Background

In winter, when the temperature is low, particularly in northern areas, and the temperature is below zero, the dumper is easy to freeze to a container plate if loaded with water-containing goods, so that the loading and unloading are difficult, and the currently and generally adopted technical scheme is as follows: (1) tail gas heats the bottom plate of the container, (2) brushing waste engine oil to the container, and (3) spreading salt.

(1) Tail gas is used for heating a bottom plate of a cargo box, and particularly exhaust gas of a vehicle is introduced into an interlayer preset at the bottom of the cargo box through a pipeline and is heated through the temperature of tail gas of an engine, so that the cargo and the cargo box are prevented from being frozen together; however, because the specific heat capacity of the gas is small, the area of the bottom plate of the container is large, the tail gas easily dissipates heat, and the whole bottom plate is not heated in time, so that the heating is uneven.

(2) The brushing oil is used for isolating the goods from the container by forming an oil film; however, the packing box brush used oil can make the packing box inside too smooth, has the potential safety hazard, and produces the greasy dirt.

(3) Salt spreading is to prevent the goods from sticking to the box by reducing the freezing temperature of water; however, the salt spreading can cause the box plate to be corroded more easily, and the service life of the dumper is influenced.
