Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle production, in particular to a drying machine for cleaning plastic particles. Background Art

[0002] Plastic granules refer to granular plastics. Common plastic granules include general-purpose plastics, engineering plastics, and special plastics. Before injection molding, the plastic granule raw materials need to be heated and dried to evaporate the moisture on the surface of the plastic granules to prevent the moisture on the plastic granules from causing bubbles in the plastic when the plastic is melted, thus affecting the quality of the plastic product.

[0003] The existing plastic pellet washing dryer needs to drain the washed plastic before drying it, which is inefficient. The plastic pellets need to be tumbled manually during drying to avoid sticking between the plastic pellets. The dried plastic pellets need to be unloaded manually, which is cumbersome and affects production efficiency. Utility Model Content

[0008] Preferably, the bottom end surfaces of the two support rods and the two telescopic rods are commonly connected to a base, and a water collection tank is placed on the top surface of the base. The base ensures that the dryer for cleaning plastic particles can be placed stably on the ground. The water collection tank collects and processes the water sticking to the surface of the plastic particles after passing through the upper filter and the bottom filter.

[0009] Preferably, a hydraulic rod is hingedly installed on the top surface of the base on one side of the water tank, and the top end of the hydraulic rod is hingedly installed on the bottom surface of the bottom filter.

A connecting rod is provided on one side of the top of the turntable, and the other end of the connecting rod is provided on the top of the upper filter. Therefore, the upper filter will be driven to perform reciprocating linear motion, so that the plastic granules are shaken and tumbled continuously, and are blocked by the bottom filter without falling. The sticky water of the plastic granules after cleaning passes through the upper filter and the bottom filter and is collected for treatment. The cleaned plastic granules can be directly dried without draining, and the plastic granules tumble continuously without sticking to each other, thereby avoiding the phenomenon that one side of the plastic granules is melted due to being irradiated by the infrared drying lamp for too long.

[0013] 2. This plastic granule cleaning dryer pushes the bottom filter screen upward through a hydraulic rod to flip it over, with the top of the support rod as the center of the circle, and pours the dried plastic granules out from the discharge port. The discharge can be completed without disassembling the machine body. The operation steps are simple and the efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS
