Heating installation preheating system of car dumper

Abstract

The invention discloses a heating installation preheating system of a car dumper, and relates to the technical field of heating installation preheating. The heating installation preheating system of the car dumper comprises supports, the supports are arranged on the two sides of a railway in parallel, conveying pipes are connected to the supports through connecting devices, it can be guaranteed that the angles of the conveying pipes can be flexibly adjusted through the connecting devices, the conveying pipes are connected with spraying pipes, in order to enable the coverage range of a heating curtain to be wider, the roots of the spraying pipes are connected with rotating spraying heads, the connecting devices comprise motors fixedly connected to the inner side walls of the supports, and the output ends of the motors are connected with transmission rods. By adopting the new heating installation preheating system, the number of frozen coal of each section of wagon is effectively reduced, the dumping efficiency is further improved, and the use efficiency of the device is improved; and meanwhile, compared with an existing unfreezing measure, the new preheating system is low in investment cost, existing heating installation main pipes on site and existing consumables and spare parts of a maintenance team are utilized for manufacturing, heating equipment does not need to be additionally input, and market popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of heating preheating, in particular to a heating preheating system for a dumper. Background technique [0002] The dumper system is a very specialized bulk material unloading system, which is used for the dumping of bulk materials loaded by trains. The coal unloading system of the dumper has high unloading efficiency and less damage to the vehicle, which can improve the working environment of the on-duty personnel and facilitate the automatic control of machinery. But when the dumper is unloading coal, when the temperature is lower than minus 5°C, the coal is easy to freeze inside the wagon, making it difficult for the dumper to unload coal. At the same time, after unloading the coal, a lot of coal will freeze on the bottom of the wagon and its sides On the wall, it not only increases the loss of coal, but also increases the workload of cleaning wagons, and the unloading speed cannot meet the production de...

But when the dumper is unloading coal, when the temperature is lower than minus 5°C, the coal is easy to freeze inside the wagon, making it difficult for the dumper to unload coal. At the same time, after unloading the coal, a lot of coal will freeze on the bottom of the wagon and its sides On the wall, it not only increases the loss of coal, but also increases the workload of cleaning wagons, and the unloading speed cannot meet the production demand, which leads to difficulties in production organization during the cold winter

[0003] Most of the thawing measures in the prior art adopt a heating thawing device with the length of two gondola cars laid in the middle of the rail at the entrance of the dumper. However, the thawing range of the existing train frozen coal thawing system is too small, and the local heating preheating effect is very poor, reducing The dumping efficiency is improved, the coal unloading difficulty is improved, and the use efficiency of the device is affected. At the same time, the manpower and material resources invested in the prior art are large, the construction is difficult, and it is not economical and applicable, and it is not convenient for market promotion. The nozzle in the prior art Most of them cannot be moved, and cannot be turned over in time when the iron depot vehicles come over, which is easy to cause damage to the system and affect the safety of the device. At the same time, the nozzle connected to the nozzle cannot be rotated, which also leads to the range of heating that is sprayed out. Smaller, the thawing effect is relatively limited
