DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Example 1, reference Figure 1-4 A mining water sprinkling and dust suppression device comprises a water sprinkling box 6 and a blower body 1 symmetrically arranged at the upper end thereof: brackets 3 are symmetrically arranged on the upper part of the water sprinkling box 6, a water tank 4 is spanned between the upper ends of the two brackets 3, a plurality of sprinkler nozzles 19 are distributed in a linear array at the bottom of the water tank 4, a water pipe 5 is arranged on the upper part of the water tank 4, and the water tank 4 is connected to the water supply equipment through the water pipe 5, an air inlet 16 and an air outlet 17 are respectively arranged on the blower body 1, and the position of the air outlet 17 is just located between the two baffles 2.

[0028] A slot hole 7 is provided at the middle of the upper part of the watering box 6, and an oily dust auxiliary processing component is arranged inside the slot hole 7; the oily dust auxiliary processing component includes a stepper motor 18, a baffle 2, a dust-free cloth 8 and two symmetrically arranged rollers 23.

[0029] When the equipment is started, the blower bodies 1 on both sides are started, and the blower bodies 1 suck in dust from the air inlet 16 and discharge it from the air outlet 17. At this time, the water tank 4 at the upper end is connected to the water supply equipment through the water pipe 5, and the power switch of the water supply equipment is started, and water falls from the sprinkler nozzle 19, just in contact with the dust below. During the contact process, the water and dust mix and fall down.

[0030] The dust in the mine contains a large amount of oily dust. If this dust falls directly, it will adhere to the inner wall of the mine and have an impact on the later operation of the mine.

[0031] To this end, a slot 7 is provided in the middle of the upper end of the watering box 6, and rotatable rollers 23 are provided on both sides of the slot 7, and the dust-free cloth 8 is sleeved between the outer sides of the two rollers 23. When the dust and water contact each other and fall on the dust-free cloth 8, the dust-free cloth 8 has a high-efficiency adsorption characteristic and can adsorb the oily dust. At the same time, the water can pass through the dust-free cloth 8 and flow back into the watering box 6. By turning on the power of the stepper motor 18, one of the rollers 23 is driven to roll. During the rolling, the position of the dust-free cloth 8 above the slot 7 keeps changing. The purpose of this design is that the water inside the watering box 6 is always in a flowing state. When the dust-free cloth 8 with oily dust adhered to it rotates to the inner side of the watering box 6, it will contact the flowing water source. In this way, the flowing water source is used to clean the oily dust adhered to the surface of the dust-free cloth 8, and the oily dust is taken away with the water flow, so that the dust-free cloth 8 can work for a longer period of time, and the dust-free cloth 8 can adhere to the oily dust with the highest efficiency each time it works.

[0032] Example 2, reference Figure 4 The difference between this embodiment and embodiment 1 is that the roller 23 is rotatably arranged in the slot 7, the baffle 2 is parallelly installed on the upper part of the watering box 6, the dust-free cloth 8 is sleeved between the outer sides of the two rollers 23, and one of the rollers 23 is connected to the output shaft of the stepper motor 18, and the outer surface of the dust-free cloth 8 is provided with a strip-shaped groove 9, and the bottom of the groove 9 is arranged in an arc shape.

[0033] If the outer surface of the dust-free cloth 8 is designed to be flat, the surface area of ​​the dust-free cloth 8 on which oily dust can adhere will be limited.

[0034] To this end, a plurality of grooves 9 are provided on the surface of the dust-free cloth 8. The grooves 9 are provided on the surface of the dust-free cloth 8, which can effectively increase the surface area of ​​the dust-free cloth 8. The bottom thereof is provided in an arc shape, and oily dust can be concentratedly collected on the inner side of the grooves 9.

[0035] Example 3, reference Figure 7-8 The difference between this embodiment and Embodiment 1 and Embodiment 2 is that a cleaning assembly is also provided inside the sprinkler box 6, and the cleaning assembly includes a float 10, a water outlet 11, a water inlet 12, an elastic column 20, a partition 21 and a scraper assembly 22. The partition 21 is installed on both sides of the upper end of the float 10, and the water inlet speed of the water inlet 12 matches the water outlet speed of the water outlet 11. Specifically, the speed of the water inlet 12 and the sprinkler nozzle 19 matches the water outlet speed of the water outlet 11.

[0036] Both sides of the float 10 are connected to the inner side of the watering box 6 through a plurality of elastic columns 20. The water inlet 12 and the water outlet 11 are respectively provided on both sides of the watering box 6. The scraper assembly 22 is fixed on the upper end surface of the float 10, and the scraper assembly 22 is used to clean the oily dust collected in the groove 9. The dust-free cloth 8 extends through the lower part of the slot 7 into the watering box 6. When the equipment is running, the liquid level at the upper end of the watering box 6 just exceeds the bottom position of the dust-free cloth 8.

[0037] Although the arrangement of the groove 9 can increase the area in contact with the oily dust, the dust is concentrated on the inner side of the groove 9 , which increases the difficulty of cleaning the inner side of the groove 9 .

[0038] To this end, there is flowing water inside the sprinkler box 6, and a float 10 is arranged on the liquid surface. When the two ends of the float 10 are connected to the inner walls of the sprinkler box 6 through elastic columns 20, when the partitions 21 at both ends of the float 10 are hit by the water flow, the float 10 will be driven to move inside the sprinkler box 6. At the same time, the two side walls of the float 10 and the two side walls inside the sprinkler box 6 fit each other. During the movement of the float 10, the elastic column 20 can play a certain limiting role. When the float 10 reciprocates at the lower end of the groove 8, the oily substance in the groove 8 is scraped off by the scraper assembly 22 at its upper end.

[0039] Example 4, reference Figure 7-8 The difference between this embodiment and Embodiment 1, Embodiment 2 and Embodiment 3 is that the scraper assembly 22 includes oil-absorbing cotton 2201, a sphere 2202, a rotating shaft 2203, a supporting frame 2204, a rotating disk 2205, an annular groove 2206, a roller 2207 and a supporting column 2208.

[0040] The turntable 2205 is fixed to the upper part of the floating plate 10 through the support column 2208, the support frame 2204 is installed on the upper part of the turntable 2205, the sphere 2202 is rotatably set on the support frame 2204 through the rotating shaft 2203, and the sphere 2202 extends to the inner side of the groove 9, the oil-absorbing cotton 2201 is sleeved on the outer surface of the sphere 2202, and the oil-absorbing cotton 2201 and the groove 9 are in contact with each other.

[0041] An annular groove 2206 is provided on the circumferential position of the rotating disk 2205 , and a roller 2207 is rotatably provided inside the annular groove 2206 , and the roller 2207 and the support frame 2204 are in contact with the side wall of the groove 9 .

[0042] Since the groove 8 is arranged on the surface of the dust-free cloth 8, the dust-free cloth 8 is bound to be deformed when it is in constant contact with water. The deformation problem is specifically manifested in the groove 9. When the groove 9 is deformed, it brings inconvenience to cleaning.

[0043] To this end, the scraper assembly 22 includes oil-absorbing cotton 2201, a sphere 2202, a rotating shaft 2203, a support frame 2204, a turntable 2205, an annular groove 2206, a roller 2207, and a support column 2208. The turntable 2205 and the support frame 2204 are both located on the inner side of the groove 9. When the floating plate 10 is in motion, the sphere 2202 rotatingly arranged on the upper end of the support frame 2204 will contact with the bottom of the groove 9. At the same time, the outer side of the sphere 2202 is provided with oil-absorbing cotton 2201. When the oil-absorbing cotton 2201 contacts with the oily dust inside the groove 9, it will absorb the oil. Because the oil-absorbing cotton 2201 has the characteristics of oleophilicity and hydrophobicity, it means that they can effectively absorb oil substances, but have a repelling effect on water. In the whole process, not only the roller 2207 on the outer side of the turntable 2205 contacts with the inner wall of the groove 9, At the same time, both sides of the support frame 2204 are in contact with both sides of the groove 9, so that the deformation of the groove 9 can be effectively suppressed during the movement of the floating plate 10 by means of the contact between the roller 2207 and the support frame 2204 and the groove 9.

[0044] Example 5, reference Figure 5-6 The difference between this embodiment and Embodiment 1, Embodiment 2, Embodiment 3 and Embodiment 4 is that a shell 15 is installed on the outer side of the water inlet 12, and a rotating rod 13 is installed at the inner upper end of the water inlet 12. A plurality of fan blades 14 are distributed in a circular array on the outer side of the rotating rod 13. When water flows through the inside of the shell 15, the fan blades 14 are driven to rotate. A plurality of protrusions 26 are provided on the side of the fan blades 14 that contacts the water. The protrusions 26 are hemispherical, and a chamber 27 is hollowed out on one side of the protrusions 26.

[0045] A connecting plate 25 is hinged at one end of the floating plate 10, and the connecting plate 25 passes through the water inlet 12 and extends to the inner bottom of the outer shell 15. An elastic column 24 is installed on the connecting plate 25, and the fan blade 14 will contact and pass over the elastic column 24 when rotating.

[0046] The surface cleaning of the dust-free cloth 8 is achieved by contact between the dust-free cloth 8 and the water flow. When the contact occurs, the friction between the water flow and the dust-free cloth 8 is used to clean the oily dust on the surface of the dust-free cloth 8. However, this effect cannot be achieved when the water flow speed is slow.

[0047] To this end, a shell 15 is provided at the water inlet 12, and a rotatable fan blade 14 is provided inside the shell 15. When water enters the shell 15, it collides with the fan blade 14, and collides with the incoming water flow through the fan blade 14. Combined with the setting of the protrusion 26 and the chamber 27, the water encounters obstacles during the flow, thereby forming a turbulent flow phenomenon. At this time, the friction force increases during the contact between the water flow and the dust-free cloth 8, and the oily substance is carried away by means of the friction force generated between the two.

[0048] In order to make the movement of the floating plate 10 more regular, the fan blades 14 contact with the elastic columns 24 on the lower connecting plate 25 during rotation. During the contact process, the fan blades 14 exert external force on the elastic columns 24, so that the connecting plate 25 moves together with the floating plate 10 to the side close to the water inlet 12. When the fan blades 14 and the elastic columns 24 are separated from each other, the floating plate 10 and the connecting plate 25 return to their initial positions under the action of the elastic columns 20. This design can make the floating plate 10 move with a larger amplitude each time, thereby improving the cleaning effect of the upper scraper assembly 22 on the groove 9.

[0049] The working principle of the device is: The equipment is installed in the shaft of the mine. When the equipment is opened and operated, the blower bodies 1 on both sides are started. The blower bodies 1 suck in dust from the air inlet 16 and discharge it from the air outlet 17. At this time, the water tank 4 at the upper end is connected to the water supply equipment through the water pipe 5. The power switch of the water supply equipment is started, and water falls from the sprinkler nozzle 19, which just comes into contact with the dust below. During the contact process, the water and dust mix and fall down.

[0050] The dust in the mine contains a large amount of oily dust. If this dust falls directly, it will adhere to the inner wall of the mine and have an impact on the later operation of the mine.

[0051] To this end, a slot 7 is provided in the middle of the upper end of the watering box 6, and rotatable rollers 23 are provided on both sides of the slot 7, and the dust-free cloth 8 is sleeved between the outer sides of the two rollers 23. When the dust and water contact each other and fall on the dust-free cloth 8, the dust-free cloth 8 has a high-efficiency adsorption characteristic and can adsorb the oily dust. At the same time, the water can pass through the dust-free cloth 8 and flow back into the watering box 6. By turning on the power of the stepper motor 18, one of the rollers 23 is driven to roll. During the rolling, the position of the dust-free cloth 8 above the slot 7 keeps changing. The purpose of this design is that the water inside the watering box 6 is always in a flowing state. When the dust-free cloth 8 with oily dust adhered to it rotates to the inner side of the watering box 6, it will contact the flowing water source. In this way, the flowing water source is used to clean the oily dust adhered to the surface of the dust-free cloth 8, and the oily dust is taken away with the water flow, so that the dust-free cloth 8 can work for a longer period of time, and the dust-free cloth 8 can adhere to the oily dust with the highest efficiency each time it works.

[0052] If the outer surface of the dust-free cloth 8 is designed to be flat, the surface area of ​​the dust-free cloth 8 on which oily dust can adhere will be limited.

[0053] To this end, a plurality of grooves 9 are provided on the surface of the dust-free cloth 8. The grooves 9 are provided on the surface of the dust-free cloth 8, which can effectively increase the surface area of ​​the dust-free cloth 8. The bottom thereof is provided in an arc shape, and oily dust can be concentratedly collected on the inner side of the grooves 9.

[0054] Although the arrangement of the groove 9 can increase the area in contact with the oily dust, the dust is concentrated on the inner side of the groove 9 , which increases the difficulty of cleaning the inner side of the groove 9 .

[0055] To this end, there is flowing water inside the sprinkler box 6, and a float 10 is arranged on the liquid surface. When the two ends of the float 10 are connected to the inner walls of the sprinkler box 6 through elastic columns 20, when the partitions 21 at both ends of the float 10 are hit by the water flow, the float 10 will be driven to move inside the sprinkler box 6. At the same time, the two side walls of the float 10 and the two side walls inside the sprinkler box 6 fit each other. During the movement of the float 10, the elastic column 20 can play a certain limiting role. When the float 10 reciprocates at the lower end of the groove 8, the oily substance in the groove 8 is scraped off by the scraper assembly 22 at its upper end.

[0056] Since the groove 8 is arranged on the surface of the dust-free cloth 8, the dust-free cloth 8 is bound to be deformed when it is in constant contact with water. The deformation problem is specifically manifested in the groove 9. When the groove 9 is deformed, it brings inconvenience to cleaning.

[0057] To this end, the scraper assembly 22 includes oil-absorbing cotton 2201, a sphere 2202, a rotating shaft 2203, a support frame 2204, a turntable 2205, an annular groove 2206, a roller 2207, and a support column 2208. The turntable 2205 and the support frame 2204 are both located on the inner side of the groove 9. When the floating plate 10 is in motion, the sphere 2202 rotatingly arranged on the upper end of the support frame 2204 will contact with the bottom of the groove 9. At the same time, the outer side of the sphere 2202 is provided with oil-absorbing cotton 2201. When the oil-absorbing cotton 2201 contacts with the oily dust inside the groove 9, it will absorb the oil. Because the oil-absorbing cotton 2201 has the characteristics of oleophilicity and hydrophobicity, it means that they can effectively absorb oil substances, but have a repelling effect on water. In the whole process, not only the roller 2207 on the outer side of the turntable 2205 contacts with the inner wall of the groove 9, At the same time, both sides of the support frame 2204 are in contact with both sides of the groove 9, so that the deformation of the groove 9 can be effectively suppressed during the movement of the floating plate 10 by means of the contact between the roller 2207 and the support frame 2204 and the groove 9.

[0058] The surface cleaning of the dust-free cloth 8 is achieved by contact between the dust-free cloth 8 and the water flow. When the contact occurs, the friction between the water flow and the dust-free cloth 8 is used to clean the oily dust on the surface of the dust-free cloth 8. However, this effect cannot be achieved when the water flow speed is slow.

[0059] To this end, a shell 15 is provided at the water inlet 12, and a rotatable fan blade 14 is provided inside the shell 15. When water enters the shell 15, it collides with the fan blade 14, and collides with the incoming water flow through the fan blade 14. Combined with the setting of the protrusion 26 and the chamber 27, the water encounters obstacles during the flow, thereby forming a turbulent flow phenomenon. At this time, the friction force increases during the contact between the water flow and the dust-free cloth 8, and the oily substance is carried away by means of the friction force generated between the two.

[0060] In order to make the movement of the floating plate 10 more regular, the fan blades 14 contact with the elastic columns 24 on the lower connecting plate 25 during rotation. During the contact process, the fan blades 14 exert external force on the elastic columns 24, so that the connecting plate 25 moves together with the floating plate 10 to the side close to the water inlet 12. When the fan blades 14 and the elastic columns 24 are separated from each other, the floating plate 10 and the connecting plate 25 return to their initial positions under the action of the elastic columns 20. This design can make the floating plate 10 move with a larger amplitude each time, thereby improving the cleaning effect of the upper scraper assembly 22 on the groove 9.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
