[0005] (1) Flaxseed oil is extracted by squeezing with a pressure pump, and flaxseed cannot be repeatedly cold-pressed, resulting in a low oil yield of flaxseed, which easily leads to waste of flaxseed, and inconvenience in removing flaxseed residue;
[0006] (2) Since the ground linseed oil will be discharged from the oil outlet, it is still inevitable that the linseed will enter the inside of the oil outlet and cause the oil outlet to be blocked, thus affecting the smoothness of the oil outlet. Utility Model Content
[0007] In view of the deficiencies in the prior art, the utility model provides a raw material purification device for low-temperature cold pressing of linseed oil, which has the advantages of improving the oil yield of linseed, conveniently discharging residues, and effectively avoiding blockage of oil outlet holes causing oil outflow problems, thereby solving the problems raised in the background technology.

[0009] Preferably, one end of the partition is rotatably connected to a grinding wheel, one side of the turning fork is in contact with the inner wall of the grinding box, and a plurality of through grooves are formed on the surface of the turning fork.
[0010] Preferably, both side surfaces of the discharge box are fixedly connected with a fixing plate, a threaded rod is threadedly inserted into the surface of the fixing plate, the top of the threaded rod is rotatably connected with an L-shaped plate, both sides of the lower surface of the L-shaped plate are fixedly connected with a limiting rod, and the limiting rod is slidably inserted into the fixed plate.
[0011] Preferably, the bottom ends of the side walls on both sides of the bottom leakage box are rotatably connected to limit frames, and the limit frames are consistent with the model and specifications of the L-shaped plate.
[0012] Preferably, a movable bar is provided inside the bottom leakage box, and a plurality of push rods are fixedly connected to the top of the movable bar. The push rods correspond to the positions of the oil outlet holes and are consistent in model and specification.

[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] 1. By starting the motor, flax seeds are injected into the grinding box from the feed port. The motor can drive the rotating rod to rotate inside the grinding box. The rotating rotating rod drives the partition to rotate inside the grinding box, so that the grinding wheel grinds the flax seeds in the grinding box to produce oil. After being ground and pressed, the flax seeds will adhere to the inner wall of the grinding box, and the adhered flax seeds will be loosened by the rotating turning fork, and then repeatedly ground by the grinding wheel, thereby greatly improving the oil yield of the flax seeds. While grinding the flax seeds, the bottom leakage box is always installed inside the discharge box, and the top of the bottom leakage box is seamlessly matched with the inner wall of the grinding box, thereby greatly reducing the impact of grinding the flax seeds. When the grinding is completed, the threaded rod can be manually rotated to drive the L-shaped plate to move, thereby releasing the clamping state with the limit frame, and then the limit frame is rotated. At this time, the bottom leakage box can be taken out from the inside of the discharge box, which is convenient for discharging the residue in the grinding box. The device is simple and quick to operate, not only greatly improving the oil yield of the flax seeds, but also convenient for discharging the residue, which is conducive to practical promotion and use.
[0016] 2. By setting the moving bar, since the ground linseed oil will be discharged from the inside of the oil outlet hole, and since the linseed will accumulate on the upper surface of the bottom leakage box, although there is a turning fork to loosen the ground linseed, it is still inevitable that the linseed will enter the inside of the oil outlet hole and cause the oil outlet hole to be blocked, affecting the smoothness of the oil outlet. When the smoothness of the oil outlet is affected, the handle can be manually turned to drive the moving bar to move inside the discharge box, and the push rod can be driven to move synchronously, so that the linseed blocked in the oil outlet hole can be pushed out, ensuring the smooth oil storage in the oil outlet hole, effectively avoiding the situation of oil outlet blockage causing oil outflow, and improving the cold pressing efficiency of linseed oil.
