Multi-functional automatic universal tank-washing device

Abstract

The invention relates to an automatic universal tank-washing device for cleaning the insides of railway tank wagons, automobile transportation tank wagons and similar storage tanks or fixed containers, in particular to a multi-functional automatic universal tank-washing device which is used for washing the complete internal surface of a tank by a water column (sprayed from a nozzle) after circularly flowing a cycle through hydraulic drive and mechanical drive, belonging to the technical field of railway equipment. The device provided by the invention is used for washing the complete internal surface of the tank by the water column (sprayed from a nozzle) after circularly flowing a cycle through hydraulic drive and mechanical drive. The device is characterized in that after a washing water column horizontally rotates a cycle, a nozzle automatically rotates a certain angle so as to change the only upper / lower washing positions on a vertical surface, and after carrying out multi-cycle horizontal rotation, the nozzle rotates a cycle along the vertical surface. A water inlet pipeline, a water outlet pipeline and a bottom water absorption pipeline are concentrically fixed on a manhole fixed seat, therefore, the device is convenient to install and remove.

Description

technical field [0001] The invention relates to an automatic universal tank washer for internal cleaning of tank cars transported by railway trains, tank cars transported by automobiles and similar storage tanks or fixed containers. In particular, it is a multi-functional automatic universal tank washer through hydraulic drive and mechanical transmission, so that the water column sprayed out of the nozzle can be washed to the entire surface of the tank after a cycle. It belongs to the technical field of railway equipment. Background technique [0002] At present, the cleaning of railway oil tank cars in my country mainly adopts steam degreasing and degassing, and after the remaining oil and gas meet the relevant safety standards, the method of manually lowering the tank for cleaning and descaling is used for cleaning. The completed oil cleaning operation on the inner wall of the car requires manual labor in a dirty, poisonous, hot, and choking environment, which leads to var...

Problems solved by technology

[0002] At present, the cleaning of railway oil tank cars in my country mainly adopts steam degreasing and degassing, and after the remaining oil and gas meet the relevant safety standards, the method of manually lowering the tank for cleaning and descaling is used for cleaning. The completed oil cleaning operation on the inner wall of the car requires manual labor in a dirty, poisonous, hot, and choking environment, which leads to various occupational diseases for workers in this position. According to occupational safety and health requirements, mechanical cleaning must be used instead of manual cleaning

[0003] The well-known Chinese patents CN86208397U and CN86203719U tank washing devices can spray water in all directions, but for the drainage of the bottom of my country's railway oil tank cars, an additional equipment combination is required. The two equipments interfere with each other and affect the washing effect and efficiency.

Patents 93108890.9 and 99107331.2 describe the process scheme of tank washing. Although the tank washing device and the water pump can be synchronized, there is also the problem of mutual interference between the two devices, and the vehicle to be washed needs to be moved many times.
