A kind of embodiment as said structure: the axis of described air admission hole and horizontal angle are 60 degree, and the opening direction of described air admission hole is for inwardly to be had a down dip by upper.
In above-mentioned a kind of carbon brush for electric machine sintering furnace internal structure, described body of heater and flue all make of stainless steel material.
In above-mentioned a kind of carbon brush for electric machine sintering furnace internal structure, be provided with airspace between the lateral wall of described crucible and flue, the middle part of crucible is provided with the breather pipe of through bottom.
In above-mentioned a kind of carbon brush for electric machine sintering furnace internal structure, bottom described bonnet and on the outside of base, be all radially provided with multiple lock hook, be fixedly connected by locking plate with corresponding lock hook on base bottom bonnet.
The present invention gives prominence to compared to existing technology and useful technique effect is:
Flue tube structure of the present invention is provided with smokejack, and airspace is provided with between each crucible, the dense smoke produced in crucible is used to be discharged by smokejack in time, avoid the situation that dense smoke pollutes carbon brush line, roasting qualification rate can reach 100%, and pitch binder brush can adopt wire plunging to produce simultaneously, and plugging is produced and improve production efficiency than before, decrease waste of material, improve the stability of product quality simultaneously.
Accompanying drawing explanation
Fig. 1 is structure half sectional view of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, with specific embodiment, the invention will be further described, see Fig. 1:
A kind of carbon brush for electric machine sintering furnace internal structure, comprise sintering body of heater and flue 1, described flue comprises bonnet 2, crucible 5 and base 3, the bottom 20 of bonnet is connected by snap close with base, the furnace chamber 4 closed is formed in bonnet and base, multiple crucible 5 has been stacked gradually from the bottom to top in furnace chamber, each crucible all leaves can the gap 12 of inside and outside ventilation, the top of described bonnet is provided with the smokejack 6 furnace chamber 4 and body of heater are communicated with outward, the surrounding of base is provided with draw-in groove 7, the lower end of bonnet is located in the draw-in groove of base, the furnace chamber 4 of bonnet is communicated with outward with body of heater by smokejack 6.Be provided with airspace between the lateral wall of described crucible 5 and flue, the middle part of bonnet 2 is provided with the installation of TC pipe of through bottom.
In said structure, crucible is all connected in flue, and the dense smoke produced under high temperature can be discharged in smokejack along with gap 12 under the draft of admission pressure and smokejack 6, and is discharged in time by smokejack, therefore there is not particle in dense smoke and is attached on carbon brush line.
Described bonnet is the cylinder-like structure of open lower side, and described base is garden plate-like.
Be filled with river sand in described draw-in groove and form sand seal.Avoid extraneous gas to enter, when simultaneously furnace pressure reaches certain pressure, a small amount of cigarette also can be gone out by beach volleyball.
