[0051] As a preferred embodiment, a low-temperature oil pressing and refining method with a multiple automatic residue filtering structure comprises the following steps:

[0052] Step 1: First, the oil pressing particles 11 are respectively conveyed into the interior of the supply boxes 4 on both sides, and then the spiral feeding hoses 25 in the first feeding assembly 8 and the second feeding assembly 9 of the feeding mechanism 2 convey the oil pressing particles 11 into the interior of the supply box 10 through the internal spiral rotation process, and the oil pressing particles 11 are allowed to fall freely in the interior of the supply box 10, and then the exhaust fan extracts the air in the dust delivery chamber 13 through the first dust suction pipe 12, and then the second dust suction pipe 1201 connected to the dust delivery chamber 13 sucks the tiny particles in the oil pressing particles 11 into the interior of the dust delivery chamber 13 through the second dust suction pipe 1201 when the oil pressing particles 11 continue to fall freely, and then the tiny particles in the dust delivery chamber 13 are extracted through the first dust suction pipe 12, so that when the oil pressing particles 11 are accumulated, their tiny particles will not adhere to the oil seepage filter 14 and clog it;

[0053] Step 2: When the oil-pressing particles 11 are filled in the squeezing tube 22, the sealing frame 19 rotates through the sealing ring 21 of the motor belt in the motor room 20, and the pressurized oil cylinder 16 drives the squeezing rod 23 to move, and squeezes the oil-pressing particles 11 in the two groups of squeezing rods 23, and then the squeezed oil drips into the collection box 603 of the dry material separation component 6 through the oil seepage filter 14, and then the squeezing rod 23 with the pressurized oil cylinder 16 is separated, and the oil seepage filter 14 under the squeezing rod 23 is driven to separate by the left squeezing rod 23, and then the oil residue falls into the collection box 603 and waits for collection;

Then when the grease enters the interior of the pressurized bracket 701 and continues to fill the spiral slag filter shell 704, the electric valve 705 is closed at this time, driven by the hydraulic rod 703, and squeezes the grease in the pressurized bracket 701, so that the grease in the spiral slag filter shell 704 is squeezed, and the grease in the first separation chamber 30 is pressurized and passes through the sealing filter screen 29, so that the grease passes through the finer sealing filter screen 29, so that the grease that has completed the filtration flows to the storage chamber 5 through the second separation chamber 31, so that the grease is deposited and stored in the storage chamber 5.

[0056] The working process of the present application is as follows: first, the oil pressing particles 11 are respectively conveyed into the interior of the supply boxes 4 on both sides, and then the spiral feeding hoses 25 in the first feeding assembly 8 and the second feeding assembly 9 of the feeding mechanism 2 convey the oil pressing particles 11 into the interior of the supply box 10 through the internal spiral rotation process, and the oil pressing particles 11 are allowed to fall freely in the interior of the supply box 10, and then the exhaust fan extracts the air in the dust delivery chamber 13 through the first dust suction pipe 12, and then the second dust suction pipe 1201 connected to the dust delivery chamber 13 sucks the tiny particles in the oil pressing particles 11 into the interior of the dust delivery chamber 13 through the second dust suction pipe 1201 when the oil pressing particles 11 continue to fall freely, and then the tiny particles in the dust delivery chamber 13 are extracted through the first dust suction pipe 12, so that when the oil pressing particles 11 are accumulated, their tiny particles will not adhere to the oil seepage filter 14 and clog it;

[0057] Then, when the oil-pressing particles 11 are filled in the squeezing tube 22, the sealing frame 19 rotates through the sealing ring 21 of the motor belt in the motor room 20, and the pressurized oil cylinder 16 drives the squeezing rod 23 to move, and squeezes the oil-pressing particles 11 in the two groups of squeezing rods 23, and then the squeezed oil drips into the collection box 603 of the dry material separation component 6 through the oil seepage filter 14, and then the squeezing rod 23 driven by the pressurized oil cylinder 16 is separated, and the oil seepage filter 14 under the squeezing rod 23 is driven to separate by the left squeezing rod 23, and then the oil residue falls into the collection box 603 and waits for collection;

[0058] Then, after the residue receiving chamber 604 in the collecting box 603 has completed the collection of the oil residue, the oil is filtered through the residue separation net 607 in the residue receiving chamber 604, and then filtered into the oil flow groove 608, and then stored in the oil collecting chamber 605 through the oil flow groove 608. While the oil is being stored, the connecting pipe 709 connected to the oil pump 708 is connected to the oil extraction pipe 606, and the oil is extracted from the storage tank 706.

[0059] Then the oil flows downward in the storage tank 706, and in the process of flowing, the oil contacts the separation bracket 707, and the oil is filtered through the separation bracket 707, and the filtered oil enters the interior of the pressurized bracket 701, and then when the oil enters the interior of the pressurized bracket 701 and continues to fill the spiral slag filter shell 704, the electric valve 705 is closed at this time, driven by the hydraulic rod 703, and squeezes the oil in the pressurized bracket 701, so that the oil in the spiral slag filter shell 704 is squeezed, and the oil in the first separation chamber 30 is pressurized and passes through the sealing filter screen 29, so that the oil passes through the finer sealing filter screen 29, so that the oil that has completed the slag flows through the second separation chamber 31 to the storage chamber 5, so that the oil is deposited and stored in the storage chamber 5. The above is the working principle of the low-temperature oil pressing and refining equipment and method with multiple automatic slag filtering structures.
