Description

Light-duty centrifuge

Technical field

Light-duty centrifuge is that grease, medicine, chemical industry are made a kind of new type processing equipment in the Separation of Solid and Liquid processing technology.

Background technology

At present, the heavy type structures that adopt in the centrifuge industry more, consumption material, power consumption, cost height are paid wages too much the user, and are adopted stability light-duty, the small-power centrifugation apparatus poor.

Summary of the invention

The utility model is provided with the central flat step in rotary drum [4] bottom, makees central tumbler with the motor of repacking, is situated between in the motor lower end pole coil [20] is housed; Friction price fixing [21], motor blower fan [22] are gone up the dress wearing piece, become the friction deceleration device; Overcome rotating inertia force, can shut down in required time, simultaneously available artificial braking; The motor bearings upper and lower side is equipped with oil sealing [17 28 31 33], prevents that lubricating oil runs off, lower bearing assembling angular contact ball bearing [18]; Centrifuge is welded into A-frame with section bar, and light saving material can make the rotary drum off-centre power of shaking obtain balance.

Specific embodiments

A kind of light-duty centrifuge is directly made central tumbler with improved motor.Triangle supporting plate ［ 11 ］ connects A-frame with suspension rod screw ［ 40 ］, spring ［ 41 ］, bearing ［ 38 ］.Spring is contained between the force of triangle supporting plate and A-frame, plays cushioning effect, can make the off-centre power of shaking of rotary drum obtain balance.Rotor cover, motor are connected on the triangle supporting plate with bolt ［ 34 ］.Top cover connects shell with snap close ［ 36 ］, and rotary drum [4] is used the opened type U-shaped, and bore is suitable, is convenient to get slag.Fluid flows out from housing outlet [35], and slag takes out from the closure head mouth.Meshed around a kind of rotary drum, lean on drum rotating to produce centrifugal force, fluid is discharged from mesh, around slag is stored in the drum.Do not have mesh around a kind of rotary drum, fluid goes out from rotary drum benefit suitable for reading, and slag leans on around centrifugal force is stored in the drum, during shutdown fluid in the drum down orifice flow go out, above the rotary drum blade ［ 3 ］ is housed, utilize windchill.Motor after the improvement is a vertical machine, and spindle nose stretches to the top, and cover flange by dress, is a kind of motor that can bear pressure at right angle with the eccentric power of shaking of rotary drum at the top.Substitute centrifuge central authorities tumbler, reduced configuration, the electricity consumption power is little, has practiced thrift the energy.Motor is thickeied casing on the basis of national design standard, the motor shaft overstriking, and bearing strengthens, and spindle nose is a pyramid type, connects rotary drum [4] with clutch [8].The clutch top is a platform, and rotary drum [4] is contained on the platform, tightens on spindle nose with dome sieve cap [6].Can make centralized positioning accurate.Centrifuge motor bottom end cover dress angular contact ball bearing [18].Can bear pressure at right angle and the off-centre power of shaking.The bearing upper and lower side is equipped with oil sealing [17,28,31,33], and lubricating oil is not run off.Because rotary drum [4] inertia force is big, downtime is oversize.Below the motor lower end is situated between [19], magnetic pole dish ［ 20 ］ is housed, coil is contained in the magnetic pole dish, and grinding disk [21] is situated between with the lower end with spring with location sieve bolt and is connected, and is the friction price fixing.Friction plate is equipped with in fan blade ［ 22 ］ top, as Moving plate, is connected with sieve silk ［ 23 ］ with spindle nose under the motor, can adjust frictional resistance.Produce magnetic attraction during energising, the magnetic pole dish holds friction price fixing [21], and price fixing overcomes spring dress power and draws close the magnetic pole dish on Jie of lower end, and motor rotates.During outage, the friction price fixing leans on spring dress power to contact with friction plate on the fan blade [22], produces lighter frictional resistance, makes the rotating speed reduction, can shut down in required time.Motor shaft mounted under the balance wheel [25]? And brake Dai [26],? Also available artificial brake.
