Further, between each described material flow gate and supply pipe, be also provided with accordingly bottom high pressure seal valve.
Further, according to the charging capacity of hopper, the quantity of described baiting valve is set to multiple.According to the utility model, by using connected structure, reduce transmission mechanism, equipment is simple, and Maintenance and Repair are convenient, reduced construction investment and the materials consumption expense of top charging equipment simultaneously.Material is flowed through hopper by multiple baiting valves, high pressure batch can, material flow gate and supply pipe, can point single channel or multichannel enter in high pressure shaft furnace, to reduce the segregation of furnace charge.And can meet the shaft furnace working condition requirement of 0.4-0.6Mpa.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.Wherein:
Fig. 1 is according to the structural representation of a kind of high pressure top charging equipment of the present utility model.
Embodiment
Below, by exemplary embodiment, the utility model is specifically described.But should be appreciated that element, structure and the feature in an embodiment also can be attached in other embodiment valuably in the situation that further not narrating.
In conjunction with Fig. 1, it shows a kind of high pressure top charging equipment, comprises hopper 1, for holding furnace charge; At least one baiting valve 3, is connected to the bottom of this hopper 1, for furnace charge in hopper is tending towards evenly, rationally to the cloth in following high pressure batch can, guarantees the symmetry that furnace charge distributes in high pressure batch can, reduces charging segregation; At least one high pressure batch can 5, is connected to the below of baiting valve 3 accordingly; At least one material flow gate 6, is connected to the bottom of this high pressure batch can 5 accordingly, for regulating material Flow Velocity or the material stream time of furnace charge, to guarantee all even reasonableness in cloth process.
Be worth being, at least one supply pipe 8 is connected to the bottom of described material flow gate 6 accordingly with pointing out, and distributes equably at the top of shaft furnace 9 section, and the inside of shaft furnace 9 is stretched in the lower end of described supply pipe 8.Supply pipe is uniformly distributed, to reduce the segregation of furnace charge.
Be preferably, the utility model also has material fluidic distributor 2, is arranged on the inside of this hopper 1, for making furnace charge in dropping process is evenly distributed in hopper, and furnace charge is played to shock absorption.
In order to guarantee the structural compactness of top charging equipment, the receiving opening of described baiting valve 3 is connected to the bottom port of described hopper 1 by connected structure.Meanwhile, the receiving opening of described material flow gate 6 is also connected to the bottom port of described high pressure batch can 5 by connected structure.
In order to guarantee the stopping property of equipment, between described baiting valve 3 and high pressure batch can 5, be also provided with accordingly at least one top high pressure seal valve 4, for when batch can is to sealing coal gas in stove when blanking.In like manner, in order to guarantee the stopping property of equipment, between described material flow gate 6 and supply pipe 8, be also provided with accordingly at least one bottom high pressure seal valve 7.
In the situation that opening baiting valve 3 and top high pressure seal valve 4, the furnace charge in hopper 1 enters high pressure batch can 5, after the furnace charge in hopper all enters high pressure batch can 5, closes baiting valve 3, and at this moment hopper 1 prepares to receive another batch of furnace charge.According to charging capacity, material flow through hopper can point single channel or multichannel enter in high pressure shaft furnace.
Alternatively, the quantity of described material flow gate 6 can be set to multiple.According to the charging capacity of hopper 1, the quantity of described baiting valve 3 and supply pipe 8 can be set to multiple.Meanwhile, the quantity of described top high pressure seal valve 4 and bottom high pressure seal valve 7 also can be set to multiple.Specifically, as shown in Figure 1, according to a kind of specific embodiment of the present utility model, be respectively arranged with four baiting valves 3, four top high pressure seal valves 4, four high pressure batch cans 5, four bottom high pressure seal valves 7, four supply pipes 8.
