Description

Technical Field

[0001] The utility model relates to the field of electromagnetic iron removers, in particular to an electromagnetic iron remover for high-viscosity slurry. Background Art

[0002] An electromagnetic iron remover is a device that uses the principle of electromagnetic force to remove ferromagnetic materials from materials. It is usually composed of an electromagnetic coil and magnetic material. By passing electricity through it, it generates a magnetic field that attracts and collects ferromagnetic impurities, thereby removing iron from the material.

[0003] In the prior art, electromagnetic iron removers often adsorb magnetic substances in the slurry through the magnetic field generated by their own power supply, thereby ensuring the purity of the raw materials.

[0004] However, in actual use, when the magnetic material inside the slurry is adsorbed into the electromagnetic iron remover, a filtering device needs to be used to filter the slurry simultaneously. As a result, some impurities will adhere to one side of the filter due to the movement of the fluid, causing the filter to be blocked to a certain extent, thereby affecting its subsequent work efficiency. Therefore, a high-viscosity slurry electromagnetic iron remover is proposed to solve the above problem. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a high-viscosity slurry electromagnetic iron remover, which aims to improve the problem in the prior art that impurities in the slurry adhere to the inside of the electromagnetic iron remover and easily cause blockage at its discharge port.

[0010] As a further description of the above technical solution:

[0011] The upper end of the base is provided with a supporting leg, and the upper end and the right end of the electromagnetic iron remover are both provided with through holes.

[0012] As a further description of the above technical solution:

[0013] A through hole is provided at the center of the inner surface of the impeller, and a plurality of groups of arc-shaped inclined blades are provided on the outer arc surface of the impeller.

[0023] 1. In the utility model, through the provision of support rods, impellers, rotating shafts, bearings, and brush rods, when the slurry enters the electromagnetic iron remover from the feed port, the high viscosity characteristic makes it easy for the slurry to carry impurities during the flow process. At this time, the impeller will generate a certain rotational force when the slurry passes through. This rotational force acts on the rotating shaft, thereby driving the brush rod to rotate. The multiple groups of bristles densely arranged at the end of the brush rod away from the rotating shaft can fit closely to the inner wall of the electromagnetic iron remover or the surface of the filter screen, effectively removing impurities and ferromagnetic substances attached thereto.

[0031] 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.

[0032] Reference Figure 1-Figure 2 The utility model provides an embodiment: an electromagnetic iron remover for high-viscosity slurry, comprising a base 1, an electromagnetic iron remover 4 is fixedly connected to the upper surface of the base 1, a feed port 5 is fixedly connected to the upper end of the electromagnetic iron remover 4, an automatic shielding device 3 is provided inside the feed port 5, and an automatic cleaning device 2 is provided at the discharge port of the electromagnetic iron remover 4;

[0033] The automatic cleaning device 2 includes a rotating shaft 203, an impeller 202 is fixedly connected to the outer arc surface of the rotating shaft 203, a bearing 204 is fixedly connected to the middle of the rotating shaft 203, a support rod 201 is fixedly connected to the outer arc surface of the bearing 204, and a brush rod 205 is fixedly connected to the end of the rotating shaft 203 away from the impeller 202.

[0034] A support leg is provided at the upper end of the base 1, so that it can provide support for the electromagnetic iron remover 4 above. The upper end and the right end of the electromagnetic iron remover 4 are both provided with through holes, which are the feed port 5 and the discharge port thereof respectively. A through hole is provided at the center of the inner surface of the impeller 202, so that it can be fixedly connected to the rotating shaft 203. A plurality of groups of arc-shaped inclined blades are provided at the outer arc surface of the impeller 202, so that it can be driven to rotate during the flow of the slurry. The inner arc surface and the outer arc surface of the bearing 204 are respectively fixedly connected to the rotating shaft 203 and the support rod 201. There are multiple groups of support rods 201, and the multiple groups of support rods 201 are distributed in a circular array with the center of the bearing 204 as the center of the array. The brush rod 205 is provided with multiple groups of bristles at the end away from the rotating shaft 203, so that it can clean and conduct the filter screen inside the electromagnetic iron remover 4 during rotation.

[0035] Reference Figure 1 、 Figure 3 as well as Figure 4 The automatic shielding device 3 includes a shielding plate 301, an inner shaft 305 is fixedly connected to the inner side of the shielding plate 301, an outer shaft 302 is rotatably connected to the outer arc surface of the inner shaft 305, a sealing plate 303 is fixedly connected to the outer arc surface of the outer shaft 302, and a limiting block 304 is fixedly connected to the inner side of the shielding plate 301.

[0036] The outer surface of the baffle plate 301 is fixedly connected to the feed port 5 of the electromagnetic iron remover 4, and a rectangular groove is provided on the inner side of the baffle plate 301, so that the outer shaft 302 and the sealing plate 303 can be accommodated on its inner side. A through hole is provided at the center of the inner surface of the outer shaft 302, so that the inner shaft 305 can be accommodated therein. The outer surface of the inner shaft 305 is elastically connected to the outer shaft 302 through a vortex spring, so when there is no feed pressure above, the vortex spring can drive the sealing plate 303 to always be close to the upper limit block 304 through its own elastic force, and the end of the sealing plate 303 away from the outer shaft 302 is set to an arc surface, and the lower end of the limit block 304 is in contact with the sealing plate 303.

[0037] Working principle: When this device is in use, the internal slurry will move from the feed port 5 to the discharge port. At this time, the flowing slurry will drive the impeller 202 at the discharge port of the electromagnetic iron remover 4 to rotate through its flow. When the impeller 202 rotates, it will synchronously drive the rotating shaft 203 to rotate, and the rotating shaft 203 can synchronously drive the brush rod 205 to rotate. At this time, the brush rod 205 will brush off the impurities attached to the internal filter screen of the electromagnetic iron remover 4 during the rotation process, thereby improving the filtering and iron removal effect of this device.

[0038] At the same time, when the feed pressure is lost above the device and the feed pipe needs to be disassembled for equipment maintenance, the sealing plate 303 will be pulled close to the upper limit block 304 due to the elastic force of the volute spring. At this time, the feed port 5 will be in a sealed state, thereby preventing dust and impurities in the external environment from entering the electromagnetic iron remover 4. In the normal feeding process, since there is feed pressure above and the feed pressure is greater than the elastic force of the volute spring, the sealing plate 303 will drive the outer shaft 302 to rotate, thereby automatically releasing the sealing shielding effect on the feed port 5.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
