Description

Technical Field

[0001] This utility model belongs to the technical field of cooling separation granulation device, and more specifically, it relates to an integrated countercurrent cooling cyclone separation granulation device. Background Technology

[0002] The counter-flow cooler represents the most advanced pellet feed cooling technology internationally. This new generation of cooling equipment, developed through research, is primarily used for cooling high-temperature pellet feed after pelleting. Its unique cooling mechanism involves the cooling air moving in the opposite direction to the hot, moist material, allowing the material to cool gradually from top to bottom. This avoids the surface cracking and poor heat dissipation issues common in vertical coolers caused by rapid cooling. The cooling effect is superior to existing domestic products of the same type. The cooled material temperature is no higher than the ambient temperature +5°C, and the moisture reduction rate is no less than 3.8%. This significantly contributes to producing high-quality pellet feed, extending its storage time, and improving economic efficiency.

[0003] Based on the above, the inventors have discovered the following problems: Current countercurrent cooling cyclone separation integrated pelleting devices can cool the high-temperature pelleted feed after pelleting during the pelleting process and then discharge it directly through the outlet. However, some pelleted feed tends to stick together and accumulate. These sticky and accumulated pelleted feeds are directly mixed with standard pelleted feeds and discharged through the outlet, which will affect the subsequent use effect of these pelleted feeds.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an integrated countercurrent cooling cyclone separation granulation device in order to achieve a more practical value. Utility Model Content

[0005] The purpose and effectiveness of this utility model's countercurrent cooling cyclone separation integrated granulation device are achieved through the following specific technical means:

[0006] A counter-current cooling cyclone separation integrated granulation device includes a workbench and a granulator mounted on top of the workbench. A feed hopper is installed on top of the granulator, and a discharge pipe is installed at the bottom. A granulation unit is installed inside the granulator, and a stirring assembly is installed below the granulation unit. An arc-shaped filter screen is installed inside the granulator, located below the stirring assembly. A conveying device is mounted on one side of the granulator via a support frame. The conveying device includes a discharge port located above one side of the granulator, a connecting pipe installed on one side of the discharge port, a discharge port located below the discharge port on one side of the granulator, and a connecting pipe installed on one side of the discharge port. The other ends of the connecting pipes are connected to a conveying pipe. A spiral conveying blade is rotatably connected inside the conveying pipe. A discharge port is located on one side of the conveying pipe near the connecting pipe, and a discharge port is located on one side of the conveying pipe near the connecting pipe. A cooler is installed on the side of the granulator away from the conveying pipe.

[0007] Furthermore, a motor is installed on the upper end face of the conveying pipe, and the output end of the motor passes through the conveying pipe and is connected to the spiral conveying blade.

[0008] Furthermore, the stirring assembly includes a rotating shaft installed inside the pellet mill, several stirring rods installed on the outside of the rotating shaft below it, an arc-shaped scraper installed at the bottom of the rotating shaft, and an arc-shaped filter screen installed below the arc-shaped scraper.

[0009] Furthermore, the granulation device includes a connecting rod fixedly installed above the rotating shaft, a rotating pressure roller movably installed on the connecting rod, a granulation plate fixedly installed below the rotating pressure roller, a cutting plate fixedly installed below the granulation plate, a cutter fixedly installed at the top of the cutting plate, and the cutting plate fixedly connected to the rotating shaft.

[0010] Furthermore, a second motor is installed on the top of the granulator, and the output end of the second motor passes through the granulator and is connected to the rotating shaft.

[0011] Furthermore, a collection box is installed below the workbench, and a handle is installed on one side of the collection box.

[0012] Furthermore, a valve is installed on the discharge pipe.

[0013] Furthermore, a control panel is installed on one side of the workbench.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By using the coordinated operation of the arc-shaped scraper, arc-shaped filter screen, connecting pipe two, conveying pipe, motor one, and spiral conveying blades, when the stirring rod agitates the cooled pelleted feed, qualified pellets pass through the arc-shaped filter screen and are discharged through the discharge pipe, while pellets that are stuck together fall onto the surface of the arc-shaped filter screen. Motor two drives the arc-shaped scraper to rotate via its shaft, pushing these stuck pellets to the discharge port one. The pellets then enter the conveying pipe through connecting pipe two and discharge port two. Then, motor one is started, driving the spiral conveying blades to rotate, which transport the pellets to the discharge port two. The pellets then re-enter the pellet mill through connecting pipe one and discharge port one. The pellet mill re-granulates these pellets, preventing unqualified pellets from mixing with qualified pellets, ensuring the uniformity and consistency of the final product, reducing raw material waste, lowering the processing cost of unqualified pellets, and further improving the practicality of the product.

[0026] Example:

[0027] As attached Figure 1 To be continued Figure 5 As shown:

[0028] This utility model provides an integrated countercurrent cooling cyclone separation granulation device, including a workbench 1 and a granulator 2 installed on top of the workbench 1. A feed hopper 3 is installed on the top of the granulator 2, and a discharge pipe 4 is installed on the bottom of the granulator 2. A granulation device is installed inside the granulator 2, and a stirring assembly is installed below the granulation device. An arc-shaped filter screen 5 is installed inside the granulator 2, located below the stirring assembly. A conveying device is installed on one side of the granulator 2 via a support frame. The conveying device includes a discharge port 6 located above one side of the granulator 2. A connecting pipe 7 is installed on one side of the feed inlet 6. A discharge port 8 is provided on one side of the granulator 2 below the feed inlet 6. A connecting pipe 9 is installed on one side of the discharge port 8. The other ends of the connecting pipe 7 and the connecting pipe 9 are connected to a conveying pipe 10. A spiral conveying blade 11 is rotatably connected inside the conveying pipe 10. A discharge port 12 is provided on one side of the conveying pipe 10 near the connecting pipe 7. A discharge port 13 is provided on one side of the conveying pipe 10 near the connecting pipe 9. A cooler 14 is installed on the side of the granulator 2 away from the conveying pipe 10.

[0029] The upper end face of the conveying pipe 10 is equipped with a motor 15, and the output end of the motor 15 passes through the conveying pipe 10 and is connected to the spiral conveying blade 11.

[0030] Through the coordinated use of the arc-shaped scraper 18, arc-shaped filter screen 5, connecting pipe 2 9, conveying pipe 10, motor 15, spiral conveying blades 11, and connecting pipe 17, when the stirring rod 17 stirs the cooled pelleted feed, the qualified pelleted feed passes through the arc-shaped filter screen 5 and is discharged through the discharge pipe 4, while the pelleted feed that is stuck together and piled up falls onto the surface of the arc-shaped filter screen 5. The motor 2 23 drives the arc-shaped scraper 18 to rotate through the rotating shaft 16. The arc-shaped scraper 18 pushes these stuck pelleted feeds to the position of the discharge port 18 by rotating. The pelleted feed is then conveyed through the connecting pipe 10. Pipe 2 9 and discharge port 2 13 enter the conveying pipe 10. Then, motor 15 is started, which drives the spiral conveying blade 11 to rotate. The spiral conveying blade 11 conveys the pellet feed to the discharge port 2 12. The pellet feed re-enters the pellet mill 2 through connecting pipe 1 7 and discharge port 6. The pellet mill re-granulates these pellet feeds, which can avoid the mixing of unqualified pellets with qualified pellets, ensure the uniformity and consistency of the final product, reduce raw material waste, reduce the processing cost of unqualified pellets, and further improve the practicality of the product.

[0031] The stirring assembly includes a rotating shaft 16 installed inside the pellet mill 2, several stirring rods 17 installed on the outside of the rotating shaft 16 below it, an arc-shaped scraper 18 installed at the bottom of the rotating shaft 16, and an arc-shaped filter screen 5 installed below the arc-shaped scraper 18.

[0032] The granulation device includes a connecting rod fixedly installed above the rotating shaft 16, a rotating pressure roller 19 movably installed on the connecting rod, a granulation plate 20 fixedly installed below the rotating pressure roller 19, a cutting plate 21 fixedly installed below the granulation plate 20, a cutter 22 fixedly installed at the top of the cutting plate 21, and the cutting plate 21 is fixedly connected to the rotating shaft 16.

[0033] With the coordinated use of the rotating shaft 16, rotating pressure roller 19, granulation plate 20, cutting plate 21 and cutting knife 22, the second motor 23 is started. The second motor 23 drives the rotating shaft 16 to rotate, which in turn drives the cutting plate 21 and cutting knife 22 to rotate. The connecting rod drives the rotating pressure roller 19 to roll at the top of the granulation plate 20, and the cutting plate 21 drives the cutting knife 22 to rotate at the bottom of the granulation plate 20. The material falls onto the granulation plate 20 and is squeezed by the rotating pressure roller 19 and then cut into shape by the cutting knife 22.

[0034] The granulator 2 is equipped with a second motor 23 on its top, and the output end of the second motor 23 passes through the granulator 2 and is connected to the rotating shaft 16.

[0036] A valve 25 is installed on the discharge pipe 4.

[0037] A control panel 26 is installed on one side of the workbench 1.

[0038] The specific usage and function of this embodiment are as follows:

[0039] Before using this invention, the integrity of the device must first be confirmed. During use, the material is first fed into the pellet mill 2 through the feed hopper 3. The motor 23 is started via the control panel 26. Motor 23 drives the rotating shaft 16 to rotate, thereby driving the pelleting device and mixing assembly. The connecting rod drives the rotating pressure roller 19 to roll at the top of the pelleting plate 20. The cutting plate 21 drives the cutter 22 to rotate at the bottom of the pelleting plate 20. The material falls onto the pelleting plate 20, is squeezed by the rotating pressure roller 19, and then cut into shape by the cutter 22. Simultaneously, the mixing rod 17 evenly mixes the cut pellets. At this time, the cooler 14 blows air to cool the pellets during the mixing process. Qualified pellets pass through the arc-shaped filter screen 5 and are discharged through the discharge pipe 4, while clumps of pellets fall onto the arc-shaped filter screen 5. On the surface of mesh 5, motor 23 drives the arc-shaped scraper 18 to rotate via shaft 16. The arc-shaped scraper 18 pushes the sticky pellets to the discharge port 8. The pellets enter the conveying pipe 10 through connecting pipe 9 and discharge port 13. Then, motor 15 is started, driving the spiral conveying blade 11 to rotate. The spiral conveying blade 11 conveys the pellets to the discharge port 12. The pellets re-enter the pellet mill 2 through connecting pipe 7 and discharge port 6. The pellet mill re-granulates these pellets, which can prevent unqualified pellets from mixing with qualified pellets, ensure the uniformity and consistency of the final product, reduce raw material waste, lower the processing cost of unqualified pellets, and further improve the practicality of the product.
