Description
Technical field
The utility model relates to a kind of sedimeter, refers to the filter plant utilizing the waste liquid of principle of negative pressure to lens grinding to process especially.
Background technology
Lens is made up of glass or plastic material usually, and the waste particle that glass material processing produces is large, and proportion is large (>=2.54g/cm3) also, usually uses the precipitation method or centrifugal process process; The lens kind of plastic material is more, comprise heat cured material if CR39 resin lens (proportion is about 1.32g/cm3), thermoplastic material are as PC eyeglass (proportion is about 1.21g/cm3), the waste residue light specific gravity of these materials after grinding, particle is little, if use the precipitation method or centrifugal process process, efficiency is very low, and treatment effect is not good yet.
The existing grinding waste liquid major part of domestic lens is directly discharge, and fraction employs the processing mode such as the precipitation method and centrifugal process.Waste liquid normally concentrates in a waste liquid pool by the precipitation method, after the natural sedimentation of certain hour, takes the clean liquid on upper strata away, then clears up the residue of lower floor.Also containing more tiny granulated slag in the clean liquid taken away.Namely centrifugal process is utilize centrifuge to accelerate sedimentation and filtration principle, solid phase granulated slag is accelerated the technology of precipitate and separate.This method for treating waste liquid must need to use centrifuge core, generally need to use the parts such as variable-frequency motor, frequency converter, centrifugal turning barrel, granulated slag gathering-device, safety insurance mechanism, frame for movement and control circuit more complicated, cost is high, price is relatively expensive, needs periodic maintenance.Meanwhile, if the high flow needed in continuous seepage will be ensured, its filterability all lower (<85%).Therefore research and develop a kind of lens grinding industry that is suitable for, filter with low cost replaces directly discharge and traditional filtering mode and becomes very necessary.
