Bulk material silo cutter tooth unloader

Abstract

The invention relates to a cutter teeth discharging machine of a bulk material silo, which is characterized in that: a slewer is arranged right above a discharging hopper on the bottom of the silo; the slewer is a slewing tray frame slewing around a central shaft; one side of the edge of the slewing disk is provided with a set of hydraulic driving system while the other side thereof is provided with a rotary cutterhead with a speed reduction motor; the cutterhead is provided with one to six cutter teeth and the working surface of the cutter teeth is provided with scrapers; an decompression cone which is used for preventing the material from arching and is supported on the wall of the silo is arranged in the silo right above the slewer. By adopting the discharging machine, whether single-cutter discharging or multi-cutter discharging is adopted can be determined according to storage amount of the bulk material and the size of the silo. The discharging machine has the advantages of flexible layout position of the silo, small labor load for maintenance and environmental protection.

Description

A bulk material silo cutter tooth unloader technical field The invention relates to an unloader, and in particular discloses a silo cutter-tooth unloader that can be used for bulk material silo storage, which is widely applicable to the unloading of bulk material silo storage in electric power, steel, chemical, cement and other industries , especially the unloading of desulfurized gypsum silos (bulk materials with about 10% water content) in thermal power plants. Background technique At present, there is no device of the present invention in China for the unloader of bulk materials stored in silos. The following describes the unloading of a desulfurized gypsum silo (bulk material with a water content of about 10%) in a thermal power plant. The desulfurized gypsum produced by wet desulfurization in thermal power plants contains about 10% water, and when the gypsum is dehydrated abnormally, it is as high as 13% to 15%. At present, except for a few that use silos for stora...

AI Technical Summary

Problems solved by technology

The main problems are as follows: ① Even though the grab buckets are used to equalize the material and the conveyor belt is used for multi-point unloading, the actual effect is very poor, or even useless, which greatly reduces the storage capacity

② The gypsum warehouse needs to consider the entry and exit of transport vehicles, which will undoubtedly increase the floor area of ​​the gypsum warehouse

③When the output of desulfurized gypsum is large, the operating rate of forklifts is too high, making it difficult to ensure timely transportation

④ Desulfurization gypsum is highly viscous and causes sticking, especially when the water content is high, which brings difficulties to normal operation, management and maintenance

⑤ Due to the frequent entry and exit of transport vehicles into and out of the gypsum warehouse, the gypsum scattered on the ground pollutes the environment
