DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all.

[0022] The special mixing tank for sodium ion battery positive electrode material in the present application is similar to the existing mixing tank structure. For example, a patent with publication number CN220345700U discloses a special mixing tank for sodium ion battery positive electrode material. The main improvement of the present application is that the sealing plate 5 can be rotated under the action of the driving mechanism 6, so that the upper end of the mixing tank can be sealed or opened as needed, so that the sealing tank has the advantages of both open-type mixing tanks and sealed mixing tanks. Figures 1 to 5As shown, when it is needed to open the sealing plate 5 and add raw materials into the tank body 1, the multi-stage electric telescopic rod 607 can be driven, and the multi-stage electric telescopic rod 607 gradually shortens, so that the sealing plate 5 is given a pulling force, and the sealing plate 5 rotates with the L-shaped connecting block 403 and the connecting rod 402 on the limiting block 401, in the process of upward rotation of the sealing plate 5, the output end of the multi-stage electric telescopic rod 607 rotates with the second rotating shaft 606, and the base of the multi-stage electric telescopic rod 607 rotates with the first rotating shaft 603, so as to adjust the angle of the multi-stage electric telescopic rod 607, and according to the opposite operation, the sealing plate 5 can be re-covered on the upper end of the tank body 1, and the upper end of the tank body 1 is sealed, after the upper end of the tank body 1 is sealed, the inside of the tank body 1 can be observed through the glass window 7, when the lower surface of the glass window 7 adheres too much raw materials, dust and the like, the rotating disc 802 can be rotated, so that the third rotating shaft 801 and the supporting rod 803 are rotated, so that the rubber strip 804 on the supporting rod 803 cleans the lower surface of the glass window 7.

[0023] As Figure 3 shown, the connecting mechanism 4 comprises four limiting blocks 401 fixed on the supporting plate 2, four limiting blocks 401 are rotatably connected with the connecting rod 402, the connecting rod 402 is fixedly connected with the L-shaped connecting block 403, and the sealing plate 5 is fixedly connected with the front end lower surface of the L-shaped connecting block 403.

[0024] Specifically, the sealing plate 5 is fixedly connected with the front end lower surface of the L-shaped connecting block 403, and after the multi-stage electric telescopic rod 607 is driven, the sealing plate 5 can rotate with the L-shaped connecting block 403 and the connecting rod 402 in the limiting block 401.

[0025] As Figure 1 shown, the driving mechanism 6 is divided into two groups, the outer two are a group, the middle two are a group, the number of each group is two, and the outer two driving mechanisms 6 and the middle two driving mechanisms 6 are arranged in a staggered manner.

[0026] Specifically, the two groups of driving mechanisms 6 give pulling force or pushing force to the sealing plates 5 on both sides of the supporting plate 2, and the staggered arrangement can not affect each other.

[0027] As Figure 4As shown, the driving mechanism 6 comprises a first fixed block 601 and a second fixed block 602 fixed on the upper surface of the support plate 2, a first rotating shaft 603 rotatably connected between the first fixed block 601 and the second fixed block 602, a third fixed block 604 and a fourth fixed block 605 fixedly connected on the upper surface of the sealing plate 5, a second rotating shaft 606 rotatably connected between the third fixed block 604 and the fourth fixed block 605, a multi-stage electric telescopic rod 607 fixedly connected on the first rotating shaft 603, and the output end of the multi-stage electric telescopic rod 607 is fixedly connected with the second rotating shaft 606.

[0028] Specifically, when it is needed to open the sealing plate 5 to add raw materials into the tank body 1, the multi-stage electric telescopic rod 607 can be driven to gradually shorten, thereby giving the sealing plate 5 a pulling force, and the sealing plate 5 rotates with the L-shaped connecting block 403 and the connecting rod 402 on the limiting block 401, in the process of rotating upward, the output end of the multi-stage electric telescopic rod 607 rotates with the second rotating shaft 606, and the base of the multi-stage electric telescopic rod 607 rotates with the first rotating shaft 603, so as to adjust the angle of the multi-stage electric telescopic rod 607, and according to the opposite operation, the sealing plate 5 can be re-covered on the upper end of the tank body 1.

[0029] As shown in the drawings, Figure 1 The height of the first fixed block 601 and the second fixed block 602 is much higher than the height of the third fixed block 604 and the fourth fixed block 605.

[0030] Specifically, this is to make the multi-stage electric telescopic rod 607 have enough initial angle, and after driving the multi-stage electric telescopic rod 607, it is convenient for the sealing plate 5 to normally rotate.
