Description

Technical Field

[0001] The utility model relates to a rotary iron remover, in particular to a rotary iron remover with a self-cleaning function. Background Art

[0002] The rotary iron remover is a device improved from the grid iron remover. Its main function is to solve the problems of bridging and blocking caused by the traditional grid iron remover when filtering powder materials with poor fluidity. The rotary iron remover has a wide range of applications, such as food, food additives, pharmaceuticals, fine chemicals, lithium battery positive and negative electrode materials, pigments, carbon black, flame retardants and other industry production lines. The rotary iron remover drives the annular grid to rotate through the reduction motor, thereby effectively avoiding bridging and blocking of materials when flowing through the iron remover, and efficiently removing iron impurities in loose agglomerated materials.

[0003] One disadvantage of the existing rotary iron remover compared to the grid iron remover is that it cannot be self-cleaning like the grid iron remover. Since the rotary iron remover needs to be equipped with an additional reduction motor to rotate the magnetic rod group, there is no extra space to install a scraping device and a core and jacket separation device. The existing rotary iron remover must be cleaned manually, and the iron removal efficiency is low. For this reason, the applicant has redesigned a rotary iron remover with a new structure to enable it to have a self-cleaning function. Utility Model Content

[0004] The utility model aims at the deficiencies in the prior art and provides a self-cleaning rotary iron remover. The utility model adopts a structure in which a cleaning device is sleeved in a rotary iron removing device. Then, the cleaning device is moved relative to the rotary iron removing device through the stroke difference caused by the different strokes of the rotary iron removing device and the cleaning device, so that the iron impurities on the magnetic rod are scraped off, thereby solving the problem that the rotary iron remover cannot self-clean.

[0005] In order to solve the above technical problems, the utility model solves them through the following technical solutions: a self-cleaning rotary iron remover, comprising a filter chamber and a cleaning chamber, a rotary iron removal device movable to the cleaning chamber is arranged in the filter chamber, the rotary iron removal device comprises a rotating body and a rotating motor driving the rotating body to rotate, a plurality of magnetic bars are evenly arranged on the rotating body along the circumferential direction, a cleaning device is sleeved on the magnetic bars, the rotating body is connected to a rotating body moving device, the cleaning device is connected to a cleaning device moving device, and the moving stroke of the rotating body is greater than the moving stroke of the cleaning device.

[0006] In the above technical solution, preferably, a moving channel is provided between the filter chamber and the cleaning chamber, a sealing plate is provided on the moving channel, and the rotating motor is fixed on the sealing plate and is located at one side of the cleaning chamber.

[0007] In the above technical solution, preferably, the rotating body includes a fixed disk connected to the rotating motor, the magnetic bars are evenly arranged on the fixed disk along the circumferential direction, and a fixed ring is also arranged on the other side of the magnetic bars relative to the fixed disk.

[0008] In the above technical solution, preferably, a plurality of control guide rods are arranged in the cleaning chamber, the sealing plate is arranged on the control guide rods, and the rotating body moving device controls the sealing plate to move on the control guide rods.

[0009] In the above technical solution, preferably, the rotating body moving device is a rotating body control cylinder.

[0010] In the above technical solution, preferably, the cleaning device comprises a scraper ring, on which a plurality of through holes cooperating with the magnetic rods are evenly arranged along the circumferential direction, and a cleaning stop ring is arranged on the through hole.

[0011] In the above technical solution, preferably, an extension rod is provided on the scraper ring, and the extension rod is connected to the scraper ring moving device.

[0012] In the above technical solution, preferably, the scraper ring moving device is a scraper ring cylinder, and a shift ring cooperating with the extension rod is arranged on the top of the scraper ring cylinder.

[0013] In the above technical solution, preferably, the tip of the magnetic rod is a non-magnetic area.

[0014] The cleaning of the existing magnetic rod mainly increases the length of the magnetic rod so that the magnetic core can move inside the magnetic rod to distinguish between the magnetic area and the non-magnetic area and to clean it. When the original magnetic area becomes a non-magnetic area, the adsorbed iron impurities fall off by themselves. However, the magnetic rod of the rotating iron removal device needs to be connected to a rotating motor, and there is no space to set a stretching device that allows the magnetic core inside the magnetic rod to move, so the rotating iron remover cannot be cleaned by setting up the extra-long magnetic area and the non-magnetic area. For this reason, the present application uses a scraper ring to clean the surface of the magnetic rod. In the present application, two-end stroke settings are set, one section is the stroke setting of the rotating iron removal device, and the other section is the stroke setting of the cleaning device. If self-cleaning is to be performed, the iron remover must be divided into a filter chamber and a cleaning chamber to avoid cross contamination. Therefore, the rotating iron removal device must be able to move in the filter chamber and the cleaning chamber, and the cleaning device in the cleaning chamber scrapes the magnetic rod, and the cleaning device in the filter chamber does not affect the magnetic rod filtration. For this reason, the stroke of the rotating iron removal device and the stroke of the cleaning device in the present application are inconsistent, and the stroke of the rotating iron removal device is longer than that of the cleaning device, that is, when both move from the filter chamber to the cleaning chamber, the rotating iron removal device and the cleaning device move into the cleaning chamber at the same time, and then the cleaning device stops, and the rotating iron removal device continues to move. During the process of the rotating iron removal device continuing to move, the cleaning device scrapes off the iron impurities on the magnetic rod. Then the rotating iron removal device and the cleaning device return to the filtering position again.

[0015] Compared with the prior art, the present application adopts a structure in which a cleaning device is installed in a rotating iron removal device, and then the cleaning device is moved relative to the rotating iron removal device through the stroke difference caused by the different strokes of the rotating iron removal device and the cleaning device, so that the iron impurities on the magnetic rod are scraped off, thereby solving the problem that the previous rotating iron remover cannot clean itself.

[0029] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the various embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments described in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1, as Figures 1 to 13As shown: A self-cleaning rotary iron remover comprises a filter chamber 1 and a cleaning chamber 2, wherein the filter chamber 1 is also provided with a feed port 11, a discharge port 12, and a control cabinet 13. The cleaning chamber 2 is provided with a waste port 21, a warning light 22, and an inspection port 23. The filter chamber 1 is provided with a rotary iron remover 4 movable to the cleaning chamber 2, wherein the rotary iron remover 4 comprises a fixed disk 41, which is rotated by a rotating motor 3, and the fixed disk 41 is connected to the rotating motor 3 via a transmission shaft 44. The magnetic rods 42 are evenly arranged on the fixed disk 41 along the circumferential direction, and a fixed ring 43 is also arranged on the other side of the magnetic rods 42 relative to the fixed disk 41, wherein the fixed ring 43 is fixedly connected to the tops of all the magnetic rods 42, and the fixed ring 43 and the fixed disk 41 start the function of supporting the magnetic rods 42 together, i.e., all the magnetic rods are fixed at both ends, and even if they are impacted by materials during rotation, there will be no deviation that affects the overall operation. The tip of the magnetic rod is a non-magnetic area, i.e., there is no magnetic core here. A moving channel is provided between the filter chamber 1 and the cleaning chamber 2, and a sealing plate 24 is provided on the moving channel, and the sealing plate 24 plays a role of sealing between the filter chamber 1 and the cleaning chamber 2 during filtration. The rotating motor 3 is fixed on the sealing plate 24 and is located on one side of the cleaning chamber 2. A plurality of control guide rods 25 are provided in the cleaning chamber 2, and the sealing plate 24 is provided on the control guide rod 25 and moves on the control guide rod 25 through the rotating body control cylinder 31. The setting of a plurality of control guide rods 25 can ensure the stability of the rotating iron removal device 4 during horizontal movement.

[0031] The cleaning device 5 includes a scraper ring 51, on which a plurality of through holes 55 matching the magnetic rod 42 are evenly arranged along the circumferential direction, and a cleaning gear ring 56 is arranged on the through hole 55. The magnetic rod 42 is sleeved in the through hole 55 and in close contact with the cleaning gear ring 56. An extension rod 54 is arranged on the scraper ring 51, and the extension rod 54 is connected to the scraper ring cylinder 53. The top of the scraper ring cylinder 53 is provided with a shifting ring 52 matching the extension rod 54, that is, the moving disk of the extension rod 54 is buckled in the groove of the shifting ring 52. The shifting ring 52 and the moving disk of the extension rod 54 do not contact each other during filtering. This arrangement is to reduce the resistance of the rotating iron removal device 4 during filtering. The shifting ring 52 will contact the extension rod 54 only when it moves horizontally, thereby driving the cleaning device 5 to move.

[0032] When in use, the cleaning device 5 and the main body of the rotating iron removal device 4 are both located in the filter chamber 1. At this time, the rotating motor 3 is turned on to rotate the fixed disk 41, and then the material enters from the feed port 11, and the iron impurities are adsorbed on the rotating magnetic rod 42, and the remaining material is discharged from the discharge port 12. After the magnetic rod 42 adsorbs a certain amount of iron impurities or after a certain period of time, the filtration is stopped and the magnetic rod cleaning is prepared. At this time, the feed port 11 stops feeding, the rotating motor 3 stops rotating, and the scraper ring cylinder 53 and the rotating body control cylinder 31 operate simultaneously to move the cleaning device 5 and the rotating iron removal device 4 toward the cleaning chamber 2. When the main body of the rotating iron removal device 4 enters the cleaning chamber 2, that is, the scraper ring 51 is in the cleaning chamber 2, the scraper ring cylinder 53 stops running, and the scraper ring 51 stops in the cleaning chamber 2. At this time, the rotating body control cylinder 31 continues to run, and the rotating iron removal device 4 continues to move into the cleaning chamber 2. At this time, the magnetic bar 42 and the cleaning gear ring 56 move relative to each other. At this time, the iron impurities on the magnetic bar 42 are scraped by the cleaning gear ring 56. During the scraping process, some iron impurities fall off, and some iron impurities accumulate in the non-magnetic area at the tip of the magnetic bar. When the rotating iron removal device 4 stops running, the scraping ring cylinder 53 is started to let the cleaning device 5 retreat and then advance to the current position, so that the shift ring 52 and the extension rod 54 just do not touch, and then the rotating motor 3 is started to let the fixed disk 41 rotate one circle. During the rotation of the fixed disk 41, the iron impurities located in the non-magnetic area of ​​the magnetic bar 42 naturally fall off, and the entire magnetic bar is cleaned quickly. After the magnetic bar is cleaned, the cleaning device 5 and the rotating iron removal device 4 return to the filter chamber.

[0033] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the specification of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any way.
