Abstract

The invention discloses a vertical type scraper centrifugal device for pulverized coal. The vertical type scraper centrifugal device comprises a dewatering device, a transmission device and a lubricating device, wherein the dewatering device comprises a sieve bucket, a scraper and a cloth cone, the scraper and the sieve bucket are combined, the transmission device is composed of a triangular belt and a bevel gear, and the lubricating device, the dewatering device and the transmission device are combined. The vertical type scraper centrifugal device for pulverized coal is small in vibration, stable in movement, simple in structure, stable and reliable, and high in production efficiency.

Description

Technical field [0001] The invention relates to the technical field of coal preparation, in particular to a vertical scraper centrifugal device for fine coal. Background technique [0002] Coal preparation is mainly based on the difference between the physical and chemical properties of coal and gangue. The impurity in the raw coal is removed mechanically in the coal preparation plant, and it is divided into products of different quality and specifications to meet the needs of different users. Claim. The coal preparation methods are mainly divided into wet coal preparation and dry coal preparation. Wet coal preparation mainly adopts water preparation. Because wet coal preparation encounters high moisture content of coal, sludge is serious, and there are freezing problems in high-cold areas. Dry coal preparation can avoid the above contradictions. As a necessary supplement to wet coal preparation, dry coal preparation has simple technology, low investment, low production cost, le...
