[0028] A sugar powder screening device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.
[0029] Reference Figure 1 A sugar powder screening device according to an embodiment of the utility model comprises a rotating mechanism and a screening mechanism, the rotating mechanism comprises a rotating frame 100 and a power member 110 for driving the rotating frame 100 to rotate, the rotating axis of the rotating frame 100 is arranged obliquely; the screening mechanism comprises a screen 120, the screen 120 is arranged on the rotating frame 100, the screen 120 extends along the rotation direction of the rotating frame 100 to form a screen cavity 130, the screen cavity 130 is used for inputting sugar powder, the screen 120 is provided with at least two screening areas 140, the at least two screening areas 140 are distributed along the rotation axis direction of the rotating frame 100, and the apertures of the at least two screening areas 140 increase from top to bottom along the rotation axis of the rotating frame 100.
[0030] It can be understood that the screen 120 is provided with three screen areas 140 or even four screen areas 140 as required.
[0031] In some embodiments of the present invention, the rotating frame 100 is a cylindrical cage, and the screen 120 extends along the outer circumference of the cylindrical cage to form a screen cavity 130 .
[0032] Therefore, the cylindrical cage has a regular shape, which makes the rotating mechanism rotate smoothly and ensures the effective screening of sugar powder.
[0033] In some embodiments of the present invention, referring to Figure 2 The cylindrical cage has a plurality of connecting rings 150 and connecting strips 160 connecting the plurality of connecting rings 150 , and the plurality of connecting rings 150 are distributed along the axial length direction of the cylindrical cage.
[0034] Therefore, it is ensured that the cylindrical cage has sufficient strength to support the screen 120 and that the powdered sugar effectively collides with the screen 120 .
[0035] In some embodiments of the utility model, the rotating mechanism includes a rotating shaft 170, a support ring 180 is arranged on the inner side of the cylindrical cage, a connecting rib 190 is arranged between the support ring 180 and the cylindrical cage, and the support ring 180 is fixedly mounted on the rotating shaft 170, so that the rotating shaft 170 drives the cylindrical cage to rotate.
[0036] In some embodiments of the present invention, a defective product opening 200 is provided at the bottom end of the cylindrical cage, and a recycling box 210 is provided below the defective product opening 200 . The recycling box 210 is used to receive sugar powder that does not meet the specifications.
[0037] In some embodiments of the present invention, the lengths of at least two screening areas 140 decrease from top to bottom along the rotation axis of the rotating frame 100 .
[0038] It can be understood that the feed port is arranged at the top of the sieve cavity 130, so the powdered sugar falls directly into the high sieve area 140 through the feed port. The high sieve area 140 is longer, which is conducive to fully screening out small-sized powdered sugar. The low sieve area 140 has a small amount of powdered sugar, so it can be fully screened even if the length of the low sieve area 140 is shorter.
[0039] In some embodiments of the present invention, referring to Figure 3 Two vertical plates 220 are arranged in the rotation direction of the rotating frame 100. The two vertical plates 220 are arranged opposite to each other. A screen 120 is accommodated between the two vertical plates 220 to prevent the powdered sugar from flying around and ensure that the sieved powdered sugar falls from under the screen 120.
[0040] In some embodiments of the present invention, a discharge hopper 230 is respectively provided below at least two screening areas 140 , and a receiving box 240 is provided below the discharge hopper 230 . The discharge hopper 230 is used to collect powdered sugar, thereby collecting powdered sugar of different specifications.
[0041] In some embodiments of the utility model, a pulse jet gun 250 is provided in the rotation direction of the rotating frame 100, and the pulse jet gun 250 is located above the screen 120.

[0042] In some embodiments of the present invention, the screening mechanism includes a bracket, which includes two cross beams 260 and support legs 270 disposed at the bottom of the cross beams 260 , and the rotating frame 100 is disposed between the two cross beams 260 .
[0043] Therefore, this embodiment has the following effects:
[0044] 1. The utility model sets a rotating frame 100 and a power member 110 so that the rotation axis of the rotating frame 100 is set at an angle, and the power member 110 is used to drive the rotating frame 100 to rotate, and the screen 120 rotates with the rotating frame 100, and the screen 120 also drives the sugar powder in the screen cavity 130 to move, and the brown sugar powder falls and hits the screen 120, and the brown sugar powder of the required specifications is screened out, thereby reducing the phenomenon of the screen 120 being blocked due to the adhesion of the brown sugar powder, and is also conducive to cooling and breaking up the brown sugar powder.
[0045] 2. The utility model sets at least two sieve areas 140, and the apertures of the two sieve areas 140 increase from top to bottom along the rotation axis of the rotating frame 100. Therefore, when sugar powder is put into the sieve cavity 130 from the top and screened by the two sieve areas 140, small-sized sugar powder is screened out by the high sieve area 140, and large-sized sugar powder slides down along the sieve 120 and falls into the low sieve area 140 for screening. Therefore, the different apertures of different sieve areas 140 are used to screen sugar powders of different sizes, thereby improving the screening efficiency.
