[0002] The raw materials for electrodes in sodium-ion battery processing usually include sodium nickel oxide, sodium manganese oxide, and sodium iron oxide, and a stirring device is required to disperse and mix the electrode raw materials to ensure that all raw materials are evenly distributed, which is crucial for the subsequent production and performance of the electrodes. With continuous high-speed stirring, the electrode raw materials tend to generate a lot of heat.

[0003] At present, the patent with announcement number CN218339488U discloses a sodium ion battery processing electrode raw material stirring equipment, including three stirring boxes and a driving mechanism, the three stirring boxes are connected by a through pipe, each stirring box is provided with a stirring rod, and the driving mechanism drives each stirring rod to rotate synchronously at different speeds. The electrode slurry inside each stirring box is stirred in order, the rotation speed of the stirring rod in the second stirring box is its normal speed, and the other two are excess speed and too slow speed. In the third stirring box, the stirring is completed, and the cooling liquid in the sleeve and the slow rotating stirring rod drive the internal electrode slurry to move, so that the heat in the electrode slurry is transferred to achieve the purpose of cooling, thereby slowing down the stirring speed in turn, thereby improving the stirring quality of the electrode slurry, and finally, through stirring and the contact physical cooling of the cooling liquid of the sleeve, the electrode slurry in the lowermost stirring box is cooled, saving the subsequent heat dissipation process, thereby improving the processing efficiency of the electrode slurry.

[0004] However, the following problems still exist in the use of current electrode raw material mixing equipment:

[0005] When in use, the above-mentioned device only cools the mixer box by water cooling, and the cooling effect is not good. The two mixer boxes at the upper end cannot be cooled, which causes the temperature of the raw materials in the mixer box at the lower end to be too high due to accumulation and temperature rise, affecting the water cooling effect. When the raw materials are unloaded, because the device is placed horizontally, the raw materials on the left side of the mixer box are prone to incomplete unloading. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model provides an electrode raw material stirring device for sodium ion battery processing. Fan blades are added on the right side of each stirring machine box to blow heat to the outside of the box to dissipate heat, thereby avoiding the accumulation and heating of raw materials. The device is lifted and tilted to ensure that all raw materials are unloaded.

[0009] Furthermore, the rear side of the cooling device is configured as an arc structure that fits tightly with the mixer box, and circulating water pipes are provided on the upper end and left side of the cooling device. Through the above structure, it is easy to ensure that the cooling device and the mixer box are fully fitted, thereby ensuring the cooling effect of the raw materials in the mixer box.

[0010] Furthermore, the stirring assembly includes a motor and a rotating shaft, and the motor is arranged on the left side of the first support plate, the rotating shaft is connected to the output end of the motor, and the rotating shaft forms a rotating mechanism with the first support plate through a bearing installed on the first support plate, the rotating shaft is rotatably connected to the second support plate, and the rotating shaft is rotatably connected to the stirring box.

Through the above structure, the left side of the frame can be tilted through the operation of the electric telescopic rod, so that the raw materials can be fully unloaded.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The electrode raw material stirring device for sodium ion battery processing can drive the heat dissipation fan blades to dissipate heat from the raw materials while stirring and mixing the raw materials through the rotation of the rotating shaft, thereby avoiding heat accumulation in the raw materials.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-Figure 5 The utility model provides a technical solution: an electrode raw material mixing device for sodium ion battery processing, comprising a frame 1, a first support plate 2 is arranged on the left side of the upper surface of the frame 1, and a second support plate 3 is arranged on the right side of the upper surface of the frame 1; a fixed plate 4 is fixedly arranged on the upper end of the frame 1, and the fixed plate 4 is fixedly installed at the lower end of the mixing machine box 5, a material guide pipe 12 is penetrated on the right side of the mixing machine box 5, a cooling device 7 is fixedly arranged on the upper surface of the frame 1, and a mixing component 8 is arranged on the left side of the first support plate 2; there are three mixing machine boxes 5, which are divided into an upper mixing machine box 5, a middle mixing machine box 5 and a lower mixing machine box 5 according to their positions, a feeding port 6 is penetrated on the upper left end of the upper mixing machine box 5, and a feeding port 6 is penetrated on the lower end of the lower mixing machine box 5. The position mixer box 5 is tightly fitted with the cooling device 7; the stirring component 8 includes a motor 801 and a rotating shaft 802, and the motor 801 is arranged on the left side of the first support plate 2, the rotating shaft 802 is connected to the output end of the motor 801, and the rotating shaft 802 forms a rotating mechanism with the first support plate 2 through a bearing installed on the first support plate 2, the rotating shaft 802 is rotatably connected with the second support plate 3, and the rotating shaft 802 is rotatably connected with the mixer box 5; the stirring component 8 also includes stirring blades 803 and a pulley group 804, the stirring blades 803 are equidistantly arranged on the rotating shaft 802, and the pulley group 804 is fixedly installed on the left side of the rotating shaft 802, and the heat dissipation fan blades 9 are installed on the right side of the rotating shaft 802.

[0023] When the electrode raw materials need to be stirred, the raw materials are added to the upper stirring box 5 through the feeding port 6, and then the motor 801 starts to work. Because the output end of the motor 801 is connected to the rotating shaft 802, and the rotating shaft 802 is equipped with a pulley group 804, the three rotating shafts 802 all start to rotate. Because the rotating shaft 802 is equipped with a stirring blade 803, the stirring blade 803 can be used to stir the raw materials (there are two pulley groups 804, and the pulley group 804 is composed of a rotating wheel and a belt, And the diameter of the wheel at the lower end of a pulley group 804 is larger than the diameter of the wheel at the upper end. At this time, through the rotation of the pulley group 804, the rotation speed of the three rotating shafts 802 increases from bottom to top, that is, the stirring speed in the mixer box 5 at the upper end is the fastest, the stirring speed in the middle mixer box 5 is medium, and the stirring speed in the lower mixer box 5 is the lowest, thereby achieving the purpose of graded stirring). The raw materials after each stage of stirring fall into the mixer box 5 at the lower end through the material guide pipe 12, and then are uniformly collected and stored through the collection box 10.

[0024] A heat dissipation fan blade 9 is fixedly provided on the stirring component 8, a collecting box 10 is fitted on the upper surface of the frame 1, and the collecting box 10 is connected to the threaded holes opened on the second support plate 3 by screws, and a tilting component 11 is provided at the lower end of the frame 1; the rear side surface of the cooling device 7 is arranged as an arc structure that fits tightly with the stirring machine box 5, and a circulating water pipe is arranged on the upper end and the left side of the cooling device 7; the tilting component 11 includes a receiving plate 111, a connecting ball 112 and an electric telescopic rod 113, and the receiving plate 111 is fixedly installed on the lower surface of the left side of the frame 1, and the connecting ball 112 is rollingly connected with the receiving plate 111 through a spherical groove opened at the lower end of the receiving plate 111, and the electric telescopic rod 113 is fixedly installed at the lower end of the connecting ball 112.

[0025] Because the rotating shaft 802 is equipped with heat dissipation blades 9, as the rotating shaft 802 rotates, the heat dissipation blades 9 also start to rotate, that is, the rotation of the heat dissipation blades 9 can realize air cooling and heat dissipation of the three mixer boxes 5, and then the mixer box 5 at the lower end is fitted with water cooling and heat dissipation through the cooling device 7 (the mixer box 5 and the cooling device 7 are set to stainless steel, aluminum and other materials with good thermal conductivity). At this time, the cooling device 7 starts to water-cool the raw materials (the cooling device 7 is connected to the external heat dissipation fins through a circulating water pipe, which can continuously ensure that there is cold water in the cooling device 7 ), and when the raw materials are discharged through the material guide tube 12, the electric telescopic rod 113 starts to work, because the upper end of the electric telescopic rod 113 is provided with a connecting ball 112, at this time the connecting ball 112 starts to roll in the spherical groove opened at the lower end of the receiving plate 111, that is, the left side of the frame 1 is slightly lifted (the surface of the pad set at the lower end of the electric telescopic rod 113 is smooth), when the left side of the frame 1 is slightly lifted, the electric telescopic rod 113 can move slightly to the right, and the mixer box 5 is in a tilted state at this time, which can effectively ensure that the raw materials in the mixer box 5 are fully discharged.
