Description

Technical Field

[0001] This utility model relates to the field of dust suppression in blasting, and in particular to a water mist spraying device for dust suppression in blasting. Background Technology

[0002] Dust suppression during blasting refers to technical measures that suppress the diffusion of dust generated during blasting operations by spraying water mist, foam, or chemical dust suppressants, thereby reducing air pollution and occupational health hazards. Its core principle is to use the weight of water mist particles to promote the rapid settling of suspended particles. Common methods include high-pressure spraying, water curtain covering, pre-wetting of rock mass, or foam sealing.

[0003] During blasting operations, a large amount of high-concentration dust is generated due to the violent impact. The fog field produced by the spraying device has a limited coverage area and uneven distribution, making it difficult to suppress dust in the entire working space. As a result, a large amount of respirable dust is suspended in the working environment for a long time. At the same time, in the dense dust environment, dust will adhere to the surface of the nozzle. Over time, this will cause the nozzle to become clogged, affecting the normal use of the device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water mist spraying device for dust suppression during blasting, thereby increasing the dust suppression range and improving the ease of cleaning the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A water mist spraying device for dust suppression during blasting includes:

[0007] A bottom moving disc for bottom support, wherein a water storage tank is fixedly connected to the top center of the bottom moving disc, a support transmission sleeve is fixedly connected to the top center of the water storage tank, a rotating conveyor disc is rotatably connected to the upper outer side of the support transmission sleeve, and multiple spray frames are fixedly connected to the outer circumference of the rotating conveyor disc. A bidirectional water inlet assembly is installed at the top of the water storage tank, and a rotating traction assembly is installed inside the support transmission sleeve to achieve the diffusion of the spray range.

[0008] Connecting arc plates are used to connect multiple spray frames to each other. Each connecting arc plate has an installation slot inside. A dust blocking component is installed on the outside of the connecting arc plate to block and clean dust in high-density environments.

[0009] Furthermore, the dust blocking assembly includes a connecting column nested inside the mounting slot, a dust blocking ring fixedly connected to the outer side of the connecting column, the inner side of the dust blocking ring fitting against the outer side of the spray frame, a fixing ring threadedly connected to the outer side of the connecting column, and multiple external discharge filter ports opened around the outer circumference of the dust blocking ring.

[0010] Furthermore, the bidirectional water inlet assembly includes a water supply pipe fixed on the right side of the water storage tank, a transmission arc pipe fixedly connected to the top of the water supply pipe, water inlet swivel pipes fixedly connected to both the front and rear sides of the bottom of the supporting transmission sleeve, the outer sides of the water inlet swivel pipes being fixedly connected to the inner sides of the transmission arc pipes respectively, and a high-pressure water pump fixedly connected to the top right side of the water storage tank outside the water supply pipe.

[0011] Furthermore, the rotary traction assembly includes a rotary support rod whose top end is located inside the support transmission sleeve and rotates. A traction roller is fixedly connected to the lower outer side of the rotary support rod. Multiple traction plates are fixedly connected to the outer circumference of the traction roller. The top end of the rotary support rod is fixedly connected to the bottom inner end of the rotary conveyor disc.

[0012] Furthermore, the outer circumference of the rotating conveyor disc is provided with multiple external discharge slots, the outer sides of which are located on the inner side of the spray frame.

[0013] Furthermore, a water inlet pipe is fixedly connected to the top left side of the water storage tank to allow water to be added to the tank.

[0014] Furthermore, soft rubber mounting pads are fixedly connected to the inner side of each fixing ring.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, water is introduced horizontally into the lower part of the support transmission sleeve through the water inlet and vortex pipe, thereby contacting the traction plate, rotating the traction roller, causing the rotating support rod to rotate, and the rotating conveyor disc to rotate as well. This allows water to be discharged outward through the spray frame, increasing the dust suppression range and improving the dust suppression effect of the device.

[0017] In this invention, a dustproof blocking ring blocks dense dust on the outside of the spray frame, preventing dust from directly entering the interior. Multiple fixing rings are rotated and adjusted to detach the dustproof blocking ring from the inside of the connecting arc plate, thereby lifting and removing the dustproof blocking ring upwards. This improves the ease of cleaning the device and prevents dust from entering and causing blockages. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3This utility model provides an embodiment of a water mist spraying device for dust suppression during blasting, comprising: a bottom movable disk 1 for bottom support; a water storage tank 2 fixedly connected to the top center of the bottom movable disk 1; a support transmission sleeve 5 fixedly connected to the top center of the water storage tank 2; a rotating conveyor disk 11 rotatably connected to the upper outer side of the support transmission sleeve 5; multiple spray frames 10 fixedly connected to the outer circumference of the rotating conveyor disk 11; a bidirectional water inlet assembly installed at the top of the water storage tank 2; and a rotating traction assembly installed inside the support transmission sleeve 5 to achieve diffusion of the spray range. The bidirectional water inlet assembly includes a water delivery pipe 14 fixedly located on the right side of the water storage tank 2, a transmission arc pipe 6 fixedly connected to the top of the water delivery pipe 14, and water inlets fixedly connected to both the front and rear sides of the bottom of the support transmission sleeve 5. The outer side of the water inlet swirl pipe 4 is fixedly connected to the inner side of the transmission arc pipe 6. The top right side of the water storage tank 2 is fixedly connected to the outside of the water supply pipe 14. The rotating traction assembly includes a rotating support rod 13 that rotates inside the support transmission sleeve 5 at the top of the water storage tank 2. A traction roller 21 is fixedly connected to the lower outer side of the rotating support rod 13. Multiple traction plates 16 are fixedly connected to the outer circumference of the traction roller 21. The top of the rotating support rod 13 is fixedly connected to the inner bottom of the rotating conveyor plate 11. Multiple external discharge slots 15 are opened around the outer circumference of the rotating conveyor plate 11. The outer sides of the external discharge slots 15 are located inside the spray frame 10. A water inlet pipe 3 is fixedly connected to the top left side of the water storage tank 2 to realize the addition of water flow inside the water storage tank 2.

[0027] After water is injected into the water storage tank 2 through the water inlet pipe 3, the high-pressure water pump 7 is started to transport the water upward through the water delivery pipe 14 to the transmission arc pipe 6. Subsequently, the water is diverted to the water inlet and swirl pipes 4 on both sides. The two water streams simultaneously generate horizontal impact force inward, which directly acts on the cross surface of the traction plate 16, driving the traction roller 21 to rotate, which in turn drives the rotating support rod 13 to rotate. At the same time, the water accumulates in the support transmission sleeve 5 and is transported upward into the rotating conveyor plate 11. Under the combined action of centrifugal force and water pressure, the water is sprayed outward at high speed through the spray frame 10, forming a wide-angle atomization effect, which significantly expands the dust suppression coverage area, thereby greatly improving the dust suppression efficiency and overall performance of the device.

[0028] Reference Figure 1 , Figure 4 and Figure 5A connecting arc plate 12 is used to connect multiple spray frames 10 to each other. The interior of the connecting arc plate 12 is provided with an installation slot 17. A dust blocking component is installed on the outside of the connecting arc plate 12 to block and clean dust in high-density environments. The dust blocking component includes a connecting column 18 nested inside the installation slot 17. A dustproof blocking ring 8 is fixedly connected to the outside of the connecting column 18. The inside of the dustproof blocking ring 8 is attached to the outside of the spray frame 10. A fixing ring 20 is threadedly connected to the outside of the connecting column 18. Multiple external discharge filter ports 9 are opened around the outside of the dustproof blocking ring 8. A soft rubber mounting pad 19 is fixedly connected to the inside of the fixing ring 20.

[0029] During dust suppression operations, the dustproof blocking ring 8 effectively prevents external dust from entering, ensuring a stable dust suppression process. After the area dust suppression is completed, it can be quickly disassembled by rotating multiple fixing rings 20. The inner thread of the fixing ring 20 engages with the outer thread of the connecting column 18. Rotating in the opposite direction will separate the connecting arc plate 12 from the connecting column 18. At this time, applying an upward pulling force to the connecting column 18 will allow the dustproof blocking ring 8 to be removed from the outside of the spray frame 10 as a whole. This modular design significantly improves the ease of maintenance of the device, thoroughly removes accumulated dust, and effectively prevents clogging caused by dust accumulation, greatly extending the service life of the equipment.

[0030] Working principle: Water is added into the water storage tank 2 through the water inlet pipe 3. At this time, the high-pressure water pump 7 is started, and the water inside the water storage tank 2 is drawn upward through the water delivery pipe 14, thus entering the interior of the transmission arc pipe 6. The transmission arc pipe 6 draws the water to the water inlet swirl pipes 4 on both sides. The water inlet swirl pipes 4 on both sides simultaneously generate a horizontal impact force inward. The water directly contacts the horizontal surface of the traction plate 16, thereby generating a rotational force on the traction roller 21, which in turn rotates the rotating support rod 13 itself. The water accumulates inside the support transmission sleeve 5, drawing the water upward, thus transmitting the water to the interior of the rotating conveyor plate 11. In the spray frame 10, water is sprayed outwards by the centrifugal force of the rotating conveyor plate 11 and the water pressure, thus expanding the dust suppression range. During the dust suppression process, external dust is blocked by the dustproof blocking ring 8, ensuring the stability of the dust suppression operation. After the dust in the area is suppressed, the multiple fixing rings 20 are rotated respectively. The inner thread of the fixing ring 20 contacts the outer thread of the connecting column 18, causing it to disengage from the inner side of the connecting arc plate 12. An upward lifting force is applied to the connecting column 18, thereby disengaging the dustproof blocking ring 8 from the outside of the spray frame 10, thus cleaning the external dust.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
