Problems solved by technology

For the first method, the acid-leaching drying process will produce a large amount of dilute acid and lead mud, which consumes a lot of electric energy or heat energy. In addition, the acid-leaching process needs to increase the surface rapid drying equipment. The surface rapid drying equipment is heated by steam or electricity, and the daily operating temperature is between Above 130°C, consumes a lot of energy; for the second method, coated paper is required for the coating method, and the resistance of the battery produced is large, which affects the high-current discharge performance. In addition, the coated paper coating method is only used for lead strips It cannot be used in gravity casting plates, which account for more than 90% of the industry. Third, lead belt plates can only be cured in a stacked form. During the curing process, the internal temperature of the plates cannot be controlled, and the components of the raw plates are consistent. poor sex

preparation example Construction

[0020] The preparation technology of lead-acid battery pole plate of the present invention comprises the following steps,

[0021] S1, prepared apparent specific gravity 4.0g / cm 3 ~4.6g / cm 3 lead paste, and spread the lead paste on the grid;

[0022] S2, rolling the grid to obtain a pole plate;

[0023] S3, fixing the polar plates sequentially on the curing rack described in the first aspect of the present invention, inserting a row of polar plates into each adjacent protruding tooth 2;

[0024] S4, sending the curing frame with fixed pole plate into the curing drying room for curing.

[0025] By adjusting the specific gravity of the lead paste and setting the protruding teeth 2, the problems of sticking tape and sticking board that may exist after the acid-free leaching can be solved.

Embodiment 1

[0028] First, put in a specified amount of lead powder, sulfuric acid, water, and auxiliary materials to prepare a compound with an apparent specific gravity of 4.0g / cm 3 ~4.6g / cm 3 lead paste, and spread the lead paste on the grid;

[0029] Secondly, the grid filled with lead paste is rolled to obtain the pole plate;

[0030] Then, the rolled plate is conveyed on the conveyor belt in a single piece, the piece is picked up manually, the plate is placed vertically on the fixed frame, the plate is lifted from the bottom, and the plate is scattered along the inclined direction , so that each adjacent protruding tooth 2 of the fixing frame is inserted into a row of pole plates;

[0031] Finally, the multi-layer curing racks are stacked and sent to the curing drying room for curing.

[0032] The cost advantage of the preparation method of the present invention is:

[0033] (1) Fixture cost: Calculated on the basis of a production line: the processing fee for protruding teeth 2 ...

Abstract

The invention discloses a lead-acid storage battery plate curing frame and a preparation technology of lead-acid storage battery plates. Acid showering and rapid surface drying steps are eliminated, the efficiency is high, the energy is saved, and the cost is reduced. Pasting paper is unnecessarily employed, the preparation technology is applicable to lead tape type plates and gravity casting plates, a resistance value of a battery will not be increased, and the high current discharge performance is not influenced; the plates are not processed at high temperature, gate paste on frames and tab parts are combined well, corrosion of each part of plate gates is consistent, and the powder falling amount of three times is 40% that of the general plates; and according to the curing frame provided by the invention, the plates are non-closely cured at equal intervals, in the curing process, airflow and heat are circulated uniformly, the high temperature is not generated among the plates, and the chemical components are consistent.

Description

technical field [0001] The invention relates to the technical field of lead-acid battery pole plate preparation equipment and technology, in particular to a lead-acid battery pole plate curing frame and a preparation process thereof. Background technique [0002] At present, the production process of raw plates for lead-acid batteries includes two types: one is to apply paste to the grid first, then pour acid on the grid, and then roll it and quickly dry the surface; After the grid is pasted, it is coated with coated paper, and then rolled into the curing room for curing. For the first method, the acid-leaching drying process will produce a large amount of dilute acid and lead mud, which consumes a lot of electric energy or heat energy. In addition, the acid-leaching process needs to increase the surface rapid drying equipment. The surface rapid drying equipment is heated by steam or electricity, and the daily operating temperature is between Above 130°C, consumes a lot of ...
