Fig. 3 is the top view of the utility model vacuum oil purifier;
Comprise among the figure: vacuum tank 1, electric cabinet 2, magnetic valve 3, heater 4, oil drain pump 5, vavuum pump 6, water storage tank 7, condenser 8, fine filter 9, coarse filter 10, check valve 11, oil-out 12 and oil-in 13.
The specific embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, the utility model provides a kind of single-stage type vacuum oil purifier, comprise: vacuum tank 1, electric cabinet 2, magnetic valve 3, heater 4, oil drain pump 5, vavuum pump 6, water storage tank 7, condenser 8, fine filter 9, coarse filter 10, check valve 11, oil-out 12 and oil-in 13; Wherein, vacuum tank 1 is communicated with vavuum pump 6, coarse filter 10 is communicated with fine filter 9, the port of export of oil drain pump 5 is oil-outs 12, and oil-in 13 is connecting the arrival end of coarse filter 10, and heater 4 links to each other with coarse filter 10, condenser 8 is communicated with water storage tank 7, electric cabinet 2 is located at the outside of vacuum oil purifier, and magnetic valve 3 is located on the condenser 8, and check valve 11 is arranged on the arrival end of fine filter 9.
In some optional embodiments, the filter medium of described fine filter 9 is honeycomb filter cores.
In some optional embodiments, the filtering accuracy of described fine filter 9 is 5 μ m.
In some optional embodiments, the filter medium of described coarse filter 10 is woven wires.
In some optional embodiments, described vacuum tank 1 is provided with liquid level valve.
The utility model is when work, extraneous fluid sucks by inlet valve, enter coarse filter filtering large granular impurity, then deliver to heater, after being heated to predetermined temperature, enter vacuum tank, by degassed element in the tank under vacuum condition, trace water in the oil is evaporated to water vapour, and the minimum gas in the oil breaks through oil film and separates out, and enters condenser by the pipeline that is contained in tank body top together, exhausted most water vapour and oil vapour are condensed into water and fluid, when having liquid storage to bleed off in the water storage tank after the work, can close first to open again and get final product, complete machine works on.
The vacuum tank inner fluid through dehydration, degassed after, be deposited in the vacuum tank bottom, and by oil drain pump fluid pressed to fine filter and carry out fine filtering, oil vessel outside outlet valve is transported to machine.The controlled liquefaction of fluid level control valve position in the vacuum tank, when the oil level of pot bottom reach a certain height, cursory meeting raises with the rising of oil level, and liquid level valve is corresponding turning down then, and flow reduces, until close, otherwise with the reduction of fluid, liquid level valve is corresponding to be opened greatly, enlargement discharge, thus the vacuum tank inner fluid is remained on certain oil level substantially.Fine filter is used for granulometric impurity in the filter oil.Filter medium is the honeycomb filter core, and it is high that this filter core has a filtering accuracy, long service life, the advantage such as easy to operate.When operating pressure surpasses rated operating pressure 0.5MPa, must clean or renew cartridge more
The power supply that the utility model uses is three-phase 380V, 50HZ; good electric control gear and protective device are arranged; interlock between heater and the magnetic valve; make when truly having fluid to flow to heater in the oil inlet pipe, could start heater, thereby prevent that heater from burning out; electric heater is divided into two groups (i.e. " one group of heating " and " two groups of heating " two groups); when opening two groups of heaters simultaneously, can make successively plugged of two groups of heaters priorities, starting current is excessive when avoiding starting shooting.When the utility model moves, the control of oil temperature is to be undertaken by the temperature controller that is contained in the heating system, its control range is 40-80 ℃, when the oil temperature in the heating system is higher than rated temperature, temperature controller can cut off heater power source automatically, when oil temperature was lower than rated temperature, automatic plugged continued heating again.
The utility model control cabinet is provided with two time relays, and the user can according to actual conditions, set the utility model stream time (0-99 hour adjustable arbitrarily).Reach the time that sets when the utility model stream time, the utility model will automatic shutdown, quits work, and wherein the KT1 time relay is used for controlling magnetic valve and heater working time; The KT2 time relay is used for controlling oil drain pump and vavuum pump working time.In practical operation can with the KT2 time than KT1 time lengthening 1 minute.The utility model also has pressure controller, and during normal operation, " pressure is normal " indicator lamp (redness) is illuminating state, and when pressure surpassed 0.4MPa, " overpressure alarm " indicator lamp (redness) was illuminating state.The utility model will autostop, illustrates that at this moment fine filter filter core stops up, at this moment should shut down more renew cartridge.
The utility model mainly is applicable in the various electric equipments processing to insulating oil and turbine oil.Can get rid of efficiently various insulating oils or be equivalent to moisture content, gas and mechanical admixture in other oils of insulating oil viscosity, thereby improve the proof voltage intensity of insulating oil, guarantee the safe operation of electric equipment.Therefore, can supply electric appliances plant, power plant, the power supply administrations such as transformer, cable, electric capacitor, voltage switch, send power transformation work area, industrial and mining enterprises that high-voltage electrical equipment is carried out vacuum purification filtration and drying out by circulating hot oil.
The large flow oil-feed of the utility model utilization with preheat fuel tank, make enter separate or filter before fluid can fully be heated and reduced viscosity, satisfy the needs of the normal net fuel of reconditioner, overcome traditional absolute oil equipment and do not satisfy the shortcoming that heavy oil is processed under normal temperature.
The utility model adopts a preheating system and an electric control system, can realize to the heating of thick oil and to the control of purification process; And with large flow high suction depth oil drain pump, preheat fuel tank, vacuum separation chamber, Double-stage rotary vane vacuum pump, filter and electrical control cabinet and be installed on the mobile trolley, whole device volume reduces relatively, conveniently moving.
For making any technical staff in this area realize or to use the utility model, the above is described disclosed embodiment.To those skilled in the art; The various alter modes of these embodiment all are apparent, and the General Principle of this paper definition also can be applicable to other embodiment on the basis that does not break away from spirit of the present disclosure and protection domain.Therefore, the disclosure is not limited to the embodiment that this paper provides, but consistent with the widest scope of the disclosed principle of the application and novel features.
