Description

Technical Field

[0001] This utility model belongs to the field of dust suppression spraying devices, and in particular relates to a dust suppression spraying device for railway coal transportation. Background Technology

[0002] Currently, some railway sections are equipped with a dust suppression spraying device for railway coal transportation. This device consists of a spraying actuator (spray pipe, multiple sets of atomizing nozzles, and a high-pressure pump set), a media supply system, a support and transmission structure (support columns and a lifting mechanism), a detection and sensing unit, and a control center. Its main function is to spray dust suppressant onto the surface of coal inside the train car, forming a solidified film that blocks dust diffusion and achieves dust suppression. However, existing railway coal dust suppression spraying systems face a technical challenge: the dust suppressant solution has a certain viscosity, and after spraying, it easily solidifies and remains in the pipes and nozzles, causing equipment blockage. Currently, a "flushing method" is used for pipe maintenance, switching to a cleaning fluid after spraying to clean the system. However, this solution has significant drawbacks: because there is no collection device below the nozzles when spraying the cleaning fluid, the cleaning fluid is sprayed directly onto the track, resulting in resource waste. Furthermore, in winter, the cleaning fluid sprayed on the track is prone to freezing, increasing the risk to train operation. Utility Model Content

[0003] The purpose of this invention is to provide a dust suppression spraying device for railway coal transportation, which can collect and recover the cleaning liquid sprayed at the nozzles when flushing the pipeline, thus avoiding resource waste.

[0004] The aforementioned dust suppression spraying device for railway coal transportation includes a spraying equipment body. A collection hopper is hinged to the outer wall of the spraying pipe of the spraying equipment body. A driving component for driving the swing angle of the collection hopper is provided on the spraying pipe. A drainage hose communicating with the inside of the collection hopper is connected to the collection hopper. A fixing component for fixing the drainage hose to the water supply pipe of the spraying equipment body is provided.

[0005] Furthermore, the drive assembly includes a worm gear and a worm that mesh with each other. A mounting platform is fixed on the spray pipe, and two parallel and aligned mounting plates are fixed on the mounting platform. The worm is rotatably mounted between the two mounting plates. A motor is mounted on the mounting platform, and one end of the worm is connected to the output end of the motor. A rotating shaft aligned with the axis of the hinge point is horizontally fixed on the collection hopper, and the worm gear is fitted onto the rotating shaft.

[0006] Furthermore, a protective cover for shielding and protecting the motor, worm gear, and worm is detachably fixed on the mounting platform.

[0007] Furthermore, the fixing component includes a connecting plate, with clamps fixed at both ends of the connecting plate. The two clamps are respectively fitted onto the water supply pipe and the drainage hose of the spraying equipment body.

[0008] Furthermore, a friction pad is provided on the inner wall of the clamp.

[0009] Furthermore, an installation groove is provided around the opening of the collection hopper, and a sealing strip for sealing the gap between the collection hopper and the spray pipe is engaged in the installation groove.

[0010] Furthermore, the cross-section of the collection hopper has a "U" shape.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] Before spraying the cleaning fluid, the drive assembly swings the collection bucket until it is directly below the spray pipe. When the cleaning fluid is sprayed, it falls into the collection bucket, which collects the fluid and drains it into an external collection container for storage via a drain hose. This process recovers the cleaning fluid, preventing it from being discharged onto the track and avoiding resource waste. Afterward, the drive assembly swings the collection bucket in the opposite direction, positioning it to one side of the spray pipe to prevent it from obstructing the nozzle when the dust suppressant is sprayed.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0021] Example

[0022] This embodiment describes a dust suppression spraying device for railway coal transportation, such as... Figure 1 , Figure 4 and Figure 6 As shown, the spraying equipment includes the main body of the spraying equipment, which is an existing device. It consists of a spraying actuator (spray pipe, multiple sets of atomizing nozzles, water supply pipe and high pressure pump set), a media supply system, a support and transmission structure (support column and lifting mechanism), a detection and sensing unit, a control center, etc. It is mainly used to spray dust suppressant on the surface of coal inside the vehicle, so that a solid film is formed on the surface of the coal to block the spread of dust and achieve the effect of dust suppression.

[0023] A collection hopper 2 is hinged along the length of the outer wall of the spray pipe 1 of the spraying equipment body; such as Figure 1 , Figure 3 and Figure 5 As shown, one side of the collection hopper 2's opening is hinged to the side wall of the spray pipe 1 via a pivot. The opening on one side of the hopper has spaced openings. Two spaced hinge blocks are fixed to the outer wall of the spray pipe 1 by screws. A pivot is horizontally fixed inside each opening, and the hinge blocks have through holes for inserting the pivot. Alternatively, the collection hopper 2 can also be hinged to the outer wall of the spray pipe 1 via a hinge. Figure 5 As shown, when the collection hopper 2 swings downward and its opening is in contact with the lower wall of the spray pipe 1, the collection hopper 2 is located directly below the spray pipe 1. Therefore, when the atomizing nozzle on the spray pipe 1 sprays the cleaning liquid downward, the collection hopper 2 can collect the cleaning liquid. Before the atomizing nozzle on the spray pipe 1 sprays the dust suppressant downward, the collection hopper 2 swings forward to move to one side of the spray pipe 1, so as to avoid the collection hopper 2 blocking the atomizing nozzle.

[0024] A mounting groove is provided around the opening of the collecting hopper 2, and a sealing strip 11 for sealing the gap between the collecting hopper 2 and the spray pipe 1 is engaged within the mounting groove; Figure 6 As shown, when the collecting hopper 2 swings to directly below the spray pipe 1, and the opening of the collecting hopper 2 is in contact with the outer wall of the spray pipe 1, the sealing strip 11 will be squeezed and adhered to the outer wall of the spray pipe 1, thereby sealing the gap between the opening of the collecting hopper 2 and the outer wall of the spray pipe 1 through the sealing strip 11, preventing the cleaning fluid in the collecting hopper 2 from leaking.

[0025] To elaborate further, such as Figure 1 , Figure 4 and Figure 6 As shown, in this embodiment, the preferred embodiment includes a meshing worm gear 7 and a worm 9, and a mounting platform 4 is fixed on the spray pipe 1; in this embodiment, the right end of the spray pipe 1 is fixed with the mounting platform 4; two parallel and aligned mounting plates 8 are fixed on the mounting platform 4; as shown Figure 4 As shown, two mounting plates 8 are fixed perpendicular to the side wall of the mounting platform 4 facing away from the water pipe; the worm gear 9 is rotatably mounted between the two mounting plates 8; as shown Figure 4 As shown, the two mounting plates 8 have mounting holes for independently mounting the two ends of the worm gear 9. The worm gear 9 is parallel to the side wall of the mounting plate 8 facing away from the water pipe, allowing the worm gear 9 to rotate freely. A motor 10 is mounted on the mounting platform 4, and the motor 10 is mounted on the side wall of the mounting plate 8 facing away from the water pipe by bolts and mounting brackets. One end of the worm gear 9 is connected to the output end of the motor 10, and the end of the worm gear 9 facing the motor 10 is connected to the output end of the motor 10 through a coupling. The forward and reverse rotation of the motor drives the worm gear 9 to rotate forward and reverse. A rotating shaft aligned with the axis of the hinge point is horizontally fixed on the collecting hopper 2, and the worm wheel 7 is mounted on the rotating shaft. Figure 2 As shown, the rotating shaft is horizontally fixed on the right side wall of the collecting hopper 2, and the axis of the rotating shaft is aligned with the hinge point between the collecting hopper 2 and the spray pipe 1 (e.g., Figure 2 and Figure 6 As shown, the rotating shaft is aligned with the pivot axis. Therefore, when the worm gear 9 drives the worm wheel 7 to rotate, the worm wheel 7 drives the rotating shaft to rotate, which in turn drives the collection bucket 2 to swing around the hinge point. This technical solution constitutes a drive assembly for driving the swing angle of the collection bucket 2. Of course, the drive assembly can also use a servo motor. The right end of the spray pipe 1 is fixed with a mounting platform 4, and the servo motor is mounted on the mounting platform 4. A rotating shaft aligned with the hinge point axis is horizontally fixed on the collection bucket 2, and the rotating shaft is connected to the output end of the servo motor. In position control mode, if there is no new instruction input, the servo motor will continuously fine-tune its position through a closed-loop feedback system to keep the motor stationary at the specified coordinates. The servo motor can also achieve physical self-locking by adding an electromagnetic brake (holding brake).

[0026] The mounting platform 4 is detachably fixed with a protective cover 3 for shielding and protecting the motor 10, worm gear 7, and worm 9; such as Figure 4 , Figure 5 and Figure 6 As shown, the protective cover 3 is fixed to the side wall of the mounting platform 4 facing away from the water pipe by screws. The protective cover 3 covers the motor 10, worm gear 7 and worm 9 to prevent the internal components and equipment from being impacted, contaminated and exposed to sun and rain.

[0027] The collection hopper 2 is connected to a drain hose 6 that communicates with its interior; such as Figure 1 and Figure 6As shown, the drain hose 6 is connected to the side wall of the collection hopper 2. One end of the drain hose 6 is connected to the inside of the collection hopper 2, and the other end can be connected to an external collection container. Thus, the cleaning liquid collected in the collection hopper 2 is transported to the external collection container for storage through the drain hose 6, thereby completing the recycling of the cleaning liquid and avoiding resource waste. The cross-section of the collection hopper 2 is U-shaped to facilitate the collection of the cleaning liquid sprayed downward by the atomizing nozzle. The U-shaped structure also makes it easier to concentrate the cleaning liquid in the middle area of ​​the bottom of the collection hopper 2, allowing the cleaning liquid to converge at the port of the drain hose 6, which is conducive to the faster discharge of the cleaning liquid in the collection hopper 2.

[0028] To elaborate further, such as Figure 1 , Figure 3 and Figure 6 As shown, this embodiment preferably includes a connecting plate 5, with clamps fixed to both ends of the connecting plate 5. The two clamps are respectively fitted onto the water supply pipe and drain hose 6 of the spraying equipment body. In this embodiment, the clamps have the same structure as existing products. The two clamps are fitted onto the water supply pipe and drain hose 6 of the spraying equipment body. By rotating the screws on the two clamps, the clamps are fixed to the water supply pipe and drain hose 6 of the spraying equipment body. The connecting plate 5 connects the water supply pipe and drain hose 6 of the spraying equipment body. Because the water supply pipe of the spraying equipment body is made of metal, it can support the drain hose 6, preventing the drain hose 6 from hanging too long downwards and avoiding damage to the drain hose 6 due to friction between the train carriage and the drain hose 6. Of course, when fixing the drain hose 6, if... Figure 1 As shown, a flexible end of sufficient length for the drain hose 6 needs to be reserved to ensure that the collection hopper 2 is not restricted by the drain hose 6 when swinging; the fixing point of the drain hose 6 is lower than the connection point between the drain hose 6 and the collection hopper 2 to ensure smooth discharge of the cleaning fluid; friction pads are provided on the inner wall of the clamp, which can protect the water supply pipe and drain hose 6 of the spraying equipment body, preventing the clamp from damaging the water supply pipe and drain hose 6 of the spraying equipment body, and the friction pads can increase the friction between the water supply pipe and drain hose 6 of the spraying equipment body to prevent the clamp from moving; this solution constitutes a fixing component for fixing the drain hose 6 to the water supply pipe; of course, the fixing component can also be a strap, with both ends of the strap tied to the water supply pipe and drain hose 6 of the spraying equipment body, thereby connecting the water supply pipe and drain hose 6 of the spraying equipment body, of course, a flexible end of sufficient length for the drain hose 6 needs to be reserved to ensure that the collection hopper 2 is not restricted by the drain hose 6 when swinging.

[0029] In actual use, before spraying the cleaning fluid, the motor 10 is started. The motor 10 drives the worm 9 to rotate, the worm 9 drives the worm wheel 7 to rotate, and the worm wheel 7 drives the rotating shaft to rotate. In turn, the rotating shaft drives the collection bucket 2 to swing around the hinge point until the collection bucket 2 swings directly below the spray pipe 1. After that, when the cleaning fluid is sprayed to clean the pipeline and nozzles of the dust suppression spraying device for railway coal transportation, the sprayed cleaning fluid will fall into the collection bucket 2. The collection bucket 2 collects the cleaning fluid and discharges it into an external collection container for storage through the drain hose 6, thereby completing the recycling of the cleaning fluid and preventing the cleaning fluid from being discharged onto the track and avoiding resource waste. After that, the motor 10 is controlled to rotate in the opposite direction, thereby driving the collection bucket 2 to swing in the opposite direction, so that the collection bucket 2 swings to the front of the spray pipe 1 to prevent the collection bucket 2 from obstructing the nozzle when the dust suppressant is sprayed.
