Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 The present invention provides a technical solution: a high-efficiency continuous mixing reaction device for synthesizing ferromanganese phosphate, comprising a crushing mechanism and a mixing mechanism, wherein the crushing mechanism is arranged above the mixing mechanism, such as Figure 3 As shown, the crushing mechanism includes a crushing barrel 1, and a plurality of crushing rollers 2 are arranged inside the crushing barrel 1. Two crushing rollers 2 are symmetrically rotated in a group and arranged inside the crushing barrel 1. Three groups of crushing rollers 2 are arranged inside the crushing barrel 1. The material is injected from the top of the crushing barrel 1 and is squeezed between the two crushing rollers 2 to achieve a crushing effect. Figure 2 As shown, the side walls of the crushing barrel 1 are respectively provided with strip-shaped through-slots 3 at both ends corresponding to the crushing roller 2. The strip-shaped through-slots 3 are arranged horizontally. The outside of the crushing barrel 1 is provided with a movable block 4 corresponding to the crushing roller 2. The crushing roller 2 passes through the strip-shaped through-slot 3 at one end and is rotatably connected to the movable block 4. The outside of the crushing barrel 1 is provided with a driving screw 5 for driving the movable block 4 to slide. By rotating the driving screw 5, the position of the movable blocks 4 at both ends is adjusted under the action of the threaded fit, so that it can be flexibly adjusted according to the particle size of the material.

[0023] Specifically, if Figure 4 The movable block 4 is provided with a movable groove 6, and the movable groove 6 is movably provided with an adjusting block 7. The driving screw 5 passes through the adjusting block 7 and is screwed with the adjusting block 7. An elastic element is provided between the adjusting block 7 and the corresponding movable groove 6. The outer surface of the crushing barrel 1 is provided with connecting plates 8 at both ends corresponding to the driving screw 5. The two ends of the driving screw 5 are rotatably set on the surface of the connecting plate 8. A slider can be provided on the outer wall of the adjusting block 7, and a sliding groove matching the slider is provided on the inner wall of the movable groove 6. The elastic element is a spring. Under the action of the elastic element, the adjusting block 7 tends to move away from each other, and the threads at both ends of the driving screw 5 are set in opposite directions. By rotating the driving screw 5, the adjusting block 7 can be controlled to move in the opposite direction under the action of the thread cooperation. The adjusting block 7 drives the movable block 4 to move through the elastic element, and the crushing roller 2 is driven by the movable block 4. The crushing effect is adjusted by adjusting the pre-tightening force of the elastic element. At the same time, the movable block 4 can slide relative to the driving screw 5 to play a certain buffering role.

[0024] Specifically, if Figure 2As shown, a rectangular groove 9 is provided on the outer surface of the crushing barrel 1 at a side of the strip groove 3 away from the adjustment block 7. A transmission block 10 is movably provided inside the rectangular groove 9. A driving sleeve 11 is rotatably provided inside the transmission block 10. The driving sleeve 11 is coaxially connected to a first bevel gear 12. Figure 4 As shown, the first bevel gear 12 is located inside the transmission block 10, and the crushing roller 2 is coaxially connected to the second bevel gear 13. The crushing roller 2 is rotatably set on the transmission block 10, and the first bevel gear 12 is meshed with the second bevel gear 13. The outer surface of the crushing barrel 1 is rotatably provided with a transmission rod 14, and the transmission rod 14 passes through the driving sleeve 11. The outer surface of the crushing barrel 1 is provided with connecting plates 15 at both ends of the transmission rod 14 corresponding to the outer surface of the crushing barrel 1. The surface of the connecting plate 15 is fixedly connected to a driving motor 16 for driving the transmission rod 14 to rotate. The outer wall of the transmission rod 14 is provided with a limiting groove extending in the same direction, and the inner wall of the driving sleeve 11 is provided with a limiting block matching the limiting groove. The driving motor 16 drives the transmission rod 14 to rotate. Under the action of the limiting groove and the limiting block, the driving sleeve 11 rotates, and under the action of the first bevel gear 12 and the second bevel gear 13, the crushing roller 2 is driven to rotate. Since the driving sleeve 11 can slide along the transmission rod 14, no interference will be generated when adjusting the crushing roller 2.

[0025] Specifically, the mixing mechanism includes a mixing barrel 17 fixedly connected to the bottom of the crushing barrel 1, such as Figure 3 As shown, the lower side wall of the mixing barrel 17 is provided with a circular groove 18, and a rotating plate 19 is provided inside the circular groove 18 for rotation.

The outer surface of the housing 21 is provided with a motor 24 for driving the rotating plate 19. The motor 24 is used to drive the rotating plate 19 to rotate. The rotating plate 19 drives the stirring rod 20 to rotate inside the mixing barrel 17. Under the action of the transmission gear 23 and the internal gear 22, the stirring rod 20 rotates while rotating as the rotating plate 19 rotates, so as to fully stir the crushed material inside the mixing barrel 17.

[0026] Specifically, the outer wall of the stirring rod 20 is connected to the stirring blades 26 through a plurality of connecting rods 25. Figure 3 As shown, the stirring rod 20 rotates, driving the stirring blade 26 to rotate through the connecting rod 25, thereby achieving a sufficient stirring effect;

[0027] Specifically, the inner wall of the mixing barrel 17 is provided with a spiral blade 27, such as Figure 3 As shown, when the spiral blades 27 rotate inside the mixing barrel 17, the material at the bottom of the mixing barrel 17 moves upward under the action of the spiral blades 27, thereby achieving cyclic stirring of the material;

[0028] Specifically, the rotating plate 19 is coaxially connected to a rotating column 28. Since the spiral blades 27 are attached to the inner wall of the mixing barrel 17, the rotating column 28 is provided to form an annular cavity inside the mixing barrel 17, thereby improving the material conveying effect and preventing material accumulation. A rotating ring 29 is rotatably provided at the upper end of the interior of the mixing barrel 17. The rotating ring 29 is fixedly connected to the spiral blades 27, so that the motor 24 can drive the spiral blades 27 to rotate.

[0029] The lower side wall of the mixing barrel 17 is provided with a discharge port (not shown in the figure).

[0030] When the present invention is in use, the screw 5 is driven by rotation, and the adjusting block 7 is controlled to move in the opposite direction under the action of the thread cooperation. The adjusting block 7 drives the movable block 4 to move through the elastic element, and the movable block 4 drives the crushing roller 2. By adjusting the pre-tightening force of the elastic element, the crushing effect is adjusted. The driving motor 16 drives the transmission rod 14 to rotate. Under the action of the limit groove and the limit block, the driving sleeve 11 rotates. Under the action of the first bevel gear 12 and the second bevel gear 13, the crushing roller 2 is driven to rotate. The material is fed from the top of the crushing barrel 1 and is squeezed and crushed under the action of the crushing roller 2. The crushed material enters the interior of the mixing barrel 17. The motor 24 drives the rotating plate 19 to rotate. The rotating plate 19 drives the stirring rod 20 to rotate inside the mixing barrel 17. Under the action of the transmission gear 23 and the internal gear 22, the stirring rod 20 rotates while rotating as the rotating plate 19 rotates, so as to fully stir the crushed material inside the mixing barrel 17, synchronously driving the rotating ring 29 to rotate, and the rotating ring 29 drives the spiral fan blades 27 to rotate, thereby realizing cyclic stirring of the material.
