Description

Technical Field

[0001] This utility model relates to the field of iron oxide production and preparation technology, specifically a flushing iron oxide sieve device. Background Technology

[0002] In the existing technology, during the specific production process of iron oxide pigment, it is necessary to remove iron filings and impurities from the iron oxide pigment, which is the iron sieving process of iron oxide pigment. In the existing technology, components such as electromagnetic rods are directly set in the iron sieving box. The iron oxide pigment is poured into the iron sieving box, and the iron filings in the iron oxide pigment are attracted by the magnetic force of the electromagnetic rod, thereby effectively removing iron impurities from the iron oxide pigment.

[0003] For example, the technical solution disclosed in Publication No. CN220760015U, entitled "A Screening Device for Iron Oxide Pigment Production," includes a screening box body; a shaking groove is provided in the middle of the inner wall of the screening box body; a first support frame is provided in the middle of the shaking groove; the first support frame is slidably engaged with the shaking groove; a screening screen is provided in the middle of the first support frame; a first support seat is fixedly connected to the bottom of the first support frame; an electric push rod is fixedly connected to the inner wall of the screening box body; and a second support seat is fixedly connected to the side wall of the electric push rod. This step, by including the screening box body, shaking groove, first support frame, screening screen, first support seat, electric push rod, and second support seat, can screen iron oxide raw materials, thereby reducing the situation where iron oxide raw materials accumulate on the top of the screening screen and cause screen blockage, affecting the filtration efficiency of iron oxide raw materials, and improving the screening effect of iron oxide raw materials.

[0004] For example, the technical solution disclosed in Publication No. CN114029160A, entitled "A Screening Mechanism for Iron Oxide Production Slurry," includes a vertically placed screening box. A feed pipe is installed at the bottom of the screening box, and a discharge pipe is installed at the top. Several iron screening plates are installed inside the screening box from bottom to top. One of two adjacent screening plates is installed on the left side wall of the screening box, and an opening is left at the right end of the screening plate. In this invention, the screening plates inside the box are installed in a staggered manner from bottom to top. During the upward S-shaped flow of the slurry, iron filings inside the slurry are adsorbed onto the screening plates, and then the slurry is discharged from the discharge pipe above. On the one hand, the staggered screening plates effectively increase the adsorption area of ​​iron filings; on the other hand, the S-shaped flow path increases the flow time, both of which effectively improve the screening efficiency and screening quality of this invention.

[0005] However, in the above technical solutions, after the magnetic rod or magnetic plate attracts iron filings, the magnetic force of the magnetic rod or magnetic plate is lost by disconnecting the power. With this design, the attracted iron filings will fall off automatically. However, in actual operation, in many devices and equipment, after the magnetic rod attracts iron filings and the power is disconnected, some iron filings will still be attracted to the magnetic rod due to static electricity or adhesion. It is impossible to achieve the goal of the iron filings falling off naturally after the power is disconnected, which makes the subsequent recycling and removal of iron filings very inconvenient.

[0006] Therefore, in order to solve the above problems, it is necessary to develop a flushing iron oxide sieve device with a reasonable structure that can effectively remove adsorbed iron filings. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a flushing-type iron oxide sieve device; the technical solution is as follows:

These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0025] like Figure 2 As shown, a rinsing nozzle 6 is provided at the lower end face of the cover plate 2, and several evenly spaced rinsing nozzles 6 are provided around each rod part 32. The spray direction of the rinsing nozzles 6 is downward and aimed at the corresponding rod part 32. A rinsing channel 7 is also provided inside the cover plate 2. The rinsing channel 7 is connected to the rinsing nozzle 6. The rinsing channel 7 inside the cover plate 2 is also connected to a rinsing pipe 8. The rinsing pipe 8 is located outside the cover plate 2 and is connected to a water pump 9. The water pump 9 sends cleaning water into the rinsing channel 7 and sprays it out through the rinsing nozzle 6 to rinse the rod part 32.

[0026] A liquid inlet pipe 10 is provided on the upper left side of the iron sieve box 1, and a liquid outlet pipe 11 is provided on the lower right side of the iron sieve box 1; both the liquid inlet pipe 10 and the liquid outlet pipe 11 are equipped with solenoid valves; a discharge pipe 12 is provided at the lower end of the iron sieve box 1, and a corresponding solenoid valve is provided on the discharge pipe 12.

[0027] like Figure 4 As shown, the cover plate 2 has a total of twenty-five electromagnetic rod assemblies 3 arranged in an array of five rows and five columns.

[0028] Each rod portion 32 of the electromagnetic rod assembly 3 is provided with six evenly spaced flushing nozzles 6; the flushing nozzles 6 are obliquely arranged and are all aligned with the rod portion 32 of the electromagnetic rod assembly 3.

[0029] like Figure 3 As shown, a water collection cover 13 is also provided at the lower end face of the cover plate 2. A water collection cover 13 is provided at the position of the rod part 32 of each electromagnetic rod assembly 3. The water collection cover 13 covers the six flushing nozzles 6 corresponding to the rod part 32 inside, while the rod part 32 of the electromagnetic rod assembly 3 passes downward through the water collection cover 13. A water drop hole 14 is also provided on the water collection cover 13.

[0030] The specific working process of this device is as follows: The slurry of iron oxide pigment enters the iron screening box through the inlet pipe. Then, the electromagnetic rod assembly is energized by the electromagnetic controller, and the rod body generates a corresponding magnetic force. The iron filings in the slurry are attracted and fixed to the rod body, completing the iron screening process. After screening, the remaining slurry is discharged from the outlet pipe. At this time, there are many iron filings adsorbed on the rod body. Then, the electromagnetic rod assembly is de-energized by the electromagnetic controller, and the rod body of the electromagnetic rod assembly is de-energized. The magnetic force disappears. Under normal circumstances, the iron filings adsorbed on the rod body will fall off due to natural gravity. However, they may still be adsorbed on the rod body due to static electricity or other adhesion. At this time, the iron filings adsorbed on the rod body can be washed off by rinsing.

[0031] Turn on the water pump to transport water into the rinsing channel, and then spray it out from the rinsing nozzle. The rinsing nozzle is aimed downward at the rod body to wash off the iron filings and other residues on the rod body, thus achieving the washing of iron filings.

[0032] Furthermore, to conserve water resources and enable more precise rinsing of the rod body, this device is equipped with a water collection hood. The water collection hood is located at the upper end of each rod body, and the position of the rinsing nozzle corresponds to the position of the water collection hood. After the water is sprayed downward from the rinsing nozzle, it is collected by the water collection hood. The lower end of the water collection hood is also equipped with a drain hole, the position of which also corresponds to the position of the rod body. Therefore, after the water falls from the drain hole of the water collection hood, it can also rinse the rod body. The structure is more reasonable, and it can save water resources and accurately rinse the rod body.

All equivalent changes and modifications made in accordance with the scope of protection of this utility model patent application should be included within the scope of this utility model patent application.
