Description

Technical Field

[0001] This utility model relates to a geological and mineral processing tool, and more specifically, a sieve for screening slag. Background Technology

[0002] Currently, mainstream slag screens use flat screen plates. While these allow fine slag to pass through and coarse slag to be retained, they have significant drawbacks in the collection and disposal of large slag pieces. Because the screen plate is planar, large slag pieces disperse across the entire screen surface during screening due to vibration or manual pushing, lacking a fixed aggregation area or guiding structure. During dumping, the dispersed slag slides in any direction, easily falling out of the collection container, reducing collection efficiency, increasing on-site cleanup workload, and even posing safety hazards. In summary, existing screens, due to structural defects, restrict screening efficiency and increase costs, necessitating a screen structure that can guide large slag pieces to be dumped in a concentrated manner. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides a sieve for screening slag, the beneficial effect of which is that this utility model can guide large pieces of slag to be poured out in a concentrated manner.

[0004] A sieve for screening slag includes a sieve plate with a plurality of sieve holes evenly distributed on the sieve plate, and an arc-shaped portion in the middle of the sieve plate, the arc-shaped portion being concave downward.

[0005] Baffles are fixed on both the front and rear sides of the sieve plate.

[0006] A connecting post is fixed between the left and right ends of the two baffles.

[0007] The upper parts of the two rotating doors are hinged to two connecting columns, and the two rotating doors block the left and right sides of the screen plate respectively.

[0008] Both ends of the front baffle are fixed with protrusions, and each protrusion is connected with a stop screw by thread. The two stop screws are respectively blocked on the outside of the two revolving doors.

[0009] A pivot is fixed to the middle of the outer side of each of the two baffles.

[0010] The two shafts are rotatably connected to the upper part of the two L-shaped frames via bearing seats.

[0011] A motor is fixed on one of the L-shaped frames, and the output shaft of the motor is connected to one of the rotating shafts via a coupling.

[0012] The lower horizontal portions of the two L-shaped frames are slidably connected to the front and rear ends of the base, respectively. The front and rear ends of the upper side of the base are fixed with protruding plates, and each protruding plate is fixed with a compression spring. The other ends of the two compression springs are respectively fixed to the vertical portions of the two L-shaped frames.

[0013] A handle is fixed to the L-shaped frame located on the front side. Attached Figure Description

[0024] like Figure 1-2 As shown;

[0025] A slag screening sieve includes a sieve plate 1 with multiple sieve holes 2 evenly distributed on the sieve plate 1. An arc-shaped part 3 is provided in the middle of the sieve plate 1, and the arc-shaped part 3 is concave downward. The concave design of the arc-shaped part 3 creates a certain arc drop on the sieve surface. Large pieces of slag that are screened out will remain on the upper side of the sieve plate 1, and the large pieces of slag that are screened out will gather at the lowest position of the arc-shaped part 3. At this time, the sieve plate 1 can be tilted left and right, and the large pieces of slag that are screened out will be poured out in a gathered state, so as to avoid the large pieces of slag that are screened out not being gathered enough when poured out, causing the slag to scatter.

[0026] like Figure 6-7 As shown;

[0027] Since baffles 8 are fixed on both the front and rear sides of the screen plate 1, the slag will flow on the screen plate 1 under vibration or gravity during the slag screening process. The baffles 8 on the front and rear sides of the screen plate 1 can form a longitudinal shielding structure, which can effectively prevent the slag from sliding off the front and rear edges of the screen plate 1 during the flow, thus avoiding material waste caused by longitudinal scattering of slag.

[0028] like Figure 6 As shown;

[0029] Since connecting columns 7 are fixed between the left and right ends of the two baffles 8, and the connecting columns 7 are connected to the left and right ends of the two baffles 8, on the one hand, it can enhance the structural stability of the two baffles 8 and avoid the baffles 8 from deforming or shifting due to slag impact or screen vibration during the screening process; on the other hand, it provides a fixed support point for the subsequent installation of the rotating door 6, so that the rotating door 6 can be stably hinged to the connecting columns 7.

[0030] like Figure 6-7 As shown;

[0031] Since the upper parts of the two rotating doors 6 are hinged to the two connecting columns 7 respectively, and the two rotating doors 6 block the left and right sides of the screen plate 1 respectively, during the screening operation, the two rotating doors 6 are in a closed state, blocking the left and right sides of the screen plate 1, forming a closed screening space together with the front and rear baffles 8. This prevents the slag from overflowing from the left and right sides of the screen plate 1 during the screening process, ensuring that all the slag is screened on the screen plate 1. When it is necessary to pour out large pieces of slag, the rotating doors 6 can be rotated upward around the connecting columns 7 to open the outlet on the corresponding side of the screen plate 1. With the screen plate 1 tilted, the accumulated large pieces of slag can be concentrated and flowed out from the opened side opening along the arc surface, avoiding the slag from scattering during the pouring process and improving the pouring efficiency.

[0032] like Figure 6 As shown;

[0033] Since both ends of the front baffle 8 are fixed with protrusions 4, and each protrusion 4 is threaded with a stop screw 5, the two stop screws 5 respectively block the outside of the two rotating doors 6. Before screening, the stop screws 5 are rotated to make their ends press against the outside of the rotating door 6, thus limiting and fixing the rotating door 6 and preventing the rotating door 6 from opening accidentally due to screen vibration or slag impact. This ensures that the screening space remains closed during the screening process and prevents slag from overflowing. When it is necessary to open the rotating door 6 to pour material, the stop screws 5 are rotated in the opposite direction to disengage their ends from the rotating door 6, releasing the limitation on the rotating door 6. The rotating door 6 can then be easily rotated. The operation is convenient and the fixation is reliable, effectively ensuring the stability of the screening and pouring process.

[0034] like Figure 8 As shown;

[0035] Since the two baffles 8 are both fixed with a rotating shaft 10 at the middle of their outer sides, the rotating shaft 10 provides rotational support for the screen plate 1, allowing the screen plate 1 to tilt left and right around the rotating shaft 10, thus providing structural conditions for pouring out large pieces of slag.

[0036] like Figure 8 As shown;

[0037] Since the two rotating shafts 10 are rotatably connected to the upper parts of the two L-shaped frames 14 via bearing seats, the bearing seats reduce the frictional resistance between the rotating shafts 10 and the L-shaped frames 14, allowing the screen plate 1 to rotate more smoothly around the rotating shafts 10 and reducing the resistance during the tilting operation of the screen plate 1. Whether the screen plate is tilted manually or electrically, it is easier and more efficient. At the same time, the L-shaped frames 14 provide a stable support base for the screen plate 1, raising the screen plate 1 off the ground, which facilitates the placement of a fine slag collection container below. This allows the screened fine slag to fall smoothly through the screen holes 2 into the collection container, preventing the fine slag from accumulating on the ground and improving the continuity of the screening operation.

[0038] like Figure 8 As shown;

[0039] A motor 11 is fixed on one of the L-shaped frames 14, and the output shaft of the motor 11 is connected to one of the rotating shafts 10 via a coupling. The motor 11 provides power for the tilting of the screen plate 1, replacing manual tilting and reducing the intensity of manual operation. When it is necessary to unload material, the motor 11 is started, and the output shaft of the motor 11 drives the rotating shaft 10 to rotate via the coupling, thereby driving the screen plate 1 to tilt around the rotating shaft 10 to a suitable angle, so that the large pieces of slag gathered in the arc-shaped part 3 can be poured out in a concentrated manner.

[0040] like Figure 8 As shown;

[0041] Since the lower horizontal portions of the two L-shaped frames 14 are slidably connected to the front and rear ends of the base 9 respectively, and the front and rear ends of the upper side of the base 9 are fixed with protruding plates 13, each protruding plate 13 is fixed with a compression spring, and the other ends of the two compression springs are respectively fixed to the vertical parts of the two L-shaped frames 14. During the screening operation, the two L-shaped frames 14 can move back and forth on the base 9, thereby driving the two rotating shafts 10, the two baffles 8 and the screen plate 1 to move back and forth. At this time, the screen plate 1 can also be driven to tilt left and right, thereby performing multi-directional screening of the slag on the upper side of the screen plate 1, effectively screening the slag. The two compression springs can help the two L-shaped frames 14 return to their original positions after moving back and forth, thereby enabling the two L-shaped frames 14 and the screen plate 1 to move back and forth, so that the screen plate 1 can screen back and forth.

[0042] like Figure 8 As shown;

[0043] Since the L-shaped frame 14 is fixed with a handle 12, the L-shaped frame 14 can be manually driven to move back and forth on the base 9 by the handle 12, thereby driving the two rotating shafts 10, the two baffles 8 and the sieve plate 1 to move back and forth.
