Description

Technical Field

[0001] The utility model belongs to the technical field of slag cake pretreatment, and particularly relates to a slag cake pretreatment device for a belt conveyor. Background Art

[0002] Steel slag is a waste product produced during the steelmaking process. During the steelmaking process, impurities in raw materials such as iron ore react with added fluxes to form slag, which is then discharged from the furnace and cooled to become steel slag. The main components of steel slag include calcium, iron, silicon, magnesium, aluminum, and other elements, as well as small amounts of phosphorus and sulfur. Steel slag can be recycled through wet carbonization. The treated tailings are filtered and formed into a moist slag cake containing a certain amount of water.

[0003] Belt conveyors are currently used to transport the slag cake, but the cake is large and cake-shaped. Directly conveying the slag cake to the dryer or grinder via a conveyor can lead to problems such as difficulty in direct entry and blockage. Even if it does enter the dryer or grinder, this can affect handling efficiency, further impacting the cake's processing efficiency and causing unnecessary inconvenience for the user. Some processes incorporate a breaker or crusher before the slag cake enters the dryer, but this also increases the complexity of the process.

[0030] As shown in the utility model an embodiment of a kind of for belt conveyor's cake pretreatment device, including: conveying support table 1, loosening mechanism 2 and shearing mechanism 3. Figures 1-4

[0031] As shown in the utility model an embodiment of a kind of for belt conveyor's cake pretreatment device, including: conveying support table 1, loosening mechanism 2 and shearing mechanism 3. Figure 1 As shown in the utility model an embodiment of a kind of for belt conveyor's cake pretreatment device, including: conveying support table 1, loosening mechanism 2 and shearing mechanism 3.

[0032] Among them, the side of conveying belt 101 is installed with lower sliding plate 105, for guiding the movement of cake, so that cake falls in the designated position.

[0033] As shown in the utility model an embodiment of a kind of for belt conveyor's cake pretreatment device, including: conveying support table 1, loosening mechanism 2 and shearing mechanism 3. Figures 1-3 ​As shown, the loosening mechanism 2 is mounted on the conveying support table 1, and the loosening mechanism 2 comprises a fixing frame 201 for supporting the device and structure, and a lifting top rod 202 is arranged in the fixing frame 201 for supporting a support horizontal plate 203 and a loosening strip tooth 204 and moving the same. One end of the lifting top rod 202 is fixedly connected with the support horizontal plate 203 for supporting a plurality of loosening strip teeth 204 and moving a connecting column 306 and a fixing horizontal plate 307.

[0034] Specifically, the loosening strip tooth 204 is mounted on one side of the support horizontal plate 203 for piercing the slag cake so as to loosen the slag cake and facilitate subsequent shearing. A pair of guide inclined plates 205 are fixed on the fixing frame 201, one end of the guide inclined plate 205 is provided with an inclined edge for guiding the slag cake to move to the middle of the conveying belt 101 to facilitate the loosening of the loosening strip tooth 204 and the shearing of the shearing knife 302.

[0035] As shown in the figure, Figures 1-3 A pair of support guide frames 206 are mounted in the fixing frame 201 for providing space and track for the lifting movement of the first support sliding block 207. The first support sliding block 207 is slidingly arranged in the pair of support guide frames 206, and one end of the pair of first support sliding blocks 207 is fixedly connected with the lifting top rod 202 for supporting the lifting top rod 202 and moving the lifting top rod 202 upward to facilitate the downward movement of the lifting top rod 202 again.

[0036] Specifically, the first support sliding block 207 is fixedly connected with the first push spring 208 between the first support sliding block 207 and the support guide frame 206 for pushing the first support sliding block 207 to move the first support sliding block 207 upward to move the lifting top rod 202 upward.

[0037] As shown in the figure, Figure 3 The shearing motor 209 is mounted on the fixing frame 201 for rotating the transmission support shaft 210 to provide power for loosening and shearing the slag cake. The transmission support shaft 210 is mounted on the output end of the shearing motor 209 for supporting the three-pronged push block 212 and rotating the three-pronged push block 212. The fixed bearing 211 is fixedly connected between the end of the transmission support shaft 210 away from the shearing motor 209 and the fixing frame 201 for fixing the transmission support shaft 210 to prevent the transmission support shaft 210 from shaking and tilting and to prevent the rotation of the transmission support shaft 210 from being affected.

[0038] As shown in the figure, Figures 1-3 The three-pronged push block 212 is mounted on the transmission support shaft 210 and is arranged above the lifting top rod 202 for pushing the lifting top rod 202 to move the support horizontal plate 203 and the loosening strip tooth 204 downward to facilitate the loosening and shearing of the slag cake.

[0039] As Figures 1-4 shown, the shearing mechanism 3 is installed on one side of the fixed frame 201, and the shearing mechanism 3 includes a shielding frame 301 for shielding the slag cake so that the slag cake is not easy to fall off. A fixed horizontal plate 307 is arranged in the shielding frame 301 for supporting and driving the shearing knife 302 to move up and down. The shearing knife 302 is installed on the fixed horizontal plate 307 for shearing the slag cake. The shearing knife 302 is used for shearing the slag cake.

[0040] As Figures 1-4 shown, the second supporting sliding block 304 is fixedly connected with the shielding frame 301 and the second push spring 305 is fixedly connected between the second supporting sliding block 304 and the shielding frame 301 for pushing the second supporting sliding block 304, so that the second supporting sliding block 304 can drive the fixed horizontal plate 307 to rise. A plurality of connecting column rods 306 are fixedly connected between the supporting horizontal plate 203 and the fixed horizontal plate 307 for driving the fixed horizontal plate 307 to move.

[0041] In specific use, the slag cake is placed on the conveying belt 101, and then the slag cake is conveyed forward by the conveying belt 101. The transmission supporting shaft 210 and the triangular push block 212 are rotated by the shearing motor 209, and the rotation of the triangular push block 212 pushes the lifting jack 202, so that the lifting jack 202 drives the supporting horizontal plate 203 and the plurality of loosening strip teeth 204 to move downward, so that the loosening strip teeth 204 can be inserted into the slag cake to achieve the effect of loosening the slag cake.

[0042] After the lifting jack 202 descends, the triangular push block 212 no longer pushes the lifting jack 202. At this time, the first supporting sliding block 207 is pushed up by a pair of first push springs 208, so that the lifting jack 202 is lifted, and then the lifting jack 202 is pushed down by the triangular push block 212, so that the loosening strip teeth 204 are inserted into the slag cake in the conveying process.

[0043] When the supporting horizontal plate 203 descends, the fixed horizontal plate 307 is driven to move downward by the connecting column rod 306, so that the fixed horizontal plate 307 drives the shearing knife 302 to move downward to achieve the effect of shearing the slag cake. Then the slag cake can be conveyed into the crusher by the conveying belt 101, which is convenient for the crusher to process.

[0044] At the same time, the device can be modularly installed and disassembled, and can be flexibly combined and applied according to actual process processing requirements.
