Wherein the filtration system of the lube station is an essential part to ensure that a good quality lube oil is provided.

The thin oil station of the cone crusher is generally provided with five filter designs, namely oil absorption filtration, oil outlet pipeline filtration, oil return filtration, oil tank filtration and external circulation filtration, wherein the oil outlet pipeline filtration is a filtration step before lubricating oil is directly supplied to an equipment main body, and can be called core filtration of the thin oil lubrication station.

At present, an oil outlet pipeline on a thin oil station of a cone crusher is filtered by an external filter (as shown in figure 1), and the principle of the external filter is 'external inlet and internal outlet', namely lubricating oil firstly enters a filter head after being pumped out, then enters an outer cavity of the filter, and after being filtered by an intermediate filter barrel, the lubricating oil enters an inner cavity of the filter barrel, and the lubricating oil entering the inner cavity is the lubricating oil which is filtered, and then flows out of the filter through an inner cavity channel. This external configuration has significant disadvantages: (1) the external filter is generally arranged outside the lubricating station, so that a large part is added outside the lubricating station, the integrity of equipment is influenced, and inconvenience is caused during assembly, transportation, packaging or field use; (2) because the filter is arranged at the outer side of the lubricating station, a pipeline from an outlet of the pump to the filter on the lubricating station and a pipeline from the filter to the thin oil lubricating station are longer, so that the appearance is influenced, the field operation is not facilitated, and the cost is also increased; (3) the traditional external filter is designed for the purpose of lubricating oil 'external in and external out', if an internal filter is used, a connecting structure needs to be redesigned so as to facilitate the installation of the filter, facilitate the discharge of impurity sediments, facilitate the installation of a differential pressure signal transmitter and the like.
