Abstract

The invention discloses a powder coating closed circulation pulverizer unit. The powder coating closed circulation pulverizer unit comprises a pulverizer, a cyclone separation unit, a bag dust collector and an induced draught fan which are connected in sequence, wherein the dust collector unit further comprises an evaporator arranged behind the induced draught fan; the evaporator is externally connected with a refrigerating compressor unit and communicates with the pulverizer; the evaporator also communicates with a tablet compressing cooling crusher in front of the pulverizer. Through the arrangement, gas and dust both circulate in pulverizer equipment or are collected by the dust collector for reutilization, so that atmospheric pollution is avoided, the utilization rate of raw materials is high. Through the additional arrangement of the refrigerating compressor unit, the temperature in the whole circulation can be lowered, the temperature of the pulverizer can be lowered, lasting rising of the temperature in the pulverizer is avoided, and the quality of produced coating is guaranteed.

Description

technical field [0001] The invention relates to powder coating processing equipment, in particular to a powder coating closed-circuit circulation milling unit. Background technique [0002] Powder coatings are widely used in various fields due to their advantages of no organic solvent, good environmental protection, convenient storage and transportation. [0003] At present, the Chinese patent whose publication number is CN105599168A discloses an automatic integrated device for producing powder coatings, which includes a mixer, an extruder, a tablet press, a mill and a dust removal box, and is characterized in that: A discharge station is provided, the mixer communicates with the extruder through the discharge station, the feed port of the tablet press is fixedly connected with the discharge port of the extruder, and the press The discharge port of the chip machine is connected to the pulverizer through a feeding pipeline, a cyclone separator is provided between the pulveri...
