Peony seed impurity removal vibrating screen

Abstract

The invention provides an impurity removing vibrating screen for peony seeds, which comprises a rack, a driving motor, a screen body, a screen net and a vibrator. The screen net comprises an upper screen net body and a lower screen net body. The upper screen net body is composed of a left half net body and a right half net body which form an included angle of 176 degrees, and is provided with a plurality of first through holes and a plurality of transverse corrugated protrusions. The diameter of the first through holes is 3 mm larger than the diameter of the mature peony seeds. The height and the thickness of all the transverse corrugated protrusions are 3 mm. The lower screen net body is provided with second through holes of which the diameter is 2 mm. The screen body is provided with a front rotating shaft and a back rotating shaft. A transmission mechanism is arranged between the front rotating shaft and the back rotating shaft. Two sets of material spreading and flow guiding devices are arranged on the transmission mechanism with each comprising a material spreading plate composed of a left push plate and a right push plate which form an included angle of 150 degrees and a flow guiding plate composed of a left guide plate and a right guide plate which form an included angle of 150 degrees. The bottoms of the material spreading plates and the bottoms of the flow guiding plates are matched with the top surface of the upper screen net body in shape. The distance between the bottoms of the material spreading plates and the top surface of the upper screen net body as well as the distance between the bottoms of the flow guiding plates and the top surface of the upper screen net body are 12 mm. The impurity removing rate can be reached only by screening the peony seeds for one time, and thus the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to equipment used for removing impurities from seeds, in particular to a vibrating screen for removing impurities from peony seeds. Background technique [0002] Peony seed oil has to go through many processes in the production and processing process, and the impurity removal process is the first process, which is also a very important process. The rate of impurity removal will directly affect the subsequent oil yield of peony seeds and the taste of the oil. At present, in the impurity removal process of peony seeds, vibrating screens are generally used to screen them. The conventional vibrating screens are mostly composed of a screen body and a screen mesh. The screen body is elastically connected to the frame through the spring at the bottom, and the motor is installed on the The vibrator installed on the sieve body is driven by the belt and pulley to vibrate the sieve body, so as to achieve the purpose of screening peony seeds....

AI Technical Summary

Problems solved by technology

Although this kind of vibrating sieve has been widely used in the screening process of peony seeds, its screening effect is not very ideal, and the impurity removal rate is not high. , it usually needs to repeat the impurity removal cycle several times to barely reach the impurity removal rate of peony seeds, which shows that the efficiency is very low
