Description

Technical Field

[0001] This utility model relates to the field of drying mechanism technology, specifically a recycling drying mechanism for recycled plastic granules. Background Technology

[0002] Recycled plastics refer to plastic raw materials that are made from waste plastics through pretreatment, melt granulation, modification, and other processes, and can then be reused in production. Its core characteristic is resource recycling, reducing environmental pollution through recycling. After processing and pelletizing, recycled plastic granules retain a certain amount of moisture on their surface. If not dried promptly, this will affect the quality of the plastic. Most methods for drying plastic granules involve placing them in a tank, stirring them with a stirring rod, and then ventilating the tank to dry them. However, in this method, the plastic granules at the bottom of the tank have difficulty contacting the hot airflow, resulting in poor drying efficiency. To improve this situation, a recycled plastic granule circulating drying mechanism is proposed.

[0003] As disclosed in the authorization announcement number CN222201244U, a recycled plastic pellet circulating drying mechanism includes a tank and a support plate. A hot air fan is installed on the tank, and an exhaust pipe is installed at the output end of the hot air fan. A filter head is installed at the end of the exhaust pipe away from the hot air fan. The filter head facilitates the introduction of hot air into the interior of the tank while preventing plastic pellets from entering the exhaust pipe. The tank has a built-in stirring assembly.

[0004] Although it achieves the opposite rotation of the agitator on the rotating ring and the agitator blade in the stirring assembly, which disperses the plastic particles in the tank and flips the plastic particles at the bottom of the tank, thereby allowing the hot air to better dry the plastic particles and improve the drying efficiency and effect, the flipping assembly also tilts the tank, making it easy to discharge all the plastic particles in the tank and improving the practicality of the drying mechanism.

[0005] However, the existing drying mechanism does not solve the problems of not being able to supply air to multiple locations for stirring and drying plastic granules, nor is it conducive to flexibly adjusting the discharge position of plastic granules. It is also not conducive to circulating air supply for drying plastic granules and discharging plastic granules from different locations, which affects the drying effect and the flexibility of plastic granule discharge. Utility Model Content

[0006] The purpose of this invention is to provide a circulating drying mechanism for recycled plastic granules, in order to solve the problems mentioned in the background art, such as the inconvenience of multi-position air supply and stirring for drying plastic granules and the inability to flexibly adjust the discharge position of plastic granules, which are not conducive to circulating air supply for drying plastic granules and discharging plastic granules from different positions, thus affecting the drying effect and the flexibility of plastic granule discharge.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a recycled plastic granule circulating drying mechanism, comprising a drying tank and a drive base. The drive base is disposed at the center of the top of the drying tank. An air supply fan is disposed on the top of the drying tank on one side of the drive base. A feed inlet is disposed on the top of the drying tank on the side of the air supply fan. An exhaust fan is disposed on the top of the drying tank on the side of the feed inlet. An adapter frame is disposed outside the drive base. An adapter sleeve is disposed at the top of the adapter frame. A servo motor is disposed on the side wall of the drive base. The servo motor has a worm gear installed at its output end. A hollow shaft is movably installed inside a drive seat on one side of the worm gear. A worm wheel is fitted on the surface of the hollow shaft inside the drive seat, and the worm gear and the worm wheel mesh with each other. The hollow shaft extends into the interior of an adapter sleeve and is movably connected to the adapter sleeve. The hollow shaft extends into the interior of a drying tank, and multiple sets of stirring rods are symmetrically arranged at equal intervals on the surface of the hollow shaft. Scraper frames are symmetrically arranged on the side wall of the hollow shaft. Multiple sets of holes are provided on the surfaces of the hollow shaft, stirring rods, and scraper frames.

[0008] Preferably, the bottom end of the drying tank is provided with a connecting pipe, and the connecting pipe is movably connected to the drying tank.

[0009] Preferably, an adjusting motor is provided on the side wall of the drying tank, and a drive shaft is installed at the output end of the adjusting motor.

[0010] Preferably, a gear is fitted on the surface of the drive shaft, and a toothed ring is fitted on the surface of the connecting pipe on one side of the gear, with the gear and the toothed ring meshing with each other.

[0011] Preferably, the bottom end of the connecting pipe is provided with a discharge pipe, and the discharge pipe is movably installed with spiral blades.

[0012] Preferably, a stepper motor is provided on the side wall of the discharge pipe, and the output end of the stepper motor is connected to the spiral blade.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the drying mechanism not only realizes multi-position air supply and stirring drying of plastic granules and flexible adjustment of the discharge position of plastic granules, which facilitates the circulating air supply drying of plastic granules and the discharge of plastic granules from different positions, but also improves the drying effect of plastic granules and the flexibility of plastic granule discharge.

[0014] (1) The recycled plastic granules to be dried are poured into the inside of the drying tank through the feed port. The external air inlet pipe is connected to the adapter sleeve. The external drying gas is pumped into the inside of the stirring rod and the scraper through the hollow shaft. The gas is blown into the inside of the plastic granules through the holes on the surface of the hollow shaft, stirring rod and scraper. The plastic granules are dried by blowing air from the inside of the plastic granules. The diameter of the holes is smaller than the diameter of the plastic granules. The servo motor drives the worm to rotate. The worm drives the hollow shaft to rotate through the worm wheel. The hollow shaft drives the stirring rod and the scraper to rotate. The stirring rod and the scraper stir the plastic granules to make the gas contact with the plastic granules more even. The air supply fan sends air into the drying tank and the exhaust fan draws air out from the drying tank to form a circulating airflow in the upper space of the drying tank. The moisture is carried out from the inside of the drying tank and the plastic granules are dried by blowing air from the top of the plastic granules. This realizes multi-position air supply and stirring drying of plastic granules, which facilitates the circulating air supply drying of plastic granules and improves the drying effect of plastic granules.

[0015] (2) By opening the solenoid valve at the bottom of the drying tank, the plastic granules pass through the drying tank and the connecting pipe into the discharge pipe. The stepper motor drives the spiral blades to rotate, and the spiral blades drive the plastic granules to move and be discharged from the discharge pipe. When it is necessary to adjust the discharge position of the plastic granules, the adjustment motor drives the gear to rotate through the drive shaft, and the gear drives the connecting pipe to rotate through the gear ring, and the connecting pipe drives the discharge pipe to rotate, thereby adjusting the discharge position of the discharge pipe. This realizes the flexible adjustment of the discharge position of the plastic granules, which facilitates the discharge of plastic granules from different positions and improves the flexibility of plastic granule discharge.

The gas is blown into the plastic granules through the holes on the surface of the hollow shaft 3, stirring rod 4, and scraper 5, drying the plastic granules from the inside. The diameter of the holes is smaller than the diameter of the plastic granules. The servo motor 8 is turned on, and the servo motor 8 drives the worm gear 10 to rotate. With the worm gear 10 and the worm wheel 11 meshing with each other, the worm gear 10 drives the hollow shaft 3 to rotate through the worm wheel 11. 3 drives the stirring rod 4 and the scraper 5 to rotate, and the stirring rod 4 and the scraper 5 stir the plastic granules to make the gas contact with the plastic granules more evenly.

The external air inlet pipe is connected to the adapter sleeve 17, and external drying gas is pumped through the hollow shaft 3 to the inside of the stirring rod 4 and the scraper 5. The gas is blown into the plastic granules through the holes on the surface of the hollow shaft 3, stirring rod 4, and scraper 5, drying the plastic granules from the inside. The diameter of the holes is smaller than the diameter of the plastic granules. The servo motor 8 drives the worm gear 10 to rotate, and the worm gear 10 drives the hollow shaft 3 to rotate through the worm wheel 11.
