The upper end of the transmission shaft is fixedly provided with a bevel gear 45 which can be meshed with the upper gear ring 6, a rubber ring 44 and a limiting plate 43 are sequentially and fixedly arranged below the bevel gear 45, and the lower end of the transmission shaft is provided with a spur gear through threaded fit.
A movable ring 7 is slidably arranged in the reaction kettle, and internal teeth 72 are arranged in the movable ring 7 and meshed with the spur gear; the scraper 71 is arranged outside the movable ring 7, and the scraper 71 is abutted against the inner wall of the reaction kettle; the scraper 71 is provided with a vertical groove 712, the inner wall of the reaction kettle is vertically provided with a limit bar 35, the limit bar 35 passes through the vertical groove 712, and the upper end and the lower end of the limit bar 35 are also provided with stop blocks.
The working process comprises the following steps:
when the inner wall of the reaction kettle needs to be scraped and cleaned, the motor is started, the output shaft of the motor drives the transmission shaft to circumferentially rotate through the bracket 8, at the moment, the rubber ring 44 on the transmission shaft is located above the clamping ring 811 in the sleeve 81, the limiting plate 43 on the transmission shaft is clamped in the limiting groove 812 of the sleeve 81, namely, the transmission shaft cannot rotate, and the outer gear of the spur gear is meshed with the inner teeth 72 of the movable ring 7 due to the fact that the center of the spur gear is in threaded fit with the transmission shaft, so that when the transmission shaft circumferentially rotates, the spur gear can turn round along the inner teeth 72 of the movable ring 7, and meanwhile, the spur gear also rotates with the step to drive the movable ring 7 to move upwards, and the movable ring 7 scrapes and cleans the inner wall of the reaction kettle through the scraper 71.
When the movable ring 7 moves upwards to a limit position, namely the upper surface of the movable ring 7 is abutted against a stop block at the upper end of a limit bar 35 on the cylinder wall 3, the movable ring 7 stops moving upwards, and the spur gear continues to perform turnover and autorotation movement under the drive of the transmission shaft, so that the transmission shaft starts to move downwards due to the threaded fit between the spur gear until a rubber ring 44 on the transmission shaft is extruded below a clamping ring 811 in the sleeve 81, and after a limit plate 43 on the transmission shaft is separated from a limit groove 812 of the sleeve 81, a bevel gear 45 at the upper end of the transmission shaft is meshed with the upper gear ring 6; at this time, the spur gear continues to perform turnover and autorotation movement, but the transmission shaft starts to perform autorotation movement under the drive of the upper gear ring 6, and due to the relation of the transmission ratio, the autorotation rotation speed of the transmission shaft is greater than that of the spur gear, so that the spur gear can move downwards relative to the transmission shaft, namely, the movable ring 7 is driven to move downwards, and the lower side of the scraper 71 on the movable ring 7 again performs scraping and cleaning operation on the inner wall of the reaction kettle.
Until the movable ring 7 moves to the limit position of the lower end, namely, the lower surface of the movable ring 7 is abutted against the stop block at the lower end of the limit bar 35, the movable ring 7 stops moving, namely, the straight gear stops moving in the vertical direction, the transmission shaft moves upwards under the action of screw thread fit, the rubber ring 44 on the transmission shaft is extruded to the position above the clamping ring 811 in the sleeve 81, and after the bevel gear 45 at the upper end of the transmission shaft is disengaged from the upper gear ring 6, the limit plate 43 on the transmission shaft is clamped in the limit groove 812 below the sleeve 81; so far, the motion of the transmission shaft and the spur gear is restored to the initial state, and one cleaning cycle is completed.
In one embodiment of the application, the handle 31 facilitates the movement and handling of the reactor.
In one embodiment of the present application, the reinforcing plate 32 is usually at the middle lower part of the cylinder wall 3 of the reaction kettle where the cylinder wall 3 is most stressed, so that the reinforcing plate 32 is often added at the middle lower part of the cylinder wall 3 in the prior art, so as to ensure the strength of the cylinder wall 3 of the reaction kettle.
In one embodiment of the application, the center of the upper ring gear 6 is provided with a mounting ring 61.
