Description
Technical Field
The invention belongs to the technical field of storage battery preparation, and particularly relates to a polar plate surface drying device and a polar plate preparation method.
Background
In the manufacturing process of the existing lead-acid storage battery pole plate, the pole plate is coated and filled, then passes through a compression roller, acid spraying and the like, and then enters a surface drying kiln to remove redundant moisture on the surface of the pole plate and improve the contact area of internal oxygen and external oxygen of the pole plate, so that the curing effect of the pole plate is improved, and meanwhile, the adhesion of the pole plate is reduced.
However, the surface drying kiln also has the defects that the temperature is higher and the energy consumption is high firstly because the surface moisture is removed; secondly, the temperature of the polar plate is higher after passing through the surface drying kiln, so that the water loss is faster before the polar plate enters the curing chamber for moisture preservation, and the curing effect of the polar plate is influenced; and finally, when different models are produced due to the fact that the thicknesses and the areas of the produced polar plates are not consistent, the temperature of the drying kiln needs to be reset and adjusted, and the time and the cost for model changing are increased.
In the prior art, the temperature of a drying kiln is properly reduced by improving devices such as a press roller, and the drying kiln for dropping the surface of the pole plate cannot be completely cancelled.
For example, chinese patent publication No. CN102646815A discloses a method for treating a polar plate and a press roll assembly used in the method, in which absorbent cotton yarn is wound around the press roll assembly to perform water absorption treatment on the surface of the polar plate passing through the press roll assembly. However, in the method, the water absorbing material is only wound on the compression roller assembly, the displacement is short, the water absorbing capacity is limited, and therefore, a surface drying kiln is added for drying in the follow-up process, and meanwhile, the water absorbing material of the compression roller assembly cannot be removed, so the frequency of replacing the water absorbing material is high.
Chinese patent publication No. CN 108258200A discloses a dewatering device for lead-acid battery plates, which divides a conveyor belt into a water absorption section and a drying section, wherein the water absorption section can only remove water from the upper surface of the plate, and the lower surface of the plate still needs to be dried by a drying kiln at the rear section, only the drying temperature is properly reduced, and the design of the dewatering section is complicated.
Therefore, it is desirable to design a device that has a simpler structure and can dry both sides of the plate.
