Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in figures 1-3, the premixing stirrer for the fireproof paint comprises a box body 1, wherein the bottom of the box body 1 is fixedly connected with supporting legs 2 which play a role in stably supporting equipment. The top inside box 1 is provided with planetary mechanism, and planetary mechanism includes ring gear 3, main (mixing) shaft 4, planet carrier 5 and three supplementary (mixing) shaft 6, and the vertical setting of main (mixing) shaft 4 is put at the central point of box 1, and the bottom of main (mixing) shaft 4 passes box 1 and rotates the connection in the bottom of box 1, and the top fixedly connected with sun gear 7 of main (mixing) shaft 4, sun gear 7 are located the central point of ring gear 3 and put. Planet carrier 5 is the regular triangle structure, the center of planet carrier 5 is provided with spliced pole 9, spliced pole 9 rotates the top of connecting at box 1, planet carrier 5 is located directly over sun gear 7 and sets up with sun gear 7 interval, three supplementary (mixing) shaft 6 rotates respectively and connects at the three apex of planet carrier 5, supplementary (mixing) shaft 6 is vertical to be set up, be close to planet carrier 5 on every supplementary (mixing) shaft 6 and locate a planet wheel 8 of fixedly connected with, planet wheel 8 meshes with ring gear 3 and sun gear 7 respectively. All be provided with a plurality of puddlers 11 on main (mixing) shaft 4 and the supplementary (mixing) shaft 6, the puddler 11 on the main (mixing) shaft 4 sets up with the 11 dislocation of puddler on the supplementary (mixing) shaft 6, and puddler 11 mutual noninterference when the stirring has the stirring region of overlapping between the puddler 11 in addition, can make intensive mixing between the material, has improved the quality and the efficiency of stirring. The bottom of box 1 is provided with driving motor 10, driving motor 10's output shaft passes through the speed reducer transmission with main (mixing) shaft 4 and is connected, driving motor 10 can drive main (mixing) shaft 4 and rotate, sun gear 7 also can rotate together, when sun gear 7 can drive the rotation of three planet wheel 8, planet wheel 8 still can rotate along ring gear 3, thereby make supplementary (mixing) shaft 6 can the rotation can also revolve round main (mixing) shaft 4, play good stirring effect.
