Technical Field

[0001] The utility model relates to the technical field of magnetic material crushing and screening, in particular to a magnetic material crushing and pre-screening device. Background Art

[0002] Magnetic materials, commonly referred to as magnetic materials, refer to strong magnetic substances. They are ancient functional materials with a wide range of uses. Magnetic materials refer to substances that produce magnetism by combining iron, cobalt, nickel and their alloys. In the process of producing magnetic products, it is necessary to first prepare the materials, then press them into shape, process them after firing, and finally inspect the finished products. The quality of the raw materials processed in the material preparation process affects the performance of the manufactured products. In the process of magnetic material processing, the magnetic materials need to be crushed and stirred, but now they are crushed and stirred separately, and the crushing equipment used is relatively single, which leads to the problem of uneven crushing, making it difficult to obtain high-quality magnetic raw materials, and reducing the working effect. To this end, we propose a magnetic material crushing pre-screening device. Utility Model Content

DETAILED DESCRIPTION

[0017] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0018] like Figure 1-3 As shown, the utility model is a magnetic material crushing and pre-screening device, including a kettle body 1, two groups of cross-arranged stirring mechanisms are arranged inside the kettle body 1, the stirring mechanism includes a stirring shaft 14 and a plurality of stirring paddles 15 arranged on the side of the stirring shaft 14, and the top of the stirring shaft 14 is connected to a gear 16. By arranging two groups of stirring mechanisms with cross-working areas inside the kettle body 1, the two groups of stirring mechanisms can be driven by a first motor 17 under the cooperation of the two groups of gears 16 to stir and crush the materials, thereby effectively improving the stirring effect of the materials.

[0019] A screen 19 is provided at the lower side of the stirring mechanism. The screen 19 is arranged at an angle, and the outlet of the screen 19 is provided in the grinding chamber 21. By providing the screen 19, the preliminarily crushed material can be screened, and the qualified material falls through the screen 19 and is discharged through the discharge port 13. Under the vibration of the screen 19, the larger material enters the grinding chamber 21.

[0020] A second motor 22 is arranged on the top of the grinding chamber 21, and a rotating shaft 23 is connected to the output end of the second motor 22, and a grinding wheel 24 is installed on the side of the rotating shaft 23. The outlet of the grinding chamber 21 is connected to the inner cavity of the kettle body 1 through a reflux pipe 26, and a powerful fan 27 is arranged on the reflux pipe 26. Under the action of the second motor 22, the rotating shaft 23 and the grinding wheel 24, the material is extruded and ground so that the material is fully crushed, and then the material is introduced into the kettle body 1 again for stirring under the action of the powerful fan 27, and the above steps are repeated until the magnetic material is thoroughly crushed, thereby effectively ensuring the processing quality of the material.

[0021] In the above scheme, a feed hopper 11 is arranged on the top of the kettle body 1, and a discharge port 13 is arranged on the bottom of the kettle body 1. A valve is arranged on the discharge port 13. During operation, magnetic material is added through the feed hopper 11, and the processed and crushed material is discharged through the discharge port 13.

[0022] In the above solution, support columns 12 are arranged at the lower side of the kettle body 1 . Specifically, at least three groups of support columns 12 are arranged to form a stable support mechanism, and the kettle body 1 is stably supported by the support columns 12 .

[0023] In the above scheme, the two gears 16 mesh with each other, and a first motor 17 is connected to the top of one of the gears 16. The shell of the first motor 17 is fixedly installed on the top of the kettle body 1. The first motor 17 and the second motor 22 are both forward and reverse motors, and the two are connected to the power supply and control switch through wires.

[0024] In the above scheme, blowers 18 are provided on both sides of the kettle body 1. By arranging the blowers 18 alternating left and right on the falling path of the material, the magnetic material can be continuously blown to alternate left and right, so that the material is in more complete contact with the stirring mechanism, thereby improving the stirring uniformity of the material.

[0025] In the above scheme, the screen 19 is hinged to the inner wall of the kettle body 1, and the screen 19 includes an external bracket and an internal screen body. The screen body is connected to the bracket through a spring, and a vibration motor 2 is connected to the lower side of the screen 19. The vibration motor 2 is externally connected to a switch and a power supply. Under the action of the vibration motor 2, the screen body is driven to vibrate in different directions.

[0026] In the above scheme, the end of the grinding wheel 24 is gap-fitted with the grinding chamber 25 to form a spiral channel therebetween. A guide plate 28 is provided below the grinding chamber 25 to facilitate the material to enter the return pipe 26 from the opening.

[0027] Working principle:

[0028] When the magnetic material crushing and pre-screening device is used, the magnetic material to be crushed is added from the top of the feed hopper 11 into the kettle body 1. At this time, the gear 16 connected to the first motor 17 is driven to rotate, and the other gear rotates accordingly, so that the two sets of stirring mechanisms rotate at the same time, and the materials are crushed and stirred and mixed under the action of the stirring paddle 15. Since the two sets of stirring mechanisms have overlapping processing areas, the materials can be fully processed, and in the process of the material falling, the airflow generated by the blowers 18 arranged on both sides of the kettle body 1 enters the inner cavity of the kettle body 1 from different directions to blow the magnetic material, thereby expanding the contact range between the material and the stirring mechanism. The initially crushed material falls on the upper side of the screen 19, and at this time, the screen 19 is driven to vibrate under the action of the vibration motor 2 to screen the material, while the larger material is guided into the grinding chamber 21, and at this time, the second motor 22 drives the rotating shaft 23 and the grinding wheel 24 to rotate continuously, so that the material is crushed under the action of the grinding wheel 24 and the grinding chamber 25, and then the crushed material is sucked into the kettle body 1 through the reflux pipe 26 under the action of the strong fan 27 to repeat the above-mentioned stirring process, and the material with a size smaller than the mesh diameter of the screen 19 is discharged from the discharge port 13 after falling, thereby achieving the crushing and screening effect of the magnetic material.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
