[0018] Beneficial effects of the present invention:

[0019] The environmentally friendly dust treatment device for open-pit mines described in the present invention relies on the wind force generated by the rotation of fan blades to drive the water sprayed from the atomizing nozzle to move upward, thereby forming a water curtain. When the dust in the open air of the mine comes into contact with the water, the dust and the water are adsorbed and fall from the air. The falling water is received by a water collecting structure and transported to a sedimentation structure. Impurities such as dust contained in the water are precipitated by the sedimentation structure. At the same time, the clean water after precipitation is transported to the atomizing nozzle again through a pumping pipe, thereby reducing the waste of water resources.

[0020] The environmentally friendly dust treatment device for open-pit mines described in the present invention, when the amount of falling water is large, relies on the pressure of the water on the polygonal water-collecting cloth to drive the sliding ring downward, and when the sliding ring moves downward, it drives the second moving ring downward, and when the second moving ring moves downward, two groups of steel cables are used to respectively drive the first moving ring at the lower end of the first sedimentation plate and the third sedimentation plate to move upward, thereby increasing the size of the turning angle position between the first sedimentation plate, the second sedimentation plate, and the third sedimentation plate, and increasing the water inlet speed of the water inlet channel, so that the water inlet amount of the water inlet channel can be automatically adjusted according to the amount of water sprayed by the atomizing nozzle.

[0021] The environmentally friendly dust treatment device for open-pit mines described in the present invention has a density of dust greater than that of water, so that the dust accumulates in the lower part of the water inlet channel and falls on the upper surface of the sealing plate. When the dust impurities accumulated on the upper surface of the sealing plate reach a certain amount, the sealing plate is driven downward by the dead weight of the dust. When the sealing plate moves downward, the impurities accumulated on the surface of the sealing plate will be mixed with the water in the sedimentation cylinder and discharged from the sewage pipe, thereby facilitating the cleaning of the dust impurities accumulated on the sealing plate and ensuring the subsequent sedimentation effect.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] In order to facilitate dust treatment in the mining area, precipitate the dust and reduce the waste of water resources, as an embodiment of the present invention, Figure 1-5 As shown, an environmentally friendly dust treatment device for an open-pit mine of the present invention comprises a vertically arranged fog cannon 1, a plurality of groups of circumferentially distributed atomizing nozzles 2 are arranged at the upper end of the fog cannon 1, a wind motor 3 is fixedly connected to the inside of the fog cannon 1, a plurality of groups of circumferentially distributed fan blades 4 are fixedly connected to the output end of the wind motor 3, a support tube 5 is fixedly connected to one end of the fog cannon 1 away from the atomizing nozzle 2, a water pump 6 is fixedly connected to the support tube 5, a vertically arranged water pump 7 is arranged at the lower end of the water pump 6, a water outlet pipe 8 is arranged at the upper end of the water pump 6, and the water outlet pipe 8 is connected to the plurality of groups of atomizing nozzles 2 through pipelines;

[0038] The lower end of the support cylinder 5 is provided with a sedimentation structure, the outer side of the sedimentation structure is detachably connected with a circumferentially distributed water collection structure, the water collection structure is connected with the sedimentation structure, and the lower end of the sedimentation structure is provided with a sewage discharge structure;

[0039] The lower end of the water pumping pipe 7 passes through the sedimentation structure and is located inside the sedimentation structure. A water inlet structure is provided outside the sedimentation structure, and one end of the water inlet structure passes through the sedimentation structure and is located inside the sedimentation structure.

[0040] When in use, when it is necessary to treat dust in the mining area, the water source is connected to the water inlet structure, and the water source enters the sedimentation structure through the water inlet structure. At the same time, the water in the sedimentation structure is pumped into the water pump 6 by the water pump pipe 7 of the water pump 6, and the water is transported to several groups of atomizing nozzles 2 through the water outlet pipe 8 and the pipeline, and finally sprayed out from the atomizing nozzle 2. When the water is sprayed out from the atomizing nozzle 2, the fan blades 4 are driven to rotate by the wind motor 3, and the wind force generated by the rotation of the fan blades 4 drives the water sprayed from the atomizing nozzle 2 to move upward, thereby forming a water curtain. After the open-air dust contacts the water body, the dust is adsorbed by the water body and falls from the air. The falling water body is received by the water collection structure and transported to the sedimentation structure. The dust and other impurities contained in the water body are precipitated by the sedimentation structure. At the same time, the clean water body after precipitation is transported to the atomizing nozzle 2 again through the pumping pipe 7, thereby reducing the waste of water resources. At the same time, the dust and other impurities precipitated in the precipitation structure can be discharged by the sewage discharge structure, thereby facilitating the dust treatment in the mining area and precipitating the dust, thereby reducing the waste of water resources.

[0041] It should be pointed out that when the fan blades 4 rotate, the surrounding air can be driven to flow, thereby improving the adsorption effect of the water sprayed by the atomizing nozzle 2 on impurities such as dust.

[0042] In order to facilitate the precipitation of impurities in the water body, for example, Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the present invention also includes that the sedimentation structure includes a vertically arranged sedimentation cylinder 9, and the inside of the sedimentation cylinder 9 is sequentially sleeved with an annular first sedimentation plate 10, a second sedimentation plate 11, and a third sedimentation plate 12 from the outside to the inside, and a water storage cylinder 13 is provided in the middle of the sedimentation cylinder 9, and the water storage cylinder 13 is located inside the third sedimentation plate 12, and the first sedimentation plate 10 and the second sedimentation plate 11, the second sedimentation plate 11 and the third sedimentation plate 12, and the third sedimentation plate 12 and the water storage cylinder 13 are all fixedly connected by a first connecting block 14, and the side of the first sedimentation plate 10 close to the sedimentation cylinder 9 is fixedly connected to the inner wall of the sedimentation cylinder 9 by a second connecting block 15, and the first sedimentation plate 10, the second sedimentation plate 11, and the third sedimentation plate 12 are staggered up and down to form a circuitous water inlet channel 16;

[0043] The upper end surfaces of the first sedimentation plate 10 and the third sedimentation plate 12 are higher than the upper end surface of the second sedimentation plate 11, and the lower end surfaces of the first sedimentation plate 10 and the third sedimentation plate 12 are higher than the lower end surface of the second sedimentation plate 11;

[0044] A support plate 17 is provided at the upper part of the sedimentation cylinder 9, and the upper ends of the first sedimentation plate 10 and the third sedimentation plate 12 are fixedly connected to the support plate 17. A plurality of support rods 18 are fixedly connected to the lower end of the support cylinder 5, and the lower ends of the support rods 18 are fixedly connected to the upper surface of the support plate 17. An annular water inlet 19 is provided between the support plate 17 and the sedimentation cylinder 9, and the lower end of the water pump 7 passes through the support plate 17 and is located in the water storage cylinder 13.

[0045] When in use, when water falls from the air, it falls on the water collecting structure, and the water collecting structure receives the falling water and transports it to the annular water inlet 19, and the water enters the sedimentation cylinder 9 through the annular water inlet 19. As the water continues to enter the sedimentation cylinder 9, when a certain amount of water enters the sedimentation cylinder 9, the water passes through the lower end of the first sedimentation plate 10 and enters between the first sedimentation plate 10 and the second sedimentation plate 11, and finally enters between the third sedimentation plate 12 and the second sedimentation plate 11 from the upper end of the second sedimentation plate 11, thereby forming a circuitous water inlet channel for the water. Since the water contains impurities such as dust, when the water passes through the water inlet channel 16, the dust and other impurities contained in the water will accumulate under the first sedimentation plate 10 and the third sedimentation plate 12, thereby precipitating the impurities in the water.

[0046] The settled water passes through the third settling plate 12 and enters the water storage cylinder 13. At this time, the settled water is transported to the atomizing nozzle 2 again by the pumping pipe 7 to treat the dust in the mining area and reduce the waste of water resources.

[0047] Since the density of dust is greater than that of water, dust accumulates below the water inlet channel 16. When the dust impurities in the water inlet channel 16 reach a certain amount, the dust discharge structure is opened by the dust's own weight, and the dust and other impurities that have been precipitated in the sedimentation cylinder 9 are discharged through the dust discharge structure, thereby ensuring the subsequent sedimentation effect.

[0048] By relying on several groups of first connecting blocks 14 and second connecting blocks 15, the stability of the first sedimentation plate 10, the second sedimentation plate 11, the third sedimentation plate 12 and the water collecting cylinder can be improved. At the same time, the first sedimentation plate 10 and the third sedimentation plate 12 can support the support plate 17, and by relying on several groups of support rods 18, the overall stability between the support cylinder 5 and the sedimentation cylinder 9 can be improved.

[0049] For example, Figure 4 , Figure 5 As shown, the present invention also includes that the water inlet structure includes a water inlet pipe 20, one end of the water inlet pipe 20 is connected to a water source, and the other end of the water inlet pipe 20 passes through the sedimentation cylinder 9, the first sedimentation plate 10, the second sedimentation plate 11, the third sedimentation plate 12 and the water storage cylinder 13 in sequence and is located in the water storage cylinder 13.

[0050] When in use, the water source is transported to the water storage cylinder 13 by means of the water inlet pipe 20, so as to ensure that the water pump 6 stably transports the water in the water storage cylinder 13 to the atomizing nozzle 2 through the pumping pipe 7, so as to process the dust.

[0051] In order to facilitate the reception of falling water, for example, Figure 1 , Figure 2 As shown, the present invention also includes that the water collection structure includes a sliding ring 21, the sliding ring 21 is located outside the sedimentation cylinder 9 and is slidably connected to the sedimentation cylinder 9, and a polygonal water collection cloth 22 is provided on the outside of the sliding ring 21. The polygonal water collection cloth 22 is formed by splicing a plurality of groups of waterproof cloths, and the corners of the polygonal water collection cloth 22 are detachably connected to a vertically arranged support frame 23;

[0052] An adjusting structure is provided inside the sedimentation cylinder 9, and the adjusting structure is used to adjust the size of the angular position of the water inlet channel 16. A driving structure is provided inside the sliding ring 21, and the driving structure is used to drive the adjusting structure.

[0053] When in use, the polygonal water collection cloth 22 is used to receive the falling water, and the received water is transported to the sedimentation cylinder 9 through the annular water inlet 19, so as to facilitate the sedimentation of the water.

[0054] When the amount of falling water is large, the gravity on the polygonal water-collecting cloth 22 increases, and the weight of the water drives the sliding ring 21 to move downward. When the sliding ring 21 moves downward, it drives the driving structure, and the driving structure drives the adjustment structure to operate, and the adjustment structure is used to adjust the size of the corner position of the water inlet channel 16, so as to improve the overall water inlet speed of the water inlet channel 16, and at the same time avoid the water flow speed at the corner position of the water inlet channel being too fast to affect the sedimentation effect, thereby preventing the water inlet channel from being difficult to ensure the sedimentation effect when the amount of falling water is large, and preventing the corner position of the water inlet channel from being too narrow to meet the water transportation demand, causing the water to overflow to the outside of the sedimentation cylinder 9, further improving the convenience of use; and based on the above scheme, the water inlet speed of the water inlet channel 16 can be automatically adjusted according to actual usage conditions;

[0055] It should be pointed out that the polygonal water-collecting cloth 22 of the present invention can be spliced ​​into a suitable size according to the actual use environment and site limitations, so as to facilitate the adjustment of the area for catching the falling water.

[0056] In order to automatically adjust the water inlet amount of the water inlet channel 16 according to the amount of water sprayed by the atomizing nozzle 2, for example, Figure 4 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11As shown, the present invention also includes that the adjustment structure includes two groups of first moving rings 24 and one group of second moving rings 25, the first moving rings 24 are each provided with a first sliding groove 26 opening upward, the second moving ring 25 is provided with a second sliding groove 27 opening downward, the lower ends of the first precipitation plate 10 and the third precipitation plate 12 correspond to the first sliding groove 26 respectively and are slidably connected to the first sliding groove 26, and the upper end of the second precipitation plate 11 corresponds to the second sliding groove 27 and is slidably connected to the second sliding groove 27;

[0057] The two sets of first moving rings 24 are fixedly connected to the second moving ring 25 through steel cables 28, and the two sets of steel cables 28 are supported by pulleys 29, and the two sets of pulleys 29 are installed on the lower surface of the support plate 17;

[0058] The driving structure is fixedly connected to the upper end of the second moving ring 25 , and the driving structure is used to drive the second moving ring 25 to move up and down.

[0059] When in use, when the amount of falling water is large, the pressure of the water on the polygonal water-collecting cloth 22 drives the sliding ring 21 downward, and when the sliding ring 21 moves downward, it drives the second moving ring 25 downward, and when the second moving ring 25 moves downward, it drives one end of the two sets of steel cables 28 downward, and relies on the action of the pulley 29 to make the other end of the two sets of steel cables 28 move upward, and thereby drives the first moving ring 24 at the lower end of the first sedimentation plate 10 and the third sedimentation plate 12 to move upward respectively, and when the first moving ring 24 moves upward, the size of the turning angle position between the first sedimentation plate 10, the second sedimentation plate 11, and the third sedimentation plate 12 is increased, and the water inlet speed of the water inlet channel 16 is increased, so that the water inlet amount of the water inlet channel 16 can be automatically adjusted according to the amount of water sprayed by the atomizing nozzle 2, thereby further improving the convenience of use.

[0060] In order to automatically adjust and reset the water inlet speed of the water inlet channel 16 according to actual usage, for example, Figure 4 , Figure 8 , Fig.10 , Fig.11 As shown, the present invention also includes that the driving structure includes a support ring 30 installed on the outside of the water pumping pipe 7, the support ring 30 is slidably connected to the outside of the water pumping pipe 7, a plurality of groups of horizontally arranged cross bars 31 are fixedly connected between the outside of the support ring 30 and the inside of the sliding ring 21, a plurality of groups of driving rods 32 are fixedly connected to the lower surface of the cross bars 31, the lower ends of the plurality of driving rods 32 all pass through the support plate 17 and are slidably connected to the support plate 17, the lower ends of the driving rods 32 are fixedly connected to the upper surface of the second movable ring 25, a spring rod 33 is fixedly connected to the outside of the sedimentation cylinder 9, and the upper end of the spring rod 33 is fixedly connected to the lower surface of the sliding ring 21.

[0061] When in use, after the water falls into the polygonal water collecting cloth 22, the sliding ring 21 can be driven to move downward appropriately. When the sliding ring 21 moves downward, the spring rod 33 is squeezed to move downward. At this time, the spring rod 33 squeezes and stores force; at the same time, when the sliding ring 21 moves downward, the cross bar 31 is driven downward, and when the cross bar 31 moves downward, the driving rod 32 is driven downward, and when the driving rod 32 moves downward, the second moving ring 25 is squeezed and driven to move downward synchronously, so as to adjust the water inlet speed of the water inlet channel 16. At the same time, the movement stability of the cross bar 31 can be improved by relying on the function of the support ring 30.

[0062] When the weight of the polygonal water-collecting cloth 22 is reduced after the water falls, the sliding ring 21 is driven upward by the resetting effect of the spring rod 33, and when the sliding ring 21 moves upward, the cross bar 31 is driven upward, and when the cross bar 31 moves upward, the second moving ring 25 is driven upward, and when the second moving ring 25 moves upward, one end of the steel cable 28 is no longer pulled down, so that the second moving ring 25 is restored to its initial state. At this time, the other end of the steel cable 28 no longer pulls up the first moving ring 24, and the first moving ring 24 at the lower end of the first sedimentation plate 10 and the third sedimentation plate 12 is moved down and restored to its initial state by relying on its own weight. In this way, the water inlet speed of the water inlet channel 16 can be automatically adjusted and reset according to actual usage.

[0063] In order to facilitate the cleaning of dust and impurities accumulated on the sealing plate 36, for example, Figure 2 , Fig.10 , Fig.12 As shown, the present invention also includes that the sewage discharge structure includes a support seat 34, the sedimentation cylinder 9 is located above the support seat 34 and is fixedly connected to the support seat 34, a sewage discharge chamber 35 connected to the sedimentation cylinder 9 is provided in the support seat 34, and a horizontally arranged sealing plate 36 is provided in the sewage discharge chamber 35. In the initial state, the upper surface of the sealing plate 36 is in compression contact with the lower surface of the sedimentation cylinder 9, and a plurality of groups of reset springs 37 are fixedly connected to the side of the sealing plate 36 away from the sedimentation cylinder 9, and the other end of the reset spring 37 is fixedly connected to the inner wall of the sewage discharge chamber 35, and a sewage discharge pipe 38 is provided on one side of the support seat 34, and one end of the sewage discharge pipe 38 is connected to the inside of the sewage discharge chamber 35.

[0064] During use, since the density of dust is greater than that of water, dust accumulates at the lower part of the water inlet channel 16 and falls on the upper surface of the sealing plate 36. When the dust impurities accumulated on the upper surface of the sealing plate 36 reach a certain amount, the sealing plate 36 is driven downward by the deadweight of the dust. When the sealing plate 36 moves downward, the impurities accumulated on the surface of the sealing plate 36 are mixed with the water in the sedimentation cylinder 9 and discharged from the sewage pipe 38, so as to facilitate the cleaning of the dust impurities accumulated on the sealing plate 36 and ensure the subsequent sedimentation effect.

[0065] When the sealing plate 36 moves downward to discharge the dust through the drain pipe 38, the sealing plate 36 is moved upward and reset by relying on the reset effect of the reset spring 37. After the sealing plate 36 moves upward and resets to the initial state, the upper surface of the sealing plate 36 is squeezed and contacted with the lower surface of the sedimentation cylinder 9 again, thereby sealing the bottom of the sedimentation cylinder 9 and facilitating the subsequent cleaning of dust and other impurities on the sealing plate 36.

[0066] In order to automatically adjust the water inlet of the water inlet pipe 20 according to the actual use situation, for example, Fig. 9 As shown, the present invention also includes that a water inlet valve 39 with a float switch is provided at one end of the water inlet pipe 20 located in the water storage cylinder 13.

[0067] When in use, after the water enters the water storage cylinder 13 through the water inlet pipe 20, the water that has been precipitated also enters the water storage cylinder 13 through the water inlet channel 16. At this time, the water level in the water storage cylinder 13 rises. When the water volume in the water storage cylinder 13 reaches a certain position, the water drives the float switch to move upward to reduce the water inlet of the water inlet pipe 20, thereby preventing the water volume in the water storage cylinder 13 from being too high, and the pumping speed of the pumping pipe 7 cannot be satisfied, resulting in a reduction in the sedimentation effect of the sedimentation cylinder 9.

[0068] When the water level of the water storage cylinder 13 decreases, the float switch moves downward to increase the water inlet of the water inlet pipe 20 and transports the water to the water storage cylinder 13 to meet the water pumping demand of the pumping pipe 7. In this way, the water inlet of the water inlet pipe 20 can be automatically adjusted according to actual usage.

[0069] When the present invention is used, when it is necessary to treat dust in a mining area, the water source is transported to the water storage cylinder 13 by means of the water inlet pipe 20, the water in the water storage cylinder 13 is pumped into the water pump 6 by means of the water pump pipe 7 of the water pump 6, and the water is transported to a plurality of groups of atomizing nozzles 2 through the water outlet pipe 8 and the pipeline, and finally sprayed out from the atomizing nozzle 2. When the water is sprayed out from the atomizing nozzle 2, the fan blades 4 are driven to rotate by driving the wind motor 3, and the water sprayed from the atomizing nozzle 2 is driven by the wind force generated by the rotation of the fan blades 4 to move upward, thereby forming a water curtain. When the open-air dust in the mining area contacts the water, the dust is adsorbed by the water and falls from the air.

[0070] The polygonal water-collecting cloth 22 is used to receive the falling water, and the received water is transported to the sedimentation cylinder 9 through the annular water inlet 19. When the water enters the sedimentation cylinder 9 through the annular water inlet 19, the water is located between the first sedimentation plate 10 and the inner wall of the sedimentation cylinder 9. As the water continues to enter the sedimentation cylinder 9, when a certain amount of water enters the sedimentation cylinder 9, the water passes through the lower end of the first sedimentation plate 10 and enters between the first sedimentation plate 10 and the second sedimentation plate 11, and finally enters between the third sedimentation plate 12 and the second sedimentation plate 11 from the upper end of the second sedimentation plate 11, thereby forming a circuitous water inlet channel for the water. Since the water contains impurities such as dust, when the water passes through the water inlet channel 16, the dust and other impurities contained in the water will accumulate under the first sedimentation plate 10 and the third sedimentation plate 12, thereby precipitating the impurities in the water.

[0071] The settled water enters the water storage cylinder 13 through the third settling plate 12. At this time, the settled water is transported to the atomizing nozzle 2 again by the pumping pipe 7 to treat the dust in the mining area and reduce the waste of water resources.

[0072] When the amount of falling water is large, the gravity on the polygonal water-collecting cloth 22 increases, and the sliding ring 21 is driven downward by the weight of the water. When the sliding ring 21 moves downward, it squeezes the spring rod 33 to move downward. At this time, the spring rod 33 squeezes and stores force; at the same time, when the sliding ring 21 moves downward, it drives the cross bar 31 downward, and when the cross bar 31 moves downward, it drives the driving rod 32 downward. When the driving rod 32 moves downward, it squeezes the second moving ring 25 and drives the second moving ring 25 to move downward synchronously. When the second moving ring 25 moves downward, it drives one end of the two sets of steel cables 28 downward. The other ends of the two sets of steel cables 28 are moved upward by the action of the pulley 29, and the first movable rings 24 at the lower ends of the first sedimentation plate 10 and the third sedimentation plate 12 are respectively driven upward. When the first movable ring 24 moves upward, the size of the turning angle between the first sedimentation plate 10, the second sedimentation plate 11, and the third sedimentation plate 12 is increased, and the water inlet speed of the water inlet channel 16 is increased, so that the water inlet amount of the water inlet channel 16 can be automatically adjusted according to the water amount sprayed by the atomizing nozzle 2, further improving the convenience of use;

[0073] Since the density of dust is greater than that of water, dust accumulates at the bottom of the water inlet channel 16 and falls on the upper surface of the sealing plate 36. When the dust impurities accumulated on the upper surface of the sealing plate 36 reach a certain amount, the sealing plate 36 moves downward by relying on the deadweight of the dust. When the sealing plate 36 moves downward, the impurities accumulated on the surface of the sealing plate 36 will mix with the water in the sedimentation cylinder 9 and be discharged from the sewage pipe 38, so as to facilitate the cleaning of the dust impurities accumulated on the sealing plate 36 and ensure the subsequent sedimentation effect.

[0074] When the sealing plate 36 moves downward to discharge the dust through the drain pipe 38, the sealing plate 36 is moved upward and reset by relying on the reset effect of the reset spring 37. After the sealing plate 36 moves upward and resets to the initial state, the upper surface of the sealing plate 36 is squeezed and contacted with the lower surface of the sedimentation cylinder 9 again, thereby sealing the bottom of the sedimentation cylinder 9 and facilitating the subsequent cleaning of dust and other impurities on the sealing plate 36.
