Description

Technical Field

[0001] The utility model belongs to the technical field of spiral corrugated pipe processing, and in particular relates to a drying device for processing polyethylene spiral corrugated pipes. Background Art

[0002] In the process of processing polyethylene spiral corrugated pipes, it is necessary to spray or coat the pipes with plastic after processing. After spraying or coating, it is necessary to dry the pipes to ensure that the spray or coating is reliably attached to the polyethylene spiral corrugated pipes and to ensure the processing quality of the polyethylene spiral corrugated pipes.

[0003] At present, the plastic spraying or plastic coating of polyethylene spiral corrugated pipes is usually carried out by rotating them and then directly drying them with a heater to achieve the purpose of processing and drying. Although this method can also complete the processing and drying of polyethylene spiral corrugated pipes, most of the heat is left inside the drying box or directly discharged after use. The former will cause the heat fluidity inside the drying box to be weak, and uneven heating and drying often occur, resulting in poor adhesion of plastic spraying or plastic coating, affecting the processing quality of polyethylene spiral corrugated pipes and the product quality of polyethylene spiral corrugated pipes; while the latter will cause the heat to be lost, resulting in high energy consumption during the drying process, resulting in an increase in the production cost of polyethylene spiral corrugated pipes, and poor economic benefits; in addition, during use, the existing drying devices mostly adopt the method of clamping and rotating the two ends of the polyethylene spiral corrugated pipe or supporting the inside by passing a support column in the middle of the polyethylene spiral corrugated pipe. The former will cause the polyethylene spiral corrugated pipe to be easily deformed due to the large force in the middle during drying, while the latter needs to select different support columns for support according to the diameter of the polyethylene spiral corrugated pipe, and the replacement speed is slow, and if it matches the inner diameter of the polyethylene spiral corrugated pipe, it will be difficult to set and remove.
