Description

Technical Field

[0001] The invention relates to the technical field of metallurgical auxiliary slag cleaning devices, in particular to an automatic reciprocating chute slag cleaning device. Background Art

[0002] In the metal smelting industry, slag removal is one of the necessary process flows. Among them, the chute is a device frequently used in the production of the metallurgical industry. For example, when liquid blast furnace slag and steel slag are treated by air quenching, the chute plays the role of drainage, diversion, and flow control. The liquid slag flows through the chute and is guided and constrained by the chute to control the appropriate flow rate, flow rate, and position. The blowing device quenches the liquid slag into a finished product under the chute mouth. In this process, after the liquid slag is cooled at the chute mouth, its fluidity weakens, its viscosity increases, and it may even directly cool to a solid state, which will adhere to the chute mouth, thereby blocking and blocking the air quenching blowing port, so that the liquid slag cannot be effectively air quenched, affecting the continuity of the air quenching treatment. Summary of the invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figure 1 and Figure 2 As shown, the present invention provides an automatic reciprocating chute 4 slag cleaning device, which includes a slag cleaning rod assembly, a reciprocating motion system and a chute 4. The slag cleaning rod assembly includes a scraper plate 3, the scraper plate 3 is attached to the bottom of the chute 4, and the width of the scraper plate 3 is less than the thickness of the chute 4. The slag cleaning rod assembly is arranged at the output end of the reciprocating motion system, and the reciprocating motion system drives the slag cleaning rod assembly to perform reciprocating linear motion.

[0027] The technical solution of the present invention is to arrange the slag cleaning rod assembly at the output end of the reciprocating motion system so that the reciprocating motion system drives the slag cleaning rod assembly to perform reciprocating linear motion, that is, the scraper plate 3 fits the bottom of the chute 4 to perform reciprocating linear motion, thereby automatically and continuously cleaning the adhesive slag at the groove of the chute 4 without affecting the production continuity, wherein the width of the scraper plate 3 is slightly smaller than the thickness of the chute 4, which can ensure that the flow of liquid slag is not blocked.

[0028] Specifically, in the present embodiment, the chute 4 is made of cast steel, the thickness of the bottom panel of the chute 4 is 100 mm, and the width of the scraper plate 3 is slightly smaller than the thickness of the chute 4, which can clean the bonding slag at the slot of the chute 4 and allow the liquid slag to continue to flow to the bottom of the chute 4.

[0029] The slag cleaning rod assembly also includes a push rod 2. One end of the push rod 2 is connected to the output end of the reciprocating motion system. The other end of the push rod 2 is connected to the scraper plate 3. The push rod 2 is made of high temperature resistant material. The scraper plate 3 is made of high temperature resistant material. Specifically, in this embodiment, the push rod 2 and the scraper plate 3 are connected by welding. The push rod 2 and the scraper plate 3 are made of tungsten rods.

[0030] The reciprocating motion system includes a motor 1. The motor 1 is an automatic reciprocating telescopic motor, which can automatically, continuously, and reciprocatingly push and pull the slag cleaning rod assembly to move. The length of one stroke of the motor 1 is consistent with the slot width of the chute 4. Specifically, in this embodiment, the starting position of the scraper top is on the side of the slot of the chute 4 close to the motor 1, and the motor 1 ends at the other side of the slot of the chute 4 during the pushing stroke, and the length of one stroke is consistent with the slot width of the chute 4.

[0031] During the working process, the motor 1 pushes the push rod 2 and the scraper plate 3 from the initial position to the final position, completely removes the adhesive residue at the chute 4, and then returns to the initial position, and then keeps circulating to continuously clean the adhesive residue at the chute 4. The tail end of the scraper plate 3 is an oblique cut, which can improve the slag cleaning effect.
