Description

Technical Field

[0001] This utility model relates to the technical field of dilute sulfuric acid concentration equipment, and in particular to a dilute sulfuric acid concentration equipment. Background Technology

[0002] Dilute sulfuric acid is widely generated as an intermediate product or waste liquid in many industrial sectors such as chemical engineering, metallurgy, and pharmaceuticals. Due to its low concentration, direct discharge of dilute sulfuric acid not only causes serious environmental pollution but also leads to a significant waste of sulfur resources. Therefore, concentrating dilute sulfuric acid to increase its concentration for recycling and reuse has become a crucial issue urgently needing to be addressed in current industrial production.

[0003] Currently, existing technologies for concentrating dilute sulfuric acid mainly include evaporation concentration, membrane separation, and ion exchange. Among these, evaporation concentration is widely used due to its relatively simple operation and wide applicability. However, traditional evaporation concentration equipment suffers from several problems during actual operation. Uneven mixing of the solution during concentration leads to frequent localized overheating, affecting concentration efficiency and potentially causing sulfuric acid decomposition or equipment corrosion due to excessively high local temperatures. Poor material circulation within the equipment results in significant variations in the residence time of dilute sulfuric acid during concentration, leading to large fluctuations in the final product concentration, making it difficult to meet the precise sulfuric acid concentration requirements of industrial production. Therefore, a dilute sulfuric acid concentration treatment device is proposed to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dilute sulfuric acid concentration treatment device, which solves the problems of uneven solution mixing during the concentration process, leading to frequent local overheating, which not only affects the concentration efficiency but may also cause sulfuric acid decomposition or equipment corrosion due to excessively high local temperatures; and poor material circulation inside the equipment, resulting in large differences in the residence time of dilute sulfuric acid during the concentration process, leading to large fluctuations in the final product concentration, making it difficult to meet the precise sulfuric acid concentration requirements of industrial production.

[0008] A further improvement is that the stirring assembly includes a drive motor, the bottom output end of the drive motor is fixedly connected to a rotating shaft, and the outer wall of the rotating shaft is fixedly connected to a closed frame.

[0009] A further improvement is that the motor is fixedly installed on the top of the fixed plate, the perforated connecting rod is provided with limit holes at equal intervals, and the fixed round block is sleeved on the inner wall of the limit hole; the bottom of the perforated connecting rod is hinged to the sliding sleeve through a pin, so the reciprocating motion of the perforated connecting rod can drive the sliding sleeve to move up and down, and the air rod fixedly connected to the bottom of the sliding sleeve also slides up and down on the outer wall of the lower section of the connecting bend.

[0010] A further improvement is that the feeding pipe is connected to the inner wall of the fixed plate, and the discharge pipe is connected to the inner wall of the hemispherical cover; during the operation of the equipment, the hemispherical cover in the connecting assembly protects the bottom of the equipment body, while the support legs provide stable support for the entire equipment, ensuring that the equipment will not shake or tip over during operation.

[0011] A further improvement is that the drive motor is fixedly installed at the top of the middle section of the fixed plate, the rotating shaft is rotatably connected to the inner wall of the top of the equipment body, and the circumference of the closed frame is set on the outer wall of the rotating shaft; the circumference of the closed frame is fixedly connected to the outer wall of the rotating shaft, and the rotation of the rotating shaft will drive the closed frame to make circumferential motion inside the equipment body; the rotation of the closed frame plays a role in fully stirring the dilute sulfuric acid in the equipment body, so that the dilute sulfuric acid can be evenly mixed inside the equipment, avoiding the situation of local concentration being too high or too low, laying a good foundation for subsequent concentration treatment.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Uneven mixing of the solution during concentration leads to frequent localized overheating, affecting concentration efficiency and potentially causing sulfuric acid decomposition or equipment corrosion due to excessively high local temperatures. Poor material circulation within the equipment results in significant variations in the residence time of dilute sulfuric acid during concentration, leading to large fluctuations in the final product concentration and making it difficult to meet the precise sulfuric acid concentration requirements of industrial production. This embodiment provides a dilute sulfuric acid concentration treatment device; please refer to... Figures 1-5This embodiment provides a dilute sulfuric acid concentration treatment device, including a device body 1, a connecting mechanism 2, an adhesive layer 101 on the inner side of the device body 1, a high-silicon alloy layer 102 on the inner side of the adhesive layer 101, a connecting component 21 at the upper and lower ends of the device body 1, a stirring component 22 in the middle section of the device body 1, and a driving component 23 on the right section of the device body 1; the driving component 23 includes a motor 231, and a drive shaft 232 is fixedly connected to the output end of the right section of the motor 231. A rotating plate 233 is fixedly connected to the outer end of the drive shaft 232. A fixed round block 234 is fixedly connected to the bottom of the outer end of the rotating plate 233. A perforated connecting rod 235 is sleeved on the outer wall of the fixed round block 234. A sliding sleeve 237 is hinged to the bottom of the perforated connecting rod 235 through a pin 236. An air rod 238 is fixedly connected to the bottom of the sliding sleeve 237. A connecting bend 239 is slidably connected to the outer wall of the lower section of the air rod 238. A filter plate 2310 is fixedly installed on the inner wall of one end of the bottom of the connecting bend 239. A connecting valve pipe 2311 is connected to the bottom of the connecting bend 239.

[0027] In this embodiment, the motor 231 is fixedly mounted on the top of the fixed plate 211. After the motor 231 is started, its right output end drives the drive shaft 232 to rotate. The rotation of the drive shaft 232 then drives the rotating plate 233 fixed at its outer end to rotate. The fixed circular block 234 at the bottom of the outer end of the rotating plate 233 is sleeved on the inner wall of the limiting hole of the perforated connecting rod 235. As the rotating plate 233 rotates, the fixed circular block 234 drives the perforated connecting rod 235 to reciprocate. The bottom is hinged to the sliding sleeve 237 via a pin 236. Therefore, the reciprocating motion of the perforated connecting rod 235 can drive the sliding sleeve 237 to move up and down. The air rod 238, which is fixedly connected to the bottom of the sliding sleeve 237, also slides up and down on the outer wall of the lower section of the connecting bend 239. The up and down sliding of the air rod 238 inside the connecting bend 239 changes the internal volume of the connecting bend 239, thereby generating a change in air pressure. When the air rod 238 moves upward, the space inside the connecting bend 239 increases, and the air pressure changes. As the pressure decreases, the agitated dilute sulfuric acid inside the main body 1 enters the connecting bend 239 through one end of the middle section under the action of the pressure difference. During the process of dilute sulfuric acid entering the connecting bend 239, the filter plate 2310 fixedly installed on the inner wall of the bottom end of the connecting bend 239 filters the dilute sulfuric acid, removing any impurities it may contain, and ensuring the purity of the dilute sulfuric acid entering the subsequent process. When the air rod 238 moves downward, the space inside the connecting bend 239 decreases and the air pressure increases. The dilute sulfuric acid filtered by the filter plate 2310 will enter the connecting valve pipe 2311 through the bottom end of the connecting bend 239 under the action of air pressure. Since the bottom end of the connecting valve pipe 2311 is connected to the inner wall of the discharge pipe 215, the dilute sulfuric acid will eventually flow into the discharge pipe 215 through the connecting valve pipe 2311. In this process, the reciprocating motion of the air rod 238 realizes the circulation of dilute sulfuric acid inside the equipment, further promoting the uniform mixing and concentration of dilute sulfuric acid.

[0028] Furthermore, the motor 231 is fixedly installed on the top of the fixed plate 211, the connecting rod 235 with holes is provided with limit holes at equal intervals, and the fixed round block 234 is sleeved on the inner wall of the limit hole; one end of the middle section and one end of the bottom section of the connecting bend 239 are connected and set on the inner wall of the right side of the equipment body 1, and one end of the bottom section of the connecting valve pipe 2311 is connected and set on the inner wall of the discharge pipe 215.

[0029] Furthermore, the up-and-down sliding of the air rod 238 within the connecting bend 239 changes the internal volume of the connecting bend 239, thereby generating a change in air pressure. When the air rod 238 moves upward, the space within the connecting bend 239 increases, and the air pressure decreases. The dilute sulfuric acid stirred within the equipment body 1 will enter the connecting bend 239 through one end of the middle section under the action of the air pressure difference. During the process of dilute sulfuric acid entering the connecting bend 239, the filter plate 2310 fixedly installed on the inner wall of one end of the bottom of the connecting bend 239 will filter the dilute sulfuric acid, removing any impurities it may contain, and ensuring the purity of the dilute sulfuric acid entering subsequent processes.

[0030] Example 2

[0031] Based on Embodiment 1, the connecting component 21 includes a fixing plate 211 fixedly installed on the top of the device body 1, a feeding pipe 212 connected to the top left side of the device body 1, a hemispherical cover 213 fixedly connected to the bottom outer wall of the device body 1, a support leg 214 fixedly connected to the bottom of the hemispherical cover 213, and a discharge pipe 215 connected to the bottom of the device body 1; the stirring component 22 includes a drive motor 221, a rotating shaft 222 fixedly connected to the bottom output end of the drive motor 221, and a closing frame 223 fixedly connected to the outer wall of the rotating shaft 222.

[0032] In this embodiment, before the equipment starts operating, the dilute sulfuric acid to be processed is added into the equipment body 1 through the feeding pipe 212 in the connecting component 21. After feeding, the stirring component 22 starts working, and the drive motor 221 starts. Its bottom output end drives the rotating shaft 222 to rotate. Since the closed frame 223 is circumferentially fixed to the outer wall of the rotating shaft 222, the rotation of the rotating shaft 222 will drive the closed frame 223 to make circumferential motion inside the equipment body 1. The rotation of the closed frame 223 plays a role in fully stirring the dilute sulfuric acid in the equipment body 1, so that the dilute sulfuric acid can be evenly mixed inside the equipment, avoiding local concentrations that are too high or too low, laying a good foundation for subsequent concentration treatment. During the operation of the equipment, The hemispherical cover 213 in the connecting component 21 protects the bottom of the equipment body 1, while the support leg 214 provides stable support for the entire equipment, ensuring that the equipment will not shake or tip over during operation. After a series of stirring, circulation and concentration processes, the final concentrated sulfuric acid will be discharged from the equipment through the discharge pipe 215, completing the entire dilute sulfuric acid concentration process. In the entire equipment, the connecting component 21 provides the installation foundation and structural support for other components, the stirring component 22 ensures the uniform mixing of dilute sulfuric acid, and the drive component 23 realizes the circulation and concentration of dilute sulfuric acid through the synergistic action of various components. The components cooperate closely with each other to complete the efficient concentration of dilute sulfuric acid.

[0033] Furthermore, the feeding pipe 212 is connected to the inner wall of the fixed plate 211, and the discharge pipe 215 is connected to the inner wall of the hemispherical cover 213; the drive motor 221 is fixedly installed on the top of the middle section of the fixed plate 211, the rotating shaft 222 is rotatably connected to the inner wall of the top of the equipment body 1, and the closed frame 223 is circumferentially arranged on the outer wall of the rotating shaft 222.

[0034] Furthermore, the rotation of the closed frame 223 fully stirs the dilute sulfuric acid inside the equipment body 1, ensuring uniform mixing and preventing localized high or low concentrations, thus laying a good foundation for subsequent concentration treatment. During equipment operation, the hemispherical cover 213 in the connecting component 21 protects the bottom of the equipment body 1, while the support legs 214 provide stable support for the entire equipment, ensuring that the equipment will not shake or tip over during operation. After a series of stirring, circulation, and concentration processes, the final concentrated sulfuric acid is discharged from the equipment through the discharge pipe 215, completing the entire dilute sulfuric acid concentration process.

[0035] Working Principle: Before the equipment starts operating, the dilute sulfuric acid to be treated is added into the equipment body 1 through the feeding pipe 212 in the connecting component 21. After feeding, the stirring component 22 starts working, and the drive motor 221 starts. Its bottom output end drives the rotating shaft 222 to rotate. Since the closed frame 223 is circumferentially fixed to the outer wall of the rotating shaft 222, the rotation of the rotating shaft 222 will drive the closed frame 223 to make circumferential motion inside the equipment body 1. The rotation of the closed frame 223 plays a role in fully stirring the dilute sulfuric acid in the equipment body 1, so that the dilute sulfuric acid can be evenly mixed inside the equipment, avoiding local concentrations that are too high or too low, laying a good foundation for subsequent concentration treatment. The adhesive layer 101 is located between the equipment body 1 and the high silicon alloy layer 102. Its core function is to firmly connect the basic structure of the equipment body with the inner high silicon alloy layer, ensuring that the two layers will not peel off or loosen during equipment operation. To ensure the overall stability of the equipment structure, the elasticity or toughness of the material itself can buffer the deformation differences caused by temperature changes and mechanical stress, reducing structural damage due to insufficient material compatibility. The high-silicon alloy layer 102 has excellent resistance to sulfuric acid corrosion, especially to both dilute and concentrated sulfuric acid. Its inner side is in direct contact with dilute sulfuric acid, effectively resisting corrosion of the equipment's inner wall by dilute sulfuric acid during the concentration process, including high temperature and high concentration stages, significantly extending the equipment's service life. The adhesive layer 101 and the high-silicon alloy layer 102 form a synergistic "protection-connection" system: the adhesive layer provides a stable adhesion base for the high-silicon alloy layer, ensuring its continuous anti-corrosion function; the high-silicon alloy layer acts as the "first line of defense" against sulfuric acid corrosion in direct contact with the medium, while the buffering and sealing effects of the adhesive layer further enhance the reliability of this protective system, jointly improving the equipment's adaptability to the dilute sulfuric acid concentration environment.

[0036] While the stirring assembly 22 is working, the drive assembly 23 also starts synchronously. The motor 231 is fixedly mounted on the top of the fixed plate 211. After the motor 231 starts, its right output end drives the drive shaft 232 to rotate. The rotation of the drive shaft 232 then drives the rotating plate 233 fixed at its outer end to rotate. The fixed round block 234 at the bottom of the outer end of the rotating plate 233 is fitted into the inner wall of the limiting hole of the perforated connecting rod 235. As the rotating plate 233 rotates, the fixed round block 234 drives the perforated connecting rod 235 to rotate. 5. Reciprocating motion; the bottom of the perforated connecting rod 235 is hinged to the sliding sleeve 237 via a pin 236. Therefore, the reciprocating motion of the perforated connecting rod 235 can drive the sliding sleeve 237 to move up and down. The air rod 238, which is fixedly connected to the bottom of the sliding sleeve 237, also slides up and down on the outer wall of the lower section of the connecting bend 239. The up and down sliding of the air rod 238 inside the connecting bend 239 will change the internal volume of the connecting bend 239, thereby generating a change in air pressure. When the air rod 238 moves upward, the connecting bend 23... As the space inside the device increases and the air pressure decreases, the dilute sulfuric acid stirred inside the device body 1 will enter the connecting bend 239 through one end of the middle section under the action of the air pressure difference. During the process of dilute sulfuric acid entering the connecting bend 239, the filter plate 2310 fixedly installed on the inner wall of the bottom end of the connecting bend 239 will filter the dilute sulfuric acid, remove any impurities it may contain, and ensure the purity of the dilute sulfuric acid entering the subsequent process. When the air rod 238 moves downward, the space inside the connecting bend 239 decreases and the air pressure increases. The dilute sulfuric acid filtered by the filter plate 2310 will enter the connecting valve pipe 2311 through the bottom end of the connecting bend 239 under the action of air pressure. Since the bottom end of the connecting valve pipe 2311 is connected to the inner wall of the discharge pipe 215, the dilute sulfuric acid will eventually flow into the discharge pipe 215 through the connecting valve pipe 2311. In this process, the reciprocating motion of the air rod 238 realizes the circulation of dilute sulfuric acid inside the device, further promoting the uniform mixing and concentration of dilute sulfuric acid.

[0037] During equipment operation, the hemispherical cover 213 in the connecting component 21 protects the bottom of the equipment body 1, while the support legs 214 provide stable support for the entire equipment, ensuring that the equipment will not shake or tip over during operation. After a series of stirring, circulation, and concentration processes, the final concentrated sulfuric acid will be discharged from the equipment through the discharge pipe 215, completing the entire dilute sulfuric acid concentration process. In the entire equipment, the connecting component 21 provides the installation foundation and structural support for other components, the stirring component 22 ensures the uniform mixing of dilute sulfuric acid, and the drive component 23 realizes the circulation and concentration of dilute sulfuric acid through the synergistic action of various components. The components cooperate closely with each other to complete the efficient concentration of dilute sulfuric acid.
