Description
Technical field
The present invention relates to a kind of molten lead device, particularly a kind of for the molten lead system to accumulator plate casting machine feed.
Background technology
Lead-acid accumulator is as one of modal battery on the market, in China and be widely used all over the world.It has voltage stabilization, low-cost advantage, although have specific energy low (being the electric energy of per kilogram accumulators store), a problem such as service life is short and regular maintenance is frequent, but along with the development of science and technology, the life-span of lead-acid accumulator becomes longer and safeguards also simpler.
The basic principle of lead-acid accumulator be when battery in when electric discharge, oxidation reaction, as negative pole, occurs in metallic lead, is oxidized to lead sulfate; Reduction reaction, as positive pole, occurs in brown lead oxide, is reduced to lead sulfate.Battery is when using charged with direct current, and the two poles of the earth generate respectively lead and brown lead oxide.Wherein both positive and negative polarity is all take the metal screen as Polar plate matrix, the metal screen is generally cast and is formed by metal, in casting process, after needing first by lead melting furnace, the metal raw material to be melted to the formation lead water, then lead water is transported in the casting equipment and casts.
Existing molten lead system generally comprises molten lead bath, charging aperture and discharging opening.wherein, existing molten lead bath generally adopts single groove heating, namely in lead melting furnace, be provided with the melting channel of a smelting lead alloy raw material, notification number is that the patent documentation of CN202158752U discloses a kind of smelting furnace, be provided with molten chamber, combustion chamber, incubation cavity and the molten chamber lid that coordinates with described molten chamber, the combustion chamber circle lid that coordinates with described combustion chamber, described combustion chamber is arranged at described outside, molten chamber and is affixed with described molten chamber, the outer peripheral of described combustion chamber is provided with incubation cavity, the chamber wall of described combustion chamber is provided with air inlet duct, described air inlet duct is connected with blower fan, the axis of described air inlet duct and the included angle A of horizontal plane are set to 40 degree to 50 degree, preferably be set to 45 degree.
In metal screen casting process, metal screen periphery has the burr that casting forms, and affects product quality and follow-up manufacturing process, need to remove this burr by methods such as punching presses.In order to save material, improve the utilization rate of material, the leftover pieces of removal can be reclaimed, again transport the lead melting furnace fusing back, existing equipment is generally to transport leftover pieces back lead melting furnace by transmission mechanism, on lead melting furnace, be provided with the leftover pieces entrance corresponding with the transmission mechanism outlet, leftover pieces enter lead melting furnace by the leftover pieces entrance.
The metal raw material is in lead melting furnace in course of dissolution, can produce a large amount of flue dust and pernicious gas, therefore, before exhaust, need to carry out dust removal process, have the researcher to propose the dust arrester that a kind of smelting furnace is used, notification number is that the patent documentation of CN2706754Y discloses a kind of smelting furnace waste gas trap, it is characterized in that above flue, connecting a cylindrical shell, at cylindrical shell external connecting one cover body, wherein, above flue, outlet is closed, and in side, evenly is provided with exhaust smoke hole; Cylindrical shell is wedge type, and its bottom is provided with dust-exhausting port; On the circumference of cover body bottom surface, evenly be provided with air admission hole, side is provided with exhaust outlet and the air-introduced machine intake stack links.Its stops useless flue gas direct soaring discharge in flue, can make larger particles dust in the flue gas cylindrical shell that sinks, and by air-introduced machine, is taken away after making the flue gas that continues to rise and air from the cover body bottom mixing, sends into once again the interior participation of body of heater second-time burning.
The metal raw material is sent in lead melting furnace from charging aperture by feed mechanism, described charging aperture is located at the lead melting furnace eminence, the lead water that fusing is arranged in lead melting furnace, when falling into lead water, the metal raw material can cause that lead water splashes, for head it off, have the researcher to propose a kind of device that makes the metal raw material slowly enter lead water, notification number is that the patent documentation of CN102721283A discloses and a kind of anti-splash device for the metal smelting furnace.Its technical scheme is: fixed mount is housed at the close outer rim place at metal smelting furnace furnace lining top and near the inner edge place, installing rack is housed.The upper end of fixed arm is fixed on the edge at metal smelting furnace inwall top, and the lower end of fixed arm is fixed on the bottom of metal smelting furnace.The upper end of lever arm is hinged on the upper end of fixed mount, during the revolution of the lower end of lever arm and the minimum clearance of metal furnace bottom be 1mm; One end of retractor device is hinged on the upper end of installing rack, and the other end and lever arm are hinged.Fixed arm, lever arm and retractor device form clamping device, and the lower end of fixed arm intersects mutually with the bottom of lever arm, and the angle of fixed arm and lever arm bottom is 20～60 °.
The lead melting furnace of existing single groove heating is simple in structure, heating is convenient, but while heating, but the metal raw material once need to be heated to casting temperature, but the lead water that outflow is simultaneously cast is less, and most of lead water is stored in lead melting furnace, due to very large with the temperature difference of environment in lead melting furnace, although be added with attemperator, heat energy loss is very fast, causes energy waste, high temperature causes the oxidation of alloy compositions in stove, volatilization to accelerate simultaneously, causes alloying component unstable.
Existing waste material recovery device in use, because lead melting furnace need to be worked under hot conditions, namely needs lead melting furnace is incubated to processing, so the opening of leftover pieces entrance is unsuitable excessive, in order to avoid affect the heat insulation effect of lead melting furnace.Simultaneously, because leftover pieces are different, easily winding-shaped becomes the metal frame that volume is larger mutually, in the situation that the opening of leftover pieces entrance is less, easily stops up the leftover pieces entrance.
The big dust particle of existing equipment in removing waste gas, namely during solid slag, although the solid slag in purifying exhaust air effectively, complex structure, and bulky, be not suitable for small-sized lead melting furnace.
Although have now and prevent that the equipment that lead water splashes from can play the problem of splashing that prevents when leady raw materials enters lead water, but, the lower end of the fixed arm that is provided with in this device intersects mutually with the bottom of lever arm, the lower end of fixed arm is fixed on the bottom of metal smelting furnace, during the lower end of lever arm revolution and the minimum clearance of metal furnace bottom be 1mm, be only applicable to the lead pig of regular shape is cushioned, if metal raw material in irregular shape, easily, with the fixed arm that intersects and lever arm generation bite, cause device to work.
