Referring to Figure 1 , the stirring rod 2000 comprises a central shaft 2100 and a stirring ring, the stirring ring is arranged on the outer periphery of the central shaft 2100, and the stirring ring is spirally arranged along the axis direction of the central shaft 2100; the central shaft 2100 extends upward out of the top cover 1200 and is connected with a driving device 2130, the driving device 2130 is used for driving the central shaft 2100 to rotate axially, and the rotation of the central shaft 2100 drives the stirring ring to rotate synchronously.

[0044] As can be seen from the above, when the stirring rod 2000 is lifted out of the kettle body 1000, the detachable stirring rod 2000 can be easily maintained and cleaned. When the stirring rod 2000 is located in the cavity 1100 of the kettle body 1000, the spiral stirring ring can be polished and cleaned by the polishing device 3000. Figure 1As shown, the polishing device 3000 can extend into the cavity 1100 of the kettle body 1000 from the manhole 1210 of the top cover plate of the kettle body 1000 to polish the spiral stirring ring, without the need to open the cover plate and hoist out the stirring rod 2000, thereby improving the polishing efficiency and reducing the labor cost. The polishing device 3000 can be installed on the kettle body 1000 or the working platform 1300, which is not limited in the embodiment; the kettle body 1000 is also installed on the working platform 1300.

The first clamping plate 3510 and the second clamping plate 3520 are both provided with polishing layers 3530 on the side facing each other. The clamping structure 3500 has a first position and a second position. The support 3300 rotates around the hinge with the vertical plate 3200 to drive the clamping structure 3500 to switch between the first position and the second position. The clamping structure 3500 is folded on the vertical plate 3200 when it is in the first position. The clamping structure 3500 is perpendicular to the vertical plate 3200 when it is in the second position, so as to clean the spiral stirring ring.

[0046] Referring to Figure 2 As shown, in order to facilitate cleaning the outer side wall of the spiral stirring ring, the first clamping plate 3510 is provided with a first protrusion 3511 protruding from the surface thereof on the side facing the second clamping plate 3520. The second clamping plate 3520 is provided with a second protrusion 3521 protruding from the surface thereof on the side facing the first clamping plate 3510. The first protrusion 3511 and the second protrusion 3521 are correspondingly arranged. The first protrusion 3511 and the second protrusion 3521 are both provided with polishing layers 3530 on the side away from the first driving structure 3400. The polishing layers 3530 are preferably detachably connected to the first clamping plate 3510, the second clamping plate 3520, the second protrusion 3521 and the second protrusion 3521, so as to facilitate replacement. The polishing layers 3530 can adopt a structure such as sandpaper. The first protrusion 3511 is preferably detachably connected to the first clamping plate 3510, and the second protrusion 3521 is preferably detachably connected to the second clamping plate 3520, so as to facilitate separate replacement of the first protrusion 3511 and the second protrusion 3521, thereby reducing the maintenance cost.

[0047] In an embodiment of the present application, the first protrusion 3511 is arranged at one end of the first clamping plate 3510 close to the first driving structure 3400, and the second protrusion 3521 is arranged at one end of the second clamping plate 3520 close to the first driving structure 3400. The first protrusion 3511 cooperates with the second protrusion 3521 to grind and clean the outer wall of the outer stirring ring 2010.

[0048] Further, refer to Figure 2 As shown, the stirring ring includes an outer stirring ring 2010 and an inner stirring ring 2020. In order to facilitate the synchronous cleaning of the outer side wall of the inner stirring ring 2020, the first clamping plate 3510 of the embodiment of the present application can refer to Figure 1 As shown, two first protrusions 3511 are provided, and the two first protrusions 3511 are respectively provided in the middle of the first clamping plate 3510 and at one end of the first clamping plate 3510 close to the first driving structure 3400; two second protrusions 3521 are provided corresponding to the first protrusions 3511, and the two second protrusions 3521 correspond one-to-one with the two first protrusions 3511.

[0049] It should be noted that, referring to Figure 2 As shown, since the outer stirring ring 2010 and the inner stirring ring 2020 are connected by multiple shafts, during the rotation of the stirring rod 2000, the first protrusion 3511 set in the middle of the first protrusion 3511 will be obstructed by the shaft. In order to avoid the shaft damaging the first protrusion 3511, the first protrusion 3511 set in the middle of the first protrusion 3511 and the second protrusion 3521 set in the middle of the second protrusion 3521 are preferably made of flexible material, and the first protrusion 3511 set at the end of the first splint 3510 and the second protrusion 3521 set at the end of the second splint 3520 can be made of flexible material or hard material.

[0050] It is conceivable that the first clamping plate 3510 may be provided with four first protrusions 3511, with two first protrusions 3511 disposed at the ends of the first clamping plate 3510, respectively used for polishing the outer and inner sidewalls of the outer stirring ring 2010, and the other two first protrusions 3511 disposed in the middle of the first clamping plate 3510, respectively used for polishing the outer and inner sidewalls of the inner stirring ring 2020.

[0053] In the embodiment of the present application, as shown in Figure 7 、 Figure 9 , the driving motor 3121 is installed at the top end of the base frame 3100, so as to reduce the structure and weight entering the kettle body 1000 through the inspection hole 1210, improve the portability of the polishing device 3000 of the embodiment into the container cavity 1100 of the kettle body 1000, and improve the stability of the polishing device 3000 during use.

[0054] It is conceivable that the second driving structure 3120 is not limited to the driving motor 3121 and the lead screw 3122, but can also be a telescopic motor, a telescopic oil cylinder, a telescopic air cylinder, etc. according to actual conditions.

The vertical plate 3200 is connected with the second mounting seat 3220 through a pin shaft, and the axis line of the pin shaft extends in parallel with the width direction of the vertical plate 3200.

[0056] In the embodiments of the present application, reference is made to Figure 8 As shown, the base frame 3100 is provided with a limiting clamping groove 3130 axially penetrating through the base frame 3100, and the clamping structure 3500 is folded in the limiting clamping groove 3130 when the clamping structure 3500 is in the first position, so as to reduce the height of the clamping structure 3500 protruding from the surface of the base frame 3100, and thus facilitate the polishing device 3000 of the embodiment to enter the cavity 1100 of the kettle body 1000 through the inspection hole 1210.

[0058] The first solution is preferably an acidic solution, so as to facilitate the loosening and stirring of the scale on the surface of the stirring ring, facilitating subsequent polishing and cleaning; the second solution is preferably an alkaline solution, so as to facilitate passivation treatment of the surface of the stirring ring after polishing and cleaning, reducing the loss of the stirring ring due to chemical reaction; the third solution is preferably pure water or silicon oil, so as to clean the stirring rod 2000, facilitating subsequent silicon oil processing. The first, second, third and fourth set time lengths can be set according to actual conditions, and each time length can be equal or unequal, which is not limited in the embodiment.

[0059] Further, in step S5, if the weight of the precipitate is still greater than or equal to the first set value after the set number of cycles, the controller of the silicon oil stirred tank of the embodiment will issue an audible and light alarm. The set number of times can be two, three or the like, which is not limited in the embodiment.

[0060] In the above step S2, the use process of the polishing device 3000 includes the following steps: 1. Open the access hole 1210 of the top cover 1200, place the base frame 3100 of the polishing device 3000 above the access hole 1210, and switch the clamping structure 3500 to the first position; 2. Drive the vertical plate 3200 to descend relative to the base frame 3100, drive the support 3300, the first driving structure 3400 and the clamping structure 3500 into the cavity 1100 of the tank body 1000; 3. When the clamping structure 3500 descends to the first set height, the support 3300 rotates around the hinge of the vertical plate 3200 to drive the clamping structure 3500 to switch from the first position to the second position; 4. The first driving structure 3400 drives the clamping structure 3500 to rotate axially by a set angle to match the helical angle of the helical stirring ring; 5. The first clamping plate 3510 and the second clamping plate 3520 slide away from each other to increase the distance between the first clamping plate 3510 and the second clamping plate 3520; 6. The driving device 2130 drives the central shaft 2100 to rotate forward, and when it is confirmed that the stirring ring enters between the first clamping plate 3510 and the second clamping plate 3520, the first clamping plate 3510 and the second clamping plate 3520 slide towards each other to clamp the stirring ring, and the polishing layer 3530 installed on the first clamping plate 3510 and the second clamping plate 3520 polishes and cleans the stirring ring; 7. During the forward rotation of the central shaft 2100, the clamping structure 3500 gradually descends under the influence of the rotation of the stirring ring; when the clamping structure 3500 descends to the second set height, the first clamping plate 3510 and the second clamping plate 3520 slide away from each other to increase the distance between the first clamping plate 3510 and the second clamping plate 3520; 8. The driving device 2130 drives the central shaft 2100 to rotate in the opposite direction. When the stirring ring is confirmed to have entered between the first clamping plate 3510 and the second clamping plate 3520, the first clamping plate 3510 and the second clamping plate 3520 slide toward each other to clamp the stirring ring. The polishing layers 3530 installed on the first clamping plate 3510 and the second clamping plate 3520 polish and clean the stirring ring. 9. During the reverse rotation of the central shaft 2100, the clamping structure 3500 is gradually lifted by the rotation of the stirring ring. When the clamping structure 3500 reaches the first set height, the first clamping plate 3510 and the second clamping plate 3520 slide away from each other to increase the distance between the first clamping plate 3510 and the second clamping plate 3520. 10. When the central shaft 2100 rotates forward and reverse a set number of times and the clamping structure 3500 rises to the first set height, the clamping structure 3500 switches from the second position to the first position, and the vertical plate 3200 rises relative to the base frame 3100, driving the support 3300, the first driving structure 3400 and the clamping structure 3500 to move above the inspection hole 1210 to complete the grinding of the spiral stirring ring.

The stirring rod cleaning method according to claim 9, characterized in that: The grinding device in step S2 grinds the stirring ring, including the following steps: Open the inspection hole of the top cover, place the base frame of the grinding device above the inspection hole, and switch the clamping structure to the first position; The vertical plate descends relative to the base frame, driving the support, the first driving structure and the clamping structure to enter the cavity; When the clamping structure descends to a first set height, the support rotates about the hinge with the vertical plate to drive the clamping structure to switch from the first position to the second position; The first driving structure drives the clamping structure to axially rotate a set angle to correspond to the spiral angle of the stirring ring; The first clamping plate and the second clamping plate slide away from each other to increase the distance between the first clamping plate and the second clamping plate; The driving device drives the central shaft to rotate in the forward direction. When it is confirmed that the stirring ring enters between the first clamping plate and the second clamping plate, the first clamping plate and the second clamping plate slide toward each other to clamp the stirring ring. The grinding layers installed on the first clamping plate and the second clamping plate grind and clean the stirring ring. During the forward rotation of the central shaft, the clamping structure is gradually lowered by the rotation of the stirring ring; when the clamping structure is lowered to a second set height, the first clamping plate and the second clamping plate slide away from each other to increase the distance between the first clamping plate and the second clamping plate; The driving device drives the central shaft to rotate in the opposite direction. When it is confirmed that the stirring ring enters between the first clamping plate and the second clamping plate, the first clamping plate and the second clamping plate slide toward each other to clamp the stirring ring. The grinding layers installed on the first clamping plate and the second clamping plate grind and clean the stirring ring. During the reverse rotation of the central shaft, the clamping structure is gradually raised by the rotation of the stirring ring; when the clamping structure rises to a first set height, the first clamping plate and the second clamping plate slide away from each other to increase the distance between the first clamping plate and the second clamping plate; When the central axis rotates forward and reverse a set number of times and the clamping structure rises to the first set height, the clamping structure switches from the second position to the first position, and the vertical plate rises relative to the base, driving the support, the first driving structure and the clamping structure to move above the inspection hole to complete the grinding of the stirring ring.
