Abstract

The utility model provides an oil tank of a hydraulic system of an excavator. The oil tank comprises an oil tank body composed of a tank bottom, tank walls and a top cover. The top cover is provided with a ventilating hole which is provided with an air filter. The oil tank further comprises an oil suction pipe and an oil return pipe. An upper separating plate and a lower separating plate are arranged in the oil tank body, are located between the oil suction pipe and the oil return pipe, and separate an oil tank inner cavity into two semi-cavities to separate the oil suction pipe and the oil return pipe. A filter screen is arranged on a hydraulic oil passage between the upper separating plate and the lower separating plate. A taper impeller type stirrer is arranged in the semi-cavity where the oil return pipe is located. The tip of the taper impeller type stirrer is upward, and the axis of the taper impeller type stirrer is perpendicular to the tank bottom. An oil discharge plug and a liquidometer are arranged on the oil tank body. The separating plates are arranged between the oil suction pipe and the oil return pipe so as to increase oil circulation time and oil circulation distances, improve heat dissipation effect, and enable bubbles in oil to have a longer time to be separated. Stirring of the stirrer improves upward moving speed of the bubbles, and further improves bubble separation effect.

Description

A kind of fuel tank of excavator hydraulic system

Technical field

The utility model relates to the hydraulic pressure auxiliary in a kind of excavator hydraulic system, is specifically related to a kind of fuel tank of excavator hydraulic system.

Background technique

The Oiltank structure of existing excavator hydraulic system is simple, just has merely the function of storage liquid force feed, and hydraulic oil is natural heat dissipation in fuel tank, does not have the function of good heat radiation and minimizing bubble, thereby causes hydraulic oil intensification oxidation fast, the lost of life.Hydraulic oil itself worsens rotten, and the hydraulic system reliability of operation descends.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of fuel tank of excavator hydraulic system, and it is so that all to some extent optimization of the removal of hydraulic oil heat radiation filtering effect and bubble.

In order to solve the problems of the technologies described above, the technical solution of the utility model is:

A kind of fuel tank of excavator hydraulic system, comprise by at the bottom of the case, the oil box that tank wall and top cover consist of, air hole with air filter is set on the top cover, this fuel tank also comprises fuel sucking pipe and return tube, also arrange in the oil box and the fuel tank inner chamber is divided into two and half chambeies to separate a pair of upper lower clapboard of fuel sucking pipe and return tube in the middle of being positioned at fuel sucking pipe and return tube, this is to arranging filter screen on the hydraulic oil channel between the dividing plate, return tube arranges the cone screw paddle agitator in residing half chamber, the tip of cone screw paddle agitator up and axis perpendicular to case at the bottom of, oil drain plug and level meter also are set on the oil box.

The fuel tank of above-mentioned excavator hydraulic system, described return tube enters the fuel tank from the case end stretch, and outlet end is 45° angle bending towards tank wall, towards the tank wall place of return tube outlet end permanent magnet is set.

The fuel tank of above-mentioned excavator hydraulic system, the entry end of described fuel sucking pipe arranges filter.

The fuel tank of above-mentioned excavator hydraulic system, described fuel sucking pipe also arranges butterfly valve.

In the middle of fuel sucking pipe and the return tube dividing plate is set, fuel sucking pipe and return tube are separated, increasing cycle time and the distance of oil, thus increasing heat radiation effect, and make the bubble in the oil have the long period to separate.On the hydraulic oil channel between the dividing plate filter screen is set, has increased filtering effect.Return tube arranges the cone screw paddle agitator in residing half chamber, has strengthened oily disturbance, has improved radiating effect, in addition, the stirring of stirrer improved bubble on move speed, further improved the separating effect of bubble.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the plan view after Fig. 1 dissects.

Among the figure: at the bottom of 1 the case, 2 tank walls, 3 top covers, 4 fuel sucking pipes, 5 return tubes, 6 dividing plates, 7 filter screens, 8 permanent magnets, 9 cone screw paddle agitators, 10 filters, 11 butterfly valves, 12 level meters, 13 oil drain plugs, 14 oil fillers, 15 air filters.

Embodiment

As illustrated in fig. 1 and 2, a kind of fuel tank of excavator hydraulic system, comprise by at the bottom of the case 1, the oil box that tank wall 2 and top cover 3 consist of, air hole with air filter 15 is set on the top cover, this fuel tank also comprises fuel sucking pipe 4 and return tube 5, also arrange in the oil box and the fuel tank inner chamber is divided into two and half chambeies to separate a pair of upper lower clapboard 6 of fuel sucking pipe and return tube in the middle of being positioned at fuel sucking pipe and return tube, this is to arranging filter screen 7 on the hydraulic oil channel between the dividing plate, return tube arranges cone screw paddle agitator 9 in residing half chamber, the tip of cone screw paddle agitator up and axis perpendicular to case at the bottom of, oil filler 14 also is set on the oil box, oil drain plug 13 and level meter 12.

Described return tube enters the fuel tank from the case end stretch, and outlet end is 45° angle bending towards tank wall, towards the tank wall place of return tube outlet end permanent magnet 8 is set, and has so greatly increased the oil return cross section, can prevent effectively that oil return from impacting the sludge of fuel tank bottom.Permanent magnet is set, with the metal granule to the magnetic sensitivity in the adsorbing separation fluid.

In order to keep the fluid cleaning, the entry end of described fuel sucking pipe arranges filter 10.

Described fuel sucking pipe also arranges butterfly valve 11, can adjust flux and keying fuel sucking pipe.
