[0018] In order to make the technical means, creative features, objectives and effects of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0019] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0020] Example 1

[0021] like Figure 1-4As shown, an industrial furnace covering structure includes a furnace body 1, a furnace cover 6 arranged at the top of the furnace body 1, the top of the furnace cover 6 is bolted with a connecting rod 8 rotatably installed on the furnace body 1, one end of the connecting rod 8 is provided with a hydraulic rod 7 installed on the side of the furnace body 1, a plurality of limiting covers 2 are arranged at the edge of the furnace cover 6, a pushing block 5 in contact with the limiting cover 2 is arranged at the bottom of the other end of the connecting rod 8, and a plurality of groups of electromagnets 4 connected with the limiting cover 2 and the limiting shell 3 are arranged above the furnace body 1.

[0022] A connecting block is provided on one side of the middle part of the limiting cover 2, and one end of the limiting cover 2 and one end of the pushing block 5 are both provided with inclined surfaces, and the inclination angles of the inclined surface of the limiting cover 2 and the inclined surface of the pushing block 5 are adapted to each other, wherein, in order to prevent the limiting cover 2 from blocking the furnace cover 6, when the furnace cover 6 is fully placed, the limiting cover 2 is not connected to the furnace cover 6, and the limiting cover 2 is continuously moved under the operation of the electromagnet 4, so that the limiting cover 2 is wrapped around the edge of the furnace cover 6, further sealing the furnace cover 6 and the furnace body 1.

[0023] A notch is provided at one end of the connecting block of the limiting cover 2, and one end of the electromagnet 4 is located inside the notch of the connecting block of the limiting cover 2, wherein one electromagnet 4 is composed of two electromagnets 4 with repulsive force between them, wherein one electromagnet 4 is installed on the limiting cover 2 and the other is installed on the limiting shell 3, so that the electromagnet 4 can drive the limiting cover 2 to move.

[0024] Limiting plates are provided on one side of the limiting cover 2 and on both sides of the connecting block. A limiting shell 3 connected to the limiting plate of the limiting cover 2 is provided at the top of the furnace body 1. The limiting plate of the limiting cover 2 is inserted into the inner side of the limiting shell 3. Through the cooperation between the limiting plate of the limiting cover 2 and the limiting shell 3, the upward movement of the limiting cover 2 can be restricted, thereby improving the tightness of the furnace cover 6 moving upward again.

[0025] The number of the plurality of limiting covers 2 is at least four, and the size of one limiting cover 2 is one-fourth of a circle, the end of the limiting cover 2 is L-shaped, the limiting cover 2 is at the edge of the furnace cover 6, the other end of the connecting rod 8 is cross-shaped, and the four bottoms of one end of the connecting rod 8 are provided with push blocks 5.

At the same time, the push block 5 can assist the limiting cover 2 to move toward the furnace cover 6 to minimize the distance between the limiting cover 2 and the furnace cover 6.

[0026] Working principle:

[0027] When in use, the hydraulic rod 7 drives the connecting rod 8 to make a lever movement on the furnace body 1, so that the connecting rod 8 drives the furnace cover 6 to cover the furnace door of the furnace body 1, and at the same time, the other end of the connecting rod 8 drives the pushing block 5 to connect with the connecting block of the limiting cover 2, so that the pushing block 5 squeezes the limiting cover 2, and the limiting cover 2 moves to the side of the furnace cover 6, and through the repulsive force generated between the two electromagnets 4, the limiting cover 2 is wrapped around the edge of the furnace cover 6. At the same time, the limiting plate of the limiting cover 2 is also inserted into the inner side of the limiting shell 3, so that the upward movement of the limiting cover 2 is limited, the covering work of the furnace cover 6 is more convenient, and the covering of the furnace cover 6 is more stable and the sealing is improved.
