Description

Technical Field

[0001] This utility model relates to the field of crucible furnace technology, and in particular to a rotary crucible furnace structure. Background Technology

[0002] A crucible furnace is the simplest type of smelting equipment, mainly used for melting non-ferrous metals with relatively low melting points, such as copper, aluminum, and their alloys. In this type of furnace, the alloy is melted inside the crucible, and the heat is transferred to the furnace charge through the crucible. The furnace charge and combustion products do not come into direct contact, so the chemical composition of the alloy is almost unaffected by the furnace atmosphere, and the temperature of the molten alloy is relatively uniform.

[0003] In the prior art, when draining the molten metal from the crucible furnace, it is necessary for the staff to manually drain it. According to the contents of the Chinese utility model patent CN215766440U, which describes an electrically heated crucible furnace, although the crucible furnace can be tilted slightly, most of the molten metal remains inside the crucible furnace, so the staff needs to manually drain the molten metal. However, manual draining poses certain safety hazards.

[0004] To address the aforementioned technical deficiencies, a solution is proposed that can automatically discharge the molten metal from the crucible furnace without requiring manual discharge by staff, thereby improving safety during the discharge of molten metal. Utility Model Content

[0005] The purpose of this invention is to provide a rotary crucible furnace structure to solve the problems mentioned above.

[0006] The objective of this utility model can be achieved through the following technical solution: a rotary crucible furnace structure, including a base plate, two side plates fixedly connected to the top of the base plate, two arc-shaped grooves opened on the side walls of the two side plates, a U-shaped plate fixedly connected to the side walls of the two side plates, a first motor fixedly connected to the side walls of the two U-shaped plates, a rotating rod fixedly connected to the extended ends of the two first motors, and the two rotating rods respectively pass through the two side plates and are rotatably connected to the side plates through bearings; An outer cylinder is fixedly connected between the two rotating rods. The outer cylinder is rotatably connected between two side plates. Two drive rods are fixedly connected to both sides of the outer cylinder. The four drive rods pass through and are movably connected in four arc-shaped grooves. Connecting rods are fixedly connected to both sides of the two rotating rods. One end of each of the four connecting rods is fixedly connected to the side wall of the four drive rods. The bottom of the outer cylinder is provided with a rotating structure, and the outer cylinder is connected to the crucible furnace body through the rotating structure. The crucible furnace body is rotatably connected inside the outer cylinder, and the top of the crucible furnace body is provided with a lid.

[0007] Preferably, the top of the base plate has a placement groove, in which a collection box is placed, and handles are fixedly connected to both sides of the collection box.

[0008] Preferably, L-shaped slots are provided on both sides of the placement slot, and a locking rod is fixedly connected to both sides of the collection box, with the two locking rods respectively movably connected in the two L-shaped slots.

[0009] Preferably, the outer cylinder is made of heat-insulating material.

[0010] Preferably, the rotating structure includes a second motor, which is fixedly connected to the bottom of the outer cylinder by a fixing plate. A fixing rod is fixedly connected to one end of the output shaft of the second motor. The fixing rod passes through the bottom of the outer cylinder and is rotatably connected to the outer cylinder through a bearing. The top of the fixing rod is fixedly connected to the bottom side wall of the crucible furnace body.

[0011] Preferably, a thrust bearing is rotatably connected to the bottom of the crucible furnace body, and the bottom of the thrust bearing is rotatably connected to the bottom side wall of the outer cylinder, with the fixing rod located in the inner ring of the thrust bearing.

[0012] The beneficial effects of this utility model are: (1) By starting two first motors, four drive rods and two rotating rods are driven to rotate simultaneously. The two rotating rods can exert force in the middle of the outer cylinder to drive the outer cylinder to rotate, while the four drive rods can exert force at the upper and lower ends of the outer cylinder to drive the outer cylinder to rotate. Thus, the upper, middle and lower ends of the outer cylinder can be driven to rotate simultaneously, improving the stability of the outer cylinder when rotating. This allows the outer cylinder to drive the crucible furnace body to rotate, discharging the molten metal in the crucible furnace body into the collection box. There is no need for workers to manually discharge the molten metal in the crucible furnace body. Compared with the traditional method of workers taking out the liquid from the crucible furnace body, this utility model can automatically discharge the liquid from the crucible furnace body, improving the safety when discharging the molten metal. (2) When the crucible furnace body melts the metal material, the second motor is started. The output shaft of the second motor drives the fixed rod to rotate, and the fixed rod drives the crucible furnace body to rotate. The crucible furnace body rotates on the surface of the thrust bearing. During the rotation of the crucible furnace body, the heat inside the crucible furnace body can be transferred to the metal material more evenly, so that the material is heated evenly in all parts, effectively avoiding quality problems caused by uneven heating, improving the performance and consistency of the product. At the same time, the rotation of the crucible furnace body itself plays a stirring role, eliminating the need for an additional stirring device, simplifying the equipment structure and reducing costs.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: The application background of this utility model is based on a rotary crucible furnace structure, and the molten metal in the crucible furnace needs to be transferred manually. The technical solution of this utility model is to solve the problem of how to automatically discharge the molten metal in the crucible furnace and reduce the safety hazards in the process of transferring molten metal. Please see Figure 1-4 As shown, this embodiment is a rotary crucible furnace structure, including a base plate 1, two side plates 13 fixedly connected to the top of the base plate 1, two arc-shaped grooves 4 opened on the side walls of the two side plates 13, U-shaped plates 11 fixedly connected to the side walls of the two side plates 13, first motors 5 fixedly connected to the side walls of the two U-shaped plates 11, and rotating rods 15 fixedly connected to the extended ends of the two first motors 5. The two rotating rods 15 pass through the two side plates 13 respectively and are rotatably connected to the side plates 13 through bearings. An outer cylinder 12 is fixedly connected between two rotating rods 15. The outer cylinder 12 is rotatably connected between two side plates 13. Two drive rods 7 are fixedly connected to both sides of the outer cylinder 12. The four drive rods 7 pass through and are movably connected in four arc-shaped grooves 4. Connecting rods 6 are fixedly connected to both sides of the two rotating rods 15. One end of the four connecting rods 6 is fixedly connected to the side wall of the four drive rods 7. The bottom of the outer cylinder 12 is provided with a rotating structure, and the outer cylinder 12 is connected to the crucible furnace body 8 through the rotating structure. The crucible furnace body 8 is rotatably connected inside the outer cylinder 12, and the top of the crucible furnace body 8 is provided with a lid 9.

[0017] The top of the base plate 1 has a placement groove 19, and a collection box 14 is placed in the placement groove 19. Both sides of the collection box 14 are fixedly connected to handles 2.

[0018] Both sides of the placement slot 19 are provided with L-shaped slots 3, and both sides of the collection box 14 are fixedly connected with locking rods 10. The two locking rods 10 are respectively movably connected in the two L-shaped slots 3. The outer cylinder 12 is made of heat-insulating material.

[0019] Reference Figure 1-4 As shown, during use, by opening the lid 9, the metal material to be melted is poured into the crucible furnace body 8. The crucible furnace body 8 melts the metal material, and at the same time, the rotating structure is activated to drive the crucible furnace body 8 to rotate, so that the crucible furnace body 8 rotates inside the outer cylinder 12, improving the melting efficiency of the metal material inside the crucible furnace body 8. When it is necessary to discharge the material inside the crucible furnace body 8, the two first motors 5 are activated. The two first motors 5 drive the two rotating rods 15 to rotate. The two rotating rods 15 simultaneously drive the outer cylinder 12 to rotate. When the two rotating rods 15 rotate, they can simultaneously drive the four connecting rods 6 and the four driving rods 7 to rotate. The four driving rods 7 simultaneously drive the outer cylinder 12 to rotate, so that the upper, middle and lower ends of the outer cylinder 12 can be driven to rotate at the same time, improving the stability of the outer cylinder 12 when rotating. The outer cylinder 12 drives the crucible furnace body 8 to rotate, so that the crucible furnace body 8 tilts, thereby discharging the molten metal inside the crucible furnace body 8 into the collection box 14. With the two locking rods 10 in place, when the collection box 14 is placed into the placement slot 19, the two locking rods 10 enter the two L-shaped locking slots 3. By turning the handle 2, the collection box 14 is rotated, and the collection box 14 drives the two locking rods 10 to rotate, so that the two locking rods 10 enter the two L-shaped locking slots 3. This can limit the position of the collection box 14, improve the stability of the collection box 14, and prevent the impact force generated when the molten metal enters the collection box 14 from causing the collection box 14 to tip over. As can be seen from the above operation process, by starting the two first motors 5, the four drive rods 7 and the two rotating rods 15 can rotate simultaneously. The two rotating rods 15 can exert force in the middle of the outer cylinder 12 to drive the outer cylinder 12 to rotate, while the four drive rods 7 can exert force at the upper and lower ends of the outer cylinder 12 to drive the outer cylinder 12 to rotate. Thus, the upper, middle and lower ends of the outer cylinder 12 can be driven to rotate simultaneously, which improves the stability of the outer cylinder 12 when rotating. This allows the outer cylinder 12 to drive the crucible furnace body 8 to rotate, and discharges the molten metal in the crucible furnace body 8 into the collection box 14. There is no need for the staff to manually discharge the molten metal in the crucible furnace body 8, which improves the safety of molten metal discharge. Example 2: Please refer to Figure 3As shown, the rotating structure includes a second motor 17, which is fixedly connected to the bottom of the outer cylinder 12 via a fixing plate. One end of the output shaft of the second motor 17 is fixedly connected to a fixing rod 18, which passes through the bottom of the outer cylinder 12 and is rotatably connected to the outer cylinder 12 via a bearing. The top of the fixing rod 18 is fixedly connected to the bottom side wall of the crucible furnace body 8.

[0020] A thrust bearing 16 is rotatably connected to the bottom of the crucible furnace body 8. The bottom of the thrust bearing 16 is rotatably connected to the inner bottom side wall of the outer cylinder 12, and the fixing rod 18 is located in the inner ring of the thrust bearing 16.

[0021] When the crucible furnace body 8 is melting metal materials, the second motor 17 is started. The output shaft of the second motor 17 drives the fixed rod 18 to rotate, and the fixed rod 18 drives the crucible furnace body 8 to rotate. The crucible furnace body 8 rotates on the surface of the thrust bearing 16. During the rotation of the crucible furnace body 8, the heat inside the crucible furnace body 8 can be transferred to the metal materials more evenly, so that all parts of the material are heated evenly. This effectively avoids quality problems caused by uneven heating, improves the performance and consistency of the product, and at the same time, the rotation of the crucible furnace body 8 itself plays a stirring role, eliminating the need for an additional stirring device, simplifying the equipment structure and reducing costs.

[0022] Combining Embodiments 1 and 2, it can be seen that, on the one hand, by starting the two first motors 5, four drive rods 7 and two rotating rods 15 are driven to rotate simultaneously. The two rotating rods 15 can exert force in the middle of the outer cylinder 12, driving the outer cylinder 12 to rotate, while the four drive rods 7 can simultaneously exert force at the upper and lower ends of the outer cylinder 12, driving the outer cylinder 12 to rotate. This allows the upper, middle, and lower ends of the outer cylinder 12 to be driven to rotate simultaneously, improving the stability of the outer cylinder 12 during rotation. This causes the outer cylinder 12 to drive the crucible furnace body 8 to rotate, discharging the molten metal inside the crucible furnace body 8 into the collection box 14. This eliminates the need for manual removal of molten metal from the crucible furnace body 8, improving safety during molten metal removal. Furthermore, starting the second motor 17 drives the crucible furnace body 8 to rotate. During this rotation, heat is transferred more evenly to the metal material, ensuring consistent heating across all parts of the material. This effectively avoids quality problems caused by uneven heating, improving product performance and consistency. Simultaneously, the rotation of the crucible furnace body 8 itself acts as a stirrer, eliminating the need for additional stirring devices, simplifying the equipment structure, and reducing costs.

[0023] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
