Description

Technical Field

[0001] This utility model relates to the field of coal transportation technology, and in particular to a device for thawing coal blocks loaded on a train. Background Technology

[0002] During coal transportation, especially in cold regions or winter, large amounts of frozen coal often remain around and at the bottom of train carriages after unloading. Current cleaning methods mainly include manual and mechanical cleaning. Manual cleaning requires workers to use tools such as shovels and hammers. In the narrow and harsh environment inside the train carriage, manually chipping away at the frozen coal can damage the carriage due to improper striking. Mechanical cleaning typically uses loaders, excavators, and other equipment, employing robotic arms and specialized tools to remove the frozen coal. However, it is difficult to clean the corners and edges of the train carriage, and there is a risk of collisions with the inner walls of the carriage, causing wear and deformation. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] This utility model provides a coal thawing device for trains, including a box cover and a heating fan; the box cover is used to cover the upper opening of the train box; the box cover has an accommodating cavity; the heating fan is disposed in the accommodating cavity and is used to generate hot gas; the air inlet of the heating fan is provided with an air inlet pipe, and the air outlet of the heating fan is provided with an air outlet pipe; the air intake of the air inlet pipe and the air exhaust of the air outlet pipe are both disposed at the bottom of the train box.

[0006] Preferably, both the air inlet duct and the air outlet duct are flexible pipes.

[0007] Preferably, the lid is equipped with a sealing device on the side of the upper opening of the train car body.

[0008] Preferably, the sealing device is a sealing ring.

[0009] Preferably, the heating fan has a control panel through which the outlet air temperature and outlet air speed parameters of the heating fan can be set.

[0010] Preferably, the lid is made of iron.

[0011] The present invention achieves the following technical advantages over the prior art:

[0012] The coal thawing device for trains provided by this utility model thaws frozen coal blocks around and at the bottom of the train car body after coal is unloaded by closing the lid onto the car body. The heating fan draws in cold air from the bottom of the train car body, heats it, and then discharges it from the exhaust vent of the air outlet, ensuring that the hot air is evenly distributed throughout the train car body, exchanging heat with the frozen coal blocks and continuously circulating within the train car body. Compared to manual and traditional mechanical cleaning, this hot air circulation thawing method can quickly thaw frozen coal blocks, greatly shortening the cleaning time. It also eliminates the need for manual hammering, reducing the labor intensity and working time of workers in harsh environments. Furthermore, it avoids the collision and damage to the train car body caused by mechanical cleaning, extending the service life of the train car body. Attached Figure Description

[0020] Example 1

[0021] This embodiment provides a device for thawing coal blocks loaded on a train, such as... Figure 1 and Figure 2 As shown, it includes a box cover 1 and a heating fan 2; the box cover 1 is used to cover the upper opening of the train box body 5; the box cover 1 has a cavity; the heating fan 2 is arranged in the cavity and is used to generate hot gas; the air inlet of the heating fan 2 is provided with an air inlet pipe 3, and the air outlet of the heating fan 2 is provided with an air outlet pipe 4; the air inlet of the air inlet pipe 3 and the air outlet of the air outlet pipe 4 are both arranged at the bottom of the train box body 5.

[0022] By closing the lid 1 onto the train car body 5, after the coal is unloaded from the train car body 5, the frozen coal blocks around and at the bottom of the train car body 5 can be thawed by the heating action of the heating fan 2. The heating fan 2 draws in the cold air from the bottom of the train car body 5, heats it, and then discharges it from the exhaust port of the air outlet duct 4, so that the hot air is evenly distributed to all corners of the train car body 5, exchanging heat with the frozen coal blocks and continuously circulating inside the train car body 5. Compared with manual and traditional mechanical cleaning, the hot air circulation thawing method can quickly thaw the frozen coal blocks, greatly shortening the cleaning time; it also eliminates the need for manual knocking, reducing the labor intensity and working time of workers in harsh environments; and it avoids the collision and damage to the train car body 5 caused by mechanical cleaning, extending the service life of the train car body 5.

[0023] In the optional schemes of this embodiment, it is more preferred that both the air inlet duct 3 and the air outlet duct 4 are flexible pipes.

[0024] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 As shown, the box cover 1 is used to cover the upper opening of the train box 5 and a sealing device is provided on one side.

[0025] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 As shown, the sealing device is a sealing ring 6.

[0026] In the optional solutions of this embodiment, it is more preferred that the heating fan 2 has a control panel, through which the outlet air temperature and outlet air speed parameters of the heating fan 2 can be set.

[0027] Specifically, generally, for lightly frozen coal, the temperature is set at 50℃~70℃ and the wind speed at 5m / s~8m / s; for heavily frozen coal, the temperature is set at 70℃~90℃ and the wind speed at 8m / s~12m / s. The specific parameter settings can be adjusted according to the degree of freezing of the coal and the ambient temperature. By rationally setting the parameters of the heating fan, heat supply can be precisely controlled, reducing energy waste and eliminating the generation of additional pollutants.

[0028] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 As shown, the material of the box cover 1 is iron.

[0029] Specifically, the operating procedure is as follows: Place the lid 1 over the train carriage 5, ensuring a good seal. Based on the degree of coal freezing and the ambient temperature, set appropriate wind speed and temperature parameters on the control panel of the heating fan 2, start the hot air fan, and begin circulating hot air within the train carriage 5. Continuously observe the coal's thawing process. When the coal is ready for cleaning, turn off the heating fan 2, remove the lid 1, and proceed with subsequent cleaning work.
