Description

Technical Field

[0001] This utility model relates to the technical field of granulators, specifically to a cooling device for the discharge port of a granulator. Background Technology

[0002] A pellet mill is a device used to process powdery or granular raw materials into granular products. The working principle of a pellet mill mainly involves a series of mechanical movements and material handling processes on the raw materials, including compression, extrusion, cutting, and granulation, ultimately forming the desired granular product. Rotary pellet mills are a common type of pelletizing equipment, offering high pellet formation rates, producing aesthetically pleasing pellets, and are suitable for assembly line operations.

[0003] Currently, the material particles produced by rotary pellet mills are discharged to the outside for collection via a hopper. However, during operation, the material is subjected to compression and friction within the machine, which generates heat and causes the temperature of the material particles to rise. High-temperature material particles are prone to deterioration and oxidation during storage and transportation, leading to a decline in material quality. After discharge, the material particles require additional cooling equipment, which increases energy consumption and costs. Utility Model Content

[0004] This utility model proposes a cooling device for the discharge port of a pellet mill. The cold air generated by the external refrigeration equipment is transported to the fixed ring through the connecting pipeline. The cold air blown out by multiple first air outlets is directly blown onto the hot material at the arc-shaped screen plate. Through heat exchange, the heat on the surface of the material is quickly removed, thereby performing preliminary cooling on the processed material.

[0005] Therefore, the technical solution adopted is as follows:

[0006] The working principle and beneficial effects of this application are as follows:

[0007] (1) The cold air generated by the external refrigeration equipment is transported to the fixed ring through the connecting pipeline. The cold air blown out by multiple first air outlets is directly blown onto the hot material at the arc screen plate. The heat on the surface of the material is quickly removed through heat exchange, thereby initially cooling the material. After the material is initially cooled, it rolls along the spiral channel formed by the conical block and the spiral baffle. The cold air blown out by multiple second air outlets can continuously blow onto the material in the spiral channel, further removing the heat from the material. The dual cooling design achieves a high-efficiency cooling effect on the material.

[0008] (2) The spiral baffles are arranged in a spiral shape along the outer surface of the conical block, guiding the material to move along the spiral channel formed during the descent, increasing the path of the material on the conical block. This design slows down the movement speed of the material on the conical block, which prolongs the heat exchange time between the material and the cold air, and further improves the cooling effect.

Detailed Implementation

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0016] like Figures 1-4 As shown, a cooling device for the discharge port of a pellet mill includes a pelletizing mechanism 1 and a collecting frame 2. The collecting frame 2 has a discharge port 4 on one side. The device is characterized in that: a support block 7 is fixed inside the collecting frame 2, a conical block 5 is fixed on the top of the support block 7, a spiral baffle 6 is fixed on the outer wall of the conical block 5, the pelletizing mechanism 1 is fixed on the top of the conical block 5, and a cooling mechanism 3 is provided on the top of the collecting frame 2. The cooling mechanism 3 includes a fixing ring 31 fixed to the top of the collecting frame 2 by a bracket. The fixing ring 31 has multiple evenly distributed first air outlets 32 on its inner side and multiple evenly distributed second air outlets 33 on its bottom. The outer wall of the fixing ring 31 is connected to a connecting pipe 34.

[0017] In this embodiment, the solution is a device for cooling materials produced by a granulator. Specifically, the granulation mechanism 1 is used to process powdered or granular raw materials into granular products and discharge the materials. In addition, by connecting the connecting pipe 34 to an external refrigeration device, the generated cold air is transported to the fixed ring 31 through the connecting pipe 34, and then discharged through multiple first air outlets 32 and second air outlets 33 respectively. The cold air blown out by the multiple first air outlets 32 blows directly onto the arc-shaped screen plate 13 in the granulation mechanism 1. The cold air comes into direct contact with the hot material and quickly removes the heat from the surface of the material, thereby initially cooling the produced material. Subsequently, the material rolls along the spiral channel formed by the conical block 5 and the spiral baffle 6 and is discharged into the collection frame 2. Finally, it is discharged through the discharge port 4. The cold air blown out by the multiple second air outlets 33 can blow onto the spiral channel, thereby further cooling the material during the feeding process and improving the cooling effect.

[0018] Among them, the spiral baffle 6 is arranged in a spiral shape along the outer surface of the conical block 5, guiding the material to move along a more tortuous path during the descent, thereby increasing the path of the material on the conical block 5. Due to the guidance of the spiral baffle 6, the moving speed of the material on the conical block 5 is slowed down, which prolongs the heat exchange time between the material and the cold air. The cold air is continuously blown towards the material through the air outlet on the fixed ring 31, and the slow movement of the material in the spiral channel ensures that the cold air can fully contact and remove the heat of the material, thereby improving the cooling efficiency of the cooling mechanism 3 for the material.

[0019] In addition, external refrigeration equipment can be a refrigerator or a cooler.

[0020] like Figure 1 As shown in the figure, the granulation mechanism 1 includes a granulation cylinder 11, which is fixed to the top of the conical block 5. The granulation cylinder 11 has a crushing component 12 inside and multiple arc-shaped sieve plates 13 on the outer wall of the granulation cylinder 11.

[0021] In this embodiment, by adding the mixed material into the granulation cylinder 11, the crushing component 12 works to squeeze the material outward. Under the pressure of the rotating grinding blade, the material passes through the holes of the arc-shaped screen plate 13, thereby forming granules.

[0022] like Figures 1-2 As shown, the fixing ring 31 is sleeved on the outside of the granulation cylinder 11.

[0023] In this embodiment, the cold air blown out by multiple first air outlets 32 is directly blown onto the arc-shaped sieve plate 13 in the granulation mechanism 1 to perform preliminary cooling on the material passing through the holes of the arc-shaped sieve plate 13. In addition, the cold air blown out by multiple second air outlets 33 can be blown onto the spiral channel to further cool the material during the feeding process.

[0024] like Figures 3-4 As shown, a vibration motor 8 is fixed on the side wall of the support block 7. A plurality of connectors 9 are fixed to the bottom of the support block 7. Each connector 9 includes a damper 91 and a spring 92 sleeved on the outside of the damper 91. The two ends of the damper 91 connect the support block 7 and the collection frame 2.

[0025] In this embodiment, the vibration motor 8 and the connecting piece 9 work together to control the cone block 5 and the spiral baffle 6 to vibrate, causing the material in the spiral channel to resonate. This helps to prevent the material from accumulating in the spiral channel and ensures that the material can roll smoothly along the spiral channel and be discharged.

[0026] Working principle:

[0027] By adding the mixed material into the granulation cylinder 11, the crushing component 12 works to squeeze the material outward. Under the pressure of the rotating grinding blade, the material passes through the holes of the arc-shaped screen plate 13, thus forming granules. By connecting the connecting pipe 34 to the external refrigeration equipment, the generated cold air is transported to the fixed ring 31 through the connecting pipe 34, and then discharged through multiple first air outlets 32 and second air outlets 33 respectively. The cold air blown out of the multiple first air outlets 32 blows directly onto the arc-shaped screen plate 13 in the granulation mechanism 1. The cold air comes into direct contact with the hot material and quickly removes the heat from the surface of the material, thus initially cooling the material. Subsequently, the material rolls along the spiral channel formed by the conical block 5 and the spiral baffle 6. At this time, the cold air blown out of the multiple second air outlets 33 can blow onto the spiral channel, thus further cooling the material during the feeding process. The material is discharged into the collection frame 2 along the spiral channel and finally discharged through the discharge port 4.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
