Before the low-toxicity high-flame-retardance unsaturated polyester resin energy-saving reaction kettle is used, heating equipment is arranged at the bottom of the kettle body 5, the kettle body 5 is preheated by using the built-in heating equipment, at the moment, a pump 17 is controlled to operate, the pump 17 drives water in a circulating pipe 16 to circularly flow, the circulating pipe 16 is spirally wound outside the kettle body 5, therefore, heat between an outer housing 2 and the kettle body 5 is timely taken away, the water in the circulating pipe 16 flows back into an isolation box 12, and the water in the isolation box 12 preheats the outer wall of a first blanking cylinder 13, so that heat recycling is realized; resin raw materials begin to be injected into the first blanking barrel 13, the resin absorbs part of heat on the first blanking barrel 13 in advance, energy is effectively saved, after the resin is added, the electric telescopic piece 14 is controlled to operate, the electric telescopic piece 14 drives the push plate 15 to move downwards, the push plate 15 cleans residual resin on the inner wall of the first blanking barrel 13, and meanwhile a sealing ring is arranged between the push plate 15 and the first blanking barrel 13, so that the resin is accelerated to flow to the kettle body 5 by utilizing a piston principle when the push plate 15 is pushed.
When resin flows into the kettle body 5 from the inside of the first blanking cylinder 13, the servo motor 7 on the fixed seat 6 is controlled to run, the output shaft of the servo motor 7 drives the connecting shaft 8 to rotate, the connecting shaft 8 drives the two stirrers 9 on the lower side to rotate, and the bending directions of the paddles on the two stirrers 9 are opposite, so that the resin cannot form vortex in the kettle body 5, meanwhile, the connecting shaft 8 drives the anti-sticking plate 10 to rotate, the anti-sticking plate 10 continuously stirs the resin at the bottom of the kettle body 5, the anti-sticking plate 10 is kept in close contact with the kettle body 5, and the situation that the resin is stuck to the kettle body 5 is effectively avoided; at this time, corresponding powder materials are added according to the amount of resin, and the matched amount of the powder materials is input into the second blanking barrel 19, and the powder materials fall on the dispersing plate 27 along the second blanking barrel 19, so that powder clusters can be formed when the powder materials fall on the surface of the resin directly, and the connecting frame 28 rotates along with the connecting shaft 8 and drives the two cleaning rods 29 and the two scraping plates 30 to rotate, the two scraping plates 30 continuously stir the powder materials on the upper surface of the dispersing plate 27 while rotating, so that the powder materials are dispersed, and meanwhile, the two cleaning rods 29 clean the powder materials remained on the surface of the dispersing plate 27 while rotating, so that the materials are prevented from being adhered on the dispersing plate 27; the powder material falls to the bottom of the kettle body 5 from the blanking holes on the dispersion plate 27 and is mixed with the resin, and the powder material is turned and mixed after contacting with the resin due to the large number of blanking holes and small aperture, so that the surface agglomeration is avoided; because the speed of falling materials in the blanking holes of the discrete plates 27 is limited, partial materials flow out from the gaps at the outer edges of the discrete plates 27, and similarly, in order to avoid centralized scattering of the materials, the connecting shaft 8 drives the three fixed plates 31 to rotate, the three fixed plates 31 respectively drive one shielding plate 32 to rotate, the shielding plates 32 continuously shield the gaps on the discrete plates 27 in the rotating process, the gaps at the bottoms of the discrete plates 27 are intermittently blanked in batches, and the speed of powder blanking is improved while powder agglomeration is effectively avoided.
In the blanking process, as the aperture of the blanking hole on the discrete plate 27 is smaller, the situation of material blockage can occur, the three fixed plates 31 also respectively drive one jacking block 33 to rotate in the process of following the rotation of the connecting shaft 8, the three jacking blocks 33 push a plurality of protection rods 36 at the bottom of the discrete plate 27 in turn in the process of circular motion, the jacking blocks 33 push the protection rods 36, the dredger 35 moves upwards in a following way, the three ejector rods on the dredger 35 correspondingly enter the corresponding blanking holes on the discrete plate 27, the lengths of the three ejector rods are different, but the heights of the three ejector rods entering the blanking holes cannot exceed the upper surface of the discrete plate 27, the normal operation of the cleaning rods 29 and the scraping plates 30 is ensured, the dredger 35 intermittently stretches into the blanking holes of the discrete plate 27, and the blanking speed of powder materials is effectively improved.
