[0002] Chemical equipment is a part of chemical machinery, which includes two parts. The first is chemical machinery, which mainly refers to equipment such as fans, compressors, and various pumps for fluid transportation. Its main components are moving machines, and it is generally called chemical machinery. The second is chemical equipment, which mainly refers to machines with stationary components, such as separation equipment like towers, containers, and reactors. It is sometimes also called non-standard equipment. Among these, the scale treatment device for the inner surface of sodium chlorate crystallizers is widely used in chemical equipment.

[0003] During long-term operation, sodium chlorate crystallizers are prone to developing a hard scale layer on their inner walls due to solution concentration and crystallization. This leads to decreased heat transfer efficiency, increased energy consumption, and even affects production safety. Traditional cleaning methods rely on manual mechanical scraping or chemical cleaning after shutdown, which are inefficient, damage equipment, and pollute the environment. Existing technologies, such as high-pressure water jet or ultrasonic descaling devices, can partially solve the problem, but they are difficult to efficiently treat sodium chlorate crystallizers of different diameters. The existing devices have poor practicality, which in turn reduces the effectiveness and efficiency of the equipment.

[0004] Therefore, those skilled in the art have provided a device for treating scale buildup on the inner surface of a sodium chlorate crystallizer to solve the problems mentioned in the background art. Utility Model Content

The L-shaped plate 6 can be used to fix the drive motor 1, preventing the drive motor 1 from shaking during use and thus affecting the performance of the drive motor 1.

[0026] Two sets of sliding grooves 209 are provided on both the front and back of the I-shaped plate 201. A slider 208 is slidably connected inside each sliding groove 209. A scraper holder 212 is fixedly connected to the outer surface of each slider 208. Two dual-axis servo motors 207 are fixedly connected to the front of the I-shaped plate 201. A protective shell 4 is fixedly connected to the outer surface of each dual-axis servo motor 207. The outer surface of each protective shell 4 is fixedly connected to the outer surface of the I-shaped plate 201. The protective shell 4 can protect the dual-axis servo motor 207 and prevent impurities from entering the interior of the dual-axis servo motor 207 during use, thereby affecting the stability of the dual-axis servo motor 207.

[0027] Each dual-axis servo motor 207 has two threaded rods 206 fixedly connected to its output end. The outer surface of each threaded rod 206 is threadedly connected to the inner wall of the scraper holder 212. A rotating shaft 205 is rotatably connected to the inner wall of the I-beam plate 201. The inner wall of each fixed disc holder 202 is rotatably connected to the outer surface of the rotating shaft 205. The output end of the drive motor 1 is fixedly connected to the top end of the rotating shaft 205. Several identical electric push rods 210 are fixedly connected to the inner wall of each fixed disc holder 202. The outer surface of each electric push rod 210 is fixedly connected to... Each electric push rod 210 has a fixing ring 7, the outer surface of which is fixedly connected to the inner wall of the arc frame 211. The telescopic end of each electric push rod 210 is fixedly connected to the arc frame 211, and the outer surface of each electric push rod 210 is fixedly connected to the fixing ring 7. The outer surface of each fixing ring 7 is fixedly connected to the inner wall of the arc frame 211. By using the fixing ring 7, the connection between the electric push rod 210 and the arc frame 211 can be reinforced, avoiding the problem of breakage at the connection between the electric push rod 210 and the arc frame 211, which would affect the stability of the device. Example

[0028] Please see Figure 1-7 The controller body 204 is fixedly connected to the upper surface of one of the fixed plate frames 202, and a bearing 8 is fixedly connected to the outer surface of the rotating shaft 205. The bottom end of the bearing 8 is fixedly connected to the upper surface of the other fixed plate frame 202. By using the bearing 8, the rotation stability of the rotating shaft 205 can be increased, and the problem of shaking during the rotation of the rotating shaft 205 can be avoided, which would affect the rotation stability of the rotating shaft 205.

[0029] A second battery 203 is fixedly connected to the inner wall of one of the fixed trays 202, and two first batteries 3 are fixedly connected to the inner wall of the I-shaped plate 201. The first batteries 3 are connected to the dual-axis servo motor 207 through wires. The first batteries 3 can provide a relatively stable power supply to the dual-axis servo motor 207, avoiding the problem of power circuit failure during the operation of the dual-axis servo motor 207, which would affect the stability of the device.

The bottom surface of the fixing frame 5 is fixedly connected to the upper surface of the fixing plate 202. The fixing frame 5 can fix the controller body 204 and prevent it from shaking during use, which would affect the circuit transmission effect of the controller body 204. The controller consists of two parts: hardware and software. The hardware mainly includes a central processing unit (CPU) for calculation, input / output (I / O) interfaces for connecting sensors and actuators, memory for storing programs and data, as well as power supply and communication modules. The software includes control algorithm programs and real-time operating systems such as RT. The OS and human-machine interface work together to ensure precise and efficient system control, which is widely used in industrial automation, smart homes, automotive electronics and other fields. The controller is a core device that regulates the operation of the system by processing input signals in real time and generating control commands. Its working principle can be summarized as follows: First, it collects signals from sensors or external inputs such as temperature and speed, and compares them with preset target values ​​to calculate the deviation; then, it uses built-in algorithms such as PID control and logical judgment to analyze the deviation and generate adjustment commands; finally, it drives actuators such as motors and valves through the output interface to adjust the system state, and continuously monitors the effect through closed-loop feedback to achieve dynamic stability. Example

[0031] The working principle of this utility model is as follows: During use, the operator connects the first battery 3 to the dual-axis servo motor 207, and the second battery 203 to the controller body 204 and the drive motor 1. The operator adjusts the position of each I-beam plate 201 and the distance between the arc-shaped frame 211 according to the diameter of the sodium chlorate crystallizer. The device is then placed inside the sodium chlorate crystallizer. The controller body 204 then controls the extension and retraction of the electric push rod 210, which in turn drives the arc-shaped frame 211 to extend and retract. The arc-shaped frame 211 contacts the inner wall of the sodium chlorate crystallizer. The extension and retraction of the electric push rod 210 within the two fixed plate frames 202 fix the device to the inner wall of the sodium chlorate crystallizer. The controller body 204 then controls the dual-axis servo motor 207 to operate. The dual-axis servo motor 207, supported by the I-beam plate 201, drives the threaded rod 206 to rotate. The threaded rod 206 is threadedly connected to the scraper holder 212. Therefore, the rotation of the threaded rod 206 drives the scraper mechanism composed of the scraper holder 212 and the slider 208 to move along the inside of the slide groove 209. When the blade on the surface of the scraper holder 212 contacts the inner wall of the sodium chlorate crystallizer, the operator uses the controller body 204 to control the dual-axis servo motor 207 to stop working. Then, the operator uses the controller body 204 to control the drive motor 1 to work. The drive motor 1 works under the support of two fixed plate frames 202 to drive the rotating shaft 205 to rotate. The rotation of the rotating shaft 205 drives the scraper holder 212 to rotate. The rotation of the scraper holder 212 can scrape and wash the dirt on the inner wall of the sodium chlorate crystallizer, achieving the purpose of cleaning the inner wall of the sodium chlorate crystallizer. This device can clean sodium chlorate crystallizers of different models, thereby improving the applicability and working efficiency of the device.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
