AI Technical Summary
Existing manual sampling methods for coal tar have problems such as poor sample representativeness, low work efficiency, and significant health and safety risks to personnel.
By linking the loading valve with the electronic signal valve and combining it with the controller to precisely control the sampling timing and flow rate, and by using a rotary automatic drum changing mechanism, the entire coal tar sampling process is automated, ensuring constant sampling timing and sample representativeness, reducing manual operation and minimizing personnel contact time.
It improves the automation level and sample representativeness of coal tar sampling, significantly enhances sampling efficiency, effectively reduces personnel health and safety risks, and ensures safe operation in flammable and explosive environments.
