Description

Technical Field

[0001] This utility model relates to the field of scrap steel recycling technology, specifically to an online automatic purification device for scrap steel crushed material. Background Technology

[0002] Scrap steel refers to steel scrap that is not used as a product during the steelmaking process (such as trimmed edges and cut ends), as well as steel materials from scrapped equipment and components. Scrap steel composed of steel is called scrap steel; scrap iron composed of pig iron is called scrap iron. Both are collectively referred to as scrap steel. After being crushed by a crusher, scrap steel becomes shredded scrap of a certain size. Generally, before being transferred from the crusher to the conveyor belt, the shredded scrap steel undergoes air separation to remove light impurities.

[0003] An existing patent application (CN 202220731105.4) discloses an online automatic purification device for scrap steel shreds. This device uses an exhaust fan in conjunction with the central shaft of a dust collection hood and a rake cylinder to remove light impurities such as lint and cloth from the scrap steel shreds, thereby improving the purity of the scrap steel shreds. However, the exhaust fan is insufficient to effectively remove these light impurities, resulting in incomplete cleaning. Furthermore, larger pieces of scrap steel shreds are prone to jamming when passing through the rake cylinder, affecting its usability.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0005] To address the above deficiencies, this utility model provides an online automatic purification device for scrap steel crushing materials to solve the problem of cleaning light impurities from scrap steel crushing materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An online automatic purification device for scrap steel shreds includes a conveying mounting frame and a combustion chamber installed on the upper end of the conveying mounting frame.

[0009] Furthermore, the conveying mechanism includes a drive motor, a stainless steel conveyor belt, a reciprocating screw, a reciprocating screw nut, a connecting rod, and a material-pulling claw. The drive motor is horizontally mounted on the left side of the front end of the conveying mounting frame. The stainless steel conveyor belt is movably mounted inside the conveying mounting frame, and the drive roller of the stainless steel conveyor belt is connected to the rotating end of the drive motor. The reciprocating screw is movably inserted into the center of the combustion chamber. The reciprocating screw nut is movably fitted onto the reciprocating screw. The connecting rod is mounted at the bottom of the reciprocating screw nut, and the material-pulling claw is mounted at the bottom of the connecting rod.

[0014] This utility model provides an online automatic purification device for scrap steel crushed material, which has the following beneficial effects: a conveying mechanism is provided in the conveying installation frame, and a stainless steel conveying mesh belt is used to convey scrap steel crushed material. At the same time, the reciprocating screw drives the material-pulling claw to move back and forth, which moves the scrap steel crushed material on the stainless steel conveying mesh belt, so as to facilitate the complete combustion treatment of light impurities in the scrap steel crushed material.

[0015] The combustion mechanism uses several flame nozzles on two sets of mounting rods to burn off light impurities in the scrap steel. It is combined with an electric push rod to drive two sets of swing rods to swing back and forth, thereby increasing the combustion area of ​​the flame nozzles and effectively removing light impurities from the scrap steel.
