Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0038] In this application, the term "comprising", "including" or any other variant thereof is intended to cover a non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "including a..." does not exclude the presence of additional identical elements in the process, method, article or device including the element.
[0039] An embodiment of the present invention provides an iron remover. Refer to Figures 1 to 4 , Figure 1 which is a structural schematic diagram of the iron remover. The iron remover includes: a first telescopic mechanism 1, a connecting plate 2, a connecting pipe 3, and a plurality of sub-iron removers 4;
[0040] The sub-iron remover 4 includes a cylinder body 41, a top cover 42, a dirt scraping device 43, a plurality of first magnetic bars 44, and a plurality of second magnetic bars 45;
[0041] The cylinder body 41 is provided with a first filtering channel 413 and a second filtering channel 414. The lower end of the cylinder body 41 is provided with a liquid inlet 411 communicating with the first filtering channel 413 and a liquid outlet 412 communicating with the second filtering channel 414. The upper end of the first filtering channel 413 is communicated with the upper end of the second filtering channel 414. The liquid outlet 412 is communicated with the liquid inlet 411 of another sub-iron remover 4 through the connecting pipe 3;
[0042] The top cover 42 is detachably and sealingly connected to the top of the cylinder body 41. The first magnetic bar 44 is arranged in the first filtering channel 413, and the second magnetic bar 45 is arranged in the second filtering channel 414. The upper ends of the first magnetic bar 44 and the second magnetic bar 45 are connected to the top cover 42. Among them, the first magnetic bar 44 is used to adsorb magnetic substances in the first filtering channel 413, and the second magnetic bar 45 is used to adsorb magnetic substances in the second filtering channel 414;
[0043] The dirt scraping device 43 is arranged on the top cover 42 and is used to scrape off the magnetic substances adsorbed by the first magnetic bar 44 and the second magnetic bar 45;
[0044] The extending end of the first telescopic mechanism 1 is adjacent to the top cover 42 of multiple sub-iron removers 4 through the connecting plate 2. The first telescopic mechanism 1 is used to drive the top covers 42 of multiple sub-iron removers 4 to synchronously lift and lower in the vertical direction, so as to drive the first magnetic bar 44 and the second magnetic bar 45 to lift and lower in the vertical direction.
[0045] It should be noted that the liquid to be filtered flows into the first filtering channel 413 through the liquid inlet 411. The liquid passes through the first magnetic bar 44 inserted into the first filtering channel 413. The magnetic force generated by the first magnetic bar 44 adsorbs the magnetic substances in the liquid, performs primary iron removal on the liquid, and gradually flows into the second filtering channel 414. The second magnetic bar 45 inserted into the second filtering channel 414 then performs secondary iron removal on the magnetic substances in the liquid through the generated magnetic force, further reducing the magnetic substances in the liquid. The filtered liquid then enters the next sub-iron remover 4 through the connecting pipe 3 for two times of iron removal, further reducing the content of magnetic substances in the liquid.
[0046] It is worth noting that when those skilled in the art set the number of sub-iron removers 4, they can choose according to requirements.
[0047] It also needs to be explained that since the top cover 42 is detachably and sealingly connected to the top of the cylinder body 41, after the extending end of the first telescopic mechanism 1 is connected to the top covers 42 of multiple sub-iron removers 4 through the connecting plate 2, the first telescopic mechanism 1 can drive the top covers 42 of multiple sub-iron removers 4 to synchronously lift and lower in the vertical direction through telescoping, so as to open or close the top cover 42. During the process of the first telescopic mechanism 1 driving the top cover 42 to open, it can drive the first magnetic bar 44 to be withdrawn from the first filtering channel 413 and drive the second magnetic bar 45 to be withdrawn from the second filtering channel 414. Finally, the dirt scraping device 43 is used to scrape off the magnetic substances (iron) adsorbed by the first magnetic bar 44 and the second magnetic bar 45, realizing the cleaning of magnetic substances and avoiding blockage in the cylinder body 41 due to excessive magnetic substances.
[0048] In the embodiment of the present utility model, a first filtering channel 413 and a second filtering channel 414 are arranged in the cylinder body 41. The lower end of the cylinder body 41 is provided with a liquid inlet 411 communicating with the first filtering channel 413, and a liquid outlet 412 communicating with the second filtering channel 414. The upper end of the first filtering channel 413 is communicated with the upper end of the second filtering channel 414. The liquid outlet 412 is communicated with the liquid inlet 411 of another sub-iron remover 4 through a connecting pipe 3. The top cover 42 is detachably and sealingly connected to the top of the cylinder body 41. The first magnetic bar 44 is arranged in the first filtering channel 413, and the second magnetic bar 45 is arranged in the second filtering channel 414. The upper ends of the first magnetic bar 44 and the second magnetic bar 45 are connected to the top cover 42. A scraping device 43 for scraping the magnetic substances adsorbed by the first magnetic bar 44 and the second magnetic bar 45 is arranged on the top cover 42. The extending end of the first telescopic mechanism 1 is connected to the top covers 42 of a plurality of sub-iron removers 4 through a connecting plate 2, and the top covers 42 of the plurality of sub-iron removers 4 are driven by the first telescopic mechanism 1 to synchronously lift in the vertical direction, so as to drive the first magnetic bar 44 and the second magnetic bar 45 to lift in the vertical direction. Through the iron remover disclosed above, since a single sub-iron remover 4 can perform iron removal on the liquid twice, the whole iron remover not only has a simple structure and can realize multi-stage filtering and iron removal, but also when it is necessary to clean the magnetic substances adsorbed by the first magnetic bar 44 and the second magnetic bar 45, only by lifting the top cover 42 through the first telescopic mechanism 1, the magnetic substances adsorbed by the first magnetic bar 44 and the second magnetic bar 45 can be removed by the scraping device 43. Therefore, compared with the existing series-connected iron remover, the iron remover of the present application is simple to operate and has a smaller volume.
[0049] Specifically, the number of the sub-iron removers 4 is two, and the first telescopic mechanism 1 is arranged between the two sub-iron removers 4.
[0050] It should be noted that the number of the sub-iron removers 4 can be two or more, and those skilled in the art can select according to needs. In the present application, it is preferred that the number of the sub-iron removers 4 is two.
[0051] It should also be noted that when the first telescopic mechanism 1 is arranged between the two sub-iron removers 4, and then the extending end of the first telescopic mechanism 1 is connected to the top covers 42 of the two sub-iron removers 4 through the connecting plate 2, the two ends of the connecting plate 2 can be respectively connected to the top covers 42 of the two sub-iron removers 4, and the extending end of the first telescopic mechanism 1 is connected to the middle of the connecting plate 2. Then when the telescopic mechanism drives the top cover 42 to lift through the connecting plate 2, the two ends of the connecting plate 2 are evenly stressed.
[0052] Further, the scraping device 43 includes: a second telescopic mechanism 431, a scraping push plate 432, a plurality of first scraping rings 433 and a plurality of second scraping rings 434:
[0053] The second telescopic mechanism 431 is arranged on the top cover 42;
[0054] The scraping push plate 432 is provided with a plurality of first through holes for the first magnetic bar 44 to pass through and a plurality of second through holes for the second magnetic bar 45 to pass through;
[0055] The extending end of the second telescopic mechanism 431 is connected to the scraping push plate 432, and the second telescopic mechanism 431 is used to drive the scraping push plate 432 to reciprocate vertically;
[0056] The first scraping ring 433 is arranged below the first through hole and is used to scrape off the magnetic substances adsorbed by the first magnetic bar 44;
[0057] The second scraping ring 434 is arranged below the second through hole and is used to scrape off the magnetic substances adsorbed by the second magnetic bar 45.
[0058] It should be noted that the second telescopic mechanism 431 is arranged on the top cover 42, and the extending end of the second telescopic mechanism 431 is connected to the scraping push plate 432. Then, when the second telescopic mechanism 431 extends outwards, it can drive the first scraping ring 433 to scrape off the magnetic substances adsorbed by the first magnetic bar 44 and the second scraping ring 434 to scrape off the magnetic substances adsorbed by the second magnetic bar 45.
[0059] Specifically, the second telescopic mechanism 431 and / or the first telescopic mechanism 1 is any one of a cylinder, a hydraulic cylinder, and an electric push rod.
[0060] It should be noted that the second telescopic mechanism 431 can be a cylinder, or a hydraulic cylinder or an electric push rod, or other mechanisms that can drive the scraping push plate 432 to move up and down. Those skilled in the art can select according to needs;
[0061] The first telescopic mechanism 1 can be a cylinder, or a hydraulic cylinder, or other mechanisms that can drive the scraping push plate 432 to move up and down. Those skilled in the art can select according to needs;
[0062] It is worth noting that the first telescopic mechanism 1 and the second telescopic mechanism 431 of the present application can be telescopic mechanisms of different types. For example, the first telescopic mechanism 1 is a hydraulic cylinder and the second telescopic mechanism 431 is a cylinder; or they can be telescopic mechanisms of the same type. For example, the first telescopic mechanism 1 and the second telescopic mechanism 431 of the present application can be set as the same cylinder, hydraulic cylinder, etc. Those skilled in the art can select according to needs.
[0063] Specifically, the first magnetic bar 44 is the same as the second magnetic bar 45;
[0064] The first magnetic bar 44 includes: a magnetic section and a non-magnetic section;
[0065] The non-magnetic section is located below the magnetic section.
[0066] It should be noted that in this application, the first magnetic rod 44 and the second magnetic rod 45 are set to be the same, and the first magnetic rod 44 is set with a magnetic section and a non-magnetic section; and the non-magnetic section is located below the magnetic section. Thus, when the second telescopic mechanism 431 drives the scraping and dirt pushing plate 432 to move downward along the axial direction of the first magnetic rod 44, when the scraping and dirt pushing plate 432 moves to the non-magnetic section, the magnetic substances will fall under the action of their own gravity, thereby realizing the scraping of the magnetic substances.
[0067] Specifically, it further includes: a vertical partition plate 46;
[0068] The vertical partition plate 46 is arranged inside the cylinder body 41 to form a first filtering channel 413 and a second filtering channel 414.
[0069] It should be noted that when the vertical partition plate 46 is arranged inside the cylinder body 41, both sides of the vertical partition plate 46 are hermetically connected to the inner wall of the cylinder body 41.
[0070] Furthermore, the iron remover further includes: a slag receiving tray 47;
[0071] The slag receiving tray 47 can be detachably arranged on the top of the cylinder body 41 when the scraping device 43 scrapes the magnetic substances adsorbed by the first magnetic rod 44 and the second magnetic rod 45.
[0072] It should be noted that by detachably arranging the slag receiving tray 47 on the top of the cylinder body 41, when the scraping device 43 scrapes the magnetic substances adsorbed by the first magnetic rod 44 and the second magnetic rod 45, arranging the slag receiving tray 47 on the top of the cylinder body 41 can effectively collect the magnetic substances scraped by the scraping device 43, and effectively prevent the magnetic substances from falling into the first filtering channel 413 and the second filtering channel 414.
[0073] Furthermore, the iron remover further includes: a support frame 5 for fixing a plurality of sub-iron removers 4.
[0074] It should be noted that by providing the support frame 5 for fixing a plurality of sub-iron removers 4, it is convenient to move the whole iron remover.
[0075] Furthermore, the iron remover further includes: rollers 6 arranged at the bottom of the support frame 5.
[0076] It should be noted that by arranging the rollers 6 at the bottom of the support frame 5, it can further facilitate the overall movement of the iron remover.
[0077] Furthermore, the iron remover further includes: a clamp;
[0078] The clamp is used for the sealing between the cylinder body 41 and the top cover 42.
[0079] It should be noted that the top cover 42 is sealed with the cylinder body 41 through a clamp, which can not only ensure the sealing performance between the cylinder body 41 and the top cover 42, but also facilitate the separation of the top cover 42 from the cylinder body 41 when it is necessary to clean the first magnetic bar 44 and the second magnetic bar 45.
[0080] It should also be noted that the top cover 42 can be sealed with the cylinder body 41 through a clamp, or the sealing between the top cover 42 and the cylinder body 41 can be achieved by means such as bolts. Those skilled in the art can make conventional replacements according to requirements.
[0081] Preferably, the clamp includes a clamp locking screw, a clamp locking handwheel and a clamp hinge.
