[0004] The purpose of this invention is to provide a particle drying device for the production of polytetrafluoroethylene propylene resin, which solves the problems that the device is not efficient and complete in drying polytetrafluoroethylene propylene resin particles, and that it is not easy to separate and discharge larger particles from smaller particles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a particle drying device for the production of poly(perfluoroethylene) propylene resin, comprising a base, a drying cylinder fixedly connected to the upper end of the base, a support plate fixedly connected inside the drying cylinder, a drying feeding mechanism provided on the support plate, a support cylinder fixedly connected to the upper end of the base, a vibration mechanism provided on the support cylinder, a guide ring fixedly connected to the outer side of the support cylinder, and a guide groove opened inside the base.

[0006] Preferably, the drying and feeding mechanism includes a motor, which is fixedly installed with a pallet. The output end of the motor passes through the pallet and is rotatably connected to it. A diverter pipe is fixedly connected to the lower end of the motor's output end. A conveying blade is fixedly connected to the outside of the diverter pipe and is rotatably connected to the drying cylinder. A hot air dryer is fixedly installed on the upper end of the pallet, located to the right of the motor. An annular groove is formed inside the diverter pipe, and the air inlet pipe of the hot air dryer passes through the pallet and is fixedly connected to it. The motor drives the diverter pipe to rotate, which in turn causes the conveying blade to rotate, moving the particles upward. Hot air is then injected into the diverter pipe by the hot air dryer and sprayed out to bake the particles, thus making the particle drying more efficient and complete.

[0007] Preferably, a baffle is fixedly connected to the outside of the air inlet pipe of the hot dryer, and the baffle is slidably connected to the diverter pipe. The baffle seals the annular groove.

[0008] Preferably, the vibration mechanism includes a screen, with the screen slidably connected inside the support cylinder, and a retaining ring fixedly connected inside the support cylinder, the retaining ring contacting the screen. A motor is fixedly mounted on the surface of the support cylinder, and the motor's shaft rotatably connects through the support cylinder. An eccentric wheel is fixedly connected to the left end of the motor's shaft, and a top block is slidably connected inside the eccentric wheel. A spring is installed inside the eccentric wheel. The motor drives the eccentric wheel to rotate, causing the top block to move and collide with the screen, thus vibrating the screen. This prevents the screen from clogging and allows large particles generated during screening to easily enter the guide ring, facilitating the diversion and discharge of the screened particles.

[0009] Preferably, a sliding pin is fixedly connected to the surface of the top block, and the sliding pin is slidably connected to the eccentric wheel. The sliding pin guides the movement of the top block.

[0010] Preferably, one end of the spring is fixedly connected to the top block, and the other end of the spring is fixedly connected to the eccentric wheel. By providing the spring, the top block can be easily reset.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a motor to drive the distribution pipe to rotate, which in turn causes the conveying knife to rotate and move the particles upward. Hot air is then sprayed into the distribution pipe through a hot air dryer to bake the particles, thus making the particle drying more efficient and complete.

[0013] 2. This utility model uses an electric motor to drive the eccentric wheel to rotate, which causes the top block to move and collide with the screen, thereby causing the screen to vibrate. This makes the screen less prone to clogging, and at the same time, it makes it easier for large particles generated during screening to enter the guide ring, so that the particles generated during screening can be easily diverted and discharged.

The output end of the motor 41 passes through the pallet 3 and is rotatably connected to the pallet 3. A diverter pipe 42 is fixedly connected to the lower end of the output end of the motor 41. A conveyor knife 43 is fixedly connected to the outside of the diverter pipe 42. The conveyor knife 43 is rotatably connected to the drying cylinder 2. A hot dryer 44 is fixedly installed at the upper end of the pallet 3 and to the right of the motor 41. An annular groove 45 is opened inside the diverter pipe 42. The air inlet pipe of the hot dryer 44 passes through the pallet 3 and is fixedly connected to the pallet 3. A baffle 46 is fixedly connected to the outside of the air inlet pipe of the hot dryer 44. The baffle 46 is slidably connected to the diverter pipe 42. By setting the baffle 46, the annular groove 45 is closed. The motor 41 drives the diverter pipe 42 to rotate, which in turn causes the conveyor knife 43 to rotate and move the particles upward. Hot air is sprayed into the diverter pipe 42 through the hot dryer 44 to bake the particles, thereby making the particle drying more efficient and complete.

[0022] Please see Figures 1-4 The vibration mechanism 6 includes a screen 61, which is slidably connected inside the support cylinder 5. A retaining ring 62 is fixedly connected inside the support cylinder 5, and the retaining ring 62 contacts the screen 61. A motor 63 is fixedly mounted on the surface of the support cylinder 5. The rotating shaft of the motor 63 passes through the support cylinder 5 and is rotatably connected. An eccentric wheel 64 is fixedly connected to the left end of the rotating shaft of the motor 63. A top block 65 is slidably connected inside the eccentric wheel 64. A sliding pin 66 is fixedly connected to the surface of the top block 65.

By setting the spring 67, the top block 65 can be easily reset. The eccentric wheel 64 is driven to rotate by the motor 63, which causes the top block 65 to move and collide with the screen 61, thereby causing the screen 61 to vibrate. This makes the screen 61 less prone to clogging. At the same time, it makes it easier for large particles generated during screening to enter the guide ring 7, and makes it easier for the particles generated during screening to be diverted and discharged.

Then the particles are poured into the drying cylinder 2, the conveying knife 43 conveys the particles, so that the falling speed of the particles is slowed down. The motor 41 drives the diversion pipe 42 to rotate, which in turn causes the conveying knife 43 to rotate and drive the particles to move upward. The hot air injected into the diversion pipe 42 by the hot air dryer 44 is sprayed out to bake the particles, so that the particles are dried more efficiently and completely. The dried particles fall onto the screen 61. The motor 63 is started, the motor 63 drives the eccentric wheel 64 to rotate, which causes the top block 65 to move and collide with the screen 61, which causes the screen 61 to vibrate, so that the screen 61 is not easy to clog. At the same time, it makes it easier for large particles generated by screening to enter the guide ring 1 to guide ring 7, so that the particles generated by screening are easily diverted and discharged.
