Description

Technical Field

[0001] This utility model relates to the field of PC particle processing technology, specifically to a dryer for PC particles that are heated evenly. Background Technology

[0002] PC granules are polycarbonate granules. Polycarbonate is a high molecular polymer containing carbonate groups in its molecular chain. Due to the special structure of polycarbonate, it has become the fastest-growing general-purpose engineering plastic among the five major engineering plastics. PC granules need to be dried using a dryer during the production process.

[0003] However, existing dryers cause PC granules to clump together during drying, resulting in uneven heating inside and outside the granule pile. This leads to slow drying inside the pile and over-drying on the outside, ultimately affecting the quality of the formed PC granules. To address these issues, innovative designs based on existing PC granule dryers are urgently needed. Utility Model Content

[0004] The purpose of this invention is to provide a dryer that ensures uniform heating of PC particles, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dryer for uniformly heated PC particles, comprising a drying chamber, wherein the drying chamber is respectively provided with a feed pipe and an exhaust plate, the drying chamber is inclinedly provided with a perforated guide plate that can vibrate up and down, the feed pipe is provided with a cylindrical groove, and a cylindrical material picker driven to rotate by a driving device is provided inside the cylindrical groove, the cylindrical material picker is provided with a material picker groove.

[0006] Preferably, the feed pipe is equipped with a storage bin, the drying box is fixed with a collection box, and the lowest end of the perforated guide plate passes through the drying box and the collection box and is located inside the collection box.

[0007] Preferably, the perforated guide plate is equipped with a support frame, the support frame is provided with a movable rod, the movable rod passes through the drying box and is installed with a movable plate, the movable rod is nested with a spring, and the movable plate is provided with a vibration motor.

[0008] Preferably, the support frame includes a rectangular frame and an X-shaped frame, with the X-shaped frame fixed at equal intervals inside the rectangular frame.

[0009] Preferably, the cylindrical material handling component is fixedly connected to the motor through the feed pipe.

[0010] Preferably, the drying box is equipped with a dehumidification pipe, and the dehumidification pipe is equipped with a filter screen.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This PC particle uniformly heated dryer, by starting the vibration motor, can drive the perforated guide plate to vibrate up and down. At the same time, the small angle setting of the perforated guide plate of 1-3° extends the movement time of the PC particles on the perforated guide plate, so that the PC particles can fully contact the hot air and can also be heated evenly, thus improving the drying effect of the PC particles. Each rotation of the cylindrical feeding component allows the feeding trough to pick up material from the inside of the feeding pipe and send it to the inside of the drying box once, which can achieve intermittent discharge and avoid a large number of PC particles accumulating on the perforated guide plate at the same time, resulting in poor drying effect inside the PC particle pile.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5This utility model provides a technical solution: a dryer for uniformly heated PC particles, including a drying chamber 1. A support frame is provided at the bottom of the drying chamber 1 for supporting the entire dryer. A feed pipe 3 is fixedly connected to one end of the top of the drying chamber 1. An exhaust plate 15 is provided at the bottom of the drying chamber 1, with an inner cavity inside the exhaust plate 15. Air outlets are evenly distributed at the top of the exhaust plate 15, and the inner cavity and air outlets are interconnected. An air inlet pipe 16 is fixedly connected to one side of the exhaust plate 15, penetrating the side wall of the drying chamber 1. The end of the air inlet pipe 16 is connected to a hot air blower connected to the outside via a pipe. Through several air outlets, upward-moving hot air can be generated inside the drying chamber 1. A perforated guide plate 5, capable of vertical vibration, is inclinedly arranged inside the drying chamber 1. The perforated guide plate 5 has evenly distributed holes, the diameter of which is smaller than the diameter of the PC particles, preventing the PC particles from entering the drying chamber through the holes in the perforated guide plate 5. Below the perforated guide plate 5, the tilt angle of the perforated guide plate 5 is set at 1-3°, which prolongs the time that PC particles move on the perforated guide plate 5, thereby prolonging the contact time between the PC particles and the hot air and improving the drying effect of the PC particles. The inside of the feed pipe 3 is provided with a cylindrical groove 11, and the cylindrical groove 11 is provided with a cylindrical material picker 12 driven to rotate by a drive device. The length of the feed pipe 3 is equal to the width of the perforated guide plate 5, so that the PC particles discharged from the feed pipe 3 can be evenly sprinkled on the perforated guide plate 5, reducing the situation where PC particles pile up together. The top of the cylindrical material picker 12 is provided with a material picker trough 13. Every time the cylindrical material picker 12 rotates, the material picker trough 13 can pick up material from the inside of the feed pipe 3 and send it to the inside of the drying box 1 once, so as to achieve intermittent discharge and avoid a large number of PC particles accumulating on the perforated guide plate 5 at the same time, resulting in poor drying effect inside the PC particle pile.

[0020] The top of the feed pipe 3 is fixedly connected to the storage bin 2. One end of the drying box 1 is fixedly connected to the collection box 4 away from the feed pipe 3. The lowest end of the perforated guide plate 5 passes through the side wall of the drying box 1 and the collection box 4 and is located inside the collection box 4. The top of the storage bin 2 is fitted with a sealing top cover. The bottom outlet of the collection box 4 is fitted with a sealing bottom cover. The sealing bottom cover and the bottom outlet of the collection box 4 are fixedly connected by bolts.

[0021] A support frame 6 is fixed to the bottom of the perforated guide plate 5. A movable rod 7 is fixed to one side of the bottom of the support frame 6. The lower end of the movable rod 7 slides through the bottom of the drying box 1 and is fixed to a movable plate 8. The upper and lower sections of the movable rod 7 are respectively nested with springs 9 inside and outside the drying box 1. Vibration motors 10 are fixed at equal intervals at the bottom of the movable plate 8. By starting the vibration motor 10, in conjunction with the springs 9, the perforated guide plate 5 can be made to vibrate up and down, so that the PC particles on the perforated guide plate 5 can also vibrate up and down and fully contact the upward flowing hot air, which improves the drying quality of the PC particles. At the same time, it can make the PC particles move towards the lower part of the perforated guide plate 5 and the inside of the collection box 4, avoiding the situation where the PC particles cannot move due to the small tilt angle of the perforated guide plate 5.

[0022] The support frame 6 includes a rectangular frame and an X-shaped frame. The X-shaped frames are fixed at equal intervals inside the rectangular frame, which increases the overall strength of the support frame 6 and allows for reserved space inside the support frame 6 for hot air to pass through.

[0023] One end of the cylindrical material take-up piece 12 passes through the side of the feed pipe 3 and is fixedly connected to the output end of the motor 14. The motor 14 is fixed to the outside of the feed pipe 3 by bolts, which can drive the cylindrical material take-up piece 12 to rotate continuously at a uniform speed, so that the cylindrical material take-up piece 12 can discharge material intermittently.

[0024] The top of the drying oven is equipped with a dehumidification pipe, and the inside of the dehumidification pipe is equipped with a filter screen. The dehumidification pipe is used to discharge the moisture inside the drying oven 1, and the filter screen is used to isolate external impurities.

[0025] Working Principle: When using this PC granule evenly heated dryer, first start the vibration motor 10. The vibration motor 10 drives the perforated guide plate 5, support frame 6, movable rod 7, and movable plate 8 to vibrate up and down via the spring 9. Then start the motor 14, which is the driving device, driving the cylindrical material picker 12 and the material picker trough 13 to rotate. Each time the cylindrical material picker 12 rotates, the material picker trough 13 picks up material from inside the feed pipe 3 and sends it into the drying chamber 1 once, achieving intermittent discharge and avoiding continuous discharge from the feed pipe 3, which would cause PC granules to accumulate on the belt. The top of the perforated guide plate 5, under the vibration of the perforated guide plate 5 and with the perforated guide plate 5 tilted at an angle of 1-3°, allows the PC particles on the top of the perforated guide plate 5 to slowly move towards the collection box 4. At the same time, the external hot air fan is started, and the hot air generated by the hot air fan flows upward inside the drying box 1 through the exhaust plate 15 and the air inlet pipe 16, so that it can fully contact the PC particles vibrating up and down on the top of the perforated guide plate 5, so that the PC particles are heated evenly, improving the drying quality of the PC particles. The dried PC particles enter the collection box 4 for storage.
