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 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 exist than can low (i.e. the electric energy of per kilogram accumulators store), the service life short and regular maintenance problem such as frequent, but along with the development of science and technology, the life-span of lead-acid accumulator becomes longer and safeguards also simpler.
The general principle of lead-acid accumulator is that metallic lead, as negative pole, oxidation reaction occurs, is oxidized to lead sulfate when battery is when discharging; As positive pole, there is reduction reaction, be reduced to lead sulfate in brown lead oxide.Battery is when using charged with direct current, and the two poles of the earth generate lead and brown lead oxide respectively.Wherein both positive and negative polarity is all for Polar plate matrix with metal screen, metal screen is generally formed by metal casting, in casting process, need first metal raw material to be carried out after fusing forms lead water by lead melting furnace, then lead water is transported to during casting is equipped 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 to heat, namely in lead melting furnace, be provided with the melting channel of a smelting lead alloy raw material, notification number be CN 202158752 U patent document discloses a kind of smelting furnace, be provided with molten chamber, combustion chamber, incubation cavity and the molten chamber lid coordinated with described molten chamber, the combustion chamber circle lid coordinated 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 is formed, and affects product quality and subsequent manufacturing processes, needs 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 lead melting furnace fusing is transported back, existing equipment is generally transport leftover pieces back lead melting furnace by transmission mechanism, lead melting furnace is provided with and exports corresponding leftover pieces entrance with transmission mechanism, leftover pieces enter lead melting furnace by leftover pieces entrance.
Metal raw material is in lead melting furnace in course of dissolution, a large amount of flue dust and pernicious gas can be produced, therefore, needed to carry out dust removal process before exhaust, have researcher to propose a kind of dust arrester of smelting furnace, notification number be CN 2706754Y patent document discloses a kind of smelting furnace waste gas trap, it is characterized in that above flue, connect a cylindrical shell, at cylindrical shell external connecting one cover body, wherein, above flue, outlet is closed, and is evenly provided with exhaust smoke hole in side; Cylindrical shell is wedge type, is provided with dust-exhausting port bottom it; Cover body base circumference is evenly provided with air admission hole, and side is provided with exhaust outlet and air-introduced machine intake stack is connected.Its stops useless flue gas direct soaring discharge in flue, and the larger particles dust in flue gas can be made to sink cylindrical shell, and the flue gas making continuation increase with mix from the air bottom cover body after taken away by air-introduced machine, feeding body of heater interior participation second-time burning once again.
Metal raw material is sent in lead melting furnace by feed mechanism from charging aperture, described charging aperture is located at lead melting furnace eminence, the lead water of fusing is had in lead melting furnace, metal raw material can cause lead water to splash when falling into lead water, in order to head it off, have researcher to propose a kind of device making metal raw material slowly enter lead water, notification number is patent document discloses of CN 102721283 A and a kind of anti-splash device for 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 inner edge place, installing rack is housed.The upper end of fixed arm is fixed on the edge at metal interior melter walls top, and the lower end of fixed arm is fixed on the bottom of metal smelting furnace.The upper end thereof of lever arm in 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, the other end and lever arm hinged.Fixed arm, lever arm and retractor device composition clamping device, 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 structure of existing single groove heating is simple, heating is convenient, but during heating needing metal raw material to be once heated to can casting temperature, but to flow out the lead water carrying out casting less simultaneously, 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 oxidation, the volatilization acceleration of alloy compositions in stove simultaneously, causes alloying component unstable.
Existing waste material recovery device in use, because lead melting furnace needs to work under the high temperature conditions, namely needs to carry out isothermal holding to lead melting furnace, and therefore the opening of leftover pieces entrance is unsuitable excessive, in order to avoid affect the heat insulation effect of lead melting furnace.Meanwhile, because leftover pieces are different, be easily mutually wound the larger metal frame of volume, when the opening of leftover pieces entrance is less, easily blocking leftover pieces entrance.
The big dust particle in waste gas removed by existing equipment, namely during solid slag, although can solid slag effectively in purifying exhaust air, and complex structure, and bulky, be not suitable for small-sized lead melting furnace.
Although the equipment preventing lead water from splashing existing can play the problem preventing from splashing when leady raw materials enters lead water, but, the lower end of the fixed arm be 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 revolution of lever arm and the minimum clearance of metal furnace bottom be 1mm, be only applicable to cushion the lead pig of regular shape, if metal raw material in irregular shape, easily with the fixed arm intersected and lever arm generation bite, device is caused normally to work.
