It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0026] Example 1

[0027] A particle preforming device, comprising a disc 11, a support bar 42, a bottom plate 44, a curved pipe 21, a straight pipe 23, and a motor 3; wherein a feeding port 15 is provided in the middle of the disc 11, a ring bar 41 is provided at the bottom edge, and an inner ring plate 14 is provided on the disc 11 at the bottom of the feeding port 15 and arranged along the edge of the feeding port 15, an outer ring plate 13 is provided at the bottom of the disc 11 on the inner side of the ring bar 41 and the outer side of the inner ring plate 14, and a convex tooth 32 is provided on the outer ring of the outer ring plate 13;

[0028] The support bar 42 is matched and slidably connected to the bottom of the ring bar 41, and the bottom of the support bar 42 is fixed to the bottom plate 44 directly below the disk body 11 through the support column 45. The motor 3 is fixed on the bottom plate 44, and the driving gear 31 is formed and fixed on the transmission shaft of the motor 3. The driving gear 31 is meshed with the convex teeth 32;

[0029] A curved pipe 21 is provided at the bottom of the discharge port 15, and the curved pipe 21 is fixed to the bottom plate 44 through a plurality of support rods 46, and the end of the curved pipe 21 is connected to the straight pipe 23 through a corrugated pipe 22;

[0030] The top edge of the curved pipe 21 is provided with a flange 24 extending outward, and the flange 24 and the top of the curved pipe 21 are matched and slidably connected between the inner ring plate 14 and the outer ring plate 13 .

[0031] The surface of the disk body 11 is an inclined surface which is low in the middle and high around.

[0032] The outer ring plate 13 is arranged along the outer edge of the feed opening 15 .

[0033] The support strip 42 is provided with a groove 43, the bottom of the ring strip 41 is provided with a half ball groove, the top of the support strip 42 is also provided with a half ball groove, and the ring strip 41 is connected in the groove 43 so that the half ball groove on the support strip 42 and the half ball groove on the ring strip 41 are connected together to form a ball groove 47, and a ball 410 is placed in the ball groove 47, and the support strip 42 and the ring strip 41 are in friction and rolling contact through the ball 410.

[0034] A half ball groove is provided on the top of the flange 24, and a half ball groove is also provided on the bottom of the disk body 11 between the inner ring plate 14 and the outer ring plate 13. The flange 24 and the top of the bent pipe 21 are connected between the inner ring plate 14 and the outer ring plate 13, so that the half ball groove on the top of the flange 24 and the half ball groove between the inner ring plate 14 and the outer ring plate 13 are connected together to form a second ball groove 48, in which a second ball 49 is placed, and the flange 24 and the bottom of the disk body 11 are in frictional rolling contact through the second ball 49.

[0035] A notch 411 is preset on the bottom plate 44 at a position corresponding to the corrugated tube 22 .

[0036] A vertical side guard plate 12 is welded to the outer peripheral edge of the top of the disk body 11 .

[0037] When in use, the motor 3 is turned on and the motor 3 works. The meshing transmission relationship between the driving gear 31 and the convex teeth 32 is utilized to drive the disc body 11 to rotate through the outer ring plate 13. The middle part of the bottom of the disc body 11 rotates along the flange 24 and the curved pipe 21 through the ball 49 in the ball groove 48. The bottom edge of the disc body 11 rotates along the support bar 42 through the ball 410 in the ball groove 47. The rotation speed of the disc body 11 is adaptively regulated according to the weight of the mass material.

[0038] Then, the granular mass to be formed is poured one by one onto the position of the disk 11 near the edge guard plate 12, and the mass falls on the rotating disk 11. Since there is friction between the mass and the top surface of the disk 11, the disk 11 will drive the mass to rotate. During rotation, the mass can use the centrifugal force of rotation to make its surface gradually tend to be spherical. At the same time, since the contact between the mass and the disk 11 is only frictional, and the inclined surface of the top surface of the disk 11 will cause the mass to roll under gravity. The mass eventually presents a vortex line motion trajectory on the top surface of the disk 11, rotating in a circle while rolling toward the lower feed port 15, so that the surface of the mass can contact the surface of the disk 11, and then transform under the action of rolling on the surface of the disk 11 and the centrifugal force. The mass with better preforming effect tends to be more spherical, and the mass with poor preforming effect tends to be more elliptical or other shapes. The mass with irregular surface can be preformed, which is more convenient for subsequent particle forming.

[0039] Since the utility model is a particle preforming device, it is not necessary for the particles to be completely formed. If it is desired that the agglomerates can be better formed, the rotation speed of the disc 11 and the residence time of the particles rotating on the disc 11 can be adjusted; preforming is to reduce the granulation time of the drum granulator and the extrusion granulator. The most time-consuming part of granulation is the initial preforming. Although the utility model cannot guarantee complete preforming, the particle preforming time can be reduced by centrifugal and vortex linear motion of the agglomerates on the disc 11.

[0040] Example 2

[0041] A particle preforming device comprises a disc body 11, wherein the top surface of the disc body 11 is arranged in an inclined surface which is low in the middle and high around, a feeding port 15 is preset at the center position of the disc body 11, a bent pipe 21 is installed at the bottom of the disc body 11 at the position of the feeding port 15, an outer ring plate 13 is installed at the bottom surface of the disc body 11 outside the feeding port 15, a convex tooth 32 is installed on the outer peripheral surface of the outer ring plate 13, the convex tooth 32 is meshed with a driving gear 31, and a motor 3 is installed on the driving gear 31.

[0042] A bottom plate 44 is provided directly below the disk body 11, the motor 3 is mounted on the bottom plate 44, a support bar 42 is also mounted on the bottom plate 44 via a plurality of support columns 45, a groove 43 is preset at the top of the support bar 42, a ring bar 41 extending into the groove 43 is mounted at a position corresponding to the support bar 42 on the bottom surface of the disk body 11, and the bent pipe 21 is supported and fixed to the bottom plate 44 via a plurality of support rods 46.

[0043] The curved pipe 21 is also connected to a straight pipe 23 , and the curved pipe 21 and the straight pipe 23 are connected via a corrugated pipe 22 .

[0044] The groove 43 and the bottom surface of the ring strip 41 at the corresponding position are provided with a corresponding ball groove 47, a ball 410 is placed in the ball groove 47, and the support strip 42 and the ring strip 41 are in frictional rolling contact through the ball 410.

[0045] An inner ring plate 14 is installed at the bottom of the disc body 11 at the feed opening 15 , and a flange 24 is installed at the top of the curved pipe 21 . The flange 24 and the curved pipe 21 extend between the inner ring plate 14 and the outer ring plate 13 .

[0047] A notch 411 is preset on the bottom plate 44 at a position corresponding to the corrugated tube 22 .

[0048] See also Figure 1-5 , a particle preforming device, comprising a preforming disc 1, a feeding pipe 2, a motor 3 and a support 4;

[0049] The preforming disc 1 is used to receive the mass to be formed into particles, and utilizes the rotational kinetic energy to gradually transform the irregular mass into relatively regular particles or elliptical materials. The preforming disc 1 comprises a disc body 11. The top surface of the disc body 11 is an inclined surface with a lower middle and higher surroundings. A vertical side guard plate 12 is welded and installed on the outer periphery of the disc body 11 to prevent the mass from being centrifugally thrown out when rotating. A discharge port 15 is preset at the center of the disc body 11. The diameter of the discharge port 15 is at least three times the diameter of the particles to be formed. For example, if the diameter of the fully formed particles is 1 cm, the diameter of the discharge port 15 is not less than 3 cm. The multiple diameter difference can ensure that even if the preforming of the mass is not ideal and is elliptical, it can still fall out of the discharge port 15 and will not be stuck at the discharge port 15.

[0050] The material discharge pipe fitting 2 is used to receive the preformed raw materials dropped out of the material discharge port 15 and guide them to the next workstation, such as an extrusion granulator. The material discharge pipe fitting 2 includes a curved pipe 21, a corrugated pipe 22 and a straight pipe 23. The ends of the curved pipe 21, the corrugated pipe 22 and the straight pipe 23 are connected in sequence. The end of the curved pipe 21 away from the corrugated pipe 22 abuts against the bottom surface of the disc body 11 at the position of the material discharge port 15. The curvature of the curved pipe 21 is a right-angle bend.

[0051] The motor 3 is used to drive the disc 11 to rotate, so that the mass material falling on the surface of the disc 11 has rotational kinetic energy. A driving gear 31 is installed on the shaft of the motor 3. An outer ring plate 13 is welded and installed on the bottom surface of the disc 11 outside the feeding port 15. A plurality of uniform convex teeth 32 are welded and installed on the outer peripheral surface of the outer ring plate 13. The driving gear 31 meshes with the convex teeth 32 for transmission.

[0052] The support member 4 is used to provide support for the preformed disc 1, the blanking pipe 2 and the motor 3. The support member 4 includes a ring bar 41, a support bar 42, a bottom plate 44 and a support column 45. The ring bar 41 is welded and fixed to the bottom surface of the disc body 11 near the periphery. The support bar 42 is arranged corresponding to the ring bar 41. The top surface of the support bar 42 is preset with a groove 43 corresponding to the ring bar 41. The ring bar 41 is rotatably supported in the groove 43. The bottom plate 44 is located directly below the support bar 42. The motor 3 is fixed to the top surface of the bottom plate 44. The top surface of the bottom plate 44 and the bottom surface of the support bar 42 are welded and fixed by multiple support columns 45. A support rod 46 welded to the bent pipe 21 is also welded and installed on the bottom plate 44.

[0053] When in use, the motor 3 is turned on, and the motor 3 works and rotates, and the meshing transmission relationship between the driving gear 31 and the convex teeth 32 is utilized to drive the disc body 11 to rotate. The speed needs to be adaptively adjusted according to the weight of the mass. Then, the granular mass to be formed is poured one by one onto the position of the disc body 11 near the side guard plate 12, and the mass falls on the rotating disc body 11. Due to the friction between the mass and the top surface of the disc body 11, the disc body 11 will drive the mass to rotate. During the rotation, the mass can use the centrifugal force of the rotation to make its surface gradually tend to be spherical. At the same time, due to the contact between the mass and the disc body 11, the mass There is only friction force, and the inclined surface setting on the top surface of the disk body 11 will make the agglomerate roll towards the lower feeding port 15 under gravity, and the agglomerate will eventually take a vortex line motion trajectory on the top surface of the disk body 11 while rotating in a circle and rolling towards the lower feeding port 15, so that the surface of the agglomerate can contact the surface of the disk body 11 one by one, and then change under the action of rolling on the surface of the disk body 11 and centrifugal force. The agglomerate with good preforming effect tends to be more spherical, and the agglomerate with poor preforming effect tends to be more elliptical. The agglomerate with an irregular surface can be preformed, which is more convenient in the subsequent particle forming.

[0054] In this embodiment, the groove 43 and the bottom surface of the ring strip 41 at the corresponding position are provided with corresponding ball grooves 47, the proportion of the ball groove 47 is three quarters of the support strip 42 and one quarter of the ring strip 41, and a ball 410 is placed in the ball groove 47, and the ball 410 is placed and fixed in the ball groove 47 at the position of the support strip 42, and the support strip 42 and the ring strip 41 are in frictional rolling contact through the ball 410.

[0055] The provision of the ball 1 410 reduces the friction resistance and wear between the ring strip 41 and the support strip 42, so that the disc body 11 rotates more smoothly and the rotation friction noise is also reduced.

[0056] In this embodiment, an inner ring plate 14 is welded to the bottom of the disk body 11 at the discharge port 15 , and a flange 24 is integrally formed on the top of the curved pipe 21 away from the corrugated pipe 22 . The flange 24 and the curved pipe 21 extend between the inner ring plate 14 and the outer ring plate 13 .

[0057] The arrangement of the inner ring plate 14 and the outer ring plate 13 forms a limit, and when the curved tube 21 extends between the inner ring plate 14 and the outer ring plate 13 , the lateral dislocation problem between the curved tube 21 and the curved tube 21 can be avoided when the disc body 11 rotates.

[0058] In this embodiment, corresponding ball grooves 48 are provided at the bottom of the disc body 11 between the flange 24 and the corresponding inner ring plate 14 and outer ring plate 13. The ball grooves 48 account for three quarters of the flange 24 and one quarter of the disc body 11. Balls 49 are placed in the ball grooves 48. Balls 49 are placed and fixed in the ball grooves 48 at the position of the flange 24. The flange 24 and the disc body 11 are in frictional rolling contact through ball 49.

[0059] The ball bearing 49 reduces the friction between the feed opening 15 and the plate body 11 and the curved pipe 21 . The curved pipe 21 can provide support for the plate body 11 from the feed opening 15 , and can be supported from two locations by the support bar 42 to ensure the stable support of the plate body 11 .

[0060] In this embodiment, a notch 411 is preset on the bottom plate 44 at a position corresponding to the corrugated tube 22 .

[0061] The notch 411 is provided to facilitate the bellows 22 to bend vertically downward, thereby forming a material cutting layout with the curved tube 21 being high and the straight tube 23 being low, for easy material cutting. Of course, relying on the bendable characteristics of the bellows 22, the straight tube 23 can also be bent horizontally for cutting to different positions.
