Description
Technical field
The utility model relates to a kind of material flow device, the material flow device of particularly a kind of metallurgy industry normal pressure or low pressure shaft furnace furnace roof charging system or furnace bottom discharge system.
Background technology
It is that raw material is produced sponge iron that coal gasification normal pressure or low pressure reduction shaft furnace technology mainly adopt pellet.On pellet top charging system and furnace bottom discharge system, all need to install cut-out equipment, so that furnace roof and furnace bottom equipment are overhauled and safeguards, simultaneously critical process main parts such as shaft furnace body of heater are overhauled; Also need logical gases at high pressure to seal on the other hand, scurry leakage outward, cause security incident to prevent coal gas.
The sealing gland equipment and the cut-out equipment of at present direct its furnace roof of reduction shaft furnace technology and furnace bottom have adopted two covering devices respectively, i.e. sealing gland equipment, cut-out equipment.Cut-out equipment is more traditional slide valve mechanism, two covering device cooperatings.
The utility model content
The utility model relate to a kind of simple in structure, possess sealing gland equipment and cut off the material flow device of equipment simultaneously.
To achieve these goals, by the following technical solutions:
A kind of material flow device, comprise the gas inlet pipe that is arranged on sealing gland section side, it is characterized in that: the upper surface of described sealing gland section is provided with material inlet, the size of described material inlet is less than the size of sealing gland section upper surface, the bottom of described sealing gland section is connected with the material cut-off parts with pin hole, be inserted with draw point in the pin hole, also be provided with the end face seal lid on two end faces of described material cut-off parts.
As further optimization, in order to guarantee the ring seal effect, the trapezium structure that the cross section of described sealing gland section is big up and small down.
As further optimization, not overheated for assurance equipment, described sealing gland section outer surface is provided with cooling water channel.
As further optimization, in order to guarantee the separated material effect, described pin hole is two-layer above staggered floor construction.
As further optimization, for the effect of described cooling, the inlet of cooling water channel is positioned at the below of sealing gland section outer surface, and the outlet of cooling water channel is positioned at the top of sealing gland section outer surface.
As further optimization, for the ease of maintenance, the side of described sealing gland section also is provided with manhole.
Structure of the present utility model can be cut off material, and the gases at high pressure of also can jetting carry out air seal.Simple in structure, safe.When needs overhauled process equipment and safeguard, the draw point of available one deck at least inserted the draw point pin hole and will install interior material cut-out, and the prevention material adds or discharges, thereby carries out the maintenance and the maintenance of equipment; Cut off after material makes it stop, gases at high pressure are equally by gas inlet pipe, enter into that material is piled up naturally and air seal is carried out in the interior annular space chamber that forms, prevent that coal gas from scurrying the safety coefficient when improving workman's maintenance and service equipment outward.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is Fig. 1 cutaway view.
Among the figure: part 1 is a gas inlet pipe, and part 2 is a manhole, and part 3 is the material cut-off parts, and part 4 is interior annular space chamber, and part 5 is a material, and part 6 is the draw point pin hole, and part 7 is the end face seal lid, and part 8 is a draw point, and part 9 is a cooling water channel, and part 10 is a material inlet.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As Fig. 1, Fig. 2, shown in Figure 3,
A kind of material flow device, comprise the gas inlet pipe 1 that is arranged on sealing gland section side, the upper surface of sealing gland section is provided with material inlet 10, the size of described material inlet 10 is less than the size of sealing gland section upper surface, the bottom of described sealing gland section is connected with the material cut-off parts 3 with pin hole 6, also is provided with end face seal lid 7 on 3 two end faces of described material cut-off parts.This device can be used in normal pressure or the low pressure reduction shaft furnace, top charging system or furnace bottom discharge system place.Outer scurrying for the device interior reducing gas played sealing function, can also material be blocked at overhaul of the equipments and maintenance phase simultaneously.
The sealing gland function of this utility model is achieved in that the sealing gland section of this device is that the cross section is up big and down small trapezoidal, gases at high pressure spray into from gas inlet pipe 1, when not needing to cut off material, pin hole 6 both ends of the surface seal with end face seal lid 7, and reducing gas is not understood outer scurrying and caused potential safety hazard.Because when this device is worked in furnace top system and furnace bottom discharge system, material enters from material inlet 10, all is full of material in the chamber, because the cross section of sealing gland section is up big and down small, material can't be full of whole cavity fully, an interior annular space chamber 4 is formed at the top in the sealing gland section, and sealing gas forms a blanket gas high pressure endless belt after gas access 1 enters, sealing gas is by the material gap on this cross section, in shaft furnace, purge, prevent that reducing gas from scurrying outward, coal gas is sealed.
Certainly since the size of material inlet 10 less than the size of sealing gland section upper surface, the logistics of Dui Jiing will inevitably form interior annular space chamber naturally, so also can be other shape from the cross section of sealing gland section.
The cut-out function of this utility model is achieved in that opens end face seal lid 7, and draw point 8 is inserted in the pin hole 6 that is at least one deck layout, and the pin hole 6 shown in the figure is that two-layer dislocation is arranged.Feed opening can be run through fully after draw point 8 inserts, also insertion can be connected fully.Draw point 8 shown in the legend is not to run through feed opening fully.Adopt draw point that material is cut off, can in opening-closing process, not produce the blocking-up phenomenon that gets stuck.When blocking material, the reducing gas of also externally scurrying carries out the gases at high pressure sealing.Insert draw point 8 when cutting off material, material 5 piles with whole inner chamber, and this moment, material 5 was blocked.High pressure sealing gas enters around interior annular space chamber 4 by gas inlet pipe 1, rounds and passes material 5 gaps, externally scurries coal gas and seals.
This device makes hull outside that one cooling water channel 9 be arranged by welding or casting.The cooling water channel 9 that this embodiment adopts welding manner to form by at device case outside welding one housing, forms an interlayer as cooling water channel 9 between welded case and the device case; During device busy, cooling water or cold gas enter from the inlet of device hypomere, flow out from the outlet of device epimere.The cooling water system of crust of the device makes that device also can operate as normal in by high-temperature material or cut-out high-temperature material.
