Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] Referring to Figures 1-5 , a protection structure for tapping a calcium carbide furnace provided by the present utility model includes a protective cover body 1. A flame-retardant and fire-proof layer 101 is lined on the inner side of the protective cover body 1. An opening 9 is provided at the upper end of the protective cover body 1, and a ventilation device 7 is provided on the opening 9. Symmetric exhaust ports 8 are provided at the upper end of the ventilation device 7, and exhaust fans 10 are provided in the exhaust ports 8. The ventilation device 7 can be used to discharge the hot air and harmful gases generated during the tapping process, and maintain the air quality of the operation environment. A splash-proof baffle 2 is provided on the inner side of the protective cover body 1. The splash-proof baffle 2 is used to prevent sparks and molten substances from splashing to the operator area during tapping. An insulation screen 3 is provided on the inner side of the splash-proof baffle 2. The insulation screen 3 is used to block heat radiation and reduce the influence of temperature on the operation area. A first slider 13 is fixedly provided at the bottom end of the splash-proof baffle 2, and the first slider 13 is connected to a first guide rail 6. A second slider 15 is fixedly provided at the bottom end of the insulation screen 3, and the second slider 15 is connected to a second guide rail 4. The splash-proof baffle 2 can move horizontally on the first guide rail 6, and the insulation screen 3 can move horizontally on the second guide rail 4. The first guide rail 6 and the second guide rail 4 enable the horizontal movement of the insulation screen 3 and the splash-proof baffle 2. During the tapping operation, they move to the use position. After the tapping is completed, they can be translated out of the operation position, which is more convenient for the subsequent operations of the operator. A safety door 5 is provided at the left end of the protective cover body 1. The safety door 5 provides a safe access passage for the operator in case of an emergency.
