[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Depend on Figure 1-Figure 6 The utility model relates to a magnetic iron removal device for tea leaves, comprising a shell 1, on which a feed port 2 and a discharge port 3 are respectively arranged, and the inner wall of the shell 1 is respectively fixedly provided with a main electromagnet 4 and an auxiliary electromagnet 5 along its circumference, and the main electromagnet 4 and the auxiliary electromagnet 5 are alternately arranged; a bracket 6 is fixedly provided inside the shell 1, a connecting cylinder 7 is fixedly provided on the bracket 6, an air duct 8 is provided on the connecting cylinder 7, and a dividing hopper 9 is fixedly provided on the air duct 8, wherein the air duct 8 is provided with a plurality of groups of blowing holes 10 and an inner cavity 11, a connecting groove 12 is provided inside the bracket 6, a fan 13 is fixedly provided on the shell 1, the plurality of groups of blowing holes 10 are all connected with the inner cavity 11, and the inner cavity 11 is connected with one end of the fan 13 through the connecting cylinder 7, the connecting groove 12 and the conduit in sequence;

[0026] The design is such that, when in use, tea leaves are put into the shell 1 through the feed port 2, and the tea leaves are dispersed and fall down through the dividing hopper 9, while the main electromagnet 4, the auxiliary electromagnet 5 and the fan 13 are operated, and wind is generated by the fan 13. The wind enters the inner cavity 11 through the conduit, the connecting groove 12 and the connecting cylinder 7 in sequence, and then is ejected through the multiple groups of blowing holes 10, so that the falling tea leaves are blown close to the auxiliary electromagnet 5 and the main electromagnet 4, and the auxiliary electromagnet 5 and the main electromagnet 4 magnetically adsorb the iron substances that may be contained in the tea leaves, so that the iron substances are magnetically adsorbed and fixed on the surfaces of the auxiliary electromagnet 5 and the main electromagnet 4, and the tea leaves continue to fall and are discharged through the discharge port 3, so as to realize the magnetic iron removal operation of the tea leaves; when the iron impurities accumulate more, the falling of the tea leaves can be stopped, and then the main electromagnet 4 and the auxiliary electromagnet 5 are powered off to make the magnetism disappear, so that the iron impurities can be discharged through the discharge port 3 after falling.

[0027] Specifically, the height direction of the auxiliary electromagnet 5 is vertically arranged relative to the upper surface of the shell 1, and the extension line of the length direction of the auxiliary electromagnet 5 does not coincide with the central axis of the shell 1; with this design, after the tea leaves are blown, most of the tea leaves will first contact with the tilted auxiliary electromagnet 5, and then contact with the main electromagnet 4, so that the iron impurities in the tea leaves are closer to the main electromagnet 4 or the auxiliary electromagnet 5, so as to further improve the impurity removal effect.

[0028] Specifically, the distribution hopper 9 is conical in shape, and the conical portion of the distribution hopper 9 is close to the feed inlet 2 , and the radius of the end of the distribution hopper 9 away from the feed inlet 2 is greater than the radius of the air duct 8 .

[0029] Specifically, the air duct 8 and the connecting tube 7 are rotatably matched, and a mounting frame 14 is fixedly provided on one end of the air duct 8 placed on the connecting tube 7, a rotating rod 15 is fixedly provided on the mounting frame 14, and a blade wheel 16 is fixedly provided on the rotating rod 15; such a design can make the blade wheel 16 drive the rotating rod 15 to rotate through the impact of the airflow, and the rotating rod 15 drives the air duct 8 to rotate through the mounting frame 14, so that the blowing holes 10 on the rotated air duct 8 can blow on the tea leaves after rotation, so that the tea leaves are blown in all directions and then approach the inner wall of the shell 1, thereby improving the magnetic attraction effect by reducing the distance.

[0030] Specifically, a partition 17 is fixedly provided inside the connecting tube 7, and a through hole 18 is formed in the middle of the partition 17. The through hole 18 is located below the blade wheel 16. The through hole 18 is truncated cone-shaped, and the top aperture size of the through hole 18 is smaller than the bottom aperture size of the through hole 18. Such a design can accelerate the airflow through the through hole 18 to increase the impact force of the airflow on the blade wheel 16.

[0031] Specifically, an outer annular groove 19 is formed at the bottom end of the air duct 8 , and an inner circular hole 20 is formed at the top end of the connecting tube 7 . The outer annular groove 19 and the inner circular hole 20 are rotatably matched.

[0032] Specifically, a plurality of air collecting frames 21 are fixedly provided on the outer wall of the air duct 8, and the air collecting frames 21 are covered on the outer sides of the corresponding air blowing holes 10; such a design can make the blown airflow more concentrated to ensure the blowing force of the airflow.
