Description

Technical Field

[0001] This utility model relates to the field of granule drying technology, specifically a highly efficient plastic granule drying device. Background Technology

[0002] During the production process, plastic granules typically absorb a large amount of moisture due to cooling methods (such as water cooling). Excessive moisture content can affect their melting temperature, melt flowability, and bubble formation, thus impacting molding quality and production efficiency. Therefore, drying plastic granules is a crucial process in plastic processing. Uneven heating is a major concern: traditional drying equipment typically uses hot air, but this only dries the surface of the granules, leaving the internal particles undried. Furthermore, plastic granules tend to accumulate during drying, leading to uneven heating and low drying efficiency. Some existing drying devices use a rotating drying drum to centrifuge the plastic while drying, but the poor uniformity of the granules results in low drying efficiency and high energy consumption. Some drying devices employ a fully integrated heating system, increasing operating costs. Granule adhesion is another issue: during drying, some plastic granules tend to stick together, affecting product quality. Adding stirring and dispersing mechanisms: by incorporating stirring blades, spiral drive blades, and other devices, the plastic granules can be fully tumbled and dispersed during drying, improving heating uniformity. Optimized hot air circulation system: Employing vibrating fluidized bed technology ensures uniform contact between hot air and plastic granules, improving drying efficiency. Waste heat recovery: Recovering waste heat generated during the drying process reduces energy consumption. Prevention of granule sticking: Adding a crushing mechanism to the drying unit or using special drying methods prevents plastic granules from sticking together during the drying process. These improvements provide a technological foundation for developing more efficient and energy-saving plastic granule drying equipment. Utility Model Content

[0018] like Figures 1 to 4 As shown, this embodiment provides a highly efficient plastic granule drying device, including: a support 1; a material holding assembly, including a material holding bucket 303 arranged on the support 1 for holding plastic granules, and an outer wall assembly; and a hot air assembly, including an air outlet 403 arranged on the support 1 for spraying drying air to dry the plastic granules.

[0019] In this embodiment, the material holding assembly and the hot air assembly constitute a highly efficient plastic pellet drying device according to this application.

[0020] It should also be understood that a hot air blower is a device that converts electrical energy or other energy into heat energy and transfers the heat out through airflow. Since it is only used and not modified, the control method and circuit connection will not be described in detail.

[0021] Specifically, the material holding assembly includes: a main shaft 304, fixedly arranged inside the material holding hopper 303, for rotating the material holding hopper 303; an outer shaft 305, sleeved on the main shaft 304, with one end fixed to the main shaft 304 with a nut; a motor 309, mounted on the bracket 1, for rotating the main shaft 304, with one end of the main shaft 304 fixedly arranged at the output end of the motor 309; a stop door 307, hingedly connected to one side of the material holding hopper 303, for opening and placing plastic granules; and a spring pin 308, arranged on the stop door 307, for locking the stop door 307.

[0022] In this embodiment, the main shaft 304 passes through the center of the material container 303; the outer shaft 305 is made of seamless steel pipe, is sleeved on the main shaft 304, and is fixed with a nut; the spring pin 308 is made of stainless steel and is arranged on the left side of the baffle 307; the motor 309 drives the main shaft 304 and the material container 303 to rotate, and the baffle 307 is locked by the spring pin 308, so that the plastic particles tumble inside the container, improving the drying uniformity.

[0023] Specifically, the material container 303 is made of mesh and is cylindrical in shape.

[0024] As a preferred implementation method, the material container 303 has a mesh structure that allows hot air to penetrate the material layer, and its cylindrical design facilitates uniform rotation, improves drying efficiency, and avoids particle accumulation. Example

[0025] Based on Example 1, in order to further improve drying efficiency, an outer wall assembly is arranged around the material container 303; Specifically, the material holding assembly also includes an outer wall assembly: a housing 301, mounted on the bracket 1, for mounting the material holding assembly, with the main shaft 304 rotatably connected to the housing 301; an air outlet 311, located above the housing 301, for venting; a limiting wheel 306, rotatably connected to the inner wall of the housing 301, with the outer side of the material holding bucket 303 abutting against the limiting wheel 306; a lid 302, connected to one side of the housing 301 by a hinge, for opening the housing 301; and a spring pin 310, located on the lid 302, for locking the lid 302.

[0026] In this embodiment, the box body 301 is sealed and insulated, the limiting wheel 306 supports the material container 303 and reduces rotational friction, the box cover 302 is locked by the spring pin 310, and the vent 311 discharges hot and humid air.

[0027] Specifically, the limit wheels 306 are provided in two sets, with four in each set evenly distributed inside the housing 301.

[0028] With this configuration, there are two sets of limit wheels 306, with four in each set, which are arranged on the upper and lower edges of the inner wall of the box 301, evenly distributed at 90° intervals. The two sets of limit wheels 306 support the material container 303, ensuring its coaxiality during rotation, preventing shaking, and extending the service life of the equipment. Example

[0029] Based on Example 2, in order to synchronously drive the turning device and the drying operation, a hot air assembly is arranged on the support 1. Specifically, the hot air assembly includes: an air duct 402, which is installed inside the housing 301, and an air outlet 403 is installed on the air duct 402 for conveying hot air; and a hot air blower 401, whose air outlet is fixed to one end of the air duct 402 for generating drying air.

[0030] The exhaust duct 402 is made of stainless steel and is located at the bottom of the housing 301. The air outlet 403 is made of stainless steel and is evenly distributed on the exhaust duct 402. The hot air blower 401 is installed on the left side of the bracket 1. The hot air blower 401 generates hot air that is sprayed out from the air outlet 403 through the exhaust duct 402, penetrates the mesh structure of the material container 303 to dry the plastic granules, and the hot air is recycled to improve efficiency.

[0031] Specifically, the 402 exhaust duct is made of high-quality steel.

[0032] In this embodiment, the 402 stainless steel exhaust pipe is resistant to high temperature and corrosion, ensuring that it does not deform or rust during hot air delivery, maintaining a stable drying temperature, and extending the service life of the equipment.

[0033] In actual use, the operator first opens the box cover 302, then opens the stop door 307, and pours the plastic granules into the material container 303. Then, the stop door 307 and the box cover 302 are locked in sequence by spring pin one 308 and spring pin two 310. The motor 309 and the hot air blower 401 are started. Under the rotation of the motor 309, the material container 303 is driven to rotate. The material container 303 rotates between the limit wheels 306, and the limit wheels 306 support and limit the material container 303. At this time, the drying air generated by the hot air blower 401 enters the air duct 402 and is discharged through the air outlet 403. Inside the box 301, as the material container 303 rotates, the plastic granules will come into even contact with the drying air discharged from the air outlet 403 and be dried. Because the drying air is continuously supplied, the air outlet 311 should be opened to discharge the hot air. When the drying time is up, the motor 309 and the hot air blower 401 should be stopped immediately, and the hot air should be completely discharged. Then, the box cover 302 and the baffle door 307 should be opened in sequence to take out the plastic granules. Repeat the operation to dry the plastic granules efficiently.

[0034] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
