Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of regenerated plastic production, specifically is regenerated plastic cleaning drying integrated device. BACKGROUND

[0002] Regenerated plastic refers to the new plastic material that is processed by physical or chemical methods from recycled and used or discarded plastics. In the production process of regenerated plastic, the cleaning link is crucial because it directly affects the quality of regenerated plastic. In order to ensure the cleaning effect, it is usually necessary to use a special cleaning device to thoroughly clean the regenerated plastic particles. However, the existing cleaning equipment generally has some defects. For example, most cleaning devices, due to the limitation of their structural design, only have cleaning function and cannot integrate drying function. In this way, after cleaning is completed, the plastic particles often need to be transferred to a separate drying equipment for drying treatment. This transfer process not only increases the investment cost of production equipment, but also prolongs the production process of regenerated plastic and reduces the production efficiency.

[0003] The patent with publication number CN220027981U discloses a regenerated plastic cleaning and drying integrated device, which includes a cleaning tank, a support frame fixedly installed on the surface of the cleaning tank, and a cover. The cover is arranged on the top surface of the cleaning tank and is used to close the top of the cleaning tank. An installation pipe is connected to the center of the cover, and a ventilation plate is fixedly installed inside the bottom end of the installation pipe. In the above-mentioned scheme, the cover is covered on the top of the cleaning tank, and cleaning liquid is added through the opening on the top of the cover. After cleaning is completed, the electric push rod installed on the surface of the cleaning tank is extended, and heat is generated by the heating resistance wire, which is matched with the fan installed on the top surface of the cover to blow air, so that the heat can diffuse to the inside of the cleaning tank. The plastic particles in the cleaning tank can be dried, so that the cleaning device not only has the function of drying, but also can recycle the cleaning liquid, thereby improving the practicability of the device.

[0004] The prior art has the following problems: the plastic particles cannot be effectively cleaned when the plastic particles are stacked in the middle or bottom of the cleaning tank; the plastic particles are easily lost with the drainage during the separation of the closing device and the cleaning tank; the hot air generated by the heating resistance wire and the fan cannot effectively penetrate between the stacked plastic particles after the wastewater is discharged, resulting in poor drying effect and directly affecting the cleaning and drying efficiency of the regenerated plastic.
