Description

Technical Field

[0001] This utility model relates to the field of steel slag magnetic separation technology, specifically to a steel slag magnetic separation device for ash removal. Background Technology

[0002] In the steel production process, steel slag, as a type of smelting waste, is produced in huge quantities and has a complex composition, containing a large amount of iron and other metallic elements. Traditional steel slag treatment methods mainly rely on magnetic separation technology to recover and reuse the iron. However, during magnetic separation, dust and impurities in the steel slag are often separated along with the iron, which not only affects the purity of the iron but also generates a large amount of dust in subsequent processing, polluting the working environment and the ecological environment.

[0003] While existing steel slag magnetic separators on the market can effectively remove iron from steel slag, they still have shortcomings in ash removal. Many devices do not consider dust removal from the iron surface during the magnetic separation process, leading to the need for significant manpower and resources for dust removal in subsequent processing steps, increasing production costs and environmental pressure. Furthermore, some magnetic separators are structurally flawed, causing dust to easily accumulate inside the device, further exacerbating environmental pollution. Utility Model Content

[0004] The present invention aims to provide a steel slag magnetic separation device for ash removal, so as to solve the problem that existing steel slag magnetic separation devices generate a large amount of dust during the magnetic separation process, which affects the working environment and causes environmental pollution.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a magnetic separation device for removing ash from steel slag, comprising a magnetic separation component, a dust removal component, and a feeding cylinder. The magnetic separation component is used to select iron elements from the steel slag. The feeding cylinder is connected to the top of the magnetic separation cylinder. The dust removal component includes a dust removal box, a feeding channel, and a washing block. The top of the dust removal box extends through one side of the magnetic separation component. The feeding channel is inclined and has a trough at its top. The top of the feeding channel extends through the box and communicates with the inside of the magnetic separation cylinder. A scraper is connected to the top of the feeding channel and is connected to the top of the dust removal box. The bottom of the feeding channel extends through the bottom of the box. The washing block is connected to the top of the dust removal box and is located at the top of the feeding channel. The washing block is used to wash away dust from the surface of the iron elements. A water collection tank is provided at the bottom of the dust removal box.

[0006] The working principle of this utility model is as follows: Steel slag enters the magnetic separation component from the feed cylinder to begin magnetic separation. After magnetic separation, the iron elements fall through the scraper to the discharge channel and reach the dust collection box. The iron elements slide down the discharge channel, and the washing block starts spraying water. The water enters the discharge channel through the trough at the top of the discharge channel to wash the iron elements. The dust on the surface of the iron elements is washed away. The iron elements flow out of the discharge channel with the water and are filtered and collected. The water that does not enter the discharge channel is collected in the water cup collection tank.

[0007] The beneficial effects of this invention are as follows: 1. This device removes surface dust from the magnetically separated iron elements through a dust removal component, effectively avoiding a large amount of dust generated in subsequent iron element recycling processes, thereby significantly reducing pollution to the working environment and the ecological environment; 2. By removing dust from the surface of the iron elements simultaneously during the magnetic separation process, the purity of the magnetically separated iron elements is improved, making them more suitable for subsequent processing and utilization; 3. Traditional steel slag magnetic separation devices often require additional dust removal treatment after magnetic separation, which not only increases labor and material costs but also extends the processing cycle. The device of this invention, through its integrated design, completes the dust removal work during the magnetic separation process, thereby reducing production costs.

[0008] Furthermore, the magnetic separation assembly includes a magnetic separator drum and a magnetic separator ring. Fixed columns are located at both ends of the magnetic separator drum, with bearings connected to opposite sides of the fixed columns. A rotating column is connected between the bearings, passing through the central axis of the magnetic separator drum. The portion of the rotating column inside the magnetic separator drum is connected to the magnetic separator ring. A motor is connected to one of the fixed columns, and the motor's output shaft is connected to the rotating column. During operation, the motor is started, and the motor's output shaft drives the rotating column to rotate. The rotating column then drives the magnetic separator ring to rotate, continuously separating iron elements and transporting them to the discharge channel.

[0009] Furthermore, the rinsing block is connected to an external water tank, and the bottom of the rinsing block has multiple drain holes. The drain holes allow water to be sprayed evenly from the rinsing block.

[0010] Furthermore, a water pipe connects the water collection tank and the rinsing block, and a water pump is connected to the top of the water pipe. This water pipe arrangement allows water that does not enter the discharge channel to be recycled.

[0011] Furthermore, a stop block is connected to the top of the feeding channel, and the stop block is located at the bottom of the baffle. The stop block can limit the movement of the mixture inside the magnetic separator.

[0012] Furthermore, the feeding channel is bent, and the top and bottom feeding channels are not on a vertical plane. This design of the feeding channel ensures that the iron elements are thoroughly flushed out.

[0013] Furthermore, the bottom feeding channel is longer than the top feeding channel. This variation in the length of the feeding channels prevents iron elements at the outlet from being washed away, thus preventing splashing. Attached Figure Description

The top left side of the dust collection box passes through the magnetic separation cylinder and leaves a certain gap with the magnetic separation ring. The discharge channel is bent downwards, with the top and bottom discharge channels connected. Not on a vertical plane, the bottom feeding channel is longer than the top feeding channel. The top of each feeding channel is equipped with a trough. The top of the feeding channel passes through the box body and connects to the inside of the magnetic separator. A scraper is fixedly connected to the top of the feeding channel and is fixedly connected to the top of the dust collector.

[0020] The specific implementation process is as follows: Steel slag enters the magnetic separator from the feed cylinder.

The magnetic separator ring continuously magnetically separates and adsorbs iron elements. The iron elements after magnetic separation fall through the scraper into the discharge channel and reach the dust collection box. The iron elements slide down the discharge channel, and the drain hole of the washing block starts spraying water. The water enters the discharge channel through the trough at the top of the discharge channel to wash the iron elements. The dust on the surface of the iron elements is washed away. The iron elements flow out of the discharge channel with the water and are filtered and collected. The water cups that do not enter the discharge channel are collected in the water collection tank. The water pump draws the water in the water collection tank back into the washing block for washing.
