Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flour production, in particular to a bran filtering device for flour production. Background Art
[0002] Flour is a powder made from wheat. According to the protein content in the flour, it can be divided into high-gluten flour, medium-gluten flour, low-gluten flour and gluten-free flour. When producing flour, the wheat needs to be kneaded and peeled. During the kneading process, the wheat epidermis is separated from the wheat grains, and the wheat grains become crushed, and the bran is in the form of flakes. The bran needs to be removed. In the prior art, a screening net is generally used to remove the bran from the flour.
[0003] The publication number of the existing public technology is: CN214812433U. A bran filtering device for flour production comprises a bottom plate, a support rod is fixed on the top of the bottom plate, and a support collar is fixedly installed on the top of the support rod, a rotatable screening cylinder is sleeved on the inner side of the support collar, a driven gear ring is sleeved on the outer side of the lower part of the screening cylinder, a dust cover is fixedly installed on the top of the bottom plate, a motor is fixedly installed inside the dust cover, the output shaft of the motor extends through the outer side of the dust cover and is concentrically connected with a driving gear, the driving gear and the driven gear ring are connected by a synchronous belt, and a heater is provided on the upper side of the screening cylinder to fit therewith. The utility model can better reduce the influence of agglomeration during the screening of flour and improve the effect of bran screening; it can improve the screening efficiency of flour during the screening process, reduce the occurrence of flour agglomeration caused by environmental factors such as moisture, and further improve the effect of separating flour bran.
[0004] However, the above patent still has certain disadvantages when used: when filtering the bran in the flour, it is processed through the screening drum, and the inclination angle of the screening drum is fixed, which causes the fallen flour and bran to accumulate in large quantities at the bottom of the screening drum due to gravity, thereby causing the flour in this area to be unable to be fully processed, and it passively contacts the agglomerated flour through the crushing rod, and when the contact speed of the flour with it is slow, it cannot be smoothly crushed, affecting the subsequent filtering effect, and the flour and bran are easily attached to the inner wall of the screening drum to cause the clogging of the holes, which will directly affect the subsequent discharge of flour, resulting in a significant reduction in the filtering effect of the bran, and the use effect is not very good.
[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0032] In one embodiment, a collecting box 17 is installed at the bottom end of the supporting frame 2, and the collecting box 17 is provided to collect the filtered flour.
[0033] In one embodiment, adjustment grooves 15 are symmetrically provided on the two side surfaces of the bottom of the carrier frame 2, and a connecting shaft 14 is provided inside the adjustment groove 15. The connecting shaft 14 is rotatably connected to the top of a hydraulic rod 16. The hydraulic rod 16 is provided to adjust the inclination direction of the screening drum 4, thereby preventing a large amount of flour and bran from accumulating in a certain position, which would result in failure to smoothly perform filtering and screening.
[0034] In one embodiment, a plurality of groups of filter screens 8 are installed around the surface of the screening cylinder 4. The filter screens 8 are provided to filter the flour and bran.
[0035] In one embodiment, support rings 6 are symmetrically welded on both sides of the bottom surface of the support frame 2 , and the support rings 6 are located on the outer peripheral surface of the screening drum 4 . The support rings 6 are provided to support the screening drum 4 .

[0039] Working principle: In actual use, personnel can add flour to be filtered through the feed pipe 7. At this time, the falling flour will fall into the inside of the screening drum 4. At this time, the relative reciprocating lifting and lowering operation of the hydraulic rods 16 on both sides can make the inclination position of the screening drum 4 change, thereby preventing the flour from being accumulated in a certain position for a long time and affecting the overall filtering effect. Then, when the angle of the screening drum 4 changes, the operation of the first motor 3 and the second motor 13 can drive the driving shaft 12 to rotate in the opposite direction to the rotation direction of the screening drum 4, so that the flour inside can be fully filtered. It is in contact with the driving shaft 12, so that the beating rod 11 and the auxiliary rod 10 on the surface of the driving shaft 12 can better beat the flour, thereby preventing the flour from clumping, and when the driving shaft 12 rotates, the scraper 9 on the surface can continuously scrape the inside of the screening drum 4, so that there is no accumulation of flour and bran on the inner wall, so that the flour can smoothly fall from the filter net 8 on the surface of the screening drum 4, while the bran remains inside it, realizing the filtering operation of the bran and improving the overall processing effect. The device as a whole has the advantages of filtering and preventing accumulation, good filtering effect, and anti-clogging coverage.
