The invention discloses a bisphenol AF feeding dust prevention device, which relates to the technical field of feeding dust prevention, and comprises a conveying device, wherein both ends of the conveying device are fixedly mounted with load-bearing plates, a rotating motor is fixedly mounted on the surface of the conveying device, a supporting foot is fixedly mounted on the bottom of the load-bearing plate, vertical rods are fixedly mounted on the top of the load-bearing plate, a feeding frame is fixedly mounted between the vertical rods, a feeding port is provided at the bottom of the feeding frame, a top cover is fixedly mounted on the top of the feeding frame, a feeding port is provided on the surface of the top cover, a partition plate is fixedly mounted inside the feeding frame, a No. 1 spring is fixedly mounted on the top of the partition plate, and the partition plate slowly flows out through the opening of a material distribution funnel, and bisphenol AF does not generate dust when feeding, so that the dust generated by bisphenol AF during rapid feeding is prevented from being flammable or toxic with certain chemical dust, thereby reducing the risk of explosion and poisoning.

This invention belongs to the field of refrigeration, heat pump, and low-boiling-point power cycle technology. It discloses an environmentally friendly mixed refrigerant that can be used in low-ambient-temperature heat pumps and replace R410A, comprising a first component, a second component, and a possible third component. The first component is difluoromethane (R32), the second component is hexafluoropropylene (R1216), and the possible third component is one of propane (R290) or carbon dioxide (R744). The environmentally friendly mixed refrigerant provided by this invention, when used to replace R410A, has a significantly lower global warming potential (GWP) than R410A, demonstrating a clear advantage in environmental friendliness. The thermodynamic properties of the environmentally friendly mixed refrigerant provided by this invention are comparable to or even superior to R410A, making it a complete replacement for R410A in refrigeration, heat pump, and low-boiling-point power cycle systems. Furthermore, it can be used in ultra-low temperature heat pumps, possessing broad application prospects.
