Description

Technical Field

[0001] The utility model belongs to the technical field of screening devices, and in particular relates to a flour sorting sieve. Background Art

[0002] Flour is a powder made from wheat. It is the staple food in most parts of northern China. Foods made from flour are of various types, with various styles and flavors. Flour is divided into special flour, general flour and nutritionally fortified flour according to its performance and use; it is divided into special first-grade flour, special second-grade flour, standard flour and ordinary flour according to its precision; it is divided into high-gluten flour, medium-gluten flour and low-gluten flour according to its gluten strength. In the process of producing and processing flour, flour needs to be screened.

[0003] Since flour will become damp and agglomerated after being stored for a long time, the agglomerated flour will clog the sieve holes of the sieve when the sieve is sifting the flour. At this time, the staff needs to use a cleaning tool to clean the sieve, but some of the sieve holes will still be clogged or some flour will accumulate at the junction of the screening shell and the sieve. In the long run, the screening effect of the flour is reduced. Therefore, a flour sorting sieve that does not require frequent cleaning of the sieve is proposed. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. It should be pointed out that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative sizes and proportions of the parts shown in the figures are exaggerated or reduced in size, and any size is only exemplary and not restrictive.

[0027] Example:

[0028] See also Figure 1 - Figure 4 As shown, a flour sorting sieve comprises:

[0029] A screening tank 1, wherein a feed hopper 11 and a bifurcated discharge pipe 12 are respectively fixedly mounted at the upper and lower ends of the screening tank 1;

[0030] The sieve plate 2 is rotatably mounted inside the screening tank 1;

[0031] A reversing plate 3, which is rotatably mounted inside the bifurcated discharge pipe 12 and is used to replace the flour outlet;

[0032] The reversing mechanism 4 is used to control the flipping of the sieve plate 2 and the reversing plate 3;

[0033] A vibration motor 5, the vibration motor 5 is fixedly mounted on the outer side of the screening tank 1;

[0034] The shock absorbing support 6 is fixedly connected to the outer surface of the screening tank 1 .

[0035] As can be seen from the above, since the sieve plate 2 is rotatably installed inside the screening tank 1, when the upper surface of the sieve plate 2 is accumulated with agglomerated flour and its sieve holes are partially blocked by flour, flipping the sieve plate 2 can make the agglomerated flour fall off, and under the action of the vibration motor 5, the flour on one side of the blocked sieve holes will also fall off. Due to the setting of the reversing plate 3, when the reversing plate 3 is close to one end of the forked discharge pipe 12 to block one of the outlets, the fallen flour can only slide from one side thereof to the other outlet of the forked discharge pipe 12. Therefore, the sieve plate 2 and the reversing plate 3 are both controlled by the reversing mechanism 4 and can work synchronously, so that the flour that has passed the screening and the flour that has not passed the screening can be discharged from different outlets of the forked discharge pipe 12.

[0036] Specifically, by Figure 4 It can be seen that a discharge port 13 communicating with the inside of the bifurcated discharge pipe 12 is provided at the bottom of the screening tank 1 , and the width of the discharge port 13 is smaller than the width of the upper end of the bifurcated discharge pipe 12 .

[0037] As can be seen from the above, since the width of the discharge port 13 is smaller than the width of the upper end of the forked discharge pipe 12, when the reversing plate 3 is attached to the inner wall of one side of the forked discharge pipe 12, the flour cannot pass through the gap between the reversing plate 3 and the inner wall of one side of the forked discharge pipe 12.

[0038] Specifically, by Figure 1 and Figure 3 It can be seen that the reversing mechanism 4 includes a first rotating shaft 41, a second rotating shaft 42, a first transmission wheel 43 and a second transmission wheel 44. The first rotating shaft 41 is fixedly connected to the middle part of the screen plate 2, and its two ends are respectively rotatably connected to the two side walls of the screening tank 1. The second rotating shaft 42 is fixedly connected to the lower end of the reversing plate 3, and its two ends are respectively rotatably connected to the two side walls of the forked discharge pipe 12. The first transmission wheel 43 is fixedly installed on one end of the first rotating shaft 41 extending to the outside of the screening tank 1, and the second transmission wheel 44 is fixedly installed on one end of the second rotating shaft 42 extending to the outside of the forked discharge pipe 12. The first transmission wheel 43 and the second transmission wheel 44 are connected by a transmission belt 45.

[0039] As can be seen from the above, under the action of the first transmission wheel 43, the second transmission wheel 44 and the transmission belt 45, the first rotating shaft 41 and the second rotating shaft 42 are driven. By setting the radius ratio of the first transmission wheel 43 and the second transmission wheel 44, the reversing plate 3 can rotate ninety degrees when the screen plate 2 flips one hundred and eighty degrees.

[0040] Specifically, by Figure 2 and Figure 3 It can be known that the reversing mechanism 4 further includes a driving motor 46 , which is fixedly mounted on the outer side of the bifurcated discharge pipe 12 , and a driving end thereof is fixedly connected to the second rotating shaft 42 .

[0041] It can be seen from the above that the first rotating shaft 41 and the second rotating shaft 42 can be driven by the arrangement of the driving motor 46 .

[0042] Specifically, by Figure 2 It can be seen that the shock-absorbing support 6 includes a base plate 61, a spring shock absorber 62 and a support rod 63. The spring shock absorber 62 is fixed on the upper surface of the base plate 61 in a rectangular array, and the two ends of the support rod 63 are fixedly connected to the spring shock absorber 62 and the screening tank 1 respectively.

[0043] As can be seen from the above, by providing the spring damper 62 , the vibration generated by the screening tank 1 can be buffered and reduced.
