[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Embodiment 1:

[0027] Reference Figure 1-4 The grading and screening device for powdered raw materials includes a bracket 1, and also includes: a cylinder 2, which is rotatably connected to the bracket 1; a partition 201, which is fixedly connected to the cylinder 2, and the partition 201 is provided with large sieve holes; a partition 202, which is fixedly connected to the cylinder 2, and the partition 202 is provided with small sieve holes. As shown in the figure, the partition 201 is close to the center of the cylinder 2, and the partitions 1 201 and 202 divide the cylinder 2 into three spaces. A driving motor 101 is fixedly connected to the bracket 1, and the output end of the driving motor 101 is fixedly connected to the cylinder 2, and a rotating door is rotatably connected to the cylinder 2.

[0028] When the device is in use, first open the rotating door, pour the raw materials to be screened into the partition 201, then close the rotating door and start the drive motor 101. The cylinder 2 can be made of a transparent material to facilitate observation of whether the screening is completed. During this process, as the cylinder 2 continues to rotate, the raw materials in the partition 201 will continue to roll, and then the smaller raw materials will fall through the large sieve holes and come to the partition 202 for initial screening. Subsequently, as the cylinder 2 continues to rotate, the raw materials on the partition 202 will fall onto the outer wall of the cylinder 2, and finally the raw materials will be divided into three parts. Subsequently, the drive motor 101 can be closed, the rotating door can be opened, and the screened raw materials can be taken out.

[0029] Embodiment 2:

[0030] Reference Figure 1-4, a grading and screening device for powdered raw materials is basically the same as that in Example 1, and further: a plurality of groups of protrusions 3 are arranged on the cylinder 2, a sliding rod 103 is connected to the bracket 1, a groove is arranged in the sliding rod 103, a spring member 104 is connected in the groove, a knocking block 105 is connected to the spring member 104, the knocking block 105 is used to knock the protrusion 3, a sliding groove is arranged on the sliding rod 103, a rotating screw rod 102 is rotatably connected in the sliding groove, the sliding rod 103 is threadedly connected to the rotating screw rod 102, and the sliding rod 103 is slidably connected in the sliding groove, and a rotating handle is fixedly connected to the rotating screw rod 102.

[0031] As shown in the figure, the protrusions 3 are divided into three columns, the first column has the least number and there are longer intervals between them, the second column in the middle has the middle number, and the third column has the largest number and the smallest intervals. When in use, the sliding rod 103 can be moved by rotating the screw rod 102, and then the knocking block 105 can be moved to the top of any column. At this time, when the cylinder 2 rotates, the knocking block 105 will continue to contact the protrusion 3, thereby generating vibration. The vibration at this time will cause the raw materials in the cylinder 2 to vibrate slightly, thereby promoting the screening effect. The more protrusions 3 there are, the better the screening effect. It can also be moved to a position without protrusions 3 without knocking and vibration.

[0032] Embodiment 3:

[0033] Reference Figure 1-4 The grading and screening device for powdered raw materials is basically the same as that in Example 1, and furthermore: a plurality of support frames 203 are fixedly connected to the cylinder 2, and the support frames 203 are used to support the partition 1 201 and the partition 2 202.

[0034] By providing the support frame 203, the strength can be effectively improved to facilitate long-term use.

[0035] The utility model can effectively screen the raw materials through the arrangement of the partition plate 1 201 and the partition plate 202. At the same time, the arrangement of the knocking block 105 and the protrusion 3 can generate vibration, thereby improving the screening effect and facilitating use.

[0036] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
