Description: An oil vacuum sewage cabin bottom water receiving device, which belongs to the ship sewage treatment and environmental protection. This oil cabin background vacuum sewage water in the receiving apparatus using the two vacuum water tank connected in parallel, the electronic control unit based on the detected level meter level signal to control the solenoid valve is opened to allow compressed air to open the corresponding pneumatic valve, to ensure When a vacuum water tank evacuated and water, another vacuum water tank through the air and drainage. Since the two vacuum water tank can alternately cited drainage, drainage work continuously to make the lead, the entire water discharge process without any mechanical agitation, avoiding secondary bilge water emulsified in the transport process. The vacuum receiver with low investment and low power consumption, stable and reliable, high efficiency and easy maintenance management.
