Description

Technical Field

[0001] This invention relates to the field of storage battery manufacturing technology, and in particular to a high-precision infrared moisture analyzer for storage batteries. Background Technology

[0002] In the battery production process, the degree of dryness of the plates after coating directly affects the battery capacity and lifespan. Therefore, it is necessary to control the moisture content. Generally, the plates are sampled and tested using an infrared moisture analyzer. The infrared moisture analyzer uses infrared radiation to heat the sample to evaporate the moisture, while the built-in precision weighing sensor continuously records the changes in sample mass, thereby calculating the moisture content.

[0003] Existing infrared moisture analyzers typically heat the battery plates directly during use, which can easily lead to uneven heating, deformation, and cracking of the plates. This causes the fixed particles on the plates to be carried away with the moisture, damaging the plates and causing detection errors. Furthermore, direct heating is not fast enough to evaporate the moisture.

[0004] To address the above issues, we propose a high-precision infrared moisture analyzer for storage batteries. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by providing a high-precision infrared moisture analyzer for storage batteries.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision infrared moisture analyzer for storage batteries, comprising: A control panel and a measuring chamber are fixedly installed together. A fixed cover plate is rotatably installed on the control panel via a hinge, and a measuring plate is fixedly installed inside the measuring chamber. The purification structure includes a protective shell fixedly mounted on a measuring plate. A sealing plate is fixedly snapped onto the protective shell.

A heating box is fixedly mounted on the inner wall of the measuring chamber. A filter element is fixedly mounted on the heating box by fixing bolts. A fixed tube is fixedly mounted on the filter element. A connecting tube is slidably sleeved on the fixed tube and communicates with the interior of the fixed cylinder. A circulation tube is fixedly mounted on the heating box and communicates with the interior of the protective shell. A placement structure is mounted on the measuring plate.

[0007] In the aforementioned high-precision infrared moisture analyzer for storage batteries, the placement structure includes a telescopic rod rotatably mounted on a measuring plate, a lower placement plate fixedly mounted on the telescopic rod, a lower fixing block fixedly connected to the top of the lower placement plate, a rotating rod rotatably connected to the fixing net, an upper placement plate corresponding to the lower placement plate fixedly mounted on the rotating rod, an upper fixing block slidably mounted on the upper placement plate, and an airflow impeller fixedly sleeved on the outer side of the rotating rod.

[0008] In the aforementioned high-precision infrared moisture analyzer for storage batteries, both the upper fixed block and the rotating rod are U-shaped, and the recesses of the upper fixed block and the rotating rod are perpendicular to each other. The inner walls of both the upper fixed block and the lower fixed block are fixedly fitted with elastic protective layers.

Sealing rings are fixedly installed at the connection between the circulation pipe and the fan blade, as well as at the connection between the connecting pipe and the fixed cylinder.

[0011] In the aforementioned high-precision infrared moisture analyzer for storage batteries, the side wall of the measuring chamber has a vent hole that penetrates the measuring chamber, and a ventilation pipe communicating with the interior of the heating box is fixedly installed on the heating box, with a regulating valve rotatably installed on the ventilation pipe.

[0012] In the aforementioned high-precision infrared moisture analyzer for storage batteries, the connecting tube is a flexible tube, and both the connecting tube and the fixing tube are made of non-metallic materials. Two sealing rings are fixedly installed on the sealing plate, and the positions of the sealing rings correspond to the inner and outer walls of the protective shell, respectively.

[0013] In the aforementioned high-precision infrared moisture analyzer for storage batteries, a one-way airflow valve is fixedly installed inside the connecting tube, and the one-way airflow valve is installed at the connection between the connecting tube and the fixed cylinder.

[0014] Compared with existing technologies, the advantages of this high-precision infrared moisture analyzer for storage batteries are: The air is heated and then circulated to the electrode plates.

Detailed Implementation

[0017] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0018] Reference Figures 1-4 A high-precision infrared moisture analyzer for storage batteries, comprising: Control panel 1 and measuring chamber 2 are fixedly installed together. A fixed cover plate 3 is mounted on control panel 1 by hinge rotation. A measuring plate 4 is fixedly installed inside measuring chamber 2. The purification structure includes a protective shell 5 fixedly mounted on the measuring plate 4. A sealing plate 6 is fixedly snapped onto the protective shell 5. A fixing cylinder 8 is fixedly mounted on the sealing plate 6. A power structure is fixedly mounted inside the fixing cylinder 8. The sealing plate 6 has an opening corresponding to the fixing cylinder 8, and a fixing mesh 7 is fixedly mounted inside the opening. A heating box 11 is fixedly mounted on the inner wall of the measuring chamber 2. An electric heating wire is fixedly mounted on the inner side of the heating box 11 to heat the air. An electric heating wire is fixedly mounted on the heating box 11 by fixing bolts. The filter element 12 usually contains acidic substances on the electrode plate. The acidic gas produced by the evaporation of acidic substances with water is corrosive. The filter element 12 can filter the acidic gas and remove the acidic substances to prevent them from corroding the equipment. A fixed tube 10 is fixedly installed on the filter element 12. A connecting tube 9 is slidably sleeved on the fixed tube 10 and is connected to the inside of the fixed cylinder 8. A circulation tube 13 is fixedly installed on the heating box 11 and is connected to the inside of the protective shell 5. A placement structure is installed on the measuring plate 4. The electrode plate is placed on the placement structure, and the heating box 11 is started to heat the air. At the same time, the air flows through the power structure. The hot air passes through the circulation pipe 13 from the heating box 11 and enters the fixed cylinder 8. Then the hot air heats the electrode plate and carries away the moisture. It enters the fixed pipe 10 through the connecting pipe 9. After the gas passes through the filter element 12, it returns to the heating box 11 to circulate the gas, thereby reducing the energy consumption of the device. At the same time, the airflow also accelerates the evaporation of moisture and improves the measurement speed. Finally, the moisture content of the electrode plate can be determined by measuring the weight change at the detection point of the measuring plate 4. The placement structure includes a telescopic rod 21 rotatably mounted on the measuring plate 4, a lower placement plate 19 fixedly mounted on the telescopic rod 21, a fixed spring fixedly mounted inside the telescopic rod 21 to enable the telescopic rod 21 to extend and retract automatically, a lower fixing block 20 fixedly connected to the top of the lower placement plate 19, a rotating rod 22 rotatably connected to the fixing net 7, an upper placement plate 23 corresponding to the lower placement plate 19 fixedly mounted on the rotating rod 22, an upper fixing block 24 slidably mounted on the upper placement plate 23, and an airflow impeller 25 fixedly sleeved on the outer side of the rotating rod 22. One side wall of the airflow impeller 25 is straight and the other side wall is arc-shaped, thus creating a pressure difference on both sides of the blade, thereby causing the airflow impeller 25 to rotate. Place the bottom end of the electrode plate onto the lower placement plate 23, move the lower fixing block 20 to fix the electrode plate from both sides, and after the sealing plate 6 is closed, the upper fixing block 24 on the upper placement plate 23 further fixes the electrode plate from the front and rear sides. As the airflow flows, the air impeller 25 will rotate, thereby driving the rotating rod 22 fixedly connected to the air impeller 25 to rotate together, causing the upper fixing plate 23 fixedly installed on the rotating rod 22 to rotate accordingly, driving the electrode plate to rotate as well, thereby making the electrode plate more evenly heated. Both the upper fixing block 24 and the rotating rod 22 are U-shaped, and the recesses of the upper fixing block 24 and the rotating rod 22 are perpendicular to each other, so that the electrode plate can be fixed from the left and right sides and the front and back sides at both ends. The inner walls of the upper fixing block 24 and the lower fixing block 20 are fixedly installed with elastic protective layers, which can achieve better fixing effect and avoid damage to the electrode plate. The power structure includes a fixed bracket 26 fixedly installed on the inner wall of the fixed cylinder 8, a motor 16 fixedly installed on the fixed bracket 26, a rotating rod 17 fixedly connected to the output end of the motor 16, and a fan blade 18 fixedly installed on the rotating rod 17. Start the motor 16. The output end of the motor 16 drives the rotating rod 17 to rotate, which causes the fan blade 18 fixedly installed on the rotating rod 17 to rotate, thereby generating an air cylinder and directing the gas inside the protective shell 5 to the fixed cylinder 8. A sealing flange is fixedly installed on the filter element 12. By opening the sealing flange, the filter element 12 can be removed and replaced to prevent the filter element 12 from failing to filter. The filter element 12 is connected to the fixed pipe 10 through the sealing flange. Sealing rings are fixedly installed at the connection between the circulation pipe 13 and the fan blade 18, as well as at the connection between the connecting pipe 9 and the fixed cylinder 8. The sealing flange and the sealing ring have a sealing effect to facilitate the circulation of gas. The side wall of the measuring chamber 2 has a vent hole that passes through the measuring chamber 2. A gas exchange pipe 14 communicating with the interior of the heating box 11 is fixedly installed on the heating box 11. A regulating valve 15 is rotatably installed on the gas exchange pipe 14. Opening the regulating valve 15 can replace the gas in the heating box 11. The replaced gas is discharged from the vent hole. The connecting pipe 9 is a flexible hose, and both the connecting pipe 9 and the fixing pipe 10 are made of non-metallic materials. Non-metallic materials will not be corroded by acidic substances. Two sealing rings are fixedly installed on the sealing plate 6, and the positions of the sealing rings correspond to the inner and outer walls of the protective shell 5, respectively, so as to achieve a sealing effect and prevent acidic gas leakage and further corrosion of the device. A one-way airflow valve is fixedly installed inside the connecting pipe 9 to prevent airflow from flowing back into the protective shell 5, and the one-way airflow valve is installed at the connection between the connecting pipe 9 and the fixed cylinder 8.

[0019] In this invention, the sealing plate 6 is first opened, and the bottom end of the electrode plate is placed on the lower placement plate 23. The lower fixing block 20 is moved to fix the electrode plate from both sides. After the sealing plate 6 is closed, the upper fixing block 24 on the upper placement plate 23 further fixes the electrode plate from the front and rear sides. Then, the heating box 11 and the motor 16 are started. The heating box 11 heats the air, and at the same time, the output end of the motor 16 drives the rotating rod 17 to rotate, causing the fan blade 18 fixedly installed on the rotating rod 17 to rotate accordingly, thereby generating an air cylinder. The gas inside the protective shell 5 flows to the fixed cylinder 8, so that the hot air enters the fixed cylinder 8 from the heating box 11 through the circulation pipe 13. Then, the hot air... The electrode plate is heated, and the moisture is carried away and enters the fixed tube 10 through the connecting pipe 9. After being filtered by the filter element 12, the gas returns to the heating box 11 for gas circulation, which reduces the energy consumption of the device. At the same time, the airflow also accelerates the evaporation of moisture and improves the measurement speed. Finally, the moisture content of the electrode plate can be determined by measuring the weight change at the detection point of the measuring plate 4. During this process, as the airflow flows, the air impeller 25 will rotate, thereby driving the rotating rod 22, which is fixedly connected to the air impeller 25, to rotate together. This causes the upper fixed plate 23, which is fixedly installed on the rotating rod 22, to rotate as well, driving the electrode plate to rotate as well. This makes the electrode plate more evenly heated and avoids deformation and damage to the electrode plate.
