Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
With reference to shown in Fig. 2, Fig. 3 and Fig. 4, the utility model provides a kind of hydraulic oil tank, comprises oil tank body, and hydraulic oil tank also comprises: open-topped pre-flock frame 1, is placed in oil tank body; Open-topped pre-flock inner housing 2, is placed in pre-flock frame 1, leaves gap 4 between the sidewall of pre-flock inner housing 2 and the sidewall of pre-flock frame 1, and the inwall of pre-flock inner housing 2 is to the sidewall slope of pre-flock frame 1; Arrange a blade 3 in pre-flock inner housing 2 by the waist, the space in pre-flock inner housing 2 is divided into upper and lower two-part by blade 3; Blade 3 comprises the oil inlet pipe 301 and flabellum 302 that are connected with the return line of fuel tank, and oil inlet pipe 301 is arranged at the middle part of blade 3 and penetrating blade 3, around the multiple flabellum 302 of arrangement around oil inlet pipe 301, leaves space between every two flabellums 302.
Blade 3 by pre-flock inner housing 2 space be divided into upper and lower two-part, the oil inlet pipe 301 of blade 3 is connected with by with the return line of fuel tank.The effect of blade 3 is passed into by hydraulic oil in pre-flock inner housing 2, then carries out reverse reflux, make Impurity deposition.The hydraulic oil entering fuel tank enters the lower space of pre-flock inner housing 2 by oil inlet pipe 301, hydraulic oil is through the effect of oil pump, and the space between flabellum 302 enters into the upper space of pre-flock inner housing.Because the inwall of pre-flock inner housing 2 is to the sidewall slope of pre-flock frame 1, through the impurity of flabellum along the inwall of pre-flock inner housing 2 to rising, then fall in the gap 4 between the sidewall of pre-flock inner housing 2 and the sidewall of pre-flock frame 1 effect realizing filtering.Hydraulic oil after pre-flock is got back in fuel tank from the opening at inner housing 2 top and the opening at frame top 1.
As the preferred set-up mode of one, the height of pre-flock frame 1 is greater than the height of pre-flock inner housing 2, and the sidewall of pre-flock frame 1 better blocks impurity, many impurity such as to make can deposit in gap 4.
Pre-flock inner housing 2 is an inverted taper tubular, the sealed bottom of pre-flock inner housing 2.Arrange pre-flock inner housing 2 structure so simple, its sidewall tilts to pre-flock frame 1, is convenient to impurity and enters into gap 4 between pre-flock inner housing and pre-flock frame along the sidewall of pre-flock inner housing.Because hydraulic oil enters into the bottom of pre-flock inner housing 2 by oil inlet pipe 301, the laggard fan page 302 crossing blade in bottom of impacting pre-flock inner housing 2 flows out outside pre-flock inner housing 2.The sealed bottom of pre-flock inner housing, for impurity screening provides a comparatively airtight space, makes impurity not poke one's nose everywhere, thus the impurity gap entered between pre-flock inner housing and pre-flock frame more.
Pre-flock frame 1 is the sealed bottom of straight-tube shape, pre-flock frame 1.The structure of this pre-flock frame is simple, and when pre-flock inner housing 2 coordinates with pre-flock frame 2, the two can be arranged by concentricity line, and the gap 4 between pre-flock inner housing and pre-flock frame is even, also very easily processes simultaneously.
The bottom of pre-flock frame 2 offers chip removal valve, the impurity of convenient timing cleaning deposition.
With reference to shown in Fig. 5, flabellum 302 is arranged in annular, the outward edge of flabellum 302 and the inwall connecting part of pre-flock inner housing.Hydraulic oil forms rotating flow through blade, the edge of flabellum and the inwall connecting part of pre-flock inner housing, ensures that hydraulic oil can flow out inner housing in the space between flabellum.
With reference to shown in Fig. 6, hydraulic oil tank of the present utility model, has installed the device of pre-flock effect additional, the impurity such as the iron filings of hydraulic element wearing and tearing generation can be filtered out timely, timing is removed by chip removal valve, reduces vicious circle wearing and tearing, increases the working life of pipeline and hydraulic element.
The utility model additionally provides a kind of excavator, comprises the hydraulic oil tank as above described in any one.
It should be noted that, this excavator is the excavator comprising above-mentioned hydraulic oil tank, and the implementation of above-mentioned hydraulic oil tank embodiment is equally applicable in the embodiment of this excavator, also can reach identical technique effect, not repeat them here.
Above-described is preferred implementation of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not departing under principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
