DETAILED DESCRIPTION

[0017] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.

[0018] Example 1

[0019] like Figure 1As shown; a deironing device for preparing zinc sulfate, comprising a belt conveyor 1, a fixed frame 2, a rotating motor 3 and a deironing device 4, wherein the rotating motor 3 is mounted on the fixed frame 2 and the power rod is connected to the deironing device 4, and the deironing device 4 is arranged above the belt conveyor 1; the deironing device 4 comprises a glass fiber rotating plate 41, a rake device 44 and a lead-out device 45, the middle part of the glass fiber rotating plate 41 is connected to the rotating motor 3, and the glass fiber rotating plate 41 surrounds the rotating motor 3 A plurality of magnetic slots 42 are provided, and magnetic plates are arranged in the magnetic slots 42. A plurality of T-shaped rake slots 43 are evenly arranged on the glass fiber transfer plate 41 between the adjacent magnetic slots 42. The rake device 44 is connected to the T-shaped rake slot 43. One end of the guide device 45 is mounted on the fixed frame 2 and the other end is movably connected to the center of the glass fiber transfer plate 41. The rake device 44 includes a T-shaped rod 46, a rake rod 47 and a limit block 48. The plurality of rake rods 47 are connected to the T-shaped rod 4 6, one end of the T-shaped rod 46 is hinged in the T-shaped rake trough 43 and a torsion spring is connected at the connection. The limit block 48 is installed in the T-shaped rake trough 43 and is used to limit the T-shaped rod 46; the derivation device 45 includes a U-shaped guide channel 49, a conveying screw 410, a human-shaped dispersion block 412, a scraper 414, a connecting rod 416 and a motor. The conveying screw 410 is arranged in the U-shaped guide channel 49 and connected to the motor. The two ends of the U-shaped guide channel 49 are connected to the secondary The material baffle plate 413, the human-shaped dispersion block 412 is connected to the U-shaped material guide channel 49 through a plurality of connecting rods 416, and the upper end of the human-shaped dispersion block 412 is connected to the scraper 414; the inner wall of the U-shaped material guide channel 49 is symmetrically connected with a primary material baffle plate 411, and the lower end of the human-shaped dispersion block 412 is arranged between the primary material baffle plate 411 and the secondary material baffle plate 413; the human-shaped dispersion block 412 is provided with a middle arc-shaped material baffle groove 415 near the bottom of the conveying screw 410.

[0020] The glass fiber rotating plate 41 is driven to rotate by the rotating motor 3. During the rotation process, the magnetic plate on it absorbs the iron powder or iron slag in the conveyed material on the belt conveyor 1. At the same time, the T-bar 46 is in a vertical state under the action of the torsion spring and is limited and maintained by the limit block 48, so that the rake rod 47 on the T-bar 46 can rake the material. When the T-bar 46 collides with the material baffle on the belt conveyor 1, the T-bar 46 is retracted into the T-shaped rake trough 43. On the contrary, when no obstacle is encountered, the T-bar 46 is vertical under the action of the torsion spring; the scraper 414 contacts the rotating glass fiber rotating plate 41, and when it scrapes the magnetic plate, it scrapes out the iron powder or iron slag on it. The magnetic plate area causes the iron powder or iron slag to fall into the U-shaped guide channel 49, and then the motor drives the conveying screw 410 to convey the iron powder or iron slag out to complete the iron removal work. When the U-shaped guide channel 49 moves to the magnetic plate area again, the iron powder or iron slag is blocked by the first-level baffle plate 411, the second-level baffle plate 413 and the human-shaped dispersion block 412 to prevent it from being adsorbed onto the magnetic plate again. The first-level baffle plate 411 and the second-level baffle plate 413 need to be set at an angle, and a middle arc-shaped baffle groove 415 is set at the same time to make the iron powder or iron slag move toward the middle under the action of suction, so as to prevent the iron powder or iron slag from being concentrated on the edge of the baffle and being attracted to the magnetic plate.
