Description

Technical Field

[0001] This utility model relates to the field of mine safety and environmental protection technology, and specifically discloses a rotating three-dimensional spraying device. Background Technology

[0002] Coal mining faces and roadways generate large amounts of coal dust and particulate matter during coal production, seriously endangering the health of workers and deteriorating the working environment. Existing dust suppression measures mostly employ fixed spray devices, which have a single spray direction and limited coverage, failing to effectively capture and settle coal dust that dynamically diffuses with airflow. In particular:

[0003] The spray has a large blind spot and cannot achieve full coverage in three-dimensional space;

[0004] The fixed spray angle makes it difficult to cope with the uncertainty and instability of dust flow;

[0005] It has a slow dust suppression response, a long dust diffusion distance, and low dust suppression efficiency.

[0006] Therefore, there is an urgent need for a device that can achieve dynamic spraying in three-dimensional space, with no blind spots and high efficiency in dust reduction, in order to solve the above-mentioned technical problems. Utility Model Content

[0007] This invention proposes a rotating three-dimensional spraying device that uses a wind-water linkage to drive the rotating spraying mechanism, achieving dynamic dust suppression in three-dimensional space without blind spots, significantly improving dust suppression efficiency and speed, completely eliminating spray blind spots, and requiring no electricity, being safe and reliable, having a simple structure, and being inexpensive.

[0008] This invention is implemented as follows: a rotating three-dimensional spraying device, comprising:

[0009] Two fixed frames in a circular shape;

[0010] A fixing plate is coaxially disposed in the middle of the two fixing frames, and the fixing plate has a through hole in the middle;

[0011] Multiple fixing rods are arranged in a circular array to connect the fixing plate to the inner wall of the fixing frame;

[0012] The main tube is inserted and fixed in the through holes of the two fixing plates;

[0013] Multiple spray pipes are arranged in a parallel circular array on the outer wall of the main pipe, and their two ends are fixedly connected to the two fixed frames.

[0014] Multiple nozzles are evenly spaced on the outer wall of the spray pipe;

[0015] Multiple branch pipes connect the main pipe and the spray pipe for conveying the air-water mixture fluid;

[0016] Two rolling bearings are respectively sleeved on the outer wall of the main pipe, located on the outside of the two fixed frames;

[0017] The blade drive wheel is fixed to one of the rolling bearings on the side facing the fixed frame and welded to the main tube;

[0018] The lifting frame is U-shaped, with its two ends connected to the two rolling bearings, and is used to suspend the device from the roof of the tunnel.

[0019] Rotate the sealing cap, which is located at the open end of the main pipe, to seal and connect the water inlet pipe and the air inlet pipe;

[0020] The water inlet valve and the air inlet valve are respectively installed on the water inlet pipe and the air inlet pipe;

[0021] A three-way valve is located on the intake pipe, and one end of it is connected to the blade drive wheel through the second intake pipe.

[0022] As a preferred embodiment of the rotating three-dimensional spraying device of this utility model, the nozzle is a hemispherical nozzle with eyelets, and the spherical surface is provided with multiple water spray needle holes at different angles for spraying out three-dimensional spherical water mist.

[0023] As a preferred embodiment of the rotating three-dimensional spraying device of this utility model, the fixed frame is made of steel bars with a diameter of 5mm welded into a circular frame with a diameter of 1000mm, and is welded to the fixed plate in the middle by 6 fixed rods to form an integral structure.

[0024] As a preferred embodiment of the rotating three-dimensional spraying device of this utility model, the branch pipes are provided in total with 6 pipes, with each pair forming a group, which are connected to three groups of spray pipes respectively to achieve uniform distribution of air and water fluids.

[0026] As a preferred embodiment of the rotating three-dimensional spraying device of this utility model, the blade drive wheel has uniformly distributed blades inside, which are welded and fixed to the main pipe, and the outer shell is welded and fixed to the outside of the rolling bearing. The blades are driven to rotate by compressed air, which in turn drives the entire device to rotate.

[0027] As a preferred embodiment of the rotating three-dimensional spraying device of this utility model, the upper part of the lifting frame is fixed to the lifting anchor rod of the tunnel roof, and the lower part is connected to the two rolling bearings for suspending and stabilizing the entire device.

[0045] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0046] Please see Figure 1-9 A rotating three-dimensional spray device, comprising:

[0047] Two fixed frames in a circular shape 1;

[0048] The fixing plates 2 are coaxially disposed in the middle of the two fixing frames 1, and the fixing plates 2 are provided with through holes in the middle;

[0049] Multiple fixing rods 3 are arranged in a circular array to connect the fixing plate 2 to the inner wall of the fixing frame 1;

[0050] The main pipe 4 is inserted and fixed in the through holes of the two fixing plates 2;

[0051] Multiple spray pipes 5 are arranged in a parallel circular array on the outer wall of the main pipe 4, and their two ends are fixedly connected to two fixed frames 1.

[0052] Multiple nozzles 6 are evenly spaced on the outer wall of the spray pipe 5;

[0053] Multiple branch pipes 7 connect the main pipe 4 and the spray pipe 5 for conveying the air-water mixture fluid;

[0054] Two rolling bearings 8 are respectively fitted onto the outer wall of the main pipe 4, located on the outside of the two fixed frames 1;

[0055] The blade drive wheel 9 is fixed to one of the rolling bearings 8 on the side facing the fixed frame 1 and welded to the main tube 4;

[0056] The lifting frame 10 is U-shaped, with its two ends connected to two rolling bearings 8, and is used to suspend the device on the roof of the tunnel.

[0057] Rotate the sealing cap 11, which is located at the open end of the main pipe 4, to seal and connect the water inlet pipe 12 and the air inlet pipe 13;

[0058] Water inlet valve 14 and air inlet valve 15 are respectively installed on the water inlet pipe 12 and air inlet pipe 13;

[0059] A three-way valve 16 is located on the intake pipe 13, and one end of it is connected to the blade drive wheel 9 through the second intake pipe 17.

[0060] In this embodiment: After the operator opens the water inlet valve 14 and air inlet valve 15 connected to the mine pipeline, pressurized water enters the rotating sealing cover 11 through the water inlet pipe 12 and compressed air enters the air inlet pipe 13, and then flows into the main pipe 4; the air-water mixture is evenly distributed in the main pipe 4 through six branch pipes 7 into three sets of annularly symmetrically distributed spray pipes 5, and finally sprayed out by multiple hemispherical multi-angle nozzles 6 set on the spray pipes 5 to form a fine water mist; at the same time, part of the compressed air enters the blade drive wheel 9 chamber after being diverted through the three-way valve 16, which drives the blades welded to the main pipe 4 to rotate, thereby driving the main pipe 4 and the two circular fixed frames 1 fixed at both ends by the fixed plate 2 and the fixed rod 3 to rotate together; the entire spray system smoothly rotates 360° horizontally around the main shaft under the support of the lifting frame 10 through the rolling bearing 8, so that the sprayed water mist forms a continuously moving, interwoven and covered three-dimensional water curtain network, thereby achieving no dead angles and dynamic and efficient dust reduction in the three-dimensional space of the coal mine roadway.

[0061] As a technical optimization of this utility model, the nozzle 6 is a hemispherical nozzle with eyelets. The spherical surface is provided with multiple water spray needle holes at different angles for spraying three-dimensional spherical water mist.

[0062] In this embodiment, by defining the nozzle 6 as a "hemispherical structure with pinholes at different angles", it is ensured that the water mist can be sprayed out in a three-dimensional spherical form, which expands the coverage angle of the single-point spray and enhances the probability of collision with dust. This is the key to achieving efficient dust suppression.

[0063] As a technical optimization of this utility model, the fixed frame 1 is made of steel bars with a diameter of 5mm welded into a circular frame with a diameter of 1000mm, and is welded to the fixed plate 2 in the middle by 6 fixed rods 3 to form an integral structure.

[0064] In this embodiment, by specifically defining the materials, dimensions, and connection methods of the fixed frame 1 and the fixed rod 3, the entire rotary spraying system is ensured to have sufficient mechanical strength and stability in high-speed rotation and complex downhole environments, preventing structural deformation or failure.

[0065] As a technical optimization of this utility model, the branch pipe 7 has a total of 6 pipes, with each pair forming a group, which are connected to the three groups of spray pipes 5 respectively, so as to achieve uniform distribution of air and water fluid.

[0066] In this embodiment, by limiting the specific number and connection method of the branch pipes 7, it is ensured that the air-water mixture can be evenly and synchronously distributed from the main pipe 4 to the three sets of spray pipes 5, so that all nozzles 6 have consistent pressure, uniform spray, and no dead zones in flow.

[0067] As a technical optimization of this utility model, the water inlet pipe 12 and the air inlet pipe 13 are made of high-pressure rubber hoses with a diameter of 12mm, and quick plugs are provided at the connection points.

[0068] In this embodiment, the use of high-pressure hoses and quick-connect plugs enables the device to connect quickly, reliably, and with good sealing to the existing water and gas supply lines in the mine, facilitating installation, disassembly, and maintenance, and meeting the needs of rapid relocation underground.

[0069] As a technical optimization of this utility model, the blade drive wheel 9 has uniformly distributed blades inside, which are welded and fixed to the main pipe 4. The outer shell is welded and fixed to the outside of the rolling bearing 8. The blades are driven to rotate by compressed air, which drives the entire device to rotate.

[0070] In this embodiment, the existing power source of mine compressed air is used to drive the blades, thereby converting fluid energy into mechanical rotation. This achieves safe and reliable self-driven rotation without the need for electricity, which is the key to "automatic" and "three-dimensional" spraying.

[0071] As a technical optimization of this utility model, the upper part of the lifting frame 10 is fixed to the lifting anchor rod of the roadway roof, and the lower part is connected to two rolling bearings 8 for suspending and stabilizing the entire device.

[0072] In this embodiment, the cooperation between the lifting frame 10 and the rolling bearing 8 not only achieves the function of stably suspending the entire device on the roof of the roadway, but also provides a supporting foundation for the smooth rotation of the entire system, ensuring stability during operation.

[0073] Working principle and usage process of this utility model:

[0074] The operator opens the water inlet valve 14 and the air inlet valve 15; mine pressurized water enters the main pipe 4 through the water inlet pipe 12 and compressed air enters the main pipe 4 through the air inlet pipe 13 and the rotating sealing cover 11; the air-water mixture is evenly distributed in the main pipe 4 to the three sets of annularly arranged spray pipes 5 through the branch pipes 7; the mixture is finally sprayed out from multiple hemispherical nozzles 6 evenly distributed on the spray pipes 5, forming a fine water mist; at the same time, part of the compressed air is diverted through the three-way valve 16 and enters the chamber of the blade drive wheel 9 through the second air inlet pipe 17, pushing the blades inside; the blade drive wheel 9 rotates, driving the main pipe 4 welded to it to rotate together, thereby driving the two fixed frames 1 fixed to the main pipe 4 and all the spray pipes 5 and nozzles 6 to rotate 360° horizontally around the main axis; during the rotation of the device, the water mist it sprays forms a continuously moving and interwoven three-dimensional water curtain network, which provides full coverage and dynamic continuous dust suppression in the roadway space.
