Description

Technical Field

[0001] This utility model relates to the field of arc straightening machines, and in particular to a dust collection hood opening and sealing door switch structure. Background Technology

[0002] Electrolytic aluminum equipment is an indispensable core piece of equipment in the aluminum smelting industry. Its main function is to decompose alumina into aluminum metal and oxygen through an electrolytic reaction. Electrolytic aluminum equipment consists of several key components, including the electrolytic cell, anode, cathode, and power supply system. The coordinated action of these components ensures the smooth operation of the electrolysis process. Among the many components of electrolytic aluminum equipment, the dust collection hood sealing door opening and closing structure plays a crucial auxiliary role. The main function of this structure is to ensure the efficient collection and discharge of dust and harmful gases generated during the operation of the electrolytic cell, preventing these pollutants from polluting the environment and ensuring the health and safety of operators.

[0003] In existing aluminum electrolysis workshops, a residual electrode cooling device with a flue gas collection system is installed on the large surface of the dust collection hood. This ensures that all the dust, heat, and fluorides emitted from the residual electrode enter the electrolysis flue gas purification system, which not only meets environmental protection requirements but also greatly improves the working environment of the electrolysis workshop. The residual electrode cooling device also has the advantages of simple structure, good sealing performance, and easy mobility. Its disadvantages are that the device has high structural requirements during the residual electrode cooling process, the equipment cost is relatively high, and the maintenance cost is also relatively increased.

[0004] To address this issue, a dust collection hood sealing door opening and closing structure is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of high equipment cost and high maintenance cost in the existing technology, this utility model provides a dust collection hood opening and sealing door switch structure.

[0006] This utility model is achieved using the following technical solution:

[0007] A dust collection hood opening and closing mechanism includes a dust collection hood body with at least one groove-shaped first opening. A protective door is movably mounted on the top of the dust collection hood body near the first opening. A bracket is welded to one side of the protective door, and a first electric push rod is mounted on both ends of the bracket. A first guide rod is built into the first electric push rod, and the front end of the first guide rod is connected to the dust collection hood body. A second opening is provided on the protective door, and a slide rail is provided on the top of the protective door near the second opening. Two slidable connecting sliders are mounted on the slide rail, and the two connecting sliders are movably connected to the first door and the second door, respectively.

[0008] As a preferred embodiment of this utility model, a second electric push rod is provided on the first door, the second electric push rod has a built-in second guide rod, and the front end of the second guide rod is connected to the second door.

[0009] As a preferred embodiment of this utility model, the first gate and the second gate are closed to form a third opening, and a steel claw is provided in the third opening.

[0010] As a preferred embodiment of this utility model, a mounting base is provided on the top of the shield door near the second opening, and movable rods are symmetrically arranged at both ends of the mounting base. A positioning plate is provided at the end of the movable rod, and a return spring is provided on the movable rod.

[0011] As a preferred embodiment of this utility model, the first door and the second door are designed symmetrically.

[0012] As a preferred embodiment of this utility model, an external connector is provided on one side of the dust collection hood body, and reinforcing ribs are cross-welded to the inner side wall of the dust collection hood body.

[0013] In a preferred embodiment of this utility model, the protective door and the first opening are a combined and matched structure, and the number of them is the same.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] 1. By controlling the first electric push rod and its built-in first guide rod, the shield door moves towards the first opening. When the first guide rod is fully extended, the shield door tightly fits the first opening, ensuring a seal.

The front end of the second guide rod 31 is connected to the second door 33. When the second electric push rod 3 is driven to move, the second guide rod 31 moves within the range of the first electric push rod 22. At the same time, the connecting slider 35 on the first door 32 and the second door 33 slides synchronously along the slide rail 34 to ensure that the first door 32 and the second door 33 open and close synchronously.

[0030] Specifically, the first gate 32 and the second gate 33 close to form a third opening 51, and a steel claw 5 is installed inside the third opening 51.

[0031] In this embodiment, when the first door 32 and the second door 33 are closed, a third opening 51 is formed. A steel claw 5 is provided in the third opening 51. When the first door 32 and the second door 33 are closed, the steel claw 5 is clamped to ensure sealing and prevent dust leakage. The end of the steel claw 5 is connected to an external device. After the door 2 and the first opening 13 are tightly fitted, the steel claw 5 extends in and then drives the second electric push rod 3 to gradually tighten the steel claw 5.

[0032] Specifically, a mounting base 41 is provided on the top of the shield door 2 near the second opening 14. Movable rods 43 are symmetrically arranged at both ends of the mounting base 41.

When the first shield door 32 and the second shield door 33 close and clamp the steel claw 5, the positioning plate 4 is in close contact with the surface of the steel claw 5 to ensure sealing.

[0034] Specifically, the first door 32 and the second door 33 are designed symmetrically.

[0035] In this embodiment, the first door 32 and the second door 33 are symmetrically designed. Both the first door 32 and the second door 33 are provided with connecting sliders 35, which move synchronously relative to each other on the slide rail 34 to ensure consistent opening and closing.

[0036] Specifically, an external connector 11 is provided on one side of the dust collection hood body 1, and reinforcing ribs 12 are cross-welded to the inner side wall of the dust collection hood body 1.

[0037] In this embodiment, an external connector 11 is provided on one side of the dust collection hood body 1 for connecting to external equipment. Reinforcing ribs 12 are cross-welded inside the dust collection hood body 1 to increase the overall structural stability and ensure that it does not deform under high-intensity use environment.

[0039] In this embodiment, the shield door 2 and the first opening 13 are a combined matching structure with the same number to ensure that they correspond one-to-one during installation. When the shield door 2 and the first opening 13 are tightly fitted together, a complete sealing system is formed, which effectively prevents dust from leaking out.

[0040] The principle of this utility model is as follows: When the door needs to be closed, the first guide rod 23 built into the first electric push rod 22 is extended, causing the shield door 2 to move towards the first opening 13. When the first guide rod 23 built into the first electric push rod 22 is fully extended, the shield door 2 tightly fits the first opening 13. Then, the steel claw 5 is inserted into the device through an external device, driving the second guide rod 31 built into the second electric push rod 3 to retract. The second guide rod 31 moves within the range of motion of the first electric push rod 22. At the same time, the connecting slider 35 on the first shield door 32 and the second shield door 33 slides synchronously along the slide rail 34. When the first shield door 32 and the second shield door 33 are closed, the steel claw 5 is clamped. At the same time, when the first shield door 32 and the second shield door 33 are closed and tightly pressed against the steel claw 5, the positioning plate 4 presses the steel claw 5 tightly under the action of the return spring 42 to ensure sealing, prevent dust leakage, and improve overall efficiency.
