Description

Technical Field

[0001] This utility model relates to the technical field of reactor cleaning equipment, specifically a high-pressure cleaning device with magnetic coupling drive. Background Technology

[0002] After chemical reaction vessels complete production, strong adsorption residues remain on the vessel walls. A common method is to use the cutting force generated by high-pressure water (160-350 atmospheres) to completely remove these residues. However, during the cleaning process, toxic, harmful, flammable, and explosive gases from the reaction vessel can seep into the cleaning equipment and leak out through the high-pressure water jet and motor shaft, potentially causing personal injury, large-scale industrial fires, or explosions.

[0003] Currently, the cleaning of reaction vessels in China's chemical industry generally relies on imported high-pressure cleaning equipment. However, the sealing materials used in imported equipment differ significantly from those used domestically. While some domestic manufacturers have attempted to purchase imported sealing rings, differences in the materials and manufacturing precision of the components mean that domestically produced, imitation-style reaction vessel cleaning equipment, due to the additional lateral force generated by the lifting device compared to imported equipment, rubs against the imported sealing rings, leading to frequent replacements and failing to meet the production cycle of the assembly line. To solve these problems, it is necessary to reduce the interference fit between the sealing assembly and the lifting rod, allowing exhaust gas to enter the cleaning equipment cavity, and fundamentally addressing the motor shaft leakage problem to ensure that exhaust gas remains within the cleaning equipment cavity and does not leak out. Therefore, a non-contact motor torque transmission scheme is proposed, employing the principle of magnetic coupling drive, and this magnetically coupled high-pressure cleaning equipment is designed.

The slider of the ball screw assembly is mounted on the ball screw slider connecting seat by bolts. One side of the ball screw slider connecting seat is tightly connected to the upper and lower lifting rods by bolts and clamping structure.

[0008] A linear bearing is installed on the other side of the ball screw slider connecting seat. The two ends of the linear bearing are limited by snap rings. The ball screw slider guide rod passes through the linear bearing, and the two ends are fixed to the ball screw fixed end mounting seat and the ball screw support end mounting seat respectively with nuts.

[0009] It also includes a high-pressure water cleaning system consisting of upper and lower lifting rods, a high-pressure water hose inside the water drum, a sealing assembly, and a high-pressure water nozzle.

[0010] The bottom cover is connected to the reactor to be cleaned via an outer flange.

[0011] As a preferred embodiment of this utility model, a first dead point sensor is installed at the end of the cylinder near the top cover, and a second dead point sensor is installed at the end of the cylinder near the bottom cover.

[0024] Example: Please refer to Figure 1-5This utility model provides a technical solution: a high-pressure cleaning device with magnetic coupling transmission, comprising a sealed cavity consisting of a water drum 2, a top cover 5, a top flange 6, a cylinder 21, a bottom flange 15, and a bottom cover 16. The device is characterized in that: one leg of the water drum 2 is welded to the water drum connecting plate 1, the water drum connecting plate 1 is welded to the side of the top cover 5, the other leg of the water drum 2 with a high-pressure water hose inside is welded to the end face of the top cover 5, the top flange 6 and the bottom flange 15 are welded to both ends of the cylinder 21 respectively, and the top cover 5 and the top flange 6, and the bottom cover 16 and the bottom flange 15 are all bolted together.

[0025] It also includes a power transmission system consisting of a servo motor and mounting assembly 3, a magnetic coupling input terminal 4, a magnetic coupling output terminal 7, a ball screw assembly 9, a ball screw slider connecting seat 22, a ball screw slider guide rod 10, a ball screw fixed end mounting seat 8, a ball screw support end mounting seat 13, a first dead point sensor 23, and a second dead point sensor 20.

[0026] The top cover 5 of the sealed cavity is provided with threaded holes. Four columns with external threads on the servo motor and mounting assembly 3 are connected to the top cover 5. The magnetic coupling input terminal 4 is connected to the servo motor drive shaft. The top cover 5 is connected to the ball screw fixed end mounting seat 8 inside the sealed cavity by bolts. The power shaft at the upper end of the ball screw assembly 9 is connected to the magnetic coupling output terminal 7. The slider of the ball screw assembly 9 is mounted on the ball screw slider connecting seat 22 by bolts. One side of the ball screw slider connecting seat 22 is tightly connected to the upper and lower lifting rods 12 by bolts and clamping structure.

[0027] A linear bearing 11 is installed on the other side of the ball screw slider connecting seat 22. The two ends of the linear bearing 11 are limited by snap rings. The ball screw slider guide rod 10 passes through the linear bearing 11 and is fixed at both ends with nuts to the ball screw fixed end mounting seat 8 and the ball screw support end mounting seat 13, respectively.

[0028] It also includes a high-pressure water cleaning system consisting of an upper and lower lifting rod 12, a high-pressure water hose inside the water drum 2, a sealing assembly 14, and a high-pressure water nozzle 18. Both ends of the upper and lower lifting rod 10 are provided with internal threads. One end of the upper and lower lifting rod 10 is connected to the connector of the high-pressure water hose inside the water drum 2. The other end of the upper and lower lifting rod 10 passes through the hole in the ball screw support end mounting seat 13 and the sealing assembly 14, and extends out of the sealed cavity to connect with the high-pressure water nozzle 18. The bottom cover 16 is connected to the reactor to be cleaned through the outer flange 19.

[0029] A first dead point sensor 23 is installed at the end of the cylinder 21 near the top cover 5, and a second dead point sensor 20 is installed at the end of the cylinder 21 near the bottom cover 16; a plug 17 is also installed on the bottom cover 16; a high-pressure water connector 24 is provided on the water drum 2, and a water drum hose connector 25 is also installed on the cylinder 21; the plug 17 is connected to the bottom cover 16 by threads.

[0030] Servo motor 3 drives magnetic coupling input terminal 4 and output terminal 7 to rotate. Output terminal 7 drives ball screw assembly 9 to rotate, so that the slider of ball screw assembly 9 drives the up and down lifting rod 12 to drag the high-pressure water hose in water drum 2. It moves up and down between the stroke of the first dead point sensor 23 and the second dead point sensor 20. High-pressure water of 160-350 atmospheres is sprayed out from nozzle 18 to clean the dirt attached to the reaction vessel. At the same time, it effectively controls the toxic, harmful, flammable and explosive gases in the container to be cleaned within the sealed cavity. After cleaning is completed, the plug 17 on the bottom cover is unscrewed and the waste gas is discharged into a special treatment pool.

[0031] The high-pressure cleaning equipment has a completely sealed structure, which can isolate toxic, harmful, flammable and explosive gases in the chemical reaction vessel to be cleaned within the sealed cavity of the cleaning equipment during the cleaning process. One leg of the water drum 2 is welded to a water drum connecting plate 1, and the water drum connecting plate 1 is welded to the side of the top cover 5. The other leg of the water drum 2, through which a high-pressure water hose passes, is welded to the end face of the top cover 5. The top flange 6 and the bottom flange 15 are welded to the two ends of the cylinder, respectively. The top cover 5 and the top flange 6, and the bottom cover 16 and the bottom flange 15 are all bolted together. This structure ensures that during the cleaning process, the gas from the reaction vessel will not leak out of the sealed container of the equipment from the hole where the water drum 2 hose passes through the top cover 5.

[0032] The power source for the high-pressure water nozzle 18 that moves up and down on the cleaning equipment is to transmit torque to the magnetic coupling input terminal 4 via the servo motor 3 shaft. The magnetic coupling input terminal 4, through the top cover 5 of the sealed cavity, uses magnetic force to transmit torque to the magnetic coupling output terminal 7, which drives the screw of the ball screw assembly 9, which is fastened to the magnetic coupling output terminal 7, to rotate. This causes the slider of the ball screw assembly 9 to move up and down, which in turn drives the upper and lower lifting rod 12, which is bolted to its mounting base 22. The upper and lower lifting rod 12 is a hollow tube with threads on both sides. One end is connected to the high-pressure water hose of the water drum 2, and the other end is connected to the high-pressure water nozzle 18. After the outer flange 19 is bolted to the reactor, the servo motor 3 can be started to clean the reactor.

[0033] Working Principle: A high-pressure cleaning device with magnetic coupling transmission. When the servo motor 3 is started to clean the reaction vessel, the power is transmitted from the motor 3 shaft through the magnetic coupling input terminal 4, through the top cover of the sealed cavity, to the magnetic coupling output terminal 7 in a non-contact manner. This drives the ball screw assembly 9 to rotate. Under the action of the ball screw slider guide rod 10, the slider of the ball screw assembly 9 converts the rotational motion of the screw into up-and-down linear motion, thereby driving the up-and-down lifting rod 12 tightly connected to the ball screw slider connecting seat 22. The reciprocating lifting rod 12 is a hollow tube with threads at both ends. One end connects to the high-pressure water hose inside the water drum 2, and the other end passes through the sealing assembly 14 and connects to the high-pressure water nozzle 18. Depending on the diameter of the reactor, high-pressure water at 160-350 atmospheres is ejected from all four sides of the nozzle 18. The powerful water cutting force cleans away the dirt that has solidified and adhered to the reactor. Throughout the cleaning process, toxic, harmful, flammable, and explosive gases inside the reactor are confined within the sealed cavity of the cleaning equipment and cannot leak out. After cleaning, simply move the cleaning equipment to a dedicated waste gas treatment area, unscrew the plug 17 on the bottom cover, and discharge the waste gas into a dedicated treatment pool.

[0034] The above embodiments merely illustrate the implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
