[0002] Biodegradable plastics refer to a type of plastic that is degraded by microorganisms such as bacteria, molds (fungi) and algae that exist in nature. An ideal biodegradable plastic is a polymer material that has excellent performance, can be completely decomposed by environmental microorganisms after being discarded, and is eventually inorganicized to become a component of the carbon cycle in nature. "Paper" is a typical biodegradable material, while "synthetic plastics" are typical polymer materials. Therefore, biodegradable plastics are polymer materials that have the properties of both "paper" and "synthetic plastics".
[0003] Biodegradable bags are produced from biodegradable plastics. During the production process, the mixture is first mixed together and then the plastic is made into small particles through a screw extruder. Since the screw extruder needs to use water for cooling, the plastic made into small particles needs to be dried. Therefore, a quick drying device for biodegradable bag production is now needed.

[0018] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.
[0019] Example
[0020] like Figure 1 - Figure 4 As shown, a quick drying device for producing biodegradable bags comprises a drying box 1, a feeding pipe 2 and an exhaust pipe 4 are arranged at the top of the drying box 1, the exhaust end of the exhaust pipe 4 is bent, and the bending can prevent external dust from entering the inner side of the drying box 1 through the exhaust pipe, so as to avoid the contamination of plastic particles. A drying shell 6 with an upward hemispherical opening is fixedly connected to the inner side of the drying box 1, and a plurality of through holes 12 are opened on the drying shell 6. The diameters of the plurality of through holes 12 are smaller than the diameters of the plastic particles, so as to avoid the plastic particles from being blocked or falling down. When in use, more hot air is blown upward into the drying shell 6 through the through holes 12, so that the plastic particles inside the drying shell 6 are blown up and dried, thereby improving the drying efficiency. The bottom of the drying box 1 is connected to a discharge pipe 9 that passes through the drying box 1, and a valve 10 is provided on the discharge pipe 9. A heating ring 8 is provided in the cavity formed by the lower side of the drying shell 6 and the drying box 1. Multiple heating rings 8 are provided along the outer arc surface of the drying shell 6, and the diameter decreases from top to bottom. An energized base 16 electrically connected to the heating ring 8 is provided on the outside of the drying box 1, and an inspection door 15 cooperating with the heating ring 8 is provided on the front side of the bottom of the drying box 1 to facilitate personnel to inspect or replace the heating ring 8. A fan 13 for blowing air into the cavity is provided on the outside of the drying box 1, and multiple supporting legs 11 are provided at the bottom of the drying box 1. A stirring mechanism for stirring on the upper side of the drying shell 6 is provided on the inside of the drying box 1.
[0021] When in use, the heating ring 8 is powered by the powered base 16 to heat the heating ring 8, and then the gas is blown into the heating ring 8 by the fan 13 to heat the air, so that the heated air is blown into the inner side of the drying shell 6 through the through hole 12. At the same time, through the stirring mechanism, the plastic particles can be blown up and dried while being stirred, thereby increasing the contact area between the hot air and the plastic particles, and ultimately improving the drying effect and efficiency.
[0022] A further improvement on the above scheme is that, Figure 1 , Figure 2 As shown, the stirring mechanism includes a rotating rod 5 vertically rotatably arranged inside the drying box 1, a plurality of stirring rods 14 are fixedly connected to the lower end of the rotating rod 5, the lower ends of the plurality of stirring rods 14 are fixedly connected to a scraper 7 movable on the inner side of the drying shell 6, and a stirring motor 3 for driving the rotating rod 5 to rotate is fixedly connected to the top of the drying box 1.
[0023] When in use, the stirring motor 3 drives the rotating rod 5 to rotate, and then drives the stirring rod 14 and the scraper 7 to rotate inside the drying shell 6, so that the plastic particles are stirred inside the drying shell 6, expanding the contact area between the hot air and the plastic particles, so that the drying effect of the plastic particles is better.
[0024] It should be noted that the rapid drying device for producing biodegradable bags is in use.
[0025] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model.
