Description

Spiral blanking device Technical Field The application relates to the field of screw feeders, in particular to a screw feeder. Background At present, raw mineral soil is subjected to multiple grinding and water grinding procedures, then a proper amount of water, dispersing agents and the like are added for blending and stirring in the processing process of the mineral soil, so that silica or aluminum silicate is formed, and finally the mineral soil is packaged into bags for sale. In the related art, in order to improve the processing efficiency of the ore soil, the whole process of the ore soil is generally utilized to process the ore soil, and raw ore soil sequentially undergoes multiple grinding, water stirring, dispersing agent and the like on the production line to be blended and stirred, so that finished ore soil such as silica soil or aluminum silicate and the like is formed. The end of the production line is provided with a spiral discharging device, the spiral discharging device is connected to a large storage pipe through a negative pressure pipe, when the production line discharges, finished ore soil is conveyed to the spiral discharging device, then the finished ore soil is conveyed to the storage pipe through the negative pressure pipe, a packaging bag is arranged at the lower end of the storage pipe, and the packaging bag is connected with the finished ore soil output by the storage pipe, so that the packaging of the finished ore soil is realized. With the related art, the defect that after the finished ore soil is packaged, some packaged ore soil needs to be reworked for changing the packaging bags due to factors such as customer requirements, packaging bag breakage and the like exists. At this time, as the finished ore and soil are already proportioned and are in closed connection, the finished ore and soil cannot directly enter the spiral discharging device to carry out secondary bagging operation, if the finished ore and soil are proportioned and finished ore and soil are proportioned through an upstream production line of the spiral discharging device, if the finished ore and soil are proportioned and manually changed, labor is consumed, and therefore, the current process of reworking and packaging bag changing of the bagged ore and soil is more troublesome. Disclosure of utility model The application provides a spiral feeder for improving the efficiency of reworking and changing packaging bags by bagged mineral soil.
