Technical Field

[0001] The utility model relates to the field of slag channels, and specifically refers to a slag channel for long-distance transportation of high-temperature slag. Background Art

[0002] During the steelmaking process, in addition to producing steel products, there will also be some slag that is not molten steel. These slags can be applied to the construction field, fertilizer field, brick and tile field, etc. through post-treatment. For example, in the construction field, it can be used for road paving, making cement, wall tiles, floor tiles and other building materials. It has high strength, good toughness, strong waterproofness, is not easy to age, and is not easy to crack, and is a building material with good market prospects. Therefore, in the production of steel mills, a slag channel for long-distance transportation of high-temperature slag is used to transport the slag.

[0003] The existing slag channel for long-distance transportation of high-temperature slag pours the slag into the slag channel through a slag dumping device. The slag in the slag channel flows to the water outlet of the slag channel and is then transported to the cooling area for cooling by a transportation device under the slag channel.

[0004] Although the existing slag channel for long-distance transportation of high-temperature slag can transport the slag over a long distance, due to the load limit of the transportation device, when a large amount of slag is transported over a long distance, multiple round trips are required. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that the transportation device of the existing slag channel needs to make multiple round trips during large-scale transportation.

[0006] To solve the above technical problem, the technical solution provided by the utility model is: a slag channel for long-distance transportation of high-temperature slag, including a slag dumping device. A slag channel is provided below the slag dumping device. A flow control tank, a water quenching tank, and a transportation tank are successively arranged at the flow outlet of the slag channel. Explosion-proof tank covers are arranged above the flow control tank, the water quenching tank, and the transportation tank. High-pressure flushing devices are arranged at both ends of the inlet of the water quenching tank and inside the explosion-proof tank cover.

[0007] As an improvement, the slag dumping device includes a slag tank, slag tank supports located around the slag tank, and a cable device for adjusting the dumping angle of the slag tank. The connecting rod of the slag tank support is rotationally connected to the connecting column of the slag tank through body contact.

[0008] As an improvement, a dumping support is arranged at the bottom of the slag tank. The cable device includes a cable reel connected to the dumping support and an adjustment motor for adjusting the length of the cable of the cable reel. The cable reel and the adjustment motor are both fixedly connected to the slag tank support through screws. The cable head end of the cable reel passes through the dumping support, and the dumping support is connected to the dumping support hole at the bottom of the slag tank through a pin.

[0009] As an improvement, an impact-proof slope is provided in the groove of the slag trench.

[0010] As an improvement, the high-pressure flushing device includes high-pressure nozzles located at both ends of the inlet of the water quenching tank and inside the explosion-proof tank cover, and a pressurizing pump device for supplying water. The high-pressure flushing device is connected to the pressurizing pump device through a high-pressure water pipe, and the high-pressure nozzles pass through the water quenching tank and the explosion-proof tank cover.

[0011] As an improvement, fixing frames are provided below the slag trench, the flow control trench, the water quenching tank, and the conveying trough.

[0012] The advantages of the present utility model compared with the prior art are as follows: Through the high-pressure flushing devices on the water quenching tank and the explosion-proof tank cover, the device uses water flow to disperse the slag. Through the high-pressure flushing device provided inside the explosion-proof tank cover on the conveying trough, the dispersed slag is continuously transported towards the target along with the water flow. Compared with the existing technology, the single transportation weight of this device is not limited, avoiding the situation where a large amount of slag needs to be transported back and forth multiple times.

[0020] The following further elaborates on the present utility model in conjunction with the accompanying drawings.

[0021] As shown in the attached Figure 1 description, a long-distance slag ditch for transporting high-temperature slag includes a slag pouring device 1. A slag ditch 2 is provided below the slag pouring device 1. A flow control trough 3, a water quenching trough 4, and a conveying trough 5 are successively arranged at the outflow port of the slag ditch. Explosion-proof trough covers 6 are provided above the flow control trough 3, the water quenching trough 4, and the conveying trough 5. High-pressure flushing devices 7 are provided at both ends of the inflow port of the water quenching trough 4 and inside the explosion-proof trough cover 6. Fixed frames 8 are provided below the slag ditch 2, the flow control trough 3, the water quenching trough 4, and the conveying trough 5. The slag flows out from the slag pouring device 1 and successively flows through the slag ditch 2, the flow control trough 3, the water quenching trough 4, and the conveying trough 5.

[0022] As shown in the attached Figure 1 、 2 、Figure 3, the slag pouring device 1 includes a slag tank 11, slag tank supports 12 surrounding the slag tank 11, and a cable device 13 for adjusting the tilting angle of the slag tank 11. The slag tank supports 12 and the slag tank 11 are rotationally connected by body contact. A tilting support 111 is provided at the bottom of the slag tank 11. The cable device 13 includes a cable reel 131 connected to the tilting support 111 and an adjusting motor 132 for adjusting the length of the rope of the cable reel 131. The cable reel 131 and the adjusting motor 132 are both fixedly connected to the slag tank supports 12 by screws. The rope end of the cable reel 131 passes through the tilting support 111. The tilting support 111 is connected to the tilting support hole at the bottom of the slag tank 11 by a pin. The speed of the slag flowing out is controlled by the cable device 13 to prevent the slag from overflowing in the slag ditch 2.

[0023] As shown in the attached Figure 1 、 5 、Figure 6, an impact-proof slope 21 is provided in the groove of the slag ditch 2. The high-pressure flushing device 7 includes high-pressure nozzles 71 located at both ends of the inflow port of the water quenching trough 4 and inside the explosion-proof trough cover 6 and a pressurizing pump device 72 for supplying water. The high-pressure flushing device 7 is connected to the pressurizing pump device 72 through a high-pressure water pipe. The high-pressure nozzles 71 pass through the water quenching trough 4 and the explosion-proof trough cover 6. The slag is dispersed by the high-pressure water column of the high-pressure nozzles 71. The dispersed slag flows in the water quenching trough 4 and the conveying trough 5 along with the water flow until it reaches the outlet end of the conveying trough 5.

[0024] In the specific implementation of the present utility model, the rope end of the rope reel 131 passes through the tipping bracket 111 and is fixedly connected. The rope reel 131 is fixed on the corresponding reel sleeve on the slag pot bracket 12. The adjusting motor 132 is fixed on the reel sleeve at one end of the rope reel 131 by screws. The output shaft of the adjusting motor 132 passes through the slag pot bracket 12 and is fixedly connected to the inner reel sleeve of the rope reel 131. Therefore, the rope reel 131 and the adjusting motor 132 rotate synchronously. Place the fixing frame 8 below the tipping opening of the slag pot 11, and place the slag ditch 2, the flow control groove 3, the water quenching groove 4, and the conveying groove 5 on the fixing frame 8 in sequence. The number of the fixing frames 8 below the conveying groove 5 is determined according to the transportation distance.

[0025] During use, the slag tipping device (1) is moved above the slag ditch 2 by a crane. The adjusting motor 132 is turned on to adjust the length of the rope of the rope reel 131. The slag pot 11 located between the slag pot brackets 12 will perform a rotational movement, causing the slag pot 11 to tilt at a certain angle to control the flow rate of the slag. The slag is tipped onto the impact-proof slope 21 in the trench of the slag ditch 2 to reduce the impact damage of the slag on the bottom surface of the slag ditch 2. The slag flows into the flow control groove 3 through the slag ditch 2, and through the flow control groove 3, it is ensured that the high-pressure flushing devices 7 at both ends of the water quenching groove 4 can completely disperse the slag to avoid blockage by large pieces of slag. While the adjusting motor 132 is turned on, the pressure pump device 72 is turned on, and the slag is continuously flushed towards the rear conveying groove 5 through the high-pressure flushing device 7 inside the explosion-proof tank cover 6. The slag-water mixture in the conveying groove 5 is also impacted by the slag water through the high-pressure flushing device 7 inside the explosion-proof tank cover 6 to ensure the flow of the slag water in the rear conveying groove 5 until the slag is completely transported.

[0026] The above describes the present utility model and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the creative concept of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
