[0029] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be described in further detail below with reference to the drawings.

[0030] Please refer to Figures 1 to 4 The utility model discloses a granulating and screening device for FeSiGr alloy powder insulation preparation, which comprises:

[0031] The granulating frame 12 is fixed to the center of the upper surface of the screening device 11, and the two granulating rollers 13 are rotatably installed inside the granulating frame 12. The upper surface of the granulating frame 12 is fixed with a feeding frame 14, and the feeding frame 14, the granulating frame 12 and the screening device 11 are mutually penetrated.

[0032] The screening device 11 screens the alloy particles. The granulating frame 12 can collect the alloy powder from the feeding frame 14 and realize the molding process of the alloy powder under the action of the granulating rollers 13. The two granulating rollers 13 rotate oppositely and generate extrusion force on the alloy powder during the rotation. The alloy powder is extruded into the required particle shape on the surface of the granulating rollers 13.

[0033] The collecting assembly comprises a fixed block 21, a mounting groove 22, a first spring 23 and a connecting brush 24. The fixed block 21 is fixed to the two sides of the granulating frame 12. The mounting groove 22 is formed on one side of the fixed block 21. The first spring 23 is fixed inside the mounting groove 22. The connecting brush 24 is fixed to one end of the first spring 23 and is in contact with the outer surface of the granulating roller 13.

[0034] During the rotation of the granulating roller 13, the connecting brush 24 tightly abuts against the outer surface of the granulating roller 13 under the elastic force of the first spring 23. The connecting brush 24 brushes off the residual alloy powder through the friction with the surface of the granulating roller 13.

[0035] The two sides of the granulating frame 12 are fixed with a collecting frame 25. One side of the collecting frame 25 is fixed with a connecting shaft 26.

[0036] The outer surface of the connecting shaft 26 penetrates through a discharging plate 27. The outer surface of the discharging plate 27 is provided with a rotating groove 271 which penetrates through the connecting shaft 26. The discharging plate 27 is located below the connecting brush 24, and one end of the discharging plate 27 extends into the interior of the granulating frame 12.

[0037] The main function of the collecting frame 25 is to collect the alloy particles falling from the granulating roller 13. The main function of the connecting shaft 26 is to connect and support the discharging plate 27, fix the discharging plate 27 on the collecting frame 25 and make the discharging plate 27 keep a stable position in the collecting frame 25. The main function of the discharging plate 27 is to guide the alloy particles in the collecting frame 25 into the granulating frame 12.

[0038] Working principle:

[0039] When the alloy powder is put into the inside of the feeding frame 14, the alloy powder is pressed into granules by the granulating roller 13, and when the granulating roller 13 rotates, the first spring 23 drives the connecting brush 24 to abut against the granulating roller 13 under the elastic force of the spring, the alloy powder remaining on the outer surface of the granulating roller 13 is brushed off, and the brushed-off alloy powder is guided by the discharging plate 27 and slides into the collecting frame 25, the residual powder is brushed off in time by the connecting brush 24, which can ensure that the amount of the alloy powder participating in the granulation is relatively constant each time, and the size of the produced alloy granules is more uniform.

[0040] This step helps to improve the quality stability of the product, reduce equipment wear and tear, and prolong the equipment maintenance cycle.

[0041] Please refer to Figures 1 to 4 The embodiment is based on the above-mentioned embodiment and further includes:

[0042] The mounting assembly includes a fixed frame 31, a second spring 32, a clamping column 33 and a limiting frame 34, the fixed frame 31 is fixed on both sides of the collecting frame 25, the second spring 32 is fixed inside the fixed frame 31, the clamping column 33 is fixed at one end of the second spring 32, and the limiting frame 34 is fixed on both sides of the granulating frame 12.

[0044] The fixed frame 31 serves as a support structure of the entire mounting assembly and provides a stable support basis for the collecting frame 25, the second spring 32 mainly provides elastic force, the main function of the clamping column 33 is to lock the collecting frame 25 in the limiting frame 34 to prevent the collecting frame 25 from accidentally falling off during the operation of the equipment, and the limiting frame 34 provides guidance and positioning for the installation and movement of the collecting frame 25.

[0045] Working principle:

[0046] When the alloy powder in the collecting frame 25 is collected to the full, the second spring 32 can be compressed in the fixed frame 31 directly through the unlocking groove 311, and the clamping column 33 is driven to exit from the fixed hole 35 synchronously when the second spring 32 is compressed, at this time, the collecting frame 25 can be taken out from the limiting frame 34, and vice versa, the collecting frame 25 can be installed into the limiting frame 34, and the collecting frame 25 can be quickly taken out and replaced with a new one through the structure such as the unlocking groove 311.

[0047] This step does not need to be shut down for a long time to carry out complex disassembly and installation operation, which helps to maintain the continuity of the production process and improve the overall production efficiency.
