Abstract
A kind of high intensity ventilation cone, monnolithic case is round table-like, inner hollow, upper and lower ends opening, uniform wall thickness, the cone section angle of upper, middle and lower three is consistent, middle one section is sintering metal powder poromerics, and outer wall has a reinforcement with sintering metal powder micropore section one sinter molding, and close section of the sintering metal powder micropore section and upper and lower matter is Jing after cold isostatic compaction, one entirety is sintered directly into by high temperature, as needed the external hardware welding of the close cone Duan Zaiyu of matter.Can also have layer of metal silk screen in the sintering metal powder micropore section inwall, the high intensity ventilation cone avoids close section of sintering metal powder micropore the Duan Yuzhi directly caused unbalanced stress of welding and strength reduction, substantially increase the ability of the pressure-bearing and endurance load of ventilation cone, once sintering metal powder micropore section is damaged, its fragment will not then enter ventilation cone internal blocking pipeline and nozzle, and then improve production efficiency, production cost is reduced, the operation stability of device is improve.
Description
Technical field
The present invention relates to a kind of high intensity ventilation cone, in coal gas chemical industry, the bottom for taper pulverized coal conveying device is pressurizeed and to coal
The fluidisation of powder, prevents from blocking runner.
Background technology
At present, the ventilation cone adopted by coal gas chemical industry, the close cone section of its sintering metal powder micropore Duan Yuqi both sides matter are welded directly together,
And there is no the reinforcement of entirety and the metal gauze of inside, gas is entered by the capillary micropore inside sintering metal poromerics from outside ventilation cone
Inside cone, and work as the inflation of air filling cone alternate, deflation course, the welding bead position between micropore part and matter confidential paper will due to unbalanced stress
Rupture is produced, so as to smash ventilation cone, broken sintering metal powder poromerics fragment falls into,
Cause plant failure run.
The content of the invention
Its special production technology of the invention and internal structure, the bearing capacity and endurance that improve the ventilation cone adopted by coal gasification apparatus are carried
The ability of lotus, reduces its breakage rate, and after the breakage of sintering metal powder poromerics, its fragment will not also enter ventilation cone internal blocking pipe
Line and nozzle, and then improve production efficiency, reduce production cost.
To reach above-mentioned purpose, the solution of the present invention is：
A kind of high intensity ventilation cone, is characterized in that monnolithic case for round table-like, inner hollow, upper and lower ends opening, uniform wall thickness, it is upper, in,
Lower three cones section angle is consistent, and middle one section is sintering metal powder poromerics, can for rustless steel, Hastelloy, monel metal, nickel and
Nickel alloy, titanium or titanium alloy are powder sintered to be formed, and outer wall has the reinforcement with sintering metal powder micropore section one sinter molding, and wherein reinforcement is
Sintering metal powder poromerics, the sintering metal powder micropore section it is close with upper and lower matter cone section Jing after cold isostatic compaction, by high temperature direct sintering
Into an entirety, the as needed external hardware welding of the close cone Duan Zaiyu of matter.
In another embodiment, it is also designed to have one metal wire layer in the sintering metal powder micropore section inwall on the basis of the above
Net, the close section of welding of metal gauze and upper and lower matter, then one is sintered directly into by high temperature with sintering metal powder micropore section Jing after cold isostatic compaction
Individual entirety.

Specific embodiment
With reference to two kinds of embodiments and accompanying drawing, the present invention is described in further detail, to make those skilled in the art with reference to description text
Word can be implemented according to this.
The first embodiment
Be illustrated in figure 2 the present invention a specific embodiment, ventilation cone by 2-1 be top matter it is close cone section, 2-2 be sintering metal powder micropore section,
2-3 is the close cone section composition of bottom matter, and three are bored section uniform wall thickness, and angle is consistent, sintering metal powder micropore section 2-2 cone section 2-1,2-3 close with matter
Jing after cold isostatic compaction, an entirety is sintered directly into by high temperature, so as to avoid close cone section 2-1 of sintering metal powder micropore section 2-2 and matter,
2-3 directly welds the unbalanced stress and strength reduction of generation, and outer wall has and sintering metal powder micropore section one sinter molding reinforcement, this embodiment party
Case reinforcement is the vertical bar shape along generatrix direction, and several are evenly distributed on outer wall circumference radial direction, improves the overall bearing capacity of ventilation cone and resistance to
The ability of fatigue load.
Second embodiment
Be illustrated in figure 3 the present invention another specific embodiment, ventilation cone by 3-1 be top matter it is close cone section, 3-2 be sintering metal powder micropore
Section, 3-3 are metal gauze, and 3-4 is the close cone section composition of bottom matter.Metal gauze 3-3 is welded to into close cone section 3-1 of top matter and close cone section 3-4 of bottom matter first
Inwall on, sintering metal powder micropore section 3-2 again it is close with matter cone section 3-1,3-4 and metal gauze 3-3 Jing after cold isostatic compaction, it is direct by high temperature
Sinter an entirety into.This kind of scheme increased metal gauze 3-3 on the basis of the first embodiment so that the bulk strength of ventilation cone, hold
The ability of pressure energy power and endurance load is improve again, and under some severe operating modes, if once sintering metal powder micropore section 3-2 is damaged,
The interception that its fragment has metal gauze 3-3 will not then enter ventilation cone internal blocking pipeline and nozzle, and then improve production efficiency, reduce production cost,
Greatly improve the stability of plant running.
