Description
Technical field
The present invention is a kind of improvement structure of horizontal helico-centrifuger upper-part, specifically relates to a kind of improvement structure of thin oil lubrication bearing support of decanter centrifuge.
Background technique
When the horizontal helico-centrifuger main bearing uses thin oil lubricant, under the not smooth condition of fuel feeding, guarantee that still bearing can be in lubricating status, this is because be provided with the oil storage ring in bearing support inside, but the accumulated impurity gradually through the bottom of oil storage ring after a while, when impurities accumulation can rise to a certain extent, can touch bearing, can damage bearing, cause bearing life to reduce.
Existing countermeasure is, when 1 year left and right sides time, centrifuge carried out light maintenance, open centrifuge principal axis bearing loam cake, take out main shaft, the impurity that accumulates in the oil storage ring is got rid of, for this kind situation following 2 deficiencies are arranged: 1. the Environmental Conditions of centrifuge itself is more abominable, running about a year, the thickness that is stored in impurity in the oil storage ring has surpassed bearing outer ring, bearing has been caused certain infringement, although this infringement and not serious, often this causes centrifuge to work thereby the performance that causes centrifuge working life that must reduce bearing reduces more serious meeting in the past.2. the accuracy of manufacturing of the Hough face of centrifuge principal axis bearing is higher, the number of times that bearing support is opened increase the accuracy of manufacturing that will inevitably affect the Hough face, often this in the past the accuracy of manufacturing of Hough face must descend, thereby can cause the appearance of the phenomenon of bearing support leakage of oil.To above problem, no matter be to repair, change, all need to stop work, affect working efficiency, produce very large economic loss, add that concrete, direct component are revised the economic loss of changing larger, related domain is eager to have a good technological scheme to be changed, and improves.
Summary of the invention
The present invention intends providing a kind of deslagging device for thin oil lubrication bearing support of decanter centrifuge, has both avoided manner of cleaning up of the prior art, and the disadvantage of bringing thus, can guarantee timely scarfing cinder simultaneously, and bearing is in all the time cleaning, moves under the operating mode of slag less.
The objective of the invention is so to realize.
A kind of deslagging device for thin oil lubrication bearing support of decanter centrifuge, the one or both sides, front and back that are fixed on bearing support by the annular metal sheet of crescent shape evagination form the oil storage ring, it is characterized in that:
Offer a runoff notch in the bottom of oil storage ring, offer a through hole at a left or right sidepiece of lower of bearing support, metal bar of configuration in through hole, metal bar is a straight-bar and end one annulus;
The annulus of metal bar is positioned at the outside of through hole, and the inner padding of metal bar straight-bar is in the runoff notch bottom;
One prominent ring is set at the nearly annulus of the straight-bar of metal bar place, configuration one spring between prominent ring and annulus, the straight-bar of metal bar, prominent ring and spring all insert in the through hole, and an end of spring props up prominent ring, and the other end props up the through hole outer side wall.
Further, the through hole on lower of the described bearing support is cylindrical hole, is bolted the configuration sealing mat in the through hole outside of lower of bearing support, and sealing mat is that its left and right halves merges and forms.
Further, the through hole on lower of the described bearing support is cylindrical hole, is bolted the configuration sealing mat in the through hole outside of lower of bearing support, and sealing mat is the monoblock pad, and described annulus is connected with the straight-bar outer end threadably.
Further, the through hole left or that a right sidepiece is offered that described bearing support is lower is shoulder hole, and outer side wall is aperture, and described annulus is connected with the straight-bar outer end threadably.
Further, described metal bar is stainless steel.
Adopt the technical program, offer corresponding through hole in bearing base side and oil storage ring bottom, in the machine operation, the runoff notch that metal bar and oil storage ring leave fits tightly.When machine is shut down after operation after a while; annulus on the metal bar can be pulled outwardly; thereby open the runoff notch of oil storage ring bottom; impurity flows back to hydraulic station after flowing into the bearing support bottom and the lubricant oil of bearing support bottom mixes by runoff notch, and impurity is removed by crossing filter core in hydraulic station.After impurity racks up, unclamp annulus, metal bar resets because of the elasticity of spring, thereby the runoff notch of oil storage ring bottom is sealed again.
Advantage of the present invention and beneficial effect could be removed the impurity in the oil storage ring when 1. need not by the time centrifuge light maintenance or overhaul, can not overflow across bearing outer ring to guarantee the impurity that accumulates in the oil storage ring, and bearing is caused damage, and have improved the working life of bearing; 2. reduce and avoid causing because of removal of contamination the damage of Hough face, guaranteed the bearing support reliability of operation; 3. easy spring reverse motion, thus having guaranteed that stainless steel bar behind removal of contamination resets reaches the disabler that can not cause because of personal factor the oil storage ring; 4. the part cost of greatly having saved bearing wear, repairing that bearing support Hough face damages, replacing with and delay the expense of equipment operation.5. the technical program is simple in structure, and it is convenient to implement, and cost is low, has very large application value.
