[0001] This utility model relates to the field of sheet metal production equipment technology, and in particular to a horizontal slag remover for sheet metal production lines. Background Technology

[0002] Slag removers are crucial equipment in the slurry preparation section of board production lines. They are used to filter the slurry after preparation, removing large particles of impurities to ensure board quality from the source and reduce the appearance of "white spots" on the finished boards. Currently, most slag removers used in calcium silicate board production lines are vertical, employing belt pulleys to drive impellers to agitate the slurry before filtering through screens, which typically have round holes. As filtration proceeds, filter residue easily adheres to the screen, causing blockages and accumulating material within the filtration chamber, making cleaning difficult and affecting filtration efficiency and ultimately the quality of the finished boards. Therefore, a horizontal slag remover for board production lines is urgently needed to address these issues. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. In the accompanying drawings, the dimensions and relative dimensions of certain parts may be enlarged for clarity.

They are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

Additionally, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0024] As per the instruction manual Figure 1-5 As shown, this utility model provides a horizontal slag remover for a board production line, including a frame 1 and a filter housing 2 mounted on the frame 1, and a horizontally arranged filter cylinder 3. The filter cylinder 3 is disposed inside the filter housing 2, and has an inlet and a slag outlet at both ends. The filter cylinder 3 is inclined downwards from the inlet to the slag outlet. The bottom of the filter housing 2 has a discharge outlet 21. The filter cylinder 3 is connected to a drive unit 4 for driving its rotation, and a cleaning mechanism 5 is provided above the filter cylinder 3.

[0025] Specifically, the slurry to be filtered enters the filter cylinder 3 through the feed inlet. The filter cylinder 3 rotates under the action of the drive unit 4, and the slurry enters the filter housing 2 through the filter holes of the filter cylinder 3, and then enters the next stage through the discharge port 21. Filter residue is retained inside the filter cylinder 3. The filter cylinder 3 is tilted, and the filter residue gradually gathers towards the discharge port and is discharged from there. Using a rotatable filter cylinder 3 effectively increases the filtration area, reduces the risk of clogging, and improves filtration efficiency. Furthermore, the tilted design of the filter cylinder 3, which allows the filter residue to gradually gather towards the discharge port, further reduces the risk of mesh clogging.

[0026] Preferably, the filter housing 2 is provided with an observation window 22 for observing the filtration status inside the housing.

[0027] Preferably, the upper part of the frame 1 is provided with a mounting surface, which is inclined and the height of the end facing the slag outlet is lower than the height of the end facing the feed inlet. The drive unit 4 is set on the mounting surface of the frame 1, and the filter cylinder 3 is supported on the mounting surface of the frame 1. The drive unit 4, the filter housing 2 and the filter cylinder 3 are inclined together with the mounting surface of the frame 1 so that the slurry to be filtered can flow along the axial direction of the filter cylinder 3 while the filter cylinder 3 rotates, thereby extending the filtration path, improving the fluidity of the slurry and thus improving the filtration efficiency. In addition, the filter residue trapped in the filter cylinder 3 will gather towards the slag outlet, which can reduce the accumulation of filter residue at the front end and middle of the filter cylinder 3, and improve the filtration effect while discharging the residue.

[0028] In an optimized implementation, the inclination angle of the mounting surface of the frame 1 is 3-7°, that is, the inclination angle of the filter screen cylinder 3 is 3-7°, to improve the fluidity of the slurry to be filtered and the filter residue. Preferably, the inclination angle of the mounting surface of the frame 1 is 3-5°.

[0029] In an optimized implementation, the filter cylinder 3 includes a first rotating section 31, a filter section, and a second rotating section 32. The first rotating section 31 and the second rotating section 32 are detachably connected to both ends of the filter section. The filter section has filter holes in its cylinder wall for slurry filtration. The filter section is located in the middle of the filter cylinder 3. The cylinder walls of the first rotating section 31 and the second rotating section 32 are solid cylinder walls, used for support on the frame 1 and for connection with the filter section. The feed inlet is located on the first rotating section 31 and connected to a feed pipe 33. The slag outlet is located at the end of the filter section near the second rotating section 32 and connected to a slag receiving hopper 34. The drive unit 4 is connected to the first rotating section 31 for transmission.

[0030] The filter cylinder 3 is cylindrical and can rotate under the action of the drive unit 4. Its central section is a filter segment, and the cylinder wall of the filter segment has filter holes to filter the slurry to be filtered. Different particle sizes of the slurry require different pore sizes. To meet the needs of different slurry applications, the filter cylinder 3 is equipped with multiple filter segments, each with different filter hole specifications. The first rotating cylinder segment 31 and the second rotating cylinder segment 32 are selectively connected to one of the filter segments to ensure that each slurry is filtered under the most suitable filter segment, guaranteeing the filtration effect and the quality of the finished product.

[0031] In an optimized implementation, the filter segment is a slit filter segment, and the filter holes of the filter segment are strip-shaped, which can be oblong holes, elliptical holes, or slit holes. Compared with circular holes, it has a larger effective opening ratio and flow area, which can improve filtration efficiency and reduce the risk of filter hole clogging.

[0032] Specifically, the filter screen segments are connected to the corresponding first rotating cylinder segment 31 and second rotating cylinder segment 32 via bolts. The filter screen segments are supported on the mounting surface of the frame 1 via the first rotating cylinder segment 31 and second rotating cylinder segment 32, and the bolt connection facilitates the disassembly and replacement of the filter screen segments. The feed inlet is located on the first rotating cylinder segment 31 and is connected to a feed pipe 33. The feed pipe 33 is connected to the middle of the first rotating cylinder segment 31 and is connected to the first rotating cylinder segment 31 via a bearing. The slag outlet is located at the end of the filter screen segment near the second rotating cylinder segment 32 and is connected to a slag receiving hopper 34. The filter slag trapped in the filter screen segment gathers at the slag outlet and is collected and processed by the slag receiving hopper 34. The drive unit 4 is connected to the first rotating cylinder segment 31 for transmission.

[0033] Preferably, a first bracket 11 is provided on the mounting surface of the frame 1, and the feed pipe 33 is fixed on the first bracket 11.

[0034] In an optimized implementation, the frame 1 is provided with a first roller group 12 and a second roller group 13. The first rotating cylinder section 31 is disposed on the first roller group 12, and the second rotating cylinder section 32 is disposed on the second roller group 13. The first roller group 12 includes two first rollers, the axial direction of each first roller is parallel to the axial direction of the filter cylinder 3, and the first rollers can rotate with the first rotating cylinder section 31. The second roller group 13 includes two second rollers, the axial direction of each second roller is parallel to the axial direction of the filter cylinder 3, and the second rollers can rotate with the second rotating cylinder section 32.

[0035] In one specific embodiment, one of the first rollers of the first roller group 12 serves as the drive roller 14. The drive unit 4 includes a reducer 41 and a coupling 42, both of which are mounted on the mounting surface of the frame 1. The reducer 41 is connected to the drive roller 14 via the coupling 42, providing power to the drive roller 14. The drive roller 14 drives the first rotating cylinder section 31 to rotate via friction transmission, thereby driving the filter screen section to rotate. The drive unit 4 adopts a single-sided drive, with the reducer 41 driving the drive roller 14 to rotate via the coupling 42. The friction transmission allows the drive roller 14 to drive the first rotating cylinder section 31 to rotate, resulting in smoother transmission.

[0036] In an optimized implementation, the first rotating cylinder section 31 and / or the second rotating cylinder section 32 are equipped with a limiting wheel assembly. Specifically, the limiting wheel assembly includes a first pressure roller 15 and a second pressure roller 16. Both the first pressure roller 15 and the second pressure roller 16 are located at the upper end of the frame 1. The first pressure roller 15 is located directly above the first rotating cylinder section 31, and its axial direction is parallel to that of the first rotating cylinder section 31. The first pressure roller 15 can radially limit the first rotating cylinder section 31, preventing it from moving vertically. The second pressure roller 16 is located directly above the second rotating cylinder section 32, and its axial direction is parallel to that of the second rotating cylinder section 32. The second pressure roller 16 can radially limit the second rotating cylinder section 32, preventing it from moving vertically.

[0037] Preferably, the limiting wheel assembly further includes a first guide wheel 17 and a second guide wheel 18. The first guide wheel 17 and the second guide wheel 18 are mounted on the upper side of the frame and cooperate with the first rotating cylinder section 31 to limit the axial movement of the first rotating cylinder section 31 and prevent it from shaking. The first rotating cylinder section 31 is provided with an circumferential groove that matches the guide wheel, which can limit the axial movement of the first rotating cylinder section 31.

[0038] In an optimized implementation, the cleaning mechanism 5 includes a spray head 51 and a water receiving tank 52 for collecting spray water. The spray head 51 is located above the filter screen cylinder 3 and the spray direction is towards the filter screen cylinder 3. To avoid interference with the pressure roller, the spray head 51 is positioned at a 60° angle to the side above the filter screen cylinder 3. The spray head 51 includes multiple nozzles spaced apart along the axial direction of the filter screen cylinder 3. Each nozzle can spray washing water to clean the filter screen segment and remove filter residue adhering to the filter screen segment in a timely manner. The nozzles are preferably low-pressure fan-shaped nozzles. The spray head 51 is connected to a spray pipe for supplying water or washing liquid. The water receiving tank 52 is located inside the filter screen cylinder 3 and directly below the spray head 51. A drain pipe 53 is connected to the outside of the water receiving tank 52. The water receiving tank 52 is located directly below the spray head 51 and can collect spray water. The spray water is discharged through the drain pipe 53. The flow paths of the spray water and the slurry to be filtered are set separately to avoid the spray water from mixing into the slurry to be filtered and affecting the slurry concentration.

[0039] As one specific implementation, the spray head 51 and the water receiving tank 52 are arranged above the feed inlet, which can ensure that the cleaning process does not affect the slurry filtration. During the filtration process, the filter cylinder 3 can be cleaned at the same time without interrupting the filtration operation due to the cleaning of the filter cylinder 3.

[0040] Preferably, the drain pipe 53 can be connected to the slag receiving hopper 34.

[0041] In an optimized implementation, a second bracket 19 is provided on the mounting surface of the frame 1, and the water receiving tank 52 is disposed on the second bracket 19.

[0042] In an optimized implementation, the cleaning mechanism further includes a drying component, which comprises an air knife 54 and a fan 55. The air knife 54 is positioned directly above the filter cylinder 3 and adjacent to the spray head 51. The air knife 54 is connected to the fan 55, and it dries the filter cylinder 3. The self-cleaning of the filter cylinder 3 is achieved through the spray head 51 and the air knife 54. The air knife 54 is located directly above the water receiving tank 52, allowing liquid blown off by the air knife to be collected in the water receiving tank, preventing it from falling into the slurry to be filtered and affecting its concentration.

[0043] During use, as the filter cylinder 3 rotates, the air knife 54 is positioned downstream of the spray head 51, meaning that the area of ​​the filter cylinder 3 after being sprayed rotates to the area below the air knife 54 for air drying, thus achieving self-cleaning of the filter cylinder 3.

[0044] In summary, this utility model provides a horizontal slag remover for filtering slurry in the slurry preparation stage. It adopts a single-sided drive, with the reducer 41 driving the drive wheel 14 to rotate via the coupling 42; it also adopts friction transmission, with the drive wheel 14 driving the first rotating cylinder section 31 to rotate; the filter screen section is bolted to the first rotating cylinder section 31 and the second rotating cylinder section 32 for easy disassembly and replacement; the slurry enters the filter screen section from the feed inlet, and the filtered slurry enters the next stage from the discharge outlet 21 at the bottom.
