Technical Field

[0001] The utility model relates to the technical field of Raney nickel powder preparation, in particular to a Raney nickel powder preparation device. Background Art

[0002] Raney nickel is a solid heterogeneous catalyst composed of fine grains of nickel-aluminum alloy with a porous structure. It is usually used as a hydrogenation catalyst for organic compounds and can be used for hydrogenation reduction reactions of compounds containing unsaturated bonds such as aldehydes and ketones. Raney nickel is extremely flammable when exposed to air and is somewhat dangerous.

[0003] Most of the existing devices for preparing Raney nickel powder use a crushing knife to crush the Raney nickel, and then use a filtering device to collect the Raney nickel powder.

[0004] Although Raney nickel powder can be prepared by this method, using only a crushing knife to crush the Raney nickel powder will result in uneven crushed Raney nickel particles, which will affect the quality of the powder prepared and collected subsequently.

[0005] Therefore, we made improvements to this and proposed a device for preparing Raney nickel powder. Utility Model Content

DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example: Figures 1 to 4 As shown, the utility model is a device for preparing Raney nickel powder, comprising a preparation barrel 1 and a barrel cover 2, wherein a feed port 4 is fixedly connected to the top of the preparation barrel 1, a discharge port 10 is fixedly connected to the bottom of the preparation barrel 1, a first filter plate 6 is arranged inside the preparation barrel 1, a second filter plate 7 is arranged below the first filter plate 6, a crushing assembly for crushing Raney nickel is arranged inside the preparation barrel 1, the crushing assembly comprises a crushing rod 8 rotatably arranged inside the preparation barrel 1, crushing knives 82 are fixedly connected to both sides of the crushing rod 8, a cavity 81 is opened inside the crushing rod 8, a ball 83 is rollingly arranged in the cavity 81, and the ball 83 is in rolling contact with the surface of the first filter plate 6.

[0022] The Raney nickel in the preparation barrel 1 is preliminarily crushed by using a crushing knife 82 fixedly connected to a crushing rod 8 in a crushing assembly arranged inside the preparation barrel 1, and then the preliminarily crushed Raney nickel particles on the first filter plate 6 are secondarily ground by using rolling friction between a ball 83 rollingly arranged in the internal cavity 81 of the crushing rod 8 and the first filter plate 6, thereby further improving the quality of the Raney nickel powder.

[0023] A motor 3 is fixedly connected to the barrel cover 2, and the output shaft of the motor 3 is vertically downward and fixedly connected to a rotating rod 5 through a coupling. The end of the rotating rod 5 away from the motor 3 is rotatably connected to the second filter plate 7 through a bearing 11. The rotating rod 5 and the first filter plate 6 are rotatably connected, and a crushing rod 8 is fixedly connected to the rotating rod 5. Two groups of crushing rods 8 are arranged on the outer peripheral wall of the rotating rod 5, and the two groups of crushing rods 8 are symmetrical to each other.

[0024] By utilizing the motor 3 fixedly connected to the barrel cover 2 to drive the rotating rod 5 to rotate, and utilizing the fixed connection between the rotating rod 5 and the crushing rod 8, it is more convenient to utilize the motor 3 to drive the crushing rod 8 to rotate in a circle inside the preparation barrel 1, which is more convenient for crushing the Raney nickel.

[0025] The bottom of the rotating rod 5 is fixedly connected with a grinding rod 9 . Two groups of grinding rods 9 are arranged at the bottom of the rotating rod 5 in a symmetrical structure. The bottom of the grinding rod 9 is provided with grinding balls 91 . The grinding balls 91 are in sliding contact with the surface of the second filter plate 7 .

[0026] By utilizing the grinding rod 9 fixedly connected to the bottom of the rotating rod 5 , the Raney nickel powder on the first filter plate 6 can be subjected to secondary grinding, thereby further improving the dispersion and quality of the Raney nickel powder.

[0027] The ends of the crushing rods 8 and the grinding rods 9 on both sides close to the inner wall of the preparation barrel 1 are fixedly connected with brush heads 12, and the brush heads 12 are in contact with the inner wall of the preparation barrel 1. By using the brush heads 12 fixedly connected to the ends of the crushing rods 8 and the grinding rods 9 close to the inner wall of the preparation barrel 1, it is easier to brush off the powder attached to the inner wall of the preparation barrel 1, which is more convenient to use.

[0028] The mesh number of the first filter plate 6 is smaller than the mesh number of the second filter plate 7. By arranging the second filter plate 7 having a mesh number larger than that of the first filter plate 6 below the first filter plate 6, the first filter plate 6 and the second filter plate 7 can be used to perform double filtration on the Raney nickel powder, which is more convenient to use.

[0029] The top of the discharge port 10 in the preparation barrel 1 is provided with a funnel-shaped structure. By passing the powder prepared by crushing in the preparation barrel 1 through the funnel-shaped structure, it is more convenient to discharge the Raney nickel powder through the discharge port, and it is more convenient to collect the Raney nickel powder.

[0030] During operation, when it is necessary to prepare Raney nickel powder, the Raney nickel particles to be prepared are put into the preparation barrel 1 through the feed port 4, and then the motor 3 is started, and the motor 3 is used to drive the rotating rod 5 to rotate. The crushing rod 8 and the grinding rod 9 fixedly connected to the rotating rod 5 rotate with the rotation of the rotating rod 5, and the crushing knife 82 fixedly connected to the rotating crushing rod 8 is used to crush the Raney nickel particles on the first filter plate 6. At the same time, the balls 83 rolling in the cavity 81 opened on the crushing rod 8 can be used to perform preliminary grinding on the Raney nickel particles on the first filter plate 6. When the Raney nickel powder crushed and ground by the crushing knife 82 and the balls 83 passes through the first filter plate 6 and falls onto the second filter plate 7 below it, the grinding balls 91 fixedly set at the bottom of the grinding rod 9 are used to perform secondary grinding on the Raney nickel powder on the second filter plate 7, which can further improve the grinding quality of the Raney nickel powder. After the preparation of the Raney nickel powder is completed, it can be discharged through the discharge port 10.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
