Description

Technical Field

[0001] This utility model relates to the field of ABS plastic granule production technology, and in particular to a drying device for ABS plastic granule production. Background Technology

[0002] ABS (an abbreviation for Acrylonitrile Butadiene Styrene) is a high-strength, tough, and easily processed thermoplastic polymer material; it is a slightly yellow solid with a certain degree of toughness and a density of approximately 1.04–1.06 g / cm³. It has strong resistance to corrosion from acids, alkalis, and salts, and can also withstand dissolution by organic solvents to a certain extent.

[0003] Traditional ABS plastic granule drying equipment mostly uses hot air blowers to dry the granules. The granules are piled up together, and the space between each granule is relatively small. The hot air blower not only takes a long time to dry the granules, but also results in insufficient drying, leading to poor drying efficiency and quality. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a drying device for the production of ABS plastic granules, thereby solving the problems mentioned in the background section.

[0005] A drying device for producing ABS plastic granules includes a drying chamber supported by a bracket, a drive mechanism and a drying mechanism mounted on the drying chamber. The drive mechanism includes a motor, a first transmission wheel, a synchronous belt, a second transmission wheel, and a disturbance part. The disturbance part is rotatably mounted inside the drying chamber. The second transmission wheel is fixedly mounted at one end of the disturbance part extending outside the drying chamber. The first transmission wheel is mounted at the output end of the motor and is connected to the second transmission wheel via the synchronous belt.

[0006] The drying mechanism includes an air duct, a connecting port, an air outlet, a partition plate, a mesh plate, and a guide plate. The air duct is installed on the outer wall of the drying chamber. Multiple air outlets and mesh plates are installed on the inner wall of the drying chamber, and the air outlets are connected to the air ducts. The connecting port is connected to the air ducts. The partition plate is located between the disturbance part and the mesh plate. The guide plate is installed at the bottom of the inner wall of the drying chamber and is corresponding to the lower guide port of the partition plate.

[0007] The bottom of the drying chamber is also equipped with a material blocking assembly, including an electric cylinder and a baffle. The baffle is slidably disposed at the material discharge port, and the output end of the electric cylinder is fixedly connected to the baffle.

[0008] The portion of the disturbance part located inside the drying chamber is arranged in the form of a frustum, and a disturbance plate is integrally arranged around its periphery. The other two sides of the disturbance plate are respectively attached to and slidably arranged with the inner wall of the drying chamber and the partition plate.

[0009] By adopting the above technical solution, the particles can be dispersed during drying, and the time for the particles to fall can be increased, allowing them to come into contact with the hot airflow for a longer period of time, thereby accelerating the drying efficiency of the particles.

[0010] The mesh panels are arranged in multiple sets, staggered from top to bottom, and there are also multiple air outlets, one of which is located above the disturbance part, and the rest are distributed on the mesh panels near the lower part of the drying chamber.

[0011] By adopting the above technical solution, the time for particles to fall is increased.

[0012] The upper surface of the guide plate is inclined toward the lower feed port, and the discharge port is located below the disturbance part.

[0013] By adopting the above technical solution, the particles can slide down to the area below the disturbance part.

[0014] The side of the drying chamber away from the motor is made of tempered glass, and a fastener is attached to the drying chamber.

[0015] By adopting the above technical solution, it is convenient to observe the drying process, so that the granules can be placed into the drying chamber.

[0016] The beneficial effects of the drying device for ABS plastic granule production of this utility model are:

[0017] This device can guide the particles through multiple sets of mesh plates during the drying process, dispersing the particles inside the drying chamber for uniform drying and increasing the time the particles fall, allowing them to be in contact with the hot airflow for a longer period of time, thus accelerating the drying effect of the hot airflow on the particles.

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0024] Reference Figure 1-4 A drying device for producing ABS plastic granules includes a drying chamber 1 supported by a bracket, and a drive mechanism and a drying mechanism installed on the drying chamber 1. The drive mechanism includes a motor 2, a first transmission wheel 3, a synchronous belt 4, a second transmission wheel 5, and a disturbance part 6. The disturbance part 6 is rotatably installed inside the drying chamber 1. The second transmission wheel 5 is fixedly installed at one end of the disturbance part 6 extending outside the drying chamber 1. The first transmission wheel 3 is installed at the output end of the motor 2 and is connected to the second transmission wheel 5 through the synchronous belt 4.

[0025] The drying mechanism includes an air duct 7, a connecting port 8, an air outlet 12, a partition plate 13, a mesh plate 14, and a guide plate 15. The air duct 7 is installed on the outer wall of the drying chamber 1. Multiple air outlets 12 and mesh plates 14 are installed on the inner wall of the drying chamber 1, and the air outlets 12 are connected to the air duct 7. The connecting port 8 is connected to the air duct 7. The partition plate 13 is located between the disturbance part 6 and the mesh plate 14. The guide plate 15 is installed at the bottom of the inner wall of the drying chamber 1 and is correspondingly arranged with the lower guide port 1302 of the partition plate 13.

[0026] A material blocking assembly is also provided at the material discharge port 101 at the bottom of the drying chamber 1, including an electric cylinder 9 and a baffle 10. The baffle 10 is slidably disposed at the material discharge port 101, and the output end of the electric cylinder 9 is fixedly connected to the baffle 10.

[0027] Remove the retaining plate 11 from the drying chamber 1, place the particles into the drying chamber 1 from this position, and start the external hot air blower to input hot air into the air passage 7 through the connection port 8. The hot air then enters the drying chamber 1 through the air passage 7 and out through the air outlet 12. The drive motor 2 drives the transmission wheel 3, which drives the transmission wheel 5 through the synchronous belt 4. The transmission wheel 5 drives the agitator 6 to rotate inside the drying chamber 1. The part of the agitator 6 inside the drying chamber 1 is truncated cone-shaped, and its periphery is integrally equipped with agitator plates 601. The other two sides of the agitator plates 601 are respectively attached to and slidably disposed against the inner wall of the drying chamber 1 and the partition plate 13. As the agitator 6 rotates, it scrapes the particles through the agitator plates 601 on its periphery. The particles are gradually lifted to the top. Once the particles reach the upper feed port 1301, they can fall from the upper feed port 1301 onto the screen plate 14. There are multiple sets of screen plates 14, which are staggered and inclined from top to bottom. There are also multiple air outlets 12, one of which is located above the disturbance part 6, and the rest are distributed at the lower position of the screen plate 14 near the inside of the drying chamber 1. By guiding the particles through multiple sets of screen plates 14, the particles are dispersed inside the drying chamber 1, while the time for the particles to fall is increased, so that the hot airflow can accelerate the drying effect on the particles. When the particles fall to the bottom of the drying chamber 1, they can be guided by the guide plate 15 to slide down below the disturbance part 6. Then, they continue to be lifted upward by the disturbance part 6 and dispersed for drying.

[0028] After drying is complete, the electric cylinder 9 can be driven to pull the baffle 10, opening the material discharge port 101 at the bottom of the drying chamber 1. The material can then fall out of the drying chamber 1 from the material discharge port 101 for collection.

[0029] This device can disperse the particles during the drying process and increase the time the particles fall, allowing them to be exposed to the hot airflow for a longer period of time, thereby accelerating the drying efficiency of the particles.

[0030] The upper surface of the guide plate 15 is inclined toward the lower feed port 1302, and the discharge port 101 is set below the disturbance part 6 to facilitate the particles to slide down to the bottom of the disturbance part 6.

[0031] The side of the drying chamber 1 away from the motor 2 is made of tempered glass, and a buckle plate 11 is attached to the drying chamber 1 for easy observation of the particles. The detachable buckle plate 11 makes it easy to put the particles into the drying chamber 1. During the drying process, the buckle plate 11 can also be opened to check the drying status of the particles.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
