Abstract
The utility model relates to a device for cleaning furnace accretion of a lead blast furnace, comprising a steel ejector rod which is connected with the cylinder head of a hydraulic cylinder through a coupling flange. The hydraulic cylinder is arranged on a fixing base corresponding to a cupola charging door on a furnace side wall. At least one hydraulic cylinder is arranged along ambient directions of the lead blast furnace in order to accelerate the speed of furnace accretion cleaning. A centralized control mode for an oil pump station is adopted by power system, and therefore, the utility model is characterized in safety, high efficiency and automatic operation.
Description
The utility model relates to a kind of cleaning lead blast furnace accretion device, belongs to the special equipment in the pyrometallurgical smelting of lead technology in the nonferrous metallurgy field, uses when especially being fit to handle the accretion on the lead blast furnace furnace wall.
In pyrometallurgical smelting of lead technology, the incident maximum fault of lead blast furnace is that the accretion (also claiming furnace accretion) on the furnace wall forms, this because high-temperature material and blast furnace are vaporized between the cold water water jacket furnace wall because of the adhesive that a variety of causes produced, will influence the air quantity that blasts in case surpass certain thickness, and the work section of stove is dwindled gradually, furnace gas is concentrated and is risen, cause the heat top, thereby the production capacity and the plumbous rate of recovery of stove have been reduced, if do not add processing, this trend continues, will cause blowing out.Therefore, regular removing accretion is the operate as normal of lead blast furnace operation.
At present, the mode of cleaning accretion has two kinds: domestic manufacturer adopts labor cleaning's mode more, when promptly the accretion on finding the furnace wall has grown into enough greatly, elder generation's blowing out level-lowering, open the fire door of end wall again, go the end wall accretion with drill rod and big chiso-mallet, insert between accretion from the two ends fire door with rail or rod iron again, beat the rail flush end with the sledgehammer shake, make accretion collapse broken falling, this kind method cleaning accretion, inefficiency, labour intensity are big, sometimes also need the operating personnel to enter cleaning in the stove, dangerous, the gas poisoning phenomenon easily takes place; External some producer then adopts quantitatively explosion earlier, labor cleaning's mode again, promptly earlier the accretion on the furnace wall is cut a hole into several duck eyes, look accretion thickness situation then and put into explosive in right amount, after the explosion of igniting again by manually clearing up at last, though this method cleaning accretion effect is better, but need pay special attention to safety, and explosion influences service life of equipment, easily causes the body of heater distortion, also still need manually clear up at last simultaneously.
The purpose of this utility model, be to overcome the above-mentioned deficiency of prior art, by designing a kind of cleaning lead blast furnace accretion device, realized employing automation cleaning accretion, thereby alleviate labor strength, eliminated the unsafe factor that operation field exists, cleared up the accretion time simultaneously to shorten to present 2 hours, improved operating efficiency greatly by original one time 10 hours.
The device of this cleaning lead blast furnace accretion that the utility model provides, used steel push rod when including usually artificial prepurging, difference is that this steel push rod is connected with the cylinder head of hydraulic cylinder by tie-plate, this hydraulic cylinder be installed in lead blast furnace sidewall cleaning door opposite position on holder on.During the prepurging operation, after opening cleaning door, hydraulic cylinder carries out straight reciprocating motion under hydraulic oil promotes, cylinder head affects push rod directly to probe in the stove and acts on the accretion, make accretion break away from the furnace wall, pour in the furnace high-temperature molten bath and melt, for realizing goal of the invention of the present utility model better, respectively be provided with a hydraulic cylinder at least along plumbous air blast peripheral direction, the central controlled mode of oil pump station is adopted in power section.
Accompanying drawing is the embodiment that the utility model provides, and wherein Fig. 1 is the fundamental diagram of the hydraulic power system of embodiment; Fig. 2 is the monomer structure schematic diagram of embodiment.As seen from the figure, this embodiment has adopted the form that is provided with a hydraulic cylinder in the lead blast furnace peripheral direction at least, and wherein DYB-3 type oil pump station is adopted in power section, the remote installation, control mode is remote start-stop Hydraulic Station, closely manually controls the hydraulic cylinder direction of motion and length.Operation principle of the present utility model is:
During the prepurging operation, at first starting motor 1, high-low pump 2,3, start working simultaneously, Pressure gauge 8,9 shows the low-lift pump oil pressure, Pressure gauge 10 shows the high-pressure pump oil pressure, low pressure relief valve 5 is pressed by the low pressure oil cylinder pressure of setting, and high-pressure overflow valve 6 connects the hydraulic oil cylinder pressure of setting and presses, and sequence valve 4 is to electro-hydraulic reversing valve 11 fuel feeding simultaneously.Electro-hydraulic reversing valve 11 energisings start, and magnetic valve is connected low pressure oil and sent into pilot operated valve device by sequence valve 4, and pilot operated valve device is pushed into chamber, a left side (right side), hydraulic oil enters fluid pressure line, and this state because oil mass is very little, is high pressure conditions down in the pipeline, hydraulic oil has guaranteed that with low pressure check valve 7 sealings high pressure is stable.Hand-operated direction valve 12 is shifted right chamber onto, and hydraulic oil enters hydraulic cylinder 13 back cavities by hydraulic fluid port 14 and promotes cylinder head and advance, hydraulic cylinder 13 be installed in furnace sidewall cleaning door opposite position on holder on.It is the no load condition operation that hydraulic cylinder 13 begins, oil pressure reduces in the pipeline, high pressure disappears, low pressure check valve 7 is opened, high-low pump 3,2 while fuel feeding, sequence valve 4 keeps the operating oil pressure of power supply liquid reversal valve 11, hydraulic cylinder 13 advances fast, the steel push rod of handling by tie-plate 17 when the cylinder head of hydraulic cylinder 13 18 passes the furnace wall cleaning door, when leaning the accretion 19 on furnace wall steam jacket 16, need add high thrust, this moment, oil pressure raise with the required thrust increase, and hydraulic oil seals low pressure check valve 7 again, guarantee that hydraulic oil is not leaked by low pressure relief valve 5, at this moment hydraulic cylinder 13 is a high pressure duty at a slow speed.After the accretion cleaning is finished, hand-operated direction valve 12 is pulled to left chamber, hydraulic cylinder 13 is for retreating duty fast.
With the existing method ratio of removing the lead blast furnace accretion, the utility model has been realized the automation cleaning Operation has efficient, safe characteristics.
