Abstract
The invention discloses a process for producing lead powder by utilizing lead slag produced by a lead smelting furnace. The lead slag produced by the lead smelting furnace is processed through a ball-milling method, and before the lead slag is fed into a ball-milling machine, a hammer type smashing device is used for hammering and grinding the lead slag to enable weight of a single lead slag block to be smaller than or equal to 50g. The lead slag produced by the lead smelting furnace is processed through the ball-milling method, so that the lead slag subjected to ball milling can be utilized again, the production cost is reduced, and environment pollution is reduced.
Description
Technical field
The present invention relates to a kind of technique of utilizing the lead skim production lead powder of lead melting furnace generation.
Background technology
The raw material that lead-acid accumulator mainly uses in process of production are metallic lead (pb) and plumbous alloy, and lead is the metal of grey, is period 6 the 4th main family element of the Mei Jieliefu periodic table of elements, and atomic number is 82, and relative atomic weight is 207.21.Fusing point is 327.43 degrees centigrade; Lead has that density is large, hardness is little, fusing point is low, Buddhist point is high, ductility is good, volatile under high temperature, in the large characteristics of liquid current downflow.Exactly because plumbous fusing point hangs down the manufacturing process in lead-acid accumulator production process, need to be controlled at plumbous (pb) and metal thereof between 430 ℃～550 ℃, therefore can produce a large amount of lead skims on the surface of lead melting furnace in process of production, lead skim belongs to solid waste need to send the professional treatment processed in units, the lead skim solid waste namely increases the processing cost of enterprise in operation process like this, can produce certain pollution to environment again.
Summary of the invention
Technical problem to be solved by this invention just is to provide provides a kind of technique of utilizing the lead skim production lead powder of lead melting furnace generation, and lead skim is utilized again, reduces production costs, and reduces the pollution to environment.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of technique of utilizing the lead skim production lead powder of lead melting furnace generation, it is characterized in that: the lead skim that lead melting furnace is produced utilizes ball-milling method to process, before lead skim enters ball mill, with hammer type crushing equipment, lead skim is beaten grinding and make monolithic lead skim weight≤150g.
As preferably, described lead skim is the lead skim that electrolytic lead, high purity lead, cast welding produce with plumbous fusing with lead or cast panel.
As preferably, every day lead skim addition≤ball mill output 3%, on average add interval time in proportion.
As preferably, adopt oblique elevator that lead skim is promoted to feed inlet of globe mill.
The present invention utilizes ball-milling method to process the lead skim that lead melting furnace produces, because lead skim is the product (the lead skim impurity that namely produces is less) of producing under plumbous liquid high temperature, but the volume of some money slag is larger, for guaranteeing that lead skim enters ball-grinding machine smoothly, before lead skim enters ball-grinding machine, use hammer type crushing equipment, first it is beaten grinding, make monolithic lead skim weight≤150g, the lead skim after ball milling is utilized again, reduce production cost, reduced the pollution to environment.
The specific embodiment
A kind of technique of utilizing the lead skim production lead powder of lead melting furnace generation, the lead skim that lead melting furnace is produced utilizes ball-milling method to process, and before lead skim enters ball-grinding machine, uses hammer type crushing equipment, first it is beaten grinding, makes monolithic lead skim weight≤150g.
Wherein, described lead skim is that the lead skim of plumbous fusing generation is used in electrolytic lead, high purity lead, cast welding with lead or cast panel.Every day lead skim addition≤ball mill output 3%, on average add interval time in proportion.(for example: day production capacity is the lead-power machine of 24 tons, and every day, the addition of lead skim was≤24 tons * 3%=0.72 ton, and the mode that adds is for per hour on average adding 24 hours=0.03 ton lead skim of 0.72 ton of ÷.）
Adopt oblique elevator that lead skim is promoted to feed inlet of globe mill.
Claims (4)
1. technique of utilizing lead skim that lead melting furnace produces to produce lead powder, it is characterized in that: the lead skim that lead melting furnace is produced utilizes ball-milling method to process, before lead skim enters ball mill, with hammer type crushing equipment, lead skim is beaten grinding and make monolithic lead skim weight≤150g.
2. the technique of utilizing lead skim that lead melting furnace produces to produce lead powder according to claim 1 is characterized in that: described lead skim is the lead skim that electrolytic lead, high purity lead, cast welding produce with plumbous fusing with lead or cast panel.
