Embodiment
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
Referring to Fig. 1-Fig. 4, a kind of novel pair of air port movable converter secondary flue gas capturing device, it comprises the fume trap cover 1 being arranged in converter 13, described fume trap cover 1 is communicated with outside cleaning shaft by induced exhaust 10; Described fume trap cover 1 comprises front panel 1-1, top board 1-2 and rear panel 1-3, and described front panel 1-1, top board 1-2 and rear panel 1-3 are connected to form a below and have the hollow cell body of opening in turn, and the two ends of hollow cell body are all connected with described induced exhaust 10; Described top board 1-2 is provided with and blocks top board 3, and described in block top board 3 front end be provided with range finder 6, the described top board 3 that blocks is connected with stationary installation 9 by driving mechanism 8, described range finder 6 is by the collapsing length of controller control driving mechanism 8, thereby controls the length of blocking top board 3 and paying top board 1-2; Described front panel 1-1 is provided with blinds blast inlet 2.
In order to reach better trapping effect, can make front panel 1-1 and rear panel 1-3 measure-alike, and make the just dispersal direction to described secondary flue gas of opening of fume trap cover 1.
In order to reach better trapping effect, can top board 1-2 and described in block slide rail 5 be set between top board 3; Can telescoping side plate 4 be set respectively in the both sides of blocking top board 3, the upper surface of telescoping side plate 4 with block top board 3 and be connected, the side of telescoping side plate 4 is connected with the front panel 1-1 of fume trap cover 1, and telescoping side plate 4 can stretch or shrink along with blocking the movement of top board 3.
In the present embodiment, described driving mechanism 8 is hydraulic ram, the piston rod of described hydraulic ram by coupling device 7 with block top board 3 and be connected, the plunger shaft of described hydraulic ram is connected with described stationary installation 9.
When crane crossbeam 11 arrives predetermined position when static (being defined as original state), now fume trap cover 1 and crane crossbeam 11 have a larger gap (see figure 2), and now telescoping side plate 4 is in contraction schedule.
In the present embodiment, described controller comprises signal sample circuit and pilot circuit.Range finder 6 is measured the distance of blocking top board 3 and crane crossbeam 11, then by data transfer to signal sample circuit, after the signal of signal sample circuit receiving range detector 6, signal is passed to pilot circuit, stretching of pilot circuit control driving mechanism 8, realizes the movement of blocking top board 3.
By the effect of slide rail 5, coupling device 7, driving mechanism 8, blocking top board 3 moves forward, press close to crane crossbeam 11, when range finder 6 feedbacks are blocked when top board 3 reaches set(ting)value with the distance of crane crossbeam 11, (set(ting)value is as far as possible little, but should be more than or equal to 0), block top board 3 and stop reach, keep maintaining static (being defined as working order) (see figure 3), now telescoping side plate 4 is in extended configuration.
When the work of converter hot metal charging starts, converter 13 tilts to state in Fig. 3, when iron ladle 12 tilts to start, toward 13 times of falling molten iron of converter, will produce a large amount of high-temperature flue gas.Now fume trap cover 1 exhausting of starting working.Most of flue gas enters in fume trap cover 1 and is pumped from fume trap cover 1 lower openings, but quite a few flue gas escapes and moves upward, move forward owing to blocking top board 3, effectively block the main escape route of flue gas, under the effect of blinds blast inlet 2, escape flue gas enters in fume trap cover 1 and is pumped, and completes secondary trapping, thereby has improved greatly the overall collection efficiency of secondary flue gas.
The useful area coefficient of blinds blast inlet 2 can regulate, thus can adjusting louver blast inlet 2 with the air output ratio of fume trap cover 1 lower openings, make the collection efficiency of whole device reach the highest.
In the time that crane crossbeam 11 leaves fume trap cover 1, the contraction of controller control driving mechanism 8, realizes and blocks top board 3 and get back to the position of original state.
In the utility model, described in block top board lighter weight, the driving force of the driving mechanism configuring requires less, can energy efficient with this.
The utility model is simple in structure, and process for making is not almost affected, and is applicable to newly-built and transformation project, can effectively reduce investment and shorten the transformation cycle.
