Oil separation grit chamber used under hand washing sink

Abstract

The invention discloses an oil separation grit chamber used under a hand washing sink, and belongs to the field of environmental protection. Partition plates are fixedly arranged on the inner walls of two opposite side plates in a box body of the oil separation grit chamber, a channel is formed between the lower edges of the partition plates and a bottom plate of the box body, the partition plates divide the box body into a treatment area and a clear water area, an outlet of a drain pipe of the hand washing sink is arranged at one end of the treatment area of the water tank, a communicating pipe is arranged on the side wall at the outlet of the drain pipe, one end of the communicating pipe is connected to a bottom plate of a hollow cylinder, the communicating pipe is communicated with the middle of the cylinder, a top plate of the cylinder is provided with an opening, a floating ball is arranged in the cylinder, a connecting rod is fixed at the upper end of the floating ball, a flexible conical indicator is arranged at the upper end of the connecting rod, and a water outlet pipe vertically penetrates through the bottom plate of the box body in the clear water area. When particulate matters settled in the oil separation grit chamber reach the designed maximum quantity, the indicator always protrudes out of the cylinder, so that a user can conveniently observe the indicator in time and clean impurities in the box body in time.

Description

technical field [0001] The invention relates to an oil-separating grit chamber, in particular to an oil-separating grit chamber used under a wash basin. Background technique [0002] In industrial enterprises, front-line operators in manufacturing, hardware, mould, auto repair, mines, oil fields, machinery, printing and other related industries will have "black hands". , sand and other solid particles in the production process. In the sink, use a special cleaning agent for cleaning, and some cleaning agents are not soluble in water. Therefore, the sewage generated in the sink contains oil, a small amount of iron filings, sand and other solid particles in the production process. Such sewage needs to be treated in oil-separating sedimentation tanks to avoid blocking subsequent municipal pipelines. [0003] In view of the problems referred to above, the existing oil separation sedimentation tank is arranged on the open space below the hand washing sink. The drainpipe of the ...

AI Technical Summary

Problems solved by technology

Since the oil-separating sedimentation tank is directly below the sink, it is difficult for the user to observe the situation in the tank when washing hands, and the height of the sediment in the tank cannot be judged intuitively, so it cannot be cleaned in time

This results in more sediment in the pool, the effective filtration volume in the pool is further reduced, the residence time of sewage in the pool is greatly shortened, the effect of sedimentation and oil separation is not good, and some solid particles and oil will be discharged from the outlet pipe of the sedimentation tank, resulting in Effluent water quality is not up to standard
