Description

Technical Field

[0001] The invention relates to the field of castor seed processing, in particular to a device for crushing and grinding castor seeds, a raw material of a diesel antiwear agent. Background Art

[0002] Castor oil can be obtained after castor seeds are squeezed. Castor oil can be mixed with other ingredients (such as polyglycerol) and reacted under the action of a catalyst to produce a diesel anti-wear agent with excellent lubrication effect and low freezing point. In the prior art, castor beans, the raw material of castor oil, need to be air-dried after being picked. The air-dried castor beans are shelled manually or by machine, and then the shelled castor seeds are screened for oil extraction. Traditionally, castor shelling and screening are mostly handled separately, which makes the castor shelling process more complicated. It is difficult to perform castor feeding, shelling and screening simultaneously to achieve simultaneous processing of multiple tasks and improve overall work efficiency. In addition, castor seeds need to be crushed and ground before oil extraction. The crushed seed particles are smaller and the surface area is increased, which is conducive to the extraction and separation of oil. The cell wall and internal structure of the seeds will be destroyed during the crushing process, making it easier for oil to be released from the cells. Most castor seed crushing devices crush them by hammer mills, and the efficiency of crushing with a crusher alone is poor.

At this time, the castor shells and castor seeds separated by the first crushing roller 53 and the second crushing roller 54 pass between the first guide block 26 and the second guide block 27. Then the wind passes between the first guide block 26 and the second guide block 27 and is discharged at the discharging inclined bucket 28.

[0027] A hammer mill 8 is also provided on one side of the shell 2. A driving motor 81 is provided on one side of the hammer mill 8. The driving shaft of the driving motor 81 is connected to the driving shaft of the hammer mill 8 through a pulley assembly 4.

[0029] The working process and principle of the present invention are as follows: When in use, firstly, the air-dried castor is placed above the lower end of the baffle conveyor belt 14, and then the first stepper motor 51 is started. The first stepper motor 51 drives the two centrifugal fans 58 to start synchronously through the pulley assembly 4, and the first stepper motor 51 drives the output shaft of the first reduction box 52 to rotate, and the output shaft of the first reduction box 52 drives the first crushing roller 53 to rotate, and the output shaft of the first reduction box 52 drives the roller 15 to rotate synchronously through the pulley assembly 4, and the roller 15 drives the baffle conveyor belt 14 to convey the castor to the top of the housing 2, and the first crushing roller 53 drives the second crushing roller 54 to rotate at the same speed and in the opposite direction through the first spur gear 55 and the second spur gear 56, so as to squeeze the castor delivered, so that the castor seeds and shells are separated, and the second crushing roller 54 and the first crushing roller 53 drive the brush roller 57 below them to rotate through the pulley assembly 4 when rotating, so as to clean the outer side of the second crushing roller 54 to prevent the castor shells from being stuffed into the gap in the second crushing roller 54; When the centrifugal fan 58 is started, the outside air is blown into the housing 2 through the air inlet slot 29. At this time, the castor shells and castor seeds separated by the first crushing roller 53 and the second crushing roller 54 pass between the first guide block 26 and the second guide block 27. Then, the wind passes between the first guide block 26 and the second guide block 27 and is discharged at the discharging hopper 28. At the same time, the light and irregular castor shells are blown out together, and the heavy and regular castor seeds fall between the first rolling roller 75 and the second rolling roller 76. When the air entrained with the castor shells flows into the box body 61 through the feed port 63, the castor shells fall into the inside of the collecting drawer 62, and the air is screened by the sieve plate 64 and discharged through the dust cover 65 and the dust pipe 66. After the castor seeds fall between the first rolling roller 75 and the second rolling roller 76, the second stepper motor 71 is started. When the second stepper motor 71 is started, the first rolling roller 75 is driven to rotate through the second reduction gear 72, and the first rolling roller 75 drives the second rolling roller 76 to rotate through the third spur gear 73 and the fourth spur gear 74, so that the first rolling roller 75 and the second rolling roller 76 rotate in the same speed and in the opposite direction, and then the castor seeds between the first rolling roller 75 and the second rolling roller 76 are pre-processed to be crushed. To facilitate the subsequent crushing, the crushed castor seeds fall into the interior of the hammer mill 8 through the feed box 82, and then the drive motor 81 is started to drive the hammer mill 8 to crush the castor seeds. The crushed castor seeds fall into the bottom of the inner wall of the hammer mill 8. When the drive motor 81 is started, it also drives the discharge fan 83 to run, so that the crushed castor seeds in the hammer mill 8 are sucked into the discharge fan 83 through the feed pipe 84, and then discharged through the discharge pipe 85 to complete the discharge.
