The powder quantitative air-conveying dosing device of claim 7, wherein: the fastening component comprises a sliding rod and a limiting block, the two limiting blocks are connected to the sliding rod in a sliding mode, the two ends of the sliding rod are fixed to the bottom plate through screws, so that the limiting blocks are fixedly compressed by the sliding rod, the limiting blocks are fixed to the side wall, opposite to the sliding block, of the limiting block, and slots capable of enabling the limiting columns to be inserted are formed in the sliding block.
9. The use method of the powder quantitative air-conveying and adding equipment is characterized by comprising the following steps of: comprises the following steps of (a) carrying out,
s1, in the primary installation process of the pneumatic feeding equipment, leveling the levelness of the spiral scale, placing the spiral scale at a set position, observing horizontal bubbles on four side walls of the bottom plate, and observing whether bubbles in the horizontal bubbles are in the middle;
s2, when the levelness of the spiral scale is adjusted, the corresponding thread sleeve is rotated to enable the thread sleeve to ascend or descend along the axis direction of the stud so as to adjust the distance between the supporting plate and the bottom plate, so that the integral levelness of the spiral scale is changed, and the spiral scale is kept in a horizontal placing state;
s3, after the air-conveying feeding equipment is installed, materials are continuously fed into the extending hopper through the flexible connection interface and enter the main hopper, the stirring driving assembly drives the stirring assembly to move to stir the materials in the main hopper, the weighing module continuously weighs the materials in the main hopper, the main driving assembly drives the conveying auger to rotate, and the continuously weighed materials are conveyed into the air-locking rotary valve;
s4, conveying the materials in the air locking rotary valve into the Venturi tube and conveying the materials to a required position by air, sucking the dust in the main hopper and the extension hopper into the air locking rotary valve by the dust removal air pipe in the conveying process of the materials in the air locking rotary valve, and conveying the dust out along with the materials in the Venturi tube to form air conveying and feeding;
s5, repeating the steps S3-S4 to continuously weigh and feed.
