Detailed Description

The following describes embodiments with reference to the drawings.

A steel shot circulating system: the steel shots enter the shot blasting device (12) through a shot supply valve (4) arranged on the shot storage box (7) through a hose, form a high-speed steel shot flow after being accelerated by the shot blasting device (12), perform shot blasting and rust removal on the vehicle body, then fall into a pit, roll downwards to the longitudinal spiral conveyor (10) -the transverse spiral conveyor (19) -the bucket elevator (1) -the top spiral conveyor (3) -the shot storage box (7) through the slope steel plate (18).

The flowing direction of the steel shots through the shot-sand separator (5) is as follows: in the conveying process of the top screw conveyor (3), broken steel shots and silt automatically move to the bottom of the top screw conveyor (3), namely a shot supply valve (4) above the shot separator (5), a shot supply pipe (25) of the shot separator (5), pass through a gap below an upper adjusting plate (23), roll down from the left end of a distribution plate (26) onto a lower adjusting plate (21), roll to the left and the lower, enter a shot outlet pipe (34), a shot sliding hose (6), pass through the side wall of a shot blasting chamber (9), roll down to a slope steel plate (18), and enter a shot blasting steel shot circulation system of a truck body for shot blasting.

The separation process of the broken small steel shots and the silt in the shot-sand separator (5) comprises the following steps: broken small steel shots and silt move along with the steel shots in the conveying process of the top screw conveyor (3), the broken small steel shots and silt automatically move to the bottom of the top screw conveyor (3), namely a shot supply valve (4) above the shot-sand separator (5), a shot supply pipe (25) of the shot-sand separator (5), pass through a gap below the upper adjusting plate (23), fall off along with the steel shots from the left end of the distribution plate (26), the broken small steel shots and the silt are wrapped by wind force, drift to the right side along with air from the upper part of the lower adjusting plate (21), and pass through the baffle plate (8), due to the action of gravity, the broken small steel shots and large-particle silt move downwards (air and fine dust enter the ventilation and dust removal system (20) through the exhaust pipe (29) to be treated), namely, the dust outlet pipe (32), the canvas hose (15) and the waste bin (14), and the broken small steel shots and the silt in the waste bin (14) are periodically treated.

Flow direction of air: the ventilation hole (22) -a gap between the distribution plate (26) and the lower adjusting plate (21) -the left side of the baffle plate (8) -the turn-back 180 degrees-the right side of the baffle plate (8) -the exhaust pipe (29) -the exhaust branch pipe (2) -the exhaust main pipe (16) -the ventilation and dust removal system (20).
