Description

Technical Field

[0001] This invention relates to the field of battery production equipment, and more specifically, to a curing chamber oxygen supply device and its usage method. Background Technology

[0002] In the manufacturing process of lead-acid batteries, plate curing is one of the key processes. The quality of the plates determines the battery's performance indicators and service life. Currently, the prominent problems with plates include poor plate strength, unstable consistency of plate indicators, and long curing time, which affect production efficiency.

[0003] To improve battery lifespan, existing technologies typically employ high-temperature and high-humidity curing. The curing chamber is highly sealed, resulting in less oxygen entering the chamber during the curing stage and a significantly lower overall oxygen concentration, which is detrimental to the oxidation of free lead in the plates.

[0004] Chinese patent CN210272541U discloses an oxygen supplementation device for a curing chamber, providing a technical solution that supplements oxygen by setting up several sets of oxygen supplementation pipes in the curing chamber.

[0005] Although the aforementioned patent can provide oxygen supplementation, the oxygen supplementation tube remains fixed during the oxygen supplementation process, resulting in a relatively concentrated oxygen supply that does not diffuse sufficiently within the curing chamber. Consequently, the plates located far from the oxygen supplementation position receive less oxygen, preventing them from absorbing oxygen evenly and thus affecting the curing effect.

[0006] Therefore, an oxygen supplementation device for a curing chamber and its usage method are proposed. Summary of the Invention

[0007] The purpose of this invention is to provide an oxygen supplementation device for a curing chamber and its method of use, so as to solve the problems mentioned in the background art.

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] An oxygen supplementation device for a curing chamber includes a curing chamber. An air inlet pipe is fixedly connected to the upper end face of the curing chamber via a pipe frame. A second conduit and a first conduit are fixedly connected to the upper and lower sides of the right side of the curing chamber via pipe frames, respectively. Several first branch pipes are horizontally and equidistantly connected to each other on the corresponding sides of the first and second conduits. A first vertical pipe is rotatably connected to two corresponding first branch pipes in the vertical direction.

[0010] A first volute is fixedly connected to the right side of the curing chamber near the top. A first drive shaft is rotatably connected to the center of the first volute. A first impeller is fixedly sleeved on the first drive shaft. The air outlet of the air inlet pipe is connected to the upper part of the outer annular surface of the first volute. An air outlet pipe is connected to the lower part of the outer annular surface of the first volute. The air outlet of the air outlet pipe is connected to the front end of the first duct.

[0011] The left end of the first drive shaft extends into the curing chamber, and the left end of the first drive shaft is provided with a drive mechanism, which can drive the first vertical tube to rotate to expand the diffusion range of oxygen.

[0012] Furthermore, the driving mechanism includes a first plate frame with a T-shaped cross-section fixedly connected to the upper position of the right side of the curing chamber. A first toothed plate matching it is slidably sleeved on the first plate frame, and a second gear meshing with the first toothed plate is fixedly sleeved on the upper part of the annular outer surface of each first vertical tube.

[0013] Furthermore, a first fixed shaft is fixedly connected to the inner wall of the curing chamber above the first plate frame, and a first gear with a sector-shaped structure is rotatably sleeved on the first fixed shaft. The upper surface of the first gear plate has first teeth that mesh with the first gear.

[0014] Furthermore, a first support plate is fixedly connected to the upper end of the first gear, and a first slot is opened on the first support plate. The left end of the first transmission shaft is flush with the center position of the first slot and is fixedly connected to an L-shaped first crank. The crankshaft at the end of the first crank is inserted into the first slot, and the length of the first crank is less than half of the first slot.

[0015] Furthermore, a fourth conduit and a third conduit are fixedly connected to the upper and lower sides of the left side of the curing chamber via a pipe rack. The third conduit and the fourth conduit are connected to several second branch pipes at equal intervals on their corresponding sides, and a second vertical pipe is rotatably connected to two corresponding second branch pipes in the vertical direction.

[0016] Furthermore, a second plate frame with an L-shaped cross-section is fixedly connected to the lower left side of the curing chamber. A matching second toothed plate is slidably sleeved on the second plate frame. A fourth gear that meshes with the second toothed plate is fixedly sleeved on the lower part of the annular outer side of each second vertical tube.

[0017] Furthermore, a second fixed shaft is fixedly connected to the inner wall of the curing chamber above the second toothed plate, and a third gear with a fan-shaped structure is rotatably sleeved on the second fixed shaft. The upper surface of the second toothed plate is evenly distributed with second teeth that mesh with the third gear. A second support plate is fixedly connected to the upper end of the third gear, and a second slot is opened on the second support plate.

[0018] Furthermore, a second volute is fixedly connected to the left side of the curing chamber near the bottom. A second drive shaft is rotatably connected to the center of the second volute. A second impeller is fixedly sleeved on the second drive shaft. The right end of the second drive shaft passes through the interior of the curing chamber and is fixedly connected to a second crank. The center of the second drive shaft is flush with the center of the second slot. The crankshaft at the end of the second crank is inserted into the second slot, and the length of the second crank is less than half of the second slot.

[0019] Furthermore, an air inlet pipe is connected to the upper end of the annular outer surface of the second volute, and the portion of the air inlet pipe near the air inlet is wrapped around the air inlet pipe. An air outlet pipe is connected to the lower end of the annular outer surface of the second volute, and the air outlet of the air outlet pipe is connected to the front end of the third conduit.

[0020] A method for using an oxygen supply device for a curing chamber includes the following steps:

[0021] S1: Install the first and second vertical tubes symmetrically on the left and right sides inside the curing chamber, and then stack the electrode plates between the first and second vertical tubes.

[0022] S2: Connect the air inlet of the air inlet pipe to the oxygen generator. The oxygen generated by the oxygen generator is used to deliver oxygen to the curing chamber. When the oxygen passes through the first impeller, it will drive the first impeller to rotate, thereby driving the first vertical pipe to rotate back and forth.

[0023] S3: Connect the air inlet of the air inlet pipe to the steam generator. The steam generated by the steam generator is used to deliver steam into the curing chamber. When the steam passes through the second impeller, it will drive the second impeller to rotate, thereby driving the second vertical pipe to rotate back and forth.

[0024] Furthermore,

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. This solution not only facilitates the stacking of electrode plates by placing the first vertical tube on the right side of the curing chamber, but also, by setting a driving mechanism, allows the first vertical tube to rotate back and forth when oxygen passes through the first volute, thereby expanding the diffusion range of oxygen, ensuring that the electrode plates can absorb oxygen evenly, and thus improving the curing quality of the electrode plates.

[0027] 2. This solution involves installing a second vertical pipe on the left side of the curing chamber and using a steam generator to replenish water vapor inside the curing chamber, thereby ensuring the temperature and humidity inside the curing chamber and maintaining a dynamic balance in the moisture content of the lead paste.

[0028] 3. This solution heats the oxygen inside the air intake pipe by wrapping the air intake pipe around it, thus preventing low-temperature oxygen from entering the curing chamber and causing temperature changes inside the curing chamber. Attached Figure Description

Detailed Implementation

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1 to 8 A curing chamber oxygen supply device and its usage method are disclosed. The device includes a curing chamber 1. An air inlet pipe 24 is fixedly connected to the upper end face of the curing chamber 1 via a pipe frame. A second conduit 44 and a first conduit 4 are fixedly connected to the upper and lower sides of the right side of the curing chamber 1 via pipe frames, respectively. Several first branch pipes 41 are horizontally and equidistantly connected to each other on the corresponding sides of the first conduit 4 and the second conduit 44. A first vertical pipe 42 is rotatably connected to two corresponding first branch pipes 41 in the vertical direction.

[0041] A first volute 2 is fixedly connected to the upper right side of the curing chamber 1. A first drive shaft 22 is rotatably connected to the center of the first volute 2. A first impeller 21 is fixedly sleeved on the first drive shaft 22. The air outlet of the air inlet pipe 24 is connected to the upper part of the annular outer surface of the first volute 2. An air outlet pipe 25 is connected to the lower part of the annular outer surface of the first volute 2. The air outlet of the air outlet pipe 25 is connected to the front end of the first duct 4. The left end of the first drive shaft 22 extends into the interior of the curing chamber 1, and a drive mechanism is provided at the left end of the first drive shaft 22.

[0042] By adopting the above technical solution, the driving mechanism includes a first plate frame 31 with a T-shaped cross-section, fixedly connected to the upper part of the right side of the curing chamber 1. A first toothed plate 3 is slidably sleeved on the first plate frame 31. A second gear 43 that meshes with the first toothed plate 3 is fixedly sleeved on the upper part of the annular outer surface of each first vertical tube 42. A first fixed shaft 34 is fixedly connected to the inner wall of the curing chamber 1 above the first plate frame 31. A fan-shaped first gear 33 is rotatably sleeved on the first fixed shaft 34. First teeth 32 that mesh with the first gear 33 are evenly distributed on the upper end surface of the first toothed plate 3. A first support plate 35 is fixedly connected to the upper end of the first gear 33. A first slot 36 is provided on a plate 35, connecting the air inlet of the air inlet pipe 24 to the oxygen generator. The plates are then stacked in the curing chamber. The first vertical pipe 42 is conveniently located on the right side inside the curing chamber 1 for workers to place the plates. The curing chamber door is then closed, and the oxygen generator is started to produce oxygen. The generated oxygen, pressurized by the booster pump, enters the first volute 2 through the air inlet pipe 24. Each first vertical pipe 42 is connected to a nozzle. Oxygen enters the first duct 4 through the air outlet pipe 25, then is branched through the first branch pipe 41 to the first vertical pipe 42, and finally ejected through the nozzles on the first vertical pipe 42. As the oxygen passes through the first volute 2, it drives the first... The impeller 21 rotates, which in turn drives the first drive shaft 22 to rotate. Since the left end of the first drive shaft 22 is flush with the center of the first slot 36 and fixedly connected to an L-shaped first crank 23, the crankshaft of the first crank 23 is inserted into the first slot 36, and the length of the first crank 23 is less than half the length of the first slot 36. This causes the first crank 23 to rotate, and the crankshaft of the first crank 23 rotates within the first slot 36. This, in turn, causes the first support plate 35 to oscillate back and forth around the first fixed shaft 34, causing the first gear 33 to synchronously rotate back and forth around the first fixed shaft 34. The central angle of the first gear 33 is 120°. The first vertical tube 42 can rotate 60° forward or backward around the first fixed axis 34, thereby driving the first toothed plate 3 to move backward or forward. This causes the first vertical tube 42 to rotate 60° forward or backward on the first branch tube 41 at its respective position, allowing oxygen to diffuse to the periphery of the curing chamber, increasing the oxygen diffusion range, ensuring that each electrode plate can absorb oxygen evenly, and thus improving the curing quality of the electrode plate. The rear end of the first conduit 4 is in a blocked state, and both the front and rear ends of the second conduit 44 are in a blocked state, so that the oxygen entering the first conduit 4 and the second conduit 44 can only be sprayed out through the nozzle on the first vertical tube 42, ensuring that the oxygen can diffuse evenly to the surroundings.

[0043] like Figures 2 to 8As shown, inside the curing chamber 1, a fourth conduit 74 and a third conduit 7 are fixedly connected to the upper and lower sides of the left side via pipe racks. Several second branch pipes 71 are horizontally and equidistantly connected to each other on opposite sides of the third conduit 7 and the fourth conduit 74. A second vertical pipe 72 is rotatably connected to two corresponding second branch pipes 71 in the vertical direction. A second plate frame 61 with an L-shaped cross-section is fixedly connected to the lower left side of the curing chamber 1. A matching second toothed plate 6 is slidably fitted on the second plate frame 61. A fourth gear 73 that meshes with the second toothed plate 6 is fixedly fitted to the lower part of the annular outer side of each second vertical pipe 72. A second fixed shaft 64 is fixedly connected to the inner wall of the curing chamber 1 above the second toothed plate 6. A third gear 63 with a fan-shaped structure is rotatably mounted on the upper part of the second gear plate 6. The upper end face of the second gear plate 6 has evenly distributed second teeth 62 that mesh with the third gear 63. A second support plate 65 is fixedly connected to the upper end of the third gear 63. A second slot 66 is opened on the second support plate 65. A second volute 5 is fixedly connected to the lower left side of the curing chamber 1. A second drive shaft 52 is rotatably connected to the center of the second volute 5. A second impeller 51 is fixedly mounted on the second drive shaft 52. An air inlet pipe 54 is connected to the upper end of the annular outer side of the second volute 5. The part of the air inlet pipe 24 near the air inlet is wrapped around the air inlet pipe 54. An air outlet pipe 55 is connected to the lower end of the annular outer side of the second volute 5. The air outlet of the air outlet pipe 55 is connected to the front end of the third conduit 7.

[0044] By adopting the above technical solution, the second vertical pipes 72 are symmetrically arranged on the left side inside the curing chamber 1, so that the space between the first vertical pipe 42 and the second vertical pipe 72 is used for stacking electrode plates, and at the same time, it is convenient for personnel to enter and exit the curing chamber 1. The air inlet of the air inlet pipe 54 is connected to the steam generator, and the steam generator generates water vapor, which is then transported into the curing chamber 1 through a booster pump. Several atomizing nozzles are evenly connected to each second vertical pipe 72. The water vapor enters the third conduit 7 through the air outlet pipe 55, then enters each second vertical pipe 72 through the second branch pipe 71, and finally is sprayed out through the atomizing nozzles on the second vertical pipe 72. The water vapor passes through the first... When the second volute 5 is inside the second volute 5, it will drive the second impeller 51 to rotate, thereby driving the second drive shaft 52 to rotate. Since the right end of the second drive shaft 52 passes through the interior of the curing chamber 1 and is fixedly connected to the second crank 53, and the center position of the second drive shaft 52 is flush with the second slot 66, the crankshaft at the end of the second crank 53 is inserted into the second slot 66, and the length of the second crank 53 is less than half of the second slot 66, thereby driving the second support plate 65 to swing back and forth around the second fixed shaft 64, causing the third gear 63 to rotate backward or forward around the second fixed shaft 64, thereby driving the second gear plate 6 to slide back and forth backward or forward. The central angle of the three gears 63 is 120°, and the third gear 63 can rotate 60° forward or backward around the second fixed shaft 64. This, in turn, drives the fourth gear 73 to rotate 60° backward or forward via the second gear plate 6, causing the second vertical tube 72 to rotate 60° backward or forward synchronously. This ensures that water vapor can be evenly dispersed throughout the curing chamber 1, maintaining a balanced temperature and humidity inside the curing chamber 1. When the RH is close to 100%, the rate of moisture diffusion outward from the lead paste increases. Simultaneously, the rate of penetration of hot water vapor into the lead paste also increases. Both rates accelerate with increasing temperature, thus... The moisture content of the lead paste will quickly maintain a certain dynamic equilibrium. A part of the air inlet pipe 24 is wrapped around the air inlet pipe 54. The heat emitted by the water vapor is conducted to the air inlet pipe 24 through the air inlet pipe 54 to heat the oxygen. This ensures that the oxygen does not disrupt the temperature balance after entering the curing chamber 1, thus guaranteeing the curing quality of the electrode plate. The rear end of the third conduit 7 is blocked, and both ends of the fourth conduit 74 are also blocked. This ensures that the water vapor entering the third conduit 7 and the fourth conduit 74 can only be sprayed out through the atomizing nozzle on the second vertical pipe 72, ensuring the uniform diffusion of water vapor and thus ensuring the balance of temperature and humidity inside the curing chamber 1.

[0045] A method for using an oxygen supply device in a curing chamber 1, characterized by comprising the following steps:

[0046] S1: The first vertical tube 42 and the second vertical tube 72 are symmetrically installed on the left and right sides inside the curing chamber 1, and then the electrode plates are stacked between the first vertical tube 42 and the second vertical tube 72.

[0047] S2: Connect the air inlet of the air inlet pipe 24 to the oxygen generator. The oxygen generated by the oxygen generator is used to deliver oxygen into the curing chamber 1. When the oxygen passes through the first impeller 21, it will drive the first impeller 21 to rotate, thereby driving the first vertical pipe 42 to rotate back and forth.

[0048] S3: Connect the air inlet of the air inlet pipe 54 to the steam generator. The steam generated by the steam generator is used to deliver water vapor into the curing chamber 1. When the water vapor passes through the second impeller 51, it will drive the second impeller 51 to rotate, thereby driving the second vertical pipe 72 to rotate back and forth.

[0049] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
