Description

Technical Field

[0001] This utility model relates to the field of polyethylene processing technology, specifically to an integrated device for cooling and shaping polyethylene particles. Background Technology

[0002] Polyethylene granules are granular products formed after processing polyethylene resin. Polyethylene is a thermoplastic resin polymerized from ethylene monomers. It is a widely used polymer material. Its granular state facilitates storage, transportation, and subsequent processing and molding. Polyethylene granules are usually small, white, semi-transparent particles. Their size varies depending on the production process and application, generally around a few millimeters in diameter. Polyethylene granules have good flexibility; they can be bent to a certain extent without breaking, which allows processed plastic products to withstand a certain degree of deformation. The density of polyethylene granules determines the weight and texture of the products. Polyethylene granules have good chemical corrosion resistance and are resistant to most acids and alkalis. In general acidic or alkaline environments, polyethylene plastic products are not easily corroded.

[0003] When polyethylene granules come out of the extruder or granulator during the production process, they are in a molten state and their shape and size are prone to change. Cooling and shaping devices quickly reduce the temperature of the granules, causing them to change from a viscous flow state to a solid state, thereby fixing the shape of the granules. However, existing cooling and shaping devices leave some dust adhering to the granules during use. Current cooling devices cannot remove the dust, requiring an additional impurity removal process, which reduces processing efficiency. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6This utility model provides a technical solution: an integrated device for cooling and shaping polyethylene granules, comprising a protective shell 1, a crushed material shell 2, a feeding pipe 3, a discharging pipe 4, a drive motor 5, a feeding screw shaft 6, a first gear 7, a second gear 8, a stirring cylinder 9, a mixing blade 10, an air inlet fan 11, an air outlet nozzle 12, a collection box 13, and a filter screen frame 14. The protective shell 1 has a support foot at its lower end. The crushed material shell 2 is fixedly connected to the upper surface of one end of the protective shell 1. The feeding pipe 3 is installed through the upper surface of the crushed material shell 2. The lower surface of one end of the protective shell 1 has a discharge port. The bottom surface of the cavity of the pipe 4 and the crushed material shell 2 is designed to be inclined. The lower side surface of the cavity of the crushed material shell 2 is connected to the cavity of the protective shell 1. The feed pipe 3 and the discharge pipe 4 are staggered left and right. When using this device, the raw material is first introduced into the crushed material shell 2 from the feed pipe 3. The drive motor 5 is started to drive the feeding screw shaft 6 and the first gear 7. The first gear 7 meshes with the second gear 8, thereby driving the stirring cylinder 9 to rotate. This facilitates the rotation of the mixing blades 10 on the surface of the stirring cylinder 9 to stir and disperse the raw material, prevent the raw material from caking and cool it, and improve the effect of subsequent cleaning of dust and impurities on the surface of the raw material.

[0031] A drive motor 5 is fixedly connected to the side surface of the protective shell 1, and a feeding screw shaft 6 is rotatably connected to the inner wall of the cavity of the protective shell 1. The output end of the drive motor 5 passes through the side surface of the protective shell 1 and is fixedly connected to the rotating shaft of the feeding screw shaft 6. The first gear 7 and the second gear 8 are meshed and rotatably connected to the protective shell 1. The upper end of the rotating shaft of the second gear 8 is fixedly connected to the lower end of the stirring cylinder 9. The raw material is guided to the cavity of the protective shell 1 by the inclined bottom surface of the crushed material shell 2, so that the raw material can be driven by the rotation of the feeding screw shaft 6 and move towards the discharge pipe 4. The air is directed to multiple air nozzles 12 by the air inlet fan 11. The linearly arranged air nozzles 12 blow air to cool the raw material. The feeding screw shaft 6 drives the raw material to turn over, which increases the contact area with the air and improves the cooling effect of the raw material. Finally, the raw material is discharged from the discharge pipe 4.

[0032] One end of the feeding screw shaft 6 is fixedly connected to a first gear 7, and a second gear 8 is provided on the side of the first gear 7. A stirring cylinder 9 is rotatably connected to the bottom surface of the cavity of the crushed material shell 2. A mixing blade 10 is fixedly connected to the outer surface of the stirring cylinder 9. The cooling and impurity removal mechanism includes an air inlet fan 11, which is fixedly connected to the upper surface of the protective shell 1. An air duct is opened on the top surface of the cavity of the protective shell 1, and an air outlet nozzle 12 is fixedly connected to the inner wall of the air duct of the protective shell 1. A collection box 13 is provided on the lower surface of the protective shell 1, and a filter screen frame 14 is fixedly connected to the inner wall of the cavity of the protective shell 1. During the movement of the raw material, the raw material is supported by the filter screen frame 14, which facilitates the passage of fine dust and impurities through the filter screen frame 14 and their fall into the collection box 13, thereby removing impurities from the raw material and improving its quality.

[0033] The protective housing 1 is equipped with a cooling and impurity removal mechanism. It cools the raw material through the inlet fan 11 and the outlet nozzle 12, and collects impurities through the collection box 13. The outlet of the inlet fan 11 is connected to the air duct of the protective housing 1. The outlet nozzle 12 is horizontally and evenly arranged. The collection box 13 is connected to the lower surface of the protective housing 1. The filter frame 14 is arc-shaped and its width is smaller than the width of the opening of the collection box 13. While the raw material is cooled by the air blown by the outlet nozzle 12, the air will peel off the dust and impurities on the surface of the raw material, thereby improving the impurity removal effect of the device on the raw material.

[0034] Working principle: When using this integrated polyethylene granule cooling and shaping device, the raw material is introduced into the crushing shell 2 through the feed pipe 3. The drive motor 5 drives the feeding screw shaft 6 and the first gear 7 to rotate, which in turn drives the second gear 8 and the stirring cylinder 9 to rotate. This allows the mixing blades 10 to stir and disperse the raw material to prevent clumping. After the raw material enters the protective shell 1, the feeding screw shaft 6 drives the raw material to move. At the same time, the air blower 11 blows air onto the raw material through the air nozzles 12 to cool it down. The air also helps to remove dust and impurities from the surface of the raw material. The dust and impurities will fall into the collection box 13 through the filter frame 14. Finally, the raw material is discharged from the discharge pipe 4, which increases the overall practicality.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
