[0001] The present invention belongs to the field of tailings pond environmental management, and in particular relates to a water spraying system for preventing sand and dust on a dry beach of a tailings pond and a use method thereof. Background Art

[0002] Tailings ponds consist of a dam, dry beach, and reservoir. The dry beach is formed by the natural accumulation of tailings from the beneficiation plant. The tailings are fine-grained, and during dry and rainy seasons, winds can cause dust to fly, polluting the environment. Furthermore, the dry beach is large and difficult to manage. Summary of the Invention

[0003] The purpose of the present invention is to provide a water spraying system for preventing sand and dust on the dry beach of a tailings pond, so as to solve the problem of dust on the dry beach.

[0004] Another object of the present invention is to provide a method for using a water spraying system for preventing sand and dust on the dry beach of a tailings pond.

[0005] The technical solution of the present invention is: a water spraying system for preventing sand and dust on the dry beach of a tailings pond, comprising a water spraying pipe network and an air pipe network, the water spraying pipe network covering the dry beach surface of the tailings pond, the water spraying pipe network connected to a water intake pump, a plurality of water spraying heads arranged on the water spraying pipe network, the air pipe network located below the water spraying pipe network, the air pipe network connected to an air compressor, a plurality of rubber balls filled with gas arranged at the bottom of the air pipe network, the rubber balls supporting the air pipe network and the water spraying pipe network, the rubber balls being connected to the air pipe network, and an exhaust valve being provided on the air pipe network.

[0006] As a further improvement of the present invention, it also includes a water intake floating boat, which floats on the surface of the tailings reservoir, and the water intake pump is installed on the bottom of the water intake floating boat.

[0007] As a further improvement of the present invention, a hemispherical shell is provided on the upper part of the rubber ball, the shell covers the rubber ball and is connected to the outer surface of the rubber ball, and the top of the shell is connected to the air pipe network.

[0008] As a further improvement of the present invention, the water spray pipe network and the air pipe network are connected via a connector.

[0009] As a further improvement of the present invention, the water intake pump, the air compressor and the exhaust valve are all connected to the control center, which facilitates the control of the opening and closing of the water intake pump, the air compressor and the exhaust valve.

[0010] A method for using a water spray system for preventing sand and dust on a dry beach of a tailings pond comprises the following steps:

[0011] A. Intermittently open the water pump to draw water, and the water pipe network will transport water to each sprinkler head. The sprinkler head will spray water on the dry beach to prevent wind and sand. After the spraying is completed, close the water pump;

[0012] B. When the tailings on the dry beach accumulate to the bottom of the buried rubber balls, turn on the air compressor and inflate the rubber balls through the air pipe network. After the rubber balls expand, they break away from the tailings and automatically move upward to the surface of the dry beach, thereby driving the air pipe network and the water spray pipe network to move upward to prevent the sprinkler heads from being buried by the tailings. Then turn off the air compressor and open the exhaust valve to restore the rubber balls to their original inflation level.

[0013] A water spray system for preventing sand and dust on the dry beach of a tailings pond comprises a water spray network and an air network. The water spray network covers the dry beach surface of the tailings pond and is connected to a water pump. Multiple water spray heads are arranged on the water spray network. The air network is located below the water spray network and is connected to an air compressor. Multiple rubber balls filled with gas are connected to the bottom of the air network. The rubber balls are isolated from the air network and are connected to multiple air injection pipes at the bottom of the air network. The rubber balls provide support for the air and water network.

[0014] As a further improvement of the present invention, it also includes a water intake floating boat, which floats on the surface of the tailings reservoir, and the water intake pump is installed on the bottom of the water intake floating boat.

[0015] As a further improvement of the present invention, the water spray pipe network and the air pipe network are connected via a connector; the water intake pump and the air compressor are both connected to the control center.

[0016] A method for using a water spray system for preventing sand and dust on a dry beach of a tailings pond comprises the following steps:

[0017] A. Intermittently open the water pump to draw water, and the water pipe network will transport water to each sprinkler head. The sprinkler head will spray water on the dry beach to prevent wind and sand. After the spraying is completed, close the water pump;

[0018] B. When the tailings on the dry beach accumulate to the bottom of the buried rubber ball, turn on the air compressor and deliver compressed air to each jet pipe through the air pipe network. The jet pipes will spray downward. Under the thrust of the compressed air, the air pipe network will drive the water spray pipe network and the rubber ball to move upward. Then turn off the air compressor, and the air pipe network, water spray pipe network and rubber ball will fall back to the surface of the dry beach.

[0019] The beneficial effects of the present invention are:

[0020] 1. The present invention covers the dry beach surface with a water spraying network and arranges multiple water sprinklers on the water spraying network. Water is drawn locally from the reservoir by a water intake floating boat and a water intake pump to spray the dry beach surface. The spraying range is comprehensive and can effectively prevent sand and dust.

[0021] 2. During the use of the tailings pond, new tailings are constantly accumulated on the dry beach surface. To prevent the water spray network from being buried, the present invention provides an air pipe network and a rubber ball below the water spray network. The rubber ball supports the air pipe network, which in turn supports the water spray network. The rubber ball can be connected to or disconnected from the air pipe network. If the rubber ball is connected to the air pipe network, and the lower part of the rubber ball is buried by tailings, the air compressor is turned on to inflate the rubber ball. After the rubber ball expands, it breaks free from the tailings and automatically moves upward to the dry beach surface, thereby driving the air pipe network and the water spray network upward, preventing the water spray network and the sprinkler heads thereon from being buried by tailings. The air compressor is then turned off and the exhaust valve is opened to properly exhaust the rubber ball and restore it to its original inflation level. If the rubber ball is not connected to the air pipe network, multiple air jets are installed in the air pipe network. When the lower part of the rubber ball is buried by tailings, the air compressor is turned on and the air jets are ejected downward. Under the thrust of the compressed air, the air pipe network drives the water pipe network and the rubber ball upward. When the air compressor is turned off, the air pipe network, the water pipe network and the rubber ball will fall back to the surface of the dry beach, thus preventing the water pipe network and the sprinkler heads on it from being buried by tailings. The rubber ball is elastic and acts as a cushion when it falls.

[0022] 3. The opening and closing of the water pump, air compressor and exhaust valve in the present invention can be controlled by the control center, which is easy to operate. In addition, the water spraying time and water spraying interval can be set in the control center, reducing manual operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1: "Self-elevating" water spraying system.

[0036] like Figures 1-4 As shown, a water spraying system for preventing sand and dust on the dry beach of a tailings pond includes a water spraying network 3 and an air pipe network 5. The water spraying network 3 covers the surface of the dry beach 10 of the tailings pond and is connected to a water intake pump 2. Multiple water spray heads 4 are arranged on the water spraying network 3. The air pipe network 5 is located below the water spraying network 3 and is connected to an air compressor 6. Multiple rubber balls 7 are arranged at the bottom of the air pipe network 5. The rubber balls 7 are filled with gas and are connected to the air pipe network 5. The air pipe network 5 is provided with an exhaust valve 12. The exhaust valve 12 is close to the air compressor 6.

[0037] The water intake floating vessel 1 is also included. The water intake floating vessel 1 floats on the surface of the tailings reservoir 11 . A water intake pump 2 is installed at the bottom of the water intake floating vessel 1 .

[0038] The water spray pipe network 3 and the air pipe network 5 are connected via a connector 13 .

[0039] The water intake pump 2, the air compressor 6 and the exhaust valve 12 are all connected to the control center.

[0040] The structure of the air pipe network 5 is as follows Figure 4 As shown, it is composed of multiple horizontal and vertical pipes that are interconnected to ensure that the compressed air enters each rubber ball 7 smoothly and evenly.

[0041] Here’s how to use it:

[0042] A. The control center intermittently activates the water pump 2 to draw water. The water pipe network 3 delivers the water to the sprinkler heads 4, which then spray the dry beach 10 to prevent wind and sand. The control center sets the operating hours and intermittent time of the water pump 2 to ensure that each spraying fully wets the surface of the dry beach 10. After the spraying is completed, the water pump 2 is shut down.

[0043] B. During the use of the tailings pond, new tailings are constantly accumulated on the dry beach 10. When the tailings on the dry beach 10 accumulate to the bottom of the buried rubber balls 7 (less than half the height of the rubber balls 7), the control center turns on the air compressor 6 and inflates each rubber ball 7 through the air pipe network 5. After the rubber balls 7 expand, they break away from the buried tailings and automatically move upward to the surface of the dry beach 10, thereby driving the air pipe network 5 and the water spray pipe network 3 to move upward to prevent the sprinkler head 4 from being buried by the tailings. The control center then turns off the air compressor 6, opens the exhaust valve 12 to properly exhaust the rubber balls 7 and restore them to their original inflation level, and then closes the exhaust valve 12.

[0044] In this embodiment, the tailings can be broken away by the expansion of the rubber ball 7, which automatically rises (the principle is as follows). Figure 5 as shown) to drive the entire water spray system upward.

[0045] Example 2: "Grab-up" water spray system.

[0046] like Figure 6 、 Figure 7 As shown, the difference between this embodiment and embodiment 1 is that a hemispherical shell 8 is provided on the upper part of the rubber ball 7, the shell 8 covers the rubber ball 7 and is connected to the outer surface of the rubber ball 7, and the top of the shell 8 is connected to the air pipe network 5.

[0047] The method of use of this embodiment is the same as that of embodiment 1. In this embodiment, a shell 8 is added between the rubber ball 7 and the air pipe network 5. The shell 8 covers the upper part of the rubber ball 7 and is connected to the outer surface of the rubber ball 7, forming a "grip" for the rubber ball. When the rubber ball 7 is inflated, its upper part does not expand under the "grip" of the shell 8, and only the lower part expands. The expansion of the lower part of the rubber ball 7 can not only help the rubber ball 7 to expand and break free from the burial of the tailings, but also form a thrust on the top of the rubber ball 7, pushing the shell 8 upward. When the shell 8 moves upward, it grabs the rubber ball 7 upward (the principle is as follows). Figure 8 ), thereby driving the entire sprinkler system upward.

[0048] Example 3, "jet" water spray system.

[0049] like Figure 9 、 Figure 10As shown, a water spray system for preventing sand and dust on the dry beach of a tailings pond includes a water spray network 3 and an air network 5. The water spray network 3 covers the surface of the dry beach 10 of the tailings pond and is connected to a water pump 2. Multiple water spray heads 4 are arranged on the water spray network 3. The air network 5 is located below the water spray network 3 and is connected to an air compressor 6. Multiple rubber balls 7 are connected to the bottom of the air network 5. The rubber balls 7 are filled with gas and are not connected to the air network 5. The bottom of the air network 5 is also connected to multiple air injection pipes 9. The rubber balls provide support for the air and water pipe networks.

[0050] The water intake floating vessel 1 is also included. The water intake floating vessel 1 floats on the surface of the tailings reservoir 11 . A water intake pump 2 is installed at the bottom of the water intake floating vessel 1 .

[0051] The water spray pipe network 3 and the air pipe network 5 are connected via a connector 13 .

[0052] The water intake pump 2 and the air compressor 6 are both connected to the control center.

[0053] In this embodiment, the structures of the water spray pipe network 3 and the air pipe network 5 are the same as those in embodiment 1.

[0054] Here’s how to use it:

[0055] A. The control center intermittently activates the water pump 2 to draw water. The water pipe network 3 delivers the water to the sprinkler heads 4, which then spray the dry beach 10 to prevent wind and sand. The control center sets the operating hours and intermittent time of the water pump 2 to ensure that each spraying fully wets the surface of the dry beach 10. After the spraying is completed, the water pump 2 is shut down.

[0056] B. When the tailings on the dry beach 10 accumulate to the bottom of the buried rubber ball 7 (less than half the height of the rubber ball 7), the air compressor 6 is turned on to supply compressed air to each jet pipe 9 through the air pipe network 5. The jet pipe 9 sprays air downward. Under the thrust of the compressed air, the air pipe network 5 drives the water spray pipe network 3 and the rubber ball 7 to move upward. Then the control center turns off the air compressor 6, and the air pipe network 5, the water spray pipe network 3 and the rubber ball 7 fall back to the surface of the dry beach 10. The rubber ball 7 acts as a buffer when falling back.

[0057] In this embodiment, the downward jetting through the jet pipe 9 generates an upward reaction force to drive the entire water spraying system upward.
