Description

Technical Field

[0001] This utility model belongs to the field of polyester chip processing technology, specifically a drying device for modified polyester chips. Background Technology

[0002] Modified polyester chips refer to materials that optimize the performance of conventional polyester by changing the molecular chain structure through copolymerization or by adding functional additives to impart specific properties. They are widely used in textiles, packaging, engineering plastics and other fields. Polyester chips, on the other hand, usually refer to polyester raw materials obtained from polymerization that are processed into sheet-like granules.

[0003] After slicing, the polyester granules need to be dried to avoid residual moisture causing problems in subsequent processing. However, in traditional drying, a large number of polyester granules are filled at once, and the accumulation of these granules can lead to uneven drying and affect the drying effect. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a drying device for modified polyester chips, which solves the problem that when a large number of polyester particles are filled in at once during drying, the accumulation of these polyester particles will lead to uneven drying and affect the drying effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for modified polyester chips, comprising a drying tank, a hot air box fixedly installed on one side of the drying tank, a support frame connected to the drying tank, an end cap connected to the top of the drying tank, a discharge pipe connected to the bottom of the drying tank, multiple guide hoppers connected inside the drying tank, a packing pipe connected to the end cap, a working motor fixedly installed on the end cap, and multiple ventilation openings on the hot air box;

[0006] Heating tubes are installed inside the hot air box, and a drive motor is fixedly installed inside the hot air box. Fan blades are installed on the output shaft of the drive motor. A dustproof net is connected to the opening of the hot air box that extends into the drying tank. A second dustproof net is connected to the inner wall of the hot air box on the side near the vent. A rotating rod is connected to the output shaft of the working motor. A material distribution plate is connected to the rotating rod. A first material distribution plate and a second material distribution plate are connected to the rotating rod. Multiple stirring plates are connected to one end of the rotating rod.

[0007] As a further embodiment of this utility model: a base plate is connected below the support frame, and an anti-slip pad is connected below the base plate.

[0008] As a further embodiment of this utility model: a control valve is installed on the discharge pipe, a cap is inserted into the packing pipe, and the connection between the drying tank and the discharge pipe is a hemispherical design.

[0009] As a further embodiment of this utility model: the first and second material distribution plates are inclined to each other to form a V-shaped structure, and the three guide hoppers are arranged at equal intervals in the drying tank, and the three guide hoppers are respectively located below the material distribution plate, the first material distribution plate and the second material distribution plate.

[0010] As a further embodiment of this utility model: the rotating rod is rotatably connected to the end cover via a bearing, and the end cover has multiple air outlets symmetrically arranged around the center, with a dustproof ring connected to the end cover at the position of the air outlet.

[0011] As a further embodiment of this utility model: the bulk material tray is spindle-shaped, and multiple partition plates are connected at equal intervals on the top of the bulk material tray in a centrally symmetrical manner.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This drying device for modified polyester chips is equipped with a drive motor, fan blades, heating tubes, a working motor, a rotating rod, a material distribution plate, a first material distribution plate, and a second material distribution plate. During operation, the heating tubes heat the air inside the hot air box, while the drive motor rotates the fan blades to blow hot air into the drying tank, thereby raising the internal temperature of the drying tank. The working motor rotates the rotating rod, and the polyester granules that are filled in first fall onto the material distribution plate. The rotating material distribution plate and the partition plate disperse the accumulated granules, and the guide hopper guides the dispersed granules to fall onto the first and second material distribution plates in stages, thereby dispersing them multiple times, preventing accumulation, slowing down the falling speed, promoting uniform heating of the granules, and improving the drying effect.

[0014] 2. This drying device for modified polyester chips, by setting up a stirring plate, dustproof net one, dustproof net two, and ventilation openings, causes the stirring plate to rotate along with the rotating rod of the working motor. This continuously stirs the polyester particles at the bottom of the drying tank, preventing them from piling up and ensuring their flow. This prevents the polyester particles from clogging the bottom of the drying tank and affecting the discharge. When the fan blades rotate, dustproof net one and dustproof net two can block dust, preventing dust from entering the hot air box and drying tank through the ventilation openings, thus preventing dust from contaminating the polyester particles.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a drying device for modified polyester chips, including a drying tank 1, a hot air box 2 fixedly installed on one side of the drying tank 1, a support frame 3 connected to the drying tank 1, a base plate 20 connected below the support frame 3, and an anti-slip pad 21 connected below the base plate 20. The anti-slip pad 21 below the base plate 20 increases the friction between the base plate 20 and the ground, preventing slippage and thus improving the stability of the working placement.

[0022] The top of the drying tank 1 is connected to an end cap 4, and the bottom of the drying tank 1 is connected to a discharge pipe 5. A control valve 22 is installed on the discharge pipe 5, and a cap 23 is inserted into the packing pipe 7. The connection between the drying tank 1 and the discharge pipe 5 is a hemispherical design. Through the hemispherical design at the bottom of the drying tank 1, the polyester particles can flow along the arc-shaped inner wall to the discharge pipe 5, thus facilitating discharge.

[0023] The drying tank 1 is internally connected to multiple feed hoppers 6. The end cover 4 is connected to a packing tube 7. A working motor 8 is fixedly installed on the end cover 4. The hot air box 2 has multiple vents 9. A heating tube 10 is installed inside the hot air box 2. A drive motor 11 is fixedly installed inside the hot air box 2. A fan blade 12 is installed on the output shaft of the drive motor 11. A dustproof net 13 is connected to the opening of the hot air box 2 that extends into the drying tank 1. A second dustproof net 14 is connected to the inner wall of the hot air box 2 near the vent 9. A rotating rod 15 is connected to the output shaft of the working motor 8. The rotating rod 15 is rotatably connected to the end cover 4 through a bearing. Multiple air outlets 24 are symmetrically arranged on the end cover 4. A dustproof ring 25 is connected to the end cover 4 at the position of the air outlet 24. The multiple air outlets 24 on the end cover 4 can ensure normal air circulation inside the drying tank 1, while the dustproof ring 25 can block dust and prevent dust from entering the drying tank 1 from the air outlets 24.

[0024] A material distribution plate 16 is connected to the rotating rod 15. The material distribution plate 16 is spindle-shaped. Multiple partition plates 26 are connected at equal intervals in a centrally symmetrical manner above the material distribution plate 16. The slightly inclined spindle-shaped surface of the material distribution plate 16 allows polyester particles to slide off the rotating material distribution plate 16 easily. When the material distribution plate 16 rotates, the partition plates 26 can carry some of the falling particles, so that the particles rotate with the material distribution plate 16 and are evenly distributed, avoiding the particles from falling to one side.

[0025] The rotating rod 15 is connected to a first material distribution plate 17 and a second material distribution plate 18. One end of the rotating rod 15 is connected to multiple stirring plates 19. The first material distribution plate 17 and the second material distribution plate 18 are inclined to each other to form a V-shaped structure. Three guide hoppers 6 are arranged at equal intervals in the drying tank 1. The three guide hoppers 6 are respectively set below the material distribution plate 16, the first material distribution plate 17 and the second material distribution plate 18. The guide hoppers 6 can stably slide the scattered polyester particles onto the first material distribution plate 17 and the second material distribution plate 18. When the inclined first material distribution plate 17 and the second material distribution plate 18 rotate, the particles can slide evenly and avoid being concentrated on one side. The guide hoppers 6, the first material distribution plate 17 and the second material distribution plate 18 extend the particle falling time, thereby increasing the heating time.

[0026] The working principle of this utility model is as follows:

[0027] During operation, the heating tube 10 heats the air inside the hot air box 2, while the drive motor 11 rotates the fan blades 12, causing the fan blades 12 to blow hot air into the drying tank 1, raising the internal temperature of the drying tank 1. The working motor 8 is then activated to rotate the rotating rod 15, causing the material distribution plate 16, the first material distribution plate 17, and the second material distribution plate 18 to rotate. The polyester granules filled by the packing tube 7 will first fall onto the material distribution plate 16. The rotating material distribution plate 16 and the partition plate 26 disperse the accumulated granules, scattering them. The guide hopper 6 then guides the dispersed granules to fall onto the first material distribution plate 17 and the second material distribution plate 18 in stages, thus dispersing them multiple times and preventing accumulation. The stirring plate 19 rotates together with the rotating rod 15, continuously stirring the polyester granules at the bottom of the drying tank 1 to prevent them from accumulating and to ensure the flow of the polyester granules for easy discharge.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
