Abstract
The utility model relates to a novel RH alloy vacuum loading hopper which comprises an upper hopper (1), a lower hopper (2) and a seal tank (5) which are sequentially connected, wherein an upper seal valve (3) is arranged on the upper hopper (1); a vibratory feeder (6) is arranged in the seal tank (5); a lower seal valve (4) is arranged at a discharging port of the seal tank (5); and the loading hopper further comprises an vacuum breaking and pressure recovery valve station (9) connected with the seal tank (5). Compared with the prior art, the lower seal valve is transferred to the discharging port of the seal tank, so that on one hand, the material storage space in the lower hopper is not occupied any more, and one the other hand, a seal ring of the lower seal valve is maintained and replaced conveniently; and at the same time, a pressure extraction port of the vacuum breaking and pressure recovery valve station is transferred to a chute outside the lower seal valve, and the pressure extraction port is very close to the alloy vacuum loading hopper, so that the establishment of a vacuum environment in the alloy vacuum loading hopper can be accelerated.
Description
Technical field
The utility model relates to steel-making RH technology field, more particularly, relates to a kind of novel RH alloy vacuum charging bucket.
Background technology
In the RH vacuum refinement, the alloy of required interpolation through weighing, enters in alloy vacuum charging bucket, after vacuumizing and reaching and all press with vacuum chamber, via oscillating feeder, joins in the molten steel in vacuum chamber.
Traditional alloy vacuum charging bucket as shown in Figure 1, comprises bucket 1, lower bucket 2 and broken sky-multiple pressure valve station 9.Upper bucket 1 is provided with upper sealing valve 3, and lower bucket 2 is provided with lower sealing valve 4, and broken sky-multiple pressure valve station 9 is connected with lower bucket 2.Bottom also is furnished with a vibratory feeder 6 that is arranged in sealed can 5, reaches the purpose of quantitative vacuum charging, and sealed can 5 is connected with the RH vacuum chamber by T-valve 7.This traditional alloy vacuum charging bucket in actual use, has following shortcoming:
(1), the most of structure of lower sealing valve all is positioned at lower bucket, taken time inner bin stock space of bucket, and is for the alloy vacuum charging bucket of low capacity, especially remarkable;
(2), the sealing-ring of lower sealing valve is positioned at alloy vacuum charging bucket inside, check and change very inconvenient;
(3), the foundation of vacuum environment in alloy vacuum charging bucket, pressure is from vacuum system first step condenser, path is far away, pumping speed is limited.
The utility model content
The technical problems to be solved in the utility model is, a kind of novel RH alloy vacuum charging bucket is provided.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of novel RH alloy vacuum charging bucket, comprise the upper bucket, lower bucket and the sealed can that connect successively, on described, struggle against and be provided with upper sealing valve, in described sealed can, be provided with vibratory feeder, the discharge port place of described sealed can is provided with lower sealing valve, and described loading hopper also comprises and the tank connected broken sky of described sealing-multiple pressure valve station.
In novel RH alloy vacuum charging bucket described in the utility model, the discharge port of described sealed can is connected with the RH vacuum chamber by elephant trunk, and the pressure tappings at described broken sky-multiple pressure valve station is arranged on described elephant trunk.
In novel RH alloy vacuum charging bucket described in the utility model, described sealed can is connected with described elephant trunk by T-valve, and the outlet of described T-valve also is provided with seal valve.
Implement novel RH alloy vacuum charging bucket of the present utility model, have following beneficial effect:
(1), the utility model moves to lower sealing valve at the discharge port place of sealed can, no longer takies on the one hand the bin stock space in lower bucket, on the other hand the maintenance of the sealing-ring of lower sealing valve change convenient;
(2), the pressure tappings that breaks sky-multiple pressure valve station can be moved to the elephant trunk place beyond lower sealing valve, pressure tappings, very near alloy vacuum charging bucket, can be accelerated the foundation of vacuum environment in alloy vacuum charging bucket.
The accompanying drawing explanation
The utility model is described in further detail below in conjunction with drawings and Examples, in accompanying drawing:
Fig. 1 is the structural representation of RH alloy vacuum charging bucket in prior art;
Fig. 2 is the structural representation of novel RH alloy vacuum charging bucket.
Embodiment
For technical characterictic of the present utility model, purpose and effect being had more clearly, understand, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
As shown in Figure 2, novel RH alloy vacuum charging bucket of the present utility model comprises upper bucket 1, lower bucket 2 and the sealed can 5 that connects successively.
Upper bucket 1 is provided with upper sealing valve 3, in sealed can 5, is provided with vibratory feeder 6, and the discharge port place of sealed can 5 is provided with lower sealing valve 4.Loading hopper also comprises brokenly sky-multiple pressure valve station 9, and broken sky-multiple pressure valve station 9 is connected with sealed can 5.Broken sky in the present embodiment-multiple pressure valve station 9 can pass into nitrogen in sealed can 5, can also vacuumize simultaneously, realizes the foundation of vacuum environment in alloy vacuum charging bucket.The utility model moves to lower sealing valve 4 at the discharge port place of sealed can 5, no longer takies on the one hand the bin stock space in lower bucket 2, and the maintenance of the sealing-ring of lower sealing valve 4 is changed conveniently on the other hand.
Further, the discharge port of sealed can 5 is connected with the RH vacuum chamber by elephant trunk 10, and the pressure tappings at broken sky-multiple pressure valve station 9 is arranged on elephant trunk 10.Pressure tappings, very near alloy vacuum charging bucket, can be accelerated the foundation of vacuum environment in alloy vacuum charging bucket.
Further, sealed can 5 is connected with elephant trunk 10 by T-valve 7, and the outlet of T-valve 7 also is provided with seal valve 8.
The above is described embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, also can make a lot of forms, within these all belong to protection of the present utility model.
