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

technical field [0001] The invention relates to an unloading machine, and in particular discloses a silo cutter tooth unloading machine which can be used for bulk material silo storage, and is widely applicable to the unloading of bulk material silo storage in industries such as electric power, steel, chemical industry, cement, etc. , especially the unloading of desulfurization gypsum silos (bulk materials with a water content of about 10%) in thermal power plants. Background technique [0002] At present, the unloading machine of the bulk material stored in the silo does not have the equipment of the present invention in China. The following is an illustration of the unloading of the desulfurization gypsum silo (bulk material with a water content of about 10%) in a thermal power plant. [0003] The desulfurization gypsum produced by wet desulfurization in thermal power plants has a water content of about 10%, and when the dehydration of gypsum is abnormal, it can reach as ...

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
