Abstract
The utility model relates to an air blower power oil cooling device, which comprises an oil tank. The utility model is characterized in that the air blower power oil cooling device also comprises a circulated cooling system, the circulated cooling system comprises a motor, a circulating oil pump and a circulating cooler, wherein the circulating oil pump is driven by the motor to achieve that oil in the oil tank is circulated between the oil tank and the cooler. Compared with the prior art, the air blower power oil cooling device has the advantages that the original cooling load discharging oil is modified to be oil tank oil which separately circulates and cools, cooling time is prolonged, cooling amount is increased, and cooling efficiency is improved, dynamic oil temperature is lowered to 20 DEF C from 55 DEG C before remodeling, and the temperature of the device requirement is greatly lowered. Normal rotation of the device is guaranteed.
Description
Technical field
The utility model belongs to metallurgical accessory, when relating in particular to the operation of a kind of blower that air blast is used in the blast furnace of smelting molten iron, the blower power oil is cooled off the device of usefulness.
Background technique
The blast furnace axial flow blower is to the key equipment of blast furnace air-supply, mainly comprises motor, blower, lubricant oil, power oil and intelligent control system etc., and it has 11 grades of variable stator vane angles, adjusts the blast pressure and the flow of blower by the angle that changes stator blade.The device that drives stator blade is two oil cylinders, and the action of oil cylinder comes work by power oil.Power oil is to provide by the power oil station, and the power oil station owner will comprise power oil pump, fuel tank, drain charge oil cooler, power motor etc.As shown in Figure 1, on the pump housing of power oil pump 2, has the drain charge oil pipe line, drain charge oil is got back to fuel tank 10 by drain charge oil cooler 4, the oil that fuel tank is 10 li arrives 3 li of oil cylinders through power oil pump 2 again, temperature improves again after the power oil pump pressurization, so circulation back power oil temperature improves gradually, if do not lower the temperature processing, blower is with regard to cisco unity malfunction.
Based on this, the defective short, that cooling effectiveness is low cool time that how to overcome existing blower power oil cooling equipment existence becomes subject matter to be solved in the utility model.
The model utility content
Goal of the invention of the present utility model is to provide a kind of cool time long, the blower power oil cooling equipment that cooling effectiveness is high.
For solving the problems of the technologies described above, the utility model is achieved by the following technical solutions:
A kind of blower power oil cooling equipment, comprise fuel tank, it is characterized in that: also comprise a circulating cooling system, described circulating cooling system comprises motor, oil circulating pump, recirculation cooler, and described oil circulating pump is realizing under the driving of motor that the oil in the fuel tank circulates between fuel tank and cooler.
Further, described oil circulating pump inlet draws a pipeline and enters in the fuel tank, and the oil circulating pump outlet links to each other with the recirculation cooler oil-in, and the recirculation cooler oil export is linked in the fuel tank with pipeline, forms a cooling circuit.
Again further, described circulating cooling system is positioned at the top of fuel tank.
Compared with prior art, advantage of the present utility model and good effect are as follows: changed into the circulation cooling separately of fuel tank oil by original cooling drain charge oil.Promptly on fuel tank, add circulation motor, oil circulating pump and a recirculation cooler, the oil circulating pump inlet draws a pipeline and enters in the fuel tank, the oil circulating pump outlet links to each other with the recirculation cooler oil-in, and the recirculation cooler oil export is linked in the fuel tank with pipeline, forms an independently cooling circuit.Prolonged cool time, improved cooling effectiveness, the power oil temperature is reduced to 23 ℃ by 55 ℃ before transforming, well below the temperature of equipment requirement.Guaranteed the normal operation of equipment.
Description of drawings
Fig. 1 is the utility model blower power oil cooling equipment system schematic representation;
Wherein, 1, power motor; 2, power oil pump; 3, oil cylinder; 4, drain charge oil cooler; 5, cooling water; 6, recirculation cooler; 7, oil circulating pump; 8, motor; 9, power oil; 10, fuel tank.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The cooling part of blower power oil is cooled off through drain charge oil cooler 4 by the drain charge oil of power oil pump 2, as shown in Figure 1, the drain charge oil of power oil pump 2 arrives drain charge oil cooler 4 by the drain charge oil pipe line, realize that therein heat displacement back arrives in the fuel tank 10, the power oil 9 that fuel tank is 10 li is antiwear hydraulic oils of Mobil, its working pressure is 12MPa, under the drive of power motor 1, power oil 9 is through power oil pump 2 pressurizations, and temperature improves, after arriving oil cylinder 3, the working environment of oil cylinder 3 reaches about 100 ℃, and power oil is through after cooling off after such circulation, during the blower operation, 55 ℃ of oil Wen Gaoda surpass the equipment allowable temperature.
In order to improve the circulation cooling effect, add an oil circulating pump 7 power oil 9 is extracted out from fuel tank 10, form an independent circulating cooling system, accelerate recirculation cooler 7 interior oil and replace with the heat of water 5.Promptly above fuel tank 10, add a motor 8, oil circulating pump 7 and recirculation cooler 6, oil circulating pump 7 inlets draw a pipeline and enter below the fuel tank 10 interior pastas, oil circulating pump 7 outlets link to each other with recirculation cooler 6 oil-ins, recirculation cooler 6 oil exports are linked in the fuel tank with pipeline, form an independently cooling circuit.
Concrete installation process is as follows: 1, choose the mounting point above fuel tank 10, oil circulating pump 7 and recirculation cooler 6 are installed, and fuel tank 10 power oil entrance and exit pipelines are connected.2, open motor 8 control circle oil pumps 7 and carry out work, flush cycle oil pump 7 and pipeline.3, on recirculation cooler 6 cooling water pipelines, be installed into flowing water Valve, connect cooling water pipeline.4, this system is installed in above the power fuel tank, opens motor and circulating water.
The utility model is through above-mentioned circulation loop, and the power oil temperature is reduced to 23 ℃ by 55 ℃ before transforming, well below the temperature of equipment requirement.Guaranteed the normal operation of equipment.Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
