Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbide furnaces, in particular to an emergency device for a furnace outlet of a calcium carbide furnace. Background Art

[0002] During the calcium carbide production process, after becoming molten in the calcium carbide furnace, the carbide flows into the carbide pot on the discharge cart. It is then transported by the discharge track to the workshop corridor or the calcium carbide packaging workshop for cooling. During this process, the molten carbide can splash out of the discharge port, causing burns, damage to discharge equipment, and carbide gas explosions. Emergency devices are typically installed at the discharge port of the calcium carbide furnace to prevent molten carbide from splashing out of the furnace eye. Therefore, it is essential to design an emergency device to prevent calcium carbide leakage.

[0003] However, the existing emergency device is fixed at the furnace outlet and cannot be moved flexibly when in use, causing inconvenience in use. In addition, the existing emergency device adopts a single-sided splash-proof device. When in use, the splashing calcium carbide touches the single-sided splash-proof device and will still splash outward. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide an emergency device for calcium carbide to be discharged from the furnace in response to the deficiencies in the above-mentioned prior art. The device has a simple structure and a reasonable design. Through a movable setting, it can realize rapid replacement after the furnace trolley leaves, thereby preventing the molten calcium carbide from splashing out of the furnace outlet. At the same time, the three-sided splash-proof setting can effectively prevent the calcium carbide from splashing out.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: an emergency device for the outlet of a calcium carbide furnace, comprising: a locking device, a sliding guide rail, a roller, a fire baffle, a fire baffle driving device, a connecting block, a first fire baffle, and a slider. The sliding guide rail is fixedly arranged on both sides of the outlet of the calcium carbide furnace, a slider is arranged on the sliding guide rail, a connecting block is fixedly arranged on the slider, the connecting block is fixedly arranged at the bottom of the fire baffle, a fire baffle driving device is arranged on the inner side of the fire baffle, a first fire baffle is fixedly arranged on the inner side of the fire baffle, and a locking device is arranged on the side of the connecting block.

[0006] Furthermore, a locking groove is provided on the side of the sliding guide rail.

[0007] Furthermore, the locking device includes a locking bolt and a locking slider. The locking slider is fixedly connected to the connecting block, and the locking slider is locked by the locking bolt.

[0008] Furthermore, the fire baffle driving device includes a cylinder, a telescopic rod, a second fire baffle, a long groove, a guide column, and a fixed block. The cylinder is fixed on the inner side of the fire baffle cover, and the telescopic rod at the output end of the cylinder is fixedly connected to the second fire baffle through a fixed block. The second fire baffle is arranged in the guide column, and a long groove is provided on the second fire baffle.

[0009] Furthermore, rollers are provided at the bottom of the fire shield.

[0010] The utility model has the following beneficial effects:

[0011] The utility model has a reasonable and compact structure and can achieve flexible movement through rollers. After the furnace trolley leaves, it can be quickly replaced by moving on the sliding guide rail. The fire baffle driving device can make the second fire baffle move upward in the guide column and then be located above the furnace outlet. When splashing occurs in the furnace eye of the calcium carbide furnace, the fire baffle driving device makes the second fire baffle move downward in the guide column. Finally, the second fire baffle, the first fire baffle and the fire shield form a three-sided splash-proof arrangement to effectively block the calcium carbide splashing phenomenon, prevent accidents and reduce safety risks. The long groove on the second fire baffle can be used to place the furnace steel chisel. When there is a furnace steel chisel in the furnace eye, it can be directly lowered without pulling out the furnace steel chisel, thereby shortening the emergency operation time.
