Train coaling carriage freeze-proof powder spraying equipment and spraying method thereof

Abstract

The invention discloses anti-freeze powder spraying equipment for a coal loading carriage of a train and a spraying method of the anti-freeze powder spraying equipment, and belongs to the technical field of railways. The anti-freeze powder spraying equipment for the train coaling carriage comprises a support and a Roots blower, and a stock bin communicated with a feeder is arranged at the top of the feeder; dry powder nozzles are arranged at the bottoms of the rotating disc and the supporting rod; a filter screen is arranged in the stock bin, a grinding roller is arranged on the filter screen in a reciprocating mode, a filter plate is arranged at the bottom of the stock bin, a through hole is formed in the filter plate, an ejector rod is connected into the through hole in a sliding mode, and a first stirring rod and a second stirring rod which are matched with each other are rotationally connected into the stock bin; according to the invention, the dry powder is not exposed in the air during working, so that the possibility of caking of the dry powder is reduced, dust pollution caused by random drifting of the dry powder is avoided, environmental protection is more facilitated, the caked dry powder can be ground and crushed through the grinding rollers, conveying and spraying of the caked dry powder are facilitated, and the workload of later coal unloading is reduced.

Description

technical field [0001] The invention relates to the technical field of railways, in particular to an anti-freeze dry powder spraying device and a spraying method for a coal-charging carriage of a train. Background technique [0002] In order to prevent the coal from freezing in the train compartment, it is necessary to spray dry powder in the compartment before loading coal. The dry powder spraying equipment widely used in China is to transport the dry powder to the top of the compartment through a belt conveyor, and then through the rotation of an ordinary motor, Simply sprinkle the dry powder onto the carriage. The spreading effect of the dry powder on the bottom of the carriage is not optimistic. There are too many places in some places, but not in some places. In addition, the belt transmission equipment takes up a lot of space, especially in front of the electric locomotive railway, electric safety accidents are prone to occur, and the field of vision is affected near t...

Problems solved by technology

[0002]In order to prevent coal from freezing in the train compartment, dry powder needs to be sprayed in the compartment before coal is loaded. The dry powder spraying equipment widely used in China is conveyed by belt The machine transports the dry powder to the top of the compartment, and then simply sprinkles the dry powder onto the compartment through the rotation of the ordinary motor. The effect of spreading the dry powder on the bottom of the compartment is not optimistic. In some places there are too many, in some places there is no coal. Seriously, the workload of unloading coal after arriving at the port has been increased

In addition, the belt transmission equipment occupies a large space, especially in front of the electric locomotive railway, electric safety accidents are prone to occur, and the vision is affected near the railway coal loading station

The anti-freeze-dried powder is transported on the conveyor belt, and it leaks in the air. It is easy to absorb moisture and form compaction, which reduces the efficacy of the anti-freeze-dried powder. Especially in windy areas, the exposed anti-freeze-dried powder is easy to form dust pollution.
