[0025] The following describes a high-efficiency mixing reaction device for a flame retardant for mining according to an embodiment of the present invention with reference to the accompanying drawings.

The clamping block 6 is fixedly connected to one end of the clamping arm 17 through the sliding hole that passes through the annular enclosure 16. The clamping block 6 is located on the inner side of the annular enclosure 16. The driving mechanism connects and drives all the clamping arms 17 to move synchronously so that all the clamping blocks 6 clamp the mixing tank together. The cover plate 1 is connected to a lifting mechanism 22, which drives the cover plate 1 to move in a direction toward or away from the working position. The outer diameter of the cover plate 1 is equivalent to the outer diameter of the annular enclosure 16. The stirring mechanism is connected to the bottom of the cover plate 1, and the stirring mechanism moves synchronously with the cover plate 1.

[0027] The embodiment of the present invention is provided with a driving mechanism and a plurality of clamping arms 17, so that the driving mechanism controls the synchronous movement of the plurality of clamping arms 17 to clamp mixing tanks of different sizes. The plurality of clamping arms 17 clamp the mixing tank from different directions, which can ensure the stability of the clamping and reduce the shaking of the mixing tank during the flame retardant mixing preparation process. By connecting the cover plate 1 to the lifting mechanism 22 and the stirring mechanism at the same time, the mixing tank can be sealed before operation to prevent the material in the mixing tank from splashing outward during the stirring process. At the same time, the stirring mechanism can be removed after the material in the mixing tank is mixed, and the mixing tank can be directly transported to the place where the material is needed, which is more convenient.

[0028] In some embodiments, Figure 1-2 As shown, the driving mechanism is a gear transmission mechanism, which includes a servo motor 21, a gear ring 12 and a gear set. The gear set is provided with a plurality of groups and is evenly arranged on the outer periphery of the annular enclosure 16. The gear set includes a first gear 9, a second gear 10 and a rotating shaft 8. An annular groove 7 is provided on the outer periphery of the annular enclosure 16. The gear ring 12 is arranged in the annular groove 7 through a limiting device. The upper end of the annular enclosure 16 is fixedly connected to an annular mounting plate 15. The outer diameter of the mounting plate 15 is larger than the outer diameter of the annular enclosure 16. The servo motor 21 is arranged on the mounting plate 15. A rack 18 is provided on the side of the clamping arm 17. A circle of gear teeth is provided on the outer periphery of the gear ring 12. The second gear 10 and the gear ring 12 are connected to the mounting plate 15.

[0029] The embodiment of the present invention only needs one servo motor 21, which can drive all the clamping arms 17 to move through the linkage of the gear set structure to clamp the mixing tank, thereby improving the synchronization of the clamping of the clamping arms 17.

[0030] The working principle is as follows: transport the mixing tank to the working position, drive the servo motor 21, and the first gear 9 and the second gear 10 connected to the servo motor 21 rotate synchronously. Since the second gear 10 is meshed with the gear ring 12, the gear ring 12 rotates accordingly, thereby driving the other second gears 10 meshed with the gear ring 12 to rotate synchronously, thereby driving the other first gears 9 to rotate synchronously. Since the rack 18 of the clamping arm 17 is meshed with the first gear 9, all the clamping arms 17 can achieve synchronous clamping of the mixing tank. After the mixing tank is clamped stably, drive the lifting mechanism 22 to lower the cover plate 1 and the stirring mechanism so that the stirring mechanism extends into the mixing tank. When the stirring mechanism is fully extended into the mixing tank, the cover plate 1 is buckled on the top of the mixing tank. Start the stirring mechanism to mix and stir the materials in the mixing tank.

[0032] In some embodiments, Figure 1 , 4 As shown, an annular protrusion is provided at the edge of the gear ring 12, and an arc-shaped slide groove 111 is provided on the U-shaped block 11. The center of the arc-shaped slide groove 111 of all the U-shaped blocks 11 is concentric with the center of the gear ring 12, forming an annular slideway with a gap. The annular slideway structure can make the gear ring 12 rotate more smoothly.

[0037] In some embodiments, Figure 1 , 3As shown, the rotating rod includes a sleeve 13 and a main telescopic tube 14. The interior of the sleeve 13 is hollow. The main telescopic tube 14 is connected to the interior of the sleeve 13. The sleeve 13 is fixedly connected to the center position of the bottom of the cover plate 1. The main telescopic tube 14 telescopes below the sleeve 13. A first baffle is fixed to the bottom of the interior of the sleeve 13. A second baffle is fixedly connected to the top of the main telescopic tube 14.
