Description

Technical Field

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

[0002] Plastic pellets are plastic raw materials that exist in granular form. They are classified into three categories according to their properties: general-purpose plastics, engineering plastics, and specialty plastics. General-purpose plastics include common types such as polypropylene and polyethylene.

[0003] Conventional methods for drying plastic granules typically involve placing them directly into a drying chamber for drying operations, and only a certain amount of plastic granules can be placed in the chamber, which significantly affects the drying efficiency. Utility Model Content

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

[0005] A drying device for plastic granules before packaging includes a support and a drying mechanism and agitation mechanism installed on the support. The drying mechanism includes a drying chamber, a cover plate, a baffle plate, a fine mesh plate, an air outlet plate, a hot air blower, and pipes. At least two drying chambers are fixedly installed on the support. The cover plate covers the top of the drying chamber. The baffle plate is slidably inserted into a groove on one side wall of the drying chamber. The fine mesh plate is fixedly installed on the inner wall of the drying chamber. The air outlet plate is fixedly installed at the bottom of the drying chamber. The hot air blower is located below the drying chamber and is connected to the air outlet plate through the pipes. The disturbance mechanism includes a disturbance part, a first gear, a second gear, and a reduction motor. The disturbance part is located inside the drying chamber. Its upper end can penetrate through the cover plate, and its lower end penetrates through the fine mesh plate, the air outlet plate, and the bottom of the drying chamber, extending to the lower part of the support upper plate. The first gear is fixedly installed at the bottom end of the disturbance part, and the second gear is installed at the output end of the reduction motor and is connected to the first gear in a transmission manner.

[0006] By adopting the above technical solution and controlling it with a geared motor, more plastic granules can be dried simultaneously, thus accelerating the drying process.

[0007] The bottom end of the chute on one side wall of the drying chamber is flush with the fine mesh plate.

[0008] The above technical solution facilitates the removal of plastic particles.

[0009] When the baffle is fully embedded in the groove on the side wall of the drying chamber, its highest point is lower than the height of the vent, and the cover plate is also provided with a groove that matches the baffle.

[0010] By adopting the above technical solution, the baffle will not affect the permeation of water vapor and is easy to remove.

[0011] A feeding plate is also provided below the chute on the side wall of the drying chamber, and its width is greater than the width of the chute on the side wall of the drying chamber.

[0012] The above technical solution is used to guide the collection of particles.

[0013] The air outlet plate is composed of a ring and a hollow ring plate with an open inner ring. The opening of the inner ring plate is fixedly connected to the outer wall of the ring. A connection port is provided at the bottom of the ring plate to connect to a pipe.

[0014] By adopting the above technical solution, the air outlet plate can disperse and blow out hot air.

[0015] The beneficial effects of the drying equipment for plastic granules before packaging according to this utility model are: The granules can be placed into the drying chamber by opening the cover plate, and then the cover plate can be placed on top of the drying chamber. The upper end of the agitator passes through the hole in the middle of the cover plate. Then, the hot air blower can be started to transport the hot air through the pipe to the air outlet plate. The air outlet plate blows out from multiple air outlets on the upper panel. The geared motor is started to drive the second gear at its output end. The second gear drives the first gear to rotate, and the first gear drives the agitator to slowly agitate the granules inside the drying chamber until the granules inside the drying chamber are dried. Controlled by a geared motor, more plastic granules can be dried at the same time, which can speed up the drying of materials. Attached Figure Description

[0018] 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.

[0019] This invention provides a drying device, such as a drying device for plastic granules before packaging.

[0020] Includes support 1 and a drying mechanism and a disturbance mechanism installed on support 1. Reference Figure 1-4 The drying mechanism is described in detail below: The drying mechanism includes a drying chamber 2, a cover plate 3, a baffle plate 4, a fine mesh plate 6, an air outlet plate 7, a hot air blower 11, and a pipe 12. The drying chamber 2 consists of at least two parts that are fixedly installed on the support 1. The cover plate 3 covers the top of the drying chamber 2. The baffle plate 4 is slidably inserted into a groove on one side wall of the drying chamber 2. The fine mesh plate 6 is fixedly installed on the inner wall of the drying chamber 2. The air outlet plate 7 is fixedly installed at the bottom of the drying chamber 2. The hot air blower 11 is located below the drying chamber 2 and is connected to the air outlet plate 7 through the pipe 12. Three drying chambers 2 are preferably designed on the support 1, symmetrically arranged about the vertical central axis of the support 1. The reduction motor 13 is installed in the middle of the upper end plate of the support 1. A gear 9 is also set below each of the three drying chambers 2 to drive the agitator 8 to rotate. The agitator 8 consists of a drive shaft and an agitator plate. The agitator plate is fixed in the middle of the agitator 8, and its bottom surface is attached to the upper surface of the fine mesh plate 6 to agitate the plastic particles inside the drying chamber 2.

[0021] The bottom of the chute on one side wall of the drying chamber 2 is flush with the fine mesh plate 6. After the baffle 4 is opened, the plastic particles on the fine mesh plate 6 can fall onto the feed plate 5 for collection. The remaining plastic particles can be scraped off the fine mesh plate 6 with the help of external tools.

[0022] When the baffle 4 is fully embedded in the groove on the side wall of the drying chamber 2, its highest point is lower than the height of the vent 301, and the cover plate 3 is also provided with a groove that matches the baffle 4; when the cover plate 3 is placed on the drying chamber 2, the baffle 4 can also be lifted directly upwards. Below the groove on the side wall of the drying chamber 2, there is also a feed plate 5, the width of which is greater than the width of the groove on the side wall of the drying chamber 2, so that the particles fall onto the feed plate 5 for guidance and collection. During the drying process of the particles, the water vapor generated can be released from the vent 301, which accelerates the drying of the particles in the chamber.

[0023] In order to disperse the hot airflow entering the air outlet plate 7 through the pipe 12, the air outlet plate 7 is designed as follows: the air outlet plate 7 is composed of a ring and a hollow ring plate with an open inner ring. The opening of the inner ring plate is fixedly connected to the outer wall of the ring. A connection port is provided at the bottom of the ring plate to connect with the pipe 12.

[0024] Figure 1 , Figure 2 and Figure 4 The disturbance mechanism is described in detail below: The disturbance mechanism includes a disturbance part 8, a first gear 9, a second gear 10, and a reduction motor 13. The disturbance part 8 is located inside the drying chamber 2. Its upper end can penetrate the cover plate 3, and its lower end successively penetrates the fine mesh plate 6, the air outlet plate 7, and the bottom of the drying chamber 2 and extends to the lower part of the upper end plate of the support 1. The first gear 9 is fixedly installed at the bottom end of the disturbance part 8, and the second gear 10 is installed at the output end of the reduction motor 13 and is connected to the first gear 9 in a transmission manner.

[0025] The implementation principle of a drying device for plastic granules before packaging according to an embodiment of this application is as follows: The granules can be placed into the drying chamber 2 by opening the cover plate 3 and then covering the top of the drying chamber 2 with the cover plate 3. The upper end of the disturbance part 8 passes through the hole in the middle of the cover plate 3. Then the hot air blower 11 can be started to deliver the hot airflow from the pipe 12 to the air outlet plate 7. The air outlet plate 7 blows out from multiple air outlets on the upper panel and starts the reduction motor 13 to drive the gear 2 10 at its output end. The gear 2 10 drives the gear 1 9 to rotate, and the gear 1 9 drives the disturbance part 8 to slowly disturb the granules inside the drying chamber 2 until the granules inside the drying chamber 2 are dried. During the drying process, the generated moisture can pass through the vent 301 to facilitate the drying of the particles inside the drying chamber 2. After drying, the geared motor 13 can continue to drive the agitator 8 to rotate slowly (or the geared motor 13 can be stopped, and when cleaning the remaining particles later, the geared motor 13 can be driven to drive the agitator 8 to push the remaining particles to the position of the feed plate 5 to facilitate the removal of the particles, or the cover plate 3 can be opened and the remaining small amount of particles can be removed by hand). The baffle 4 can be slowly lifted upwards, and some particles can run directly out of the drying chamber 2 and fall onto the feed plate 5, where they are collected by the guidance of the feed plate 5. The remaining particles can be scraped out of the drying chamber 2 with the help of external tools.

[0026] 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.
