Description

TECHNICAL FIELD

[0001] The present application relates to the field of railway equipment, in particular to a railway container anti-freezing liquid spraying device. BACKGROUND

[0002] It is a common way to transport coal powder and ore powder over a long distance by using railway containers in China. In northern areas, the phenomenon of adhesion between goods and the inner wall of the container often occurs when transporting coal powder and ore powder containing water in winter, which causes difficulty in unloading the material, increases the transportation cost, and prolongs the transportation cycle.

[0003] Spraying anti-freezing liquid in the container and adopting appropriate spraying equipment and methods are simple and convenient preventive measures. For open-top containers, the containers are uniformly placed on the on-track train at the freight station, and then a mobile spraying device is set up on both sides of the track, or the spraying device is placed on a mobile trolley on the ground, and the anti-freezing liquid is sprayed into the container wall by moving the spraying device and adjusting the nozzle angle, which is a common method used at freight stations.

[0004] The above method has the advantages of being convenient for one-stop operation and relatively simple operation, but it is no longer applicable to closed-top end-face open-door containers. For closed-top end-face open-door containers, in addition to the inner wall of the roof, there are five wall surfaces in different directions that need to be uniformly sprayed, and the spraying device needs to travel multiple strokes in the container in different directions. However, using the above spraying method, it is not possible to spray the closed-top end-face open-door container, and the spraying efficiency is low.

Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0042] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0043] As used herein, the term "and / or" includes any one and any combination of the associated items.

[0097] In this embodiment, the spraying pressure range is set to be between 0.15 MPa and 0.50 MPa, the nozzle flow range is set to be between 10 mL / s and 40 mL / s, and the moving speed of the moving assembly is set to be between 0.1 m / s and 0.5 m / s.

[0098] Suppose that the distribution pipe is parallel to the inner wall surface of the container to be sprayed, the distance between the nozzles and the inner wall surface of the container is determined according to the intersection point positions of the liquid fan surfaces sprayed by the nozzles, the distance between the intersection points and the wall surface is 100 mm, the spraying pressure range is 0.30 MPa, the nozzle flow range is 25 mL / s, and the moving speed of the spraying system is 0.25 m / s.

[0100] After the above-mentioned method is used for spraying, since the transported iron ore in the container is a kind of water-containing iron ore, the sprayed anti-freezing liquid is a kind of organic anti-freezing liquid, the anti-freezing liquid is uniformly distributed on the inner wall of the container, and the iron ore stays at a temperature of-17℃ to-25℃ from loading to unloading for more than 48h. When unloading, the dumping method is used, and under the condition that no other auxiliary measures are taken, the first unloading is successful, and there is no iron ore powder residue in the container.

[0101] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
