Technical Field

[0001] This utility model relates to the field of vacuum furnace technology, and in particular to a vacuum separator furnace feeding and slag removal device. Background Technology

[0002] A vacuum separation furnace is an industrial device that performs heating treatment in a vacuum environment. By removing oxygen and gas molecules, it prevents materials from oxidizing, decarburizing, or becoming contaminated. It is widely used in metal processing, semiconductor manufacturing, aerospace and other fields.

[0003] Before the vacuum separation furnace is loaded, the molten alloy is temporarily stored in the heating tank of the feeding device. Under the action of the metal solution pump in the heating tank, the molten alloy is transported to the push column, and finally the loading operation is achieved through the push column.

[0004] During the temporary storage of molten alloy in the heating tank, alloy residue is produced and floats on the surface of the molten alloy. It needs to be cleaned regularly. The current cleaning method is to clean it manually with a ladle. This method is inefficient, and the cleaning temperature is high, the cleaning environment is poor, and there are certain safety hazards. Utility Model Content

The first slag discharge docking module is fixed on the front side of the heating tank, and the second slag discharge docking module is fixed on the rear side of the heating tank.

[0010] As an improvement: the first slag discharge docking module includes a first slag discharge support frame, which is fixed on the front side of the heating tank. A first support frame is slidably limited inside the first slag discharge support frame. A first rotating motor is horizontally fixed inside the first support frame.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings.

[0015] Please refer to Figures 1-4 A vacuum separator furnace feeding and slag removal device includes a heating tank 1, a slag removal device at the bottom of the heating tank 1, a high-temperature metal solution pump 2 inside the heating tank 1, a conveying pipe 3 connected to the output end of the high-temperature metal solution pump 2, and a slag discharge device on the left side of the heating tank 1.

Several limiting rods 14 are fixed on the portal frame 8, and the limiting rods 14 are movably locked in the sliding support block 6.

[0016] In this embodiment, during cleaning, the piston rod of the hydraulic cylinder 7 moves downward, placing the slag-removing mesh trough 9 below the molten metal. After a period of time, it is lifted upward. Then, under the action of the adjusting cylinder 15, the slag-removing mesh trough 9 is moved above the slag discharge device. The slag-removing mesh trough 9 moves downward under the action of the hydraulic cylinder 7, allowing the first docking block 21 to be inserted into the first docking slot 12 and the second docking block 27 to be inserted into the second docking slot 13. Subsequently, under the action of the first slag discharge docking module and the second slag discharge docking module, the opening of the slag-removing mesh trough 9 is turned downward, and the retrieved alloy residue is placed into the external slag mold. During the next slag removal, the position of the slag-removing mesh trough 9 in the heating tank 1 can be adjusted by adjusting the adjusting cylinder 15. By repeating the above actions, the alloy residue in the heating tank 1 can be quickly cleaned.

[0017] In this embodiment, the hydraulic cylinder 7 is a high-temperature resistant hydraulic cylinder 7.

[0018] An adjusting cylinder 15 is horizontally installed on the right side of the slag removal support frame 4, and the piston rod of the adjusting cylinder 15 is fixedly connected to the sliding support block 6.

[0019] In this embodiment, several counterweights 16 are provided at the bottom of the slag removal mesh trough 9, which can make the opening of the slag removal mesh trough 9 face upward in the molten liquid when slag is removed.

[0020] The slag discharge device includes a first slag discharge docking module and a second slag discharge docking module symmetrically arranged with respect to the first slag discharge docking module. The first slag discharge docking module is fixed on the front side of the heating tank 1, and the second slag discharge docking module is fixed on the rear side of the heating tank 1.

[0021] The first slag discharge docking module includes a first slag discharge support frame 17, which is fixed on the front side of the heating tank 1. A first support frame 18 is slidably limited inside the first slag discharge support frame 17. A first rotating motor 19 is horizontally fixed inside the first support frame 18. A first connecting rod 2014 is fixed on the rotor of the first rotating motor 19. A first docking block 21 is fixed on the end of the first connecting rod 2014 away from the first rotating motor 19. The first docking block 21 can be inserted into the first docking groove 12. A first limiting cylinder 22 is horizontally provided on the first slag discharge support frame 17. The piston rod of the first limiting cylinder 22 is fixedly connected to the first support frame 18. The second slag discharge docking module includes a second slag discharge support frame 23, which is fixed on the rear side of the heating tank 1. A second support frame 24 is slidably limited inside the second slag discharge support frame 23. A second rotating motor 25 is horizontally fixed inside the second support frame 24. A second connecting rod 2614 is fixed on the rotor of the second rotating motor 25.

[0022] The first connecting rod 2014 is rotatably limited within the first sleeve 29, which is fixed to the rear side of the first slag discharge support frame 17. The second connecting rod 2614 is rotatably limited within the second sleeve 30, which is fixed to the front side of the second slag discharge support frame 23.

[0023] In this embodiment, the first docking block 21 can be inserted into the first docking groove 12 and the second docking block 27 can be inserted into the second docking groove 13 by the first limiting cylinder 22 and the second limiting cylinder 28 respectively. The rotation of the first rotating motor 19 and the second rotating motor 25 can make the opening of the slag removal screen 9 face downward, thereby discharging the alloy residue inside into the slag discharge receiving trough.

[0024] Working principle: When slag removal is required, the hydraulic cylinder 7 is activated to move downwards, immersing the slag removal screen 9 into the molten metal. After a period of time, the hydraulic cylinder 7 moves upwards, lifting the slag removal screen 9. At this time, alloy residue will be collected in the slag removal screen 9. During the slag removal process, the position of the slag removal screen 9 in the heating tank 1 can be adjusted by adjusting the cylinder 15 to collect residue from different locations.

[0025] After the slag removal net trough 9 is lifted, the adjusting cylinder 15 is activated to move the slag removal net trough 9 above the slag discharge device. The hydraulic cylinder 7 is then activated to move downwards, so that the first docking block 21 is aligned with the first docking groove 12 and the second docking block 27 is aligned with the second docking groove 13. The first limiting cylinder 22 and the second limiting cylinder 28 are then activated to insert the first docking block 21 into the first docking groove 12 and the second docking block 27 into the second docking groove 13, respectively.

[0026] When the first rotating motor 19 and the second rotating motor 25 are turned on and rotated synchronously, the opening of the slag removal screen 9 faces downward under the rotation of the first rotating motor 19 and the second rotating motor 25, and the alloy residue inside can be placed into the external slag mold. One slag removal action is then completed.

[0027] After the slag removal is completed, the alloy molten liquid in the heating tank 1 can be injected into the push column through the conveying pipe 3 by the high temperature metal solution pump 2.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications should be covered within the scope of the technical solution claimed by this utility model.
