Description

A kind of disk centrifugal separator from damping

Technical field

The utility model relates to a kind of butterfly centrifugal machines from damping.

Background technique

The rotary drum of existing disk centrifugal separator when rotating at high speed, be easy to happen rotary drum rotation center offset the phenomenon that.

If current most widely used disk centrifugal separator include main support, motor, rotary drum, the main shaft inside rotary drum and The dry dirty dish of receiving being set on main shaft, the motor are connected by transmission parts with rotary drum, and sump oil is equipped with below the rotary drum Entrance, the upper end of the rotary drum be successively arranged from top to bottom light liquid outlet and heavy liquid exit, centrifuge sump oil entrance is entered Sump oil be centrifuged, after mixed liquor flows out feed pipe, the reason of because of centrifugal force, the every of mixed liquor can be inverse toward top Stream.

Because of the density contrast reason of mixed liquor items, the solid phase of weight can gravity be more than centrifuge be start to stay down and by It is thrown on the inner wall of rotatory drum wall and takes advantage of a situation and flow to slag-drip opening, the heavier oil water mixture of specific gravity can be arranged through the heavy liquid exit on machine Out, and the lighter liquid phase of specific gravity or oily item can continue ' soaring ' along disk until from the light liquid of machine upper end outlet discharge, but Existing centrifuge does not often have the ability of damping.

Utility model content

It is strong, anti-bias that purpose of the utility model is to solve the deficiencies of the above prior art and provide a kind of cushioning abilities The butterfly centrifugal machine from damping of the heart.

A kind of disk centrifugal separator from damping, including main support, motor, rotary drum, the main shaft inside rotary drum and several A dirty dish of receiving being set on main shaft, the rotary drum are connected to the motor by transmission parts, the bottom of the drum be equipped with sump oil into Pipe, the top of the rotary drum is equipped with light liquid outlet and heavy liquid exit, the axle journal section of the rotary drum upper section and the axle journal section of lower section are each It is connected by a shock absorber with main support, the shock absorber includes bearing, the inner ring being connected with bearing outer ring and outer ring and master The connected outer ring of bracket, the inner ring of the bearing are connected with the axle journal section of rotary drum, pass through three between the inner ring and outer ring It is connected in the spring of 120 ° of horizontal distributions.

Inner and outer rings, which are got rusty, in order to prevent causes shock absorber to fail, and assigns inner and outer ring certain elastic deformability, described Inner and outer rings material be brass.

In order to prevent when high speed rotation, bearing damage, the bearing is high speed and precision bearing.

Liquid is irregular in order to prevent, and anchor formula agitating paddle, and the anchor formula agitating paddle position are also arranged on the main shaft Inside rotary drum.

Preferably, the transmission parts are belt pulley, and the belt pulley is set on rotary drum outer wall.

Preferably, the rotary drum is die casting.

The utility model has the advantages that

The rotary drum fixed form of existing disk centrifugal separator is that Hard link will result in so eccentric phenomena once occurs The strong vibration of device.And the utility model use shock absorber connection type, especially three horizontal positioned spring structures, It can allow rotary drum that being eccentrically rotated for certain angle occurs, and this is eccentrically rotated and can be offset by the deformation of spring, so whole Device will not shake.

In actual use, often due to internal liquid center of gravity unevenness the small rotation less than 1 ° can occur for rotary drum, and Shock absorber in the utility model shakes for the rotation of minute angle, has good cushioning effect.

Detailed description of the invention

Fig. 1 is the schematic diagram of the utility model；

Fig. 2 is the schematic diagram of shock absorber in the utility model；

1. 2. rotary drum of main support, 3. main shaft 4. receives dirty 5. light liquid of dish outlet 6. heavy liquid exit, 7. shock absorber, 8. bearing 9. 12. anchor formula agitating paddle of inner ring 10. outer ring, 11. spring, 13. belt pulley.

Specific embodiment

In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further It is described in detail, which is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.

A kind of disk centrifugal separator from damping, including main support 1, motor (not shown), rotary drum 2, be set to rotary drum in The main shaft 3 in portion is set in the dirty dish 4 of receiving on main shaft with several, and the rotary drum 2 is connected to the motor by belt pulley 13, described Belt pulley 13 is set on 2 outer wall of rotary drum, and 2 bottom of rotary drum is equipped with sump oil inlet pipe, and the top of the rotary drum goes out equipped with light liquid Mouth 5 and heavy liquid exit 6, the axle journal section of 2 upper section of rotary drum and the axle journal section of lower section respectively pass through a shock absorber 7 and main support phase Even, the shock absorber includes the outer ring 10 that bearing 8, the inner ring being connected with bearing outer ring 9 and outer ring are connected with main support, described The inner ring of bearing 8 is connected with the axle journal section of rotary drum, and passing through three between the inner ring 9 and outer ring 10 is in 120 ° of horizontal distributions Spring 11 is connected, and the inner and outer rings material is brass, and the bearing 8 is high speed and precision bearing.

Anchor formula agitating paddle 12 is also arranged on the main shaft, and the anchor formula agitating paddle 12 is located inside rotary drum 2.

The rotary drum 2 is die casting.

Working condition:

When the liquid center of gravity in rotary drum 2 is not overlapped with the initial axis of rotary drum 2, small rotation can occur for rotary drum 2 at this time (less than 1 °), the small rotation are offset by the deformation of spring 11, the vibration of single unit system can be effectively reduced, to improve Service life of device.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
