[0019] This application provides a high-efficiency iron removal and recycling device. The first discharge port 12 includes a first filter screen 15, which is used to block large iron filings from being discharged from the first discharge port 12 along with cement due to gravity.

[0020] This application provides a high-efficiency iron removal and recovery device. The second discharge port 21 further includes a second filter screen 24. The second filter screen 24 is a magnetic filter screen, which can adsorb a portion of the iron filings impurities mixed in the cement raw materials, just like the second recovery pipe 221, thereby improving the iron removal effect.

[0021] This application provides a high-efficiency iron removal and recovery device, wherein the mesh density of the second filter screen 24 is greater than the mesh density of the first filter screen 15.

[0022] This application provides an efficient iron removal and recycling device, wherein the second recycling unit includes a second recycling pipe 221, a second conductive coil 222, and a second recycling bucket 223.

[0023] This application provides an efficient iron removal and recycling device, wherein the second recycling pipe 221 is a stainless steel pipe, the second conductive coil 222 is disposed on the outer wall of the second recycling pipe 221, and the second recycling bucket 223 is disposed at the outlet end of the second recycling pipe 221.

[0024] This application provides a high-efficiency iron removal and recycling device. The third iron removal unit 3 is separately arranged below the second iron removal unit 2 relative to the first iron removal unit 1 and the second iron removal unit 2. When the recycling device is working, the third iron removal unit 3 is provided with a cement recycling bucket directly opposite the second discharge port 21.

[0025] This application provides a high-efficiency iron removal and recycling device. After the recycling device has finished working, the third iron removal unit 3 is provided with an iron scrap recycling bin facing the second discharge port 21.

[0026] This application provides a high-efficiency iron removal and recovery device, comprising at least two of the aforementioned crushing shafts. It is understood that the more crushing shafts there are, the more dispersed and uniform the cement raw materials are mixed, which is more conducive to the recovery of iron filings and impurities. Figure 1 It includes a first crushing shaft 131 and a second crushing shaft 132.

[0027] This application provides a high-efficiency iron removal and recycling device, wherein the motor 133 is directly connected to one of the crushing shafts. In one embodiment, one crushing shaft is directly connected to the motor 133, while the other crushing shafts are indirectly connected to the motor 133 via belts, sprockets, gears, or couplings.

[0028] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly explained below in conjunction with specific application scenarios: Specifically, when the iron removal and recycling device is ready to start working, it is activated, the first recycling pipe 141, the second recycling pipe 221 and the first recycling bin 143 are energized, the motor 133 is started, the crushing shaft begins to rotate, and the cement raw material is poured into the first-stage iron removal unit 1 from the first feed inlet 11. Under the stirring of the crushing shaft, large lumps and clumps of raw material are broken into fine and uniform raw material in the first-stage iron removal unit 1. Impurities containing iron filings are adsorbed by the first recycling pipe 141 under the action of the magnetic field. Since the surface area and the amount of magnetic material used in the first recycling bin 143 are greater than those in the first recycling pipe 141, the magnetic field strength of the first recycling bin 143 is greater than that of the first recycling pipe 141. Therefore, iron filings and impurities enter the first recycling bin 143 from the first recycling pipe 141 and are directly recycled by the first recycling bin 143, which is convenient, simple and requires no manual operation.

[0029] Furthermore, cement and fine iron filings that are not adsorbed by the first recycling pipe 141 are discharged from the first outlet 12 through the first filter screen 15 to the secondary iron removal unit 2. Due to the filtration by the first filter screen 15, the cement raw material entering the secondary iron removal unit 2 has a smaller particle size. When the smaller particle size raw material is filtered by the second filter screen 24, it enters the raw material recycling bin. The fine iron filings mixed in the cement raw material are adsorbed in the second filter screen 24, the second recycling pipe 221, or the second recycling bin 223. The cement raw material bin in the third iron removal unit 3 can then obtain clean cement raw material. After the cement raw material is discharged from the second outlet 21, the cement recycling bin is removed, and the iron filings recycling bin is placed directly below the second outlet 21. The power supply of the recycling device is disconnected, so that the iron filings retained on the second filter screen 24 fall into the iron filings recycling bin and are recycled by the iron filings recycling bin.

[0030] Furthermore, any cement raw materials and impurities that are not completely removed from the primary iron removal unit 1 and the secondary iron removal unit 2 can also be cleaned through the first recovery pipe 141 and the second recovery pipe 221, to prevent cement raw materials from clogging the recovery device at the first filter screen 15 or the second filter screen 24, thus affecting subsequent production and processes.

[0031] This application provides a high-efficiency iron removal and recovery device, comprising at least: a primary iron removal unit 1, a secondary iron removal unit 2, and a tertiary iron removal unit 3; the primary iron removal unit 1 includes a first cavity, a crushing shaft, a first feed inlet 11, a first discharge outlet 12, and a first recovery unit; the crushing shaft passes through the first cavity, and a motor 133 is provided at one end of the crushing shaft; the first discharge outlet 12 is located on the side of the first cavity near the ground, the first feed inlet 11 is directly opposite the first discharge outlet 12, and the first recovery unit is located on the side of the first cavity adjacent to the first discharge outlet 12; the first recovery unit includes a first... The system includes a recycling pipe 141 and a first recycling bin 143. The first recycling pipe 141 is a stainless steel pipe, and its outer wall contains a conductive coil. The first recycling bin 143 is an electrically conductive magnetic bin, located at the outlet end of the first recycling pipe 141. The secondary iron removal unit 2 includes a second cavity, a second inlet, a second outlet 21, and a second recycling unit. The second cavity is connected to the first outlet 12, the second inlet coincides with the first outlet 12, and the second outlet 21 is directly opposite the first outlet 12. The second recycling unit... The first-stage iron removal unit 3 is located adjacent to the second discharge port 21. The third iron removal unit 3 is separately located directly below the second iron removal unit 2, relative to the first iron removal unit 1 and the second iron removal unit 2. The third iron removal unit 3 includes a cement recycling bin and an iron filings recycling bin. Its advantages are: firstly, the iron removal and recycling device includes three iron removal units, each of which includes a recycling unit, allowing for the recycling of iron filings while removing iron, resulting in strong iron removal and high recycling efficiency; secondly, the first-stage iron removal unit 1 includes the crushing shaft and the first-stage recycling unit, which includes a first recycling pipe 141 and... The first recycling bin 143 has a conductive coil on its outer wall. The first recycling bin 143 is an electrically energized magnetic bin. When the first recycling pipe 141 is energized, iron filings are attracted from the first-stage iron removal unit 1 to the first recycling pipe 141. Since the first recycling bin 143 is an electrically energized magnetic bin, when the first recycling bin 143 is energized, the magnetic force of the first recycling bin 143 is greater than the magnetic force of the first recycling pipe 141. Iron filings and impurities are absorbed from the first recycling pipe 141 to the first recycling bin 143, achieving automated iron removal with high efficiency.
