Description

Technical Field

[0001] The invention specifically relates to a fully automatic cleaning machine and a cleaning method for pharmaceutical use, and belongs to the technical field of cleaning machines. Background Art

[0002] Glassware is an essential experimental and testing container for pharmaceutical production. Glassware needs to be cleaned after use, and the cleaning quality needs to be guaranteed. When the container cannot be thoroughly cleaned, the background residue of the container will cause deviation in the test data. For example, a small difference in the content at the nanogram level will also affect the accuracy of the measurement result. Existing cleaning equipment, such as Chinese patent publication number: CN107755354A, discloses an ultrasonic cleaning box, including a cleaning tank and a basket. During cleaning, water is pumped to the nozzle through the water supply tank, thereby achieving spray cleaning. The sewage after spray cleaning flows out from the drainage sleeve into the water collection tank for collection, thereby preventing the sewage after cleaning from flowing into the cleaning liquid in the upper box body. However, the In actual use, after ultrasonic cleaning, the utensils are still placed in the cleaning machine. When they are taken out, the dirt in the cleaning liquid will adhere to the surface of the utensils, and the cleanliness of the utensils cannot be guaranteed. For this reason, China Patent Authorization Announcement No.: CN220825281U discloses an ultrasonic spray combined cleaning device, which allows the utensils to be placed horizontally in an ultrasonic cleaning box, and the cleaned utensils are inverted in the ultrasonic cleaning box. The external water inlet pipe cleans the utensils again to prevent dirt from remaining on the surface of the utensils. However, when the existing cleaning machine is cleaning, it is necessary to continuously drain and replenish water in the cleaning chamber to achieve flow rinsing of the utensils until the number of cleaning times is reached, and the consumption of clean water is serious, and the cleaning quality cannot be monitored.

[0010] Furthermore, a clean water control unit is arranged between the immersion chamber and the pressure variable frequency pump, and the clean water control unit includes a clean water temporary storage tank, and the output end of the clean water temporary storage tank is provided with a connection to a heater, and the output end of the heater is provided with a first temperature transmitter; the clean water temporary storage tank is provided with a water inlet pipe, an exhaust head, a first water quality monitoring unit and a first liquid level monitoring unit; the water inlet pipe is connected to the pressure variable frequency pump through a water supply valve; the second temperature transmitter, the second water quality monitoring unit and the second liquid level monitoring unit are provided at the lower inner side of the immersion chamber.

[0011] When the clean water control unit is working, the water level of the clean water temporary storage tank is monitored by the first liquid level monitoring unit. When the water level is lower than the set value, water is added to the clean water temporary storage tank through the pressure variable frequency pump. When the immersion tank needs to be supplied with water, the clean water is heated by the heater, and the clean water temperature at the output end of the heater and the water temperature of the immersion tank are respectively monitored by the first temperature transmitter and the second temperature transmitter.

For example, during the last rinse, the second water quality monitoring unit automatically obtains the conductivity value of the rinse water, and sets the conductivity value within the minimum detection limit required by the pharmaceutical laboratory. Only when the test is qualified can the cleaning be completed. If it is unqualified, two more rinses will be added, and then the test will be carried out, and the cleaning will be determined to be qualified or unqualified based on the test results; when the cleaning is unqualified, a systematic error will be reported to remind the user of possible problems in the entire operation process; the clean water temporary storage tank can be used as a temporary water storage to avoid dry burning of the heater, and at the same time, the water quality of the water source can be monitored.

[0013] When the immersion chamber completes immersion and rinsing of the vessel, regardless of whether the conductivity value of the rinse water reaches the minimum detection limit, the cleaning bracket is separated from the immersion chamber. At this time, the transmission belt reciprocates, and the pressurized clean water is rinsed again for a set number of times through the flushing pipe; among them, when the conductivity value cannot reach the minimum detection limit, the number of reciprocating movements of the transmission belt is doubled; after the flushing is completed, the transmission belt is reset, and then the sampling travel motor drives the gear column to rotate, the gear column engages with the rack, and drives the rack to slide along the inner rail, so that the monitoring slide arm drives the monitoring cabin to reciprocate under the cleaning bracket to collect the rinsed vessels. The dripping liquid of the dish is detected, and the third water quality monitoring unit on the inner side of the sampling cabin is used to monitor in real time whether the dripping liquid reaches the set water quality. If it reaches the set water quality, it is assumed that the cleaning is passed. Otherwise, it is rinsed again through the flushing pipe until the set water quality index is reached, or the flushing pipe reaches the set flushing times, and a cleaning failure alarm message is issued; after completing one test, the drain valve is activated to empty the inside of the monitoring cabin. At the same time, the sampling walking motor is activated to make the monitoring cabin enter under the sampling cleaning pipe, and spray clean water through the sampling cleaning pipe to rinse the monitoring cabin and the third water quality monitoring unit; after the flushing is completed, the cleaning monitoring unit is reset.

[0017] S1: Loading the utensils to be cleaned, inserting the utensils to be cleaned into the through holes in sequence, and elastically pressing the outer parts of the utensils with elastic feet to complete the loading of the utensils;

[0018] S2: The cleaning bracket is loaded, and the flushing unit is pre-activated. The bottom of the square reduced-diameter diversion cavity is closed through the liquid collecting hopper.

[0019] S3: One flushing, the lifting assembly moves, drives the swing arm downward to the bottom of the drying unit, and the pressure variable frequency pump moves to pump the clean water inside the clean water tank to the flushing array. The flushing array performs intermittent pressure flushing on the inside and outside of the vessel. After the flushing is completed and the set time is waited, the transmission belt moves to separate the liquid collecting bucket from the square reduced diameter diversion cavity.

[0020] S4: The cleaning bracket reverses direction, the lifting assembly moves, drives the swing arm downward to the top of the soaking bin, and the transposition motor moves, driving the belt reel and the guide column to rotate synchronously through the transmission belt, thereby driving the frame plate to rotate 90° along the swing arm, so that the cleaning bracket rotates 90°;

[0021] S5: Immersing, the lifting assembly moves, driving the cleaning bracket to completely immerse into the inside of the immersion chamber, turning on the ultrasonic cleaning unit for ultrasonic cleaning, discharging waste liquid through the drain valve, and replenishing water to the immersion chamber through the pressure variable frequency pump, thereby achieving multiple immersions of the vessel;

[0022] S6: End flushing, the lifting assembly moves upward, driving the swing arm upward to the primary flushing position, then the pressure frequency conversion pump operates to pump the clean water inside the clean water tank to the flushing pipe, and the flushing pipe flushes the vessel with the pressurized clean water through the flushing head. At the same time, the transmission belt reciprocates for many times until the reciprocating times are completed, completing the end flushing;
