Description

Technical Field

[0001] This application relates to the technical field of iron powder production equipment, and in particular to a fine iron powder screening tank. Background Technology

[0002] Iron ore powder is a key raw material in metallurgy, machinery manufacturing, and chemical industries. Its purity and recovery rate directly affect the quality of downstream products and production efficiency. Screening is a crucial step in the iron ore powder processing flow, primarily used to separate impurities and particles of different sizes to obtain products that meet process requirements. The screening tank, as the core equipment in this process, plays a decisive role in screening efficiency and iron ore recovery rate due to its rational structural design.

[0003] Currently, the filters in existing screening tanks can only effectively intercept iron powder with larger particle sizes. Fine iron powder is usually mixed with fine dust particles. During the washing and dust removal process, some fine iron powder is discharged from the screening tank along with the washing water, resulting in serious waste of resources. Utility Model Content

[0004] In order to reduce the loss of fine iron powder during the dust removal process of refined iron powder, this application provides a refined iron powder screening tank.

[0005] The iron powder screening tank provided in this application adopts the following technical solution: A fine iron powder screening tank includes a holding hopper, a vibrating screen installed at the lower end of the holding hopper, a first collection box located below the vibrating screen, a spraying assembly for spraying water onto the upper end of the vibrating screen installed at the lower end of the holding hopper, a conveyor belt at the discharge end of the vibrating screen, and a plurality of magnetic rollers installed inside the first collection box, one end of each magnetic roller being placed outside the first collection box, and a cleaning ring being slidably connected to each magnetic roller.

[0006] By adopting the above technical solution, the iron powder after preliminary impurity removal is placed in a holding hopper, and then the iron powder falls onto a vibrating screen along the holding hopper. The vibrating screen is then started to screen the refined iron powder, separating the fine iron powder and discharging the water sprayed by the spraying component. The first collection box collects the finer refined iron powder after screening. At the same time, the spraying component sprays water onto the upper part of the vibrating screen to better screen the refined iron powder. Then, the larger iron powder is conveyed to the next station by a conveyor belt. Meanwhile, the fine ferromagnetic substances in the refined iron powder are adsorbed by the magnetic suction roller, thereby finely absorbing the iron powder. When a lot of iron powder is adsorbed on the magnetic suction roller, the adsorbed substances on the magnetic suction roller can be cleaned by sliding the cleaning ring and the iron powder can be collected in a concentrated manner.

[0007] Optionally, the spray assembly includes a spray pipe fixedly connected to the lower end of the container, a plurality of nozzles are installed on the spray pipe, a water supply pipe is connected to the spray pipe, and a pump body is installed on the water supply pipe.

[0008] By adopting the above technical solution, water can be supplied to the spray pipe through the water supply pipe by starting the pump body.

[0009] Optionally, the spray pipe is arranged around the discharge end of the container.

[0010] By adopting the above technical solution, water can be sprayed more comprehensively onto the refined iron powder on the vibrating screen, thereby improving the cleaning and screening effect.

[0011] Optionally, a discharge roller is fixedly connected to one end of the magnetic roller outside the first collection box. The discharge roller is coaxially arranged with the magnetic roller, and the discharge roller is made of a non-magnetic material.

[0012] By adopting the above technical solution, the unloading roller and the magnetic roller are coaxial and made of non-magnetic material, which enables the fine iron powder adsorbed on the magnetic roller to fall off when it reaches the position of the unloading roller due to the loss of magnetic attraction, thus facilitating unloading.

[0013] Optionally, the lower end of the unloading roller is provided with a guide plate, which is fixedly connected to the outer wall of the first collection box.

[0014] By adopting the above technical solution, the guide plate can guide the material unloaded by the unloading roller to a designated position.

[0015] Optionally, the discharge end of the guide plate is provided with a second collection box.

[0016] By adopting the above technical solution, the guide plate guides the material unloaded by the unloading roller to the second collection box, which facilitates the centralized collection of the unloaded ferromagnetic material.

[0017] Optionally, a rubber scraper is fixedly connected to the inner wall of the cleaning ring, the rubber scraper is coaxially arranged with the cleaning ring, and the inner wall of the rubber scraper abuts against the outer wall of the magnetic roller.

[0018] By adopting the above technical solution, the cleaning ring can clean the magnetic roller; the rubber scraper is fixed on the inner wall of the cleaning ring and is coaxial with the cleaning ring, and its inner wall is pressed against the outer wall of the magnetic roller, which can more effectively clean the ferromagnetic substances adsorbed on the magnetic roller.

[0019] Optionally, a clean water tank is provided on one side of the first collection box, and a connecting pipe is connected between the clean water tank and the first collection box, with a valve installed on the connecting pipe.

[0020] By adopting the above technical solution, the clean water in the clean water tank can be allowed to flow into the clean water tank for collection by opening the valve.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The combination of vibrating screen and spray assembly improves the screening efficiency of refined iron powder, meeting the needs of large-scale production; 2. The spraying assembly sprays water onto the upper part of the vibrating screen, ensuring the uniformity and stability of the water spray and improving the screening effect; 3. The magnetic roller inside the first collection box can effectively separate magnetic substances from refined iron powder, reducing subsequent processing steps, lowering production costs and time, and improving production efficiency.

A vibrating screen 2 is installed at the lower end of the holding hopper 1. The vibrating screen 2 is a mining vibrating screen 2 in the prior art. A conveyor belt 6 is provided at the discharge end of the vibrating screen 2. A first collection box 3 is provided below the vibrating screen 2. A spray assembly 5 for spraying water onto the upper part of the vibrating screen 2 is installed at the lower end of the holding hopper 1.

[0026] The spray assembly 5 includes a spray pipe 51 fixedly connected to the lower end of the holding hopper 1, and the spray pipe 51 is arranged around the discharge end of the holding hopper 1. Multiple nozzles 53 are installed on the spray pipe 51, and the nozzles 53 face the upper end face of the vibrating screen 2. The multiple nozzles 53 are equidistantly arranged along the length of the spray pipe 51. A water supply pipe 52 is connected to the spray pipe 51, and a pump body 54 is installed on the water supply pipe 52.

[0027] Then the pump body 54 is started, and water is supplied to the spray pipe 51 through the water supply pipe 52, and then sprayed onto the upper surface of the vibrating screen 2 through the nozzle 53.

[0028] Multiple magnetic rollers 12 are installed inside the first collection box 3, and the multiple magnetic rollers 12 are placed in the same plane. One end of the magnetic roller 12 is placed outside the first collection box 3, and a discharge roller 8 is fixedly connected to the other end of the magnetic roller 12 outside the first collection box 3. The discharge roller 8 is coaxially arranged with the magnetic roller 12 and is made of non-magnetic material, such as rubber or plastic. A guide plate 11 is provided at the lower end of the discharge roller 8, and the guide plate 11 is fixedly connected to the outer wall of the first collection box 3. A second collection box 4 is provided at the discharge end of the guide plate 11. The second box is set in a cuboid shape, and the guide plate is inclined downward near the second collection box 4.

[0029] A cleaning ring 7 is slidably connected to the magnetic roller 12, and the cleaning ring 7 corresponds one-to-one with the magnetic roller 12.

The rubber scraper 9 is coaxially arranged with the cleaning ring 7, and the inner wall of the rubber scraper 9 abuts against the outer wall of the magnetic roller 12.

[0030] Thus, the magnetic roller 12 can adsorb fine ferromagnetic substances in the refined iron powder, thereby finely absorbing the iron powder. When a large amount of iron powder is adsorbed on the magnetic roller 12, the cleaning ring 7 can be slid to move the iron filings to the unloading roller 8 via the rubber scraper 9. After losing magnetic adsorption, the iron filings fall onto the guide plate and slide into the second collection box 4 for collection.
