Abstract
Description
Technical Field
[0001] This utility model relates to a dust removal hood, specifically a mold repair dust removal hood. Background Technology
[0002] Mold repair generates a lot of smoke and dust, which, if not treated, can affect the environment and human health.
[0003] Currently, the method for capturing smoke and dust is to install a fixed hood. However, a fixed hood is very inconvenient to use. If the hood is too large, it will not only take up space but also affect the hoisting of ingots. If the hood is too small, the effect of capturing smoke and dust will not be good. Utility Model Content

[0006] The top of the movable cover is provided with a first smoke-blocking structure, and the fixed cover is provided with a second smoke-blocking structure, which is fastened to the first smoke-blocking structure.
[0007] The fixed cover includes a fixed frame and a top cover. The top cover is fixed to the top of the fixed frame and is connected to the pipe. The pipe is also connected to a main pipe. The second smoke-blocking structure is fixed to the inner side of the fixed frame.
[0008] The movable cover includes a first movable frame and a second movable frame. Both the first movable frame and the second movable frame are gantry structures. The first movable frame is higher than the second movable frame and the two are arranged in parallel. A movable top cover is provided on the top. The movable top cover is an inclined structure. The first smoke-blocking structure is located on the top of the first movable frame. The first movable frame is always located inside the fixed cover. The walking component is provided at the bottom of the first movable frame and the second movable frame.
[0009] The first smoke-blocking structure includes a first upright plate and at least two first sawtooth structures, the at least two first sawtooth structures being fixed to the first upright plate, and the first upright plate being fixed to the top of the first movable frame; the second smoke-blocking structure includes a second upright plate and at least three second sawtooth structures, the at least three second sawtooth structures being fixed to the second upright plate, and the second upright plate being fixed to the fixed frame; the at least two first sawtooth structures and the at least three second sawtooth structures mesh with each other.
[0010] In summary, this utility model achieves the following technical effects:
[0011] This utility model combines a movable cover and a fixed cover, allowing the movable cover to be moved for easy use. It not only occupies little space but also does not affect the hoisting of ingots. Combined with the smoke-blocking structure, it reduces the escape of smoke and dust and has a good smoke-absorbing effect. Attached Figure Description

[0026] Example:
[0027] Figure 1It is a dust removal hood for mold repair, including a fixed hood 1 and a movable hood 2. The fixed hood 1 is provided with a pipe 3 for extracting smoke and dust. The first side of the movable hood 2 is always located inside the fixed hood 1. The bottom of the movable hood 2 is provided with a walking component 204 so that the movable hood 2 can move to the inside or outside of the fixed hood 1.
[0028] The top of the movable cover 2 is provided with a first smoke-blocking structure 8, and the fixed cover 1 is provided with a second smoke-blocking structure 9, which is fastened to the first smoke-blocking structure 8.
[0029] This utility model combines a movable cover and a fixed cover, allowing the movable cover to be moved for easy use. It not only occupies little space but also does not affect the hoisting of ingots. Combined with the smoke-blocking structure, it reduces the escape of smoke and dust and has a good smoke-absorbing effect.
[0030] Figure 2 This is a schematic diagram of a fixed cover. The fixed cover 1 includes a fixed frame 101 and a top cover 102. The top cover 102 is fixed to the top of the fixed frame 101 and is connected to the pipe 3. The pipe 3 is also connected to a main pipe 4. The second smoke-blocking structure 9 is fixed to the inner side of the fixed frame 101.
[0031] The top of the fixed cover of this utility model is provided with another top cover 102, which, together with two pipes 3, can increase the strength and range of smoke extraction. The two pipes are connected to a main pipe 4 and sent to the gas purification processor. The main pipe 4 is connected to a dust removal electric valve for controlling the smoke extraction.
[0032] Figure 3 This is a diagram of the movable cover. Figure 4 yes Figure 3 The side view shows that the movable cover 2 includes a first movable frame 201 and a second movable frame 202. Both the first movable frame 201 and the second movable frame 202 are gantry structures. The first movable frame 201 is higher than the second movable frame 202 and the two are arranged in parallel. A movable top cover 203 is provided on the top. The movable top cover 203 is an inclined structure. The first smoke-blocking structure 8 is provided on the top of the first movable frame 201. The first movable frame 201 is always located inside the fixed cover 1. The walking component 204 is provided at the bottom of the first movable frame 201 and the second movable frame 202.
[0033] The top of the mobile cover of this utility model is inclined, which allows the smoke and dust in the lower area to be sucked away more thoroughly and reduces the accumulation of smoke and dust. The walking component 204 adopts the structure of walking motor and walking wheels, and is equipped with track 5 for movement.
[0034] Figure 5 This is a diagram showing the movable cover moving into the fixed cover. Figure 6 This is a diagram illustrating the removal of the movable cover. Figure 7 yes Figure 5 Enlarged diagram of part A in the middle. Figure 8 yes Figure 6 The enlarged schematic diagram of part B shows that the first smoke-blocking structure 8 includes a first upright plate and at least two first sawtooth structures, the at least two first sawtooth structures being fixed to the first upright plate, and the first upright plate being fixed to the top of the first movable frame 201; the second smoke-blocking structure 9 includes a second upright plate and at least three second sawtooth structures, the at least three second sawtooth structures being fixed to the second upright plate, and the second upright plate being fixed to the fixed frame 101; the at least two first sawtooth structures and the at least three second sawtooth structures are interlocked.
[0035] When the movable hood enters the fixed hood, the two serrated structures separate. When the movable hood is pulled out, the two serrated structures interlock to form an engaging structure. In this way, the interlaced serrated structure reduces the amount of smoke and dust escaping from the gap between the movable and fixed hoods, reduces leakage, and maintains a clean environment.
[0036] This utility model's dust collection hood for the mold repair station is a combination of a movable collection hood and a fixed hood. When using the crane 6 to lift the slab ingot 7 (clump ingot), the movable hood is moved inside the fixed hood. During mold repair, the movable hood is moved out, and the dust collection electric valve (not shown) connected to the main pipe 4 is opened to begin the mold repair work. After the mold repair work is completed, the dust collection electric valve is closed, the movable hood is moved back inside the fixed hood, and the slab ingot 7 (clump ingot) is lifted to the designated area. Dust generated during mold repair inside the movable hood should be cleaned promptly to avoid long-term accumulation that could affect the movement of the movable hood.
[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
