Description

Technical Field

[0001] This utility model relates to the technical field of smelting furnace control equipment, specifically to an emergency discharge device for the siphon inlet of a holding furnace. Background Technology

[0002] When aluminum seepage occurs in the smelting furnace, the molten aluminum needs to be transferred from the furnace to the holding furnace. Temperature sensors monitor the first pouring channel; when aluminum seepage occurs, the molten aluminum flows into the first pouring channel, then into the second pouring channel, and finally into the holding furnace. A baffle is installed at the contact point between the holding furnace inlet and the first pouring channel. Current equipment requires manual opening of the baffle, which poses a safety hazard due to the high temperature of the molten aluminum. Furthermore, manual operation may result in errors or delays due to various factors when facing sudden aluminum seepage.

[0003] Therefore, there is an urgent need for an emergency discharge device that can automatically open the baffle in the event of an aluminizing accident. Summary of the Invention

[0004] To address the safety hazard posed by the need for manual opening of existing baffles, this invention proposes an emergency discharge device for the siphon inlet of a heat preservation furnace. A control module is electrically connected to an aluminum leakage alarm device, controlling a telescopic mechanism to raise and lower the baffle, thereby opening and closing the baffle automatically.

[0005] To achieve the above objectives, this utility model proposes an emergency discharge device for the siphon inlet of a holding furnace, comprising a holding furnace, a smelting furnace, a first inverted flow channel, and a second inverted flow channel. The smelting furnace is connected to the first inverted flow channel and is equipped with an aluminum leakage alarm device. The first inverted flow channel is connected to the second inverted flow channel, and the other side of the second inverted flow channel is connected to the holding furnace. A sealing mechanism is provided above the second inverted flow channel near the holding furnace, and an opening is provided on the second inverted flow channel corresponding to the sealing mechanism.

[0006] The sealing mechanism includes a telescopic mechanism, a bracket, and a baffle. The telescopic mechanism is fixedly mounted on the bracket. One end of the telescopic mechanism is fixed to the bracket, and the other end is connected to the baffle. The telescopic mechanism is equipped with a control module, and the input end of the control module is connected to the aluminum leakage alarm device.

[0007] The baffle is a plate-shaped structure made of asbestos material. The width of the baffle is smaller than the width of the opening, and the length and width of the baffle are both greater than the length and width of the siphon opening.

[0008] The support includes a horizontal section and a vertical section. The horizontal section is rotatably connected to the heat preservation furnace, and the vertical section is fixed to the telescopic mechanism. The vertical section and the horizontal section are an integrated structure.

[0009] Furthermore, the longitudinal segment is a square structure with an opening at the top and a hollow interior;

[0010] The telescopic mechanism includes a cylinder, the housing of which is disposed within the longitudinal section, and the moving end of the cylinder is connected to a baffle.

[0011] The cylinder is equipped with a two-position three-way solenoid valve, which is connected to the air source. The two-position three-way solenoid valve is electrically connected to the control module.

[0012] The longitudinal section provides protection for the cylinder. The upper and lower chambers of the cylinder are connected to the two outlets of a two-position three-way solenoid valve, respectively. The inlet of the two-position three-way solenoid valve is connected to the air source. The extension and retraction of the cylinder are controlled by energizing and de-energizing the coil of the two-position three-way solenoid valve. The actuator control is simple and easy to implement.

[0013] Furthermore, a first side plate is provided between the telescopic mechanism and the baffle, and a second side plate is provided at the bottom end of the longitudinal section. Both the first side plate and the second side plate are square plates.

[0014] A pulley is provided at the corner of the first side plate, and four pulleys are fixed to the first side plate respectively. A guide rod is provided at the corner of the second side plate, and four guide rods are fixed to the second side plate respectively. The pulleys and guide rods are in corresponding contact.

[0015] A first side plate and a second side plate are provided. A pulley is installed on the first side plate and a guide rod is installed on the second side plate. Since the positions of the first side plate and the second side plate are relatively fixed, when the cylinder is actuated, the pulley moves along the guide rail to limit the movement trajectory of the baffle and improve the stability of the baffle during the movement process.

[0016] Furthermore, the transverse segment has a long strip-shaped structure;

[0017] The top of the heat preservation furnace is provided with a mounting base, which is a cylindrical structure. A bearing is fixedly installed inside the mounting base, and a pin is fixedly installed on the inner ring surface of the bearing. The other end of the pin is fixed to the transverse section.

[0018] The two are connected by a pivot pin. After the baffle is raised, the sealing mechanism can be moved away from the second inverted flow channel by rotating the transverse section to avoid affecting the subsequent work.

[0019] Furthermore, the aluminum leakage alarm device includes a temperature sensor, and the control module includes a controller, the input terminal of which is connected to the output terminal of the temperature sensor.

[0020] The temperature sensor combined with the controller circuit has a simple structure and is easy to control. The controller includes a PLC controller and an MCU chip.

[0021] The beneficial effects of this utility model through the above technical solution are as follows:

[0022] This invention enables the automatic opening of the baffle after aluminum leakage occurs. A sealing mechanism is provided, with an opening on the second inverted flow channel corresponding to the sealing mechanism. The sealing mechanism includes a telescopic mechanism, a support, and a baffle. The opening facilitates the entry and exit of the baffle into the second inverted flow channel. One end of the telescopic mechanism is fixed to the support, and the other end is connected to the baffle. The telescopic mechanism is equipped with a control module, the input of which is connected to the aluminum leakage alarm device. When the aluminum leakage alarm device responds, the control module controls the telescopic mechanism to raise the baffle, thereby opening the channel.

[0023] In addition, the horizontal section of the support is rotatably connected to the heat preservation furnace, and the baffle can flexibly avoid the second inverted furnace flow channel after it is opened, which facilitates subsequent operations. Attached Figure Description

The smelting furnace 16 is connected to the first reverse flow channel 17, and the smelting furnace 16 is equipped with an aluminum leakage alarm device. The first reverse flow channel 17 is connected to the second reverse flow channel 2, and the other side of the second reverse flow channel 2 is connected to the holding furnace 1. The device is characterized in that a sealing mechanism is provided above the second reverse flow channel 2 near the holding furnace 1, and an opening is provided on the second reverse flow channel 2 corresponding to the sealing mechanism.

[0031] The sealing mechanism includes a telescopic mechanism 4, a bracket 5, and a baffle 3. The telescopic mechanism 4 is fixedly installed on the bracket 5. One end of the telescopic mechanism 4 is fixed to the bracket 5, and the other end is connected to the baffle 3. The telescopic mechanism 4 is equipped with a control module, and the input end of the control module is connected to the aluminum leakage alarm device.

[0032] The baffle 3 is a plate-shaped structure made of asbestos material. The width of the baffle 3 is smaller than the width of the opening, and the length and width of the baffle 3 are both greater than the length and width of the siphon opening.

[0033] The support 5 includes a horizontal section and a vertical section. The horizontal section is rotatably connected to the heat preservation furnace 1, and the vertical section is fixed to the telescopic mechanism 4. The vertical section and the horizontal section are an integrated structure.

[0034] The longitudinal section is a square structure with an opening at the top and a hollow interior;

[0035] The telescopic mechanism 4 includes a cylinder, the housing of which is disposed in the longitudinal section, and the moving end of the cylinder is connected to the baffle 3.

[0036] The cylinder is equipped with a two-position three-way solenoid valve 6, which is connected to the air source. The two-position three-way solenoid valve 6 is electrically connected to the control module.

[0037] A first side plate 7 is provided between the telescopic mechanism 4 and the baffle 3, and a second side plate 8 is provided at the bottom of the longitudinal section. Both the first side plate 7 and the second side plate 8 are square plates.

[0038] A pulley 9 is provided at the corner of the first side plate 7, and four pulleys 9 are fixed to the first side plate 7 respectively. A guide rod 10 is provided at the corner of the second side plate 8, and four guide rods 10 are fixed to the second side plate 8 respectively. The pulleys 9 and guide rods 10 are in corresponding contact.

[0039] The transverse segment has a long strip-shaped structure;

[0040] The top of the heat preservation furnace 1 is provided with a mounting base 11, which is a cylindrical structure. A bearing is fixedly installed inside the mounting base 11, and a pin 12 is fixedly installed on the inner ring surface of the bearing.

[0041] The aluminum leakage alarm device includes a temperature sensor 13, and the control module includes a controller 14, the input terminal of which is connected to the output terminal of the temperature sensor 13.

[0043] During operation, temperature sensor 13 monitors the temperature inside the first inverted flow channel 17 in real time. When aluminum leakage occurs, the temperature sensor 13 detects an increase in temperature, exceeding the temperature threshold set by controller 14. Controller 14 energizes the coil of the two-position three-way solenoid valve 6, allowing air to enter the lower air chamber and opening the upper air chamber. The piston rod moves upward, causing the first side plate 7, pulley 9, and baffle 3 to move upward. Pulley 9 moves along guide rod 10 closer to the second side plate 8, opening the second inverted flow channel 2. Then, the transverse section is rotated to move the sealing mechanism away from the second inverted flow channel 2.

[0044] Once the operation is complete, reset the horizontal section and press the reset button. The controller 14 will de-energize the coil of the two-position three-way solenoid valve 6, allowing air to enter the upper gas chamber and opening the lower gas chamber. The piston rod will drive the baffle 3 to move down, and the second inverted flow channel 2 will be closed.
