[0025] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0026] Please see Figures 1-5 The present invention relates to a magnetic iron content analyzer for iron concentrate, comprising a housing 1, a crushing barrel 2, and a feed inlet 4. The crushing barrel 2 is fixedly located on the top of the housing 1 and communicates with the housing 1. The feed inlet 4 is located on one side of the top of the crushing barrel 2. A drive motor 3 is fixedly located at the center of the top of the crushing barrel 2. The output shaft of the drive motor 3 extends through the interior of the housing 1 and a striking rod 18 is fixedly located on its surface. Two upright plates 6 are fixedly located in the upper part of the housing 1. Magnetic plates 7 are symmetrically embedded in the two upright plates 6, and the magnetic poles between the two magnetic plates 7 are opposite. Guide plates 8 and anti-caking components are fixedly fixedly on the two upright plates 6.

[0027] The main body is the box body 1, and a crushing barrel 2 is set on the top of the box body 1. A drive motor 3 is installed on the crushing barrel 2, and a striking rod 18 is installed on the output shaft of the drive motor 3. First, the material enters from the feed inlet 4. Iron concentrate is added to the crushing bucket 2, and then the drive motor 3 is run, which drives the striking rod 18 to rotate to break up the iron concentrate. The iron concentrate then falls into the box 1, which is divided into upper and lower parts. The upper part consists of two vertical plates 6, on which magnetic plates 7 are symmetrically embedded. The magnetic poles of the two opposing magnetic plates 7 are opposite. A guide plate 8 is also installed on the vertical plate 6. The iron concentrate falls into the box 1 and moves to the left under the action of the guide plate 8. It first hits the left vertical plate 6 and the magnetic plate 7, which promotes dispersion and completes part of the magnetic separation. Then, under the action of the guide plate 8, it hits the right side and then the left side. Since the angle of the guide plate 8 remains unchanged, the iron concentrate hits the opposite vertical plate 6 or magnetic plate 7 at the same position, which will not knock off the magnetic iron adsorbed by the lower magnetic plate 7, and thus will not affect the measurement results. The iron concentrate is guided by the guide plate 8 to hit multiple times, which completes multiple magnetic separations. The sufficiency and accuracy of magnetic separation are improved through multiple magnetic separations.

[0028] The anti-caking component includes a hollow plate 11 and an air outlet 10. The hollow plate 11 is fixedly and alternately on the outer wall of the vertical plate 6, and the air outlet 10 is inclinedly opened inside the vertical plate 6, and the hollow plate 11 and the air outlet 10 are connected.

[0029] A hollow plate 11 is installed on the outer wall of the upright plate 6 and connected to the external pipeline to provide airflow. An air outlet 10 is provided on the upright plate 6 and connected to the hollow plate 11. The tilt angle of the air outlet 10 is consistent with the tilt angle of the guide plate 8. By controlling the emission of pulse airflow at the air outlet 10, the strong airflow impact energy can be used to more effectively break up stubborn agglomerates. At the same time, the wind formed by the airflow can ensure that the iron concentrate will fall near the magnetic plate 7 afterward, so that the magnetic force of the magnetic plate 7 is sufficient to attract the magnetic iron.

[0030] Each guide plate 8 is fixedly provided with a protrusion 9, and the protrusions 9 are staggered.

[0031] like Figure 4 As shown, several protrusions 9 are provided on the guide plate 8. The protrusions 9 are staggered and, together with the pulsed airflow, cause the clumps to break up.

[0032] A vibrator 12 is fixedly installed on the back of each guide plate 8.

[0033] like Figure 5 As shown, the vibrator 12 causes the guide plate 8 to vibrate, further enhancing the dispersing effect and making the subsequent adsorption effect better.

[0034] At least three magnetic plates 7 are embedded in each upright plate 6, and the magnetism of the magnetic plates 7 increases from top to bottom.

[0035] The magnetic plates 7 embedded in the vertical plate 6 adopt a gradient design with increasing magnetic strength from top to bottom. The core is to use magnetic gradient constraint to avoid excessive concentration of adsorption by the upper magnetic plate 7 due to indiscriminate adsorption, which may cause non-target powders such as refined iron powder to be trapped and reduce the separation accuracy. At the same time, each layer of magnetic plates 7 can adsorb impurities with corresponding magnetic strength according to its own magnetic strength, so as to achieve a uniform distribution of adsorption and improve the overall effect and accuracy of magnetic separation.

[0036] The lower part of the box 1 is provided with a collection box 14, and a pressure sensor 15 is fixedly installed at the bottom of the collection box 14, and the pressure sensor 15 is fixedly connected to the bottom of the inner cavity of the box 1.

[0037] The lower part of the chamber 1 contains a pressure sensor 15 and a collection box 14. The iron concentrate will eventually fall into the collection box 14. The pressure sensor 15 measures the weight, and the content of magnetic iron can be calculated.

[0038] The bottom of each of the two upright plates 6 is fixedly provided with a support plate 13, and the support plate 13 is fixedly connected to the left and right sides of the inner cavity of the box body 1.

[0039] The support plate 13 supports the upright plate 6 and prevents the powder from falling everywhere, ensuring that all the unadsorbed powder falls into the collection box 14.

[0040] The lower surface of the inner cavity of the crushing barrel 2 is a conical surface. A scraper 19 is fixedly provided at the bottom end of the output shaft of the drive motor 3, and the surface of the scraper 19 is in contact with the conical surface. The scraper 19 is used to scrape off the iron concentrate powder adhering to the inner wall of the crushing barrel 2.

[0041] The inner cavity of the crushing barrel 2 has a discharge port 17 corresponding to the cone of the cone surface. The top of the box body 1 has a feed port 5 that communicates with the discharge port 17. The feed port 5 is located directly above the uppermost guide plate 8. The surface of the box body 1 has a box door 16.

[0042] The cone-shaped part of the inner cavity of the crushing barrel 2 corresponds to the discharge port 17. The scraper 19 scrapes the iron concentrate adhering to the inner wall of the crushing barrel 2 and drops it into the discharge port 17. The iron concentrate falls into the box body 1 through the discharge port 17 and the inlet 5. The box door 16 on the surface of the box body 1 can be opened to facilitate sampling and cleaning.

[0043] When using this iron concentrate magnetic iron content analyzer: Iron concentrate is added into the crushing barrel 2 through the inlet 4. The drive motor 3 drives the striking rod 18 to break up the iron concentrate. Then, the iron concentrate falls into the box 1 through the outlet 17 and the inlet 5. At the same time, the drive scraper 19 scrapes the iron concentrate adhering to the inner wall of the crushing barrel 2 to the outlet 17. The iron concentrate falls into the box 1 and moves to the left under the action of the guide plate 8. It first hits the left vertical plate 6 and the magnetic plate 7, which promotes dispersion and completes part of the magnetic separation. Then, under the action of the guide plate 8, it hits the right side and then the left side, completing multiple times. Magnetic separation is performed, and the iron concentrate falls into the collection box 14. During the process, the hollow plate 11 is connected to the external pipeline. By controlling the emission of pulsed airflow at the air outlet 10, the strong airflow impact can more effectively break up stubborn agglomerates. At the same time, the wind generated by the airflow can ensure that the iron concentrate will fall near the magnetic plate 7 afterward, so that the magnetic force of the magnetic plate 7 is sufficient to attract the magnetic iron. The protrusion 9, together with the pulsed airflow, promotes the breaking up of agglomerates. The vibrator 12 causes the guide plate 8 to vibrate, further promoting the breaking up effect. After the iron concentrate falls into the collection box 14, it is weighed by the pressure sensor 15, and the content of magnetic iron can be obtained by calculation.

[0044] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
