DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0022] Reference Figure 1-4 , an ultra-fine phosphate rock powder crushing device, comprising a barrel body 1, a first rotating shaft 101 is rotatably connected to the top of the barrel body 1, a rotating column 102 is fixedly connected to the side wall of the first rotating shaft 101 inside the barrel body 1, and further comprising:

[0023] The inner wall of the barrel body 1 is slidably connected to the filter plate 2, a plurality of springs 201 are fixedly connected between the bottom of the filter plate 2 and the inner wall of the barrel body 1, a surrounding plate 202 is fixedly connected to the top of the filter plate 2, and the surrounding plate 202 fits the inner wall of the barrel body 1, a circular plate 203 is fixedly connected to the top of the surrounding plate 202, and the rotating column 102 can collide with the circular plate 203;

[0024] A crushing box 204 is fixedly connected to the bottom of the barrel 1, and the inner wall of the crushing box 204 is rotatably connected to the second rotating shaft 205 and the third rotating shaft 206 respectively, and the side walls of the second rotating shaft 205 and the third rotating shaft 206 are fixedly connected to the rolling roller 207;

[0025] It should be noted that: the phosphorus-containing ore is placed in the inner cavity of the barrel 1, and then the first rotating shaft 101 is driven to rotate, and the first rotating shaft 101 drives the rotating column 102 to rotate, so that the ore is initially crushed and screened, wherein the metal impurities such as iron and magnesium in the ore cannot be crushed, and the phosphorus-containing ore will be crushed, and then screened from the filter plate 2 to the inner cavity of the crushing box 204, and the second rotating shaft 205 and the third rotating shaft 206 in the crushing box 204 will drive the rolling roller 207 on its side wall to perform screening. The ore is further crushed by rotating the column 102. In the process of crushing the ore, the rotating column 102 will collide with the circular plate 203. In the process of collision, the circular plate 203 will drive the filter plate 2 to move downward through the enclosure 202. At this time, the spring 201 located between the filter plate 2 and the inner wall of the barrel 1 will be squeezed, and the spring 201 will generate a rebound force, thereby causing the filter plate 2 to vibrate up and down, which can not only enhance the screening effect, but also prevent the ore fragments from blocking the filter holes in the filter plate 2, thereby reducing the filtration efficiency of the filter plate 2.

[0026] Reference Figure 1-4 The first gear 3 is fixedly connected to the side wall of the second rotating shaft 205 located outside the crushing box 204, and the second gear 301 is fixedly connected to the side wall of the third rotating shaft 206 located outside the crushing box 204, and the second gear 301 is meshedly connected with the first gear 3;

[0027] The inner wall of the crushing box 204 is respectively fixedly connected with a first side plate 302 and a second side plate 303, and the first side plate 302 and the second side plate 303 are both inclined toward the middle of the crushing box 204;

[0028] It should be noted that: since the first gear 3 on the side wall of the second rotating shaft 205 and the second gear 301 on the side wall of the third rotating shaft 206 are meshingly connected, the rotation directions of the second rotating shaft 205 and the third rotating shaft 206 are opposite, and thus the rotation directions of the crushing rollers 207 on their side walls are opposite, thereby enhancing the crushing effect, and the ore screened from the inner cavity of the barrel body 1 will fall on the first side plate 302. Due to the inclined setting of the first side plate 302, the ore will fall between the crushing rollers 207, thereby enhancing the crushing rate, and the crushed ore will fall on the second side plate 303, so as to be discharged from the crushing box 204.

[0029] Reference Figure 1-4 The bottom of the filter plate 2 is fixedly connected with a connecting column 304, the bottom end of the connecting column 304 is fixedly connected with a pressing plate 305, and the top of the pressing plate 305 is inclined;

[0030] A first servo motor 306 is fixedly connected to the top of the barrel body 1, and the first servo motor 306 is fixedly connected to the first rotating shaft 101. A second servo motor 307 is fixedly connected to the side wall of the crushing box 204, and the second servo motor 307 is fixedly connected to the second rotating shaft 205.

[0031] It should be noted that the first servo motor 306 provides power for the rotation of the first rotating shaft 101 and the rotating column 102. Similarly, the second servo motor 307 provides power for the rolling roller 207 that crushes the ore. In the process of the filter plate 2 vibrating up and down, the connecting column 304 at the bottom thereof drives the pressure plate 305 to vibrate up and down, thereby accelerating the speed at which the ore slides on the first side plate 302 and accelerating the rolling speed of the rolling roller 207.

[0032] Operation method: Put the phosphorus-containing ore into the inner cavity of the barrel body 1, and drive the first rotating shaft 101 to rotate through the first servo motor 306. The first rotating shaft 101 will drive the rotating column 102 to rotate, so as to preliminarily crush the ore and screen it. Among them, the metal impurities containing iron, magnesium and other impurities in the ore cannot be crushed, and the ore containing phosphorus will be crushed, so as to be screened from the filter plate 2 to the inner cavity of the crushing box 204. In the process of crushing the ore, the rotating column 102 will also collide with the circular plate 203. In the process of collision, the circular plate 203 will drive the filter plate 2 to move downward through the enclosure 202. At this time, the spring 201 located between the filter plate 2 and the inner wall of the barrel body 1 will be squeezed, and the spring 201 will generate a rebound force, thereby causing the filter plate 2 to vibrate up and down, which can not only enhance the screening effect, but also prevent the ore fragments from blocking the filter holes in the filter plate 2, thereby reducing the filtering efficiency of the filter plate 2.

[0033] The ore is screened from the filter plate 2 into the inner cavity of the crushing box 204, driving the second servo motor 307, and the second servo motor 307 drives the second rotating shaft 205 to rotate. Since the first gear 3 on the side wall of the second rotating shaft 205 and the second gear 301 on the side wall of the third rotating shaft 206 are meshed and connected, the second rotating shaft 205 and the third rotating shaft 206 rotate in opposite directions, so that the rolling roller 207 on its side wall rotates in opposite directions, thereby enhancing the rolling effect, wherein the ore screened from the inner cavity of the barrel body 1 will fall on the first side plate 302, and due to the inclined setting of the first side plate 302, the ore will fall between the rolling rollers 207, thereby enhancing the rolling rate, and in the process of the filter plate 2 vibrating up and down, the connecting column 304 at the bottom thereof will drive the pressing plate 305 to vibrate up and down, thereby accelerating the sliding speed of the ore on the first side plate 302, and accelerating the rolling speed of the rolling roller 207, and the ore after rolling will fall on the second side plate 303, so as to be discharged from the crushing box 204.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
