[0034] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0035] See also Figures 1 to 4 As shown, a raw coal iron removal device, this embodiment includes:

[0036] The iron removal bucket 1 has openings at both ends, and the iron removal bucket 1 is tilted. The length of the iron removal bucket 1 is selected according to actual needs to ensure that the number of turns of the suction stroke is not too small;

[0037] The rotating assembly 2 is installed on the outer periphery of the iron removal barrel 1;

[0038] A plurality of electromagnets 3 are evenly mounted on the outer periphery of the iron removal barrel 1, and are used to attract the iron impurities in the raw coal in the iron removal barrel 1. The number and position of the electromagnets 3 are selected according to actual needs to ensure the attraction effect of the iron impurities in the raw coal;

[0039] The scraper 4 is obliquely arranged in the inner cavity of the iron removal barrel 1, and is used to scrape the iron impurities on the inner wall of the iron removal barrel 1. The conveying equipment conveys the raw materials into the iron removal barrel 1, and the rotating motor 24 drives the driving gear 25 to rotate, thereby driving the hollow gear 22 to rotate, thereby driving the iron removal barrel 1 to rotate. Since the iron removal barrel 1 is in an inclined state, when it is rotating, the raw coal will move downward along with the rotation, but the iron impurities in the raw coal will be attracted by the electromagnet 3 and stick to the inner wall of the iron removal barrel 1. After rotating one circle, it will be cleaned by the scraper 4.

[0040] The scraper 4 is connected and fixed to the rotating combination 2 through multiple connecting plates 5. The scraper 4 is connected to a vertically arranged assembly plate 6 through multiple connecting blocks. The assembly plate 6 is connected to a linear motor 7. The moving part of the linear motor 7 is connected to a vertically arranged electric push rod 8. The moving part of the electric push rod 8 is connected to a push plate 9 for cleaning. After the scraper 4 has been cleaned for a period of time, the linear motor 7 is controlled to drive the push plate 9 to a high place, and the electric push rod 8 is controlled to extend so that the push plate 9 is against the scraper 4 and the iron removal bucket 1. The linear motor 7 drives the electric push rod 8 to move, and then drives the push plate 9 to move, so as to push away the iron impurities cleaned by the scraper 4, and after being blocked by the arc plate 10, it falls under the scraper.

[0041] Rotation combination 2 includes:

[0042] Two bearings 21 are rotatably connected to the iron removal bucket 1 and are arranged on both sides of the plurality of electromagnets 3;

[0043] Two hollow gears 22 are fixedly mounted on the outer circumference of the iron removal barrel 1;

[0044] The two bearings 21 are commonly connected to a car plate 23, and a rotating motor 24 is installed on the car plate 23 through a motor seat. The output shaft of the rotating motor 24 is connected to a driving gear 25 meshing with the hollow gear 22. The conveying equipment transports the raw materials into the iron removal barrel 1, and the rotating motor 24 drives the driving gear 25 to rotate, thereby driving the hollow gear 22 to rotate, thereby driving the iron removal barrel 1 to rotate. Since the iron removal barrel 1 is in a tilted state, when it is rotating, the raw coal will move downward along with the rotation.

[0045] In order to adjust the tilt angle, a plurality of hollow tubes 26 are installed at the bottom end of the vehicle plate 23, and the inner cavity of the hollow tubes 26 is provided with support legs 27. The bottom end of the vehicle plate 23 is also connected to a hydraulic rod 28, and the moving part of the hydraulic rod 28 and the bottom end of the support leg 27 are both provided with brake casters 29. A threaded channel is provided on the side of the hollow tube 26, and an adjusting threaded rod 210 is threadedly connected to the threaded channel. A plurality of circular holes for the adjusting threaded rod 210 to pass through are provided on the side of the support leg 27.

[0046] In order to facilitate subsequent material gathering, the side of the scraper 4 is fixedly connected with an arc plate 10 which is slidably connected to the iron removal bucket 1, and the curvature of the arc plate 10 is the same as that of the iron removal bucket 1, and a material receiving device is installed at the arc plate 10.

[0047] A U-shaped material receiving plate 211 corresponding to the position of the iron removal barrel 1 is connected to the top of the vehicle plate 23 , and two inclined material gathering plates 212 are connected to the inner wall of the material receiving plate 211 , and a material receiving device is installed at the material gathering plate 212 .

[0048] The electromagnet 3, linear motor 7, electric push rod 8, rotary motor 24, and hydraulic rod 28 are all conventional instruments. Their working principles, sizes, and models are irrelevant to the problems solved by the present application, so they will not be described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0049] In addition, the electromagnet 3, the linear motor 7 and the electric push rod 8 are attached to the rotating iron removal barrel 1, so it is preferred to have a built-in battery and a remote control switch, and there is no need to connect external wires to the outside to avoid affecting the rotation.

[0050] How it works

[0051] In the raw coal deironing device, the conveying equipment conveys the raw materials into the deironing barrel 1, and the rotating motor 24 drives the driving gear 25 to rotate, thereby driving the hollow gear 22 to rotate, thereby driving the deironing barrel 1 to rotate. Since the deironing barrel 1 is in an inclined state, the raw coal will move down along with the rotation when it rotates, but the iron impurities in the raw coal will be attracted by the electromagnet 3 and stick to the inner wall of the deironing barrel 1. After rotating one circle, it will be cleaned by the scraper 4;

[0052] After being processed, the raw coal falls onto the receiving plate 211, and falls after being gathered by the gathering plate 212. After the scraper 4 cleans for a period of time, the linear motor 7 is controlled to drive the pushing plate 9 to a high place, and the electric push rod 8 is controlled to extend, so that the pushing plate 9 is against the scraper 4 and the iron removal bucket 1. The linear motor 7 drives the electric push rod 8 to move, and then drives the pushing plate 9 to move, pushing away the iron impurities cleaned by the scraper 4, and after being blocked by the arc plate 10, it falls under the scraper.
