Description

Technical Field

[0001] The invention relates to the field of integral roadbed cleaning and coal ash sweeping and collection in railway tunnels, and in particular to a tunnel abandoned fine coal cleaning device and a use method thereof. Background Art

[0002] The problem of fly ash pollution in the railway track has long been a major problem that needs to be solved in the field of railway transportation, especially in the tunnel section, where its complexity and severity are more prominent. As an important part of the railway line, the maintenance of the internal environment of the tunnel is directly related to the safe operation of the train and the long-term stability of the equipment. However, due to the significant role of the piston wind effect in the tunnel, the deposition of fine particles such as fly ash has become increasingly serious, not only covering the surface of the track bed, but also gradually penetrating into the track bed structure, which has an unignorable impact on the elastic performance of the railway track bed. The reduction of the track bed elasticity will directly affect the smoothness and ride comfort of the train operation, and may even cause safety accidents such as derailment in severe cases. In addition, the deposition of fly ash also seriously interferes with the drainage system of the tunnel. The original intention of the design of the tunnel drainage facilities is to timely remove surface water and groundwater to ensure the dryness and safety of the tunnel structure. However, the accumulation of fly ash blocks the drainage holes and drainage ditches, resulting in the inability to discharge the accumulated water smoothly, which in turn aggravates the corrosion and aging of the tunnel structure and reduces the overall safety performance of the tunnel.

[0003] Since fly ash contains a large amount of harmful gases and tiny particles, the air quality in the tunnel is often poor, posing a serious threat to the respiratory system and other organs of employees. Working in this environment for a long time may not only cause employees to suffer from occupational diseases, but also affect work efficiency and safety due to physical discomfort.

[0004] At present, the cleaning of impurities such as coal ash in tunnels mainly relies on traditional methods such as manual cleaning, bagging and manual handling, supplemented by the cooperation of rail cars. However, this method has many disadvantages. First, manual cleaning is inefficient, time-consuming and labor-intensive, and requires a large amount of human resources. Taking the cleaning of coal ash in a tunnel of the Haoji Railway as an example, cleaning 600 cubic meters of coal ash requires a lot of manpower and time costs, which poses a severe challenge to the continuity and efficiency of railway transportation. Secondly, there are safety hazards in the manual cleaning process. Harmful substances in coal ash may cause harm to the human body through respiratory and skin contact, posing a potential threat to employee health. In addition, although mechanical cleaning equipment has improved the cleaning efficiency to a certain extent, it often has problems such as incomplete cleaning and easy damage to equipment, and the secondary dust generated during the cleaning process is also an environmental problem that needs to be solved urgently.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0024] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings: The first object of the present invention is to provide a device for cleaning the coal left behind in a tunnel. Figure 1 As shown, it includes a bottom mounting platform (exemplarily, the mounting platform is a rail car) and a cleaning module, a collection module, a dust removal and filtering module, a transport module and a storage module on the bottom mounting platform; The cleaning module is used to carry the fine coal dust and particulate matter to the collection module; The collecting module is used to collect the fine coal dust and particulate matter brought up by the cleaning module; The dust removal and filtration module is used to remove and filter the fine coal dust and particulate matter in the collection module, and then transport them to the collection module after dust removal and filtration; The transport module is used to transport the final coal dust and particulate matter after dust removal and filtration to the storage module for storage; The power module is electrically connected to the cleaning module, the collecting module, the dust removal and filtering module, the transport module and the storage module.

[0027] The cleaning module can effectively pick up the fallen coal dust and particles on the tunnel floor, ensuring the cleanliness of the tunnel floor and reducing the potential safety hazards caused by coal accumulation; the collection module is responsible for receiving the coal dust and particles picked up by the cleaning module, preventing these substances from floating around in the tunnel, thereby keeping the working environment clean. At the same time, the collection module has a large capacity and can accommodate more coal dust and particles, reducing the need for frequent cleaning and improving work efficiency. The dust removal and filtration module removes and filters the coal dust and particles in the collection module, effectively removing the dust components therein, making the final collected coal purer, which not only improves the reuse value of coal, but also reduces the harm of dust to the environment and human health. The coal dust and particles that have been dusted and filtered are then transported to the collection module; the transportation module is responsible for transporting the coal dust and particles that have been dusted and filtered from the collection module to the storage module for storage, realizing the automated processing of coal and reducing the labor intensity of manual handling. The storage module is used to store the fine coal dust and particulate matter after dust removal and filtration, which not only facilitates the reuse of fine coal, but also reduces the environmental pollution caused by random stacking. The power module serves as the energy supply center of the entire system, providing the necessary power drive for the cleaning module, collection module, dust removal and filtration module, transportation module and storage module.

[0028] The cleaning module includes a cleaning roller; Figure 2 As shown, the cleaning roller includes a cleaning roller body, a dust shield 4, a cleaning brush 3 and a driving motor 20; the driving motor 20 is connected to the cleaning roller body; the cleaning roller body is respectively connected to the cleaning brush 3 and the dust shield 4. The driving motor 20 drives the cleaning roller body to rotate, and the cleaning brush 3 picks up the fine coal dust and particulate matter through rotation, thereby increasing the gas flow utilization rate. The material of the cleaning brush 3 is usually selected from soft and wear-resistant fiber materials to ensure that no damage is caused to the tunnel floor during the cleaning process. The dust shield 4 is connected to the cleaning roller body, which can effectively prevent the fine coal dust and particulate matter from splashing around during the cleaning process. The dust shield 4 has a certain inclination angle and height to ensure that the splashing dust and particulate matter can be effectively blocked.

[0029] The cleaning roller also includes a lifting rod 2; the cleaning roller body is connected to the collection module via a first connecting pipe; the outer wall of the first pipe is connected to the lifting rod 2. The lifting rod 2 enables the cleaning roller to adjust its height as needed. Different height changes or obstacles may exist on different tunnel floors. The lifting rod 2 allows the cleaning roller to flexibly adjust its height to ensure that it can closely fit the ground for cleaning while avoiding collision with obstacles. When the cleaning brush 3 needs to be maintained or replaced, the lifting rod 2 can easily lift the cleaning roller to an appropriate height to provide sufficient operating space for the staff. The combination of the lifting rod 2 and the first pipe enables the cleaning module to have greater adaptability and flexibility while maintaining efficient cleaning.

[0030] like Figure 3 As shown, the collection module includes a Roots blower and a spiral particle collector 5 connected thereto; the spiral particle collector 5 is connected to the first pipeline. The Roots blower is connected to the spiral particle collector 5, providing a rotary gas power to form a negative pressure, so that the fine coal dust and particulate matter brought up by the rotation of the cleaning brush 3 are sucked into the spiral particle collector 5 along the first gas inlet connection port 6, and rotate and sink along the gas movement direction of the inner wall of the rotary pipeline 10.

[0031] The dust removal and filtering module includes a dust removal box 11; Figure 4 As shown, the dust removal box 11 is respectively connected to the first pipe and the spiral particle collector 5, and most of the fine coal dust and particulate matter brought up by the rotation of the cleaning brush 3 rotate and sink along the gas movement direction of the inner wall of the swirling pipe 10 (large particles of coal ash fall to the bottom due to gravity and are directly deposited at the bottom of the spiral particle collector 5), while the very small amount of dust that is not deposited enters the dust removal box 11 through the first gas exhaust connection port 7 and then through the second gas inlet connection port 12. The dust removal box 11 is connected to the air compressor. After the dust enters the dust removal box 11, part of it is adsorbed on the air filter bag 14. The air compressor provides positive pressure to blow off the dust adsorbed on the air filter bag 14 to prevent the air filter bag 14 from being blocked and the gas from flowing smoothly. The filtered gas is discharged through the second gas discharge connection port 13. The blown-off dust is deposited at the bottom of the dust removal box 11. The bottom of the dust removal box 11 is provided with a second dust recovery connection port 16. The blown-off dust passes through the second dust recovery connection port 16 and then passes through the first dust recovery connection port 7 inside the spiral particle collector 5 to enter the spiral particle collector 5, achieving secondary collection. At the same time, an observation window 15 is provided on the surface of the dust removal box 11 to check the deposition amount. The bottom of the spiral particle collector 5 is provided with a material transmission connection port 8. The material deposited at the bottom of the spiral particle collector 5 enters the transport module through the material transmission connection port 8. The spiral particle collector 5 is also provided with an explosion-proof device. When the explosion-proof device detects that the air pressure is too high, it will automatically open and release the pressure to avoid the explosion of coal ash and dust.

[0032] The transport module includes a spiral conveying pipe 17; one end of the spiral conveying pipe 17 is connected to the material transmission connection port 8 of the spiral particle collector 5, and the other end is connected to the storage module. The spiral conveying pipe 17 can continuously and stably convey the dust and particulate matter that have been filtered and removed from the spiral particle collector 5 to the storage module through the spiral blade structure inside it, ensuring that the material is not blocked or scattered during the conveying process. The spiral conveying pipe 17 can adapt to different material properties and conveying distances. By adjusting the parameters such as the pitch, rotation speed and material of the spiral blade, it can realize the conveying of materials with different particle sizes, densities and humidity.

[0033] The storage module includes a feed pipe 18; the feed pipe 18 is connected to the spiral conveying pipe 17; a feed valve 19 is arranged on the feed pipe 18; the feed pipe 18 is connected to the storage bin 23 through the feed valve 19. The storage module receives materials from the spiral conveying pipe 17 through the feed pipe 18, and conveys them to the storage bin 23. The feed valve 19 is installed on the feed pipe 18 to control the flow of materials. When materials need to be stored in the storage bin 23, the feed valve 19 is opened, and the materials enter the storage bin 23 through the feed pipe 18; when the materials in the storage bin 23 reach a predetermined level or need to stop adding, the feed valve 19 is closed to cut off the flow of materials. The feed valve 19 is of great significance for maintaining a constant supply of materials in the storage bin 23 and preventing materials from overflowing. Specifically, if Figure 5 As shown, there are five storage bins 23, and the material enters the feed pipe 18 through the spiral conveying pipe 17. The feed pipe 18 is provided with five feed valves 19, and the five feed valves 19 are respectively connected to the five storage bins 23. During the operation, the feeding progress is monitored and the 1#, 2#, 3#, 4#, and 5# feed valves 19 in the storage bin 23 are opened in turn, so that the materials fill the 1#, 2#, 3#, 4#, and 5# storage bins 23 in turn.

[0034] The storage bin 23 is connected to the discharge pipe 22. The storage bin 23 is not only used to store materials, but also responsible for providing a stable supply of materials to downstream equipment or processes. By controlling the opening and closing of the discharge pipe 22, the supply amount of materials can be accurately adjusted to meet the needs of the production or processing process. This device realizes semi-automatic unloading. The discharge pipe 22 includes a discharge pipe 1# and a discharge pipe 2# connected thereto, and the discharge pipe 1# is connected to the storage bin 23. When unloading, the discharge pipe 2# is adjusted to a suitable angle, and the motor drives the discharge pipe 1# to work. Five discharge valves 21 are correspondingly set for the 1#, 2#, 3#, 4#, and 5# storage bins 23. The discharge valves 21 of the 1#, 2#, 3#, 4#, and 5# storage bins are opened respectively, and the materials enter the discharge pipe 2# along the discharge pipe 1# and are finally discharged from the discharge port.

[0035] The power module includes a high-power diesel engine; illustratively, the power module provides power (electricity) to the Roots blower, air compressor and various motors, including lighting, etc. The power module is also connected to the power cabinet, which is used to control the switch of the power module to achieve precise control of the power module. When the system needs to start or stop the power module, the control elements in the power cabinet will act according to the preset logic to ensure the smooth start and stop of the power module.

[0036] In summary, the working principle of the device of the present invention is: the power module provides power, the Roots blower provides rotary gas power, the dust, fly ash, small particles of gravel, gravel, etc. brought up by the rotation of the cleaning brush 3 are sucked into the spiral particle collector 5, the air compressor compresses the air to make the air pressurized, and the dust attached to the air filter bag 14 is blown off, and the filtered particulate matter is transmitted to the storage bin 23 for storage through the transport module.

[0037] The second object of the present invention is to provide a method for cleaning a device for cleaning coal left behind in a tunnel, comprising the following steps: S1: Use the cleaning module to bring the fine coal dust and particulate matter in the tunnel to the collection module; S2: A portion of the fine coal dust and particulate matter is stored in the collection module, and the other portion is filtered and dusted by the dust removal and filtration module before being transported to the collection module for storage; S3: The fine coal dust and particulate matter in the collection module are transported to the storage module via the transportation module for storage.

[0038] This device requires the cooperation of a rail car. The average operating speed of the rail car is controlled at about 1km / h, the theoretical air intake is 2400h, the material suction rate is about 10%, and 2 operators are required, which greatly saves manpower and improves operating efficiency, in line with the operating concept of "machine advances and people retreat".

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
