Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is elaborated, wherein:
Fig. 1 is the structural representation of the utility model drum centrifugal separator;
Fig. 2 is the structural representation of prior art drum centrifugal separator.
The specific embodiment
The utility model drum centrifugal separator in the applying date be that June 28, application number in 2002 are 02140838.6, the application people be Deng Yanzhong, improvement on the Chinese patent that application is called drum centrifugal separator, mainly to be the center tubular axis be fixedly connected with one between center tubular axis and rotating cylinder shell and the short tube of vertical described center tubular axis at the tubular axis opening part for it.And in order starting conveniently, to be provided with a filling funnel, to be provided with the by-pass valve control of a control filling funnel and center tubular axis break-make between described filling funnel and the center tubular axis at the front end of described center tubular axis.For the material that filling funnel is injected can enter in the machine under the self gravitation effect, the height of filling funnel should be higher than fuselage.
See also Fig. 1, the utility model drum centrifugal separator comprises frame 1, is fixed on center tubular axis 2 motionless on the frame, the center is passed and be supported on the tubular axis of described center by described center tubular axis and can be connected and drive the rotating driving device 4 that rotating cylinder rotates around the rotating cylinder 3 of center tubular axis rotation, with rotating cylinder.Wherein:
Rotating cylinder 3 has a shell 31, and described shell 31 comprises side shell 311 that is positioned at side and the back cover 312 that is positioned at the rear end.Rotating cylinder 3 rear ends are fixedly connected with a rotatable hopper 35 adjacent with back cover 312.Rotatable hopper rotates with rotating cylinder, is used for concentrating sediment, balance rotating cylinder internal pressure.Rotatable hopper 35 is provided with sediment outlet 351 away from the back cover end, and the sediment of concentrating is discharged from the outlet of funnel.The front end of rotating cylinder is provided with one and is used to drive the belt pulley 39 that rotating cylinder rotates.The center of rotating cylinder 3 is passed by center tubular axis 2, rotating cylinder is provided with rotating cylinder blade 32 on the inner surface of side shell 311 front ends, the back cover 312 of rotating cylinder is provided with opening 3121, between back cover 312 and tubular axis opening 24, be provided with an interior bottom 33 that is fixed on the tubular axis of center, and leave the space between interior bottom 33 and the rotating cylinder shell 31, the edge of interior bottom 33 is connected with scraper conveyer 34 along the axial restraint of center tubular axis.
Rotating driving device 4 comprises the controller 42 and the belt 43 that is connected described belt pulley 39 and motor 41 with a motor 41, the described motor 41 of control.Motor rotates under the control of controller 42 and drives belt pulley 39 rotations of rotating cylinder front end by belt transmission, thereby makes rotating cylinder 3 around 2 rotations of center tubular axis.
Center tubular axis 2 is fixedly connected with a short tube 241 between center tubular axis 24 and rotating cylinder shell 31, described short tube 241 vertical described center tubular axis at tubular axis opening 24 places.A half that deducts central shaft outer radius gained difference more than or equal to the rotating cylinder inside radius in the length of short tube can produce enough pressure reduction makes overflow enter the center tubular axis.Because short tube is the same with the center tubular axis not to rotate, an atmospheric pressure that just communicates in the material oar porch of center tubular axis with the external world, and enter short tube mouth place in overflow, because the overflow rotation has produced centrifugal pressure, thereby produce a pressure differential at the short tube two ends, change the pressure that the material oar is sucked the increase of material oar inlet into according to characteristics of liquids, increase along with short tube length, the inside pressure of slip also increases, thereby the slip that is lower than the seat in the plane is entered in the machine, the material oar source that no longer needs to contain the material containing oar is arranged on and is higher than the place, seat in the plane, and is very easy to use, and enlarged the range of application of this drum centrifugal separator.
Because before loom starts, to will fill with water or slip in the machine, could rotate the powerful centrifugal pressure of generation, therefore, the upper front end of center tubular axis 2 is provided with a filling funnel 29, is provided with the by-pass valve control 291 of a control filling funnel and center tubular axis break-make between described filling funnel 29 and the center tubular axis 2.For the material that filling funnel is injected can enter in the machine under the self gravitation effect, the height of filling funnel should be higher than fuselage.The funnel bottom joins with screw thread with the control ball valve.Can open by-pass valve control before starting, injection water or expect oar etc. in the filling funnel, closing control valve again after filling with.
When with filling funnel changing-over delivery device, splash into floating agent, just become the drum-type centrifugal floatation sorting machine of a flash flotation.Replace existing inefficient flotation cell, concentrator, sedimentation basin, filters etc. are doted on large equipment.Reduce and take up an area of, play quick and energy-conservation effect.Adopt the drum-type centrifugal floatation sorting machine, because of this machine has rotating speed, slip control such as time of staying in machine shows, chooses the excellent optimum state that draws operation by debugging.For the water body of handling chemical contamination, can from delivery device, splash into harmless and can with the material of harmful components generation chemical reaction in the water, generate insoluble sediment, can remove harmful components by this machine.
Center tubular axis 2 is provided with ball valve 28 and excess flow meter 26 at overflow outlet duct 22 places, is provided with material oar flowmeter 27 at material oar 21 places that enter the mouth.Ball valve 28 is used to adjust the spillway discharge of rear end, and the spillway discharge of rear end should be consistent with material oar flow and material oar volumetric concentration result of calculation, when inconsistent, by the operation ball valve, makes it reach consistent.
During work, start the front opening by-pass valve control, in filling funnel, inject water or expect oar etc., closing control valve again after filling with.The suction in tubular axis that produces in short tube pressure at two ends difference because overflow is rotated, the material oar enters from material oar inlet, enter the front end of rotating cylinder through diffluence pass, the rotating cylinder blade acceleration that is used to quicken to expect oar through the setting of rotating cylinder inside sidewalls front end, the overflow that separates tubular axis opening of rear end in the rotating cylinder enters the center tubular axis, and discharges through the overflow outlet duct of rear end.And be deposited in sediment on the rotating cylinder inwall, discharge rotating cylinder by the arc opening of the gap around scraper conveyer, the interior bottom, back cover and the outlet of rotatable hopper.
The utility model is by the design of short tube, be equivalent in machine, increase slip driver part from front to back, utilized simple structure can make the utility model centrifugal separator be higher than the slip source and be no more than an atmospheric pressure and also can use with interior lowland for about 10 meters high for the seat in the plane.The utility model especially is suitable for Separation of Solid and Liquid and as the flash centrifugal floatation sorting machine of mining industry flotation, to the key player on a team, anti-choosing can both be suitable for.
