Description

Material thawing device for locomotive carriage

Technical Field

The utility model belongs to metallurgical material transportation field, concretely relates to locomotive carriage material thawing apparatus.

Background

Train transportation is one of the main modes for bulk material transportation in the industries of metallurgy, electric power and the like. In severe cold winter, the material can be frozen when the water content in the material is too high or rain and snow are encountered during transportation, and the material is frozen on the bottom plate and the side plates of the carriage in severe cases, so that unloading is very difficult. The production of enterprises is influenced, and a large amount of manpower and material resources are consumed. And the waiting time for unloading is too long, so that the penalty for overtaking the railway stop is caused, and the logistics cost of enterprises is increased.

The traditional thawing mode, especially northern enterprises, mostly adopt a specially-built thawing warehouse, after a carriage is pulled to be put in the warehouse, the air in the thawing warehouse is integrally heated by external heat sources (such as infrared rays, steam, electricity and the like), and then the carriage is heated by hot air or is integrally heated by radiation and the like, so that frozen materials are thawed. Specifically, the method includes a hot air natural convection unfreezing mode, a hot air forced unfreezing mode and a far infrared radiation heating unfreezing mode. However, the thawing warehouse has large investment and difficult maintenance, not only has long thawing time, low operation efficiency and large energy consumption, but also is not suitable for regions which have short thawing period but cannot avoid the thawing period in the south.

There are also methods of adding ice melting agent before or in the material in the carriage, but this method is suitable for railway department or shipment department, and is not suitable for the end user who receives the material.
