Technical Field

[0001] The utility model relates to the technical field of PTC thermistor processing, in particular to a dust removal device for spraying in PTC thermistor processing. Background Art

[0002] PTC is the abbreviation of Positive Temperature Coefficient, which means positive temperature coefficient, and generally refers to semiconductor materials or components with a large positive temperature coefficient. The PTC we usually refer to is a positive temperature coefficient thermistor, or PTC thermistor for short. PTC thermistor is a typical semiconductor resistor with temperature sensitivity. When the temperature exceeds a certain value (Curie temperature), its resistance value increases stepwise as the temperature rises.

[0003] The process of PTC resistor processing often needs to use spray granulation, which requires a spray dryer. The spray dryer needs to introduce external air during operation. There are impurities such as dust in the external air, so it needs to be dusted.

At the same time, the dust in the air cannot be effectively removed. For this reason, we propose a dust removal device for PTC thermistor processing spray. Utility Model Content
