[0002] Dialysate is a vital solution in the hemodialysis process, usually containing electrolytes, acids, alkalis, sodium, potassium, calcium and other components, which help remove metabolic waste and excess fluid from the blood during the dialysis process. Hemodialysis concentrate packaging barrels are containers used to store and transport hemodialysis concentrates (such as dialysate concentrates). After the dialysate is used, the packaging barrels need to be cleaned before they can be reused.

[0003] The patent document with the announcement number CN205253687U discloses a semi-automatic cleaning device for hemodialysis concentrate packaging barrels, including a frame, a cleaning turntable, a spray nozzle, a spray head, a water accumulation tray, a circulating water tank, a circulating water pump, a filter, a turntable motor, a V-belt pulley, a V-belt, a worm, a worm gear and a barrel rack. The semi-automatic cleaning device for hemodialysis concentrate packaging barrels can clean the inner wall and the outer wall at the same time, thereby ensuring the quality of the barrel after cleaning. The water used to clean the outer wall of the packaging barrel is filtered circulating water, which greatly saves production costs. Since the equipment is used for cleaning, human resource costs are saved and unqualified quality is avoided. Since multiple cleaning nozzles are provided on the cleaning turntable, multiple packaging barrels can be cleaned at the same time for the inner and outer walls, thereby improving production efficiency.

[0030] refer to Figure 4 , Figure 6 as well as Figure 7The adjusting mechanism 40 includes a mounting cylinder 41, a connecting shaft 42, a one-way bearing 43 and a second torsion spring 44. The mounting cylinder 41 is fixedly mounted on the side wall of the upper support 21. The side wall of the mounting cylinder 41 is fixedly mounted with a side cylinder 411. The connecting shaft 42 is rotatably assembled inside the mounting cylinder 41. The end of the connecting shaft 42 extends to the inside of the side cylinder 411, and the connecting shaft 42 is coaxially fixed with the support shaft 213. The inner ring of the one-way bearing 43 is slidably assembled on the connecting shaft 42. The second torsion spring 44 is sleeved on the connecting shaft 42, and the two ends of the second torsion spring 44 are respectively connected to the connecting shaft 41. 2 and the side cylinder 411 are fixed, the outer ring of the one-way bearing 43 is slidably assembled in the mounting cylinder 41, the one-way bearing 43 and the connecting shaft 42 can limit the support shaft 213, so that the mounting seat 212 can only rotate in one direction, and with the cooperation of the second torsion spring 44, a reset thrust is applied to the connecting shaft 42, so that the connecting shaft 42 and the mounting seat 212 can be maintained in an inclined state when not subjected to external thrust, thereby facilitating the adjustment of the angle of the nozzle 11, so that the nozzle 11 can maintain inclined spraying, and improve the spraying coverage area of ​​the nozzle 11.

[0031] refer to Figure 6 and Figure 7 A plurality of axial grooves 412 and annular grooves 413 are provided inside the mounting tube 41. The plurality of axial grooves 412 are evenly distributed in an annular manner along the circumferential direction of the mounting tube 41 and are all connected to the annular grooves 413. An outer key 431 is fixedly installed on the outer ring of the one-way bearing 43, and the outer key 431 is slidably connected inside one of the axial grooves 412. A sliding groove 421 is provided on the connecting shaft 42 along its axial direction. An inner key 432 is fixedly installed on the inner ring of the one-way bearing 43, and the inner key 432 is slidably connected inside the sliding groove 421, so that the one-way bearing 43 can slide inside the mounting tube 41, so that the outer key 431 can enter the annular groove 413 from the axial groove 412, thereby releasing the restriction on the outer ring of the one-way bearing 43, and allowing the connecting shaft 42 to rotate and reset under the drive of the second torsion spring 44.

[0032] refer to Figure 2 , Figure 5 and Figure 8The transmission assembly 50 includes a transmission gear 51, a side plate 52, a pressure plate 53 and a first spring 54. The transmission gear 51 is fixedly mounted on the support shaft 213, the side plate 52 is fixedly mounted on the top of the vertical plate 31, the top of the pressure plate 53 is rotatably connected to the side plate 52, and the bottom end of the pressure plate 53 extends to one side of the transmission gear 51. A first spring 54 is arranged between the pressure plate 53 and the side plate 52. When the side plate 52 follows the vertical plate 31 to descend, the pressure plate 53 can press the transmission gear 51 to rotate, so that the mounting seat 212 rotates a certain angle. When the side plate 52 rises, the transmission gear 51 is restricted by the one-way bearing 43 and cannot rotate in the opposite direction. Then the side plate 52 is blocked by the transmission gear 51, enters the pressure plate 53 and compresses the first spring 54, so that the pressure plate 53 can move above the transmission gear 51.

[0033] refer to Figure 6 and Figure 7 The reset mechanism 60 includes a slope platform 61, a slider 62 and a second spring 63. The slope platform 61 is fixedly connected to the side wall of the mounting tube 41, and the slope platform 61 is arranged coaxially with the connecting shaft 42 in an arc shape. The slider 62 is fixedly installed on the inner ring of the one-way bearing 43, and the end of the slider 62 is arranged on the slope platform 61. The second spring 63 is arranged on the side of the one-way bearing 43 away from the slider 62. As the connecting shaft 42 drives the inner ring of the one-way bearing 43 to rotate, the slider 62 moves along the slope platform 61, and the slope platform 61 pushes the slider 62 to make the one-way bearing 43 slide in the mounting tube 41 and squeeze the second spring 63. When the connecting shaft 42 drives the inner ring of the one-way bearing 43 to rotate, the slider 62 moves along the slope platform 61. The slope platform 61 pushes the slider 62 to make the one-way bearing 43 slide in the mounting tube 41 and squeeze the second spring 63. The shaft 42 rotates to a certain angle with the inner ring of the one-way bearing 43. Under the push of the slope platform 61, the outer key 431 enters the annular groove 413 from the axial groove 412. The outer ring of the one-way bearing 43 loses its limit. Under the action of the second torsion spring 44, the connecting shaft 42 drives the one-way bearing 43 and the support shaft 213 to rotate, so that the nozzle 11 is reset. At this time, the outer key 431 moves in the annular groove 413 to the side of the next axial groove 412. The second spring 63 pushes the one-way bearing 43 to make the outer key 431 enter the axial groove 412, completing the automatic reset of the one-way bearing 43, and then the nozzle 11 performs the next round of angle adjustment.

[0034] Working principle: put the packaging barrel cover outside the nozzle 11, and support the packaging barrel with the crossbar 13 and the inner wall of the cleaning tank 10, and spray the cleaning liquid with the nozzle 11 to flush and clean the bottom of the packaging barrel, and the cylinder 34 drives the vertical plate 31 to move up and down, so that the two racks 32 are alternately engaged with the swing gear 33, and the swing gear 33 is driven to rotate alternately forward and reverse, and then the upper support 21 and the nozzle 11 are swung and sprayed, so as to increase the direct coverage width of the cleaning liquid; When the vertical plate 31 moves downward, the pressing plate 53 in the side plate 52 presses the transmission gear 51 to rotate, so that the mounting seat 212 and the nozzle 11 rotate a certain angle, and under the restriction of the one-way bearing 43 and the second torsion spring 44 on the connecting shaft 42, the mounting seat 212 and the nozzle 11 are kept in an inclined state, so that the cleaning liquid can be directly sprayed to a farther position on the bottom of the packaging barrel. When the side plate 52 rises, the side plate 52 is blocked by the transmission gear 51, enters the inside of the pressing plate 53 and compresses the first spring 54, so that the pressing plate 53 can move above the transmission gear 51. When the vertical plate 31 descends next time, the transmission gear 51 is pushed to rotate again, thereby changing the inclination angle of the nozzle 11 little by little, so that the nozzle 11 can cover the entire bottom of the packaging barrel when the cleaning liquid is sprayed in the swing. When the mounting seat 212 and the nozzle 11 rotate, the connecting shaft 42 drives the inner ring of the one-way bearing 43 to rotate, and the slope platform 61 pushes the slider 62 to make the one-way bearing 43 slide in the mounting tube 41 and squeeze the second spring 63. When the connecting shaft 42 rotates to a certain angle with the inner ring of the one-way bearing 43, under the push of the slope platform 61, the outer key 431 completely enters the annular groove 413 from the axial groove 412, and the outer ring of the one-way bearing 43 loses its limit. Under the action of the second torsion spring 44, the connecting shaft 42 drives the one-way bearing 43 and the supporting shaft 213 to rotate, so as to reset the nozzle 11. At this time, the outer key 431 moves in the annular groove 413 to the side of the next axial groove 412, and the second spring 63 pushes the one-way bearing 43 to make the outer key 431 enter the axial groove 412, completing the automatic reset of the one-way bearing 43, and then the nozzle 11 can perform the next round of angle adjustment, and repeatedly flush and clean the bottom of the packaging barrel.

[0035] In the present invention, the nozzle 11 is swung to spray the cleaning liquid, so that the direct flushing trajectory of the cleaning liquid can completely cover the bottom of the packaging barrel in width. While the nozzle 11 is swung, the nozzle 11 is gradually rotated and tilted, and then the covering position of the cleaning liquid is gradually moved forward along the length direction of the cleaning barrel until the bottom of the packaging barrel is completely covered. While ensuring efficient cleaning of the bottom of the packaging barrel, the direct flushing area of ​​the bottom of the packaging barrel can be effectively increased, and the flushing dead angle can be reduced or even eliminated, thereby improving the flushing effect of the packaging barrel.

[0036] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
