Problems solved by technology

The disadvantages of using blower ventilation are: the mobility of the blower is poor, and it needs to consume power separately; the ventilation effect of the blower with small air volume is poor, and the operation process is unsafe; the use of compressed air ventilation causes a large consumption of compressed air, which is not good from the perspective of energy saving and cost. Economical; and the above two ventilation methods have dead corners that are not easy to ventilate in the tank, resulting in incomplete ventilation

Embodiment 1

[0014] Example 1: Connection relationship

[0015] Venturi blower 1 and flexible air intake pipe 2 are all installed on movable support 3, and compressed air telescopic pipe 4 is connected with Venturi blower 1 and pneumatic booster pump 5. Venturi fan 1 is powered by the compressed air passing through the small nozzles on its metal base to drive or accelerate the air around the flexible intake pipe 2 to generate a strong moving airflow. A hose pushed by the compressed air line connects the air supply to the inlet nozzle on the side of the fan base. The Venturi blower 1 is connected with the compressed air telescopic pipe 4, has no driving power source, is portable and movable, and its outlet directly leads into the oil tanker, and the bases all have grounding wires. The flexible inlet pipe 2 is a flexible pipeline connected between the Venturi blower 1 and the atmosphere. Before the compressed air pipeline 6, the pneumatic booster pump 5 is used to increase the intake air...

Embodiment 2

[0016] Example 2: When it is necessary to ventilate the inside of the tank, the movable bracket 3 is pushed to the vicinity of the manhole of the tanker, the Venturi blower can be held by hand, the compressed air pipeline 6 is opened, and the atmosphere connected with the flexible air intake pipe 2 is brought into the tank. 3. Venturi blower blows into the oil tanker. When the pressure is insufficient or the required ventilation in the tank is large, the pneumatic booster pump can be turned on to increase the intake pressure and increase the exhaust air volume at the outlet.

[0017] The ventilation equipment can extend into the tank at will and change the wind outlet angle, so that there is no dead angle in the tank that is not easy to ventilate.

Abstract

The invention relates to ventilating equipment for cleaning and maintenance of a railway oil tanker, particularly to portable ventilating equipment for cleaning and maintenance of the railway oil tanker. The ventilating equipment comprises a Venturi fan 1, a flexible air inlet pipe 2, a movable support 3, a compressed air telescopic pipeline 4 and a pneumatic booster pump 5. The ventilating equipment has the advantages as follows: the ventilating equipment is large in air volume, movable and portable; the ventilating equipment is not required to consume a large amount of compressed air and does not consume power; the ventilating equipment can extend into a tank at will and change the air outlet angle, so that no dead corner which is not easy to ventilate exists in the tank, and the ventilating operation is more comprehensive and thorough.

Description

technical field [0001] The invention relates to a ventilation device for cleaning and repairing railway oil tank cars, and is especially suitable for cleaning and repairing railway oil tank cars. Background technique [0002] At present, the ventilation equipment for the cleaning and maintenance of railway oil tank cars in my country adopts the following two methods: blower ventilation and compressed air ventilation. The disadvantages of using blower ventilation are: the mobility of the blower is poor, and it needs to consume power separately; the ventilation effect of the blower with small air volume is poor, and the operation process is unsafe; the use of compressed air ventilation causes a large consumption of compressed air, which is not good from the perspective of energy saving and cost. Economical; and the above two ventilation methods all have dead corners that are not easy to ventilate in the tank, resulting in incomplete ventilation. Contents of the invention ...
