Detailed Implementation

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] like Figure 1-19 As shown, the present invention has the following four specific embodiments. Example 1

[0060] A device for removing plasticizers from grease includes a central cylinder 1, a base 11 fixedly connected to the bottom of the central cylinder 1, and removal chambers 12 fixedly connected to the left, right, and rear sides of the central cylinder 1. An oil outlet 13 and an oil inlet 14 are respectively opened on the central cylinder 1 at the bottom and top of the removal chambers 12. An oil discharge port 15 is opened on the front side of the central cylinder 1 at the same height as the oil inlet 14. An oil discharge chamber 16 is fixedly connected to the oil discharge port 15. An oil discharge pipe 17 is fixedly connected to the oil discharge chamber 16. A collection box 18 is placed on the base 11. The head of the oil discharge pipe 17 extends into the collection box 18. An adsorbent 19 is provided in the removal chamber 12.

[0061] The grease and plasticizer removal device also includes:

[0062] Sealing plate 2 is slidably connected to the outer wall of the central cylinder 1 and corresponds to the position of the oil outlet 13;

[0063] The transfer cylinder 3 is slidably connected in the central cylinder 1. The outer diameter of the transfer cylinder 3 is the same as the inner diameter of the central cylinder 1. A central column 31 is fixedly connected to the center of the transfer cylinder 3. A partition 32 is fixedly connected between the central column 31 and the inner wall of the transfer cylinder 3. The partition 32 divides the transfer cylinder 3 into four compartments. An oil outlet 33 is opened at the bottom of the side plate of the transfer cylinder 3 corresponding to the position of each compartment.

[0064] The lifting mechanism is used to drive the transfer cylinder 3 to lift intermittently. When the transfer cylinder 3 is at the bottom, the side plate of the transfer cylinder 3 is 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 outlet 33 is at the same height as the oil inlet 14 and the oil outlet 15, and the sealing plate 2 closes the oil outlet 13.

[0065] The rotating mechanism is used to drive the transfer cylinder 3 to rotate 90° clockwise during the upward process of the transfer cylinder 3.

[0066] And a metering addition mechanism, when the transfer cylinder 3 is at the top, the metering addition mechanism is used to deliver the grease to be processed to the leftmost compartment.

[0067] In this embodiment, as Figures 1-5 As shown, during the operation of this device, in the initial state, the transfer cylinder 3 is located at the bottom (i.e., Figure 3 (as shown in the diagram) At this time, 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 left and right sides and the rear side chambers through the oil outlet 13, while the front side chamber is empty.

[0068] 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 (As shown in the diagram), the empty compartment at the front moves to the left, while the compartment at the right moves to the front, as... Figure 6 As shown, the grease in the right compartment enters the oil discharge chamber 16 through the oil inlet 33 and the oil outlet 15, and then enters the collection box 18 through the oil discharge pipe 17.

[0069] When the transfer cylinder 3 rises, it will rotate. When the oil outlet 33 moves to the same height as the oil outlet 13, the transfer cylinder 3 has already rotated by the angle of movement. That is, at this time, the positions of the oil outlet 33 and the oil outlet 13 are offset. The outer diameter of the transfer cylinder 3 is consistent with the inner diameter of the central cylinder 1, which ensures that the grease in each compartment will not leak out from the oil outlet 33 when the transfer cylinder 3 rises and falls.

[0070] When the transfer cylinder 3 moves to the top, the grease in the front chamber is discharged, while the grease in the rear and right chambers enters the corresponding removal chambers 12 through the oil port 33 and the oil inlet 14 respectively. The quantitative addition mechanism is used to transport the grease to be treated to the leftmost chamber. The grease in the left chamber enters the left removal chamber 12 through the oil port 33 and the oil inlet 14. That is, there is grease input in the removal chambers 12 on the left, right and rear sides, and the impurities in it are adsorbed by the adsorbent 19. The grease after adsorbing the impurities falls to the bottom of the removal chamber 12. At this time, the sealing plate 2 closes the oil outlet 13, and the grease cannot be discharged.

[0071] 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 compartments, leaving the front compartment empty. Then the transfer cylinder 3 continues to rise, and this cycle repeats, so that the plasticizer in the grease can be gradually adsorbed by the adsorbent 19.

[0072] by Figure 5 The initial positions of each compartment are as follows: Figure 5 As shown in (a), we number the compartments. Compartment number four is located at the front and is empty. After the transfer cylinder 3 rises to the top, it rotates 90°. All compartments rotate 90° synchronously. Figure 5 In the state shown in (b), the No. 3 chamber moves to the front and the grease inside is discharged. The grease in the No. 1 and No. 2 chambers enter the rear and right removal chambers 12 respectively to continue to be removed by the adsorbent 19 to remove plasticizer. The quantitative addition mechanism is used to transport the grease to be treated to the leftmost chamber and the grease enters the left removal chamber 12. When the transfer cylinder 3 descends 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 front chamber is empty.

[0073] In this application, the grease to be treated is subjected to plasticizer removal in the removal chambers 12 on the left, rear and right sides in sequence. Then, the grease after the three removal processes is discharged from the front side, thereby gradually adsorbing the plasticizer in the grease by the adsorbent 19.

[0074] As a further embodiment of this example, the bottom plate of the removal chamber 12 is inclined downward in the direction pointing towards the central cylinder 1, and the bottom of the oil outlet 13 and the top of the sealing plate 2 are inclined at the same degree as the bottom plate of the removal chamber 12; the bottom of the oil inlet 14, the oil outlet 15 and the oil passage 33 are inclined downward in the direction away from the axis of the central cylinder 1; the upper surface of the bottom plate of the transfer cylinder 3 is arched upward.

[0075] In this embodiment, this arrangement facilitates the flow of grease and reduces grease residue.

[0076] As a further embodiment of this example, the top of the removal chamber 12 is open, and a cover plate 110 is slidably connected to the upper part of the inner cavity of the removal chamber 12. A handle 111 is fixedly connected to the cover plate 110, and a support rod 112 is fixedly connected to the lower surface of the cover plate 110. A steel mesh box 113 is fixedly connected to the bottom of the support rod 112. The inner side of the steel mesh box 113 is open, and a ramp 114 is fixedly connected to the outer wall of the central cylinder 1 and the inner wall of the removal chamber 12. The steel mesh box 113 is placed on the ramp 114, and the adsorbent 19 is contained in the steel mesh box 113.

[0077] In this embodiment, such as Figure 3 as well as Figures 8-9As shown, the adsorbent 19 needs to be replaced after a period of use. The cover plate 110 and the steel mesh box 113 can be removed by the handle 111. During this process, the adsorbent 19 inside the steel mesh box 113 will not leak out because the steel mesh box 113 is tilted. After the steel mesh box 113 is removed, the adsorbent 19 inside can be poured out and new adsorbent 19 can be installed. Then the steel mesh box 113 is placed in the removal chamber 12. The installation is completed after the steel mesh box 113 comes into contact with the mounting plate 114.

[0078] As a further embodiment of this example, a U-shaped connecting rod 21 is fixedly connected to the bottom of the sealing plate 2, and a through groove 22 is opened at the bottom of the side plate of the central cylinder 1. The horizontal part of the connecting rod 21 is slidably connected in the through groove 22. A support plate 23 is fixedly connected to the end of the connecting rod 21 away from the sealing plate 2. A first spring telescopic rod 24 is uniformly fixedly connected to the lower surface of the support plate 23 and the base 11.

[0079] In this embodiment, such as Figure 3 as well as Figure 10 As shown, when the transfer cylinder 3 descends to the bottom, it will press down the support plate 23, compress the first spring telescopic rod 24, and the support plate 23 will drive the sealing plate 2 to descend through the connecting rod 21, thereby opening the oil outlet 13.

[0080] When the transfer cylinder 3 rises, the first spring telescopic rod 24 is released, thereby driving the support plate 23 and the sealing plate 2 to rise, and the sealing plate 2 closes the oil outlet 13. Example 2

[0081] The lifting mechanism includes:

[0082] The electric cylinder 41 has an L-shaped frame 411 fixed to the top of the central cylinder 1. A support rod 412 is fixed between the left side of the L-shaped frame 411 and the central cylinder 1. A lifting groove 413 is opened on the right side plate of the L-shaped frame 411. A lifting rod 414 is fixed in the lifting groove 413. The electric cylinder 41 is fixed to the top plate of the L-shaped frame 411. The electric cylinder 41 has a vertically downward push rod 415.

[0083] The suspended box 42 has lifting seats 421 fixedly connected to its left and right sides. The two lifting seats 421 are slidably connected to the support rod 412 and the lifting rod 414 respectively. The suspended box 42 is fixedly connected to the bottom of the push rod 415.

[0084] And a boom 43, which is connected to the jacking box 42, and is slidably connected to the top plate of the central cylinder 1, and the bottom of the boom 43 is fixedly connected to the central column 31.

[0085] The difference from Embodiment 1 is that this embodiment discloses the technical features of the lifting mechanism, such as... Figure 3 as well as Figure 11As shown, the electric rod drives the push rod 415 to extend or shorten, thereby raising and lowering the hoisting box 42. The hoisting box 42 drives the transfer cylinder 3 to rise and fall through the hoisting rod 43.

[0086] As a further embodiment of this example, a PLC controller 441 and a control switch 442 are fixedly connected to the central cylinder 1. The power interface of the PLC controller 441 is electrically connected to an external power supply 443 through the control switch 442. A timer 444 is electrically connected to the signal input terminal of the PLC controller 441. The output control terminal of the PLC controller 441 is electrically connected to the built-in motor of the electric cylinder 41 through a forward and reverse control module 445.

[0087] In this embodiment, such as 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 carried out in a cycle.

[0088] During the first working period, 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 shortens and the transfer cylinder 3 rises. During the second working period, the PLC controller 441 controls the built-in motor of the electric cylinder 41 to rotate in reverse through the forward and reverse control module 445. At this time, the push rod 415 extends and the transfer cylinder 3 descends.

[0089] During the first braking time and the second braking time, push rod 415 remains stationary.

[0090] This allows for intermittent lifting and lowering of the transfer cylinder 3. Example 3

[0091] The rotating mechanism includes:

[0092] A rotating shaft 51 is rotatably connected between the front and rear side plates of the hoisting box 42 and located on the right side of the hoisting rod 43. A worm gear 511 is fixedly connected to the rotating shaft 51. A disc 512 is fixedly connected to the front and rear ends of the rotating shaft 51. A pawl 513 is evenly hinged around the circumference of the disc 512. A return spring 514 is fixedly connected between the pawl 513 and the disc 512. The hoisting rod 43 is rotatably connected to the hoisting box 42. A worm wheel 515 that meshes with the worm gear 511 is fixedly connected to the hoisting rod 43.

[0093] The toothed ring 52 is rotatably connected to the outer wall of the front and rear side plates of the hoisting box 42 and is concentrically set with the disc 512. The inner ring of the toothed ring 52 has ratchet teeth 521.

[0094] 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 toothed ring 52.

[0095] The difference between this embodiment and Embodiment 2 is that this embodiment discloses the technical features of the rotating mechanism, such as... Figure 13As shown, the lifting of the hoist 42 drives the lifting of the gear ring 52, as follows: Figure 15 As shown, when the hoisting box 42 drives the toothed ring 52 to rise, arrows I and II in the figure represent the vertical movement direction and the turning direction of the toothed ring 52, respectively.

[0096] When the toothed ring 52 rises, it rotates clockwise under the action of the rack 53. At this time, under the action of the pawl 513, the toothed ring 52 drives the disk 512 to rotate. Figure 14 As shown, the disc 512 drives the rotating shaft 51 and the worm gear 511 to rotate, and the worm wheel 515 meshing with the worm gear 511 rotates, thereby the boom 43 drives the transfer cylinder 3 to rotate clockwise.

[0097] Conversely, when the gear ring 52 descends, it rotates counterclockwise. At this time, the gear ring 52 spins idly and cannot drive the disc 512 to rotate, thus achieving the following: when the rotating cylinder rises, it rotates clockwise, and when the transfer cylinder 3 descends, it remains stationary.

[0098] Furthermore, the lead angle of the worm 511 in this application is less 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, thus ensuring that the transfer cylinder 3 will not rotate when the worm wheel 515 does not rotate.

[0099] As a further implementation of this embodiment, the ratio of the number of teeth of the worm gear 515 to the number of teeth of the worm 511 is Z, the number of teeth of the ring gear 52 is N, and the number of teeth of the rack 53 is M, then ZN=4M.

[0100] In this embodiment, ZN=4M is set so that the transfer cylinder 3 rotates 90° clockwise each time.

[0101] In this application, the length of the rack 53 is set to be less than the rising or falling stroke of the hoist 42. That is, before the hoist 42 descends to the bottom, the gear ring 52 has already disengaged from the rack 53, and before the hoist 42 rises to the top, the gear ring 52 has already disengaged from the rack 53. In other words, all the teeth on the rack 53 can be used to drive the gear ring 52 to rotate.

[0102] If the number of rotations of the gear ring 52 when it rises is M / N, then the number of rotations of the worm 511 is M / N, and the number of rotations of the worm wheel 515 and the transfer cylinder 3 is (M / N) / Z. Since ZN=4M, then (M / N) / Z=1 / 4, that is, the transfer cylinder 3 rotates 90°. Example 4

[0103] The quantitative addition mechanism includes:

[0104] The transfer chamber 61 is fixed to the left side of the top plate of the central cylinder 1. The bottom of the transfer chamber 61 is fixed to the oil drop pipe 611. The inner wall of the oil drop pipe 611 is fixed to the annular seat 612. The annular seat 612 has a conical cross section. The top of the oil drop pipe 611 is fixed to the hanging seat 614 through the fixing rod 613. The bottom of the hanging seat 614 is fixed to the sealing seat 616 through the second spring telescopic rod 615. Each compartment of the transfer cylinder 3 is fixed to a vertically upward top rod 617.

[0105] An oil storage tank 62 is fixed to the rear side of the top plate of the L-shaped frame 411. An adding pipe 621 is provided on the right side of the oil storage tank 62, and a valve 622 is fixed to the adding pipe 621.

[0106] Pump cylinder 63 is fixedly connected to the top plate of L-shaped frame 411. A delivery pipe 631 and a suction pipe 632 are fixedly connected to the top of pump cylinder 63. A first one-way valve 633 and a second one-way valve 634 are fixedly connected to the delivery pipe 631 and the suction pipe 632, respectively. The first one-way valve 633 allows fluid to pass in a direction away from the inner cavity of pump cylinder 63, and the second one-way valve 634 allows fluid to pass in a direction towards the inner cavity of pump cylinder 63. The head of delivery pipe 631 is connected to transfer chamber 61, and the head of suction pipe 632 extends into oil storage tank 62. A piston 635 is slidably connected in pump cylinder 63. A synchronizing rod 636 is fixedly connected to the bottom of piston 635. The bottom of synchronizing rod 636 is fixedly connected to the lifting seat 421 on the left side.

[0107] The difference from Example 3 is that this example discloses the technical features of the quantitative addition mechanism, such as... Figure 3 and Figure 19 As shown, when the hoisting box 42 is raised or lowered, the lifting seat 421 on the left side drives the piston 635 to rise or fall via the synchronizing rod 636, as... Figure 2 as well as Figures 18-19 As shown, when piston 635 descends, grease is drawn from oil reservoir 62 through suction pipe 632 and second check valve 634. When piston 635 rises, grease in pump cylinder 63 enters transfer chamber 61 through delivery pipe 631 and first check valve 633.

[0108] like Figure 16 As shown, when the transfer cylinder 3 has not moved to the top, the sealing seat 616 closes the annular seat 612 under the action of the second spring telescopic rod 615.

[0109] When the transfer cylinder 3 rises, because the length of the rack 53 is less than the rising or falling stroke of the hoisting box 42, the transfer cylinder 3 has already completed a 90° rotation before reaching the top. The left-side push rod 617 rotates relative to the sealing seat 616, as shown... Figure 17 As shown, when the transfer cylinder 3 continues to rise, it will lift the sealing seat 616, so that the grease in the transfer chamber 61 enters the left chamber through the oil drop pipe 611.

[0110] By opening valve 622, the grease to be treated can be added to oil reservoir 62 through adding pipe 621.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
