Description

Non-resistance slag discharging structure of centrifugal machine

Technical Field

The utility model relates to the field of machinery, in particular to a component of a centrifugal machine.

Background

The slag is discharged from the slag outlet along the tangential direction under the action of centrifugal force. When the solid slag content is large, the whole cone drum is filled with viscous solid slag, the viscous solid slag is gathered at a solid slag discharge port to form a bulk state under the pushing of a spiral, so that the viscous solid slag cannot be continuously discharged under the action of centrifugal force but is discharged intermittently, at this time, the bulk viscous solid slag is extruded forwards until the solid slag is extruded to the end face of a small end cover and returned again, the slag discharge resistance is further increased due to the interaction of the returned viscous solid slag and the forward extruded slag, and the slag discharge amount of the centrifugal machine is influenced, so that the processing capacity of the centrifugal machine is reduced.

In addition, the slag hole abrasion-resistant tile and the slag hole abrasion-resistant lining board of the existing centrifugal machine are arranged on the cone rotary drum. When the wear-resisting tile of the slag hole is damaged due to the unreliability in the running process of the centrifugal machine, the conical rotary drum stainless steel body is difficult to repair and severely worn when solid slag passes, and finally the conical rotary drum with higher replacement value is caused, so that the use and maintenance cost is greatly increased.

As shown in fig. 1, the non-resistance slag discharging structure of the centrifugal machine comprises a conical rotary drum 1 and a small end cover shaft 4, wherein the small end cover shaft 4 comprises a disc-shaped shaft cover and a bulge which is arranged at the outer edge of the shaft cover in a surrounding manner, and one end of the bulge, which is far away from the shaft cover, is propped against the end face of the conical rotary drum 1; an opening structure surrounded by the shaft cover, the bulge and the cone rotary drum 1 is used as a slag outlet; the shaft cover is provided with an inward first recess 6 at a position corresponding to the slag hole, the first recess 6 extends along the axial direction of the small end cover shaft 4, and the first recess 6 is communicated with the slag hole. The utility model is to slag from tangential and axial directions, so when the solid slag content is large, the whole cone drum 1 is filled with viscous solid slag, the viscous solid slag gathers and forms a lump at the solid slag discharge port under the pushing of the screw to generate the bridging effect, but because the small end cover shaft 4 is not blocked but is provided with the first concave 6, the lump viscous solid slag is discharged from the first concave 6 under the pushing and pressing of the screw without the phenomenon of slag returning, thereby slag discharge is smoother and continuous, the normal slag discharge amount of the centrifuge is not influenced, thereby improving the processing capacity of the centrifuge, solving the problems of large slag discharge resistance and discontinuous slag discharge of the conventional centrifuge when the viscous solid slag is processed, and improving the processing capacity of the centrifuge under the same working condition. The radial cross section of the first recess 6 is arc-shaped with an opening facing outwards. Thereby reducing the resistance of solid slag discharge. The inner surface of the first recess 6 is deposited with a cemented carbide wear layer. To increase the wear resistance thereof.

The wear-resistant tile 3 is provided with a bolt hole, and the wear-resistant tile 3 is fixed on the bulge through a bolt. The utility model solves the problem that when the abrasion-resistant tile 3 is damaged due to the unreliability of the existing centrifuge in operation, the whole cone drum 1 is replaced with high cost due to the abrasion of the stainless steel body of the cone drum 1. The wear-resistant tile 3 is arranged on the small end cover shaft 4, so that the cost for replacing the small end cover shaft 4 is greatly lower than the cost for replacing the cone rotary drum 1 in the prior art during replacement, and the use and maintenance cost of a user is saved.

As shown in fig. 2, the prior art wear-resistant lining plate 2 is fastened to the sidewall of the tap hole by screws, but leaks out into the tap hole, resulting in a reduction in the actual caliber of the tap hole. As shown in fig. 1, the cone drum 1 is provided with a second recess 5 at the slag outlet, and the second recess 5 is internally provided with a wear-resistant lining plate 2. So that the wear-resistant lining plate 2 is not leaked outside the slag hole.
