Description

Technical Field

[0001] The utility model relates to the technical field of polyester chip production and drying, in particular to a polyester chip low-temperature drying device. Background Art

[0002] Polyester is a commonly used synthetic material widely used in textiles, packaging, electronics, and other fields. During the polyester production process, a large amount of polyester fragments is generated. If these polyester fragments are not effectively utilized, they not only waste resources but also pollute the environment. Therefore, recycling polyester fragments is of great significance.

[0003] Before polyester flakes can be further processed, they need to be dried to remove surface moisture. Traditional drying methods for polyester flakes include hot air drying and natural air drying. While hot air drying is fast, it consumes a lot of energy and can easily cause deformation of the polyester flakes. Natural air drying, while cost-effective, is highly affected by weather, takes a long time to dry, and is inefficient.

[0004] To address these issues, some low-temperature drying devices have emerged. Existing low-temperature drying devices for polyester chips primarily utilize a vibration conveying method, exposing the polyester chips to low-temperature gas during the vibration process to achieve the drying purpose. However, existing devices have the following shortcomings:

[0005] The feeding method is single, and polyester fragments are easy to gather during the conveying process, resulting in uneven drying.

[0006] The contact area between polyester chips and low-temperature gas is small, and the drying efficiency is low.

[0007] The temperature adjustment range of cryogenic gas is limited and cannot be optimized according to the characteristics of polyester chips.

[0008] Due to the lack of automated collection devices, the dried polyester fragments need to be collected manually, which is inefficient. Utility Model Content

[0015] A diversion and guide interlayer plate distributed in the center of the linear feeding pipe;

[0016] A feed hopper installed on the top left end of the linear feed pipe;

[0024] Preferably, the upward tilt angle of the guide block surface from left to right is set to 4°, and a plurality of guide blocks are distributed in a stepped manner from left to right.

[0025] Preferably, a diversion baffle is provided inside the feed hopper, and the bottom end of the diversion baffle is bent to the right and connected to the leftmost end of the diversion guide barrier plate.

[0026] Preferably, a plurality of air outlet holes are provided at the left end of the vibration chassis, and the plurality of air outlet holes are communicated with the interior of the left end of the linear feeding pipe.

[0027] Preferably, a guide plate is provided at the right end of the vibration chassis, the right end of the guide plate is located directly below the discharge port, and the left end of the guide plate extends to the center position of the bottom of the vibration chassis.

[0028] Preferably, a discharge bin is installed at the bottom center of the vibration chassis.

[0029] Preferably, a vibration motor is installed at the center of the front wall of the vibration chassis.

[0030] Compared with the prior art, the present invention provides a low-temperature drying device for polyester chips, which has the following beneficial effects:

[0031] The polyester chip low-temperature drying device adopts a unique feeding component design. The polyester chips are evenly divided into two layers, upper and lower, through the diversion and guide partition plate inside the linear feeding pipe, which increases the contact area between the polyester chips and the low-temperature drying gas and improves the drying efficiency.

[0032] The guide blocks in the feeding assembly are distributed in a stepped manner, with a surface inclination angle of 4°. They can continuously guide the polyester chips to the right during the vibration process, so that the polyester chips can be fully turned over when moving inside the linear feeding pipe, further increasing the contact area with the low-temperature drying gas.

[0033] The low-temperature air supply mechanism uses a refrigerator to produce low-temperature drying gas. The temperature can be adjusted according to the characteristics of the polyester chips and is generally controlled between -10℃ and 10℃, ensuring the optimal temperature range for the drying process.

[0034] The low-temperature drying gas is evenly fed into the right end of the linear feeding pipe through the air inlet hood and the air inlet hole. It flows from right to left inside the pipe, forming reverse contact with the polyester chips that gradually move to the right, fully removing the moisture on the surface of the polyester chips to achieve efficient drying.

[0035] The vibration motor drives the vibration box to vibrate, so that the polyester chips can be fully turned over when moving inside the linear feeding pipe, further improving the drying efficiency.

[0036] The dried polyester chips are automatically guided to the discharge bin at the bottom of the vibration chassis through the guide plate, realizing automatic collection and reducing manual operation.

[0037] In summary, this polyester chip low-temperature drying device utilizes a unique feed assembly design to evenly divide the polyester chips into two layers, one above the other. The stepped guide blocks ensure that the chips are fully agitated during vibration, increasing their contact area with the low-temperature drying gas. Furthermore, the low-temperature drying gas generated by the low-temperature air supply mechanism creates counter-contact with the polyester chips, fully removing moisture from their surface. The vibration of the vibration motor further enhances drying efficiency. The entire device is automated, reducing manual intervention and improving production efficiency.

[0052] The feeding assembly 3 specifically includes the following structures: a straight feeding pipe 31 installed inside the vibration chassis 1 and tilted upward from left to right, and the overall tilt angle from left to right is set to 2°; a diverter guide partition plate 33 distributed in the center of the straight feeding pipe 31, the diverter guide partition plate 33 divides the internal space of the straight feeding pipe 31 into two layers, increasing the contact area between the polyester fragments and the low-temperature gas; a feed hopper 32 installed at the top of the left end of the straight feeding pipe 31, used to introduce the polyester fragments into the straight feeding pipe 31, and a diverter partition 321 is provided inside the feed hopper 32, and the bottom end of the diverter partition 321 is bent to the right. It is connected to the leftmost end of the diverter and guide partition plate 33, so that the polyester chips in the feed hopper 32 are evenly divided into two parts, upper and lower parts, and enter the linear feeding pipe 31; a discharge port 34 is distributed at the bottom of the right end of the linear feeding pipe 31, and the discharge port 34 is used to discharge the dried polyester chips; a number of guide blocks 35 are evenly distributed from left to right on the diverter and guide partition plate 33 and the bottom tube surface of the linear feeding pipe 31, and the surfaces are inclined to the upper right. The angle of the upward inclination of the surface from left to right is set to 4°, and the several guide blocks 35 are distributed in an inclined stepped manner from left to right. The guide blocks 35 can continuously guide the polyester chips to the right during the vibration process.

[0053] The low-temperature air supply mechanism 4 specifically includes the following structures: a refrigerator 41 distributed on the right side of the outside of the vibration chassis 1, and the refrigerator 41 is used to produce low-temperature dry gas; an air pump 42 connected to the output end of the refrigerator 41, and the air pump 42 is used to extract the low-temperature gas produced by the refrigerator 41; an air inlet hood 43 connected to the air outlet end of the air pump 42, and the outer end face of the air inlet hood 43 is installed on the right end face of the vibration chassis 1 and is connected to the interior of the linear feeding pipe 31 through several air inlet holes 11 on its end face. The air inlet hood 43 is used to evenly introduce the low-temperature gas into the interior of the linear feeding pipe 31.

[0054] The left end of the vibration chassis 1 is provided with a plurality of air outlets 12, which are connected to the interior of the left end of the linear feed pipe 31 and are used to exhaust the air inside the linear feed pipe 31.

[0055] How it works

[0056] Polyester flakes enter the linear feed pipe 31 from the feed hopper 32. Diverter baffles 321 and diverter guide plates 33 work together to evenly separate the flakes into two layers. A vibration motor 15 drives the vibrating housing 1, which in turn slowly guides the polyester flakes from left to right along the stepped guide blocks 35 along the linear feed pipe 31. Simultaneously, a refrigerator 41 produces low-temperature dry air. The temperature of the low-temperature dry air can be adjusted based on the characteristics of the polyester flakes, typically between -10°C and 10°C. An air pump 42 extracts the low-temperature dry air and evenly distributes it into the right end of the linear feed pipe 31 through an air inlet hood 43 and air inlet port 11. The low-temperature dry air flows from right to left within the linear feed pipe 31, making full contact with the polyester flakes as they gradually move rightward, removing moisture from their surfaces. The moist, hot air is then discharged through the air outlet port 12. The vibration motor 15 causes the polyester flakes to be fully agitated, increasing their contact area with the low-temperature dry air and improving drying efficiency. The dried polyester chips fall from the discharge port 34 onto the guide plate 13 , slide along the guide plate 13 to the bottom of the vibration chassis 1 , and finally enter the discharge bin 14 , completing the entire drying process.
