Description

TECHNICAL FIELD

[0001] The present application relates to a drum, in particular to a magnetic drum. BACKGROUND

[0002] In order to separate ferromagnetic materials and non-ferromagnetic materials, a magnetic separation drum is made. In the traditional magnetic drum, the manufacturing method of the magnetic drum is to install block-shaped permanent magnets inside the drum. The permanent magnets are fixed on the cylindrical magnetic guide plate through the central hole. In order to achieve sufficient magnetic attraction to the outside world, a large number of permanent magnets are used, and the installation is complicated.

[0003] Therefore, there is a need for a magnetic drum with simple installation and fixed magnetic body position. SUMMARY

[0004] In order to overcome the deficiencies mentioned in the background art, one of the purposes of the present application is to provide a magnetic drum for separating ferromagnetic materials and non-ferromagnetic materials.

[0005] One of the purposes of the present application is achieved by adopting the following technical solutions:

[0006] A magnetic drum includes a drum cylinder, a drum end cover, a magnetic rod, and a magnetic base plate. The two end faces of the drum cylinder are covered with a drum end cover. The inner side of the drum end cover is provided with a magnetic base plate. The magnetic base plate is fixed with a magnetic rod through a screw. The magnetic rod is located inside the circumference of the drum cylinder. A fixed shaft is provided inside the drum cylinder, which penetrates the drum end cover and the magnetic base plate. One end of the fixed shaft extends to the outside of the drum end cover and is connected with a fixed shaft seat. The other end extends out and is connected with a drive shaft through a drive shaft bearing seat.

[0007] A threaded hole is formed in the magnetic base plate. The threaded hole and the fixed shaft are threadedly connected.

[0008] A bearing is provided in the drum end cover. One end of the fixed shaft penetrates the bearing and is connected with the fixed shaft seat. The other end penetrates the bearing and is connected with the drive shaft.

[0009] The magnetic rod is arranged along half a circle of the magnetic base plate inside the drum cylinder.

[0010] The magnetic rod is arranged along a full circle of the magnetic base plate inside the drum cylinder.

[0011] The drum cylinder is made of stainless steel or organic glass tube.

[0012] Compared with the prior art, the present application has the following advantages:

[0013] The magnetic rod is used instead of the permanent magnet in the present application, which is fixedly connected with the magnetic base plate through a screw. The installation is simple and convenient, and the magnetic guide plate is simplified. The drum cylinder, the magnetic base plate and the drum end cover are assembled, which is simple in structure and convenient in installation. Attached Figure Description

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0022] Please see Figures 1-6 This invention provides a technical solution: a magnetic roller, comprising a roller body 1, a roller end cap 2, a magnetic rod 4, and a magnetic base plate 5. The roller body 1 is supported by stainless steel or a glass tube. The roller end cap 2 covers both ends of the roller body 1. A magnetic base plate 5 is provided inside the roller end cap 2. The magnetic rod 4 is fixed to the magnetic base plate 5 by screws. The magnetic rod 4 is arranged along a semi-circumference of the magnetic base plate 5. The magnetic rod 4 is located inside the circumference of the roller body 1 and is evenly arranged in a circular array along the inner arc surface of the roller body. A fixed shaft 3 is provided inside the roller body 1, passing through the roller end cap 2 and the magnetic base plate 5. The magnetic base plate 5 is threadedly locked to the fixed shaft 3 by opening a threaded through hole 10. One end of the fixed shaft 3 passes through a bearing 9 inside the roller end cap 2 and is connected to a fixed shaft seat 7. The other end passes through a bearing 9 inside the roller end cap 2 and is connected to a drive shaft 6. The drive shaft 6 is then connected to a drive shaft bearing seat 8.

[0023] The installation steps of the magnetic attraction roller are as follows: the bearing 9 is installed into the roller end cover 2 on both sides, the magnetic rod 4 and the magnetic base plate 5 are fixed by screws, the threaded hole 10 with a 90° position relationship is formed in the magnetic base plate 5, the installed assembly is fixed to the fixed shaft 3, the threaded hole 10 is used to threadedly lock and connect the magnetic base plate 5 and the fixed shaft 3, the roller end cover 2 including the bearing 9 is installed to the fixed shaft 3, the bearing 9 is positioned by the shaft shoulder, the driving shaft 6 is installed outside the fixed shaft 3, the roller barrel 1 and the stop strip are installed between the roller end covers 2, finally, the fixed shaft base 7 is installed outside the fixed shaft 3, and the driving shaft bearing base 8 is installed outside the driving shaft 6.

[0024] After the fixed shaft 3 is fixed on the fixed shaft base 7, the magnetic base plate 5 and the magnetic rod 4 are fixed inside and do not move, the driving shaft 6 is connected to the external driving shaft bearing base 8, the roller barrel 1 can rotate around the internal uniformly distributed magnetic rod 4, when the mixed materials with magnetism and non-magnetism conveyed by the conveying belt fall on the roller barrel 1, the non-magnetic materials fall first with the rotation of the roller barrel, the ferromagnetic materials are attracted to the roller barrel 1 due to the existence of the internal magnetic rod 4 and are rotated along the magnetic circular surface to the lower part, when the roller rotates to the non-magnetic part, the ferromagnetic materials start to fall from the surface of the roller barrel, so that the separation of the two materials is realized.

[0025] The magnetic rod 4 is used instead of the permanent magnet block in the application, the magnetic rod 4 is fixedly connected with the magnetic base plate 5 by screws, the installation is simple and convenient, the magnetic guide plate is simplified, the roller barrel 1 is assembled and installed between the magnetic base plate 5 and the roller end cover 2, the structure is simple, and the installation is convenient.
