Steel shot sorting device

Abstract

The invention relates to the technical field of steel shot production, and discloses a steel shot sorting device. The steel shot sorting device comprises a shell, a feeding hopper and a discharging pipe. The shell is divided by a supporting frame into an upper cavity and a lower cavity. Screens are arranged at the bottom of the upper cavity, the hole diameter of meshes is sequentially reduced fromthe feeding pipe direction to the discharging pipe direction, and the upper ends, in the steel shot feeding direction, of the meshes are connected with hard balls. A plurality of collecting frames are arranged in the lower cavity, and a material collecting frame is arranged between every two adjacent collecting frames. An intermittent magnet material sucking mechanism is arranged between every two adjacent screens, wherein a material sucking pipe is arranged between the intermittent magnet material sucking mechanism and the next adjacent screen, the lower end of the material sucking pipe penetrates the supporting frame and communicates with the bottom of the corresponding material collecting frame. The material collecting frames are located in front of the intermittent magnet material sucking mechanism, the side wall of the part, located on the upper cavity, of the material sucking pipe is connected with a spraying pipe, the spraying pipe is connected with an induced draft fan, and the free end of the spraying pipe faces the next screen. According to the steel shot sorting device, large steel shots are prevented from blocking the meshes by changing the motion direction of the large steel shots, and small steel shots conveniently pass through the meshes.

Description

technical field [0001] The invention relates to the technical field of steel shot production, in particular to a steel shot sorting device. Background technique [0002] Steel shot is a kind of spherical particle made of special material through special heat treatment. In the preparation process of steel shot, the equipment generally used is a centrifuge, which melts the high-carbon steel and pours it into the rotating centrifugal brick, and then relies on the centrifugal force of the centrifuge to throw out steel shots of various sizes. The discharged steel shot will fall into the quenching pool for rapid cooling, and the rapidly cooled steel shot will be reheated and tempered, so that the steel shot can reach the required hardness. However, due to the different sizes of the produced steel shots, in order to adapt to various types of uses, it is necessary to screen and classify the sizes of the steel shots. At present, when steel shot is screened, steel shot screening mac...

Problems solved by technology

Generally, the mesh hole of the larger mesh screen will be smaller than the diameter of the larger steel shot. If it is blocked, the steel shot with smaller size cannot pass through the mesh and carry out the next screening work, which affects the continuous operation of the screening work, thus making the screening efficiency lower and unable to meet the screening of large quantities of steel shots
