Description

Technical Field

[0001] This utility model relates to the field of omphacite recovery devices, specifically to an integrated omphacite gradient flotation-magnetic separation recovery device. Background Technology

[0002] Omnimorphite is a magnesium- and iron-containing silicate mineral, commonly used for extracting magnesium and manufacturing refractory materials. When processing ores containing omnimorphite, flotation and magnetic separation are two commonly used separation techniques. Omnimorphite flotation involves adding specific chemical reagents to cause omnimorphite to adhere to air bubbles, which then rise to the surface of the slurry, forming a foam layer. Magnetic separation is a physical method that separates minerals based on differences in magnetic properties. Since omnimorphite itself is non-magnetic, under the influence of a magnetic field, magnetic impurities (such as magnetite) mixed within it are removed, thus achieving separation.

[0003] However, in current equipment for processing omphacite, flotation and magnetic separation are carried out separately. This requires two independent devices or processes, which increases the need for material transfer, storage, and processing. Each process requires separate operation and monitoring, increasing the need for manual intervention and leading to reduced efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0012] Furthermore, in order to separate the omphacite adhering to the foam, the output end of the motor is connected to one end of the rotating rod, and the passive pulley is connected to one end of the flotation rake through a bushing.

[0013] Furthermore, in order to fully mix the chemical reagents and omphacite slurry, the flotation mechanism includes an L-shaped plate symmetrically arranged at one end of the flotation box. The L-shaped plate is connected to a second motor by bolts and nuts. The output end of the second motor is connected to a second drive pulley by a bushing. A second driven pulley is provided on one side of the second drive pulley. The second drive pulley and the second driven pulley are connected by a second belt.

[0014] Furthermore, in order to make the foam produced by the omphacite slurry richer, the passive pulley two is connected to one end of the stirring rod through a bushing, and the other end of the stirring rod is equipped with stirring blades. The stirring rod is connected to a protective groove through a bearing, and a circular plate is connected to the end of the protective groove near the stirring blades. The protective groove is connected to a ventilation pipe.

[0015] Furthermore, a fixing plate is connected to the side of the protective tank away from the stirring blades. The fixing plate is connected to the support base by bolts and nuts, and the support base is welded above the flotation tank.

[0016] Furthermore, to make the drive unit more stable, the L-shaped plate is connected to a diagonal brace near the fixed plate by bolts and nuts, and the bottom of the diagonal brace is connected to the support base.

[0017] The beneficial effects of this utility model are as follows: by setting up a magnetic separation mechanism in the flotation box, the process flow is shortened, intermediate steps (such as dewatering, regrinding, etc.) are reduced, and time and energy consumption are reduced; the collection tank and collection box work together to directly recover magnetic minerals in the flotation omphacite tailings through magnetic separation, avoiding waste of valuable components; direct magnetic separation after flotation can reduce tailings discharge, improve the overall recovery rate, and the integrated system makes it easier to achieve water circulation, reducing fresh water consumption and wastewater treatment pressure.

The flotation box 2 is provided on one side of the collection box 1, and the supports 3 are symmetrically provided on both sides of the flotation box 2. The supports 3 are connected to the flotation rake 4 through bearings. The flotation rake 4 is driven by a motor to scrape the foam rich in target minerals on the surface of the flotation box 2 into the collection box 1. A magnetic separation mechanism 6 is provided on one side of the flotation rake 4. The magnetic separation mechanism 6 includes a collection box 601. A scraper 605 is connected to one end of a collection trough 602, and a support leg 603 is connected to the other end of the collection trough 602. An inclined scraper 605 is provided above the collection trough 602. The scraper 605 is connected to the rotating rods 604 at both ends of the magnetic roller 606 via a scraper frame 607. Magnetic blocks are provided on the inner wall of the bottom of the magnetic roller 606. The magnetic roller 606 is rotatably connected to the rotating rods 604, and a bracket 608 is provided at the end of the rotating rods 604. The rotating rods 604 drive the magnetic roller 606 to rotate to the area of ​​the scraper 605, and the scraper 605 scrapes the metal material adsorbed on the surface of the magnetic roller 606 into the collection trough 602. In the process, the collection tank 602 adopts an inclined design, making it easier for the collected metal materials to flow into the collection box 601. The collection tank 602 and the collection box 601 work together to directly recover the magnetic minerals in the flotation tailings of omphacite through magnetic separation, avoiding the waste of valuable components. A flotation mechanism 9 is provided on one side of the magnetic separation mechanism 6, and a drive mechanism 5 is provided on the other end of the rotating rod 604. The drive mechanism 5 includes a motor frame 501, and a motor 502 is fixedly connected to the top of the motor frame 501. The motor 502 is connected to a drive pulley 503 through a bushing. A passive pulley 505 is provided on one side of 503. The active pulley 503 and the passive pulley 505 are connected by a belt 504 to provide power to the magnetic separation mechanism 6 and the flotation rake 4. The output end of the motor 502 is connected to one end of the rotating rod 604. The passive pulley 505 is connected to one end of the flotation rake 4 through a bushing. The flotation rake 4 can separate the omphacite attached to the foam. By setting the magnetic separation mechanism 6 in the flotation box 2, the process flow is shortened, intermediate steps (such as dewatering, regrinding, etc.) are reduced, and time and energy consumption are reduced.

[0030] Example 2;

[0031] like Figure 1 , Figure 4 and Figure 5As shown, the integrated gradient flotation-magnetic separation recovery device for omphacite according to an embodiment of this utility model includes a flotation mechanism 9. The flotation mechanism 9 includes an L-shaped plate 901 symmetrically arranged at one end of a flotation tank 2. The L-shaped plate 901 is connected to a motor 902 via bolts and nuts. The output end of the motor 902 is connected to a drive pulley 903 via a bushing. A driven pulley 905 is provided on one side of the drive pulley 903. The drive pulley 903 and the driven pulley 905 are connected by a belt 904. The driven pulley 905 is connected to one end of a stirring rod 906 via a bushing. The other end of the stirring rod 906 is provided with stirring blades 909. The stirring rod 906 is connected to a stirring blade 909 via a bushing. The bearing is connected to a protective groove 907, which prevents the stirring rod 906 from being damaged by friction from the ore during operation. A circular plate 908 is connected to the end of the protective groove 907 near the stirring blade 909. The circular plate 908 reduces the interference of ore falling from above the flotation cell with the blade operation. A fixing plate 8 is connected to the side of the protective groove 907 away from the stirring blade 909. The fixing plate 8 is connected to the support base 10 by bolts and nuts. The support base 10 is welded to the top of the flotation box 2. An L-shaped plate 901 is connected to a diagonal brace 910 near the fixing plate 8 by bolts and nuts. The bottom of the diagonal brace 910 is connected to the support base 10. The diagonal brace 910 makes the drive device more stable.

[0032] In summary, using the above-mentioned technical solution of this utility model, during use, the operator puts the pre-ground omphacite slurry and chemical reagents into the flotation tank 2, starts motor 502 and motor 902, motor 902 drives the active pulley 903 to rotate, which in turn drives the passive pulley 905 to rotate the stirring rod 906. The rotation of the stirring rod 906 mixes the reagents and omphacite slurry evenly and gradually produces foam. The ventilation pipe 7 allows external oxygen to enter the slurry. As more and more foam containing omphacite ore accumulates above the flotation tank 2, due to the inclined structure of the surface of the flotation tank 2, the foam continuously flows towards the inclined area. When it flows to the magnetic separation mechanism 6, the magnetic roller 60... The magnetic blocks inside the magnetic roller 606 adsorb the metal material in the passing foam onto the outer surface of the magnetic roller 606. As the magnetic roller 606 rotates, the scraper 605 between the scraper frames 607 on both sides removes the metal material adsorbed on the surface of the magnetic roller 606 and hangs it into the collection tank 602 below. The inclined design of the collection tank 602 allows the metal material in the tank to flow into the collection box 601. The ore foam after magnetic separation continues to flow in the inclined direction. The flotation rake 4 is driven by a motor to scrape the foam rich in omphacite minerals on the surface of the flotation box 2 into the collection box 1. Direct magnetic separation after flotation can reduce tailings discharge, improve the overall recovery rate, and the integrated system makes it easier to realize water circulation, reduce fresh water consumption and wastewater treatment pressure.
