Abstract
Description
Technical Field
[0001] This utility model relates to the field of flour processing technology, and more specifically, to a screening device for flour processing. Background Technology
[0002] Flour is a powdery substance made from wheat. Based on the protein content, flour can be classified into high-gluten flour, medium-gluten flour, low-gluten flour, and gluten-free flour. Flour (wheat flour) is a staple food in most parts of northern China. There are many varieties of food made from flour, with diverse styles and flavors. After the initial milling, some coarse flour is mixed in, so it generally needs to be sifted using a sieving device.
[0003] However, most existing screening devices can only filter out large particles of impurities in flour, which means they cannot remove fine magnetic impurities and dust, thus affecting the processing quality of flour.
[0004] Furthermore, the feeding speed of the flour cannot be adjusted, which can lead to accumulation when a large amount of flour enters the screening device, thus affecting the normal screening function of the device. Utility Model Content

[0030] Please see Figure 1-5 A screening device for flour processing includes a housing 1, a support 2 fixedly mounted on the inner wall of the housing 1, a first motor 3 mounted on the lower end face of the support 2, the output end of the first motor 3 passing through the support 2 and having a dispersing disc 4, an adsorption box 5 fixedly mounted on the lower end face of the housing 1, an installation block 6 fixedly mounted on the inner wall of the adsorption box 5 and located on one side, an electromagnet rod 7 fixedly mounted on the outer wall of the installation block 6, a storage battery 8 mounted on the outer wall of the housing 1, the storage battery 8 being electrically connected to the electromagnet rod 7, a feeding box 9 fixedly mounted on the upper end face of the housing 1, and an inclined tube 10 fixedly mounted on one side of the feeding box 9.
[0031] In this embodiment, a control box 11 is fixedly installed at the upper end of the inclined tube 10. A second motor 12 is installed on the outer wall of the control box 11. The output end of the second motor 12 passes through the control box 11 and is fixedly installed with a rotating shaft 13. A material distribution blade 14 is installed on the outer wall of the rotating shaft 13. Multiple material distribution blades 14 are arranged in a circular pattern. A storage box 15 is fixedly installed on the upper surface of the control box 11. A sliding groove 16 is opened on the inner wall of the feeding box 9 on both sides. A baffle 17 is slidably installed inside the sliding groove 16. A toggle block is installed on the upper surface of the baffle 17.
[0032] More specifically, the user can power the electromagnet rod 7 with the battery 8 to adsorb small magnetic impurities and dust particles in the flour, making it easier to remove them from the flour and helping to improve the processing quality of the flour. When adding the flour, the user can first add the flour to the storage box 15, and then control the second motor 12 to make the rotating shaft 13 drive the distributing blades 14 to rotate slowly, so that the flour in the middle slowly enters the adsorption box 5 and the screening box 20, thereby preventing the flour from piling up and affecting the normal screening of the flour.
[0033] Please see Figure 1 , Figure 4 and Figure 5As an embodiment for shaking the screening box 20: A conical barrel 18 is fixedly provided on the lower end face of the adsorption box 5, and a discharge pipe 19 is provided at the bottom of the conical barrel 18. A screening box 20 is fixedly provided on the outer wall of the adsorption box 5. Guide rods 21 are fixedly provided on both sides of the inner wall of the screening box 20. The other end of the guide rods 21 is fixedly connected to the discharge pipe 19. A guard plate 22 is slidably provided on the guide rods 21. A screening box 23 is fixedly provided at the bottom of the guard plate 22. A screen hole 24 is opened at the bottom of the screening box 23. A transmission rod 25 is fixedly provided on one side of the screening box 23. A contact block 26 is provided at one end of the transmission rod 25. A third motor 27 is fixedly provided on one side of the screening box 20. A cam 28 is provided at the output end of the third motor 27. The cam 28 contacts the outer wall of the contact block 26. A return spring 29 is provided on both sides of the screening box 23. The other end of the return spring 29 is fixedly connected to the inner wall of the screening box 20.
[0034] Specifically, the user can control the third motor 27 to rotate the cam 28. At this time, the cam 28 will drive the sieving box 23 to swing left and right through the contact block 26 and the transmission rod 25, so that the flour will leak out from the sieve hole 24 and large particles of impurities will remain in the sieving box 23, thereby achieving the screening effect.
[0035] Please refer to Figure 4 As a further embodiment for cleaning the residue inside the screening box 20: the front end of the screening box 23 is provided with a notch, and a cover 30 is hinged to one side of the notch. The cover 30 is fixedly installed to the screening box 23 with screws.
[0036] Specifically, after screening, the user can remove the screws and open the cover 30 to facilitate cleaning the impurities inside the screening box 20.
[0037] In summary, when using the entire equipment: the user can first add flour to the storage tank 15, and then control the second motor 12 to make the rotating shaft 13 drive the distributing blades 14 to rotate slowly, so that the flour in the middle slowly enters the adsorption tank 5 and the screening tank 20, thus preventing the flour from piling up. After the flour enters the adsorption tank 5, the electromagnet rod 7 can be energized by the battery 8 to adsorb small magnetic impurities and dust in the flour, so as to remove them from the flour. To improve the quality of flour processing, the adsorbed flour falls into the sieving box 23 through the conical barrel 18 and the discharge pipe 19. At the same time, the third motor 27 is controlled to rotate the cam 28. The cam 28 then drives the sieving box 23 to sway left and right through the contact block 26 and the transmission rod 25, so that the flour leaks out from the sieve hole 24 and large particles of impurities are left in the sieving box 23, thereby achieving the screening effect. After screening, the user can remove the screws and open the cover 30 to facilitate cleaning the impurities inside the sieving box 20.
