[0029] The present invention is further described below by way of embodiments in conjunction with the accompanying drawings.

[0030] like Figure 1-Figure 8As shown, an iron removal device for recycling aluminum chips includes a frame 1 which can provide installation positions for various components to enable the device to operate stably, a iron removal component 2 which can continuously remove iron from aluminum chips is arranged on the frame 1, a feeding component 3 which can hold aluminum chips and allow them to fall into the iron removal component 2 is arranged above the iron removal component 2, and a discharging component 4 which can respectively receive the aluminum chips and iron impurities that have been deironed is arranged below the iron removal component 2.

[0031] In this embodiment: the iron removal component 2 includes a transverse moving part that can receive the aluminum chips to be removed and make them fall in a fixed area, a magnetic suction part that can remove iron impurities in the aluminum chips, and a rotating part that can drive the aluminum chips that fall into the transverse moving part to rotate. The transverse moving part includes a support rod 201 fixedly installed in the frame 1, a hydraulic rod 202 is fixedly installed on one side of the frame 1, and a silo 203 is movably connected between the support rods 201. The magnetic suction part includes a mounting frame 204 fixedly connected to the outer side of the silo 203, and an electromagnetic iron absorption plate 205 is fixedly installed in the mounting frame 204. The rotating part includes a shaft seat 206 fixedly connected to both sides of the frame 1, and a rotating shaft 207 is movably connected between the shaft seats 206. A motor 208 is fixedly connected to one end of the rotating shaft 207, and a rotating drum 209 is fixedly connected to the outer side of the rotating shaft 207. A partition 210 is fixedly installed on the rotating drum 209. The iron removal component 2 also includes a limit ring 211 fixedly connected to both sides of the silo 203;

[0032] The support rod 201 and the rotating drum 209 are both slidably connected to the silo 203, and the shaft seat 206 is rotatably connected to the rotating shaft 207;

[0033] The silo 203 is installed by the support rod 201 and can slide and move horizontally in the device. The length change of the telescopic end of the hydraulic rod 202 is transmitted to the silo 203 through the limit ring 211 connected to the hydraulic rod 202, so that the hydraulic rod 202 drives the silo 203 to move horizontally. The silo 203 provides an installation position for the mounting frame 204 equipped with the electromagnetic iron plate 205, and cooperates with the rotating drum 209 to form a relatively closed space, so that the aluminum chips dropped by the feeding assembly 3 can be The rotating drum 209 is installed through the rotating shaft 207 installed in the frame 1 by the shaft seat 206, and the rotation of the output end of the motor 208 is transmitted to the rotating drum 209. The annular material receiving area on the outer side of the rotating drum 209 is divided into equal parts by the partition plate 210, and the limiting rings 211 connected to the two sides of the silo 203 are used to prevent the silo 203 from moving excessively and separating from the rotating drum 209.

[0034] In this embodiment: the feed assembly 3 includes a feed hopper 301 fixedly mounted above the frame 1, a feed cover 302 is movably connected to the discharge end of the feed hopper 301, a support 303 is fixedly connected to the frame 1, and a cylinder 304 is provided between the feed cover 302 and the support 303;

[0035] The feed hopper 301 and the cylinder 304 are both rotatably connected to the feed cover 302, and the support 303 is rotatably connected to the cylinder 304; the aluminum chips to be deironed are placed in the feed hopper 301, the feed cover 302 is used to control the opening and closing of the discharge end of the feed hopper 301, the support 303 is used to limit the position of one end of the cylinder 304, and the feed cover 302 is driven to rotate relative to the feed hopper 301 through the change in the length of the telescopic end of the cylinder 304, thereby controlling the falling of the aluminum chips in the feed hopper 301.

[0036] In this embodiment: the unloading component 4 includes a first guide hopper 401 fixedly installed in the frame 1, and a second guide hopper 402 is fixedly connected to the first guide hopper 401; the aluminum chips that have been deironed are received by the second guide hopper 402 located directly below the rotating drum 209, and the first guide hopper 401 with openings located on both sides of the second guide hopper 402 receives the iron impurities sucked out by the electromagnetic iron absorption plate 205, and the first guide hopper 401 and the second guide hopper 402 can respectively guide the aluminum chips and iron impurities that have been deironed to different directions of the device, thereby avoiding the two from mixing again.

[0037] Working principle: When the device is installed to remove iron for aluminum scrap recovery, when one side of the rotating drum 209 is fitted with the limiting ring 211 on one side of the silo 203, the motor 208 is driven to drive the rotating drum 209 to rotate in the silo 203, and the cylinder 304 is driven to pull the feed cover 302, so that the feed cover 302 is turned outward relative to the feed hopper 301, so that the aluminum scraps in the feed hopper 301 can fall onto the continuously rotating rotating drum 209 through the feed end above the silo 203. Under the action of the continuous rotation of the rotating drum 209 and the partition 210, the aluminum scraps will be divided into equal parts and rotate with the rotating drum 209 and the partition 210 until they fall into the second guide hopper 402 through the discharge end below the silo 203 and leave the device. In this process, the equally divided aluminum scraps will pass through the vicinity of the electromagnetic iron absorption plate 205 after the power is turned on, so that the electromagnetic iron absorption plate 205 can absorb the iron impurities in the aluminum scraps.

[0038] After the device has been working for a certain period of time, if the iron impurities adsorbed on the electromagnetic iron plate 205 need to be removed, the cylinder 304 can be temporarily reset to the feed cover 302 to stop the feed hopper 301 from dropping materials. After that, while the drum 209 continues to rotate to fully discharge the remaining aluminum chips in the iron removal component 2, the hydraulic rod 202 is driven to drive the bin 203 to move horizontally relative to the support rod 201 and the drum 209, so that the other side of the drum 209 is fitted with the limit ring 211 on the other side of the bin 203, so that the bin 203 and the drum 209 form a space for accommodating the falling aluminum chips again, and then the above steps can be repeated to continue the iron removal process of the aluminum chips;

[0039] Since the electromagnetic iron-absorbing plate 205 originally corresponding to the position of the rotating drum 209 is now located on the side outside the rotating drum 209, after the corresponding electromagnetic iron-absorbing plate 205 is powered off, the adsorbed iron impurities will quickly fall through the discharge end of the silo 203 located above the first guide hopper 401 and leave the device along the first guide hopper 401.

[0040] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
