Abstract
Description
Technical Field
[0001] This invention relates to the field of curing chambers, and particularly to a curing chamber for lead-acid battery plates. Background Technology
[0002] The curing process of lead-acid battery plates is a critical step in battery manufacturing. After the plate paste is applied, it needs to be cured in an environment with specific temperature, humidity, and oxygen concentration to promote the oxidation of metallic lead in the paste and form a stable three-dimensional network crystal structure. This process directly determines the strength, porosity, and ultimately the capacity and lifespan of the battery.
[0003] Traditional curing chambers typically employ static placement or unidirectional airflow, resulting in uneven temperature and humidity distribution and incomplete curing reactions. When electrodes are stacked, airflow struggles to effectively penetrate the gaps between them, leading to significant differences in the curing environment at different locations and poor product quality consistency. Summary of the Invention
[0004] This invention provides a lead-acid battery plate curing chamber, which can solve the problem in the prior art where airflow is difficult to effectively penetrate the gaps between plates during plate stacking and curing.
[0005] A lead-acid battery plate curing chamber includes a curing chamber with a curing cavity formed therein. A first cavity and a second cavity are formed at the top and bottom of the curing chamber, respectively. A second porous plate and a first porous plate are respectively disposed at the bottom and top of the curing cavity. A first air inlet / outlet structure and a second air inlet / outlet structure are respectively disposed within the first cavity and the second cavity. The first air inlet / outlet structure and the second air inlet / outlet structure are respectively connected to a drive system, and during use, the first air inlet / outlet structure and the second air inlet / outlet structure alternately serve as the air inlet and air outlet. A double-leaf sealing door is provided on the open side of the curing cavity.
[0006] Furthermore, the drive system includes a circulating fan, which is connected to a first air inlet / outlet structure via a first pipe and to a second air inlet / outlet structure via a second pipe; a processing box is provided on the first or second pipe, and an atomizing humidification unit, an oxygen replenishment unit, and a heating unit are provided inside the processing box.
[0007] Furthermore, the first and second air inlet / outlet structures are identical in structure, each including a main pipe, with several parallel secondary pipes connected to one side of the main pipe, and several through holes opened along the length of the secondary pipes on their outer sides.
[0008] Furthermore, a vertical pipe is connected to the through hole, and a flared structure is connected to the end of the vertical pipe; the wide end of the flared structure of the first air inlet / outlet structure faces downward, and the wide end of the flared structure of the second air inlet / outlet structure faces upward.
[0009] Furthermore, openings are provided at the ends of the first cavity and the second cavity, and a first drawer structure and a second drawer structure are respectively provided in the first cavity and the second cavity; the first drawer structure and the second drawer structure are equipped with a covering structure that can controllably cover the wide end of the flared mouth structure.
[0010] Furthermore, the first drawer structure and the second drawer structure are identical in structure, both including a rectangular frame that passes through an opening. A fixed end plate is attached to one side of the rectangular frame, and a handle is provided on the outer side of the fixed end plate. A sealing layer is provided on the inner wall of the end plate. First support beams are respectively provided on the opposite side walls of the first cavity, and second support beams are respectively provided on the opposite side walls of the second cavity. The rectangular frame is supported on the upper surface of the first / second support beams. A first limiting beam and a second limiting beam are respectively provided on the inner and outer back surfaces of the first and second cavities to detect the insertion position of the first and second drawer structures. When the first and second drawer structures are inserted into the first and second cavities respectively, the end face of the rectangular frame abuts against the first or second limiting beam. A first pressure sensor and a second pressure sensor are respectively provided on the first or second limiting beam.
[0011] Furthermore, the number and position of the covering structure and the horn-shaped structure are matched one-to-one; The two adjacent covering structures are connected by a first connecting rod, and the two covering structures at both ends are respectively connected to the inner wall of the rectangular frame by a second connecting rod.

Detailed Implementation
[0018] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.
[0019] like Figures 1 to 2 As shown in the figure, an embodiment of the present invention provides a lead-acid battery plate curing chamber, including a curing chamber 1, with a curing cavity 10 formed inside the curing chamber 1. The curing cavity 10 is used to place the lead-acid battery plate to be cured. A first cavity 11 and a second cavity 12 are respectively provided above and below the curing cavity 10. The first cavity 11 is separated from the curing cavity 10 by a first porous plate 110, and the second cavity 12 is separated from the curing cavity 10 by a second porous plate 120. A sealing door 13 is provided on the front of the curing chamber body 1 for placing and removing the plate.
[0020] like Figure 2-4 The first cavity 11 and the second cavity 12 are respectively provided with a first air inlet / outlet structure 5 and a second air inlet / outlet structure 4. The first air inlet / outlet structure 5 and the second air inlet / outlet structure 4 have the same structure, each including a main pipe 50. Several parallel secondary pipes 51 are connected to one side of the main pipe 50, and the outer sides of the secondary pipes 51 are along their length. The first cavity 11 and the second cavity 12 are respectively connected to the outside through the first air inlet / outlet structure 5 and the second air inlet / outlet structure 4. Several through holes are opened in the first cavity 11. Vertical pipes 52 are connected to the through holes, and the ends of the vertical pipes 52 are connected to the bell mouth structure 53. Multiple air inlets / outlets are connected by the main pipe 50. The structure of the secondary pipe 52 with through holes enables large-area, uniform air intake or exhaust, avoiding excessively strong or weak local airflow and making the environment inside the curing chamber more uniform. The wide end of the flared structure 53 of the first air intake / exhaust structure 5 faces the first perforated plate 110; the wide end of the flared structure 53 of the second air intake / exhaust structure 4 faces the second perforated plate 120, optimizing the airflow pattern and allowing the airflow to pass smoothly through the second perforated plate 120 and the first perforated plate 110 in a diffused or converged manner, reducing the direct impact of the airflow on the second perforated plate 120 and the first perforated plate 110, and making the airflow distribution better.
[0021] To facilitate control of gas flow within the curing chamber 1, a drive system is also provided. The first inlet / outlet structure 5 and the second inlet / outlet structure 4 are respectively connected to the drive system. During use, the first inlet / outlet structure 5 and the second inlet / outlet structure 4 alternately serve as the inlet and outlet ends. The drive system includes a circulating fan, which is connected to the first inlet / outlet structure 5 through a first pipe and to the second inlet / outlet structure 4 through a second pipe. A processing box is provided on the first or second pipe, and the processing box contains an atomizing humidification unit, an oxygen replenishment unit, and a heating unit.
[0022] When the curing chamber 1 is working, the circulating fan starts, driving the airflow to circulate within the curing chamber 1; taking the first air inlet / outlet structure 5 as the air inlet and the second air inlet / outlet structure 4 as the air outlet as an example: Airflow enters from the main pipe 50 of the first air inlet / outlet structure 5, and is distributed to each vertical pipe 52 through the through hole on the secondary pipe 51. Through the diffusion effect of the flared structure 53, the airflow enters the first cavity 11 evenly, and then passes evenly downward through the electrode stack in the curing chamber 10 via the first porous plate 110. Subsequently, the airflow enters the second cavity 12 through the second porous plate 120, and then converges to the main pipe 50 through the flared structure 53, the vertical pipe 52, and the secondary pipe 51 of the second air inlet / outlet structure 4, and finally exits from the curing chamber.
[0023] The processing chamber is equipped with a humidification unit, an oxygen supply unit, and a heating unit. After the airflow exits from the outlet, it enters the processing chamber for treatment: the humidification unit regulates humidity, the oxygen supply unit replenishes oxygen, and the heating unit regulates temperature. The treated airflow then re-enters the curing chamber through the inlet, forming a closed-loop cycle. The control system monitors environmental parameters in real time using temperature and humidity sensors and oxygen concentration sensors installed within the curing chamber 10. Based on a preset curing process curve, it automatically adjusts the operating status of the humidification unit, oxygen supply unit, and heating unit to maintain the temperature, humidity, and oxygen concentration within the curing chamber 10 within the set range, providing optimal process conditions for electrode curing.
[0024] like Figure 3-4 To prevent blockage of the flared structure 53, vertical tube 52, and other parts by lead paste dust during use, openings are provided at the ends of the first cavity 11 and the second cavity 12. A first drawer structure 3 and a second drawer structure 2 are respectively installed inside the first cavity 11 and the second cavity 12. The first drawer structure 3 and the second drawer structure 2 are equipped with a covering structure that can controllably cover the wide end of the flared structure 53. The first drawer structure 3 and the second drawer structure 2 have identical structures, both including a rectangular frame 21 passing through the opening. A fixed end plate 20 is provided on one side of the rectangular frame 21, and a handle 201 is provided on the outside of the fixed end plate 20. The inner wall of the end plate 20 is provided with a sealing layer, ensuring good sealing. First support beams 111 are respectively provided on the opposite side walls of the first cavity 11, and second support beams 121 are respectively provided on the opposite side walls of the second cavity 12. A rectangular frame 21 is supported on the upper surface of the first support beams 111 and 121. First limiting beams 112 and 122 are respectively provided on the inner and outer sides of the first cavity 11 and the second cavity 12 to detect the insertion position of the first drawer structure 3 and the second drawer structure 2. When the first drawer structure 3 and the second drawer structure 2 are respectively inserted into the first cavity 11 and the second cavity 12, the end face of the rectangular frame 21 abuts against the first limiting beam 112 or the second limiting beam 122. A first pressure sensor and a second pressure sensor are respectively provided on the first limiting beam 112 or the second limiting beam 122. The setting of the first limiting beam 112 and the second limiting beam 122 facilitates the detection of whether the first drawer structure 3 and the second drawer structure 2 are inserted and installed correctly.
[0025] The number and position of the covering structure and the flared structure 53 are matched one-to-one; adjacent covering structures are connected by the first connecting rod 22, and the two covering structures at both ends are connected to the inner wall of the rectangular frame 21 by the second connecting rod.
[0026] like Figure 3-5 The covering structure includes a first ring body 23. Multiple elastic telescopic members 231 are connected to one side of the first ring body 23 near the flared structure 53. A filter assembly is connected to the end of each elastic telescopic member 231. A stepped portion 531 for inserting the filter assembly is provided at the open end of the flared structure 53. The filter assembly includes a second ring body 232 connected to the end of the elastic telescopic member 231. A magnetic ring 234 is detachably connected to the side of the second ring body 232 away from the first ring body 23 by bolts. A filter 233 is clamped and fixed between the magnetic ring 234 and the second ring body 232. Rubber layers are provided on opposite sides of the magnetic ring 234 and the stepped portion 531. A ring-shaped electromagnet 54 is embedded within the stepped portion 531. The filter 233 can filter impurities such as lead paste dust in the airflow.
[0027] After the first drawer structure 3 and the second drawer structure 2 are installed in place, the control electromagnet 54 is de-energized. At this time, under the action of gravity and magnetic force, the filter assembly is inserted into the step portion 531. The airflow must pass through the filter 233 before entering the space composed of the flared structure 53, the vertical pipe 52, etc. During the installation and disassembly of the first drawer structure 3 and the second drawer structure 2, the control electromagnet 54 is energized. At this time, under the action of the elastic telescopic member 231, a gap is formed between the flared structure 53 and the filter assembly, which facilitates the installation and disassembly of the first drawer structure 3 and the second drawer structure 2.
[0028] A base plate 230 is installed on the first ring 23 of the first drawer structure 3. The base plate 230 is located on the side of the first ring 23 away from the flared structure 53. When the first air inlet / outlet structure 5 is switched to the air outlet, the reverse airflow blows off the lead paste dust and other impurities attached to the filter screen 233. The blown-off lead paste dust and other impurities fall onto the base plate 230. At this time, after the first drawer structure 3 is removed, the lead paste dust and other impurities accumulated on the base plate 230 are cleaned.
[0029] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
