Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a drying device for plastic raw materials. Background Technique

[0002] Plastic raw materials are mainly divided into thermoplastic and thermosetting plastics according to the molecular structure of synthetic resins: Thermoplastic plastics refer to plastics that are still plastic after repeated heating: The main common raw materials are PE / PP / PVC / PS / ABS / PMMA / POM / PC / PA, etc. Thermosetting plastics mainly refer to plastics made from synthetic resins that are hardened by heating, such as some phenolic plastics and amino plastics.

[0003] For example, in the utility model with the application number 202122255945.6, a multifunctional plastic product processing device is disclosed. A multifunctional plastic product processing device can drive a stirring component to rotate through a driving motor, so as to break up the blocks in the plastic raw materials. The hot air generated by the dryer is conveyed into the stirring barrel through the stirring component, and the plastic raw materials in the stirring barrel are dried. In addition, it can monitor the dryness and humidity of the gas discharged from the exhaust hole in real time, accurately grasp the dryness and humidity of the raw materials in the stirring barrel, and adjust the drying time according to the dryness and humidity data generated by the humidity sensor, improve the drying effect, and effectively improve the quality of the plastic raw materials.

[0004] There are still deficiencies in the similar applications as above:

[0005] This kind of multifunctional plastic product processing device breaks up the plastic raw materials by rotating the stirring component, but does not perform pre-stirring treatment on the raw materials. Stirring and breaking up the raw materials during the heating process will lead to a decrease in drying efficiency and is likely to cause damage to the raw materials.

[0006] Therefore, a drying device for plastic raw materials is designed to optimize the above problems. Content of the Utility Model

DETAILED DESCRIPTION

[0023] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0024] Embodiment 1

[0025] like Figures 1-3As shown in the figure, this embodiment provides a drying device for plastic raw materials, including a drying cylinder 1. A filter screen 11 is provided on one side of the drying cylinder 1. A rotating shaft 2 is rotatably installed inside the drying cylinder 1. Stirring blades 3 are evenly arranged on the outer side of the rotating shaft 2. One end of the rotating shaft 2 away from the filter screen 11 is fixed with a main bevel gear 4. At the top of the drying cylinder 1 near the main bevel gear 4, a pre-stirring bin 5 is installed. A motor 6 is installed on the top of the pre-stirring bin 5. The output shaft of the motor 6 is fixed with a fixed shaft 7. A sub-bevel gear 8 is fixed at the bottom end of the fixed shaft 7, and the sub-bevel gear 8 meshes with the main bevel gear 4. Sieve meshes 9 are evenly arranged on the outer side of the fixed shaft 7. Stirring blades 10 are fixed inside the pre-stirring bin 5. A blower 12 is installed at one end of the drying cylinder 1 near the filter screen 11. An air outlet pipe 13 is fixed at the output end of the blower 12. The top end of the air outlet pipe 13 is fixed with a heating bin 14. Heating pipes 15 are installed inside the heating bin 14. Fixed rods 16 are symmetrically installed on the outer side of the rotating shaft 2 near the filter screen 11. Brush plates 17 are arranged on one side of each fixed rod 16.

[0026] Pour the plastic raw materials into the pre-stirring bin 5. Turn on the blower 12 and the motor 6 respectively. The motor 6 drives the fixed shaft 7 and the stirring blades 10 to rotate, pre-stirring and dispersing the raw materials, so that the dispersed raw material particles pass through the sieve meshes 9 and enter the drying cylinder 1. At the same time, the fixed shaft 7 drives the main bevel gear 4 and the rotating shaft 2 to rotate through the sub-bevel gear 8, prompting the rotating shaft 2 and the stirring blades 3 to rotate to stir the plastic raw materials. The blower 12 sucks the air inside the drying cylinder 1 into the air outlet pipe 13 and then into the heating bin 14. The air is heated by the heating pipes 15 to dry the plastic raw materials inside the drying cylinder 1. While the rotating shaft 2 rotates, it drives the fixed rods 16 and the brush plates 17 to rotate, so that the brush plates 17 clean one side of the filter screen 11, and dredge the dust and impurities adhering to the filter screen 11.

[0027] Embodiment Two

[0028] In this embodiment, as Figures 1-3 shown, a fixing plate 18 is fixed inside the heating bin 14. Through holes one 19 are evenly opened at the top of the fixing plate 18. A movable plate 20 is slidably installed at the bottom of the fixing plate 18, and one end of the movable plate 20 penetrates and extends to the outside of the heating bin 14. Through holes two 21 are evenly opened at the top of the movable plate 20.

[0029] Horizontally pull the movable plate 20 to drive the through holes two 21 on the movable plate 20 to move, prompting the through holes two 21 to align or stagger with the through holes one 19, and adjusting the size of the overlapping part of the through holes one 19 and the through holes two 21, thereby adjusting the flow rate of the hot air inside the drying cylinder 1.

[0030] In this embodiment, a pulling handle is fixed on one side of the movable plate 20, and a holding block is arranged on the outer side of the pulling handle.

[0031] The setting of the pull handle and the grip block facilitates the staff to pull the movable plate 20 to slide, making it more convenient to use.

[0032] In this embodiment, a protective shell is sleeved at the connection of the secondary bevel gear 8 and the primary bevel gear 4, and the top of the protective shell is set as an inclined surface.

[0033] The setting of the protective shell protects the secondary bevel gear 8 and the pre-stirring bin 5, reducing damage caused by plastic raw materials.

[0034] In this embodiment, a protective layer is fixed on the outer side of the air outlet pipe 13, and the protective layer is a temperature isolation layer.

[0035] The setting of the temperature isolation layer improves the protection of the air inside the air outlet pipe 13 and prevents the loss of temperature.

[0036] The above is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and concept of the present utility model, makes equivalent substitutions or changes, all belong to the protection scope of the present utility model.
