Description

Technical Field

[0001] The utility model relates to the technical field of modified recycled plastic particle production, in particular to a cooling and shaping device for the production of modified recycled plastic particles. Background Art

[0002] Modified recycled plastic pellets are made by physically or chemically modifying recycled waste plastics. These pellets offer improved properties, making them more suitable for specific applications. They are used in a variety of industries, including packaging, building materials, automotive parts, and electrical appliances. After extrusion, the modified recycled plastic pellets require cooling to solidify their shape, prevent them from clumping together, and ensure the individuality of the pellets for subsequent packaging and storage.

[0003] Patent authorization announcement number CN209665993U discloses a cooling silo for plastic pellet production, comprising a silo; a feed pipe provided at the top of the silo; a guide plate provided obliquely on the inner wall of the silo, below the feed pipe; a filter A provided on the side wall of the silo, below the guide plate; a fan provided on the side wall of the silo, outside the filter A; and a filter B provided at the top of the silo. Although the above patent can cool the plastic pellets by blowing with a fan, the blowing time during the falling process of the plastic pellets is limited, resulting in an insignificant cooling effect. Moreover, the blown plastic pellets will accumulate in the lower part of the silo after falling, and will be in close contact with each other, which is not conducive to the effective dissipation of heat, thereby extending the overall cooling time and reducing the cooling efficiency.

[0004] Therefore, there is a particular need for a cooling and shaping device for the production of modified recycled plastic particles to solve the problems existing in the prior art. Utility Model Content

The feed port 2 is connected to the left position of the top front side of the shell 1 by welding, and the motor 3 is connected to the left side of the top by bolts. The fan 5 is connected to the right front side of the outer wall of the upper part of the shell 1 by bolts, and the upper part of the shell 1 is rotatably connected to the dispersion disk 10 in the shape of a funnel. The feed port 2 is located above the dispersion disk 10 to ensure that the plastic particles poured into the inside of the shell 1 from the feed port 2 are in contact with the dispersion disk 10 in advance. The bottom of the shell 1 is connected to the discharge port 201 by welding, and the upper end of the discharge port 201 is connected to the discharge control valve 7 by bolts. The middle part of the dispersion disk 10 is connected to the air outlet 8 by welding. The upper end of the air outlet 8 passes through the outside of the shell 1, and the lower end is close to the discharge control valve 7. The ends are connected to the output shaft of the motor 3 by welding with a gear 301, and the two gears 301 are meshed with each other. The top of the fan 5 is connected to the air inlet pipe 4 by welding. The left end of the air inlet pipe 4 is rotatably connected to the upper end of the air outlet tube 8. A support plate is provided at the right position on the top of the shell 1 to support the upper end of the air inlet pipe 4 to ensure the stability of the air inlet pipe 4. The outside of the air outlet tube 8 is connected to the auger 9 by welding. The arc surface of the dispersion plate 10 is connected to a plurality of baffles 11 distributed in a circular manner by welding. The outside of the upper end of the air outlet tube 8 is connected to the center point by welding. There are multiple distributed air outlet branch pipes 12, the upper ends of the air outlet branch pipes 12 pass through the dispersion disk 10 and the corresponding baffle 11, and the lower ends of the multiple air outlet branch pipes 12 are connected to the stirring plate 13 by welding, and the stirring plate 13 is composed of stirring rods of different lengths, and there is a certain distance between the lower ends of the stirring rods and the inner wall of the outer shell 1 to prevent the stirring plate 13 from scratching the inner wall of the outer shell 1, and the lower ends of the multiple air outlet branch pipes 12 are connected to the air outlet ring 14 by welding, and the air outlet holes on the air outlet cylinder 8, the air outlet branch pipe 12 and the air outlet ring 14 are equidistantly distributed to ensure that the air flow is blown to different positions inside the outer shell 1.

[0023] Initially, the discharge port 201 is in a closed state. When the device needs to be used, first install the shell 1 in a suitable position and fix the support frame 6 on the ground, then turn on the fan 5 and the motor 3, and pour the plastic particles to be cooled into the shell 1 from the feed port 2. The plastic particles are pre-contacted with the dispersion disk 10 and dispersed into multiple portions by the baffle 11 and evenly fall into the shell 1. At this time, the fan 5 runs to transport the external air from the air inlet pipe 4 to the air outlet cylinder 8, the air outlet branch pipe 12 and the air outlet ring 14 in turn, and then blows the air flow to different positions in the shell 1 to cool the plastic particles.

At the same time, the air outlet tube 8 drives the auger 9 to rotate, and the plastic particles that have fallen to the lower part of the shell 1 are transported upward to the upper part of the shell 1 and fall again, and this reciprocating process increases the contact time between the plastic particles and the air flow. The air outlet branch pipe 12 also drives the stirring plate 13 to rotate, stirring the plastic particles in the lower part of the shell 1. When the plastic particles are cooled and shaped, the fan 5 and the motor 3 are turned off, and the discharge control valve 7 is controlled to open the discharge port 201 to discharge the plastic particles. After the discharge is completed, the discharge control valve 7 is controlled to close the discharge port 201. It is worth noting that during the cooling process, the air flow containing waste heat is discharged from the shell 1 through the feed port 2 to maintain air circulation.
