Description
Technical field:
The present invention relates to a kind of feeding warehouse, especially a kind of feeding warehouse that is used for the air hermetic kiln.
Background technology:
As calciner, the air hermetic kiln, for example the feeding warehouse of air hermetic kiln and burner hearth adopt and are tightly connected, and the material in the feeding warehouse and the cover plate of feeding warehouse play sealing function to the atmosphere of burner hearth, to reach the purpose of atmosphere protection.But kiln is in calcination process, and burner hearth is inner usually can generate gaseous product, and the gas pressure in the burner hearth is usually far above feeding warehouse; In this case; Gas can enter into feeding warehouse in the traditional feeding warehouse that links to each other with burner hearth, burner hearth, and then causes the material in the feeding warehouse to pollute or poisoning.For example, produce gaseous products such as water vapour in the burner hearth, water vapour will bleed back to feeding warehouse; Because action of thermal difference, easy condensed gas such as water vapour will be condensate in feeding warehouse, cause feeding warehouse inwall ponding; Also sneaked into aqueous water in the material; Make material component generation segregation, even change the proportioning of material, influence the composition of sintered products.It is thick that aqueous water or other condensed liquid can also make the material of feeding warehouse inner drying become sticky, and has a strong impact on the flowability of material, causes mass transport not smooth, and feeding warehouse stops up.
In addition, if kiln is the continous way charging, material needs constantly to replenish in the feed bin.When opening the feeding warehouse cover plate and replenish material, feeding warehouse can descend to the sealing function of burner hearth, and outside air can get into feed bin with material simultaneously, and pressure in the burner hearth and atmosphere can be affected.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of feeding warehouse that is used for the air hermetic kiln that can prevent gas backstreaming, avoid being prone to the condensed gas condensation.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme:
This feeding warehouse that is used for the air hermetic kiln comprises charging replacing section, feed bin part and spiral feeding part, and said charging replacing section is arranged at the top of feed bin part, and said spiral feeding part is arranged at the below of feed bin part.
Sealing when guaranteeing the material warehouse entry; Further; Said charging replacing section comprises push-pull valve and lower plugboard valve, saidly is provided with the protective gas outlet from nearer position, last push-pull valve below, is provided with protective gas inlet A from nearer position, lower plugboard valve top.
In order to prevent that gas backstreaming is to feeding warehouse, easy condensed gas condensation in the burner hearth; Further, said feed bin partly comprises feed bin, and the feed bin top is provided with Pressure gauge; Inwall is provided with high charge level inductor and low material level inductor; Be provided with heater between high charge level inductor and the low material level inductor, said heater top is provided with symmetrical protective gas inlet B and electric motor of shaker, and the below of said low material level inductor is provided with agitating device.
In order to guarantee that material gets into, further, said feed bin is back taper.
In order to prevent that mass transport is stifled bad; Further; Said spiral feeding part comprises protective gas inlet C, non-homogeneous screw feed device, bearing platform and burner hearth; Said protective gas inlet C is arranged on the top of non-homogeneous screw feed device, and non-homogeneous screw feed device one end is connected with burner hearth, and the other end is supported by bearing platform.
Compared with prior art; Usefulness of the present invention is: after being connected in this feed arrangement and the burner hearth, can prevent that feeding warehouse is arrived in gas backstreaming in the burner hearth, especially avoid easy condensed gas such as water vapour to be back to feeding warehouse; Can stop the condensations of easy condensed gas in material such as water vapour; Prevent that material in the feeding warehouse from polluting or poison, and the material can prevent in the feeding warehouse with screw rod transmission the time stops up, realize the totally-enclosed function.
