Description

Technical Field

[0001] This application relates to the field of coal mine equipment technology, and in particular to a rotary annular spraying device. Background Technology

[0002] During coal mining operations, a large amount of dust is generated and dispersed throughout the working environment due to factors such as mechanical and manual construction. This dust not only severely deteriorates the working environment but also poses a significant threat to environmental quality and human health. Therefore, taking effective dust suppression measures during mining operations is crucial to improving the working environment and reducing the negative impacts of dust. Among these measures, using spray equipment to spray water mist around the working environment has become a common and important method for dust suppression.

[0003] Current coal mine spraying equipment completes water spraying by setting up a spraying mechanism. By controlling the operation of the electric push rod, the sliding rod slides in the chute, thereby adjusting the angle of the adjusting plate. Under the action of the adjusting plate, the spraying direction of the spray pipe in the spraying equipment is adjusted.

[0004] However, current spraying equipment can only spray at a fixed angle at a fixed location during operation. Since dust activity during coal mining is irregular, this fixed-angle spraying method results in poor dust suppression. Furthermore, the spraying equipment only has an angle adjustment function and cannot allow for reciprocating oscillation adjustments. During operation, it can only spray at a fixed angle, which is insufficient to meet the complex and ever-changing dust suppression needs during coal mining. Utility Model Content

Detailed Implementation

[0049] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0050] Because some technologies only allow spraying at a fixed angle to a fixed position, and cannot perform multi-angle spraying, this application provides a rotary annular spraying device to solve this technical problem. The structure of each part of the rotary annular spraying device is described below:

[0051] like Figure 2 The diagram shown is a structural schematic of the rotary annular spray device in this application.

[0052] This application provides a rotary annular spray device, comprising:

[0053] Installation box 1, wherein a water storage tank 11 is provided inside the installation box 1; the water storage tank 11 is used to store spray water for spraying.

[0054] A water pumping device 2 is provided, one end of which is connected to the water storage tank 11 and the other end of which is connected to the main pipe body 3. The water pumping device 2 is used to pump water from the water storage tank 11 into the main pipe body 3. The main pipe body 3 is a hollow structure. Several first spray heads 31 are provided on the outside of the main pipe body 3, and the first spray heads 31 are connected to the inside of the main pipe body 3. The water pumping device 2 is used to pump spray water from the water storage tank 11 into the main pipe body 3. The main pipe body 3 is a hollow structure, and the spray water is sprayed outward from the first spray heads 31 through the through hole between the main pipe body 3 and the first spray heads 31.

[0055] like Figure 1 and Figure 3 The figure shown is a cross-sectional view of the rotary annular spray device in this application.

[0056] The pumping device 2 includes:

[0057] A water pump 21 is provided, with its pumping end connected to the water storage tank 11 and its outlet end connected to a transfer pipe 22. The transfer pipe 22 is located on the top of the water storage tank 11. One end of the transfer pipe 22 is connected to a transmission pipe 23, and the other end of the transmission pipe 23 is connected to the main body 3. The water pump 21 is used to pump the spray water from the water storage tank 11 to the transfer pipe 22, which then transmits the water to the transmission pipe 23, and finally into the main body 3.

[0058] It is worth noting that the transmission pipe 23 and the adapter pipe 22 are connected by a bearing, allowing the transmission pipe 23 to be rotatably connected to the adapter pipe 22, while the adapter pipe 22 is fixed inside the mounting box 1. The connection method between the transmission pipe 23 and the adapter pipe 22 is not limited here.

[0059] The first rotating device 4 is disposed inside the mounting box 1, such as Figure 4 As shown, the first rotating device 4 is rotatably connected to the transmission pipe 23, located at the top of the water storage tank 11. The first rotating device 4 causes the main pipe 3 to rotate, thereby causing several first spray heads 31 located on the outside of the main pipe 3 to spray outwards. Driven by the first rotating device 4, the first spray heads 31 spray to various corners on the outside, increasing the spraying area of ​​the spraying equipment.

[0060] In this embodiment, the first rotating device 4 includes:

[0061] An electric motor 41 is mounted on top of the water storage tank 11. The output end of the electric motor 41 is connected to a first gear 42. The first gear 42 meshes with a second gear 43, which is fitted onto the transmission pipe 23. When the spray function is activated, the electric motor 41 starts, and the first gear 42 rotatably connects to the second gear 43, causing the transmission pipe 23 to rotate. The electric motor 41 provides power to the first gear 42, causing it to rotate, which in turn drives the second gear 43 to rotate. The transmission pipe 23 is fitted inside the second gear 43, thus rotating under the influence of the second gear 43.

[0062] In this embodiment, a retainer 231 is connected to the outside of the transmission pipe 23; the retainer 231 is connected to a water collection hood 232, which is connected to the mounting box 1; the retainer 231 is disposed inside the water collection hood 232; a water collection trough 233 is provided at the connection between the water collection hood 232 and the mounting box 1, the water collection trough 233 is connected to one end of a return pipe 234, and the other end of the return pipe 234 is connected to the water storage tank 11. The water collection hood 232 is used to collect the spray water falling on the top of the mounting box 1 and return it to the water storage tank 11 through the return pipe 234, thereby saving the consumption of spray water.

[0063] In this embodiment, a filter screen 235 is provided inside the water collection tank 233.

[0064] Specifically, a water collection trough 233 is provided at the bottom of the water collection cover 232, and a filter screen 235 is provided inside the water collection trough 233. A fixing ring is provided at the bottom of the filter screen 235 and the fixing ring is fixed inside the water collection trough 233. The water collection trough 233 is connected to one end of the return pipe 234, and the other end of the return pipe 234 is connected to the inside of the water storage tank 11. In use, when the spray water after being sprayed by the first spray head 31 drips back into the water collection cover 232 under the action of the water collection cover 232, the filter screen 235 can filter the dust in the spray water. Then the spray water flows back into the water storage tank 11 through the filter screen 235.

[0065] In this embodiment, a beveled ring 32 is provided on the side of the water collection hood 232 away from the mounting box 1; a bevel gear 33 is provided on the side of the first spray head 31 near the transmission pipe 23, and the bevel gear 33 meshes with the beveled ring 32, such as... Figure 6 As shown.

[0066] When the spray function is activated, the motor 41 starts, and the bevel gear 33 is rotatably connected to the bevel gear ring 32, causing the first spray head 31 to rotate. By starting the motor 41 and rotating the bevel gear 33 within the bevel gear ring 32, the first spray head 31 revolves, further increasing its spray area. It is understood that the first spray head 31 has several spray nozzles with gaps between them. If it does not rotate when spraying outwards, there will be spray gaps (areas not covered by the spray water). The arrangement of the bevel gear 33 rotating within the bevel gear ring 32 avoids these spray gaps in the first spray head 31.

[0067] In this embodiment, a liquid filling pipe 111 is provided on the top of the water storage tank 11; the liquid filling pipe 111 is used to add auxiliary agents into the water storage tank 11, and the auxiliary agents are used to increase the dust reduction effect of the spray water.

[0068] A stirring shaft 12 is installed inside the water storage tank 11. One end of the stirring shaft 12 is connected to the bottom of the water storage tank 11, and the other end is fitted with a third gear 13. Several stirring plates 121 are arranged on the outside of the stirring shaft 12. The stirring shaft 12 is rotatably connected to a second rotating device 5 through the third gear 13. The second rotating device 5 is installed inside the mounting box 1. By driving the stirring shaft 12 to rotate through the second rotating device 5, the spray water in the water storage tank 11 can be stirred, thereby ensuring that the auxiliary agent inside the water storage tank 11 is stirred evenly.

[0069] like Figure 8 The diagram shown is a structural schematic of the second rotating device in this application.

[0070] In this embodiment, the second rotating device 5 includes:

[0071] The fourth gear 51 meshes with the third gear 13; the fourth gear 51 is connected to the first rotating shaft 52, one end of the first rotating shaft 52 is connected to the fourth gear 51, and the other end extends to the outside of the water storage tank 11, and the other end of the first rotating shaft 52 is provided with a first friction plate 53.

[0072] An electric actuator 54 is mounted on the top of the water storage tank 11, and its power end is connected to a rotating plate 55. An internal spline shaft 56 is connected inside the rotating plate 55. A second friction plate 57 is located at one end of the internal spline shaft 56 near the water storage tank 11, and the second friction plate 57 is located in the same vertical direction as the first friction plate 53. An external spline shaft 58 is connected inside the internal spline shaft 56, and one end of the external spline shaft 58 is connected to a fifth gear 59. The fifth gear 59 is located on the top of the mounting box 1 and meshes with the second gear. Wheel 43; wherein, the electric push rod 54 is provided with a first state position and a second state position; when the electric push rod 54 is in the first state position, there is a gap between the first friction plate 53 and the second friction plate 57; when the electric push rod 54 is in the second state position, the first friction plate 53 abuts against the second friction plate 57; wherein, after the stirring function is turned on, the motor 41 starts, and the electric push rod 54 is in the second state position; the fourth gear 51 is rotatably connected to the third gear 13 under the drive of the fifth gear 59, causing the stirring shaft 12 to rotate.

[0073] In this embodiment, a liquid filling pipe 111 is connected to the upper end of the water storage tank 11. A stirring shaft 12 is rotatably installed inside the water storage tank 11. Several stirring plates 121 are fixedly installed on the stirring shaft 12. A sealing box is rotatably installed at one end of the stirring shaft 12. The sealing box is fixedly installed inside the upper end of the water storage tank 11 to prevent the third gear 13 and the fourth gear 51 installed inside it from being soaked by the sprayed water. A third gear 13 is fixedly installed at one end of the stirring shaft 12. A fourth gear 51 is meshed on the third gear 13. The fourth gear 51 is rotatably installed inside the sealing box. A fixed shaft is fixed on one side of the rotating shaft of the fourth gear 51. One end of the fixed shaft extends to the outside of the water storage tank 11. A second friction plate 57 is fixedly provided at one end, and a first friction plate 53 is provided above the second friction plate 57. The first friction plate 53 is fixedly provided at one end of the inner spline shaft 56. An outer spline shaft 58 is slidably provided inside the inner spline shaft 56. The outer spline shaft 58 is fixedly provided on the rotating shaft at one end of the fifth gear 59. The fifth gear 59 is meshed with the second gear 43. A rotating frame is fixed at the bottom end of the water collection cover 232. The fifth gear 59 is provided in the rotating frame to prevent the fifth gear 59 from being damaged by the spray water. The inner spline shaft 56 is rotatably provided in the rotating plate 55. The rotating plate 55 is fixed on the output end of the electric push rod 54. The electric push rod 54 is fixed on the top of the water storage tank 11.

[0074] Specifically, when it is necessary to add auxiliary agents to the water storage tank 11 to increase the dust reduction effect, auxiliary agents and water are added to the water storage tank 11 through the liquid addition pipe 111. When spraying, the electric push rod 54 is activated. The output end of the electric push rod 54 drives the inner spline shaft 56 through the rotating plate 55, so that the first friction plate 53 and the second friction plate 57 are in close friction. As a result, when the transmission pipe 23 rotates, it drives the stirring shaft 12 to rotate through the third gear 13 and the fifth gear 59, so that the several stirring plates 121 on the stirring shaft 12 can stir the auxiliary agents in the water storage tank 11.

[0075] In this embodiment, a spray pipe 34 is connected to the side of the main body 3 away from the mounting box 1, and a plurality of second spray heads 341 are provided on the side of the spray pipe 34 away from the main body 3, such as... Figure 5 As shown. The second spray head 341 can spray upwards, thereby further increasing the spray area of ​​the spraying device.

[0076] like Figure 7 The diagram shown is a structural schematic of the spray head assembly in this application.

[0077] In this embodiment, a plurality of spray head assemblies 6 are connected to the side of the main body 3 away from the mounting box 1.

[0078] The spray head assembly 6 includes:

[0079] A fixing plate 61 is disposed opposite to the main body 3 on the side away from the mounting box 1; a third spray head 62 is connected to the fixing plate 61 by bolts 63; the third spray head 62 is connected to the main body 3 by a hose 64, which is disposed in the gap between the fixing plates 61; wherein, the spray angle of the third spray head 62 is adjusted by the bolts 63.

[0080] In this embodiment, the spray head assembly 6 includes a third spray head 62. A plurality of third spray heads 62 are arranged in a circular array above the main body 3. Each third spray head 62 has a symmetrically provided fixing plate 61 at its bottom end. The fixing plate 61 is fixedly provided on the upper end of the main body 3. The input end of each third spray head 62 is connected to a flexible hose 64. The other end of each flexible hose 64 is connected to the main body 3. In use, the spray angles of the first spray head 31 and the second spray head 341 are fixed. Therefore, when it is necessary to spray other angles, the tilt angle of the third spray head 62 can be adjusted by bolts 63. At the same time, the tilt angles of the plurality of third spray heads 62 can be different. When the main body 3 rotates, the third spray heads 62 with different tilt angles can spray different positions.

[0081] In this embodiment, an installation ring 236 is provided on the inner side of the water collection cover 232, and the installation ring 236 is provided with a plurality of insertion holes 2361.

[0082] The device also includes:

[0083] The baffle 7 is snapped into the insertion hole 2361, thereby connecting the baffle 7 to the mounting ring 236. A collection box 8 is fixedly provided on one side of the mounting box 1 for convenient storage of the baffle 7 during use.

[0084] In this embodiment, an installation ring 236 is fixedly provided at one end of the inner side of the water collection cover 232. The installation ring 236 has a plurality of insertion holes 2361 at equal intervals. The baffle 7 is installed in the insertion holes 2361. The baffle 7 is arc-shaped. In use, when it is necessary to spray a specific location, the baffle 7 is installed at the location where spraying is not required. When the first spray head 31 and the second spray head 341 are rotated to the position of the baffle 7, the baffle 7 blocks the spray water at the spraying location of the first spray head 31 and the second spray head 341, so that the spray water flows back into the water storage tank 11.

[0085] This application provides a rotary annular spraying device. A second spray head 341 and a third spray head 62 are installed at the upper end of the main pipe body 3. Several first spray heads 31 are installed on the outer side of the main pipe body 3. The main pipe body 3 is rotated by a motor 41, which expands the spraying range of the spray pipe. The first spray heads 31 rotate on their own axis while revolving around the central axis, increasing the spraying effect. The several third spray heads 62 are adjustable in tilt, allowing different tilt angles to spray different positions, enabling continuous multi-angle spraying. A water collection hood 23 is also included. 2. The water collection hood 232 is connected to the water storage tank 11 through the return pipe 234, so that when the spray water at the spray point of the spray pipe drips back into the water collection hood 232, it is filtered by the filter screen 235, which facilitates the recycling of the spray water. By setting the stirring shaft 12 inside the water storage tank 11, it is easy to mix the spray water inside the water storage tank 11. By setting the mounting ring 236 at one end of the inner side of the water collection hood 232, when it is necessary to spray at a specific angle, the spray point can be blocked by adding a baffle 7, so that spraying can be performed at a set position, thereby increasing the practicality of the rotary ring spray equipment.
