Detailed implementation mode

[0019] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation modes.

[0020] In order to improve the efficiency of the powder grinding operation, as Figures 1-3 shown, a hydrogen storage alloy powder grinding device described in the present utility model includes a mounting base 1, a roller 2 and a grinding cylinder 3. The roller 2 is arranged on the mounting base 1, and the grinding cylinder 3 is arranged inside the roller 2;

[0021] The outer circumference of the roller 2 is provided with a driven gear 21. At the top of one side of the mounting base 1, a reduction motor 22 is installed. The driving end of the reduction motor 22 is installed with a driving gear 24, and the driving gear 24 meshes with the driven gear 21.

[0022] During use, a grinding mechanism for the raw material of the hydrogen storage alloy powder is realized by using the assembly composed of the mounting base 1, the roller 2 and the grinding cylinder 3. The cylinder for storing the grinding material and the roller are designed with a detachable structure, so that the cylinder for storing the grinding material can be directly taken out after the grinding is completed, and the cylinder for the next batch of grinding material to be inserted can be quickly inserted into the roller. Therefore, after each batch of powder grinding, the powder can be quickly discharged and the discharge can be replaced, reducing the interval time of each batch of grinding work, and achieving the effect of improving the efficiency of the powder grinding operation.

[0023] Both ends of the roller 2 are rotatably connected to both ends of the mounting base 1 through bearings 11, and a positioning slot 211 is opened on the inner circumference of one end of the roller 2.

[0024] The grinding cylinder 3 includes a material cylinder 31 with an inserting strip 38 connected to the outer circumference. The material cylinder 31 is inserted into the roller 2, and the inserting strip 38 is inserted into the positioning slot 211. One end of the material cylinder 31 is provided with a feed inlet 32, and an end cover 33 is installed on the feed inlet 32 through a hinge.

[0025] In order to screen and filter the powder, exemplarily, as Figures 1-3 shown, the present utility model further includes that a powder discharge port 34 is opened on one side of the material cylinder 31. A metal filter screen 35 for filtering the powder is welded and connected in the powder discharge port 34. A protective cover 36 is covered on the powder discharge port 34, and buckles 37 are embedded at both ends of the protective cover 36.

[0026] In use, the protective cover 36 on the grinding cylinder 3 after grinding is opened, and the powder discharge port 34 is turned downward, so that the qualified powder after grinding in the grinding cylinder 3 is discharged through the metal filter screen 35, while the unqualified alloy particles can remain in the grinding cylinder 3 and are ground again together with the metal material to be ground added later.

[0027] The present utility model further includes that one end of the material cylinder 31 is connected to the end of the roller 2 through the first metal buckle 4, and the end cover 33 is connected to the material cylinder 31 through the second metal buckle 5.

[0028] When the present utility model is in use, the hydrogen storage alloy raw material to be ground and the abrasive are sent into the grinding cylinder 3 through the feed port 32, the end cover 33 is set on the grinding cylinder 3, and the end cover 33 is buckled to the grinding cylinder 3 through the second metal buckle 5. Then the grinding cylinder 3 is inserted into the roller 2. After insertion, through the limitation in the inner cavity of the roller 2, the protective cover 36 can stably cover and protect the powder discharge port 34. Through the insertion and positioning of the positioning slot 211 and the insertion bar 38, the grinding cylinder 3 is fixed in the roller 2. Then the grinding cylinder 3 and the roller 2 are buckled and fixed through the first metal buckle 4. The reduction motor 22 drives the driving gear 24 to drive the driven gear 21 to rotate, so that the roller 2 drives the grinding cylinder 3 to rotate, and thus the hydrogen storage alloy raw material and the abrasive in the grinding cylinder 3 are frictionally ground. During grinding, the staff can prepare the next set of grinding cylinders 3 that need grinding work in advance. After grinding, the staff unbuckles the first metal buckle 4, pulls out the grinding cylinder 3 from the roller 3, and inserts the previously prepared next set of grinding cylinders 3 into the roller 3. After being buckled by the first metal buckle 4, the next set of grinding work is immediately carried out. In this way, the cycle alternates, greatly reducing the interval time of loading and unloading.

[0029] The protective cover 36 on the grinding cylinder 3 after grinding is opened, and the powder discharge port 34 is turned downward, so that the qualified powder after grinding in the grinding cylinder 3 is discharged through the metal filter screen 35, while the unqualified alloy particles can remain in the grinding cylinder 3 and are ground again together with the metal material to be ground added later. The present application can screen the powder after grinding while meeting the improvement of the grinding efficiency of the hydrogen storage alloy powder, and is flexible and convenient to use.
