[0034] The material guiding component includes a hopper 10 and a sleeve 11. A plurality of leaks are opened on the side of the mesh cylinder 4. The hopper 10 is vertically fixedly installed on the top of the machine body 1. The sleeve 11 is rotatably sleeved on the leak area of ​​the mesh cylinder 4 and is fixedly connected to the bottom of the hopper 10.

[0035] The driving components include a motor 12, a driving gear 13 and two driven gears 14. The two driven gears 14 are fixedly sleeved on the screw 3 and the net cylinder 4 respectively. The motor 12 is vertically fixedly installed on the top of the body 1 and is electrically connected to the control device 2.

[0036] The device is powered on by the control device 2, and the motor 12 and the air pump device 39 are in operation. The motor 12 drives the two driven gears 14 to rotate simultaneously through the driving gear 13, and drives the screw 3 and the net cylinder 4 to rotate respectively.

[0037] When using this equipment to press oil from materials, the materials are put into the hopper 10, and the hopper 10 guides the materials into the lead groove of the screw 3 through the leakage area on the mesh cylinder 4. As the screw 3 rotates continuously, the materials are transported, and the depth of the lead groove of the screw 3 becomes shallower and shallower. The screw 3 and the mesh cylinder 4 squeeze the materials, so that the oil in the materials flows out through the mesh holes on the mesh cylinder 4, and finally flows along the oil leakage port 7 of the shell 5 to the guide plate 8 and flows into the storage mechanism.

[0038] When the screw 3 and the mesh cylinder 4 rotate, they rotate in the opposite direction synchronously. The mesh cylinder 4 and the screw 3 slide relative to the material, which can make the material move more smoothly while squeezing the material. At the same time, the mesh cylinder 4 can slide in contact with the brush plate 9 during the rotation process. The hard brush on the brush plate 9 penetrates into the mesh holes of the mesh cylinder 4 for cleaning, which can effectively avoid clogging of the mesh cylinder 4 and facilitate the discharge of oil.

[0039] The air pump device 39 operates to supply air to the air passage in the screw 3 through the air pipe 42. The airflow is finally discharged from the partition 41 in the multiple air holes 40 to disturb the material and further prevent blockage. At the same time, the airflow disperses outwards to bring out the oil, which is convenient for the discharge of the oil.

[0040] The temperature and output pressure of the air flow discharged by the air pump device 39 can be adjusted by the control device 2 according to demand, so as to facilitate heating and sufficient ventilation for processing operations of different materials.

[0041] The storage mechanism includes an oil pool 15, two brackets 16 and a valve 17. The two brackets 16 are vertically fixedly installed at the bottom of the body 1, the oil pool 15 is horizontally fixedly installed at the top of the two brackets 16, and the valve 17 is vertically fixedly installed at the bottom of the oil pool 15. A filter residue component is provided in the oil pool 15.

[0042] The filter residue component includes a main shaft 18, a rolling net 19, multiple impellers 20, multiple mesh plates 21, a scraper 22 and a storage box 23. The main shaft 18 is horizontally rotatably sleeved in the oil pool 15. The multiple impellers 20 are divided into two groups and are symmetrically fixedly sleeved on the main shaft 18. The rolling net 19 is horizontally fixedly sleeved on the outside of the multiple impellers 20. The multiple mesh plates 21 are all horizontally fixedly installed on the outside of the rolling net 19 and are evenly distributed in a ring shape. The mesh plates 21 are made of elastic material. The storage box 23 is fixedly installed on the upper front side of the oil pool 15, and covers 24 are installed at both ends. The scraper 22 is horizontally fixedly installed on the top of the rear side of the storage box 23. The rear side of the storage box 23 is provided with multiple fine holes, which are connected to the inside of the oil pool 15. The main shaft 18 is connected to the mesh cylinder 4 through a transmission component.

[0043] The transmission component includes two pulleys 25 and a transmission belt 26 . The two pulleys 25 are fixedly sleeved on the main shaft 18 and the net cylinder 4 respectively, and are connected by the transmission belt 26 .

[0044] After the oil flows out from the guide plate 8, it will flow into the oil pool 15 and be temporarily stored. The rotation of the mesh drum 4 drives the main shaft 18 to rotate through the pulley 25 and the transmission belt 26. The main shaft 18 drives multiple impellers 20 to rotate. The impeller 20 drives the rolling net 19 to rotate, disturbing the oil to facilitate its cooling. The rolling net 19 drives the mesh plate 21 located thereon to rotate to scoop out the residue in the oil. When the mesh plate 21 contacts the scraper 22, the filtered residue is intercepted by the scraper 22 and finally flows into the storage box 23, which can filter the oil to ensure the quality of the oil.

[0045] The impeller 20 drives the oil to flow in a counter-flowing manner, thereby allowing the oil to flow and preventing the residue from settling, thereby facilitating scooping and cleaning.

[0046] The compound pressure mechanism includes a cylinder 27, a pressure plate 28, a screw sleeve 29, a reciprocating screw rod 30, a dumping component and an adjusting component. The cylinder 27 is horizontally slidably installed in the inner wall of the body 1, the pressure plate 28 is slidably embedded in the cylinder 27, the screw sleeve 29 is horizontally fixedly installed on the left side of the pressure plate 28, the reciprocating screw rod 30 is horizontally fixedly installed on the right end of the main shaft 18, and is threadedly sleeved with the screw sleeve 29. The adjusting component is arranged at the right end of the cylinder 27 for adjusting the effective compression distance.

[0047] The dumping component includes a dump bucket 31 and a servo motor 32 . The servo motor 32 is fixedly mounted on the inner wall of the machine body 1 , and the dump bucket 31 is fixedly mounted on the output end of the servo motor 32 .

[0048] A filter plate 35 is slidably installed in the cylinder 27, and a plurality of springs 36 are horizontally fixedly installed between the filter plate 35 and the inner wall of the cylinder 27. The bottom of the cylinder 27 and the oil pool 15 are fixedly connected via a hose 37, and a one-way valve 38 is fixedly installed at the end of the hose 37. The one-way valve 38 conducts from the cylinder 27 to the oil pool 15.

[0049] The adjusting component includes a hand wheel 33 and a stud 34. The stud 34 is horizontally rotatably sleeved in the side wall of the body 1, and the end thereof is threadedly sleeved with the cylinder 27. The hand wheel 33 is fixedly installed on the outer end of the stud 34. According to the operation requirements of different materials, the hand wheel 33 is rotated to rotate the stud 34, and the stud 34 causes the cylinder 27 to move, thereby adjusting the effective distance between the filter plate 35 and the pressure plate 28, so as to achieve sufficient extrusion of different material residues.

[0050] A plurality of sharp thorn rods are fixedly mounted on one side of the pressing plate 28 away from the screw sleeve 29, and the pressing plate 28 moves slowly.

[0051] After the squeezed material is discharged from the output end of the mesh drum 4, it will fall into the inverted bucket 31. The servo motor 32 operates intermittently to pour the material residue into the cylinder 27. The main shaft 18 rotates, driving the reciprocating screw 30 to rotate. The reciprocating screw 30 drives the screw sleeve 29 to move back and forth. The screw sleeve 29 drives the pressure plate 28 to move back and forth in the cylinder 27 to squeeze the material residue into a cake shape, and perform secondary pressure filtration to fully squeeze out the residual oil and improve the oil yield. During the squeezing process, the pressure plate 28 squeezes the material residue onto the filter plate 35, and the spring 36 is compressed and finally pressed to the limit. The filter plate 35 cooperates with the pressure plate 28 to fully squeeze the material residue, and the oil flows out of the filter plate 35, flows into the hose 37 through the one-way valve 38, and finally flows into the oil pool 15.

[0052] After the re-pressing is completed, the pressing plate 28 moves away from the filter plate 35, and the spring 36 returns to its original length, so that the filter plate 35 pushes the slag cake to move. Finally, the slag cake moves out of the closed area of ​​the cylinder 27 along with the pressing plate 28 under the action of the piercing rod. The operator removes the slag cake to collect the material residue. At the same time, the servo motor 32 runs to deflect the bucket 31 and pour the slag into the exposed area of ​​the cylinder 27 for the next re-pressing operation.
