Description

Technical Field

[0001] The present invention relates to the technical field of grease purification and treatment, and in particular to a grease plasticizer removal device. Background Art

[0002] Plasticizer is a kind of polymer material additive, which is widely used in plastic products. Once oils and fats come into contact with plastic containers or equipment during the production, storage or packaging process, the plasticizers may dissolve into the oils and fats. For edible oils and fats, the plasticizers in the oils and fats may cause endocrine disorders, immune system diseases, reproductive system damage, liver diseases and other health problems. Therefore, for edible oils and fats, the plasticizers in them need to be removed.

[0003] The prior art discloses a plasticizer removal device (Announcement No.: CN 220056733U), which heats oil and fat and separates the plasticizer by utilizing the difference in boiling points between the plasticizer and the oil and fat. However, the heating process may cause the quality of the oil and fat to be damaged.

[0004] In traditional devices that use adsorption to remove plasticizers, plasticizers in oils and fats are captured by adsorbents. However, this method cannot completely remove the plasticizers through a single adsorption when the plasticizer concentration is too high. Summary of the Invention

DETAILED DESCRIPTION

[0060] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0061] like Figure 1-19 As shown, the present invention has the following four specific embodiments.

[0062] Example 1

[0063] A device for removing plasticizer from oil and fat comprises a central tube 1, wherein a base 11 is fixedly connected to the bottom of the central tube 1, and a removal chamber 12 is fixedly connected to the left and right sides and the rear side of the central tube 1. An oil outlet 13 and an oil inlet 14 are respectively provided on the central tube 1 at positions corresponding to the bottom and the top of the removal chamber 12. An oil drain port 15 is provided on the front side of the central tube 1 at a position at the same height as the inlet oil. An oil drain chamber 16 is fixedly connected to the oil drain port 15, and an oil drain pipe 17 is fixedly connected to the oil drain chamber 16. A collection box 18 is placed on the base 11, and the head of the oil drain pipe 17 extends into the collection box 18. An adsorbent 19 is provided in the removal chamber 12.

[0064] The grease plasticizer removal device also includes:

[0065] The sealing plate 2 is slidably connected to the outer wall of the central tube 1 and corresponds to the position of the oil outlet 13;

[0066] The transfer cylinder 3 is slidably connected to the center cylinder 1. The outer diameter of the transfer cylinder 3 is consistent with the inner diameter of the center cylinder 1. A center column 31 is fixedly connected to the center of the transfer cylinder 3. A partition 32 is fixedly connected between the center column 31 and the inner wall of the transfer cylinder 3. The partition 32 divides the transfer cylinder 3 into four chambers. The bottom of the side plate of the transfer cylinder 3 is provided with an oil outlet 33 corresponding to the position of each chamber.

[0067] The lifting mechanism is used to drive the transfer cylinder 3 to intermittently lift and lower. When the transfer cylinder 3 is at the bottom, the side plate of the rotating cylinder is located below the oil outlet 13, and the top of the sealing plate 2 is flush with the bottom plate of the removal chamber 12; when the transfer cylinder 3 is at the top, the oil port 33 is at the same height as the oil inlet 14 and the oil discharge port 15, and the sealing plate 2 closes the oil outlet 13.

[0068] Rotation mechanism: During the rising process of the transfer cylinder 3, the rotation mechanism is used to drive the transfer cylinder 3 to rotate 90° clockwise;

[0069] as well as

[0070] The quantitative adding mechanism is used to transport the grease to be processed to the leftmost chamber when the transfer cylinder 3 is located at the top.

[0071] In this embodiment, Figure 1-Figure 5 As shown, during the operation of the device, in the initial state, the transfer cylinder 3 is at the bottom (i.e. Figure 3 The top of the sealing plate 2 is flush with the bottom plate of the removal chamber 12, the oil outlet 13 is open, and the grease in each removal chamber 12 enters the chambers on the left and right sides and the rear side through the oil outlet 13, while the chamber on the front side is empty.

[0072] Under the action of the lifting mechanism, the transfer cylinder 3 rises. During this process, the rotating mechanism drives the transfer cylinder 3 to rotate 90° clockwise. When the transfer cylinder 3 reaches the top (i.e. Figure 4 The empty compartment on the front side moves to the left, and the compartment on the right side moves to the front side, as shown in FIG. Figure 6 As shown, the grease in the right chamber flows into the oil drain tank 16 from the oil passage 33 and the oil drain port 15 , and then flows into the collecting box 18 through the oil drain pipe 17 .

[0073] The transfer cylinder 3 will rotate when it rises. When the oil outlet 33 moves to a position equal to the oil outlet 13, the transfer cylinder 3 has rotated the moving angle, that is, the oil outlet 33 and the oil outlet 13 are staggered at this time, and the outer diameter of the transfer cylinder 3 is consistent with the inner diameter of the center cylinder 1, ensuring that the grease in each chamber will not leak out from the oil outlet 33 when the transfer cylinder 3 is raised or lowered.

[0074] When the transfer cylinder 3 moves to the top, the grease in the front chamber is discharged, and the grease in the rear and right chambers enter the corresponding removal chambers 12 through the oil port 33 and the oil inlet 14 respectively. The quantitative adding mechanism is used to transport the grease to be processed to the leftmost chamber, and the grease in the left chamber enters the removal chamber 12 on the left through the oil port 33 and the oil inlet 14. That is, grease is input into the removal chambers 12 on the left and right sides and the rear side, and the impurities therein are adsorbed by the adsorbent 19. The grease after adsorbing the impurities falls to the bottom of the removal chamber 12, and at this time the sealing plate 2 closes the oil outlet 13, and the grease cannot be discharged.

[0075] When the transfer cylinder 3 continues to move to the bottom, the oil outlet 13 opens, and the grease enters the left, right and rear chambers, while the front chamber is empty. Then the transfer cylinder 3 continues to rise, and the cycle continues. The plasticizer in the grease can be gradually adsorbed by the adsorbent 19.

[0076] by Figure 5 To illustrate, the position of each compartment at the initial position is as follows Figure 5 As shown in (a), we number each compartment. The fourth compartment is located at the front and is empty. After the transfer cylinder 3 rises to the top, it rotates 90 degrees. Each compartment rotates 90 degrees synchronously, which is Figure 5 In the state shown in (b), at this time, chamber No. 3 moves to the front, and the grease inside it is discharged. The grease in chambers No. 1 and No. 2 respectively enters the removal chamber 12 on the rear and right sides to continue to be removed of plasticizer by the adsorbent 19. The quantitative addition mechanism is used to transport the grease to be processed to the chamber on the far left, and the grease enters the removal chamber 12 on the left. When the transfer cylinder 3 drops to the bottom, it will not rotate, that is, the left, right and rear chambers receive the grease discharged from the oil outlet 13, and the chamber on the front side is empty.

[0077] In this application, the grease to be treated is removed from the plasticizer in the removal chambers 12 on the left, rear, and right sides in turn, and then the grease after three removal processes is discharged from the front side, so that the plasticizer in the grease is gradually adsorbed by the adsorbent 19.

[0078] As a further implementation method of this embodiment, the bottom plate of the removal bin 12 is tilted downward in the direction pointing to the central tube 1, and the bottom of the oil outlet 13 and the top of the sealing plate 2 are consistent with the inclination of the bottom plate of the removal bin 12; the bottom of the oil inlet 14, the oil drain and the oil passage 33 are tilted downward in the direction away from the axis of the central tube 1; the upper surface of the bottom plate of the transfer tube 3 is arched upward.

[0079] In this embodiment, the arrangement here facilitates the flow of grease and reduces grease residue.

[0080] As a further implementation method of this embodiment, the top of the removal bin 12 is open, and a cover plate 110 is slidably connected to the upper part of the inner cavity of the removal bin 12. A handle 111 is fixed to the cover plate 110, and a support rod 112 is fixed to the lower surface of the cover plate 110. A steel mesh box 113 is fixed to the bottom of the support rod 112. The inner side of the steel mesh box 113 is open, and a strap 114 is fixed to the outer wall of the central tube 1 and the inner wall of the removal bin 12. The steel mesh box 113 is placed on the strap 114, and the adsorbent 19 is contained in the steel mesh box 113.

[0081] In this embodiment, if Figure 3 as well as Figure 8-Figure 9 As shown, the adsorbent 19 needs to be replaced after being used for a period of time. The cover 110 and the steel mesh box 113 can be taken out through the handle 111. During this process, since the steel mesh box 113 is tilted, the adsorbent 19 inside it will not leak out. After the steel mesh box 113 is taken out, the adsorbent 19 therein can be poured out and new adsorbent 19 can be loaded, and then the steel mesh box 113 can be placed in the removal bin 12. The installation is completed after the steel mesh box 113 contacts the strap 114.

[0082] As a further implementation method of this embodiment, a U-shaped connecting rod 21 is fixed to the bottom of the sealing plate 2, and a through groove 22 is provided at the bottom of the side plate of the central tube 1. The horizontal part of the connecting rod 21 is slidably connected in the through groove 22. The end of the connecting rod 21 away from the sealing plate 2 is fixed to a support plate 23, and a first spring telescopic rod 24 is evenly fixed to the circumference between the lower surface of the support plate 23 and the base 11.

[0083] In this embodiment, if Figure 3 as well as Figure 10 As shown, when the transfer cylinder 3 descends to the bottom, the support plate 23 is pressed down, the first spring telescopic rod 24 is compressed, and the support plate 23 drives the sealing plate 2 to descend through the connecting rod 21, thereby opening the oil outlet 13.

[0084] When the transfer cylinder 3 rises, the first spring telescopic rod 24 is released, thereby driving the supporting plate 23 and the sealing plate 2 to rise, and the sealing plate 2 closes the oil outlet 13.

[0085] Example 2

[0086] The lifting mechanism includes:

[0087] Electric cylinder 41, an L-shaped frame 411 is fixedly connected to the top of the center tube 1, a support rod 412 is fixedly connected between the left side of the L-shaped frame 411 and the center tube 1, a lifting slot 413 is opened on the right side plate of the L-shaped frame 411, and a lifting rod 414 is fixed in the lifting slot 413. The electric cylinder 41 is fixed to the top plate of the L-shaped frame 411 and is provided with a vertical downward push rod 415;

[0088] The hanging box 42 has lifting seats 421 fixedly connected to the left and right sides of the hanging box 42. The left and right lifting seats 421 are slidably connected to the support rod 412 and the lifting rod 414 respectively. The hanging box 42 is fixedly connected to the bottom of the push rod 415;

[0089] as well as

[0090] The suspension rod 43 is connected to the suspension box 42 , the suspension rod 43 is slidably connected to the top plate of the central tube 1 , and the bottom of the suspension rod 43 is fixedly connected to the central column 31 .

[0091] The difference from Example 1 is that this embodiment discloses the technical features of the lifting mechanism, such as Figure 3 as well as Figure 11 As shown, the electric rod drives the push rod 415 to extend or shorten, thereby the hanging box 42 is raised or lowered, and the hanging box 42 drives the transfer tube 3 to rise or fall through the hanging rod 43.

[0092] As a further implementation method of this embodiment, a PLC controller 441 and a control switch 442 are fixedly connected to the central tube 1. The power interface of the PLC controller 441 is electrically connected to the external power supply 443 through the control switch 442. The signal input end of the PLC controller 441 is electrically connected to the timer 444. The output control end of the PLC controller 441 is electrically connected to the built-in motor of the electric cylinder 41 through the forward and reverse control module 445.

[0093] In this embodiment, if Figure 12 As shown, the time is set by the timer 444 so that the PLC controller 441 has a first working time, a first braking time, a second working time and a second braking time that are performed cyclically.

[0094] During the first working time, the PLC controller 441 controls the built-in motor of the electric cylinder 41 to rotate forward through the forward and reverse control module 445. At this time, the push rod 415 is shortened and the transfer cylinder 3 rises; during the second working time, the PLC controller 441 controls the built-in motor of the electric cylinder 41 to rotate reversely through the forward and reverse control module 445. At this time, the push rod 415 is extended and the transfer cylinder 3 is lowered.

[0095] During the first braking time and the second braking time, the push rod 415 remains stationary.

[0096] The intermittent lifting of the transfer cylinder 3 can be achieved.

[0097] Example 3

[0098] The rotating mechanism includes:

[0099] A rotating shaft 51 is rotatably connected between the front and rear side panels of the hanging box 42 and is located to the right of the hanging rod 43. A worm 511 is fixed to the rotating shaft 51. A disk 512 is fixed to the front and rear ends of the rotating shaft 51. A pawl 513 is evenly hinged on the circumference of the disk 512. A return spring 514 is fixed between the pawl 513 and the disk 512. The hanging rod 43 is rotatably connected to the hanging box 42. A worm wheel 515 is fixed to the hanging rod 43 and engages with the worm 511.

[0100] The gear ring 52 is rotatably connected to the outer walls of the front and rear side panels of the hanging box 42 and is concentrically arranged with the disc 512. The inner ring of the gear ring 52 is provided with ratchet teeth 521;

[0101] The rack 53 is fixed to the inner wall of the vertical plate of the L-shaped frame 411 and corresponds to the position of the gear ring 52 .

[0102] The difference from Example 2 is that this embodiment discloses the technical features of the rotation mechanism, such as Figure 13 As shown, the lifting of the hanging box 42 drives the gear ring 52 to lift and lower, as shown in FIG. Figure 15 As shown, when the hanging box 42 drives the gear ring 52 to rise, the arrows I and II in the figure represent the vertical movement direction and the turning direction of the gear ring 52 respectively.

[0103] That is, when the gear ring 52 rises, the gear ring 52 rotates clockwise under the action of the rack 53. At this time, under the action of the pawl 513, the gear ring 52 drives the disc 512 to rotate, as shown in FIG. Figure 14 As shown, the disc 512 drives the rotating shaft 51 and the worm 511 to rotate, and the worm wheel 515 engaged with the worm 511 rotates, so that the suspension rod 43 drives the transfer cylinder 3 to rotate clockwise.

[0104] On the contrary, the gear ring 52 rotates counterclockwise when it descends. At this time, the gear ring 52 rotates idly and cannot drive the disc 512 to rotate, so that the following can be achieved: the rotating cylinder rotates clockwise when it rises, and the transfer cylinder 3 remains stationary when it descends.

[0105] Moreover, the lead angle of the worm 511 in this application is smaller than the equivalent friction angle between the meshing teeth of the worm wheel 515 and the worm 511, that is, the worm 511 and the worm wheel 515 are self-locking, and the worm 511 cannot drive the worm wheel 515 to rotate, ensuring that when the worm wheel 515 does not rotate, the transfer cylinder 3 will not rotate.

[0106] As a further implementation of this embodiment, the ratio of the number of teeth of the worm wheel 515 to the number of starts of the worm 511 is Z, the number of teeth of the gear ring 52 is N, and the number of teeth of the rack 53 is M, then ZN=4M.

[0107] In this embodiment, in order to make the transfer cylinder 3 rotate 90° clockwise each time, ZN=4M is set.

[0108] In this application, the length of the rack 53 is set to be smaller than the rising or falling stroke of the hanging box 42, that is, before the hanging box 42 descends to the bottom, the gear ring 52 has been disengaged from the rack 53, and before the hanging box 42 rises to the top, the gear ring 52 has been disengaged from the rack 53, that is, all the teeth on the rack 53 can be used to drive the gear ring 52 to rotate.

[0109] That is, the number of turns the gear ring 52 rotates when it rises is M / N, the number of turns the worm 511 rotates is M / N, and the number of turns the worm wheel 515 and the transfer cylinder 3 rotate is (M / N) / Z. Since ZN=4M, (M / N) / Z=1 / 4, that is, the transfer cylinder 3 rotates 90°.

[0110] Example 4

[0111] Quantitative addition mechanisms include:

[0112] The transfer bin 61 is fixed to the left side of the top plate of the central tube 1. An oil drop pipe 611 is fixed to the bottom of the transfer bin 61. An annular seat 612 is fixed to the inner wall of the oil drop pipe 611. The cross section of the annular seat 612 is conical. A hanging seat 614 is fixed above the oil drop pipe 611 via a fixing rod 613. A sealing seat 616 is fixed below the hanging seat 614 via a second spring telescopic rod 615. A vertically upward ejector rod 617 is fixed to each chamber of the transfer tube 3.

[0113] The oil storage cylinder 62 is fixed to the rear side of the top plate of the L-shaped frame 411. A filling pipe 621 is provided on the right side of the oil storage cylinder 62, and a valve 622 is fixed to the filling pipe 621;

[0114] The pump barrel 63 is fixed in the top plate of the L-shaped frame 411. The top of the pump barrel 63 is fixed with a delivery pipe 631 and a suction pipe 632. The delivery pipe 631 and the suction pipe 632 are respectively fixed with a first one-way valve 633 and a second one-way valve 634. The first one-way valve 633 allows the fluid to pass through in the direction away from the inner cavity of the pump barrel 63, and the second one-way valve 634 allows the fluid to pass through in the direction of the inner cavity of the pump barrel 63. The head of the delivery pipe 631 is connected to the transfer bin 61, and the head of the suction pipe 632 extends into the oil storage barrel 62. A piston 635 is slidably connected to the pump barrel 63, and the bottom of the piston 635 is fixed with a synchronization rod 636. The bottom of the synchronization rod 636 is fixedly connected to the lifting seat 421 on the left.

[0115] The difference from Example 3 is that this embodiment discloses the technical features of the quantitative addition mechanism, such as Figure 3 and Figure 19 As shown, when the hanging box 42 is raised or lowered, the lifting seat 421 on the left side drives the piston 635 to rise or fall through the synchronous rod 636, as shown in FIG. Figure 2 as well as Figure 18-19As shown, when the piston 635 descends, grease is extracted from the oil storage cylinder 62 through the suction pipe 632 and the second one-way valve 634. When the piston 635 rises, the grease in the pump cylinder 63 enters the transfer bin 61 through the delivery pipe 631 and the first one-way valve 633.

[0116] like Figure 16 As shown, when the transfer cylinder 3 has not moved to the top, under the action of the second spring telescopic rod 615, the sealing seat 616 closes the annular seat 612.

[0117] When the transfer cylinder 3 rises, since the length of the rack 53 is set to be smaller than the rising or falling stroke of the hanging box 42, that is, the transfer cylinder 3 has completed a 90° rotation before rising to the top, the left push rod 617 rotates against the sealing seat 616, as shown Figure 17 As shown, when the transfer cylinder 3 continues to rise, the sealing seat 616 will be lifted up, so that the grease in the transfer bin 61 enters the chamber on the left through the oil drop pipe 611.

[0118] The valve 622 is opened to add the grease to be processed into the oil storage cylinder 62 through the adding pipe 621 .
