Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

First embodiment

Referring to fig. 1 and 2, the present embodiment provides a hydraulic oil tank body, which includes a housing 10, the housing 10 has an inner cavity, the housing 10 is provided with an oil inlet and an oil outlet, a top plate of the inner cavity is provided with a first positioning assembly, a bottom plate of the inner cavity is provided with a second positioning assembly, the first positioning assembly and the second positioning assembly are arranged oppositely, the first positioning assembly is used for fixing an oil return filter element, and the second positioning assembly is used for fixing an oil absorption filter element.

When the hydraulic oil tank body is applied to a hydraulic oil tank, an oil absorption filter element and an oil return filter element are installed in the hydraulic oil tank body, the oil absorption filter element is installed on the second positioning assembly, and the oil absorption filter element is communicated with the oil outlet; the oil return filter core is arranged on the first positioning component and communicated with the oil inlet hole. Because first locating component installs in the roof of inner chamber, and second locating component installs in the bottom plate of inner chamber, and first locating component sets up with second locating component relatively, therefore the oil return filter core is located the top of oil absorption filter core.

Further, an oil inlet pipe 12 is installed at an oil inlet hole of the housing 10, the oil inlet pipe 12 is communicated with an oil return block 11, and the oil return block 11 is installed on the outer side wall of the housing 10. The oil entering the oil return block 11 enters the inner cavity of the shell 10 through the oil inlet pipe 12.

As shown in fig. 1 and 2, preferably, the inner cavity of the housing 10 is provided with a baffle 30, the baffle 30 divides the inner cavity into a first chamber and a second chamber, the first positioning assembly is mounted in the first chamber, the first chamber is communicated with the oil inlet, the second positioning assembly is mounted in the second chamber, the second chamber is communicated with the oil outlet, the baffle 30 is provided with a first through hole 31, and the first chamber is communicated with the second chamber through the first through hole 31. So design for fluid forms the liquid stream in first through-hole 31 department when first cavity flows to the second cavity, thereby can play the effect of defoaming. At the same time, the speed of the oil flowing into the second chamber is reduced due to the barrier of the baffle 30. In summary, the baffle 30 plays a role of defoaming and decelerating between the first chamber and the second chamber.

As shown in fig. 5, the baffle 30 is provided with a second through hole 32, and the second through hole 32 is used for the oil absorption filter element to pass through and plays a limiting role in limiting the oil absorption filter element. Specifically, the inner diameter of the second through hole 32 matches the outer diameter of the oil suction filter element, so that the oil suction filter element can pass through the second through hole 32. The distance between the baffle 30 and the bottom plate of the housing 10 is less than the height of the oil suction filter element. Because the oil absorption filter core can pass through the second through hole 32, when the oil absorption filter core and the oil return filter core are in an integrated structure, the oil absorption filter core can be extended into the second cavity from top to bottom so as to be convenient for installing the oil absorption filter core. Because the distance between the baffle 30 and the bottom plate of the shell 10 is less than the height of the oil absorption filter element, after the oil absorption filter element is installed, part of the structure of the oil absorption filter element is still located in the second through hole 32 of the baffle 30, and the second through hole 32 has a limiting effect on the oil absorption filter element.

To facilitate installation of the oil return filter element, the first positioning assembly preferably comprises a positioning cylinder 40, the positioning cylinder 40 is connected with a top plate of the inner cavity, and the positioning cylinder 40 is used for fixing the oil return filter element.

The positioning cylinder 40 is provided with an oil passing hole 41, and the oil passing hole 41 is used for communicating the central cavity of the oil return filter element with the inner cavity of the shell 10. Specifically, the oil passing hole 41 communicates the central chamber of the oil return filter element with the first chamber of the housing 10. So set up, fluid gets into a location section of thick bamboo 40 via the oilhole, and in a location section of thick bamboo 40, fluid flows into the central cavity of oil return filter core via the lateral wall of oil return filter core to it filters by the oil return filter core. The filtered oil enters the outflow positioning cylinder 40 through the oil passing hole 41 via the central chamber of the oil return filter element, and the oil flows downwards to the baffle 30, passes through the first through hole 31 at the baffle 30 and flows into the second chamber.

In order to fix the oil suction filter element, the second positioning assembly comprises an oil suction pipe 60 and a second flange 22, the oil suction pipe 60 is connected with the housing 10 through the second flange 22, the oil suction pipe 60 is communicated with the oil outlet, and the oil suction pipe 60 is communicated with the central chamber of the oil suction filter element. The oil suction filter element can be connected to the oil suction pipe 60 and also to the second flange 22, or the top of the oil suction filter element can be connected to the oil return filter element, the bottom of the oil suction filter element being limited by the oil suction pipe 60. As shown in fig. 1 and 2, preferably, one end of the oil suction pipe 60 extends into the oil outlet, and the structure that the oil suction pipe 60 extends into the inner cavity is used for limiting the position of the oil suction filter element.

Further, in order to improve the sealing performance between the oil suction pipe 60 and the oil suction filter element, the outer wall of the oil suction pipe 60 can be sleeved with a sealing ring 51, when the oil suction filter element is sleeved on the oil suction pipe 60, the sealing ring 51 is positioned between the oil suction filter element and the oil suction pipe 60, so that sealing is formed, and the oil is prevented from flowing out from the space between the oil suction filter element and the oil suction pipe 60 without being filtered by the oil suction filter element.

In a possible embodiment, the first flange 21 is arranged coaxially to the second flange 22. So set up for the oil absorption filter core after the installation also sets up with the oil return filter core is coaxial.

Of course, in another possible embodiment, the first flange 21 and the second flange 22 may not be coaxial, but the projections of the first flange 21 and the second flange 22 in the horizontal plane have an overlapping area, so that the inner diameter required for installing the oil suction filter element and the oil return filter element is relatively small. When the outer diameter of the oil suction filter element is smaller than that of the oil return filter element, the first flange 21 and the second flange 22 are preferably not coaxial, but the projection of the oil suction filter element on the horizontal plane after installation is ensured to be positioned within the projection of the oil return filter element on the horizontal plane.
