[0002] The main raw material of flour is grain. In most areas, especially in the north, wheat is the main grain. The quality of wheat directly affects the quality of flour. The wheat after tempering will be sent to the crusher for crushing and grinding the wheat into powder. The crushing equipment can be a traditional stone mill or a modern mechanical mill. During the grinding process, the wheat is broken into small flakes and the starch is extracted from the wheat grains. The mill will repeat this process until the wheat is completely crushed and the required flour fineness is obtained; however, the flour obtained after grinding needs to be sieved through a sieve to remove coarse particles and impurities to obtain a finer flour. The screening equipment is usually composed of multiple sieves of different specifications; in general, the flour production process is a complex process with multiple links and multiple equipment. Each link has its specific role and requirements. Through reasonable process and equipment selection, high-quality and good-tasting flour can be produced to meet the needs of different consumers;

[0003] However, during the use of common impurity screening devices for flour production, impurities in the flour cannot be screened out completely at one time, and the screened impurities are likely to absorb flour, resulting in serious flour waste.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment 1

[0029] This embodiment is an impurity screening device for flour production.

[0030] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, the front side of the storage box 1 is rotatably connected to the box door 2, the scattering motor 3 is fixedly installed on the lower side of the storage box 1, the output shaft of the scattering motor 3 is fixedly connected to the connecting shaft 4, and a scattering rod 5 is provided on the outside of the connecting shaft 4. The scattering rod 5 is symmetrical about the vertical center axis of the connecting shaft 4, and a screening box 6 is provided on the upper side of the storage box 1. A vibration motor 7 is provided on the front side of the screening box 6, and an eccentric wheel 8 is provided on the outside of the output shaft of the vibration motor 7. The screen 9 is rotatably connected to the screening box 6, and the outer side of the screen 9 is tightly fitted with the inner side of the screening box 6. A feed hopper 10 is provided on the upper side of the screening box 6.

[0031] like Figure 1 、 Figure 2 and Figure 4 As shown, a material pump 11 is provided on the upper side of the storage box 1, a return pipe 12 is provided at the lower left side of the material pump 11, the left side of the return pipe 12 is fixedly connected to the screening box 6, a conveying pipe 13 is provided at the upper left side of the material pump 11, and the conveying pipe 13 is located above the feed hopper 10, a mounting frame 14 is provided on the left side of the storage box 1, a conveyor belt 15 is provided on the upper side of the mounting frame 14, a drying rack 16 is provided on the upper side of the conveyor belt 15, and a heating wire 17 is provided inside the drying rack 16, and the heating wire 17 is distributed in an array.

[0032] It should be noted that after the flour is ground, the bran and flour still contain moisture. When screening, the flour easily blocks the sieve holes inside the screen 9, resulting in low screening efficiency and prolonged screening time. Therefore, it is necessary to heat and dry the area to remove the moisture inside it to facilitate screening. After the flour is evenly spread on the upper side of the storage box 1, the heating wire 17 on the lower side of the drying rack 16 is started. The heating wire 17 will emit heat, and the drying rack 16 will also reduce heat overflow, which is convenient for drying and removing moisture from the flour. The conveyor belt 15 is started to transport the flour to the upper side of the feed hopper 10, and then the flour falls under the action of gravity and falls into the inside of the feed hopper 10, which is convenient for screening. Specific embodiment 2

[0033] This embodiment is intended to solve the problem of poor screening effect.

[0034] like Figure 1 、 Figure 2 and Figure 3As shown, when the flour enters the screening box 6 from the feed hopper 10, the vibration motor 7 and the material pump 11 are started, and the flour falling on the upper side of the screen 9 will be screened by the screen 9, and the fine flour will fall into the inside of the storage box 1, while the flour adsorbed on the impurities will accumulate on the upper side of the screen 9. The rotation of the vibration motor 7 will make the eccentric wheel 8 periodically contact the screen 9, so that the left side of the screen 9 rises. When the eccentric wheel 8 is disconnected from the screen 9, the screen 9 will fall under the action of gravity, thereby vibrating the flour on the upper side of the screen 9, allowing the impurities to slide to the right, and then enter the material pump 11 from the reflux pipe 12, and then be discharged from the conveying pipe 13 to the feed hopper 10 for re-screening to reduce the waste of flour.

[0035] It should be noted that when it is found that the impurities discharged from the conveying pipe 13 contain almost no flour, the impurities are collected with a nearby container to prevent the impurities from entering the interior of the screening box 6, which would slow down the screening efficiency. Specific embodiment three

[0036] This embodiment is to solve the problem of flour accumulation.

[0037] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, when flour slides down from the screen 9, it will accumulate in the middle of the storage box 1. The slowly accumulated flour will cause the flour to be only in the middle of the storage box 1, forming a triangular cone shape, which is inconvenient for storing flour. Start the beating motor 3, and the beating motor 3 will rotate with the beating rod 5 through the connecting shaft 4. The rotating beating rod 5 will evacuate the flour and spread it all over the inside of the storage box 1. After the screening is completed, open the box door 2 to take the flour out from the inside of the storage box 1, which is convenient for operation.
