Discharging device of expanded perlite

Abstract

The invention provides a discharging device of expanded perlite. The discharging device comprises a telescopic cylinder and a hopper, the telescopic cylinder is welded to the side end of the hopper, the telescopic cylinder is fixed at the lower end of a cover plate, a rotating disc is arranged at the upper end of the cover plate, a rotating shaft is fixed in the middle of the lower end of the rotating disc, the rotating shaft is arranged at the lower end of the cover plate through a bearing and penetrates through the cover plate and is connected with the rotating disc, the rotating shaft is fixed in the middle of the upper end of a sealing plug, and spiral blades are fixed at the lower end of the sealing plug. According to the discharging device, the raw materials in the hopper can be stirred, the blockage phenomenon in the hopper can be effectively prevented, the hopper is sealed through the cover plate and the sealing plug, the dustproof function is effectively achieved, and residualmaterials in the hopper can be effectively prevented from being discharged into the expansion equipment, the device is convenient to use, the use effect is improved, and the functionality is increased.

Description

technical field [0001] The invention relates to a feeding device for expanded perlite, which belongs to the technical field of expanded perlite production. Background technique [0002] Expanded perlite is a kind of natural acidic vitreous volcanic lava, non-metallic minerals, including perlite, pitch rock and obsidian, the three are just different in crystal water content. Because its volume rapidly expands 4-30 times under the high temperature condition of 1000-1300 ℃, it is collectively called expanded perlite. Existing majority utilizes the puffing furnace to carry out production, utilizes unloading device to put raw material into the puffing furnace to carry out production at this moment. [0003] The existing feeding devices for expanded perlite are all simple hoppers. When the hoppers are working, the pipes are often blocked, which affects the use effect. When the hoppers are not working, dust often falls in the hoppers, which affects the next use. Contents of the ...
