[0055] The technical solution of the present invention has the following advantages compared with the prior art:

[0056] 1. This invention utilizes an inclined feed chute and transfer chute, as well as an inclined bottom of a first hanging basket, to automatically guide and transport the cleaned items between different processes by using the weight of the items themselves. Furthermore, by moving the first hanging basket up and down in the first cleaning tank, the cleaned items are automatically cleaned as the cleaning liquid flows. This avoids personnel contact with the cleaning process and ensures personal safety.

[0057] 2. The present invention includes a second cleaning tank and a second hanging basket, etc., and uses clean water to wash away excess cleaning liquid and dirt adhering to the surface of the initially cleaned items, thereby ensuring the cleaning quality of the items.

[0058] 3. By setting a first basket door and a second basket door, the present invention avoids friction between the walls of the first and second cleaning tanks during the up-and-down cleaning process of the items to be cleaned, reduces the resistance of the items to be cleaned during up-and-down movement, and extends the service life of the first and second cleaning tanks; moreover, the first and second basket doors can close automatically by their own weight, realizing automated operation.

[0059] 4. By setting a first transition protrusion, the present invention ensures a smooth transition when the lower end of the first door opening arm contacts the first door opening block, thereby ensuring that the first hanging basket door opens smoothly and that the cleaned items slide into the next process relatively stably; by setting a second transition protrusion, the present invention ensures a smooth transition when the lower end of the second door opening arm contacts the second door opening block, thereby ensuring that the second hanging basket door opens smoothly and that the cleaned items slide into the next process relatively stably.

[0060] 5. The present invention opens or closes the feed chute channel by the feed gate, which can buffer the speed at which the object to be cleaned slides down. The feed chute channel is opened in a timely manner to slide the object to be cleaned into the first basket for cleaning. During the cleaning process, the feed chute channel is closed to prevent falling objects from entering the first cleaning tank and causing accidents that could affect the cleaning process.

[0061] 6. The present invention controls the lifting and lowering of the first basket through a first power structure, and controls the cleaning time by controlling the force application time of the first power structure, thereby controlling the cleaning quality; controls the lifting and lowering of the feed gate through a second power structure to ensure that the feed gate opens and closes in a timely manner; controls the lifting and lowering of the second basket through a third power structure, and controls the cleaning time by controlling the force application time of the third power structure, thereby controlling the cleaning quality.

[0062] 7. This invention allows for the disassembly and assembly of the first, second, and third quick-assembly structures using a robotic arm. In conjunction with a crane, it enables the rapid disassembly of easily damaged feed gates, the first and second baskets, and subsequent repair or replacement before rapid reassembly. This achieves automated disassembly and maintenance, enabling remote disassembly and maintenance, reducing human intervention, and ensuring personal safety.

[0063] 8. This invention limits the lifting and lowering positions of the components driven by the first, second, and third power structures using limit switches, ensuring the accuracy of the direction and stroke of movement; and by placing the limit switches away from radioactive environments, the service life of the limit switches is extended.

[0064] 9. The present invention improves the ability to withstand the impact of the cleaned material by using steel plates to make the feed chute, transfer chute and discharge chute.

[0065] 10. The present invention improves the cleaning quality of the object to be cleaned by setting up multiple first cleaning tanks to achieve multiple cleanings. Attached Figure Description

[0080] The first quick-assembly structure 10, the second quick-assembly structure 26, and the third quick-assembly structure 27 are configured with the same structure. For example... Figure 3 As shown, the first quick-release structure 10 includes: a pin 16, a chuck disposed on the pin 16, and a locking pin 18 to prevent the pin 16 from dislodging.

An arc-shaped groove with one open end is provided on the chuck. A protrusion 17 is provided on the connecting portion near the chuck. The protrusion 17 is adapted to slide in the arc-shaped groove. When the protrusion 17 is located at the bottom end of the arc-shaped groove and the chuck is in contact with the connecting portion, the second pin hole and the third pin hole coaxially communicate. Further, as... Figure 3 As shown, two second pin holes perpendicular to the axis of the pin 16 are provided near the end of the pin 16. The axes of the two second pin holes are also perpendicular to each other. Two third pin holes and two locking pins 18 are provided accordingly to further prevent the pin 16 from coming out.

[0081] The limit switch is located away from the first cleaning tank 3 and the second cleaning tank 6.

[0082] The working process of the cleaning device described in this application is briefly described as follows: The object to be cleaned is placed into the feed chute 1 by a robotic arm. The object slides along the feed chute 1 to the front of the feed gate 2, impacts the feed gate 2, and is cushioned. The second power structure drives the feed gate 2 to rise, and the object to be cleaned slides into the first basket 9 in the first cleaning tank 3. The second power structure drives the first basket 9 to move up and down, and the relatively flowing cleaning liquid cleans the object to be cleaned. After cleaning for a period of time, the second power structure drives the first basket 9 to rise to the fourth outlet and align it with the second outlet. At the same time, the lower end of the first door opening arm 12 touches the first door opening block 14, and the first basket door 15 opens, initially... The cleaned items slide out of the first basket 9 and enter the transfer trough 4; the preliminarily cleaned items slide down the transfer trough 4 into the second basket 21 in the second cleaning trough 6; the third power structure drives the second basket 21 to move up and down, and the relatively flowing clean water cleans the preliminarily cleaned items; after cleaning for a period of time, the third power structure drives the second basket 21 to rise to the seventh outlet and align with the fifth outlet. At the same time, the lower end of the second door opening arm 25 presses against the second door opening block 23, the second basket door 22 opens, the cleaned items slide out of the second basket 21 and enter the unloading chute 7, and finally, along the slide of the unloading chute 7, are discharged from the sixth outlet.

[0083] The disassembly, assembly, and maintenance process of the cleaning device described in this application is briefly described as follows: A crane lifts the feed gate 2, and a robotic arm pulls out the locking pin 18, rotates the chuck counterclockwise, and pulls out the pin shaft 16 to remove the feed gate 2. The crane then lifts the feed gate 2 for maintenance or replacement. The crane first removes the first tank cover 20, then lifts the first basket 9, and a robotic arm pulls out the locking pin 18, rotates the chuck counterclockwise, and pulls out the pin shaft 16 to remove the first basket 9. The crane then lifts the first basket 9 for maintenance or replacement. After removing the first basket 9, the crane uses a lifting device to remove the filter 8 from the first cleaning tank 3 for cleaning, maintenance, or replacement. The same method is used to disassemble and remove the filter 8 from the second basket 21 and the second cleaning tank 6.

[0084] After the above maintenance and replacement work is completed, the crane lifts the feed gate 2, inserts the pin 16 using a robotic arm, and rotates the chuck clockwise. When the protrusion 17 is at the bottom of the arc-shaped groove and the chuck is in contact with the connecting part, the second pin hole and the third pin hole are coaxially connected. The locking pin 18 is then inserted, and the feed gate 2 is installed. The crane then uses a lifting device to lift the filter 8 in the first cleaning tank 3 to the installation position. Next, the crane lifts the first basket 9, inserts the pin 16 using a robotic arm, and rotates the chuck clockwise. When the protrusion 17 is at the bottom of the arc-shaped groove and the chuck is in contact with the connecting part, the second pin hole and the third pin hole are coaxially connected. The locking pin 18 is then inserted, and the first basket 9 is installed. Finally, the crane lifts the first tank cover 20 and installs it in place. The same method is used to lift the second basket 21 and the filter 8 in the second cleaning tank 6.

[0085] As an alternative implementation, instead of having the first and second transition bumps have a beveled transition shape, both the first and second transition bumps can have an arc-shaped transition shape.

[0086] As an alternative implementation, the hydraulic cylinder is replaced with an air cylinder.

[0087] As an alternative implementation, the hydraulic cylinder can be replaced with a reciprocating linear motor.

[0088] As an alternative implementation method, such as Figure 2 As shown, the upper end of the first door opening arm 12 is connected to the first groove cover 20, instead of the upper end of the first door opening arm 12 being connected to the fixed support 13.

[0089] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
