Description

Technical Field

[0001] This utility model relates to the field of cement production technology, and in particular to a cement grinding suspension iron removal device. Background Technology

[0002] Cement is a major raw material in infrastructure construction, and the demand for it is large.

[0003] As a grinding system used to improve cement quality, it has seen significant improvements in recent years due to my country's increasing requirements for cement grades and advancements in cement production processes. Currently, the particle size of general cement materials is generally below 10mm. Under these conditions, impurities in the cement are difficult to detect. If chains, wrenches, bolts, scrap iron parts, or other iron debris are mixed in, they will cause serious damage to the fragile components of the fine crusher. This can range from damaging hammers, liners, and screen bars to seriously endangering critical parts such as the crusher's central shaft and bearings. This not only damages the machine and disrupts normal industrial production but can also endanger the personal safety of operators, causing incalculable losses.

[0004] Currently, vertical mill production lines typically use belt conveyors for transport. The traditional iron removal process involves installing an electromagnetic separator above the belt. However, due to insufficient magnetic force and inadequate slag dispersion, the iron filings are trapped and cannot be adsorbed. Therefore, only the iron powder at the top of the slag can be removed, while most of the iron powder at the bottom enters the subsequent process with the slag, resulting in incomplete iron removal.

[0005] Therefore, we propose a cement grinding suspension iron removal device to solve the existing problems. Utility Model Content

[0006] The purpose of this invention is to address the problems existing in the background technology by proposing a cement grinding suspension iron removal device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cement grinding suspension iron removal device, comprising a lower frame, a shell, an upper frame, and an electromagnetic block. A lower conveyor belt is driven inside the lower frame, and an upper conveyor belt is driven inside the upper frame. The electromagnetic block is located inside one end of the upper conveyor belt. The lower surface of one end of the lower frame and the upper surface of one end of the upper frame are connected to each other through the shell. A dispersing wheel is rotatably provided inside the shell. A suspension component is provided on the outer wall of the shell, and the iron removal part of the suspension component is located above the lower conveyor belt.

[0008] Preferably, the two ends of the housing are symmetrically provided with square frames, and the two square frames are respectively bolted to the lower frame and the upper frame.

[0009] Preferably, spacers are installed at equal intervals on the surfaces of both the lower and upper conveyor belts.

[0010] Preferably, the two ends of the electromagnetic block are respectively bolted to the inner walls of the two sides of the upper frame, and the width of the electromagnetic block is equal to the width of the upper conveyor belt.

[0011] Preferably, the suspension assembly consists of a roller, a base plate, a connecting plate, a scraper, a box, an electromagnetic rod core, and a bottom plate. The base plate is disposed on the outer wall of the shell, and the connecting plate is disposed at the end of the base plate.

[0012] Preferably, the base plate is located at the bottom end of the connecting plate, and the box body is inserted and placed on the upper surface of the base plate.

[0013] Preferably, the roller shaft is rotatably mounted on the substrate, one end of the electromagnetic rod core is fixed on the substrate, and the other end of the electromagnetic rod core is inserted into the roller shaft and rotatably connected to the roller shaft.

[0014] Preferably, the scraper is disposed on the base plate, and the inclined end of the scraper abuts against the outer surface of the roller.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] During use, the cement powder slag suspension iron removal device of this utility model is connected to an external power source to make the device work. The cement powder slag is transported on the upper conveyor belt. During this process, the electromagnetic block in the upper conveyor belt generates magnetic force. Under the action of magnetic attraction, the iron slag in the cement powder slag is adsorbed onto the surface of the upper conveyor belt.

[0017] As the upper conveyor belt continues to operate, the iron slag moves to a position far away from the electromagnetic block and loses its magnetic attraction. Under the action of gravity, it automatically falls off the surface of the upper conveyor belt.

[0018] After slag removal, the slag falls into the shell. At this time, the internal dispersing wheel rotates to break up the clumps of slag and then falls onto the surface of the lower conveyor belt. As the lower conveyor belt operates, the slag passes at a constant speed under the rotating roller. The electromagnetic rod core works to make the roller magnetic. Under the magnetic attraction, the iron residue in the slag is adsorbed onto the surface of the roller to complete the secondary iron removal operation. As the roller rotates and moves to the scraper, the scraper scrapes the iron residue off and falls into the box to complete the iron residue collection.

[0019] This invention designs a double-layer magnetic adsorption iron removal grinding system. Before roller pressing, the raw material is subjected to self-unloading magnetic adsorption, which initially filters out large iron minerals. Then, the raw material is dispersed to make it fluid and loose, allowing the iron particles to break through the surrounding ore for secondary magnetic adsorption. This ensures that the iron filings enter the next process at a normal level, guaranteeing the normal operation of the entire roller pressing system, improving the machine's operating time and service life.

[0027] 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.

[0028] Example 1

[0029] like Figures 1-5 As shown, the present invention proposes a cement grinding suspension iron removal device, which includes a lower frame 1, a housing 4, an upper frame 5, and an electromagnetic block 13. A lower conveyor belt 10 is driven inside the lower frame 1, and an upper conveyor belt 11 is driven inside the upper frame 5. The electromagnetic block 13 is located inside one end of the upper conveyor belt 11. The lower surface of one end of the lower frame 1 and the upper surface of one end of the upper frame 5 are connected to each other through the housing 4. A dispersing wheel 14 is rotatably provided inside the housing 4. A suspension component is provided on the outer wall of the housing 4. The iron removal part of the suspension component is located above the lower conveyor belt 10.

[0030] Based on Example 1:

[0031] During use, the cement powder suspension iron removal device of this utility model is connected to an external power source to make the device work. The cement powder slag is conveyed on the upper conveyor belt 11. During this process, the electromagnetic block 13 in the upper conveyor belt 11 generates magnetic force. Under the action of magnetic attraction, the iron slag in the slag is adsorbed onto the surface of the upper conveyor belt 11.

[0032] As the upper conveyor belt 11 continues to operate, the iron slag moves to a position away from the electromagnetic block 13 and loses its magnetic attraction. Under the action of gravity, it automatically falls off the surface of the upper conveyor belt 11.

[0033] After slag removal, the slag falls into the shell 4. At this time, the dispersing wheel 14 inside the shell 4 rotates to break up the clumps of slag and then falls onto the surface of the lower conveyor belt 10. As the lower conveyor belt 10 operates, the slag passes uniformly under the rotating roller 2. The electromagnetic rod core 15 works to make the roller 2 magnetic. Under the magnetic attraction, the iron residue in the slag is adsorbed onto the surface of the roller 2 to complete the secondary iron removal operation. As the roller 2 rotates and moves to the scraper 8, the scraper 8 scrapes the iron residue off and falls into the box 9 to complete the collection of iron residue.

[0034] Example 2

[0035] like Figures 1-5 As shown, the cement grinding suspension iron removal device proposed in this utility model, compared with the first embodiment, further includes: square frames 3 symmetrically provided at both ends of the shell 4, the two square frames 3 being bolted to the lower frame 1 and the upper frame 5 respectively, and partition strips 12 being installed at equal intervals on the surfaces of the lower conveyor belt 10 and the upper conveyor belt 11. The design of the partition strips 12 ensures that the movement direction of the iron slag is the same as the movement direction of the conveyor belt; the partition strips 12 can ensure that the slag thickness in each compartment is uniform, increase the iron removal area of ​​the iron remover, and make the iron removal effect more effective.

[0036] The two ends of the electromagnetic block 13 are respectively bolted to the inner walls of the two sides of the upper frame 5, and the width of the electromagnetic block 13 is equal to the width of the upper conveyor belt 11.

[0037] The suspension assembly consists of a roller 2, a base plate 6, a connecting plate 7, a scraper 8, a box 9, an electromagnetic rod core 15, and a base plate 16. The base plate 6 is located on the outer wall of the shell 4, the connecting plate 7 is located at the end of the base plate 6, and the base plate 16 is located at the bottom end of the connecting plate 7. The box 9 is inserted and placed on the upper surface of the base plate 16. The roller 2 is rotatably mounted on the base plate 6. One end of the electromagnetic rod core 15 is fixed on the base plate 6, and the other end of the electromagnetic rod core 15 is inserted into the roller 2 and rotatably connected to the roller 2. The scraper 8 is located on the base plate 16, and the inclined end of the scraper 8 abuts against the outer surface of the roller 2. The slag passes uniformly under the rotating roller 2. The operation of the electromagnetic rod core 15 makes the roller 2 magnetic. Under the magnetic attraction, the iron slag remaining in the slag is adsorbed on the surface of the roller 2 to complete the secondary iron removal operation. As the roller 2 rotates and moves to the scraper 8, the scraper 8 scrapes the iron slag down into the box 9 to complete the collection of the iron slag.

[0038] It should be noted that the structure of the lower conveyor belt 10, the upper conveyor belt 11, the electromagnetic block 13, and the electromagnetic rod core 15 is a mature existing technology. Its working principle and internal structure are known to those skilled in the art. This utility model only utilizes its function and does not improve its internal structure. Therefore, it will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0039] The dispersing wheel 14 and roller 2 of this utility model also need to be provided with a power device to enable them to work normally. As is well known to those skilled in the art, the provision of such power is commonplace and is a conventional means or common knowledge. It will not be described in detail here. Those skilled in the art can make any selection according to their needs or convenience.

[0040] The above specific embodiments are merely several preferred embodiments of this utility model.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
