Detailed Description

As shown in fig. 1-7, an oil-water auxiliary separation device for an oil tank of a hydraulic generator comprises a bottom oil tank 1, wherein a separation filter device 2 is arranged in the bottom oil tank 1, a plurality of filter screens 201 are arranged in the separation filter device 2 along the length direction, the filter screens 201 separate the separation filter device 2 into a plurality of separation cavities, sealing strips 202 and magnetic plates 203 are arranged on the outer wall of the separation filter device 2, the magnetic plates 203 are used for adsorbing the inner wall of the bottom oil tank 1, the magnetic plates 203 adsorb the inner wall of the bottom oil tank 1, and a water pumping pipe 101 and a water pumping pipe 102 are arranged near the tail end of the bottom oil tank 1.

The bottom oil groove 1 is generally rectangular in section and is open at the upper end, so that the separation filter device 2 adopts the same U-shaped structure with the open upper end, a U-shaped sealing strip 202 is arranged on the outer wall of the separation filter device 2, the joint of the bottom oil groove 1 and the separation filter device 2 is sealed, because the bottom oil groove 1 is generally made of carbon steel with a rust-proof layer, a magnetic plate 203 is arranged near the sealing strip 202 to adsorb the inner wall of the bottom oil groove 1, the sealing strip 202 is compacted and compacted, and the mixed liquid is prevented from passing through the joint of the bottom oil groove 1 and the separation filter device 2.

The filter screen 201 intercepts solid impurities in the oil-water mixed solution, when the oil-water mixed solution passes through the filter screen, the flowing speed is reduced, the oil water starts to naturally delaminate, the speed is reduced to be larger than water when blocked due to the high kinematic viscosity of the oil, the passing speed is lower than that of the water, the difference is gradually increased after a plurality of times of blocking, and the oil is light in specific gravity and floats on the upper layer of the water in a concentrated manner, so that the passing rate of the separation filter device 2 to the water in unit time is high as a whole, the bottom of the tail end of the bottom oil groove 1 is provided with a drain hole and a water pumping pipe 101, and the water is rapidly discharged from the drain hole. As the oil passes slowly, the liquid level rises in the compartment, so that the water-oil layer in the height direction is more obvious, and the oil pumping pipe 102 passes through the cover of the bottom oil groove 1 from above, if the oil is dirty, the upper layer of oil can be pumped.

The inner wall of the rear end of the separation filter device 2 is provided with a pipe clamp 4 which can assist in limiting the oil pumping pipe 102.

The side wall of the water suction pipe 101 can be communicated with one upward exhaust pipe for exhausting.

In the preferred scheme, be equipped with a plurality of filter baskets 204 in the separation filter equipment 2, be equipped with in the filter basket 204 and collect the chamber, collect the chamber and be equipped with two at least filter screens 201 along fluid direction of passing, filter basket 204 is equipped with direction protruding 206 at both ends in addition, and separation filter equipment 2 inner wall is equipped with a plurality of slots 205, and direction protruding 206 is pegged graft with slot 205, and the filter screen 201 hole that arranges along fluid direction of passing reduces gradually.

The filter basket 204 upper end is equipped with the ear mount of being convenient for mention, when oil-water mixture flowed through filter basket 204, because the filter screen 201 hole that runs into earlier is big, and a large amount of solid impurity gets into the collection intracavity of filter basket 204, and the filter screen 201 of rear end is because the hole is little, and the impurity of part major diameter is stopped and is stayed in the collection intracavity. Because the filter basket 204 is provided with a plurality of filter baskets 204, different filter baskets 204 can be lifted in sequence, the filter basket 204 at the rear end is not influenced when garbage in the filter basket 204 at the front end is cleaned, or most of impurities can not flow to the rear end in a large amount because the filter basket 204 at the front end is temporarily blocked when the filter basket 204 at the rear end is cleaned.

In the preferred scheme, the tail end is equipped with the floating filter screen 3 that can slide from top to bottom in slot 205 in separation filter device 2, and floating filter screen 3 lower extreme is equipped with second cavity 302, and floating filter screen 3 side direction both ends are equipped with first cavity 301, still are equipped with on the floating filter screen 3 and place the hole, place the hole and be used for placing weight nail 5.

The frame of the floating filter screen 3 adopts engineering plastics with smaller density, the filter screen part adopts a fine metal net, and due to the cavity structure, the whole density of the floating filter screen 3 is between water and oil, and the number of the weight nails 5 is increased or decreased according to actual conditions during installation, so that the floating filter screen 3 has a certain opening degree relative to the bottom end of the separation filter device 2, and the passing efficiency of bottom water flow is quickened.

The cavity structure is sealed by a plug 303 or a jackscrew with sealant.

The oil-water separation device utilizes the density difference between water and turbine oil, then makes the turbine oil relatively move under the action of movement in the oil groove, and in the process of ascending and descending of oil liquid, the oil-water mixture continuously passes through the device, and the turbine oil containing water is filtered layer by layer under the filtration of the filter screen, so that the aim of separating oil from water is fulfilled. Only 4 devices are symmetrically arranged at the bottom of the oil tank, and accumulated water is regularly checked and discharged. The oil-water separator has good oil-water separation effect and wide application.

The above embodiments are only preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the scope of the present utility model should be defined by the claims, including the equivalents of the technical features in the claims. I.e., equivalent replacement modifications within the scope of this utility model are also within the scope of the utility model.
