Roller conveying apparatus with solid-liquid separation function

Abstract

The invention relates to a roller conveyer device for metallurgical slag materials. The roller conveyer device with a solid-liquid separation function comprises an internal spiral roller, a feed funnel and a sealing-supporting device, wherein the sealing-supporting device connects the rotating internal spiral roller with the static feed funnel into a whole; the internal spiral roller and the feedfunnel are arranged in a V shape, and the internal spiral roller has an included angle with the horizontal plane; the periphery of the internal spiral roller is sleeved with a shaft sleeve capable ofrotating together with the internal spiral roller; the shaft sleeve is arranged inside the sealing-supporting device; the shaft sleeve is shaped like a Chinese character 'tu'; one end and the peripheral surface of the shaft sleeve are in sliding contact with the sealing-supporting device; one end of the sealing-supporting device is fixed with a discharge hole of the feed funnel; the roller is driven to rotate by a driving device; the inner wall of the roller is fixed with at least one continuous spiral blade. The roller conveyer device can convey solid particles to a certain height and realize solid-liquid separation, is good in sealing effect, and can eliminate steam overflow caused by materials.

Description

Roller conveying device with solid-liquid separation function technical field The invention relates to a roller conveying device for metallurgical slag. Background technique Compared with other metallurgical slag treatment technologies, the drum method metallurgical slag treatment technology has the advantages of short process, less investment, safety and reliability, low energy consumption, direct utilization of treated slag, and less pollution. It has been gradually recognized and rapidly promoted by the industry. For the transportation of the slag discharged from the drum device, the chain conveyor is currently used to transport the material to the slag yard. Since the discharge of the drum is a mixture of slag and water, a large amount of fine slag will flow from the chain conveyor along with the water. The flow out from the gap of the chain plate causes a large amount of slag accumulation in the lower part of the chain plate machine, which will not only bring a lot of...
