Abstract
The utility model relates to the field of a centrifuge in the machine industry, and particularly relates to an improved structure of a liquid blocking plate on the end surface of a rotating drum of a horizontal decanter centrifuge, which comprises a plurality of water outlet holes (5) which are arranged on the end surface of a rotating drum (4) at a large-end flange of the horizontal decanter centrifuge, and a liquid blocking plate (3) which is fixed at the outer side of the water outlet holes (5) on the end surface of the rotating drum (4) through screws, and is characterized in that: a buffering hopper (2) which presents in a semi-cup shape in the longitudinal direction and has an opening facing outwards is respectively fixed at the inner side of each water outlet hole (5) on the end surface of the rotating drum (4). The buffering hoppers (2) are fixed on the end surface of the rotating drum (4) in a welding way. The buffering hoppers with the semi-cup shape in the longitudinal direction and the opening facing outwards slow down and block water which floods and penetrates from the water outlet holes, so surplus water is prevented from being discharged from a clear liquid water outlet to abrade and rust a main bearing, and the defects influencing the service life of the bearing and the running of the centrifuge are overcome.
Description
Technical field
The utility model relates to the centrifuge field of mechanical industry, specifically is a kind of structure-improved of Drum of Horizontal Screw Centrifuge Based end face lip ring structure.
Background technology
Known, horizontal spiral centrifuge is the density contrast that relies on the solid-liquid two-phase, and under action of centrifugal force, the sinking speed of accelerating solid phase particles realizes the separation machinery of Separation of Solid and Liquid.Along with the needs of environmental protection in modern age, disposal of three wastes development, for all raisings gradually of requirement of industrial wastewater and sludge dewatering treatment.Because it is very fast that therefore characteristics such as the unique continued operation of horizontal screw centrifuge, treating capacity is big, adaptability is strong develop.
In horizontal screw centrifuge, after mud is sent into rotary drum by the sewage sludge feed pipe, under the centrifugal action that rotation produces at a high speed, changed in the rotary drum chamber immediately.Mud granule is because proportion is bigger, and centrifugal force is also big, and therefore quilt is got rid of and is attached on the drum inner wall, forms solid layer; Therefore moisture can only be called the pendular ring layer at the inboard liquid level that forms of solid circular layer because density is less, and centrifugal force is little.Gu the mud of circular layer is under the slow promotion of auger conveyor, the slag notch that is transported to the little end flanges of rotary drum is discharged continuously, and the liquid of liquid phase layer is discharged by the liquid outlet on the big end flanges.
Horizontal screw centrifuge has been offered some on the rotary drum end face at big end flanges place, be generally four apopores, end face at rotary drum, lip ring has been fixed by screw in the outside at apopore, lip ring can be regulated the position that hides apopore, effect is to regulate the inner liquid level of rotary drum, can carry out adjusting to a certain degree simultaneously to the flow of apopore.Because the structure of centrifuge is limit; distance between general rotary drum and the case is all closer; cavity volume between case and the rotary drum is less; when shutting down because of the gravity effect; water on the rotatory drum wall falls and adds that the water of discharging from liquid outlet causes instantaneous delivery excessive; have little time to discharge from purified liquor outlet, unnecessary water will ooze out from case and rotary drum slit.
The water capacity that the big end of rotary drum spills is easily infiltrated in the base bearing, owing to contain impurity in the water, thus cause bearing wear to get rusty, influence the operation of bearing life and centrifuge.So finding out a kind of method of leaking that prevents is very important.
On the basis of former lip ring; buffering bucket of position welding of apopore; the water of discharging from liquid outlet can directly not be flushed on the case; a water part that flows down from rotatory drum wall during shutdown also can flow into buffering bucket; with regard to being not easy to appear at the situation that a large amount of water has little time to discharge when shutting down, can well improve the phenomenon that seeps water in case and rotary drum slit like this.
Summary of the invention
The purpose of this utility model provides a kind of structure-improved of lip ring on the Drum of Horizontal Screw Centrifuge Based end face apopore, to prevent and to slow down water in the rotary drum in the instantaneous situation that pours out, leaks out to base bearing of stopped status.
The purpose of this utility model is achieved by following technical scheme:
A kind of lip ring structure-improved of horizontal screw centrifuge comprises some apopores that the big end flanges of horizontal screw centrifuge place rotary drum end face is offered, and at the end face of rotary drum, the lip ring in that the outside of apopore is fixed by screw is characterized in that:
At the end face of rotary drum, fixedly be respectively in the inboard of each apopore vertical half cup-shaped, opening buffering bucket toward the outer side.
Further, described buffering bucket is fixed on the end face of rotary drum with welding manner.
Further, described apopore is four.
Inboard as herein described, the outside mean that relatively from the axis of rotary drum be the center, and what point to axis on end face be the inboard, the reverse direction periphery be the outside.
On the basis of former lip ring; buffering bucket of position welding of apopore; the water of discharging from liquid outlet can directly not be flushed on the case; a water part that flows down from rotatory drum wall during shutdown also can flow into buffering bucket; with regard to being not easy to appear at the situation that a large amount of water has little time to discharge when shutting down, can well improve the phenomenon that seeps water in case and rotary drum slit like this.
The beneficial effects of the utility model are, be vertical half cup-shaped, opening buffering bucket toward the outer side slows down and has stopped the water of outwards gushing out and oozing out from apopore, has prevented that the unnecessary water of clear liquid delivery port discharge from getting rusty to the wearing and tearing of base bearing, influences the defective of the operation of bearing life and centrifuge.

Among the figure, the 1st, case, the 2nd, buffering bucket, the 3rd, lip ring, the 4th, rotary drum, the 5th, apopore, the 6th, auger conveyor.
The specific embodiment
Further describe structure of the present utility model below in conjunction with accompanying drawing.
A kind of lip ring structure-improved of horizontal screw centrifuge, comprise some apopores 5 that the big end flanges of horizontal screw centrifuge place rotary drum 4 end faces are offered, end face at rotary drum 4, the lip ring of fixing by screw in the outside of apopore 53, end face at rotary drum 4, fixedly be respectively in the inboard of each apopore 5 vertical half cup-shaped, opening buffering bucket 2 toward the outer side.Vertical half cup-shaped openings buffering bucket 2 toward the outer side is fixed on the inboard of apopore 5, when clear liquid water is gone out from delivery port 5, can stop that the long-pending part of containing is dripped by buffering bucket 2, non-leakage to the bearing place, the openings of sizes that does not influence 3 pairs of apopores 5 of former lip ring is again regulated.
Described buffering bucket 2 is fixed on the end face of rotary drum 4 with welding manner.On the metal end face of rotary drum 4,, not only save trouble but also firm with the fixing buffering bucket 2 of welding manner.
Described apopore 5 is four.On rotary drum 4 end faces of common horizontal screw centrifuge, offer four apopores 5 and be advisable, can satisfy the water outlet needs substantially, therefore, also dispose four buffering buckets 2 for suitable at the end face of rotary drum 4.
