Abstract

The utility model relates to a three-level degasification and water subject vacuum tank device for automatic vacuum oil filter, which relates to a purification treatment device of transformer oil and turbine oil. Aiming at present vacuum oil filter which uses single-level degasification and water structure, and cooler is air cooling with lower purification efficiency, the utility model provides a three-level isolation vacuum separation chamber with simple structure, which is a three-level degasification and water subject vacuum tank device, the inner of the tank forms remote film moving fog type separation, therefore enhancing the purification efficiency. The technical scheme used is that inner middle and upper parts of a subject vacuum tank (9) are provided with an oil film rolling separator (8), a first pumping vacuum pipe (3)communicated with the tank wall, a second pumping vacuum pipe (4), and a third first pumping vacuum pipe (5). A cooling tank (18) is provided with an upper and middle flange (12) and a middle and lower flange (19) therein and a plurality of once pumping vacuum pipes (15) and twice pumping vacuum main pipes (14) are arranged there between.

Description

Three grades of degassings of fully automatic vacuum oil filter, water main body vacuum tank device

One, technical field

The utility model relates to transformer oil, turbine oil purifying processing device, especially three of the fully automatic vacuum oil filter grades of degassings, water main body vacuum tank device.

Two, background technology

Transformer uses certain hour, need carry out purifying treatment to transformer oil, generating set turbine oil, guarantees that main transformer, main frame normally move.The vacuum oil-filter of selling all adopts the single-stage degassing, water structure in the market, and water cooler also is air cooling, the rolling distance that exists oil film is short, diffusion area is little, harmful gas is heavier for containing in the oil, water content is 10%, this single step arrangement, and purification efficiency is low.In the patent disclosure of number of patent application 91208126.0 " a kind of vacuum oil-filter " still exist above-mentioned deficiency.

Three, summary of the invention

The purpose of this utility model provides a kind of simple in structure, and three grades of isolated vacuum separate chambers make to form the vaporific separation of rolling of long-range film in the main body jar, thereby improve three grades of degassings, the water main body vacuum tank device of the fully automatic vacuum oil filter of purification efficiency.

The technical scheme that the purpose of this utility model adopted is, by the main body vacuum tank, cooling tank is formed, its main body vacuum tank upper top device has oil-in, wall top UNICOM first step vacuum lead, middle and lower part jar inner wall device has liquid level magnetic to float transmitter, there is oil outlet following bottom, there is oil film rolling separator at interior middle and upper part of jar and middle part device respectively, the second stage vacuum lead exit end of main body vacuum tank skin middle and upper part UNICOM and a jar outer first step vacuum pipe UNICOM, the other end mouth of pipe is between two oil film rolling separators in jar, a main body vacuum tank skin middle and lower part UNICOM third stage vacuum lead exit end and a jar outer second stage vacuum pipe UNICOM, jar in the other end mouth of pipe be in a following oil film rolling separator below, the other end of oil-in is equipped with the rotary spray device, the vacuum inlet mouth of the exit end UNICOM cooling tank of first step vacuum lead, cooling tank tank skin middle and upper part and middle and lower part be cooling water outlet and entrance of cooling water respectively, the bottom jar is equipped with liquid level meter outward, there is drainage interface following bottom, be equipped with in jar and be equipped with many between central flange and the following central flange and once vacuumize cooling tube and secondary vacuum pumping main pipe line, the secondary vacuum pumping main pipe line the other end and meet vacuum-pump line UNICOM.

The utility model principle of work, need to purify transformer oil, turbine oil enters in the jar from the oil-in of main body vacuum tank, evenly spray on the two-stage oil film rolling separator at the rotary spray device, increase the rolling distance and the diffusion area of transformer oil film at three grades of separation vacuum chambers, make moisture content in the transformer oil, gas is fully spread, at this moment under the suction function that vacuumizes, three grades of different sites improve the transformer oil purification speed, make obnoxious flavour, the very fast vacuum inlet mouth from cooling tank of moisture content enters and once vacuumizes cooling tube in the cooling tank, at this moment the water port that is subjected to the water coolant effect to make the moisture content separation down concentrate on the cooling tank bottom is discharged, obnoxious flavour is up taken away through the secondary vacuum pumping main pipe line under the negative pressure of vacuum effect, has purified transformer oil and has flowed away from the oil outlet of main body vacuum tank lower bottom part.

The utility model compared with prior art has simple and compact for structurely, and fabrication and installation are convenient, and are easy and simple to handle, purification efficiency height, characteristics such as purification speed is fast.

Four, description of drawings

Further specify the utility model below in conjunction with accompanying drawing.

Accompanying drawing is the utility model sectional structure synoptic diagram.
