Description

Technical Field

[0001] The invention relates to the field of ultraviolet absorber production equipment, in particular to an ultraviolet absorber raw material feeder. Background Art

[0002] UV absorbers are a class of compounds that can effectively absorb ultraviolet radiation. Through their unique molecular structure and action principle, UV absorbers play an important role in light stabilization in many fields. With the continuous development of science and technology, the performance and application fields of ultraviolet absorbers will continue to expand and improve. In the production of ultraviolet absorbers, the raw materials of ultraviolet absorbers need to undergo multi-step chemical reactions, such as esterification, acylation, condensation, etc., and ultraviolet absorbers need to be prepared in a reactor. When the reactor is used, feeding operations need to be performed. The raw materials of ultraviolet absorbers are solid materials, which are fed through a feeder. The feeding port is generally at the upper end of the feeding reactor. The raw materials of ultraviolet absorbers have odor and are toxic. If the raw materials are directly added into the reactor from the feeding port, the odor continues to emanate from the feeding port, causing the feeding personnel to work in a toxic and odorous environment, which is not conducive to the safety of the operators. When feeding, it is also easy to cause foreign matter to enter the feeder, such as gloves, work cards and other items, resulting in material contamination. When feeding, because it is a solid material, it is also easy to cause some agglomerated products, resulting in blockage during feeding, which is inconvenient to use. Summary of the invention
