The linkage assembly 5 is arranged so that the same power source can be used for driving the stirring shaft 31 and the sleeve 41 to rotate, thereby reducing the number of devices added on the tank body 1. Because the wall scraping component 4 only needs to work when the tank body 1 discharges mother liquor, the linkage component 5 is set to allow the stirring shaft 31 and the sleeve 41 to be separated, when the tank body 1 discharges mother liquor, the connection between the stirring shaft 31 and the sleeve 41 is established through the linkage component 5, so that the stirring component 3 and the wall scraping component 4 work together, and when the tank body 1 is located in a ring section for stirring mother liquor, the linkage effect of the linkage component 5 is cancelled, the stirring shaft 31 rotates independently, the first scraper 42 and the second scraper 43 stop rotating, further the excessive scraping of the first scraper 42 and the second scraper 43 on the inner wall of the tank body 1 can be avoided, the friction loss of the inner wall of the tank body 1, the first scraper 42 and the second scraper 43 is reduced, and the practicability of the device is improved.

When the stirring shaft 31 and the sleeve 41 need to rotate synchronously, a worker slides the linkage pipe 51 downwards, the linkage pipe 51 drives the inserted link 521 to move downwards, the worker appropriately rotates the stirring shaft 31 to enable the bottom end of the linkage pipe 51 to be opposite to the pipe orifice at the top end of the sleeve 41, then the bottom end of the linkage pipe 51 is inserted into the sleeve 41, when the stirring shaft 31 rotates, the linkage rod can be driven to rotate through the abutting joint of the inner side wall of the sliding groove 522 and the inserted link 521, and the sleeve 41 can rotate along with the linkage pipe 51. Otherwise, the worker slides the linkage pipe 51 upward to separate the bottom end of the linkage pipe 51 from the sleeve 41, so that the stirring shaft 31 can rotate independently.

Referring to fig. 3, a set of locking members 53 is further disposed on the stirring axle 31, each locking member 53 includes a hook 531 and a hanging ring 532, the hook 531 is fixedly connected to a side wall of the stirring axle 31, the hanging ring 532 is disposed above the linkage pipe 51, the hanging ring 532 is disposed at the top end of the linkage pipe 51, when the bottom end of the linkage pipe 51 is separated from the casing 41, the worker continues to move the linkage pipe 51 upward and hook the hanging ring 532 on the hook 531, the position of the linkage pipe 51 is locked, and the linkage pipe 51 can be continuously separated from the casing 41.

Referring to fig. 2 and 3, the top outside the tank body 1 is further provided with a driving assembly 6, the driving assembly 6 is used for driving the stirring shaft 31 to rotate, the driving assembly 6 comprises a worm wheel 61 fixedly sleeved on the upper end of the stirring shaft 31, the top of the tank body 1 is further rotatably connected with a worm 62 meshed with the worm wheel 61, and a driving piece used for driving the worm 62 to rotate, the driving piece is a motor 63, and an output shaft of the motor 63 is coaxially and fixedly connected with the worm 62. After the motor 63 is started to rotate the worm 62, the worm wheel 61 can drive the stirring shaft 31 to rotate under the linkage action of the worm wheel 61 and the worm 62. Since the linkage structure of the worm wheel 61 and the worm 62 has the function of amplifying the torque, the rotation load of the motor 63 can be reduced, and the stirring shaft 31 drives the first scraper 42 and the second scraper 43 to rotate through the sleeve 41, which is also smoother.

Referring to fig. 4, a first edge 421 is arranged on the side of the first scraper 42 for abutting against the top wall of the inner cavity of the tank body 1, and the first edge 421 is used for reducing the area of the residual mother liquor scraped by the first scraper 42, so that the residual mother liquor on the top wall of the inner cavity of the tank body 1 can be scraped by the first scraper 42 more easily. Referring to fig. 5, the second scraping plate 43 is provided with a second edge 431 on the side abutting against the sidewall of the inner cavity of the tank body 1, and the second edge 431 enables the second scraping plate 43 to scrape residual mother liquor on the sidewall of the inner cavity of the tank body 1 more thoroughly. In addition, still link firmly the shelves 432 of vertical setting on the second scraper blade 43, the side wall area of jar body 1 inner chamber is greater than the area of roof, and second scraper blade 43 will scrape and pile up the mother liquor on second scraper blade 43 will be more, and shelves 432 can increase the area that second scraper blade 43 held the accumulational mother liquor of shelves, and the residual mother liquor that makes second scraper blade 43 scrape can be piled up more easily to drop under the action of gravity.

The implementation principle of the embodiment of the application is as follows: when the tank body 1 needs to discharge mother liquor, a worker moves the linkage pipe 51 downwards to enable the bottom end of the linkage pipe 51 to be inserted into the pipe orifice at the top end of the sleeve 41, after the motor 63 is started, the stirring shaft 31 is rotated through the linkage effect of the worm wheel 61 and the worm 62, the stirring shaft 31 can drive the sleeve 41 to rotate through the linkage pipe 51, the two first scraping plates 42 and the two second pipe plates can rotate synchronously, and the top wall and the side wall of the inner cavity of the tank body 1 are scraped respectively. Mother liquor is discharged from the tank body 1 under the condition of being stirred by the stirring shaft 31, the mother liquor is more difficult to remain on the inner wall of the tank body 1, and the mother liquor still remaining on the top wall and the side wall of the inner cavity of the tank body 1 can be scraped by the first scraper 42 and the second scraper 43 and drops into the mother liquor being discharged, so that the aim of reducing material waste is achieved.

When the first scraping plate 42 and the second tube plate are not needed to scrape the inner wall of the tank body 1, a worker slides the linkage pipe 51 upwards to enable the bottom end of the linkage pipe 51 to be separated from the sleeve 41, then the hanging ring 532 on the linkage pipe 51 is hooked on the hanging hook 531 on the stirring shaft 31, the position of the linkage pipe 51 is locked, the stirring shaft 31 cannot drive the first scraping plate 42 and the second scraping plate 43 to rotate when rotating, the situation that the first scraping plate 42 and the second scraping plate 43 scrape the inner wall of the tank body 1 excessively can be avoided, and the friction loss of the inner wall of the tank body 1, the first scraping plate 42 and the second scraping plate 43 is reduced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
