Referring to fig. 1 to 9, in one embodiment of the present invention, the driving portion 2 includes a driving motor 21, a driving shaft 22, a first driving gear 23 and a second driving gear 24, wherein the driving motor 21 is connected to the driving shaft 22, the first driving gear 23 and the second driving gear 24 are fixedly mounted on a surface of the driving shaft 22, the second driving gear 24 is located above the first driving gear 23, and a diameter of the second driving gear 24 is larger than a diameter of the first driving gear 23.
Further, the upper fixing frame 14 and the lower fixing frame 15 are respectively and fixedly installed on the upper side and the lower side of the barrel body 1, the central tube 31 and the central rod 41 are both installed on the surface of the upper fixing frame 14, the adjusting part 6 is installed on the surface of the lower fixing frame 15, the first transmission gear 32 and the second transmission gear 42 are respectively and fixedly installed on the surfaces of the central tube 31 and the central rod 41, the diameter of the first transmission gear 32 is larger than that of the second transmission gear 42, the first driving gear 23 is in transmission connection with the first transmission gear 32, and the second driving gear 24 is in transmission connection with the second transmission gear 42.
In the embodiment of the present invention, since the first driving gear 23 and the second driving gear 24 are connected to the same driving shaft 22, the linear speed of the second driving gear 24 is greater than that of the first driving gear 23, and according to the gear transmission principle, the linear speed of the second driving gear 42 is greater than that of the first driving gear 32, and since the diameter of the first driving gear 32 is greater than that of the second driving gear 42, the rotation speed of the central tube 31 is less than that of the central rod 41, so that the rotation speed of the screen shell 33 is less than that of the scattering portion 43 and the stirring rod 44, and because in practical application, a larger rotation speed is required to stir the materials in a short time, and the screen shell 33 only needs to keep rotating at a certain speed, so that the materials are uniformly distributed in the area of the scattering portion 43 and the stirring rod 44 below, if the speed of the screen shell 33 is higher, the generated larger centrifugal force drives the surface of the screen shell 33 to move towards the edge of the screen shell 33, and the problem of stacking the materials is instead generated.
Referring to fig. 10, in an embodiment of the invention, the adjusting portion 6 includes a control power source 61, a conductive seat 62 and an electromagnet 63, wherein the control power source 61 and the conductive seat 62 are mounted on the surface of the lower fixing frame 15, the electromagnet 63 is disposed on the lower surface of the conductive seat 62, the control power source 61 is electrically connected with the conductive seat 62, and the electromagnet 63 after being energized magnetically attracts the magnet piece 531.
In the embodiment of the present invention, when the control power source 61 energizes the conductive base 62 and the electromagnet 63, the magnetic attraction between the electromagnet 63 and the magnet piece 531 enables the fourth transmission gear 53 to be separated from the second engaging tooth 461, at this time, the center rod 41 does not drive the L-shaped plate 52 to move when rotating, when the L-shaped plate 52 needs to be driven to move, the control power source 61 de-energizes the conductive base 62 and the electromagnet 63, the electromagnet 63 after de-energizing loses the magnetic attraction to the magnet piece 531, at this time, the fourth transmission gear 53 falls back to the surface of the limiting piece 54 under the action of gravity, at this time, the fourth transmission gear 53 is engaged with the second engaging tooth 461.
Working principle: first, the driving motor 21 drives the first driving gear 23 and the second driving gear 24 to rotate through the driving shaft 22, the rotating first driving gear 23 and the second driving gear 24 drive the central tube 31 and the central rod 41 to rotate through the first transmission gear 32 and the second transmission gear 42, respectively, the rotating central tube 31 drives the sieve shell 33 to rotate, the rotating central rod 41 drives the scattering part 43, the stirring rod 44 and the chain stirring blade 45 to rotate, and the rotating scattering part 43 drives the rigid stirring blade 434 to rotate around the transverse rotating rod 432 by using the transmission connection between the third transmission gear 433 and the first meshing teeth 131.
Then, the tailing fine powder is added into the barrel body 1 from the feed port 11 through a conveying machine, but the tailing fine powder in the application does not directly fall to the bottom of the barrel body 1, but directly falls into the screen material shell 33 rotating downwards, and the rotating screen material shell 33 can drive the tailing fine powder to rotate together;
then, the pump body 71 sprays the activator into the screen shell 33 which rotates downwards through the feed pipe 72, the annular connecting pipe 74 and the spray pipe 73, so that the tailing micro powder in the screen shell 33 can continuously rotate and shake up and down, and can be uniformly contacted with the activator, and the surface of the screen shell 33 is inclined from the circumferential direction to the central position, so that the tailing micro powder and the activator can move towards the middle position along the surface of the screen shell 33, and in the moving process, the activator and the tailing micro powder with smaller particle size can uniformly fall downwards through the screen shell 33;
next, the electric telescopic rod 35 drives the sieve material shell 33 to move up and down according to a certain frequency, so that part of tailing micro powder can be prevented from adhering to the surface of the sieve material shell 33, and the falling speed of the activator and the tailing micro powder through the sieve material shell 33 is also improved;
then, when the tailing fine powder mixed with the activator falling from the screen housing 33 passes through the moving scattering part 43, the rigid stirring blades 434 rotating around two different axes can stir and scatter the activator and the tailing fine powder at once, so that the activator and the tailing fine powder can be more uniformly distributed in the barrel body 1, and as the activator and the tailing fine powder in the barrel body 1 are continuously increased, the rotating stirring rod 44 and the chain stirring blades 45 can further stir the mixed activator and tailing fine powder, so that the activation effect of the tailing fine powder is improved to the greatest extent;
finally, the discharge opening 12 is opened, the activated tailing micro powder in the bucket body 1 is discharged outwards through the discharge opening 12, when the activated tailing micro powder is almost discharged, the electromagnet 63 is powered off through the control power supply 61, the electromagnet 63 after power failure loses the magnetic attraction to the magnet piece 531, the fourth transmission gear 53 falls to the surface of the limiting piece 54 under the action of gravity, at this time, the fourth transmission gear 53 is in transmission connection with the second meshing teeth 461 on the inner wall of the rotary shell 46, the rotary center rod 41 drives the second movable sleeve 51 and the L-shaped plate 52 to rotate through the rotary shell 46, the second meshing teeth 461 and the fourth transmission gear 53, and the rotary L-shaped plate 52 not only can clean the tailing micro powder adhered to the inner wall of the bucket body 1, but also can clean and push the cleaned tailing micro powder into the discharge opening 12, so that the activated tailing micro powder is prevented from remaining in the bucket body 1 to the maximum extent, and the utilization of the activated tailing micro powder is maximized.
Summarizing: compared with the traditional micro powder activation stirring equipment, the activation effect is greatly improved, and the utilization rate of the activated tailing micro powder is greatly improved.
It should be noted that the technical scheme in the application is not only suitable for the field of activation of tailing micropowder, but also suitable for the field of mixing and stirring of other materials.
