Description

Technical Field

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

[0002] Plastic granules refer to granular plastics, generally classified into more than two hundred types, with thousands of subcategories. Common plastic granules include general-purpose plastics, engineering plastics, and specialty plastics. Plastic granules can be used in multiple fields, such as manufacturing furniture, kitchenware, machine housings, and pipes. During the production of plastic granules, in order to prevent excessive moisture content from affecting the quality of subsequent plastic products, they need to be dried. This requires the use of drying equipment. However, existing drying equipment cannot effectively separate plastic granules during use, resulting in many granules sticking together, affecting the quality of the plastic granules and leading to low drying uniformity and efficiency. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a drying device for plastic granule production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A drying device for producing plastic granules includes a support frame, a drying cylinder vertically fixed above the support frame, a lower cover plate rotatably connected to the bottom of the drying cylinder via a hinge, a feeding cylinder fixed to the left side of the upper surface of the drying cylinder, a hot air blower fixed to the right side of the upper surface of the drying cylinder, a servo motor fixed to the middle of the upper surface of the drying cylinder via a bracket, a stirring rod vertically embedded in the middle of the drying cylinder, extension plates fixed to both the left and right ends of the outer wall of the stirring rod, stirring blades fixed to the ends of the extension plates away from the middle of the stirring rod, a connecting ring fixed to the top of the stirring rod, and an outer ring plate nested outside the connecting ring.

[0006] Preferably, the two stirring blades are symmetrically arranged at the left and right ends of the bottom of the stirring rod, and the outer wall of the stirring blades is in close contact with the inner wall of the drying cylinder.

[0007] Preferably, both the stirring blade and the extension plate are provided with interconnected hollow channels inside, and the front and rear ends of the stirring blade are provided with exhaust holes that are interconnected with the hollow channels inside.

[0008] Preferably, the servo motor is rotatably connected to the stirring rod via a transmission shaft, the stirring rod is hollow inside, and the hollow channel inside the extension plate is connected to the inside of the stirring rod.

[0009] Preferably, the outer wall of the connecting ring is tightly attached to the inner wall of the outer ring plate, the bottom of the outer ring plate is connected to the top of the drying cylinder through a connecting rod, and the pipe at the exhaust end of the hot air blower is connected to the interior of the outer ring plate.

[0010] Preferably, a hollow annular guide groove is provided on the outer side of the connecting ring, and an air inlet hole communicating with the inside of the guide groove is provided inside the guide groove.

[0011] During the drying process, the servo motor drives the stirring rod to rotate via the drive shaft, which in turn drives the extension plate and stirring blades to rotate. As the stirring blades rotate, their outer walls are in close contact with the drying cylinder, preventing some plastic particles from accumulating on the inner wall and bottom of the drying cylinder for extended periods, thus reducing drying dead zones. During the rotation of the stirring blades, hot air generated by the hot air blower enters the outer ring plate through pipes, then flows along the guide groove and air inlet in the connecting ring into the interior of the stirring rod, and then enters the hollow channels inside the extension plate and stirring blades. Finally, it is discharged from the exhaust holes at the front and rear ends of the stirring blades, blowing towards the plastic particles being stirred. This results in a better drying effect for the plastic particles and makes the process more convenient. Attached Figure Description

[0017] Support frame 1, drying cylinder 2, lower cover plate 201, feeding cylinder 202, hot air blower 203, servo motor 3, stirring rod 4, extension plate 401, stirring blade 402, connecting ring 403, outer ring plate 404. Detailed Implementation

[0018] Example 1, referring to Figure 1-4A drying device for producing plastic granules includes a support frame 1. A drying cylinder 2 is vertically fixed above the support frame 1. A lower cover plate 201 is rotatably connected to the bottom of the drying cylinder 2 via a hinge. A feeding cylinder 202 is fixed to the left side of the upper surface of the drying cylinder 2. A hot air blower 203 is fixed to the right side of the upper surface of the drying cylinder 2. A servo motor 3 is fixed to the middle of the upper surface of the drying cylinder 2 via a bracket. A stirring rod 4 is vertically embedded in the middle of the drying cylinder 2. An extension plate 401 is fixed to both the left and right ends of the outer wall of the stirring rod 4. A stirring blade 402 is fixed to the end of the extension plate 401 away from the middle of the stirring rod 4. A connecting ring 403 is fixed to the top of the stirring rod 4. An outer ring plate 404 is nested on the outside of the connecting ring 403.

[0019] Two stirring blades 402 are symmetrically arranged at the left and right ends of the bottom of the stirring rod 4, and the outer wall of the stirring blades 402 is in close contact with the inner wall of the drying cylinder 2;

[0020] The servo motor 3 is rotatably connected to the stirring rod 4 via a transmission shaft. The stirring rod 4 is hollow inside, and the hollow channel inside the extension plate 401 is connected to the inside of the stirring rod 4.

[0021] During the drying process, the plastic granules are poured into the drying cylinder 2. The servo motor 3 drives the stirring rod 4 to rotate through the transmission shaft. This causes the stirring rod 4 to drive the extension plate 401 and the stirring blade 402 to rotate. As the stirring blade 402 rotates, its outer wall is in close contact with the drying cylinder 2, which can prevent some plastic granules from accumulating on the inner wall and bottom of the drying cylinder 2 for a long time, thus reducing the dead corners in the subsequent drying of the plastic granules.

[0022] Example 2 differs from Example 1 in that, in this example, both the stirring blade 402 and the extension plate 401 are provided with interconnected hollow channels, and the front and rear ends of the stirring blade 402 are provided with exhaust holes that are interconnected with the hollow channels inside.

[0023] The outer wall of the connecting ring 403 is tightly attached to the inner wall of the outer ring plate 404. The bottom of the outer ring plate 404 is connected to the top of the drying cylinder 2 through a connecting rod. The pipe at the exhaust end of the hot air blower 203 is connected to the interior of the outer ring plate 404.

[0024] A hollow annular guide groove is provided on the outer side of the connecting ring 403, and an air inlet hole that communicates with the inside of the stirring rod 4 is provided inside the guide groove.

[0025] When the servo motor 3 drives the stirring rod 4 to rotate, the connecting ring 403 on the stirring rod 4 will rotate inside the outer ring plate 404 at the same time. Since the outer wall of the connecting ring 403 is in close contact with the outer ring plate 404 and the outer ring plate 404 is provided with a guide groove, when the hot air enters the outer ring plate 404, it will enter the interior of the stirring rod 4 along the guide groove and the air inlet of the guide groove, thereby realizing the simultaneous stirring and drying of plastic particles.

[0026] During the rotation of the stirring blade 402, the hot air generated by the hot air blower 203 enters the outer ring plate 404 through the pipe, then enters the stirring rod 4 through the guide groove and air inlet in the connecting ring 403, and then enters the hollow channel inside the extension plate 401 and the stirring blade 402, and is then discharged from the exhaust holes at the front and rear ends of the stirring blade 402, blowing towards the plastic granules being stirred. This has a better drying effect on the plastic granules and makes it more convenient to use.

[0027] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
