The utility model discloses a dipping device for improving the utilization rate of a flame retardant, and relates to the technical field of textile processing. The dipping device comprises a dipping box, a base plate, a third stand column, a top plate and a spraying pipe, the base plate is fixed to one end of the top face of the dipping box, two scraping plates which are symmetrically distributed are arranged above the base plate, scraping teeth which are distributed at equal intervals are fixed to the opposite faces of the two scraping plates, and brush rollers which are symmetrically distributed are further arranged above the base plate. A guide roller is rotationally connected between the opposite faces of the two third stand columns. A top plate is further arranged above the dipping box on the side, away from the scraper, of the guide roller, and multiple sets of rollers distributed at equal intervals are rotationally connected between the two transverse plates. Through the arrangement of the scraping plate, the brush roller, the top plate, the air cylinder, the redirection roller, the roller and the spray pipe, the problems that thread residues and floating ash exist before fabric impregnation, a large amount of accumulation exists during fabric impregnation, wrinkles are easily caused, flame retardants cannot be fully contacted, the fabric cannot be quickly and efficiently impregnated, and the utilization rate of the flame retardants is increased are solved.

This disclosure relates to an air compression heat pump system, which forms a first air passage, a second air passage, and a third air passage. The first air passage inputs air from a target temperature-controlled space into a recovery heat exchanger for heat exchange, and then inputs the heat-exchanged air back into the first air passage or discharges it into the external environment. The second air passage sequentially inputs air from the first air passage or from the external environment into a first heat exchanger, a second heat exchanger, and a recovery heat exchanger for heat exchange, and then inputs the heat-exchanged air into the target temperature-controlled space or discharges it into the external environment. The third air passage inputs air from the external environment into the first and second heat exchangers for heat exchange, and then inputs the heat-exchanged air into the target temperature-controlled space or discharges it into the external environment. This disclosure utilizes air from the target temperature-controlled space or the external environment to regulate the temperature of the target temperature-controlled space, resulting in high temperature regulation efficiency, no environmental impact, low operating pressure, and no safety hazards.
