Example one
Fig. 1 and 2 show schematic structural diagrams of a lithium battery raw material slurry mixing device provided in a preferred embodiment of the present application, and for convenience of description, only parts related to the embodiment are shown, which are detailed as follows:
the utility model provides a lithium battery raw materials mixing of pulp device, includes agitator 12, 12 tops of agitator are equipped with feed inlet 11, and the bottom is equipped with feed opening 10, be equipped with transmission shaft 2 in the agitator 12, the transmission shaft is through setting up in the drive motor 1 drive at top. The bottom of the transmission shaft 2 is fixed with a stirring wheel 7 through a transmission shaft internal thread 21 and a stirring wheel external thread 71, the stirring wheel 7 is provided with a stirring wheel blade 9, the stirring wheel 7 is provided with a stirring wheel hole 8 which is axially penetrated, and the stirring wheel hole 8 comprises a plurality of radially distributed holes. The middle part of the transmission shaft 2 is provided with a stirring blade 4, and the stirring barrel 12 is fixedly provided with a spacing ring 6 between the stirring blade 4 and the stirring wheel 7.
In one embodiment, the stirring vanes 9 are uniformly arranged around the bottom edge of the stirring wheel 7, and a gap for material to flow is arranged between the stirring vanes 9 and the bottom wall of the stirring barrel 12. The clearance is too small, the material is not easy to flow and is easy to wear; too large gap can not form effective negative pressure, and the stirring effect is not good. In this embodiment, the gap between the lowest point of the stirring vane 9 and the inner bottom wall of the stirring barrel 12 is 10-30 cm.
In one embodiment, the stirring blade 9 comprises a horizontal part 92 and a vertical part 91 arranged below the horizontal part 92, one end of the horizontal part 92 is fixed with the bottom edge of the stirring wheel 7, the other end extends to the outer side of the stirring wheel 7, and the vertical part 91 is fixedly connected with one end of the horizontal part 92 extending to the outer side of the stirring wheel 7. The horizontal portion 92 and the vertical portion 91 of the stirring vane 9 are formed like "7". The horizontal part 92 and the vertical part 91 are connected together to facilitate processing, welding is not needed, the strength is high, abrasion is not easy to occur, the contact area between the wheel blade and materials can be increased in a 7-shaped mode, the materials are scattered as far as possible in the stirring process, and negative pressure is generated inside the wheel blade. And the design can reduce the integral volume occupancy of the stirring wheel and improve the treatment capacity.
In one embodiment, the stirring blades 4 are uniformly arranged around the transmission shaft 2, the stirring blades 4 are arranged in a downward inclined mode, and the extension length of the stirring blades 4 in the horizontal direction is smaller than the radius of the isolation ring 6.
In one embodiment, the outer wall of the isolating ring 6 is fixedly connected with the inner part of the stirring barrel 12 through an isolating ring bracket.
In one embodiment, the top surface of the stirring wheel 7 is a cambered surface structure with the center height higher than the edge height and protruding downwards. This cambered surface design can reduce the friction of top surface and material, promotes the flow of material, reduces the volume of stirring wheel simultaneously, improves the capacity utilization ratio.
In one embodiment, the distance between the top of the isolation ring 6 and the lowest point of the stirring blade 4 is 10-50 cm, and the stirring blade 4 can stir materials outside the isolation ring and perform primary mixing, and simultaneously bring the materials into the ring from the outside to promote the movement and dispersion of the materials. In the vertical direction, the distance between the lowest point of the stirring blade 4 and the highest point of the isolating ring 6 can be 10-50 cm, and enough channels are reserved, so that materials can smoothly enter the ring under the action of the stirring blade 4 or the action of upward extrusion of the materials at the bottom, and cannot enter the isolating ring when the stirring blade 4 rotates at a high speed.
In one embodiment, the distance between the bottom of the isolation ring 6 and the lowest point of the top surface of the stirring wheel 7 is 5-30 cm in the vertical direction. The inner diameter of the isolating ring 6 is larger than the diameter of the stirring wheel 7, and the difference value of the diameters of the isolating ring and the stirring wheel is 5-20 cm. The distance is that a certain gap is kept between the isolating ring and the stirring wheel, so that the materials can flow smoothly, but the distance is too large, only a small part of the materials enter the bottom through the stirring wheel hole 8 to be mixed, and an ideal stirring effect cannot be achieved; the space is too small, the material flows slowly, and the stirring efficiency is low.
The working process of the device is as follows:
when the equipment works, the transmission motor 1 drives the transmission shaft 2 to rotate at a high speed, and the stirring blades 4 and the stirring wheel 7 move together to stir internal materials. The material is poured into the equipment from the feed opening 10, part of the material enters the inside of the isolating ring 6, and part of the material enters the outside of the isolating ring 6. The material entering the inside of the isolating ring is firstly dispersed under the stirring action of the stirring blades 4, or is thrown into the isolating ring, or is thrown out of the isolating ring. When the stirring vanes 9 rotate at high speed, the pressure between the stirring vanes 9 and the bottom of the equipment is small, and the materials entering the isolating ring can rapidly pass through the stirring wheel holes 8 under the action of the stirring vanes 4, enter the space between the stirring vanes 9 and the bottom of the equipment, are further mixed, and are then thrown out of the isolating ring 6. Under the extrusion action of the subsequent materials, the materials move upwards and enter the isolating ring 6 again through the stirring blades 4, and the process is circulated until the materials are uniformly mixed.
The above-mentioned embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the spirit and scope of the embodiments of the present application and are intended to be included within the scope of the present application.
