Abstract
The utility model relates to improved high efficiency vacuum oil filtering equipment, belonging to mineral oil purification equipment. In order to enhance the efficiency of purification, an oil liquid atomizing dispenser 7 is arranged on the upper part of a vacuum separating tank 6, a separating tower 8 which is composed of a multilayer folding screen net with a large extended area and a plurality of partition boards which are overspread with small holes are arranged at the middle part of the vacuum separating tank 6, and the lower part of the vacuum separating tank 6 is provided with an external adjustable automatic oil level controller 15. The utility model has the advantages of easy material collection, easy manufacture, small size, and convenient moving. The utility model can be used for purifying oil in a transformer with high efficiency and speed under the condition of operating with electricity, can be singly used for vacuum injecting and exhausting oil, or can be singly used for pumping vacuum for a vacuum container.
Description
The utility model is a kind of modified high-efficiency vacuum oil filter, belongs to mineral oil cleaning equipment.
At present, the insulating oil of domestic processing transformer, capacitor, oil circuit breaker, transformer etc. mostly uses vacuum oil-filter, to remove impurity, moisture content and the gas in deoiling.Its treatment effect depends primarily on the state that oil exists, i.e. You degree of scatter, liquid form and the time of staying in vacuum separation tank.Existing vacuum oil-filter, the state that oil exists in vacuum separation tank has three kinds, i.e. column, granular and membranaceous.Changed oily liquid form owing to membranaceous, and obviously increased with degree of scatter and the time of staying of column to oil than granular, its treatment effect is better.But still exist the volume of vacuum separation tank big, and the space utilization rate variance, degree of scatter, liquid form and the time of staying of oil in vacuum separation tank is also undesirable, once filters shortcomings such as qualification rate is low, often wants repeated multiple times to handle and just can reach requirement.
The purpose of this utility model is to provide a kind of improved vacuum oil-filter, and its purified treatment duration is short, volume is little, oil level is easy to adjust, can carry out fast purification to the transformer wet goods under the situation of charging operation handles.
The utility model is made up of thick oil filter, oil-feed pump, heater, vacuum separation tank, vavuum pump, oil drain pump, smart oil filter etc., and has been equipped with corollary apparatus such as radiator valve, automatic oil level controllers.The oil atomization distributor that is covered with aperture is equipped with on the top that it is characterized in that vacuum separation tank, the knockout tower of being made up of the dividing plate of multilayer folding silk screen and the full aperture of polylith brill is equipped with at the middle part, and purpose is to increase oily degree of scatter, change oily liquid form and increase the oil time of staying in a vacuum.The oil of heater via heating enters vacuum separation tank under pressure, spray downwards by the oil atomization distributor, it is vaporific greatly to form decentralization, trickles down equably then on the folding silk screen in knockout tower upper strata, and form very thin oil film on its herringbone inclined-plane.In keeping the jar of condition of high vacuum degree, W/O part and bubble highly volatile, in addition, fluid along the inclined-plane irregular downwards when mobile with stirrings of rolling, make the fluid surface constantly obtain upgrading, and make oil flowing time prolongation in a vacuum.When by the porous barrier between two-layer folding silk screen, the sub-distribution again of getting back flows to the folding silk screen of one deck down.Because the developed area ratio of folded net increases 250% with the conventional structure of volume, therefore, repetitious like this result, increased degree of scatter and the time of staying of oil under vacuum state greatly, thereby the moisture content in the oil once just can separated and volatilize in the circulation efficiently and rapidly with gas.In addition, in the outside of vacuum separation tank the oil level self-con-tained unit is housed, its purpose is to make the pasta in the vacuum tank to be controlled at the following design attitude of orlop dividing plate of knockout tower, is in optimum state all the time to keep separating effect.The oil level control device is contained in outside the jar, adjusts very conveniently, and it is formed by sensor coil, solid-state relay with the magnetic conductor that float connects together, and directly controls oil-feed pump.When the oil level in the vacuum knockout drum was lower than design attitude, float drove magnetic conductor near sensor coil, and the solid-state relay output is connected, and oil-feed pump starts, and oil pressure is gone in the vacuum separation tank; When oil level reached design attitude, float drove magnetic conductor away from sensor coil, and the solid-state relay output disconnects, and oil-feed pump quits work, thereby makes oil level can remain at the optimum position.
The accompanying drawing drawing is described as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the outside formula oil level self-con-tained unit structural representation of the utility model vacuum separation tank.
Among the figure: 1, inlet valve, 2, thick oil filter, 3, oil-feed pump, 4, heater, 5, radiator valve 6, vacuum separation tank, 7, the oil atomization distributor, 8, knockout tower, 9, vacuum meter, 10, condenser, 11,12, vacuum valve, 13, unidirectional vacuum valve, 14, vavuum pump, 15, outside formula oil level controllers, 16, oil drain pump, 17, hydraulically-controlled one-way valve, 18, Pressure gauge, 19, smart oil filter, 20, oil circuit transfer valve, 21, overflow valve, 22, sensor coil, 23, solid-state relay, 24, lucite tube, 25, float, 26, magnetic conductor.
Describe below in conjunction with the course of work of accompanying drawing utility model.The oil inlet and outlet of the utility model and transformer is connected, start vavuum pump 14 earlier, when treating that vacuum reaches requirement, open inlet valve 1, oil-feed pump 3 will start simultaneously automatically, transformer oil to be clean is removed impurity through thick oil filter 2, boost through oil-feed pump 3 and to enter vacuum separation tank 6 after entering heater 4 heating, through 7 atomizings of fluid distributor, be sprayed onto on the folding silk screen in upper strata of knockout tower 8, the formation oil film flows downward, and distributes the back to flow to the folding silk screen of one deck down once more by the porous barrier between two-layer folding silk screen.Go down like this, up to the bottom of vacuum separation tank 6 always.Oil forms the very big oil film of developed surface through during the multilayer folding silk screen and porous barrier of knockout tower 8, and dirty and increased the time that stops under vacuum state along the winding raod footpath, and the water in the oil is effectively volatilized with gas and separates.Volatilization and isolated gasification composition, part becomes water through condenser 10 coolings, and another part is extracted out through vavuum pump 14; The oil that purifies is pooled to the bottom of vacuum separation tank 6, is extracted out by oil drain pump 16, gets back in the transformer through smart oil filter 19.In addition, when oil drain pump 16 pressure were excessive, overflow valve 21 was opened automatically, and pressure oil changes its course automatically and flows to oil inlet end, in case abnormal failure takes place.
In order to give full play to effect of the present utility model, at the inlet end of vavuum pump 14 vacuum valve 11 and 12 are housed, when closing vacuum valve 11, when opening vacuum valve 12, the air of extracting out when can be used for transformer vacuum oil in the fuel tank is used; In addition, open oil circuit change-over switch 20, when starting oil drain pump 16, can make oiling or oil well pump again separately and use.
The utility model is purified treatment efficient height not only, and simple, makes easily, does not need special producing equipment, and volume is little, conveniently moving.
