Description

Technical Field

[0001] The present application relates to the technical field of railway equipment, and in particular to antifreeze liquid spraying equipment and method for railway containers. Background Art

[0002] Using railway containers to transport coal powder, mineral powder and other goods over long distances is a common method in my country. In northern China, since coal powder, mineral powder and other goods contain moisture, they often stick to the inner wall of the container during winter transportation, making it difficult to unload materials, which not only increases transportation costs but also prolongs the transportation cycle.

[0003] Spraying antifreeze in the container with appropriate spraying equipment and methods is a simple and convenient preventive measure. For open-top containers, the containers are uniformly placed on the on-track trains at the freight station, and then mobile spraying equipment is set up on both sides of the rails, or the spraying equipment is placed on a mobile trolley on the ground. The antifreeze is sprayed on the inner wall of the container by moving the spraying equipment and adjusting the nozzle angle. This is a common method used in freight stations.

[0004] The advantage of the above method is that it is easy to operate in one stop and is relatively simple to operate. However, this method is no longer applicable to end-door containers with closed roofs. For end-door containers with closed roofs, in addition to the inner wall of the roof, there are 5 walls in different directions that need to be sprayed evenly, and the spraying equipment needs to travel multiple times in different directions in the container. However, the above spraying method cannot spray end-door containers with closed roofs, and the spraying efficiency is low.

[0108] Start-up step: open the liquid supply component to provide antifreeze liquid to the spray component.

[0109] In this embodiment, the spray pressure range is set between 0.15MPa-0.50MPa, the nozzle flow range is set between 10mL / s and 40mL / s; and the moving speed of the moving component is set between 0.1m / s and 0.5m / s.

[0110] Assumptions: The dispensing pipe is parallel to the inner wall of the container to be sprayed; the distance between the nozzle and the inner wall of the container is determined by the intersection of the liquid fan of each nozzle, and the distance between the intersection and the wall is 100mm; the spray pressure range is 0.30MPa, the nozzle flow range is 25mL / s; the moving speed of the spray system is 0.25m / s.

The dumping method is adopted when unloading, and the unloading is successful in one time without adding other auxiliary measures, and there is no iron ore powder residue in the container.

[0113] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
