In an embodiment of the application, a feeding hole 21 and a discharging hole 22 are formed in the reaction kettle cover 2, a motor is fixedly mounted on the upper surface of the reaction kettle cover 2, an output shaft of the motor is fixedly connected with a stirring frame 5, and the stirring frame 5 extends into the reaction kettle.
The top fixed mounting of the center pin of stirring frame 5 has last ring gear 6, goes up ring gear 6 and is bevel gear to in order to mesh with bevel gear 45, still install support 8 on the center pin of stirring frame 5, support 8 is located 6 below of ring gear, and support 8 is provided with sleeve 81 through the connecting rod connection, and the transmission shaft is rotationally installed in sleeve 81.
The upper end fixed mounting of transmission shaft has bevel gear 45, can with last ring gear 6 meshing, bevel gear 45's below fixed mounting has rubber ring 44 and limiting plate 43 in proper order, and the lower extreme of transmission shaft installs the straight-teeth gear through screw-thread fit.
A movable ring 7 is slidably arranged in the reaction kettle, and internal teeth 72 are arranged inside the movable ring 7 and meshed with a straight gear; a scraper 71 is arranged outside the movable ring 7, and the scraper 71 is abutted against the inner wall of the reaction kettle; a vertical groove 712 is formed in the scraper 71, a limiting strip 35 is vertically arranged on the inner wall of the reaction kettle, the limiting strip 35 penetrates through the vertical groove 712, and stop blocks are further arranged at the upper end and the lower end of the limiting strip 35.
The working process comprises the following steps:
when the wall clearance is scraped to reation kettle's inner wall to needs, starter motor, the output shaft of motor drives the transmission shaft through support 8 and carries out circumferential direction, this moment, epaxial rubber ring 44 of transmission is located the top of the snap ring 811 in sleeve 81, epaxial limiting plate 43 joint of transmission is in sleeve 81's spacing groove 812, the unable rotation of transmission shaft promptly, because straight-teeth gear center department and transmission shaft screw-thread fit, the external gear of straight-teeth gear and the internal tooth 72 meshing of loose ring 7, therefore, when the transmission shaft carries out circumferential direction, the straight-teeth gear can have enough to meet the need along the internal tooth 72 of loose ring 7, the straight-teeth gear still can carry out the rotation in step simultaneously, drive loose ring 7 upward movement, loose ring 7 scrapes the clearance through scraper 71 to reation kettle's inner wall.
When the movable ring 7 moves upwards to the limit position, namely the upper surface of the movable ring 7 abuts against a stop block at the upper end of the limit strip 35 on the cylinder wall 3, the movable ring 7 stops moving upwards, and the spur gear continues to perform turnover and rotation movement under the driving of the transmission shaft, so that the transmission shaft starts moving downwards due to the threaded fit between the transmission shaft and the spur gear until the rubber ring 44 on the transmission shaft is extruded below the snap ring 811 in the sleeve 81, and after the limit plate 43 on the transmission shaft is separated from the limit groove 812 of the sleeve 81, the 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 motions, but the transmission shaft also starts to perform autorotation motions under the drive of the upper gear ring 6, and the autorotation speed of the transmission shaft is greater than that of the spur gear due to the relation of the transmission ratio, so that the spur gear moves 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 scrapes and cleans the inner wall of the reaction kettle again.
Until the movable ring 7 moves to the limit position of the lower end, that is, the lower surface of the movable ring 7 abuts against the stop block at the lower end of the limit strip 35, the movable ring 7 stops moving, that is, the straight gear stops moving in the vertical direction, the transmission shaft moves upwards under the action of thread fit until the rubber ring 44 on the transmission shaft is extruded above the snap 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; at this point, the motion of the transmission shaft and the straight gear is restored to the initial state, and one cleaning cycle is completed.
In one embodiment of the present application, the handle 31 is used for facilitating the moving and carrying of the reaction kettle.
In one embodiment of the present application, the reinforcing plate 32 is usually located at the middle lower part of the cylinder wall 3 where the maximum stress is applied to the cylinder wall 3 of the reaction vessel, so in the prior art, the reinforcing plate 32 is often added at the middle lower part of the cylinder wall 3 to ensure the strength of the cylinder wall 3 of the reaction vessel.
In one embodiment of the present application, a mounting ring 61 is provided centrally of the upper ring gear 6.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
