[0030] Working principle:

[0031] At the beginning of the operation, the refractory material to be mixed is poured into the feeding hopper 41, and the raw materials fall into the mixing cylinder 1 along the feeding pipe 42 under the action of gravity, and the feeding is completed.

[0032] The speed reducer motor 62 is started, the output shaft of the speed reducer motor 62 drives the driving pulley 63 to rotate, the driving pulley 63 drives the driven pulley 64 on the stirring shaft 5 through the belt transmission, so that the stirring shaft 5 starts the circumferential rotation, and then the connecting rods 7, the mounting rods 8 and the arc-shaped paddles 9 make the circumferential motion, since the arc-shaped paddles 9 on the two mounting rods 8 are staggered arranged, when the stirring shaft 5 rotates, the arc-shaped paddles 9 continuously cut and flip the materials, so that the materials are fully mixed on the horizontal layer of the mixing cylinder 1, and the preliminary uniform distribution of the materials in the horizontal direction is realized.

[0033] When the stirring shaft 5 rotates, the driving shell 13 and the driven bevel gears 113 connected with the flat paddle 10 synchronously move in a circular motion, the top end of the driving rod 111 is fixedly connected with the top cover 3, the driving rod 111 is fixedly not moving, the driving bevel gears 112 on the driving rod 111 are fixedly positioned, with the driving shell 13 driving the driven bevel gears 113 to move in a circular motion, the driven bevel gears 113 will rotate at the same time of moving in a circular motion due to the meshing of the driven bevel gears 113 and the fixed driving bevel gears 112, the two driven bevel gears 113 are symmetrically distributed, the rotation directions of the two driven bevel gears 113 are opposite, the driven bevel gears 113 are fixedly connected with the rotating shaft of the flat paddle 10, driving the flat paddle 10 to rotate, the rotating direction of the flat paddle 10 cooperates with the circular rotating direction of the stirring shaft 5, so that the material not only moves in a horizontal direction but also is turned in an up-down direction in the mixing cylinder 1. Under the synergistic effect of the horizontal stirring of the arc paddle 9 and the up-down stirring of the flat paddle 10, the material flows and mixes in all directions and multiple levels in the mixing cylinder 1, improving the mixing efficiency and uniformity.

[0034] In the process of the stirring shaft 5 driving the connecting rod 7 and the mounting rod 8 to rotate, the scraping and brushing assembly 12 synchronously operates, the first scraper 121 and the first brush plate 122 mounted on the mounting rod 8 and the second scraper 123 and the second brush plate 124 mounted on the connecting rod 7 move in a circular motion along the inner wall of the mixing cylinder 1 with the rotation of the overall structure, the first scraper 121 and the second scraper 123 first contact the large block of material attached to the inner wall of the mixing cylinder 1, scraping the large block of material from the inner wall so that it falls into the mixing cylinder 1 again to participate in the mixing; then, the first brush plate 122 and the second brush plate 124 clean the small material still remaining on the inner wall after scraping, ensuring that the remaining material is completely cleaned.

[0035] When the material in the mixing cylinder 1 is sufficiently stirred and mixed to reach the expected mixing quality, the speed reducer motor 62 is stopped, and the stirring shaft 5 and the related stirring parts stop rotating, at this time, the valve on the discharge pipe 2 is opened, and the mixed refractory material is discharged from the discharge pipe 2 under the action of gravity.

[0036] After the discharging is completed, the top cover 3 and the stirring shaft 5, the arc paddle 9, the flat paddle 10 and the scraping and brushing assembly below the top cover 3 can be taken out from the mixing cylinder 1 through the handle 31, so that the equipment can be maintained and repaired, and the next mixing operation can be prepared.
