Abstract
Description
Technical Field
[0001] This utility model relates to the field of smelting furnaces, and in particular to a molten metal discharge component for a smelting furnace. Background Technology
[0002] In the metal smelting process, the discharge stage of the smelting furnace is crucial. Traditional smelting furnaces typically use simple discharge valves to control the flow of molten metal. However, this method has many significant drawbacks and cannot meet the demands of modern, efficient, precise, and safe smelting production.
[0003] In existing technologies, during discharge, the valve is first opened, and molten metal flows out from the discharge port. However, the trajectory of the molten metal is not fixed but rather uncertain. As the volume of molten metal in the furnace changes, parameters such as the flow rate and internal pressure also change, leading to instability in the trajectory, including deviations and fluctuations. This uncertain trajectory poses a challenge to subsequent molten metal reception. Molten metal storage containers struggle to accurately receive the metal, easily causing splashing and spillage, resulting in waste, increased production costs, and potential threats to operator safety.
[0004] Furthermore, traditional discharge valves, being close to the high-temperature molten metal in the smelting furnace, are subjected to harsh, high-temperature operating environments for extended periods, often resulting in a short service life. Improving the valve's heat resistance typically requires the use of special, more heat-resistant materials, which significantly increases the production cost of the smelting furnace. Even with better heat-resistant materials, valves still inevitably experience wear and deformation during frequent high-temperature smelting discharge operations, affecting the accuracy and stability of discharge control and potentially leading to valve failure and production accidents. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a molten metal discharge assembly for a smelting furnace. This assembly has a simple structure and allows the molten metal to be guided through a flow channel when discharged from the smelting furnace, ensuring precise landing. Furthermore, it is more cost-effective and reliable when sealing the discharge hole.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a molten metal discharge assembly for a smelting furnace, comprising:
[0007] A flow channel is fixed at the end of the discharge port of the smelting furnace. The flow channel includes a bottom plate, side plates on both sides of the bottom plate, and a baffle at the end of the flow channel. A discharge port is opened on the bottom plate.
[0008] A liquid plugging assembly is fixed to the side of a smelting furnace. The assembly includes a fixed bracket, which includes a first crossbeam. A vertical cylinder is fixed on the first crossbeam. A connecting bracket is fixed to the bottom of the vertical cylinder. A pushing mechanism is fixed on the connecting bracket. The pushing mechanism includes a horizontally movable push rod. The end of the push rod has an inclined rod, and the end of the inclined rod is connected to a plug.
[0009] Furthermore, the connecting bracket includes a second crossbeam, on which a first vertical beam and a second vertical beam are fixed respectively. The horizontal cylinder includes a horizontal cylinder fixed to the side of the first vertical beam, and the push rod of the horizontal cylinder passes through the first vertical beam and the second vertical beam.
[0010] Furthermore, a guide rod is slidably connected to the top of the second crossbeam, the guide rod passing through the first crossbeam.
[0011] Furthermore, both the fixed bracket and the flow channel are provided with lugs, and the lugs are provided with connection holes for connecting to the smelting furnace.
[0012] Furthermore, the fixed bracket also includes a longitudinal beam, which is fixedly connected to the first crossbeam, and a diagonal brace is fixed between the longitudinal beam and the first crossbeam.
[0013] Furthermore, the push rod is also fixedly connected to a horizontal anti-deflection rod via a connecting rod, the anti-deflection rod passing through the second vertical beam.
[0014] Furthermore, the plug is a truncated cone.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. The discharge assembly has a simple structure, which allows the molten metal to be guided through the flow channel when it is discharged from the smelting furnace, so that its landing point is accurate. At the same time, it is more cost-effective and more reliable when sealing the discharge hole.
[0017] 2. The liquid blocking component can achieve rapid and precise opening and closing control of the discharge port at the end of the flow channel. The installation of the guide rod provides additional guidance for the movement of the pushing mechanism, ensuring that the push rod always maintains a straight line during horizontal movement, avoiding tilting, deflection or shaking of the push rod during movement, and further improving the movement accuracy and stability of the pushing mechanism.
[0018] 3. The liquid plugging assembly is fixed to the side of the smelting furnace, keeping a certain distance between the liquid plugging assembly and the high-temperature molten metal inside the furnace. This avoids direct contact with the high-temperature environment, effectively extending the service life of the liquid plugging assembly, reducing the frequency of component damage and replacement due to high temperatures, and lowering production costs.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0024] like Figures 1-3 The molten metal discharge assembly of the smelting furnace shown includes:
[0025] A flow channel 1 is fixed at the end of the discharge hole of the smelting furnace 6. The flow channel 1 includes a bottom plate 2, side plates 3 on both sides of the bottom plate 2, and a baffle 4 at the end of the flow channel 1. A discharge port 5 is opened on the bottom plate 2.
[0026] A liquid-blocking assembly is fixed to the side of a smelting furnace 6. The assembly includes a fixed bracket 7, which includes a first crossbeam 8. A vertical cylinder 9 is fixed on the first crossbeam. A connecting bracket 10 is fixed to the bottom of the vertical cylinder 9. A pushing mechanism is fixed on the connecting bracket 10. The pushing mechanism includes a horizontally movable push rod 11. The end of the push rod 11 has an inclined rod 12. The end of the inclined rod 12 is connected to a plug 13.
[0027] The process of using this utility model is as follows: When the molten metal in the smelting furnace 6 is about to be discharged, the plugging assembly is activated. Specifically, the pushing mechanism on the plugging assembly drives the push rod 11 to move backward, so that the plug 13 no longer blocks the discharge port of the smelting furnace 6. After the plug 13 moves backward, the vertical cylinder 9 drives the connecting bracket 10 to move upward, so that the plug 13 is removed from the area of the flow channel 1, thus not interfering with or obstructing the flow of the molten metal. When the molten metal flows in the flow channel 1, it will eventually fall from the discharge port 5 opened on the bottom plate 2 due to the obstruction of the baffle 4. Its falling trajectory and falling point are determined, so it can better receive the molten metal. When it is necessary to block the discharge port of the smelting furnace 6, the vertical cylinder descends, and the pushing mechanism pushes the push rod 11 forward again, so that the plug 13 blocks the discharge port of the smelting furnace 6. Since the end of the push rod 11 is connected to the tilting rod 12, only the lower end of the tilting rod 12 will come into contact with the molten metal phase, and will not damage the pushing mechanism.
[0028] Furthermore, the connecting bracket 10 includes a second crossbeam 14, with a first vertical beam 15 and a second vertical beam 16 fixed to both sides of the second crossbeam 14 respectively. A horizontal cylinder 17 is fixed to the side of the first vertical beam 15, and the push rod 11 of the horizontal cylinder 17 passes through the first vertical beam 15 and the second vertical beam 16. Specifically, the pushing mechanism of this utility model uses a horizontal cylinder 17. The push rod 11 of the horizontal cylinder 17 passes through the guide of the two vertical beams for precise extension and retraction, ensuring that the push rod 11 can accurately drive the plug 13 to move to the designated position, realizing reliable sealing and opening of the discharge hole, avoiding the problem of plug 13 offset or jamming due to the instability of the pushing mechanism, and improving the reliability of discharge control.
[0029] Furthermore, a guide rod 18 is slidably connected to the top of the second crossbeam 14, and the guide rod 18 passes through the first crossbeam 8. In order to ensure that the vertical cylinder 9 can move vertically without deflection when it drives the connecting bracket 10 to move upward, the guide rod 18 is slidably connected to the top of the second crossbeam 14.
[0030] Furthermore, both the fixed bracket 7 and the flow channel 1 are provided with lugs 19, and the lugs 19 are provided with connection holes for connecting to the melting furnace 6. Specifically, this utility model provides lugs 19 on both the fixed bracket 7 and the flow channel 1, and the connection holes on the lugs 19 are used to fix and connect to the melting furnace 6 with fasteners such as screws and nuts.
[0031] Furthermore, the fixed support 7 also includes a longitudinal beam 23, which is fixedly connected to the first crossbeam 8, and a diagonal brace 20 is fixed between the longitudinal beam and the first crossbeam 8. In order to make the fixed support 7 stronger, it includes a longitudinal beam for connecting to the smelting furnace 6, and a diagonal brace 20 is fixed between the first crossbeam 8 and the longitudinal beam.
[0032] Furthermore, the push rod 11 is also fixedly connected to a horizontal anti-deflection rod 21 via a connecting rod, and the anti-deflection rod 21 passes through the second vertical beam 16. Specifically, the top of the push rod 11 of this invention is also fixedly connected to an anti-deflection rod 21, which also serves as a guide for the push rod 11, preventing the push rod 11 from rotating during movement.
[0033] Furthermore, the plug 13 is a truncated cone 22. Specifically, in order to better seal the smelting furnace 6, the plug 13 can be set as a truncated cone 22. The shape of the truncated cone 22 makes the contact area between the plug 13 and the discharge hole larger, so that it can fit more tightly when sealing the discharge hole, effectively preventing the leakage of molten metal, improving the sealing reliability of the discharge hole, and ensuring the safety and stability of the smelting furnace 6 in the non-discharge state.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
