[0026] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0027] See also Figures 1 to 5 The embodiment of the utility model provides a filtering and purifying device for base oil preparation, which comprises a frame 1, and a movably connected processing component 2 is arranged inside the frame 1.

A mounting groove 211 is provided at the bottom of the processing cylinder 21, and a placement groove 212 is provided at the top of the processing cylinder 21. Fixedly connected mounting frames 22 are provided on both sides of the interior of the processing cylinder 21. A cleaning convex strip 23 is provided on the outer wall of the mounting frame 22 on one side, and a cleaning scraper strip 24 is provided on the outer wall of the mounting frame 22 on the other side; a filter screen 4 connected by adsorption is provided inside the mounting groove 211 through a magnetic block, and a rotatably connected filter cylinder 3 is provided inside the placement groove 212, and the outer wall of the filter cylinder 3 is abutted against the outer wall of the cleaning scraper strip 24, and the inner wall of the filter hole in the filter cylinder 3 is abutted against the outer wall of the cleaning convex strip 23.

[0029] It should be noted that when the rotating rod 13 can drive the filter cartridge 3 to rotate, its outer wall can abut against the outer wall of the cleaning scraper 24 on one side of the inner side of the installation cartridge, and the cleaning scraper 24 can scrape the outer wall of the filter cartridge 3, so that the filtered base oil can fall more smoothly, reducing the phenomenon of base oil residue on the outer wall of the filter cartridge 3;

[0030] It should also be noted that the cleaning ridges 23 are tough, so when the filter holes in the filter cartridge 3 rotate to a position opposite to the end of the cleaning ridges 23 on the other side of the inner wall of the filter cartridge 3, the end of the tough cleaning ridges 23 will be inserted into the filter holes of the filter cartridge 3. Then, as the filter cartridge 3 continues to rotate, the cleaning ridges 23 will be removed from the filter holes and inserted into subsequent filter holes, thereby ejecting and cleaning the stuck materials in multiple filter holes, reducing the clogging of the filter holes, and allowing the filter cartridge 3 to perform filtering operations stably.

[0031] In the embodiments of the present invention, please refer to Figures 1 to 5A fixedly connected partition 11 is mounted above the treatment cylinder 21 in the frame body 1, a top cover 111 is provided below the partition 11, and a fixedly connected ejector pin 112 is provided at the bottom of the top cover 111, the bottom end of the ejector pin 112 abuts against the top of the filter cylinder 3 and is slidably connected, the bottom of the top cover 111 abuts against the top of the treatment cylinder 21, a filling port is provided inside the top cover 111, and a pressure relief valve is provided inside the top cover 111.

[0032] It should be noted that: through the abutment between the ejector pin 112 and the filter cartridge 3, the filter cartridge 3 can be limited in the vertical direction, so that the filter cartridge 3 can stably rotate inside the processing cartridge 21, and through the setting of the pressure relief valve in the top cover 111, in the later stage of the base oil processing, when the inflation pressure of the booster assembly 5 inside the processing cartridge 21 reaches the set value, automatic pressure relief can be performed.

[0033] In the embodiments of the present invention, please refer to Figures 1 to 5 A booster assembly 5 is provided on the top of the partition 11, and the booster assembly 5 includes a support sheet 51. There are two support sheets 51. A telescopic rod 511 is arranged between the two support sheets 51. A spring 512 is sleeved on the outside of the telescopic rod 511. Both ends of the spring 512 are fixedly connected to the two support sheets 51. The bottom of the lower support sheet 51 is fixedly connected to the top of the partition 11. A boss 52 is provided on the top of the upper support sheet 51. An airbag 53 is arranged between the two support sheets 51. An air guide tube 531 and an air intake tube are inserted into the interior of the airbag 53, and one end of the air guide tube 531 away from the airbag 53 is connected to the interior of the top cover 111.

[0034] It should be noted that: one-way valves are provided on the air guide pipe 531 and the air intake pipe, so that when the airbag 53 is subjected to the squeezing force, one-way exhaust can be carried out into the treatment tube 21 through the air guide pipe 531 to prevent the gas from being discharged from the air intake pipe, and when the airbag 53 is reset by the lifting force of the spring 512, the external gas can be sucked in through the air intake pipe, so that when the airbag 53 is subjected to the cyclic squeezing force when the rotating rod 13 rotates in the later stage, the interior of the treatment tube 21 can be circulated and inflated, thereby increasing the air pressure inside the treatment tube 21, and the base oil in the filter tube 3 can flow downward more smoothly.

[0035] In the embodiments of the present invention, please refer to Figures 1 to 5A slidably connected discharge hopper 6 is provided below the processing cylinder 21 inside the frame 1, a sealing sheet 61 is provided at the bottom of the discharge hopper 6, a support frame 62 is provided inside the discharge hopper 6, a rotatably connected linkage rod 63 is inserted inside the support frame 62, a spiral leaf 64 is provided below the outer wall of the linkage rod 63, and a block 65 is provided at the top of the linkage rod 63, a rotating motor 12 is provided at the inner top of the frame 1, a fixedly connected rotating rod 13 is provided at the output end of the rotating motor 12, an extrusion strip 16 is provided at the outer portion of the rotating rod 13 opposite to the boss 52, a rectangular block 14 is provided below the outer wall of the rotating rod 13, and the outer wall of the rectangular block 14 is abutted against the inner wall of the filter cylinder 3, the outer side of the rotating rod 13 is abutted against the top cover 111 and the inner wall of the filter screen 4 and is rotatably connected, a card slot 15 is provided at the bottom of the rotating rod 13, the inner wall of the card slot 15 is abutted against the outer wall of the card block 65, and the card slot 15 and the card block 65 are both polygonal structures.

[0036] It should be noted that: through the arrangement of the squeezing strip 16, when the rotating rod 13 drives the squeezing strip 16 to rotate, when the outer wall of the squeezing strip 16 abuts against the outer wall of the boss 52, the boss 52 can squeeze the airbag 53 below through the slope structure of the outer wall of the boss 52, so that the airbag 53 can be inflated and pressurized into the processing cylinder 21;

[0037] By using an extrusion block to clamp the rotating rod 13 and the filter cartridge 3, the filter cartridge 3 can be rotated synchronously with the rotating rod 13 during use, which can not only produce a centrifugal effect on the filter cartridge 3 to improve the filtering effect of the internal base oil, but also enable the cleaning scraper 24 and the cleaning convex strip 23 to smoothly face the outer wall of the filter cartridge 3 to scrape and clean the outer wall;

[0038] It should also be noted that: through the arrangement of the polygonal structure slot 15 and the block 65, when the rotating rod 13 rotates, the linkage rod 63 and the spiral blade 64 on its outer wall can be stably driven to rotate, thereby making the base oil in the discharge hopper 6 discharge more smoothly.

[0039] In the embodiments of the present invention, please refer to Figures 1 to 5 A screw rod 7 is provided at the bottom of the partition 11, and the bottom end of the screw rod 7 is fixedly connected to the frame 1. A threaded cylinder 71 is provided on the outside of the screw rod 7 at the corresponding positions of the processing cylinder 21 and the discharge hopper 6. A rotatably connected supporting cylinder 73 is provided on the outside of the threaded cylinder 71. The outer wall of the supporting cylinder 73 is rotatably connected to the inner wall of the corresponding processing cylinder 21 and the discharge hopper 6, and a fixedly connected turntable 72 is provided on the outside of the threaded cylinder 71.

[0040] It should be noted that: by setting a rotating support cylinder 73 between the threaded cylinder 71 and the corresponding processing cylinder 21 and discharge hopper 6, when in use, the support cylinder 73 can support the threaded cylinder 71 while allowing the threaded cylinder 71 to rotate smoothly, so that the processing cylinder 21 and the discharge hopper 6 can be driven to move on the frame 1 by controlling the rotation of the threaded cylinder 71 on the screw rod 7, so that the processing cylinder 21 and the discharge hopper 6 can be separated, which can facilitate the staff to disassemble and clean the internal filter cylinder 3, filter screen 4 and other components later.

[0041] The working principle of the filtering and purifying device for base oil preparation provided by the utility model is as follows;

[0042] When using the device, the staff can first add the base oil to be filtered and purified from the filling port in the top cover 111 into the processing cylinder 21 and then control the rotating motor 12 to rotate;

[0043] At this time, the rotating rod 13 connected to the rotating motor 12 can drive the filter cartridge 3 located inside the processing cartridge 21 to rotate. The centrifugal force generated when the filter cartridge 3 rotates can increase the downward flow effect of the base oil in the filter cartridge 3. While the filter cartridge 3 is rotating, its outer wall can abut against the outer wall of the cleaning scraper strip 24 on one side of the installation cartridge, so that the cleaning scraper strip 24 can scrape the outer wall of the filter cartridge 3, so that the filtered base oil can fall more smoothly, reducing the base oil residue on the outer wall of the filter cartridge 3. When the filter hole in the filter cartridge 3 rotates to the position corresponding to the end of the cleaning convex strip 23 on the other side of the inner wall of the filter cartridge 3, the end of the tough cleaning convex strip 23 will be inserted into the filter hole of the filter cartridge 3. As the filter cartridge 3 continues to rotate, the cleaning convex strip 23 will be removed from the filter hole and inserted into the subsequent filter hole, so that the materials stuck in multiple filter holes can be ejected and cleaned, reducing the clogging of the filter holes, so that the filter cartridge 3 can stably perform the filtering operation;

[0044] While the rotating rod 13 is rotating, the extrusion strip 16 on its outer wall can be driven to rotate. When the rotating extrusion strip 16 moves to the position opposite to the convex block, since the outer wall of the boss 52 is a slope structure, the slope structure can convert the horizontal rotation force of the extrusion strip 16 into a vertical driving force to squeeze the airbag 53 below. At this time, the gas inside the squeezed airbag 53 will flow into the processing tube 21 through the air guide pipe 531, and the inside of the processing tube 21 will be pressurized, so that the base oil inside the processing tube 21 can have a driving force to move downward, further improving the falling flowability of the base oil;

[0045] When the base oil in the treatment cylinder 21 completely flows into the discharge hopper 6, the collecting device can be placed under the discharge hopper 6, and the sealing sheet 61 can be opened. At this time, the rotating rod 13 can drive the linkage rod 63 and the spiral blade 64 on the outer wall to rotate, so that the base oil in the discharge hopper 6 can be discharged outward.

[0046] After the purification of the base oil is completed, when the inside of the device needs to be cleaned and replaced, the turntable 72 can be controlled to rotate. The rotating turntable 72 can drive the internal threaded cylinder 71 to rotate inside the support cylinder 73. At this time, the rotating threaded cylinder 71 will move on the outer wall of the screw rod 7, thereby driving the external discharge hopper 6 and the processing cylinder 21 to move downward in sequence. By controlling the gap between the discharge hopper 6 and the processing cylinder 21, the discharge hopper 6, the processing cylinder 21 and the top cover 111 can be separated, which can facilitate the staff to clean the device later.

[0047] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0048] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
