Detailed Implementation

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0022] like Figures 1-4 As shown, a vacuum rotary oven includes a mounting base 1, a vacuum rotary oven 4, a drive mechanism 2 connected to the mounting base 1, a transmission mechanism 3 connected to the output end of the drive mechanism 2, a hollow rotary shaft 5 connected to the transmission mechanism 3, a conductive slip ring 6 sleeved on the outer wall of the hollow rotary shaft 5, a first support 7 connecting the mounting base 1 and the vacuum rotary oven 4, and a second support 8 connecting the mounting base 1 and the hollow rotary shaft 5. One end of the hollow rotary shaft 5 is connected to the vacuum rotary oven 4.

[0023] The vacuum rotary oven has a first support base 7 and a second support base 8 mounted on the mounting base 1. These supports support the vacuum rotary oven 4 and the hollow rotating shaft 5, allowing them to rotate under the drive of the drive mechanism 2 and the transmission mechanism 3. This avoids uneven heating caused by static baking, which leads to low recovery efficiency. Furthermore, the vacuum rotary oven 4 employs a vacuum design, allowing the electrolyte to evaporate even at lower baking temperatures, preventing excessively high baking temperatures from causing smoke on the cathode and anode films and affecting electrolyte recovery. The conductive slip ring 6 helps prevent the wiring harness connected to the vacuum rotary oven 4 from rotating and tangling.

[0024] Further, the vacuum rotary oven further comprises a rotary joint 9 connected to the other end of the hollow rotary shaft 5, and a vacuum pump connecting pipe 10 connected to the rotary joint 9, and the vacuum rotary oven 4, the hollow rotary shaft 5, the rotary joint 9 and the vacuum pump connecting pipe 10 are sequentially communicated. The vacuum pump connecting pipe 10 is used to connect the vacuum pump and the cold trap part. In use, the vacuum pump is used to extract the air in the vacuum rotary oven 4 through the vacuum rotary oven 4, the hollow rotary shaft 5, the rotary joint 9 and the vacuum pump connecting pipe 10 in sequence; and the electrolyte volatilized during the baking process is also transported through the vacuum rotary oven 4, the hollow rotary shaft 5, the rotary joint 9 and the vacuum pump connecting pipe 10 in sequence. Further, a three-way pipe 11 is connected between the rotary joint 9 and the vacuum pump connecting pipe 10, and a pressure gauge 12 is connected to the third end of the three-way pipe 11, so as to observe the pressure value between the rotary joint 9 and the vacuum pump connecting pipe 10 in real time.

[0025] Further, the vacuum rotary oven 4 comprises a box body 41, a heating bracket 42 connected to the inner side wall of the box body 41, an electric heating assembly 43 connected to the heating bracket 42, and a thermal insulation interlayer 44 sleeved on the outer wall of the box body 41, and one end of the hollow rotary shaft 5 is communicated with the box body 41. The electric heating assembly 43 heats the box body 41, so that the temperature in the box body 41 rises, and under the thermal insulation effect of the thermal insulation interlayer 44, the heat dissipation of the box body 41 is avoided to be too fast, and the energy consumption is further reduced.

[0026] Further, the electric heating assembly 43 comprises a plurality of heating pipes connected to the heating bracket 42 and uniformly distributed along the heating bracket 42, and the heating pipes are electrically connected with the conductive slip ring 6; the plurality of heating pipes are uniformly distributed, which is beneficial to the uniform heating of the vacuum rotary oven 4 during rotation. In the embodiment, the number of the heating pipes is 6 groups.

[0027] Further, the vacuum rotary oven 4 further comprises an explosion-proof pipe 45 communicated with the inner side wall of the box body 41, an explosion-proof sheet 46 connected to the explosion-proof pipe 45, and a plurality of turbulence plates 47 connected to the inner side wall of the box body 41 and uniformly distributed along the box body 41 in a ring shape, and the turbulence plates 47 are provided with a plurality of turbulence through holes 13. In the process of baking and disassembling the battery, the explosion causes the pressure in the box body 41 to rise sharply, and the explosion-proof sheet 46 can be used for pressure relief treatment to prevent the vacuum rotary oven 4 from being damaged by explosion. The turbulence plates 47 are beneficial to the full dispersion of the baking objects during rotation, and are beneficial to the uniform heating.

[0028] Further, the vacuum rotary oven 4 further comprises a temperature sensor 48 inserted into the inner side wall of the box body 41 and electrically connected with the conductive slip ring 6, and the temperature sensor 48 is used for sensing the temperature in the box body 41. The temperature sensor 48 can be selected from a platinum resistance PT100.

[0029] Further, the box 41 is fixedly connected with an outlet filter screen 15 at a communicating end of the hollow rotating shaft 5; and the other end of the box 41 is hingedly connected with a sealing cover door 16. The outlet filter screen 15 can effectively prevent the debris generated in the baking process from entering the vacuum pump and the cold trap through the hollow rotating shaft 5.

[0030] Further, the driving mechanism 2 comprises a speed reducer motor, the transmission mechanism 3 comprises a first synchronous wheel 31 connected with the output end of the speed reducer motor, a second synchronous wheel 32 connected with the hollow rotating shaft 5, and a synchronous belt 33 connecting the first synchronous wheel 31 and the second synchronous wheel 32. The first synchronous wheel 31 is driven to rotate by the speed reducer motor, and the first synchronous wheel 31 drives the second synchronous wheel 32 and the hollow rotating shaft 5 to rotate through the synchronous belt 33, and the hollow rotating shaft 5 drives the vacuum rotary oven 4 to rotate.

[0031] Further, the first support base 7 comprises two screw adjusting pull rods 71 symmetrically arranged on both sides of the mounting base 1, and rollers 72 rotatably connected with the top ends of the screw adjusting pull rods 71, and the outer side wall of the vacuum rotary oven 4 is provided with an annular sliding rail 14 which is in sliding fit with the rollers 72. The two screw adjusting pull rods 71 symmetrically arranged on both sides of the mounting base 1 are in sliding fit with the annular sliding rail 14 through the rollers 72, which not only supports the vacuum rotary oven 4, but also ensures that the vacuum rotary oven 4 can rotate. Moreover, the two screw adjusting pull rods 71 can adjust the angular height thereof to adjust the concentricity of the vacuum rotary oven 4 and the hollow rotating shaft 5 during rotation, so as to avoid that the concentricity deviation is too large to cause the vacuum rotary oven 4 to deviate and produce abnormal sound during rotation and affect the rotation of the vacuum rotary oven 4.

[0032] Further, the second support base 8 comprises a support rod 81 connected with the mounting base 1, and a bearing seat 82 connected with the top of the support rod 81, and the inner ring of the bearing seat 82 is sleeved with the hollow rotating shaft 5, so as to support the hollow rotating shaft 5 and ensure that the hollow rotating shaft 5 can rotate.

[0033] The above embodiment is the preferred implementation scheme of the present application, in addition to this, the present application can be realized in other ways, any obvious replacement without departing from the concept of the present application is within the protection scope of the present application.
