[0002] Chemical pressure vessels are equipment used in chemical production processes that can withstand a certain pressure and store or process chemical media. Chemical pressure vessels have a variety of shapes, the most common of which are cylindrical and spherical. The cylindrical structure is relatively simple to make and is easy to install various internal parts and connecting pipes. It is widely used in the chemical industry. The manufacturing process of chemical pressure vessels is a complicated process, which requires rolling the cylinder and then welding the joints.

[0003] The purpose of grinding the joints of the pressure vessel shell is to improve the surface quality, meet the anti-corrosion requirements and meet the appearance requirements. Commonly used grinding equipment includes hand-held angle grinders, straight grinders and automatic grinding equipment. Grinding tools include grinding wheels, grinding belts and grinding discs.

[0026] 4. The present invention sets an auxiliary component. Before grinding, the direction of the roller is adjusted according to the grinding direction to ensure that the roller can roll on the surface of the container, thereby assisting the grinding of the grinding plate and avoiding the shaking of the container during grinding. During circumferential grinding, the roller can roll on the surface of the joint after grinding to roll off the grinding waste chips to avoid residual waste chips, thereby avoiding excessive waste chips on the surface of the container causing excessive waste chips to adhere to the grinding plate, avoiding the reduction of the roughness of the grinding plate, and maintaining the grinding effect.

[0027] 5. The present invention sets a driving component to continuously input pulse signals to the stepper motor, which eventually drives the grinding plate to rotate continuously to complete the grinding of the circumferential seam. A certain number of pulse signals are input to the stepper motor to drive the rotating shaft to rotate a certain angle, and then a reverse pulse signal is input to reverse the rotating shaft, thereby finally realizing the reciprocating motion of the grinding plate.

Similarly, when grinding in the circumferential direction, the driving telescopic rod 351 is continuously reciprocated to realize the complete grinding of the circumferential seams with larger thickness.

[0054] The fixing assembly 36 includes a hollow rod 361, which is arranged inside the cylinder 31 and passes through the bottom plate 1. The surface of the hollow rod 361 is fixedly connected to the inner side surface of the bottom plate 1, and the end of the hollow rod 361 located at the bottom of the bottom plate 1 is through-set. The surface of the hollow rod 361 located at the bottom of the bottom plate 1 is fixedly connected to the inner side surface of the sleeve plate 356 away from the stepping motor 355. A fixing ring 362 is fixedly connected to the surface of the hollow rod 361, and a fixing plate 363 is fixedly connected to the outer side surface of the fixing ring 362. A driving ring 364 is fixedly connected to the end of the fixing plate 363 away from the fixing ring 362. The inner side surface of the driving ring 364 is slidably connected to the surface of the hollow rod 361, driving the driving ring 364 to move, driving the fixing plate 363 to deform, and abutting against the inner side surface of the container, thereby fixing the inner wall of the container.

[0055] A groove 365 is provided on the surface of the hollow rod 361 located inside the cylinder 31, and an inner cone plate 367 is provided on the side of the cylinder 31 close to the bottom plate 1. The inner side surface of the inner cone plate 367 is fixedly connected to the surface of the hollow rod 361, and the groove 365 is provided on the side of the inner cone plate 367 away from the bottom plate 1, and a sliding ring 368 is fixedly connected to the outer side surface of the inner cone plate 367. The inner side surface of the sliding ring 368 is slidingly connected to the surface of the driving telescopic rod 351. The polished waste falls to the bottom plate 1 and is then received by the inner cone plate 367. The waste slides along the surface of the inner cone plate 367, enters the groove 365, and finally leaves along the hollow inner cavity of the hollow rod 361, thereby realizing the collection of the polished waste and facilitating the centralized recycling of the waste. The end through which the hollow rod 361 passes can be connected to an air pump to extract the waste to avoid blockage.

[0056] When in use, the container is inserted from the top of the cylinder 31, the driving ring 364 is driven to move, the fixing plate 363 is deformed, and the inner side of the container is pressed against, so as to fix the inner wall of the container, and the telescopic rod 332 is adjusted and extended, and the universal joint 333, the fixing seat 334, and the grinding plate 32 are driven to move. The grinding plate 32 moves, and the connecting plate 3310, the spring plate 339, and the ring plate 337 are driven to move. The ring plate 337 slides on the surface of the slide cylinder 335, and the spring 338 is deformed, so as to limit and buffer the adjustment, so that the grinding plate 32 is stably attached to the container. When circumferential grinding, the pulse signal is continuously input to the stepping motor 355, so that the rotating shaft 354 is continuously rotated, the gear 353 is continuously rotated, and the gear 35 3 drives the gear ring 352 to rotate continuously, drives the driving telescopic rod 351 to rotate circumferentially along the gear ring 352, and finally drives the grinding plate 32 to rotate continuously, and continuously makes the driving telescopic rod 351 reciprocate and retract, so as to complete the grinding of the circumferential joint. When grinding in the height direction, the driving telescopic rod 351 is started, and the driving telescopic rod 351 drives the cylinder 31 to rise and fall, and finally drives the grinding plate 32 to rise and fall, and at the same time inputs a certain number of pulse signals to the stepping motor 355, drives the rotating shaft 354 to rotate a certain angle, and then inputs a reverse pulse signal, and the rotating shaft 354 reverses, drives the gear 353 to reciprocate, and the gear ring 352 and the driving telescopic rod 351 reciprocate, and finally drives the grinding plate 32 to rise and fall while reciprocating, so as to realize the grinding of the entire joint.
