Description

Technical Field

[0001] This invention relates to the field of zirconia screening equipment, and more particularly to an intelligent zirconia magnetic separation screening device. Background Technology

[0002] Magnetic separation screening technology for zirconia is a separation method that uses magnetic force for screening. It separates iron slag from zirconia through the magnetic force generated by an electromagnet, improving the purity of zirconia and the quality of processed zirconia products. Although magnetic separation screening technology has many advantages, it also has several drawbacks in practical applications. For example, iron slag and zirconia are prone to electrostatic agglomeration during magnetic separation screening, resulting in poor screening efficiency. Furthermore, when screening small batches of iron slag and zirconia, a large amount of dust and debris is easily generated, leading to material waste and environmental pollution that can harm workers' health. Additionally, the electromagnet generates a large amount of heat when applying magnetic force for extended periods, which can interfere with the applied magnetic force and affect the screening efficiency of iron slag and zirconia. Summary of the Invention

This improves the magnetic separation and screening effect of iron slag and zirconia while reducing the power cost of the electromagnet. It overcomes the shortcomings of traditional magnetic separation and screening methods, which have poor screening effects on agglomerated iron slag and zirconia and generate a large amount of dust.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0018] Example 1: An intelligent zirconia magnetic separation and screening device of the present invention, such as... Figures 1-6As shown, it includes a mounting frame 1, a screening chamber 2, a discharge pipe 3, a central rotating drum 4, a drive motor 5, a spiral push rod 6, an arc-shaped magnetic guide plate 7, an arc-shaped insulating plate 8, and an electromagnet 9; the mounting frame 1 is fixedly connected to the screening chamber 2, which is inclined downwards to the right; the screening chamber 2 is provided with a feed inlet 201 structure; the screening chamber 2 is provided with a slag outlet 202 structure, and the slag outlet 202 is located to the left of the feed inlet 201; the feed inlet 201 of the screening chamber 2 is equipped with a concentration detector, and the concentration... The concentration detector can intelligently monitor the concentration of the mixed slurry entering the feed inlet 201; a discharge pipe 3 is fixedly connected to the right side of the mounting frame 1; the discharge pipe 3 is connected to the right outlet end of the screening chamber 2; a central rotating drum 4 is rotatably connected inside the screening chamber 2; a drive motor 5 is mounted on the mounting frame 1; the output shaft of the drive motor 5 is fixedly connected to the central rotating drum 4; a spiral push rod 6 is fixedly connected to the central rotating drum 4, and the spiral push rod 6 is in close contact with the inner wall of the screening chamber 2; an arc-shaped magnetic conductor is fixedly connected to the lower part of the screening chamber 2. Plate 7; An arc-shaped insulating plate 8 is fixedly connected to the lower part of the screening chamber 2, and the arc-shaped insulating plate 8 is located to the left of the arc-shaped magnetic plate 7; the arc-shaped insulating plate 8 has a hollow groove 801 structure, and the hollow groove 801 is connected to the feed inlet 201 of the screening chamber 2; an electromagnet 9 is installed on the screening chamber 2 to apply magnetic force to the arc-shaped magnetic plate 7. The electromagnet 9 can intelligently change the magnetic force according to the concentration of the mixed slurry. The higher the concentration of the mixed slurry, the stronger the magnetic force applied by the electromagnet 9 to the arc-shaped magnetic plate 7. The smaller the applied magnetic force, the more the electromagnet 9 is located on the side of the arc-shaped magnetic plate 7 away from the arc-shaped insulating plate 8. Since the area of ​​the arc-shaped magnetic plate 7 further away from the electromagnet 9 is, the smaller the magnetic force applied by the electromagnet 9 to that area of ​​the arc-shaped magnetic plate 7, the magnetic force at the left end of the arc-shaped magnetic plate 7 is less than that in the middle area. Furthermore, the further away the iron filings that move onto the arc-shaped insulating plate 8 are from the arc-shaped magnetic plate 7 and the electromagnet 9, the closer the magnetic force from the left end of the arc-shaped magnetic plate 7 on the iron filings is to zero.

[0019] like Figure 5 As shown, the central rotating drum 4 has a smooth, splitting hemispherical head 401 structure in the area aligned with the feed inlet 201; the central rotating drum 4 has a splash guard 402 structure, and the splash guard 402 is located to the left of the splitting hemispherical head 401; as the mixed slurry flowing out of the feed inlet 201 contacts and flows downward through the splitting hemispherical head 401 of the central rotating drum 4, the smooth splitting hemispherical head 401 can reduce the splashing liquid generated by the collision with the mixed slurry, and the mixed slurry, when in contact with the smooth splitting hemispherical head 401, can reduce the splashing liquid generated by the collision with the mixed slurry. A small amount of splashed liquid generated during the collision of the head 401 will be intercepted by the splash guard 402, preventing the mixed slurry flowing out of the feed inlet 201 from generating a large amount of splashed liquid during the downward collision of the central rotating cylinder 4 and falling directly into the hollow groove 801; the central rotating cylinder 4 is provided with several annular grooves 403; several dispersing rods 41 are fixedly connected in each annular groove 403 of the central rotating cylinder 4; the spiral push rod 6 is provided with several drainage grooves 601 on one side of the inner wall of the screening chamber 2.

[0020] The steps for using the intelligent zirconia magnetic separation and screening equipment of the present invention are as follows.

[0021] First, the staff connects the discharge pipe 3 to an external filtration device and the slag outlet 202 of the screening chamber 2 to an external collection container. Then, the staff mixes zirconium oxide and iron slag in pure water to form a mixed slurry. Using an external conveying device, the mixed slurry is sequentially fed into the screening chamber 2 through the inlet 201. The mixed slurry flows slightly upwards along the lower side of the inclined screening chamber 2 towards the discharge pipe 3. Simultaneously, the drive motor 5 drives the central rotating drum 4 and the spiral push rod 6 to rotate. The spiral push rod 6 continuously stirs the mixed slurry in the screening chamber 2. When the stirred mixed slurry flows through the annular groove 403 of the central rotating drum 4, the dispersing rod 41 in the annular groove 403 continuously disperses the zirconium oxide and iron slag in the mixed slurry. Furthermore, when the mixed slurry flows out of the annular groove 403, some of the zirconium oxide and iron slag in the mixed slurry are guided by the annular groove 403. Under the action of the magnetic force, the slurry flows towards the arc-shaped magnetic plate 7, so that the zirconium oxide and iron slag in the mixed slurry are continuously pushed towards the arc-shaped magnetic plate 7. At the same time, the electromagnet 9 applies magnetic force to the arc-shaped magnetic plate 7. The arc-shaped magnetic plate 7 magnetically captures the iron slag in the mixed slurry through the magnetic force. The rotating spiral push rod 6 continuously pushes the iron slag captured on the arc-shaped magnetic plate 7 to the arc-shaped insulating plate 8. Then, the rotating spiral push rod 6 continuously pushes the iron slag on the arc-shaped insulating plate 8 into the hollow groove 801. Finally, the iron slag passes through the hollow groove 801 and the slag outlet 202 of the screening chamber 2 and is recovered into the external collection container. The remaining zirconium oxide in the mixed slurry flows out through the discharge pipe 3 to the external filtration equipment, where the zirconium oxide in the mixed slurry is filtered out, thus achieving efficient magnetic separation and screening of iron slag and zirconium oxide.

[0022] During the flow of some zirconium oxide in the mixed slurry towards the arc-shaped magnetic plate 7, there is a phenomenon where zirconium oxide is intercepted between the spiral push rod 6 and the arc-shaped magnetic plate 7. When the drain groove 601 in the spiral push rod 6 rotates past the intercepted zirconium oxide, the zirconium oxide can smoothly pass through the drain groove 601 and leave the spiral push rod 6 under the push of the flowing mixed slurry. When the rotating spiral push rod 6 continuously pushes the iron slag along the arc-shaped insulating plate 8, when the drain groove 601 in the spiral push rod 6 rotates past the iron slag, due to the large amount of moisture on the surface of the iron slag, the iron slag will remain on the surface of the arc-shaped insulating plate 8 under the adhesion of the moisture and will not pass through the drain groove 601 along the inclined arc-shaped insulating plate 8, allowing the iron slag to be smoothly pushed into the hollow groove 801 by the spiral push rod 6.

[0023] The pure water in the mixed slurry can not only reduce the agglomeration of zirconium oxide and iron slag and inhibit the generation of slag dust, but also act as cooling water to remove the heat generated by the electromagnet 9 in time, reducing the interference caused by the magnetic force applied by the heat to the electromagnet 9. While improving the magnetic separation and screening effect of iron slag and zirconium oxide, it also reduces the power cost of the electromagnet 9.

[0024] Example 2, based on Example 1 above, as follows: Figures 1-6 As shown, in this embodiment, the spiral pusher 6 is equipped with several permanent magnet strips 61 inside the area above the arc-shaped magnetic guide plate 7. The spiral pusher 6 is made of a non-magnetic material. Therefore, the magnetic force exerted by the permanent magnet strips 61 through the spiral pusher 6 is less than the magnetic force exerted by the electromagnet 9 on the arc-shaped magnetic guide plate 7. When the mixed slurry flows through the screening chamber 2, if some iron slag does not come into contact with the arc-shaped magnetic guide plate 7 and cannot be successfully magnetically captured, this part of the iron slag will be magnetically captured by the permanent magnet strips 61 through the magnetic force exerted by the spiral pusher 6 when it comes into contact with the surface of the spiral pusher 6. Then, when the spiral pusher 6 drives the magnetically captured iron slag through the arc-shaped magnetic guide plate 7, since the magnetic force on the arc-shaped magnetic guide plate 7 is greater than the magnetic force exerted by the permanent magnet strips 61 through the spiral pusher 6, the iron slag magnetically captured on the spiral pusher 6 will be magnetically transferred to the arc-shaped magnetic guide plate 7, which improves the capture success rate of iron slag in the mixed slurry and further improves the magnetic separation and screening effect of iron slag and zirconium oxide.

[0025] Example 3, based on Example 1 above, as follows: Figures 1-6As shown, in this embodiment, a cleaning brush 81 is provided on the hollow groove 801 of the arc-shaped insulating plate 8; an electric blower 10 is installed on the front and rear sides of the screening chamber 2, and the air outlet structure of the electric blower 10 is facing the hollow groove 801 of the arc-shaped insulating plate 8; each of the two electric blowers 10 has a built-in electric heater; a baffle 203 structure is provided on the left end of the screening chamber 2; during the continuous pushing of the rotating spiral pusher 6 towards the hollow groove 801, some of the iron slag on the arc-shaped insulating plate 8 is adhered to the surface of the spiral pusher 6 and the inner wall of the arc-shaped insulating plate 8 due to its high moisture content and cannot fall into the hollow groove 801. When the spiral pusher 6 drives the adhered iron slag to rotate and pass through the cleaning brush 81, the cleaning brush 81 can brush off some of the iron slag adhering to the surface of the spiral pusher 6, allowing the iron slag to fall smoothly into the hollow groove 801. At the same time, the two electric blowers 10 blow airflow towards the hollow groove 801, and the electric heaters built into the electric blowers 10 also blow airflow. The blowing airflow is heated, allowing the hot airflow to continuously flow through the inner wall of the arc-shaped insulating plate 8 and into the hollow groove 801. The hot airflow dries the moisture on the surface of the slag, allowing the slag to fall smoothly from the surface of the spiral pusher 6 and the inner wall of the arc-shaped insulating plate 8 into the hollow groove 801 after the moisture is dried. In addition, some small-volume slag, after being dried, is blown upward by the hot airflow. The small-volume slag blown upward to the left and upward... The slag will be blocked by the baffle 203 at the left end of the screening chamber 2 and fall back into the hollow groove 801. The small volume of iron slag blown to the upper right will fall into the mixed slurry in the screening chamber 2, allowing the small volume of iron slag to adhere to water again and be pushed onto the arc-shaped insulating plate 8 by the spiral pusher 6. At this time, the small volume of iron slag adheres to the arc-shaped insulating plate 8 due to the influence of water, so it cannot be blown up by the hot airflow again. Finally, the small volume of iron slag is pushed into the hollow groove 801 by the spiral pusher 6.
