Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel sorting equipment, and in particular to a stainless steel sorting machine. Background Technology

[0002] Stainless steel sorting machines are devices used for material screening and sorting, widely applied in industries such as mining, building materials, and chemicals. Their main function is to separate different components in materials through physical or magnetic forces to meet the purity and particle size requirements of industrial production. The use of stainless steel not only enhances the equipment's corrosion resistance and durability but also ensures a clean and efficient sorting process.

[0003] In existing material sorting technologies, fixed screens or vibrating screens are typically used for material screening. During operation, material enters the equipment through the feed inlet and is separated and collected by the fixed screen or vibrating screen, separating materials of different particle sizes. The vibrating screen is driven by a motor to generate vibration, causing the material to move on the screen, thus achieving the screening effect. However, the operation of this equipment is relatively simple, mainly relying on the fixed vibration frequency and amplitude of the screen, making it difficult to flexibly adjust according to the specific conditions of the material.

[0004] In existing technologies, the screening effect of a screen mainly depends on the size of the screen openings and the installation position of the screen. This necessitates frequent screen replacements to adapt to different particle sizes and types of materials. Furthermore, while vibrating screens can improve screening efficiency through vibration, they lack an effective unclogging mechanism when materials clog the screen openings, leading to decreased screening efficiency and even requiring shutdown for cleaning. Therefore, a stainless steel separator is proposed to address these issues. Utility Model Content

The arc-shaped partition plate 13 is used to divide the collection box 11 into two parts, which facilitates the classified collection of sorted materials.

[0034] Working principle: First, connect the power supply to the equipment and pour the material into the top of the feed hopper 5, so that the material is sent into the interior of the outer shell 3 after passing through the feed port. Then start the motor B and the double-head motor 1001. The output shaft of the motor B drives the transmission roller 14 to rotate, and the transmission roller 14 drives the sorting magnetic roller 17 to rotate through the conveyor belt 8.

[0035] Subsequently, the two output shafts of the dual-head motor 1001 drive the rotating rod 1002 to rotate. The rotating rod 1002, through the cooperation of the eccentric wheel 1004 and the eccentric rod 1007, converts the rotational motion into reciprocating motion, which in turn drives the screen plate 16 to swing up and down via the hinge rod 1005 and the slide rod 1006. During the swinging process, the screen plate 16 screens the material, separating materials of different sizes through the screen holes. Larger particles remain on the screen plate 16, while smaller particles fall through the screen holes. The screened material then falls from the outlet of the outer casing 3 into the top of the conveyor belt 8, where it is transported. At this point, the material enters the sorting area, ready for screening and separation.

[0036] The vibration structure 4 between the outer casing 3 and the base frame 2 plays an auxiliary role in the screening process. The connecting piece 401 is elastically connected to the base frame 2 via a spring 402 and slides up and down along the guide rod 403 to generate a vibration effect. This vibration can enhance the movement of materials on the screen plate 16, improve screening efficiency, and prevent material accumulation or clogging of the screen holes.

[0037] When material gets stuck in the gaps of the screen plate 16, the eccentric adjustment structure 18 can be adjusted during machine stop. The specific operating steps are as follows: The operator rotates the knob 1803, which drives the stud 1802 to rotate. The stud 1802, through a threaded connection, drives the threaded sleeve 1203 to move up and down, thereby pushing the eccentric rod 1007 to slide along the slide groove 1801, changing the position of the eccentric rod 1007. The movement of the eccentric rod 1007 increases the swing amplitude of the screen plate 16, allowing the screen plate 16 to cooperate with the unblocking plate 6. The unblocking plate 6 has protrusions that match the screen holes of the screen plate 16, pushing out impurities from the screen holes, preventing material blockage, and ensuring the smooth progress of the screening process.

[0038] In the sorting zone, when the material passes through the sorting magnetic roller 17, the high-frequency alternating strong magnetic field generated on the surface of the magnetic roller will induce eddy currents in the conductive non-ferrous metals. These eddy currents will generate a magnetic field in the opposite direction to the original magnetic field. Non-ferrous metals such as copper and aluminum will be propelled forward along the conveying direction due to the repulsive force of the magnetic field, thus achieving separation from other non-metallic materials and achieving the purpose of sorting.

[0039] After screening and sorting, the materials fall into the collection box 11. The arc-shaped partition plate 13 inside the collection box 11 divides the materials into two parts for easy collection and processing. The motor A1201 is started, and the motor A1201 drives the threaded sleeve 1203 to move through the threaded rod 1202. The threaded sleeve 1203 slides along the limiting rod 1205 through the sliding sleeve 1204, thereby driving the arc-shaped partition plate 13 to move. Finally, the position of the arc-shaped partition plate 13 is adjusted so that the distance between the arc-shaped partition plate 13 and the sorting magnetic roller 17 corresponds to the distance that non-ferrous metals jump due to the magnetic repulsion force. This allows the required non-ferrous metals to fall into the collection box 11 along the arc-shaped partition plate 13, while other non-metallic materials are blocked by the arc-shaped partition plate 13 from falling into the collection box 11, thus achieving the purpose of sorting.

[0040] After sorting is complete, turn off motor B and dual-head motor 1001, stopping the movement of conveyor belt 8 and screen plate 16. Open collection box 11 and remove the sorted material for further processing. Clean the screen plate 16 and the inside of the outer casing 3 of any residual material to prepare for the next use.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
