Description

Technical Field

[0001] This invention relates to the field of attapulgite ore granulation equipment, specifically to a granulation equipment for functional compound fertilizers using attapulgite ore. Background Technology

[0002] Attapulgite clay is a clay mineral with attapulgite as its main component. It is characterized by its fine texture, high water absorption, and stickiness and plasticity when wet. Using it as a binder in compound fertilizers results in high granulation rates, short granulation times, high-strength granules with good surface smoothness, and extended fertilizer retention time. Furthermore, using attapulgite clay as a binder can improve production capacity, reduce power consumption, and save on the amount of expensive raw materials such as talc and ammonium chloride.

[0003] Attapulgite clay can be used not only as a binder but also as a dispersant. For example, when preparing compound fertilizer granules using phytic acid as the phosphorus source, adding attapulgite clay can de-stick the sticky phosphorus and potassium substances, making it easier to mix and granulate. However, in existing technologies, the particle size may vary, which slows down production efficiency and affects the quality of the granules. Furthermore, particle size differences are common during production, often causing blockages. Therefore, a functional compound fertilizer granulation device using attapulgite clay is needed that can improve production efficiency while ensuring uniform particle size. Summary of the Invention

[0007] Preferably, the recycling mechanism includes a transverse chute located inside the extrusion roller. An auxiliary chute is located inside the recycling mechanism. An annular groove is slidably connected inside the transverse chute. An arc-shaped rod is fixedly connected to the side of the crushing roller and slidably connected inside the annular groove. The arc-shaped rod and the annular groove are connected by a telescopic component, allowing the rod to slide within the annular groove while simultaneously pulling it.

[0008] Preferably, the auxiliary mechanism includes a concave filter screen, which is fixedly connected to one end of the extrusion roller.

[0009] Preferably, the feeding mechanism includes a feeding port, which is opened on the surface of the extrusion roller. A fitting plate is rotatably connected inside the feeding port.

The trigger rod slides in the special-shaped groove when rotating. The inlet and outlet of the special-shaped groove are flared.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] In this invention, when the L-shaped rod moves, it passes over the inclined surface of the inclined block and is squeezed by the inclined block. When the L-shaped rod turns back, it is squeezed by the flat surface of the inclined block, which drives the L-shaped rod to rotate. The L-shaped rod drives the discharge plate to rotate, causing the convex receiving ring to open. At this time, the convex receiving ring is located on the side of the crushing roller. By centrifugal force, the unqualified raw materials continue to be discharged through the convex receiving ring, so that the crushing roller can crush again, ensuring the full utilization of the raw materials and the qualified rate of granulation.

[0012] In this invention, the large-diameter raw material entering the extrusion roller is refined by the rotation of the crushing roller, and the raw material is discharged through the C-shaped filter plate by centrifugal force. Some unprocessed raw material will remain inside the C-shaped filter plate for further processing. The raw material thrown out by centrifugal force will finally be discharged through the concave filter screen. At the same time, the concave filter screen can also block some unqualified raw material. The unqualified raw material will enter the convex receiving ring through the inclined surface of the concave filter screen for secondary processing. This can prevent unqualified raw material from being discharged and increase the utilization rate of raw material.

[0013] In this invention, the Z-shaped rod is driven to rotate by the slot. When the Z-shaped rod rotates, it drives the baffle at the other end to rotate within the fixed ring, closing the concave filter screen and preventing the discharged raw material from re-entering the extrusion roller. This ensures granulation efficiency. When the inclined chute moves outward, it drives the baffle to open, allowing the processed raw material to continue to be discharged. This forms an automatic circulating discharge system, processing and discharging large-diameter raw materials to further ensure uniform particle size and granulation qualification rate.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 17 This invention provides a technical solution: a granulation device for functional compound fertilizer using attapulgite clay, comprising a granulator body 1, a granulation outlet 2 on the side of the granulator body 1, and a large-diameter concave screen 3 fixedly connected to the upper end of the granulator body 1. Raw materials that cannot pass through the filter holes of the large-diameter concave screen 3 will enter the interior of the extrusion roller 71 through the lower opening of the large-diameter concave screen 3. A drive shaft 4 is fixedly connected to the output shaft inside the granulator body 1. A rotating granulation screen 5 is installed inside the granulator body 1 and is driven by the granulator body 1. The rotating granulation screen 5 and the rotating screen 5 rotate in opposite directions. The upper end of the drive shaft 4 is fixedly connected to the drive mechanism 6. The side of the drive mechanism 6 is fixedly connected to the raw material processing mechanism 7, which performs secondary processing on the raw material with a larger diameter. The inside of the raw material processing mechanism 7 is slidably connected to the recycling mechanism 8. The function of the recycling mechanism 8 is to process the raw material that has not been discharged again. The side of the raw material processing mechanism 7 is provided with an auxiliary mechanism 9 to prevent the discharged raw material from returning to the raw material processing mechanism 7. The other side of the raw material processing mechanism 7 is provided with a feeding mechanism 10.

[0034] The drive mechanism 6 includes a fixed platform 61, which is fixedly connected to the upper end of the drive shaft 4. A dual-shaft asynchronous motor 62 is fixedly connected to the upper surface of the fixed platform 61. The output shafts of the dual-shaft asynchronous motor 62 rotate in opposite directions. It is a modified version of an ordinary asynchronous motor, using a suitable mechanical transmission device and electrical control method to make the two shafts rotate in opposite directions. A rotating rod 63 is fixedly connected to the side of the output shaft of the dual-shaft asynchronous motor 62. A fixed sleeve 64 is rotatably connected to the surface of the rotating rod 63. One end of the fixed sleeve 64 is fixedly connected to the surface of the housing of the dual-shaft asynchronous motor 62. A limit groove 65 is fixedly connected to the surface of the fixed sleeve 64. The internal sliding connection of the 5 is a slide rod 66, the surface of the rotating rod 63 is fixedly connected to a wave rod 67, and the surface of the housing of the dual-shaft asynchronous motor 62 is rotatably connected to a hollow rod 68. When the slide rod 66 reciprocates, it drives the hollow rod 68 to rotate on the surface of the housing of the dual-shaft asynchronous motor 62 through the circulating inclined groove 69. The direction of rotation of the hollow rod 68 is opposite to that of the rotating rod 63. In this way, under the action of the double groove, it can not only decelerate, but also keep pace with the rotating granulation screen 5. The hollow rod 68 has a circulating inclined groove 69 inside. While the slide rod 66 slides inside the limiting slide groove 65, one end slides in the groove on the surface of the wave rod 67, and the other end is slidably connected inside the circulating inclined groove 69.

[0035] The raw material processing mechanism 7 includes an extrusion roller 71, which is fixedly connected to the surface of a hollow rod 68. The extrusion roller 71 rotates in the same direction as the rotating granulation screen 5 to extrude and granulate the raw material. A support plate 610 is fixedly connected inside the extrusion roller 71. A C-shaped filter plate 72 is fixedly connected to the surface of the support plate 610. A rotating groove 73 is fixedly connected to the surface of the support plate 610. A crushing roller 74 is rotatably connected inside the rotating groove 73. A bevel gear 75 is fixedly connected to the surface of the crushing roller 74. One end of a rotating rod 63 passes through the extrusion roller 71 and the support plate 610 and is rotatably connected within the extrusion roller 71 and the support plate 610. A bevel gear 76 is fixedly connected to one end of the rotating rod 63, and the bevel gear 76 meshes with the bevel gear 75.

[0036] The recycling mechanism 8 includes a transverse chute 81, which is located inside the crushing roller 71. An auxiliary chute 82 is also located inside the recycling mechanism 8. An annular groove 83 is slidably connected inside the transverse chute 81. An arc-shaped rod 84 is fixedly connected to the side of the crushing roller 74 and slides within the annular groove 83. The arc-shaped rod 84 and the annular groove 83 are connected by a telescopic component, allowing the rod to slide within the annular groove 83 while simultaneously pulling it. As the annular groove 83 gets closer to the arc-shaped rod 84, the telescopic component at the connection between the arc-shaped rod 84 and the annular groove 83 retracts, ensuring the normal operation of the device. During operation, the large-diameter raw material entering the extrusion roller 71 is refined by the rotation of the crushing roller 74, and the raw material is discharged through the C-shaped filter plate 72 by centrifugal force. Some unprocessed raw material will remain inside the C-shaped filter plate 72 for further processing. The raw material thrown out by centrifugal force will finally be discharged through the concave filter screen 91. At the same time, the concave filter screen 91 can also block some unqualified raw material. The unqualified raw material will enter the convex receiving ring 86 through the inclined surface of the concave filter screen 91 for secondary processing. This can prevent unqualified raw material from being discharged and increase the utilization rate of raw material.

[0037] One end of the annular groove 83 is fixedly connected to a convex receiving ring 86 via a connecting rod. An inclined groove 85 is fixedly connected to the inner side of the connecting rod between the convex receiving ring 86 and the annular groove 83. An L-shaped rod 88 drives the discharge plate 87 to rotate, causing the convex receiving ring 86 to open. At this time, the convex receiving ring 86 is located on the side of the crushing roller 74. Centrifugal force continues to discharge unqualified raw materials through the convex receiving ring 86. One side of the convex receiving ring 86 is rotatably connected to the discharge plate 87 via a torsion spring. An L-shaped rod 88 is fixedly connected to the side of the shaft of the discharge plate 87. The L-shaped rod 88 slides inside the auxiliary chute 82. A spring-loaded telescopic rod 89 is fixedly connected to the telescopic end of the spring-loaded telescopic rod 89, and an inclined block 810 is fixedly connected to it. When the L-shaped rod 88 moves, it passes over the inclined surface of the inclined block 810 and squeezes the inclined block 810. When the L-shaped rod 88 folds back, it is squeezed by the flat surface of the inclined block 810, which drives the L-shaped rod 88 to rotate. The L-shaped rod 88 drives the discharge plate 87 to rotate, which opens the convex receiving ring 86. At this time, the convex receiving ring 86 is located on the side of the crushing roller 74. Through centrifugal force, the unqualified raw materials continue to be discharged through the convex receiving ring 86, so that the crushing roller 74 can crush again, ensuring the full utilization of raw materials and the qualified rate of granulation.

[0038] The auxiliary mechanism 9 includes a concave filter screen 91, which is fixedly connected to one end of the extrusion roller 71. The raw material is discharged through the concave filter screen 91. The concave filter screen 91 can also block some unqualified raw materials. The unqualified raw materials will enter the interior of the convex receiving ring 86 through the inclined surface of the concave filter screen 91 for temporary storage. A fixing ring 92 is fixedly connected to one side of the concave filter screen 91, and a rotating ring 93 is fixedly connected to the edge of the fixing ring 92. The surface of the rotating ring 93 has a groove 94, and an extension rod 95 is fixedly connected to the surface of the rotating ring 93. The extension rod 95 is slidably connected inside the inclined groove 85, and the interior of the concave filter screen 91 is rotatably connected. A baffle 96 is fixedly connected to a Z-shaped rod 97 on its shaft. The Z-shaped rod 97 is slidably connected within a slot 94. The slot 94 drives the Z-shaped rod 97 to rotate. When the Z-shaped rod 97 rotates, it drives the baffle 96 at the other end to rotate within a fixed ring 92, closing the concave filter screen 91 and preventing the discharged raw material from re-entering the extrusion roller 71. This ensures granulation efficiency. When the inclined chute 85 moves outward, it drives the baffle 96 to open, allowing the processed raw material to continue to be discharged. This forms an automatic circulating discharge system, processing and discharging large-diameter raw materials to further ensure uniform particle size and granulation qualification rate.

[0039] The feeding mechanism 10 includes a feeding port 101, which is located on the surface of the extrusion roller 71. A fitting plate 102 is rotatably connected inside the feeding port 101. Two sets of fitting plates 102 are provided, and their shapes match the surface shape of the extrusion roller 71. A rotating rod 103 is fixedly connected to one end of the shaft of the fitting plate 102. A spring telescopic rod 104 is fixedly connected to the surface of the extrusion roller 71. A transverse groove 105 is fixedly connected to the telescopic end of the spring telescopic rod 104. The rotating rod 103... One end of the trigger rod 106 is slidably connected inside the transverse groove 105. A trigger rod 106 is fixedly connected to the back of the transverse groove 105. A crescent block 107 is fixedly connected to the upper end of the housing of the dual-axis asynchronous motor 62. The crescent block 107 and the extrusion roller 71 are on the same center. A special groove 108 is opened on the surface of the crescent block 107. The special groove 108 is composed of an arc groove and a straight groove. The trigger rod 106 will slide in the special groove 108 when rotating. The inlet and outlet of the special groove 108 at both ends are flared.

[0040] The method of use and advantages of this invention: The working process of this functional compound fertilizer granulation device utilizing attapulgite clay is as follows:

[0041] like Figures 1 to 17As shown, during use, the processed raw material is first placed into the granulator body 1 through the large-diameter concave mesh 3. Simultaneously, the granulator body 1 drives the drive shaft 4 and the rotating granulating mesh 5 to rotate. The drive shaft 4 and the rotating granulating mesh 5 rotate in opposite directions. When the drive shaft 4 rotates, it drives the upper fixed platform 61 to rotate. When the fixed platform 61 rotates, it drives the upper fixedly connected dual-shaft asynchronous motor 62 to rotate. The dual-shaft asynchronous motor 62 starts simultaneously and rotates in opposite directions. When the dual-shaft asynchronous motor 62 rotates, it drives the rotating rods 63 on both sides to rotate. When in motion, the wave rod 67, which is fixedly connected to the surface, rotates. When the wave rod 67 rotates, it causes the slide rod 66 to move along the inclined surface of its own corrugated groove. At the same time, it is limited by the limiting groove 65, causing the slide rod 66 to reciprocate back and forth inside the limiting groove 65. Meanwhile, when the slide rod 66 reciprocates, it causes the hollow rod 68 to rotate on the surface of the housing of the dual-shaft asynchronous motor 62 through the circulating inclined groove 69. The direction of rotation of the hollow rod 68 is opposite to that of the rotating rod 63. In this way, under the action of the double groove, it can not only decelerate, but also keep pace with the rotating granulation screen 5.

[0042] When the hollow rod 68 rotates, it drives the extrusion roller 71 to rotate. The extrusion roller 71 and the rotating granulation screen 5 rotate in the same direction to extrude and granulate the raw material. When the extrusion roller 71 rotates, it drives the trigger rod 106 to rotate. When the trigger rod 106 rotates, it enters the irregular groove 108 in the crescent block 107. The trigger rod 106 is on the arc groove in the irregular groove 108, and its frequency is consistent with its own rotation direction, until it enters the straight groove in the irregular groove 108. It will move along the inclined side of the straight groove, and the trigger rod 106 will... As the moving transverse groove 105 gradually moves upward, the transverse groove 105 drives the rotating rod 103 to rotate around the axis of the mating plate 102, and drives the mating plate 102 to rotate until the mating plate 102 is in the open state. At this time, the raw material that cannot pass through its own filter holes in the large-diameter concave mesh 3 will enter the interior of the extrusion roller 71 through the lower opening of the large-diameter concave mesh 3. As the extrusion roller 71 continues to rotate, the mating plate 102 will be closed through the other side of the shaped groove 108, so that the raw material is inside the extrusion roller 71.

[0043] Simultaneously, when the rotating rod 63 rotates, it drives the second bevel gear 76 to rotate, which in turn drives the first bevel gear 75 to rotate. The first bevel gear 75 rotates through the crushing roller 74, which in turn rotates through the rotating groove 73. The first bevel gear 75 is connected to the extrusion roller 71, and the second bevel gear 76 is connected to the rotating rod 63. The two rotate in opposite directions, so when the second bevel gear 76 rotates, it can drive the first bevel gear 75 to rotate. When the crushing roller 74 rotates, it refines the large-diameter raw material that enters the extrusion roller 71, and the raw material is discharged through the C-shaped filter plate 72 by centrifugal force. Some unprocessed raw material will remain inside the C-shaped filter plate 72 for further processing. The raw material thrown out by centrifugal force will finally be discharged through the concave filter screen 91. At the same time, the concave filter screen 91 can also block some unqualified raw material. The unqualified raw material will enter the convex receiving ring 86 through the inclined surface of the concave filter screen 91 for temporary storage.

[0044] When the crushing roller 74 rotates, it drives the arc-shaped rod 84 to rotate. The rotation of the arc-shaped rod 84 pulls the annular groove 83 to reciprocate within the transverse sliding groove 81. As the arc-shaped rod 84 pulls the annular groove 83, the annular groove 83 gets closer and closer to the arc-shaped rod 84. The telescopic component at the connection between the arc-shaped rod 84 and the annular groove 83 then contracts to ensure the normal operation of the device. When the annular groove 83 moves towards the extrusion roller 71, it pulls the convex receiving ring 86 via the connecting rod until the convex receiving ring 86 reaches the side of the crushing roller 74. The movement of the convex receiving ring 86 drives L... The L-shaped rod 88 moves simultaneously. When the L-shaped rod 88 moves, it first passes over the inclined surface of the inclined block 810 and squeezes the inclined block 810. When the L-shaped rod 88 turns back, it is squeezed by the flat surface of the inclined block 810, which drives the L-shaped rod 88 to rotate. The L-shaped rod 88 drives the discharge plate 87 to rotate, which opens the convex receiving ring 86. The convex receiving ring 86 is located on the side of the crushing roller 74 at this time. Through centrifugal force, the unqualified raw materials continue to be discharged through the convex receiving ring 86, so that the crushing roller 74 can crush again, ensuring the full utilization of raw materials and the qualified rate of granulation.

[0045] As the convex receiving ring 86 and the annular groove 83 move, the inclined groove 85 on the connecting rod in the middle moves simultaneously. When the inclined groove 85 moves, it squeezes the extension rod 95. When the inclined groove 85 moves inward, it pulls the extension rod 95 downward. The extension rod 95 then drives the rotating ring 93 to rotate. When the rotating ring 93 rotates, it drives the Z-shaped rod 97 to rotate through the slot 94. When the Z-shaped rod 97 rotates, it drives the baffle 96 at the other end to rotate within the fixed ring 92, closing the concave filter screen 91 and preventing the discharged raw material from re-entering the extrusion roller 71. This ensures the efficiency of granulation. When the inclined groove 85 moves outward, it drives the baffle 96 to open, allowing the processed raw material to continue to be discharged. This forms an automatic circulating discharge, processing and discharging large-diameter raw materials.
