Description

Technical Field

[0001] The invention belongs to the technical field of steel shot screening equipment, and in particular relates to a steel shot screening device and a use method thereof. Background Art

[0002] Steel shot is made of high-quality steel scraps. First, it is melted and the molten steel is formed into small balls by high-pressure water jet. The formed balls are heated again to purify and homogenize, and then quenched. The quenched balls are dried in the furnace and reheated and tempered to achieve appropriate hardness. The tempered steel shots are sorted into 11 grades that meet SAE standards through a mechanical screen for use in shot blasting equipment. The size of the steel shots produced needs to be screened during the production process. In the prior art, when steel shots are screened, a steel shot screening device such as a vibrating screen is generally used for screening. During screening, the mesh size of the screen gradually decreases from top to bottom, so that larger steel shots are screened to the upper layer. This method is feasible for steel shots with fewer specifications, but for steel shots of various specifications to be separated, one steel shot specification requires one screen, resulting in the overall height of the entire equipment being too high. Due to the large vibration during the screening process, if multiple screening nets work at the same time, the impact on the equipment is very large, resulting in the reliability of the equipment cannot be guaranteed. If each screen works alone, the overall efficiency is very low, and the top screen is not easy to roll between steel shots due to the large variety and overall number of steel shots. The screen holes of the top screen are easily blocked, and various specifications of steel shots may eventually appear in the top screen.

[0003] The authorization announcement number CN221311376U discloses a cylinder head steel shot screening device, including a box body, a feed funnel is fixedly connected to the top surface of the box body, and a screening device is arranged inside the box body. The screening device includes a power unit, and the power unit includes a double-headed motor, a screen plate, a mounting plate, a slide bar, a top block and a connecting plate. The cylinder head steel shot screening device is provided with a screen plate, a reciprocating screw, a bevel gear, a double-headed motor, a slider, a connecting plate, a slide bar, a limit block, a top block and a mounting plate, and the double-headed motor is started, and the two bevel gears are used to drive the reciprocating screw to rotate, so that the connecting plate moves to the upper left, so that the top block lifts the steel shot with a slightly larger diameter stuck inside the first sieve hole, so that the steel shot with a larger diameter is discharged from the box body to the left; by providing a screen drum, a spiral blade, a feed pipe and a funnel, the left output shaft of the double-headed motor drives the screen drum to rotate, so that the steel shot with a smaller diameter passes through the second sieve hole and falls to the bottom of the box body, and the steel shot with a smaller diameter is screened out. However, the utility model can only screen steel shots of two specifications, and when steel shots with a larger diameter contain steel shots with a smaller diameter, screening cannot be performed again. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a steel shot screening device and a method of use, which divides the steel shot size into sections according to specifications, with three steel shots in each section, and quickly separates the steel balls of each section by using the existing vibration screen, and then uses the invented steel shot screening device to quickly and accurately separate the steel shots in each section, which effectively solves the problem that when screening steel shots in the prior art, a steel shot screening device such as a vibration screen is generally used for screening. During screening, the mesh size of the screen gradually decreases from top to bottom, so that larger steel shots are screened to the upper layer. This method is suitable for steel shots with fewer specifications. The steel shots are manipulable, but for various specifications of steel shots to be separated, one steel shot specification needs to correspond to one screen, which makes the overall height of the entire equipment too high. Due to the large vibration during the screening process, if multiple screening nets work at the same time, the impact on the equipment is very large, resulting in the reliability of the equipment cannot be guaranteed. If each screen works alone, the overall efficiency is very low, and the top screen is too large in variety and total number of steel shots, so it is not easy for the steel shots to roll between each other, and the top screen is prone to blockage of the sieve holes, and various specifications of steel shots may eventually appear in the top screen.
