Description

Technical Field

[0001] The utility model relates to the technical field of aluminum slag cleaning, in particular to a furnace cleaning shovel for a rotary furnace. Background Art

[0002] In modern life, aluminum products have become very common. However, aluminum ore resources are limited, so the reprocessing of aluminum products is imperative. After a rotary furnace calcines aluminum ingots for a period of time, impurities such as aluminum ash and aluminum slag will adhere to the inner wall of the furnace, reducing the furnace capacity and affecting product quality. At this time, it is necessary to clean the furnace slag. Currently, most cleaning methods use a furnace cleaning shovel with a flat trapezoidal shovel head. The force-bearing area of the shovel head is relatively large. When cleaning furnace slag with a relatively thick or firm caking on the furnace wall, it may be impossible to clean it. At this time, it is necessary to significantly increase the furnace temperature to soften the furnace slag before it can be easily cleaned. The operation of heating the rotary furnace will increase the production interval time and reduce production efficiency. Summary of the Invention

[0003] In order to solve the problem that the force-bearing area of the shovel head of the existing flat trapezoidal furnace cleaning shovel is relatively large, and when cleaning furnace slag with a relatively thick or firm caking on the furnace wall, it may be impossible to clean it. At this time, it is necessary to significantly increase the furnace temperature to soften the furnace slag before it can be easily cleaned. The operation of heating the rotary furnace will increase the production interval time and reduce production efficiency, the utility model provides a furnace cleaning shovel for a rotary furnace. The shovel head formed by a triangular first connecting plate and a second connecting plate with a tip can more easily clean furnace slag with a relatively thick or firm caking on the furnace wall, improving production efficiency.

[0004] To achieve the above object, the technical solution of the utility model is: a furnace cleaning shovel for a rotary furnace, including a shovel handle. A first connecting plate is provided at the front end of the shovel handle. A second connecting plate is fixed on the upper side of the first connecting plate. Both the first connecting plate and the second connecting plate are triangular plate bodies. A push plate is fixed on the lower side of the first connecting plate. The push plate is fixed on the side of the first connecting plate close to the shovel handle and is perpendicular to the shovel handle. The corner of the first connecting plate far from the shovel handle is used to press against the side wall of the rotary furnace. The corner of the second connecting plate far from the shovel handle coincides with the corner of the first connecting plate far from the shovel handle. The first connecting plate and the second connecting plate form the shovel head part of the furnace cleaning shovel. The tip of the shovel head is formed by the corner where the first connecting plate and the second connecting plate coincide. The cross-section of the first connecting plate and the second connecting plate is in an "丄" shape. The connection part between the shovel handle and the first connecting plate is located below the intersection point of the first connecting plate and the second connecting plate.

[0005] Further, the cross-section of the push plate is trapezoidal, and the two waists of the trapezoid are arc-shaped.

[0006] Furthermore, a fixing base is fixed to the rear part of the shovel handle. Fork slots are provided on both sides of the fixing base. The fork slots are used to dock the two forks of a forklift. A limiting slot is opened at the rear end of the shovel handle. The limiting slot is used to mount the shovel handle on the forklift. The fork slots are located on both sides of the limiting slot.

[0007] Furthermore, an installation frame is provided on the forklift. A "U"-shaped limiting plate is provided on the installation frame. The "U"-shaped limiting plate is inserted into the limiting slot. A first limiting hole penetrates through the limiting plate. A second limiting hole matching the first limiting hole is provided on the shovel handle above the limiting slot. A bolt is inserted through the first limiting hole and the second limiting hole to mount the shovel handle on the forklift. The limiting plate is fixed on the gantry, and the two sides of its "U" shape face the rear end of the shovel handle, and the limiting plate can be inserted into the limiting slot, facilitating the insertion of a bolt through the first limiting hole and the second limiting hole.

[0008] Furthermore, the shovel handle is detachably connected to the first connecting plate.

[0009] Furthermore, a fixing slot is provided at the front end of the shovel handle. A fixing block matching the fixing slot is fixed to one end of the first connecting plate close to the shovel handle. Fixing holes are correspondingly opened on the fixing slot and the fixing block. A bolt is inserted through the fixing holes to fix the shovel handle and the first connecting plate. The shovel head further includes a fixing block fixed on the first connecting plate. The detachable connection between the fixing block and the shovel handle realizes the convenient replacement of the shovel head.

[0010] Furthermore, the first connecting plate is an equilateral triangle plate body, the second connecting plate is a right triangle plate body, and the cross-section formed by connecting the first connecting plate and the second connecting plate and parallel to the push plate 4 is in an "丄" shape.

[0011] Furthermore, the length of each side of the first connecting plate ranges from 50 mm to 500 mm.

[0012] Furthermore, one right-angled side of the second connecting plate is equal to the median line of the first connecting plate, and the length range of the other right-angled side is from 10 mm to 150 mm.

[0013] Through the above technical solutions, the beneficial effects of the present utility model are as follows: The triangular first connecting plate and the second connecting plate of the present utility model form a shovel head with a tip. When pressing against the side wall of the rotary furnace, it is easier to break the thicker or firmer slag on the furnace wall when the forklift forks move up and down. The setting of the second connecting plate makes the cleaning of the slag easier and can strengthen the stability of the first connecting plate. The push plate adapted to the bottom plate of the rotary furnace can clean out the slag cleaned down, improving the production efficiency. After the shovel head is used for a long time, the effect of treating the slag on the furnace wall will be poor. The detachable connection between the shovel handle and the shovel head can quickly replace the shovel head, improving the working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the first connecting plate 2 is an equilateral triangle plate body, the second connecting plate 3 is a right triangle plate body. After the first connecting plate 2 and the second connecting plate 3 are connected, a cross-section parallel to the pushing plate 4 is in the shape of "丄". The cross-section of the pushing plate 4 is trapezoidal, and the two waists of the trapezoid are arc-shaped. Specifically, the length range of each side of the first connecting plate 2 is 50 mm - 500 mm. One right-angled side of the second connecting plate 3 is equal to the midline of the first connecting plate 2, and the length range of the other right-angled side is 10 mm - 150 mm. In this case, considering the sizes of different rotary furnace inner cavities and the cleaning efficiency of the furnace cleaning shovel, in this embodiment, the length of each side of the first connecting plate 2 can be 50 mm, 100 mm, 200 mm, 400 mm, and 500 mm. Among them, one right-angled side of the second connecting plate 3 coincides with the midline of the first connecting plate 2, and its size is determined by the length of each side of the first connecting plate 2. The length of the other right-angled side of the second connecting plate 3 can be 10 mm, 20 mm, 50 mm, 100 mm, 150 mm.

[0023] A fixed seat 5 is fixed to the rear part of the shovel handle 1. Fork slots 6 are provided on both sides of the fixed seat 5. The fork slots 6 are used to dock the two forks of the forklift 8. A limit slot is opened at the rear end of the shovel handle 1, and the limit slot is used to install the shovel handle 1 on the forklift 8. The fork slots 6 are located on both sides of the limit slot.

[0024] Specifically, a gantry 9 is provided on the forklift 8. A "U"-shaped limit plate 10 is provided on the gantry 9. The "U"-shaped limit plate 10 is inserted into the limit slot. A first limit hole 11 penetrates through the limit plate 10. A second limit hole 12 that matches the first limit hole 11 is provided on the shovel handle 1 above the limit slot. The shovel handle 1 is installed on the forklift 8 by inserting a pin through the first limit hole 11 and the second limit hole 12.

[0025] As Figure 1 And Figure 5It can be seen that in this embodiment, a limit plate 10 is welded on the gantry 9, and the two side plates of the "U"-shaped limit plate 10 are close to the rear end of the shovel handle 1. In another embodiment, the gantry 9 and the limit plate 10 are provided with through holes 17 that cooperate with each other, and the limit plate 10 and the gantry 9 are fixed by screws 17. The fixation of the gantry 9 and the shovel handle 1 is achieved in this way. First, the two forks on the forklift 8 are inserted into the two fork grooves 6 of the fixing seat 5. At this time, the two side plates of the "U"-shaped limit plate 10 enter the limit groove at the rear end of the shovel handle 1, and the limit plate The corresponding first limiting holes 11 and second limiting holes 12 on the two side plates on 10 coincide with each other in the upper and lower positions, and the gantry 9 and the shovel handle 1 can be fixed by inserting the pin therein. During movement, the fork and the fork groove 6 are subjected to force at the same time, which can ensure the stability of the furnace cleaning shovel. In another embodiment, the upper side plate of the limiting plate 10 does not enter the limiting groove, the upper side plate is located on the upper side of the shovel handle 1, and the lower side plate enters the limiting groove. At this time, the first limiting holes 11 and the second limiting holes 12 on the upper and lower side plates coincide with each other in the upper and lower positions, and the gantry 9 and the shovel handle 1 can also be fixed by inserting the pin therein.

[0026] As an implementable embodiment, the shovel handle 1 is detachably connected to the first connecting plate 2. Specifically, a fixing groove 13 is provided at the front end of the shovel handle 1. A fixing block 14 matching the fixing groove 13 is fixed at one end of the first connecting plate 2 close to the shovel handle 1. The fixing groove 13 and the fixing block 14 are both provided with fixing holes 15 correspondingly. Bolts 16 are passed through the fixing holes 15 to fix the shovel handle 1 and the first connecting plate 2. In this embodiment, the first connecting plate 2, the second connecting plate 3, the push plate 4 and the fixing block 14 together form a shovel head. After a long period of use, the shovel head will have an unsatisfactory cleaning efficiency. At this time, it needs to be replaced. The replacement of the shovel head is achieved in the following way: first, the bolts 16 in each corresponding fixing hole 15 are unscrewed. At this time, the shovel head and the shovel handle 1 are in a free state. The fixing block 14 of the unused shovel head can be inserted into the fixing groove 13, and then the bolts 16 are inserted into the corresponding fixing holes 15 to achieve the replacement of the shovel head.

[0027] When in use, the forklift 8 will bring the front end of the shovel head of the furnace cleaning shovel installed on the gantry 9 into contact with the side wall of the rotary furnace. At this time, the position of the forklift 8 is fixed, and the gantry 9 moves up and down under the control of the forklift 8. The tip formed by the first connecting plate 2 and the second connecting plate 3 of the shovel head breaks off the thicker or more solid slag on the furnace wall during the up and down movement. Then, as the slag on the furnace wall is broken in this up and down stroke, the forklift 8 adjusts its horizontal position, and the furnace cleaning shovel continues to break the slag. After the slag on the side wall of the rotary furnace is removed, the forklift 8 controls the push plate 4 of the shovel head of the furnace cleaning shovel to stick to the lower side wall of the rotary furnace, and the forklift 8 reverses to take out the slag at the bottom of the rotary furnace.
