Abstract
The invention discloses accumulator plate drying technology, which is characterized in that: the middle-temperature curing technology is adopted and comprises the following steps of: a, starting a steam generator, operating a circulating fan, and starting atomizing humidification; b, preheating, feeding the accumulator plate into a curing chamber and preheating for 0.5 to 0.6 hours in the curing chamber; and c, exiting the preheating stage, directly entering a curing and drying stage, and gradually raising the temperature stage by stage so as to dry the accumulator plate until the humidity of the accumulator plate is less than 10 percent. The accumulator plate drying technology has the advantages of simple production technology, capacity of effectively solving the problem of cracks of the accumulator plate, and high popularization value.
Description
Technical field
The present invention relates to the battery technology field, embodiments of the invention relate to a kind of polar plate of lead acid storage battery drying process.
Background technology
The storage battery kind of being sold on the market is a lot of now, also is no lack of the technical scheme about storage battery in the Chinese patent literature.In general, lead acid accumulator mainly is made up of pole plate, dividing plate, cell jar lid (container), electrolyte and other parts.The electrode that pole plate is made up of the conductor grid of active material and support usefulness is divided into positive plate and negative plate.At present, the accumulator plate drying process generally is to finish in the accumulator plate drying oven, under hot environment with pole plate in moisture flash baking in the extremely short time more than 90%, though avoid accumulator plate oxidized phenomenon in surface in drying course, but because drying rate is too fast, be full of cracks often appears in accumulator plate when drying, influenced the quality of product greatly.In order to solve the problem that the accumulator plate dry run occurs, have in the prior art by pole plate is put into dilute sulfuric acid and soak drying process, though can reduce the crack number that pole plate produces, but can not tackle the problem at its root.
Summary of the invention
Purpose of the present invention is exactly that a kind of not only production technology that provides for the deficiency that solves prior art is simple, and can effectively solve the accumulator plate drying process that crackle appears in accumulator plate.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of accumulator plate drying process is characterized in that it adopts intermediate temperature setting technology, specifically comprises the steps:
A, open steam generator and operation circulating fan, atomizing humidifying performance is opened;
B, preheating are sent pole plate to curing room, curing room preheating operation 0.5～0.6 hour;
C, withdraw from warm-up phase, directly enter the curing drying stage then, progressively heat stage by stage, the humidity of pole plate is dried to below 10%.
As further specifying of such scheme, open steam generator and operation and also need water level before the circulating fan described through hydraulic pressure, compressed air pressure and the indoor little water box of checking curing room, guarantee hydraulic pressure at 0.2～0.4MPa, compressed air pressure at 0.4～0.6MPa, little water box water level and sensor distance 1～2cm.
In the warm-up phase of described step b, the temperature in the curing room is 43～47 ℃.
The curing drying stage of described step c comprises ten drying stages, and the first five stage is a cure stage, and back five stages are drying stage; Circulating fan is slowly blown in the cure stage, and be 48 hours curing time, and the temperature in each stage rises 2 ℃ successively, and the pole plate humidity of cure stage final stage is controlled at 55～60%; Drying stage drying time is 21 hours, and the pole plate humidity of final stage is controlled at 5～10%.
Behind the curing drying stage of described step c, polar board surface watermark area is greater than 9cm
3, quote the temperature dry 4～8 hours again in the final stage of drying stage.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
The present invention can effectively solve the crack performance that pole plate takes place by stage by stage pole piece being cured dried in heating process, compare with traditional processing technology, has beyond thought effect.
Embodiment
A kind of accumulator plate drying process of the present invention, it adopts intermediate temperature setting technology, specifically comprises the steps:
The start of a, curing room is prepared, and checks the water level of hydraulic pressure, compressed air pressure and the indoor little water box of curing room, guarantee hydraulic pressure at 0.2～0.4MPa, compressed air pressure at 0.4～0.6MPa, little water box water level and sensor distance 1～2cm; Check whether auxiliary steam generator machine water and electricity supply normal, open the blowdown valve blowdown after, and trial run; Check that the cloth on the transducer circulates the back cleaning once at every turn, changes gauze after two to three circulations;
B, open steam generator and operation circulating fan, atomizing humidifying performance is opened, and the steam pressure of steam generator is between 0.5～0.7;
C, preheating are sent pole plate to curing room, and the temperature in the curing room is 43～47 ℃, curing room preheating operation 0.5～0.6 hour;
D, withdraw from warm-up phase, directly enter the curing drying stage then, progressively heat stage by stage, the humidity of pole plate is dried to below 10%, wherein, solidifies drying stage and comprise ten drying stages, the first five stage is a cure stage, and back five stages are drying stage; Circulating fan is slowly blown in the cure stage, and be 48 hours curing time, and the temperature in each stage rises 2 ℃ successively, and the pole plate humidity of cure stage final stage is controlled at 55～60%; Drying stage drying time is 21 hours, and the pole plate humidity of final stage is controlled at 5～10%.As shown in the table:
Behind the curing drying stage of described step c, polar board surface watermark area is greater than 9cm
3, quote the temperature dry 4～8 hours again in the final stage of drying stage.
Above-described only is preferred implementation of the present invention, should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
