The invention will now be described, by way of example, with reference to the accompanying drawings, in which:

fig. 1 is a schematic structural diagram of the present invention.

Wherein: the device comprises a first box body 1, a second box body 2, a partition plate 3, a through hole 4, an oil inlet 6, an air filter 7, a blow-down valve 8, a baffle plate 9, an oil pump 11, an oil return opening 10, an oil return filter 12, an oil return cavity 13, a main oil cavity 14 and a liquid level meter 5.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. The figures are simplified schematic diagrams illustrating the basic structure of the invention in a schematic way only, and therefore they show only the components relevant to the invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to be referred must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "provided", "connected", and the like are to be construed broadly, such as "connected", which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the two components can be directly connected or indirectly connected through an intermediate medium, the two components can be communicated with each other inside, the fixed connection can be welding, gluing and the like, and for those skilled in the art, the specific meaning of the terms in the present invention can be understood according to specific situations.

As shown in fig. 1: a hydraulic oil tank comprises a first tank body 1 and a second tank body 2, a partition plate 3 is connected between the first tank body 1 and the second tank body 2, a plurality of through holes 4 are arranged on the partition plate 3, a filter screen is arranged on the through holes 4, an oil inlet 6 is arranged at the top end of the first box body 1, an air filter 7 is arranged on the oil inlet 6, the bottom of the first box body 1 is a conical surface which is convex downwards, the bottommost end of the conical surface is provided with a drain valve 8, a baffle plate 9 is arranged in the second box body 2, an oil return opening 10 and an oil pump 11 are arranged at the top of the second box body 2, the oil return port 10 is connected with an oil return filter 12, the first box body 1 is communicated with the second box body 2 through a through hole 4 on the partition plate 3, carry out the first filtration through air cleaner, carry out the second filtration through the filter screen, prevent that the greasy dirt from blockking up the oil pump, the baffle highly be less than also the minimum liquid level of fluid in the oil tank.

Preferably, the baffle plate divides the second box body 2 into an oil return cavity 13 and a main oil cavity 14, the oil return cavity 13 is communicated with the main oil cavity 14, the oil return port 10 is positioned above the oil return cavity 13, and the oil pump 11 is positioned above the main oil cavity 14.
