Description

Technical Field

[0001] This invention relates to the field of waste resource recycling technology, and more specifically, to an integrated treatment device for waste oil drums and the waste oil inside the drums, and a method for using the same. Background Technology

[0002] In industrial production, transportation, and daily life, a large number of metal oil drums containing waste oil (such as waste engine oil, waste lubricating oil, waste industrial oil, etc.) are generated. These waste oil drums and the waste oil inside them are recyclable waste resources. Their standardized recycling and reuse are of great significance for saving resources and protecting the environment.

[0003] Currently, the industry still uses a traditional segmented manual operation mode for the recycling and processing of waste oil drums and the waste oil inside them. Specifically, the traditional recycling and processing process requires multiple independent steps. First, operators need to manually place the waste oil drums on a vertical drum capping machine and control the machine to cut off the lids. Then, operators need to manually fix the open waste oil drums on a drum unloading cart and manually control the unloading cart to tilt the drums, allowing the waste oil inside to slowly pour into the collection tank to complete the collection. In this process, the manual transfer of waste oil drums is labor-intensive, time-consuming, and requires frequent manual transfer and operation between each step, making it impossible to achieve integrated and continuous operation. The recycling efficiency of waste oil drums and the waste oil inside them is low, making it difficult to adapt to the recycling and processing scenarios of large quantities of waste oil drums. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects in the prior art and provide an integrated treatment device and method for waste oil drums and waste oil inside the drums that can realize integrated and continuous operation of drum lid removal, waste oil dumping and recycling.

[0005] To achieve the above objectives, the technical solution of the present invention is to provide an integrated treatment device for waste oil drums and waste oil inside the drums, comprising: A pallet conveyor line includes a frame, on which a first lifting platform, a second lifting platform, and a pallet are provided. The first lifting platform is located at the capping station of the pallet conveyor line, and a rotary table is provided at the output end of the top of the first lifting platform. A cap-cutting mechanism, located at the cap-cutting station, is used to cut off the caps of the oil drums on the tray; The oil unloading mechanism includes a mechanical gripper and a collection trough. The cap-cutting mechanism and the mechanical gripper are arranged sequentially along the conveying direction of the pallet conveyor line. The mechanical gripper is located at the oil unloading station of the pallet conveyor line, and the collection trough is located on the side of the mechanical gripper away from the pallet conveyor line.

[0006] Preferably, a hot drying chamber is provided between the capping mechanism and the oil unloading mechanism. The hot drying chamber has an aisle through which the pallet conveyor line passes.

The mounting plate is connected to the drive end of the drive assembly. The first needle is fixedly mounted on the mounting plate and has several first air nozzles. The airflow direction of the first air nozzles is inclined upwards along a direction away from the centerline of the first needle. This design allows the high-pressure airflow from the first air nozzles to dislodge the residual oil adhering to the inner wall of the oil drum.

With this design, the drive assembly can drive the first piercing needle to pierce the bottom of the oil drum or return it to its original position.

[0009] Preferably, the first needle includes a shaft and a head. The head is rotatably connected to the bottom end of the shaft. The head has several L-shaped jet channels arranged in a circumferential array around the center line of the head. The jet channels form the first jet port on the outer wall of the head. The shaft has a first flow channel extending into the head and communicating with the jet channels. This design allows the head to rotate while expelling high-pressure airflow, and the high-pressure airflow can cover all areas of the inner wall of the oil drum.

[0010] Preferably, the residual oil removal mechanism further includes a plurality of second needles mounted on the inner ring of the mounting plate. These second needles are arranged in a circumferential array around the first needle. Each second needle has a second flow channel and a second jet nozzle. The second jet nozzle communicates with the second flow channel, and the jet direction of the second jet nozzle extends radially outward along the mounting plate. This design improves the efficiency of removing residual oil adhering to the inner wall of the oil drum.

[0011] Preferably, the residual material removal mechanism further includes a plurality of third needles mounted on the outer ring of the mounting plate. These third needles are arranged in a circumferential array around the first needle. Each third needle has a third flow channel, a third jet nozzle, and a fourth jet nozzle. Both the third and fourth jet nozzles are connected to the third flow channel. The third jet nozzle is located above the fourth jet nozzle, and the jet direction of the third jet nozzle extends radially outward along the mounting plate. The jet direction of the fourth jet nozzle is inclined downward away from the first needle. This design helps to further improve the removal efficiency of residual oil adhering to the inner wall of the oil drum.

[0012] Preferably, the mounting plate has a groove at its bottom, and an adjusting block that slides vertically within the groove is provided. The top of the mounting plate has a threaded groove communicating with the groove, and a screw is threadedly connected to the groove.

This design allows the waste material handling mechanism to adapt to oil drums of different sizes.

[0013] Preferably, the integrated treatment device for the waste oil drum and the waste oil inside the drum further includes an empty drum flattener, which is located on the side of the mechanical gripper away from the hot drying chamber. This design facilitates the recycling of the oil drum.

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed to enable those skilled in the art to better understand and implement the subject matter described herein. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0019] To better understand this invention, the following is combined with... Figures 1-18 The present invention provides a detailed description of an integrated treatment device for a waste oil drum and the waste oil inside the drum, as well as its method of use.

[0020] Example 1: like Figures 1-7 As shown, an integrated treatment device for waste oil drums and the waste oil inside the drums includes: The pallet conveyor line 1 includes a frame 11, on which a first lifting platform 12, a second lifting platform 13 and a pallet 14 are provided. The first lifting platform 12 is located at the capping station of the pallet conveyor line 1, and a rotary table 15 is provided at the output end of the top of the first lifting platform 12. The cap-cutting mechanism 2 is located at the cap-cutting station and is used to cut off the caps of the oil drums 7 on the tray 14. The oil unloading mechanism 3 includes a mechanical gripper 31 and a collection tank 32. The cap cutting mechanism 2 and the mechanical gripper 31 are arranged sequentially along the conveying direction of the pallet conveyor line 1. The mechanical gripper 31 is located at the oil unloading station of the pallet conveyor line 1, and the collection tank 32 is located on the side of the mechanical gripper 31 away from the pallet conveyor line 1.

[0021] It should be noted that a conveyor chain is installed on the frame 11. The conveyor chain is used to drive the pallet 14 to move along the length of the frame 11. The pallet 14 is used to carry the oil drum 7. The rotary table 15 is fixedly installed at the output end of the top of the first lifting platform 12. The pallet 14 and the conveyor chain can be relatively separated or attached. Specifically, when the output end of the first lifting platform 12 extends, it drives the rotary table 15 to move upward, and the rotary table 15 lifts the pallet 14, thereby separating the pallet 14 above the rotary table 15 from the conveyor chain. Alternatively, when the output end of the second lifting platform 13 extends, it directly lifts the pallet 14, thereby separating the pallet 14 above the second lifting platform 13 from the conveyor chain. When the first lifting platform 12 or the second lifting platform 13 returns to its original position, the rotary table 15 or the second lifting platform 13 is separated from the pallet 14, the pallet 14 is in contact with the conveyor chain, and the conveyor chain transports the oil drum 7 on the pallet 14 by driving the pallet 14 to move. When the pallet 14 carries the oil drum 7 to the capping station, the first lifting platform 12 lifts the oil drum 7 through the rotating platform 15, and the capping mechanism 2 performs capping operation on the oil drum 7. During this process, the rotating platform 15 drives the pallet 14 and the oil drum 7 to rotate, cooperating with the capping mechanism 2 to perform capping operation. After the cap is cut off, the first lifting platform 12 is reset, and the pallet conveyor line 1 moves the pallet 14 and the capped oil drum 7 to the unloading station. The second lifting platform 13 lifts the pallet 14 and oil drum 7 at the unloading station, and the mechanical gripper 31 picks up the oil drum 7 at the unloading station and transfers it above the collection tank 32. Then, the mechanical gripper 31 controls the oil drum 7 to flip, preferably by 180°, so that the bottom of the oil drum 7 faces up and the opening after the cap is cut off faces down, so that the waste oil in the oil drum 7 is poured into the collection tank 32 for collection and recycling. The cap-cutting mechanism 2 is set as a vertical oil drum cap-cutting machine. The vertical oil drum cap-cutting machine is existing technology, and its specific structure will not be described in detail. During the cap-cutting process, the roller 21 of the vertical oil drum cap-cutting machine contacts the drum cap, and the drive wheel 22 is in contact with the outer wall of the oil drum 7. The drive wheel 22 and the roller 21 rotate together to cut the drum cap. While the drive wheel 22 is rotating, it will drive the oil drum 7 to rotate around its own center line. The rotary table 15, together with the drive wheel 22, drives the oil drum 7 to rotate, ensuring that the position of the oil drum 7 on the tray 14 will not change due to the cutting, thereby ensuring that the mechanical gripper 31 can accurately grab the oil drum 7 after the cap is cut. The cap-cutting principle of cap-cutting mechanism 2 can be found at the following link: https: / / www.douyin.com / video / 7308232323789638949.

[0022] The mechanical gripper 31 can be a combination of a six-axis robot and a gripper. Both the six-axis robot and the gripper are existing technologies and will not be described in detail here. For example, the gripper can be a suction cup gripper in the oil drum 7 handling robot disclosed in Chinese Patent No. CN213136787U.

[0023] In this embodiment, the rotating table 15 is driven by the motor 16. Specifically, the fixed end of the motor 16 is fixedly connected to the output end of the top of the first lifting platform 12, and the output end of the motor 16 is fixedly connected to the rotating table 15. The bottom of the tray 14 is provided with a slot 141 that engages with the rotating table 15, thereby ensuring that the rotating table 15 can drive the tray 14 to rotate. After the first lifting platform 12 lifts the rotating table 15, the rotating table 15 enters the slot 141 and lifts the tray 14 until it is separated from the conveyor chain. The motor 16 drives the rotating table 15 to rotate, thereby driving the oil drum 7 to rotate around the center line of the oil drum 7, thereby adapting to the cap-cutting mechanism 2 to perform cap-cutting operations on the oil drum 7.

[0024] By using the integrated treatment device for waste oil drums and waste oil inside the drums according to the present invention, the pallet conveyor line 1 can automatically transport the oil drums 7, thereby automatically completing the cap cutting and oil pouring operations of the oil drums 7 in sequence. No manual transfer is required, saving time and effort, greatly reducing labor costs, and greatly improving the recycling efficiency of waste oil drums 7 and waste oil inside the drums. It can be adapted to the recycling and treatment scenarios of large quantities of waste oil drums 7.

[0025] Example 2: As an optimization of Example 1, such as Figures 1-3 As shown, a hot drying chamber 4 is provided between the capping mechanism 2 and the oil unloading mechanism 3. The hot drying chamber 4 is provided with a passageway 401 through which the pallet conveyor line 1 passes. A heater 41 is provided inside the hot drying chamber 4. A fan 42 is provided on the side of the heater 41 near the pallet conveyor line 1.

[0026] It should be noted that the oil (waste oil) in the oil drum 7 is prone to solidification at room temperature, thus transforming into a solid or semi-solid state. The heater 41 can heat the air in the hot drying chamber 4, and the blower 42 blows air towards the oil drum 7 on the tray conveyor line 1, thereby heating the oil in the drum and melting the solid or semi-solid oil into a liquid state, improving the fluidity of the waste oil, so as to facilitate the pouring out of the waste oil and improve the waste oil recovery rate.

[0027] In this embodiment, the heater 41 is configured as a finned steam heat exchanger. The fins can improve the heat dissipation efficiency of the water vapor in the steam heat exchanger, thereby improving the heating efficiency of the steam heat exchanger to the internal space of the hot drying chamber 4. The fan 42 is configured as an axial flow fan 42, thereby increasing the hot air flow rate in the hot drying chamber 4 and ensuring that the hot air can be continuously blown to the oil drum 7, which is conducive to improving the melting efficiency of the oil in the oil drum 7. In addition, the exterior of the hot drying chamber 4 is provided with air knife 43 corresponding to the passage 401. The air duct is located above the passage 401. The air knife 43 forms an air curtain by blowing out high-speed airflow. The air curtain can prevent the hot air in the hot drying chamber 4 from flowing out of the passage 401, thereby improving the heat preservation effect of the hot drying chamber 4 and reducing heat waste. The hot drying chamber 4 is also equipped with an inlet 402, and an air knife 43 is also installed above the inlet 402 to reduce heat loss. The barrel lids cut off by the lid cutting mechanism 2 need to be transferred to the lid rack (not shown in the figure). This can be done by an external robotic arm (not shown in the figure). The lid rack can be transferred from the inlet 402 to the hot drying chamber 4 by an unmanned transport vehicle (not shown in the figure), thereby melting and collecting the oil adhering to the inner wall of the lid, further improving the waste oil recovery rate.

[0028] Example 3: As an optimization of Example 2, such as Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 10 As shown, the integrated treatment device for waste oil drums and waste oil inside the drums also includes a residue removal mechanism 5. The residue removal mechanism 5 includes a drive assembly 51, a mounting plate 52, and a first needle 53. The drive assembly 51 is located on the side of the collection tank 32 away from the mechanical gripper 31. The mounting plate 52 is connected to the drive end of the drive assembly 51. The first needle 53 is fixedly installed on the mounting plate 52. The first needle 53 is provided with a plurality of first air nozzles 5333. The air jet direction of the first air nozzles 5333 is inclined upward along the direction away from the center line of the first needle 53.

[0029] It should be noted that after the mechanical gripper 31 controls the oil drum 7 to be inverted and pour oil for a period of time, the first needle 53 pierces the bottom of the oil drum 7. The air inlet at the top of the first needle 53 is connected to an external high-pressure air source (not shown in the figure) through the air supply pipe 56. The high-pressure airflow enters the first flow channel 534 and is ejected from the first jet nozzle 5333. The jet direction of the first jet nozzle 5333 is obliquely upward towards the inner wall of the bottom of the drum. The high-pressure airflow ejected from the first jet nozzle 5333 flows radially along the inner wall of the barrel bottom. After reaching the outer edge of the inner wall of the barrel bottom, it is blocked by the inner wall of the barrel 7. The high-pressure airflow will flow downward along the inner wall of the barrel 7, thereby blowing down the waste oil attached to the inner wall of the barrel 7. This allows the waste oil attached to the inner wall of the barrel 7 to gradually flow and eventually drip into the collection tank 32, thereby improving the waste oil recovery rate.

[0030] Example 4: As an optimization of Example 3, such as Figure 8 As shown, the drive assembly 51 includes a mounting bracket 511, a sliding bracket 512, and a first drive member 513. A guide post 514 is fixedly mounted on the mounting bracket 511. The sliding bracket 512 is slidably connected to the guide post 514. The first drive member 513 is fixedly mounted on the mounting bracket 511 and is drivenly connected to the sliding bracket 512. The mounting plate 52 is fixedly mounted on the sliding bracket 512.

[0031] It should be noted that the mounting bracket 511 is located on the side of the collection tank 32 away from the mechanical gripper 31. At least two guide columns 514 are provided, and the length direction of the guide columns 514 is vertical. The first driving component 513 is a hydraulic cylinder. The sliding bracket 512 is fixedly connected to the output end of the first driving component 513. The first driving component 513 drives the sliding bracket 512 and the mounting plate 52 to move up and down by telescopic changes, thereby driving the first piercing needle 53 to pierce the bottom of the inverted oil drum 7 or reset it.

[0032] Example 5: As an optimization of Example 4, such as Figure 11 , Figure 12 , Figure 15 and Figure 16 As shown, the first needle 53 includes a rod 531 and a head 532. The head 532 is rotatably connected to the bottom end of the rod 531. The head 532 is provided with several L-shaped jet channels 533. The jet channels 533 are arranged in a circumferential array around the center line of the head 532. The jet channels 533 form a first jet port 5333 at the port on the outer wall of the head 532. The rod 531 is provided with a first flow channel 534, which extends into the head 532 and communicates with the jet channels 533.

[0033] It should be noted that the rod 531 and the head 532 are coaxially arranged, and the center line of the head 532 is also the center line of the first needle 53. "Several" refers to two or more. The jet channel 533 includes a first channel 5331 and a second channel 5332. One end of the first channel 5331 is connected to the first flow channel 534, and the other end of the first channel 5331 is connected to the second channel 5332. The extension direction of the first channel 5331 is along the radial direction of the head 532, and the extension direction of the second channel 5332 is perpendicular to the extension direction of the first channel 5331. The second channel 5332 is inclined upward along the direction away from the center line of the head 532. The port of the second channel 5332 on the outer wall of the head 532 is the first jet port 5333.

[0034] In this embodiment, there are two jet channels 533. The two first channels 5331 of the two jet channels 533 extend in the same direction. The horizontal components of the two second channels 5332 of the two jet channels 533 extend in parallel. The vertical components of the two second channels 5332 extend in parallel. The jet direction of the jet channel 533 has a horizontal outward component and a vertical upward component. The horizontal components of the jet directions of the two jet channels 533 are opposite and not collinear. Therefore, during the jet process, the head 532 of the first needle 53 will rotate around its own center line due to the reaction force generated by the jet. Thus, during the jet process, the high-pressure airflow can sweep across the inner wall corresponding to the bottom of the barrel without dead angles and spread to the surrounding areas, thereby blowing the waste oil on the inner wall of the bottom of the barrel towards the inner wall of the barrel 7, and finally blowing off the waste oil on the inner wall of the barrel 7. The sweeping of the high-pressure airflow can cover all areas of the inner wall of the barrel 7, which is conducive to further improving the waste oil recovery rate. The bottom of the head 532 is conical to facilitate the first needle 53 to pierce the bottom of the barrel. After the first needle 53 pierces the bottom of the oil barrel 7, the head 532 is completely located inside the barrel cavity of the oil barrel 7 to ensure that the rotation of the head 532 is not obstructed by the oil barrel 7. The head 532 is rotatably connected to the rod 531 through a bearing, thereby reducing the frictional resistance of the rod 531 on the head 532 during the rotation of the head 532. In addition, during the rotation of the head 532, the waste oil dripping and adhering to the head 532 can be shaken off to avoid the waste oil clogging the first jet nozzle 5333.

[0035] Example 6: As an optimization of Example 5, such as Figure 10 , Figure 11 and Figure 13As shown, the material handling mechanism 5 also includes a number of second needles 54 installed on the inner ring of the mounting plate 52. The number of second needles 54 are arranged in a circumferential array around the first needle 53. The second needles 54 are provided with a second flow channel 541 and a second jet port 542. The second jet port 542 is connected to the second flow channel 541. The jet direction of the second jet port 542 extends outward along the radial direction of the mounting plate 52.

[0036] It should be noted that the second jet nozzle 542 is located on the side of the second needle 54 away from the first needle 53. The air inlets at the top of the first needle 53 and the second needle 54 are connected to the branch pipe 561 of the air supply pipe 56. An external high-pressure air source supplies air to the second needle 54. The high-pressure airflow enters the second flow channel 541 and is ejected from the second jet nozzle 542, thereby blowing the waste oil in the inner ring of the inner wall of the barrel bottom to the outer ring of the inner wall of the barrel bottom. The bottom of the second needle 54 is conical. At the same time as the first needle 53 pierces the bottom of the barrel, the second needle 54 also pierces the bottom of the barrel. Most of the second air nozzle 542 (the lower part of the second air nozzle 542) is located inside the barrel cavity of the oil barrel 7, and a small part of the second air nozzle 542 (the upper part of the second air nozzle 542) is buried in the bottom of the barrel. This ensures that the high-pressure airflow ejected from the second air nozzle 542 is directed towards the waste oil on the inner wall of the barrel bottom and blows the waste oil to the outer ring, which is beneficial to improving the removal efficiency of residual oil adhering to the inner wall of the oil barrel 7.

[0037] In this embodiment, the second jet nozzle 542 is configured as a fan-shaped annular structure to increase the area of ​​the high-pressure airflow ejected from the second jet nozzle 542 covering the inner wall of the oil drum 7. The opening of the second jet nozzle 542 is large and only one is provided, so the second jet nozzle 542 will not be blocked.

[0038] Example 7: As an optimization of Example 6, such as Figure 10 , Figure 11 and Figure 14 As shown, in addition to the material handling mechanism 5, there are also several third needles 55 mounted on the outer ring of the mounting plate 52. The several third needles 55 are arranged in a circumferential array around the first needle 53. The third needle 55 is provided with a third flow channel 551, a third jet port 552 and a fourth jet port 553. The third jet port 552 and the fourth jet port 553 are both connected to the third flow channel 551. The third jet port 552 is located above the fourth jet port 553. The jet direction of the third jet port 552 extends outward along the radial direction of the mounting plate 52. The jet direction of the fourth jet port 553 is inclined downward along the direction away from the first needle 53.

[0039] It should be noted that the third jet nozzle 552 and the fourth jet nozzle 553 are both located on the side of the third needle 55 away from the first needle 53. The air inlet at the top of the third needle 55 is connected to the branch pipe 561 of the air supply pipe 56. An external high-pressure air source supplies air to the third needle 55. The high-pressure airflow enters the third flow channel 551 and is ejected from the third jet nozzle 552 and the fourth jet nozzle 553. The high-pressure airflow ejected from the third jet nozzle 552 blows the waste oil on the outer ring of the inner wall of the bottom of the barrel towards the inner wall of the barrel 7. The high-pressure airflow ejected from the fourth jet nozzle 553 blows the waste oil on the inner wall of the barrel 7 downward, thereby causing the waste oil on the inner wall of the barrel 7 to drip into the collection tank 32. The bottom of the third needle 55 is conical. At the same time as the first needle 53 pierces the bottom of the barrel, the third needle 55 also pierces the bottom of the barrel. Most of the third air nozzle 552 (the lower part of the third air nozzle 552) is located inside the barrel cavity of the oil barrel 7, and a small part of the third air nozzle 552 (the upper part of the third air nozzle 552) is buried in the bottom of the barrel. This ensures that the high-pressure airflow ejected from the third air nozzle 552 is directed towards the waste oil on the inner wall of the bottom of the barrel and blows the waste oil toward the peripheral inner wall of the oil barrel 7, which is conducive to further improving the removal efficiency of residual oil adhering to the inner wall of the oil barrel 7.

[0040] In this embodiment, both the third jet port 552 and the fourth jet port 553 are configured as fan-shaped annular structures to increase the area of ​​the high-pressure airflow ejected from the third jet port 552 and the fourth jet port 553 covering the inner wall of the oil drum 7. The openings of the third jet port 552 and the fourth jet port 553 are large and only one is provided, so the third jet port 552 and the fourth jet port 553 will not be blocked.

[0041] Example 8: As an optimization of Example 7, such as Figure 9 , Figure 10 , Figure 13 , Figure 14 , Figure 17 and Figure 18 As shown, the bottom of the mounting plate 52 is provided with a sliding groove 521, and an adjusting block 522 is provided in the sliding groove 521 and is slidably connected to the sliding groove 521. The top of the mounting plate 52 is provided with a threaded groove 523 that communicates with the sliding groove 521. A screw 524 is threadedly connected in the threaded groove 523, and the screw 524 is rotatably connected to the adjusting block 522. A handle 525 is fixedly installed at the end of the screw 524 away from the adjusting block 522.

[0042] It should be noted that there are multiple slides 521, adjusting blocks 522, threaded grooves 523, screws 524 and handles 525, which are arranged in a circumferential array around the center line of the mounting plate 52. The length direction of the adjusting blocks 522 is along the radial direction of the mounting plate 52. By rotating the handle 525, the screw 524 can be rotated, thereby moving the adjusting blocks 522 up and down to adjust the position of the adjusting blocks 522. When the bottom of the oil drum 7 is pierced by the first needle 53, the second needle 54 and the third needle 55, the outer edge of the bottom of the oil drum 7 fits against the adjusting block 522. For oil drums 7 of different sizes and models, by adjusting the size of the adjusting block 522 extending out of the slide groove 521, it can be ensured that the first needle 53, the second needle 54 and the third needle 55 penetrate to a suitable depth, thereby ensuring the purging effect on the waste oil inside the oil drum 7, so that the residual material removal mechanism 5 can be adapted to oil drums 7 of different sizes.

[0043] In this embodiment, multiple sets of limiting plates 526 are fixedly installed on the top of the mounting plate 52. The limiting plates 526 are provided with a first waist hole 5261 and a second waist hole 5262. The first waist hole 5261 and the second waist hole 5262 are arranged sequentially along the direction from the center of the mounting plate 52 to the outer edge of the mounting plate 52. The top outer ring of the second needle 54 is fixedly sleeved with a first slider 543 that is slidably connected to the limiting plate 526. The first slider 543 is locked to the limiting plate 526 by two sets of first bolts and nuts 527, and the first bolt passes through the first waist hole 5261. The top outer ring of the third needle 55 is fixedly sleeved with a second slider 554 that is slidably connected to the limiting plate 526. The second slider 554 is locked to the limiting plate 526 by two sets of second bolts and nuts 528, and the second bolt passes through the second waist hole 5262. By loosening the first bolt nut 527 and the second bolt nut 528, the first slider 543 and the second slider 554 can slide along the length direction of the limiting plate 526, thereby adjusting the position of the first slider 543 and the second slider 554, and then adjusting the position of the second needle 54 and the third needle 55 to fit oil drums 7 of different sizes. By tightening the first bolt nut 527 and the second bolt nut 528, the position of the second needle 54 and the third needle 55 can be fixed.

[0044] It should be emphasized that the limiting plate 526 consists of two parallel vertical plates. The first slider 543 and the second slider 554 are slidably disposed between the two vertical plates. The mounting plate 52 has a first strip hole 5291 and a second strip hole 5292 through it. The length direction of the first strip hole 5291 and the second strip hole 5292 are both along the radial direction of the mounting plate 52 and are located between the two vertical plates of the limiting plate 526. The first strip hole 5291 and the second strip hole 5292 are arranged sequentially along the direction from the center of the mounting plate 52 to the outer edge. The second needle 54 passes through the first strip hole 5291 and is slidably connected to the first strip hole 5291. The third needle 55 passes through the second strip hole 5292 and is slidably connected to the second strip hole 5292. The branch tube 561 is a flexible tube to accommodate the position adjustment of the second needle 54 and the third needle 55.

[0045] Example 9: As an optimization of Example 8, such as Figure 1 and Figure 2 As shown, the integrated treatment device for waste oil drums and waste oil inside the drums also includes an empty drum flattening machine 6, which is located on the side of the mechanical gripper 31 away from the hot drying room 4.

[0046] It should be noted that after the residual material removal mechanism 5 removes the residual oil from the inner wall of the oil drum 7, the drive assembly 51 drives the mounting plate 52, the first needle 53, the second needle 54 and the third needle 55 to reset. The mechanical gripper 31 puts the empty oil drum 7 into the empty drum flattener 6, and the empty drum flattener 6 flattens the empty oil drum 7 to reduce the space occupied by the empty oil drum 7, so as to facilitate the recycling of the oil drum 7.

[0047] Example 10: A method for using an integrated treatment device for waste oil drums and the waste oil inside the drums includes the following steps: S1, The cap-cutting mechanism 2 cuts off the cap of the oil drum 7 at the cap-cutting station; S2, Hot drying room 4 heats the waste oil in oil drum 7; S3. The mechanical gripper 31 grabs the oil drum 7 at the oil unloading station and pours the waste oil in the oil drum 7 into the collection tank 32; S4. The drive assembly 51 drives the first needle 53, the second needle 54 and the third needle 55 to pierce the bottom of the oil drum 7, and the first jet nozzle 5333, the second jet nozzle 542, the third jet nozzle 552 and the fourth jet nozzle 553 spray out high-pressure airflow to sweep the inner wall of the oil drum 7. S5. Mechanical gripper 31 puts oil drum 7 into empty drum flattener 6, and empty drum flattener 6 flattens oil drum 7.

[0048] It should be noted that in S1, when the pallet 14 transports the oil drum 7 to the capping station, the first lifting platform 12 lifts the rotary table 15, the pallet 14 and the oil drum 7. When the capping mechanism 2 performs the capping operation on the oil drum 7, the rotary table 15 cooperates to drive the pallet 14 and the oil drum 7 to rotate. After the capping is completed, the first lifting platform 12 returns to its original position. In S3, when the pallet 14 transports the oil drum 7 to the unloading station, the second lifting platform 13 lifts the pallet 14 and the oil drum 7. The mechanical gripper 31 first grabs the oil drum 7 at the unloading station and transfers the oil drum 7 to the top of the collection tank 32. Then, the mechanical gripper 31 drives the oil drum 7 to rotate 180° to pour out the waste oil in the oil drum 7, and the second lifting platform 13 resets. In S4, as the first needle 53 ejects air through the first nozzle 5333, the head 532 rotates around its own center line.
