed. Seamless steel pipes are preferred for the connecting pipelines of this device.
[0032] In addition to supplying water to the filling and mixing tank 9, this device can also supply water to other equipment on site or to other operations such as on-site sanitation and cleaning.
[0033] It should be noted that, as will be apparent to those skilled in the art, this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. The scope of this utility model is defined by the claims rather than the foregoing description.
