Drawings

FIG. 1 is a schematic view of a discharge apparatus according to the present utility model;

wherein:

1-a material tank; 2-a transmission pipe; 3-a spiral stirrer; 4-a pulverizer; 5, a material collecting bag; 6, an overhaul port; 7-connecting pipe.

Detailed Description

The utility model will now be described in detail with reference to the drawings and examples.

Referring to fig. 1, a material tank overhauling and shutdown unloading device comprises a material tank 1, a transmission pipe 2 and a pulverizer 4 which are sequentially communicated; the bottom of the transmission pipe 2 is provided with an access hole 6.

The material tank 1 is of a bucket-shaped structure with an upper cylinder and a lower cone.

The conveying pipe 2 is provided with a material inlet and a material outlet communicated with the material inlet, the conveying pipe 2 is internally provided with a spiral stirrer 3, the axial direction of the spiral stirrer 3 is the same as that of the conveying pipe 2, and the material inlet is communicated with the material outlet through the spiral stirrer 3. The material inlet is communicated with the material tank 1, and the material outlet is communicated with the pulverizer 4; the access opening 6 is arranged between the material inlet and the material outlet.
