2, because body of heater is airtight and pour into inert gas at the upper space of body of heater, when lead melting furnace goes out plumbous liquid, in order to ensure it is pressure-fired environment in body of heater, gas feed adjustment valve open, the pressure-fired of Pressure gauge display is remained on to furnace inner space filling with inert gas; When supplementing low temperature lead liquid in lead melting furnace, gas feed adjustment valve closing, when the pressure of inert gas is greater than the pressure-fired of permission, decompression valve door is opened and is released more than inert gas.Go round and begin again continuous operation like this, ensures that lead melting furnace runs under the environment of isolated air, avoid the generation of lead oxide, saved raw material, improve production efficiency, and do not produced lead fume, avoid and produce pollution to environment; Create useful effect and significant progress;
3, the upper liquid level gauge of closed furnace body interior, lower liquid level gauge and solid feeder have the Mersure Controler of an interlock, realize automated production completely, enter low temperature lead liquid from charging aperture and there is no rotating machinery to going out the whole production process of plumbous liquid mouth outflow high-temperature lead liquid, production process is simple, easy, easy to control, has very high practical value;
4, the plumbous liquid almost free from admixture of gained, body is purer, and the bottom operation for storage battery production has done better preparation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Detailed description of the invention
Below in conjunction with accompanying drawing, further description is done to the present invention.
As shown in Figure 1, a kind of closed from charging lead melting furnace, lead melting furnace in this example is mainly used in the plumbous liquid hot melt that the manufacture of lead-acid accumulator stereotype is, this invention is provided with charging aperture 2 and discharging opening 20 on closed furnace body 1, and discharging opening 20 is positioned at the bottom of closed furnace body 1.
Wherein, closed furnace body 1 is closed container, adopts the lead melting furnace of closed, contributes to preserving the energy in closed furnace body 1, reduces thermal loss, decrease the discharge of polluting lead fume simultaneously.
Described charging aperture 2 is positioned at the sidewall of closed furnace body 1, in order to ensure that charging is steady, charging aperture 2 is placed under minimum working face that in closed furnace body 1, plumbous liquid level allows, charging aperture 2 is communicated with by charging line 10 with solid feeder 5, charging line 10 has material inlet 16, between material inlet 16 and charging aperture 2, has one group of raw material heating device 13.
Owing to there being one group of raw material heating device 13 on charging line 10, control raw material lead by temperature controller 12 and a temperature probe 14 and enter in closed furnace body 1 from the soft low temperature lead liquid that becomes from hard to soft, again, low temperature lead hydraulic control is built in about 150 degree; In the stage of solid feeder 5 feeding, making Solid Lead push extruding heat distortion through solid feeder 5 becomes low temperature lead liquid to enter in closed furnace body 1, by becoming from soft the principle that low temperature lead liquid is full of pipeline, avoiding charging aperture and entering air, reaching lead melting furnace completely closed.
When the supplementary lead of needs, feed ram 21 contracting of solid feeder 5 front end is returned to minimum position, and after lead enters from material inlet 16, feed ram 21 promotes lead along charging line 10 and moves ahead and the duct section entering raw material heating device 13 place.
Closed furnace body 1 top comprises an inert gas air inlet 6, be fixed on the sidewall of closed furnace body 1, be placed on maximum allowable height that in closed furnace body 1, plumbous liquid level allows, described air inlet 6 and inert gas conveyer 9 pipeline connection, inert gas conveyer 9 ensures to be pressure-fired in closed furnace body 1; This example preferred nitrogen, cost is low, effective, and cost performance is higher.Plumbous liquid in closed furnace body 1 contact with air due to the isolated of inert gas, therefore oxidation reaction does not occur, and avoids the generation of lead oxide, thus decreasing pollution and waste, and inert gas also plays the effect of the inner and outer air pressure balancing closed furnace body 1.When lead melting furnace goes out plumbous liquid, in order to ensure it is pressure-fired environment in body of heater, gas feed adjustment valve 19 is opened, the pressure-fired shown to furnace inner space topping up to Pressure gauge 22; When in lead melting furnace supplement low temperature lead liquid time, gas feed adjustment valve 19 is closed, when the pressure of inert gas is greater than the pressure-fired of permission, decompression valve door 17 open release more than inert gas.Go round and begin again continuous operation like this, ensures that lead melting furnace runs under the environment of isolated air, avoid the generation of lead oxide, save raw material, improve production efficiency, and do not produce lead fume, avoid and pollution is produced to environment, create useful effect and significant progress.
Described closed furnace body 1 sidewall also comprises and gos deep into furnace interior, the upper liquid level gauge 3 measuring molten lead liquid level and lower liquid level gauge 4, liquid level gauge can use conventional liquid level sensor, upper liquid level gauge 3, lower liquid level gauge 4 and solid feeder 5 have the Mersure Controler 18 of an interlock, when the liquid level of liquid 11 plumbous in stove drops to the position lower than lower liquid level gauge 4, solid feeder 5 is started working, and sends in closed furnace body 1 by solid lead by material inlet 16 through raw material heating device 13 preliminarily softened, post liquefaction; When the liquid level in closed furnace body 1 goes back up to the position higher than upper liquid level gauge 3, solid feeder 5 quits work, and now, completes the circulation of a job, ensures that lead melting furnace can continuous circulation work all the time, and does not occur dry stove and full stove phenomenon in closed furnace body 1.By the effect of upper liquid level gauge 3, lower liquid level gauge 4 and solid feeder 5, make melting furnace can self-feeding, avoid artificial when adding plumbous material, workman with plumbous expect directly to contact, eliminate labour, protect the healthy of workman simultaneously.
Described body of heater heater 7 is spirally wound on closed furnace body 1, controls plumbous liquid in body of heater run under certain high temperature by temperature controller 8 and a temperature probe 15, and the stereotype produced in lead-acid battery is poured into a mould general temperature and controlled at about 300 degree.
The raw material heating device 13 that the present invention includes, body of heater heater 7 are preferably induction coil, are electromagnetic controller for controlling the heating controller 8,12 of induction coil.As shown in Figure 1, induction coil controllability is good, and energy-conserving and environment-protective.Except the mode of the present embodiment heating devices heat, conventional mode of heating also can use, such as traditional heat exchange pattern, electrothermal tube etc.
Furnace bottom of the present invention, body of heater adopt exotic material cast to form, and bell adopts high-alumina brick to be built into.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
