Description

Technical Field

[0001] This invention relates to the field of residual coal cleaning technology, and in particular to a residual coal cleaning device for open-top train carriages. Background Technology

[0002] In the coal transportation sector, open-top trains are a common mode of transport. After the train arrives at its destination and unloads the coal, there is often a lot of residual coal left in the carriages. Currently, the main methods for cleaning up this residual coal are manual cleaning, air blowing cleaning, and water flushing cleaning.

[0003] During manual cleaning, workers must enter the car with shovels, brooms, and other tools to sweep up the remaining coal and remove it through the side door. This method is not only extremely labor-intensive, requiring workers to perform repetitive mechanical actions inside the car for extended periods, but also involves a harsh working environment. The car is cramped, poorly ventilated, and filled with dust. Prolonged exposure to such an environment greatly increases the risk of occupational diseases such as pneumoconiosis. Furthermore, manual cleaning is inefficient, often taking a considerable amount of time to clean a single car, making it difficult to meet the demands of rapid turnover transportation.

[0004] Air-blowing cleaning uses compressed air to blow out residual coal from the car body. However, this process generates a large amount of dust, which not only pollutes the surrounding environment but may also harm the health of nearby residents. Moreover, it does not meet the current stringent environmental protection requirements. Water-flushing cleaning uses high-pressure water jets to wash away residual coal from the car body. Although it can effectively remove residual coal, the subsequent treatment is more troublesome. It is necessary to build a sedimentation tank to treat the coal-water mixture. This not only increases the construction cost but also has strict requirements for the site, requiring a large area with good drainage conditions. In addition, neither air-blowing nor water-flushing can avoid the problem of incomplete removal of residual coal. Some residual coal will still stick to the corners or crevices of the car body. Summary of the Invention

[0005] In view of the above-mentioned problem that neither air blowing nor water flushing can completely remove residual coal, and that some residual coal will still stick to the corners or gaps of the carriage, this invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a coal cleaning device for open-top train carriages.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a coal cleaning device for open-top train carriages, comprising, The hopper is located on the upper side of the carriage to be cleaned; A cleaning mechanism, installed on the side wall and bottom of the silo, includes a movable component installed on the side wall of the silo, a rolling component installed on the movable component, and a brushing component installed at the bottom of the silo.

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Example Reference Figure 1 - Figure 8 According to an embodiment of the present invention, a coal cleaning device for open-top train carriages is provided. This device includes a hopper 1, which is located on the upper side of the carriage to be cleaned; a cleaning mechanism 2, which is installed on the side wall and the lower side of the hopper 1, including a moving part 21 installed on the side wall of the hopper 1, a rolling part 22 installed on the moving part 21, and a brushing part 23 installed at the bottom of the hopper 1, which completes the cleaning of residual coal in the carriage through the moving part 21, the rolling part 22 and the brushing part 23; and a suction mechanism 3, which is installed on the other side wall of the hopper 1, including a suction pipe 31 communicating with the hopper 1, a collector 32 installed on one side of the suction pipe 31, a lifting part 33 installed on the collector 32 and the suction pipe 31, and a high-pressure blower connecting pipe 34 communicating with one side of the hopper 1, which connects to a high-pressure blower to achieve a negative pressure state in the flow path from the suction pipe 31 to the hopper 1, and the movement of the lifting part 33 realizes dynamic adjustment of the height of the collected residual coal. By installing a cleaning mechanism 2 and a suction mechanism 3 on the hopper 1, the residual coal adhering to the car body is cleaned and the cleaned residual coal is sucked up, thus completing the cleaning and collection of residual coal in the car body.

[0033] Specifically, the moving part 21 includes a mounting frame 211 installed on one side wall of the hopper 1. The mounting frame 211 has a rectangular structure. Two first transverse hydraulic cylinders 212 are installed in the middle of the mounting frame 211. The two first transverse hydraulic cylinders 212 are installed in opposite directions and symmetrically. The moving ends of the two first transverse hydraulic cylinders 212 are respectively fixedly connected to the moving rods 213.

[0034] Furthermore, the movable component 21 also includes two first slide rails 214 mounted on the upper and lower sides of the mounting bracket 211, and two first pulley seats 215 slidably connected to the two first slide rails 214. The two first pulley seats 215 are fixedly connected to the two movable rods 213. The drive of the first transverse cylinder 212 drives the movable rods 213 to move, and the first pulley seats 215 move on the first slide rails 214 to provide stability for the movement.

[0035] Furthermore, the rolling element 22 includes a positioning seat 221 fixedly installed on the moving rod 213, a threaded brush 222 rotatably installed on the positioning seat 221, and a first motor 223 fixedly installed on the top of the threaded brush 222. The first motor 223 drives the threaded brush 222 to rotate, thereby cleaning the residual coal in the car body.

[0036] Furthermore, the brushing component 23 includes a limiting seat 231 fixedly installed on the moving rod 213, a second transverse hydraulic cylinder 232 fixedly installed at an angle on the limiting seat 231, an adjusting plate 238 rotatably connected to the moving end of the second transverse hydraulic cylinder 232, one side of the adjusting plate 238 rotatably connected to the limiting seat 231, and a first disc brush 233 rotatably connected to the adjusting plate 238, the first disc brush 233 having a bowl-shaped structure.

[0037] The second transverse cylinder 232 drives the adjusting plate 238 to adjust to a certain angle, which in turn drives the first disc brush 233 to adjust to a certain angle. The top of the first disc brush 233 is equipped with a motor that drives the first disc brush 233 to rotate. The first disc brush 233 moves with the movement of the moving rod 213 through the connection between the limiting seat 231 and the moving rod 213, thus expanding the brushing range of the first disc brush 233. Among them, the first brush 233 can rotate at a certain angle to increase the cleaning range.

[0038] Furthermore, the brushing component 23 also includes a lower base 234 fixedly installed at the bottom of the hopper 1. Two third transverse hydraulic cylinders 235 are fixedly installed on both sides of the lower base 234. The drive ends of the two third transverse hydraulic cylinders 235 are fixedly installed with second pulley seats 236. The second pulley seats 236 are slidably connected to the lower base 234. The second disc brush 237 is rotated and installed on the adjustment plate 238 by the second transverse hydraulic cylinder 232 and the adjustment plate 238, which are inclinedly installed on the second pulley seat 236. The second disc brush 237 and the first disc brush 233 have the same structure. The relative or opposite movement of the two second disc brushes 237 is achieved by driving the third transverse hydraulic cylinders 235, thereby increasing the brushing range.

[0039] Among them, according to the appendix Figure 8 The provided disc brush offers various movement trajectories to achieve cleaning of corners in the carriage, preventing material buildup.

[0040] Furthermore, the suction pipe 31 includes a suction port 311 and a discharge port 312. The suction port 311 and the discharge port 312 are located on the lower and upper sides of the suction pipe 31, respectively, and both are curved shovel structures, which makes the suction process undisturbed, with strong suction and smoother suction.

[0041] Furthermore, the collector 32 includes a third motor 321 mounted on both sides of its top. The drive ends of the two third motors 321 are respectively connected to two chains 322, and a left-handed propeller 323 and a right-handed propeller 324 are respectively connected to one side of the two chains 322.

[0042] Furthermore, the lifting component 33 includes cylinders 331 fixedly installed on both sides of the suction pipe 31. The driving ends of the two cylinders 331 are fixedly connected to the collector 32. The cylinders 331 are slidably connected to the sliding column 332, which is fixedly installed on the collector 32. In this way, when the cylinders 331 drive the collector 32 to rise or fall, the stability of the movement can be improved with the assistance of the sliding column 332.

[0043] During operation, this device can be moved as a whole by a lifting platform. First, the cleaning mechanism 2 starts to operate. The two opposing symmetrical first transverse hydraulic cylinders 212 on the mounting frame 211 on the side wall of the hopper 1 are driven synchronously. Their moving ends drive the corresponding moving rods 213 to move horizontally along the first slide rails 214 on the upper and lower sides of the mounting frame 211. The first pulley seat 215 on the moving rod 213 slides smoothly within the first slide rail 214 to ensure the stability of the movement. As the moving rod 213 moves, the threaded column brush 222 on its positioning seat 221 rotates at high speed under the drive of the first motor 223, penetrating into the inner wall and bottom gaps of the car body to loosen and stick the residual coal. At the same time, the limiting seat 2 on the moving rod 213... 31. The second transverse hydraulic cylinder 232, installed at an angle, pushes the adjusting plate 238 to adjust its angle around the rotation point of the limiting seat 231, so that the bowl-shaped first disc brush 233 on the adjusting plate 238 fits against the corners and curved areas of the carriage. The motor on top of the first disc brush 233 drives it to rotate for secondary fine brushing, and the first disc brush 233 moves with the moving rod 213 to expand the brushing range. The third transverse hydraulic cylinders 235 on both sides of the lower base 234 at the bottom of the hopper 1 drive the second pulley seat 236 to slide along the lower base 234, causing the second disc brush 237 installed through the second transverse hydraulic cylinder 232 and the adjusting plate 238 to move relative to or towards each other. The combination of multiple movement trajectories of the disc brushes cleans the corners of the carriage to avoid material accumulation. The second brush 237 has the same structure as the first brush 233 and rotates synchronously to achieve comprehensive cleaning. Simultaneously with the activation of the cleaning mechanism 2, the suction mechanism 3 operates synchronously. The high-pressure blower connecting pipe 34 on one side of the hopper 1 is opened, creating negative pressure along the flow path from the suction pipe 31 to the hopper 1. The suction port 311 of the lower curved shovel structure of the suction pipe 31 is close to the bottom of the carriage, smoothly sucking in the loose residual coal. The undisturbed design of the discharge port 312 of the upper curved shovel structure allows the residual coal to be smoothly transported to the collector 32. The third motors 321 on both sides of the top of the collector 32 drive the left-hand screw 323 and right-hand screw 324 to rotate via chains 322, collecting and guiding the sucked residual coal. The suction pipe 31... The cylinders 331 on both sides drive the collector 32 to rise and fall according to the height of the remaining coal accumulation. The sliding column 332 assists in improving the stability of the collector 32's movement. The cleaning mechanism 2 and the suction mechanism 3 interact on the hopper 1. The threaded column brush 222 works with the disc brush to achieve thorough cleaning without dead angles, solving the problems of corner accumulation and remaining coal adhesion. The disc brush can be adjusted in angle and position to achieve full coverage. The curved shovel structure suction and discharge port works in conjunction with stable negative pressure, ensuring turbulent suction and preventing the remaining coal from scattering and causing secondary pollution. The screw propeller works in conjunction to achieve rapid collection of remaining coal, reducing the risk of clogging in the hopper 1. Multiple components are equipped with slide rails, pulley seats, and other auxiliary guides to reduce failure and maintenance costs. The lifting component 33 stably adjusts the height of the suction port 311 to ensure suction effect.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
