Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chemical equipment cleaning, in particular to a chemical barrel cleaning device. BACKGROUND

[0002] The chemical barrel is the core container for material storage and transportation in the chemical industry. Its recovery and cleaning after use not only is an important way to realize resource recycling, but also is a key link to meet the requirements of environmental protection compliance. At present, with the continuous tightening of national environmental protection requirements and the deepening of the "double carbon" target, the cleanliness, operation efficiency and waste liquid recovery rate in the cleaning process of the chemical barrel have become the core demands of the industry that need to be optimized.

[0003] The ultrasonic cleaning technology has the unique advantage of stripping the residual attachments on the inner and outer walls of the barrel without dead angles due to high-frequency vibration, and is particularly suitable for cleaning small-diameter chemical barrels (the diameter is much smaller than the size of the barrel body). Due to the narrow opening of this type of chemical barrel, it is difficult for traditional spraying and brushing methods to reach the deep part of the barrel. However, the ultrasonic energy can penetrate into all areas of the barrel with cleaning liquid, which can theoretically effectively solve the problem of cleaning blind area of small-diameter barrels. However, the existing ultrasonic cleaning application scheme has not fully adapted to the structural characteristics of small-diameter chemical barrels, resulting in that the advantages of this technology have not been fully released.

[0004] Referring to the Chinese patent document with publication number CN210280104U and publication date April 10, 2020, entitled "Chemical barrel cleaning device", which includes a circulating track and a frame, the frame is provided with a driving mechanism and a chemical barrel clamp; the driving mechanism can drive the frame to slide along the circulating track, and can drive the chemical barrel clamp to realize lifting, rotating and opening and closing actions. A placing platform, a first water tank, a second water tank, a third water tank, a air drying mechanism and a clean chemical barrel placing area are sequentially arranged below the circulating track, wherein the first water tank is provided with an ultrasonic generator.

[0005] Referring to the above-mentioned patent technical solution, the chemical barrel is clamped by the chemical barrel clamp and immersed in the first water tank, and the ultrasonic generator is used to clean the inside of the chemical barrel. However, in actual application, small-diameter chemical barrels have narrow openings and large barrel volumes, and during cleaning, the opening needs to be kept upward to pour in the cleaning liquid, and after cleaning, the opening needs to be kept downward to drain the waste liquid. This turning process still needs to be completed with the assistance of manual labor, which not only has high labor intervention cost, but also is not convenient for continuous conveying and cleaning operation of multiple chemical barrels.

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: 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.

[0030] 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.

[0031] 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.

[0032] 4、In the process of cleaning the chemical barrel, the push rod of the lifting cylinder pushes the push plate to move down to the inside of the avoidance port on the right side, and the push plate is used to block the avoidance port on the right side, so as to avoid the chemical barrel from falling from the avoidance port on the right side when the cleaning is not completed. When the linear driver one starts, the slider of the linear driver one drives the lifting cylinder and the push plate to move in the horizontal direction. The push plate contacts the chemical barrel and applies a pushing force to push the chemical barrel out of the rectangular frame. The automatic unloading of the cleaned chemical barrel is realized, manual handling is not required, the unloading efficiency is improved, and the cooperation of the push plate and the rectangular frame ensures uniform pushing force and avoids the chemical barrel from tilting or deviating during unloading.

[0043] The left and right side walls of the ultrasonic cleaning tank 1 are fixedly provided with limiting discs 19, the limiting discs 19 are rotatably connected with the adjacent T-shaped turntable 201 through bearings, the inner side end surface of the limiting disc 19 is in clearance fit with the two end surfaces of the rectangular frame 203, only the axial movement of the chemical barrel is limited, the chemical barrel is prevented from falling off from the two ends of the rectangular frame 203 during the cleaning and conveying process, the cleaning liquid in the chemical barrel is prevented from not being completely discharged, and the feeding and discharging operations of the chemical barrel are not affected, the upper end of the limiting disc 19 is provided with an avoiding opening 191 corresponding to the rectangular frame 203 (refer to Figure 2 and Figure 9), for the discharge of chemical barrels, the upper surface of the belt conveyor 23 is lower than the lower edge of the left side escape hole 191 of the limiting disc 19, after the lifting cylinder 17 and the push plate 18 move to the right side of the rectangular frame 203, the push rod of the lifting cylinder 17 pushes the push plate 18 to move downward to the inside of the right side escape hole 191, and the push plate 18 is used to block the right side escape hole 191, so as to prevent the chemical barrels from falling from the right side escape hole 191 when the cleaning is not completed.

[0044] The implementation principle of the chemical barrel cleaning device in the embodiment of the application is as follows: Before the chemical barrels 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 end of the uppermost rectangular frame 203, so as to prevent the push plate 18 from hindering the loading process of the chemical barrels; the push rod of the baffle cylinder 12 is in an extended state, the left side escape hole 191 is blocked by the baffle 10, the chemical barrels are linearly arranged in the U-shaped frame 20 with the barrel opening downward, then the linear actuator two 21 is controlled to work, the sliding block drives the push plate 22 to move left, and the chemical barrels in the U-shaped frame 20 are pushed into the uppermost rectangular frame 203, the rectangular frame 203 can limit the chemical barrels in the radial direction and ensure that the barrel openings of the chemical barrels are in the same direction. The motor 31 is controlled to work intermittently, the output shaft drives the driving pulley 32 to rotate, the driving pulley 32 drives the driven pulley 33 to rotate through the belt 34, and then drives the right side T-shaped turntable 201 to rotate and synchronously drives the rectangular frame 203 to rotate, so as to convey the chemical barrels arranged in the rectangular frame 203 from above the ultrasonic cleaning tank 1 to the inside of the ultrasonic cleaning tank 1, so that the cleaning liquid is poured into the chemical barrels, and then the ultrasonic cleaning tank 1 works to clean the inside of the chemical barrels; when the motor 31 stops working, the U-shaped frame 20 corresponds to the uppermost rectangular frame 203 in the axial position, the chemical barrels on the U-shaped frame 20 are pushed into the uppermost rectangular frame 203 at this time by using the gap when the motor 31 stops, and at the same time, the cleaning liquid is poured into the chemical barrels immersed in the ultrasonic cleaning tank 1 and the ultrasonic cleaning time is reserved, so as to circulate until all the rectangular frames 203 have the chemical barrels placed therein, then the lifting cylinder 17 is controlled to work, the lifting cylinder 17 drives the push plate 18 to move downward to the inside of the right side escape hole 191, so as to prevent the chemical barrels in the rectangular frame 203 from moving out of the right side escape hole 191, and after the cleaning of the initially placed chemical barrels is completed, the rectangular frame 203 continues to drive the chemical barrels to rotate to the upper side of the rotary support 2, at this time, the barrel opening of the chemical barrel faces downward, and the cleaning liquid after use can be quickly discharged from the chemical barrel.

[0045] 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.

[0046] 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.
