However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

A filter cartridge 6 is fixedly arranged at the bottom of the clamping ring 5, a rotating drum 7 rotatably connected thereto is inserted at the bottom of the screening drum 1, the top of the rotating drum 7 passes through the screening drum 1 and is fixedly connected to a bottom plate 8 which closes the bottom of the filter cartridge 6, a rotating rod 9 is arranged inside the rotating drum 7, the top of the rotating rod 9 extends to the inner side of the filter cartridge 6, a rotating disk 10 is fixedly sleeved on the outer wall of the rotating rod 9 from top to bottom, and a motor 11 is arranged at the bottom of the screening drum 1, and the motor 11 is used to drive the rotating drum 7 and the rotating rod 9 to rotate.

[0033] In this embodiment, the edge of the top of the base plate 8 is fixedly connected with positioning rods 12 distributed in a circular array, and the bottom of the filter cartridge 6 is provided with a plurality of positioning holes 13 adapted to the positioning rods 12. The positioning rods 12 can be inserted into the corresponding positioning holes 13 to realize the connection between the filter cartridge 6 and the base plate 8.

[0034] By adopting the above technical solution, the positioning rod 12 can be inserted into the positioning hole 13 when the filter cartridge 6 and the bottom plate 8 are connected. Therefore, when the bottom plate 8 rotates, the filter cartridge 6 can be driven to rotate by the positioning rod 12 for screening.

[0035] In this embodiment, a sealing ring 14 is embedded in the outer ring of the bottom plate 8 , and when the bottom plate 8 and the filter cartridge 6 are connected, the sealing ring 14 fits against the inner wall of the filter cartridge 6 .

[0036] By adopting the above technical solution, the sealing ring 14 is used to seal the bottom plate 8 and the filter cartridge 6 when they are connected, so as to prevent the slag from passing through between the filter cartridge 6 and the bottom plate 8 without being screened.

[0037] In this embodiment, the bottom of the screening drum 1 is fixedly connected to a support plate 15, the motor 11 is fixedly installed at the bottom of the support plate 15, the bottom end of the rotating rod 9 is rotatably connected to the support plate 15, the output shaft of the motor 11 passes through the support plate 15 and is fixedly sleeved with a main sprocket 16 and a main gear 17 from top to bottom, a secondary sprocket 18 is fixedly sleeved on the outer wall of the bottom end of the rotating drum 7, a chain 19 is arranged for transmission between the secondary sprocket 18 and the main sprocket 16, and a secondary gear 20 meshing with the main gear 17 is fixedly sleeved on the outer wall of the bottom end of the rotating rod 9.

[0038] By adopting the above technical solution, the motor 11 drives the rotating drum 7 to rotate through the main sprocket 16, the chain 19 and the auxiliary sprocket 18. The rotating drum 7 rotates the filter screen through the bottom plate 8 to generate centrifugal force for screening. The motor 11 also drives the rotating rod 9 to rotate through the main gear 17 and the auxiliary gear 20. The rotating rod 9 drives the turntable 10 to stir the slag and absorb the magnetic part therein, and the rotating rod 9 and the rotating drum 7 have opposite directions.

[0039] In this embodiment, a sealed bearing is provided between the rotating rod 9 and the rotating drum 7 , the outer ring of the sealed bearing is fixedly connected to the inner wall of the rotating drum 7 , and the inner ring of the sealed bearing is fixedly connected to the outer wall of the rotating rod 9 .

[0040] By adopting the above technical solution, the arrangement of the sealed bearing ensures that the rotation of the drum 7 and the rotating rod 9 does not affect each other, and the rotating rod 9 and the drum 7 are sealed to prevent slag from passing through.

[0041] In this embodiment, a top cover 21 that can close the top of the feed pipe 4 is hingedly installed at the top of the feed pipe 4 through a hinge, and a lifting cylinder 22 is hingedly installed between the side of the top cover 21 and the side of the feed pipe 4.

[0042] By adopting the above technical solution, the lifting cylinder 22 pushes the top cover 21 to open and close. During the screening process, the top cover 21 can close the feed pipe 4, thereby reducing the escape of dust and powder generated by the slag during screening and avoiding impact on the surrounding environment.

[0043] In this embodiment, the turntable 10 is a circular electromagnetic suction cup and has a switch. The turntable 10 is tilted and the tilt angle is 15°-35°.

[0044] By adopting the above technical solution, when the turntable 10 is turned on and powered on, the magnetic part of the fallen slag can be adsorbed, and the non-magnetic part can be thrown out by cooperating with the rotation of the filter cartridge 6. Its inclined setting can not only improve the stirring effect, but also allow the magnetic part to fall along the inclined angle when the power is off, which is convenient for collection.

[0045] In this embodiment, a terminal controller 23 is installed on the front of the screening drum 1 , and the terminal controller 23 is electrically connected to and controls the switches of the lifting cylinder 2 , the motor 11 , the lifting cylinder 22 and the turntable 10 .

[0046] By adopting the above technical scheme, the terminal controller 23 controls the lifting cylinder 2 to connect and separate the filter cartridge 6 and the bottom plate 8, controls the motor 11 to realize centrifugal screening and stirring, controls the lifting cylinder 22 to open and close the top cover 21, and controls the switch of the turntable 10 to turn on and off the power. The terminal controller 23 can be programmed accordingly in advance to make the entire device intelligent and automated.

[0047] How to use and working principle of this device:

[0048] When the device is in use, the terminal controller 23 is first used to control the lifting cylinder 2 to extend and push the top plate 3, and the top plate 3 drives the filter cartridge 6 to move downward through the clamp ring 5. The positioning hole 13 at the bottom of the filter cartridge 6 corresponds to the positioning rod 12 on the bottom plate 8. As the filter cartridge 6 moves downward, the positioning rod 12 enters the positioning hole 13. At this time, the sealing ring 14 is attached to the inner wall of the filter cartridge 6 and the top cover 21 is in an open state.

[0049] Subsequently, the slag to be screened is introduced into the space formed by the top plate 3, the filter cartridge 6 and the bottom plate 8 through the feed pipe 4. After the slag is injected, the terminal controller 23 controls the lifting cylinder 22 to push and pull the top cover 21 to close the feed pipe 4. This is to prevent the dust and powder generated by the slag in the subsequent screening process from escaping and affecting the surrounding environment.

[0050] Then, the terminal controller 23 controls the motor 11 to start and the turntable 10 to be energized, the main sprocket 16 and the main gear 17 on the output shaft of the motor 11 rotate, the main sprocket 16 drives the drum 7 to rotate through the chain 19 and the auxiliary sprocket 18, the drum 7 drives the bottom plate 8 to rotate the filter screen to generate centrifugal force to screen the slag, and at the same time the main gear 17 drives the rotating rod 9 to rotate through the auxiliary gear 20 and the direction is opposite to that of the drum 7, the rotating rod 9 drives the turntable 10 to rotate, the turntable 10 stirs the slag, through the dual effects of centrifugation and stirring, the slag can continue to move and turn over, so that the slag has more opportunities to contact the filter cartridge 6 and is evenly distributed on the filter cartridge 6, reducing the possibility of the slag remaining on the surface of the filter cartridge 6, thereby screening the slag faster and improving the overall screening efficiency. In this process, the turntable 10 is energized to absorb the magnetic part in the ore, has a magnetic separation function, and effectively screens the magnetic minerals contained in the slag for reuse;

[0051] Finally, after the screening is completed, the slag that passes through the filter cartridge 6 is directly discharged from the discharge port for collection, and then the lifting cylinder 2 lifts the filter cartridge 6 and separates it from the bottom plate 8, and the large particles of slag in the filter cartridge 6 fall from the gap between the filter cartridge 6 and the bottom plate 8 for separate collection, and then the turntable 10 can be powered off, and the magnetic part adsorbed thereon falls along the inclination angle for collection. Therefore, after screening, the slag with larger particle sizes and magnetic slag are cleaned and collected, and the slag in the filter cartridge 6 is effectively cleaned to prevent the large particle size slag accumulated in the filter cartridge 6 from affecting the subsequent screening.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
