Bullet train section cleaning kerosene filtering device

The invention discloses a bullet train section cleaning kerosene filtering device which comprises a plurality of filters. The adjacent filters are connected through middle oil pipelines. Filter elements are arranged in filter shells, and the mesh numbers of the filter elements are sequentially increased. The filter with the smallest filter element mesh number is a first filter, and the first filter is connected with an external oil tank through a first oil pipeline. Each middle oil pipeline is provided with a middle pressure pump. One end of each oil pipeline is connected with the upper end ofthe filter element of the previous filter shell, and the other end of each oil pipeline penetrates through the side face of the next filter shell. The first oil pipeline is provided with a first pressure pump, and one end of the first oil pipeline is connected with the external oil tank. Impurities influencing the cleaning effect in kerosene are removed in a mode of carrying out multiple times ofpressure filtration on th
