Description
Technical Field
[0001] This utility model relates to the field of plastic granulation and drying technology, and in particular to a PC plastic granulation and drying device. Background Technology
[0002] PC plastic granulation involves heating and melting the plastic, then extruding the heated and mixed plastic through pipes, cooling it in a cooling water tank, and then cutting the cooled PC plastic strips into granules with specific particle size, appearance, and properties according to the corresponding length. Since PC plastic granulation absorbs water from the cooling water tank during the cooling process, it is necessary to dry the PC plastic granules.
[0003] Existing PC plastic granulation and drying equipment involves placing PC plastic granules in a container and then drying them by introducing hot air into the container. This method results in uneven heating of the PC plastic granules within the container, causing some granules to dry while others remain moist. Continuing to introduce hot air may cause the already dried granules to melt or stick together.
[0004] In view of this, this application proposes a PC plastic granulation and drying apparatus. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a PC plastic granulation and drying device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A PC plastic granulation and drying device includes a shell structure, a heat sealing machine structure mounted on the lower side of the shell structure, a drying structure installed inside the shell structure, and a stirring structure rotatably connected inside the drying structure. The device is characterized in that...
[0008] The drying structure includes an air inlet pipe, an air outlet pipe, and an installation pipe installed within the shell structure. A sealing connecting ring is rotatably connected between the air inlet pipe and the air outlet pipe, and between the air outlet pipe and the installation pipe. The air inlet pipe, the air outlet pipe, the installation pipe, and the sealing connecting ring are interconnected.
[0009] The stirring structure includes connecting blocks arranged in a circumferential array on a sealed connecting ring, with connecting pipes fixedly connected between corresponding upper and lower connecting blocks, and external blowing pipes arranged in an array fixedly connected to the connecting pipes, with the connecting pipes communicating with the external blowing pipes.
[0010] As a further preferred embodiment of this technical solution, the shell structure includes a dryer shell, an upper cover is installed on the dryer shell, an opening and closing hinge is provided between the dryer shell and the upper cover, and a ventilation interception plate is installed inside the dryer shell;
[0011] The heat sealing machine structure includes a hot air duct that runs through and is installed on the dryer housing. A control board is installed on the hot air duct, and a hot air fan is connected to the hot air duct. The hot air duct is connected to the air inlet duct.
[0012] As a further preferred embodiment of this technical solution, a drive shaft is rotatably connected inside the mounting tube, a rotating fan is fixedly connected to the lower end of the drive shaft, and a circumferentially distributed connecting rod is provided between the sealing connecting ring and the drive shaft.
[0013] As a further preferred embodiment of this technical solution, an inner air blowing pipe is fixedly connected to the outer contour of the air outlet pipe in a circumferential array. The inner air blowing pipe is connected to the air outlet pipe. Both the air outlet pipe and the outer air blowing pipe are provided with multiple air holes. The sealing and connecting ring is connected to the connecting block, the air inlet pipe, the air outlet pipe and the mounting pipe.
[0014] As a further preferred embodiment of this technical solution, the connecting block is rotatably connected with symmetrically distributed rotating shafts, the lower end of the rotating shaft is provided with a rotating fan, the rotating shaft is connected to the upper connecting block, and staggered guide baffles are provided inside the connecting block, the guide baffles are respectively provided between the rotating shafts and between the rotating shaft and the air outlet pipe near the air outlet pipe.
[0015] As a further preferred embodiment of this technical solution, the rotating shaft is provided with symmetrically distributed external air blowing pipes. The external air blowing pipes on the rotating shaft near the air outlet pipe are at the same height as the external air blowing pipes on the connecting pipe, while the external air blowing pipes on the other rotating shaft are misaligned with the external air blowing pipes on the connecting pipe.
[0016] This utility model has the following beneficial effects:
[0017] 1. This utility model uses hot air blown into the air inlet pipe from the hot air pipe to make the rotating fan drive the drive shaft to rotate together, which in turn drives the sealing connecting ring to rotate, making the connecting block rotate synchronously. Then, the hot air blown into the lower connecting block drives the rotating fan on the lower side of the rotating shaft to rotate, so that the rotating shaft rotates in the opposite direction with the rotation of the connecting block, thereby achieving the effect of stirring the PC plastic granulation and re-drying in the dryer shell.
[0018] 2. This utility model dries the PC plastic granules inside the dryer housing by blowing hot air in from both the inside and outside. The PC plastic granules are dried by the inner air pipe on the air outlet pipe and the outer air pipe on the connecting pipe. At the same time, the staggered outer air pipes on the rotating shaft dry the PC plastic granules passing through the gaps between the outer air pipes as the rotating shaft rotates in opposite directions. By drying while stirring, the drying efficiency is improved, and the drying effect is more uniform. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] This utility model provides a technical solution: such as Figure 1-5As shown, a PC plastic granulation and drying device includes a shell structure 1, a heat sealing machine structure 2 installed on the lower side of the shell structure 1, a drying structure 3 installed inside the shell structure 1, and a stirring structure 4 rotatably connected inside the drying structure 3. The drying structure 3 includes an air inlet pipe 31, an air outlet pipe 32, and an installation pipe 33 installed inside the shell structure 1. Sealing connecting rings 35 are rotatably connected between the air inlet pipe 31 and the air outlet pipe 32, and between the air outlet pipe 32 and the installation pipe 33. The air inlet pipe 31, the air outlet pipe 32, the installation pipe 33, and the sealing connecting rings 35 are connected in communication. The stirring structure 4 includes connecting blocks 41 circumferentially arrayed on the sealing connecting rings 35. Connecting pipes 42 are fixedly connected between corresponding upper and lower connecting blocks 41. Arrayed external blowing pipes 43 are fixedly connected to the connecting pipes 42, and the connecting pipes 42 are connected to the external blowing pipes 43. The shell structure 1 includes a dryer shell 11. The dryer housing 11 is equipped with an upper cover 12, and an opening and closing hinge 13 is provided between the dryer housing 11 and the upper cover 12. A ventilation interception plate 14 is installed inside the dryer housing 11. The heat sealing machine structure 2 includes a hot air pipe 23 that runs through the dryer housing 11. A control board 21 is installed on the hot air pipe 23, and a hot air fan 22 is connected to the hot air pipe 23. The hot air pipe 23 is connected to the air inlet pipe 31. It should be noted that by placing the PC plastic granules to be dried into the dryer housing 11 and receiving them on the ventilation interception plate 14, the hot air fan 22 is controlled by the operation control board 21 to deliver hot air into the air inlet pipe 31 through the hot air pipe 23. Then, the hot air is blown out from the installation pipe 33. At the same time, the hot air passes through the drying structure 3 and the connecting block 41 and is blown out from the external blowing pipe 43 on the connecting pipe 42. The PC plastic granules are dried from both the inside and outside.
[0030] like Figure 3 and 4 As shown, a drive shaft 37 is rotatably connected inside the mounting pipe 33. A rotating fan 36 is fixedly connected to the lower end of the drive shaft 37. A circumferentially distributed connecting rod 38 is provided between the sealing connecting ring 35 and the drive shaft 37. A circumferentially arrayed inner air blowing pipe 34 is fixedly connected to the outer contour of the air outlet pipe 32. The inner air blowing pipe 34 is connected to the air outlet pipe 32. Multiple air holes are opened on both the air outlet pipe 32 and the outer air blowing pipe 43. The sealing connecting ring 35 is connected to the connecting block 41, the air inlet pipe 31, the air outlet pipe 32, and the mounting pipe 33. It is explained that hot air flows upward through the air inlet pipe 31, which in turn drives the rotating fan 36 and the drive shaft 37 to rotate, causing the sealing connecting ring 35 to rotate synchronously, which in turn drives the connecting block 41 and the connecting pipe 42 to rotate synchronously. By setting the height of the rotating fan 36 to be lower than the sealing connecting ring 35 and the air outlet pipe 32, the hot air blown from the hot air pipe 23 first acts on the rotating fan 36 to rotate, and then blows into the dryer housing 11 through the sealing connecting ring 35 and the air outlet pipe 32 to dry the PC plastic granules.
[0031] like Figure 5As shown, symmetrically distributed rotating shafts 44 are rotatably connected to the connecting block 41. A rotating fan 45 is provided at the lower end of the rotating shaft 44. The rotating shaft 44 is connected to the upper connecting block 41. Staggered guide baffles 46 are provided inside the connecting block 41. The guide baffles 46 are respectively provided between the rotating shafts 44 and between the rotating shaft 44 and the air outlet pipe 32 near the air outlet pipe 32. Symmetrically distributed external air blowing pipes 43 are provided on the rotating shaft 44. The external air blowing pipe 43 on the rotating shaft 44 near the air outlet pipe 32 is at the same height as the external air blowing pipe 43 on the connecting pipe 42. The external air blowing pipe 43 on the other rotating shaft 44 corresponds to the external air blowing pipe 43 on the connecting pipe 42 in a staggered manner.
[0032] It should be noted that the lower connecting block 41 is connected to the connecting pipe 42, and the upper connecting block 41 is connected to the rotating shaft 44. This allows the hot air in the air outlet pipe 32 to be blown into the dryer housing 11 from the external air blowing pipe 43 on the connecting pipe 42 and the rotating shaft 44, respectively. The hot air blown into the lower connecting block 41 changes the rotation direction of the two rotating fans 45 through the staggered guide baffles 46, thus causing the two rotating shafts 44 to rotate in different directions. As a result, the rotating shafts 44 rotate with the connecting block 41. Two rotating shafts 44 rotate in opposite directions to stir the PC plastic granules inside the dryer housing 11. At the same time, the staggered distribution of shafts 43 further stirs the PC plastic granules inside the 11 more evenly during the rotation of the shafts 44. Meanwhile, the PC plastic granules passing through the gap between the shafts 43 on the two shafts 44 are affected by the hot air blown out by the shafts 43, resulting in more even hot air drying of the PC plastic granules. This improves the drying efficiency of the PC plastic granules and ensures the uniformity of the drying process.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
