Description

Technical Field

[0001] This utility model relates to the technical field of reactor cleaning and descaling devices, and in particular to a chlorosulfonic acid reactor cleaning and descaling device. Background Technology

[0002] Chlorosulfonic acid is a very important chemical raw material, mainly used in the production of sulfonamide drugs, dyes, pesticides, ion exchange resins, etc. Its production process is usually carried out in a glass-lined reactor. However, during production, side reactions and material residues inevitably occur, forming a hard scale layer on the inner wall of the reactor. Traditional manual cleaning is extremely dangerous, inefficient, has poor cleaning effect, and causes environmental pollution. Therefore, the development and application of automated, enclosed, efficient, and safe specialized cleaning and descaling equipment has become a rigid demand for chlorosulfonic acid and related chemical production enterprises.

[0003] For example, in a class of prior art represented by application number CN201721141878.2, the main structure includes a chemical reactor body, a high-pressure water tank, a motor, a screw, and a cleaning device. The motor is fixed to the upper end of the chemical reactor body, and the screw is connected to the motor through a coupling. The screw extends into the reactor body through an opening at the upper end of the reactor. The cleaning device includes a C-shaped brush, a vertical rod, and a horizontal rod. The C-shaped brush is fixed to one end of the horizontal rod, and the other end of the horizontal rod is fixed to the vertical rod. The surface of the vertical rod is threaded, and the vertical rod is fixed inside the screw through the thread. The vertical rod can move up and down inside the screw through an adjusting nut. The upper end of the chemical reactor body is provided with a water inlet. The cleaning device also includes a connecting hose and a nozzle. One end of the connecting hose is connected to the high-pressure water tank through a valve, and the other end of the connecting hose is connected to the nozzle, which is installed in the water inlet. This utility model provides a chemical reactor cleaning device that is convenient to clean and can achieve all-round cleaning.

[0004] During use, it was found that existing reactor cleaning and descaling devices are not convenient for cleaning reactors of different diameters. Different sizes of scrapers need to be replaced to complete the descaling, which is not very practical. Therefore, there is an urgent need for a chlorosulfonic acid reactor cleaning and descaling device. Utility Model Content

The operating table 01 includes a base 11, which is installed in the work area and has a sliding groove 12. The limiting device 02 includes a motor 21, a bidirectional lead screw 22, a limiting block 23, a limiting block 24, a buffer pad 25, and a buffer pad 26. The motor 21 is installed on the side of the base 11, and the output end of the motor 21 is rotatably connected to the input end of the bidirectional lead screw 22. The limiting blocks 23 and 24 are both installed on the bidirectional lead screw 22 by threaded connection. The limiting blocks 23 and 24 are both slidably installed on the slide groove 12. The buffer pad 25 is installed on the side of the limiting block 23, and the buffer pad 26 is installed on the side of the limiting block 24. The lifting device 03 includes four sets of hydraulic cylinders 31, all of which are installed on the top of the base 11. Each set of hydraulic cylinders 31 is equipped with an output shaft, and the top plate 32 is installed on the top of the output shaft of the four sets of hydraulic cylinders 31. The rotating device 04 includes a second motor 41, a fixed base 42, a connecting base 43, and a mounting shaft 45.

[0019] This utility model discloses a cleaning and descaling device for a chlorosulfonic acid reactor. During operation, the reactor is first placed on top of the base 11. The motor 21 is activated, driving the bidirectional lead screw 22 to rotate. This causes the limiting blocks 23 and 24 to move directionally on the slide groove 12, clamping the reactor with buffer pads 25 and 26. Then, the hydraulic cylinder 31 is activated, causing its output shaft to retract and lower the top plate 32. When the top plate 32 contacts the upper wall of the reactor, the hydraulic cylinder 31 is stopped. Next, the hydraulic cylinder 51 is activated, causing its output shaft to extend, allowing the scraper 52 to move directionally on the guide sleeve 54 via the guide shaft 53. The activation of hydraulic cylinder 3 55 extends the output shaft of hydraulic cylinder 3 55, allowing scraper 2 56 to move directionally on guide sleeve 2 58 via guide shaft 2 57. This causes scraper 1 52 and scraper 2 56 to contact the inner wall of the reactor. Then, the activation of motor 2 41 drives the fixed seat 42 to rotate, simultaneously driving the connecting seat 43 and mounting shaft 45 to rotate, allowing scraper 1 52 and scraper 2 56 to perform descaling on the inner wall of the reactor. At the same time, the activation of power pump 61 opens valve 63, allowing descaling solution to enter through the input end of first pipe 62. The descaling solution flows along second pipe 64 and third pipe 65, and is sprayed onto the inner wall of the reactor through the output end of atomizing nozzle 66, thus performing descaling on the inner wall of the reactor.
