[0029] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.
[0031] The utility model embodiment provides a scraping rake, such as Figure 1 As shown, it includes: a rake body 100, a handle 200, and a cross baffle 300. The rake body 100 has a first leakage hole 111; the handle 200 is fixed to the upper end of the rake body 100; the cross baffle 300 has a second leakage hole 310, and the cross baffle 300 is fixed to the lower end of the rake body 100 and is set at an angle to the end face of the rake body 100. The cross baffle 300 and the handle 200 are located on the same side of the rake body 100.
[0032] The slag rake and the cross baffle 300 provided in the embodiment of the utility model can, on the one hand, improve the strength of the lower end of the rake body 100, making it not easy to deform and able to withstand greater pressure. The slag rake can work stably even after it dives into the deeper aluminum liquid. On the other hand, even if the slag rake is embedded in the deeper aluminum liquid, after the slag rake is lifted, under the joint action of the cross baffle 300, the rake body 100, the first leakage hole 111 and the second leakage hole 310, the aluminum liquid will flow back into the furnace, and the slag will be retained above the cross baffle 300. Then, the slag rake is lifted to take the slag out of the furnace, so as to remove the slag in the aluminum liquid as thoroughly as possible and ensure the purity of the aluminum liquid. In addition, in the prior art, the user's proficiency is extremely high, and the body of the slag rake must be moved close to the aluminum liquid surface and towards the furnace door to reduce the carry-out of aluminum liquid. The slag rake provided by the utility model is not limited by the depth of the aluminum liquid, and does not require excessive training for the user. The user can easily master its method of use, does not need to be limited to a specific slag removal route, and can also achieve multi-directional slag removal, reducing the difficulty of operation.
[0033] Specifically, Figure 1As shown, in the embodiment of the utility model, the first leakage hole 111 has a plurality of holes, which are arranged at intervals and are all tapered holes. The large end of the first leakage hole 111 is located at the outer end surface of the rake body 100, and the outer end surface is located on the side away from the handle 200; the second leakage hole 310 has a plurality of holes, which are arranged at intervals and are all tapered holes. The large end of the second leakage hole 310 is located at the lower end surface of the horizontal baffle 300. The first leakage hole 111 and the second leakage hole 310 are set as tapered holes. During the working process, when the tapered hole is blocked, it is easy to be washed away by the aluminum liquid, thereby unblocking the tapered hole, facilitating the subsequent circulation of aluminum liquid, and realizing the self-cleaning function; in addition, the setting of the tapered hole is not easy to block the channel, so the aluminum liquid can be smoothly discharged into the furnace, thereby reducing the amount of aluminum liquid brought out by the slag rake, saving costs.
[0034] Furthermore, the first leakage hole 111 and the second leakage hole 310 are both arranged near the connection between the rake body 100 and the horizontal baffle 300, so that the aluminum liquid can flow into the furnace more easily. Specifically, the tapered holes of the first leakage hole 111 and the second leakage hole 310 are both trumpet-shaped structures, wherein the diameter of the small end hole of the tapered hole can be set to 10mm to 12mm, and the angle between the busbar and the central axis is about 10°.
[0035] In the embodiment of the utility model, Figure 1 As shown, the horizontal baffle 300 is perpendicular to the lower end portion fixedly arranged on the rake body 100. Such arrangement facilitates positioning and installation between the two.
[0036] In the embodiment of the utility model, Figure 1 As shown, the rake body 100 includes a vertical plate 110 and an oblique beam 120 fixedly arranged above the vertical plate 100, the oblique beam 120 is arranged obliquely, the handle 200 is fixedly arranged at the upper end of the oblique beam 120, the cross baffle 300 is fixedly arranged at the lower end of the vertical plate 110, the first leakage hole 111 is arranged on the vertical plate 110, and the handle 200, the oblique beam 120 and the vertical plate 110 are arranged at an obtuse angle in sequence. In this way, during use, the oblique beam 120 is not easy to scratch the furnace top or furnace wall, saving operating space, thus increasing the up and down floating space of the slag rake and reducing the difficulty of operation.
[0037] Specifically, the angle between the handle 200 and the oblique beam 120 can be set to about 135°, and the angle between the oblique beam 120 and the vertical plate 110 can be set to about 135°. The size of the handle 200 can be determined according to the length and shape of the furnace body. For example, the length of the handle 200 can be set to 4m to 5m, the diameter can be set to 100mm to 110mm, and the handle 200 can be a hollow steel pipe structure with a pipe thickness of 10mm to 15mm. This setting can not only make the handle 200 not too heavy, but also ensure the strength of the handle 200.
[0038] In the embodiment of the present invention, the inclined cross beam 120 and the cross baffle 300 are located on the same side of the vertical plate 110 .
[0039] In the embodiment of the utility model, the oblique cross beam 120 is a plate-like structure, and the end surface shape is a trapezoidal structure with a small upper part and a large lower part. The width of the oblique cross beam 120 here refers to the width of its lower end. Such a configuration can reduce the weight of the oblique cross beam 120 and can also adapt to the size of the handle 200.
[0040] In the embodiment of the utility model, the left and right sides of the lower end of the inclined cross beam 120 are respectively flush with the left and right sides of the upper end of the vertical plate 110; the left and right sides of the lower end of the vertical plate 110 are respectively flush with the left and right sides of the horizontal baffle 300. Such an arrangement makes the overall structure of the slag rake more compact.
[0041] In the embodiment of the utility model, the thickness of the inclined cross beam 120 is smaller than the thickness of the vertical plate 110 ; the thickness of the horizontal baffle 300 is smaller than the thickness of the vertical plate 110 .
[0042] Specifically, the length of the inclined cross beam 120 can be set to 450 mm to 500 mm, the width can be set to about 1000 mm, and the thickness can be set to 30 mm to 35 mm. The height of the vertical plate 110 can be set to 450 mm to 500 mm, the width can be set to about 1000 mm, and the thickness can be set to 40 mm to 45 mm. The thickness of the horizontal baffle 300 can be set to 30 mm to 35 mm, the width can be set to about 1000 mm, and the length (such as the distance from the left edge to the left end face of the vertical plate 110 in the figure) can be set to 300 mm to 350 mm.
[0043] In the embodiment of the utility model, it also includes: a reinforcing rib 400, which is located in the area surrounded by the handle 200, the oblique beam 120 and the vertical plate 110, and is fixedly connected to all three. Specifically, the reinforcing rib 400 is a plate-like structure, and its end surface is perpendicular to the end surface of the oblique beam 120. The thickness of the reinforcing rib 400 can be set to 30mm to 35mm. Such a setting is convenient for positioning and processing.
[0044] In the embodiment of the utility model, the end surface of the reinforcing rib 400 away from the oblique beam 120 is a concave arc structure, which can not only improve the connection strength between the handle 200, the oblique beam 120 and the vertical plate 110, but also reduce the weight. Specifically, the curvature radius of the arc structure can be set to 500mm to 800mm.
