[0020] The bidirectional vibration powder material wet granulation device provided by the application is shown in the structure diagram.

[0021] Please refer to Figures 1 to 6The application provides a bidirectional vibration powder material wet granulation device. The drawings are only used for explaining the structural principle and are not proportional to the actual product. In order to facilitate drawing, only the structures related to the application points of the application are drawn in the drawings, and the conventional structures (support 92 and hopper 91) of the granulator are only schematically drawn; the motor is a standardized product, and is not specifically drawn in the drawings. Figure 1 In the drawings, only the section lines of the tank and the drum are schematically drawn, and all the section lines are not drawn. Figure 4 In the drawings, the drum and the screen are actually not directly observed from the outside, and are indicated by dashed lines.

[0022] The bidirectional vibration powder material wet granulation device comprises a tank 1, a screen 2 and a drum 3, and further comprises an axial vibration device, the axial vibration device comprising an exciter 71, a transducer 72 and a variable amplitude rod, the output end of the variable amplitude rod being connected with one end of the drum; the other end of the drum is connected with the output shaft 84 of a motor (not shown in the drawings); the drum is eccentrically arranged, and the outer wall of the drum 3 is provided with a plurality of rolling bars 31.

[0023] Further, the output end of the variable amplitude rod is connected with one end of the drum through a connecting shaft 75. Specifically, the connecting shaft comprises a body 751 and a boss 752, and the body is provided with a notch 750; the output end of the variable amplitude rod is inserted into the notch; one end of the drum is provided with a connecting hole 301, and the boss is in interference fit with the connecting hole. That is, the connecting shaft is fixedly connected with the drum in the interference fit mode. The diameter of the output end of the variable amplitude rod is smaller than the diameter of the notch of the connecting shaft, and the output end of the variable amplitude rod can also move axially in the notch.

[0024] Further, the other end of the drum is provided with a spline hole 302 coaxially arranged with the connecting hole, and the axis of the spline hole is eccentrically arranged with the axis of the drum; the spline hole is connected with a spline shaft 82, and the spline shaft is connected with the output shaft 84 of the motor through a shaft coupling 83. An elastic washer (not observed in the drawing) is arranged in the shaft coupling, and by arranging the elastic washer, the elastic washer can not only play a role in vibration reduction between the output shaft of the motor and the spline shaft, but also can bear the axial force applied to the drum by the axial vibration device, and improve the radial vibration effect of the drum.

[0025] Further, the rolling bars 31 are equidistantly arranged in the circumferential direction of the drum 3. In normal operation, the rolling bars will collide with the screen, so as to generate radial vibration.

[0026] Optionally, the drum is a hollow structure. This arrangement not only reduces the weight and manufacturing cost of the drum, but also makes the vibration effect of the drum better.

[0027] Preferably, the amplitude-changing rod comprises a first amplitude-changing rod 73 and a second amplitude-changing rod 74 arranged in series. When the first amplitude-changing rod and the second amplitude-changing rod are arranged, the output of the amplitude-changing rod as described above refers to the output end of the second amplitude-changing rod. By arranging the first amplitude-changing rod and the second amplitude-changing rod, the amplitude of the axial amplitude change can be further improved. Specifically, the amplitude of the second amplitude-changing rod can reach 2mm-5mm.

[0028] Preferably, two tensioning wheels 22 are arranged on the screen. By arranging two tensioning wheels, the screen can be more effectively tensioned. The structure of the tensioning wheel can be diverse, which is not specifically limited here.

[0029] As can be observed from the drawings, an outer side of the connecting shaft is provided with a shaft sleeve 51; an outer side of the spline shaft is provided with a shaft sleeve 52 and a clasp 53; and the bottom of the material tank is further provided with a discharge port 19.

[0030] As can be observed from the drawings, Figure 1 and Figure 5 It can be known that the connecting hole of the drum is coaxially arranged with the output end of the second amplitude-changing rod, and the spline hole of the drum, the spline shaft and the output shaft of the motor are coaxially arranged. The eccentric distance Δ1 between the axis 700 of the connecting hole of the drum and the axis 300 of the drum is 2mm-5mm. The eccentric distance Δ2 between the axis 800 of the spline hole of the drum and the axis 300 of the drum is 2mm-5mm.

[0031] In order to facilitate understanding, the working principle of the bidirectional vibration powder material wet granulation device is briefly described as follows.

[0032] When working, the excitation frequency generated by the high-frequency exciter is 30K-50KHz, which is converted into mechanical vibration by the transducer, and the amplitude is amplified to 2mm-5mm by the first amplitude-changing rod and the second amplitude-changing rod. The amplitude is transmitted to the drum through the connecting shaft, so that the drum makes axial high-frequency low-amplitude vibration. Since the diameter of the output end of the amplitude-changing rod is smaller than the diameter of the notch of the connecting shaft, the rotation of the drum does not affect the axial vibration of the output end of the amplitude-changing rod in the notch. In addition, the rotation of the motor drives the rotation of the drum. Since the center line of the spline hole of the drum is eccentric to the axis of the drum by 2-10mm, the drum occurs radial vibration of power frequency and low amplitude while rotating. The simultaneous action of the axial high-frequency low-amplitude vibration and the radial power-frequency low-amplitude vibration of the drum realizes the radial extrusion and axial extrusion of the material on the screen, thereby improving the efficiency and quality of granulation.

[0033] It can be understood that those skilled in the art can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present application, and all such changes or replacements shall belong to the protection scope of the present application.
