Abstract

The utility model provides a hydraulic tank with waste fitting discharging, including the oil tank body, oil tank body bottom sets up the oil extraction export, and its characteristics are: the dirty cover of installation collection on the bottom lateral surface of oil tank body, the dirty cover inner chamber of collection is through arranging oil outlet and hydraulic tank inner chamber intercommunication, and the entry end of a ooff valve is connected to the lower port that the collection was dirty, and the upper end of a dirty pipe of collection is connected to the exit end of ooff valve, and the end cap is installed to the detachable mode on the lower extreme of dirty pipe of collection. The switch valve is a normally open ball valve, and oil stains are prevented from being washed away again due to the rapid flow of hydraulic oil after entering the sewage collecting pipe, so that the cleanness of the hydraulic oil is guaranteed. When oil stain is discharged, the sewage discharge operation can be carried out without emptying hydraulic oil, and the hydraulic oil in the oil tank does not need to be emptied as long as the switch valve is closed, the plug is turned on, and the dirt is poured out. The structure is simple, the manufacturing cost is low, and the operation and the use are convenient.

Description

Hydraulic oil tank with sewage discharging device

Technical Field

The utility model belongs to the technical field of hydraulic pressure machinery, a hydraulic tank's improvement is related to, a hydraulic tank with waste fitting discharging specifically says so.

Background

The hydraulic oil tank is used for providing hydraulic oil required by work for engineering machinery, and in the working process of a hydraulic system, the hydraulic oil is continuously exchanged, and due to the fact that impurities, particles and other garbage exist in pipelines and other hydraulic devices, the hydraulic system is easy to work abnormally. In order to purify the hydraulic oil, a drain is usually installed at the bottom of the hydraulic oil tank. The existing pollution discharge device is usually an openable flange or ball valve which is closed at ordinary times, a flange cover is opened or the ball valve is opened when pollution discharge is needed, hydraulic oil of a hydraulic oil tank needs to be completely discharged before opening, the hydraulic oil is filled into the hydraulic oil tank after the discharge is finished, and the process is very inconvenient. In addition, because the sewage discharge flange or the ball valve is directly arranged at the bottom of the hydraulic oil tank, the deposited dirt or garbage is easily drawn into the hydraulic oil again under the flowing and flushing of the hydraulic oil and enters a hydraulic system.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the above-mentioned problem that prior art exists, provide a hydraulic tank with waste fitting discharging, can not be washed away once more because of the quick flow of hydraulic oil after the greasy dirt gets into waste fitting discharging, guarantee that hydraulic oil is clean, and just can carry out the blowdown operation without unloading hydraulic oil.

The utility model aims at realizing through the following technical scheme:

the utility model provides a hydraulic tank with waste fitting discharging, includes the oil tank body, oil tank body bottom sets up the oil extraction export, its characterized in that install the dirty cover of an album on the bottom lateral surface of oil tank body, the dirty cover inner chamber of collection passes through the oil extraction export with hydraulic tank inner chamber intercommunication, the lower port of the dirty cover of collection connects the entry end of a ooff valve, the exit end of ooff valve connect the upper end of an album dirty pipe 4, the end cap is installed to the detachable mode on the lower extreme of album dirty pipe.

The improvement of the technical scheme is as follows: the dirt collecting cover is conical or multi-surface conical, the upper opening end of the dirt collecting cover is connected with the bottom of the hydraulic oil tank in a sealing mode, and the caliber of the upper opening end of the dirt collecting cover is larger than that of the lower opening end.

The technical scheme is further improved as follows: the switch valve is a normally open ball valve.

The technical scheme is further improved as follows: the dirty cover of collection make an organic whole structure with corrosion resistant plate, the dirty cover of collection the upper end with the lateral surface welding of oil tank body bottom is as an organic whole.

The technical scheme is further improved as follows: the plug and the sewage collecting pipe are of an integrated structure.

The utility model has the advantages that:

the utility model discloses dirty cover of an oil extraction exit installation collection on the bottom lateral surface of oil tank body, the ooff valve that the lower port of the dirty cover of collection is connected is normally open valve, the dirty pipe lower extreme demountable installation end cap of collection that normally open valve is connected. The filth in the hydraulic oil is collected by the dirty cover of collection and is deposited to the dirt collection pipe through the normally open valve in, because the dirt collection pipe diameter is not big, and has certain length, so deposit the filth of dirt collection pipe can not get into in the hydraulic oil again. When oil stain is discharged, the switch valve is closed, the plug is turned on, and dirt is poured out without emptying hydraulic oil in the oil tank. The structure is simple, the manufacturing cost is low, and the operation and the use are convenient.

Drawings

Fig. 1 is a schematic structural diagram of the hydraulic oil tank with the dirt collecting and discharging device of the present invention.

The numbering in the figure is: 1-oil tank body, 2-dirt collecting cover, 3-switch valve, 4-dirt collecting pipe and 5-plug.

Detailed Description

The invention is described in further detail below with reference to the accompanying drawings:

referring to fig. 1, the utility model relates to an embodiment of hydraulic tank with waste fitting discharging, including oil tank body 1, set up the oil extraction export in oil tank body 1 bottom, install an album dirty cover 2 on the bottom lateral surface of oil tank body 1, the dirty cover 2 inner chambers of collection pass through oil extraction export and 1 inner chambers of hydraulic tank communicate. The lower port of the dirt collecting cover 2 is connected with the inlet end of a switch valve 3, the outlet end of the switch valve 3 is connected with the upper end of a dirt collecting pipe 4, and a plug 5 is detachably mounted on the lower end of the dirt collecting pipe 4.

Further, the dirt collecting cover 2 is conical or multi-surface conical, the upper opening end of the dirt collecting cover 2 is connected with the bottom of the hydraulic oil tank 1 in a sealing mode, and the caliber of the upper opening end of the dirt collecting cover 2 is larger than that of the lower opening end.

Preferably, the switch valve 3 is a normally open ball valve.

In actual implementation, the dirt collecting cover 2 is a conical funnel-shaped structure made of stainless steel plates, and the upper opening end of the dirt collecting cover 2 is welded with the outer side face of the bottom of the oil tank body 1 into a whole or is connected with a sealing gasket and a bolt into a whole.

Can make an organic whole structure with end cap 5 and dirty pipe 4 of collection, when tearing off end cap 5 from dirty pipe 4 of collection, still have the connecting strip to keep being connected with dirty pipe 4 of collection, end cap 5 can not drop or lose.

During the use, because ooff valve 3 is normally open, the filth in the hydraulic oil deposits the dirty pipe 4 of collection through normally open valve 3 along the lateral wall of the dirty cover 2 of hourglass hopper-shaped collection under self action of gravity, because the dirty pipe 4 diameter of collection is little, and has certain length, so, deposit the filth of the dirty pipe 4 of collection and can not get into the hydraulic oil again. When oil stain is discharged, the switch valve 3 is closed, the plug 5 is turned on, and the dirt is poured out without emptying the hydraulic oil in the hydraulic oil tank.

Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art should also belong to the protection scope of the present invention in the spirit of the present invention and the changes, modifications, additions or substitutions made therein.
