Background

With the progress and development of society, products driven by new energy such as batteries are more and more popular, small products have electronic products, large vehicles (electric vehicles) and the like, driving batteries adopted by the products are basically lithium batteries (or other batteries capable of being rapidly and repeatedly charged), and the preparation of lithium battery slurry (new energy materials) relates to the stirring and mixing of various materials.

Therefore, an affiliated subsidiary company of my department develops a stirring device capable of improving the stirring uniformity of new energy materials, and particularly discloses an industrial stirring device mainly used for mixing lithium battery materials, which is disclosed in 2018, 5, 29.s, in Chinese patent publication No. CN108079870A, and comprises a rack, a stirring mechanism, a dispersing mechanism, a supporting assembly, a stirring driving device and a dispersing driving device, wherein the supporting assembly is in rotating fit with the rack, the stirring mechanism and the dispersing mechanism are respectively and rotatably arranged on the supporting assembly, a synchronous gear is arranged on the supporting assembly, a fixed gear is arranged on the rack, and the synchronous gear is meshed with the fixed gear and rotates around the fixed gear; rotation and revolution can be realized simultaneously to this kind of stirring mechanism's among the industrial agitated vessel stirring rake and dispersion axis of dispersion mechanism, the stirring rake is equipped with three, is equipped with the stirring rake connecting axle on each stirring rake respectively, and the stirring rake connecting axle distributes outside the rotation center of protection casing with the form of non-equipartition, both can realize the center that the stirring region covered the storage bucket, also can make the space of equidimension not vacate below the lower box cover of protection casing. The number of the dispersing shafts is equal to that of the connecting shafts of the stirring paddles, the dispersing shafts are arranged in the space vacated by the lower box cover, wherein two dispersing disks with upper and lower small diameters are arranged on the two dispersing shafts, and two dispersing disks with upper and lower large diameters are arranged on the other dispersing shaft, so that a larger area of dispersed materials is formed. Therefore, the stirring paddles and the dispersing shafts of the stirring equipment pass through more areas, so that the mixing effect is improved.

However, the requirement of the current new energy material stirring process is extremely high, and the equipment is another core technology of the equipment to be brought into full play. Therefore, the following core work is to find out some unobtrusive defects in the prior art and overcome the defects, so as to avoid material scrap caused by equipment problems or potential safety hazards of the materials in use.

As shown in fig. 12 and 13, the above-mentioned stirring apparatus has been developed so far, and after being tested in various stirring manners, it is finally found that the following disadvantages exist:

1. during high-speed operation, lubricating grease splashes to the charging basket at the position of the stirring driving gear 93, the specific reason is that a region enclosed by the fixed sleeve 910 (evacuation sleeve) and the charging basket 913 is in a negative pressure state during stirring, the diameter of the stirring driving gear 93 is smaller, the outer ring tooth surface (larger diameter) of the ring gear 94 is meshed with the top of the protective cover 99 in the fixed sleeve and the stirring driving gear 93, therefore, the stirring driving gear 93 and the ring gear 94 are in transmission, and belong to obvious speed reduction transmission, the stirring driving gear 93 is driven by the stirring driving motor 91 to rotate at a high speed, so that lubricating grease on the gear splashes, the splashed lubricating grease enters the space between the inner wall of the fixed sleeve 910 and the outer wall of the protective sleeve 99 through the gap I between the protective sleeve 99 and the cross beam 92 of the rack, and then enters the material barrel 913, so that the material is polluted, and even the stirring quality is influenced.

2. The problem of hollow shaft bearing is that the protective cover 99 and the stirring paddles 916, the dispersion shaft 912, the gear assembly and the like on the protective cover 99 are supported by the hollow shaft 96, the protective cover 99 is in rotating fit with the hollow shaft 96, the hollow shaft 96 is rotatably arranged on the cross beam 92 and is in transmission connection with the dispersion driving motor 98, and meanwhile, the hollow shaft 96 is used for providing power for the dispersion shaft 912, but the existing hollow shaft 96 is connected with the cross beam 92 through the ball bearing 97, so that the axial stress is weak, severe abrasion is easy to occur during high-speed operation, and meanwhile, the risk of falling is also brought.

3. The root of the connection between the dispersion shaft 912 and the protection cover 99 has a step 911, and when the dispersion shaft 912 rotates at a high speed, the step 911 is easily broken due to stress concentration.

4. The stirring rake 916 has a large resistance when stirring materials, and the stirring rake connecting shaft 95 at the upper end of the stirring rake 916 is supported by only one bearing 917 with the bottom of the protective cover 99, so that the supporting force is insufficient.

5. The charging barrel 913 is lifted through a bracket 914 in transmission connection with the servo electric cylinder 915, and the servo electric cylinder 915 is controlled through a stroke switch, stops at a fixed position after reaching a stroke, but does not continuously provide a thrust force upwards, so that the charging barrel 913 cannot keep a pressing state with the fixing sleeve 910 for a long time in a lifting state, and the sealing performance is reduced; moreover, this phenomenon is also related to the accuracy of the servo electric cylinder 915 and the wear of parts after a long period of use.

In addition, because the rotating acting force of the hollow shaft is directly transmitted to the center of the protective cover, and the stirring driving motor can directly control the rotating speed of the hollow shaft to meet the requirement of the rotating speed of the protective cover, the stirring driving motor can be a low-speed motor, and the cost is lower.

Because the resistance that the stirring rake bore is great among the stirring process, for the lower extreme support dynamics that has improved the stirring rake connecting axle, set up two ball bearing. In addition, the ball bearing which generates less heat during rotation is used for supporting, considering that the operation of the bearing generates heat which is transferred to the new energy material to be stirred through the stirring paddle and causes certain influence.

As a further scheme, a protective cover is arranged on the beam corresponding to the upper ends of the hollow shaft and the central shaft, and the upper ends of the hollow shaft and the central shaft are respectively connected with the protective cover through bearings; the upper end of the central shaft is in transmission connection with the dispersion driving motor through a first belt transmission mechanism, the upper end of the hollow shaft is in transmission connection with the stirring driving motor through a second belt transmission mechanism, and the dispersion driving motor and the stirring driving motor are distributed on the cross beam in a left-right mode. The two motors are distributed left and right, so that the whole machine is more stable. In addition, the diameter of the stirring driving gear in the prior art is smaller, so the outer diameter of a belt pulley connected with the stirring driving gear is also smaller, the contact area of the belt pulley and a belt is small, and the problem of transmission loss is easy to occur; the hollow shaft has a larger outer diameter, so that the first driven pulley connected to the hollow shaft has a larger outer diameter, so that a larger contact area with the belt is provided and the transmission of force is more ensured.
