Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery manufacturing. Background Technology

[0002] In the curing and drying process of wet electrode plates, the main reactions of the active material in the electrode plate during the curing process include the oxidation of metallic lead in the active material, in which the moisture inside the electrode plate acts as a catalyst for the oxidation process; interfacial (the contact surface between the grid and the active material) corrosion oxidation and gelation. During this process, it is necessary to maintain the moisture content inside the electrode plate to promote corrosion oxidation and gelation. It is evident that the electrode plate needs to be kept moist during the curing stage. Currently, the moisturizing method in the process is to spray atomized water inside the curing chamber, and at the same time, to maintain the humidity inside the curing chamber by forming an airflow to diffuse the atomized water. During the drying process, the air inside the curing chamber is heated and forced convection is formed to heat the electrode plate inside the curing chamber to remove the moisture inside the electrode plate. A complete production cycle of the curing chamber in the curing process is to humidify and heat the curing chamber during the curing stage. After the curing reaction is completed, it is transferred to the drying stage. In the drying stage, the air is directly heated electrically and then the heat is transferred to the electrode plate through the air to heat the moisture inside the electrode plate to complete the drying process. This has the problems of water consumption, electricity consumption, long drying time and low curing efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned deficiencies of related technologies and provide a regenerative adsorption curing chamber.

[0004] The technical solution adopted by this utility model is as follows: a regenerative adsorption curing chamber, including a curing chamber body, an atomizer disposed inside the curing chamber body for spraying atomized water during the plate curing stage, a circulating fan disposed outside the curing chamber body for sending air into the curing chamber body during the plate curing stage, an electric heater for heating air, a molecular sieve adsorber for adsorbing moisture in the air during the plate drying stage and desorbing the adsorbed moisture during the plate curing stage for humidification, and an air compressor for pressurizing air and sending it into the molecular sieve adsorber for dehydration during the plate drying stage.

[0005] The curing chamber has a top air outlet and a bottom air inlet; the circulating fan inlet is connected to the top air outlet of the curing chamber; the circulating fan outlet is connected to the electric heater inlet; it also includes an air inlet pipe, one end of which is connected to the circulating fan inlet and the other end is connected to the atmosphere; a shut-off valve is provided on the air inlet pipe.

[0006] The upper air inlet of the air compressor is connected to the air outlet of the electric heater via pipe two; the lower air outlet of the air compressor is connected to the lower air inlet of the molecular sieve adsorber via pipe three; and the upper air outlet of the molecular sieve adsorber is connected to the lower air inlet of the curing chamber via pipe four.

[0007] The circulating fan is located at the top of the curing chamber body; the electric heater is located at the top of the curing chamber body.

[0008] The front of the curing chamber body has an opening that facilitates the feeding of the electrode plate to be cured into the curing chamber and its removal from the curing chamber after curing is completed.

[0009] The air compressor is located on the back of the curing chamber body; the molecular sieve adsorber is located on the back of the curing chamber body.

[0010] The lower air inlet is located on the back or side of the curing chamber body.

[0011] Compared with existing technologies, the advantages of this invention are as follows: During the plate drying stage, the air compressor draws air from upstream under a certain pressure, which then comes into contact with the molecular sieve desiccant inside the molecular sieve adsorbent. Most of the moisture is adsorbed into the molecular sieve desiccant. The dried air then enters the curing chamber to achieve deep drying. During the curing stage, the compressor stops working, the molecular sieve desiccant returns to normal pressure, and the moisture adsorbed in the previous drying stage is desorbed and sent into the curing chamber by a circulating fan for humidification, saving the purified water originally used for humidification. The plate drying method in the drying stage is changed from forced heating to a combination of reducing the saturated vapor pressure on the plate surface and heating, greatly accelerating the plate drying speed and saving energy consumption. The moisture that should have been separated during the drying stage remains inside the molecular sieve for use in the next curing stage, reducing the amount of atomized water used in the curing stage. During the curing stage, the moisture adsorbed inside the molecular sieve desorbs and enters the curing chamber, saving water used in the curing stage. The compressed air in the drying stage increases the internal pressure of the molecular sieve, enhancing its adsorption capacity, reducing air humidity, improving the drying effect, and saving heating electricity costs.

[0016] like Figure 1 As shown, the regenerative adsorption curing chamber provided by this utility model includes a curing chamber body 1. The top of the curing chamber body 1 is provided with a top air outlet 11, and the lower back of the curing chamber body 1 is provided with a bottom air inlet 10. Inside the curing chamber body 1 is an atomizer 8 for spraying atomized water during the electrode curing stage. The top of the curing chamber body 1 is provided with a circulating fan 3 for supplying air into the curing chamber body 1 during the electrode curing stage, and an electric heater 4 for heating the air. The air inlet of the circulating fan 3 is connected to the top air outlet 11 of the curing chamber; the air outlet of the circulating fan 3 is connected to the air inlet of the electric heater 4; it also includes an air inlet pipe 2, one end of which is connected to the air inlet of the circulating fan 3, and the other end is connected to the atmosphere; the air inlet pipe 2 is provided with a shut-off valve 6 that opens during the electrode curing stage and closes during the electrode drying stage.

[0017] The front of the curing chamber body 1 has an opening for easy feeding of the electrode plate to be cured into the curing chamber and removing it from the curing chamber after curing. The back of the curing chamber body 1 has an air compressor 5 for pressurizing and feeding air into the molecular sieve adsorber 12 during the electrode plate drying stage, and a molecular sieve adsorber 12 for adsorbing moisture from the air.

[0018] The upper air inlet 51 of the air compressor 5 is connected to the air outlet of the electric heater 4 via pipe 2 13; the lower air outlet 52 of the air compressor 5 is connected to the lower air inlet 121 of the molecular sieve adsorber 12 via pipe 3 14; the upper air outlet 122 of the molecular sieve adsorber 12 is connected to the lower air inlet 10 of the curing chamber via pipe 4 15.

[0019] In use, this invention begins by opening the door to the curing chamber and placing the curing rack containing the electrode plates inside. Once this is complete, the curing stage begins. During curing, a circulating fan is activated, creating airflow within the curing chamber. The outside air and the air inside the curing chamber are heated to approximately 45 degrees Celsius by an electric heater. The air then passes through an air compressor and a molecular sieve adsorber. At this stage, the air compressor is not running. Moisture desorbed from the molecular sieve adsorber enters the curing chamber through the lower air inlet, humidifying the air inside the chamber along with atomized water. During the drying stage, the shut-off valve is closed, and the atomized water humidification continues. The airflow circulation is the same as in the curing stage. The electric heater heats the air to 90 degrees Celsius, the air compressor is activated, increasing the pressure and thus the molecular sieve adsorber's adsorption capacity. Moisture in the air remains within the molecular sieve, reducing air humidity and improving the drying effect.
