Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic separator equipment, in particular to a spring magnetic medium for a vertical ring high gradient magnetic separator. Background Art

[0002] Magnetic separator is a common solid particle separation equipment, widely used in mining, metallurgy, chemical industry and other fields. Its working principle is to screen particles through magnetic field and separate particles with certain magnetism from the mixture. The medium box of magnetic separator is one of the key components, which is responsible for containing magnetic particles and effectively separating them.

[0003] However, the medium box of the magnetic separator may face some problems during long-term operation, one of which is clogging. The clogging of the medium box is mainly due to the mutual adsorption of particles under the action of the magnetic field, which causes them to gradually accumulate in the medium box to form a blockage. This phenomenon is especially significant when dealing with fine particles or particles with strong adhesion. The blockage not only affects the separation efficiency of the magnetic separator, but also increases the difficulty of equipment maintenance. The clogging problem of the medium box is not easy to solve because its internal structure is relatively complex and difficult to clean directly. Utility Model Content

[0004] The utility model aims to provide a spring magnetic medium for a vertical ring high gradient magnetic separator to solve the problems raised in the above-mentioned prior art.

[0005] Provided is a vertical ring high gradient magnetic separator spring magnetic medium, comprising:

[0006] A medium box body;

[0007] The spring magnetic medium comprises a plurality of closely arranged magnetic conductive springs, and the spring magnetic medium is arranged inside a medium box body.

[0008] Furthermore, the medium box body is provided with a plurality of baffles and is divided into a plurality of mutually independent spaces by the baffles.

[0009] Furthermore, the baffle and the medium box body are detachably connected.

[0010] Furthermore, the magnetic spring is made of 00Cr12 stainless steel or Q195 chromium-plated stainless steel.

[0011] Furthermore, the magnetic conductive springs in two adjacent rows are arranged alternately.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Arrange the magnetic conductor in the form of a spring inside the medium box to form a grid-shaped screening medium. Since the magnetic spring can form a stable support structure after being combined, the spring magnetic medium does not need to be fixedly connected to the medium box, so that the spring magnetic medium can be taken out independently. Therefore, when the medium is blocked, the spring magnetic medium can be taken out of the medium box for cleaning to ensure the cleaning effect.

[0014] 2. The circular hole in the middle of the magnetic spring has a large space for the slurry to flow through, and the magnetic material is captured and arranged by the magnetic spring under the action of the magnetic field, and the screening efficiency is high. The circular hole of the spring is not easy to be blocked, and even if the circular hole is blocked, it can be dredged by a slender rod or a high-pressure water gun, without taking out the entire spring magnetic medium, and the dredging method is flexible.

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2As shown, in the embodiment of the utility model, a vertical ring high gradient magnetic separator spring magnetic medium comprises a medium box 1 and a spring magnetic medium 2. The spring magnetic medium 2 comprises a plurality of closely arranged magnetic conductive springs 21, and the spring magnetic medium 2 is arranged inside the medium box 1.

[0023] The spring magnetic medium 2 is a magnetic medium that helps to enhance the effect of the magnetic field and guide and capture particles during the separation process. A number of magnetic springs 21 are closely arranged to form a three-dimensional grid-like spring magnetic medium 2. The magnetic spring 21 has a circular hole in the middle and a spiral gap around it for the pulp and magnetic fluid to pass through and be screened. The pulp flows from top to bottom into the medium box 1 and passes through these spring magnetic media 2. Under the action of the magnetic field, particles with a certain degree of magnetism are attracted by the magnetic force, move along the direction of the magnetic field, and are captured or arranged by the magnetic springs 21 in the medium box 1. This allows the magnetic particles to be effectively separated from the mixture. Non-magnetic particles are subject to a smaller magnetic force and usually pass through the medium box 1 along the direction of the magnetic field without being captured. In this way, the magnetic separator achieves effective separation of magnetic and non-magnetic particles in the mixture.

[0024] A number of magnetic springs 21 are closely arranged to form a spring magnetic medium 2, which is fully distributed inside the medium box body 1. The inner wall of the medium box body 1 provides lateral support, so that the spring magnetic medium 2 is stably arranged and the overall structure will not be damaged even if it is impacted by slurry.

[0025] A plurality of baffles 11 are arranged inside the medium box 1 and are divided into a plurality of independent spaces by the baffles 11. The medium box 1 is divided into a plurality of independent compartments by the baffles 11, which can reduce the volume of a single spring magnetic medium 2, facilitate the installation of the spring magnetic medium 2, enhance the strength and rigidity of the medium box 1, and improve the stability of the spring magnetic medium 2.

[0026] Furthermore, the baffle 11 is detachably connected to the medium box body 1. When the spring magnetic medium 2 needs to be installed or removed, the baffle 11 can be removed by sliding and pulling out, thereby providing space for the spring magnetic medium 2 to enter and exit. In particular, if there is an obstruction of the baffle 11, the magnetic springs 21 in this row close to the baffle 11 are difficult to overcome the interference of the magnetic springs 21 in the adjacent row. After the baffle 11 is removed, the installation and removal work can be completed smoothly. At the same time, the detachable baffle 11 still has the function of increasing the strength of the medium box body 1.

[0027] The material used for the magnetic spring 21 is 00Cr12 stainless steel or Q195 chromizing. Q195 chromizing is to form a chromium compound layer on the surface of Q195 low carbon steel through a surface treatment process to improve the wear resistance and corrosion resistance of the material and reduce the wear and corrosion effects of the slurry on the magnetic spring 21. 00Cr12 stainless steel or Q195 chromizing has strong plasticity and can be molded into a spring shape. It has high strength and is not easy to deform. It does not need to have the strong deformation and high resilience of ordinary springs. It can effectively resist the impact, wear and corrosion caused by the slurry. In addition, it has high magnetic conductivity and can effectively cooperate with the magnetic field to complete the slurry screening work.

[0028] See also Figure 1 and Figure 3 As shown, two adjacent rows of magnetic conductive springs 21 are arranged alternately. This arrangement improves the overall stability of the spring magnetic medium 2 and reduces the difficulty of installation.

[0029] The above contents are merely examples and explanations of the structure of the utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
