Tank Cleaning Device for Special Vehicles

Abstract

The invention discloses a special vehicle in-tank cleaning device. The special vehicle in-tank cleaning device comprises a shell. An opening is formed in one side of the shell. A dust collecting device, a wiping device and a spraying device are arranged in the shell. The dust collecting device is used for sucking out impurities attached to the inner wall of a vehicle tank. The spraying device comprises a plurality of atomizing nozzles and used for spraying absolute ethyl alcohol to the inner wall of the vehicle tank. The wiping device comprises a wiping shaft installed at the opening of one side of the shell. Silk broadcloth is wound on the wiping shaft. The wiping shaft rotates to drive the silk broadcloth to wipe the inner wall, where the absolute ethyl alcohol is sprayed, of the vehicle tank. According to the special vehicle in-tank cleaning device, the problems of bristle dropping, secondary pollution, potential safety hazards and the like occurring during the traditional cleaning process are effectively solved through the work procedures such as dust removing, wiping and recovering. The work efficiency is greatly improved and the cleaning quality requirement is met.

Description

technical field [0001] The invention relates to a cleaning device inside a special vehicle tank. Background technique [0002] After the tanks of special vehicles are degreased with alkali, pickled and passivated, and dried, in order to prevent dust, sundries in the air and pollution caused by instrument debugging, it is necessary to clean the tanks with absolute ethanol before sealing them. Cleaning is the last link before the container comes into contact with the medium, which has a fatal impact on the safety of the medium. [0003] The traditional cleaning method is to wear protective equipment, carry absolute ethanol and silk cloth into the tank for wiping. There are four problems: one is the friction between the silk cloth and the metal surface, which is prone to damage, thread hanging, hair loss, and pollution. The second is that the silk cloth rubs against the metal surface for a long time. The metal surface is more likely to lose electrons and become positively cha...

AI Technical Summary

Problems solved by technology

There are four problems: First, the friction between the silk cloth and the metal surface is prone to damage, thread hanging, hair loss, and pollution

The second is that the silk cloth rubs against the metal surface for a long time. The metal surface is more likely to lose electrons and become positively charged. The positively charged metal surface is easy to absorb dust and fine fluff.

The third is that the wiping efficiency is low. The wiping effect varies depending on the operator, and there will be dead spots. For the cleaning of the top of the tank with a large diameter, auxiliary tools are needed, which increases the difficulty of the operation and increases the probability of secondary pollution.

Fourth, in the process of manual wiping and cleaning, a large amount of anhydrous ethanol volatilizes, which is very prone to alcohol poisoning of workers
