A locomotive sprinkler mechanism

Abstract

This application relates to the technical field of high-speed rail bogie deicing, in particular to a locomotive sprinkler mechanism, which includes a mounting plate, a sand storage assembly, a heating assembly, a sandblasting assembly and a water filter assembly; the sand storage assembly includes a sand storage inner cylinder Together with the outer sand storage cylinder, the outer wall of the inner sand storage cylinder, the inner wall of the outer sand storage cylinder and the upper surface of the mounting plate together form an accommodation cavity, a first spiral plate is fixedly embedded in the accommodation cavity, and the interior of the inner sand storage cylinder There is a first cavity inside the sand storage outer cylinder; the heating assembly includes heat transfer oil and a number of electric heating wires; the sandblasting assembly includes a discharge pipe, nozzle and air pipe; the water filter assembly includes a rotating disc, a rotating inner column and a rotating The outer cylinder, the side wall of the rotating inner column, the inner wall of the rotating outer cylinder and the upper surface of the rotating disk together form a recycling cavity, a second spiral plate is fixedly embedded in the recycling cavity, and several feeding ports are opened on the rotating disk. A number of water filtering holes are opened on the outer wall of the rotating outer cylinder; a driving part is arranged on the mounting plate. This application improves the deicing effect.

Description

technical field [0001] The present application relates to the technical field of high-speed rail bogie deicing, in particular to a locomotive spray mechanism. Background technique [0002] With the increasing number of high-speed EMUs operating in severe cold areas in northern my country and other ultra-low temperature areas, when high-speed trains are running in cold winter, the environmental wind and snow and snow accumulation on the line will cause large areas of snow to freeze in the bogie area of ​​the train. There are serious snow and ice in the parts, which brings hidden dangers to the safe operation of high-speed trains, and also increases the cost of railway maintenance. [0003] Through retrieval, Chinese patent announcement number CN109131433B discloses a method for quickly removing snow and ice from a bogie of a high-speed train with hot micro-sand jetting. In principle, a high-speed injection device is used to spray tiny sand particles into the ice, making the i...

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that there is the following defect: when the ice on the bogie is melted and removed by the sand particles, the ice water and sand particles will fall into the sand return collection bucket, although there is a filter for the return sand collection bucket. This part of the ice water will enter into the sand storage box together with the sand, because the heating belt can only heat the sand close to the inner wall of the sand storage box. , so the sand particles located in the center of the sand storage box will not be able to reach the specified temperature, and these sand particles will not be able to use their own heat to effectively melt the ice layer after being sprayed out from the nozzle, reducing the deicing effect, so it needs to be improved
