Description

Technical Field

[0001] The utility model belongs to the technical field of battery manufacturing, and particularly relates to an oxygen replenishing device and a multi-channel oxygen replenishing curing chamber having the same. Background Art

[0002] The plate curing of lead-acid batteries refers to the process of coating the grid with active materials to form wet plates, placing the plates in a closed space, and hardening and dehydrating them under specified temperature and humidity conditions. During this process, the active materials recrystallize to form a special crystal structure and porous structure, and the free lead remaining in the plates is converted into lead oxide, and the lead paste is combined with the grid corrosion. During the curing process, in order to promote the oxidation of free lead, oxygen or air needs to be added to the curing room to promote the conversion of free lead into lead oxide.

[0003] For example, the Chinese utility model patent with publication number CN208028152U discloses a curing chamber, in which the top of the curing chamber body protrudes outward to form an oxygen supply cavity, and an oxygen supply port is provided on the side of the oxygen supply cavity. The top of the curing chamber body is provided with a track perpendicular to the side of the oxygen supply cavity where the oxygen supply port is located, and an oxygen supply door is movably provided on the track. The oxygen supply door is driven to open and close by a cylinder to achieve oxygen supply.

[0004] However, most existing curing chambers use single-channel oxygen supplementation. Insufficient oxygen supply during plate curing will cause a slow plate oxidation rate, and the oxygen distribution in the curing chamber is uneven, resulting in poor plate curing effect, which in turn leads to unstable battery performance. Utility Model Content

[0005] The purpose of the utility model is to provide an oxygen supply device and a multi-channel oxygen supply curing chamber. The oxygen supply device can drive the flow of hot and humid air in the curing chamber, and at the same time inhale fresh air from the outside through the flow of hot and humid air to supply oxygen to the curing chamber, and by adjusting the valve angle, control the amount of oxygen supply, improve the efficiency of plate curing, improve the effect of plate curing, and solve the problem in the background technology that insufficient oxygen supply in the curing chamber will cause a slow oxidation rate of the plate, and the distribution of oxygen in the curing chamber is uneven, and the poor curing effect of the plate causes unstable battery performance.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is an oxygen supplementation device, comprising a blower, a connecting pipe and an oxygen supplementation pipe. The blower comprises an air inlet and an air outlet. One end of the connecting pipe is connected to the air inlet, and one end of the oxygen supplementation pipe is connected to the peripheral side of the connecting pipe. A valve is rotatably installed in the oxygen supplementation pipe, and a driving component for driving the valve to rotate is installed on the peripheral side of the oxygen supplementation pipe to adjust the opening size of the oxygen supplementation pipe.

[0008] As a preferred technical solution of the present utility model, one end of the connecting pipe is connected to a first suction duct, the other end of the connecting pipe is connected to a second suction duct, and the end of the second suction duct away from the connecting pipe is connected to the suction port.

[0009] As a preferred technical solution of the present utility model, the driving component adopts a motor.

[0010] As a preferred technical solution of the present invention, a guide plate is fixed on the inner wall of the connection between the connecting pipe and the oxygen supply pipe on one side close to the first suction duct to prevent the hot and humid airflow flowing along the connecting pipe from blowing into the oxygen supply pipe and forming turbulence at the connection between the oxygen supply pipe and the connecting pipe.

[0011] A multi-channel oxygen-supplementing curing chamber comprises a curing chamber body and at least two oxygen-supplementing devices, wherein the oxygen-supplementing devices are fixedly mounted on the upper surface of the curing chamber body; the air inlet and the air outlet are both connected to the curing cavity inside the curing chamber body.

[0012] As a preferred technical solution of the present utility model, the first suction duct, the connecting pipe and the second suction duct are covered with a thermal insulation layer on their circumferential sides.

[0013] As a preferred technical solution of the utility model, the opening direction of the connecting pipe is downward, which reduces dust and impurities from falling into the oxygen supply pipe.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model drives the flow of hot and humid air in the curing room by setting an oxygen supplement device. On the one hand, the oxygen is evenly distributed in the curing room, improving the consistency of the plate curing quality; on the other hand, fresh air from the outside is inhaled through the flow of hot and humid air to supplement oxygen into the curing room, and the oxygen supplement amount is controlled by adjusting the valve angle to improve the plate curing effect.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "side", "top", "middle", "end", "inside", and "surface" indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limitations on the present invention.

[0029] At present, most of the curing chambers used in plate production use single-channel oxygen supplementation, which easily leads to insufficient oxygen supply in the curing chamber. Insufficient oxygen supply during plate curing will cause slow plate oxidation rate, uneven distribution of oxygen in the curing chamber, poor plate curing effect, and unstable battery performance. Based on this, this example provides a multi-channel oxygen supplementation curing chamber.

[0030] Figure 1 is a schematic diagram of the structure of the multi-channel oxygen supplementation curing chamber provided in this embodiment. Figure 1 In the embodiment, the curing chamber includes a curing chamber body 200 and two oxygen supplementing devices 100 installed on the upper surface of the curing chamber body 200. Of course, other numbers of oxygen supplementing devices 100 may be provided according to actual requirements of the power of the oxygen supplementing devices and the volume of the curing chamber.

[0031] See also Figure 2 As shown, the oxygen supplementation device 100 provided in this embodiment includes a fan 1, a first air suction duct 2, a connecting pipe 3, and a second air suction duct 5. Among them, the fan 1 includes an air suction port 101 and an air outlet 102, and the air outlet 102 is fixed to the upper surface of the curing chamber body 200 through a flange structure and communicates with the inside of the curing chamber body 200. The air suction port 101 is fixed to one end of the second air suction duct 5 by welding, and the other end of the second air suction duct 5 is connected to one end of the connecting pipe 3 by a flange, and the other end of the connecting pipe 3 is connected to one end of the first air suction duct 2 by a flange, and the other end of the first air suction duct 2 is fixed to the upper surface of the curing chamber body 200 by a flange structure and communicates with the inside of the curing chamber body 200.

[0032] In addition, an oxygen supply pipe 4 is connected to the peripheral side of the connecting pipe 3 , and one end of the oxygen supply pipe 4 is fixed to the peripheral side wall of the connecting pipe 3 by welding.

[0033] In this embodiment of the present invention, please refer to Figure 3 and Figure 4 As shown, a valve 401 is rotatably installed in the oxygen supplementation tube 4, and a motor 6 for driving the valve 401 to rotate is installed on the circumference of the oxygen supplementation tube 4 to adjust the opening size of the oxygen supplementation tube 4.

[0034] During operation, the fan 1 is started, and the hot and humid gas in the curing chamber body 200 will flow in from the first suction pipe 2, through the connecting pipe 3 and the second suction pipe 5, and flow back to the curing chamber body 200 from the air outlet 102, thereby driving the gas to be evenly distributed in the curing chamber and improving the consistency of the plate curing quality. An oxygen sensor is also installed in the curing chamber. When it is detected that the oxygen content in the curing chamber is insufficient, the control system controls the motor 6 to operate, driving the valve 401 to rotate a certain angle. At this time, the oxygen supply pipe 4 is opened, and under the negative pressure of the air flow in the connecting pipe 3, the outside air is sucked in from the oxygen supply pipe 4, and then flows into the curing chamber from the air outlet 102 to achieve oxygen supplementation. Among them, the angle of rotation of the valve 401 determines the amount of air sucked in from the outside, that is, determines the amount of oxygen supplemented, to achieve precise curing and improve the plate curing effect.

[0035] Among them, the two oxygen supplementing devices 100 are preferably symmetrically arranged on the upper surface of the curing chamber body 200, the first suction ducts 2 of the two are arranged in the middle of the upper surface of the curing chamber body 200, and the air outlets 102 are arranged on both sides of the upper surface of the curing chamber body 200, so that the airflow can be fully circulated in the curing chamber.

[0036] In addition, one oxygen supplementation device 100 or both oxygen supplementation devices 100 may be turned on according to the demand for oxygen supplementation to achieve energy saving.

[0037] In a preferred embodiment of the present invention, please refer to Figure 5 As shown, a guide plate 301 is fixed on the inner wall of the connection between the connecting pipe 3 and the oxygen supply pipe 4 on one side close to the first suction pipe 2. The hot and humid air flow sucked out from the curing chamber will not flow to the oxygen supply pipe 4, thereby no turbulence will be formed in the oxygen supply pipe 4, thereby ensuring the suction effect of the oxygen supply pipe 4.

[0038] In a preferred embodiment of the utility model, the first suction duct 2, the connecting pipe 3 and the second suction duct 5 are covered with a thermal insulation layer to prevent the hot and humid air flow sucked out of the curing chamber from cooling down during the flow process, thereby affecting the curing effect.

[0039] In a preferred embodiment of the present invention, please refer to Figure 6 As shown, the opening direction of the connecting pipe 3 faces downward or sideways. This design can effectively prevent dust and impurities from falling into the oxygen supply pipe 4 and then being sucked into the curing chamber, thereby ensuring the curing quality of the plate.

[0040] In summary, this embodiment improves the curing rate of the electrode plate by adopting dual-channel variable frequency oxygen supply, and reduces the curing time from the original 50h to 40h, thereby reducing energy consumption, while improving the curing quality of the electrode plate, and has high practicality.
