Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1 and fig. 2, an embodiment of the present invention provides a switching type dual-cartridge filter, which includes an oil inlet cartridge 1 and a fine filtration cartridge 2, wherein the fine filtration cartridge 2 is provided with two sets, and is respectively located at the left and right side positions of the oil inlet cartridge 1, and is communicated with the fine filtration cartridge 2 through a flange connector 3 at the bottom.
The top of the oil inlet cylinder 1 is provided with an oil inlet 101 for entering of filtered oil, the oil inlet 101 is located at the side edge position of the oil inlet cylinder 1 and is connected through a flange interface (the universality of the flange interface can be adapted to the oil filtering connection of various mining mechanical equipment), the connection position can realize the filtering speed of 700L/min, the filtering efficiency is high, the switching valve 11 is arranged at the bottom of the oil inlet cylinder 1, the switching valve 11 is provided with an extended rod piece, the manual control operation can be facilitated, and the switching valve 11 is used for controlling the filtered oil to enter the on-off directions of the two fine filtering cylinders 2 respectively.
As shown in fig. 3, a filter element 21 is supported in the fine filter cylinder 2, and a gap is reserved between the inner wall where the filter element 21 and the fine filter cylinder 2 are located, so that when oil filter enters the fine filter cylinder 2 from the oil inlet cylinder 1 and is filtered by the filter element 21, the oil filter flows out through an oil outlet 201 arranged on the side edge. The pressure difference sending and fast filtering devices 202 are respectively arranged at the bottoms of the fine filtering cylinders 2, the pressure difference sending and fast filtering devices 202 can sense the pressure conditions in the fine filtering cylinders 2 in real time, and when the pressure reaches a preset value (namely, excessive stains possibly remained on the filter element 21 at the moment cause the increase of filtering pressure), an early warning signal is sent out through the pressure difference sending and fast filtering devices 202 to remind that the filter element 21 is replaced in time, and the filtering precision reaches 80 microns.
