Description
Technical field
The invention belongs to storage battery production technical fields, more particularly to a kind of furnace drying method for recycling lead mud.
Background technology
Multiple processes will produce a large amount of waste water and scrap lead mud during storage battery production, and waste water also contains a large amount of lead etc.
Heavy metal, in accumulator plate smear manufacturing process, when grid is by smear head coated plate, four frames of grid can adhere to more
Remaining lead plaster, when grid drenches acid by nip drum, most of extra lead plaster, which is fallen on, connects formation lead mud in sour pond, in order to save into
This, can recycle lead mud；In lead mud contain a large amount of moisture, if directly recycle, can cause lead plaster regarding than
Weight is unstable, influences battery with two side terminals, and the aobvious acidity of lead mud, acid bigger with the volatilization of moisture, drying difficulty increases always
Add, drying temperature and drying time are required strictly, to increase the cost of recycling, seriously affect production efficiency.
Invention content
The purpose of the present invention is to provide a kind of for recycling the furnace drying method of lead mud, by by the waste water in plate coating process
It is mixed and reacts with lead mud, neutralized lead mud acid；It is big to solve existing lead mud drying difficulty, the problem of drying time length；
By mixed processing, difficulty and cost that waste water and lead mud are individually recycled are reduced, the efficiency of recycling is improved.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions：
The present invention is a kind of furnace drying method for recycling lead mud, is included the following steps：
(1) lead mud is recycled：Classify according to positive plate lead mud and negative plate lead mud to lead mud；
(2) waste water in plate coating process is collected；
(3) waste water in step (2) is mixed with the lead mud recycled in step (1)；
(4) pH value is detected after filtering：Make mixed lead mud pH value between 7-9；
(5) it is in dispersing morphology to stir lead mud to the dry shape of solid-state；
(6) lead mud is dried.
Further, in the step (2) waste water be coating machine cleaning waste water.
Further, waste water and lead mud by weight 1 in the step (3):2 mixing.
Further, it is added and step (3) identical weight into lead mud in the step (4) when lead mud pH value is less than 7
Waste water, repeat step (3).
The invention has the advantages that：
1, operating method of the present invention is easy, easily operated.
2, the present invention effectively shortens the drying time of lead mud, improves production efficiency, has saved production cost.
3, the present invention is controlled lead mud in alkaline environment by hybrid reaction, is conducive to the generation of basic lead sulphate, Neng Gouti
4BS contents in high reuse powder, are conducive to the promotion of battery cycle life.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
