A support base 5 is arranged in the middle of the base 1. A filter screen 6 is sleeved on the top of the support base 5, which is used for preliminarily filtering the rapeseed oil liquid after pressing. A filter cylinder 7 is placed at the middle position on the top of the support base 5. The outer diameter of the pressing plate 4 is adapted to the inner diameter of the filter cylinder 7, and the filter cylinder 7 is located directly below the pressing plate 4. A limit frame 8 is arranged in the middle of the gantry 2, which is used for limiting the filter cylinder 7, and the filter cylinder 7 is detachably sleeved in the limit frame 8. When it is necessary to take out the filter cylinder 7, it can be taken out upward, which is convenient to use.

[0035] Refer to Figures 4 - 6 As shown in the figure, it includes a dregs separation device. The dregs separation device includes a collar 9, a filter ring 10, a servo motor 11, a small gear 12, and a large gear 13. A collar 9 is rotatably sleeved on the upper part of the support base 5. The periphery of the collar 9 is surrounded by a filter ring 10 that can be disassembled, which is beneficial to cleaning the disassembled filter ring 10 and is convenient to use. A large gear 13 is installed at the bottom of the collar 9, and the large gear 13 is sleeved outside the support base 5. A servo motor 11 is installed on the side wall of the support base 5. A small gear 12 is installed on the output shaft of the servo motor 11 through a coupling, and the small gear 12 meshes with the large gear 13, which is used to drive the collar 9 and the filter ring 10 to rotate, so as to achieve the purpose of separating the oil liquid from the impurities.

[0036] Refer to Figure 1 、 Figure 7 and Figure 8 As shown in the figure, it includes a filtering mechanism. The filtering mechanism includes a guide frame 14, a collector 15, a threaded adjusting rod 16, a filter net 17, and an oil outlet nozzle 18. A guide frame 14 is arranged on the left side in the middle of the base 1. A collector 15 that can slide up and down to adjust the height is slidably sleeved on the guide frame 14, and the collector 15 is sleeved outside the collar 9 and the filter ring 10. The inner bottom of the collector 15 is inclined with the rear higher than the front, which is used for concentrating the oil liquid after secondary impurity removal, so as to achieve the purpose of facilitating the collection of rapeseed oil liquid. A threaded adjusting rod 16 is rotatably installed on the right side in the middle of the base 1. The threaded adjusting rod 16 penetrates through the right part of the collector 15, and the collector 15 is threadedly connected with the threaded adjusting rod 16. A filter net 17 is embedded at the oil outlet at the front side of the bottom of the collector 15. The filter net 17 is a fine net, which is used for secondary filtering of the rapeseed oil liquid after dregs separation. An oil outlet nozzle 18 is installed at the front side of the bottom of the collector 15 and directly below the filter net 17.

[0037] First, lay the gauze 100 in the filter cylinder 7, then pour an appropriate amount of rapeseed into the filter cylinder 7. Start the hydraulic cylinder 3 and the servo motor 11 respectively. The hydraulic cylinder 3 drives the pressure plate 4 to extend downward with its hydraulic rod, so as to squeeze the rapeseed wrapped in the gauze 100 in the filter cylinder 7, thereby achieving the purpose of squeezing oil from the rapeseed. The squeezed rapeseed oil seeps along the outer wall of the filter cylinder 7 into the filter screen 6. Through the preliminary filtering effect of the filter screen 6, it is beneficial to preliminarily filter the impurities in the rapeseed oil. Under the driving action of the servo motor 11 and the transmission action of the small gear 12 and the large gear 13, the collar 9 and the filter ring 10 can be driven to rotate at a high speed, and the rapeseed oil filtered on the filter screen 6 can be separated from the oil residue, which is beneficial to improving the efficiency of removing impurities from the rapeseed oil. The rapeseed oil after oil residue separation will be thrown into the collector 15. Through the collection effect of the collector 15 and the secondary filtering effect of the filter net 17, the rapeseed oil flows out from the oil outlet nozzle 18. Just place a container for collecting rapeseed oil below the oil outlet nozzle 18. In this way, through multiple levels of impurity filtering and oil residue separation, the squeezed rapeseed oil is clear and bright, and there is no need to perform additional processing on the squeezed rapeseed oil, avoiding cumbersome processing procedures, and thus being beneficial to saving the cost of oil pressing.

[0038] When the rapeseed in the filter cylinder 7 is pressed and it is necessary to take out the rapeseed cake inside, the filter cylinder 7 can be pulled out upward. Since the bottom of the filter cylinder 7 is provided with a hollow structure, it is convenient to invert the filter cylinder 7 with the rapeseed cake on a wooden stake with a diameter smaller than that of the filter cylinder 7. The rapeseed cake can be assisted to separate from the filter cylinder 7 by knocking on the upper part of the filter cylinder 7, so as to achieve the purpose of quickly removing the cake. When it is necessary to clean the impurities in the filter ring 10, the threaded adjusting rod 16 can be rotated to make the collector 15 drive the components on it to slide downward, so that the filter ring 10 can be presented, which is convenient to disassemble and take out the filter ring 10, and is beneficial to cleaning the inside of the filter ring 10, and is convenient to use.

[0039] In one embodiment, referring to Figure 1 、 Figure 9 and Figure 10 as shown, it further includes a material control mechanism. The material control mechanism includes a support 19, a feeding hopper 20, a plug board 21 and a feeding nozzle 22. The support 19 is installed on the front side of the top of the gantry 2.

By pulling the plug board 21, the feeding amount of the rapeseed raw material can be controlled, which is beneficial to achieving the purpose of controlling the rapeseed raw material. The bottom of the feeding hopper 20 is connected to and communicated with the feeding nozzle 22.

[0040] Referring to Figure 1 、 Figure 9and Figure 10 As shown, it further includes a impurity removing mechanism. The impurity removing mechanism includes a box body 23, a blower 24, a material receiving nozzle 25 and a cloth bag 37. The lower part of the support 19 is assembled with the box body 23, and an opening communicating with the blanking nozzle 22 is provided at the top of the box body 23. The blower 24 is embedded and assembled at the rear side of the box body 23. The blower 24 is used for blowing air to blow away the impurities mixed in the rapeseed raw materials. An open-type material receiving nozzle 25 is installed inside the box body 23, and the material receiving nozzle 25 is located directly below the blanking nozzle 22.

The driving motor 28 is installed on the left front side of the crushing box 26, and the output shaft of the driving motor 28 is connected to one of the crushing rollers 27 through a coupling.

[0042] Refer to Figure 1 、 Figure 9 and Figure 10 As shown, it further includes a material guiding mechanism. The material guiding mechanism includes a material guiding hopper 30, a material receiving hopper 31 and a locking bolt 32. The material guiding hopper 30 is connected to the bottom of the crushing box 26. A slidably adjustable material receiving hopper 31 is sleeved on the side of the material guiding hopper 30 close to the filter cylinder 7. The discharge port of the material receiving hopper 31 is of a narrow-mouth structure, which is beneficial to guiding the rapeseed raw materials into the filter cylinder 7 to achieve the purpose of convenient feeding. Locking bolts 32 are threadedly penetrated through the left and right sides of the material receiving hopper 31, and the ends of the locking bolts 32 close to each other abut against the outer wall of the material receiving hopper 31 for locking and fixing the material receiving hopper 31.

[0043] Pour an appropriate amount of rapeseed into the feeding hopper 20. The feeding amount of rapeseed can be controlled by pulling out the insertion plate 21. Pull out and extend the receiving hopper 31 so that the discharge opening of the receiving hopper 31 can be located above the filter cylinder 7. Start the blower 24 and the drive motor 28 respectively. When the insertion plate 21 is pulled outwards, the rapeseed in the feeding hopper 20 can fall into the receiving nozzle 25 through the feeding nozzle 22. Through the blowing action of the blower 24, impurities or underfilled rapeseed in the falling rapeseed can be blown away, and the blown impurities can be collected through the cloth bag 37, which is conducive to further improving the quality of rapeseed impurity removal; the rapeseed that has fallen after impurity removal can be crushed by two crushing rollers 27. Under the guiding action of the guiding hopper 30 and the receiving hopper 31, it is convenient to directly collect the crushed rapeseed into the filter cylinder 7, which is conducive to forming a complete and smooth oil pressing process, and further improves the oil pressing efficiency.

[0044] In one embodiment, referring to Figure 1 、 Figure 11 and Figure 12 As shown, there is also an oil scraping mechanism. The oil scraping mechanism includes a bracket 33, a scraping ring 34, a guide rod 35 and an elastic member 36. There are two brackets 33 arranged at the lower rear side of the collector 15.

Compression springs are sleeved on the two guide rods 35, and one end of the elastic member 36 abuts against the bracket 33, and the other end abuts against the limiting frame 8. The elastic member 36 is a compression spring, which plays a role of buffering and resetting. A scraping ring 34 for scraping the oil adhered to the outer wall of the filter cylinder 7 is connected between the lower ends of the two guide rods 35.

[0045] When the threaded adjusting rod 16 is rotated to make the collector 15 slide downwards, it will drive the bracket 33 and the scraping ring 34 to slide downwards synchronously. Through the scraping action of the scraping ring 34 on the outer wall of the filter cylinder 7, the rapeseed oil adhered to the outer wall of the filter cylinder 7 can be scraped downwards, which is conducive to reducing the loss of rapeseed oil. At the same time of scraping oil, the outer wall of the filter cylinder 7 can also be cleaned, which is conducive to saving manpower.
