Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery electrode plate manufacturing technology, specifically relating to a novel bidirectional air-inlet electrode plate curing device. Background Technology

[0002] In the production process of lead-acid battery plates, after coating, the plates need to be cured in a curing chamber. The main purpose of plate curing is to improve the mechanical strength and electrical performance of the plates. This is achieved by placing the coated plates under specific temperature and humidity conditions, promoting the hardening of the lead paste and the stability of the active material structure. This process includes the oxidation of free lead, the crystallization of basic lead sulfate, and the bonding between the grid and the active material. Controlling temperature and humidity is crucial during curing, which is typically divided into two stages: the initial stage uses low temperature and high humidity conditions to promote lead oxidation and the formation of 3BS (3PbO·PbSO4·H2O); the later stage increases the temperature to accelerate drying. Curing significantly improves plate performance, enhancing hardness and mechanical strength, preventing cracking; reducing free lead content, preventing active material shedding; promoting the recrystallization of basic lead sulfate, increasing the initial battery capacity; and simultaneously generating lead oxide through grid corrosion, enhancing bonding strength.

[0003] The existing curing chamber structure, which adopts a one-way air intake, one-way steam, and one-way atomized water replenishment structure, is not suitable for the current electrode plate stacking method. Because the electrode plates are stacked too densely, it causes uneven air velocity, temperature and humidity inside the curing chamber, resulting in large differences in the performance of the electrode plates after curing, and a high rate of failure in electrode plate moisture content and free lead content. Utility Model Content

[0004] This invention focuses on improving the structure of the curing device. The main body of the curing device adopts a two-way air intake structure on both sides, the steam adopts a two-way air intake structure on both sides at the bottom, and the atomization water replenishment also adopts a two-way water replenishment device on both sides. The subsequent drying process adopts a dehumidification system to solve the aforementioned problems.

[0005] According to one aspect of the present invention, a novel bidirectional air-inlet plate curing device is provided, comprising a main housing and a secondary housing disposed above the main housing. The top of the main housing is provided with a first interlayer cavity and a second interlayer cavity. Air inlet pipes are respectively provided on both sides inside the main housing, and an air intake is provided on the top. The secondary housing is provided with an air inlet chamber, an air outlet chamber, and a circulating fan connected to the air outlet chamber. The air inlet chamber is connected to the air inlet pipe through the first interlayer cavity, and the air outlet chamber is connected to the air intake through the second interlayer cavity.

[0006] Thus, the airflow enters the main housing through the air inlet chamber, the first interlayer cavity, and the air inlet pipe, and then exits the curing device through the air intake, the second interlayer cavity, and the air outlet chamber, completing the airflow circulation of the curing device as a whole.

[0007] In some embodiments, there are two air outlet chambers, one on each side of the air inlet chamber. The air inlet chamber has an air inlet at its top, and the air outlet chamber has an air outlet at its top. An intake fan is installed at the air inlet, and an exhaust fan is installed at the air outlet. Thus, airflow enters through the air inlet and exits through the air outlet, with the intake fan pressurizing the airflow and the exhaust fan facilitating smoother airflow discharge.

[0008] In some embodiments, the air inlet duct is composed of interconnected vertical and horizontal ducts. The vertical duct is connected to the first interlayer cavity, and the horizontal duct is provided with multiple exhaust ports. The airflow in the air inlet duct can be discharged into the main housing through the exhaust ports.

[0009] In some embodiments, the vertical pipe is formed by a fixed connection of an interconnected trapezoidal pipe and a rectangular pipe, with the trapezoidal pipe and the rectangular pipe having the same cross-sectional area at the connection point. Specifically, the end of the trapezoidal pipe with the larger area is connected to the first interlayer cavity, and the end with the smaller area is fixedly connected to the rectangular pipe, with the cross-sectional area of ​​the smaller end being equal to that of the rectangular pipe; the trapezoidal pipe is also lined with thermal insulation cotton.

[0010] In some embodiments, the main housing is also equipped with a steam pipe that connects to the air intake chamber. Thus, after an external steam generator is connected to the steam pipe, steam enters the air intake chamber to heat and humidify the air. The heated and humidified airflow can then enter the main housing through the air intake pipe to regulate the temperature and humidity inside the main housing.

[0011] In some embodiments, atomizing water replenishment devices are also provided on both sides of the interior of the main housing, and a water replenishment tank and a water replenishment pipeline are connected to each other on the exterior of the main housing. The water replenishment pipeline is connected to the atomizing water replenishment devices. Thus, water in the water replenishment tank reaches the atomizing water replenishment device through the water replenishment pipeline, and is then sprayed into the main housing in an atomized state by the atomizing water replenishment device to help regulate the temperature and humidity inside the main housing.

[0012] In some embodiments, the two side walls of the main housing are respectively provided with wall support rods, walls, and wall insulation cotton attached to the walls from the outside to the inside. The wall support rods are fixedly connected to the top and bottom of the main housing, respectively, and are either attached to the walls or have gaps. The air inlet pipe is attached to the wall insulation cotton or has gaps.

[0013] In some implementations, a temperature and humidity sensor is also installed inside the main enclosure to monitor the temperature and humidity inside the main enclosure in real time.

[0014] In some implementations, the main housing is also equipped with a vertical lifting door, and an electric lifting machine is provided on the outer side of the top of the main housing. The electric lifting machine drives the vertical lifting door to move up and down vertically along the track to open and close the main housing.

[0015] In some implementations, the secondary housing is also equipped with an observation door for observing the internal operation of the secondary housing.

[0016] Thus, the air intake chamber, the first interlayer cavity, and the air intake pipes located on both sides of the main body form a two-way air intake system; the steam pipes, the air intake chamber, the first interlayer cavity, and the air intake pipes located on both sides of the main body simultaneously form a two-way steam system; the water supply tank, the water supply pipeline, and the atomizing water supply devices located on both sides of the main body form a two-way atomizing water supply system; and the air intake, the second interlayer cavity, and the air outlet chamber form a dehumidification system.

[0017] The curing device provided by this utility model has a main housing equipped with a two-way air intake system, a two-way steam system, a two-way atomization water replenishment system, and a dehumidification system. The auxiliary housing has a built-in circulating fan, air inlet, air outlet, and PLC electrical control system. It can solve the problem of uneven wind speed, temperature and humidity inside the curing device, ensure the consistency of the performance of the plate after curing, meet the technical requirements and quality control requirements, improve the situation of excessive moisture content and free lead content of the plate, improve grid corrosion, reduce battery capacity decay, and better control product quality.

This achieves the purpose of controlling the airflow, humidity, and temperature inside the main housing 100. A temperature and humidity sensor 18 is fixedly installed on one side of the main housing 100 to monitor the temperature and humidity inside the main housing 100 in real time.
