TECHNICAL FIELD
[0001] The utility model relates to the technical field of liquor brewing, particularly relates to a chaff automatic filtering vibrating screen device. BACKGROUND
[0002] Chaff is an important auxiliary material in the solid fermentation process of liquor, mainly relying on its physical support force to play the role of loosening space and circulating air in the liquor production and brewing process. Chaff can increase the oxygen content by increasing the porosity of the fermented grains, improve the growth and reproduction of aerobic bacteria, and promote the extraction of aroma substances and the uniform heating of fermented grains during distillation. Therefore, the coarse chaff with complete structure and full shape has the best loosening effect. However, the chaff purchased usually contains a large amount of dust and impurities, and the damage during processing and transportation will mix small particles of dust or chaff into the chaff, affecting the loosening effect of the chaff and the product quality of the base liquor. The main methods for chaff screening are manual screening, chaff screen screening or fan adsorption filtering screening, which generally have the problems of poor screening effect, low efficiency, complex equipment and inconvenient operation. Therefore, it is urgent to develop a simple and convenient chaff filtering automatic screening device to meet the needs of liquor production and brewing. SUMMARY

[0005] The working principle and beneficial effects of the scheme are as follows: when in use, the chaff is placed on the filter screen, the driver is started, the driver drives the horizontal reciprocating vibration of the box body, the rotation connection of the swing shafts enables the box body to move reciprocatingly, the filter screen is inclined, the chaff gradually moves towards the lower part of the filter screen along with the inclination angle of the filter screen, and the small particles of dust and chaff are screened out below the filter screen. The combination of horizontal reciprocating vibration and the inclination of the filter screen realizes the effective screening of the chaff, improves the work efficiency, effectively separates the complete chaff with large particles from the small particles of dust and chaff, and ensures the quality of the chaff used in the subsequent process.
[0006] Further, the support frame comprises a fixed frame, and a plurality of support rods are fixedly connected to the bottom of the fixed frame.
[0007] Further, the fixed frame is rectangular, and the four support rods are fixedly connected to the four corners of the fixed frame respectively.
[0008] Further, the driver is a reciprocating air cylinder. The air cylinder is used to directly drive the reciprocating movement of the box, and the operation is easier.

The motor is started to drive the rotating disc to rotate, the rotating disc drives the limiting block to eccentrically rotate, the limiting block eccentrically rotates to drive the limiting block to move through the limiting slot, since the limiting block is horizontally limited through the positioning rod, the limiting rod only moves horizontally to drive the positioning rod to move horizontally, thereby driving the box to reciprocatingly move horizontally, since the box is rotationally connected with the support frame through the swing shaft, the box can horizontally reciprocatingly swing under the driving of the positioning rod, thereby performing the screening of the chaff, and compared with the reciprocating effect of the air cylinder, the noise is smaller compared with the vibration motor.
[0010] Further, the fixed block is fixedly connected between the two support rods on the same side, the positioning rod penetrates through the fixed block and is in horizontal sliding connection with the fixed block. The fixed block is arranged to stabilize the movement direction of the positioning rod.
[0011] Further, the bottom of the box is inclined downward. The small-particle dust and broken chaff directly fall from the screen to the bottom of the box.
[0012] Further, the bottom of the box is provided with a waste outlet. The waste outlet is arranged to facilitate the recycling of the small-particle dust and broken chaff. BRIEF DESCRIPTION OF DRAWINGS
