Description

Technical Field

[0001] This utility model belongs to the field of magnetic powder processing technology, and in particular relates to a sealing device for the magnetic powder inlet of a kiln. Background Technology

[0002] During magnetic powder processing, magnetic powder is placed in a high-temperature environment in a kiln, which reduces the gap between powder particles. The particle surface melts and then cools and solidifies, thereby tightly binding the powder particles together to form a strong magnetic material. In this process, phenomena such as mass transfer and grain growth may also occur, which can change the physical and chemical properties of the magnetic powder.

[0003] Magnetic powder is mostly heated and processed in kilns. After the magnetic powder enters the kiln, the kiln inlet needs to be sealed to maintain the atmosphere and temperature inside the kiln and prevent external impurities from entering and contaminating the magnetic powder. Therefore, a kiln magnetic powder inlet sealing device is needed. The kiln inlet can be sealed through a sealing structure to prevent leakage during the processing of magnetic powder in the kiln and ensure the stability of magnetic powder processing. Summary of the Invention

[0004] The purpose of this invention is to provide a kiln magnetic powder inlet sealing device, which can seal the kiln inlet through a sealing structure to prevent leakage during magnetic powder processing, thus ensuring the stability of magnetic powder processing and solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A kiln magnetic powder inlet sealing device includes a fixed frame fixedly connected to the right side of the kiln body. A cover plate is rotatably connected to the inner cavity of the fixed frame. A slide is provided in the inner cavity of the fixed frame. Limiting strips are fixedly connected to both sides of the slide. Sliding grooves are opened on the front and back of the inner cavity of the fixed frame. The limiting strips are adapted to the sliding grooves. A connecting frame is rotatably connected to the bottom of the slide. Two symmetrical connecting plates are fixedly connected to the right side of the cover plate. The connecting plates are rotatably connected to the connecting frame. A cylinder is fixedly installed on the top of the fixed frame by bolts. The output end of the cylinder passes through the fixed frame and is fixedly connected to the top of the slide. An opening and closing door is provided on the right side of the kiln body. A sealing frame is fixedly connected to the right side of the kiln body. The cover plate is adapted to the sealing frame.

[0006] Preferably, the inner cavity of the connecting frame is fixedly connected with a transverse reinforcing rod, and the top of the slide is fixedly connected with a reinforcing plate.

[0007] Preferably, a handle is fixedly connected to the right side of the cover plate, and the surface of the handle is provided with anti-slip texture.

[0008] Preferably, the carriage is L-shaped, the left side of the carriage is in contact with the furnace body, and the reinforcing plate is triangular.

[0009] Preferably, the connecting frame is in an inclined state, the side of the connecting plate away from the cover plate is arc-shaped, and the switch door is located in the inner cavity of the sealing frame.

[0010] The beneficial effects of this utility model are: 1. This utility model uses a starting cylinder to make the slide slide downward in the inner cavity of the fixed frame, and the slide pushes the cover plate to flip through the connecting frame, so that the cover plate flips and latches onto the right side of the furnace body. At this time, the cover plate covers the surface of the opening and closing door, and the cover plate matches the sealing frame. This achieves the sealing of the kiln inlet through the sealing structure, avoiding leakage when the kiln processes magnetic powder, and ensuring the stability of magnetic powder processing. 2. By setting up a reinforcing plate, this utility model supports the slide when the slide pushes the connecting frame to move, preventing the slide from bending and deforming due to the acrylic, thus ensuring the stability of the slide.
