Description

Technical Field

[0001] This application relates to the technical field of catheter cleaning, and particularly to a catheter cleaning process and device. Background Art

[0002] After the catheter is processed, welding oil stains will adhere to the surface or inside of the catheter. The welding oil stains will affect the subsequent processing quality of the catheter. Therefore, it is necessary to clean the catheter after welding.

[0003] The catheter is an irregular, curved body with a certain length. Generally, gasoline is used to wipe the outer surface during cleaning, and the inner wall of the catheter is cleaned by flushing and then dried naturally. Gasoline wiping has poor safety. The efficiency of using a single flushing method for the inner wall is low, and the cleaning quality is difficult to guarantee. Natural drying has a long drying cycle. When cleaning parts, ultrasonic waves are generally used for cleaning. When using ultrasonic cleaning, the parts are placed in an ultrasonic cleaning tank. The ultrasonic generator generates high-frequency high voltage, which is conducted to the transducer through a cable connection line. The transducer and the vibrating plate generate high-frequency resonance together, so that the solvent in the cleaning tank can wash the dirt under the action of ultrasonic waves.

[0004] In view of the above related technologies, due to the different lengths of the catheters, it is difficult for the ultrasonic cleaning system to clean the inside of the catheters thoroughly when cleaning the catheters. Especially for longer catheters, manual operation is still required to clean the inner and outer walls of a single catheter step by step during cleaning. The cleaning steps are relatively cumbersome, time-consuming and laborious, and the cleaning quality is difficult to guarantee. The cleaning method is difficult to meet the needs of large-scale production of catheters. Summary of the Invention

[0005] In order to facilitate the cleaning of catheters and improve the efficiency and effect of catheter cleaning, this application provides a catheter cleaning process and device.

[0006] The catheter cleaning process and device provided by this application adopt the following technical solutions:

[0008] S1. Perform cleaning treatment on the processed catheter, and the cleaning treatment uses an ultrasonic cleaning system;

[0009] S11. A fixing component is placed in the ultrasonic cleaning system. When performing rough cleaning, the catheter to be cleaned is installed on the fixing component. After the installation is completed, the catheter is placed in the ultrasonic cleaning system for cleaning;

[0010] S2. After rough cleaning, transfer the fixing component and the catheter to a combined cleaning machine, and the combined cleaning machine can perform rinsing treatment on the catheter after rough cleaning;

[0011] S21. The cleaning liquid enters the ultrasonic cleaning system through a pump and after degassing. A liquid level sensor is installed inside, and it automatically stops when reaching the liquid level.

[0012] S22. During the rinsing process, first, the catheter is ultrasonically cleaned again.

[0013] S23. After ultrasonic cleaning, the inner wall of the catheter is rinsed under high pressure with the cleaning liquid.

[0014] S24. After internal rinsing, the cleaning liquid in the combined cleaning machine is drained, and the catheter is dried with hot air to dry the inner and outer walls of the catheter.

[0015] S3. Take out the cleaned catheter and recycle the cleaning liquid after rough cleaning and rinsing. The cleaned hydrocarbon solvent is regularly recycled through a distillation recovery machine for reuse.

[0016] By adopting the above technical solution, after rough cleaning the catheter, it is rinsed again. During the rinsing process, the inside of the pipeline is rinsed and air-dried. Before rough cleaning the catheter, multiple catheters are installed on the fixing component, which is convenient for transferring the catheter after rough cleaning, thus facilitating the cleaning of the catheter and improving the efficiency and effect of catheter cleaning. After cleaning, the cleaning liquid is recycled, improving the utilization rate of the cleaning liquid.

[0017] Optionally, the ultrasonic cleaning system includes a first cleaning tank, a lifting plate and a lifting drive arranged inside the first cleaning tank. The lifting drive is connected to the lifting plate and is used to drive the lifting plate to lift and lower inside the first cleaning tank. A first fixing plate is provided on the lifting plate, and the first fixing plate is used to install the fixing component.

[0018] By adopting the above technical solution, when rough cleaning the catheter, start the lifting drive. The lifting drive drives the lifting plate to rise, install the catheter on the fixing component, and fix the fixing component on the first fixing plate, thereby fixing the catheter on the lifting plate. The first fixing plate improves the stability of the fixing component and the catheter inside the first cleaning tank. Start the lifting drive, and the lifting drive drives the lifting plate to descend until the fixing component together with the catheter enters the first cleaning tank, and then start the ultrasonic cleaning system to ultrasonically clean the catheter.

[0019] Optionally, when rough cleaning the catheter in step 2, by repeatedly driving the lifting drive, the lifting drive drives the lifting member to move up and down reciprocally, performing the lifting and tossing function to realize the flushing and cleaning function of the cleaning liquid.

When the conduit is installed on the plug rod, the limiting plate is placed between the conduit and the fixing strip, and the locking bolts are used to press against the limiting plate. While the locking bolts press against the limiting plate, the limiting plate presses against the conduit, reducing the possibility of the conduit shaking during the reciprocating rough washing of the up and down movement.

[0025] Optionally, the combined cleaning machine includes a second cleaning tank and a liquid washing pump provided in the second cleaning tank. A second fixing plate is provided in the second cleaning tank. A plurality of second slots are formed in the second fixing plate. The arrangement of the plurality of second slots is the same as that of the first slots. The plug rod can be inserted into the second slots. Cleaning ports are formed in the second slots.

Start the liquid washing pump. The liquid washing pump drives the cleaning liquid in the second cleaning tank into the conduit to clean the inside of the conduit. After cleaning the inside of the conduit, the cleaning liquid is discharged. Start the air pump and use the air pump to blow air into the conduit to dry the inside of the conduit, improving the cleanliness of the inside of the conduit while saving time and facilitating subsequent processing of the conduit.

[0027] Optionally, the mounting head is a quick-release joint.

[0030] By adopting the above technical solution, the cooler can cool down the cleaning liquid in the first cleaning tank and the second cleaning tank.

[0031] Optionally, vacuum degassing devices are provided on both the first cleaning tank and the second cleaning tank.

[0032] By adopting the above technical solution, the vacuum degassing device can degas the cleaning liquid, enabling the cleaning liquid to smoothly enter the conduit holes.

[0033] Optionally, the second cleaning tank is provided with a conduit inner wall flushing and cleaning device.

[0034] By adopting the above technical solution, the flushing and cleaning device can perform high-pressure cleaning on the inner wall of the conduit, improving the cleanliness of the inner wall of the conduit.

After rough cleaning, the fixing component together with the pipeline is moved to the combined cleaning machine, and the combined cleaning machine cleans the inside of the conduit and air-dries the inside of the conduit after cleaning. The combined cleaning machine can improve the cleanliness of the conduit while increasing the air-drying speed of the conduit, thus facilitating the cleaning of the conduit and improving the efficiency and effect of conduit cleaning, and facilitating subsequent conduit processing procedures;

[0041] 2. Set a second fixed plate, and set a cleaning port on the second fixed plate. A cleaning port is set on the insertion rod. When the insertion rod is inserted into the second slot, the cleaning port communicates with the cleaning port. At this time, when it is necessary to clean the inside of the conduit, start the liquid washing pump. The liquid washing pump pressurizes and transports the cleaning liquid into the conduit to scour and clean the inside of the conduit.
