[0026] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.
[0027] like Figure 1 and 2 , a dust removal and slag cleaning integrated system, including a main body with a semi-enclosed structure and a fence.
[0028] Specifically, the body includes a frame, which is composed of four groups of columns 1 and four groups of cross beams 4. The side surfaces (left-right direction) of the frame are provided with side baffles 2, and the ends (front-back direction) are provided with end baffles 3 for blocking dust.
[0029] A slag cleaning device 5 is installed in the body. In this embodiment, the slag cleaning device 5 includes a second guide rail 5-3 arranged on the top of the frame, a moving device 5-2 moving along the second guide rail 5-3, a lifting mechanism 5-1 installed on the moving device 5-2, and a slag cleaning actuator 5-4 installed at the lower end of the lifting mechanism 5-1. The slag cleaning actuator 5-4 can be translated and lifted, and perform slag cleaning operations on the metal water ladle 10 located below, and clean the slag into the slag bucket 11 on the side. The metal water ladle 10 can be a tilting type or a fixed type.
[0030] Furthermore, a dust cover 6 is provided on the top of the frame to prevent dust from escaping from the top.
[0031] Furthermore, an inlet and outlet (inlet and outlet on one side, or one inlet and one outlet on both sides) are provided at the end of the body, and the metal water ladle 10 and the slag bucket 11 can pass through the inlet and outlet.
[0032] The main body is also provided with a pipeline interface 7 for connecting the dust removal pipeline. In this embodiment, the pipeline interface 7 is arranged on the side baffle 2. As other optional embodiments, the pipeline interface 7 can also be arranged on the end baffle 3 or the dust cover 6.
[0033] The body may be fixedly arranged relative to the ground. In this case, the dust removal pipeline comprises a first dust removal pipeline 14 whose inlet end is fixedly connected to the pipeline interface 7 .
[0034] Furthermore, the dust removal pipeline also includes a dust removal main pipeline 13 connected to the outlet end of the first dust removal pipeline 14 .
[0035] like Figure 3The slag cleaning system 100 can be arranged beside the electric furnace 200. The electric furnace 200 is connected to the main dust removal pipeline 13 through the second dust removal pipeline 12. The metal water ladle 10 and the slag bucket 11 matched with the electric furnace 200 are installed on the walking device 9 and move along the first guide rail 8. When cleaning slag, the walking device 9 walks along the first guide rail 8 to move the metal water ladle 10 and the slag bucket 11 to the bottom of the body, and then the slag cleaning device 5 performs slag scooping or slag scraping operations. After the operation is completed, the walking device 9 moves the metal water ladle 10 and the slag bucket 11 out of the body, moves to the next station or returns to the original station.
[0036] like Figure 4 The slag cleaning system 100 can also be arranged on both sides of the refining furnace 300, and the refining furnace 300 is connected to the dust removal main pipeline 13 through the third dust removal pipeline 15. As above, the metal water ladle 10 and the slag bucket 11 matched with the refining furnace 300 are installed on the walking device 9, which can move along the first guide rail 8 and cooperate with the slag cleaning system 100 to complete the slag cleaning operation.
[0037] like Figure 5 For the conventional arrangement of multiple refining furnaces 300 arranged side by side, the slag cleaning system 100 can be arranged on the molten steel transportation line between adjacent refining furnaces 300, and the slag cleaning system 100 between the refining furnaces 300 can be shared.
[0038] Furthermore, the body may also be movable relative to the ground.
[0039] like Figure 6 , the figure and Figure 5 Similarly, there are still multiple refining furnaces 300 arranged side by side, the metal water ladle 10 and the slag bucket 11 on both sides are fixedly arranged, and the slag cleaning system 100 located between the two refining furnaces 300 can move along the third guide rail 16. In this case, each working position of the slag cleaning system 100 needs to be provided with a first dust removal pipeline 14, and the inlet end of the first dust removal pipeline 14 should be docked with the pipeline interface 7 but not connected. When the slag cleaning system 100 moves to a certain working position, the first dust removal pipeline 14 at this position corresponds to the position of the pipeline interface 7, the distance is relatively close but not hard connected (or soft contact sealing is achieved through a flexible rubber ring or other device), and the dust inside the body is adsorbed into the dust removal main pipeline 13 through negative pressure.
[0040] Figure 3 to Figure 4 In the scenario shown, if the metal water ladle 10 and the slag bucket 11 are immovable, the same Figure 6 This is implemented using a mobile body, which will not be described in detail here.
[0041] The movement of the main body is not limited to rail-type or wheel-type, and can also be moved by means of a crane or the like.
[0042] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
