[0002] In the design of the conveying system in the metallurgical industry, the chute plays a role in connecting different process equipment and conveying and distributing materials, enabling various metals to run along the routes specified in the process flow during the conveying process, thereby ensuring the normal operation of production. Therefore, the chute plays a crucial role in the transfer of materials.

[0003] During the transfer process of aluminum alloy liquid, it is necessary to use a plugging device to control the opening and closing state between the chute and the discharge port of the melting furnace according to the state of the solution in the melting furnace. However, the existing plugging devices are not convenient for manual operation, are prone to leakage, and do not have an alarm function after the solution leaks into the chute. Content of the Utility Model

A pair of mounting plates are arranged on the melting furnace, and a support rod is rotatably fitted on the pair of mounting plates. A counterweight is arranged at one end of the support rod;

[0006] A first connecting rod is arranged on the side wall of the support rod. A hinge seat is fixedly connected to the first connecting rod. A push rod is hinged to the hinge seat. One end of the push rod is detachably connected with a plugging head, and the plugging head is inserted into the liquid discharge hood;

[0007] A temperature sensor is arranged on the inner side wall of the transfer chute close to the plugging head. The temperature sensor is electrically connected to an alarm through a wire.

[0009] Optionally, the second connecting rod is perpendicular to the support rod.

[0010] Optionally, a joint is fixedly connected to the side wall of the second connecting rod. The joint is detachably connected with a steel wire cable, and the steel wire cable is fixedly connected to the melting furnace.

[0011] Optionally, one end of the push rod is fixedly connected with a plug, an insertion socket is formed on the plugging head, and the plug is inserted into the insertion socket.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Referring to Figures 1 - 3 , the present invention provides a plugging device for an aluminum liquid transfer chute with an alarm function, including a melting furnace 1, a liquid discharge hood 2 connected to the outlet of the melting furnace 1, and a transfer chute 3 sleeved outside the liquid discharge hood 2. A pair of mounting plates 4 are arranged on the melting furnace 1, and a support rod 5 is rotatably fitted on the pair of mounting plates 4. A counterweight is arranged at one end of the support rod 5;

[0026] A first connecting rod 6 is arranged on the side wall of the support rod 5. A hinge seat 7 is fixedly connected to the first connecting rod 6. A push rod 8 is hinged to the hinge seat 7. One end of the push rod 8 is detachably connected to a plugging head 9, and the plugging head 9 is inserted into the liquid discharge hood 2;

[0027] A temperature sensor 10 is arranged on the inner side wall of the transfer chute 3 close to the plugging head 9. The temperature sensor 10 is electrically connected to an alarm 11 through a wire.

[0028] By rotating the support rod 5, the push rod 8 is driven by the first connecting rod 6 to insert the plugging head 9 into the liquid discharge hood 2. Since there is a counterweight on the support rod 5, the state of the support rod 5 is limited by the gravity of the counterweight, so that the plugging head 9 is stably blocked in the liquid discharge hood 2. And only by rotating the support rod 5 can the opening and closing state between the melting furnace 1 and the transfer chute 3 be quickly switched, with convenient operation and good plugging effect, effectively avoiding solution leakage.

[0029] By arranging a temperature sensor 10 on the inner side wall of the transfer chute 3 close to the plugging head 9, when the solution leaks into the transfer chute 3, the temperature sensor 10 can immediately sense the temperature change in the transfer chute 3, and the alarm 11 gives an alarm.

[0030] In a further optimized solution, the counterweight includes a second connecting rod 12. One end of the second connecting rod 12 is fixedly connected to the support rod 5, and the other end is fixedly connected to a counterweight block 13. The second connecting rod 12 is perpendicular to the support rod 5.

[0031] The state of the support rod 5 is restricted by the pressure generated by the counterweight block 13 on the end of the second connecting rod 12.

[0032] For a further optimized solution, a joint 14 is fixedly connected to the side wall of the second connecting rod 12. The joint 14 is detachably connected to a wire cable 15, and the wire cable 15 is fixedly connected to the melting furnace 1.

[0033] By connecting the wire cable 15 to the joint 14, the locking state of the support rod 5 can be further improved, and the plugging effect can be enhanced.

[0034] For a further optimized solution, a plug 16 is fixedly connected to one end of the push rod 8, and a socket 17 is formed on the plugging head 9. The plug 16 is inserted into the socket 17.

[0035] By providing the cooperation between the plug 16 and the socket 17 on the plugging head 9, it is convenient to replace the plugging head 9.

[0036] For a further optimized solution, both the liquid discharge cover 2 and the plugging head 9 are conical, which is convenient for the plugging head 9 to be inserted into the liquid discharge cover 2.

[0037] For a further optimized solution, openings are respectively formed on a pair of mounting plates 4. The support rod 5 passes through the pair of openings and is rotationally matched with the pair of openings.

[0038] For a further optimized solution, the liquid discharge cover 2 is close to the bottom surface of the pouring chute 3. The plugging head 9 abuts against the bottom surface of the pouring chute 3, and the axes of the liquid discharge cover 2 and the plugging head 9 are parallel. Thus, when the first connecting rod 6 rotates, since the push rod 8 is connected to the first connecting rod 6 through the hinge seat 7, and the plugging head 9 abuts against the bottom surface of the pouring chute 3, and through the conical cooperation between the liquid discharge cover 2 and the plugging head 9, the plugging head 9 can be gradually inserted into the liquid discharge cover 2, and the plugging head 9 is pressed against the liquid discharge cover 2 by the counterweight 13.

[0039] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present invention.

[0040] The above-described embodiments are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention should all fall within the protection scope determined by the claims of the present invention.
