Description
Technical field
The utility model relates to the anti-dust storm device of the coolant air of the heating electric equipment of a kind of diesel locomotive anti-dust storm device, particularly diesel locomotive such as exciting dynamo, starting lubricating oil pump, high-low pressure cabinet.
Background technology
Equipment such as the heating electric equipment of diesel locomotive such as exciting dynamo, starting lubricating oil pump, high-low pressure cabinet, usually all be to adopt the interior air intake mode of car to cool off, owing to the more sand and dust of all having carried under one's arms from car body outside cooling air into the car, anti-dust storm device need be set at the ventilation inlet place.Present common anti-dust storm device, be a blade of louver window to be set at the ventilation inlet place of car body, there is filtering net the louver back, louver is when open mode, the outer cold wind of car carry under one's arms sand and dust through behind the blade of louver window almost be unobstructed vertical strike on filtering net, wind into the car filters the back through filtering net heat-producing device is cooled off.The strainability of existing filtering net is: wind speed is when 2m/s, and when the filter particulates diameter was not less than the dust of 50um-80um, resistance was not more than 80Pa, and filter efficiency is at 60%-70%, and dust containing capacity is 224g/m
2Therefore because the filter efficiency of filtering net is little, when locomotive is used in the serious area of dust storm, sand and dust will directly enter in the car gross pollution environment inside car greatly, increase the working service work capacity of locomotive greatly, reduced the reliability of electric equipment in the car.And the filter efficiency of this filtering net and dust capaciting ability are that the dust containing capacity of filtering net is 224g/m at northern China dust storm area design-calculated basically
2, therefore, the resistance of filtering net is easy to rise, and particularly wet resistance certainly will increase negative pressure in the car so greatly, causes diesel engine oil leak sealing wet goods problem.Secondly this anti-dust storm device does not design special dust discharge road, being filtered the sand and dust that net stops will amass in the lower area that piles up between louver and the filtering net in a large number, after the negative pressure in the car raise, the sand and dust of accumulation can be inhaled in the car, further worsen environment inside car.
The utility model content
The purpose of this utility model is: provide the big diesel locomotive of a kind of good filtration effect, dust capaciting ability anti-dust storm device.
The purpose of this utility model realizes by implementing following technical proposals Come:
A kind of diesel locomotive is prevented the dust storm device, its top is arranged on the ventilation inlet place of car body, it is characterized in that: the top of anti-dust storm device comprises the labyrinth type filtering installation that is fixed on the car body and the filtering net at rear portion thereof, the bottom of anti-dust storm device is that a hollow that communicates with top that is arranged in the car body is held the dirt district, end and car body exterior that the bevelled that appearance bottom, dirt district is provided with is arranged husky road, also be provided with sand prevention adverse current plate on Pai Shadao top, be connected with appearance dirt district sidewall around it.
