[0021] See also Figures 1 to 7 , the peanut oil residue filtering and re-pressing device provided by the present invention is now described. The peanut oil residue filtering and re-pressing device comprises a frame 10, a re-pressing filter cartridge 20 and a pressing plate 30. The lower part of the frame 10 is provided with a first telescopic member 11 extending upward; the re-pressing filter cartridge 20 is arranged at the upper end of the first telescopic member 11 and has an upward opening for accommodating peanut residues. The inner bottom of the re-pressing filter cartridge 20 is provided with oil paper for filtering peanut residues, and the lower part of the re-pressing filter cartridge 20 is provided with an oil receiving cylinder 40 for receiving the peanut oil filtered out in the re-pressing filter cartridge 20; the pressing plate 30 is arranged at the upper part of the frame 10 and located above the re-pressing filter cartridge 20, and is used to cooperate with the re-pressing filter cartridge 20 to squeeze the peanut residue in the re-pressing filter cartridge 20 when the re-pressing filter cartridge 20 moves upward.

[0022] Optionally, the oil paper is in a rectangular shape.

[0023] Optionally, the oil paper is in a circular shape.

[0024] Optionally, the oil paper is in a tube shape.

[0025] The embodiment of the present application provides a peanut oil residue filtering and re-pressing device. During its actual use, rectangular oil paper is first laid in the re-pressing filter cylinder 20, and peanut oil with peanut residue is poured on the oil paper. The peanut oil passes through the rectangular oil paper and the re-pressing filter cylinder 20 and enters the oil receiving cylinder 40 in turn. All the peanut residue remains on the oil paper. The four corners of the oil paper are folded in turn to wrap the peanut residue inside. Finally, the first telescopic member 11 drives the re-pressing filter cylinder 20 to move upward, so that the pressure plate 30 squeezes the peanut residue in the oil paper, thereby squeezing out all the peanut oil in the peanut residue, thereby avoiding the waste of peanut oil.

[0026] Compared with the prior art, the peanut oil residue filtering and re-pressing device provided in this embodiment filters peanut oil through oil paper, so that peanut residue remains on the oil paper, and the peanut residue is wrapped with oil paper. The first telescopic member 11 drives the re-pressing filter cylinder 20 to move upward, so that the pressing plate 30 squeezes the peanut residue in the oil paper to release the residual peanut oil, thereby realizing repeated squeezing of peanut crumbs and avoiding waste of peanut oil.

[0027] In a possible implementation, the re-squeezing filter cartridge 20 is Figures 1 to 5 The structure shown, see Figures 1 to 5 The top of the re-squeezing filter cartridge 20 is hinged with a paper folding plate 50 that can swing vertically. Four paper folding plates 50 are arranged at intervals in the circumferential direction of the re-squeezing filter cartridge 20. The oil paper is rectangular in shape, and the four corners are arranged one by one with the four paper folding plates 50. The four paper folding plates 50 can be swung into the re-squeezing filter cartridge 20 in sequence to fold the oil paper.

[0028] Specifically, after the oil paper is placed on the inner wall of the re-squeezing filter cylinder 20, the four corners of the oil paper are higher than the vertical folding paper pressing plate 50, that is, the oil paper is of large specifications. When placing the oil paper, the four corners of the oil paper are respectively placed on the inner side walls of the four folding paper pressing plates 50, and one of the folding paper pressing plates 50 is first lowered to fold the corresponding corner of the oil paper, and the folding paper pressing plate 50 is reset, and then the other folding paper pressing plates 50 are lowered in this way, and the four corners of the oil paper are folded, so that the peanut residue is wrapped in the oil paper, so as to avoid the peanut residue falling into the oil receiving cylinder 40 or sticking to the pressing plate 30 when squeezing the peanut residue in the later stage, which not only realizes the repeated squeezing of the peanut residue, but also further filters the peanut oil and improves the cleanliness of the peanut oil.

[0029] In some embodiments, see Figures 1 to 5 A traction member 60 is provided on the outer side of the re-squeezing filter cylinder 20 . The traction member 60 is connected to the paper folding pressing plate 50 through a traction rope 62 , and is used to pull the paper folding pressing plate 50 to swing upward.

[0030] Specifically, the four corners of the oil paper are respectively attached to the inner walls of the four paper folding press plates 50. When the paper folding press plate 50 is needed to fold the oil paper, the traction member 60 releases the paper folding press plate 50, and the paper folding press plate 50 swings down under the action of its own gravity to fold the oil paper. After the folding is completed, the traction member 60 pulls the paper folding press plate 50 to swing upward, thereby resetting the paper folding press plate 50 to avoid interfering with the later pressure plate 30 squeezing the peanut residue in the oil paper, thereby realizing the automatic folding of the oil paper.

[0031] Optionally, the traction member 60 is a cylinder, which is disposed on the outer peripheral wall of the re-squeezing filter cartridge 20 and extends outward and upward, and the traction rope 62 is connected to the extended end of the cylinder.

[0032] Optionally, an extension arm 22 extending outward and upward is provided on the outer peripheral wall of the re-squeezing filter cartridge 20, and a guide wheel 23 extending horizontally from the main shaft is rotatably connected to the extension arm 22. The traction rope 62 is wound around the outer periphery of the guide wheel 23. A boss 21 protruding toward the outer periphery is provided on the lower outer peripheral wall of the re-squeezing filter cartridge 20. The traction member 60 is arranged on the upper end surface of the boss 21. The traction member 60 includes a traction motor 61 and a rope winding roller 63. The traction motor 61 is arranged on the upper end surface of the boss 21 and has a horizontally extending driving end; the rope winding roller 63 is connected to the driving end of the traction motor 61, and one end of the traction rope 62 is connected to the rope winding roller 63 and the other end is connected to the outer wall of the paper folding plate 50.

[0033] Furthermore, four traction members 60 are provided and are arranged in one-to-one correspondence with the four paper folding pressing plates 50 .

[0034] Specifically, the four traction members 60 respectively control the swinging of the four paper folding pressing plates 50, so that the four paper folding pressing plates 50 can be easily swung in sequence to fold the oil paper, thereby improving the convenience of use.

[0035] When the paper-folding pressing plate 50 needs to be swung downward, the traction member 60 is started to release the traction rope 62. The paper-folding pressing plate 50 swings downward under the action of its own gravity to fold the corresponding corners of the oil paper. Then the traction member 60 pulls the paper-folding pressing plate 50 upward to reset through the traction rope 62. Then, other paper-folding pressing plates 50 are swung downward in this way to fold the four corners of the oil paper, thereby wrapping the peanut residue in the oil paper. This prevents the peanut residue from falling into the oil cylinder 40 or sticking to the pressing plate 30 when the peanut residue is squeezed in the later stage. This not only realizes the repeated squeezing of the peanut residue, but also further filters the peanut oil, thereby improving the cleanliness of the peanut oil.

[0036] In some embodiments, see Figures 1 to 5An extension arm 22 extending outward and upward is provided on the outer peripheral wall of the re-squeezing filter cylinder 20, and a guide wheel 23 with a main shaft extending horizontally is rotatably connected to the extension arm 22. A traction rope 62 is wound around the outer periphery of the guide wheel 23. The traction member 60 includes a traction motor 61 and a rope winding roller 63. The traction motor 61 is arranged on the outer side of the re-squeezing filter cylinder 20 and has a horizontally extending driving end; the rope winding roller 63 is connected to the driving end of the traction motor 61, and one end of the traction rope 62 is connected to the rope winding roller 63 and the other end is connected to the outer wall of the paper folding plate 50.

[0037] Specifically, a boss 21 protruding toward the periphery is provided on the lower peripheral wall of the re-squeezing filter cartridge 20, and a traction member 60 is provided on the upper end surface of the boss 21. The boss 21 is provided for installing the traction member 60. The guide wheel 23 is used to guide the traction rope 62, and prevent the traction rope 62 from having hard friction with the extension arm 22, thereby effectively ensuring the service life of the traction rope 62. A circumferentially extending limiting groove is provided on the peripheral wall of the guide wheel 23, and the limiting groove is provided near the middle of the guide wheel 23. The traction rope 62 is located in the limiting groove, thereby preventing the traction rope 62 from detaching from the guide wheel 23.

[0038] When the paper folding plate 50 needs to swing downward, the traction motor 61 is started to drive the rope winding roller 63 to rotate, and the traction rope 62 is unwound. The paper folding plate 50 swings downward under the action of its own gravity to fold the corresponding corners of the oil paper. Then the traction motor 61 rotates in the opposite direction to rewind the traction rope 62, pulls the paper folding plate 50 to swing up and reset this paper folding plate 50, and then swings down other paper folding plates 50 in this way, folding the four corners of the oil paper, thereby wrapping the peanut residue in the oil paper, preventing the peanut residue from falling into the oil cylinder 40 or sticking to the pressure plate 30 when squeezing the peanut residue in the later stage. Not only does it achieve repeated squeezing of the peanut residue, but it also further filters the peanut oil and improves the cleanliness of the peanut oil.

[0039] In some embodiments, see Figures 1 to 6 A positioning cylinder 70 is provided on the upper part of the extension arm 22 and extends radially along the re-squeezing filter cylinder 20 and is used to abut against the outer wall of the paper folding press plate 50. The opening of the positioning cylinder 70 is set toward the axis of the re-squeezing filter cylinder 20. A first magnet 71 is provided on the inner bottom wall of the positioning cylinder 70. A second magnet 51 for repelling the first magnet 71 is provided on the outer wall of the paper folding press plate 50. The second magnet 51 can enter the positioning cylinder 70.

[0040] Specifically, the positioning cylinder 70 is located above the guide wheel 23 to avoid interference with the traction rope 62 wound around the guide wheel 23. In order to avoid interference with the pressing plate 30 squeezing the peanut residue when the origami pressing plate 50 is not in use, the origami pressing plate 50 is usually swung to a vertical state and limited by the positioning cylinder 70. When the origami pressing plate 50 is swung to a vertical state, it just abuts against the end face of the positioning cylinder 70, and the origami pressing plate 50 is limited to avoid its swing transition. When the origami pressing plate 50 abuts against the end face of the positioning cylinder 70, the second magnet 51 just enters the positioning cylinder 70, and at this time, there is a repulsive force between the first magnet 71 and the second magnet 51.

[0041] When the origami pressing plate 50 needs to be released, the traction member 60 unwinds the traction rope 62, and the repulsive force between the first magnet 71 and the second magnet 51 pushes the origami pressing plate 50 to swing downward, thereby avoiding the phenomenon that the origami pressing plate 50 is in a vertical state and cannot swing automatically, thereby improving the convenience of use.

[0042] In a possible implementation, the rack 10 is configured as follows: Figure 1 , Figure 2 and Figure 7 The structure shown, see Figure 1 , Figure 2 and Figure 7 An oil outlet cylinder 80 opening upward is provided at the upper part of the frame 10, and an oil outlet pipe 81 is connected to the bottom of the oil outlet cylinder 80. The pressure plate 30 is arranged at the bottom of the oil outlet cylinder 80 and below the oil outlet pipe 81. An oil hole 31 arranged opposite to the oil outlet pipe 81 is penetrated through the pressure plate 30.

[0043] Specifically, the oil hole 31 is used to avoid the peanut oil flowing out of the oil outlet pipe 81. When in use, firstly, a rectangular oil paper is laid in the re-pressing filter cylinder 20, and the peanut oil with peanut residue is poured into the oil outlet cylinder 80, and the peanut oil falls onto the oil paper through the oil outlet pipe 81, and the peanut oil passes through the rectangular oil paper and the re-pressing filter cylinder 20 into the oil receiving cylinder 40, and the peanut residue is all left on the oil paper, and the four corners of the oil paper are folded one by one to wrap the peanut residue, and finally the first telescopic member 11 drives the re-pressing filter cylinder 20 to move upward, so that the pressing plate 30 squeezes the peanut residue in the oil paper, thereby squeezing out all the peanut oil in the peanut residue, and avoiding the waste of peanut oil.

[0044] In some embodiments, see Figure 1 , Figure 2 and Figure 7 An upwardly arched arc platform 24 is provided on the inner bottom wall of the re-squeezing filter cartridge 20 , and the arc platform 24 can enter the oil hole 31 driven by the re-squeezing filter cartridge 20 .

[0045] Specifically, the arc-shaped platform 24 is provided to guide the peanut oil falling into the re-pressing filter cylinder 20, to avoid the accumulation of peanut residues on the arc-shaped platform 24, to ensure that the pressing plate 30 can squeeze all the peanut residues, and to improve the oil extraction effect.

[0046] When in use, first lay rectangular oil paper in the re-pressing filter cartridge 20 and wrap the arc platform 24, leaving a margin of oil paper at the arc platform 24 for the pressing plate 30 to squeeze, even if the oil paper at the arc platform 24 is loose, to avoid damage to the oil paper when the pressing plate 30 squeezes the peanut residue, then pour the peanut oil with peanut residue into the oil outlet cylinder 80, the peanut oil falls onto the oil paper through the oil outlet pipe 81, the peanut oil passes through the rectangular oil paper and the re-pressing filter cartridge 20 into the oil receiving cylinder 40, all the peanut residue remains on the oil paper, the four corners of the oil paper are folded one by one, so that the peanut residue is wrapped inside, and finally the first telescopic member 11 drives the re-pressing filter cartridge 20 to move upward, so that the pressing plate 30 squeezes the peanut residue in the oil paper, thereby squeezing out all the peanut oil in the peanut residue, avoiding the waste of peanut oil.

[0047] In some embodiments, see Figure 1 , Figure 2 and Figure 7 A mounting frame 82 is provided at the top of the oil outlet cylinder 80, and a pressing filter cartridge 90 located in the oil outlet cylinder 80 is suspended on the mounting frame 82 through a hanger 91. The pressing filter cartridge 90 is coaxially arranged with the oil outlet cylinder 80, and a second telescopic member 92 extending downward is provided at the top of the hanger 91. A pressing plate 93 for squeezing peanuts in the pressing filter cartridge 90 is connected to the lower end of the second telescopic member 92.

[0048] Specifically, the peripheral wall of the pressing filter cartridge 90 is penetrated with a second filter hole 95. When in use, a rectangular oil paper is first laid in the re-pressing filter cartridge 20, and the peanuts to be pressed are poured into the pressing filter cartridge 90. The second telescopic member 92 drives the pressing plate 93 to move downward to perform the initial pressing of the peanuts. The pressed peanut oil enters the oil outlet cylinder 80 from the second filter hole 95, and the peanut oil falls onto the oil paper through the oil outlet pipe 81. The peanut oil passes through the rectangular oil paper and the re-pressing filter cartridge 20 and enters the oil receiving cylinder 40. All the peanut residues remain on the oil paper. The four corners of the oil paper are folded one by one to wrap the peanut residues. Finally, the first telescopic member 11 drives the re-pressing filter cartridge 20 to move upward, so that the pressing plate 30 squeezes the peanut residues in the oil paper, thereby squeezing out all the peanut oil in the peanut residues, thereby avoiding the waste of peanut oil.

[0049] In some embodiments, see Figure 1 , Figure 2 and Figure 7 The hanger 91 cooperates with the mounting frame 82 to rotate circumferentially and is used to drive the filter press cartridge 90 to rotate circumferentially. The hanger 91 is connected to a rotating driving member 94 for driving the hanger 91 to rotate.

[0050] Specifically, the top of the mounting frame 82 has an annular disk, and the inner peripheral wall of the annular disk is provided with an annular groove 821 extending circumferentially, and the hanger 91 is slidably connected in the annular groove 821 and can rotate circumferentially around the annular groove 821. The rotary drive member 94 is provided at the top of the mounting frame 82 and has a driving end extending downward, and the driving end of the rotary drive member 94 is connected to the hanger 91 to drive the hanger 91 to rotate.

[0051] When in use, first lay rectangular oil paper in the re-pressing filter cartridge 20, and pour the peanuts to be pressed into the pressing filter cartridge 90, the second telescopic member 92 drives the pressing plate 93 to move downward, and the peanuts are pressed for the first time. The pressed peanut oil enters the oil outlet cylinder 80 from the second filter hole 95, and the peanut oil falls onto the oil paper through the oil outlet pipe 81. In order to allow the peanut oil in the pressing filter cartridge 90 to completely enter the oil outlet cylinder 80, the rotating drive member 94 is started to drive the pressing filter cartridge 90 to rotate centrifugally, so that all the peanut oil in the pressing filter cartridge 90 is thrown out, thereby improving the peanut oil extraction effect.

[0052] Furthermore, because the second telescopic member 92 and the pressing filter cartridge 90 are both mounted on the hanger 91 , when the second telescopic member 92 drives the pressing plate 93 to press the peanuts, no pressure is applied to the driving end of the rotating driving member 94 , thereby effectively protecting the rotating driving member 94 .

[0053] In a possible implementation, the re-squeezing filter cartridge 20 is Figures 1 to 3 The structure shown, see Figures 1 to 3 A first filter hole 25 is penetrated through the bottom wall of the re-squeezing filter cartridge 20. The first filter hole 25 is arranged close to the inner peripheral wall of the re-squeezing filter cartridge 20 and extends along the circumference of the re-squeezing filter cartridge 20 for allowing peanut oil to pass through.

[0054] Specifically, the first filter hole 25 avoids the force-applying surface of the pressure plate 30 , thereby preventing the oil paper above the first filter hole 25 from being damaged during the extrusion process.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
