Description

Technical Field

[0001] The invention relates to the technical field of granulation equipment, in particular to a granulation equipment for a soil conditioner. Background Art

[0002] Granulation equipment for soil conditioners primarily uses extrusion granulation, compressing powdered or granular raw materials into uniform granules through mechanical pressure. This typically involves a twin-roll extruder, where two counter-rotating rollers press the material into a die to form the granules. A vibrating screening system separates unformed material from finished granules. Some equipment also utilizes pneumatic assist, which helps propel granules out of the die.

[0003] However, traditional granulation equipment suffers from the following drawbacks: 1) The uniformity of finished granules is poor. The extrusion trough design of traditional granulation equipment is simple and lacks a dynamic pressure regulation mechanism, resulting in uneven pressure distribution. During the extrusion process, the material may deform due to insufficient or excessive local pressure, resulting in uneven granule size and even breakage or burrs. 2) Traditional granulation equipment relies solely on mechanical vibration or scraper cleaning, which cannot completely solve the problem of adhesion. This is especially true for high-humidity or sticky materials, which are prone to adhering to the extrusion trough, requiring frequent downtime for cleaning, affecting continuous production efficiency. 3) Traditional granulation equipment relies on a single conveyor belt or gravity separation, which cannot accurately distinguish between the two types of materials. Unformed materials are mixed with finished granules, requiring additional screening steps, increasing energy consumption and time costs. 4) Traditional granulation equipment has redundant drive systems, low transmission efficiency, and insufficient gas utilization in the pneumatic assist device. This results in high energy consumption during the extrusion and separation processes, resulting in high equipment operating costs. 5) Traditional granulation equipment lacks a modular design, and key components (such as the die trough and air pipe) are prone to clogging or wear. Furthermore, the equipment's complex internal structure makes cleaning and maintenance difficult, resulting in long downtime and high maintenance costs. Summary of the Invention

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] Example 1

[0023] refer to Figure 1-3The granulation equipment shown includes a granulation box 1, in which two sets of relatively rotating squeezing rollers 2 are provided. The squeezing rollers 2 are provided with a plurality of squeezing grooves 21. The squeezing rollers 2 are hollow. A discharge assembly 3 is provided on the squeezing rollers 2. The discharge assembly 3 includes a plurality of discharge units, a push ring 32 and a push block 33. The discharge unit includes an exhaust pipe 311. The exhaust pipe 311 is slidably fitted on the inner wall of the squeezing roller 2. An air outlet is provided on the squeezing groove 21, and an air guide hole is provided on the exhaust pipe 311. When the extrusion roller 2 rotates, it can drive the exhaust pipe 311 to move, so that the exhaust pipe 311 circulates and moves on the pushing ring 32 and the pushing block 33. The pushing block 33 is fixedly installed on the side wall of the pushing ring 32 near the bottom. When the exhaust pipe 311 moves onto the pushing ring 32, the air outlet and the air guide hole are staggered. When the exhaust pipe 311 moves onto the pushing block 33, the pushing block 33 pushes the exhaust pipe 311 to move, so that the air guide hole moves to correspond to the air outlet, thereby connecting the exhaust pipe 311 and the extrusion groove 21.

[0024] The material is placed in the granulation box 1, and the material enters between the two squeezing rollers 2. The two squeezing rollers 2 squeeze the material, and the material enters the extrusion groove 21 and is compacted as it is squeezed. The extrusion grooves 21 of the two squeezing rollers 2 squeeze the material into granules. The exhaust pipe 311 located above the squeezing roller 2 is against the pushing ring 32, and the air guide holes on the exhaust pipe 311 are staggered with the air outlet holes in the extrusion groove 21. As the squeezing roller 2 rotates, the material on the squeezing roller 2 rotates accordingly, and the squeezing roller 2 drives the exhaust pipe 311 to move. When the exhaust pipe 311 moves to the bottom of the squeezing roller 2, the exhaust pipe 311 is against the pushing block 33, and the pushing block 33 squeezes the exhaust pipe 311 to move, so that the air guide holes on the exhaust pipe 311 correspond to the air outlet holes in the extrusion groove 21, and the pressurized gas in the exhaust pipe 311 enters the extrusion groove 21 through the air guide holes and the air outlet holes, pushing out the material in the extrusion groove 21.

[0025] The material is squeezed into the extrusion groove 21 by the two extrusion rollers 2, so that the material is formed, and the continuous molding efficiency of the material is higher. The size of the extruded particles is limited by the extrusion groove 21, the size of the formed particles is more uniform, and the granulation effect is better. When the two extrusion rollers 2 squeeze the material into the extrusion groove 21, the air outlet holes opened on the extrusion groove 21 are closed by the exhaust pipe 311 to ensure that sufficient extrusion pressure is formed in the extrusion groove 21, preventing the material in the extrusion groove 21 from being discharged through the air outlet holes, which has a better extrusion molding effect on the material. When the material moves to the bottom position of the extrusion roller 2 with the extrusion roller 2, the exhaust pipe 311 is moved by the extrusion of the pushing block 33, and the air guide holes on the exhaust pipe 311 are connected with the air outlet holes on the extrusion groove 21. The pressurized gas in the exhaust pipe 311 enters the extrusion groove 21 to push out the material in the extrusion groove 21, and can push out the extruded material particles in the extrusion groove 21, preventing the material from adhering to the extrusion groove 21 due to extrusion, and having a better material feeding effect.

[0026] The pushing block 33 is arranged in an arc shape to prevent the exhaust pipe 311 from being stuck, and enables the exhaust pipe 311 to move onto the pushing block 33 as it rotates.

[0027] A rolling ball is rotatably installed at one end of the exhaust pipe 311 close to the push ring 32. The exhaust pipe 311 moves on the push ring 32 and the push block 33 through the rolling ball, reducing the friction between the exhaust pipe 311 and the push ring 32 and the push block 33, making the movement smoother, less likely to get stuck and reducing wear.

[0028] Further, refer to Figure 1-3 A discharge assembly 4 is also provided below the extrusion roller 2. The discharge assembly 4 includes a perforated conveyor belt 41 and a discharge plate 42. A plurality of discharge holes are provided on the perforated conveyor belt 41. The spacing between the plurality of discharge holes is the same as the spacing between the plurality of extrusion grooves 21. The extrusion roller 2 is against the perforated conveyor belt 41. The discharge plate 42 is provided in the perforated conveyor belt 41. The discharge plate 42 is inclined. The perforated conveyor belt 41 rotates in the opposite direction to the extrusion roller 2.

[0029] When the squeezing roller 2 rotates, the perforated conveyor belt 41 contacts the bottom of the squeezing roller 2 and rotates in the opposite direction of the squeezing roller 2. After the two squeezing rollers 2 extrude the material into shape, the material follows one of the squeezing rollers 2 to rotate between the squeezing roller 2 and the perforated conveyor belt 41. When the perforated conveyor belt 41 rotates, the discharge holes on the perforated conveyor belt 41 correspond to the squeezing groove 21 on the squeezing roller 2. The exhaust pipe 311 at the bottom of the squeezing roller 2 pushes the material particles in the squeezing groove 21 out of the squeezing groove 21 and enters the perforated conveyor belt 41 through the discharge holes. The granular material in the perforated conveyor belt 41 passes through the discharge holes. The material is discharged through the discharge plate 42. When the two extrusion rollers 2 extrude the material into the extrusion groove 21, part of the material will be squeezed through the gap between the two extrusion rollers 2. This part of the material cannot enter the extrusion groove 21 for extrusion into granules. The granular material in the extrusion groove 21 enters the discharge plate 42 through the discharge hole for discharge, while the material outside the extrusion groove 21 is located between the extrusion rollers 2 and the perforated conveyor belt 41 and is transmitted. The material outside the extrusion groove 21 and the granular material in the extrusion groove 21 can be separated. The surface of the formed granular material is more regular, without defects such as burrs, and the granulation effect is better.

[0030] Further, refer to Figure 1-3 The discharging unit also includes a compression spring 312, an air supply pipe 313, a fixed plate and a sliding block 314. The sliding block 314 is fixedly mounted on the inner wall of the squeezing roller 2. The exhaust pipe 311 passes through the sliding block 314 and slides with the sliding block 314. The air supply pipe 313 is inserted into the exhaust pipe 311 and slides with the exhaust pipe 311. The fixed plate is fixedly mounted on the air supply pipe 313. One end of the compression spring 312 is fixedly mounted on the fixed plate, and the other end of the compression spring 312 is fixedly mounted on the exhaust pipe 311. The compression spring 312 is sleeved on the air supply pipe 313.

[0031] The compression spring 312 compresses the exhaust pipe 311 and presses the exhaust pipe 311 onto the pushing ring 32. As the exhaust pipe 311 moves, the exhaust pipe 311 is against the pushing block 33. The pushing block 33 squeezes the exhaust pipe 311 to move, and the exhaust pipe 311 compresses the compression spring 312. When the exhaust pipe 311 moves from the pushing block 33 to the pushing ring 32, the compression spring 312 pushes the exhaust pipe 311 to move onto the pushing ring 32. The compression spring 312 can press the exhaust pipe 311 onto the pushing ring 32, and the air supply pipe 313 passes pressurized gas into the exhaust pipe 311. When the exhaust pipe 311 moves, it slides on the air supply pipe 313 and remains connected with the air supply pipe 313.

[0032] Further, refer to Figure 1-3 The discharging assembly 3 also includes a rotating air pipe 34, a fixed air pipe 35, an air pump 36, a fixed frame and a fixed rod 37. The air pump 36 is fixedly mounted on the outer wall of the granulation box 1, one end of the fixed air pipe 35 is fixedly mounted on the air pump 36, and the other end of the fixed air pipe 35 passes through the side wall of the granulation box 1. The rotating air pipe 34 is rotatably connected to the fixed air pipe 35, the air supply pipe 313 is fixedly mounted on the rotating air pipe 34 and communicates with the rotating air pipe 34, the fixed frame is fixedly mounted in the fixed air pipe 35, the fixed rod 37 is fixedly mounted on the fixed frame, the fixed rod 37 passes through the rotating air pipe 34 and is rotatably connected to the rotating air pipe 34, and the fixed rod 37 is fixedly mounted to the push ring 32.

[0033] The air pump 36 passes the pressurized gas into the fixed air pipe 35, the fixed air pipe 35 passes the pressurized gas into the rotating air pipe 34, the rotating air pipe 34 passes the pressurized gas into the air supply pipe 313, and the air supply pipe 313 passes the pressurized gas into the exhaust pipe 311. When the exhaust pipe 311 rotates following the squeezing roller 2, the exhaust pipe 311 drives the air supply pipe 313 to rotate, and the air supply pipe 313 drives the rotating air pipe 34 to rotate. The rotating air pipe 34 rotates on the fixed air pipe 35 and remains connected with the fixed air pipe 35, which can solve the air supply problem of the exhaust pipe 311 when it can move and rotate following the squeezing roller 2.

[0034] The fixed air pipe 35 is fixedly mounted on the granulation box 1, and the fixed frame is fixedly mounted in the fixed air pipe 35. The fixed frame will not close the fixed air pipe 35, ensuring the flow of pressurized gas in the fixed air pipe 35. One end of the fixed rod 37 is fixedly mounted on the fixed frame, and the other end is fixedly mounted on the push ring 32 to fix the push ring 32 and prevent the push ring 32 from rotating. The push ring 32 is rotatably connected to the extrusion roller 2.

[0035] Further, refer to Figure 1-3The granulation box 1 is also provided with a driving assembly, which includes a driving motor 51 and two driving gears 52. A driving shaft is fixedly installed at one end of the extrusion roller 2. The two driving shafts pass through the granulation box 1 and are rotatably connected to the granulation box 1. The two driving gears 52 are respectively fixedly mounted on the corresponding driving shafts. The two driving gears 52 are meshed with each other, and the driving motor 51 is fixedly mounted on one of the driving shafts.

[0036] The driving motor 51 drives one of the driving shafts to rotate, the corresponding driving shaft drives the corresponding squeezing roller 2 to rotate and drives the corresponding driving gear 52 to rotate, the corresponding driving gear 52 drives the other driving gear 52 to rotate, and the other driving gear 52 drives the corresponding squeezing roller 2 to rotate, and the two driving gears 52 rotate in opposite directions. The squeezing rollers 2 driven by the two driving gears 52 rotate in opposite directions, and can drive the two squeezing rollers 2 to rotate and rotate in opposite directions.

[0037] Further, refer to Figure 1-3 The discharge assembly 4 also includes two driving rollers 43 and a discharge motor 44. The two driving rollers 43 are rotatably connected to the granulation box 1. The discharge motor 44 is fixedly mounted on the granulation box 1. The output end of the discharge motor 44 is fixedly mounted on one of the driving rollers 43. The punched conveyor belt 41 is sleeved on the two driving rollers 43.

[0038] The discharge motor 44 drives the driving roller 43 to rotate, and the driving roller 43 drives the punching conveyor belt 41 to rotate.

[0039] Further, refer to Figure 1-3 Two gathering rollers 6 are also provided in the granulation box 1, and a connecting shaft is fixedly installed on the gathering roller 6, and the connecting shaft is rotatably connected to the granulation box 1. The driving assembly also includes two belt units 53, and the belt unit 53 includes a driving pulley, a passive pulley and a driving belt. The driving pulley is fixedly sleeved on the driving shaft, and the passive pulley is fixedly sleeved on the connecting shaft, and the driving belt is connected to the driving pulley and the passive pulley.

[0040] When the driving shaft rotates, it drives the active pulley to rotate, the active pulley drives the driving belt to rotate, the driving belt causes the passive pulley to rotate, and the passive pulley drives the gathering roller 6 to rotate through the connecting shaft, so that when the squeezing roller 2 rotates, it drives the gathering roller 6 to rotate. The two gathering rollers 6 can initially gather and squeeze the material, making the material falling onto the squeezing roller 2 more compact, preventing the squeezing roller 2 from squeezing the material and causing cavities in the material, and the quality of the extruded granular material is better.

[0041] Further, refer to Figure 1-3A fixed scraper 7 and a connecting scraper 8 are fixedly installed in the granulation box 1.

A granulation outlet is provided at the position of the discharge plate 42 of the granulation box 1. A discharge inclined plate 10 is fixedly installed at the position of the granulation outlet of the granulation box 1.

[0042] The granular material in the extrusion groove 21 on the extrusion roller 2 enters the discharge plate 42, and the granular material rolls and slides under the tilting action of the discharge plate 42, and is discharged through the discharge inclined plate 10, rounding the granular material, further making the surface of the material more regular and smooth, and improving the granulation quality. The material on the surface of the extrusion roller 2 is scraped off by the fixed scraper 7, and part of the material adhering to the perforated conveyor belt 41 is scraped off by the connecting scraper 8. The scraped material is discharged through the discharge inclined plate 9 and is recovered for granulation again.

[0043] A vibrator is installed on the discharge plate 42 to vibrate the discharge plate 42 so that the granular material is discharged more quickly.
