Description

Technical Field

[0001] The invention belongs to the technical field of silo unloading, and in particular relates to a fixed silo unloading and loading control method with a vehicle type self-adaptive function. Background Art

[0002] Boiler slag is a solid waste generated during the coal combustion process. It is the final product formed after the minerals in the coal undergo physical and chemical changes under high temperature. After the boiler slag is produced in the boiler, it will be cleaned out and sent to a fixed silo, and then transported to other locations by transport vehicles and other transportation equipment.

[0003] In the prior art, since the position of the silo is fixed, the transport vehicle needs to be driven to the bottom of the discharge port according to the position of the silo discharge port. During the discharge process, the transport personnel need to judge the height of the boiler slag in the transport vehicle based on their personal feelings and control the displacement of the transport vehicle. However, due to the different types of transport vehicles, the corresponding storage amounts are also different. Through the above process, it is impossible to detect the boiler slag in the transport vehicle, and the judgment is only based on the personal feelings of the transport personnel, resulting in too much or too little material in the transport vehicle. In addition, a lot of dust is often generated during the discharge process, affecting the environmental safety of the discharge area. Summary of the invention

[0050] S3, obtaining vehicle information based on the license plate information, obtaining the corresponding vehicle information from the database, and then the position detection device 13 detects the position information of the transport vehicle 15, and the control device 14 determines the unloading point and the longitudinal displacement range of the unloading according to the information of the transport vehicle 15, and then controls the displacement device to work based on the position information of the transport vehicle 15;

[0051] S4, the displacement device controls the feeding port 1 to move to the feeding point, the control device 14 controls the feeding port 1 to open and remove dust through the dust removal device, during the feeding process, the laser rangefinder 6 detects the boiler slag height information in the vehicle, and the control device 14 controls the upward movement speed of the feeding port 1 based on the boiler slag height change data;

[0052] S5. When the boiler slag height reaches the boiler slag height corresponding to the vehicle information in the database, the discharge port 1 is controlled to be closed, and the transport vehicle 15 is reminded to move. When the transport vehicle 15 moves, the position detection device 13 detects the position of the transport vehicle 15. When the displacement distance is reached, the control device 14 controls the reminder device 16 to prompt the driver to stop. Then the control device 14 discharges the material according to step S4. After all the discharge times are completed, the discharge port 1 moves up and resets. At this time, the transport vehicle 15 can drive out of the parking room 11.

[0053] In this embodiment, the control device 14 establishes a spatial coordinate system based on the position of the parking room 11 and the space size of the parking room 11, and confirms the unloading point based on the position of the position detection device 13 in the spatial coordinate system and the position of the transport vehicle 15 detected by the position detection device 13.

[0054] The control device 14 is an industrial computer, a PLC control circuit or other control device, the position detection device 13 is a laser rangefinder 6 and a visual detector, and the position of the transport vehicle 15 is confirmed based on the distance information detected by the laser rangefinder 6 and the position information captured by the visual detector. The reminder device specifically adopts a speaker or a display screen or a combination thereof to prompt the driver to control the displacement of the transport vehicle 15 through sound or image.

[0055] In this embodiment, the dust removal device includes at least one end plate 2 fixed on the feeding port 1, a dust removal component 3 rotatably connected to the end plate 2, a servo motor 4 for driving the dust removal component 3 to rotate, a water pump 10 fixed on the parking room 11, a water tank 9 connected to the water pump 10, and an exhaust device 7 connected to the dust removal component 3, the servo motor 4 is fixed on the end plate 2, the water pump 10 is connected to the dust removal component 3, and the water tank 9 is fixed on the parking room 11;

[0056] When in use, the water pump 10 fills the dust removal component 3 with water, and is closed after the filling is completed. The air extraction device 7 extracts air, and the dust enters the dust removal component 3 for dust removal. When the transport vehicle 15 is loaded, the servo motor 4 drives the dust removal device to rotate, and the dust removal device pours out the sewage. Then the servo motor 4 drives the dust removal device to rotate and reset, and then water can be added again according to the above process;

[0057] The exhaust device 7 may be an exhaust fan, an air pump or a fan that can extract air.

[0058] In this embodiment, the dust removal assembly 3 includes a cylinder 38 which is hollow inside and connected to the servo motor 4, a water storage shell 36 fixed inside the cylinder 38, a perforated plate 35 fixed on the top of the water storage shell 36, a filter assembly arranged above the perforated plate 35, and a guide tube 37 opened on the inner wall of the water storage shell 36, a channel 31 is vertically opened in the middle of the water storage shell 36, the upper end of the channel 31 is closed, and the channel 31 is connected to the upper part of the guide tube 37;

[0059] The cylinder 38 has openings at both ends, and the upper opening is in rotational sealing contact with a sealing shell 34, which is connected to the air extraction device 7, so that the air extraction device 7 is connected to the upper opening of the cylinder 38;

[0060] The cylinder 38 is provided with a water inlet 32 ​​located between the filter assembly and the orifice plate 35, and the sealing shell 34 is provided with a connection port 33 communicating with the water pump 10;

[0061] The filter assembly knocks the orifice plate 35 and dumps the dust when the cylinder 38 rotates. The filter assembly itself vibrates when dumping the dust. The water in the water storage shell 36 is gradually discharged from the opening above the cylinder 38 during the rotation of the cylinder 38.

[0062] When in use, the water pump 10 discharges water into the cylinder 38 through the connecting port 33 and the water inlet 32, and the water in the circumference flows into the water storage shell 36 through the orifice plate 35. When the water in the water storage shell 36 is located below the connection between the guide tube 37 and the channel 31, the water addition is stopped, and then the air extraction device 7 extracts air from the bottom of the cylinder 38 through the channel 31, the guide tube 37, the water in the water storage shell 36 and the filter component into the air extraction device 7. The air is dusted once when passing through the water, and is dusted twice when passing through the filter component to ensure the dust removal effect. When the dust removal is completed, the servo motor 4 drives the cylinder 38 to rotate 180° counterclockwise. When rotating 0°-60°, the filter component knocks the orifice plate 35. When rotating 60°-120°, the filter component gradually opens, and the water in the water storage shell 36 is discharged. When rotating 120°-180°, the filter component itself vibrates to remove dirt, and then resets and re-adds water.

[0063] The air extraction device 7 and the water pump 10 are both connected to the sealing shell 34 and the connecting port 33 through a retractable hose.

[0064] In this embodiment, the filter assembly includes four pressure regulating assemblies 301 arranged in the horizontal direction and rotatably connected in the cylinder 38, a filter screen 314 arranged on the pressure regulating assembly 301, contact seals 315 sealed and fixed at the left and right ends of the filter screen 314, a connecting barrel 302 connected to the bottom of the pressure regulating assembly 301, a driving assembly A and a driving assembly B, and adjacent contact seals 315, contact seals 315 and the cylinder 38, and filter screen 314 and the cylinder 38 are all in contact and sealed;

[0065] A driving cavity 39 is provided at both axial ends of the cylinder 38. The driving assembly A and the driving assembly B are respectively located in the two driving cavities 39. The driving assembly A and the driving assembly B can be engaged with the end plate 2. The pressure regulating assembly 301 is connected to the driving assembly A to drive the pressure regulating assembly 301 to adjust the pressure and rotate.

[0066] The connecting barrel 302 is connected to the pressure regulating assembly 301. A transmission assembly is arranged in the connecting barrel 302, which is displaced axially along the connecting barrel 302 with the pressure. The driving assembly B is provided with a slide groove for the displacement of the transmission assembly. The driving assembly B is provided with displacement holes 3072 located at both ends of the slide groove. The displacement holes 3072 are transmitted with the displacement of the transmission assembly and the driving assembly B. The connecting barrel 302 rotates with the rotation of the transmission assembly. A plurality of knocking balls 3023 are arranged on the outer circumference of the connecting barrel 302. In the initial state, the knocking balls 3023 are in contact with the orifice plate 35 and are not in contact with the filter assembly. When the cylinder 38 rotates to 120°-180°, the knocking balls 3023 are not in contact with the orifice plate 35 but are in contact with the filter assembly.

[0067] When in use, as the cylinder 38 rotates counterclockwise, the drive component B drives the connecting barrel 302 to rotate through the transmission component at 0°-60°, and the connecting barrel 302 drives the knocking ball 3023 to knock the orifice plate 35, so that the dust on the orifice plate 35 is separated from the orifice plate 35. When the cylinder 38 rotates to 60-120°, as the drive component A works, the drive component B no longer works. At this time, the drive component A drives the pressure regulating component 301 to adjust the pressure, so that the transmission component is displaced axially along the connecting barrel 302, so that the transmission component and the transmission component no longer transmit. Then, as the pressure of the pressure regulating component 301 increases, the pressure Increase, the driving component can gradually drive the filter 314 and the connecting barrel 302 to rotate. During the rotation, the distance between the connecting barrel 302 and the filter 314 is reduced, and when the filter 314 cannot rotate, the transmission component continues to transmit with the driving component B. When the cylinder 38 rotates to 120°-180°, the driving component drives the connecting barrel 302 to rotate and drives the knocking ball 3023 to knock on the filter 314 to remove dust on the filter 314. Similarly, when the cylinder 38 rotates to reset, according to the above process, the transmission is carried out and the filter 314 and the connecting barrel 302 are driven to reset.

[0069] The spring telescopic rod 3013 near one end of the driving assembly A is connected to the connecting barrel 302 and the fixed barrel 3011;

[0070] The axial side surface of the pressure regulating piston 3015 is polygonal;

[0071] The spring telescopic rod 3013 includes a cylinder and a rod body. A spring connected to the rod body is arranged in the cylinder. The rod body is in sealing contact with the cylinder. An annular groove and a vertical hole are opened on the rod body. The sliding hole connects the annular groove and the cylinder. The connecting barrel 302 is rotatably sealed and connected in the annular groove and communicates with the annular groove.

[0072] When in use, the threaded rod rotates with the rotation of the driving component A. During the rotation process, the pressure of the fixed cylinder 3011 gradually increases or decreases, and air is injected into or extracted from the connecting barrel 302 to control the position of the transmission component. As the pressure in the fixed cylinder 3011 changes, the friction between the threaded shaft 3012 and the threaded cylinder 3014 gradually increases until the threaded shaft 3012 can drive the threaded cylinder 3014 to rotate. The threaded cylinder 3014 drives the fixed cylinder 3011 to rotate through the pressure-regulating piston 3015. The fixed cylinder 3011 drives the corresponding connecting barrel 302 to rotate through the spring telescopic rod 3013, thereby ensuring the rotation of the connecting barrel 302.

[0073] In this embodiment, the driving assembly A includes a driving gear 306 meshing with the end plate 2, a worm gear mechanism 30 driven by the driving gear 306, and four transmission gears 311 driven by the worm gear mechanism 30 through a gear set, the four transmission gears 311 are respectively connected to the four threaded shafts 3012, and the four transmission gears 311 are divided into two left and right groups, and the transmission gears 311 in the same group rotate in the same direction, the four filter screens 314 are divided into two left and right groups, and the cross-sections of the two contact seals 315 in the same group and in contact with each other are inclined surfaces with the same inclination angle, and when the filter screens 314 in the same group rotate in the same direction, the inclined surfaces of the two contact seals 315 in the same group and in contact with each other move away from or close to each other;

[0074] When in use, the driving gear 306 meshes with the end plate 2 when the cylinder 38 rotates 60°-120°, and then the worm gear mechanism 30 works and drives the transmission gear 311 to rotate through the gear set, and the transmission gear 311 drives the threaded shaft 3012 to rotate to ensure driving.

At this time, the slave gear 310 meshes with the transmission assembly. Then, when rotating to 120°-180°, the driving gear 306 of the driving assembly B meshes with the cleaning tooth 201. The slave gear 310 drives the connecting barrel 302 to rotate through the transmission assembly. When the cylinder 38 is reset, the slave gear 310 continues to drive the transmission assembly and the connecting barrel 302 to rotate. When rotating 60°-120°, the transmission assembly gradually disengages from the gear ring 3101 from the displacement hole 3072 of the gear 310 and enters the guide ridge 3071 along the spring sheet until it moves to the displacement hole 3072 of the main gear 307. Then, the spring sheet is inserted into the conical teeth of the displacement hole 3072, so that the main gear 307 can drive the transmission assembly to rotate to ensure operation.

The two bevel gears 312 can mesh with the conical teeth and the gear ring 3101 respectively. The connecting barrel 302 is fixed with a sealing disk 303 in contact with the plane side wall of the cylinder 38.

[0080] When in use, according to the rotation angle of the cylinder 38, the bevel gear 312 meshes with the corresponding gear ring 3101 and the conical teeth, and can be displaced along the guide ridge 3071 and the spring sheet to ensure transmission.
