Description

Technical Field

[0001] The utility model relates to the field of hydraulic stations, and in particular to an oil return filter device for a hydraulic station of an electric power system. Background Art

[0002] As an important component of mechanical equipment, the hydraulic system often has a complex and changeable working environment. The oil is easily contaminated during circulation. These pollutants may come from the wear of hydraulic components, the invasion of external impurities, and the oxidation and deterioration of the oil itself. In order to ensure the normal operation of the hydraulic system and extend its service life, the hydraulic oil must be effectively filtered and purified. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model provides an oil return filter device for a hydraulic station of an electric power system.

[0004] The technical solution adopted by this utility model:

[0005] A return oil filtering device for a hydraulic station of an electric power system comprises an oil tank and a top cover. The top cover is fixedly connected to the top of the oil tank. The right side of the bottom of the top cover is fixedly connected to an oil inlet pipe. The oil inlet pipe and the bottom of the oil tank are gap-matched. The front and rear side walls of the oil inlet pipe are gap-matched with the front and rear side walls of the oil tank. The bottom of the oil tank is fixedly connected with a plurality of lower slag pipes. The lower slag pipes are equidistantly arranged front and back. The bottom of the lower slag pipe is threadedly connected with a collecting pipe. The bottom end of the collecting pipe is fixedly connected with a turning handle. A filter plate is provided between the front and rear inner walls of the oil tank. The bottom of the filter plate is fitted with the inner bottom wall of the oil tank. Both left and right sides of the filter plate are provided with splints. The front and rear side walls of the splint are fixedly connected with the front and rear inner walls of the oil tank. The filter plate and the two splints are gap-matched. The bottom of the filter plate has filter holes. The filter holes are at the lower end of the splint. The filter plate is located on the right side of the lower slag pipe. One side of the bottom of the oil tank is inclined toward the lower slag pipe and has a slope.

[0006] The upper part of the top cover is fixedly connected to the motor, the motor is connected to the plunger pump, the plunger pump is connected to the external device, the plunger pump is connected to the bottom of the oil tank through the oil pipe, and the external device is connected to the oil inlet pipe.

[0007] The external device is an oil pump.

[0008] Beneficial effects of the utility model:

[0009] The design of the filter plate of the utility model can effectively intercept particulate impurities in the hydraulic oil, ensure the normal operation of the hydraulic system and the cleanliness of the oil, and adopt a detachable collection pipe design to make it very convenient to clean the sediment. The operator does not need to open the entire oil tank to perform maintenance work, which greatly reduces the difficulty and cost of maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] like Figure 1-7 As shown: an oil return filter device for a hydraulic station of an electric power system, comprising an oil tank 1 and a top cover 2; the top cover 2 is fixedly connected to the top of the oil tank 1, the right side of the bottom of the top cover 2 is fixedly connected to an oil inlet pipe 3, the oil inlet pipe 3 is gap-matched with the bottom of the oil tank 1, the front and rear side walls of the oil inlet pipe 3 are gap-matched with the front and rear side walls of the oil tank 1, the bottom of the oil tank 1 is fixedly connected to a plurality of lower slag pipes 4, the lower slag pipes 4 are equidistantly arranged front and back, the bottom of the lower slag pipe 4 is threadedly connected to a collecting pipe 5, the bottom end of the collecting pipe 5 A turning handle 6 is fixedly connected, a filter plate 8 is provided between the front and rear inner walls of the oil tank 1, the bottom of the filter plate 8 is fitted with the inner bottom wall of the oil tank 1, the left and right sides of the filter plate 8 are provided with clamping plates 10, the front and rear side walls of the clamping plates 10 are fixedly connected with the front and rear inner walls of the oil tank 1, the filter plate 8 is gap-fitted with the two clamping plates 10, the bottom of the filter plate 8 is provided with filter holes 9, the filter holes 9 are at the lower end of the clamping plates 10, the filter plate 8 is located on the right side of the lower slag pipe 4, and one side of the bottom of the oil tank 1 is inclined toward the lower slag pipe 4 and has a slope 15.

[0019] The upper part of the top cover 2 is fixedly connected to a motor 11 , the motor 11 is connected to a plunger pump 12 , the plunger pump 12 is connected to an external device 13 , the plunger pump 12 is connected to the bottom of the oil tank 1 through an oil pipe 14 , and the external device 13 is connected to the oil inlet pipe 3 .

[0020] The external device 13 is an oil pump.

[0021] The upper part of the top cover 2 is the power part, which includes the motor 11, the motor 11 and the plunger pump 12, etc., which are all prior art devices. The utility model only protects the structural part inside the oil tank 1.

[0022] As the hydraulic system operates, the hydraulic oil is continuously filtered through the filter plate 8, and the hydraulic oil is injected into the external device 13 through the filter plate 8 and the oil pipe 14. The filter plate 8 effectively retains the particulate impurities in the hydraulic oil on its right side, ensuring that only relatively clean hydraulic oil can continue to circulate.

[0023] As time goes by, the impurities and particulate matter accumulated on the right side of the filter plate 8 gradually increase and settle to the bottom of the oil tank 1 due to gravity. When the sediment accumulates to a certain extent, it will enter the collecting pipe 5 through the sediment lowering pipe 4.

[0024] When it is necessary to clean the sediment in the collecting pipe 5, the operator can easily unscrew the collecting pipe 5 from the lower slag pipe 4 by rotating the handle 6. At this time, the filter screen 7 in the collecting pipe 5 can be conveniently cleaned to remove impurities and particulate matter attached thereto. After cleaning, the collecting pipe 5 can be reinstalled on the lower slag pipe 4 to complete the maintenance process.

[0025] When the filter plate 8 needs to be cleaned, the top cover is opened and the filter plate 8 is pulled out to clean the filter plate 8. The present utility model only protects the mechanical part, and the functions realized by the software control part related thereto are not within the protection scope of the present utility model.
