All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0026] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments may be combined with each other.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0028] As Figures 1-5 shown, this embodiment provides a magnetic separation device for producing pelletized iron concentrate powder, including a support frame 1. A magnetic separation mechanism 2 for magnetic separation of materials is arranged inside the support frame 1, and a crushing assembly 3 is arranged on one side of the magnetic separation mechanism 2.

[0029] The magnetic separation mechanism 2 includes a semi-circular frame 201, a cylinder 202, a round rod 203, a connecting rod 204, a magnetic system 205, a waste discharge groove 206, a mounting rod 207, a first motor 208, a support plate 209, a booster pump 210, a water inlet pipe 211, a drain pipe 212 and a spray head 213. The semi-circular frame 201 is arranged inside the support frame 1. The cylinder 202 is arranged inside the semi-circular frame 201. The round rod 203 is rotatably connected to the inner wall of the cylinder 202. The connecting rod 204 is fixedly connected to the outer wall of the round rod 203. The magnetic system 205 is fixedly connected to one end of the connecting rod 204. The waste discharge groove 206 is communicated and arranged at the bottom of the semi-circular frame 201. The mounting rod 207 is bolted to the outer wall of the cylinder 202. The first motor 208 is coaxially arranged at one end of the mounting rod 207. The support plate 209 is bolted to the side wall of the support frame 1. The booster pump 210 is bolted to the bottom of the support frame 1. The water inlet pipe 211 is fixedly connected to the output end of the booster pump 210. The drain pipe 212 is communicated and arranged at one end of the water inlet pipe 211. The spray head 213 is communicated and arranged on the outer wall of the drain pipe 212. One end of the mounting rod 207 sequentially penetrates through the semi-circular frame 201 and the support frame 1 and is rotatably connected to the semi-circular frame 201 and the support frame 1. One end of the round rod 203 extends to the outside of the cylinder 202 and is fixedly connected to the support frame 1. When in use, the first motor 208 drives the mounting rod 207 and the cylinder 202 to rotate. Since the round rod 203 is rotatably connected to the inside of the cylinder 202 and one end thereof is fixedly connected to the support frame 1, the magnetic system 205 will not be driven to rotate when the cylinder 202 rotates. When the pulp enters the inside of the semi-circular frame 201, the iron ore inside it will be adsorbed by the magnetic system 205, and the non-magnetic substances will enter the waste discharge groove 206 and then be discharged. Then, the booster pump 210 pumps the external water into the drain pipe 212 and then sprays it out from the spray head 213, so as to wash down the iron ore located on the outer wall of the cylinder 202. Repeating the above steps can achieve the effect of a large amount of magnetic separation.

[0030] As Figure 3 and Figure 5 shown, the crushing assembly 3 includes a frame body 301, a first crushing roller 302, a second crushing roller 303, a first gear 304, a second gear 305 and a second motor 306. The frame body 301 is bolted to the top of the semi-circular frame 201. The first crushing roller 302 and the second crushing roller 303 are both rotatably connected to the inside of the frame body 301. The first gear 304 and the second gear 305 are respectively fixedly connected to one end of the first crushing roller 302 and the second crushing roller 303. The second motor 306 is coaxially arranged on the side wall of the first gear 304. The first gear 304 meshes with the second gear 305. Before magnetic separation, the first crushing roller 302 and the second crushing roller 303 rotate, so as to crush the large particles in the pulp, thereby improving the magnetic separation effect.

[0031] As Figure 1As shown, a filter screen 4 for collecting iron ore is bolted to the inner wall of the support frame 1. The filter screen 4 is made of stainless steel. During use, the filter screen 4 can collect iron ore and prevent it from directly falling onto the ground.

[0032] As Figure 1 shown, a reinforcing rod 5 is bolted to the inner wall of the support frame 1. A stabilizing rod 6 is bolted to the side wall of the reinforcing rod 5, and the top of the stabilizing rod 6 is bolted to the bottom of the support plate 209. During use, the stabilizing rod 6 can provide support for the bottom of the support plate 209, thereby improving the stability when the first motor 208 operates.

[0033] As Figure 1 shown, a stabilizing plate 7 is bolted to the top of the support frame 1. The drain pipe 212 is located inside the stabilizing plate 7 and is fixedly connected to the stabilizing plate 7. During use, the stabilizing plate 7 can support the drain pipe 212, thereby improving the stability when the spray head 213 drains water.

[0034] As Figure 1 shown, a rectangular plate 8 is welded to the bottom of the support frame 1. Threaded holes 9 are formed in the top of the rectangular plate 8. The number of the threaded holes 9 is four and they are evenly distributed. During use, external bolts are sequentially screwed into the threaded holes 9 and the ground, so as to quickly fix the device and improve the stability during magnetic separation.

[0035] As Figure 1 shown, a guiding plate 10 for guiding iron concentrate is bolted to the top of the semi-circular frame 201. The guiding plate 10 is located above the filter screen 4. When the material, iron ore, is washed down by water, it will be guided by the guiding plate 10 onto the filter screen 4, thereby improving the stability during discharging.

[0036] Specifically, when this magnetic separation equipment for producing pellet iron concentrate is in use: Connect the first motor 208, the second motor 306, and the booster pump 210 to an external power source. Then the first motor 208 drives the mounting rod 207 and the cylinder 202 to rotate. Since the round rod 203 is rotatably connected to the inside of the cylinder 202 and one end of it is fixedly connected to the top of the support frame 1, the cylinder 202 will not drive the magnetic system 205 to rotate when it rotates. Then pour the pulp into the inside of the frame body 301. Then the second motor 306 drives the first crushing roller 302 and the second crushing roller 303 to crush the larger particles in the pulp. When the pulp enters the inside of the semi-circular frame 201, the iron ore inside it will be adsorbed by the magnetic system 205 and then driven to rotate by the cylinder 202. The non-magnetic substances will enter the waste discharge groove 206 and then be discharged. Then the booster pump 210 pumps external water into the drain pipe 212 and then sprays it out from the spray head 213, so as to wash down the iron ore on the outer wall of the cylinder 202, and then it is guided by the guiding plate 10 onto the filter screen 4, thus completing the magnetic separation.

[0037] All the technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
