Description
Technical Field
The utility model relates to a hydraulic tank purifier and oil tank belongs to oil purification technical field.
Background
The hydraulic oil is a hydraulic medium used by a hydraulic system utilizing hydraulic pressure energy, and plays roles of energy transfer, wear resistance, system lubrication, corrosion resistance, rust resistance, cooling and the like in the hydraulic system. If the hydraulic oil cannot be kept clean, even if tiny impurities enter the high-pressure oil, the valve body channel (pipeline) in the mechanism is blocked or jammed, so that the hydraulic device cannot work normally. Therefore, there is a high demand for the cleanliness of the hydraulic oil. In the traditional high-pressure oil filtering process, the filter screen is easy to deform and weld, and can not be reused, and the filter element is not easy to replace.
SUMMERY OF THE UTILITY MODEL
For solving the not enough of prior art, the utility model aims to provide a hydraulic tank purifier.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a hydraulic tank purifier, is fixed with the upper cover including setting up at the oil tank oil-out and stretching into the oil absorption pipe at the bottom of the oil tank on the oil tank oil-out, and the upper cover upper end is provided with out oil pipe, goes out oil union coupling hydraulic pump, its characterized in that: the oil tank oil-out is fixed with the filter core, and the filter core comprises mounting and filter screen, and the mounting is connected through the full weld mode with the filter screen.
The fixing piece is a stainless steel flange plate and is connected with the upper end of the oil tank through a screw; the filter screen is a stainless steel mat-type woven screen.
The filter screen comprises tube-shape filter screen and hemisphere type filter screen, and tube-shape filter screen and hemisphere type filter screen are connected through the full weld mode.
The oil outlet pipe is arranged on one side above the filter element.
And an oil return port is formed in the upper end of the oil tank, and a check valve is arranged in the oil return port.
The utility model has the advantages that: the filter element is arranged at the oil outlet, so that the filter element can be conveniently replaced and cleaned, and the damage caused by the long-term immersion of the filter element in the hydraulic oil is avoided; meanwhile, the filter screen and the fixing piece are connected in a full welding mode, so that the filter screen is firm and seamless, and is not easy to weld.
Drawings
Fig. 1 is an overall front view of the present invention.
Fig. 2 is a schematic diagram of the filter element structure of the present invention.
The oil tank is characterized in that 1 is an oil tank, 2 is an upper cover, 3 is a filter element, 4 is an oil outlet pipe, 5 is a flange plate, 6 is an oil return port, 7 is an oil suction pipe, 8 is a screw, 9 is a mat-shaped woven mesh and 10 is a full welding line.
Detailed Description
As shown in figure 1, the hydraulic oil purification device comprises an oil suction pipe 7 which is arranged at an oil outlet of an oil tank 1 and extends into the bottom of the oil tank 1, an upper cover 2 is fixed on the oil outlet of the oil tank, an oil outlet pipe 4 is arranged at the upper end of the upper cover 2, the oil outlet pipe 4 is connected with a hydraulic pump, a filter element 3 is fixed on the oil outlet of the oil tank 1, the filter element 3 consists of a fixing piece and a filter screen, and the fixing piece is connected with the filter screen in a full-welding mode.
The fixed part is a stainless steel flange 5 and is connected with the upper end of the oil tank 1 through a screw 8; the filter screen is a stainless steel mat-type woven mesh 9.
The filter screen comprises tube-shape filter screen and hemisphere type filter screen, and tube-shape filter screen and hemisphere type filter screen are connected through the full weld mode.
The oil outlet pipe 4 is arranged on one side above the filter element and not above the filter element, so that the falling oil is prevented from washing away impurities on the inner wall of the filter screen.
An oil return opening 6 is formed in the upper end of the oil tank, and a check valve is arranged in the oil return opening 6.
In the specific working process: when the hydraulic pump is started, oil in the hydraulic oil tank 1 flows out of the liquid suction pipe 7, then flows out of the oil outlet pipe 4 through the filter element 3 in a cavity formed by the oil tank 1 and the upper cover 2, and impurities in the hydraulic oil are filtered in the filter element 3; because the pressure in the cavities of the oil tank 1 and the upper cover 2 is higher, the filter element welded by the spot welding mode and the filter element of the common woven net are easy to deform under higher pressure, influence is caused on the filtration of hydraulic oil, and the replacement is frequent; the utility model provides a filter screen adopts the mat type to weave the filter screen through the full welding mode welding, and the structure that the filter screen comprises tube-shape filter screen and hemisphere type filter screen, not only filter area increase, and difficult deformation, need not frequent change. When the filter element is used for a period of time, the filter element is taken down and washed, and if the filter element is intact, the filter element can be continuously installed for use.
When the hydraulic pump stops working, hydraulic oil can flow back to the oil tank 1 through the oil return opening 6, and the phenomenon that impurities on the inner wall of the filter element 3 are flushed back into the oil tank by the returned oil can be avoided; a check valve is arranged in the oil return port to prevent oil in the oil tank from being directly pumped out without being filtered when the oil tank is full.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
