[0026] Example:
[0027] As shown in the figure, the technical solution provided by the present invention is a one-axis multi-cylinder multi-dimensional ball hammer type micro-nano high-energy ball mill, a frame 36 and an eccentric shaft drive device, an eccentric shaft support device and a rotary disc crushing device installed in the frame, so The eccentric shaft drive device is composed of a frequency converter control motor 1, a pulley 2, an eccentric shaft 3, a bearing seat 4, 5 and a number of bearings 6, 7. One end of the eccentric shaft 3 is installed on the pulley 2, and the other end is connected to the pulley 2. The bearings 6 and 7 installed on the bearing seat are fixedly connected. The pulley 2 is connected to the inverter control motor 1 through the transmission belt 35, and then drives the eccentric shaft 3 to move. The angle of the eccentric shaft 3 is 10-20 degrees. On the contrary, the smaller the machine is, the larger the angle is, that is, when the machine is larger, the distance between the edge of the disc 20 and the axis of the eccentric shaft 3 will be larger, and the relative eccentricity angle will be smaller. The closer the distance between the edge and the eccentricity, the smaller the movement of the cylindrical grinding jar, and the larger the angle of the eccentric shaft 3.
[0028] The eccentric shaft support device includes one or more pulleys 8, 10, 11, a linkage shaft 9, a support shaft 12, a support seat 13, and bearing seats 14, 15. The bearing seats 14, 15 are installed on the two sides of the support seat 13. At the end, the support base 13 is fixed on the support shaft 12, one end of the support shaft 12 is installed with the pulley 11, and the other end is connected with an oblique connecting plate 16, which is fixed by the eccentric shaft top cover 17 and connected with the eccentric shaft 3, The inclined connecting plate is fixed by screws 18 and 19. Both ends of the linkage shaft 9 are equipped with pulleys 8 and 10. The pulley 8 at one end of the linkage shaft is connected with the above-mentioned frequency converter control motor 1 through the transmission belt 35. The drive belt 35 is connected with the pulley 11 installed on the above-mentioned support shaft 12. The eccentric shaft support system is also the same frequency converter to control the motor 1. The belt pulley 8 at the front end of the linkage shaft 9 is driven by the conveyor belt 35 and drives the pulley 10 at the rear end of the linkage shaft. Then the pulley 11 in the front section of the support shaft is driven, the support shaft 12 is movably matched with the bearing seats 14 and 15, and the other end of the support shaft 12 is fixed with the inclined connecting plate 16 and the inclined connecting plate at the same time with the eccentric shaft 3, so as to achieve synchronous rotation with the eccentric shaft. The eccentric shaft 3 is supported. Since the supporting shaft 12 can bear 40% of the torsion force of the eccentric shaft, the wearing parts are turned to the slanted connecting plate 16 or the bearings 14 and 15 on the support base 13, so that the eccentric shaft 3 is protected and the equipment runs relatively Stable and long life cycle.
[0029]The turntable crushing device includes a disc 20 , a turntable bearing seat 21 and more than one cylindrical grinding pot 25 , the turntable bearing seat 21 is fixed at the center of the disc 20 , and the turntable bearing seat 21 is fixed with the above-mentioned eccentric shaft 3 . The cylindrical grinding pots 25 are evenly distributed and installed on the disc 20. The number of cylindrical grinding pots can be several or dozens or even dozens. The outer end of the disc 20 is also installed with a first joint bearing 31. , the lower end of the first joint bearing 31 is provided with a tension spring 33 and a universal joint 32, a second joint bearing 34 is arranged between the tension spring 33 and the frame 1, and one end of the tension spring 33 passes through the universal joint 32 It is connected with the first joint bearing 31, and the other end is connected with the second joint bearing 34; the second joint bearing 34 is fixed on the frame, and the disk 20 adopts a vertical disk or a horizontal disk, and the present invention adopts a vertical disk A disc, on which there are several, dozens or dozens of horizontal cylindrical grinding jars arranged radioactively. One rotation of the eccentric shaft can make the cylindrical grinding jar move in multiple different directions. The cylindrical grinding jar swings up and down, left and right, and back and forth once, and the balls impact once at a high speed, which can be regarded as "rotation". The crushed items are plants, minerals, and non-metals. The object is metal and the eccentric shaft rotates 600-800 times per minute, and the "revolution" of the disc 20 is controlled by a soft pulling combination. The soft pulling combination is a tension spring 33 connected by the first joint bearing 31 on the edge of the disc and the universal joint 32, and the other end of the tension spring 33 is also connected with a second joint bearing 34 and the universal joint and fixed on the machine. On the shelf, no matter how the disc swings, the tension spring can pull the disc, so that it cannot "revolve", because once the "revolution" runs, it will offset the rotation of the roulette and the grinding pot, making the multi-dimensional swing and the ball hammer. Action disappears.
[0030] The present invention is further described below:
[0031] like figure 1 As shown, the angle of the eccentric shaft 3 designed by the present invention is 10-20 degrees, which is rotated with the help of the eccentric shaft driving device and the eccentric shaft supporting device, and drives a vertical disc to rotate, and the disc is equipped with a plurality of horizontal The cylindrical grinding jar, the eccentric shaft 3 and the supporting system are rotated to drive the cylindrical grinding jar to swing up and down, left and right, and front and back regularly to form multiple movements of high-energy ball milling.

The mill jar swings forward.
[0039] Step 2: Image 6 , Figure 10 As shown, when the eccentric shaft is deflected to the lower side, the upper part of the disc swings forward and the upper cylindrical grinding pot swings forward, while the lower part of the disc swings backward and sinks at the same time, so that the lower cylindrical grinding pot is also backward Swing, the cylindrical grinding pots on the left and right sides are tilted upward.
[0040] The third step: as image 3 , Figure 7 As shown, when the eccentric shaft turns to the right, the disc swings to the right and the right cylindrical grinding jar swings to the right, while the right cylindrical grinding jar swings backward, and the left disc moves forward The swing drives the cylindrical grinding tank to swing forward and the rear of the upper and lower cylindrical grinding tanks swings to the right.
[0041] the fourth step: Figure 4 , Figure 9 As shown, when the eccentric shaft turns to the upper side, the disc tilts upward, the upper tank body swings backward, and the lower part of the disc tilts forward, which drives the lower cylindrical grinding tank to swing forward, while the left and right cylinders swing forward. The front of the grinding jar rises and the rear swings down.
[0042] recombination figure 2 To further explain the water cooling system of the crushing chamber:
[0043] The first method is that the water cooling device adopts a four-wall sealing structure 37 for the rotary disc pulverizing device placed in the frame. A number of water shower heads 39 for spraying the cylindrical grinding tank are sequentially installed on the top, and a water tank 40 is arranged at the bottom end of the water tank, and a drain port 41 is installed on the water tank.

Connection, the downpipe 47 is installed on the frame 46, and is connected with the elastic water outlet hose, and the water outlet enters the cold circulating water tank through the downpipe 47. The successful control of the temperature is related to the thickness of the water pipe, the pressure of the water pump and the adjustment of the chiller.
[0045] The choice of two cooling methods is: spray water cooling should be used for small experimental machines, and water circulation cooling method for grinding tank interlayer should be used for production models.
[0046] Since the jar on the vertical disc in the present invention is horizontal, if it is an experimental machine, the horizontal jar can be disassembled, and the grinding jar can be placed on a laboratory bench or in a vacuum glove box to open for operation. However, on the production tank of the large model, the horizontally placed tank is welded on the disc 20. The tank cover 26 is sealed and connected to the tank through the sealing rubber ring 28 and the screw 27. Only when the tank is cleaned Only when the inner wall is opened. During the production feeding, the ball and dry material or ball and slurry are added from the feeding port 30 to the tank through the elastic plastic tube. , screw it to the bottom. When unloading, first fix the elastic plastic tube at the discharge port and then turn the sealing bolt. At this time, start the slow rotation drive for 25 rpm, and then all the balls can be discharged.
