Description

Technical Field

[0001] The utility model relates to the technical field of fused magnesia furnaces, in particular to an automatic unloading device for a large crystal fused magnesia furnace. Background Art

[0002] The electric furnace body for smelting fused magnesia consists of a furnace shell and a furnace bottom. The furnace shell is generally welded from 4 to 6 mm steel plates. Its shape is mostly cylindrical with a large diameter at the bottom and a small diameter at the top and a gradual transition. A few cylinders are triangular. Some furnace bodies are also equipped with a loop about 500 mm high at the top.

[0003] When unloading the fused magnesia furnace, an automatic unloading device is required. However, when the automatic unloading device is in use, the automatic unloading device does not have the function of screening large crystals and adjusting the height, which leads to the inability to screen out unqualified large crystals and inconvenient unloading. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an automatic unloading device for a large crystal fused magnesia furnace, which has the advantages of being able to screen and adjust the height of the automatic unloading device, thereby solving the problem that the automatic unloading device does not have the screening and height adjustment functions.

The two ends of the inner cavity of the discharge box are fixedly connected with a motor, and a cam is arranged at the output end of the motor. The left side of the front and back sides of the discharge box are provided with a first concave plate, and the right side of the front and back sides of the discharge box are provided with a second concave plate, and the inner cavities of the first concave plate and the second concave plate are both sleeved with a connecting plate, and sliding blocks are arranged on both sides of the inner cavity of the connecting plate, and sliding grooves adapted to the sliding blocks are arranged on both sides of the inner cavities of the first concave plate and the second concave plate, and limiting holes are arranged at the bottom of the inner cavities of the first concave plate and the second concave plate, and the inner cavity of the connecting plate is provided with a clamping hole, and the inner cavity of the clamping hole is sleeved with a fixing bolt, and one end of the fixing bolt is threadedly connected with the limiting hole. When the height of the discharge box needs to be adjusted, the fixing bolt is screwed, When the fixing bolt is removed from the card hole and the limit hole, the first concave plate and the second concave plate can be moved upward, and the first concave plate and the second concave plate can be moved on the surface of the connecting plate, and the first concave plate and the second concave plate can be cooperated with the slider and the slide groove on the connecting plate to move, and the height of the unloading box can be driven by the first concave plate and the second concave plate to adjust the height. When the unloading box moves to the required height, the fixing bolt is inserted into the card hole and the limit hole, and the first concave plate and the second concave plate can be fixed to the connecting plate. At this time, it is more convenient to unload. When the large crystals fall into the unloading box, the motor runs, and the cam is driven by the motor to rotate, and the leak plate is driven by the cam to move up and down. The baffle plate and the spring cooperate with the leak plate to move up and down. When the leak plate moves up and down, the large crystals on the leak plate can be screened, and the large crystals that do not meet the specifications fall into the bottom of the unloading box through the leak hole. At this time, the large crystals that meet the specifications fall into the first collection box of the peripheral device through the left side of the leak plate, and the large crystals that do not meet the specifications fall into the second collection box of the peripheral device through the left side of the unloading box.
