Description

Technical Field

[0001] This invention relates to the field of dust suppression technology, specifically to a self-rotating dust suppression fog cannon device. Background Technology

[0002] Dust is generated during mining, construction, and demolition, polluting the environment and harming health. Fog cannons were developed to address these problems. The principle of a fog cannon is to atomize water using a specific method, and then use a long-range fan to propel the atomized water mist particles to the area where dust suppression is needed. These water mist particles are extremely fine, reaching the micron level, and can decompose and dilute the concentration of particulate matter in the air, effectively breaking down airborne pollutants and dust.

[0003] Traditional fog cannons can disperse water jets under high-pressure airflow, but the fixed nozzles result in uneven water distribution, which affects both atomization and cleaning efficiency. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, this invention provides a self-rotating dust suppression fog cannon device; this invention improves the uniformity of water flow distribution through a rotating water spray cylinder design.

[0005] The present invention adopts the following technical solution: a self-rotating dust suppression fog cannon device, including a cylinder, and a fan is installed at the rear end of the cylinder;

[0006] Also includes:

[0007] A turntable is supported under the cylinder; the turntable is mounted on a sanitation vehicle.

[0008] The support assembly is installed at the front end of the cylinder.

[0009] The spray assembly is mounted on the support assembly;

[0010] A water supply pipe passes through the side wall of the cylinder and connects to the spray assembly;

[0011] The spray assembly includes a rotating cylinder rotatably mounted on the support assembly; the rotating cylinder is coaxial with the cylinder body, the rear end of the rotating cylinder is connected to the water supply pipe through a rotary joint, and a water spray tube is vertically fixed at the front end of the rotating cylinder; the water spray tube is connected to the rotating cylinder, and the water spray tube has evenly distributed spray holes; impellers are rotatably mounted at both ends of the water spray tube, and the two impellers are arranged in a centrally symmetrical manner.

[0012] Furthermore, a mesh plate is fixed to the rear end of the cylinder.

[0013] An ear plate seat is fixed on the turntable, and the two sides of the cylinder are respectively hinged to the two sides of the ear plate seat; an adjusting rod is respectively hinged to the two sides of the middle part of the cylinder, and the other end of the adjusting rod is hinged to the turntable.

[0014] A handle is fixed to the turntable.

[0015] The support assembly includes a front support ring and a rear support ring arranged front to back, and the front support ring and the rear support ring are coaxial with the cylinder body; the periphery of the front support ring is fixedly connected to the inner wall of the rotating cylinder by a plurality of evenly distributed long secondary supports, and the periphery of the rear support ring is fixedly connected to the corresponding long secondary supports by a plurality of evenly distributed short secondary supports.

[0016] The rotating drum is rotatably mounted in the front support ring via bearings;

[0017] The fixed part of the rotary joint is fixedly installed in the rear support ring.

[0018] The front end of the cylinder is constricted, and an outer sleeve is fixed to the outside of the front end of the cylinder. An annular gap with a sealed rear end and an open front end is formed between the outer sleeve and the front end of the cylinder. A ring of evenly distributed connecting holes is opened on the inner wall of the cylinder, and the connecting holes connect the annular gap with the inside of the cylinder.

[0019] The impellers at both ends of the water spray cylinder are located in front of the annular gap and are axially opposite to the annular gap in the cylinder body.

[0020] The impeller does not extend beyond the front end of the outer sleeve.

[0021] A pull rod is inserted through the shaft of the rotating drum, and caps are fitted at both ends of the pull rod. The caps are fastened to both ends of the rotating drum. Nuts are threadedly connected to both ends of the pull rod, and the nuts press the caps tightly against the ends of the rotating drum.

[0022] The impeller is rotatably mounted on the end of the pull rod via a bearing; two spiral strips arranged around the water spray cylinder are fixed on the inner side of the impeller, and the other ends of the two spiral strips are fixedly connected to a rotating ring sleeved on the water spray cylinder.

[0023] The spray nozzles on the water spray tube are located at positions corresponding to the spiral strips.

[0024] The beneficial effects of this invention are:

[0025] The design of the spray assembly's rotating drum and rotary joint allows for a continuous water supply during rotation, while the nozzle arrangement of the spray tube ensures uniform water distribution. The high-pressure airflow provided by the fan not only propels the spray but also enhances the airflow pressure driving the impeller's rotation through the design of the annular gap, enabling the spray tube to rotate evenly and further improving the uniformity of the spray.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1:

[0044] like Figures 1 to 3 As shown, this invention provides a self-rotating dust suppression fog cannon device. The cylinder 1 is supported on a turntable 3, which is mounted on a sanitation vehicle. A fan 2 is installed at the rear end of the cylinder 1, providing high-pressure airflow to the front end of the cylinder 1. A mesh plate 11 is fixed to the rear end of the cylinder 1 to prevent large debris from entering.

[0045] Combination Figures 1 to 4 As shown, the support assembly 4 is fixed at the front end of the cylinder 1 and is used to install the spray assembly 5;

[0046] The support assembly 4 includes a front support ring 41 and a rear support ring 42 arranged at the axis of the cylinder. Six evenly distributed long auxiliary supports 43 are welded around the periphery of the front support ring 41. The outer ends of the long auxiliary supports 43 are inclined backward and welded to the inner wall of the rotating cylinder 51. The front support ring 41 is used to install the rotating cylinder 51 in the spray assembly 5. Three evenly distributed short auxiliary supports 44 are welded around the periphery of the rear support ring 42. The outer ends of the short auxiliary supports 44 are inclined forward and welded to the corresponding long auxiliary supports 43. The rear support ring 42 is used to install the rotary joint 52 in the spray assembly 5. A water supply pipe 6 passes through the side wall of the cylinder 1 and connects to the fixed part of the rotary joint 52. The water supply pipe 6 is tied to one of the long auxiliary supports 43 and the short auxiliary supports 44 with steel wire.

[0047] Combination Figures 1 to 6 As shown, the spray assembly 5 is mounted on the support assembly 4 and is used to spray the water delivered by the water supply pipe 6 onto the front port of the cylinder 1.

[0048] The spray assembly 5 includes a rotating cylinder 51 and a rotary joint 52 arranged at the axis of the cylinder body. The middle part of the rotating cylinder 51 is rotatably mounted in the front support ring 41 via a bearing. The rotating part of the rotary joint 52 is fixed to the rear end of the rotating cylinder 51, and the fixed part of the rotary joint 52 is fixed in the rear support ring 42. A water spray tube 53 is vertically fixed to the front end of the rotating cylinder 51. The rotating cylinder 51 and the water spray tube 53 are in a "T" shape and are interconnected. Both ends of the water spray tube 53 are closed, and evenly distributed spray holes 531 are opened on the surface of the water spray tube 53. The spray holes 531 are inclined forward. During operation, water flows sequentially through the water supply pipe 6, the rotary joint 52, the rotating cylinder 51, and the water spray tube 53, and then is sprayed out from the spray holes 531. Under the action of the high-pressure airflow provided by the fan 2, a spray is formed and sprayed out from the front end of the cylinder body 1.

[0049] Impellers 54 are rotatably mounted at both ends of the water spray tube 53, and the two impellers 54 are arranged in a centrally symmetrical manner. Under the action of high-pressure airflow, the impellers 54 at both ends can drive the water spray tube 53 to rotate, making the water flow distributed more evenly.

[0050] The front end of the cylinder 1 is constricted to increase airflow pressure. An outer sleeve 12 is welded to the outside of the front end of the cylinder 1, with its front end extending beyond the front end of the cylinder 1. An annular gap 13 is formed between the outer sleeve 12 and the front end of the cylinder 1, with the rear end of the annular gap 13 sealed and the front end open. A ring of evenly distributed connecting holes 14 is formed on the inner wall of the cylinder 1, connecting the annular gap 13 to the interior of the cylinder 1, allowing some airflow to enter the annular gap 13 through the connecting holes 14. An impeller 54 is positioned in front of the annular gap 13; the impeller 54 is axially opposite the annular gap 13 in the cylinder 1 and does not extend beyond the front end of the outer sleeve 12. During operation, the airflow within the annular gap 13 is more concentrated and interference from other airflows is avoided, thus making it easier to drive the impeller 54, causing the water spray nozzle 53 to rotate.

[0051] Example 2:

[0052] Based on the above embodiment one, combined with Figures 3 to 6 As shown, a pull rod 55 passes through the shaft of the rotating drum 51, with a gap between the pull rod 55 and the rotating drum 51 to allow water to flow through. A cap 56 is fitted onto each end of the pull rod 55, and the caps 56 are fastened to both ends of the rotating drum 51 to achieve a seal at the ends of the rotating drum 51. External threads are provided at both ends of the pull rod 55, and nuts 57 are installed thereon; by tightening the nuts 57, the caps 56 are pressed tightly against the ends of the rotating drum 51.

[0053] The impeller 54 is rotatably mounted on the end of the tie rod 55 via a bearing. In this embodiment, two spiral strips 58 are fixed to the inner surface of the impeller 54, and a rotating ring 59 is fixed to the other end of the two spiral strips 58, so that the impeller 54, spiral strips 58, and rotating ring 59 form a whole. The rotating ring 59 is sleeved on the water spray tube 53 and is clearance-fitted with the water spray tube 53; the spiral strips 58 are wound around the water spray tube 53 and are also clearance-fitted with the water spray tube 53. The spray holes 531 on the water spray tube 53 are opened at positions corresponding to the radial direction of the spiral strips 58. During operation, the rotating impeller 54 drives the spiral strips 58 and the rotating ring 59. The rotating spiral strips 58 cut the water flow sprayed from the spray holes 531, interrupting and dispersing the water flow, making the sprayed water flow more evenly distributed.

[0054] Example 3:

[0055] Based on the above embodiments one or two, combined with Figure 1 , Figure 2 As shown, turntable 3 is used to adjust the pitch angle and circumferential position of cylinder 1;

[0056] The ear plate seat 31 is welded to the turntable 3. Two symmetrical rear hinge plates are located on both sides of the rear of the cylinder 1, and these rear hinge plates are hinged to the ear plates on both sides of the ear plate seat 31. Two symmetrical front hinge plates are located on both sides of the front of the cylinder 1. The upper end of the adjusting rod 32 is hinged to the front hinge plate, and the lower end of the adjusting rod 32 is hinged to the ear plate seat 31. A small shaft is fixed in the middle of the adjusting rod 32 to facilitate rotation; the pitch angle of the cylinder 1 can be adjusted by rotating the adjusting rod 32. The turntable 3 is rotatably mounted on the sanitation vehicle, and the turntable 3 is positioned with the sanitation vehicle using a tightening bolt or pin. A handle 33 is fixed to one side of the turntable 3 to facilitate rotation and achieve circumferential adjustment of the cylinder 1.

[0057] Working principle:

[0058] After the sanitation vehicle arrives at the designated location, the pitch angle of the cylinder 1 is adjusted by rotating the adjusting rod 32, and the circumferential position of the cylinder 1 is adjusted by rotating the turntable 3.

[0059] Then, start fan 2 to supply water to water pipe 6;

[0060] The water flows through the water supply pipe 6, the rotary joint 52, the rotating drum 51, and the spray pipe 53 in sequence, and then sprays out from the spray hole 531;

[0061] Fan 2 provides high-pressure airflow to the front end of cylinder 1 and sprays it out from the front end of cylinder 1; the water flow sprayed from nozzle 531 forms a spray under the action of high-pressure airflow and is sprayed out from the front end of cylinder 1.

[0062] In addition, some airflow enters the annular gap 13 between the outer sleeve 12 and the front end of the cylinder 1 through the connecting hole 14, and is ejected from the front end of the outer sleeve 12, driving the impellers 54 on both sides to rotate. Under the action of the impellers 54, the water spray cylinder 53 rotates around the rotating cylinder 51 as the axis, so that the water flow is evenly distributed. At the same time, the impeller 54 drives the spiral strip 58 to rotate, cutting the water flow ejected from the spray hole 531, cutting off and dispersing the water flow, so that the sprayed water flow is more evenly distributed.

[0063] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
