Description

Technical Field

[0001] This utility model relates to the field of vacuum filter technology, specifically to a vacuum drain tank with cleaning holes. Background Technology

[0002] In many industrial production sectors, especially in chemical, pharmaceutical, and food processing industries, it is often necessary to separate mixtures containing gases and liquids and promptly discharge the separated liquid while maintaining a vacuum environment within the system to ensure the stability of the production process and product quality. Vacuum drain tanks, as a key piece of equipment, are widely used in these scenarios to achieve gas-liquid separation and liquid discharge.

[0003] Chinese patent CN206837544U discloses an automatic vacuum drain tank, which achieves fully automated operation under vacuum conditions and automatic draining through a float level gauge and solenoid valve control, thereby improving work efficiency. Chinese patent CN105879472B discloses an improved energy-saving automatic vacuum balancing drain tank, which places the outlet pipe inside the drain tank, occupying less space. Its observation mirror is easily replaceable, and it features an adjustable intermediate adjustment plate as an observation scale standard. Current improvements in existing technologies mainly focus on the automatic draining settings of vacuum drain tanks, with very little attention paid to the cleaning and maintenance of these tanks.

[0004] During production, materials may deposit and scale on the inner wall, bottom, and some internal structures of the tank. Over time, these deposits can affect the performance of the drain tank, reduce gas-liquid separation efficiency, and even cause problems such as blockage of the drain port. Traditional drain tanks typically lack properly designed cleaning ports, requiring operators to disassemble numerous parts for cleaning, consuming significant time and manpower, increasing equipment downtime, and reducing production efficiency.
