Description

Technical Field

[0001] The utility model relates to the field of heating devices, in particular to a heating device for an injection molding machine dryer. Background Art

[0002] Dryers can be divided into two types: industrial and civil. Industrial dryers are also called drying equipment or dryers. Civil dryers are a type of washing machinery. They are generally used to remove moisture from clothing and other textiles after washing and dehydration. Dryers have several modes such as belt drying, drum drying, box drying, tower drying, etc. The heat sources include coal, electricity, gas, etc. The materials are dried in hot air flow and radiation methods during the drying process. Hot air drum drying is a process in which the hot air flow moves from the tail to the front, fully contacts the material, and fully utilizes the heat transfer through heat conduction, convection, and radiation. The heat energy is directly transferred to the material, so that the moisture of the material is continuously evaporated in the cylinder. The induced draft device at the feed inlet draws out a large amount of moisture and wet air flow to prevent secondary pollution caused by dust discharge. The material movement is promoted through internal spiral stirring, sweeping, and copying to complete the entire drying process. Countercurrent conduction dehumidification avoids reducing repeated drying procedures.

[0003] When a dryer is used to dry the materials processed by the injection molding machine, its heating device lacks a filtering structure for external materials, which may cause dust and other debris to be blown onto the surface of the material during drying, thereby affecting the appearance of the material.

[0004] Therefore, it is necessary to propose a heating device for an injection molding machine dryer to solve the above problems. Utility Model Content
