Description

Technical Field

[0001] This utility model belongs to the field of oil production technology, specifically relating to an oil plasticizer removal device. Background Technology

[0002] Oils and fats are important edible and industrial raw materials, widely used in food processing, cosmetics, pharmaceuticals, lubricants, and other fields. During oil production, due to factors such as the growing environment of the oilseed crops and the production equipment and pipelines, the refined oils usually contain a certain amount of plasticizers, requiring removal. Common removal methods include heating distillation, adsorption treatment, molecular distillation, and the addition of chemical reagents. Adsorption treatment utilizes adsorbent materials such as activated carbon or silica gel to adsorb plasticizers from the oils. This method can be repeated to improve removal efficiency. Patent CN 218853521 U discloses a plasticizer contaminant removal system that uses adsorption treatment to remove plasticizers from oils. However, in this patent, the adsorption tubes in the treatment container operate in parallel, allowing only one adsorption treatment for the same batch of oils. The overall removal effect is not ideal, and when the adsorption capacity of the adsorbent decreases, it is necessary to wait for desorption and regeneration before continuing the removal process, affecting the overall processing efficiency and requiring improvement.

The adsorption box is closed on the left side and open on the right side, and several vertically distributed first partitions are fixedly installed on its left inner wall. The outlet of the discharge pump is fixedly connected to the left side wall of the adsorption box below the lowest first partition, and the inlet of the return pump is fixedly connected to the left side wall of the adsorption box above the highest first partition. A guide rail is fixedly installed on the lower right side of the adsorption box along the left-right direction. An electric slider is slidably mounted on the guide rail. A motor is fixedly mounted on the electric slider. A support base is fixedly connected to the motor output shaft facing upward. Both sides of the support base are detachably connected to... The box is equipped with a lid. Several vertically distributed second partitions are fixed on the side of the lid away from the support base. First adsorption boxes are fixedly connected to the upper and lower ends of the side of the lid away from the support base by pillars. Second adsorption boxes are fixed on the upper and lower sides of the second partitions. The left and right sides of the first and second adsorption boxes are perforated plates and filled with adsorbent. The lid can abut against the right side of the adsorption box and be detachably connected to the adsorption box. At this time, the second partition is inserted between two adjacent first partitions, and there is a gap between the first partition and the lid and a gap between the second partition and the left side wall of the adsorption box. The first adsorption box is inserted between the first partition and the adjacent end wall of the adsorption box, and the second adsorption box is inserted between the adjacent first partition and the second partition.

[0005] Preferably, square mounting slots are provided on both the left and right sides of the support base. A first hydraulic cylinder is fixedly mounted on the top of the support base corresponding to the mounting slot. The piston rod of the first hydraulic cylinder faces downward and can extend into the corresponding mounting slot. A square mounting block is fixed on the side of the box cover near the support base. A fixing blind hole is provided on the top of the mounting block. The mounting block is inserted into the mounting slot on the same side. The piston rod of the first hydraulic cylinder extends into the corresponding mounting slot and is inserted into the fixing blind hole of the corresponding mounting block.

[0006] Preferably, the mounting block is adapted to the corresponding mounting groove, and the piston rod of the first hydraulic cylinder is adapted to the corresponding fixed blind hole.

[0007] Preferably, the upper and lower ends of the box cover are fixedly connected to the side away from the support base, and the two limit plates are provided with limit blind holes on the opposite side. The upper and lower ends of the outer wall of the adsorption box are fixedly provided with second hydraulic cylinders. When the box cover abuts against the right side of the adsorption box, the piston rod of the second hydraulic cylinder can correspond to and be inserted into the limit blind hole on the same side.

[0008] Preferably, the piston rod of the second hydraulic cylinder is adapted to the corresponding limiting blind hole.

[0009] Preferably, sealing gaskets are fixedly provided on the upper right side of the adsorption box, the front and rear sides of the second partition, the front, rear, upper and lower four sides of the first adsorption box, the front and rear sides of the second adsorption box and the side away from the second partition.

[0010] Preferably, the top of the material tank is connected to a feed pipe with a feed valve, and the bottom is connected to a discharge pipe with a discharge valve.

[0011] Preferably, the lower part of one side of the material tank is connected to the inlet of the discharge pump through a discharge pipe with a discharge valve, and the upper part is connected to the outlet of the return pump through a return pipe with a return valve.

[0012] The beneficial effects of this utility model are as follows: When removing plasticizers from oils, the corresponding oil material can be first fed into the material tank, and then the discharge pump and return pump can be started to pump the oil material in the material tank into the adsorption box, and the oil material can be made to flow in a serpentine manner from bottom to top. Thus, the oil material can flow through multiple first adsorption boxes and second adsorption boxes in succession. The adsorbent in multiple series-connected adsorption boxes can achieve multiple adsorption treatments of the oil material. Under the drive of the return pump, the oil passing through the adsorption box can be returned to the material tank, and then continue to flow through the adsorption box again under the drive of the discharge pump. That is, the oil can circulate between the material tank and the adsorption box. With the help of multiple series-connected adsorption boxes, multiple adsorption treatments of the oil material can be achieved, resulting in a better removal effect of plasticizers from the oil and making it more practical.

[0013] When the adsorption capacity of the adsorbent decreases to a certain level, after interrupting the discharge and allowing the oil to completely flow back into the tank, first disconnect the connection between the adsorption box and the cover using the detachable connection. Then, operate the electric slider to move it away from the adsorption box, thus separating the corresponding cover from the adsorption box and moving it away from the adsorption box. Next, operate the motor to rotate the support base 180 degrees, which will rotate the pre-installed cover with the corresponding unused adsorption box on the other side to the side closer to the adsorption box. Then, operate the electric slider again to move it towards the adsorption box until the corresponding cover is abutted and installed in place, thus completing the connection between the cover and the adsorption box, and adsorption treatment can continue. Afterwards, the used cover can be removed from the support base using the detachable connection between the cover and the support base for regeneration or replacement. In this way, when the adsorbent's adsorption capacity is insufficient, the lid of another set of corresponding adsorption boxes with intact adsorption capacity can be quickly switched on. The adsorption and removal operation can be resumed after only a short interruption, without having to wait for a long time for desorption and regeneration. This is more conducive to ensuring overall efficiency and is more convenient and practical. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0024] like Figures 1 to 8As shown, a plasticizer removal device for oils includes a material tank 1 and an adsorption box 2. The lower part of one side of the material tank 1 is connected to the inlet of a discharge pump 3, and the upper part is connected to the outlet of a return pump 4. The adsorption box 2 is closed on the left side and open on the right side, and a plurality of vertically distributed first partitions 5 are fixedly provided on its left inner wall. The outlet of the discharge pump 3 is fixedly connected to the left side wall of the adsorption box 2 below the lowermost first partition 5, and the inlet of the return pump 4 is fixedly connected to the left side wall of the adsorption box 2 above the uppermost first partition 5. A guide rail 6 is fixedly installed on the lower right side of the adsorption box 2 along the left-right direction. An electric slider 7 is slidably installed on the guide rail 6. A motor 8 is fixedly installed on the electric slider 7. A support base 9 is fixedly connected to the output shaft of the motor 8 facing upward. A box cover 10 is detachably connected to both the left and right sides of the support base 9. Several vertically distributed second partitions 11 are fixedly installed on the side of the box cover 10 away from the support base 9. A first adsorption box 13 is fixedly connected to the upper and lower ends of the side of the box cover 10 away from the support base 9 through a support column 12. A second adsorption box 14 is fixedly installed on both the upper and lower sides of the second partition 11. The left and right sides of the first adsorption box 13 and the second adsorption box 14 are both perforated plates 15, and the inside is filled with adsorbent 16. The lid 10 can abut against the right side of the adsorption box 2 and be detachably connected to the adsorption box 2. At this time, the second partition 11 is inserted between two adjacent first partitions 5 and there is a gap between the first partition 5 and the lid 10, and there is a gap between the second partition 11 and the left side wall of the adsorption box 2. The first adsorption box 13 is inserted between the first partition 5 and the adjacent end wall of the adsorption box 2, and the second adsorption box 14 is inserted between the adjacent first partition 5 and the second partition 11.

[0025] When removing plasticizers from oils, the corresponding oil material can first be fed into the material tank 1. Then, the discharge pump 3 and the return pump 4 are started to pump the oil material in the material tank 1 into the adsorption box 2. The oil material flows from bottom to top in a serpentine manner, allowing it to flow through multiple first adsorption boxes 13 and second adsorption boxes 14. The adsorbent 16 in the multiple series-connected adsorption boxes can be used to achieve multiple adsorption treatments of the oil material. Under the drive of the return pump 4, the oil passing through the adsorption box 2 can be returned to the material tank 1 and then continue to flow through the adsorption box 2 under the drive of the discharge pump 3. That is, the oil can circulate between the material tank 1 and the adsorption box 2. With the help of multiple series-connected adsorption boxes, multiple adsorption treatments of the oil material can be achieved, resulting in a better removal effect of plasticizers from the oil and making it more practical.

[0026] When the adsorption capacity of the adsorbent decreases to a certain level, after interrupting the discharge and allowing the oil to completely flow back to tank 1, first disconnect the connection between the cover 10 and the adsorption box 2 via the detachable connection between the adsorption box 2 and the cover 10. Then, operate the electric slider 7 to move it away from the adsorption box 2, thus separating the corresponding cover 10 from the adsorption box 2 and moving it away from the adsorption box 2. Next, operate the motor 8 to rotate the support base 9 180 degrees, thus rotating the cover with the corresponding unused adsorption box pre-installed on the other side to the side closer to the adsorption box 2. Then, operate the electric slider 7 again to move it towards the adsorption box 2 until the corresponding cover 10 is abutted and installed in place, thus completing the connection between the corresponding cover 10 and the adsorption box 2, and adsorption treatment can continue. Afterwards, the used cover 10 can be removed from the support base 9 using the detachable connection between the cover 10 and the support base 9 for regeneration or replacement. In this way, when the adsorbent's adsorption capacity is insufficient, the lid 10 of another set of corresponding adsorption boxes with intact adsorption capacity can be quickly switched on. Adsorption and removal operations can resume after only a short interruption, without waiting for a long time for desorption and regeneration, which is more conducive to ensuring overall efficiency and is more convenient and practical. The perforated plates 15 on the left and right sides of the first adsorption box 13 and the second adsorption box 14 are designed for oil circulation. The adsorbent 16 inside can use existing conventional adsorption materials such as activated carbon, silica gel, and biochar. The motor 8 can be a conventional stepper motor with a brake function to achieve the corresponding angle of rotation and position locking after rotation.

[0027] In this embodiment, square mounting slots 17 are provided on both the left and right sides of the support base 9. A first hydraulic cylinder 18 is fixedly mounted on the top of the support base 9 corresponding to the mounting slot 17. The piston rod of the first hydraulic cylinder 18 faces downward and can extend into the corresponding mounting slot 17. A square mounting block 19 is fixedly mounted on the side of the cover 10 near the support base 9. A fixing blind hole 20 is provided on the top of the mounting block 19. The mounting block 19 is inserted into the mounting slot 17 on the same side. The piston rod of the first hydraulic cylinder 18 extends into the corresponding mounting slot 17 and is inserted into the fixing blind hole 20 of the corresponding mounting block 19. When installing the cover 10 on the support base 9, the mounting block 19 on the cover 10 can be first inserted into the corresponding mounting groove 17 to position and install the cover 10. Then, the corresponding first hydraulic cylinder 18 is operated, causing its piston rod to extend and insert into the corresponding fixing blind hole 20 to fix the mounting block 19 in place, thus further fixing the cover 10 and facilitating the switching of the cover 10. When removing the cover 10 from the support base 9, simply operate the corresponding first hydraulic cylinder 18 to retract and reset its piston rod, releasing the insertion and fixing of the mounting block 19. Then, pull the mounting block 19 out of the corresponding mounting groove 17 to remove the cover 10 from the support base 9, so that the adsorbent 16 in the corresponding adsorption box on the cover 10 can be desorbed, regenerated, or replaced.

[0028] In this embodiment, the mounting block 19 is adapted to the corresponding mounting groove 17, and the piston rod of the first hydraulic cylinder 18 is adapted to the corresponding fixing blind hole 20 to ensure the smooth fixing and installation of the box cover 10.

[0029] In this embodiment, the upper and lower ends of the cover 10 are fixedly connected to the side away from the support base 9 by limiting plates 21. Limiting blind holes 22 are opened on the opposite side of the two limiting plates 21. The upper and lower ends of the outer wall of the adsorption box 2 are fixedly provided with second hydraulic cylinders 23. When the cover 10 abuts against the right side of the adsorption box 2, the piston rod of the second hydraulic cylinder 23 can be aligned with the limiting blind hole 22 on the same side and inserted into it. This allows the piston rod of the second hydraulic cylinder 23 to be aligned with the limiting blind hole 22 on the same side when the cover 10 abuts against the right side of the adsorption box 2. Then, the second hydraulic cylinder 23 is operated to extend its piston rod and insert it into the corresponding limiting blind hole 22, thereby fixing the cover 10 in place and ensuring the stability of the connection between the cover 10 and the adsorption box 2, without affecting the subsequent flow and adsorption of grease. When it is necessary to switch the cover 10, simply run the second hydraulic cylinder 23 first to retract and reset its piston rod, which will release the locking of the cover 10. Then, perform the switching operation as described above.

[0030] In this embodiment, the piston rod of the second hydraulic cylinder 23 is adapted to the corresponding limiting blind hole 22 to ensure the smooth insertion and fixation of the box cover 10.

[0031] In this embodiment, sealing gaskets 24 are fixedly provided on the upper right side of the adsorption box 2, the front and rear sides of the second partition 11, the front, rear, upper and lower four sides of the first adsorption box 13, the front and rear sides of the second adsorption box 14 and the side away from the second partition 11, so as to ensure the sealing of each place, so that the grease can flow smoothly and avoid oil leakage.

[0032] In this embodiment, the top of the material tank 1 is connected to a feed pipe 26 with a feed valve 25, and the bottom is connected to a discharge pipe 28 with a discharge valve 27, which are used for feeding before removal and discharging after removal, respectively.

[0033] In this embodiment, the lower part of one side of the material tank 1 is connected to the inlet of the discharge pump 3 through the discharge pipe 30 with the discharge valve 29, and the upper part is connected to the outlet of the return pump 4 through the return pipe 32 with the return valve 31, so as to better control the progress and stop of the cyclic adsorption and removal operation.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
