In addition, I saw Baidu know that "oilfield settling tank" is an oilfield settling tank and "sewage tank" is a sewage tank. This translation should be wrong, because it is impossible to find the corresponding information according to such keywords. According to the information I have collected so far, there is no doubt that the "settling tank" is a clarification tank (this information is obtained from the patent design network). Then, "? "Sewage tank" should be "separation tank" (this is the information obtained from the website of professional machinery manufacturers).
Also, you can find many structural drawings with the names of various components on them by searching for pictures with the keywords of clarifier and septic tank, which should also be used.
1. Clarifier (sedimentation tank): method and equipment for separating solid particles from liquid. A preferred embodiment includes a tank for precipitating particles from a fluid, a conical chamber at the bottom of the tank, an outlet connected to the conical chamber, and a conical auger in the conical chamber. The tank may have a tangential inlet that creates a fluid circulation that exerts a centrifugal force on the solid particles to increase the sedimentation of the particles from the fluid. There can be static spiral on the inner wall of the tank, which helps small particles to agglomerate into larger particles and precipitate out of the fluid more quickly. The fluid content of solids discharged from the tank can be controlled by changing the rotating speed of the conical auger. The rotating speed of the conical auger can be changed according to the torque required to rotate the conical auger.
2. Septic tank installation system (this is a statement, which should be good)

8. Separate tank attachment (this is a PDF document, and you can also choose to browse the HTML page without a PDF reader).
Comprises (a) a tank, (b) an oil-water inlet device, (c) a flow direction device connected to the oil-water inlet device to guide the oil-water emulsion into a settling tank tangential to the tank wall, (d) a water outlet pipe at the bottom center and (e) an oil outlet pipe.
10. Analyze the equipment status during oil field exploitation (this is only a rough data).
