Description

A chemical drum cleaning device Technical Field

[0001] This application relates to the field of chemical equipment cleaning technology, specifically to a chemical drum cleaning device. Background Technology

[0002] Chemical drums are core containers for material storage and transportation in the chemical industry. Their post-use recycling and cleaning are not only crucial for resource recycling but also a key step in meeting environmental compliance requirements. Currently, with increasingly stringent national environmental requirements and the deepening implementation of the "dual carbon" goal, the cleanliness, operational efficiency, and waste liquid recycling rate during chemical drum cleaning have become core demands for optimization within the industry.

[0003] Ultrasonic cleaning technology, with its unique advantage of high-frequency vibration that can remove residual deposits from the inner and outer walls of containers without leaving any blind spots, is particularly suitable for cleaning small-diameter chemical drums (the diameter of which is much smaller than the size of the drum itself). Because of their narrow openings, traditional spraying and brushing methods struggle to reach deep inside these drums. Ultrasonic energy, however, can penetrate to all areas of the drum with the cleaning fluid, theoretically solving the problem of blind spots in the cleaning of small-diameter drums. However, existing ultrasonic cleaning applications are not yet fully adapted to the structural characteristics of small-diameter chemical drums, preventing the full realization of the technology's advantages.

[0004] Referring to Chinese patent document CN210280104U, published on April 10, 2020, entitled "Chemical Drum Cleaning Device," the device includes a circulating track and a frame. The frame is equipped with a drive mechanism and a chemical drum clamp. The drive mechanism can drive the frame to slide along the circulating track and can also drive the chemical drum clamp to perform lifting, rotating, and opening / closing actions. Below the circulating track, there are sequentially arranged a placement platform, a first water tank, a second water tank, a third water tank, a drying mechanism, and a clean chemical drum placement area, wherein an ultrasonic generator is installed in the first water tank.

[0005] Referring to the aforementioned patented technical solution, a chemical drum is held in place by a chemical drum clamp and immersed in a first water tank. An ultrasonic generator is then used to clean the inside of the chemical drum. However, in practical applications, small-diameter chemical drums, due to their narrow openings and large volume, require the opening to face upwards during cleaning to allow the cleaning solution to be poured in. After cleaning, the opening must be turned downwards to drain the waste liquid. This flipping process still requires manual assistance, which is not only costly due to manual intervention but also inconvenient for the continuous transport and cleaning of multiple sets of chemical drums. Summary of the Invention

[0006] In view of this, this application provides a chemical drum cleaning device that realizes automatic continuous immersion cleaning and waste liquid discharge of small-diameter chemical drums, reduces manual intervention, improves cleaning efficiency and cleanliness, and reduces cleaning liquid waste.

[0007] To solve the above-mentioned technical problems, this application provides a chemical drum cleaning device, including an ultrasonic cleaning tank and a rotating support disposed inside the ultrasonic cleaning tank. The two ends of the rotating support are rotatably installed on the left side wall and the right side wall of the ultrasonic cleaning tank, respectively.

[0008] The rotating support includes two T-shaped turntables arranged opposite each other. The rotation axes of the two T-shaped turntables are rotatably connected to the corresponding side walls of the ultrasonic cleaning tank. The T-shaped turntables are evenly provided with multiple mounting slots along the circumference. Four L-shaped limiting strips are fixedly installed between two mounting slots corresponding to each other along the axial direction of the T-shaped turntables. The four L-shaped limiting strips located in the same mounting slot cooperate to form a rectangular frame for radial limiting of the chemical drum.

[0009] The ultrasonic cleaning tank is equipped with a drive assembly, which is connected to a T-shaped turntable for driving the rotating support to rotate, so that the chemical drum is immersed in the ultrasonic cleaning tank for cleaning.

[0010] By adopting the above technical solution, the chemical drum is placed inside a rectangular frame formed by four L-shaped limiting strips. The rectangular frame is fixed by the axially corresponding mounting groove of the T-shaped turntable, which radially limits the chemical drum and prevents it from shifting during movement. When the drive component is working, it drives the T-shaped turntable to rotate, which in turn drives the rotating support to rotate as a whole. The rotating support carries the chemical drum inside the rectangular frame from above the ultrasonic cleaning tank to the inside of the tank, so that the chemical drum is completely immersed in the cleaning solution. The ultrasonic cleaning tank is then activated to clean the inner and outer walls of the chemical drum. After cleaning, the drive component continues to drive the rotating support to rotate, moving the chemical drum out of the cleaning solution and back to above the tank, completing the cleaning process. This achieves automatic conveying and immersion cleaning of the chemical drum, reducing manual intervention and improving cleaning efficiency. At the same time, the radial limiting of the rectangular frame ensures the stability of the chemical drum's position during the cleaning process, ensuring uniform cleaning results.

[0011] Optionally, it also includes a V-shaped manifold, with fixed pipes fixedly installed at both ends of the V-shaped manifold. The rotating shaft has a hollow structure. The fixed pipes pass through the rotating shafts of adjacent T-shaped turntables and are fixedly connected to a fixed base fixedly installed outside the ultrasonic cleaning tank. The opening of the V-shaped manifold faces upward.

[0012] By adopting the above technical solution, the V-shaped manifold passes through the rotating shaft of the T-shaped turntable via fixed pipes at both ends, and is then fixed to the fixed base outside the ultrasonic cleaning tank, so that the V-shaped manifold remains in a fixed position when the rotating support rotates. When the rotating support drives the cleaned chemical drum to rotate above the ultrasonic cleaning tank, the opening of the chemical drum faces downward, and the residual cleaning liquid inside flows out along the opening. The V-shaped manifold with its opening facing upward receives the outflowing cleaning liquid. With the guiding effect of the V-shaped structure, the cleaning liquid is concentrated at the bottom of the manifold and then discharged through the fixed pipe. This achieves effective collection of residual cleaning liquid from the cleaned chemical drum, avoiding the direct discharge of used cleaning liquid from the inside of the chemical drum into the interior of the ultrasonic cleaning tank, which would cause the concentration of impurities in the cleaning liquid to be too high. At the same time, the V-shaped structure improves the efficiency of cleaning liquid flow and reduces cleaning liquid waste.

[0013] Optionally, a filter box is fixedly installed on the outer wall of the ultrasonic cleaning tank. The filter box contains a filter layer. The fixed pipe on the left side is a closed structure, and a conduit is fixedly connected to the right end of the fixed pipe on the right side. The end of the conduit away from the fixed pipe extends into the upper interior of the filter box. A return pipe is fixedly installed at the lower interior of the filter box. The end of the return pipe away from the filter box extends into the upper interior of the ultrasonic cleaning tank. A circulation pump is fixedly installed on the outer wall of the ultrasonic cleaning tank. The circulation pump is connected in series in the return pipe.

[0014] By adopting the above technical solution, the cleaning fluid collected by the V-shaped manifold enters the conduit through the right-side fixed pipe. The conduit transports the cleaning fluid to the upper part of the filter box. The cleaning fluid permeates from top to bottom in the filter box. When passing through the filter layer, the filter layer intercepts impurities in the cleaning fluid. The circulation pump starts, drawing the filtered cleaning fluid from the lower part of the filter box through the return pipe and transporting it back to the upper part of the ultrasonic cleaning tank for reuse in the cleaning operation. The left-side fixed pipe has a closed structure to prevent the cleaning fluid from leaking from the left side, ensuring that all collected cleaning fluid enters the filtration process through the right-side fixed pipe. This achieves the recycling of the cleaning fluid, reduces the cost of cleaning fluid consumption, and removes impurities from the used cleaning fluid inside the chemical drum through the filter layer. This improves the impurity filtration effect while preventing impurities from re-adhering to the surface of the chemical drum and affecting the cleaning effect, thus extending the service life of the cleaning fluid.

[0015] Optionally, a baffle is rotatably mounted on the upper left side wall of the ultrasonic cleaning tank via a rotating shaft. The baffle engages with the mounting groove above the T-shaped turntable on the left side. A connecting rod is fixedly mounted on the front end of the rotating shaft of the baffle. A baffle cylinder is rotatably mounted on the front side of the ultrasonic cleaning tank. The push rod end of the baffle cylinder is rotatably connected to the end of the connecting rod away from the rotating shaft.

[0016] By adopting the above technical solution, during the cleaning process of chemical drums, the push rod of the baffle cylinder is in an extended state, pushing the connecting rod to rotate around the baffle's rotation axis, causing the baffle to rotate to a position that mates with the mounting slot above the left T-shaped turntable, thus blocking the chemical drums within the rectangular frame. When the chemical drums are finished cleaning and need to be unloaded, the push rod of the baffle cylinder retracts, pulling the connecting rod to rotate in the opposite direction, thereby causing the baffle to rotate around the rotation axis, disengaging the baffle from the mounting slot, opening the unloading channel, and providing guidance for the removal of the chemical drums. During cleaning, the chemical drums are effectively limited to prevent them from being removed from the rectangular frame before cleaning is complete, ensuring the integrity of the cleaning process. During unloading, the channel can be opened quickly and guidance can be provided, ensuring a smooth unloading process and improving operational continuity.

[0017] Optionally, the inner wall surface of the L-shaped limiting strip is provided with ball bearings arranged in a linear array for rotation.

[0018] By adopting the above technical solution, when the chemical drum is placed into or removed from the rectangular frame, the outer wall of the chemical drum contacts the ball bearings on the inner wall of the L-shaped limiting strip. During the movement of the chemical drum, the linear array of ball bearings rotates, converting the sliding friction between the chemical drum and the L-shaped limiting strip into rolling friction, reducing the resistance encountered by the chemical drum during movement; reducing the difficulty of the chemical drum entering and leaving the rectangular frame, avoiding scratches or damage to the outer wall of the chemical drum caused by friction, and reducing the force required to push the chemical drum, thus improving the convenience of loading and unloading.

[0019] Optionally, an L-shaped bracket is fixedly installed on the rear side wall of the ultrasonic cleaning tank, a linear driver is fixedly installed on the L-shaped bracket, a lifting cylinder is fixedly installed on the slider of the linear driver, a push plate is fixedly provided at the lower end of the push rod of the lifting cylinder, and the push plate cooperates with the rectangular frame.

[0020] By adopting the above technical solution, after the chemical drum is cleaned and rotated to the unloading position, the push rod of the lifting cylinder extends, driving the push plate down to the height corresponding to the chemical drum inside the rectangular frame; the linear actuator one is activated, and the slider of the linear actuator one drives the lifting cylinder and the push plate to move horizontally. The push plate contacts the chemical drum and applies a pushing force, pushing the chemical drum out of the rectangular frame; after unloading is completed, the push rod of the lifting cylinder retracts, driving the push plate up, and the slider of the linear actuator one drives the lifting cylinder and the push plate to move in the opposite direction back to the initial position, preparing for the next push; thus, the automatic unloading of the cleaned chemical drum is achieved, eliminating the need for manual handling and improving unloading efficiency. At the same time, the cooperation between the push plate and the rectangular frame ensures that the pushing force is uniform, preventing the chemical drum from tipping over or shifting during the unloading process.

[0021] Optionally, the left and right side walls of the ultrasonic cleaning tank are fixedly installed with limiting plates, which are rotatably connected to adjacent T-shaped turntables respectively. The upper end of each limiting plate is provided with a clearance opening corresponding to the rectangular frame.

[0022] By adopting the above technical solution, during the rotation of the chemical drum driven by the rotating bracket, the limiting plate is fixed to the left and right side walls of the ultrasonic cleaning tank and rotates and connects with the T-shaped turntable, blocking both ends of the rectangular frame to prevent the chemical drum from falling from both ends of the rectangular frame before rotating to the top unloading position; when the chemical drum rotates to the top unloading position, the rectangular frame aligns with the clearance opening at the top of the limiting plate, and the clearance opening provides a channel for the removal of the chemical drum without obstructing the unloading operation; this ensures the safety of the chemical drum during the cleaning and transportation process, avoids equipment damage or damage to the chemical drum due to accidental falling, and at the same time, the setting of the clearance opening ensures that the unloading process proceeds normally and does not affect the overall operation efficiency.

[0023] Optionally, the drive assembly includes a motor, a drive pulley, a driven pulley, and a belt. The motor is fixedly mounted on an L-shaped bracket, the drive pulley is fixedly mounted on the output shaft of the motor, and the driven pulley is fixedly mounted on the rotating shaft of the T-shaped turntable on the right side. The drive pulley and the driven pulley are connected by belt drive.

[0024] By adopting the above technical solution, the motor is fixed on the L-shaped bracket to maintain stability. After the motor starts, its output shaft drives the drive pulley to rotate. The drive pulley transmits power to the driven pulley through the belt. The driven pulley is fixed on the rotating shaft of the right T-shaped turntable, which in turn drives the right T-shaped turntable to rotate. The right T-shaped turntable drives the entire rotating bracket to rotate, so that the chemical drum rotates along the axial direction of the rotating bracket.

[0025] Optionally, a U-shaped frame and a second linear actuator are provided on the right side of the ultrasonic cleaning tank. The U-shaped frame is axially aligned with the rectangular frame that has been rotated to the top. A pusher plate is fixedly installed on the slider of the second linear actuator, and the pusher plate is configured to cooperate with the U-shaped frame.

[0026] By adopting the above technical solution, the chemical drums to be cleaned are placed in the U-shaped frame, which initially positions the chemical drums to ensure that the arrangement direction of the chemical drums is consistent with that of the rectangular frame. The second linear actuator is activated, and the slider of the second linear actuator drives the pusher plate to move horizontally. The pusher plate pushes the chemical drums in the U-shaped frame, pushing the chemical drums from the U-shaped frame to the corresponding rectangular frame, thus completing the loading. This achieves automatic loading of the chemical drums to be cleaned, improving loading efficiency. At the same time, the cooperation between the U-shaped frame and the rectangular frame ensures accurate loading of the chemical drums, avoiding the impact of positional deviation on subsequent cleaning operations.

[0027] Optionally, a belt conveyor is provided on the left side of the ultrasonic cleaning tank, and the clearance opening is configured to cooperate with the conveyor belt of the belt conveyor.

[0028] By adopting the above technical solution, after the chemical drums are cleaned, they are moved out from the clearance opening at the upper end of the limiting plate. The clearance opening cooperates with the conveyor belt of the belt conveyor, so that the moved chemical drums fall directly onto the conveyor belt. The belt conveyor starts, and the conveyor belt drives the chemical drums to move along the conveying direction, transporting the cleaned chemical drums to the next process or collection area. This realizes the automatic transportation of cleaned chemical drums. At the same time, the cooperation between the conveyor belt and the clearance opening ensures the smooth transfer of chemical drums, improving the overall automation level of the operation.

[0029] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0030] 1. When the drive unit is working, it drives the T-shaped turntable to rotate. The T-shaped turntable moves the chemical drum from above the ultrasonic cleaning tank into the tank through the rotating support, so that the chemical drum is completely immersed in the cleaning solution. During the rotation of the chemical drum with the rotating support, the internal air can be completely discharged, avoiding the inability of the cleaning solution to fill the inside of the chemical drum due to residual air. The ultrasonic cleaning tank starts to clean the inner and outer walls of the chemical drum. After cleaning, the drive unit continues to drive the rotating support to rotate, moving the chemical drum out of the cleaning solution and back to the top of the tank, completing the cleaning process. This realizes the automatic delivery and immersion cleaning of chemical drums, reducing manual intervention and improving cleaning efficiency. At the same time, the radial limit of the rectangular frame ensures that the cleaning solution inside the chemical drum can be completely discharged, avoiding residue.

[0031] 2. When the rotating bracket rotates the cleaned chemical drum above the ultrasonic cleaning tank, the drum opening faces downwards, and the residual cleaning solution flows out along the opening. The upward-facing V-shaped manifold receives the outflowing cleaning solution. With the guiding effect of the V-shaped structure, the cleaning solution is concentrated at the bottom of the manifold and then discharged through a fixed pipe. This achieves the separation of the cleaning solution containing high concentrations of impurities from the low concentrations of impurities in the ultrasonic cleaning tank, avoiding cross-contamination and preventing the used cleaning solution inside the chemical drum from being directly discharged into the ultrasonic cleaning tank, which would cause excessively high concentrations of impurities in the cleaning solution and reduce waste of cleaning solution.

[0032] 3. During the cleaning process of the chemical drums, the push rod of the baffle cylinder is in the extended state, and the baffle rotates to the position that mates with the mounting groove above the T-shaped turntable on the left, blocking the chemical drums within the rectangular frame and preventing them from being moved out of the rectangular frame before cleaning is completed, thus ensuring the integrity of the cleaning process. When the chemical drums are cleaned and need to be unloaded, the push rod of the baffle cylinder retracts, pulling the connecting rod to rotate in the opposite direction, which in turn drives the baffle to rotate around the rotation axis, causing the baffle to disengage from the mounting groove, opening the unloading channel and providing guidance for the removal of the chemical drums, ensuring a smooth unloading process and improving the continuity of operations.

[0033] 4. During the cleaning process of the chemical drums, the push rod of the lifting cylinder pushes the push plate down to the inside of the right-side clearance opening. The push plate blocks the right-side clearance opening to prevent the chemical drum from falling out of the clearance opening before cleaning is complete. The linear actuator is activated, and the slider of the linear actuator drives the lifting cylinder and the push plate to move horizontally. The push plate contacts the chemical drum and applies a pushing force, pushing the chemical drum out of the rectangular frame. This achieves automatic unloading of the chemical drums after cleaning, eliminating the need for manual handling and improving unloading efficiency. At the same time, the cooperation between the push plate and the rectangular frame ensures that the pushing force is evenly applied, preventing the chemical drums from tipping over or shifting during the unloading process.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to Figures 1-11. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of this application are within the scope of protection of this application.

[0047] Referring to Figures 1 and 2, this embodiment provides a chemical drum cleaning device, including an ultrasonic cleaning tank 1, a rotating support 2, and a drive assembly 3. The two ends of the rotating support 2 are rotatably installed on the left and right walls of the ultrasonic cleaning tank 1, respectively. The chemical drums are immersed in the ultrasonic cleaning tank 1 through the rotating support 2, so that the inside of the chemical drums is filled with cleaning fluid for cleaning, reducing the amount of manual labor. A U-shaped frame 20 and a linear actuator 21 are provided on the right side of the ultrasonic cleaning tank 1. The linear actuator 21 can be a linear motor or an electric slide. The U-shaped frame 20 is axially aligned with the rectangular frame 203 that rotates to the top. The inner width of the U-shaped frame 20 is the same as the inner width of the rectangular frame 203, which is used for precise positioning and guidance of the chemical drums. A pusher plate 22 is fixedly installed on the slider of the linear actuator 21. The pusher plate 22 extends into the inside of the U-shaped frame 20 from above. A belt conveyor 23 is provided on the left side of the ultrasonic cleaning tank 1.

[0048] Referring to Figures 2, 4, and 5, the rotating bracket 2 includes two T-shaped turntables 201 arranged opposite to each other. The rotation shafts 2011 of the two T-shaped turntables 201 are rotatably connected to the corresponding side walls of the ultrasonic cleaning tank 1. The disc body of the T-shaped turntable 201 is evenly provided with multiple mounting grooves 2012 along the circumference (refer to Figure 10). Four L-shaped limiting strips 202 are fixedly arranged between two mounting grooves 2012 corresponding to each other along the axial direction of the T-shaped turntable 201. The four L-shaped limiting strips 202 located in the same mounting groove 2012 cooperate to form a rectangular frame 203 (refer to Figure 6). The pusher plate 22 is arranged in cooperation with the uppermost rectangular frame 203.

[0049] The chemical drums to be cleaned are arranged linearly inside the U-shaped frame 20. The linear actuator 21 is controlled to work. The slider of the linear actuator 21 drives the pusher plate 22 to move to the left. The pusher plate 22 pushes the chemical drums inside the U-shaped frame 20 into the rectangular frame 203. The inner wall of the L-shaped limiting bar 202 is linearly arrayed with rotating ball bearings 14 (see Figure 7). The ball bearings 14 are used to reduce the friction when the chemical drum enters and exits the rectangular frame 203. The rectangular frame 203 radially limits the chemical drum and controls the direction of the drum opening. The drive component 3 drives the T-shaped turntable 201 and the rotating bracket 2 to rotate, transporting the chemical drum from above the ultrasonic cleaning tank 1 into the interior of the ultrasonic cleaning tank 1, so that the cleaning fluid is poured into the chemical drum. The ultrasonic cleaning tank 1 cleans the interior of the chemical drum. After cleaning, the rectangular frame 203 drives the chemical drum to rotate to the top of the rotating bracket 2, which can quickly discharge the used cleaning fluid from the chemical drum.

[0050] Referring to Figure 2, the drive assembly 3 is mounted on the ultrasonic cleaning tank 1. The drive assembly 3 includes a motor 31, a driving pulley 32, a driven pulley 33, and a belt 34. An L-shaped bracket 15 is fixedly installed on the rear side wall of the ultrasonic cleaning tank 1. The motor 31 is fixedly installed on the L-shaped bracket 15. The driving pulley 32 is fixedly installed on the output shaft of the motor 31. The driven pulley 33 is fixedly installed on the rotating shaft 2011 of the T-shaped turntable 201 on the right side. The driving pulley 32 and the driven pulley 33 are connected by the belt 34. The motor 31 drives the rotating bracket 2 to rotate, immersing the chemical drum in the ultrasonic cleaning tank 1 for cleaning. The control circuit... When the machine 31 is working, the output shaft of the motor 31 drives the drive pulley 32 to rotate. The drive pulley 32 drives the driven pulley 33 to rotate through the belt 34. The driven pulley 33 drives the T-shaped turntable 201 on the right side to rotate, which in turn drives the rectangular frame 203 to rotate. This causes the chemical drums arranged inside the rectangular frame 203 to rotate into the ultrasonic cleaning tank 1. The ultrasonic cleaning tank 1 then operates. (The working principle of ultrasonic cleaning is to generate high-frequency mechanical vibration through an ultrasonic generator, which causes the cleaning fluid to form microbubbles. The impact force generated by the bursting of the bubbles can remove the residual adhering substances on the inner and outer walls of the chemical drums without dead angles. This is existing technology and will not be described in detail here.)

[0051] Referring to Figures 2, 4, 8, and 11, the system also includes a V-shaped manifold 4. Both ends of the V-shaped manifold 4 are fixedly fitted with fixing pipes 41. The rotating shaft 2011 has a hollow structure. The fixing pipes 41 pass through the rotating shafts 2011 of adjacent T-shaped turntables 201 and are fixedly connected to a fixing seat fixed outside the ultrasonic cleaning tank 1. The fixing pipe 41 on the left side has a closed structure, and the right end of the fixing pipe 41 on the right side is fixedly connected to a conduit 7 via a sealing joint. The opening of the V-shaped manifold 4 faces upwards. The V-shaped manifold 4 is located inside the rotating support 2 and radially corresponds to the rectangular frame 203 that has rotated upwards. To receive the waste liquid discharged from the chemical drums, a filter box 5 is fixedly installed on the outer wall of the ultrasonic cleaning tank 1. The filter box 5 is equipped with a filter layer 6 (the filter layer 6 can be a filter cotton layer, an activated carbon layer, or other materials, selected according to the characteristics of the impurities after cleaning the chemical drums). The end of the conduit 7 away from the fixed pipe 41 extends to the upper interior of the filter box 5. A return pipe 8 is fixedly installed at the lower interior of the filter box 5. The end of the return pipe 8 away from the filter box 5 extends to the upper interior of the ultrasonic cleaning tank 1. A circulation pump 9 is fixedly installed on the outer wall of the ultrasonic cleaning tank 1. The circulation pump 9 is connected in series in the pipeline of the return pipe 8.

[0052] Cleaning fluid is injected into the ultrasonic cleaning tank 1 to ensure that the liquid level of the cleaning fluid does not exceed the opening of the V-shaped manifold 4 after the chemical drum enters the ultrasonic cleaning tank 1. This prevents the cleaning fluid from overflowing into the V-shaped manifold 4 before use. During the rotation of the rectangular frame 203, the cleaned chemical drum is moved to the top of the ultrasonic cleaning tank 1. At this time, the opening of the chemical drum is facing down, and the cleaning fluid inside the chemical drum is discharged downwards into the V-shaped manifold 4. Then, it flows into the filter box 5 through the fixed pipe 41 and the conduit 7 on the right side. The filter layer 6 filters and intercepts the impurities inside the cleaning fluid. The filtered cleaning fluid is collected at the bottom of the filter box 5 and is transported back to the ultrasonic cleaning tank 1 by the circulation pump 9. This prevents the cleaning fluid inside the chemical drum from being directly discharged into the ultrasonic cleaning tank 1, which would cause the cleaning fluid to become contaminated too quickly. Moreover, by continuously filtering the used cleaning fluid, the filtration effect of impurities is improved, and the service life of the cleaning fluid is extended.

[0053] Referring to Figures 2 and 3, a baffle 10 is rotatably mounted on the upper left side wall of the ultrasonic cleaning tank 1 via a rotating shaft 13. The baffle 10 is fixedly connected to the rotating shaft 13. The baffle 10 cooperates with the mounting groove 2012 above the T-shaped turntable 201 on the left side to limit the leftmost chemical drum and prevent it from moving out of the mounting groove 2012 before cleaning is complete. A connecting rod 11 is fixedly mounted on the front end of the rotating shaft 13 of the baffle 10. A baffle cylinder 12 is rotatably mounted on the front side of the ultrasonic cleaning tank 1. The push rod end of the baffle cylinder 12... The connecting rod 11 is rotatably connected to the end away from the rotating shaft 13. The baffle 10 is configured to cooperate with the conveyor belt of the belt conveyor 23. A linear driver 16 is fixedly installed on the L-shaped bracket 15. The linear driver 16 can be a linear motor or an electric slide table. A lifting cylinder 17 is fixedly installed on the slider of the linear driver 16. A push plate 18 is fixedly installed at the lower end of the push rod of the lifting cylinder 17. The push plate 18 cooperates with the rectangular frame 203 (when the rectangular frame 203 rotates to the top of the rotating bracket 2, it is vertically aligned with the push plate 18). Correspondingly, the push plate 18 can be vertically inserted into the uppermost rectangular frame 203 to push the chemical drum to move. After the chemical drum is cleaned, the rectangular frame 203 drives the chemical drum to rotate to correspond with the mounting slot 2012, controlling the baffle cylinder 12 to work. The push rod of the baffle cylinder 12 pushes the connecting rod 11 to rotate, thereby driving the baffle 10 to rotate, so that the upper end of the baffle 10 rotates to cooperate with the conveyor belt of the belt conveyor 23. Control the linear driver 16 to work, and the slider of the linear driver 16 drives the lifting cylinder 17 to move (this... When the push rod of the lifting cylinder 17 is in the extended state, the lifting cylinder 17 drives the push plate 18 to move, pushing the cleaned chemical drum from the upper rectangular frame 203 to the belt conveyor 23 under the guidance of the baffle 10. Then, the lifting cylinder 17 is controlled to run in reverse, and the push rod of the lifting cylinder 17 retracts, driving the push plate 18 to move above the uppermost chemical drum. The linear drive 16 is then controlled to run in reverse, moving the lifting cylinder 17 and the push plate 18 to the right side of the rectangular frame 203, so that the chemical drum can be pushed again.

[0054] Limiting plates 19 are fixedly installed on both the left and right side walls of the ultrasonic cleaning tank 1. Each limiting plate 19 is rotatably connected to an adjacent T-shaped turntable 201 via bearings. The inner end face of the limiting plate 19 is clearance-fitted with the two end faces of the rectangular frame 203, limiting only the axial movement of the chemical drum. This prevents the chemical drum from falling off both ends of the rectangular frame 203 during cleaning and conveying, thus preventing incomplete drainage of the cleaning fluid inside the chemical drum. It also does not affect the loading and unloading operations of the chemical drum. The upper end of each limiting plate 19 has a groove that connects to the rectangular frame 203. The clearance opening 191 corresponding to frame 203 (refer to Figures 2 and 9) is used for unloading chemical drums. The upper surface of the conveyor belt of belt conveyor 23 is lower than the lower edge of clearance opening 191 on the left side of limit plate 19. After the lifting cylinder 17 and push plate 18 move to the right side of rectangular frame 203, the push rod of lifting cylinder 17 pushes push plate 18 down to the inside of clearance opening 191 on the right side. The push plate 18 is used to block clearance opening 191 on the right side to prevent chemical drums from falling from clearance opening 191 on the right side when cleaning is not completed.

[0055] The implementation principle of a chemical drum cleaning device according to an embodiment of this application is as follows:

[0056] Before the chemical drums are loaded, the push rod of the lifting cylinder 17 is in a retracted state, and the bottom of the push plate 18 is higher than the top of the uppermost rectangular frame 203 to prevent the push plate 18 from obstructing the loading process of the chemical drums; the push rod of the baffle cylinder 12 is in an extended state, and the clearance opening 191 on the left is blocked by the baffle 10, so that the chemical drums are linearly arranged inside the U-shaped frame 20 with the drum opening facing down. Then, the linear drive 21 is controlled to work, and its slider drives the push plate 22 to move to the left, pushing the chemical drums in the U-shaped frame 20 to the uppermost rectangular frame 203. The rectangular frame 203 can radially limit the chemical drums and ensure that the opening direction of the chemical drums is consistent. The control motor 31 operates intermittently, its output shaft driving the drive pulley 32 to rotate. The drive pulley 32 drives the driven pulley 33 to rotate via the belt 34, which in turn drives the right-side T-shaped turntable 201 to rotate and simultaneously drives the rectangular frame 203 to rotate. This transports the chemical drums arranged inside the rectangular frame 203 from above the ultrasonic cleaning tank 1 into the tank, allowing the cleaning solution to be poured into the chemical drums. Subsequently, the ultrasonic cleaning tank 1 operates to clean the inside of the chemical drums. When the motor 31 stops working, the U-shaped frame 20 aligns axially with the uppermost rectangular frame 203. Taking advantage of the interval when the motor 31 stops, the chemical drums on the U-shaped frame 20 are pushed forward. At this point, the uppermost rectangular frame 203 is simultaneously filled with cleaning fluid into the chemical drums immersed in the ultrasonic cleaning tank 1, and ultrasonic cleaning time is reserved. This cycle continues until all the rectangular frames 203 are filled with chemical drums. Then, the lifting cylinder 17 is controlled to move the push plate 18 down to the right-side clearance opening 191, preventing the chemical drums inside the rectangular frames 203 from being moved out of the right-side clearance opening 191. After the initially placed chemical drums are cleaned, the rectangular frame 203 continues to rotate the chemical drums to the top of the rotating support 2. At this time, the opening of the chemical drums is facing down, and the used cleaning fluid can be quickly discharged from the chemical drums.

[0057] The cleaning solution discharged from the chemical drum falls into the V-shaped manifold 4 and is then guided to the upper part of the filter box 5 through the fixed pipe 41 and conduit 7 on the right side. The filter layer 6 filters and intercepts impurities inside the cleaning solution. The filtered cleaning solution collects at the bottom of the filter box 5 and is then pumped back to the interior of the ultrasonic cleaning tank 1 by the circulation pump 9. This not only prevents the cleaning solution from being directly discharged into the ultrasonic cleaning tank 1 after use from the chemical drum, which would cause the cleaning solution to become contaminated too quickly, but also improves the impurity filtration effect through continuous filtration, thus extending the service life of the cleaning solution.

[0058] Throughout the cleaning and rotation process, the limiting plate 19 blocks the end of the rectangular frame 203 to prevent the chemical drum from falling off the rectangular frame 203 before it rotates to the top of the rotating support 2, thus ensuring that the cleaning liquid can be completely discharged. When the rectangular frame 203 drives the cleaned chemical drum to the position corresponding to the clearance opening 191, the baffle cylinder 12, which is rotated on the front side of the ultrasonic cleaning tank 1, is activated. The push rod of the baffle cylinder 12 pushes the connecting rod 11 to rotate, thereby driving the baffle 10 to rotate. The upper end of the baffle 10 rotates to match the conveyor belt of the belt conveyor 23 set on the left side of the ultrasonic cleaning tank 1 (the upper surface of the conveyor belt of the belt conveyor 23 is lower than the lower edge of the clearance opening 191 on the left side of the limiting plate 19), thus preparing for subsequent unloading. Then, the linear actuator 16 is started. At this time, the push rod of the lifting cylinder 17 is in the extended state. The slider of the linear actuator 16 drives the lifting cylinder 17 to move. The lifting cylinder 17 then drives the push plate 18, which is fixed at the lower end of its push rod, to move. Under the guidance of the baffle 10, the cleaned chemical drum is pushed from the upper rectangular frame 203 to the belt conveyor 23. After unloading, the lifting cylinder 17 is controlled to run in reverse. Its push rod retracts and drives the push plate 18 to move above the uppermost chemical drum. Then, the linear actuator 16 is controlled to run in reverse, moving the lifting cylinder 17 and the push plate 18 to the right side of the rectangular frame 203. The motor 31 is started again to unload the next set of cleaned chemical drums.

[0059] Furthermore, in the description of this application, the terms "installation", "connection", "linking", and "setting" should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
