Description
Technical Field
The utility model belongs to the technical field of the centrifugal separation technique and specifically relates to a cover of disk separator.
Background
Centrifugal separation is a method of liquid-liquid separation and liquid-solid separation by the action of centrifugal force in a liquid-phase heterogeneous system. The butterfly separator is one of the sedimentation type centrifuges, and the separation of materials is realized by utilizing a centrifugal separation technology.
The periphery of the lower part of the rotary drum of the disc separator is provided with a plurality of nozzles, and the material slag is discharged from the nozzles, deposited in the corresponding slag collecting area on the machine cover and discharged out of the separator from the corresponding slag discharge port. The cover of the existing disc separator is shown in figure 1, an inverted bowl-shaped upper shell 2 is fixed above a lower shell 1, a frustum-shaped lower cover 8 is fixed on the inner side of the bottom of the lower shell 1, and a rotary drum 3 is positioned inside the lower shell 1, the upper shell 2 and the lower cover 8; the cross-section that inferior valve 1 stretched into in the epitheca 2 is pressed close to rotary drum 3 for the tip of falling L shape baffle 9, as shown in fig. 2, have clearance 10 between baffle 9 and the rotary drum 3, clearance 10 avoids baffle 9 to interfere the rotary motion of rotary drum 3, form second cavity 12 between rotary drum 3 and the baffle 9, the lower cover 8, form first cavity 11 between rotary drum 3 and the baffle 9, the epitheca 2, be album sediment district 6 between baffle 9 and the inferior valve 1 internal wall, the slag notch 7 has been seted up to corresponding album sediment district 6 on the inferior valve 1, behind the material sediment 13 in the rotary drum 3 discharged from nozzle 5, deposit in album sediment district 6, discharge from slag notch 7. The disc separator rotates in the first cavity 11 in a state of keeping motion due to inertia when the material slag 13 is just discharged from the opening of the nozzle 5 because the rotary drum 3 and the nozzle 5 rotate at a high speed; when a small amount of small particles and light-weight slag particles rotate, under the impact of large-particle heavy-weight particles, a disordered motion state is easy to occur and the slag particles float in disorder in the first cavity 11, and can fall into the second cavity 12 from the gap 10 in the disorder process and deposit on the lower shell 1 and the lower cover 8. Because the second cavity 12 is separated from the slag collecting area 6 and the slag outlet 7 by the partition board 9, the slag 13 deposited on the lower shell 1 and the lower cover 8 can not be discharged through the slag outlet 7 in a centralized way, thereby forming a slag deposition dead angle, the thickness of the slag 13 becomes thicker and thicker as the slag 13 deposited in the slag deposition dead angle accumulates along with the accumulation of the running time of the disc separator, as shown in fig. 1, when the thickness reaches a certain degree, the slag 13 can contact with the lower surface of the rotary drum 3 and rub against the lower surface of the rotary drum 3, which not only can lead the rotary drum 3 to be worn and reduce the service life of the rotary drum 3, but also can lead the rotation speed of the suspension in the rotary drum 3 to be reduced, and the centrifugal force generated by the suspension can be correspondingly reduced, thus leading some solid particles with smaller particles and lighter gravity to not generate enough centrifugal force to deposit on the drum wall of the rotary drum 3, and the solid particles in the suspension can not be sufficiently separated due to the upward movement of the liquid along with the liquid and are discharged from the liquid outlet, so that the solid-liquid separation effect of the separator is influenced.
