Ship-shaped sugarcane ash hanging type salvage pit elevator and sugarcane ash treatment method

Abstract

The invention discloses a ship-shaped sugarcane ash hanging type salvage pit elevator and a sugarcane ash treatment method. The ship-shaped sugarcane ash hanging type salvage pit elevator mainly comprises an elevator shell, and a bucket chain group is mounted on a head part and a tail part end to end and is driven by a driving unit. An unloading wheel is arranged in the head part close to a head shaft, and when the bucket chain group passes through the unloading wheel, a strong polygon effect is generated. A lifting section shell comprises a shell body, a first concave groove is formed in the lower portion of the shell body, and a scraper type hopper and the first concave groove form a 'drawer' type hopper. A settling mechanism is mounted in a horizontal soaking section shell and presses sugarcane ash into water. The tail part comprises a hanging type salvage pit box body and a tail part assembly. The tail part assembly is fixed above the hanging type salvage pit box body, and the bucket chain group is wound onto a tail wheel, is naturally bent by virtue of self weight and is isolated from the hanging type salvage pit box body. According to the ship-shaped sugarcane ash hanging type salvage pit elevator and the sugarcane ash treatment method, settlement of sugarcane ash, ash-water separation lifting and discharging can be rapidly completed.

Description

technical field [0001] The invention relates to a hoist, in particular to a boat-shaped sugarcane ash hanging type pit hoist and a sugarcane ash processing method. Background technique [0002] The by-product of sugarcane juice extraction is bagasse, which can be used as fuel for biomass power plants. After the bagasse is burned, the main waste discharged from the boiler for power generation is sugarcane ash. The temperature of the cane ash as it exits the boiler is around 900 degrees. Due to the high temperature, it needs to be cooled before being sent out through the conveyor. Due to the relatively large volume of sugarcane ash and the low specific gravity of bagasse (the specific gravity of sugarcane ash is 0.2-0.3t / m3), the existing cooling method generally adopts water sealing to cool down. [0003] In the prior art, the processing method of sugar cane ash has: [0004] ①. Use water flushing. The sugarcane ash that is about to be cooled is transported to the cane as...

Problems solved by technology

However, this treatment method does not meet the environmental protection requirements and has been banned.

[0005] ②. The sugar factory in French Guiana used to use a belt conveyor to transport sugarcane ash, but because the sugarcane ash was suspended in the water, it did not move with the belt and the driving roller slipped, so it could not be used normally, so it had to be dismantled

The sugarcane ash soaked in cooling water sticks into agglomerates, which is easy to block the pores, resulting in the inability to separate water and ash, so it is excluded

[0007] Bucket elevators were excluded due to their greater susceptibility to overload, fragile hoppers and traction elements and inability to separate water and ash

[0008] At present, there is no precedent for using other types of conveyors (such as belt conveyors, buried scraper conveyors, etc.) to transport sugarcane ash in China
