Description
Technical field
The utility model belongs to sponge iron preparation field, and in particular to a kind of distribution device for producing sponge iron.
Background technique
It is currently used production of sponge iron that retort process, which produces sponge iron,.This method charging when,
Using two concentric circles light wall pipes of different sizes as mold, fine iron breeze is placed between two concentric round tubes, reducing agent with
The mixed material of desulfurizing agent is placed between inside, big round tube and the silicon carbide tank of small round tube, but due to concentric circles light wall pipe and carbon
The limitation of spacing between SiClx tank, charging can only use hand charging, and die location varies slightly, then may cause charging
It is uneven, finally result in gained iron ore concentrate in reduction process burning or reduction be not thorough.In addition, the silicon carbide that reaction is used
Tank will appear after running for a period of time to be hardening cracked or Fragmentation Phenomena, using and replace also for silicon carbide tank make sponge iron preparation process
Middle investment increases.
Utility model content
The purpose of the utility model is to provide a kind of distribution devices for producing sponge iron, exist to solve existing distribution device
The degree of automation is low, the problems such as cloth is uneven.
The technical solution of the utility model is as follows: a kind of distribution device producing sponge iron, including feed bin, sealing-tape machine；Institute
It states feed bin to be made of the first blending bunker, concentrate store, the second blending bunker, the first blending bunker, concentrate store, the second blending bunker
Bottom be equipped with gate valve, the lower section of gate valve is equipped with chute, is equipped with elastic doctor blade, institute at the bottom front lower place of the chute
State and be placed with multiple pallets on sealing-tape machine), the elastic doctor blade is located at the surface of pallet.
The board width of scraping of the elastic doctor blade is less than pallet inside dimensions 2- as a further improvement of the utility model,
10mm。
The length of the elastic doctor blade is 10mm-160mm as a further improvement of the utility model,.
The sealing-tape machine is plain-barreled roll sealing-tape machine as a further improvement of the utility model,.
The zone face of the sealing-tape machine is equipped with anti-slip decorative pattern as a further improvement of the utility model, adhesive tape zone face
Two sides are respectively equipped with a raised rib.Prevent pallet sideslip.
The pallet is square as a further improvement of the utility model, having a size of 20 × 20mm-60 × 60mm,
Pallet inside edge is concave arc shape.
The principles of the present invention are that material is fallen into chute in the pallet that lower section is at the uniform velocity advanced, in front of chute
Elastic scraper strikes off every layer of material, and as pallet travels forward on belt, iron ore concentrate is arranged in the upper and lower reduction
It between agent, is in " sandwich shape " that material distributed pallet goes to reduction furnace reduction.
The utility model has the advantage that
1, using " sandwich " distributing mode cloth, by be arranged in after reducing agent and desulphurizer mixing iron ore concentrate layer it is upper,
Lower two sides increase the contact area of reducing agent and iron ore concentrate, while the reducing gas carbon monoxide that lower layer's reducing agent generates exists
Reduction reaction is participated in when across iron ore concentrate layer, is conducive to the progress of reduction reaction.
2, according to thickness of feed layer difference, each chute front end is provided with elastic doctor blade different in size, meanwhile, pallet used
For outboard square-like, inside edge band concave arc structure, the planarization of institute's bed of cloth ensure that.
3, by adjusting gate valve and the sealing-tape machine speed of service, the uniformity and stability of cloth be ensure that.Meanwhile adhesive tape
Machine zone face is equipped with anti-slip decorative pattern, prevents the skidding of pallet, and sealing-tape machine zone face both sides are provided with the rib of protrusion, can prevent pallet
Sideslip.
4, replace traditional manual concentric circles tinning method, the degree of automation greatly improves, and labor intensity is substantially reduced.Together
When, traditional silicon carbide tank is replaced with stainless steel pallet, has saved cost.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of distribution device for producing sponge iron；
Fig. 2 is the side view of Fig. 1.
Specific embodiment
The substantive content of the utility model is further illustrated with example below, but the content of the utility model is not limited to
This.
As shown, a kind of distribution device for producing sponge iron, including feed bin, sealing-tape machine 8；Feed bin is by the first blending bunker
1, concentrate store 2, the second blending bunker 3 composition, the first blending bunker 1, concentrate store 2, the second blending bunker 3 bottom be equipped with it is slotting
Plate valve 4, the lower section of gate valve 4 are equipped with chute 5, elastic doctor blade 6 are equipped at the bottom front lower place of chute 5, is placed on sealing-tape machine 8
Multiple pallets 7, elastic doctor blade 6 are located at the surface of pallet 7.
Elastic doctor blade 6 scrapes board width less than pallet inside dimensions 2-10mm.Elastic doctor blade can be manual according to thickness of feed layer
Setting carries out up and down adjustment, and with the increase of thickness of feed layer, elastic doctor blade is gradually shortened.The effective length of elastic doctor blade is
