Description

Technical Field

[0001] This utility model relates to the field of alkaline solution purification technology, and in particular to a magnetic filtration and separation device. Background Technology

[0002] In the alkaline solution purification process, some alkaline solutions contain a large amount of iron powder. To avoid waste, it is necessary to collect the iron powder. Therefore, a magnetic filtration and separation device is required. During use, the device can adsorb the iron powder from the water onto the surface of the magnetic drum. Then, the water in the iron powder is squeezed out by the squeezing roller, and the iron powder adsorbed on the surface of the magnetic drum is scraped off and collected by the scraper, which facilitates subsequent transportation and processing.

[0003] In existing technologies, the extrusion roller is typically powered by friction between itself and a magnetic drum. However, when processing alkaline solutions, the cleaning fluid inside reduces friction and decreases the extrusion effect. Furthermore, in most magnetic drums, the magnets are fixed in position, making it inconvenient for users to adjust the magnitude and direction of the magnetic force, which hinders practicality. Therefore, those skilled in the art have provided magnetic filtration and separation devices to address the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a magnetic filtration and separation device. During use, the device uses a first gear, a second gear, and a synchronous belt to prevent the extrusion roller from slipping during movement, thereby reducing the extrusion effect. In addition, the user can freely select the number of magnetic strips inside the magnetic drum to adjust the magnetic force of the drum, thus improving its practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic filtration and separation device, comprising a squeezing roller, a first outer shell, a conveying port, a scraper, a magnetic drum, a motor, a first support, and a synchronous belt. The magnetic drum comprises a chute, two second supports, a rotating shaft, two third supports, a magnetic strip, a bolt, two fixing rings, a second outer shell, and a protruding strip.

[0006] The extrusion roller includes a main body, which is rotatably mounted on the upper front end of the first outer shell. A first gear is fixedly mounted at both ends of the main body. The rotating shaft is rotatably mounted inside the first outer shell. A second gear is fixedly mounted at both ends of the rotating shaft. A synchronous belt connects each pair of the two first gears and the two second gears.

[0007] Furthermore, the conveying port is opened through the upper front end of the first housing, the scraper is fixedly installed at the rear end of the first housing, and one end of the scraper is attached to the surface of the magnetic drum.

[0008] Furthermore, the slide groove is fixedly disposed around the rotating shaft, and the two second brackets are fixedly disposed at both ends of the slide groove.

[0009] Furthermore, each of the two second brackets and the slide grooves is provided with four sets, and the two fixing rings are fixedly arranged around the two ends of the four slide grooves.

[0010] Furthermore, the two No. 3 brackets are fixedly installed between the two fixed rings, and the opposite sides of the two No. 3 brackets each have a certain slope.

[0011] Furthermore, the magnetic strip is fixed inside the two No. 3 brackets by two bolts, and multiple No. 3 brackets, two bolts, and magnetic strips are provided.

[0012] Furthermore, the four protruding strips are fixedly installed inside the second outer shell, and the sliding groove, the two second brackets, the rotating shaft, the two third brackets, the magnetic strip, the bolt, and the two fixing rings are all slidably installed inside the second outer shell.

[0013] This utility model has the following beneficial effects:

[0014] 1. The magnetic filtration and separation device proposed in this utility model has the following characteristics: when the magnetic drum rotates, it drives the second gear to rotate, which in turn drives the first gear to rotate via a synchronous belt. The first gear drives the main body to rotate, which helps to prevent the extrusion roller from slipping when it is driven to rotate by the magnetic drum, thereby reducing the extrusion effect. In addition, the two ends of the rotating shaft are connected, which makes it convenient to install a transmission shaft to drive the magnetic drum to rotate.

[0015] 2. The magnetic filtration and separation device proposed in this utility model allows the user to pull out the rotating shaft and adjust the number of magnetic strips during use. When installing the magnetic strips, simply place them between two No. 3 brackets. Since both the No. 3 brackets and the magnetic strips have a certain slope, the magnetic strips will not fall off after being placed between the two No. 3 brackets, making it convenient for the user to fix them with bolts. The user can adjust the magnitude and direction of the magnetic force by installing different numbers of magnetic strips, improving practicality and making replacement very convenient.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a magnetic filtration and separation device, including a squeezing roller 1, a first outer shell 2, a conveying port 3, a scraper 4, a magnetic drum 5, a motor 6, and a first support 7. The magnetic drum 5 includes a sliding groove 502, two second supports 501, a rotating shaft 504, two third supports 505, a magnetic strip 506, a bolt 507, two fixing rings 508, a second outer shell 509, and a protrusion 510. The conveying port 3 is opened through the upper front end of the first outer shell 2. The scraper 4 is fixedly set at the rear end of the first outer shell 2. One end of the scraper 4 is attached to the surface of the magnetic drum 5. The two first gears 102 and the two second gears 503 are connected by synchronous belts 8 in pairs.

[0025] Specifically, the conveyor 3 facilitates the delivery of cleaning fluid into the first outer casing 2; the scraper 4 facilitates the removal of iron powder adsorbed around the magnetic drum 5; and the timing belt 8 facilitates the connection between the first gear 102 and the second gear 503, so that when the magnetic drum 5 drives the extrusion roller 1 to rotate, the extrusion roller 1 is less likely to slip, thus avoiding a reduction in the extrusion effect.

[0026] Reference Figure 3 , Figure 4 and Figure 5The extrusion roller 1 includes a main body 101, which is rotatably mounted on the upper front end of the first outer shell 2. A first gear 102 is fixedly mounted at both ends of the main body 101. A rotating shaft 504 is rotatably mounted inside the first outer shell 2. A second gear 503 is fixedly mounted at both ends of the rotating shaft 504. A slide groove 502 is fixedly mounted around the rotating shaft 504. Two second supports 501 are fixedly mounted at both ends of the slide groove 502. There are four sets of two second supports 501 and four sets of slide grooves 502. Two fixing rings 508 are fixedly mounted around both ends of the four slide grooves 502.

[0027] Specifically, the main body 101 helps to squeeze the surface of the magnetic drum 5, causing the cleaning liquid inside the iron powder to be squeezed out; the groove 502 and the protrusion 510 help to keep the inside and outside of the magnetic drum 5 consistent when rotating, avoiding asynchronous rotation of the inside and outside, which would reduce the adsorption effect; the second bracket 501 helps to install the fixing ring 508.

[0028] Two No. 3 brackets 505 are fixedly installed between two fixed rings 508. The opposite sides of the two No. 3 brackets 505 have a certain slope. The magnetic strip 506 is fixedly installed inside the two No. 3 brackets 505 by two bolts 507. There are multiple No. 3 brackets 505, two bolts 507 and magnetic strips 506. Four protrusions 510 are fixedly installed inside the No. 2 outer shell 509. The slide groove 502, the two No. 2 brackets 501, the rotating shaft 504, the two No. 3 brackets 505, the magnetic strip 506, the bolts 507 and the two fixed rings 508 are all slidably installed inside the No. 2 outer shell 509.

[0029] Specifically, the No. 3 bracket 505 facilitates the installation of the magnetic strip 506. Multiple No. 3 brackets 505 allow users to adjust the magnitude and direction of the magnetic force by installing different numbers of magnetic strips 506. A certain slope is provided on the opposite side of every two No. 3 brackets 505 to prevent the magnetic strip 506 from falling when placed between them, and it is easy to secure it with bolts 507. The No. 2 outer shell 509 and the protrusion 510 of the magnetic drum 5 are connected to other parts by a sliding snap-fit ​​connection, making it easy for users to replace the magnetic strip 506.

[0030] Working principle: When in use, the cleaning fluid is pumped into the guide groove at the lower end of the outer shell by a delivery pump and flows around the magnetic drum 5. Under the magnetic field of the magnetic drum 5, the iron powder is attracted to the surface of the magnetic drum 5. A sludge squeezing roller 1 is provided on the upper side of the magnetic drum 5. The iron powder attracted to the surface of the magnetic drum 5 inevitably carries some cleaning fluid. As the magnetic drum 5 rotates, the iron powder is squeezed by the sludge squeezing roller 1, and the cleaning fluid is squeezed out and flows back to the first outer shell 2 to ensure the dryness of the extracted iron powder for easy processing and transportation. On the other side of the drum is a scraper 4. The iron powder attracted by the magnetic drum 5 and squeezed dry by the squeezing roller 1 is scraped off the magnetic drum 5 by the scraper 4 when the magnetic drum 5 rotates to this point and falls to the ground.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
