Description

Technical Field

[0001] This utility model relates to a smelting furnace discharge port switch device. Background Technology

[0002] In the aluminum and aluminum alloy smelting and casting industry, the smelting furnace is a core piece of equipment, and the control of the discharge of molten aluminum directly affects production efficiency, product quality, and operational safety. In traditional molten aluminum discharge systems, the opening and closing of the discharge port mainly relies on manual operation of a mechanical gate: the operator needs to hold a long-handled tool (such as an iron hook, lever, etc.) and use physical force to push the gate to move in order to control the opening and closing of the discharge port.

[0003] The operational characteristics and limitations of existing technologies are mainly reflected in the following aspects:

[0004] Before releasing the flow, operators need to closely observe the status of the discharge port and manually adjust the gate opening using a long-handled tool. After the flow is released, the gate is closed again using the tool to complete a single discharge cycle. Due to the slow response speed of manual operation, the slow gate opening and closing action, and the heavy weight of the long-handled tool, the operation requires a lot of physical strength. Especially in large-scale, continuous production scenarios, operators are prone to fatigue, further reducing operational accuracy and work efficiency.

[0005] To address the above technical issues, this paper proposes a smelting furnace vent switch device. Utility Model Content

[0006] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a smelting furnace vent switch device.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is: a smelting furnace vent switch device, including a smelting furnace, a vent provided on the smelting furnace, a swing rod that is driven by a drive mechanism to swing up and down on the smelting furnace, a non-end of a connecting rod hinged to the bottom end of the swing rod, a plug for sealing the vent provided at one end of the connecting rod, and a counterweight component with adjustable position provided at the other end of the connecting rod;

[0008] A detachable pull rod is also connected between the smelting furnace and the swing rod to facilitate pulling the swing rod when the plug seals the outlet.

[0009] Preferably, the drive mechanism includes a cylinder, the cylinder body of which is hinged to the non-end of the swing rod, and the end of the piston rod of which is hinged to the melting furnace.

[0010] Preferably, the plug and the connecting rod are fixedly connected.

[0011] Preferably, the counterweight assembly includes a counterweight slider, which is slidably connected to the connecting rod, and a set screw for tightening the connecting rod is screwed onto the counterweight slider.

[0012] Preferably, a probe for detecting molten aluminum is also fixedly connected to the connecting rod, and the probe is located on the rear side of the plug.

[0013] Preferably, the pulling rod is a threaded rod, one end of which is hinged to the smelting furnace via a vertical shaft, and the other end of which is screwed with at least two locking nuts.

[0014] Preferably, an adapter plate is fixed on the swing rod, and the adapter plate has a connection notch for the threaded rod to be inserted into the swing rod.

[0015] Preferably, the smelting furnace is provided with an inclined discharge trough, the high end of which is connected to a discharge port to receive the molten aluminum flowing out along the discharge port.

[0016] Preferably, the plug is a conical head that gradually widens from front to back, and its front end is a hemispherical head.

[0017] Preferably, the counterweight slider is annular in shape and is fitted onto the outer periphery of the connecting rod.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] When the swing rod is in the upper swing position, the vent outlet of the smelting furnace is in the open state. At this time, because there is a counterweight component on the connecting rod, the plug end of the connecting rod is suspended above the vent channel. When the swing rod swings downward, the plug approaches the vent outlet and contacts the inner peripheral wall of the inclined surface of the vent outlet. The connecting rod rotates adaptively relative to the swing rod until the plug completely blocks the vent outlet.

[0020] To prevent sudden failure of the drive mechanism, a tie rod is used to connect the smelting furnace and the swing rod. Even if the drive mechanism suddenly fails, the tie rod can hold the swing rod to prevent the vent from being opened.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] like Figures 1-3 As shown, this embodiment provides a smelting furnace vent switch device, including a smelting furnace 1, a vent 2 provided on the smelting furnace, a swing rod 3 that is driven by a drive mechanism to swing up and down on the smelting furnace, a connecting rod 4 with the non-end of the bottom of the swing rod being hinged to the bottom of the swing rod, a plug 5 for sealing the vent 2 is provided at one end of the connecting rod, and a counterweight component 6 with an adjustable position is provided at the other end of the connecting rod.

[0030] A detachable pull rod 7 is also connected between the smelting furnace and the swing rod to facilitate pulling the swing rod when the plug seals the outlet.

[0031] In this embodiment of the present invention, the driving mechanism includes a cylinder 8, the cylinder body of which is hinged to the non-end of the swing rod, and the end of the piston rod of which is hinged to the melting furnace.

[0032] In this embodiment of the invention, the plug and the connecting rod are fixedly connected.

[0033] In this embodiment of the utility model, the counterweight assembly includes a counterweight slider 9, which is slidably connected to the connecting rod, and a set screw 10 for tightening the connecting rod is screwed onto the counterweight slider.

[0034] In this embodiment of the invention, a probe 11 for detecting molten aluminum is also fixedly connected to the connecting rod, and the probe is located on the rear side of the plug.

[0035] In this embodiment of the utility model, the pulling rod is a threaded rod, one end of which is hinged to the smelting furnace via a vertical shaft 12, and the other end of which is screwed with at least two locking nuts 13.

[0036] In this embodiment of the utility model, an adapter plate 14 is fixed on the swing rod, and a connection notch 15 is provided on the adapter plate for the threaded rod to be inserted into the swing rod.

[0037] In this embodiment of the present invention, the smelting furnace is provided with an inclined discharge trough 16, the high end of which is connected to a discharge port to receive the molten aluminum flowing out along the discharge port.

[0038] In this embodiment of the invention, the plug is a conical head that gradually widens from front to back, and its front end is a hemispherical head.

[0039] In this embodiment of the invention, the counterweight slider is circular in shape and coaxially fitted onto the outer periphery of the connecting rod.

[0040] In this embodiment of the invention, the working principle of the smelting furnace vent switch device is as follows:

[0041] When the piston rod of the cylinder extends and the swing rod is in the upper swing position, the discharge port is in the open state. At this time, because there is a counterweight component on the connecting rod, the plug end of the connecting rod is suspended above the discharge channel.

[0042] As the piston rod of the cylinder begins to retract and the swing rod gradually swings downwards, the plug gradually approaches the vent and contacts the inner circumferential wall of the vent's inclined surface (the vent is an everted opening that gradually widens from front to back). The connecting rod rotates adaptively relative to the swing rod until the plug completely blocks the vent. After the vent is completely blocked, molten aluminum no longer flows out into the venting tank, and the probe's head is located inside the venting tank near the vent. Once the molten aluminum inside the venting tank near the vent has been drained, the probe begins detection; any leakage of molten aluminum from the vent will be detected by the probe.

[0043] To prevent sudden cylinder failure, after the vent is closed, the operator can rotate the pull rod so that the nut end of the pull rod is inserted into the connection notch, and slightly tighten the nuts on both sides of the connection notch. The pull rod is used to connect the smelting furnace and the swing rod. Even if the cylinder suddenly fails, the pull rod can hold the swing rod and prevent the vent from being opened due to failure.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
