Description

Technical Field

[0001] The present invention relates to the technical field of bulk loaders, in particular to a train particle bulk loader. Background Art

[0002] In the modern railway freight system, the loading and unloading of granular materials such as cement clinker, coal, ore, and grain is subject to the dual stringent requirements of efficient logistics and environmental protection. Traditional train bulk loaders have gradually exposed numerous technical bottlenecks that urgently need to be overcome over the long term.

[0003] In terms of material flow control, traditional bulk loaders use single-stage valve control. Its working principle is to rely on the change of the opening of a single valve to roughly adjust the falling speed and flow of materials. However, granular materials have characteristics such as particle size differences and unstable fluidity. For example, wet coal particles are easy to stick together and agglomerate, while dry ore particles are relatively loose. When transporting materials, single-stage valves are difficult to accurately respond to changes in material state. If the valve opening is too small, it is easy to cause blockage due to material accumulation. If the opening is too large, the material will pour out quickly and accumulate into a hill in the carriage. Not only can the material not be evenly distributed, but it also requires subsequent manual secondary operation. The material movement will generate induced airflow, which will carry away dust. Traditional bulk loader uses a dust bag on the outside of the discharge chute to collect dust. This method requires a short distance between the material discharge outlet and the ground to effectively prevent dust from escaping, and the chute needs to be extended and retracted up and down, resulting in low material discharge efficiency and unsuitable for large-scale continuous loading of trains. The unloading of traditional train granule bulk loader is highly dependent on manual adjustment, which is not convenient for mixed operation of trains with different carriage heights, thus reducing the unloading efficiency. Summary of the Invention

[0004] The object of the present invention is to provide a train particle bulk loader to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a train particle bulk loader, comprising a gantry and a bulk platform provided on the gantry, wherein the bulk platform comprises a primary platform located below and a secondary platform located above, a dust cover adjustment assembly is provided on the primary platform, the dust cover adjustment assembly is connected to a discharge valve assembly, and a filter assembly is provided between the discharge valve assemblies; The bulk platform is provided with a fence, and the bulk platform is fixed to the crossbeam of the gantry by bolts; The dust cover adjustment assembly includes a dust cover plate, a fixed pulley, a steel rope, a distance sensor, and an electric rope winding mechanism. The fixed pulley is symmetrically welded to the top outer side of the dust cover plate. One end of the steel rope passes through the first platform and is connected to the bottom surface of the second platform. The other end is connected to the electric rope winding mechanism. The steel rope is wound around the fixed pulley and slides in engagement. The position height of the dust collection cover is input through the console so that it is 30 cm away from the top of the train car. The console controls the electric rope winding mechanism on the first-level platform to extend and lower the steel rope. The dust collection cover at the lower end of the steel rope descends steadily under the action of gravity, driving the unloading chute and the dust removal telescopic hose to the specified height. This design can freely adjust the height of the unloading chute and the dust collection cover, so that it can better adapt to different car heights for loading and unloading operations, greatly improving the practicality of the equipment.

[0006] The unloading valve assembly includes a pneumatic flat gate valve, an electric fan-shaped valve, an inlet, a dust-proof telescopic hose and a discharge chute. The pneumatic flat gate valve is arranged below the inlet. The electric fan-shaped valve is connected to the pneumatic flat gate valve. The bottom of the electric fan-shaped valve passes through the secondary platform and is connected to the dust-proof telescopic hose. The dust-proof telescopic hose is connected to the discharge chute.

[0007] When loading materials, the control console first controls the pneumatic flat gate valve to quickly cut off the initial material flow channel, completes the material closure in the equipment standby state, and controls the initial opening of the electric fan valve to 45° to control the unloading at an appropriate speed. When preparation is complete, the pneumatic flat gate valve is opened for unloading. The material falls from the telescopic unloading chute inside the three dust-proof telescopic hoses and is unloaded into the train car at the same time. The three symmetrically arranged unloading chutes can evenly spread the material into the car. The ranging sensor on the dust collection cover monitors the height of the particulate matter in the car in real time and feeds back to the control console. When it is detected that the height of the coal pile in the car reaches two-thirds of the car height, the control console controls the opening of the electric fan valve to 30° and simultaneously starts the filter component. At this time, the pneumatic flat gate valve adjusts the opening to assist in stabilizing the flow to avoid blockage of the unloading chute due to material impact.

[0008] Furthermore, a control console is fixed on the secondary platform by screws, a base plate is welded to the bottom of both ends of the gantry, the distance measuring sensor is symmetrically fixed on the dust collection cover plate by screws, the top of the unloading chute passes through the primary platform, and the bottom is connected to the dust collection cover plate, and the control console is electrically connected to the distance measuring sensor.

[0009] Furthermore, the fixed base plate is fixed to the bottom surface by expansion screws, a loading train is provided between the fixed base plates, the loading train is located directly below the dust collection cover plate, and the control console is electrically connected to the power motor.

[0010] When the distance sensor detects that the compartment is full of particulate matter, the console closes the pneumatic flat gate valve to prevent the material from scattering outside the compartment.

[0011] Furthermore, the electric rope winding mechanism includes a guide wheel, an electric reducer, a bearing, a reel and a rotating shaft. One end of the steel rope is wrapped around the guide wheel and wound around the reel. The reel is symmetrically welded on the rotating shaft. The middle part of the rotating shaft passes through the bearing and rotates together. The bearing is arranged between the reels, and the electric reducer is electrically connected to the control console.

[0012] Furthermore, a mounting box is symmetrically fixed on the first-level platform by screws, the guide wheel is symmetrically embedded in one side of the mounting box and rotates together, one end of the rotating shaft is embedded in the mounting box and rotates together, and the other end is connected to the electric reducer, and the electric reducer is arranged on the outside of the mounting box.

[0013] The console controls the two electric reducers on the first-level platform to start synchronously. The electric reducers make the shaft rotate clockwise at a uniform speed. The shaft drives the reel to rotate with the auxiliary support of the bearing, thereby releasing the steel rope wrapped around the reel. Under the support and guidance of the guide wheel, the steel rope extends and lowers.

[0014] Furthermore, the filter assembly includes a dust removal telescopic hose, a dust removal box, a fan, a motor, an air duct, a frame filter bag and a filter bag cleaning part. The bottom of the dust collection cover is a hollow structure, and is connected to the lower end of the dust removal telescopic hose and the discharge chute. The upper end of the dust removal telescopic hose is connected to the dust removal box.

[0015] Furthermore, a number of frame filter bags are hung inside the dust removal box, and the upper and lower parts of the frame filter bags are separated by the dust removal box. The fan is fixed to the first-level platform by bolts. A motor is provided on one side of the fan. The fan is connected to one end of the air duct, and the other end of the air duct passes through the dust removal box and is arranged above the frame filter bag. The motor is electrically connected to the control console.

[0016] During dust removal, the motor is started, driving the fan to operate. The fan continuously extracts air from the dust removal box through the air duct, and the pressure in the dust removal box is reduced, thereby generating negative pressure on the dust collection cover plate connected to it through the dust removal telescopic hose. The dust generated by the falling coal ash is attracted by the negative pressure and continuously enters the dust removal telescopic hose. After rising to the dust removal box, the coal ash is filtered out by the frame filter bag, and fresh air is discharged from the fan, thereby avoiding the problem of dust escape and pollution of the working environment.

[0017] Furthermore, the filter bag cleaning component includes an air storage bag, an electromagnetic pulse valve and an injection pipe. The air storage bag is fixed to the outside of the dust removal box by bolts. One side of the air storage bag is connected to several equally spaced electromagnetic pulse valves. The electromagnetic pulse valves are connected to the injection pipe through pipes. The injection pipe is arranged directly above the frame filter bag. A timing controller is fixed to one side of the dust removal box by screws, and the timing controller is electrically connected to the electromagnetic pulse valve.

[0018] The timing controller regularly starts the electromagnetic pulse valve, which instantly opens the pipe connecting the jet pipe and the air storage bag. The compressed gas in the air storage bag is instantly ejected from the jet pipe, and the impact airflow hits the silted gaps of the frame bag from top to bottom, thereby removing the coal dust on it, avoiding blockage of the frame bag and causing poor airflow operation, which affects the negative pressure effect generated by the dust collection cover.

[0019] Furthermore, a manual rod valve assembly is provided between the pneumatic flat gate valve and the feed port. The manual rod valve assembly includes a hollow box, a handle, a rod and a socket. A hollow hole is provided on the top of the hollow box and is connected to the feed port through a flange. The bottom of the hollow box is fixed to the pneumatic flat gate valve by bolts.

[0020] Furthermore, the sockets are provided in plurality and are equidistantly arranged on both sides of the hollow box. The rod passes through the sockets and extends into the interior of the hollow box. One end of the rod is conical and abuts against each other. The handle is an L-shaped structure and is welded to one end of the rod. The handle is arranged outside the hollow box.

[0021] When the bulk loader is loading and unloading ore, a manual rod valve assembly is added between the pneumatic flat gate valve and the feed port. According to the requirements of the iron ore particle size, the rod is pulled out of the socket using the pull handle, and the gap distance between the two adjacent rods is controlled, thereby controlling the size of the unloading particle size. The high-frequency jitter of the electric fan valve is used to vibrate and remove the ore that has not passed the screening. When there is a risk of short-term high-flow impact in material transportation, the pneumatic flat gate valve will act quickly, and through precise throttling, it will buffer the inertia of the ore falling, and cooperate with the electric fan valve to keep the unloading channel unobstructed. Through the coordinated action of each valve, it can achieve uniform distribution that accurately responds to changes in material state when there are differences in particle size and unstable fluidity.

[0022] Compared with the prior art, the present invention provides a train granule bulk loader with the following beneficial effects: 1. The train pellet bulk loader can accurately respond to changes in material state through the coordinated action of pneumatic flat gate valves, electric fan valves and manual rod valves. The manual rod valve can adjust the rod gap to control the particle size, the electric fan valve can adjust the material flow to control the material falling speed, and the pneumatic flat gate valve can accurately throttle when the material impacts, buffer the falling inertia, ensure the unloading channel is unobstructed, and achieve uniform material distribution.

[0023] 2. The train particle bulk loader uses a fan to extract air to create negative pressure on the dust cover, which absorbs dust during particle discharge and filters it through dust removal filter bags to effectively prevent dust pollution. The electric reducer is controlled by the console to drive the reel to release the steel rope. The height of the dust cover and the discharge chute can be freely adjusted to adapt to loading and unloading operations at different carriage heights, improving the practicality of the equipment. The distance sensor monitors the accumulation height of the particles and the linkage valve adjusts the flow rate to avoid blockage. BRIEF DESCRIPTION OF THE DRAWINGS

The dust cover adjustment component 3 is connected to a discharge valve component 4. A filter component 5 is provided between the discharge valve components 4. The bulk platform 2 is provided with a fence 23, and the bulk platform 2 is fixed to the crossbeam of the gantry 1 by bolts; The dust cover adjustment assembly 3 includes a dust cover plate 31, a fixed pulley 32, a steel rope 33, a distance sensor 34, and an electric rope winding mechanism. The fixed pulley 32 is symmetrically welded to the top outer side of the dust cover plate 31. One end of the steel rope 33 passes through the first platform 21 and is connected to the bottom surface of the second platform 22. The other end is connected to the electric rope winding mechanism. The steel rope 33 is wound around the fixed pulley 32 and slides in engagement. The position height of the dust collection cover 31 is input through the control console 6 so that it is 30 cm away from the top of the train car. The control console 6 controls the electric rope winding mechanism on the first-level platform 21 to extend and lower the steel rope 33. The dust collection cover 31 at the lower end of the steel rope 33 steadily descends under the action of gravity, driving the unloading chute 45 and the dust removal telescopic hose 51 to reach the specified height. This design can freely adjust the height of the unloading chute 45 and the dust collection cover 31, so that it can better adapt to different car heights for loading and unloading operations, greatly improving the practicality of the equipment.

[0028] The unloading valve assembly 4 includes a pneumatic flat gate valve 41, an electric fan-shaped valve 42, an inlet 43, a dust-proof telescopic hose 44 and a discharge chute 45. The pneumatic flat gate valve 41 is arranged below the inlet 43, the electric fan-shaped valve 42 is connected to the pneumatic flat gate valve 41, the bottom of the electric fan-shaped valve 42 passes through the secondary platform 22 and is connected to the dust-proof telescopic hose 44, and the dust-proof telescopic hose 44 is connected to the discharge chute 45.

[0029] When loading materials, the control console 6 first controls the pneumatic flat gate valve 41 to quickly cut off the initial material flow channel, completes the material closure in the standby state of the equipment, and controls the initial opening of the electric fan valve 42 to 45° to control the unloading at an appropriate speed. After preparation, the pneumatic flat gate valve 41 is opened for unloading, and the material falls from the dust-proof telescopic hose 44 into the three unloading chutes 45 and is unloaded into the train car at the same time. The three symmetrically arranged unloading chutes 45 can make the material evenly spread into the car. The distance sensor 34 on the dust collection cover 31 monitors the height of the coal pile in the car in real time and feeds back to the control console 6. When it is detected that the height of the coal pile in the car reaches two-thirds of the car height, the control console 6 controls the opening of the electric fan valve 42 to 30° and simultaneously starts the filter component 5. At this time, the pneumatic flat gate valve 41 adjusts the opening to assist in stabilizing the flow to avoid blockage of the unloading chute 45 due to material impact.

[0030] Furthermore, a control console 6 is fixed to the secondary platform 22 by screws, a base plate 11 is welded and fixed to the bottom of both ends of the gantry 1, and the distance measuring sensor 34 is symmetrically fixed to the dust collection cover 31 by screws. The top of the unloading chute 45 passes through the primary platform 21, and the bottom is connected to the dust collection cover 31. The control console 6 is electrically connected to the distance measuring sensor 34.

[0031] Furthermore, the fixed base plate 11 is fixed to the bottom surface by expansion screws, and a loading train 7 is provided between the fixed base plates 11 . The loading train 7 is located directly below the dust collection cover plate 31 , and the console 6 is electrically connected to the power motor 13 .

[0032] When the distance measuring sensor 34 detects that the compartment is full of particulate matter, the control console 6 starts the pneumatic flat gate valve 41 to close to prevent the material from scattering outside the compartment.

[0033] Furthermore, the electric rope winding mechanism includes a guide wheel 35, an electric reducer 36, a bearing 37, a reel 38 and a rotating shaft 39. One end of the steel rope 33 is wrapped around the guide wheel 35 and wound on the reel 38. The reel 38 is symmetrically welded on the rotating shaft 39. The middle part of the rotating shaft 39 passes through the bearing 37 and rotates together. The bearing 37 is arranged between the reel 38, and the electric reducer 36 is electrically connected to the control console 6.

[0034] Furthermore, a mounting box 211 is symmetrically fixed on the first-level platform 21 by screws, the guide wheel 35 is symmetrically embedded in one side of the mounting box 211 and rotates together, one end of the rotating shaft 39 is embedded in the mounting box 211 and rotates together, and the other end is connected to the electric reducer 36, which is arranged on the outside of the mounting box 211.

[0035] The console 6 controls the two electric reducers 36 on the first-level platform 21 to start synchronously. The electric reducer 36 causes the rotating shaft 39 to rotate clockwise at a uniform speed. The rotating shaft 39 drives the reel 38 to rotate with the auxiliary support of the bearing 37, thereby releasing the steel rope 33 wound on the reel 38. Under the support and guidance of the guide wheel 35, the steel rope 33 extends and lowers.

[0036] Furthermore, the filter assembly 5 includes a dust removal telescopic hose 51, a dust removal box 52, a fan 53, a motor 54, an air duct 55, a frame filter bag 56 and a filter bag cleaning part. The bottom of the dust collection cover 31 is a hollow structure, and is connected to the lower end of the dust removal telescopic hose 51 and the unloading chute 45. The upper end of the dust removal telescopic hose 51 is connected to the dust removal box 52.

[0037] Furthermore, a number of frame filter bags 56 are suspended inside the dust removal box 52, and the upper and lower parts of the frame filter bags 56 are separated by the dust removal box 52. The fan 53 is fixed to the first-level platform 21 by bolts. A motor 54 is provided on one side of the fan 53. The fan 53 is connected to one end of the air duct 55. The other end of the air duct 55 passes through the dust removal box 52 and is arranged above the frame filter bag 56. The motor 54 is electrically connected to the control console 6.

[0038] During dust removal, the motor 54 is started, driving the fan 53 to operate. The fan 53 continuously extracts air from the dust removal box 52 through the air duct 55, and the pressure in the dust removal box 52 is reduced, thereby generating a negative pressure on the dust collection cover 31 connected to it through the dust removal telescopic hose 51. The dust generated by the falling coal ash is attracted by the negative pressure and continuously enters the dust removal telescopic hose 51. After rising to the dust removal box 52, the coal ash is filtered out by the frame filter bag 56, and fresh air is discharged from the fan 53, thereby avoiding the problem of dust escaping and polluting the working environment.

[0039] Furthermore, the filter bag cleaning component includes an air storage bag 57, an electromagnetic pulse valve 58 and an injection pipe 59. The air storage bag 57 is fixed to the outside of the dust removal box 52 by bolts. One side of the air storage bag 57 is connected to several equally spaced electromagnetic pulse valves 58. The electromagnetic pulse valves 58 are connected to the injection pipe 59 through pipes. The injection pipe 59 is arranged directly above the frame filter bag 56. A timing controller 521 is fixed to one side of the dust removal box 52 by screws, and the timing controller 521 is electrically connected to the electromagnetic pulse valve 58.

[0040] The timing controller 521 regularly starts the electromagnetic pulse valve 58, and the electromagnetic pulse valve 58 instantly opens the pipe connecting the jet pipe 59 and the air storage bag 57. The compressed gas in the air storage bag 57 is instantly ejected from the jet pipe 59, and the impact airflow hits the silted gaps of the frame bag 56 from top to bottom, thereby removing the coal dust thereon, avoiding blockage of the frame bag 56 causing poor airflow and affecting the negative pressure effect generated by the dust collection cover 31. Example 2

[0041] See also Figure 5 and Figure 8 The difference between Example 2 and Example 1 is that a manual rod valve assembly 8 is provided between the pneumatic flat gate valve 41 and the feed inlet 43. The manual rod valve assembly 8 includes a hollow box 81, a handle 82, a rod 83 and a socket 84. A hollow hole 811 is provided on the top of the hollow box 81 and is connected to the feed inlet 43 through a flange. The bottom of the hollow box 81 is fixed to the pneumatic flat gate valve 41 by bolts.

[0042] Furthermore, there are several sockets 84 that are equidistantly arranged on both sides of the hollow box 81. The rod 83 passes through the sockets 84 and extends into the interior of the hollow box 81. One end of the rod 83 is conical and abuts against each other. The handle 82 is an L-shaped structure and is welded to one end of the rod 83. The handle 82 is arranged on the outside of the hollow box 81.

[0043] When the bulk loader is performing ore loading and unloading operations, a manual rod valve assembly 8 is added between the pneumatic flat gate valve 41 and the feed port 43. According to the requirements of the iron ore particle size, the rod 83 is pulled out from the socket 84 using the pull handle 82, thereby controlling the gap distance between the two adjacent rods 83, thereby controlling the size of the unloaded material. The high-frequency jitter of the electric fan valve 42 is used to vibrate and remove the ore that has not passed the screening. When there is a risk of short-term high-flow impact in material transportation, the pneumatic flat gate valve 41 acts quickly, and through precise throttling, it buffers the inertia of the ore falling, and cooperates with the electric fan valve 42 to maintain the unobstructed discharge channel. Through the coordinated action of each valve, a uniform distribution of materials that accurately responds to changes in material state when there are differences in particle size and unstable fluidity is achieved.

[0044] The specific usage and function of this embodiment are as follows: The hopper 36 is then moved to the right of the top of the platform 21 and the hopper 37 is moved to the left of the platform 21. The hopper 36 is moved to the right of the top of the platform 21 and the hopper 37 is moved to the right of the top of the platform 21. The hopper 36 is moved to the right of the top of the platform 21 and the hopper 37 is moved to the right of the top of the platform 21. When loading materials, the control console 6 first controls the pneumatic flat gate valve 41 to quickly cut off the initial material flow channel, completes the material closure in the standby state of the equipment, and controls the initial opening of the electric fan valve 42 to 45° to control the unloading at an appropriate speed. After preparation, the pneumatic flat gate valve 41 is opened to unload, and the material falls from the dust-proof telescopic hose 44 into the three unloading chutes 45 and is unloaded into the train car at the same time. The three symmetrically arranged unloading chutes 45 can make the material evenly spread into the car. The distance sensor 34 on the dust collection cover 31 monitors the height of the particles in the car in real time and feeds back to the control console 6. When it is detected that the height of the particles in the car reaches two-thirds of the height of the car, the control console 6 controls the opening of the electric fan valve 42 to 30° and starts the filter component 5 simultaneously. At this time, the pneumatic flat gate valve 41 adjusts the opening to assist in stabilizing the flow to avoid blockage of the unloading chute 45 due to material impact. During dust removal, the motor 54 is started, driving the fan 53 to operate. The fan 53 continuously extracts air from the dust box 52 through the air duct 55, reducing the pressure in the dust box 52. This in turn generates a negative pressure on the dust collecting cover 31 connected to the dust collecting cover 31 via the dust collecting telescopic hose 51. The dust generated by the falling particles is attracted by the negative pressure and continuously enters the dust collecting telescopic hose 51. After rising to the dust collecting box 52, the dust is filtered out by the frame filter bag 56. Fresh air is then discharged from the fan 53, thereby preventing dust from escaping and polluting the working environment. The timing controller 521 periodically activates the electromagnetic pulse valve 58, which instantly opens the pipe connecting the air jet pipe 59 and the air storage bag 57. The compressed gas in the air storage bag 57 is instantly ejected from the air jet pipe 59. The impact airflow hits the silted gaps of the frame bag 56 from top to bottom, thereby removing the particles thereon, avoiding blockage of the frame bag 56 and causing poor airflow, which would affect the negative pressure effect generated by the dust collection cover 31. Finally, when the distance sensor 34 detects that the compartment is full of particles, the control console 6 closes the pneumatic flat gate valve 41 to prevent the material from scattering outside the compartment; When the bulk loader is performing ore loading and unloading operations, a manual rod valve assembly 8 is added between the pneumatic flat gate valve 41 and the feed port 43. According to the requirements of the iron ore particle size, the rod 83 is pulled out from the socket 84 using the pull handle 82, thereby controlling the gap distance between the two adjacent rods 83, thereby controlling the size of the unloaded material. The high-frequency jitter of the electric fan valve 42 is used to vibrate and remove the ore that has not passed the screening. When there is a risk of short-term high-flow impact in material transportation, the pneumatic flat gate valve 41 acts quickly, and through precise throttling, it buffers the inertia of the ore falling, and cooperates with the electric fan valve 42 to maintain the unobstructed discharge channel. Through the coordinated action of each valve, a uniform distribution of materials that accurately responds to changes in material state when there are differences in particle size and unstable fluidity is achieved.
