According to the acid concentration, substances, suspended solids, other impurities and water purification requirements, the corresponding measures can be taken, such as: 1.introduction; Chuck is used for clamping workpieces on machine tool mechanical device.Using uniform in jaw chuck body on the activity of radial movement, the workpiece clamping and positioning of the machine tool accessories.Chuck is usually mounted on a lathe, cylindrical grinder and internal grinder, can also be used with different dividing device, used for milling and drilling.
2.classification: count from chuck claw can be divided into: two jaw chuck, three jaw chuck, four jaw chuck, six jaw chuck and special chuck.From the use of power can be divided into: Manual Chuck, pneumatic chuck, hydraulic chuck, electric and mechanical chuck chuck.From the structure can be divided into: hollow chuck and implementing chuck
Our company main produce K11series 3 jaw self-centring chucks and K72series 4 jawindependent chucks
1) Three Jaw Chucks : using uniform on the chuck body three jaw radial movement, the workpiece clamping and positioning of the machine tool accessoriesUse voltaic spanner rotating bevel gear, bevel gear drive plane rectangular thread, and then the three claw centripetal movement, because the plane rectangular thread pitch is equal, so three jaw movement distance is equal, have the effect of the automatic centering.
2) four jaw chucks :With four screw drive respectively four claws, so common four jaw chuck no self-centering effect.The commonly used four jaw chuck, is composed of a plate body, four screw, consisting of a pair of jaw.Work is respectively with four screw drive four claws, four claw is only one single jaw chuck card whole claw.

1. Treatment of acidic water containing iron carbonate and ferric sulfate should be carried out by aeration in a graded gas column, clarification by a horizontal sedimentation tank, or treatment with lime, aeration in a staged mixing tank, coagulation and precipitation. It is also possible to add lime to the vertical mixer and then add a coagulant to the flocculator to clarify.
2. For the treatment of iron-containing acidic water with high suspended solid content, it can be treated with lime, spray aeration, mesh screening, coarse filtration in sand pond, coagulation, sedimentation, filtration and disinfection. Or treatment with lime, spray aeration, mesh screening, sand preprecipitation, electrocoagulation, precipitation, rapid filtration, exposure disinfection.
3. Treating the acidic waste water with different concentrations of, in particular, containing heavy metals and impurities more acidic waste water, the basic substance may be added to the lime, carbide slag, etc., to neutralize the acidic waste water. When lime is introduced, calcium hydroxide has a cohesive effect on wastewater impurities and is a common method. However, this method has poor labor hygiene conditions, difficult operation and management, difficulty in dehydration and high cost.
4. For the acidic sewage with less oil and salt and less acid concentration, the filtration neutralization method can be adopted.
5. If there are two kinds of alkali acid wastewater in a mine, the two kinds of wastewater can be mixed and neutralized. Suitable for treating different concentrations of acid and alkali wastewater.
