Description

Technical Field

[0001] This application relates to iron powder recovery equipment, and more particularly to an iron ore beneficiation wastewater recovery device. Background Technology

[0002] As a crucial raw material in powder metallurgy, iron powder plays a vital role in cast iron ingot manufacturing and equipment manufacturing. When the purity of raw iron powder cannot meet production requirements, the industry commonly employs iron beneficiation processes for purification. This process mainly includes ball milling and multiple magnetic separation steps. During ball milling and magnetic separation, a certain amount of circulating water is added for auxiliary treatment to ensure smooth process operation. After the magnetic separation process, vacuum filters are typically used to dehydrate the iron powder to accelerate drying.

[0003] In conventional operation, when a vacuum filter is running, the negative pressure principle forces wastewater through the filter cloth and into the wastewater settling tank via the equipment's outlet pipe. Iron powder is trapped by the filter cloth, thus achieving dewatering. However, in actual operation, some fine iron powder particles cannot be completely intercepted by the filter cloth. These fine particles pass through the filter cloth along with the wastewater and enter the wastewater settling tank via the outlet pipe. Ultimately, this lost iron powder settles in the tank. Due to the lack of efficient recovery methods, it is difficult to reuse, resulting in a waste of iron powder resources, increased production costs and resource consumption for the enterprise, and reduced overall production efficiency. Utility Model Content

[0004] In order to recover residual iron powder from wastewater, this application provides an iron ore beneficiation wastewater recovery device.

[0005] The iron ore beneficiation wastewater recovery device provided in this application adopts the following technical solution:

[0006] An iron ore beneficiation wastewater recovery device includes a tank body with an inlet pipe connected to the tank body and connected to the outlet of a filter. A drain pipe is also connected to the tank body. Multiple iron powder adsorption columns for adsorbing iron powder are fixedly connected inside the tank body. The iron powder adsorption columns are arranged along the height of the tank body. An iron powder scraping ring is slidably connected to each iron powder adsorption column. A drive assembly is installed on the tank body to move the iron powder scraping ring up and down along the iron powder adsorption columns. A collection chamber is installed and connected to the lower end of the tank body. A discharge pipe is fixedly connected and connected to the lower end of the collection chamber. A control valve is installed on the discharge pipe. The collection chamber is positioned directly below the iron powder adsorption columns.

[0007] By adopting the above technical solution, the wastewater discharged from the filter can enter the tank and be adsorbed by multiple iron powder adsorption columns inside the tank, so that the iron powder adheres to the iron powder adsorption columns. Then, after the wastewater has completely passed through the tank, the drive component can be controlled to drive the iron powder scraping ring to descend, so that the iron powder adsorbed on the iron powder adsorption columns falls into the collection chamber along the iron powder adsorption columns, thereby collecting the iron powder in a concentrated manner. Then, by opening the discharge pipe, the iron powder and part of the wastewater accumulated in the collection chamber are discharged from the collection chamber together, thereby quickly recovering the iron powder.

[0008] Optionally, the iron powder adsorption column includes a magnetic part and a non-magnetic part, wherein the non-magnetic part is located on the side of the iron powder adsorption column near the collection chamber.

[0009] By adopting the above technical solution, when the iron powder moves to the non-magnetic part of the iron powder adsorption column, the iron powder and the automatic iron powder adsorption column are separated, which facilitates the centralized collection of iron powder.

[0010] Optionally, an annular scraper is fixedly connected to the iron powder scraping ring, and the annular scraper is arranged along the end face of the iron powder scraping ring.

[0011] By adopting the above technical solution, iron powder on the iron powder adsorption column can be scraped off by an annular scraper, which facilitates the collection of iron powder.

[0012] Optionally, the drive assembly includes a crossbar, and a connecting rod is fixedly connected between the crossbar and each of the iron powder scraping rings. The tank body is provided with a drive component for driving the crossbar to rise or fall.

[0013] By adopting the above technical solution, the driving component can be controlled to move the iron powder scraping ring up and down via the crossbar and connecting rod.

[0014] Optionally, the driving component is configured as a driving cylinder, which is fixedly connected to the upper end of the tank body, and the telescopic end of the driving cylinder passes through the tank body and is fixedly connected to the crossbar.

[0015] By adopting the above technical solution, the extension and retraction of the drive cylinder can be controlled, thereby causing the drive cylinder to move the crossbar.

[0016] Optionally, the upper part of the collection chamber is rotatably connected to two sealing plates, and an elastic rod for maintaining the sealing plate's sealing of the collection chamber is fixedly connected between the sealing plate and the inner wall of the collection chamber.

[0017] By adopting the above technical solution, the inside of the collection chamber can be blocked by the sealing plate, reducing the occurrence of some large-diameter impurities settling in the collection chamber and thus affecting the collection effect of the collection chamber.

[0018] Optionally, two abutment rods are fixedly connected to the lower end face of the iron powder scraping ring. The abutment rods are used to abut against the sealing plate, and the ends of the two abutment rods away from the iron powder scraping ring extend away from each other.

[0019] By adopting the above technical solution, when the iron powder scraping ring descends to a certain height, it can be abutted against the sealing plate by the abutting rod, thereby allowing the sealing plate to open in advance so that the iron powder can enter the collection chamber.

[0020] Optionally, the elastic rod is made of rubber.

[0021] By adopting the above technical solution, the elastic rod made of rubber has good bending effect and strong corrosion resistance.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The drive component causes the iron powder scraping ring to descend, causing the iron powder adsorbed on the iron powder adsorption column to fall into the collection chamber along the iron powder adsorption column, thereby collecting the iron powder in a concentrated manner. Then, by opening the discharge pipe, the iron powder and some of the wastewater accumulated in the collection chamber are discharged from the collection chamber together, thereby quickly recovering the iron powder.

[0024] 2. The extension and retraction can be controlled by the drive cylinder, which in turn moves the crossbar.

[0025] 3. When the iron powder moves to the non-magnetic part of the iron powder adsorption column, the iron powder is automatically removed from the adsorption column, which facilitates the centralized collection of the iron powder. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0031] An embodiment of this application is: an iron ore beneficiation wastewater recovery device, referring to... Figure 1 It includes a tank 1, which is cylindrical in shape. A water inlet pipe 2 is connected to the tank 1 and is connected to the water outlet of the filter. The filter is not shown in the figure.

[0032] Reference Figure 1 and Figure 2 The lower part of the tank body 1 is connected to a drain pipe 3. Multiple iron powder adsorption columns 4 for adsorbing iron powder are fixedly connected inside the tank body 1. The iron powder adsorption columns 4 are set along the height of the tank body 1 and multiple iron powder adsorption columns 4 are set along the diameter direction of the end face of the tank body 1.

[0033] Therefore, the wastewater discharged from the filter can enter the tank 1, and the iron powder is adsorbed by multiple iron powder adsorption columns 4 in the tank 1, so that the iron powder is attached to the multiple iron powder adsorption columns 4.

[0034] An iron powder scraping ring 5 is slidably connected to the iron powder adsorption column 4. An annular scraper 8 for cleaning the iron powder adhering to the iron powder adsorption column 4 is fixedly connected to the iron powder scraping ring 5. The annular scraper 8 is arranged along the end face of the iron powder scraping ring 5. A drive assembly 6 is installed on the tank body 1 to drive the iron powder scraping ring 5 to move up and down along the iron powder adsorption column 4.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The drive assembly 6 includes a crossbar 61, with a connecting rod fixedly connected to each iron powder scraping ring 5. The tank body 1 is equipped with a drive component 62 for raising or lowering the crossbar 61. The drive component 62 is a drive cylinder, fixedly connected to the upper end of the tank body 1. The telescopic end of the drive cylinder passes through the tank body 1 and is fixedly connected to the crossbar 61. By controlling the telescopic movement of the drive cylinder, the crossbar 61 can be moved, causing the iron powder scraping rings 5 ​​to scrape the iron powder from the iron powder adsorption column 4.

[0036] Meanwhile, to facilitate the detachment of iron powder from the iron powder adsorption column 4, the iron powder adsorption column 4 includes a magnetic part 41 and a non-magnetic part 42, with the non-magnetic part 42 located on the side of the iron powder adsorption column 4 closest to the collection chamber 7. When the iron powder moves to the non-magnetic part 42 of the iron powder adsorption column 4, the iron powder can automatically detach from the iron powder adsorption column 4.

[0037] A collection chamber 7 is installed and connected to the lower end of the tank body 1. A discharge pipe 71 is fixedly connected and connected to the lower end of the collection chamber 7. A control valve 72 is installed on the discharge pipe 71. The collection chamber 7 is located directly below the iron powder adsorption column 4. Two sealing plates 9 are rotatably connected to the upper part of the collection chamber 7. The two sealing plates 9 are at the same height. An elastic rod 91 is fixedly connected between the sealing plates 9 and the inner wall of the collection chamber 7 to maintain the sealing of the collection chamber 7 by the sealing plates 9. The elastic rod 91 is made of rubber. Two abutment rods 10 are fixedly connected to the lower end face of the iron powder scraping ring 5. The abutment rods 10 are used to abut against the sealing plates 9. The ends of the two abutment rods 10 away from the iron powder scraping ring 5 extend away from each other.

[0038] When the iron powder scraping ring 5 descends to a certain height, it can be abutted against the sealing plate 9 by the abutting rod 10, thereby causing the sealing plate 9 to open in advance so that the iron powder can enter the collection chamber 7.

[0039] The iron powder adsorbed on the iron powder adsorption column 4 falls into the collection chamber 7 along the iron powder adsorption column 4, thereby collecting the iron powder in a concentrated manner. Then, by opening the discharge pipe 71, the iron powder and some of the wastewater accumulated in the collection chamber 7 are discharged together from the collection chamber 7, thereby quickly recovering the iron powder.
