Description

Technical Field

[0001] The present application relates to the technical field of battery curing chambers, and in particular to a battery plate curing chamber. Background Art

[0002] In the process of manufacturing the plates of lead-acid batteries, curing and drying the green plates is a key and important process. The lead paste particles coated on the green plates and the connection between the lead paste particles and the grids are loose and not firm. Therefore, it is necessary to maintain a certain temperature, humidity and oxygen conditions in the curing room to oxidize the grids to form a corrosion layer that is firmly combined with the active substances in the lead paste, so that a continuous and firm skeleton structure is formed between the active substances in the lead paste, and at the same time, the free lead in the lead paste is oxidized and the hardness and mechanical strength of the lead paste are enhanced. Therefore, the curing room that provides the conditions required for curing and drying the green plates determines the process of physical and chemical reactions in the lead paste, affects the active substance components of the lead paste, determines the capacity and life of the battery, and has a significant and critical impact on the battery performance.

[0003] The existing curing rooms are Figure 1 As shown, during the curing and drying process, the airflow is blown in from one side and flows out from the other side, and the hot and humid steam runs upward, so the humidity and temperature in the curing room cannot be guaranteed to be uniform. The bottom of the curing room has high humidity and low temperature, while the upper part has low humidity and high temperature. The temperature, moisture, and free lead content of the plates at different positions in the curing room are inconsistent, the quality of the plates is inconsistent, and the performance consistency of the assembled batteries is poor. In addition, due to structural constraints, it is difficult for the existing plate curing room to ensure a high humidity in the curing space while ensuring a certain temperature, resulting in a long curing and drying time, about 3 days, and high energy consumption.

[0004] In the Chinese patent literature, patent number CN 2021104567092 disclosed a battery plate curing chamber on July 30, 2021. The application includes a curing chamber body and a plate frame. A group of evaporators are arranged below the left and right sides of the outside of the curing chamber body; a number of groups of blowing pipes are erected on the left and right sides of the inner wall of the curing chamber body, and the top of the evaporator is connected to the blowing pipe through a steam pipeline. The blowing pipe is provided with a number of nozzles from top to bottom; a number of groups of microwave tubes are arranged on the inner wall of the rear side of the curing chamber body; the plate frame includes a supporting frame and a number of layers of partitions, each group of partitions and the supporting frame form a compartment, and the partition is provided with multiple groups of through holes, and a liquid baffle is arranged horizontally above the compartment; the center of the top of the curing chamber body is sealed and connected to the exhaust system; a number of groups of baffles are erected on each group of partitions, and the baffles include a base and a plate body, and a number of plug cavities are arranged at intervals on the plate body, and UV lamps are installed in each group of plug cavities. The application is to form sufficient convection air through multiple nozzles to improve the curing efficiency. The disadvantage is that the several nozzles arranged on the side of the curing chamber are mainly used to complete the convection of the outer wall of the curing chamber. The plate frame in the plate curing chamber is folded, and the air convection in the curing area is slightly improved, so the curing efficiency of the plate is unreliable. Summary of the invention

[0005] Based on the problem that humidity, temperature and free lead content at different positions in the battery plate curing chamber in the prior art are inconsistent, resulting in long curing time and poor curing quality, the present invention provides a battery plate curing chamber that can more evenly disperse the curing medium to different curing racks, thereby improving curing efficiency and enhancing curing quality.

[0006] The second object of the present invention is to make full use of the heat in the curing chamber to preheat the curing airflow and reduce energy consumption.

[0007] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions.

The airflow is heated in the airflow chamber to complete the mixing of the airflow and steam, and the temperature and humidity in the curing chamber are ensured to be reliable through the temperature and humidity detection component to ensure the curing efficiency.

[0011] Preferably, the airflow chamber includes an air intake area corresponding to the upper side of the curing chamber and a diversion area corresponding to the side of the curing chamber, the axial flow fan and the heating assembly are arranged in the air intake area, and an airflow chamber valve is arranged between the air intake area and the diversion area. The air intake area completes the air intake and airflow heating, and the heated airflow is mixed with steam in the diversion area to ensure the temperature and humidity of the airflow entering the curing rack; the airflow chamber valve can adjust the mixing ratio of the airflow and steam, which is convenient for adjusting the airflow humidity in the curing chamber.

[0012] Preferably, the airflow base is arranged on the side of the diversion area, and adjacent airflow bases are arranged at equal intervals. The diversion area is vertically arranged on one side of the curing chamber, and the airflow bases are arranged at equal intervals on the side of the diversion area, so that the diversion amount of several airflow bases is relatively uniform.

[0013] Preferably, the steam inlet pipe includes a steam outlet vertically arranged upward in the diversion area, and the position of the steam inlet pipe corresponds to the position of the lowest airflow base on the side of the diversion area. Steam flows out from the steam outlet from bottom to top, because steam has a higher density than air and is easy to sink, while the airflow entering the diversion area from the air inlet area flows from top to bottom, and the two form convection to achieve efficient heat and humidity exchange, thereby achieving high mixing efficiency, ensuring that the airflow entering different airflow bases has similar humidity, thereby improving curing efficiency.

The setting of the curing chamber valve can make the hot and humid airflow in the curing chamber flow back to the air inlet area, and this process is reliable, can preheat the airflow entering the air inlet, and increase the humidity of the airflow entering the air inlet, improve the utilization efficiency of heat and water vapor, and reduce energy consumption.

[0015] Preferably, the exhaust port and the valve in the curing chamber are respectively arranged on both sides of the upper end of the curing chamber, and an exhaust pipe passing through the air inlet area is arranged at the upper end of the curing chamber, and the exhaust port is located in the exhaust pipe; the upper end surface of the curing chamber is an inclined plane from the valve in the curing chamber to the air outlet pipe, and the air inlet of the axial flow fan is opposite to the inclined plane. The setting of the inclined plane forms a mixing zone separated from the axial flow fan and the air inlet, which facilitates the mixing of the humid and hot airflow returning from the curing chamber and the dry airflow entering from the air inlet, and facilitates the recovery of heat; because the exhaust pipe passes through the air inlet area, even if the valve in the curing chamber is closed, the curing chamber can recover heat to the airflow chamber, thereby improving the utilization efficiency of heat and reducing production energy consumption.

[0016] Preferably, the exhaust pipe corresponds to between the axial flow fan and the heating assembly. The high-humidity hot airflow in the curing chamber in the exhaust pipe can exchange heat with the heated intake airflow, ensuring the reliability of heat recovery from the curing chamber to the airflow chamber.

[0018] The present invention has the following beneficial effects: it can disperse the curing medium onto different curing racks relatively evenly, thereby improving the curing efficiency and the curing quality; it can make full use of the heat in the curing chamber to preheat the curing airflow and reduce energy consumption.

Figure 2 The schematic diagram is only a schematic diagram of the arrangement of the components of the present invention and does not represent the actual shape of the components. The outer surface of the whole formed by the airflow chamber and the curing chamber 15 is covered with a curing chamber insulation wall 3, and the curing chamber insulation wall 3 located on the side of the curing chamber 15 facing away from the airflow chamber adopts an insulation rolling shutter door 11.

[0025] An axial flow fan 7, a heating assembly 5 and a steam inlet pipe 2 are sequentially arranged in the airflow chamber along the airflow direction. A drain pipe is arranged at the bottom of the airflow chamber, and the drain pipe is arranged horizontally. A drain valve 1 is arranged in the drain pipe. The airflow chamber includes an air intake area 13 corresponding to the upper side of the curing chamber 15 and a diversion area 14 corresponding to the side of the curing chamber 15. The axial flow fan 7 and the heating assembly 5 are arranged in the air intake area 13, and an airflow chamber valve 4 is arranged between the air intake area 13 and the diversion area 14. The airflow chamber valve 4 is used to control whether the air intake area 13 and the diversion area 14 are connected.

[0026] Four curing racks are arranged in the curing chamber 15, which are not shown in the figure. The airflow chamber is provided with an air inlet 8 connected to the outside, and the air inlet 8 is arranged in the air inlet pipe, and an air inlet valve is arranged in the air inlet 8. The curing chamber 15 is provided with an exhaust port 6 connected to the outside, and an exhaust valve is arranged in the exhaust port 6. A curing chamber valve 9 that can connect the curing chamber 15 and the air inlet area 13 is arranged on the wall surface of the curing chamber 15 corresponding to the air inlet 8. The exhaust port 6 and the curing chamber valve 9 are arranged on both sides of the upper end of the curing chamber 15, respectively. An exhaust pipe passing through the air inlet area 13 is arranged at the upper end of the curing chamber 15, and the exhaust pipe corresponds to between the axial flow fan 7 and the heating assembly 5. The exhaust port 6 is located in the exhaust pipe; the upper end surface of the curing chamber 15 is an inclined plane 16 from the curing chamber valve 9 to the exhaust pipe, and the air inlet of the axial flow fan 7 is opposite to the inclined plane 16.

[0027] The airflow chamber is provided with four airflow bases 12 corresponding to the curing rack, and the airflow base 12 is provided with an air outlet connecting the curing chamber 15 and the airflow chamber. The airflow base 12 is arranged on the side of the diversion area 14, and adjacent airflow bases 12 are arranged at equal intervals. The diversion area 14 is arranged longitudinally on the side of the curing chamber 15, so the airflow base 12 is also arranged longitudinally along the side of the diversion area 14. The position of the steam inlet pipe 2 corresponds to the position of the airflow base 12 at the bottom of the side of the diversion area 14. The steam inlet pipe 2 includes a steam outlet arranged vertically upward in the diversion area 14. The curing rack is arranged on the upper side of the airflow base 12. A temperature and humidity detection component 10 is provided in the curing chamber 15, and the temperature and humidity detection component adopts a temperature and humidity detection sensor. The temperature and humidity detection sensor is arranged in the middle position above the airflow base 12 corresponding to the uppermost layer of the curing chamber 15.

[0028] The plate curing chamber in the prior art is as follows Figure 1As shown, the curing chamber 15 has a large overall reflux, and the humidity is regulated by spraying and humidifying after the air is inhaled. The gas after the curing reaction flows out of the curing chamber 15 to the outside and then mixes with the intake air after passing through the fan and heater. The temperature and humidity control is relatively loose, and the airflow corresponding to each curing rack has different flow rates, and the dry and wet mixing of the curing airflow is not sufficient. However, the present application achieves the diversion of the air in different curing racks through the airflow base 12 corresponding to different curing racks one by one, and the air outlet on the airflow base 12 is used to realize the diversion of the air in different curing racks, which can more evenly disperse the curing medium to different curing racks, improve the curing efficiency, and improve the curing quality; the steam flows out from the steam outlet from the bottom to the top, and the airflow entering the air intake area 13 in the diversion area 14 flows from the top to the bottom, and the two form convection to achieve efficient heat exchange and humidity exchange, so that the mixing efficiency is high, because the steam is denser than the air and is easy to sink, which ensures that the air intake of the lower curing rack is sufficient, thereby ensuring that the airflow humidity entering different airflow bases 12 is similar, thereby improving the curing efficiency. In addition, the present application can utilize the high-temperature and high-humidity gas in the curing chamber 15 to achieve preheating and prehumidification of the intake air, which can reduce energy consumption and has high economic value.
