Novel wheat screening device for flour processing

Abstract

The invention relates to the technical field of wheat screening machines, and particularly discloses a novel wheat screening device for flour processing. The novel wheat screening device comprises a bottom plate, a screening barrel and a feeding hopper, wherein the lower surface of the screening barrel is connected with a plurality of supporting legs; the supporting legs are fixedly connected to the upper surface of the bottom plate; a plurality of feeding openings are formed in the circle center of the upper surface of the screening barrel in an annular array mode; the feeding hopper is arranged at the circle center of the upper surface of the screening barrel; a cleaning opening is formed in the top wall, located beside the feeding hopper, of the screening barrel; a cover plate is rotationally arranged on the cleaning opening; a bearing is arranged at the circle center of the top wall of the screening barrel; a rotating shaft is welded to the bearing; and the lower end of the rotating shaft is connected with a centrifugal screening disc. The novel wheat screening device can screen large gravels, small gravels and wizened and empty wheat in wheat at the same time, and is compact in structure and small in occupied area.

Description

technical field [0001] The invention relates to the technical field of wheat screening machines, and specifically discloses a novel wheat screening device for flour processing. Background technique [0002] When people process wheat into flour, they first need to filter and screen the wheat, the purpose of which is to screen out the empty husk wheat and gravel in the wheat. At present, people need to go through multi-process screening when screening wheat. In the first screening step, the shriveled and empty wheat is removed by winnowing machine, and then the multi-stage screening machine is used to pass through the first screen with different apertures and the The second screen removes large and small gravels respectively. The screening steps are complicated, and the entire screening system occupies a large area and has high equipment components. [0003] For example, the utility model whose patent number is CN208261261U discloses a wheat screening production line, which i...

At present, people need to go through multi-process screening when screening wheat. In the first screening step, the shriveled and empty wheat is removed by winnowing machine, and then the multi-stage screening machine is used to pass through the first screen with different apertures and the The second screen removes large and small gravels respectively. The screening steps are complicated, and the entire screening system occupies a large area and has high equipment components.

[0003] For example, the utility model whose patent number is CN208261261U discloses a wheat screening production line, which includes a crushing device, a first screening device, a second screening device and a milling device, wherein the crushing device passes through the first conveyor belt mechanism and the first screening device connection, the first screening device includes a bracket and a sieve body mounted on the bracket by a spring, an upper sieve and a lower sieve are respectively arranged on the sieve body along the up and down direction, and the lower end of the lower sieve is provided with a wheat grain outlet The lower part of the lower screen is provided with a sundries bin, the sundries bin is inclined and the lower end of the sundries bin is provided with a gravel outlet; after the first screening device, a second screening device is provided through a second conveyor belt mechanism, The second screening device includes a chassis, a vibrating motor, a screen, and a feeding hopper. The vibrating motor electric control box is set on the chassis, the feeding hopper is set on the top of the chassis, the bottom of the feeding hopper is set with a distributor, and the lower part of the distributor is provided with three feeding troughs , the distributor includes the first compartment, the second compartment and the third compartment that are evenly divided. The three compartments are all funnel-shaped with a large upper part and a small lower part. The lower parts of the three compartments are respectively provided with a first outlet, a The second exit and the third exit; although the wheat screening production line can sequentially realize winnowing, first vibration screening, and second vibration screening of wheat during the wheat screening process, there are many screening steps in the whole screening process, and the whole set of screening The equipment occupies a large area and the equipment composition is higher
