Rapeseed preliminary swinging screening device for rapeseed oil processing

Abstract

The invention discloses a rapeseed preliminary swinging screening device for rapeseed oil processing. The screening device comprises support frames and a screening barrel, wherein rocker bars are welded on the outer walls of two symmetrical sides of the screening barrel; the two rocker bars are rotatably connected with the side wall of the support frame on the corresponding side through bearings;and the inner wall of the screening barrel is slidably connected with a lower screen. The screening device has the advantages that an active magnetic block is welded to an output shaft of a power motor, a passive magnetic block is welded to the side wall of a discharging pipe, and one sides, mutually close to each other, of the active magnetic block and the passive magnetic block have opposite magnetic pole, so that under the rotation of the power motor, the active magnetic block continuously is able to push the discharging pipe to swing through magnetic force from two sides so as to enable the screening barrel to swing accordingly, and the rapeseed in the screening barrel is effectively screened by swing; and as a pushing device is designed, after the screening barrel swings for a certainnumber of times, a push rod can push an upper screen mesh so as to push impurities screened from the upper end of the screening barrel to be out of the screening barrel, and therefore subsequent processing can be continuously and effectively carried out.

Description

technical field [0001] The invention relates to the technical field of rapeseed screening, in particular to a rapeseed primary swing screening device for processing rapeseed oil. Background technique [0002] Rapeseed oil is an essential household item. Rapeseed oil is what we commonly call rapeseed oil, also known as rapeseed oil. It is a kind of edible oil squeezed from rapeseed and is one of the main edible oils in our country. [0003] The impurities in the rapeseed need to be cleaned before oil extraction, so as to avoid the existence of impurities that will lead to insufficient extraction of the rapeseed, resulting in a waste of resources. At present, the cleaning of impurities in the rapeseed is mostly carried out by means of swing screening , while the existing screening device cannot clean the impurities screened out in time during the rapeseed screening process, so that the subsequently added rapeseed is mixed with the screened out impurities, causing secondary pol...
