In the existing technology, after a chemical reaction, the inner wall of the reaction vessel will produce dirt. In order to ensure the sealing of the vessel, the feed inlet of the vessel is designed to be small, which brings great inconvenience to cleaning the dirt on the inner wall of the reaction vessel. It is not only time-consuming and labor-intensive, but may also lead to a reduction in production efficiency.

[0003] Therefore, it is necessary to propose a high-pressure descaling robot for internal use in chemical equipment to solve the above problems. Utility Model Content

[0004] Technical problem to be solved: The purpose of this utility model is to provide a high-pressure descaling robot for the inside of chemical equipment, so as to solve the problem mentioned in the background art that after chemical reaction, the inner wall of the existing reaction tank will produce dirt. In order to ensure the sealing of the tank, the feed port of the tank is designed to be small, which brings great inconvenience to the cleaning of dirt on the inner wall of the reaction tank. It is not only time-consuming and labor-intensive, but may also lead to a reduction in production efficiency.

[0005] Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: A high-pressure descaling robot for internal use in chemical equipment, comprising a descaling device adapted to a reaction vessel. The descaling device includes a drive assembly, a fixing plate bolted to the inlet flange of the reaction vessel, a high-pressure water pump fixedly mounted on the top of the fixing plate, and a screw fixedly mounted vertically on the bottom of the fixing plate. A sliding rod is provided parallel to one side of the screw. The drive assembly is connected to the sliding rod and drives the sliding rod to rotate along the axis of the screw. A sleeve is rotatably fitted on the top of the screw, and a screw cylinder is threadedly fitted on the middle of the screw. A sliding sleeve is slidably fitted on the sliding rod. The system comprises a sliding cylinder and a connecting cylinder. A wireless camera and a high-pressure nozzle are fixedly installed at intervals on the sliding cylinder. Both the sliding cylinder and the connecting cylinder have annular cavities inside. The high-pressure nozzle communicates with the annular cavity of the sliding cylinder. A connecting pipe I is fixedly installed between the sliding cylinder and the screw cylinder, with one end of the connecting pipe I communicating with the annular cavity of the sliding cylinder. A T-shaped through hole is opened inside the screw rod above the sleeve. The vertical section of the T-shaped through hole communicates upwards with the outlet of the high-pressure water pump, and the horizontal section of the T-shaped through hole communicates with the annular cavity of the sleeve. A connecting pipe II is fixedly installed between the sleeve and the connecting cylinder, with one end of the connecting pipe II communicating with the annular cavity of the sleeve. A water supply pipe connecting the two pipes is fixedly installed between the connecting pipe I and the connecting pipe II.

[0006] Preferably, the drive assembly includes a servo motor fixedly mounted on the top of the fixed plate. The output end of the servo motor extends downward to the bottom of the fixed plate and is fixedly fitted with gear II. Gear I is rotatably fitted on the upper part of the screw and a rotating ring is rotatably fitted on the lower part. Gear I and gear II mesh and drive each other. Connecting plates are horizontally fixedly mounted on both the upper and lower ends of the slide rod. The other end of the upper connecting plate is fixedly connected to the bottom of gear I, and the other end of the lower connecting plate is fixedly connected to the rotating ring.

[0007] Preferably, a base plate is fixedly installed at the lower end of the screw, and the base plate abuts against the inner bottom surface of the feed port flange.

[0008] Preferably, the high-pressure nozzle is a three-in-one nozzle, with the three nozzles respectively arranged obliquely upward, obliquely downward, and horizontally.

[0009] Beneficial Effects: Compared with existing technologies, this utility model provides a high-pressure descaling robot for internal use in chemical equipment. This robot has a unique structure. First, a screw and a sliding rod are inserted into the reaction tank, and a fixing plate is fixed to the inlet flange of the reaction tank with bolts. Then, the inlet of the high-pressure water pump is connected to an external water source, and the servo motor and high-pressure water pump are started. The servo motor drives gear II to rotate, which in turn drives gear I to rotate through meshing transmission. This causes the sliding rod to revolve along the axis of the screw. During the rotation of the sliding rod, a wireless camera observes the scale buildup on the inner wall of the reaction tank in real time and transmits the images to an external display for operator monitoring. The high-pressure nozzle rotates under the drive of the sliding rod, performing comprehensive cleaning of the inner wall of the reaction tank. Simultaneously, because the two ends of the connecting pipe I are fixedly connected to the sliding cylinder and the screw cylinder respectively, the rotation of the sliding rod synchronously drives the screw cylinder to rotate. Under the threaded connection between the screw cylinder and the screw, the screw cylinder moves up and down, allowing the high-pressure nozzle to move vertically while revolving, ensuring that every corner of the inner wall of the reaction tank is cleaned.

[0010] This solution uses a servo motor to drive the slide bar to revolve and the screw barrel to move up and down. The high-pressure nozzle can clean the inner wall of the reaction tank from all angles without dead angles, effectively solving the problem that traditional cleaning methods are difficult to completely remove dirt and greatly improving cleaning efficiency. In addition, the real-time image transmission function of the wireless camera allows operators to monitor the dirt on the inner wall of the reaction tank in real time during the cleaning process and adjust the cleaning strategy in a timely manner to ensure that the cleaning effect reaches the best.

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] Example 1: This Example 1 provides a high-pressure descaling robot for use inside chemical equipment. It is a direct improvement on existing descaling devices and has a unique structure. Please refer to [link / reference]. Figure 1-6 As shown, the device includes a descaling device 2 adapted to the reaction vessel 1. The descaling device 2 includes a drive assembly, a fixing plate 21 bolted to the feed inlet flange 11 of the reaction vessel 1, a high-pressure water pump 23 fixedly installed on the top of the fixing plate 21, and a screw 24 fixedly installed vertically on the bottom of the fixing plate 21. The fixing plate 21 has bolt holes for bolt insertion, so that the fixing plate 21 is fixed to the feed inlet flange 11 of the reaction vessel 1 by bolts. A slide rod 210 is provided parallel to one side of the screw 24. The drive assembly is connected to the slide rod 210 and drives the slide rod 210 to rotate along the axis of the screw 24. A sleeve 217 is rotatably fitted on the top of the screw 24, and a screw cylinder 215 is threadedly fitted in the middle of the screw 24.

[0015] The drive assembly includes a servo motor 22 fixedly mounted on the top of the fixed plate 21. Both the servo motor 22 and the high-pressure water pump 23 are electrically connected to an external power source. The output end of the servo motor 22 extends downwards below the fixed plate 21 and is fixedly fitted with a gear II 26. The upper part of the screw 24 is rotatably fitted with a gear I 25, and the lower part is rotatably fitted with a rotating ring 28. Gear I 25 meshes with gear II 26 for transmission. Connecting plates 29 are horizontally fixedly mounted at both the upper and lower ends of the slide rod 210. The other end of the upper connecting plate 29 is fixedly connected to the bottom of gear I 25, and the lower connecting plate... The other end of plate 29 is fixedly connected to rotating ring 28; slide cylinder 212 and connecting cylinder 219 are slidably mounted on slide rod 210, and wireless camera 213 and high-pressure nozzle 214 are fixedly installed on slide cylinder 212 at intervals. Both slide cylinder 212 and sleeve 217 have annular cavities inside; wireless camera 213 is existing equipment, and wireless camera 213 is powered by its internal battery; high-pressure nozzle 214 is a three-in-one nozzle, with the three nozzles set obliquely upward, obliquely downward and horizontally respectively, so as to clean the dirt on the top and bottom surfaces of reaction tank 1.

[0016] The high-pressure nozzle 214 is connected to the annular cavity of the slide cylinder 212. A connecting pipe I 216 is fixedly installed between the slide cylinder 212 and the screw cylinder 215, with one end of the connecting pipe I 216 connected to the annular cavity of the slide cylinder 212. A T-shaped through hole is opened in the screw rod 24 above the sleeve 217. The vertical section of the T-shaped through hole is connected upward to the outlet of the high-pressure water pump 23, and the horizontal section of the T-shaped through hole is connected to the annular cavity of the sleeve 217. The inlet of the high-pressure water pump 23 is connected to the outside. With water supply connected, there are several ways to install the sleeve 217. For example, the sleeve 217 is rotated and mounted on the screw 24 via a bearing, and the annular cavity of the sleeve 217 is opened at the lower part of the sleeve 217; a connecting pipe II 218 is fixedly installed between the sleeve 217 and the connecting sleeve 219, one end of the connecting pipe II 218 is connected to the annular cavity of the sleeve 217, and a water supply pipe 211 connecting the two is fixedly installed between the connecting pipe I 216 and the connecting pipe II 218.

[0017] Working principle: When the operator uses this device to clean the dirt inside the reaction tank 1, firstly, the screw 24 and slide bar 210 are inserted into the reaction tank 1. Then, the fixing plate 21 is fixed to the feed port flange 11 of the reaction tank 1 with bolts. The water inlet of the high-pressure water pump 23 is connected to the external water source. At the same time, the servo motor 22 and the high-pressure water pump 23 are started. The servo motor 22 drives the gear II 26 to rotate, and drives the gear I 25 to rotate through meshing transmission. After the gear I 25 rotates, it drives the slide bar 210 to revolve around the axis of the screw 24. During the rotation of the slide bar 210, the wireless camera 213 can observe the dirt on the inner wall of the reaction tank 1 and send the image to the external display through the wireless network. In addition, during the rotation of the slide bar 210, the high-pressure nozzle 214 will also rotate and clean the dirt on the inner wall of the reaction tank 1.

[0018] Furthermore, since the two ends of the connecting pipe I 216 are fixedly connected to the slide cylinder 212 and the screw cylinder 215 respectively, when the slide rod 210 revolves along the axis of the screw 24, it will synchronously drive the screw cylinder 215 to rotate. Under the action of the threaded connection between the screw cylinder 215 and the screw 24, the screw cylinder 215 will move up and down, so that the high-pressure nozzle 214 can also move vertically while revolving along the axis of the screw 24, thereby cleaning the inner wall of the reaction tank 1 in all directions. When the high-pressure nozzle 214 is working, the high-pressure water pump 23 delivers external water to the annular cavity of the slide cylinder 212 through the T-shaped channel, connecting pipe II 218, water supply pipe 211 and connecting pipe I 216, and sprays it out through the high-pressure nozzle 214. The cleaned dirt is discharged from the discharge port at the bottom of the reaction tank 1 with the water flow.

[0019] Example 2: The difference between Example 2 and Example 1 is as follows: Figure 3 and 6 As shown, a base plate 27 is fixedly installed at the lower end of the screw 24. The base plate 27 abuts against the inner bottom surface of the reaction vessel 1. By setting the base plate 27 at the lower end of the screw 24 and making the base plate 27 abut against the inner bottom surface of the reaction vessel 1, the stability of the screw 24 can be enhanced and the screw 24 can be prevented from shaking.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
