Problems solved by technology

[0003] The oil in the rapeseed is obtained by pressing the rapeseed, and the harvested rapeseed is mixed with a lot of impurities such as rapeseed hulls and straw powder. In order to improve the quality of the rapeseed oil obtained by pressing the rapeseed, in the rapeseed Rapeseed needs to be sieved to remove impurities before seed pressing, but the current sieving and removing impurities device only sieves rapeseed through the sieve, the effect of removing impurities is poor, and the workload is large, which cannot meet the actual production needs. , to this end, a rapeseed screening and impurity removal device for rapeseed oil production is now provided to solve the above technical problems

Embodiment 1

[0024] see Figure 1-6 , a rapeseed screening and impurity removal device for rapeseed oil production, comprising a support frame 1, a sieve groove 16 is hinged on the support frame 1, a sieve plate 13 is embedded in the bottom of the sieve groove 16, and a sieve plate 13 is installed above the sieve groove 16. There is a feeding bucket 2 fixed on the inner top of the support frame 1, and a feeding hopper 4 is connected and installed on the feeding bucket 2. Several scattered radial holes 26 are evenly opened on the bottom of the feeding bucket 2, and the side walls of the sieve groove 16 are fixed. There is a fixed frame 10, the bottom of the fixed frame 10 is fixed with a limit sleeve 21, a sliding column 23 is installed in the limit sleeve 21, and the lower end of the sliding column 23 is rotatably provided with a guide roller 24, and the support frame 1 is slidably installed with a guide roller 24 abutting wedge block 25, below the sieve trough 16 is provided with a collec...

Embodiment 2

[0030] In order to speed up the removal rate of impurities in rapeseed, on the basis of Embodiment 1, in addition, a drive motor 11 is fixed in the fixed frame 10, a pair of fan blades 9 are fixed on the output shaft of the drive motor 11, and the side wall of the sieve groove 16 is embedded. A screen plate 8 opposite to the fan blade 9 is provided, and a bellows 17 extending to the outside of the support frame 1 is embedded and installed on the side wall of the screen trough 16 opposite to the screen plate 8 .

[0031] When the sieve plate 13 sieves the rapeseed, the impurities stay in the sieve groove 16. At the same time, the driving motor 11 drives the fan blade 9 to rotate, and the fan blade 9 performs a horizontal blowing effect to the inside of the sieve groove 16. The specific gravity of impurities in the seeds is relatively light, and the airflow generated by the fan blades 9 blows the impurities away from the sieve groove 16, and the airflow carries the impurities int...

Abstract

The invention discloses a rapeseed screening and impurity removal device for production of rapeseed oil and relates to the technical field of rapeseed oil processing. The device comprises a supportingframe, wherein a screening groove is hinged to the supporting frame; a screening plate is embedded in the bottom of the screening groove; a material separation barrel fixed at the top in the supporting frame is arranged above the screening groove; a limiting sleeve is fixed at the bottom of a fixed frame; a sliding column is mounted in the limiting sleeve; a wedge block abutted against the a guiding roller is slidably mounted on the supporting frame; and a collecting groove fixed on the supporting frame is arranged below the screening groove. According to the invention, through the transmission cooperation of the arranged wedge block and the guiding roller, the vibration of the screening groove together with the screening plate is achieved and thus separation of rapeseeds and impurities is facilitated; arranged fan blades rotate and blow air towards the interior of the screening groove, so that light impurities mixed in the rapeseeds are blown away and the separation effect of the rapeseeds and impurities is better; and arc holes formed in a discharging disc are staggered with disperse radial holes formed in the material separation barrel intermittently and repeatedly, so that excessive concentrated screening of the rapeseeds is avoided and the impurity removal efficiency is improved greatly.

Description

technical field [0001] The invention relates to the technical field of rapeseed oil processing, in particular to a rapeseed screening and impurity removal device for rapeseed oil production. Background technique [0002] Rapeseed oil is what we commonly call rapeseed oil, also known as rapeseed oil, coriander oil, canola oil, sesame oil, and canola oil. It is a kind of edible oil squeezed out of rapeseed. It is one of the main edible oils in my country. In the Yangtze River Basin, Southwest, Northwest and other places, the output ranks first in the world. The color of rapeseed oil is golden or brown, and it has a certain pungent smell. The folks call it "green smell". substance. [0003] The oil in the rapeseed is obtained by pressing the rapeseed, and the harvested rapeseed is mixed with a lot of impurities such as rapeseed husks and straw powder. In order to improve the quality of the rapeseed oil obtained by pressing the rapeseed, in the rapeseed Rapeseed needs to be si...
