In view of this, the inventor is studied this, develops specially a kind of conduction oil anti-oxidation protection device.This case produces thus.
Summary of the invention
The purpose of this utility model is to provide a kind of high-order storagetank tank anti-oxidation protection device of heat-conducting oil furnace, prevents that conduction oil is exposed in air for a long time oxidized, thereby extends the service life of conduction oil.
To achieve these goals, solution of the present utility model is:
Conduction oil anti-oxidation protection device; comprise the PLC Programmable Logic Controller; and the compression indicator, blow off valve, air inlet valve, breathing valve etc. that are arranged on the high-order storagetank of heat-conducting oil furnace tank top; the high-order storagetank tank of heat-conducting oil furnace is connected with the unreactable gas tank by blow off valve, air inlet valve; compression indicator is connected with the input end of PLC Programmable Logic Controller, and blow off valve, air inlet valve and breathing valve are connected with the mouth of PLC Programmable Logic Controller respectively.
Above-mentioned compression indicator is electro connecting pressure gauge, has three signal ends: signal common port, upper limit pressure signal end and threshold pression signal end, its upper and lower limit pressure can be regulated.
As preferably, between the high-order storagetank tank of above-mentioned breathing valve and heat-conducting oil furnace, also be provided with a hand valve.
During above-mentioned fender guard operation; first manually open air inlet valve; unreactable gas in the unreactable gas tank is pressed into to the high-order storagetank tank of heat-conducting oil furnace by air inlet valve; air in this groove tank is discharged by the top breathing valve; to the low pressure limit position; compression indicator feeds back to the PLC Programmable Logic Controller by pressure signal, by the PLC Programmable Logic Controller, automatically closes breathing valve.Start Heat-transfer Oil Pump, conduction oil enters high-order storagetank tank, and when groove tank internal pressure surpasses upper limit, compression indicator feeds back to pressure signal the PLC Programmable Logic Controller again, and PLC Controlled by Programmable Controller blow off valve, push back inertial gas tank by unreactable gas; When conduction oil is drained the oil, groove tank internal pressure is during lower than lower limit, and compression indicator feeds back to the PLC Programmable Logic Controller by pressure signal, PLC Controlled by Programmable Controller air inlet valve, unreactable gas is pressed into to high-order storagetank tank automatically by inertial gas tank, stops during to upper pressure limit.Can automatically control the pressure of the unreactable gas in high-order storagetank tank according to the oil level in high-order storagetank tank by said apparatus, prevent conduction oil exposed to air in high-order storagetank tank, thereby reach the purpose of conduction oil anti-oxidation protection.
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
The accompanying drawing explanation

The conduction oil anti-oxidation protection device mounting structure schematic diagram that Fig. 2 is the present embodiment.
Label declaration:
Blow off valve 1; Air inlet valve 2; Compression indicator 3; Heat-transfer Oil Pump 4; Breathing valve 5; Hand valve 6; Liquidometer 7; Delivery valve 8; The high-order storagetank tank 9 of heat-conducting oil furnace; Unreactable gas tank 10; PLC Programmable Logic Controller 11.
The specific embodiment
As shown in Figure 1-2; conduction oil anti-oxidation protection device; comprise PLC Programmable Logic Controller 11; and the compression indicator 3, blow off valve 1, air inlet valve 2, breathing valve 5 etc. that are arranged on the high-order storagetank tank of heat-conducting oil furnace 9 tops; the high-order storagetank tank 9 of heat-conducting oil furnace is connected with unreactable gas tank 10 by blow off valve 1, air inlet valve 2; compression indicator 3 is connected with the input end of PLC Programmable Logic Controller 9, and blow off valve 1, air inlet valve 2 and breathing valve 5 are connected with the mouth of PLC Programmable Logic Controller 9 respectively.
In the present embodiment, above-mentioned compression indicator 3 is electro connecting pressure gauge, has three signal ends: signal common port, upper limit pressure signal end and threshold pression signal end, its upper and lower limit pressure can be regulated.
Also be provided with a hand valve 6 between the high-order storagetank tank 9 of above-mentioned breathing valve 5 and heat-conducting oil furnace, because the gas only export but no import of discharging by breathing valve 5, when breathing valve 5 et out of order, can be closed by hand valve 6, prevent that extraneous air from entering the high-order storagetank tank 9 of heat-conducting oil furnace.
During above-mentioned fender guard operation; first manually open air inlet valve 2; unreactable gas in unreactable gas tank 10 is pressed into to the high-order storagetank tank 9 of heat-conducting oil furnace by air inlet valve 2; air in this groove tank is discharged by top breathing valve 5; to the low pressure limit position; compression indicator 3 feeds back to PLC Programmable Logic Controller 11 by pressure signal, by PLC Programmable Logic Controller 11, automatically closes breathing valve 5.Start Heat-transfer Oil Pump 4, conduction oil enters high-order storagetank tank 9, and when groove tank internal pressure surpasses upper limit, compression indicator 3 feeds back to pressure signal PLC Programmable Logic Controller 11 again, PLC Programmable Logic Controller 11 is controlled blow off valve 1, and unreactable gas is pushed back to inertial gas tank 10; When conduction oil is drained the oil by the delivery valve 8 of the high-order storagetank tank of heat-conducting oil furnace 9 bottoms, groove tank internal pressure is during lower than lower limit, compression indicator 3 feeds back to PLC Programmable Logic Controller 11 by pressure signal, PLC Programmable Logic Controller 11 is controlled air inlet valve 2, unreactable gas is pressed into to high-order storagetank tank 9 automatically by inertial gas tank 10, stops during to upper pressure limit.The high-order storagetank tank of heat-conducting oil furnace 9 sides also are provided with liquidometer 7, for observing the conduction oil liquid level in the groove tank.Can automatically control the pressure of the unreactable gas in high-order storagetank tank 9 according to the oil level in high-order storagetank tank by said apparatus, prevent the interior conduction oil exposed to air of high-order storagetank tank 9, thereby reach the purpose of conduction oil anti-oxidation protection.
