Description

Technical Field

[0001] The present invention belongs to the technical field of dust suppression equipment, and particularly relates to a dust suppression device and method for railway transportation. Background Art

[0002] Railway transportation dust suppression devices are a series of equipment and technologies used to reduce or suppress dust generated during railway transportation, especially during the loading, unloading, and driving of bulk goods (such as coal, ore, etc.). These dusts not only pollute the environment but may also affect the health of residents along the railway and the safety of railway facilities.

[0003] In the prior art (patent application with publication number CN118142291B and patent name "A Dust Suppression Device and Method for Railway Transportation"), the spray head atomizes and sprays a dust removal emulsion onto the transportation carriage. The atomized dust removal emulsion adheres to the dust for dust suppression. When the dust removal emulsion is sprayed, it will flow from front to back along with the airflow. The flowing dust removal emulsion will drive the adhered dust into the interior of the diversion and filtration housing. The filtration and adsorption layer inside the diversion and filtration housing can effectively filter the dust removal emulsion and can effectively adsorb the dust removal emulsion. In the process of implementing this technical solution, it is found that there are at least the following problems in the prior art.

[0004] During the train's travel, especially in situations such as meeting another train or entering a tunnel, the action of wind and relative airflow will blow off the fine coal powder on the surface layer, further exacerbating the dust pollution problem. At the same time, when passing through curves, slopes, or track joints, vibrations will cause instability on the surface of the coal. The goods will rub against each other inside the carriage, the frictional force will increase, resulting in the fragmentation of the goods' surface, generating a large number of fine particles and dust. These dusts will not only affect air quality but also pose a threat to the health of residents along the railway. The existing devices cannot dynamically adjust the spray frequency and intensity according to the actual transportation situation. Summary of the Invention

[0015] Preferably, a method for dust suppression in railway transportation includes the following steps: S1: First, add an appropriate amount of environment-friendly dust suppressant inside the storage cylinder. Before loading, the sliding plate is initially located at the front end of the transport carriage. At this time, the fog cannon barrel and the annular sprayer are in a parallel state. The pressure pump sucks the dust suppressant in the storage cylinder into the drain pipe through the water suction pipe. The drain pipe discharges the dust suppressant into the fixed box and sprays it through the extension hose with the annular sprayer. At the same time, the shock-absorbing motor drives the impeller to rotate through the drive rod. Utilizing the strong wind force generated by the impeller, the wind enters through the large holes of the fog cannon barrel and exits through the small holes; S2: The servo motor starts. The servo motor drives the gear to move. The gear moves along the toothed plate towards the rear end of the transport carriage, so that the arc-shaped support frame moves on the I-shaped guide rail through the sliding plate. When the arc-shaped support frame drives the fog cannon barrel to move, first, the flipping slide rod moves from the front inclined groove of the guide groove plate to the straight groove. When the flipping slide rod is located in the straight groove of the guide groove plate, the flipping slide rod pulls the fog cannon barrel to flip around the installation shaft through the installation frame. After flipping, the fog cannon barrel is stuck on the limiting frame. After flipping, the annular sprayer is aligned with the transported goods, and then the annular sprayer sprays the dust suppressant on the goods; S3: When the sliding plate moves towards the rear end of the transport carriage, the sliding plate pulls out the plastic grille through the moving frame. The plastic grille moves along the surface of the goods. The tensioning roller is pushed by the spring return column to tension the plastic grille. When it moves to the rear end of the transport carriage, the flipping slide rod moves from the straight groove of the guide groove plate to the top of the inclined groove. The fog cannon barrel drives the downward pressure positioning plate to squeeze the plastic grille, making the plastic grille closely contact the goods; S4: When the fog cannon barrel moves to the rear end of the transport carriage, at this time, the small holes of the fog cannon barrel are aligned with the next transport carriage. The fog cannon barrel can spray the next carriage. The large holes of the fog cannon barrel generate suction. When the dust diffuses due to the influence of air flow during the flowing transportation of goods, the dust will hit the dust collection plate, and the dust will be sucked onto the dust-proof cloth bag through the flowing air and the suction generated by the fog cannon barrel.

[0016] A dust suppression device and method for railway transportation of the present invention: 1. For this dust suppression device for railway transportation, first, add an appropriate amount of environment-friendly dust suppressant inside the storage cylinder. Before loading, the sliding plate is initially located at the front end of the transport carriage. At this time, the fog cannon barrel and the annular sprayer are in a parallel state. The pressure pump sucks the dust suppressant in the storage cylinder into the drain pipe through the water suction pipe. The drain pipe discharges the dust suppressant into the fixed box and sprays it through the extension hose with the annular sprayer. The dust suppressant can increase the adhesion force between dust particles. The annular sprayer sprays continuously before loading the goods. At the same time, the shock-absorbing motor drives the impeller to rotate through the drive rod. Utilizing the strong wind force generated by the impeller, the wind enters through the large holes of the fog cannon barrel and exits through the small holes, pushing the atomized water mist to a long distance, enabling the water mist to float in the air over a large area and stay for a period of time, achieving the purpose of purifying the air and reducing dust.

[0017] 2. When the train is running, especially when meeting another train or entering a tunnel, under the action of wind and relative air flow, the fine pulverized coal on the surface layer will be blown off. The servo motor starts, and the servo motor drives the gear to move. The gear moves along the toothed plate towards the rear end of the transport carriage, so that the arc-shaped support frame moves on the I-shaped guide rail through the sliding plate. When the arc-shaped support frame drives the fog cannon barrel to move, first, the flipping slide rod moves from the front inclined slot of the guide groove plate to the straight slot. When the flipping slide rod is located in the straight slot of the guide groove plate, the flipping slide rod pulls the fog cannon barrel through the mounting frame to rotate 90 degrees around the mounting shaft. The rotated fog cannon barrel is stuck on the limiting frame. After rotation, the annular sprayer is aligned with the transported goods. Subsequently, the annular sprayer sprays the dust suppressant on the goods. The dust suppressant forms a covering layer on the surface of the goods, making it impossible to break away and form dust, thus reducing the possibility of its flying.

[0018] 3. At the same time, when the sliding plate moves towards the rear end of the transport carriage, the sliding plate pulls out the plastic grille through the moving frame. The plastic grille moves along the surface of the goods, and the tension roller is pushed by the spring return column to tension the plastic grille, so that the plastic grille is in close contact with the goods. When it moves to the rearmost end of the transport carriage, the flipping slide rod moves from the straight slot of the guide groove plate to the top of the inclined slot. Due to the limitation of the limiting frame on the fog cannon barrel, the fog cannon barrel can be made to be parallel to the transport carriage again. The fog cannon barrel drives the downward pressing positioning plate to squeeze the plastic grille, making the plastic grille in close contact with the goods. Through the physical covering of the plastic grille, it is prevented that the goods on the surface shake during transportation and cause dust to fly, reducing the dust pollution during railway transportation.

[0019] 4. When the fog cannon barrel moves to the rear end of the transport carriage, the small holes of the fog cannon barrel at this time are aligned with the next transport carriage. The fog cannon barrel can spray the next carriage. The large holes of the fog cannon barrel generate suction. When the goods are affected by air flow during flowing transportation and cause dust diffusion, the dust will hit the dust collecting plate, and the dust will be sucked onto the dust-proof cloth bag through the flowing air and the suction generated by the fog cannon barrel, preventing the dust from floating randomly. When the driving rod rotates, the driving rod drives the driving bevel gear to rotate. The driving bevel gear drives the driven bevel gear and the rotating rod to rotate. The rotating rod reciprocally pushes and pulls the reciprocating plate through the eccentric disk and the eccentric rod. The reciprocating plate drives the reciprocating seat and the reciprocating rod to reciprocate through the extension slide rod. The reciprocating rod drives the cleaning brush to clean the surface of the dust-proof cloth bag, preventing dust from accumulating and blocking the dust-proof cloth bag.

[0020] 5. The driving rod drives the extrusion arc plate to rotate. The extrusion arc plate pushes one end of the knocking rod to move. At this time, the other end of the knocking rod moves away from the dust-proof frame. When the extrusion arc plate does not contact the knocking rod, the reset spring resets and pushes the knocking rod to collide with the dust-proof frame. The dust-proof frame drives the dust-proof cloth bag to vibrate, so that the dust on the dust-proof cloth bag falls off. BRIEF DESCRIPTION OF THE DRAWINGS

Such a setting is that when the arc-shaped support frame 206 drives the fog cannon barrel 203 to move, the flipping slide bar 201 moves from the front inclined groove of the guiding groove plate 103 to the straight groove. When the flipping slide bar 201 is located in the straight groove of the guiding groove plate 103, the flipping slide bar 201 pulls the fog cannon barrel 203 through the mounting frame 202 to rotate 90° around the mounting shaft 204.

A cleaning brush 76 is fixedly connected to the outer wall of the reciprocating rod 74. The outer wall of the cleaning brush 76 is in contact with the outer surface of the dust-proof cloth bag 52. This is set so that the reciprocating plate 707 drives the reciprocating seat 73 and the reciprocating rod 74 to perform reciprocating motion through the extended sliding rod 72. The reciprocating rod 74 drives the cleaning brush 76 to clean the surface of the dust-proof cloth bag 52 to prevent dust accumulation from blocking the dust-proof cloth bag 52.

[0034] Such as Figure 14As shown, the dust-proof cloth bag 52 is used to filter dust in the air and prevent it from spreading into the air. However, during long-term use, a large amount of dust is likely to accumulate on the surface of the dust-proof cloth bag 52, resulting in the blockage of the cloth bag, reducing the filtration efficiency, and even completely failing. Therefore, it is necessary to regularly clean the dust on the surface of the dust-proof cloth bag 52 to ensure its normal operation. Inside the fog cannon barrel 203, a knocking mechanism 6 is provided. The knocking mechanism 6 includes a pressing arc plate 601 fixedly connected to the right end of the support frame 501.

The right end of the knocking rod 603 is in contact with the side wall of the dust-proof frame 51, and the left end of the knocking rod 603 is in contact with the side wall of the pressing arc plate 601. A return spring 604 is fixedly connected to the outer surface of the knocking rod 603. The end of the return spring 604 away from the knocking rod 603 is fixedly connected to the inner wall of the fog cannon barrel 203. This setting is to drive the rod 503 to drive the pressing arc plate 601 to rotate. The pressing arc plate 601 pushes one end of the knocking rod 603 to move. At this time, the other end of the knocking rod 603 moves away from the dust-proof frame 51. When the pressing arc plate 601 is not in contact with the knocking rod 603, the return spring 604 resets and pushes the knocking rod 603 to collide with the dust-proof frame 51.

[0035] As Figure 15 As shown, the working principle of a railway transportation dust suppression device and method: First, add an appropriate amount of environmentally friendly dust suppressant to the inside of the storage cylinder 404. Before loading, the sliding plate 207 is first located at the front end of the transportation carriage 101. At this time, the fog cannon barrel 203 and the annular sprayer 407 are in a parallel state. The pressure pump 401 sucks the dust suppressant in the storage cylinder 404 into the drain pipe 402 through the water suction pipe 403. The drain pipe 402 discharges the dust suppressant into the fixed box 405 and sprays it through the extension hose 406 with the annular sprayer 407. The dust suppressant can increase the adhesion force between dust particles. Before loading the goods, the annular sprayer 407 sprays continuously. At the same time, the shock-absorbing motor 502 drives the impeller 504 to rotate through the drive rod 503. Using the strong wind generated by the impeller 504, the wind enters from the large hole of the fog cannon barrel 203 and exits from the small hole, pushing the atomized water mist to a long distance, so that the water mist can float in the air over a large area and stay for a period of time, achieving the purpose of purifying the air and reducing dust; When the train is running, especially when meeting another train or entering a tunnel, under the action of wind force and relative air flow, the fine pulverized coal on the surface layer will be blown off. The servo motor 22 starts, and the servo motor 22 drives the gear 23 to move. The gear 23 moves along the toothed plate 24 towards the rear end of the transport carriage 101, so that the arc-shaped support frame 206 moves on the I-shaped guide rail 208 through the sliding plate 207. When the arc-shaped support frame 206 drives the fog cannon barrel 203 to move, first, the flipping slide bar 201 moves from the front inclined groove of the guide groove plate 103 to the straight groove. When the flipping slide bar 201 is located in the straight groove of the guide groove plate 103, the flipping slide bar 201 pulls the fog cannon barrel 203 to flip 90 degrees around the mounting shaft 204 through the mounting frame 202. The flipped fog cannon barrel 203 is stuck on the limiting frame 205. After flipping, the annular sprayer 407 is aligned with the transported goods. Subsequently, the annular sprayer 407 sprays the dust suppressant on the goods, and the dust suppressant forms a covering layer on the surface of the goods, making it impossible to break away and form dust, thereby reducing the possibility of its flying; During the 90° flipping of the fog cannon barrel 203, since the inclined groove plate 304 guides the plugging rod 303, the plugging rod 303 can move from the bottom end of the inclined groove plate 304 to the top end. When the plugging rod 303 is located at the top end of the inclined groove plate 304, the plugging rod 303 drives the plugging plate 302 to block the air outlet of the fog cannon barrel 203, preventing the wind generated by the impeller 504 from blowing up the fine pulverized coal on the surface layer; At the same time, when the sliding plate 207 moves towards the rear end of the transport carriage 101, the sliding plate 207 pulls out the plastic grille 802 through the moving frame 801. The plastic grille 802 moves along the surface of the goods, and the tension roller 803 is pushed by the spring return column 804 to tension the plastic grille 802, so that the plastic grille 802 is in close contact with the goods. When it moves to the rear end of the transport carriage 101, the flipping slide bar 201 moves from the straight groove of the guide groove plate 103 to the top of the inclined groove. Due to the restriction of the limiting frame 205 on the fog cannon barrel 203, the fog cannon barrel 203 can be re-parallel to the transport carriage 101. The fog cannon barrel 203 drives the downward pressing positioning plate 808 to squeeze the plastic grille 802, making the plastic grille 802 in close contact with the goods. Through the physical covering of the plastic grille 802, it prevents the goods on the surface from shaking during transportation and causing dust to fly, reducing the dust pollution during railway transportation; When the fog cannon barrel 203 moves to the rear end of the transport carriage 101, the small holes of the fog cannon barrel 203 at this time are aligned with the next transport carriage 101. The fog cannon barrel 203 can spray the next carriage. The large holes of the fog cannon barrel 203 generate suction. When the goods are affected by air flow during flowing transportation and cause dust diffusion, the dust will hit the dust collecting plate 711 and be sucked into the dust-proof cloth bag 52 by the flowing air and the suction generated by the fog cannon barrel 203, preventing the dust from floating randomly; When the driving rod 503 rotates, the driving rod 503 drives the driving bevel gear 701 to rotate. The driving bevel gear 701 drives the driven bevel gear 702 and the rotating rod 703 to rotate. The rotating rod 703 reciprocally pushes and pulls the reciprocating plate 707 through the eccentric disc 704 and the eccentric rod 705. The reciprocating plate 707 drives the reciprocating seat 73 and the reciprocating rod 74 to perform reciprocating motion through the extension slide rod 72. The reciprocating rod 74 drives the cleaning brush 76 to clean the surface of the dust-proof cloth bag 52, preventing dust accumulation from blocking the dust-proof cloth bag 52; The driving rod 503 drives the extrusion arc plate 601 to rotate. The extrusion arc plate 601 pushes one end of the knocking rod 603 to move. At this time, the other end of the knocking rod 603 moves away from the dust-proof frame 51. When the extrusion arc plate 601 does not contact the knocking rod 603, the reset spring 604 resets and pushes the knocking rod 603 to collide with the dust-proof frame 51. The dust-proof frame 51 drives the dust-proof cloth bag 52 to vibrate, so that the dust on the dust-proof cloth bag 52 falls off.
