Description

Technical Field

[0001] This utility model belongs to the field of scrap steel processing technology, and in particular relates to an automated scrap steel sorting device. Background Technology

[0002] Scrap steel refers to steel waste that does not become a product during the steel production process, as well as steel materials from equipment and components that are scrapped after use. As an important raw material for steel smelting, the sorting efficiency of scrap steel directly affects smelting costs and product quality.

[0003] Traditional vibrating screens rely solely on aperture size for sieving, making it difficult to effectively separate lightweight impurities such as rust and plastic adhering to the surface of scrap steel. This results in impurities being mixed into the smelting process, increasing slag volume and reducing furnace lifespan. Existing sorting devices (such as magnetic separators) have insufficient adsorption capacity for small particles of pulverized scrap steel, causing them to be discharged along with impurities, resulting in resource waste.

[0004] To address these issues, we provide an automated scrap steel sorting device. Utility Model Content

[0005] The purpose of this utility model is to provide an automated scrap steel sorting device. By combining a drum sorting component, a screen sorting component, and a blower, it solves the problem that existing scrap steel sorting devices are unable to effectively separate light impurities such as rust and plastic adhering to the surface of scrap steel, resulting in poor sorting effect and affecting subsequent smelting costs and product quality.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

The roller sorting assembly includes a positioning ring, the top of which is fixedly connected to the top of the inner cavity of the housing, and a sorting roller movably connected to the inner cavity of the positioning ring. An electromagnetic strip is disposed on the inner wall of the sorting roller, a toothed ring is fixedly connected to one side of the surface of the sorting roller, and one end of the sorting roller is fixedly connected to... The device is equipped with a feed cylinder. A drive motor is fixedly connected to the top of one side of the inner cavity of the outer shell. A gear is fixedly connected to the output shaft of the drive motor. The gear meshes with a gear ring. The screen sorting assembly includes a groove. The groove is formed on the inner wall of the outer shell. A fixed rod is fixedly connected to the inner cavity of the groove. A return spring is sleeved on the surface of the fixed rod. A movable part is movably connected to the surface of the fixed rod and between the return springs. A vibration motor is provided at the bottom of the movable part. A buffer spring is fixedly connected to the bottom of the inner cavity of the movable part. A buffer is fixedly connected to the top of the buffer spring. A sorting screen frame is fixedly connected to the top of the buffer. An electromagnetic plate is provided at the bottom of the inner cavity of the sorting screen frame.

[0008] The present invention is further configured such that a telescopic rod is fixedly connected to one side of the bottom of the inner cavity of the outer shell, the top of the telescopic rod is fixedly connected to the bottom of the sorting screen frame, and the telescopic rod contracts and extends as the sorting screen frame shakes, which can support and limit the bottom of one side of the sorting screen frame and improve the shaking stability of the sorting screen frame.

[0009] The present invention is further configured such that a support frame is fixedly connected to the bottom of the outer shell, and a receiving box is movably connected to the inner cavity of the support frame. The support frame with good anti-slip properties can provide stable support for the bottom of the outer shell, and the receiving box movably set in the inner cavity of the support frame can receive the scrap steel sorted out by the sorting screen frame in real time.

[0010] The present invention is further configured such that a feeding hopper is provided on the top of one side of the outer shell, and one side of the feeding hopper is connected to the feeding cylinder. The dust cover on the top of the feeding hopper is opened, and the scrap steel is poured into the feeding hopper. The scrap steel slides down into the sorting roller through the feeding hopper.

[0011] The present invention is further configured such that a fixing frame is fixedly connected to the bottom of one side of the outer shell and below the slag discharge port, and an impurity box is movably connected to the inner cavity of the fixing frame. The impurity box is used to receive rust slag and plastic particles and other scrap steel impurities discharged from the slag discharge port.

[0012] The present invention is further configured such that a limiting groove is formed on one side of the inner cavity of the movable part, and one side of the buffer part is located in the inner cavity of the limiting groove. The one side of the buffer part moves up and down in the inner cavity of the limiting groove.

[0015] 1. This utility model has a high efficiency sorting capability. Through the cooperation of a drive motor, gears and gear rings, the sorting drum is driven to rotate, so that the scrap steel is fully turned over in the drum. The electromagnetic strip can effectively adsorb iron-containing scrap steel, realizing the initial sorting of iron-containing scrap steel. At the same time, the sorting screen frame is also equipped with an electromagnetic plate, which can further adsorb the fine iron-containing scrap steel. The dual electromagnetic adsorption improves the sorting accuracy of iron-containing scrap steel. In addition, the shaking screening function of the sorting screen frame can further screen the scrap steel after the initial sorting by the sorting drum, which can effectively separate scrap steel of different specifications.

[0016] 2. This utility model has good buffering performance. The vibrating motor drives the moving parts to make the sorting screen frame shake up and down. When large pieces of scrap steel fall onto the sorting screen frame, the buffer spring can effectively buffer the impact force, reduce the degree of structural deformation of the sorting screen frame due to impact, and enhance the durability of the equipment. In terms of impurity treatment, the directional high-pressure airflow generated by the blower is blown into the inner cavity of the outer shell through the air outlet hood. During the rotation of the scrap steel, the rust and slag on the surface fall off due to friction. The rust and slag and other light impurities such as plastics can be blown out from the slag discharge port by the directional high-pressure airflow, realizing the effective cleaning of impurities on the surface of the scrap steel.

[0031] The working principle of this utility model is as follows: First, the scrap steel sorting device is powered on, and the drive motor 206, vibrating motor 305, and fan 6 are turned on respectively. The output shaft of the drive motor 206 drives the gear 207 to rotate, the gear 207 drives the gear ring 204 to rotate, and the gear ring 204 drives the sorting drum 202 to rotate. The dust cover on the top of the feeding hopper 11 is opened, and the scrap steel is poured into the feeding hopper 11. The scrap steel slides down through the feeding hopper 11 into the sorting drum 202. The scrap steel is tumbled in the rotating sorting drum 202.

The scrap steel tumbles in the rotating sorting drum, and the rust on its surface is rubbed off. After falling from the sorting drum, the rust and light debris such as plastic are blown out from the slag discharge port 7 by the directional high-pressure airflow.
