Technical Field

[0001] The utility model relates to the technical field of polyethylene plastic masterbatch production, and more specifically, to a feed preheating device for producing polyethylene plastic masterbatch. Background Art

[0002] Polyethylene plastic masterbatch is one of the most commonly used polymer materials. It is currently mainly produced by Sinopec. It has very stable performance and is a non-toxic and environmentally friendly material. Plastic films, plastic bags, food bags, protective films, and electrostatic films on the market are all made of this material. During the production and processing of polyethylene plastic masterbatch, a preheating device is required to preheat it for subsequent processing.

[0003] However, the existing preheating device has a relatively simple preheating method for raw materials, the heat cannot fully contact the raw materials, and it is inconvenient to realize the two states of movement and stable placement of the entire device, which makes manual handling more laborious.

[0004] For example, Chinese patent publication number CN217476355U discloses a feed preheating device for polyethylene plastic production. During the preheating process of the plastic, the structure can turn the plastic over and improve the full contact between the plastic and the preheating air, thereby improving the preheating efficiency of the plastic.

[0005] However, when this structure is actually used, a large amount of powder will be generated in the plastic during the preheating and turning process of the plastic. The powder will diffuse to the outside through the feed port, which will not only easily affect the processing environment, but also easily lead to waste of plastic powder. In view of this, the utility model proposes a feed preheating device for producing polyethylene plastic masterbatch. Utility Model Content

The preheated raw materials can be discharged through the discharge port at the bottom.

[0026] In a specific embodiment, as shown in the attached Figure 1 , 2 As shown in , 3 and 4, a dust collecting structure is arranged on the top of the feeding port 5, and the dust collecting structure includes a dust suction frame 6, which is slidably installed on the top of the feeding port 5, and a dust suction fan 7 is arranged on the top of the dust suction frame 6, and a conveying hose 8 is arranged at one end of the dust suction fan 7.

The multiple stirring rods 21 can mix and stir the plastic to increase the contact area between the plastic and the preheated air. In addition, during the rotation of the stirring rod 21, it will prompt multiple material shovels 22 to rotate. The rotating material shovels 22 can scoop up the plastic from the bottom and scatter it from the top.
