A shot blasting recovery device and its screening operation method

Abstract

The invention relates to the technical field of intelligent manufacturing, and discloses a shot blasting recovery device and a screening operation method thereof. The shot blasting recovery device comprises a screen box, wherein a guide cylinder is arranged in the screen box; the bottom end of the guide cylinder is fixedly connected with a support rod; the other end of the support rod is fixedly connected to the inner wall of the screen box; an air inlet pipe is arranged at the bottom end of the screen box; the other end of the air inlet pipe communicates with an air outlet of an axial flow fan; a collecting pipe is arranged at the corner of the air inlet pipe; a blocking block is arranged in the collecting pipe; a collecting box is arranged at the top end of the screen box; a push rod movably sleeves one side of the screen box; and a guide plate is fixedly connected to one end, extending into the screen box, of the push rod. According to the shot blasting recovery device and the screening operation method thereof, high-speed air is blown in the air inlet pipe, and according to the different quality of rust, damaged steel shots and intact standard steel shots, the rust and the damaged steel shots are blown into the collecting box to be removed by adopting the wind jacking and screening method, and the intact steel shots are guided into the collecting pipe through the guide plate to complete screening and recycling work.

Description

technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to a shot blasting recovery device and a screening operation method thereof. Background technique [0002] Shot blasting machine refers to the casting equipment that uses the high-speed projectile thrown by the shot blaster to clean or strengthen the surface of the casting. The shot blasting machine can simultaneously shake out sand, remove core and clean the casting. Because it is a treatment technology that utilizes high-speed throwing of steel shots to impact on the surface of material objects, after the derusting and cleaning operation of the shot blasting machine, a large amount of rust will adhere to the surface of the steel shots, which is not conducive to the recycling and reuse of steel shots , and during the cleaning process of the steel shot, the damaged steel shot is not easy to distinguish from the intact and reusable steel shot, which makes the recycl...

Because it is a treatment technology that utilizes high-speed throwing of steel shots to impact on the surface of material objects, after the derusting and cleaning operation of the shot blasting machine, a large amount of rust will adhere to the surface of the steel shots, which is not conducive to the recycling and reuse of steel shots , and during the cleaning process of the steel shot, the damaged steel shot is not easy to distinguish from the intact and reusable steel shot, which makes it difficult to recycle the steel shot. Therefore, a shot blasting recovery device is proposed to solve the above problems
