Description

Technical Field

[0001] This utility model relates to the field of magnetic separator technology, and in particular to a multi-stage magnetic separator for zirconium-titanium ore. Background Technology

[0002] In the field of zirconium-titanium ore beneficiation, magnetic separation is a key process for removing magnetic impurities (such as magnetite, hematite, ilmenite and associated magnetic minerals) from raw materials. Its core requirement is to improve the purity of zirconium-titanium ore concentrate through efficient magnetic separation in order to meet the requirements of subsequent smelting and processing for raw material quality.

[0003] Some existing magnetic separators use static feeding or a single conveying structure, resulting in short residence time and uneven distribution of raw materials in the magnetic separation area. This leads to insufficient contact between the raw materials and the magnetic field, and incomplete removal of magnetic impurities. At the same time, if impurities adsorbed on the surface of the magnetic field are not cleaned in time, they will gradually accumulate and form a "magnetic shield," reducing the efficiency of subsequent magnetic separation. This requires frequent shutdowns for cleaning, affecting the overall production progress.

[0004] Therefore, a multi-stage magnetic separation device for zirconium-titanium ore is provided to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose a multi-stage magnetic separation device for zirconium-titanium ore.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A multi-stage magnetic separation device for zirconium-titanium ore includes a magnetic separation box, a feed hopper mounted on the magnetic separation box, and a slag outlet and a discharge outlet at the bottom, and further includes: A primary conveyor belt is installed inside the magnetic separator and is used to receive zirconium-titanium ore falling from the feed hopper. A secondary conveyor belt is installed inside the magnetic separator and is located below the primary conveyor belt to transport the zirconium-titanium ore that has undergone the initial magnetic separation. Two sets of magnetic separators are installed at the discharge end of the primary conveyor belt and the discharge end of the secondary conveyor belt, respectively. The upper magnetic separator is used to perform primary magnetic separation on the zirconium-titanium ore falling from the primary conveyor belt, and the lower magnetic separator is used to perform secondary magnetic separation on the zirconium-titanium ore falling from the secondary conveyor belt. Zirconium-titanium ore is transported into the magnetic separator via a primary conveyor belt. It undergoes initial magnetic separation via an upper magnetic separator. The ore that has passed the initial magnetic separation falls onto a secondary conveyor belt and then undergoes secondary magnetic separation via a lower magnetic separator. The ore that has passed the magnetic separation is discharged through the discharge port, while the remaining impurities are discharged through the slag discharge port.

[0007] Preferably, the magnetic separator includes a conical barrel, an electromagnet outer wall, a scraper, and a motor. Multiple sets of electromagnet outer walls are installed at equal intervals on the outer wall of the conical barrel to form a complete conical outer wall. The scraper is fixedly connected to the inner wall of the magnetic separator and is in contact with the electromagnet outer wall. The motor is fixedly connected inside the magnetic separator, and the output end of the motor is fixedly connected to the conical barrel. The motor causes the conical barrel to rotate, thereby causing the zirconium-titanium ore falling on the conveyor belt to come into contact with the electromagnet outer wall. Then, the magnetic impurities are attracted by the energized and magnetic electromagnet outer wall and rotated to the scraper in another direction. At this time, the electromagnet outer wall is de-energized, and the magnetic impurities are scraped off by the scraper.

[0008] Preferably, the magnetic separator is fixedly connected with connecting rod one, connecting rod two, and connecting rod three. The scraper is fixedly connected to connecting rod one, the conical barrel is rotatably connected to connecting rod two, and a protective cover is fixedly connected to connecting rod three, which is then attached to the motor.

[0009] Preferably, the magnetic separator is equipped with a feeding conveyor belt above the feed hopper, which is used to transport zirconium-titanium ore into the feed hopper. The magnetic separator is equipped with a slag discharge conveyor belt at the bottom, which is used to catch magnetic impurities falling from the magnetic separator and discharge the impurities through the slag discharge port.

[0010] Preferably, the magnetic separator is equipped with an inclined baffle plate below the feed hopper, and the magnetic separator is equipped with a discharge plate at the discharge end of the secondary conveyor belt, with the discharge end of the discharge plate facing the discharge port.

[0011] Preferably, the magnetic separator is equipped with a receiving box and a slag storage box at the slag outlet and the material outlet, respectively.

[0012] Preferably, the second connecting rod has a triangular wall to prevent impurities from accumulating on it.

[0013] Compared with the prior art, this utility model provides a multi-stage magnetic separation device for zirconium-titanium ore, which has the following beneficial effects: This invention utilizes a conveyor belt for even material distribution, a conical drum for magnetic rotation, and a fixed-point power-off scraping structure to prevent raw material accumulation and impurities from being "magnetically shielded," thereby reducing jamming and ensuring long-term equipment operation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example:

[0018] Reference Figure 1-5 A multi-stage magnetic separation device for zirconium-titanium ore includes a magnetic separation box 1, a feed hopper 101 mounted on the magnetic separation box 1, and a slag outlet 102 and a discharge outlet 103 at the bottom. It also includes: a primary conveyor belt 202 installed inside the magnetic separation box 1, used to receive the zirconium-titanium ore falling from the feed hopper 101; a secondary conveyor belt 203 installed inside the magnetic separation box 1, located below the primary conveyor belt 202, for conveying the zirconium-titanium ore after the initial magnetic separation; and two sets of magnetic separation devices, respectively installed at the discharge end of the primary conveyor belt 202 and the discharge end of the secondary conveyor belt 203. The magnetic separator located above is used for the initial magnetic separation of zirconium-titanium ore falling from the primary conveyor belt 202, and the magnetic separator located below is used for the secondary magnetic separation of zirconium-titanium ore falling from the secondary conveyor belt 203. The zirconium-titanium ore entering the magnetic separator box 1 is conveyed by the primary conveyor belt 202, and after the initial magnetic separation by the magnetic separator located above, the zirconium-titanium ore falls onto the secondary conveyor belt 203, and then undergoes secondary magnetic separation by the magnetic separator located below. At this time, the zirconium-titanium ore that has undergone magnetic separation will be discharged through the discharge port 103, while the remaining impurities from the magnetic separation will be discharged through the slag discharge port 102.

[0019] The magnetic separator includes a conical barrel 3, an electromagnet outer wall 4, a scraper 5, and a motor 6. Multiple sets of electromagnet outer walls 4 are installed at equal intervals on the outer wall of the conical barrel 3 to form a complete conical outer wall. The scraper 5 is fixedly connected to the inner wall of the magnetic separator 1, and the scraper 5 is in contact with the electromagnet outer wall 4. The motor 6 is fixedly connected inside the magnetic separator 1, and the output end of the motor 6 is fixedly connected to the conical barrel 3. The motor 6 causes the conical barrel 3 to rotate, thereby causing the zirconium-titanium ore falling on the conveyor belt to come into contact with the electromagnet outer wall 4. Then, the magnetic impurities are attracted by the energized and magnetic electromagnet outer wall 4 and rotated to the scraper 5 in another direction. At this time, the electromagnet outer wall 4 is de-energized, and the magnetic impurities are scraped off by the scraper 5.

[0020] The magnetic separator 1 is fixedly connected with connecting rod 1 701, connecting rod 2 702 and connecting rod 3 704. The scraper 5 is fixedly connected to connecting rod 1 701. The conical barrel 3 is rotatably connected to connecting rod 2 702. A protective cover 705 is fixedly connected to connecting rod 3 704. The protective cover 705 covers the motor 6.

[0021] The magnetic separator 1 has a feeding conveyor belt 201 installed above the feed hopper 101. The feeding conveyor belt 201 is used to transport zirconium titanium ore into the feed hopper 101. The bottom of the magnetic separator 1 has a slag discharge conveyor belt 204 installed. The slag discharge conveyor belt 204 is used to receive magnetic impurities falling from the magnetic separator and discharge the impurities through the slag discharge port 102. The magnetic separator 1 has an inclined baffle plate 104 installed below the feed hopper 101. The magnetic separator 1 has a discharge plate 105 installed at the discharge end of the secondary conveyor belt 203. The discharge end of the discharge plate 105 faces the discharge port 103. The magnetic separator 1 has a receiving box 801 and a slag storage box 802 installed at the slag discharge port 102 and the discharge port 103, respectively. The connecting rod 702 has a triangular wall 703 to prevent impurities from accumulating on the connecting rod 702.

[0022] Start the feeder next to the raw material pile to evenly transport the zirconium titanium ore raw material to the feeding conveyor belt 201, control the raw material feeding amount, and avoid raw material accumulation.

[0023] The feeding conveyor belt 201 transports the raw material to the feeding hopper 101. The raw material falls from the bottom of the feeding hopper 101 to the baffle plate 104. Under the guidance of the baffle plate 104, it is evenly distributed in the middle of the primary conveyor belt 202. The primary conveyor belt 202 transports the raw material to the unloading end. Under the action of gravity, the raw material falls to the outer wall of the conical barrel 3 of the magnetic separator above.

[0024] The conical barrel 3 of the upper magnetic separator rotates at a constant speed. During the fall of the raw material, it comes into full contact with the outer wall 4 of the energized electromagnet. The strongly magnetic impurities in the raw material are adsorbed onto the surface of the outer wall 4 of the electromagnet under the action of the magnetic field, while the non-magnetic zirconium-titanium ore particles continue to fall. The adsorbed strongly magnetic impurities move to the side where the scraper 5 is located as the conical barrel 3 rotates. When the impurities rotate to the point where the scraper 5 and the outer wall 4 of the electromagnet are in contact, the scraper 5 generates a scraping force on the impurities. At the same time, the outer wall 4 of the electromagnet at that position is temporarily de-energized, and the impurities fall off and fall into the slag discharge conveyor belt 204 below. The unadsorbed zirconium-titanium ore particles continue to fall and land on the secondary conveyor belt 203, completing the primary magnetic separation.

[0025] The secondary conveyor belt 203 transports the zirconium-titanium ore after the initial magnetic separation to the feeding end. Under the action of gravity, the raw material falls onto the outer wall of the conical barrel 3 of the lower magnetic separator. The conical barrel 3 of the lower magnetic separator rotates at a uniform speed, and the magnetic field strength of the outer wall 4 of the electromagnet is higher. The weak magnetic impurities in the raw material are adsorbed onto the surface of the outer wall 4 of the electromagnet under the action of the strong magnetic field. As the conical barrel 3 rotates to the scraper 5, the corresponding outer wall 4 of the electromagnet is temporarily de-energized. After the impurities are scraped off, they fall into the slag discharge conveyor belt 204. After two magnetic separations, the zirconium-titanium ore particles that meet the purity standards continue to fall. Guided by the discharge plate 105, they fall from the discharge port 103 into the receiving box 801, completing the collection of concentrate.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
