Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1-5, a magnetic separator comprises a housing 1, a rotatable magnetic separation disc 3 is arranged in the housing 1, a fixing plate 7 is fixedly connected to one side of the housing 1, a motor 12 is disposed on the fixing plate 7, a feed hopper 2 is fixedly connected to the housing 1, a material distribution portion 5 is fixed to a side wall of the feed hopper 2, the material distribution portion 5 penetrates through the feed hopper 2, an upper end surface of the material distribution portion 5 is of an inverted V-shaped structure, when a raw material bundle contacts the material distribution portion 5, an upper end surface of the material distribution portion 5 can distribute the raw material bundle, and an inner wall of the feed hopper 2 contacting the raw material is of an arc-shaped structure with a convex middle and two concave sides; a protective cover 8 is fixedly connected to the fixed plate 7, the protective cover 8 is wrapped outside the motor 12, and a fan 10 capable of freely rotating is further arranged in the protective cover 8.

When this device used, inside the raw materials entered into this device by feeder hopper 2, at the in-process that the raw materials fell, raw materials and branch 5 mutual contacts of material portion, and branch 5 shunts the raw materials, has avoided the raw materials to concentrate the middle part that falls at magnetic separation dish 3. When the motor 12 rotates, the rotating shaft 9 starts to rotate, the rotating shaft 9 drives the fan 10 to rotate at the moment, and the fan 10 can blow outside air into the protective cover 8 when rotating, so that the heat dissipation efficiency of the motor 12 is accelerated. When the device is used, the protective cover 8 can protect the motor 12 to a certain degree, so that the problems of direct solar radiation and dust pollution are avoided.

The number of the material distributing parts 5 is three, the three material distributing parts 5 are parallel to each other and are evenly distributed at intervals, and the free ends of all the extension plates 6 are close to each other towards the center of the feed hopper 2 but are not contacted with each other. The elongated plate 6 may increase the splitting effect of the raw material as it falls into the feed hopper 2.

The magnetic separation disc 3 is driven by a motor 12 through a rotating shaft 9, a fan 10 is fixed on the rotating shaft 9, and when the rotating shaft 9 rotates, the fan 10 rotates and blows air in the direction of the motor 12. When the rotating shaft 9 rotates, the rotating shaft 9 can drive the fan 10 to rotate, so that the fan 10 blows air towards the motor 12, and the heat dissipation effect of the motor 12 is accelerated.

All the filter screens 11 are fixedly connected to two opposite side faces of the protective cover 8, and when air in the protective cover 8 flows, the filter screens 11 can filter the air passing through the protective cover 8. In order to prevent a large amount of dust from entering the inside of the protection cover 8 when air flows inside the protection cover 8, filter screens 11 are installed at both sides of the protection cover 8.

A cavity 13 for containing cooling water is arranged in the fixing plate 7, a plurality of through holes 14 for communicating the cavity 13 with the outside are also arranged on the fixing plate 7, and the through holes 14 surround the motor 12. When the outside air temperature is higher, a user injects a certain amount of water into the cavity 13, and when the fan 10 rotates, the water in the cavity 13 is evaporated, so that the heat in the protective cover 8 is taken away, and the purpose of cooling the motor 12 is achieved.

The fixing plate 7 is also provided with a water filling port 15, and the water filling port 15 is communicated with the cavity 13.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
