Automatic powder feeding device of powder bucket

Abstract

The invention discloses an automatic powder feeding device of a powder bucket. The automatic powder feeding device comprises the cylindrical powder bucket and a powder bag containing bucket; a powderbag containing powder is placed in the powder bag containing bucket; the upper part of the powder bucket is connected with one end of a powder suction pipe; the other end of the powder suction pipe stretches into the powder bag; a pneumatic powder suction pump capable of sucking the powder from the powder bag into the powder bucket is arranged on the powder suction pipe; a radar level instrument is arranged at the top of the powder bucket; the distance between the radar level instrument and the interior side wall of the powder bucket is 1 / 6 of the inner diameter of the powder bucket; and the radar level instrument and the pneumatic powder suction pump are connected with a controller. The powder quantity in the powder bucket is monitored in real time through the radar level instrument, andwhen the powder quantity in the powder bucket is less than the set quantity, the controller controls the pneumatic powder suction pump to work to suck a certain amount of powder from the powder bag into the powder bucket, thus automatic feeding of the powder bucket is realized.

Description

technical field [0001] The invention relates to an automatic powder feeding device for a powder barrel. Background technique [0002] The traditional powder supply center adopts the working mode: the powder suction pipe assembly is controlled by the operating mechanism, and the powder is directly extracted from the powder bucket. The powder bucket needs to be fluidized, and the boxed powder needs to be poured into the powder bucket manually. The volume is relatively large, although the frequency of adding powder is reduced, but the powder content in the powder bucket is too much, resulting in uneven fluidization of the powder and easy to be affected by moisture. During the operation of the equipment, due to the large amount of powder in the powder bucket, the fluidization gas must reach a certain level, so the powder is easy to fly, waste powder, and pollute the operating environment. Moreover, with the decrease or increase of the powder in the powder bucket, the fluidizati...

During the operation of the equipment, due to the large amount of powder in the powder bucket, the fluidization gas must reach a certain level, so the powder is easy to fly, waste powder, and pollute the operating environment

Moreover, with the decrease or increase of the powder in the powder bucket, the fluidization situation will change, resulting in the unevenness of the powder during the conveying process, which will affect the spraying effect
