Description

Technical Field

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

[0002] Plastic production is a process of manufacturing plastic products using petroleum, natural gas, and other raw materials through a series of complex processes. It covers multiple key links, from the polymerization reaction of raw materials to generate basic resin, to the addition of various additives for modification according to different needs, and then to the transformation of plastics into products of various shapes and sizes through molding processes such as injection molding, blow molding, and extrusion.

[0003] In plastic production, drying equipment is needed to heat and dry plastic granules. Existing drying equipment stirs and agitates the granules within the drying chamber to ensure effective drying. However, the drying chamber itself cannot rotate, so stirring is typically limited to a fixed position, making it difficult to cover all areas within the chamber. Furthermore, the lack of rotation means the hot air flow path is relatively fixed, easily creating localized hot air circulation zones while other areas experience slow airflow, impacting drying efficiency. Additionally, the gas entering the drying chamber is at room temperature, which cannot be preheated with current technology. Upon entering the chamber, the gas must absorb heat to raise its own temperature before it can heat and dry the granules, resulting in slow temperature increases and reduced production efficiency.

This embodiment provides a plastic granule drying device for plastic production, including a support frame 1, a support base 2 fixed on one side of the support frame 1, a rotating rod 3 rotatably connected to the inner wall of the support base 2, a mounting base 4 fixed to the top of the rotating rod 3, a cylinder 5 disposed inside the mounting base 4, a drive assembly 6 for driving the cylinder 5 to rotate disposed inside the support frame 1, an air inlet hood 7 fixed to the top of the cylinder 5, a heating assembly 8 disposed on the top of the air inlet hood 7, a filter screen 9 disposed inside the air inlet hood 7, a partition 10 fixed to the inner wall of the cylinder 5, and a first heating rod 11 and a heating cylinder 12 respectively fixed to the top of the partition 10.

[0022] The drive assembly 6 drives the rotating rod 3 and the mounting base 4 to rotate, causing the cylinder 5 to rotate. This allows the plastic granules placed inside the cylinder 5 to continuously tumble and roll, ensuring that all surfaces of the plastic granules are fully exposed to the drying environment, thus avoiding the problem of insufficient drying in certain areas. The air inlet hood 7 guides hot air into the cylinder 5 and filters dust. The heating assembly 8 preheats the airflow entering the cylinder 5, which greatly shortens the time required for the plastic granules to reach a dry state, thereby significantly improving the efficiency of the entire drying process. The filter screen 9 filters the gas entering the cylinder 5. The first heating rod 11 directly heats the heating cylinder 12, thereby heating and drying the plastic granules inside the heating cylinder 12.

[0023] The drive assembly 6 includes a drive member 61 disposed inside the support frame 1. A second bevel gear 62 is disposed on the outer side of the drive member 61.

The outer side of the drive rod 63 is rotatably connected to the inner wall of the support frame 1, and the bottom of the drive rod 63 is connected to the bottom of the rotating rod 3 by belt drive.

[0024] The drive unit 61 can drive the second bevel gear 62 and the drive rod 63 to rotate. The drive rod 63 drives the rotating rod 3 to rotate via a belt, thereby causing the mounting base 4 and the cylinder 5 to rotate, making the cylinder 5 rotate and improving the drying uniformity of the plastic granules inside the cylinder 5.

[0025] The heating assembly 8 includes a connecting bracket 81 mounted on the top of the air inlet shroud 7, a fan 82 fixed to the inner wall of the connecting bracket 81, a mounting bracket 83 fixed to the bottom of the connecting bracket 81, and a second heating rod 84 mounted on the bottom of the mounting bracket 83.

[0026] The gas inside the air inlet shroud 7 is preheated by the second heating rod 84, and the heated gas is blown into the cylinder 5 by the fan 82 to dry and heat the plastic granules, thereby improving the heating efficiency of the plastic granules inside the cylinder 5.

A first bevel gear 613 is fixed to the output end of the first motor 612, and the outer side of the first bevel gear 613 meshes with the outer side of the second bevel gear 62.

[0029] The first motor 612 can drive the first bevel gear 613 to rotate, the first bevel gear 613 drives the second bevel gear 62 and the drive rod 63 to rotate, and the drive rod 63 drives the mounting base 4 and the cylinder 5 to rotate.

[0030] Specifically, a fixing seat 13 for supporting the cylinder 5 is fixed on one side of the support frame 1, and multiple sets of locking blocks 14 are fixed on the outside of the cylinder 5, and the outside of the locking blocks 14 is engaged with the inner wall of the mounting seat 4.

[0032] Example 3: This is the third embodiment of the present invention, which is based on the first two embodiments.

[0033] Specifically, an installation frame 15 is fixed to the inner wall of the air inlet hood 7, and multiple sets of clamping rods 16 are fixed to the top of the installation frame 15. A frame 17 is fixed to the outer side of the filter screen 9, and the inner wall of the frame 17 is engaged with the outer side of the clamping rods 16.

[0034] The frame 17 is snapped onto the outside of the lever 16, thereby installing the filter screen 9 and the frame 17, and facilitating the subsequent disassembly and cleaning of the filter screen 9.

[0035] Specifically, a second motor 18 is fixed to the inner wall of the cylinder 5, a fixing rod 19 is fixed to the output end of the second motor 18, and multiple sets of stirring blades 20 for mixing plastic granules are fixed to the outside of the fixing rod 19.

[0036] The second motor 18 drives the fixed rod 19 and the stirring blade 20 to rotate.

[0037] Specifically, the inner wall of the cylinder 5 is connected to the feed pipe 22 and the discharge pipe 21, and both the discharge pipe 21 and the feed pipe 22 are connected to the inner wall of the heating cylinder 12.

[0040] The first connecting block 23 and the second connecting block 24 can be fixed by bolts, thereby installing the connecting frame 81 on the air inlet cover 7, and facilitating the subsequent disassembly of the connecting frame 81.

[0041] In use, open the sealing cap at one end of the feed pipe 22 and feed the plastic granules to be dried into the heating cylinder 12 inside the cylinder 5 through the feed pipe 22. Then close the sealing cap to prepare for the drying process. The second motor 18 starts, driving the fixed rod 19 at the output end to rotate. The stirring blade 20 on the fixed rod 19 rotates accordingly, stirring and mixing the plastic granules inside the heating cylinder 12. The first heating rod 11 directly heats the heating cylinder 12, thereby heating and drying the plastic granules inside the heating cylinder 12. The connecting frame 81 is fixed to the air inlet hood 7 with bolts through the first connecting block 23 and the second connecting block 24. The fan 82 inside the connecting frame 81 operates, drawing in external... The air is preheated as it passes through the second heating rod 84. The hot air enters the cylinder 5 through the air inlet hood 7. The hot air flow can greatly shorten the time required for the plastic granules to reach a dry state. The filter screen 9 filters dust particles in the hot air to ensure that the hot air entering the cylinder 5 is clean. The first motor 612 drives the first bevel gear 613 to rotate, and the second bevel gear 62 rotates accordingly, which in turn drives the drive rod 63 to rotate on the inner wall of the support frame 1. The drive rod 63 drives the rotating rod 3 to rotate through the belt. The rotating rod 3 drives the mounting base 4 and the cylinder 5 to rotate. In conjunction with the stirring blade 20, the plastic granules in the cylinder are constantly turned and rolled to ensure that all surfaces are fully exposed to the drying environment.
