Description

Technical Field

[0001] The utility model relates to the field of material processing, and particularly relates to an iron removing device for a dry powder material production line. Background Technique

[0002] With the development of high-tech and new energy new materials industries, these industries are often closely related to mineral raw materials or mineral materials; for mineral raw materials or mineral materials, ferromagnetic impurities such as iron and titanium contained in non-metallic materials will seriously affect the product quality, and thus affect the industrial utilization of non-metallic materials. Iron in quartz will not only affect the whiteness, but also seriously affect the dielectric conductivity and chemical stability of products. Since some minerals and materials will change their properties and lose their value when exposed to water, water cannot be present during the purification and processing, and impurity removal needs to be achieved through dry beneficiation; in order to effectively remove ferromagnetic impurities in non-metallic powdery materials and minimize the adverse effects of ferromagnetic impurities on products, electromagnetic dry powder iron removers are widely used in the market to achieve the above goals. And there are many iron removing devices used in the mining system in the prior art. Therefore, it is an urgent problem to be solved at present to develop an iron remover for a dry powder material production line that can be applied to a production line and can effectively remove silicon iron impurities in dry powder materials.

[0017] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following further illustrates the technical solutions of the iron removal device for the dry powder material production line of the present invention in combination with the drawings of the specification and through specific embodiments.

[0018] As Figure 1As shown in the figure, the utility model provides an iron removal device for a dry powder material production line. The device mainly includes a material flow channel 1 and an iron removal chamber 2. An inlet 3 and an outlet 4 are provided on the material flow channel 1. The middle part of one side of the material flow channel 1 is open and communicated with the iron removal chamber 2. A roller 5 is arranged at the opening where the iron removal chamber 2 is communicated with the material flow channel 1. A strong magnet 7 fixed inside the roller is arranged on the inner wheel of the roller 5. A roller drive shaft 6 is installed on the central axis inside the roller 5. A drive motor 8 is arranged at the top of the iron removal chamber 8. The motor drive shaft 9 on the drive motor 8 is connected to the roller drive shaft 6 through a transmission belt 11. An iron outlet 10 is provided at the lower opening of the iron removal chamber 2.

[0019] The above-mentioned strong magnet 7 fixed inside the roller is a tile-shaped magnet, and the magnet is radially magnetized.

[0020] The material of the above-mentioned material flow channel 1 is a polymer slide plate.

[0021] The above-mentioned roller 5 wheel is in a hollow shape.

[0022] An exhaust air duct machine is provided outside the above-mentioned iron removal device, and the inside of the device is in a negative pressure during operation.

[0023] When the device is specifically used, the drive motor 8 drives the roller drive shaft of the iron removal device through a belt. The strong magnet 7 fixed inside the roller installed on the upper half of the inner edge of the inner wheel makes the upper part of the inner wheel always have magnetism. During the process of the inner wheel rotating driven by the motor drive shaft, the ferrosilicon impurities in the dry powder material are adsorbed to the outside of the inner wheel. When the inner wheel rotates to the lower horizontal position, the adsorbed ferrosilicon impurities fall off magnetically and drop to the iron outlet 10. In order to prevent the material from being affected by the inclination of the feeding pipe, so that the material directly falls onto the outlet pipe after being turned over by the inner wheel, an exhaust air duct machine is provided outside the iron removal device in the present invention to ensure that the inside of the device is in a negative pressure during the whole operation, and the powder will not fall into the iron outlet along with the ferrosilicon. The best angle for installing the pipeline of the iron removal device is 45°. If the angle is too large, the feeding amount will be too fast and the iron removal will be incomplete. If the angle is too small, the material will accumulate and cause the device to be blocked.

[0024] Next, the technical solutions and technical effects of the present utility model will be further described in conjunction with specific embodiments.

[0025] Embodiment 1

[0026] As Figure 2The iron removal device shown is a square device. The bottom of the material flow channel inside the device is flush with the feed pipe. The drum is horizontally arranged in the iron removal chamber of the device. Affected by the downward inclination angle of the pipeline, the material automatically falls to the drum. Magnets are arranged on the upper half of the inner side of the drum. The falling material is turned over by the drum, and the ferrosilicon impurities in the material are adsorbed on the cylinder body. The material continues to fall into the discharge pipe. The ferrosilicon impurities adsorbed by the drum continue to be turned over along the drum until they become non-magnetic below and then directly fall into the iron outlet.

[0027] In summary, the utility model is applicable to the dry powder material production line. By providing negative pressure through a high-pressure air compressor, it can effectively avoid dusting; and better remove ferrosilicon impurities in the dry powder material.

[0028] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all embodiments, and are not intended to limit the utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention shall be included within the protection scope of the present utility model.
