Description

Technical Field

[0001] The present invention relates to the field of ore dressing equipment, and particularly to an iron-removing ore dressing machine. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain utilizable properties, and can be divided into metallic minerals and non-metallic minerals. The unit content of the useful component in the ore is called the ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are commonly expressed in percentages. The ore grade is commonly used to measure the value of the ore. However, the composition of gangue and the amount of harmful impurities in the ore with the same effective components also affect the ore value. When screening non-iron ores, an iron-removing ore dressing machine is generally used.

[0003] However, in the prior art, iron ore is generally adsorbed by a magnetic separation cylinder, and then the iron ore is scraped off by a scraper. Generally, the scraper is fixed in front of the magnetic separation cylinder. The magnetic separation cylinder rotates, and the scraper scrapes off the iron ore. This kind of material discharging method has certain defects: on the one hand, the magnetic force is large, and the scraper cannot smoothly scrape off the iron ore; on the other hand, due to the unsuccessful scraping, the ore is adsorbed on the surface of the magnetic separation cylinder, resulting in the subsequent ore not being selected by the magnetic separation cylinder. For this reason, we propose an iron-removing ore dressing machine. Summary of the Invention

[0004] The purpose of the present invention is to provide an iron-removing ore dressing machine.

[0005] The technical problems of the present invention are mainly solved by the following technical solutions:

[0006] An iron-removing ore dressing machine, comprising a box body:

[0007] A crushing mechanism, a dispersing mechanism, a magnetic separation mechanism and a collection mechanism are sequentially arranged in the box body from top to bottom;

[0008] The crushing mechanism includes two groups of crushing rollers driven by a motor I;

[0009] The dispersing mechanism includes a cylinder arranged directly below between the two groups of crushing rollers. An inlet opening is arranged at the top of the cylinder, and a blanking opening is arranged at one side of the bottom of the cylinder. A driving shaft driven by a motor II is also arranged in the cylinder. A plurality of groups of stirring rods are radially arranged on the outer wall of the driving shaft, and an electromagnet sleeve is sleeved on the stirring rod;

[0010] The magnetic separation mechanism includes an inclined plate. An electromagnetic iron plate is arranged at the bottom of the inclined plate, and a rotating shaft embedded in the side wall of the box body is arranged in the middle of the inclined plate;

[0011] Inlet and outlet openings are arranged on both side walls at the bottom of the box body. The collection mechanism includes aggregate boxes located on both sides at the bottom of the box body, and one end of the aggregate box passes through the inlet and outlet opening and extends into the box body.

[0012] Preferably, a bottom plate is arranged at the bottom inside the box body above the connection of the two aggregate boxes, wherein the bottom end of the inclined plate is closely attached to the top end surface of one end of the bottom plate, and the blanking opening is located directly above the top end of the inclined plate.

[0013] Preferably, a mounting shaft is longitudinally arranged inside the box body below the rotating shaft, wherein one end of the mounting shaft extends to the outside of the box body, and a driving block is radially arranged on the outer wall of the mounting shaft.

[0014] Preferably, baffles are inclined downward on both sides of the bottom of the cylinder body, wherein a V-shaped structure is formed between the two baffles, the baffles are located above the inclined plate, and the blanking opening is located between the two baffles.

[0015] Preferably, a bulging part protrudes outward from the top of the side wall of the cylinder body, a filter screen is arranged at the opening of the bulging part, and the bulging part is connected to an exhaust fan through a pipeline.

[0017] The beneficial effects of the present invention are as follows: After the material is crushed by the crushing mechanism of the present invention, the powder is dispersed by the dispersing mechanism for subsequent magnetic separation. At the same time, when the dispersing mechanism disperses the material, the iron material in the powder can be preliminarily magnetically separated by the electromagnetic iron sleeve. The dispersed powder falls on the magnetic separation mechanism and is magnetically separated by it and then flows into the corresponding collection box. After the magnetic separation is completed, the orientation of the inclined plate in the magnetic separation mechanism is changed, and at the same time, the electromagnetic iron plate and the electromagnetic iron sleeve are powered off, so that the iron material above the inclined plate and on the electromagnetic iron sleeve can flow into the other aggregate box, which is convenient for cleaning the magnetically separated iron material and can also classify and store the iron material and the powder.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following is through examples and in combination with the attached Figure 1, a further specific description of the technical solution of the present invention is provided.

[0021] A iron removal ore dressing machine, comprising a box body 1:

[0022] Inside the box body 1, a crushing mechanism 2, a dispersing mechanism 3, a magnetic separation mechanism 4 and a collection mechanism 5 are sequentially arranged from top to bottom;

[0023] The crushing mechanism 2 includes two groups of crushing rollers 21 driven by a motor I;

[0024] The dispersing mechanism 3 includes a cylinder body 31 arranged directly below the two groups of crushing rollers 21. An inlet opening 32 is arranged at the top of the cylinder body 31, and a blanking opening 33 is arranged at one side of the bottom of the cylinder body 31. A driving shaft 34 driven by a motor II is also arranged inside the cylinder body 31. A plurality of groups of stirring rods are radially arranged on the outer wall of the driving shaft 34, and an electromagnet sleeve 35 is sleeved on the stirring rods;

[0025] The magnetic separation mechanism 4 includes an inclined plate 41. An electromagnetic iron plate 42 is arranged at the bottom of the inclined plate 41, and a rotating shaft 43 embedded in the side wall of the box body 1 is arranged in the middle of the inclined plate 41;

[0026] Inlet and outlet openings 6 are arranged on both side walls at the bottom of the box body 1. The collection mechanism 5 includes aggregate bins 51 located on both sides at the bottom of the box body 1, and one end of the aggregate bin 51 passes through the inlet and outlet opening 6 and extends into the box body 1.

[0027] As Figure 1 shown, a bottom plate 7 is arranged at the bottom inside the box body 1 above the connection of the two groups of aggregate bins 51. The bottom end of the inclined plate 41 is closely attached to the top end surface of one end of the bottom plate 7, and the blanking opening 33 is located directly above the top end of the inclined plate 41.

[0028] As Figure 1 shown, an installation shaft 8 is longitudinally arranged inside the box body 1 below the rotating shaft 43. One end of the installation shaft 8 extends outside the box body 1, and a driving block 9 is radially arranged on the outer wall of the installation shaft 8.

[0029] As Figure 1 shown, baffles 10 are inclined downward on both sides at the bottom of the cylinder body 31. A group of inverted V-shaped structures are formed between the two groups of baffles 10. The baffles 10 are located above the inclined plate 41, and the blanking opening 33 is located between the two groups of baffles 10.

[0030] As Figure 1 shown, an arched portion 11 protrudes outward from the top of the side wall of the cylinder body 31. A filter screen is arranged at the opening of the arched portion 11, and the arched portion 11 is connected to a suction fan through a pipeline. The dust diffused inside the cylinder body 31 is extracted by the suction fan through the pipeline and the arched portion 11 to improve the working environment.

[0031] As Figure 1 shown, arc-shaped plates 12 are provided in the box body 1 on both sides of the feeding opening 32. The crushing roller 21 is located between the two groups of arc-shaped plates 12, and a feeding hopper 13 is provided at the top of the box body 1 between the tops of the two groups of arc-shaped plates 12.

[0032] The working principle of the present invention: Ore is introduced into the crushing mechanism 2 and crushed by the crushing roller 21. The crushed ore material enters the cylinder body 31 through the feeding opening 32. At this time, the motor II drives the driving shaft 34 to drive a plurality of stirring rods and the electromagnet sleeve 35 to stir the ore material in the cylinder body 31, so as to disperse the crushed ore material for subsequent magnetic separation. At the same time, the electromagnet sleeve 35 can also perform preliminary magnetic separation on the iron ore material inside while dispersing the ore material;

[0033] The dispersed ore material falls on the inclined plate 41 through the blanking opening 33 and flows down along its inclined surface. During the flowing process of the ore material, the electromagnetic iron plate 42 works to adsorb the iron material on the top surface of the inclined plate 41. The ore material after magnetic separation flows into the left collecting box 51 through the top surface of the inclined plate 41 for collection and treatment;

[0034] During the above process, the mounting shaft 8 is screwed into the screw hole on the side wall of the box body 1. In order to fix the inclined state of the inclined plate 41, when the mounting shaft 8 is rotated to rotate in the screw hole, it drives the driving block 9 to abut against the right bottom end of the inclined plate 41 so that the inclined plate 41 is in a state of being lower on the left and higher on the right. After the processing is completed, the mounting shaft 8 is rotated to drive the driving block 9 to rotate clockwise, so that the driving block 9 jacks up the inclined plate 41 on the left side of the rotating shaft 43 to change its inclined state, so that the inclined plate 41 is in a state of being higher on the left and lower on the right. Then, at this time, the electromagnetic iron plate 42 is powered off, and the iron material above the inclined plate 41 will flow along its inclined surface into the collecting box 51 on the right side under the condition of losing magnetic attraction. At the same time, the electromagnet sleeve 35 is powered off so that the adsorbed iron material drops and is affected by the stirring of the stirring rod and falls on the inclined plate 41 through the blanking opening 33, and finally all flow into the collecting box 51 on the right side, which is convenient for cleaning and collecting the magnetic iron material, and can also facilitate the classification and storage of the ore material and the iron material.

[0035] The above has described the present invention in detail, but the above content is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
