[0002] An electric furnace is an industrial device that uses electrical energy to convert into heat energy for heating or melting. It is widely used in metal smelting, glass manufacturing, ceramic sintering, and laboratory heating. Its core function is to efficiently convert electrical energy into high temperatures through resistance heating, electric arc heating, or induction heating.

[0003] In the prior art, patent announcement number CN222364386U discloses a multi-temperature zone tubular furnace, including a furnace body, the furnace body including a heating tube and a pull rod partially extending into the heating tube; a drive assembly, disposed on one side of the furnace body, the drive assembly including a first bracket, a support plate and a power component disposed on the first bracket, the power component being disposed on the side of the support plate, the drive end of the power component being connected to the pull rod, and the power component driving the pull rod to move along the central axis of the heating tube.

[0004] The aforementioned device uses a lever to move the storage dish back and forth, allowing it to move in and out of the heating tube. In actual use, while the dish is being heated inside the tube, the lever is also heated to a very high temperature. When workers need to remove the dish, the high temperature of the lever makes them easily come into direct contact with these heat sources, increasing the risk of burns. Utility Model Content

[0005] The purpose of this invention is to provide an electric furnace with multi-stage gradient heating to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric furnace with multi-segment gradient heating, comprising a shell, a heating tube fixedly installed inside the shell, a plug fixedly installed at one end of the heating tube, a pull rod movably installed on the plug, a storage dish fixedly installed at the end of the pull rod, a limit block slidably installed on the pull rod, a cooling mechanism fixedly installed on the surface of the plug, the cooling mechanism comprising a water storage shell fixedly installed on the plug, a rotating cylinder rotatably installed inside the water storage shell, a water intake groove opened on the inner side of the rotating cylinder, a water receiving groove fixedly installed inside the water storage shell, a water leakage hole opened at the bottom of the water receiving groove, and a driving mechanism fixedly installed at the upper end of the water storage shell.

[0007] Preferably, the cooling mechanism further includes a helical gear ring fixedly installed on one side of the rotating drum, a helical gear rotatably installed on one side of the helical gear ring, and a screw threaded onto the plug.

[0008] Preferably, the water storage shell is provided with a rotating slip ring, and the rotating cylinder is rotatably installed in the water storage shell through the rotating slip ring.

[0009] Preferably, both the plug and the water storage shell are provided with square holes, the pull rod passes through the square holes in sequence through the water storage shell and the plug, and the limiting block is restricted to the plug by a screw.

[0010] Preferably, the drive mechanism includes an air inlet fixedly installed on the upper end of the water storage shell, a frame and a retainer fixedly installed inside the air inlet, a motor fixedly installed on the frame, a drive shaft fixedly installed at the output end of the motor, and the lower end of the drive shaft fixedly installed on a helical gear, a protective net fixedly installed at the upper end of the air inlet, and a fan blade fixedly installed on the drive shaft.

[0011] Preferably, the output end of the motor is provided with a coupling, and the drive shaft is fixedly installed at the output end of the motor through the coupling.

[0012] Preferably, the motor is fixedly mounted in the air inlet by a frame, the drive shaft is rotatably mounted in the air inlet by a retainer, the helical gear is rotatably mounted on one side of the helical gear ring by the drive shaft, and the helical gear meshes with the helical gear ring, and the fan blade is rotatably mounted in the air inlet by the drive shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this application, after the motor starts, it drives the helical gear to rotate, which in turn drives the helical gear ring to rotate. The rotation of the helical gear ring causes the rotating drum to rotate, and the movement of the rotating drum causes the water intake tank to circulate within the water storage shell. This process enables the cooling water at the bottom of the water storage shell to be transported to the water intake tank. The cooling water flows out through the drain hole, forming a water curtain. When the pull rod is pulled out, it passes through the water curtain, thereby cooling the hot pull rod and effectively avoiding the risk of burns to the operator during operation.

[0014] In this application, during motor startup, the drive shaft rotates, which in turn drives the fan blades to rotate. The rotation of the fan blades disturbs the surrounding air, causing air to flow into the water storage shell and exit from the front end of the shell. This process helps to remove heat from the cooling water, achieving the recycling of the cooling water. Attached Figure Description

[0017] 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.

[0018] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for an electric furnace with multi-stage gradient heating, including a shell 1, a heating tube 4 fixedly installed inside the shell 1, a plug 2 fixedly installed at one end of the heating tube 4, a pull rod 3 movably installed on the plug 2, a storage dish 301 fixedly installed at the end of the pull rod 3, a limit block 302 slidably installed on the pull rod 3, a cooling mechanism 5 fixedly installed on the surface of the plug 2, and a driving mechanism 6 fixedly installed at the upper end of the water storage shell 501. Through the cooperation of the cooling mechanism 5 and the driving mechanism 6, the pulled-out pull rod 3 can be cooled down to reduce the occurrence of scalding accidents.

[0019] like Figure 2 , Figure 3 and Figure 4 As shown, the cooling mechanism 5 includes a water storage shell 501 fixedly installed on the plug 2, a rotating cylinder 502 rotatably installed inside the water storage shell 501, a water intake groove 505 opened on the inner side of the rotating cylinder 502, a water receiving groove 503 fixedly installed inside the water storage shell 501, a water leakage hole 506 opened at the bottom of the water receiving groove 503, the cooling mechanism 5 also includes a helical tooth ring 504 fixedly installed on one side of the rotating cylinder 502, a helical gear 507 rotatably installed on one side of the helical tooth ring 504, a screw 201 threadedly installed on the plug 2, a rotating slip ring provided inside the water storage shell 501, and the rotating cylinder 502 rotatably installed inside the water storage shell 501 through the rotating slip ring.

[0020] Specifically, after starting the motor 603, it drives the helical gear 507 to rotate. As the helical gear 507 rotates, it further causes the helical gear ring 504 to rotate. The rotation of the helical gear ring 504 causes the rotating drum 502 to rotate, and once the drum 502 starts rotating, it drives the water inlet 505 to circulate within the water storage shell 501. This circulating motion effectively transports the cooling water at the bottom of the water storage shell 501 to the water receiving tank 503. After the cooling water is transported to the water receiving tank 503, it flows out through the drain hole 506, forming a continuous water curtain. When the pull rod 3 needs to be pulled out, it can pass through this water curtain, allowing the water flow to effectively cool the hot pull rod 3. In this way, it prevents the pull rod 3 from burning workers due to excessive temperature when it is removed, ensuring operational safety.

[0021] like Figure 2 , Figure 3 and Figure 5 As shown, the drive mechanism 6 includes an air inlet 601 fixedly installed on the upper end of the water storage shell 501. A frame 604 and a retainer 606 are fixedly installed inside the air inlet 601. A motor 603 is fixedly installed on the frame 604. A drive shaft 607 is fixedly installed at the output end of the motor 603, and the lower end of the drive shaft 607 is fixedly installed on the helical gear 507. A protective net 602 is fixedly installed at the upper end of the air inlet 601. A fan blade 605 is fixedly installed on the drive shaft 607. A coupling is provided at the output end of the motor 603, and the drive shaft 607 is fixedly installed at the output end of the motor 603 through the coupling.

[0022] Specifically, when the motor 603 starts operating, it causes the drive shaft 607 to rotate. As the drive shaft 607 rotates, it further causes the fan blades 605 to begin rotating. The rotation of the fan blades 605 agitates the surrounding air, drawing it in and into the interior space of the water storage housing 501. This agitated air is then discharged from the front end of the water storage housing 501. In this process, the airflow carries away heat from the cooling water, helping to maintain the cooling water within a suitable temperature range and ensuring its continuous circulation to maintain the system's cooling efficiency.

[0023] Working principle: The storage dish 301 can be fed into the heating tube 4 for heating by pulling rod 3. After the heating is completed, the pull rod 3 can be pulled out. When the pull rod 3 is pulled out, the motor 603 can be started. After the motor 603 is started, it will drive the helical gear 507 to rotate. After the helical gear 507 rotates, it will drive the helical gear ring 504 to rotate. After the helical gear ring 504 rotates, it will drive the rotating drum 502 to rotate. After the rotating drum 502 rotates, it will drive the water tank 505 to circulate in the water storage shell 501, thereby transporting the cooling water at the bottom of the water storage shell 501 to the water receiving tank 503. The cooling water transported to the water receiving tank 503 will leak out through the water leakage hole 506, thus forming a water curtain. When the pull rod 3 is pulled out, it will pass through the water curtain, thereby cooling the high temperature of the pull rod 3 and preventing burns to the staff when it is taken out. When the motor 603 starts, it drives the drive shaft 607 to rotate. The rotation of the drive shaft 607, in turn, drives the fan blades 605 to rotate. The rotation of the fan blades 605 disturbs outside air, drawing it into the water storage shell 501 and expelling it from the front end of the shell. This carries away the heat from the cooling water, allowing it to be recycled. After the pull rod 3 has finished cooling, the screw 201 can be loosened, allowing the storage dish 301 to be pulled out.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
