[0002] In traditional chemical laboratories, dyes are usually purified by water extraction to remove the acidic substances. This process is currently mainly completed by manual operation in China. The specific steps include:

[0003] Workers pour the product to be purified into a pear-shaped funnel.

[0004] Add water in batches and seal the pear-shaped bottle with a stopper.

[0005] The pear-shaped funnel is shaken vigorously manually to allow the product to fully react with water for extraction and purification.

[0064] Step 2: After the equipment is turned on, it is necessary to reset the equipment. The waste water pipe on the turntable assembly rotates to the bottom of the funnel assembly driven by the motor. The equipment reaches the initial position and the startup conditions are met.

[0065] Step 3: According to the stock liquid to be processed, open the corresponding solenoid valve, the first three-way solenoid valve, the first gear pump and the second three-way solenoid valve in the PTFE exhaust valve assembly, and open the outlet solenoid valve and the fifth three-way solenoid valve under the funnel at the same time.

After a certain amount of water is delivered, close the first three-way solenoid valve, the first gear pump and the second three-way solenoid valve corresponding to the cleaning agent, open the outlet solenoid valve, and discharge the water into the waste water bucket.

[0071] Step 9: Clean the funnel with cleaning agent, open the third three-way solenoid valve, the second gear pump and the fourth three-way solenoid valve corresponding to the cleaning agent, close the outlet solenoid valve, and deliver the cleaning agent into the funnel. After a certain amount, close the third three-way solenoid valve, the second gear pump and the fourth three-way solenoid valve corresponding to the cleaning agent, open the outlet solenoid valve, and discharge the cleaning agent liquid into the waste water bucket;

[0072] Step 10, clean the funnel with water, open the third three-way solenoid valve, the second gear pump and the fourth three-way solenoid valve corresponding to water, close the outlet solenoid valve, and transport water into the funnel. After a certain amount, close the third three-way solenoid valve, the second gear pump and the fourth three-way solenoid valve corresponding to the cleaning agent, and open the outlet solenoid valve; discharge the water into the waste water bucket.

After receiving the completion signal, the PLC controls the outlet solenoid valve (414) ) is opened to discharge the water out of the funnel (412), the visual component (45) continues to take pictures to identify whether the water in the lower layer is drained, and the water is collected in the waste water bucket (36) below the rotating disk; after the water is drained, the outlet electromagnetic valve (414) is closed, the rotating disk rotates, the collection bottle (503) rotates to the bottom of the liquid outlet (4124) of the funnel (412), the outlet electromagnetic valve (414) is opened, the washed liquid is collected in the collection bottle (503), and then the outlet electromagnetic valve (414) is closed; Step 7: The cleaning agent cleans the upper stock liquid pipeline, opens the cleaning valve, the first three-way solenoid valve (321), the first gear pump (331) and the second three-way solenoid valve (322) corresponding to the cleaning agent, closes the outlet solenoid valve (414), and delivers the cleaning agent to the funnel (412). After a certain amount, closes the first three-way solenoid valve (321), the first gear pump (331) and the second three-way solenoid valve (322) corresponding to the cleaning agent, opens the outlet solenoid valve (414), and discharges the cleaning agent liquid into the waste water bucket (36); Step 8: Clean the upper stock liquid pipeline with water, open the water valve, the first three-way solenoid valve (321), the first gear pump (331) and the second three-way solenoid valve (322) corresponding to the water, close the outlet solenoid valve (414), and transport the water into the funnel (412). After a certain amount of water is transported, close the first three-way solenoid valve (321), the first gear pump (331) and the second three-way solenoid valve (322) corresponding to the cleaning agent, open the outlet solenoid valve (414), and discharge the water into the waste water bucket (36); Step 9, the cleaning agent is used to clean the funnel (412), the third three-way solenoid valve (323), the second gear pump (332) and the fourth three-way solenoid valve (324) corresponding to the cleaning agent are opened, the outlet solenoid valve (414) is closed, and the cleaning agent is transported into the funnel (412). After a certain amount of cleaning agent is transported, the third three-way solenoid valve (323), the second gear pump (332) and the fourth three-way solenoid valve (324) corresponding to the cleaning agent are closed, and the outlet solenoid valve (414) is opened to discharge the cleaning agent liquid into the waste water bucket (36); Step 10, clean the funnel (412) with water, open the third three-way solenoid valve (323), the second gear pump (332) and the fourth three-way solenoid valve (324) corresponding to the water, close the outlet solenoid valve (414), and transport the water into the funnel (412). After a certain amount of water is transported, close the third three-way solenoid valve (323), the second gear pump (332) and the fourth three-way solenoid valve (324) corresponding to the cleaning agent, and open the outlet solenoid valve (414); discharge the water into the waste water bucket (36).
