Compared with the prior art, the oil tank automatic heating device of the hot blast heater hydraulic station has the advantages that the device is low in cost, simple in structure, convenient to use and scientific and practical, the aging speed of a hydraulic station oil tank is lowered, operation cost is lowered, operation stability and reliability of a hot blast heater hydraulic station are improved, safe and stable operation of hot blast heater equipment is guaranteed, and normal production of a blast furnace is guaranteed.
Description
Technical field
The utility model relates to mechanical equipment technical field, particularly a kind of hot blast stove hydraulic station fuel tank automatic heating device.
Background technique
The former design of hot blast stove hydraulic station fuel tank is manual heating system, existence is heated not in time or the phenomenons such as excess Temperature of heating, when oil temperature is too low, the oil hydraulic cylinder direct changing-over stove that affects slow in one's movements, affect blast furnace air temperature, thereby affect furnace processor, the control of hot blast stove hydraulic station system fuel tank oil temperature, former design is that manual heating system is when oil temperature is lower than 25 ℃, hydraulic oil is heated, in the time that temperature is heated to 40 ℃, must stop heating, the defect that this mode of heating manually exists is: one, oil temperature is during lower than 25 ℃, heating manually not in time, cause the too low phenomenon of oil temperature, when oil temperature is too low, the oil hydraulic cylinder direct changing-over stove that affects slow in one's movements, affect blast furnace air temperature, thereby affect furnace processor, two, in hydraulic oil heating process, shut down not in time heating when hydraulic oil temperature during higher than 40 ℃, cause the too high phenomenon of oil temperature, in the time that oil temperature is too high, accelerate oil product aging, shorten the life cycle of hydraulic oil, make the operating cost of equipment increase.
Summary of the invention
The purpose of this utility model is to provide a kind of with low cost, simple in structure, fuel tank automatic heating device of improving hot blast stove hydraulic station operation stability.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of hot blast stove hydraulic station fuel tank automatic heating device, comprise fuel tank, oil circulating pump, heater, power-supply controller of electric and temperature controller, described fuel tank forms a heating circulation system by oil pipe and oil circulating pump, heater, power-supply controller of electric and temperature controller, oil circulating pump, heater, power-supply controller of electric and temperature controller are cascaded, and are connected with power supply.
Described oil circulating pump is formed by relay, contactor and oil circulating pump motor combination.
Described heater is combined by relay, contactor and heating inductor.
Described power-supply controller of electric is combined by transformer, relay and selector switch.
Described temperature controller is combined by relay and temperature detection controller.
Compared with prior art, the beneficial effects of the utility model are:
A kind of hot blast stove hydraulic station fuel tank automatic heating device, there is the features such as with low cost, simple in structure, easy to use, science is practical, slow down the aging speed of hydraulic station fuel tank, reduce operating cost, stability, the reliability of the operation of hot blast stove hydraulic station are improved, guarantee hot-blast furnace equipment safe and stable operation, thereby guaranteed the normal production of blast furnace.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model;
Fig. 2 is circuit diagram of the present utility model.
In figure: 1-fuel tank 2-temperature controller 3-oil circulating pump 4-heater 5-power-supply controller of electric 6-oil pipe.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated:
As depicted in figs. 1 and 2, a kind of hot blast stove hydraulic station of the utility model fuel tank automatic heating device, comprise fuel tank 1, oil circulating pump 3, heater 4, power-supply controller of electric 5 and temperature controller 2, described fuel tank 1 is by oil pipe 6 and oil circulating pump 3, heater 4, power-supply controller of electric 5 and temperature controller 2 form a heating circulation system, oil circulating pump 3, heater 4, power-supply controller of electric 5 and temperature controller 2 are cascaded, and be connected with power supply, oil circulating pump 3 is by relay, contactor and oil circulating pump motor combination form, heater 4 is by relay, contactor and heating inductor combine, power-supply controller of electric 5 is by transformer, relay and selector switch combine, temperature controller 2 is combined by relay and temperature detection controller.
Use when the utility model, oil under the effect of oil circulating pump 3 in the interior inflow oil pipe 6 of fuel tank 1, and on oil pipe 6 temperature controller 2, after heater 4, flow back to fuel tank 1.When oil temperature is during lower than 25 ℃, temperature controller 2 gives signal, and power-supply controller of electric 5 is selected to enter heating mode, the hydraulic oil of the heating inductor of flowing through is heated, and flow back to fuel tank.In the time that oil temperature is greater than 40 ℃, temperature controller 2 gives signal, stops the hydraulic oil of the heating inductor of flowing through to heat, and power-supply controller of electric 5 selects to enter circulation mode, so just guarantee that oil temperature fluctuates in normal range (NR) between 25 ℃ to 40 ℃, has guaranteed the normal operation of hydraulic station.
Above, be only basic principle of the present utility model, not the utility model imposed any restrictions, everyly according to the utility model, it is carried out to equivalent variations and modification, all within the category of the art of this patent protection scheme.
