The invention discloses a stator winding paint dipping production system and method, and relates to the technical field of stator winding production equipment.The stator winding paint dipping production system comprises a paint dipping box and a storage box, a pumping device used for conveying paint in the paint dipping box is arranged outside the paint dipping box, the paint dipping box is connected with the storage box through the pumping device, and a rotating device is installed on the paint dipping box; a paint scraping mechanism is arranged in the storage box, the stator winding rotates in the paint dipping box through the rotating device, the paint dipping box is connected with the storage box through the pumping device, circulating conveying and flowing of paint in the paint dipping box are achieved, the fluidity of the paint and the permeability of the paint to the stator winding are improved, and the paint dipping efficiency of the stator winding is improved; the rotating device rotates to throw away redundant paint on the stator winding, the redundant paint on the inner hole surface and the outer circle surface of the stator winding is scraped off through the paint scraping mechanism, and efficient paint dipping treatment on the stator winding is achieved.

This invention discloses a high-purity fluorobenzene recovery process in the production of 1,4-bis(4-fluorobenzoyl)benzene, belonging to the field of organic waste liquid recovery technology. Step 1 involves reacting the fluorobenzene waste liquid through a tubular reactor containing anhydrous aluminum chloride particles to obtain dehydrated fluorobenzene waste liquid. The reaction temperature is 5-40℃, the residence time is 60-200 min, and the flow rate of the fluorobenzene waste liquid is 0.1-0.4 m / min. Step 2 involves filtering the dehydrated fluorobenzene waste liquid through a micron filter, then distilling it in a fluorobenzene distillation column. The organic vapor at the top of the column is compressed by a compressor, heat-exchanged by an MVR heat exchanger, condensed, and then refluxed in a reflux tank. High-purity fluorobenzene is obtained from the fluorobenzene distillation column, wherein the fluorobenzene purity is greater than 99.99 wt% and the water content is less than 10 ppm. This invention uses fluorobenzene waste liquid from the production process of 1,4-bis(4-fluorobenzoyl)benzene as raw material. Through reaction dehydration, crystalline aluminum chloride filtration and distillation, it achieves continuous batch production of high-purity fluorobenzene. The process is simple and has low energy consumption.
