Description

Technical Field

[0001] The utility model relates to the technical field of pulverizing devices, in particular to a desulfurized gypsum pulverizing device. Background Art

[0002] The gypsum powder produced during the desulfurization process is often mixed with lumps of different sizes, which will seriously affect the quality and use of the gypsum powder. Especially when large and small lumps exist at the same time, there will be problems with using traditional filtering and crushing technologies to handle them. Specifically, the gaps or gaps in the filtering and crushing system may not be able to effectively capture and crush smaller lumps when dealing with large lumps, causing these small lumps to slip through the screen without being fully processed along with the gypsum powder, ultimately affecting the smooth progress of downstream processes and the quality of finished products.

[0003] In terms of adjusting the particle size of the output material, since traditional devices often use fixed-size gap grinding, the ability to adjust the particle size is limited. Without a precise control mechanism, even small agglomerates that have been broken may not achieve the ideal grinding effect when passing through the grinding gap, resulting in uneven particle size of the output material.

[0004] In view of this, traditional gypsum powder filtering and crushing devices have the problem of being unable to efficiently separate and crush different sized agglomerates in the powder, and unable to flexibly adjust the gap to adapt to different grinding requirements. Utility Model Content

[0038] Working principle:

[0039] During use, gypsum powder is put into the first frame 2 from the feed port 4, and the powder falls to the top of the screen 18. The powder that has agglomerated into agglomerates is filtered from the screen 18. As the rotating rod 12 rotates, the agglomerated powder is carried by the crushing net 19 to rub against the top of the screen 18. The agglomerated powder is decomposed by friction and passes through the screen 18.

[0040] The powder falls downward from the first frame 2 to between the first grinding sheet 15 and the second grinding sheet 16, and the second motor 5 is used to drive the screw to rotate, so that the crushing frame 8 moves in the slide 17, thereby changing the distance between the first grinding sheet 15 and the second grinding sheet 16, and the first rotating rod 12 rotates to squeeze the first grinding sheet 15 and the second grinding sheet 16 to squeeze the powder, and the particle size of the discharged material is consistent with the distance between the first grinding sheet 15 and the second grinding sheet 16; then the ground powder is discharged from the discharge port 9;

Among them, the first motor 3 drives the rotating rod 12 with the grinding disc to rotate, which can crush the agglomerated gypsum powder at the crushing net 19 and then filter it through the screen 18. The second motor 5 adjusts the vertical position of the crushing frame 8 through the screw rod to control the grinding gap, thereby realizing precise control of the particle size. The device is also designed with a discharge port 9 to facilitate the discharge of the crushed material. The entire equipment has a compact structure, convenient operation, simple maintenance, and can ensure the processing quality of gypsum powder;
