Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic granule processing technology, specifically to an integrated equipment for drying and dehumidifying plastic granules. Background Technology
[0002] In the production of plastic products, the drying and dehumidification of plastic granules is a crucial step. Plastic granules often absorb moisture from the air during storage and transportation. If this moisture is not effectively removed, it can cause numerous problems in subsequent processing. For example, during injection molding, moisture may cause air bubbles in the molten plastic, affecting the appearance and mechanical properties of the product; in extrusion molding, moisture may cause unstable flow of the molten plastic, resulting in dimensional deviations and surface defects. Therefore, drying plastic granules is a key step in ensuring the quality of plastic products.
[0003] Traditional drying equipment often suffers from uneven drying when processing large quantities of plastic granules. Because plastic granules tend to accumulate during the drying process, some granules are exposed to the heat source for too long and become overheated, while others are under-exposed and not thoroughly dried.
[0004] Therefore, an integrated equipment for drying and dehumidifying plastic granules is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide an integrated device for drying and dehumidifying plastic granules in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] An integrated plastic granule drying and dehumidification device includes a housing, a mounting shell fixedly connected to the top surface of the housing, a feeding hopper fixedly inserted into the top surface of the mounting shell, a feeding distribution component installed in the middle of the mounting shell, an air blowing dehumidification component arranged in the middle of the housing, a heating rod fixedly installed at the bottom of the inner wall of the housing, an agitation component installed at the bottom of the housing, discharge valves fixedly installed on both the left and right sides of the bottom surface of the housing, and a circulation component arranged on the left side of the housing.
[0008] Furthermore, the feeding distribution assembly includes an electric push rod, which is fixedly installed in the middle of the top surface of the mounting housing, and a limiting frustum is fixedly connected to the telescopic end of the electric push rod.
[0009] Furthermore, the air blowing dehumidification component includes a fan, which is fixedly installed on the front of the housing. An air inlet pipe is fixedly connected to the air outlet of the fan, and an annular pipe is fixedly connected to the end of the air inlet pipe. A nozzle is fixedly installed on the surface of the annular pipe, and a ventilation hole is opened through the surface of the housing.
[0010] Furthermore, the agitation assembly includes a first motor, which is fixedly installed in the middle of the bottom surface of the housing. The output end of the first motor is fixedly connected to a first rotating shaft, and the end of the first rotating shaft is fixedly connected to a scraper.
[0011] Furthermore, the circulation component includes a fixed cylinder, which is fixedly connected to the housing and to the bottom end of the discharge valve on the left side. A second motor is fixedly installed on the top surface of the fixed cylinder, and a second rotating shaft is fixedly connected to the output end of the second motor. Spiral blades are fixedly connected to the surface of the second rotating shaft. A guide pipe is fixedly inserted into the surface of the fixed cylinder and is fixedly connected to the mounting shell.
[0012] Furthermore, the bottom of the housing is fixedly connected to four support legs in a circular array, and the bottom of each support leg is fixedly connected to a rubber pad.
[0013] The beneficial effects of this utility model are as follows:
[0014] Plastic granules are added to the interior of the mounting shell using a feeding hopper. The granules are then evenly distributed into the shell via a feeding distribution component. An air-blowing dehumidification component blows air through the falling granules, achieving initial dehumidification. A heating rod then heats and dries the granules. A stirring component agitates the granules, ensuring more even drying. The discharge valve on the left opens, allowing the granules to enter the circulation component, which guides them back into the mounting shell. This process repeats until all granules are dry. Finally, the discharge valve on the right discharges the granules. This invention achieves rapid dehumidification and drying of plastic granules, resulting in more uniform drying compared to existing technologies and avoiding the problem of uneven drying caused by accumulated granules.

[0025] like Figures 1 to 4As shown, an integrated plastic granule drying and dehumidification device includes a housing 1, a mounting shell 2 fixedly connected to the top surface of the housing 1, a feeding hopper 4 fixedly inserted into the top surface of the mounting shell 2, and a feeding distribution assembly 3 installed in the middle of the mounting shell 2. The feeding distribution assembly 3 includes an electric push rod 301, which is fixedly installed in the middle of the top surface of the mounting shell 2. The telescopic end of the electric push rod 301 is fixedly connected to a limiting frustum 302. It should be noted that the plastic granules entering the mounting shell 2 can flow downwards evenly through the gap between the bottom of the mounting shell 2 and the limiting frustum 302, facilitating the subsequent dehumidification by the air blowing dehumidification assembly 5. The operation of the electric push rod 301 can drive the limiting frustum 302 to move vertically, thereby adjusting the gap between the limiting frustum 302 and the bottom of the mounting shell 2, which can easily accommodate plastic granules of different specifications.
[0026] An air-blowing dehumidification assembly 5 is located in the middle of the casing 1. The air-blowing dehumidification assembly 5 includes a fan 501, which is fixedly installed on the front of the casing 1. An air inlet pipe 502 is fixedly connected to the air outlet of the fan 501, and an annular pipe 503 is fixedly connected to the end of the air inlet pipe 502. A nozzle 504 is fixedly installed on the surface of the annular pipe 503, and a ventilation hole 505 is opened through the surface of the casing 1. More specifically, by operating the fan 501, air is introduced into the annular pipe 503 through the air inlet pipe 502, and then sprayed out through the nozzle 504 to form an airflow. The ventilation hole 505 ensures gas exchange, allowing water vapor on the surface of the plastic particles to be discharged, while fresh air is introduced, forming a good airflow circulation and accelerating the drying process.
[0027] A heating rod 6 is fixedly installed on the bottom inner wall of the casing 1. An agitation assembly 8 is installed on the bottom of the casing 1. The agitation assembly 8 includes a first motor 801, which is fixedly installed in the middle of the bottom surface of the casing 1. A first rotating shaft 802 is fixedly connected to the output end of the first motor 801, and a scraper 803 is fixedly connected to the end of the first rotating shaft 802. It should be noted that the operation of the first motor 801 drives the first rotating shaft 802 to rotate, thereby driving the scraper 803 to rotate. The scraper 803 agitates the plastic granules inside the casing 1, so that the plastic granules are evenly heated and dried by the heating rod 6. At the same time, the scraper 803 also helps the plastic granules to smoothly enter the discharge valve 7.
[0028] Discharge valves 7 are fixedly installed on both the left and right sides of the bottom surface of the casing 1. A circulation assembly 9 is provided on the left side of the casing 1. The circulation assembly 9 includes a fixed cylinder 901, which is fixedly connected to the casing 1 and to the bottom end of the left discharge valve 7. A second motor 902 is fixedly installed on the top surface of the fixed cylinder 901. A second rotating shaft 903 is fixedly connected to the output end of the second motor 902. Spiral blades 904 are fixedly connected to the surface of the second rotating shaft 903. A guide pipe 905 is fixedly inserted into the surface of the fixed cylinder 901 and is fixedly connected to the mounting shell 2. More specifically, by opening the left discharge valve 7, plastic granules can enter the interior of the fixed cylinder 901. The second motor 902 drives the second rotating shaft 903 to rotate, thereby lifting the plastic granules and guiding them back into the mounting shell 2 through the guide pipe 905.
[0029] The bottom of the casing 1 is fixedly connected to four support legs in a circular array, and rubber pads are fixedly connected to the bottom of the support legs. It should be noted that by setting up support legs and rubber pads, the equipment is stably supported and the vibration generated during operation is absorbed.
[0030] In summary: The plastic granules are fed into the housing 2 using the feeding hopper 4. The feeding distribution component 3 evenly distributes the granules into the housing 1. The air blowing dehumidification component 5 blows air onto the falling granules, achieving initial dehumidification. The heating rod 6 then heats and dries the granules. The stirring component 8 agitates the granules, ensuring more even heating and drying. The discharge valve 7 on the left opens, allowing the granules to enter the circulation component 9, which guides them back into the housing 2. The above steps are repeated for dehumidification and drying. After processing, the granules are discharged through the discharge valve 7 on the right. This invention achieves rapid dehumidification and drying of plastic granules, resulting in more uniform drying compared to existing technologies and avoiding the problem of uneven drying due to accumulating granules.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
