Embodiment Construction

[0023] Such as Figure 1 to 4 Shown

[0024] The integrated filter device includes a filter 1, an oil pump 2, and a heater 3.

[0025] The filter 1 is a two-stage filter, including a housing 1a and an inner filter element. The housing 1a is generally a pipe body with upper and lower closed. The upper end of the housing 1a of the filter 1 is provided with an oil inlet 1b and The oil outlet 1g and the oil outlet 1g are located in the middle of the upper end surface of the housing 1a. The bottom of the housing 1a of the filter 1 is provided with a drainage hole 1k communicating with the outside. A valve is installed on the drainage hole 1k. The housing of the filter 1 A partition 1m is also fixed in the body 1a. The partition 1m divides the filter 1 into an upper filter cavity and a lower water collection cavity. A plurality of through holes are opened on the partition 1m to connect the filter cavity and the water collection. The structure of the filter element of the cavity is diff...

Abstract

The invention provides an integrated filtration device. The integrated filtration device comprises at least a filter; the filter is provided with an oil inlet and an oil outlet; a drain hole communicated with the outside is formed in the bottom of the filter; a tubular first filter element is nested into the filter; the filter fineness of the first filter element ranges from 2 to 5 microns; a second filter element is mounted in the first filter element; the filter fineness of the second filter element ranges from 25 to 35 microns; the oil inlet of the filter, the first filter element, the second filter element and the oil outlet are orderly combined to form a filtering oil way allowing an oil fluid to pass through. The two stages of filter elements inside the filter are integrated so that the space occupied can be reduced; besides, the filtering effect of the oil fluid after passing through the two stages of the filter elements can be improved; according to the integrated filtration device, after the oil fluid passes through the first filter element, free water in the oil fluid can be filtered while impurities in the oil fluid are filtered out, and furthermore, emulsified water in the oil fluid can be aggregated into the free water; subsequently, the oil fluid passes through the second filter element so that the left free water in the oil fluid can be filtered out; finally, water and oil in the oil fluid can be separated from each other.

Description

Technical field [0001] The invention relates to a filter device, in particular to a fuel filter device. Background technique [0002] At present, with the increasingly strict national emission regulations and the development of diesel engines in the direction of green and environmental protection, more and higher requirements are put forward for the matched diesel filters. The current diesel filter generally has the disadvantages of low filtration efficiency, poor water separation effect, and inability to independently check the internal pressure of the filter. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide an integrated filter device with reasonable structure and good water separation effect. [0004] In order to solve the above technical problems, the present invention provides an integrated filter device, which includes at least a filter. The filter is provided with an oil inlet and an oil outlet, and the bottom of the...
