Description

Technical Field

[0002] Refractory materials are widely used in the field of metallurgy. They refer to a type of inorganic non-metallic materials with a refractoriness of not less than 1580℃. In the steel plant environment, during the processing of refractory materials, if iron filings are mixed into the raw materials, even in trace amounts, it will have a great impact on the high temperature resistance of the refractory materials. Therefore, the raw materials need to be deironed. Deironing, as the name suggests, means removing iron and other magnetic substances from the raw materials.

[0004] However, the refractory magnetic separation device still has the following problems during actual use:

[0005] In the process of magnetic separation and iron removal of raw materials by the refractory material magnetic separation device, when the raw materials fall on the magnetic separation drum, the raw materials fall with the rotation of the magnetic separation drum, and the iron or magnetic substances mixed in the middle or top of the raw material pile are blocked by other raw materials and may fall with the raw materials, resulting in the iron removal effect being affected, and other raw materials that subsequently fall on the magnetic separation drum may impact the iron or magnetic substances adsorbed on the magnetic separation drum, and the iron or magnetic substances that fall due to the impact will also be mixed into the raw materials, further affecting the iron removal effect on the refractory materials.

[0029] Additional aspects and advantages of the present invention will be further described below in conjunction with the accompanying drawings, and some will become apparent from the following description or be learned through practice of the present invention.

[0030] like Figure 1-3 As shown, an iron removal device for refractory material production comprises a shell 1, on which an iron removal mechanism 2 is arranged, and at the bottom of the shell 1 a first lower hopper 3, a second lower hopper 4 and supporting legs 5 are arranged.

[0031] like Figure 3 and Figure 4 As shown, a feed port 101 is provided at the top of the shell 1, a first discharge port 102 and a second discharge port 103 are provided at the bottom of the shell 1, the position of the first lower hopper 3 corresponds to the position of the first discharge port 102, the position of the second lower hopper 4 corresponds to the position of the second discharge port 103, a first guide plate 106 and a second guide plate 107 are provided inside the shell 1, and a first bearing 108 and a second bearing 109 are provided on the shell 1.

[0032] like Figure 5 As shown, the iron removal mechanism 2 includes a magnetic separation component 21, a transmission belt 22 and a flipping component 23. The flipping component 23 is connected to the magnetic separation component 21 through the transmission belt 22 (in this embodiment, the transmission method is belt drive, but it is not limited to it).

[0033] like Figure 4 As shown, an observation window 104 for observing and repairing the flip assembly 23 is provided on one side of the housing 1 , and a side door 105 for repairing the magnetic separation assembly 21 is provided on the side of the housing 1 away from the observation window 104 .

[0034] like Figure 5 As shown, the magnetic separation component 21 includes a driving member 211, a magnetic separation roller 212 and a first transmission wheel 213. The driving member 211 is fixedly mounted on the outer shell 1. The output end of the driving member 211 is provided with a magnetic separation roller 212. The magnetic separation roller 212 is rotatably connected to the inside of the outer shell 1 through a first bearing 108. The magnetic separation roller 212 is located between the side door 105 and the second material guide plate 107. The first transmission wheel 213 is provided at the end of the magnetic separation roller 212 away from the driving member 211.

[0035] like Figure 5 As shown, the flipping assembly 23 includes a connecting shaft 231, a flipping blade 232 and a second transmission wheel 233. The connecting shaft 231 is rotatably connected to the inside of the shell 1 through the second bearing 109. The flipping blade 232 is arranged on the connecting shaft 231. The connecting shaft 231 and the flipping blade 232 are located between the observation window 104 and the second guide plate 107. A second transmission wheel 233 is arranged at one end of the connecting shaft 231. The second transmission wheel 233 is connected to the first transmission wheel 213 through the transmission belt 22.

[0036] The working process is as follows:

[0037] S1. When in use, add refractory raw materials into the shell 1 from the feed port 101;

[0038] S2, start the driving member 211, the driving member 211 drives the magnetic separation roller 212 to rotate, the magnetic separation roller 212 drives the first transmission wheel 213 to rotate, the first transmission wheel 213 drives the second transmission wheel 233 to rotate through the transmission belt 22, and the second transmission wheel 233 drives the flapping blade 232 to rotate through the connecting shaft 231;

[0039] S3, the raw material falls onto the second guide plate 107 along the first guide plate 106, and then moves along the second guide plate 107, the iron and magnetic substances in the raw material are adsorbed by the magnetic separation roller 212 and stick to the second guide plate 107, and the raw material without iron is located above the iron and magnetic substances;

[0040] S4. When the raw material passes through the turning assembly 23, the rotating turning assembly 23 turns the raw material, making the raw material looser, and at the same time, the iron mixed in the middle and top of the raw material is turned out, so that it is adsorbed on the second guide plate 107, so as to avoid the situation that the iron or magnetic material mixed in the middle or top of the raw material pile is blocked by other raw materials and falls with the raw material, thereby ensuring the iron removal effect of the raw material;

[0041] S5. At the same time, the rotation direction of the flipping assembly 23 is opposite to the direction in which the raw material slides down, which can reduce the speed at which the raw material slides down along the second guide plate 107. The iron and magnetic substances in the raw material move along the second guide plate 107 with the rotation of the magnetic separation roller 212, and the moving direction is the same as the moving direction of the raw material, which further reduces the relative speed between the subsequent raw material and the iron and magnetic substances attached to the second guide plate 107 when falling, thereby reducing the impact force on the iron and magnetic substances adsorbed on the second guide plate 107, avoiding the iron and magnetic substances adsorbed on the second guide plate 107 from being impacted and dropped due to the large impact force of the subsequent raw material, and further ensuring the iron removal effect on the refractory raw material;

[0042] S6. After iron removal, the raw material falls from the first discharge port 102 into the first lower hopper 3 under the action of gravity and inertia. The iron and magnetic substances in the raw material fall from the second discharge port 103 into the second lower hopper 4 along the second guide plate 107 under the attraction of the magnetic separation roller 212, thereby completing the iron removal of the refractory raw material.

[0043] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
