Description

Technical Field

[0001] This invention relates to the field of material processing technology, and more specifically, to a granulation apparatus. Background Technology

[0002] The production of granulated fertilizer has become a trend in fertilizer manufacturing. Granulated fertilizer offers advantages such as less dust during loading and unloading, less clumping during long-term storage, and easy and even distribution during application. Related technologies include granulation using roller presses and screw extruders. Taking a screw extruder as an example, the fertilizer is first heated until it becomes a viscous fluid. This fluid fertilizer is then fed into the screw extruder, where the extrusion plates apply pressure, pushing the fertilizer through a die to form granules. This granulation method is called extrusion molding. In addition, other granulation methods exist, such as grinding granulation and cutting granulation.

[0003] When granulating using the aforementioned granulation device, the fertilizer in a viscous state becomes solid fertilizer with insufficient compaction. This results in a loose granular fertilizer structure that is easily crushed, and also produces a lot of debris and powder, which can easily cause dust pollution. Therefore, the problem of loose granular fertilizer structure exists in this field. Summary of the Invention

[0004] The main objective of this invention is to provide a granulation device to solve the problem of loose granular fertilizer structure in related technologies.

[0005] To achieve the above objectives, the present invention provides a granulation apparatus, comprising: a base; a holding section rotatably disposed on the base and used to hold material to be granulated; an extrusion section movably disposed within the holding section and capable of reciprocating along a first preset direction to apply extrusion force to the material to be granulated, thereby forming a solid block material, wherein the first preset direction is perpendicular to and passes through the rotation axis of the holding section; an extrusion section disposed on the base, having an extrusion inlet and an extrusion outlet, wherein the solid block material enters the extrusion section from the extrusion inlet and forms a strip material, and the strip material is extruded from the extrusion outlet; and a cutting section disposed on the base, capable of cutting the strip material into granular material.

[0006] Furthermore, there are multiple extrusion sections, which are spaced apart around the rotation axis of the holding section.

[0007] Furthermore, the extrusion section includes a driving member, a linkage rod, and an arc-shaped extrusion plate. The driving member engages with the first end of the linkage rod to drive the linkage rod to move along a first preset direction. The arc-shaped extrusion plate is disposed at the second end of the linkage rod and located within the holding section.

[0008] Furthermore, the extrusion section also includes a guide rod and a guide sleeve fitted on the guide rod, one of the guide rod and the guide sleeve being mounted on the linkage rod, and the other of the guide rod and the guide sleeve being mounted on the base.

[0009] Furthermore, the arc-shaped extrusion plate and the linkage rod are inserted and fitted together, and the arc-shaped extrusion plate is movably disposed relative to the linkage rod along a first preset direction. The extrusion part also includes a first buffer member disposed between the arc-shaped extrusion plate and the linkage rod.

[0010] Furthermore, the driving component includes a first drive motor and a first gear connected to the output shaft of the first drive motor, and a rack is provided on the linkage rod to drive and cooperate with the first gear.

[0011] Furthermore, the holding section includes a holding cylinder and a rotating tray located at the bottom of the holding cylinder. The material to be granulated is placed in the holding space formed by the holding cylinder and the rotating tray, and the second end of the linkage rod passes through the cylinder wall of the holding cylinder.

[0012] Furthermore, a support member is provided on the base, which supports the middle of the rotating tray. The holding part also includes a second drive motor and a second gear connected to the output shaft of the second drive motor, which are provided on the base. The rotating tray has a mating tooth on its axial outer side, and the second gear drives the mating tooth to rotate.

[0013] Furthermore, the extrusion section is disposed between two adjacent extrusion sections.

[0014] Furthermore, the extrusion section includes an extrusion tube having an infeed section and an extrusion section that are interconnected, an extrusion inlet being formed at the free end of the infeed section, and an extrusion outlet being formed at the free end of the extrusion section, wherein the infeed section extends inward in a direction away from the rotation direction of the holding section.

[0015] Furthermore, the extrusion section is movably arranged along a second preset direction, wherein the second preset direction is perpendicular to the rotation axis of the holding section and passes through the rotation axis of the holding section, and the second preset direction is set at an angle to the first preset direction.

[0016] Furthermore, the granulation device also includes a support rod disposed on the base. The support rod includes a vertical section connected to the base and a transverse section connected to the upper end of the vertical section. The transverse section extends along a second preset direction. The extrusion section includes a connecting seat, an extrusion tube disposed on the connecting seat, and a sliding sleeve disposed on the connecting seat. The sliding sleeve is fitted onto the transverse section so that the extrusion section is movably disposed relative to the transverse section. Alternatively, the extrusion section includes a connecting seat, an extrusion tube disposed on the connecting seat, a sliding sleeve disposed on the connecting seat, a retaining ring disposed on the transverse section, and the sliding sleeve is fitted onto the transverse section and located on the side of the retaining ring near the rotation axis of the holding section. The extrusion section also includes a second buffer disposed between the retaining ring and the sliding sleeve.

[0017] Furthermore, the granulation device also includes a conveyor belt that extends away from the extrusion section and moves the strip material, and a cutting section located above the conveyor belt to cut the strip material on the conveyor belt into granular material.

[0018] Furthermore, the cutting section includes a rotating shaft disposed above the conveyor belt and cutting teeth disposed on the outer surface of the rotating shaft and extending along the length direction of the rotating shaft. The cutting teeth are fitted against the upper surface of the conveyor belt, and the length direction of the rotating shaft is set at an angle to the conveying direction of the conveyor belt.

[0019] Furthermore, the granulation device also includes a material receiving section and a material pump mounted on the base. The first end of the material pump is provided with a feed channel, and the end of the feed channel away from the material pump is provided with a filter element. The second end of the material pump is provided with a discharge channel, which extends toward the receiving section. The filter element is located inside the material receiving section.

[0020] Using the technical solution of this invention, a holding section, an extrusion section, an extrusion section, and a cutting section are all disposed on a base. The holding section is used to hold the material to be granulated and is rotatable relative to the base. The extrusion section is movable relative to the holding section and can reciprocate along a first preset direction. The extrusion section has an extrusion inlet and an extrusion outlet. The cutting section is used to cut the material to be granulated. Specifically, in use, the operator places the material to be granulated into the holding section. At this time, the material is in a viscous flow state. The holding section rotates, causing the viscous flow material to rotate. The extrusion section reciprocates along the first preset direction, continuously applying extrusion pressure to the viscous flow material so that it gradually becomes a solid block material. Then, the solid block material enters the extrusion section through the extrusion inlet, where it becomes a strip material. The strip material is discharged from the extrusion section through the extrusion outlet. Finally, the strip material is cut into granular material by the cutting section. Because the extrusion section reciprocates, it continuously compresses the material to be granulated. Simultaneously, the material rotates around the axis of rotation of the holding section. Therefore, after the viscous material transforms into a solid block, the circumferential outer wall of the solid block and the corresponding position of the extrusion section are continuously compressed. This makes the structure of the solid block more compact, resulting in a more compact structure of the final granular material. The granular material is less prone to crushing and less likely to produce debris or powder. Therefore, the technical solution of this application effectively solves the problem of loose granular fertilizer structure in related technologies. Attached Figure Description

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0039] like Figures 1 to 3 As shown, this application provides a granulation apparatus. An embodiment of the granulation apparatus of this application includes: a base 10; a holding section 20, rotatably disposed on the base 10 and used to hold the material to be granulated; an extrusion section 30, movably disposed within the holding section 20 and capable of reciprocating along a first preset direction a to apply extrusion pressure to the material to be granulated, causing it to form a solid block material 1, wherein the first preset direction a is perpendicular to and passes through the rotation axis of the holding section 20; an extrusion section 40, disposed on the base 10, having an extrusion inlet 41 and an extrusion outlet 42, wherein the solid block material 1 enters the extrusion section 40 from the extrusion inlet 41 and forms a strip material 2, and the strip material 2 is extruded from the extrusion outlet 42; and a cutting section 50, disposed on the base 10, capable of cutting the strip material 2 into granular material.

[0040] Using the technical solution of this embodiment, the holding part 20, the extrusion part 30, the extrusion part 40, and the cutting part 50 are all disposed on the base 10. The holding part 20 is used to hold the material to be granulated and is rotatable relative to the base 10. The extrusion part 30 is movable relative to the holding part 20 and can reciprocate along a first preset direction a. The extrusion part 40 has an extrusion inlet 41 and an extrusion outlet 42. The cutting part 50 is used to cut the material to be granulated. Specifically, during use, the operator places the material to be granulated into the holding section 20. At this time, the material to be granulated is in a viscous flow state. The holding section 20 rotates and drives the viscous flow material to rotate. The extrusion section 30 reciprocates along the first preset direction a. The extrusion section 30 continuously applies extrusion pressure to the viscous flow material so that the viscous flow material gradually becomes solid block material 1. Then, the solid block material 1 enters the extrusion section 40 through the extrusion inlet 41. The solid block material 1 becomes strip material 2. The strip material 2 is discharged from the extrusion section 40 through the extrusion outlet 42. Then, the strip material 2 is cut into granular material by the cutting section 50. Because the extrusion section 30 reciprocates, it continuously extrudes the material to be granulated. Simultaneously, the material rotates around the axis of rotation of the holding section 20. Therefore, after the viscous material transforms into solid block material 1, the circumferential outer wall of the solid block material 1 and the corresponding positions of the extrusion section 30 are continuously compressed. This makes the structure of the solid block material 1 more compact, resulting in a more compact structure of the final granular material. The granular material is less likely to be crushed and less likely to produce debris or powder. Therefore, the technical solution of this embodiment can effectively solve the problem of loose granular fertilizer structure in related technologies.

[0041] like Figure 1 As shown, there are multiple extrusion sections 30, which are spaced apart around the rotation axis of the holding section 20. Providing multiple extrusion sections 30 increases the frequency at which the circumferential outer wall of the solid block material 1 is compressed at the positions corresponding to the extrusion sections 30, thereby making the structure of the solid block material 1 more compact. In this embodiment, there are two extrusion sections 30, which are arranged opposite to each other.

[0042] like Figure 1 , Figure 2 As shown, the extrusion section 30 includes a driving member 31, a linkage rod 32, and an arc-shaped extrusion plate 33. The driving member 31 drives the first end of the linkage rod 32 to move the linkage rod 32 along a first preset direction a. The arc-shaped extrusion plate 33 is disposed at the second end of the linkage rod 32 and located within the holding section 20. The driving member 31 drives the linkage rod 32 to reciprocate along the first preset direction a, thereby causing the arc-shaped extrusion plate 33 to reciprocate along the first preset direction a within the holding section 20, thus achieving continuous extrusion of the solid block material 1.

[0043] like Figure 1, Figure 2 As shown, the extrusion section 30 also includes a guide rod 34 and a guide sleeve 35 sleeved on the guide rod 34. The guide rod 34 is disposed on the linkage rod 32, and the guide sleeve 35 is disposed on the base 10. The guide rod 34 and the guide sleeve 35 cooperate to guide the linkage rod 32 to move along the first preset direction a without deviating from the movement trajectory, so as not to affect the extrusion effect of the arc-shaped extrusion plate 33 on the solid block material 1. In other embodiments not shown in the figure, the guide sleeve may be disposed on the linkage rod, and the guide rod may be disposed on the base.

[0044] like Figure 1 , Figure 2 As shown, the arc-shaped extrusion plate 33 and the linkage rod 32 are interlocked, and the arc-shaped extrusion plate 33 is movably disposed relative to the linkage rod 32 along a first preset direction a. The extrusion part 30 also includes a first buffer member 36 disposed between the arc-shaped extrusion plate 33 and the linkage rod 32. In this embodiment, the first buffer member 36 is a compression spring. The arc-shaped extrusion plate 33 is provided with an insertion sleeve, and the arc-shaped extrusion plate 33 is inserted into one end of the linkage rod 32 through the insertion sleeve. There is a backlash space between the end face of the linkage rod 32 and the end face of the insertion sleeve away from the linkage rod 32. The linkage rod 32 is also provided with a retaining ring structure, and the two ends of the compression spring abut against the retaining ring structure and the insertion sleeve, respectively. When the solid block material 1 is extruded, the compression spring applies a first buffering force to the arc-shaped extrusion plate 33 in the direction of the solid block material 1, thereby realizing the buffering effect of the arc-shaped extrusion plate 33.

[0045] like Figure 1 , Figure 2 As shown, the driving component 31 includes a first driving motor 311 and a first gear 312 connected to the output shaft of the first driving motor 311. The linkage rod 32 is provided with a rack 321 that drives and engages with the first gear 312. The engagement of the first gear 312 and the rack 321 makes the reciprocating motion of the linkage rod 32 easy to achieve, with a simple structure and easy processing.

[0046] like Figure 1 , Figure 2 As shown, the holding section 20 includes a holding cylinder 21 and a rotating tray 22 located at the bottom of the holding cylinder 21. The material to be granulated is placed in the holding space formed by the holding cylinder 21 and the rotating tray 22. The second end of the linkage rod 32 passes through the cylinder wall of the holding cylinder 21. In this embodiment, the holding cylinder 21 and the rotating tray 22 are sealed together by a sealing strip. The rotation of the rotating tray 22 causes the solid block material 1 to rotate so that the area on the circumferential outer wall of the solid block material 1 corresponding to the extrusion section 30 can be extruded multiple times. The holding cylinder 21 is used to restrict the solid block material 1 to prevent it from leaving the holding space.

[0047] like Figure 1As shown, a support member 11 is provided on the base 10, and the support member 11 supports the middle of the rotating tray 22. The holding part 20 also includes a second drive motor 23 provided on the base 10 and a second gear 24 connected to the output shaft of the second drive motor 23. The rotating tray 22 has a mating tooth on its axial outer side, and the second gear 24 drives the rotating tray 22 to rotate by engaging with the mating tooth. In this embodiment, the support member 11 is a support shaft provided on the base and located at the center of the rotating tray 22. The support shaft is connected to the transverse section 61 (mentioned later) and extends downward. The rotating tray 22 is rotatably connected to the lower end of the support shaft and rotates around the support shaft. The second drive motor 23 drives the rotating tray 22 to rotate through the engagement between the second gear 24 and the mating tooth.

[0048] like Figure 1 As shown, the extrusion section 40 is disposed between two adjacent extrusion sections 30. The extrusion section 40 is disposed between two adjacent extrusion sections 30 to avoid interference between the extrusion section 40 and the extrusion section 30, so that the extrusion section 40 has sufficient space to contact the solid block material 1, thereby ensuring the extrusion effect of the extrusion section 40.

[0049] like Figure 1 , Figure 3 As shown, the extrusion section 40 includes an extrusion tube 43, which has an infeed section 431 and an extrusion section 432 that are interconnected. An extrusion inlet 41 is formed at the free end of the infeed section 431, and an extrusion outlet 42 is formed at the free end of the extrusion section 432. The infeed section 431 extends inward in a direction away from the rotation of the holding section 20. In use, because the infeed section 431 extends inward in a direction away from the rotation of the holding section 20, the solid block material 1 will squeeze the infeed section 431, so that the extrusion inlet 41 can cut the solid block material 1. This allows a portion of the solid block material 1 to enter the infeed section 431 and be shaped in the extrusion tube 43 into a strip material 2 whose contour matches the inner contour of the extrusion tube 43, for subsequent cutting processes.

[0050] It should be noted that the above-mentioned "extending section 431 inward along the direction of rotation away from the holding section 20" refers to, taking a cylindrical solid block material 1 as an example, the cross-section of the solid block material 1 is circular or nearly circular, and the extension direction of the extrusion section 431 is offset from the tangent line that passes through the contact point between the extrusion inlet 41 and the cross-section of the solid block material 1 and is tangent to the cross-section of the solid block material 1, with a certain angle (e.g., 0° to 10°) relative to the tangent line.

[0051] like Figure 1 , Figure 3As shown, the extrusion section 40 is movably arranged along a second preset direction b, wherein the second preset direction b is perpendicular to the rotation axis of the holding section 20 and passes through the rotation axis of the holding section 20, and the second preset direction b is set at an angle to the first preset direction a. The extrusion section 40 is movably arranged along the second preset direction b in order to more easily adjust the position of the extrusion section 40 so that the relative position of the extrusion section 40 and the solid block material 1 can meet the conditions for realizing the above-mentioned function of cutting the solid block material 1 into strip material 2 (that is, the extrusion section 431 can contact the solid block material 1 and extend inward in the direction away from the rotation of the holding section 20).

[0052] like Figure 1 , Figure 3 As shown, the granulation device also includes a support rod 60 disposed on the base 10. The support rod 60 includes a vertical section connected to the base 10 and a transverse section 61 connected to the upper end of the vertical section. The transverse section 61 extends along a second preset direction b. The extrusion section 40 includes a connecting seat 44, an extrusion tube 43 disposed on the connecting seat 44, a sliding sleeve 45 disposed on the connecting seat 44, a retaining ring 62 disposed on the transverse section 61, and the sliding sleeve 45 is sleeved on the transverse section 61 and located on the side of the retaining ring 62 close to the rotation axis of the holding section 20. The extrusion section 40 also includes a second buffer member 46 disposed between the retaining ring 62 and the sliding sleeve 45.

[0053] In this embodiment, the second buffer 46 is a compression spring, and the extrusion part 40 is movably disposed on the transverse section 61 of the support rod 60 through the sliding sleeve 45 and the connecting seat 44. The sliding sleeve 45 is also slidable relative to the transverse section 61. During use, regardless of the size of the solid block material 1, the second buffer 46 always applies a squeezing force toward the rotation axis of the holding part 20 to the sliding sleeve 45, thereby enabling the extrusion part 40 to always be pressed on the solid block material 1 to achieve the function of cutting and extruding the solid block material 1. That is, the extrusion part 40 can adapt to the position of the outer contour of the solid block material 1 without the need for frequent manual adjustment of the position of the extrusion part 40.

[0054] In other embodiments not shown, the extrusion section includes a connecting seat, an extrusion tube disposed on the connecting seat, and a sliding sleeve disposed on the connecting seat, the sliding sleeve being fitted onto the transverse section so that the extrusion section is movably disposed relative to the transverse section. In this embodiment, the extrusion section is movable relative to the transverse section of the support rod to facilitate adjustment of the extrusion section's position; however, when the extrusion section is adjusted into place relative to the solid block material, the operator uses fasteners to secure the sliding sleeve to the transverse section.

[0055] like Figure 1As shown, the granulation device also includes a conveyor belt 70, which extends away from the extrusion section 40 and moves the strip-shaped material 2. A cutting section 50 is located above the conveyor belt 70 to cut the strip-shaped material 2 on the conveyor belt 70 into granular material. In this embodiment, the granulation device also includes a guide plate 83, a discharge port 84, and a ball mill 85. The discharge port 84 is located at the end of the conveyor belt 70 away from the extrusion section 40 and is connected to the ball mill 85. The ball mill 85 grinds the granular material to make its outer surface more regular. The guide plate 83 is located between the discharge port 84 and the conveyor belt 70 to ensure that all granular material can enter the discharge port 84. Specifically, in this embodiment, the guide plate 83 forms a funnel-shaped guide channel, with the larger end of the funnel-shaped guide channel facing the conveyor belt 70, and the discharge port 84 located at the smaller end of the funnel-shaped guide channel.

[0056] like Figure 1 As shown, the cutting section 50 includes a rotating shaft 51 disposed above the conveyor belt 70 and cutting teeth 52 disposed on the outer surface of the rotating shaft 51 and extending along the length direction of the rotating shaft 51. The cutting teeth 52 are fitted against the upper surface of the conveyor belt 70, and the length direction of the rotating shaft 51 is angled to the conveying direction of the conveyor belt 70. In this embodiment, the rotating shaft 51 is perpendicular to the conveying direction of the conveyor belt 70. The rotation of the rotating shaft 51 drives the cutting teeth 52 to rotate, and the cutting teeth 52 cut the strip-shaped material 2 on the conveyor belt 70 into granular material.

[0057] like Figure 1 As shown, the granulation device also includes a material receiving section 81 and a material pump 82 disposed on the base 10. The first end of the material pump 82 is provided with a feed channel 821, and the end of the feed channel 821 away from the material pump 82 is provided with a filter element 822. The second end of the material pump 82 is provided with a discharge channel 823, which extends into the holding section 20. The filter element 822 is disposed inside the material receiving section 81. In use, the operator can either directly put the material to be granulated into the holding cylinder 21 through the opening, or put the material to be granulated into the material receiving section 81 and then pump the material to be granulated into the holding cylinder 21 using the material pump 82. The filter element 822 is a mesh sphere, which can filter out larger impurities in the material to be granulated in the material receiving section 81 before pumping the material to be granulated into the holding cylinder 21.

[0058] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0059] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0060] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
