DETAILED DESCRIPTION

[0019] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 3 The utility model provides a technical solution: a raw material impurity removal device for magnesium hydroxide production, comprising: a frame 2; a screening component 3, the screening component 3 comprising a guard plate 301, the guard plate 301 is symmetrically fixedly installed in the middle of the frame 2, a slide groove 304 is opened in the middle of the guard plate 301, the guard plates 301 are symmetrically fixedly installed on the sides close to each other, rollers 3015 are symmetrically arranged in the guide rails 302, the rollers 3015 are fixedly installed with mounting shafts 3014 on the sides close to each other, and the mounting shafts 3014 are rotatably installed with connecting plates 3013 at one end away from the rollers 3015, the same side connecting plates 3013 are fixedly installed with sieve plates 303 on the sides close to each other, and a plurality of evenly distributed electromagnets 3012 are installed on the top of the lower sieve plate 303, and sliders 3010 are fixedly installed on the surfaces of the upper front and lower rear connecting plates 3013, and the sliders 3010 are slidably installed In the same side chute 304, a driving mechanism is provided in the screening component 3. By controlling the driving mechanism, the slider 3010 can be reciprocated in the chute 304, and then the connecting plate 3013 cooperates with the installation shaft 3014 and the roller 3015 to realize the reciprocating movement of the screen plate 303 in the guide rail 302, and the two screen plates 303 can move back and forth alternately, so that the initially crushed magnesium hydroxide raw material can be screened multiple times. Since the filter holes on the upper screen plate 303 are larger than the filter holes on the lower screen plate 303, the screening accuracy of the magnesium hydroxide raw material can be improved. In addition, an electromagnet 3012 is installed on the surface of the lower screen plate 303, which can adsorb the iron ore in the magnesium hydroxide raw material, further improving the screening accuracy of the magnesium hydroxide raw material. The screened magnesium hydroxide raw material will fall into the storage box 6 at the bottom of the frame 2, and the slag and iron ore will fall into the slag collection box 5.

[0021] A slag collection box 5 is provided at the lower part of one side of the frame 2, a storage box 6 is installed in the middle part of the frame 2, a feed hopper 1 is fixedly installed at the upper part of the other side of the frame 2, and a spring 3011 is fixedly installed in the middle part of the other side of the slider 3010. The spring 3011 is fixedly installed at one end away from the slider 3010 in the middle part of the same side slide groove 304 close to the feed hopper 1. By setting the spring 3011, the set spring 3011 can provide a thrust to the slider 3010 when opening, which is conducive to the opening of the mechanism. After the mechanism is opened, the spring 3011 is still in a compressed state, which can prevent the slider 3010 from accidentally sliding and ensure the stability of the mechanism after opening. A T-shaped plate 305 is fixedly installed on the side of the slider 3010 away from the screen plate 303, and a slot 308 is opened in the lower middle part of the T-shaped plate 305. The driving mechanism includes The fixed plate 4 is fixedly installed in the middle of the front and rear sides of the frame 2, and a stepper motor 306 is fixedly installed in the middle of the fixed plate 4. A connecting rod 307 is fixedly installed at the driving end of the stepper motor 306. A moving block 309 is rotatably installed at one end of the connecting rod 307 away from the stepper motor 306, and the moving blocks 309 are slidably installed in the slots 308 on the same side. By controlling the stepper motor 306, the stepper motor 306 can drive the connecting rod 307 to rotate, so that the moving block 309 can reciprocate in the slot 308. When the moving block 309 reciprocates in the slot 308, the T-shaped plate 305 can drive the slider 3010 to reciprocate in the slide groove 304, so that the screen plate 303 can reciprocate, and then the magnesium hydroxide raw material on the surface of the screen plate 303 can be screened and impurities removed.

[0022] In actual use, the magnesium hydroxide raw material after the initial crushing is transported to the feed hopper 1 through external transportation equipment. At this time, the staff controls the stepper motor 306 in the driving mechanism. The stepper motor 306 cooperates with the connecting rod 307, the moving block 309 and the notch 308 to realize the reciprocating movement of the T-shaped plate 305 and the slider 3010 along the slide 304, and then the two sieve plates 303 can move back and forth alternately, so as to screen and remove impurities from the magnesium hydroxide raw material on the surface of the sieve plate 303, and the filter holes on the surface of the lower sieve plate 303 are smaller than the filter holes on the surface of the upper sieve plate 303, so that the magnesium hydroxide raw material can be screened multiple times. Then, the staff controls the electromagnet 3012 on the lower sieve plate 303 through an external controller. At this time, the electromagnet 3012 can adsorb the iron ore in the magnesium hydroxide raw material due to its own magnetism. After screening is completed, the slag and iron ore impurities will fall into the slag collection box 5, and the screened magnesium hydroxide powder will fall into the storage box 6.
