Description

Technical Field

[0001] The invention relates to the technical field of granulators, and in particular to a metal magnesium powder granulator. Background Art

[0002] Magnesium powder granulation is the process of converting magnesium powder into particles by physical methods. Common granulation methods include wet granulation, spray granulation and dry granulation. Wet granulation is to add a wetting agent to the powder and then form particles by rolling, extrusion, etc.; spray granulation is to mix the powder with a liquid and then form particles by spray drying; dry granulation does not use a wetting agent and agglomerates the powder by mechanical force.

[0003] A Chinese patent document with announcement number CN213530760U discloses a metal powder granulator, including a mounting frame, a storage bin and a finished product bin. A hydraulic press is arranged in the mounting frame, and a plurality of extrusion heads are arranged at the lower end of the hydraulic press. A receiving plate is arranged below the extrusion head, and a plurality of through holes matching the extrusion heads are opened on the receiving plate. The storage bin is connected with the groove plate for feeding materials into the receiving plate. A scraper is installed at the upper end of the receiving plate, and the scraper is used to push the metal powder on the receiving plate into the through holes on the receiving plate. A bottom plate is installed below the receiving plate, and a discharge hole and a spherical groove are opened on the bottom plate. The bottom of the bottom plate is connected with the finished product bin. When the scraper pushes the material into the through hole, the groove on the bottom plate is aligned with the through hole, and the hydraulic press presses downward to drive the extrusion head to be pressed into the through hole, thereby pressing the metal powder into granules, and then the bottom plate slides to align the discharge hole with the through hole, so that the metal particles enter the finished product bin through the discharge hole.

[0004] In the above technology, since the lower half of the spherical metal particles is located in the groove, when the bottom plate slides, the bottom plate only pushes the upper half of the metal particles horizontally, so the metal particles will be crushed and cannot be separated from the groove and enter the discharge hole. Summary of the invention

[0005] The present invention provides a metal magnesium powder granulator, aiming to solve the problem in the related art that since the bottom plate only pushes the upper half of the metal particles horizontally, the metal particles will be crushed and the metal particles cannot be separated from the groove and enter the discharge hole.

An elastic telescopic rod four is installed between the lower pressing plate one and the lower pressing plate two to keep the two away from each other.

[0040] like Figure 2-Figure 4 As shown, the die assembly includes four upper pressing plates 54, four upper pressing plates 55 and a plurality of upper pressing rods. The upper pressing plates 54 and the upper pressing plates 55 correspond to each other one by one. The four upper pressing plates 54 are evenly distributed in the mounting frame 1 along the circumferential direction of the mounting frame 1. The upper pressing plate 54 is connected to the top plate of the mounting frame 1 through an elastic telescopic rod 56, so that the upper pressing plate 54 slides upward in the mounting frame 1. The upper pressing plate 54 and the upper pressing plate 55 are connected through an elastic telescopic rod 2 (not shown in the figure), so that the upper pressing plate 55 slides upward on the upper pressing plate 54.

When the upper surface of the abutment part 1 57 is flush with the upper surface of the upper pressure plate 2 55, the quarter spherical grooves at the lower ends of the upper left pressure rod 52 and the upper right pressure rod 53 form a hemispherical groove 9.

[0041] like Figure 2-Figure 6As shown, the die assembly also includes four lower pressing plates 1 64, four lower pressing plates 2 65 and multiple lower pressing rods. The lower pressing plates 1 64 and the lower pressing plates 2 65 correspond to each other one by one. The four lower pressing plates 1 64 are evenly distributed in the mounting frame 1 along the circumferential direction of the mounting frame 1. The lower pressing plates 1 64 are connected to the bottom plate of the mounting frame 1 by elastic telescopic rods 3 66, so that the lower pressing plates 1 64 slide downward in the mounting frame 1. The lower pressing plates 1 64 and the lower pressing plates 2 65 are connected by elastic telescopic rods 4 (not shown in the figure), so that the lower pressing plates 2 65 slide downward on the lower pressing plates 1 64. A downwardly protruding abutting portion 2 67 is provided on the lower end surface of the lower pressing plates 1 64, and a notch matching the abutting portion 2 67 is provided on the lower pressing plates 2 65. When the lower pressing plates 1 64 and the lower pressing plates 2 65 are tightly attached, The lower surface of the abutment part 2 67 is flush with the lower surface of the lower pressure plate 2 65. The lower pressure rod is cylindrical and is provided with multiple parts. The lower pressure rod is composed of a lower left pressure rod 62 and a lower right pressure rod 63 of left and right parts. The upper ends of the lower left pressure rod 62 and the lower right pressure rod 63 are both provided with a quarter spherical groove. The lower left pressure rod 62 is fixedly mounted on the upper end surface of the lower pressure plate 1 64, and the lower right pressure rod 63 is fixedly mounted on the upper end surface of the lower pressure plate 2 65. The lower pressure plate 1 64 is provided with multiple semi-cylindrical holes in the vertical direction. The lower right pressure rod 63 passes through the semi-cylindrical holes to form a lower pressure rod with the lower left pressure rod 62. When the lower surface of the abutment part 2 67 is flush with the lower surface of the lower pressure plate 2 65, the quarter spherical grooves at the upper ends of the lower left pressure rod 62 and the lower right pressure rod 63 form a hemispherical groove 9.

[0042] like Figure 1-Figure 9 As shown, the discharge assembly 7 includes a discharge hole 71, a pushing component 72, a slide 73 and an aggregate ring. The discharge hole 71 and the pushing component 72 are respectively located on opposite sides of the through hole 41. The pushing component 72 is used to push the particles into the discharge hole 71. A slide 73 is provided on the other side of the discharge hole 71 along the radial direction of the receiving plate 4. The bottom edge of the slide 73 gradually tilts downward outward along the radial direction of the receiving plate 4, and the slide 73 penetrates the outer peripheral surface of the receiving plate 4, so that the slide 73 is connected with the aggregate ring. The aggregate ring is sleeved on the outer peripheral wall of the mounting frame 1, and the aggregate ring is in an inclined state with one end higher than the other end, and a discharge port is installed at the lower end of the aggregate ring, and the discharge port is connected with the finished product bin 3.

[0043] like Figure 8-Figure 9 As shown, the pushing component 72 includes a pushing block 721 and an elastic member 722. The pushing block 721 and the material receiving plate 4 are connected by the elastic member 722. A slope 723 is provided on the pushing block 721. When the lower right pressure rod 63 moves upward in the through hole 41, it pushes the slope 723. When the slope 723 is pushed, the pushing block 721 will be pushed out of the through hole 41 into the material receiving plate 4.

[0044] like Figure 2-Figure 9As shown, the driving assembly 8 includes a driving motor 81, a driving shaft, an upper driving plate 82 and a lower driving plate 83. The output end of the driving motor 81 is connected to the driving shaft. The upper driving plate 82 and the lower driving plate 83 are both fixedly connected to the driving shaft. The upper driving plate 82 and the lower driving plate 83 are both semicircular bosses. The upper driving plate 82 is arranged above the upper pressing plate 2 55. The lower end surface of the upper driving plate 82 is sequentially provided with a connected inclined surface 2 821, a horizontal surface 822 and an inclined surface 3 823 along the circumference of the upper driving plate 82. The inclined surface 2 821 and the inclined surface 3 823 have the same inclination direction. When the upper driving plate 82 rotates, the inclined surface 2 821 first drives the upper pressing plate 2 55 to move downward and fit tightly with the upper pressing plate 1 54, and then Then, the upper pressing plate 1 54 and the upper pressing plate 2 55 are driven to move downward synchronously, thereby pressing the material in the through hole 41 into particles. When the horizontal plane 822 contacts the upper pressing plate 2 55, the height of the particles remains unchanged. When the inclined plane 3 823 contacts the upper pressing plate 2 55, the upper pressing plate 1 54 and the upper pressing plate 2 55 move downward synchronously again, thereby aligning the particles with the discharge port. When the lowest point of the inclined plane 3 823 leaves the upper pressing plate 2 55, the upper right pressing rod 53 detaches from the particles, and the push block 721 presses on the upper right side of the particles. When the lowest point of the inclined plane 3 823 leaves the upper pressing plate 1 54, the upper left pressing rod 52 detaches from the particles, and the push block 721 pushes the particles into the discharge port.

[0045] The lower driving plate 83 is located below the lower pressing plate 2 65, and the upper end surface of the lower driving plate 83 is provided with an inverted "V"-shaped inclined surface 4 831 and an inclined surface 5 832. When the lower driving plate 83 rotates, the inclined surface 4 831 drives the lower pressing plate 2 65 to move upward and close to the lower pressing plate 1 64, and then drives the lower pressing plate 2 65 and the lower pressing plate 1 64 to move upward synchronously. When the vertex at the connection between the inclined surface 4 831 and the inclined surface 5 832 contacts the lower pressing plate 2 65, the material in the through hole 41 is pressed into particles. After the lower pressing plate 2 65 passes over the inclined surface 4 831, the lower pressing plate 2 65 moves downward and separates from the lower pressing plate 1 64. After the lower pressing plate 1 64 passes over the inclined surface 4 831, it starts to move downward under the guidance of the inclined surface 5 832. At this time, the particles move downward driven by the upper pressing rod and the lower pressing rod until they are aligned with the discharge port.

[0046] The specific working principle of the present invention is:

[0047] First, add materials into the external silo 10, then start the motor and the feeding assembly 43, the motor drives the drive shaft to rotate, the rotation of the drive shaft drives the upper drive plate 82, the lower drive plate 83 and the scraper plate 42 to rotate around the axis of the drive shaft, the materials in the external silo 10 enter the front side of the scraper plate 42 under the conveyance of the feeding assembly 43, the scraper plate 42 pushes the materials into the through hole 41 when it rotates, when the scraper plate 42 completely passes under one of the upper pressure plates 54, the inclined surface 4 831 first drives the lower pressure plate 2 65 to be close to the lower pressure plate 1 64 when the lower drive plate 83 rotates, so that the lower left pressure rod 6 2 and the quarter spherical groove at the upper end of the lower right pressure rod 63 form a half spherical groove, and then drive the lower pressure plate 2 65 and the lower pressure plate 1 64 to move up and down synchronously, so that the hemispherical groove 9 at the upper end of the lower pressure rod is located above the discharge port, and then when the upper driving plate 82 rotates, the inclined surface 2 821 first drives the upper pressure plate 2 55 to move downward and close to the upper pressure plate 1 54, so that the quarter spherical groove at the lower end of the upper left pressure rod 52 and the upper right pressure rod 53 form a half spherical groove, and then drive the upper pressure plate 1 54 and the upper pressure plate 2 55 to move downward synchronously, so that the material in the through hole 41 The particles are pressed into particles. When the connection point of the four inclined planes 831 and the five inclined planes 832 passes the lower pressing plate 2 65, the lower pressing plate 2 65 moves downward under the action of the spring telescopic rod 4 and separates from the lower pressing plate 1 64. At this time, the lower left pressing rod 62 is separated from the particles. When the connection point of the four inclined planes 831 and the five inclined planes 832 passes the lower pressing plate 1 64, the lower pressing plate 1 64 starts to move downward under the action of the spring telescopic rod 3, and the three inclined planes 823 contact the upper pressing plate 2 55, thereby driving the upper pressing plate 1 54 and the upper pressing plate 2 55 to move downward synchronously again, so that the particles are driven downward by the upper pressing rod and the lower pressing rod. Move until it is aligned with the discharge port. When the lowest point of the inclined plane 3 823 leaves the upper pressing plate 2 55, the upper pressing plate 2 55 moves upward under the action of the spring telescopic rod 1. At this time, the upper right pressing rod 53 is separated from the particles, and the push block 721 presses on the upper right side of the particles to prevent the particles from adhering to the hemispherical groove 9 on the upper pressing rod. When the lowest point of the inclined plane 3 823 leaves the upper pressing plate 1 54, the upper left pressing rod 52 is separated from the particles, and the upper pressing plate 1 54 and the upper pressing plate 2 55 move upward under the action of the spring telescopic rod 2 to complete the reset, and the push block 721 pushes the particles into the discharge port. After the plane 2 is separated from the bottom of the lower pressing plate 1 64, the lower pressing plate 1 64 and the lower pressing plate 2 65 move downward under the action of the spring telescopic rod 3 to complete the reset.
