Description

Technical Field

[0001] This utility model relates to the field of vanadium-titanium magnetite beneficiation technology, and in particular to a magnetic separation device for efficient beneficiation of vanadium-titanium magnetite. Background Technology

[0002] Vanadium-titanium magnetite is an important mineral resource, whose main components include elements such as iron, vanadium, and titanium. Magnetic separation is a commonly used method in the beneficiation of vanadium-titanium magnetite, which separates the valuable minerals from the gangue minerals by utilizing the differences in the magnetic properties of the minerals.

[0003] The existing feeding structure of magnetic separation equipment for vanadium-titanium magnetite is usually an inclined guide plate. This simple design makes it difficult to accurately adjust the feeding amount according to the actual screening conditions. When too much material is fed, the magnetic separation drum cannot fully separate a large amount of ore per unit time, resulting in some magnetic minerals not being effectively adsorbed, reducing the recovery rate of concentrate. At the same time, too much ore may also cause equipment blockage, affecting the normal operation of the magnetic separation equipment. On the other hand, when too little material is fed, the processing capacity of the screening equipment is not fully utilized, which will reduce production efficiency and increase production costs.

[0004] Therefore, a magnetic separation device for efficient separation of vanadium-titanium magnetite is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A magnetic separation device for efficient separation of vanadium-titanium magnetite includes a drum magnetic separator body 1, a feeding mechanism 2 is provided on the top of the drum magnetic separator body 1, and a washing assembly 3 is provided on the front side of the drum magnetic separator body 1.

[0029] The feeding mechanism 2 includes a storage bin 201. The inner cavity of the storage bin 201 is equipped with a stirring assembly 202. A feeding outlet 203 is opened at the bottom of the front side of the storage bin 201. The feeding outlet 203 is located at the top of the magnetic separation drum of the drum magnetic separator body 1. A fixing plate 204 is fixedly connected to the front side of the storage bin 201. An electric telescopic rod 205 is fixedly connected to the top of the fixing plate 204. The output rod of the electric telescopic rod 205 passes through the fixing plate 204 and is fixedly connected to an adjusting baffle 206 that works in conjunction with the feeding outlet 203.

[0030] In this embodiment: by setting up a drum magnetic separator body 1, a feeding mechanism 2, and a washing component 3, during use, the drum magnetic separator body 1 can be used to sort vanadium-titanium magnetite. The feeding mechanism 2 can store the vanadium-titanium magnetite slurry to be sorted and can continuously feed the vanadium-titanium magnetite slurry to the magnetic separation drum of the drum magnetic separator body 1. The feeding amount can be precisely adjusted according to the actual screening conditions to avoid overfeeding or underfeeding, ensuring that the magnetic separation device is always in the best working state, effectively improving the sorting effect and production efficiency. The washing component 3 can wash off the concentrate adsorbed on the surface of the drum of the drum magnetic separator body 1, reducing concentrate residue, improving concentrate collection rate, and avoiding resource waste.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the rinsing assembly 3 includes a rinsing pipe 301, an external water pipe 302 connected to the right side of the rinsing pipe 301, and a rinsing nozzle 303 connected to the rear side of the rinsing pipe 301. The rinsing pipe 301 and the rinsing nozzle 303 are located in front of the magnetic separation drum of the drum magnetic separator body 1.

[0032] Specifically, such as Figure 1 , Figure 5 As shown, fixing blocks 304 are fixedly connected to both sides of the bottom of the rinsing pipe 301, and the bottom of the fixing blocks 304 is fixedly connected to the frame of the drum magnetic separator body 1.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, there are several flushing nozzles 303, which are evenly distributed on the rear side of the flushing pipe 301.

[0034] In this embodiment: by setting up a flushing pipe 301, an external water pipe 302, a flushing nozzle 303, and a fixing block 304, in use, by connecting the external water pipe 302 to a water source, water enters the flushing pipe 301 from the external water pipe 302 and is then sprayed out through the flushing nozzle 303, which can wash off the concentrate adsorbed on the surface of the drum of the drum magnetic separator body 1, reduce the residue of concentrate, improve the collection rate of concentrate, and avoid waste of resources. The fixing block 304 can support and fix the flushing pipe 301.

[0035] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the stirring assembly 202 includes a stirring motor 202a, which is fixedly connected to the right side of the storage silo 201. The output shaft of the stirring motor 202a is fixedly connected to a stirring shaft 202b. The left side of the stirring shaft 202b extends through to the left side of the storage silo 201. Both sides of the surface of the stirring shaft 202b are rotatably connected to the inner wall of the storage silo 201 through sealed bearings.

[0036] Specifically, such as Figure 2 , Figure 3 , Figure 4 As shown, stirring blades 202c are fixedly connected to the surface of stirring shaft 202b. There are several stirring blades 202c, which are evenly distributed on the surface of stirring shaft 202b.

[0037] In this embodiment: by setting up a stirring motor 202a, a stirring shaft 202b, and stirring blades 202c, when in use, by starting the stirring motor 202a, the output shaft of the stirring motor 202a drives the stirring shaft 202b to rotate, and the stirring shaft 202b drives the stirring blades 202c to rotate. The rotation of the stirring blades 202c can stir the vanadium-titanium magnetite slurry in the storage bin 201, prevent the vanadium-titanium magnetite slurry from settling or stratifying, ensure the uniformity of the slurry concentration, and provide stable quality ore for the subsequent magnetic separation process.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, support frames 4 are fixedly connected to the bottom of both sides of the storage bin 201, and the bottom of the support frames 4 is fixedly connected to the frame of the drum magnetic separator body 1.

[0039] Specifically, such as Figure 3 As shown, the top of the fixed plate 204 is provided with a through hole 5 for use with the electric telescopic rod 205, and the output rod of the electric telescopic rod 205 is slidably connected to the inner wall of the through hole 5.

[0040] In this embodiment: the storage bin 201 can be supported and fixed by setting the support frame 4, and the output rod of the electric telescopic rod 205 can be extended and retracted by setting the through hole 5.

[0041] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, both sides of the top of the adjusting baffle 206 are fixedly connected to limit guide rods 6, and the top of the limit guide rods 6 extends through to the top of the fixed plate 204.

[0042] Specifically, such as Figure 3 As shown, sliding holes 7 are provided on both sides of the top of the fixed plate 204 to cooperate with the limiting guide rod 6, and the surface of the limiting guide rod 6 is slidably connected to the inner wall of the sliding hole 7.

[0043] In this embodiment: by setting the limiting guide rod 6, the adjusting baffle 206 can be guided and limited, so that the adjusting baffle 206 can move up and down stably. By setting the sliding hole 7, the limiting guide rod 6 can pass through the fixed plate 204 to move up and down.

[0044] Working principle: During the separation of vanadium-titanium magnetite, the vanadium-titanium magnetite slurry to be separated is poured into the storage silo 201. Then, the stirring motor 202a is started, causing the output shaft of the stirring motor 202a to drive the stirring shaft 202b to rotate. The stirring shaft 202b drives the stirring blades 202c to rotate. The rotation of the stirring blades 202c can stir the vanadium-titanium magnetite slurry in the storage silo 201, preventing sedimentation and stratification of the vanadium-titanium magnetite slurry, ensuring uniform slurry concentration, and providing stable quality ore for the subsequent magnetic separation process. Then, the vanadium-titanium magnetite slurry flows through the feed outlet 203 to the magnetic separation drum of the drum magnetic separator body 1 for feeding. When the feed rate needs to be adjusted according to the actual magnetic separation and screening conditions, the electric telescopic rod 205 can be activated, causing the output rod of the electric telescopic rod 205 to move the adjusting baffle 206 up and down. When the feed rate needs to be increased, the output rod of the electric telescopic rod 205 retracts, the adjusting baffle 206 moves upward, and the feed outlet 203 increases. When the feed rate needs to be decreased, the output rod of the electric telescopic rod 205 extends, adjusting the feed outlet 203. The baffle 206 moves downward, reducing the feed outlet 203. This precisely controls the amount of ore flowing out of the feed outlet 203, ensuring that an appropriate amount of ore falls evenly onto the top of the magnetic separator drum of the drum magnetic separator body 1. Then, the magnetic separator drum of the drum magnetic separator body 1 begins to rotate under the drive of the drive device. Its internal magnetic system generates a magnetic field of specific intensity and distribution. When the vanadium-titanium magnetite slurry falls onto the magnetic separator drum, the magnetic minerals are adsorbed onto the surface of the magnetic separator drum under the action of the magnetic field force and are carried away as the magnetic separator drum rotates. Minerals that are not magnetic or have very weak magnetic properties are not affected by the magnetic field and slide directly off the magnetic separator drum, becoming tailings. When the magnetic separator drum containing magnetic minerals rotates to the position of the washing component 3, water is connected to the water source through the external water pipe 302, and then water enters the washing pipe 301 through the external water pipe 302 and is sprayed out through the washing nozzle 303. This washes off the concentrate adsorbed on the surface of the drum of the magnetic separator body 1, reducing concentrate residue, improving concentrate collection rate, and avoiding waste of resources.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
