Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separators, in particular to a large-scale and efficient magnetic separator unloading gravity water curtain. Background Art

[0002] A magnetic separator is a separation device used to remove iron and other fines from recycled powdered particles. After the slurry flows through the feed box and into the trough, the water flow from the feed water pipes loosens the ore particles and enters the feed area of ​​the trough. Under the influence of the magnetic field, the magnetic particles gather and form "magnetic clusters" or "magnetic chains." These "magnetic clusters" or "magnetic chains" are attracted to the magnetic poles in the slurry and attracted to the drum. Because the polarity of the magnetic poles alternates along the drum's rotation and remains stationary during operation, the "magnetic clusters" or "magnetic chains" generate magnetic agitation as the drum rotates. Non-magnetic minerals such as gangue are dislodged from these "magnetic clusters" and fall into the tailings trough. The "magnetic clusters" or "magnetic chains" that are finally attracted to the drum's surface are the concentrate. They follow the drum to the edge of the magnetic system, where the magnetic force is weakest, and are discharged into the concentrate trough by the water curtain, completing the separation.

[0003] The traditional method of unloading magnetic separators is to use a rubber scraper to scrape the surface of the drum. When scraping off the magnetite powder, the scraper causes the magnetite powder to rub against the magnetic separator drum, which will cause deep or shallow grooves to be worn on the drum surface. When the grooves reach a certain depth, the wear-resistant leather on the surface of the magnetic separator drum needs to be replaced. Because the steps for replacing the wear-resistant leather are cumbersome and difficult, it affects normal production and costs a lot of money. In addition, some unloading water curtains are not clean, which will cause ore to accumulate and cannot work properly. Therefore, there is an urgent need for a large-scale and efficient magnetic separator unloading gravity water curtain to solve this problem. Utility Model Content

[0006] Preferably, a drainage plate is fixedly installed at an angle at the water outlet of the water receiving trough, which gradually approaches the working surface of the magnetic separator drum from the upper end to the lower end. The length of the drainage plate is not less than the length of the working surface of the magnetic separator drum, and the vertical planes where the two ends of the working surface of the magnetic separator drum are located are both located between the two ends of the drainage plate.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1:

[0020] See Figure 1 and 2 A large-scale and efficient magnetic separator unloading gravity water curtain includes an unloading water pipe 3 connected to the water outlet end of a valve 1, and also includes a water receiving trough 5, which is located above the plane where the center line of the magnetic separator drum 7 is located, and the water receiving trough 5 is fixedly connected to the magnetic separator body 2; a water outlet trough is opened on the upper part of the water receiving trough 5 close to the magnetic separator drum 7, and the length of the water outlet trough is not less than the length of the working surface of the magnetic separator drum 7, and the vertical planes where the two ends of the working surface of the magnetic separator drum 7 are located are both located between the two ends of the water outlet trough; an adsorption layer 51 is laid at the lower end of the water receiving trough 5 for adsorbing some impurities in the unloading water; the outlet of the unloading water pipe 3 is connected to the water receiving trough 5.

[0021] like Figure 2 As shown, in this embodiment, since the distance between the inner wall of the magnetic separator body 2 and the magnetic separator drum 7 is not suitable for direct water discharge from the water receiving trough 5, a drainage plate 6 is fixedly provided at an angle at the water outlet of the water receiving trough 5. For reference, the angle between it and the vertical direction can be 45°, and it gradually approaches the working surface of the magnetic separator drum 7 from the upper end to the lower end. The length of the drainage plate 6 is not less than the length of the working surface of the magnetic separator drum 7, and the vertical planes where the two ends of the working surface of the magnetic separator drum 7 are located are both located between the two ends of the drainage plate 6.

[0022] In order to prevent the unloading water pipe 3 from rotating due to the impact of water flow when the water flows through, a plurality of fixed plates 4 are welded to the lower end of the unloading water pipe 3. The fixed plates 4 are fixedly connected to the magnetic separator body 2 and / or the water receiving trough 5. The specific form of the fixed plates 4 can be welded only to the lower end of the unloading water pipe 3 as shown in the figure, or can be welded and sleeved on the outer periphery of the unloading water pipe 3, etc., so as to achieve the effect of limiting the rotation of the unloading water pipe 3.

[0023] Example 2:

[0024] On the basis of the above-mentioned embodiment 1, since the unloading water pipe 3 adopts circulating water, impurities occasionally remain in it after flocculation and other treatment processes. If a filter screen or other methods are used to intercept it, it may cause the water channel resistance to become larger. However, after adopting the above embodiment, the water receiving trough 5 can also play the role of settling impurities, which can make the water for washing the concentrate cleaner. However, under the action of water flow, impurities may still flow out from the water outlet. Therefore, in the above scheme, an adsorption layer 51 is laid at the lower end of the water receiving trough 5. In order to further increase the effect of this structure, in this embodiment, the upper end face of the adsorption layer 51 is set to an uneven curved surface, which not only increases the adsorption area, but also makes it easier to retain impurities at the lower end of the water receiving trough 5, and can be cleaned and replaced during inspection and maintenance. The adsorption layer 51 is preferably made of sponge or activated carbon.

[0025] Example 3:

[0026] like Figure 3 As shown, on the basis of the above-mentioned embodiment 2, in order to facilitate the cleaning and replacement of the adsorption layer 51, the water receiving trough 5 is detachably fixedly connected to the magnetic separator body 2 in this embodiment. Specifically, a mounting plate is welded and fixed on one side of the magnetic separator drum 7 inside the magnetic separator body 2, and a plurality of fixed plates 4 are welded to the lower end of the unloading water pipe 3. The fixed plate 4 is welded and fixed to the upper part of the mounting plate. A hanging groove is provided on the side of the lower part of the mounting plate close to the unloading water pipe 3, and a hook matching the hanging groove is welded on the outer wall opposite to the water outlet of the water receiving trough 5. The water receiving trough 5 is detachably hung on one side of the lower part of the mounting plate.

[0027] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined by the claims.
